Description

Technical Field

[0001] The utility model relates to the field of conveyor belt production, in particular to a conveyor belt rubber layer laminating device. Background Art

[0002] PVC conveyor belt, full name polyvinyl chloride conveyor belt, is a non-metallic composite material conveying equipment made of polyvinyl chloride resin as the main raw material; PVC conveyor belt has excellent wear resistance, oil resistance, corrosion resistance, anti-slip, weather resistance and aging resistance, and can work stably in various harsh environments.

[0003] The processing flow of PVC conveyor belts mainly includes the following steps: raw material preparation, fabric processing, adhesive layer lamination, cooling and shaping, cutting and trimming, special processing, quality inspection, packaging and storage; among them, adhesive layer lamination is one of the important steps in the processing of PVC conveyor belts. Specifically, PVC material is coated on the pre-treated fabric through a specific process to form a semi-finished conveyor belt.

[0004] Existing PVC conveyor belt adhesive layers are usually laminated using laminating rollers to extrude and laminate the conveyor belt components. During production and observation, it was found that excess glue would be squeezed out from the edge of the conveyor belt and remain on the surface of the laminating roller, which would contaminate the surface of the laminating roller and affect its subsequent conveyor belt laminating work.

[0005] Therefore, in order to solve the above problems, a conveyor belt rubber layer laminating device is proposed. Utility Model Content

[0010] Preferably, the middle part of the second transverse plate is rotatably connected to a plurality of rotating wheels; the rotating wheels are located between the laminating roller and the scraper; when the electric push rod is started, the first transverse plate will carry the second spring telescopic rod and the second transverse plate to approach the laminating roller, the second transverse plate will come into contact with the laminating roller, and the rotating wheels will also come into contact with the laminating roller, and the rotating wheels will rotate under the action of friction, so that the sliding friction between the second transverse plate and the laminating roller is converted into rolling friction, thereby reducing the friction between the second transverse plate and the laminating roller.

[0011] Preferably, a plurality of sponges are fixedly connected to the middle of the rotating wheel; the sponges are arranged in an array; when the rotating wheel and the laminating roller come into contact, the sponges will also come into contact with the laminating roller and clean its surface, thereby reducing the fiber impurities remaining on its surface and improving the smoothness of the laminating roller surface.

[0012] Preferably, a plurality of circular holes are opened in the middle of the first transverse plate; an air pipe is connected to the middle of the first transverse plate; when the scraper cleans the laminating roller, the air pipe can be connected to a hot air blower so that the hot air flow passes through the air pipe into the interior of the first transverse plate, and then the air flow is ejected from the circular holes and reaches the surface of the scraper and the laminating roller, so that the device heats the laminating roller and the scraper, so that the solidified glue on the surface of the laminating roller will be melted, thereby improving the convenience of cleaning the glue on the scraper surface by the laminating roller.
