Description

Technical Field

[0001] The present invention relates to the technical field of leather processing, and in particular to a leather laminating device and method with changeable modes. Background Art

[0002] In the field of industrial manufacturing, the processing method of covering the surface of the mold with leather is widely used, and is common in industries such as automotive interior, furniture manufacturing, and luggage production. It can give the product a beautiful appearance and a comfortable touch.

[0003] The traditional leather covering mold processing process includes several key steps. First, glue needs to be evenly applied on the surface of the lower mold. The quality of the glue application directly affects the fitting effect between the leather and the lower mold. If the glue is unevenly applied, it may cause the leather to be partially loosely fitted, resulting in bubbles, wrinkles and other problems, reducing the overall quality of the product. Next, in order to make the glue reach the best viscosity, an infrared lamp module is usually used to activate the glue. The specific wavelength of light emitted by the infrared lamp can accelerate the chemical reaction of the glue, so that it quickly reaches a state suitable for bonding. Finally, the upper mold drives the leather to be pressed onto the surface of the lower mold after glue coating to complete the fitting of the leather and the mold.

[0004] In the above process, in order to ensure the consistency and efficiency of the glue activation effect and improve the processing quality, the shape design of the lamp tube module needs to correspond to the shape of the lower mold. The molds used for different products have different shapes, including flat, curved, special-shaped and other forms. Therefore, for molds of different shapes, different lamp tube modules need to be matched. For example, in the leather covering processing of car seat interiors, the mold shapes of different parts of the seat are quite different. The molds in the backrest, seat cushion and other positions need to be specially designed with matching lamp tube modules to ensure that the glue can be evenly activated in all parts.

[0005] However, the current processing equipment has obvious shortcomings. The lamp tube module and the leather material transmission structure are integrated. When different lamp tube modules need to be replaced to adapt to molds of different shapes, the available operation methods are extremely limited.

[0006] One way is to disassemble the lamp tube, but the infrared lamp tube generates a lot of heat during operation, and the temperature of the lamp tube module is high. Before disassembling the lamp tube, you must wait for the lamp tube module to cool down, otherwise the high temperature may cause burns to the operator, and may also damage the lamp tube and related equipment. This cooling waiting process will take a lot of time, resulting in a significant reduction in production efficiency. For example, in the process of continuous production of products of different shapes, each time the mold is changed, it is necessary to wait for the lamp tube module to cool down, and the waiting time may be as long as ten minutes or even dozens of minutes each time, which seriously affects the overall production capacity of the production line.

[0007] Another way is to use external handling equipment to replace the leather transmission structure connected to the lamp module as a whole. Since the leather transmission structure is usually large in size and heavy in weight, the overall replacement requires professional handling equipment, and the operation process is complicated and cumbersome. In addition, the scheduling and use of handling equipment also requires additional time and cost. At the same time, frequent overall replacement may also cause certain damage to the leather transmission structure, affecting its service life and transmission accuracy. Summary of the invention

Further, one end of the leather material can be clamped between the support roller 121 and the squeeze roller 122, and the leather material is moved to the composite functional table 300 through the support roller 121 and the squeeze roller 122. At the same time, the cutter 131 in this embodiment can cut leather materials of different lengths in the horizontal direction according to actual use requirements, and the present invention does not limit its specific structure.

[0029] See also Figure 3 and Figure 4 As shown, the transmission mechanism 200 includes a base frame 210, a slide 220 and a connecting plate 240. The base frame 210 is provided with a first horizontal module 211 extending horizontally toward the laminating mechanism 400. The slide 220 is slidably connected to the first horizontal module 211, and a first lifting module 221 extending along the height direction of the transmission mechanism 200 is provided thereon. The connecting plate 240 is slidably connected to the first lifting module 221, and the platform body 310 is detachably connected to the connecting plate 240. Based on the above structure, the connecting plate 240 can be flexibly moved in the horizontal and / or vertical directions, thereby driving the laminating function platform to be adjusted according to actual usage requirements.

[0030] Specifically, see Figures 3 to 7As shown, the carriage 220 in this embodiment moves linearly on the base frame 210 through the driving motor, and the connecting plate 240 is lifted and lowered along the carriage 220 through the lifting driving assembly 230. The lifting driving assembly 230 includes a rotary driver 231, a transmission rod 232, a gear 233 and a rack 234. The rotary driver 231 is arranged on the base frame 210. The transmission rod 232 connects the working end of the rotary driver 231 and the gear 233. The rack 234 is arranged on the connecting plate 240 and extends along the height direction of the transmission mechanism 200. The gear 233 is meshed with the rack 234 to drive the connecting plate 240 to move up and down. Based on this structural setting, on the one hand, its carrying capacity can be improved, and on the other hand, it can also maintain stable position accuracy in applications that require high-precision positioning and stable operation, reduce vibration and deformation, thereby reducing the mutual wear between the connecting plate 240 and the composite functional table 300 and extending its service life.

[0031] In the present embodiment, the connection plate 240 and the composite functional platform are configured to be detachably connected, so positioning is required during the disassembly and assembly process to ensure the accuracy of the connection position. Based on this, the connection plate 240 in the present embodiment is also provided with a positioning pin 241, and the positioning pin 241 is protrudingly arranged on the top surface of the connection plate 240. The composite functional platform 300 is provided with a positioning hole 312, and the positioning hole 312 is arranged one-to-one with the positioning pin 241, thereby realizing the positioning connection between the connection plate 240 and the composite functional platform 300. In order to further improve the relative stability between the two, the composite functional platform and the connection plate 240 are also fixed and limited for a second time by connecting parts such as bolts.

[0032] See also Figure 5 and Figure 6 As shown, the composite functional table 300 in this embodiment includes a table body 310, a plurality of bidirectional plug-in columns 320, a skin-lifting component 330 and a light tube module 340. The table body 310 is detachably connected to the transmission mechanism 200. The skin-lifting component 330 is connected to the table body 310 to pull the leather material 500 to be laminated. The light tube module 340 is arranged on the bottom surface of the table body 310, and a plurality of bidirectional plug-in columns 320 are arranged around the table body 310. The table body 310 serves as an installation and connection platform for the skin-lifting component 330 and the light tube module 340, and positioning holes 312 are respectively provided on both sides thereof to be detachably connected to the connecting plate 240.

[0033] Furthermore, the table body 310 in this embodiment is configured as a rectangular plate structure, to which four bidirectional plug-in columns 320 are connected, and the four bidirectional plug-in columns 320 are respectively arranged at the four corners of the table body 310, thereby forming a stable support structure for the table body 310. Specifically, the bidirectional plug-in columns 320 in this embodiment extend along the thickness direction of the table body 310, and the extended thickness is greater than the thickness of the table body 310. The bidirectional plug-in columns 320 include a first body 321, a first plug-in protrusion 322 and a first plug-in groove 323. The first body 321 is connected to the table body 310, the first plug-in groove 323 is recessed by the top surface of the first body 321, and the first plug-in protrusion 322 is protruding outward from the first body 321 along the extension direction of the first body 321.

[0034] In this embodiment, the skin-lifting assembly 330 is used to move and pull the leather cut by the leather processing mechanism 100 to make its surface smooth and avoid bubbles or wrinkles during the subsequent lamination process. Specifically, the skin-lifting assembly 330 includes a leather support plate 331 and a plurality of skin-lifting claws 332. The leather support plate 331 is detachably connected to the platform 310 to support the leather 500 to be laminated. Specifically, a plurality of adjustment holes 313 are provided on the platform. The leather support plate 331 can be connected to different adjustment holes by connecting parts such as screws. The plurality of skin-lifting claws 332 are arranged on opposite sides of the leather support plate 331 and can move along the transmission direction of the leather 500 to be laminated. Specifically, see Figure 8 As shown, the leather support plate 331 in this embodiment is used to support the leather to prevent the middle part of the leather from collapsing. The leather support plate 331 and the platform 310 are configured as a detachable connection structure, so that the support plate can be set at different positions or installed in different quantities according to actual use requirements. The leather lifting clamp 332 moves through the second horizontal module 311. In the actual operation process, the leather lifting clamp 332 needs to move to the end of the second horizontal module 311 facing the leather processing mechanism 100 to wait for the leather to be clamped. After clamping the leather, it can drive the leather to move away from the leather processing mechanism 100 synchronously, and at the same time support the leather 500 to be laminated on the leather support plate 331, which is also configured as a detachable connection structure with the platform 310. Further, in this embodiment, two leather lifting clamps 332 are provided on opposite sides of the leather to pull both sides of the leather at the same time.

[0035] In the present embodiment, the lamp tube module 340 is fixedly connected to the bottom surface of the table body 310, and can be moved synchronously with the table body 310 to the top of the lower mold 431. It should be noted that in the actual processing process, glue will be coated on the lower mold 431. In the process of waiting for coating, the adhesive force of the glue will gradually decrease as its solidification degree increases. Therefore, the lamp tube module 340 is required to heat and bake it to activate the glue. Furthermore, in order to adapt to different lower molds 431, it is often necessary to frequently replace different lamp tube modules 340 so that the glue can be in a better state during the coating process.

The upper mold 421 is arranged on the mounting plate 423. The plurality of material moving jaws 422 are arranged around the upper mold 421. The mounting plate 423 is used to provide a mounting and connecting platform for the upper mold 421 and the material moving jaws 422. The plurality of material moving jaws 422 are used to clamp the leather material 500 to be laminated on the transfer platform 310. After the material moving jaws 422 clamp the edge of the leather material, the skin lifting jaws 332 will release the leather material, thereby enabling the leather material to move with the upper mold assembly 420 to the top of the lower mold assembly 430. Specifically, the lifting driver 425 in this embodiment is preferably a linear motor.
