Technical Field

[0001] This utility model relates to the field of dry production technology of synthetic leather, and in particular to an adjustable pressure roller mechanism for anti-separation paper edge rolling of synthetic leather. Background Technology

[0002] In the dry manufacturing process of synthetic leather, release paper is widely used as a material carrier for drying in an oven. However, the release paper is prone to curling at the oven inlet and outlet, causing surface-attached materials to rub against it and affecting product quality. Current technology often involves manually supporting the release paper at the oven inlet to prevent curling. This method significantly increases labor costs, and the long hours spent in this monotonous work can lead to decreased concentration and pose significant safety hazards.

[0003] Therefore, it is necessary to propose an adjustable pressure roller mechanism for anti-separation paper edge rolling of synthetic leather to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable pressure roller mechanism for preventing the release of paper from synthetic leather, so as to solve the problems of low efficiency and safety hazards associated with manual operation in preventing edge curling.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A fastening nut is threaded onto the screw and is located on the outer side of the mounting frame. An electric hydraulic cylinder is fixedly mounted at the bottom of the mounting frame. A connecting shaft is fixedly mounted on the mounting block at the output end of the electric hydraulic cylinder. Tensioning sprockets are rotatably mounted on both ends of the connecting shaft. An oven chain is engaged on the tensioning sprockets. The tensioning sprockets and the transmission sprockets are connected by the oven chain drive.

[0007] Preferably, the mounting frame is provided with an oven on its outer periphery, and the mounting frame is fixedly connected to the door panel of the oven.

[0008] Preferably, the mounting frame is provided with a discharge port, which is flush with the feed port of the drying oven.

This, combined with an electric hydraulic cylinder driving a tension sprocket and an oven chain driving a transmission sprocket, adjusts the height of the lower pressure roller, ensuring precise alignment between the roller gap and the discharge port, adapting to the conveying needs of release paper of different thicknesses. The release paper is first pre-pressed at the edges by an anti-rolling pressure block within the adjusting block; its smooth arc surface prevents scratches and smooths out slight bends. Then, it is pressed a second time by the upper and lower pressure rollers, completely preventing material abrasion caused by edge curling and improving product quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] This utility model provides, for example Figures 1-4 The diagram shows an adjustable pressure roller mechanism for anti-separation paper curling in synthetic leather. It includes a mounting frame 1, with right-angle rods 2 fixedly mounted on both the left and right sides of the mounting frame 1. A rotating rod 3 is rotatably mounted on each right-angle rod 2. An adjustable nut 4 is threaded onto the rotating shaft connecting the right-angle rods 2 and the rotating rod 3. A long shaft is fixedly mounted at one end of the rotating rod 3, and an upper pressure roller 5 is rotatably mounted on the long shaft. A lower pressure roller 6 is located below the upper pressure roller 5. A pressure roller shaft 7 is fixedly connected to one end of the lower pressure roller 6, and one end of the pressure roller shaft 7 is slidably mounted on a through groove on the side of the mounting frame 1. A transmission sprocket 8 is fixedly mounted in the middle section of the pressure roller shaft 7, which is close to the mounting frame 1. A pad 9 is provided on the outer side. One end of the pressure roller 7 is rotatably mounted on the pad 9. A screw 10 is movably mounted on the pad 9, and the screw 10 extends from the through groove into the interior of the mounting frame 1. A fastening nut 11 is threaded on the screw 10. The fastening nut 11 is located on the outer side of the mounting frame 1. An electric hydraulic cylinder 12 is fixedly mounted at the bottom of the mounting frame 1. A connecting shaft 13 is fixedly mounted on the mounting block at the output end of the electric hydraulic cylinder 12. Tensioning sprockets 14 are rotatably mounted on both ends of the connecting shaft 13. An oven chain 15 is engaged on the tensioning sprockets 14. The tensioning sprockets 14 and the transmission sprocket 8 are connected by the oven chain 15.

[0024] The mounting frame 1 is provided with an oven 16 on its outer periphery, and the mounting frame 1 is fixedly connected to the door panel of the oven 16.

[0025] The mounting frame 1 is provided with a discharge port 17, which is flush with the feed port of the oven 16. There is a gap between the upper pressure roller 5 and the lower pressure roller 6, and the gap is at the same horizontal height as the discharge port 17.

[0026] Both ends of the upper pressure roller 5 are rotatably connected to the long shaft on the rotating rod 3 via bearings.

[0027] The oven chain 15 is connected to the drive assembly inside the oven 16, and the oven chain 15 passes through the mounting frame 1.

[0028] A connecting block 18 is movably mounted on the pressure roller 7, and one end of the connecting block 18 is slidably connected in the groove of the mounting frame 1.

[0029] In this embodiment, in order to prevent the release paper from curling, the adjustable nut 4 is loosened and the rotating rod 3 on the right-angle rod 2 is rotated to adjust the distance and angle between the upper pressure roller 5 and the lower pressure roller 6. After the adjustment is completed, the rotating rod 3 is fixed by the adjustable nut 4.

[0030] After adjusting the upper pressure roller 5, in order to better match the position and angle changes of the upper pressure roller 5, the height of the lower pressure roller 6 is adjusted by dynamically adjusting the transmission sprocket 8. Driven by the electric hydraulic cylinder 12, the connecting shaft 13 moves up and down. The tension sprocket 14 fixedly installed on the connecting shaft 13 moves with the connecting shaft 13. The tension sprocket 14 and the transmission sprocket 8 are connected by the oven chain 15 on the oven 16. Since the oven chain 15 between the tension sprocket 14 and the transmission sprocket 8 is designed to be in a straight and taut state, the oven chain 15 can ensure that the tension sprocket 14 and the transmission sprocket 8 move synchronously, thereby realizing the height position adjustment of the transmission sprocket 8.

[0031] During the adjustment of the height of the transmission sprocket 8, in order to ensure that the position of the lower pressure roller 6 remains unchanged after the height of the transmission sprocket 8 is adjusted without affecting the rotation of the pressure roller shaft 7 on the transmission sprocket 8, the pad 9 and the screw 10 can be used to achieve this. The pressure roller shaft 7 is rotatably mounted on the pad 9, and the screw 10 is movably mounted on the pad 9. When fixing the height of the lower pressure roller 6, the pad 9 is tightly fixed to the side wall of the mounting frame 1 by the fastening nut 11 to prevent the lower pressure roller 6 from changing its height position due to the slippage of the pad 9.

[0032] Example 2

[0033] like Figure 1 As shown in Figure 4, one end of the connecting block 18 is fixedly connected to an adjusting block 19. The adjusting block 19 is C-shaped, and an anti-rolling pressure block 20 is rotatably installed on the upper side of the adjusting block 19. The bottom surface of the anti-rolling pressure block 20 is close to the inner bottom surface of the adjusting block 19, and the end of the anti-rolling pressure block 20 is set as a smooth arc surface 21.

[0034] In this embodiment, before the release paper passes through the upper pressure roller 5 and the lower pressure roller 6, its edge passes through the adjusting block 19. Specifically, the edge of the release paper passes between the anti-rolling pressure block 20 and the inner bottom surface of the adjusting block 19. When the release paper slides past the adjusting block 19, the anti-rolling pressure block 20 presses against the upper surface of the release paper, thereby smoothing out the slightly bent position on the release paper and preventing the pressing of the upper pressure roller 5 and the lower pressure roller 6 from causing the bent area of ​​the release paper to be completely bent or broken. The smooth arc surface 21 can prevent the anti-rolling pressure block 20 from scratching the release paper.

[0035] The working principle of this utility model is as follows: By loosening the right-angle rod 2 and the adjustable nut 4 on the rotating shaft connected to the rotating rod 3, the rotating rod 3 is rotated to adjust the distance and angle between the upper pressure roller 5 and the lower pressure roller 6. After fixing, the lower pressure roller 6 is locked in place by the cooperation of the pad block 9, the screw 10, and the fastening nut 11. The electric hydraulic cylinder 12 drives the connecting shaft 13 to drive the tension sprocket 14 to move up and down. The oven chain 15 drives the transmission sprocket 8 and the pressure roller shaft 7 to adjust synchronously, ensuring that the gap between the upper and lower pressure rollers is at the same level as the discharge port of the mounting frame 1. The release paper is first pressed by the anti-rolling pressure block 20 in the adjusting block 19 to smooth out the slight bends. Then, it is pressed by the upper and lower pressure rollers and finally enters the oven 16 from the discharge port 17. This achieves anti-rolling while ensuring conveying stability. The oven chain 15 is linked with the oven drive assembly to ensure overall transmission synchronization.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
