[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0021] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the attached Figure 1 , and is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting this application.

[0022] like Figure 1-4 As shown, a pressing device for TPR bonding leather includes a base plate 1, a lifting plate 2, a column 3, a top plate 4, a spring 5, and a support 7. There are two columns 3, and they are fixedly arranged on the base plate 1 in an axially vertical direction. The slider 15 slides with the column 3 to support the lifting and lowering of the lifting plate 2. The top of the column 3 is fixedly connected to the top plate 4. A spring 5 is arranged between the top plate 4 and the lifting plate 2, and the two ends of the spring 5 are respectively connected to the top plate 4 and the lifting plate 2. A support 7 is fixedly provided on the top surface of the base plate 1. Multiple groups of adjustable supporting components are arranged on the support 7 and the lifting plate 2, and the adjustable supporting components on the two are relative.

[0023] Specifically, the column 3 is used to support the sliding and lifting of the slider 15 to support the lifting and lifting of the lifting plate 2. The top plate 4 is used to provide support for the spring 5. The spring 5 is configured to push the lifting plate 2 down through thrust, so that the adjustable supporting component on the lifting plate 2 and the adjustable component on the support 7 are close to each other, thereby pressing the TPR and leather.

[0024] like Figure 2 As shown, a connecting block 16 is fixedly provided on the side of the slider 15, and a cylinder 6 for driving the connecting block 16 to move up and down is fixedly provided on the base plate 1.

[0025] Specifically, the cylinder 6 telescopes and drives the connecting block 16 to rise and fall vertically, thereby causing the slider 15 to rise and fall with the connecting block 16, which in turn causes the lifting plate 2 to rise and fall. After the lifting plate 2 moves away from the support 7, a gap is generated in the adjustable supporting assembly. When the cylinder 6 contracts, the squeezed spring 5 pushes the lifting plate 2 down, causing the lifting plate 2 and the adjustable supporting assembly on the support 7 to generate a pressing force to press the TPR and leather, and the telescopic end of the cylinder 6 is movably connected to the connecting block 16. When the telescopic end of the cylinder 6 moves away from the connecting block 16, the thrust of the spring 5 continues to push the adjustable supporting assembly on the lifting plate 2 to press the TPR and leather.

[0026] like Figure 3 As shown, the adjustable supporting assembly includes a screw rod 8 and a supporting tray 13 . The screw rod 8 is screwed to the support 7 and the lifting plate 2 . One end of the screw rod 8 is detachably connected to the supporting tray 13 .

[0027] Specifically, the screw rod 8 is rotated to adjust the height to form areas of different heights to adapt to the shape. At the same time, the tray 13 can be disassembled and replaced to make the tray 13 of different shapes further adapt to the shape of TPR and leather bonding.

[0028] like Figure 4As shown, the adjustable supporting assembly also includes a bolt 11 and a mounting column 12. The mounting column 12 is fixedly connected to the supporting tray 13. A groove adapted to the mounting column 12 is provided at one end of the screw rod 8. A screw sleeve 10 is fixedly provided on the outer wall of the screw rod 8. The screw sleeve 10 has a screw hole screwed to the bolt 11. The screw hole on the screw sleeve 10 passes through the groove so that the end of the bolt 11 can extend into the groove. A limiting groove 14 for accommodating the end of the bolt 11 is provided on the outer wall of the mounting column 12.

[0029] Specifically, the bolt 11 can be screwed to be pulled out from or inserted into the inner side of the limiting groove 14 , thereby loosening or tightening the mounting post 12 , so as to facilitate the disassembly and assembly of the mounting post 12 .

[0030] like Figure 3 As shown, a rotary handle 9 is fixedly provided on one end of the screw rod 8 which faces away from the supporting tray 13 .

[0031] Specifically, the screw rod 8 can be easily screwed by the screw handle 9 , and the screw handle 9 can prevent slipping during screwing.

[0032] Preferably, the side of the tray 13 facing the TPR or leather is a flat surface or an inclined surface.

[0033] Specifically, the flat or inclined surface of the receiving tray 13 can be replaced to adapt to the shape of the TPR and leather to be pressed, and the mounting column 12 can be rotated on the screw rod 8 to adjust the tilt direction of the inclined surface receiving tray 13.

[0034] In the above structure, first the cylinder 6 is started to extend and drive the lifting plate 2 to rise, so that a gap is generated between the adjustable supporting components, and the TPR and leather to be pressed are placed between the lifting plate 2 and the adjustable supporting components on the support 7. Then the cylinder 6 is started to contract. After the cylinder 6 contracts, the compressed spring 5 recovers its elastic force to push the lifting plate 2 down. When the cylinder 6 stops, the thrust of the spring 5 can also make the adjustable supporting components on the lifting plate 2 cooperate with the adjustable supporting components on the support 7 to press the TPR and leather. Therefore, without using power Under certain circumstances, it can also be pressed for a long time, reducing energy consumption and being beneficial to energy conservation and emission reduction. When the pressed shape is irregular and needs to be adjusted to adapt to the pressed shape, the screw rod 8 is driven to rotate by the rotary handle 9, so that the screw rod 8 is lifted and lowered on the lifting plate 2 or the support 7, so as to adapt to the shape. At the same time, the mounting column 12 can be disassembled to replace the supporting tray 13 to adapt to the shape. Screwing the bolt 11 can make it withdrawn from the inner side of the limiting groove 14, so that the mounting column 12 can be removed. Screwing the bolt 11 in the opposite direction can make it inserted into the inner side of the limiting groove 14 to fix the mounting column 12.

[0035] The above shows and describes the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present application.
