Conveyor belt connections play an important role in the performance of the conveyor belt in the transfer process, which can be implemented in different ways. Before starting and using the conveyor belt, it is necessary to install the belt part of this device accurately on it, for this it is necessary to connect the two ends of the belt properly and properly. To connect the two ends of the conveyor belt, special materials, parts and accessories are used, whose material and structure can be different depending on the type of conveyor belt connection.

The connection of the two ends of the belt, depending on the type of connections used in its implementation, must be done based on specific instructions so that the connection process has the necessary quality, efficiency and durability. Considering the high importance of the correct connection of the conveyor belt and the important role of this connection in the operation of the conveyor belt, in this article we intend to introduce the mechanical connection of the conveyor belt, the types of mechanical conveyor belt connections, the advantages of this type of connection, the introduction of devices or vulcanization, types Apparatus, the necessary conditions for the implementation of apparatus and the appropriate and necessary tools for this work, we hope that these materials will be of interest and use to you, the audience.

Conveyor belt mechanical connection

One of the common and practical types of connection for assembling two ends of a conveyor belt or conveyor belt is a mechanical connection, which uses specific materials and tools. Conveyor joints of mechanical type have a special structure and their selection is done based on the length, width, thickness and amount of belt tension and such things.

This type of connection is mostly used in connecting the two ends of manjidi belts due to its features and capabilities. The mechanical connection of the conveyor belt has a short implementation process and simpler tools and equipment are used in its implementation. Finally, it is possible to use mechanical conveyor belt connections in environments with limited access and special environmental conditions (high temperature and humidity) and this also facilitates their implementation process.

Types of mechanical conveyor belt connections

Different mechanical connections are used in the conveyor or conveyor belt, among which we can refer to sheet fasteners, hinged fasteners, and sheet fasteners with flexible matrix, which will be introduced and reviewed in the following.

Sheet fasteners of mechanical type conveyor joints

In this type of connection, sheet fasteners are used for the mechanical connection of the conveyor belt. By using these fasteners, a strong and resistant connection can be created in the conveyor belt, which has high durability and longevity. Due to its design, this type of connection prevents fine-grained materials from falling during transportation. From the application of sheet fasteners, we can mention their use in mines and steel factories. Solid-plate segment fasteners are usually used in permanent conveyor belt connections, and for this reason, working with these fasteners in temporary conveyor belt connections is not recommended. These fasteners can be installed diagonally or in a heptagon pattern, and screws or rivets can be used to connect them.

Hinged fasteners of mechanical type conveyor belt connections

Among other types of mechanical connection of the conveyor belt, we can mention the connection using hinge fasteners, in which a steel belt consisting of upper and lower plates is used. This belt, which is connected to metal rings on one side, is placed on two edges of the belt. Screws or rivets are used to connect hinge fasteners to the belt, and finally the belt is connected by passing the pin through the rings.

The structure of hinged fasteners is in the form of continuous belts that are designed according to the width of the belt. By connecting hinge fasteners, it is possible to separate the belt when needed by removing the pin, which allows the belt to be removed from the conveyor system according to the need for short, long work or for repairs.

Sheet joints with flexible matrix

Among other practical methods in the mechanical type of conveyor belt joints, we can mention the use of sheet joints with a flexible matrix in these belts. For this, self-tapping screws are passed through a matrix with I or H profile. In order to implement this connection, it is necessary to cut the two edges of the belt diagonally and then use an H-like reinforcing rubber matrix inside its empty space.

After covering the entire width of the conveyor belt with the matrix, it is necessary to tighten the joint with screws, for this purpose, a specific number of screws are used for each meter of belt width. By fully covering the space between the two edges of the belt during connection, this matrix prevents the material from leaking on the belt during transportation. The sheet connection with flexible matrix is ​​usually used to connect fabric belts and has a wide application in this field.

Advantages of conveyor belt mechanical joints

The use of mechanical conveyor belt connections has many advantages, which makes these connections widely used in the structure of conveyor belts and for connecting them. The first advantage of this type of connections is their ability to be separated when needed, which will be easy to implement. So, executive agents can make changes in the length of these belts with minimal trouble at any time.

In addition, the use of mechanical conveyor belt connections shortens the downtime of the conveyor belt and transmission system; Because this type of connections can be connected in a short time due to the simple design and implementation method, and this also shortens the process of connecting the conveyor belt and speeds up the process of starting it. In addition, this type of connection is cheap and the inspection process is simple and easy.

Apparatus or vulcanization in conveyor joints

Among other types of conveyor belt connections that are widely used in connecting belts, we can mention apparatus or vulcanization, which is a specialized method and its implementation requires sufficient knowledge and special equipment in this field. If the apparatus or vulcanization process is not done according to the implementation principles, or if the proper equipment is not used in its implementation, the process of connecting the conveyor belt may not be done correctly.

In such a case, the desired belt does not have the necessary efficiency and durability and may be associated with the risk of getting stuck in the machine, wear and tear. Apparatus or conveyor belt vulcanization will be applicable in two forms, cold apparatus and hot apparatus, in each of which unique tools and specific implementation principles are used. In the following, we will introduce and review more of them.

Conveyor belt cold apparatus

Among the practical types of conveyor belt connections by the apparatus or vulcanization method, cold apparatus can be mentioned, in which connecting agents such as glue are used. By creating a chemical reaction at the two ends of the belt, the bonding agent provides the conditions for their connection, and there is no need to use pressure to connect. Cold devices are usually used in the connection of conveyor belts, and in its implementation, less equipment is needed compared to hot devices.

Also, cold apparatus is cheaper compared to its hot type and has a faster execution process. However, this type of apparatus has lower strength and durability compared to warm apparatus. One of the common failure modes of cold equipment in conveyor belt connections is the creation of a gap in its connection area, which is caused by the wear of the adhesive.

Conveyor belt heating apparatus

Conveyor belt hot apparatus is one of the most widely used apparatus methods in working with this equipment, which is also known by other titles such as hot splicing and hot vulcanization. In hot devices, thermal devices and strong adhesives are used to connect the two ends of the conveyor belt, and because of its high efficiency and strength, it is called as the best type of device in connecting conveyor belts or conveyor belts.

However, the cost of running hot apparatus is high compared to its cold type, and due to its longer execution process, it causes more stoppage of the production line during its execution. In the warm apparatus, Lewis operation is used to effectively connect the edges of the belt, which greatly contributes to the strength and durability of the joint. In general, warm appliances are more specialized compared to cold appliances and require more precision and skill.

Regarding vulcanization of the conveyor belt, the almex website said that the vulcanized splice is the process of connecting the two ends of the belt together by applying uniform pressure and temperature.

Necessary conditions for the implementation of apparatus in conveyor belt connections

Before implementing the devices in the conveyor belt connections, it is necessary to clean the surface of the belt from any pollution, including oil, fine materials, etc. The second case is related to the glue used in the implementation of the apparatus, which should have the necessary compatibility with the conveyor belt. Conveyor belt apparatus operation should be done by professional and trained people, and in its implementation, special tools and equipment should be used.

Also, the operation of the apparatus should be done in a suitable space with easy access so that the implemented apparatus has the necessary quality and efficiency. Apparatus process, especially the hot type, is time-consuming and it is necessary to devote enough time to its implementation and not to use the belt immediately after implementation. Applying any kind of pressure to the belt immediately after the apparatus due to the lack of complete preparation of the belt may weaken the joint and ultimately cause its failure and tear.

Tools required for hot apparatus in conveyor joints

Special tools are used in hot conveyor belt apparatuses, each of which plays an important role in the performance quality of the apparatus process. Among these tools and equipment are vulcanizer (press vulcanizer), belt peeling tool, belt tensioner clamp, simple and needle roller, belt cutter, electric sub, hammer, gas pliers, plumb bob, engineering meter, glasses. Safety, nails and chalk for marking pointed out.

Of course, the use of these seemingly simple tools requires enough experience and skill to make the conveyor belt hot apparatus process with high precision and the expected quality. Any carelessness in the implementation of hot devices and conveyor belt connections in this way reduces the quality and strength of the joint in the belt, which will be associated with the possible failure of the belt and financial losses.
