Description

Technical Field

[0001] This application relates to the technical field of leather hot pressing, and in particular to a leather bonding hot pressing machine. Background Technology

[0002] In the leather goods manufacturing industry, bonding and hot pressing machines are key equipment for bonding and shaping leather materials (such as fabric and lining, multi-layered fabrics, etc.). They are mainly used to bond and shape leather with linings, reinforcements and other auxiliary materials through hot pressing. The performance of such equipment directly determines the bonding strength, flatness and overall appearance quality of leather products. Through the synergistic effect of heating and pressure, the adhesives (such as hot melt adhesives, glues, etc.) between leather materials are cured quickly, while ensuring that the bonded surface is flat and firm, which directly affects the appearance quality and service life of leather products.

[0003] Currently, the widely used traditional hot press machines, especially the basic models designed for small and medium-sized workshops or production line workstations, generally adopt a single-layer hot press platform design. This means that after completing one hot press operation, it is necessary to wait for the equipment to be turned on, the operator to unload the completed workpiece, and then put in a new workpiece to be processed and turn off the equipment before the next work cycle can begin. During the entire work cycle, the hot press mechanism is idle during loading and unloading, resulting in a waste of equipment utilization. Utility Model Content

[0004] The purpose of this application is to provide a leather bonding and hot pressing machine, which solves the problem that after a single-layer hot pressing platform completes one hot pressing operation, the operator needs to stop the machine to load and unload the workpiece before it can be hot pressed again, resulting in low equipment utilization, poor production continuity, and difficulty in meeting the needs of mass production.

[0005] The leather bonding and pressing machine provided in this application adopts the following technical solution: it includes a machine body, two support plates are fixedly connected to the inner walls of each of the two sides of the machine body, a slide rail is fixedly connected to one side surface of the support plate, a movable plate is slidably connected to the outer side of the slide rail, a lower support plate is fixedly connected between the two movable plates, a pull plate is fixedly connected to the end of the lower support plate away from the machine body, the pull plate is fixedly connected to the movable plate, a positioning plate is fixedly connected to the end of the lower support plate away from the pull plate, the positioning plate is fixedly connected to the movable plate, an upper support plate is hinged between the two movable plates, a groove is opened on the upper surface of the lower support plate and a lower cover plate is fixedly connected thereto, and a through hole is opened inside the upper support plate and an upper cover plate is fixedly connected thereto. By adopting the above technical solution, when using this device, the operator can place the leather goods to be hot-pressed on one of the lower support plates and push them into the machine body to complete the hot-pressing. At the same time, while the leather goods are being hot-pressed, the operator can simultaneously complete the clamping of the next batch of leather goods on another idle lower support plate. After the first leather goods are hot-pressed, it is only necessary to pull out the first hot-pressed leather goods and push in the clamped next batch of leather goods to achieve continuous hot-pressing operation, which greatly shortens the idle time of the equipment. This solves the problem that after a single-layer hot-pressing platform completes a hot-pressing operation, the operator needs to stop the machine to load and unload the workpiece before it can be hot-pressed again, resulting in low equipment utilization, poor production continuity, and difficulty in meeting the needs of mass production.

[0006] Preferably, an electric push rod is installed inside the machine body, and a hot pressing plate is installed on the output shaft of the electric push rod; By adopting the above technical solution, the electric push rod drives the hot pressing plate to move, which can accurately control the hot pressing pressure and height, adapt to the hot pressing needs of leather goods of different thicknesses, and the automated drive reduces the intensity of manual operation and improves the accuracy and consistency of hot pressing.

[0007] Preferably, both the lower cover plate and the upper cover plate are made of Teflon-coated fabric; By adopting the above technical solution, the lower and upper cover plates made of Teflon-coated fabric have high temperature resistance and anti-stick properties, which prevents leather goods from sticking to the cover plates during the hot pressing process, protects the surface quality of the leather goods, and extends the service life of the cover plates.

[0008] Preferably, a first magnet is fixedly connected to the lower surface of the upper support plate, and a second magnet is fixedly connected to the upper surface of the upper support plate. The first magnet is magnetically connected to the lower support plate, and the second magnet is magnetically connected to the machine body. A handle is fixedly connected to one end of the upper support plate, and a handle is fixedly connected to the side of the pull plate away from the moving plate. By adopting the above technical solution, the first magnet is magnetically fixed to the lower support plate, ensuring that the upper support plate is tightly attached to the lower support plate when closed. The second magnet is magnetically attached to the body, which can limit the position of the upper support plate after the upper and lower support plates are separated.

[0009] Preferably, two fixing brackets are fixedly connected to one side surface of the machine body, and a cylinder is fixedly connected to the upper surface of the fixing brackets; By adopting the above technical solution, the mounting bracket provides a stable installation base for the cylinder.

[0010] Preferably, the movable rod of the cylinder is fixedly connected to a limiting block, wherein the interior of the two support plates is provided with limiting holes that are adapted to the limiting block; By adopting the above technical solution, the cylinder drives the limit block to insert into the limit hole, which can quickly lock the position of the moving plate and the lower support plate, avoid the lower support plate from shifting due to vibration during hot pressing, and ensure the accuracy of the hot pressing position.

[0011] Preferably, the positioning plate has two stops on the side away from the lower support plate, the stops are fixedly connected to the inner wall of one side of the machine body, and two pressure sensors are fixedly connected to the inner wall of one side of the machine body; By adopting the above technical solution, the stop block forms a mechanical limit on the positioning plate, and in conjunction with the pressure sensor, it can accurately sense the state of the lower support plate being pushed into place, providing a signal for the subsequent hot pressing position.

[0012] Preferably, a switch button is fixedly connected to one side surface of the pull plate, and the switch button is electrically connected to the control circuit of the cylinder through a wire; By adopting the above technical solution, the switch button can control the control circuit of the cylinder, and the operator can conveniently control the extension and retraction of the limit block at the pull plate without the need for additional operation of other control components, simplifying the operation process and improving work efficiency.

[0013] In summary, this application includes at least one of the following beneficial technical effects: 1. This leather bonding and pressing machine, through the arrangement of a support plate, slide rail, moving plate, lower support plate, upper support plate, lower cover plate, and upper cover plate, allows the operator to place the leather to be pressed on one of the lower support plates and push it into the machine body for pressing. Simultaneously, while the leather is being pressed, the operator can clamp the next batch of leather on another idle lower support plate. After the first leather is pressed, simply pull out the first pressed leather and push in the clamped next batch of leather to achieve continuous pressing operations, greatly shortening the equipment's idle time. This solves the problem that single-layer pressing platforms require operators to stop the machine to load and unload workpieces after completing one pressing operation before pressing can be performed again, resulting in low equipment utilization, poor production continuity, and difficulty in meeting the needs of mass production.

[0014] 2. This leather bonding and pressing machine, through the configuration of an electric push rod, a pressing plate, a positioning plate, a cylinder, a limit block, a limit hole, a pressure sensor, and a switch button, allows the device to automatically position the height of the leather to be pressed by simply pushing the leather to be pressed into the machine body so that the positioning plate contacts the pressure sensor. The electric push rod then automatically moves the pressing plate to the appropriate height to press the leather. The switch button controls the cylinder, causing the limit block to enter the limit hole and contact the moving plate, thereby limiting the position of the lower support plate. This design eliminates the need for complex multi-stage transmission mechanisms and control systems, significantly reducing equipment manufacturing costs, failure probability, and maintenance difficulty while ensuring positioning accuracy and ease of operation, making it more suitable for the actual needs of small and medium-sized production enterprises.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0018] Example 1: A leather bonding and pressing machine, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4The system includes a body 1. Two support plates 4 are fixedly connected to the inner walls of each of its two sides. A slide rail 5 is fixedly connected to one side surface of each support plate 4. A movable plate 6 is slidably connected to the outer side of the slide rail 5. A lower support plate 7 is fixedly connected between the two movable plates 6. A pull plate 8 is fixedly connected to the end of the lower support plate 7 away from the body 1, and the pull plate 8 is fixedly connected to the movable plate 6. A positioning plate 9 is fixedly connected to the end of the lower support plate 7 away from the pull plate 8, and the positioning plate 9 is fixedly connected to the movable plate 6. An upper support plate 10 is hinged between the two movable plates 6. A groove is formed on the upper surface of the lower support plate 7, and a lower cover plate 11 is fixedly connected thereto. A through hole is formed inside the upper support plate 10, and an upper cover plate 12 is fixedly connected thereto. Both the lower cover plate 11 and the upper cover plate 12 are made of Teflon-coated fabric. A first magnet 13 is fixedly connected to the lower surface of the upper support plate 10, and a second magnet 14 is fixedly connected to the upper surface of the upper support plate 10. The first magnet 13 magnetically connects to the lower support plate 7, and the second magnet 14... 4. The machine body 1 is magnetically connected. One end of the upper support plate 10 is fixedly connected to a handle. The pull plate 8 is fixedly connected to a handle on the side away from the moving plate 6. Through the arrangement of the support plate 4, slide rail 5, moving plate 6, lower support plate 7, upper support plate 10, lower cover plate 11 and upper cover plate 12, when the device is in use, the operator can place the leather goods to be heated on one of the lower support plates 7 and push it into the machine body 1 to complete the heating. At the same time, while the leather goods are being heated, the operator can simultaneously complete the clamping of the next batch of leather goods on another idle lower support plate 7. After the first leather goods are heated, it is only necessary to pull out the first heated leather goods and push in the clamped next batch of leather goods to realize continuous heating operation, which greatly shortens the idle time of the equipment. It solves the problem that after a single-layer heating platform completes a heating operation, the operator needs to stop the machine to load and unload the workpiece before it can be heated again, resulting in low equipment utilization, poor production continuity and difficulty in meeting the needs of mass production.

[0019] Example 2: A leather bonding and pressing machine, referring to... Figure 3 , Figure 4 , Figure 5An electric push rod 2 is installed inside the machine body 1. A hot pressing plate 3 is installed on the output shaft of the electric push rod 2. Two fixed brackets 15 are fixedly connected to one side surface of the machine body 1. A cylinder 16 is fixedly connected to the upper surface of the fixed brackets 15. A limit block 17 is fixedly connected to the movable rod of the cylinder 16. Limiting holes 18 that are adapted to the limit blocks 17 are opened inside the two support plates 4. Two stops 19 are provided on the side of the positioning plate 9 away from the lower support plate 7. The stops 19 are fixedly connected to the inner wall of one side of the machine body 1. Two pressure sensors 20 are fixedly connected to the inner wall of one side of the machine body 1. A switch button 21 is fixedly connected to one side surface of the pull plate 8. The switch button 21 is electrically connected to the control circuit of the cylinder 16 through a wire. The connection is made through the electric push rod 2, the hot pressing plate 3, the positioning plate 9, and the cylinder 16. The inclusion of a limiting block 17, a limiting hole 18, a pressure sensor 20, and a switch button 21 allows the device to automatically position itself at a suitable height when the leather item to be heated is pushed into the machine body 1 so that the positioning plate 9 contacts the pressure sensor 20. This allows the electric push rod 2 to automatically move the heating plate 3 to the appropriate height for heating the leather item. The switch button 21 controls the cylinder 16, causing the limiting block 17 to enter the limiting hole 18 and contact the moving plate 6, thereby limiting the position of the lower support plate 7. This design eliminates the need for complex multi-stage transmission mechanisms and control systems, significantly reducing equipment manufacturing costs, failure probability, and maintenance difficulty while ensuring positioning accuracy and ease of operation. It is more suitable for the actual needs of small and medium-sized production enterprises.

[0020] The implementation principle of this application embodiment is as follows: In use, the operator presses the switch button 21 on one of the pull plates 8, which controls the cylinder 16 through the wire. The piston rod of the cylinder 16 controls the movement of the limiting block 17. After the limiting block 17 moves, it disengages from the limiting hole 18 and cancels the limitation on the moving plate 6, thereby allowing the operator to pull one of the pull plates 8. After the pull plate 8 moves, the moving plate 6 slides along the slide rail 5 on the support plate 4, pulling out one of the lower support plates 7 from inside the machine body 1. After pulling it out, the operator flips open the upper support plate 10. At this time, the first magnet 13 separates from the magnetic attraction of the lower support plate 7, and then the second magnet 14 contacts the machine body 1, thereby fixing the position of the upper support plate 10. Then the operator places the leather goods to be heated on the lower cover plate 11 above the lower support plate 7. After placement, the upper support plate 10 is closed to fix the first magnet 13 to the lower support plate 7. After fixing, the operator pushes the pull plate 8. The lower support plate 7 is inserted into the machine body 1 until the positioning plate 9 contacts the stop block 19 and triggers the pressure sensor 20. At this time, the operator can press the switch button 21 again to make the corresponding cylinder 16 drive the limit block 17 to move and enter the interior of the limit hole 18 to contact the moving plate 6, thereby limiting the position of the moving plate 6. When one of the pressure sensors 20 senses the pressure of the positioning plate 9, the electric push rod 2 is activated and drives the hot pressing plate 3 to move down. Together with the upper cover plate 12 and the lower cover plate 11 in the upper support plate 10, the leather is heated and pressed. At the same time, the operator follows the above steps to operate the other lower support plate 7 to complete the clamping of the next batch of leather. After the first leather is pressed, the electric push rod 2 drives the hot pressing plate 3 to reset. The operator can take out the pressed leather according to the above steps, and push the other lower support plate 7 with the clamped leather into the machine body 1 to repeat the above process to achieve continuous hot pressing operation.
