Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, specifically to an edge sealing device for leather processing. Background Technology

[0002] In leather processing, edge sealing is a key process, mainly used to treat the exposed edges of leather after cutting. Through a series of treatments, the edges are made smooth, neat, and durable, while improving the appearance and texture of the finished product. In leather product manufacturing, the cutting and processing of leather edges is a key step that affects the quality of subsequent edge sealing. Existing edge-cutting equipment is cumbersome to adjust the position and height of the cutter when dealing with leather materials of different thicknesses and sizes. It often requires disassembling parts or changing tooling, which is not only time-consuming and labor-intensive, but also difficult to guarantee adjustment accuracy and has poor adaptability, thus limiting the scope of application of the equipment. Therefore, an edge-sealing device for leather processing is proposed. Utility Model Content

A spring 26 and a damper 25 are fixedly installed on the inner side of the extrusion frame 21. The bottom surfaces of the spring 26 and the damper 25 are fixedly connected to the top surface of the moving frame 22. The spring 26 is initially in an extended state. A fixed sleeve 211 is fixedly installed on the top surface of the moving frame 22. The inner side of the fixed sleeve 211 is slidably connected to the outer wall of the connecting frame 210. An extrusion screw 212 is threaded through the outer wall of the fixed sleeve 211 and extends to the inner side of the connecting frame 210. Two sets of edge cutting mechanisms 2 are provided.

A lifting frame 39 is provided on the inner side of the fixed frame 31. A conveying roller 37 is rotatably mounted on the inner side of the lifting frame 39 through a bearing seat 2. A servo motor 36 is fixedly mounted on the outer wall of the lifting frame 39.

[0015] In use, the cutting mechanism 2 and the conveying mechanism 3 work together to cut the edges of the leather before sealing.

When the leather is conveyed to the bottom of the extrusion rollers 29, the extrusion rollers 29 press the leather under the elastic force of the spring 26 and the buffer of the damper 25 to prevent it from shifting and wrinkling, and to ensure the cutting accuracy. The cutting blade 27 of the edge-cutting part is responsible for cutting the edge of the leather. The connecting frame 210 slides in the fixing sleeve 211. The connecting frame 210 can be fixed by turning the extrusion screw 212. The height of the cutting blade 27 can be adjusted to meet the processing requirements. When the leather passes through the cutting blade 27, the cutting blade 27 cuts the edge of the leather. After cutting, the leather enters the conveying mechanism 3 for conveying. Rotating the nut 32 can adjust the height of the conveying roller 37. The nut 32 cooperates with the second threaded rod 33 to drive the lifting frame 39 to move along the limit rail 34. The limit plate 35 ensures its stability. After the servo motor 36 is started, it drives the conveying roller 37 to rotate. The outer anti-slip strip 38 increases the friction and drives the leather to be conveyed smoothly.
