Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] see figure 1 , a PU edge sealing conveyor belt edge sealing equipment, including the first pressure roller 3, the second pressure roller 4, the main roller 7, at least one guide roller 5; the first pressure roller 3, the second pressure roller 4, at least A guide roller 5 tensions the pressurized steel belt 6, and one of them is a power roller; a main roller 7 is arranged between the first press roller 3 and the second press roller 4, and the fabric guide roller 7 and the steel belt 6 There is a set pre-tightening force between them; the fabric and PU glue enter the edge banding equipment from between the main roller 7 and the first pressure roller 3, and pass from the second pressure roller 4 to the fabric roller 7 under the guidance of the steel belt 6. The space is separated; the width of the PU glue is greater than the width of the ...

Abstract

The invention relates to a manufacturing device of a PU edge-sealed conveyer belt. The manufacturing device of the PU edge-sealed conveyer belt comprises a first press roller, a second press roller, amain roller and at least one guide roller. A pressurized steel belt is tensioned by the first press roller, the second press roller and the guide roller, and one of the first press roller, the secondpress roller and the guide roller is a power roller. The main roller is arranged between the first press roller and the second press roller. Set pre-tightening force exists between a fabric guide roller and the steel belt. Fabric and PU adhesive enter an edge sealing device from the space between the main roller and the first press roller and leave from the space between the second press roller and the fabric guide roller under the guide of the steel belt. The width of the PU adhesive is larger than that of the fabric. The conveyer belt fabric does not need to be provided with a groove, so that raw material waste is avoided; materials of the fired guide strip needed by an original technology are saved; the steps of forming a groove in the conveyer belt and additionally firing the guide strip are omitted, the whole work period of production of the edge-sealed conveyer belt is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a PU edge-banding conveyor belt manufacturing process and equipment, belonging to the technical field of PU conveyor belts. Background technique [0002] Polyurethane (PU) conveyor belt, as a light-duty conveyor belt, has been widely used in the food and electronics industries due to its advantages of light weight, long life, and good wear resistance. However, due to the friction between the polyester fabric (such as polyester) on the side of the PU conveyor belt and the equipment during application, the polyester fabric will be worn and dropped, and it will be adsorbed under the action of static electricity, which will affect production safety. Conveyor belt of a type structure; [0003] Generally, wear-resistant polyurethane is used as the edge sealing material to completely cover the exposed polyester fabric on the side, so that the side is rubbed against the equipment with wear-resistant polyurethane, which is not easy to ...
