Description

Technical Field

[0001] The present invention relates to the technical field of seat leather processing equipment, in particular to a simple punching machine. Background Art

[0002] A leather punch is a mechanical device specifically designed for punching holes in leather or other leather materials. It typically consists of a punch head, a control system, and a workbench. It improves production efficiency, reduces labor costs, and ensures accurate and consistent punching. It also reduces damage and waste to the leather.

[0003] The prior art, such as the invention patent with authorization publication number CN102601821B and titled "Punching Machine Suitable for Cloth, Leather and Hide Materials," includes a frame having a working space, a punching knife assembly fixed in the working space, a punching plate that moves up and down in the working space, and a driving mechanism that drives the punching plate to move up and down. The lower end of the punching knife assembly has a detachable punching knife, the end of which is flat, and the punching plate has a flat surface, which is arranged parallel to the plane of the end of the punching knife, and the area of the surface is larger than the area of the plane where the end of the punching knife is located.

[0004] Although this type of punching machine can effectively realize automatic punching, in the current assembly line processing technology, it is often necessary to adjust the spacing between the holes on the leather according to the process requirements, so that the spacing between some holes is close and the spacing between some holes is far. When using this type of equipment, the feed of the external assembly line is required for adjustment. However, adjusting the spacing by adjusting the feed of the assembly line in the assembly line will greatly affect the subsequent processing technology, and when punching on the assembly line, the leather cannot be fixed during punching, so that the punched holes may be offset. Although some fully automatic punching machines can adjust the feed, they actually occupy a large area and will greatly increase the cost of use. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a simple punching machine for solving the technical problems raised in the background art that the existing punching machine cannot conveniently adjust the distance between holes and cannot fix the fabric when punching.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A simple punching machine includes a base and a fixing frame, the fixing frame is fixedly installed on the base, a driving motor is provided on the fixing frame, a driving rod is fixedly provided on the output end of the driving motor, the other end of the driving rod slides horizontally through the fixing frame, and a rotating plate is fixedly provided on the end, a punching assembly with adjustable punching frequency is provided on the rotating plate, and a limiting assembly is provided on the fixing frame for fixing the leather material when the punching assembly punches holes.

[0008] Working principle:

[0009] The invention relates to a simple punching machine, which is mainly used for punching leather.

[0010] During installation, you only need to add this equipment directly to the process line for use. When in use, place the leather to be processed on the base and directly below the punching assembly. Then, use the punching drive motor to drive the drive motor to rotate the drive rod, and then drive the driving rod to rotate the rotating plate installed at the end, and the rotating rod further drives the punching assembly to perform up and down punching operations.

[0011] When punching holes, the punching assembly moves downward to punch holes, driving the limit assembly to move and positioning the leather material passing on the base for punching holes.

[0012] The beneficial effects obtained.

[0013] First, a punching component is provided, which can effectively punch holes in the leather passing through the base to achieve the required punching process.

[0014] Second, the punching assembly is adjustably mounted on the rotating plate, which can effectively increase the up and down swing stroke of the punching assembly by adjusting the eccentricity of the punching assembly on the rotating plate, thereby increasing the spacing between the punched holes and achieving the purpose of adjusting the punching spacing.

[0015] Third, a limiting component is provided, which can effectively drive the limiting component through the punching component to position the leather passing through the base, making subsequent punching more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] Example:

This arrangement can effectively drive the driving rod 4 to move through the rotation of the driving motor 3, and drive the rotating plate 6 at the end of the driving rod 4 to rotate, further causing the driving disc 7 installed on one side of the rotating plate 6 to rotate. At this time, the rotation of the driving disc 7 causes the slider 11 on the connecting rod 8 to slide in the arc-shaped slide 10 on the driving disc 7. By adjusting the eccentricity of the driving disc 7 on the rotating plate 6, the rotation amplitude of the driving disc 7 is increased, further driving the slider 11 to move in the slide 10. The connecting rod 8 moves up and down in the sliding hole 12, and the punch 9 installed at the bottom of the connecting rod 8 reciprocates to punch the leather material. A cutting groove 35 is provided at the bottom of the punch 9 to facilitate the punch 9 to punch the leather material. The bottom of the cutting groove 35 is also provided with a protrusion 36. The protrusion 36 can effectively prevent the cut waste from being blocked in the cutting groove 35.

[0025] like Figure 2 As shown, an adjustment slot 13 is provided on the side of the rotating plate 6 facing away from the drive rod 4, and a screw rod 14 is provided on the rotating plate 6. One end of the screw rod 14 passes through the side wall of the rotating plate 6 and extends into the adjustment slot 13, and is rotatably connected to the side wall of the adjustment slot 13. The screw rod 14 is threadedly connected to an adjustment block 15, and the adjustment block 15 slides against the side wall of the adjustment slot 13. One side of the adjustment block 15 is fixedly connected to one side of the drive disk 7 on the rotating plate 6. This arrangement can effectively drive the adjustment block 15 to move by rotating the screw rod 14, and move the drive disk 7 fixedly connected to the adjustment block 15 on the rotating plate 6. The section of the screw rod 14 that passes through the side wall of the adjustment slot 13 is a bare rod section without threads. This arrangement can ensure that the screw rod 14 rotates normally relative to the side wall of the adjustment slot 13, ensuring that the operation can be carried out normally.

[0026] like Figure 1 and Figure 3As shown, the fixing frame 2 is provided with a limiting component for fixing the leather material when the punching component punches holes. The limiting assembly includes a limiting plate 16, several first rotating shafts 17, several limiting blocks 18 and several sliding blocks 19. The limiting plate 16 is located below the fixed frame 2, and a through hole is opened on the limiting plate 16 for only the punching punch 9 to pass through. The top of the limiting plate 16 is fixedly provided with several springs 37, and the other ends of several springs 37 are fixedly connected to the bottom of the fixed frame 2. The side wall of the limiting plate 16 is provided with several openings 21, and several first rotating shafts 17 are installed in the openings 21 in a one-to-one correspondence and horizontal rotation. Several limiting blocks 18 are fixedly installed on the side walls of the first rotating shafts 17 in a one-to-one correspondence, and several second rotating shafts 20 are rotatably provided at the bottom of several limiting blocks 18. Several sliding blocks 19 are fixedly installed on the bottoms of several second rotating shafts 20 in a one-to-one correspondence. Several first rotating shafts 17 are all sleeved with torsion springs 22, and one end of several torsion springs 22 is fixedly connected to the side wall of the corresponding opening 21, and the other end is fixedly connected to the corresponding first rotating shaft 17. This arrangement allows the connecting rod 8 to abut against the top of the limit plate 16 when it moves downward, and drive the limit plate 16 to move downward together. When the sliding block 19 at the bottom of the limit plate 16 abuts against the leather material on the base 1, it will slide through the rotation of the first rotating shaft 17, and the leather material will be positioned by the elastic force of the torsion spring 22. A number of positioning pins 33 are provided at the bottom of the fixing frame 2, and a number of positioning holes 34 are also provided on the limit plate 16. One end of a number of the positioning pins 33 slides into the number of positioning holes 34 in a one-to-one corresponding manner. A sensing device 23 is provided at the bottom of the sliders 11. The sensing device 23 is electrically connected to the external assembly line master control device. When the sensing device 23 abuts against the leather material, the assembly line will automatically stop running, facilitating the punching assembly to perform the punching operation on the leather material. The sensing device 23 is a common device in the prior art of this field, and the present application will not elaborate on its specific structure.

[0027] like Figure 1As shown, a ventilation slot 24 is defined within the base 1. An inverted conical waste hole 25 is defined on the base 1 and directly below the punching assembly. The waste hole 25 is connected to the ventilation slot 24. A blowing assembly is defined within the ventilation slot 24. The blowing assembly comprises a blowing rod 26, a blowing blade 27, a first pulley 28, a second pulley 29, and a belt 30. The blowing rod 26 is horizontally and rotatably mounted on the bottom of the ventilation slot 24. The blowing blade 27 is fixedly mounted on the end of the blowing rod 26. The first pulley 28 is fixedly sleeved on the side wall of the driving rod 4. The second pulley 29 is fixedly sleeved on the side wall of the blowing rod 26. A connecting hole 31 is defined on the fixing frame 2 that is connected to the ventilation slot 24. The belt 30 is sleeved between the first pulley 28 and the second pulley 29 through the connecting hole 31. The diameter of the first pulley 28 is larger than that of the second pulley 29. This allows the belt 30 to rotate the second pulley 29 multiple times for every one rotation of the first pulley 28. A collection bag 32 is fixed to the notch of the ventilation slot 24. A dust cover 5 also covers the top of the fixed frame 2. This dust cover 5 prevents foreign matter from entering and interfering with the driving disc 7 and the driving rod 8 to perform drilling.

[0028] Working principle:

[0029] During installation, the punching machine is installed on the production line, and the sensing device 23 is electrically connected to the driving master control device of the production line. After the installation is completed, the punching machine can be used.

[0030] When in use, the leather material to be processed is placed on the base 1 and is located directly below the punching punch 9. The rotation of the driving motor 3 drives the driving rod 4 to move, and drives the rotating plate 6 at the end of the driving rod 4 to rotate, and further rotates the driving disk 7 installed on one side of the rotating plate 6. At this time, the rotation of the driving disk 7 will cause the slider 11 on the connecting rod 8 to slide in the arc-shaped slide groove 10 on the driving disk 7. By adjusting the eccentricity of the driving disk 7 on the rotating plate 6, the rotation amplitude of the driving disk 7 is increased, and the progress of the slider 11 in the slide groove 10 is further increased, so that the connecting rod 8 reciprocates up and down in the sliding hole 12, and the punch installed at the bottom of the connecting rod 8 The punch 9 punches the leather material reciprocatingly. When punching, it moves downward through the connecting rod 8 to abut against the top of the limit plate 16, and drives the limit plate 16 to move downward together. When the sliding block 19 at the bottom of the limit plate 16 abuts against the leather material on the base 1, it will slide through the rotation of the first rotating shaft 17, and the leather material will be positioned by the elastic force of the torsion spring 22. Finally, the waste produced by punching will enter the ventilation slot 24 through the waste hole 25 on the base 1, and then the second pulley 29 and the blowing rod 26 are driven to rotate through the first pulley 28 and the belt 30, and further drive the blowing fan blades 27 at the end of the blowing rod 26 to rotate and blow, and blow the waste into the collection bag 32.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
