The Role Of Adding Hemming To PVC Conveyor Belt

Detailed explanation of PVC conveyor belts and hemming process

In modern industry, PVC conveyor belts have almost become an indispensable and important equipment in many industries, including electronics, food, medicine, printing and other fields. The special needs of some industries have also prompted the widespread application of hemming conveyor belts. So, how are hemming conveyor belts made? What unique functions does it have?

How to make hemming conveyor belts

There are usually two processes for making hemming conveyor belts:

1. Use hemming strips for hemming

Separate the yarn layer and the rubber surface: Peel off 20 mm of the bottom yarn of the PVC conveyor belt and 15 mm of the middle yarn layer.

Edge banding: Use edge banding strips to cover the edge, and keep a distance of 10mm between the edge banding strip and the edge of the conveyor belt.

Hot melt process: The edge banding strips are firmly combined with the conveyor belt through the hot melt process to ensure that the edge banding does not easily fall off.

Material selection: It is recommended to use a PVC conveyor belt with a thickness of more than 3mm, so that the appearance after edge banding is more beautiful, but it can also be adjusted according to customer needs.

2. Use rubber surface for edge wrapping

Gauze layer treatment: Peel off 30mm of the bottom yarn of the conveyor belt.

Wrapping process: Directly wrap the edge with the surface rubber surface. Use the hot melt process to wrap the edge and the conveyor belt as a whole.

Effect guarantee: This method can also avoid the problem of edge sealing falling off, and the effect is long-lasting and stable.

The role of PVC conveyor belt with edge wrapping:

1. Prevent edge wear

Edge wrapping can protect the edge of the conveyor belt and avoid wear caused by friction with the frame, roller, or other equipment during use, thereby extending its service life.

2. Prevent delamination and cracking

When used for a long time, the edge of the PVC conveyor belt is prone to separation or cracking between layers due to uneven force or friction. Edge wrapping effectively avoids these problems and ensures the overall strength and stability of the conveyor belt.

3. Prevent material leakage

If the conveyor belt is used to transport powdery, granular or liquid materials, edge wrapping can play a sealing role to prevent materials from leaking from both sides of the conveyor belt and improve conveying efficiency.

4. Enhance beauty and neatness

Edge wrapping makes the edge of the conveyor belt smoother and more beautiful, especially in some occasions where the appearance of the conveyor belt is required to be higher, it looks more professional and standardized.

5. Improve safety

Edge wrapping reduces the burrs or sharp parts of the conveyor belt edge, which can prevent operators from being scratched by contact with the conveyor belt and improve the safety of operation.

Application and function of edge wrapping conveyor belt

Edge wrapping conveyor belts are mainly used in some industries with high environmental requirements, including the following fields:

1. Electronics industry

The operating environment is required to be clean and dust-free during the production and processing of electronic products. Ordinary conveyor belts may generate dust due to friction during operation, while edge-wrapped conveyor belts effectively reduce the generation of dust through the coating process, ensuring the stability of the dust-free environment.

2. Food industry

The food industry has strict requirements on hygiene standards. The seamless connection design of edge wrapping conveyor belts can effectively avoid the residue of dust and impurities, while ensuring the cleanliness and safety of the conveying process.

3. Other industries

In addition to the electronics and food industries, pharmaceutical, printing and other fields may also use edge wrapping conveyor belts according to actual needs to meet specific production requirements.

Through reasonable edge design, PVC conveyor belts can not only improve performance, but also better adapt to the needs of different environments, providing efficient and reliable support for production.
