Description

Technical Field

[0001] This utility model relates to the field of leather perforation technology, specifically to a leather perforation device for wear-resistant PU leather bags. Background Technology

[0002] Overlock machines are used in much the same way as sewing machines. When overlocking heels, users need to constantly change the position of the heel to overlock. This poses a significant safety hazard because the hand is close to the needle when the heel is moved by hand, and the high-speed needle can easily prick the hand.

[0003] A search revealed that patent application CN211645284U discloses a leather perforation device, including a machine body and a worktable mounted on the machine body. A controller is located on the left side of the machine body, and a motor is located on the right side of the machine body. A screw is connected to the motor shaft, and the screw is installed inside the machine body. A limiting rod is provided parallel above the screw, and a threaded tube is fitted onto the screw. This allows the debris after perforation to be sucked in, ensuring a clean processing environment.

[0004] However, due to the design of the punch head, the diameter of the holes for punching leather varies, making it inconvenient to punch holes of different diameters and reducing its practicality. In addition, the leather is prone to shifting during punching, which affects the punching effect and results in poor punching quality.

[0005] Therefore, we propose a leather perforation device for wear-resistant PU leather bags. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a leather perforation device for wear-resistant PU leather bags, solving the problems of low practicality and poor perforation effect of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a leather punching device for wear-resistant PU leather bags, including a processing base, four sets of oppositely positioned connecting columns are fixedly installed on the top surface of the processing base, a top plate is fixedly installed on the top of the connecting columns, and four sets of oppositely positioned support legs are fixedly installed on the bottom surface of the processing base.

[0008] The top surface of the processing base is provided with threaded grooves with opposite positions. An auxiliary block of the same specification is assembled in the threaded groove. The outer wall of the auxiliary block is equipped with a thread of the same specification. The top surface of the auxiliary block is provided with a drilling groove. A hydraulic telescopic rod with opposite positions is fixedly installed on the bottom surface of the top plate. A connecting plate is fixedly installed at the bottom end of the hydraulic telescopic rod. A motor is fixedly installed on the bottom surface of the connecting plate. A drilling rod of the same specification is assembled on the output end of the motor through a slot.

[0009] The bottom surface of the punching rod has a groove of a matching size, and the bottom surface of the punching rod is fixedly installed with evenly distributed serrations. The bottom surface of the top plate is fixedly installed with four sets of connecting rods in opposite positions. The bottom end of the connecting rod is fixedly installed with a fixing plate. The top surface of the fixing plate is fixedly installed with four sets of electric telescopic rods in opposite positions. The telescopic end of the electric telescopic rod is fixedly installed with a pressure plate of a matching size.

[0010] Preferably, the top surface of the fixing plate is provided with a through groove that matches the specifications of the connecting plate, so that the connecting plate and the motor can pass through the through groove.

[0011] Preferably, a vacuum cleaner is fixedly installed on the front side of the processing seat, and a vacuum tube of the same specification is fixedly installed on the output end of the vacuum cleaner, so as to facilitate the removal of leather debris on the processing seat.

[0012] Preferably, a controller is fixedly installed on the front side of the processing base, and control buttons are mounted on the top surface of the controller, which facilitates the control of each component.

[0013] Preferably, the top surface of the auxiliary block is provided with a hexagonal groove, which facilitates the installation of the auxiliary block on the machining base.

[0014] Preferably, the bottom surface of the pressure plate is fitted with a rubber layer, which can improve the stability of the pressure plate in fixing the leather.

[0015] This is a leather perforation device for wear-resistant PU leather bags. By setting up auxiliary blocks, perforation slots and perforation rods, the device can change the perforation slots of different diameters according to the required perforation diameter by changing the auxiliary blocks, and change the perforation rod of appropriate specifications by changing the slots. This allows it to process holes of various diameters and improves practicality.

[0016] Simultaneously, through the setup of saw teeth, electric telescopic rod, and pressure plate, the electric telescopic rod drives the pressure plate to move downward, thereby compacting the area around the perforation in the leather to ensure the stability of the leather. Then, the motor drives the perforation rod to rotate, and the saw teeth cut and perforate the leather, improving the perforation effect. Attached Figure Description
