Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat cover processing equipment, in particular to a seat cover punching device. Background Art

[0002] Car seat covers are protective devices used to cover the surface of car seats. Car seat covers are made of a variety of materials, including fabric and leather. Leather seat covers, in particular, can cause stuffiness and even sweating when the air conditioner is on due to the contact between the back and buttocks and the non-breathable leather seat covers. Therefore, drilling small holes in the seat to increase breathability is bound to improve ride comfort.

[0003] A search revealed patent document CN218202885U, which discloses a device for punching holes in automobile seat covers. The device comprises a support frame, equipped with a transverse movement mechanism, a longitudinal movement mechanism, a punching mechanism, a backing plate, a locking nut, and a control mechanism. The longitudinal movement mechanism drives the transverse movement mechanism, which in turn drives the punching mechanism. The backing plate is located below the punching mechanism and fixed to the support frame at one end. A screw is connected to the other end of the backing plate. A support rod is rotatably connected to the support frame. The support rod and locking nut work in conjunction with the screw. The bottom of the backing plate is hollow, and the control mechanism controls the transverse movement mechanism, the longitudinal movement mechanism, and the punching mechanism. Advantages: The device achieves high punching efficiency, enabling non-destructive punching without disassembling the seat cover.

[0004] Although the above patent solution solves the shortcomings of traditional punching devices for automobile seat covers, the solution still has some shortcomings. Since the seat cover can be punched without disassembling the seat cover, the seam lines need to be avoided. The existing pattern is formed by laser cross calibration, and the seat cover needs to be centered during the calibration process. Therefore, the seat cover needs to be re-fixed and manually adjusted repeatedly to facilitate laser cross calibration. At the same time, during the punching process, debris is easily accumulated on the seat cover, which is difficult to clean later and affects the punching process. Therefore, we propose a seat cover punching device to solve the above problems. Utility Model Content
