AI Technical Summary
In existing technologies, leather is prone to wrinkles during the cutting process, which affects the cutting accuracy and makes it difficult to keep it flat.
The system uses L-shaped and C-shaped positioning components in conjunction with a pen-type electric push rod. Through the abutment of the upper and lower pressure plates, the horizontal movement of the drive block drives the positioning components to move, thus flattening the leather. At the same time, the positioning post is designed with telescopic airbag strips and abutment strips to adapt to I-beams of different inner diameters, ensuring fixation and limiting.
This effectively avoids the impact of wrinkles on cutting accuracy during leather cutting, improving the adaptability and cutting precision of the device.

[0031] The utility model will be further described in detail in combination with the drawings.
[0032] Please refer to Figures 1 to 9 The utility model provides a technical scheme: a cutting auxiliary device for leather production and processing, which comprises a mobile seat 1, a box 2, a workbench 3, an L-shaped positioning piece 11 and a U-shaped positioning piece 10, the upper end of the mobile seat 1 is fixedly connected with the box 2, the upper end of the box 2 is fixedly connected with the workbench 3, the rear side of the upper surface of the workbench 3 is fixedly connected with a column 4, the front end of the column 4 is fixedly connected with a positioning column 6 for fixing a spool 5, the outer part of the spool 5 is provided with leather cloth, one side of the column 4 is fixedly connected with a connecting rod 7, the end of the connecting rod 7 is rotatably connected with a rotating shaft 8 for pressing the leather cloth downward;
[0033] A strip-shaped groove for horizontal movement of the drive block 9 is provided on the rear side of the middle section of the housing 2 and the workbench 3. A U-shaped positioning component 10 is fixed to the upper end of the drive block 9. An L-shaped positioning component 11 is provided on one side of the U-shaped positioning component 10. The L-shaped positioning component 11 is fixed to the upper end of the workbench 3. Pen-type electric push rods 12 are fixed to the upper ends of both the L-shaped positioning component 11 and the U-shaped positioning component 10. The telescopic ends of the two pen-type electric push rods 12 pass through the middle of the L-shaped positioning component 11 and the U-shaped positioning component 10, respectively, and are fixed to the upper pressure plate 13. A lower pressure plate 14 is provided below each upper pressure plate 13, located at the U-shaped positioning component. The lower pressure plate 14 of the L-shaped positioning member 10 is fixed to the lower end of the middle part of the L-shaped positioning member 10. The lower pressure plate 14 of the L-shaped positioning member 11 is fixed to the upper end of the worktable 3. Considering that the leather needs to be stretched flat during the cutting process to avoid the problem that the leather itself has wrinkles that affect the cutting accuracy, this utility model uses the L-shaped positioning and the upper pressure plate 13 and lower pressure plate 14 in the middle of the L-shaped positioning member 10 to abut against the leather to be cut. Then, the driving block 9 moves horizontally to drive the L-shaped positioning member 10 to move so that the leather to be cut can be stretched flat, thereby avoiding the problem that the leather has wrinkles that affect the cutting accuracy during cutting.
[0034] Among them, guide rods 15 are fixed at the four corners of the upper end of the two upper pressure plates 13, and anti-slip pads 16 are fixed on the contact surfaces of each upper pressure plate 13 and lower pressure plate 14. The guide rods 15 guide the moving upper pressure plates 13, ensuring that the pressure plates move vertically. The presence of anti-slip pads 16 increases the friction between the upper pressure plates 13 and lower pressure plates 14 and the leather contact surfaces.

One end of the reciprocating screw 17 is rotatably connected to the inner wall of the housing 2 via a bearing, and the other end of the reciprocating screw 17 is fixed to the output shaft of the motor 18 via a coupling. The motor 18 is fixed inside the housing 2 via a mounting bracket. A threaded sleeve is installed on the outside of the reciprocating screw 17. The upper end of the threaded sleeve is fixed to the bottom of the drive block 9 via a screw, and the lower end of the threaded sleeve is fixed to the guide block 19. The guide block 19 has a clearance hole through the middle for the installation of the slide rod 20. The slide rod 20 is fixed inside the housing 2 via a support block 21. The motor 18 drives the reciprocating screw 17. During the rotation of the reciprocating screw 17, the threaded sleeve moves synchronously. At this time, the synchronous movement of the threaded sleeve is guided by the guide block 19 and the slide rod 20, so that the synchronous movement of the threaded sleeve becomes a horizontal reciprocating movement along the reciprocating screw 17.
[0036] The inside of the positioning column 6 is provided with three movable cavities for the extension and retraction of the abutting strips 22. The inside of each movable cavity is fixed with an extension and retraction air bag strip 23. The top of each extension and retraction air bag strip 23 is fixed with the inside of the abutting strip 22. The top of each abutting strip 22 is fixed with a sleeve block 24 installed T-shaped block 25. The side of each sleeve block 24 is installed with a spring latch 26. The pin head of the spring latch 26 penetrates the sleeve block 24 and abuts with the groove on the side of the T-shaped block 25. The outside of each sleeve block 24 is fixed with a rubber strip 27. The abutting strip 22 can be designed to extend and retract outside the positioning column 6, so that the positioning column 6 cooperates with the abutting strip 22 to fix the I-shaped wheel 5 with different inner diameter sizes, thereby improving the adaptation ability of the device. That is, after the I-shaped wheel 5 wrapped with leather is sleeved outside the positioning column 6, the extension and retraction air bag strip 23 can be inflated to push out the abutting strip 22, thereby abutting with the inner surface of the I-shaped wheel 5 to complete the limiting.
[0037] The front end of the positioning column 6 is provided with a gas pipe 28. The outside of the gas pipe 28 is connected with the gas nozzles of the three extension and retraction air bag strips 23 through three conduits 29. The side end of each conduit 29 is communicated with a control valve 30. The other end of the control valve 30 is provided with an exhaust pipe. The front end of the gas pipe 28 penetrates the box body 2 through an injection pipe 31 and is communicated with a small injection pump 32 inside the box body 2. The small injection pump 32 is arranged to inject gas into the injection pipe 31. After the gas is dispersed into the three conduits 29 through the injection pipe 31, it enters the inside of the extension and retraction air bag strip 23. When the I-shaped wheel 5 needs to be disassembled, the control valve is opened to open the exhaust end. At this time, the gas is discharged through the exhaust end.
[0038] The negative pressure end of the small injection pump 32 is communicated with a filter pipe 33 through a pipeline. The other end of the filter pipe 33 penetrates to the back of the box body 2. The inside of the filter pipe 33 is fixed with a placing ring 34 symmetrically. An air filter element 35 is arranged between the two placing rings 34. The middle part of each placing ring 34 is fixed with a gas permeable hole for installing a dustproof net 36. The air filter element 35 and the dustproof net 36 are arranged to filter the gas entering the small injection pump 32 and conveyed to the conduit 29, so as to prevent dust and particulate matter in the air from blocking the pipeline.
[0039] The both ends of the box body 2 are hinged with door plates 37. The back of each door plate 37 is fixed with a storage frame 38 for placing tools for workers. The inside of each storage frame 38 is provided with an adsorption pad 39. The inside of the adsorption pad 39 is provided with a magnetic strip 40 for adsorbing metal tools. The storage frame 38 is arranged to place the tools needed by the workers during the cutting process. The metal tools are further fixed by the adsorption pad 39.
