Description

Technical Field

[0001] The utility model belongs to the technical field of leather processing equipment, and specifically relates to a leather processing device with high tensile strength. Background Art

[0002] A bonding machine is an essential equipment for bonding fabrics and hot pressing bonding in the garment manufacturing industry, and can also be used for heat shrinkage setting of various fabrics. Different fabrics and different substrates are stacked in multiple layers with adhesives such as glue and then subjected to hot pressing operations.

[0003] In the prior art, the hot pressing of leather materials generally involves placing two or more materials to be processed on a feeding rack, first performing preliminary lamination with adhesives such as glue, and then entering a pressing and bonding box arranged on a workbench for hot pressing and bonding. However, the adhesive usually has the defect of "hot sticky and cold brittle". Due to the certain distance between the feeding rack and the pressing and bonding box, the adhesive of the pre-laminated leather will start to solidify before entering the pressing and bonding box, resulting in poor bonding during the pressing process and causing the leather to crack and delaminate during the stretching process, affecting the product quality. Summary of the Invention

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a leather processing device with high tensile strength.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: A leather processing device with high tensile strength includes an installation housing. The installation housing includes two side plates. Between the front ends of the two side plates, two groups of guide roller sets are arranged. Each group of guide roller sets includes multiple guide rollers. The two groups of guide roller sets are symmetrically arranged, and the distance between the guide rollers in the two groups of guide roller sets gradually decreases from front to back. The two ends of the guide rollers in the two groups of guide rollers are rotatably connected to the two side plates on both sides. Between the two side plates between the two groups of guide roller sets, a hot air drying box is arranged. The left and right ends of the hot air drying box are fixedly connected to the two side plates on both sides. Between the two rack plates behind the two groups of guide roller sets, two heat preservation and heating plates are arranged. The two heat preservation and heating plates are symmetrically arranged, and the left and right ends are fixedly connected to the two side plates on both sides.

[0006] Preferably, on the two side plates corresponding to the rear sides of the two groups of guide roller sets, a group of air suction boxes are arranged respectively.

[0007] Preferably, the hot air drying box is arranged in the middle position between the two groups of guide roller sets, and the air outlet is arranged towards the rear side.

[0008] Preferably, a discharge air pipe is connected to each of the two air suction boxes.

[0009] The beneficial effects of the present utility model are as follows: By providing a hot air drying box, the binder on the punch of the leather material before pressing is heated to the required temperature, and the binder that may have initial setting is heated to restore it to a hot and sticky state, so that the leather materials can be bonded more tightly, thereby improving the tensile strength of the leather materials; By providing a heat preservation heating plate, the bonded leather materials can be continuously heat-preserved, and the leather materials and the binder can be cooled slowly, thereby improving the connection strength between the two.

[0013] The technical solutions of the present utility model will be further specifically described below through embodiments and in conjunction with the drawings.

[0014] Embodiment: A leather processing device with high tensile strength, as Figure 1 - Figure 2 shown, includes a mounting housing 1. The mounting housing 1 includes two side plates 2. Between the front ends of the two side plates 2, two groups of guide roller sets 3 are provided. Each group of guide roller sets 3 includes multiple guide rollers 3. The two groups of guide roller sets 3 are symmetrically arranged, and the distance between the guide rollers 3 in the two groups of guide roller sets gradually decreases from front to back. The two ends of the guide rollers 3 in the two groups of guide rollers 3 are rotatably connected to the side plates 2 on both sides. Between the two side plates 2 between the two groups of guide roller sets 3, a hot air drying box 4 is provided. The left and right ends of the hot air drying box 4 are fixedly connected to the side plates 2 on both sides. Between the two rack plates behind the two groups of guide roller sets 3, two heat preservation heating plates 5 are provided. The two heat preservation heating plates 5 are symmetrically arranged, and the left and right ends are fixedly connected to the side plates 2 on both sides.

[0015] On the two side plates 2 corresponding to the rear sides of the two groups of guide roller sets 3, a group of air suction boxes 6 are provided; The hot air drying box 4 is arranged at the middle position between the two groups of guide roller sets 3, and the air outlet is arranged towards the rear; A exhaust duct 7 is connected to each of the two air suction boxes 6.

[0016] Principle of the utility model: During use, two layers of fabrics coated with adhesive that need to be bonded are introduced through two groups of guide rollers in three groups. The leather material is heated by the hot air drying box body 4 to make the connection between the adhesive and the leather material closer, and at the same time improve the ductility of the adhesive. The guide rollers 3 at the rear end squeeze and bond the two pieces of heated leather materials, and the heat preservation heating plate 5 at the rear side keeps the leather material warm continuously, slowing down the cooling time and avoiding the insufficient connection between the adhesive and the leather material during rapid cooling.
