Description

Technical Field

[0001] This utility model belongs to the field of leather bag processing technology, specifically relating to a leather cutting device for processing backpacks. Background Technology

[0002] In existing leather cutting processes, the leather surface is not flat and wrinkles remain after cutting, affecting the accuracy of the cutting. The "Leather Processing Cutting Device" disclosed in application number "CN202220985388.5" is an increasingly mature technology. It involves laying the leather on a cutting bed surface, fixing one end with a bracket, extending a hydraulic rod to lower a pressing frame. During descent, the pressure roller contacts the leather surface. A first reciprocating motor drives a first lead screw to move a first threaded sleeve, which in turn moves a moving frame, thus moving one side of the pressure roller box to flatten the leather surface and smooth out wrinkles. However, this device still has the following drawbacks: in actual use, leather cutting can only be done by placing a single piece for flattening; after each cutting, the piece of leather to be cut needs to be manually replaced; and after cutting, the finished product needs to be manually removed from the cutting groove, resulting in low processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a leather cutting device for backpack processing, which aims to solve the problems of low processing efficiency in the prior art, where leather cutting can only be done by placing a single piece of leather flat, and after each cutting, the single piece of leather to be cut needs to be replaced manually, and the finished product needs to be manually removed from the cutting groove.

[0004] To achieve the above objectives, this utility model provides the following technical solution: It includes a transport platform, with a raw material conveying frame on one side and a waste material winding frame on the other side. First synchronous electric slide rails are provided on both sides of the transport platform. A cutting frame is slidably connected to the outer side of the first synchronous electric slide rails. An adjusting electric slide rail is slidably connected to the top of the cutting frame. A laser cutting tool is slidably connected to one side of the adjusting electric slide rail. A winding shaft is rotatably connected to one side of the waste material winding frame. A pressure roller is rotatably connected to the top of the other side of the waste material winding frame. A finished product collection box is provided at the bottom of the other side of the waste material winding frame.

[0005] In one embodiment of the leather cutting device for backpack processing of this utility model, the top of the transport platform is provided with a second synchronous electric slide rail on both sides, and an operating frame is slidably connected to the top of the second synchronous electric slide rail. A micro synchronous motor is provided on one side of the operating frame, and a swing rod is fixedly connected to the output end of the micro synchronous motor through one side of the operating frame. A flattening wheel is provided at one end of the swing rod.

[0006] In this solution, a micro synchronous motor rotates a swing arm, and a flattening wheel presses down on one side of the leather. The operating frame is moved by a second synchronous electric slide rail, which moves the flattening wheel. As the flattening wheel moves, it flattens the leather surface, reducing wrinkles.

[0007] In one embodiment of the leather cutting device for backpack processing of this utility model, a raw material shaft is rotatably connected to one side of the raw material conveying frame, and an extrusion shaft is rotatably connected to the top and bottom of the other side of the raw material conveying frame.

[0008] In this scheme, the leather raw material is wound on the raw material shaft, and the leather to be processed is transported by rotating the raw material shaft. The leather is squeezed and flattened by two extrusion shafts to reduce wrinkles during transportation.

[0009] In one embodiment of the leather cutting device for backpack processing of this utility model, the top four corners of the second synchronous electric slide rail are provided with synchronous electric telescopic rods, and the top of the synchronous electric telescopic rods is provided with limiting pressure plates.

[0010] In this solution, during use, after the leather is transported to the surface of the transport table, the second synchronous electric slide rail presses down the limiting plate to stop the leather transport, presses down the area of ​​the leather that needs to be cut, and keeps the cutting area flat. At this time, the laser cutting tool cuts the flat area, and the cutting position of the laser cutting tool is adjusted by the first synchronous electric slide rail and the adjusting electric slide rail.

[0011] In one embodiment of the leather cutting device for backpack processing of this utility model, the surface of the pressure roller is provided with a plurality of extrusion protrusions.

[0012] In this solution, when the winding shaft winds up the cut leather, the leather comes into contact with the surface of the pressure roller and drives the pressure roller to rotate. At this time, the extrusion protrusions on the surface of the pressure roller push the cut part out of the groove cut into the surface of the leather, and the finished product falls into the finished product collection box for centralized collection.

[0013] In one embodiment of the leather cutting device for backpack processing of this utility model, a servo motor is provided on one side of the raw material shaft and the winding shaft, and the output end of the servo motor passes through one side of the raw material shaft and the winding shaft and is fixedly connected to one end of the winding shaft and the raw material shaft respectively.

[0014] In this solution, a servo motor rotates the raw material shaft to transport the leather material. After cutting, the servo motor rotates the winding shaft to recycle the cut leather material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) The leather is squeezed during transportation by two extrusion shafts to reduce wrinkles during transportation. At the same time, the electric telescopic rod presses down the limiting plate to stop the leather transportation, press down the area of ​​the leather that needs to be cut, and keep the cutting area flat.

[0017] 2) The cut leather is wound up by the servo motor rotating the winding shaft on the waste winding rack. At this time, the leather comes into contact with the surface of the pressure wheel and drives the pressure wheel to rotate. The extrusion protrusions on the surface of the pressure wheel push the cut part out of the groove cut into the surface of the leather. The finished product falls into the finished product collection box for centralized collection. Attached Figure Description
