Description

Technical Field

[0001] This utility model relates to the field of paper product processing technology, specifically to a pressing mechanism for paper product processing. Background Technology

[0002] In the process of refining paper products, whether it is thin paper or stiff cardboard, fine pressing is often required to meet the strict quality control requirements of subsequent production stages. This process effectively adjusts the physical properties of the paper or cardboard, achieving not only ideal flatness and a smoother, more uniform surface, but also precise thickness control to meet specific process standards, significantly increasing density, enhancing the overall texture and performance of paper products, and satisfying diverse usage needs.

[0003] Patent document CN220841662U3 discloses a pressing mechanism for paper product manufacturing. This device includes a processing table, with support legs fixedly connected to the bottom of the table, a support column fixedly connected to the top of the table, a top plate fixedly connected to the top of the support column, a hydraulic rod fixedly connected to the top of the top plate, and a pressure plate fixedly connected to the bottom of the hydraulic rod. A transmission assembly for loading and unloading paper products is provided on the top of the processing table. This pressing mechanism transports the paper products to the support table via a transport mechanism, placing them on top of a flip plate. Activating the hydraulic rod causes the pressure plate to move downwards, flattening the paper products. After flattening, a first motor is activated, driving a gear to rotate. The gear rotation drives two rotating shafts to rotate in opposite directions. The rotating shafts cause the flip plate to rotate downwards, and the paper products on top of the flip plate fall through the through-hole and feeding chute into the collection box for collection under gravity. This eliminates the need for manual feeding, ensuring high safety and saving time and labor.

[0004] However, during the sheeting process, there is a significant chance that the paper products may be wrinkled or folded before the sheeting is transported. If this occurs, residual wrinkles can easily remain inside the paper products during subsequent sheeting, severely affecting the overall quality of the paper products and reducing product quality and yield.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This paper product processing pressing mechanism, equipped with a shaping unit, can handle paper products of different thicknesses. Activating the hydraulic telescopic assembly pushes the driven shaft, causing the upper pressing roller to move downwards within the adjusting groove, adjusting the distance between the upper and lower pressing rollers.

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a pressing mechanism for paper product processing, including a device housing 1 and a conveyor belt 2. The conveyor belt 2 is disposed inside the device housing 1. A pressing device is installed inside the device housing 1. The pressing device includes a shaping unit and a pressing unit. The shaping unit is installed inside the device housing 1, and the pressing unit is installed inside the device housing 1.

[0024] The shaping unit includes a motor 7, which is mounted on the outside of the device housing 1. The output shaft of the motor 7 is driven by a transmission assembly 8. The other end of the transmission assembly 8 is driven by a rotating shaft 9. A lower pressing roller 10 is fixedly connected to the outer surface of the rotating shaft 9, located inside the device housing 1. A transmission gear 11 is driven by the outer surface of the rotating shaft 9, away from the transmission assembly 8. A connecting gear 12 is driven by the outer side of the transmission gear 11. A driven gear 13 is driven by the outer surface of the connecting gear 12. A connecting plate 14 is movably connected to the side of the transmission gear 11. A connecting plate 15 is movably connected to the outer side of the connecting plate 14. A driven shaft 16 is driven by the inside of the driven gear 13. An upper pressing roller 17 is fixedly connected to the outer surface of the driven shaft 16, located inside the device housing 1. A hydraulic telescopic assembly is fixedly connected to the outside of the device housing 1. 18. An adjustment groove 19 is provided on the inner side of the device housing 1. By installing a shaping unit, and then by activating the hydraulic telescopic component 18 for paper products of different thicknesses, the hydraulic telescopic component 18 pushes the driven shaft 16, which in turn drives the upper pressing roller 17 to move inside the adjustment groove 19, thereby moving the upper pressing roller 17 downwards and adjusting the distance between the upper pressing roller 17 and the lower pressing roller 10. Further, by activating the motor 7, the transmission component 8 is used for transmission, which causes the rotating shaft 9 to drive the transmission gear 11 and the connecting gear 12 to mesh. Then, through the connecting gear 12, the driven gear 13 drives the driven shaft 16, which in turn causes the upper pressing roller 17 to rotate, thereby assisting in unfolding the paper product before pressing, thereby improving the flatness of the pressed paper product and avoiding wrinkles during pressing.

[0025] The transmission assembly 8 consists of two meshing bevel gears. Bevel gear one is fixedly connected to the output shaft of motor 7, and bevel gear two is fixedly connected to the outer surface of rotating shaft 9. Thus, by starting motor 7, bevel gear one and bevel gear two mesh with each other, thereby causing rotating shaft 9 to rotate.

[0026] A water storage tank 3 is fixedly connected to the side of the device housing 1. A transfer pipe 4 is fixedly connected to the side of the water storage tank 3. A diversion pipe 5 is fixedly connected to the other end of the transfer pipe 4. Spray pipes 6 are fixedly connected to the upper and lower ends of the diversion pipe 5. Water inside the water storage tank 3 is transferred to the inside of the diversion pipe 5 through the transfer pipe 4, and then transferred to the spray pipe 6 through the diversion pipe 5, thereby spraying the upper and lower ends of the paper product, which facilitates the flattening of the paper product.

[0027] Spray nozzles are provided on the side of the spray pipe 6, so that the water sprayed through the spray pipe 6 is in the form of mist, thereby avoiding excessive spraying on the top and bottom ends of the paper product, which would affect the quality of the paper product.

[0028] Both the lower roller 10 and the upper roller 17 are equipped with heating wires inside. The heating wires are wound around the inner side of the lower roller 10 and the upper roller 17, so that after spraying the upper and lower ends of the paper product, the lower roller 10 and the upper roller 17 flatten the paper product by activating the heating wires, and the paper product can be dried at the same time.

[0029] Driven shaft 16 passes through adjusting groove 19 and is connected to the output end of hydraulic telescopic assembly 18.

[0030] The pressing unit includes a drive belt assembly 20, which is driven to the outer surface of the rotating shaft 9. The other end of the drive belt assembly 20 is driven to a conveyor belt 21. A hydraulic telescopic assembly 22 is installed on the top of the device housing 1 above the conveyor belt 21. A pressure plate 23 is fixedly connected to the output end of the hydraulic telescopic assembly 22 and located inside the device housing 1. By installing the pressing unit, the paper product is assisted in flattening and transported above the conveyor belt 21. When the rotating shaft 9 is started, the drive belt assembly 20 is driven by the rotating shaft 9, which in turn drives the conveyor belt 21, thereby transporting the flattened paper product above the conveyor belt 21. Then, by activating the hydraulic telescopic assembly 22, the pressure plate 23 is moved downward, allowing the pressure plate 23 to further press the paper product.

[0031] Working principle: For paper products of different thicknesses, first activate the hydraulic telescopic component 18 to push the driven shaft 16 to move the upper pressing roller 17 downward in the adjusting groove 19, adjusting the distance between the upper pressing roller 17 and the lower pressing roller 10; then activate the motor 7, the bevel gear 1 on the output shaft of the motor 7 meshes with the bevel gear 2 on the outer surface of the rotating shaft 9, causing the rotating shaft 9 to rotate, the rotating shaft 9 drives the transmission gear 11 to rotate, and through the connecting gear 12 drives the driven gear 13 to rotate, the driven gear 13 drives the driven shaft 16, and thus the upper pressing roller 17 rotates. The rotation of the upper and lower pressing rollers assists in unfolding the paper product before pressing, improving flatness and avoiding wrinkles. During this process, water in the water tank 3 is transferred to the spray pipe 6 via the transfer pipe 4 and the diversion pipe 5. The spray nozzles on the side of the spray pipe 6 spray water in a mist, spraying the upper and lower ends of the paper product to flatten it and avoid over-spraying, which would affect the quality. The heating wires inside the lower pressing roller 10 and the upper pressing roller 17 are activated after spraying, drying the paper product while it is being flattened. After the shaping is completed, when the rotating shaft 9 is started, it drives the transmission belt assembly 20, which in turn drives the second conveyor belt 21 to start, transporting the paper product that has been flattened and dried with the assistance of the shaping unit to the top of the second conveyor belt 21. Finally, the hydraulic telescopic assembly 22 is activated, which drives the pressure plate 23 to move downward, further pressing the paper product above the second conveyor belt 21.
