DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will further elaborate on this application in conjunction with the attached Figure 1 - attached Figure 4 drawings, for a more detailed description of this application.

[0031] A calendering device for the production of composite leather, referring to Figure 1 and Figure 2 and Figure 3 , includes a support frame 1, a calendering mechanism 2 provided on the support frame 1, and a conveying mechanism 3. The conveying mechanism 3 is located on one side of the calendering mechanism 2. The core of the calendering mechanism 2 is driven by a calendering motor 21, and its output end is directly connected to a rotating rod 22. A secondary bevel gear 23 is fixed on the rotating rod 22. It is also matched with a sliding block 204 inside a sliding cylinder 202 through a sliding slot 203. The sliding block 204 and a primary bevel gear 201 are respectively fixed on the inner surface and the lower end of the sliding cylinder 202 by welding. The sliding slot 203 has a certain vertical length, and the sliding block 204 is arranged in the sliding slot 203 to realize the sliding connection between the sliding cylinder 202 and the rotating rod 22. The primary bevel gear 201, the secondary bevel gear 23, and two driven bevel gears 24 provided on the calendering roller 25 form a meshing transmission mechanism, finally driving the two calendering rollers 25 to rotate relatively. In addition, a movable screw 29 with adjustable height is provided above the support frame 1, and a movable frame 27 connected to its lower end is matched with one of the calendering rollers 25 for adjusting the distance between the calendering rollers 25.

[0032] Referring to Figure 2 and Figure 3 , by providing a calendering mounting frame 20 for the calendering motor 21 and firmly connecting it to the support frame 1, this structure not only enhances the stability of the calendering motor 21 but also facilitates its maintenance and replacement. The sliding fit design of the moving slots 28 opened on both sides of the support frame 1 and the movable frame 27 realizes the precise adjustment of the distance between the calendering rollers 25, while ensuring the smoothness and stability during the adjustment process. A rotating slot 205 is opened on the movable frame 27, and a bearing is installed in the rotating slot 205. The inner ring of the bearing is rotationally connected to the sliding cylinder 202, thereby realizing the vertical lifting of the sliding cylinder 202 together with the movable frame 27 and the sliding cylinder 202 can also rotate relative to the movable frame 27.

[0033] Referring to Figure 4, The conveying mechanism 3 is respectively installed on both sides of the support frame 1 and is mainly supported by the chassis 30. A conveying motor 35 is provided on the chassis 30, and its output end drives the conveying rod 32 to rotate. Power transmission is achieved through two driving wheels 33 fixed on the conveying rod 32 via a conveyor belt 36. A driven wheel 38 is sleeved inside the conveyor belt 36 to ensure the smooth operation of the conveyor belt 36. A positioning plate 301 is fixed above the chassis 30. Two positioning brackets 39 at the lower end of the positioning plate 301 respectively correspond to the two driven wheels 38, playing a role in stable support and positioning, and ensuring the stability and efficiency of the entire conveying system.

[0034] Refer to Figure 4 , The conveying motor 35 is firmly fixed on the chassis 30 through the conveying mounting bracket 34, which not only enhances the stability of the conveying motor 35 but also effectively reduces vibration and noise during operation. The conveying groove 31 opened on the chassis 30 provides stable support and guidance for the conveying rod 32, ensuring the stability and precision of the conveying rod 32 during high-speed rotation. The positioning wheel 37 provided on the positioning plate 301 is used in cooperation with the conveyor belt 36, effectively preventing the conveyor belt 36 from shifting and slipping during operation, and further improving the accuracy and stability of conveying.

[0035] The implementation principle of the embodiment of this application is as follows: In the calendering device for composite leather production, through the calendering mechanism 2, first start the calendering motor 21, and its output power is transmitted to the secondary bevel gear 23 through the rotating rod 22. At the same time, the rotating rod 22 can drive the sliding block 204 in the sliding cylinder 202 to rotate through the sliding card slot 203, so that the sliding cylinder 202 can drive the primary bevel gear 201 to rotate. Subsequently, through the meshing action between the secondary bevel gear 23, the primary bevel gear 201 and the two driven bevel gears 24, the two calendering rollers 25 are driven to rotate in opposite directions. According to production requirements, the moving screw 29 can be adjusted to move the moving frame 27 up and down, so that the moving frame 27 can drive the sliding cylinder 202 to move through the rotating slot 205, enabling the sliding block 204 to slide in the sliding card slot 203 while maintaining rotation, thereby finely adjusting the gap between the two calendering rollers 25 to adapt to composite leather raw materials of different thicknesses or materials.

[0036] By providing a calendering mounting bracket 20 for the calendering motor 21 and firmly connecting it to the support frame 1, this structure not only enhances the stability of the calendering motor 21 but also facilitates its maintenance and replacement. The sliding fit design between the moving slots 28 opened on both sides of the support frame 1 and the moving frame 27 realizes the precise adjustment of the distance between the calendering rollers 25, while ensuring the smoothness and stability during the adjustment process. The rotational connection between the rotating slot 205 opened on the moving frame 27 and the sliding cylinder 202 realizes the stable lifting of the calendering rollers 25 in the vertical direction.

[0037] After starting the conveyor motor 35 on one side of the chassis 30 through the conveyor mechanism 3, the output power is transmitted to the two driving wheels 33 through the conveyor rod 32. The frictional force between the driving wheels 33 and the conveyor belt 36 causes the conveyor belt 36 to start circulating. At the same time, the driven wheel 38 rotates under the drive of the conveyor belt 36 to ensure the stable operation of the conveyor belt 36. The positioning plate 301 and the positioning frame 39 below it provide a firm support for the driven wheel 38 to prevent it from shifting during operation. The composite leather raw material to be calendered is placed in the conveyor mechanism 3 and sent into the calendering mechanism 2 for processing as the conveyor belt 36 moves. After processing, it is sent out by the conveyor mechanism 3 again to achieve a continuous and efficient production process.

[0038] The conveyor motor 35 is firmly fixed on the chassis 30 through the conveyor mounting bracket 34, which not only enhances the stability of the conveyor motor 35 but also effectively reduces the vibration and noise during operation. The conveyor groove 31 opened on the chassis 30 provides stable support and guidance for the conveyor rod 32 to ensure the stability and accuracy of the conveyor rod 32 during high-speed rotation. The positioning wheel 37 provided on the positioning plate 301 is used in cooperation with the conveyor belt 36 to effectively prevent the conveyor belt 36 from shifting and slipping during operation, further improving the accuracy and stability of the conveyance.

The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
