DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] See also Figure 1A car seat leather cutting structure includes a first bracket 1, the bottom of the first bracket 1 is fixedly connected to the top of a first base plate 11, the top of the first base plate 11 is fixedly connected to a first base 20, the top of the first base 20 is fixedly connected to the bottom of a working platform 21, the top of the working platform 21 is fixedly connected to the bottom of a second L-shaped bracket 22, and the mutual cooperation between the first bracket 1, the first base plate 11, and the first base 20 can ensure the stability of the cutting device during operation to a great extent.

[0025] See also Figure 4 The top of the second L-shaped bracket 22 is fixedly connected to one side of the special-shaped plate 23. The setting of the special-shaped plate 23 can effectively provide support for the rear components. The middle part of the first base 20 is slidably connected to the outer circumferential surface of the first linkage column 24. The bottom of the first linkage column 24 is fixedly connected to the top of the pressing plate 25. The setting of the first linkage column 24 can effectively ensure the stability of the pressing plate 25 and avoid uneven force when fixing the leather, thereby affecting the subsequent leveling work.

[0026] See also Figure 1 and Figure 4 The top of the pressing plate 25 is fixedly connected to one end of the third spring 26, and the other end of the third spring 26 is fixedly connected to the bottom of the special-shaped plate 23. The setting of the third spring 26, utilizing the elasticity of the third spring 26 itself, can effectively push the pressing plate 25 to move, so that the pressing plate 25 automatically moves downward. The top of the first linkage column 24 is fixedly connected to the bottom of the first handle 27. The setting of the first handle 27 is convenient for the staff to operate. The top of the first bottom plate 11 is fixedly connected with a cutting machine body 28. The cutting machine body 28 is a prior art and will not be described in detail.

[0027] See also Figure 1 , Figure 2 and Figure 3 The top of the first base plate 11 is fixedly connected to the bottom of the positioning bracket 12, and a positioning module 13 is fixedly connected to one side of the positioning bracket 12. The setting of the positioning module 13 provides an effective fulcrum for the movement of subsequent components, thereby ensuring movement along a predetermined route. One side of the first bracket 1 is fixedly connected to one side of the circular support plate 2, and the other side of the circular support plate 2 is rotatably connected to the groove on one side of the first roller 3. The setting of the circular support plate 2 can ensure that the first roller 3 rotates in place under the action of the circular support plate 2 and is not prone to falling off.

[0028] See also Figure 3 and Figure 5The groove on the outer circumferential surface of the first roller 3 is fixedly connected to one end of the first track 14, and the other end of the first track 14 is fixedly connected to one side of the first shift plate 15. The setting of the first track 14 can effectively pull the first shift plate 15 to move when the first roller 3 rotates. One end of the first shift plate 15 is slidably connected to the groove on one side of the inner wall of the protective shell 16. The first shift plate 15 is an integral structure, which includes an external cylinder and a smooth cross plate. When the first shift plate 15 moves, it can ensure that the cross plate contacts the leather surface, thereby smoothing the wrinkles on the leather surface.

[0029] See also Figure 5 A limiting central axis 17 is fixedly connected to the middle of the protective shell 16. There are two groups of limiting central axis 17. The outer circumferential surfaces of the two groups of limiting central axis 17 are slidably connected to the middle of the first movable plate 15. The outer circumferential surfaces of the two groups of limiting central axis 17 are sleeved with second springs 18. The purpose of setting multiple groups of limiting central axis 17 is to make the first movable plate 15 more stable and less likely to tilt. At the same time, the setting of the second spring 18 can effectively and quickly reset the first movable plate 15.

[0030] See also Figure 1 and Figure 2 One side of the protective shell 16 is fixedly connected to one end of the first L-shaped bracket 19, the other end of the first L-shaped bracket 19 is fixedly connected to the top of the first base plate 11, and the other side of the first roller 3 is fixedly connected to the first limiting column 4, the outer circumferential surface of the first limiting column 4 contacts the bottom of the power single rod 5, the middle part of one end of the power single rod 5 is fixedly connected to the outer circumferential surface of the linkage single rod 6, and the other end of the linkage single rod 6 is rotatably connected to one side of the limiting disk 7. The first limiting column 4 is set, and when the power single rod 5 rotates, the first roller 3 will rotate synchronously under the action of the first limiting column 4.

[0031] See also Figure 2 The other side of the limiting disc 7 is fixedly connected to one end of the first spring 10, and the other end of the first spring 10 is fixedly connected to one side of the first bracket 1. The setting of the first spring 10, utilizing the elasticity of the first spring 10 itself, can effectively reset the limiting disc 7, and the other side of the limiting disc 7 is fixedly connected to one end of the guide single rod 8, and the outer circumferential surface of the guide single rod 8 is slidably connected to the inner wall of the first sleeve 9. The setting of the first sleeve 9 can effectively ensure the stability of the guide single rod 8 during movement, and the outer circumferential surface of the linkage single rod 6 is rotatably connected to the middle part of the first roller 3.

[0032] Working principle: Place the leather on the working platform 21. First, the third spring 26 will push the pressing plate 25 downward under the action of its own elasticity. The pressing plate 25 will contact the leather to fix the leather. Then, the linkage single rod 6 will rotate through external power, driving the power single rod 5 to rotate accordingly. When the power single rod 5 contacts the first limiting column 4, it will drive the first roller 3 on the first limiting column 4 to rotate accordingly. At this time, the first roller 3 rotates in place under the action of the circular support plate 2. The first roller 3 recovers the first crawler 14, which will pull the first moving plate 15 to slide in the protective shell 16. At this time, the second spring 18 is in a compressed state. When the power single rod 5 moves to the positioning module 13, the power single rod 5 will move according to the slope of the positioning module 13, pulling the limiting disc 7 on the linkage single rod 6 to slide in the circular support plate 2, and the guide single rod 8 slides in the first sleeve 9. At this time, the first spring 10 is in a stretched state. When the power single rod 5 completely passes through the positioning module 13, the first spring 10 itself resiliently resets the components. At the same time, the first shift plate 15 is reset under the action of the second spring 18, which can effectively flatten the wrinkled leather on the surface, thereby ensuring the accuracy of cutting.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
