Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belt edge sealing equipment, in particular to a PU conveyor belt edge sealing equipment. Background Art

[0002] PU conveyor belt is a conveying product with artificial polyurethane fabric as the load-bearing skeleton and the coating layer made of polyurethane resin. Polyurethane (PU) is the raw material for the production of conveyor belts. The product formula is scientific and reasonable, meets food hygiene standards and can be in direct contact with food. It has a moderate color and no odor. It not only has the characteristics of high tensile strength, good bending, lightness, thinness, and toughness of ordinary conveyor belts, but also is oil-resistant, non-toxic, hygienic, and easy to clean. This type of conveyor belt fully complies with the US FDA hygiene standards, is wear-resistant, and resists physical aging. It is a durable conveying product.

[0003] In order to avoid the fuzz on both sides of the PU conveyor belts and cause the fuzz to contaminate food, many existing PU conveyor belts for food use edge sealing technology on both sides. The main process is to turn the plastic side material of the PU conveyor belt down and pre-bond it with glue, and then use hot melt to heat it so that the flange and the PU conveyor belt are welded into a whole, thereby completing the edge sealing process of the PU conveyor belt.

[0004] The edge sealing hot melt machine is the main processing equipment in the existing PU conveyor belt processing. It mainly prevents the PU conveyor belt from being placed on the support platform, and adjusts the side of the PU conveyor belt to be under the electric heating plate of the hot melt machine, and then starts the electric heating plate to move down to press the flange and heat and melt. During the use of the above existing conveyor belt edge sealing equipment, the applicant found that:

[0005] 1. When the side edge of the PU conveyor belt is sealed, the side edge of the PU conveyor belt needs to be accurately heated manually, and there is a lack of accurate positioning structure.

[0006] 2. In addition, many existing edge banding supports have fixed widths. When encountering some wider conveyor belts for edge banding, the supports cannot be fully supported, resulting in a lack of support on one side of the conveyor belt, causing the side of the conveyor belt that needs edge banding to warp, which is not conducive to processing quality. In order to solve the above-mentioned problems, a PU conveyor belt edge banding device is provided. Utility Model Content

The electric heating plate 5 is arranged in the supporting shell 3. In this structure, the supporting platform 1 with legs 2 is used to support the PU conveyor belt that needs edge sealing, and then the electric heating plate 5 is driven by starting the cylinder 4 to press the flange that has been adhered to the back of the PU conveyor belt by glue, and then the electric heating plate 5 is started to heat and melt, so that the flange is welded to the back of the PU conveyor belt, thereby realizing the edge wrapping processing of the side of the PU conveyor belt.

[0031] When encountering a wider PU conveyor belt edge sealing, the personnel can pull the pull plate 9 outward, and the pull plate 9 will drive the slide plate 8 in the embedded groove 7 to move outward, thereby expanding the supporting width of the supporting platform 1. At the same time, the pull plate 9 will drive the locking rod 11 to slide on the guide seat 12.
