[0002] In the field of leather processing technology, the composite process of leather fabrics and linings is a key link in improving the quality and performance of leather products. By composite leather fabrics and linings, the strength, warmth retention, comfort, etc. of leather products can be enhanced, and the appearance of the products can be enriched. It is widely used in many fields such as clothing, luggage, home decoration, etc.
[0003] Due to the special nature of its material, traditional leather jackets usually adopt a single-layer design.

In recent years, the clothing manufacturing industry has gradually begun to study how to improve the thermal insulation performance of leather jackets while maintaining their original characteristics to meet consumers' demand for multifunctional clothing. Although the thermal insulation performance of leather jackets has been improved by adding lining and filling layers, the filling layers often have poor uniformity and stability, which can easily lead to local overheating or overcooling.

DETAILED DESCRIPTION
[0021] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a leather fabric and lining composite device, including a workbench 1, the lower surface of the workbench 1 is fixedly connected to a base 2, the upper surface of the base 2 is rotatably connected to a rotating column 3, the upper surface of the rotating column 3 is fixedly connected to a fixed column 4, the outer wall of the fixed column 4 is fixedly connected to a controller 5, a connecting rod 6 is provided inside the fixed column 4, the outer wall of the connecting rod 6 is rotatably connected to a mounting column 1 7, the outer wall of the mounting column 1 7 is fixedly connected to an extrusion assembly 8, a stamping plate 9 is provided at the bottom end of the mounting column 1 7, the outer wall of the extrusion assembly 8 is slidably connected to the inside of the stamping plate 9, and both sides of the upper surface of the stamping plate 9 are fixedly connected to a handle 2 10, a heating plate 11 is provided on the lower surface of the stamping plate 9, and the heating plate 11 and the controller 5 are electrically connected; a fixing assembly 13 is fixedly connected to the inside of the heating plate 11, and a mounting assembly 12 is fixedly connected to the lower surface of the stamping plate 9, the outer wall of the fixing assembly 13 is provided inside the mounting assembly 12, and the heating plate 11 is provided with hot pressing blocks of different shapes.
[0023] Specifically, when a composite operation is required, the operator first places the leather fabric and lining in the appropriate position on the workbench 1 as required. Then, the operator can hold the handles 2 10 on both sides of the upper surface of the stamping plate 9 and manually press the stamping plate 9 downward. The mounting column 1 7 and the connecting rod 6 are used to assist the stamping plate 9 in moving downward more stably. During the downward pressing process of the stamping plate 9, the heating plate 11 on its lower surface has reached a preset temperature under the control of the controller 5. The heating plate 11 contacts the leather fabric and the lining, and uses hot pressing to make the two fit together tightly to complete the composite operation. The connecting rod 6 is set inside the fixed column 4, and the fixed column 4 is used to support the connecting rod 6 to slide inside it.
[0024] The hot pressing blocks of different shapes on the heating plate 11 will press out corresponding patterns on the surface of the leather fabric. These patterns are not only decorative, but also can separate the internal space of the leather jacket when making leather jackets, which is conducive to the uniform distribution of filling thermal insulation materials such as down, thereby improving the performance and quality of the product. The stamping plate 9 is used to fix the installation component 12, and the installation component 12 and the fixing component 13 cooperate with each other to quickly install and remove the heating plate 11.
[0025] Please see the attached Figure 3 -Attached Figure 5The extrusion assembly 8 includes a connecting plate 81, the outer wall of the connecting plate 81 is fixedly connected to the outer wall of the mounting column 7, the inner wall of the connecting plate 81 is rotatably connected to a handle 83, and the inner wall below the handle 83 is rotatably connected to an extrusion rod 82, and the bottom end of the extrusion rod 82 is fixedly connected to the upper surface of the stamping plate 9.
[0026] Specifically, when the operator presses down the handle 83, since the handle 83 is rotatably connected to the connecting plate 81, and the inner wall of the lower side of the handle 83 is rotatably connected to the extrusion rod 82, the rotation of the handle 83 will drive the extrusion rod 82 to move, and the bottom end of the extrusion rod 82 is fixedly connected to the upper surface of the stamping plate 9. The movement of the extrusion rod 82 can push the stamping plate 9 to move downward, and the mounting column 7 plays a supporting and stabilizing role, ensuring that the relative positions of the various components of the extrusion assembly 8 are stable, so that the stamping plate 9 is pressed down smoothly. When the stamping plate 9 is pressed down to the appropriate position, the heating plate 11 on its lower surface will contact the leather fabric and lining placed on the workbench 1, and then the two are hot-pressed and composited. By pressing down the handle 83 to control the movement of the stamping plate 9, compared with directly manually pressing down the stamping plate 9, the operator can control the downward force and speed more conveniently and labor-savingly, thereby improving the accuracy and stability of the composite process and ensuring better composite of the leather fabric and the lining.
[0027] Please see the attached Figure 5 and attached Figure 7 The fixing component 13 includes a connecting block 131, the outer wall of the connecting block 131 is arranged inside the heating plate 11, the upper surface of the connecting block 131 is fixedly connected to a connecting column 132, and the upper inner wall of the connecting column 132 is fixedly connected to the mounting column 133; the fixing component 13 also includes a spring 134, the upper outer wall of the spring 134 is arranged on the lower inner wall of the connecting block 131, and the bottom end of the spring 134 is provided with a pad 135; the material of the pad 135 is rubber.
[0028] Specifically, the outer wall of the connecting block 131 is arranged inside the heating plate 11, ensuring that the heating plate 11 and the connecting block 131 will not be displaced relative to each other during the operation of the device. The lower surface of the connecting column 132 is fixedly connected to the upper surface of the connecting block 131, providing an installation position for the second mounting column 133. The second mounting column 133 is fixed to the upper inner wall of the connecting column 132 and can be docked with the interior of the mounting component 12. The heating plate 11 is installed as a whole on the lower surface of the stamping plate 9 through the fixing component 13, ensuring that the heating plate 11 has a stable installation foundation in the equipment for hot pressing and laminating operations of leather fabrics and linings.
[0029] When the heating plate 11 is pressed down during the hot pressing and compounding operation, a certain impact force will be generated. The spring 134 can play a buffering role. It will undergo elastic deformation when under pressure, absorb and disperse part of the impact force, and avoid the impact force being directly transmitted to the entire device structure, reducing damage to other components of the device and extending the service life of the device. At the same time, the pad 135 can increase the force area between the spring 134 and the contact object, so that the spring 134 can assist in fixing the leather fabric and lining. In addition, after the hot pressing and compounding operation is completed, when the heating plate 11 rises and resets, the spring 134 will restore the elastic deformation, assisting the heating plate 11 to return to its initial position better, ensuring the consistency and stability of each hot pressing operation. The rubber has excellent anti-slip performance. During operation, it can effectively prevent the pad 135 from sliding with the contacted parts, ensuring the relative position stability of the fixing component 13 and related components, and ensuring the accuracy of the hot pressing and compounding operation.
[0030] Please see the attached Figure 6 and attached Figure 8 The mounting assembly 12 includes a shell 121, the top of the shell 121 is fixedly connected to the lower surface of the stamping plate 9, a mounting groove 122 is opened inside the shell 121, and the outer wall of the mounting column 133 is set inside the mounting groove 122.
[0031] Specifically, the top of the shell 121 of the mounting component 12 is fixedly connected to the lower surface of the stamping plate 9, ensuring that the mounting component 12 and the stamping plate 9 form a stable integral structure, and the mounting groove 122 is used to accommodate the second mounting column 133 in the fixing component 13. The fixing component 13 can be accurately installed in the mounting component 12 through the cooperation of the second mounting column 133 and the mounting groove 122, thereby establishing a stable connection relationship with the stamping plate 9, and finally connecting the heating plate 11 to the stamping plate 9. They can move in coordination during the working process. When performing hot pressing and compounding operations on leather fabrics and linings, the movement of the stamping plate 9 can be transmitted to the heating plate 11 through the mounting component 12 and the fixing component 13, ensuring that the heating plate 11 can accurately reach the working position. When the stamping plate 9 needs to be replaced, by rotating the connecting block 131, the connecting block 131 drives the second mounting column 133 to rotate inside the mounting groove 122, and finally the stamping plate 9 is pulled out, thereby facilitating disassembly.
[0032] Please see the attached Figure 2 and attached Figure 3 The surface of the handle 83 is provided with anti-slip particles; the temperature of the heating plate 11 can be controlled by the controller 5, and the heating temperature range is 50 ℃ -150 ℃.
[0033] Specifically, when a person grasps handle 1 (83), the anti-slip particles increase the surface roughness between the hand and the handle, increasing friction across the contact area. During the downward pressure on handle 1 (83), even if the hand is sweating or in other slippery conditions, the anti-slip particles effectively prevent the hand from slipping off the handle, allowing the operator to apply force more steadily and effectively, ensuring accurate and consistent operation. This not only improves work efficiency but also prevents operational errors caused by hand slippage, ensuring safe use of the equipment and enabling smooth thermal lamination of the leather fabric and lining.
[0034] The operator can set the target temperature on the controller 5 according to the material properties of the leather fabric and lining and the composite process requirements. The controller 5 will send a corresponding electrical signal to the heating plate 11. The heating element in the heating plate 11 generates heat according to the received electrical signal. When the temperature approaches the set upper limit of 150°C, the controller 5 will automatically adjust the current to reduce the heat generated by the heating element. When the temperature is lower than the set lower limit of 50°C, the controller 5 will increase the current to quickly heat up the heating element and maintain the temperature of the heating plate 11 within the range of 50°C-150°C.
[0035] Please see the attached Figure 1 -Attached Figure 3 , a process for laminating leather fabric and lining, comprising the following steps: S1. First, lay the leather fabric flat on the workbench 1, then place the lining on top of the leather fabric and adjust the positions of the two; S2. Start the controller 5 to heat the heating plate 11 to a suitable temperature. Press the stamping plate 9 downward through the handle 10. The extrusion assembly 8 pushes the stamping plate 9 downward. The heating plate 11 performs hot pressing and laminating on the leather fabric and the lining. The different shapes of the hot pressing blocks on the heating plate 11 are used to form different shapes on the surface of the leather fabric. S3. After the hot pressing lamination is completed, the laminated leather fabric and lining are cooled, and the natural cooling time is about 5-15 minutes.
[0036] Specifically, first, lay the leather fabric flatly on the workbench 1, ensuring that its surface is free of wrinkles and curls. Then, gently place the lining on top of the leather fabric. At this time, it is necessary to adjust the relative positions of the two according to the design requirements and quality standards of the product so that the edges of the leather fabric and the lining are aligned, laying a good foundation for subsequent composite operations.
[0037] After adjusting the material position, controller 5 is activated. This sends a command to heating plate 11, causing it to begin heating. The temperature of heating plate 11 is precisely adjusted to the appropriate value based on the material properties of the leather fabric and lining. Once heating plate 11 reaches the desired temperature, the operator grasps handle 2 10 on punch plate 9 and applies downward force. During this process, extrusion assembly 8 works in conjunction with the downward pressure of handle 2 10, causing handle 1 83 in extrusion assembly 8 to rotate, thereby driving extrusion rod 82 to push punch plate 9 downward in a steady motion.
[0038] When the stamping plate 9 drops to a certain position, the heating plate 11 below it contacts the leather fabric and the lining. The heat generated by the heating plate 11 and the downward pressure work together to make the leather fabric and the lining fit tightly together, realizing hot pressing compounding. Hot pressing blocks of different shapes are provided on the heating plate 11. During the hot pressing process, these hot pressing blocks will press out corresponding shapes on the surface of the leather fabric, which not only adds a unique appearance effect to the product, but also enhances the structural stability and three-dimensional sense of the leather fabric to a certain extent.
[0039] After the hot pressing composite is completed, the process adopts the natural cooling method, and the cooling time is roughly controlled at 5-15 minutes. During the natural cooling process, the composite material gradually dissipates heat, and its internal molecular structure will be further stabilized and solidified, thereby ensuring the durability of the composite effect. If the cooling speed is too fast, the leather fabric and lining may cause internal stress due to uneven shrinkage, which may lead to product deformation, cracking and other quality problems. After natural cooling, the physical properties of the product tend to be stable and can be processed later or put into use directly.
[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
