Description

Technical Field

[0001] This utility model relates to the field of leather processing equipment, and specifically provides a leather punching device with automatic replacement of padding paper. Background Technology

[0002] In the leather processing industry, punching is widely used in footwear, bags, automotive interiors, furniture, and clothing to improve the breathability and aesthetics of leather. Punching equipment uses a controlled, up-and-down moving punch to punch holes in the leather material. A layer of paper of a certain thickness needs to be placed under the leather to prevent damage from the punch colliding with the work platform after penetrating the leather. However, in traditional punching techniques, one piece of leather corresponds to one piece of paper. After a piece of leather is punched and removed from the equipment, not only must a new piece of leather be replaced, but the paper must also be replaced and aligned with the leather before punching can continue. This cumbersome operation significantly reduces the punching efficiency of the equipment. Utility Model Content

[0003] Firstly, to address the aforementioned problems, this utility model provides a leather punching device capable of automatically replacing the backing paper. After punching a piece of leather, only the leather needs to be removed and a new piece inserted; the punching device can automatically replace the backing paper, thus improving the working efficiency of the leather punching equipment. The specific technical solution is as follows:

[0004] An automatic leather punching device for changing padding paper includes a frame and punching cutters mounted on the frame, as well as a paper roll. A working platform is mounted on the frame. The paper roll on the working platform includes a feeding paper roll and a receiving paper roll, which are respectively mounted at both ends of the frame. Padding paper is output from the feeding paper roll and laid on the working platform. The receiving paper roll is used to collect the padding paper on the working platform.

[0005] In this solution, it is not necessary to match leather and padding paper one by one as in the traditional method. By setting up a paper roll, after the padding paper output by the paper roll is used up, the paper roll rotates to continue outputting padding paper. The used part of the padding paper moves out of the working position of the working platform, and the new unpunched padding paper moves to the working position of the working platform and rotates to replace the padding paper. There is no need for cumbersome operations, which greatly saves the time of padding paper replacement and effectively improves the punching efficiency of the punching equipment.

[0006] Preferably, the frame includes opposing support plates, which are vertically arranged on both sides of the work platform, and the pivots at both ends of the paper roll are respectively mounted on the support plates. The entire frame consists of two support plates and a work plate, resulting in a simple structure that is lighter and easier to maintain and repair than a cabinet-type punching machine.

[0007] Preferably, the support plates are symmetrically arranged, and a crossbeam is also provided between the support plates. The crossbeam is located above the working platform, and the crossbeam and the support plates form a transverse gantry frame. The punching cutter is slidably mounted on the gantry frame via a tool holder, and the punching cutter can move on the crossbeam.

[0008] In this design, the support plate is an important component supporting the entire equipment. Almost all the equipment is set between two support plates, which makes it easier to install and disassemble the equipment. At the same time, as long as the strength and quality of the support plate are guaranteed, the overall strength of the punching equipment can be guaranteed. Furthermore, the punching knife moves on the crossbeam to punch large areas of leather, while the crossbeam also plays a role in strengthening the frame.

[0009] Preferably, the paper roll includes a feeding paper roll and a receiving paper roll, which are respectively disposed at both ends of the frame. The padding paper is output from the feeding paper roll and recycled into the receiving paper roll. The padding paper is conveyed longitudinally along the working platform.

[0010] In this scheme, the feeding paper roll rotates to feed materials while the receiving paper roll rotates to collect materials, ensuring the continuity of the padding paper replacement on the work platform. At the same time, there is no need to manually collect the used padding paper, as it is automatically collected in the receiving paper roll. Similarly, when the padding paper on the feeding paper roll is used up, only the feeding paper roll needs to be replaced, which greatly simplifies the operation for workers and improves the ease of use of the equipment.

[0011] Preferably, a slide rail is provided on the support plate along the conveying direction of the padding paper. The slide rail is located above the working platform. A leather placement frame is slidably arranged along the slide rail. The leather placement frame is in contact with the padding paper and can slide back and forth along the slide rail.

[0012] In this solution, a leather placement frame is set up to provide a place for the leather, while also separating the leather from the padding paper. The automatic replacement of the padding paper is not affected when the leather is replaced.

[0013] Preferably, multiple reinforcing beams are connected between the support plates, and the working platform is positioned above the reinforcing beams.

[0014] Secondly, since the padding paper is driven by two paper rolls, in order to prevent the padding paper from being torn due to tension, a first rotating roller is provided at both ends of the working platform. The first rotating roller is driven by a first motor. The two ends of the padding paper on the working platform are connected to the corresponding paper rolls after passing around the first rotating rollers. The feeding paper roll and the receiving paper roll are both driven to rotate by a second rotating roller, which is driven by a second motor.

[0015] In this scheme, the paper roll rotates due to the rotation of the second rotating roller, thereby receiving and discharging the paper. However, the tension of the padding paper on the entire working platform is actually controlled by the first rotating roller. For the feeding paper roll, the second rotating roller can control the feeding paper roll to rotate and output the padding paper in advance. For the receiving paper roll, the second rotating roller can control the receiving paper roll to delay the winding of the padding paper, so that only the padding paper section above the working platform receives a certain tension, while the padding paper section between the paper roll and the first rotating roller can be in a relatively loose state, thereby reducing the possibility of the entire padding paper being torn.

[0016] Preferably, the support plate is provided with multiple connecting holes, through which the crossbeam, reinforcing beam, roller seat of the first rotating roller, and roller seat of the second rotating roller are bolted. Connecting the various components by providing connecting holes on the support plate facilitates the installation, disassembly, and replacement of each piece of equipment.

[0017] Preferably, the first motor and the second motor are disposed on the outside of the support plate, and a protective shell is also disposed on the outside of the support plate, and an inspection door is disposed on the surface of the protective shell.

[0018] Preferably, the frame is further provided with a controller module, which is used to control the punching action of the punching knife and the rotation of the feeding paper roll and the receiving paper roll, so as to realize the automatic replacement of the pad paper.

[0019] The beneficial effects of this utility model are as follows: Unlike the traditional method, this utility model does not require matching leather and padding paper one-to-one. By setting a paper roll, after the padding paper output by the paper roll is used up, the paper roll rotates to continue outputting padding paper. The used part of the padding paper moves out of the working position of the working platform, and the new unpunched padding paper moves to the working position of the working platform and rotates to realize the replacement of the padding paper. There is no need for cumbersome operations, which greatly saves the time of padding paper replacement and effectively improves the punching efficiency of the punching equipment.

Detailed Implementation

[0026] The technical solution of the present invention will be clearly and completely described in conjunction with the accompanying drawings and through specific implementation methods of the embodiments of the present invention.

[0027] Example 1:

[0028] A leather punching device that automatically replaces padding paper 31, such as Figures 1 to 3 As shown, the machine includes a frame 1 and a punching knife 2 mounted on the frame 1, as well as a paper roll 3. The frame 1 includes a working platform 11 and a support plate 12. The working platform 11 is preferably horizontally arranged, and the support plate 12 is symmetrically and vertically arranged on both sides of the working platform 11. The two ends of the paper roll 3 are mounted on the support plate 12, and the paper roll 3 outputs pad paper 31 onto the working platform 11.

[0029] Specifically, the working platform 11 is disposed between the support plates 12, and a crossbeam 4 is also disposed between the support plates 12. The crossbeam 4 is located above the working platform 11, and the crossbeam 4 and the support plates 12 form a transverse gantry frame. The punching cutter 2 is slidably disposed on the gantry frame via a cutter holder. A mutually compatible pulley and slide rail structure 13 can be provided between the cutter holder of the punching cutter 2 and the crossbeam 4, and the punching cutter 2 is driven by a motor to move on the crossbeam 4. At the same time, multiple reinforcing beams 5 are connected between the support plates 12, and the working platform 11 is disposed above the reinforcing beams 5. A slide rail 13 is disposed on the support plate 12 along the conveying direction of the padding paper 31. The slide rail 13 is located above the working platform, and a leather placement frame 14 is slidably disposed on the slide rail 13. The leather placement frame 14 contacts the padding paper 31. The leather placement frame 14 can also be provided with a power transmission structure, such as a drive roller, a screw and nut structure, etc., so that the leather placement frame 14 can slide back and forth along the slide rail 13. The leather placement frame 14 provides a storage location for the leather and separates it from the padding paper 31. Changing the leather does not affect the automatic replacement of the padding paper 31. The support plate 12 has multiple connection holes through which the crossbeam 4 and reinforcing beam 5 are bolted. The connection holes on the support plate 12 facilitate the installation, disassembly, and replacement of various components.

[0030] Furthermore, the paper roll 3 includes a feeding paper roll 32 and a receiving paper roll 33, which are respectively disposed at both ends of the frame 1. The padding paper 31 is output from the feeding paper roll 32 and recycled into the receiving paper roll 33. The padding paper 31 is conveyed longitudinally along the working platform 11. The feeding paper roll 32 rotates to feed the paper, while the receiving paper roll 33 rotates to collect the paper, ensuring the continuity of padding paper 31 replacement on the working platform 11. It also eliminates the need for manual collection of used padding paper 31, as it is automatically collected in the receiving paper roll 33. Similarly, when the padding paper 31 in the feeding paper roll 32 is used up, only the feeding paper roll 32 needs to be replaced, greatly simplifying the operation and improving the ease of use of the equipment.

[0031] In this embodiment, unlike the traditional method of matching leather and padding paper 31 one-to-one, by setting up paper roll 3, after the padding paper 31 output by paper roll 3 is used up, paper roll 3 rotates to continue outputting padding paper 31. The used part of padding paper 31 moves out of the working position of the working platform 11, and the new unpunched padding paper 31 moves to the working position of the working platform 11 and rotates to realize the replacement of padding paper 31. There is no need for cumbersome operations, which greatly saves the time of replacing padding paper 31 and effectively improves the punching efficiency of the punching equipment. At the same time, the entire frame 1 is composed of two support plates 12 and a working plate, which has a simple structure, is lighter than the cabinet structure punching equipment, and is easier to maintain and repair.

[0032] Example 2:

[0033] Since the padding paper 31 is driven by two paper rolls 3, in order to prevent the padding paper 31 from being torn due to tension, this embodiment, based on embodiment one, such as... Figure 2 As shown, the working platform 11 is provided with first rotating rollers 6 at both ends. The first rotating rollers 6 are driven by first motors 61. The pad paper 31 located on the working platform is connected to the corresponding paper roll 3 after passing around the transmission rollers at both ends. The feeding paper roll 32 and the receiving paper roll 33 are both driven to rotate by second rotating rollers 7. The second rotating rollers 7 are driven by second motors 71. The second rotating rollers 7 can be the rotating shaft of the paper roll 3, or they can be rollers arranged between the support plates 12 and always in contact with the paper roll 3. The second rotating rollers 7 are driven to rotate by the second motors 71, thereby causing the paper roll 3 to rotate.

[0034] The paper roll 3 rotates due to the rotation of the second rotating roller 7, thereby receiving and discharging the paper. However, the tension of the pad paper 31 on the entire working platform 11 is actually controlled by the first rotating roller 6. For the feeding paper roll 32, the second rotating roller 7 can control the feeding paper roll 32 to rotate and output the pad paper 31 in advance. For the receiving paper roll 33, the second rotating roller 7 can control the receiving paper roll 33 to delay the winding of the pad paper 31, so that only the pad paper 31 section above the working platform 11 receives a certain tension, while the pad paper 31 section between the paper roll 3 and the first rotating roller 6 can be in a relatively loose state, thereby reducing the possibility of the entire pad paper 31 being torn.

[0035] Furthermore, in order to ensure that the first rotating roller 6 has sufficient friction with the padding paper 31 and can drive the padding paper 31 to move around itself through its own rotation, the first rotating roller 6 is also equipped with an auxiliary rotating roller 8. The auxiliary rotating roller is also set between the support plates 12, and the distance between the auxiliary rotating roller 8 and the first rotating roller 6 is adjustable. The padding paper 31 passes around the auxiliary rotating roller 8 and the first rotating roller 6, and by adjusting the distance between the auxiliary rotating roller and the first rotating roller 6, the first rotating roller 6 and the auxiliary rotating roller clamp the padding paper 31, ensuring that the padding paper 31 will not slip at the first rotating roller 6 when the first rotating roller 6 rotates.

[0036] It should be noted that the roller shafts of the first rotating roller 6, the second rotating roller 7, and the auxiliary rotating roller 8 are all mounted on roller seats, which are bolted to the support plate 12. The first rotating roller 6 and the second rotating roller 7 are driven by motors, and one end of the roller shafts of the first rotating roller 6 and the second rotating roller 7 extends out of the support plate 12 on one side. The first motor 61 and the second motor 71 are both located on the outside of the support plate 12 and are connected to the extended roller shafts of the first rotating roller 6 and the second rotating roller 7 respectively via belt drive.

[0037] Furthermore, a protective shell 9 is provided on the outer side of the support plate 12. The surface of the protective shell 9 is provided with an inspection door 91. By opening the inspection door 91, the interior of the protective shell 9 can be exposed, which facilitates the inspection and maintenance of other equipment such as motors and controller modules.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
