Description

Technical Field

[0001] This utility model relates to the field of leather technology, and in particular to a leather peeling device for a leather punching machine. Background Technology

[0002] When using anti-slip paper with a leather punching machine, the leather tends to stick to the paper after punching, making it inconvenient to collect the leather. While a peeling device can be used for automatic peeling, it exerts external force on the paper, preventing the rear winding shaft from winding the paper. The original design of the machine ensures the rear winding shaft is loosely connected to the paper, allowing winding only when the paper feed roller delivers the paper; otherwise, the winding shaft spins freely inside the paper tube. If the paper is tightly wound, the force from the winding shaft disrupts the force provided by the paper feed roller, reducing the forward travel distance and resulting in defective products. Utility Model Content

[0003] To solve the above problems, this utility model provides a leather peeling device for a leather punching machine.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a leather peeling device for a leather punching machine, including a machine frame with a coupler controller, a coupler bracket, a paper winding shaft motor, and a paper support shaft. The coupler bracket is equipped with a coupler and a motor shaft. The two ends of the coupler are fitted with sprocket one and sprocket two. The two ends of the motor shaft are fitted with sprocket six and sprocket three. Chain two connects sprocket two and sprocket three. The paper winding shaft drive shaft is connected to sprocket four. Chain one connects sprocket four and sprocket one. The paper winding shaft motor is connected to sprocket five. Chain three connects sprocket five and sprocket six. The paper support shaft, fixed bracket two, and fixed bracket one are connected in sequence. A peeling knife is installed on fixed bracket one.

[0005] Furthermore, the motor shaft is mounted on the coupler bracket via bearings and bearing housings.

[0006] Furthermore, a paper winding shaft drive shaft is installed on the equipment frame, and the paper winding shaft drive shaft is connected to the paper winding shaft via a paper winding shaft pin.

[0007] Furthermore, a paper feed motor is installed on the equipment frame, and the paper feed motor is connected to the lower feed roller.

[0008] Furthermore, the paper support shaft is connected to the second fixed bracket by a fixing pin.

[0009] Furthermore, the second fixed bracket is fixed to one end of the shaft of the first fixed bracket, and the spring is fitted on the shaft of the first fixed bracket. One end of the spring is fixed to the second fixed bracket, and the other end is fixed to the first fixed bracket.

[0010] This invention can automatically peel off leather items stuck to perforated paper and collect them via a conveyor belt, achieving the effect of reducing manpower and increasing efficiency. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be further described below.

[0018] The leather peeling device of the leather punching machine includes a machine frame 1 equipped with a coupler controller 4, a coupler bracket 13, a paper winding shaft motor 15, and a paper support shaft 22. A paper feed motor 16 is mounted on the machine frame 1 and connected to the lower feed roller 3. A paper winding shaft drive shaft 7 is mounted on the machine frame 1 and connected to the paper winding shaft 5 via a paper winding shaft pin 6. A coupler 10 and a motor shaft 29 are mounted on the coupler bracket 13. The motor shaft 29 is mounted on the coupler bracket 13 via bearings 28 and bearing seats. Sprockets 1-8 and 12-12 are fitted at both ends of the coupler 10. Sprockets 6-30 and 14-14 are fitted at both ends of the motor shaft 29. Chain 211 connects sprocket 12 to sprocket 314; the paper winding shaft drive shaft 7 is connected to sprocket 424; chain 19 connects sprocket 424 to sprocket 18; the paper winding shaft motor 15 is connected to sprocket 525; chain 326 connects sprocket 525 to sprocket 630; the paper support shaft 22, the fixed bracket 21, and the fixed bracket 18 are connected in sequence; a peeling knife 17 is installed on the fixed bracket 18; the paper support shaft 22 is connected to the fixed bracket 21 by a fixing pin 27; the fixed bracket 21 is fixed to one end of the fixed bracket 1 shaft 20; a spring 19 is fitted on the fixed bracket 1 shaft 20; one end of the spring 19 is fixed to the fixed bracket 21, and the other end is fixed to the fixed bracket 18.

[0019] The perforated paper 23 is inserted between the upper forward roller 2 and the lower forward roller 3, then passes through the paper support shaft 22 and the peeling knife 17, and is wound onto the paper winding shaft 5. The paper winding shaft 5 is then powered by the coupler 10 to wind the perforated paper 23, tightening it, and then the peeling knife 17 peels off the adhered leather parts. Here, the coupler 10 needs to be adjusted by the coupler controller 4 to ensure that the force is less than the force given to the perforated paper 23 by the upper forward roller 2 and the lower forward roller 3. When the upper forward roller 2 and the lower forward roller 3 are not operating, and the coupler 10 slips and idles, the paper winding shaft 5 will not run. When the upper forward roller 2 and the lower forward roller 3 are operating, and there is excess perforated paper 23, the paper winding shaft 5 will run. This is to prevent the paper winding shaft 5 from affecting the pitch and causing product defects.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
