[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1-5, which is the first embodiment of the present utility model, provides a calendering device for artificial leather processing, which includes a workbench 1, a conveyor belt 11 installed on the surface of the workbench 1, and a calendering roller 12 located on the surface of the conveyor belt 11. The conveyor belt 11 is connected to an external driving structure. The calendering roller 12 is provided with a heating wire inside. A positioning member 2 is installed on the inner side of the workbench 1 and on the top of the conveyor belt 11. A driving member 3 is installed on the top of the workbench 1 and on one side of the positioning member 2.

[0026] The positioning member 2 includes a positioning plate 21 located on the inner side of the workbench 1. The positioning plate 21 is set in a L shape. A first pulley group 22 is movably installed on the inner side of the positioning plate 21. A second pulley group 23 is installed inside the positioning plate 21. The first pulley group 22 and the second pulley group 23 are perpendicular and staggered. The first pulley group 22 and the second pulley group 23 are arranged at equal distances. The first pulley group 22 can provide support for both sides of the artificial leather to prevent the artificial leather from deflecting during transportation. The second pulley group 23 can form a more complete working surface on the top of the artificial leather. The combination of the two can improve the overall flatness and stability of the artificial leather.

[0027] A groove 25 is provided on the inner side of the workbench 1 , and an electric push rod 24 is installed inside the groove 25 . The output end of the electric push rod 24 is fixedly connected to the positioning plate 21 , so that the positioning plate 21 can position artificial leathers of different widths.

[0028] The driving member 3 includes a motor 31 installed inside the workbench 1. The output end of the motor 31 is fixedly connected to a screw rod 32. One end of the screw rod 32 extends to the top of the workbench 1. The top of the workbench 1 and the side away from the screw rod 32 are fixedly connected to a slide rod 33. The top of the screw rod 32 is movably connected to an anti-sway plate 37. The anti-sway plate 37 is set in an L shape. The bottom of the anti-sway plate 37 is fixedly connected to the outside of the workbench 1, which can maintain the stability of the screw rod 32 and prevent it from deflecting. At the same time, it can facilitate the driving of the calendering roller 12.

[0029] The surfaces of the screw rod 32 and the slide rod 33 are both sleeved with a slider 34 , the slider 34 is threadedly connected to the screw rod 32 , and the slider 34 is movably sleeved with the slide rod 33 .

[0030] A connecting rod 35 is fixedly connected to one side of the slider 34. The connecting rod 35 is L-shaped. A connecting ring 36 is fixedly connected to the bottom of the connecting rod 35. Both ends of the calendering roller 12 are located inside the connecting ring 36 and are movably connected to it to facilitate the operation of the calendering roller 12.

[0031] A telescopic rod 351 is installed on the top of a group of connecting rods 35. Figure 4 As shown, the top of the connecting rod 35 connected to the slide rod 33 is connected to the telescopic rod 351, and the slider 34 is connected to the connecting rod 35 through the telescopic rod 351, which facilitates the disassembly of the calendering roller 12.

[0032] An electric motor 38 is installed on the outside of a set of connecting rings 36, and a coupling 381 is installed on the output end of the motor 38. The other end of the coupling 381 extends to the inside of the connecting ring 36 and is connected to the calendering roller 12. A plate is fixedly connected to one side of the motor 38, and the top of the plate is connected to the connecting rod 35 to prevent the motor 38 from rotating. At the same time, a groove is provided on the inside of the workbench 1 to facilitate the lifting and lowering of the motor 38, which can prevent it from getting stuck with the inside of the workbench 1.

[0033] The outer side of another set of connecting rings 36 is provided with bolts 39, and the inner side of the bolts 39 is fixedly connected to a rotating ring 391. The diameter of one end of the bolts 39 is larger than that of the connecting ring 36, which can limit the calendering roller 12 and ensure the stability of the calendering roller 12 during rotation.

[0034] A threaded groove 392 and a rotating groove 393 are provided on the other side of the calendering roller 12. The threaded groove 392 is located inside the rotating groove 393. One end of the bolt 39 passes through the connecting ring 36 and extends to the interior of the calendering roller 12 and is threadedly connected to the threaded groove 392. The rotating ring 391 is located inside the rotating groove 393 and is movably connected to it to prevent it from wearing one end of the calendering roller 12.

[0035] During use, the artificial leather is placed on the surface of the conveyor belt 11 and driven by an external driving force to move the artificial leather slowly. At the same time, the electric push rod 24 can be started according to the width of the artificial leather to push the positioning plate 21 to move to both sides of the artificial leather until the first pulley group 22 contacts both sides of the artificial leather. During this process, the first pulley group 22 can provide support for both sides of the artificial leather to prevent the artificial leather from deflecting during transportation. The second pulley group 23 can form a more complete working surface on the top of the artificial leather. The use of the two can improve the overall flatness and stability of the artificial leather. At the same time, it can also make the artificial leather move more smoothly. While the contact area is uniform, the friction between it and the workbench 1 is reduced to reduce the problem of low work efficiency caused by poor movement of the artificial leather, thereby improving production efficiency.

[0036] At the same time, when one end of the artificial leather moves to the outside of the positioning plate 21, that is, the bottom of the calendering roller 12, the motor 38 is started to drive the calendering roller 12 and the conveyor belt 11 to rotate synchronously and in the opposite direction through the coupling 381. In this way, the artificial leather can be evenly stretched and stretched under the extrusion of the conveyor belt 11 and the calendering roller 12, avoiding the generation of fine foreskin and wrinkles, thereby improving the flatness of the artificial leather product. At the same time, the heating wire inside the calendering roller 12 can improve the efficiency of the calendering operation. In this way, the problem that the calendering roller 12 cannot fully calender the artificial leather due to the presence of the positioning structure can be avoided.

[0037] When the calendering roller 12 needs to be replaced, first start the motor 31 to drive the screw rod 32 to rotate, and drive the connecting rod 35, connecting ring 36, motor 38, calendering roller 12 and bolt 39 to rise through the slider 34 until they rise to the top of the workbench 1, then the bolt 39 can be rotated in the opposite direction to cancel the connection with the inner thread groove 392 of the calendering roller 12, and at the same time, the rotating ring 391 is disconnected from the rotating groove 393, so that the limit on one side of the calendering roller 12 can be canceled, and at the same time, the connecting rod 35 is pushed to retract through the telescopic rod 351, and drive the connecting ring 36 to cancel the connection with one end of the calendering roller 12, and the other side can be removed by removing the coupling 381, so that the calendering roller 12 can be disassembled. When installing, the operation is reversed, so that the purpose of quickly replacing the calendering roller 12 can be achieved.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. 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 spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
