Description

Technical Field

[0001] This utility model belongs to the field of paper product processing technology, and in particular relates to a pressing device for paper product processing. Background Technology

[0002] Paper product processing is the process of using various types of pulp, paper, or paperboard as raw materials and employing a series of physical, chemical, or printing processes to create products with specific shapes, functions, or decorative effects. In paper product processing, lamination is a crucial step, using pressure to tightly bond two or more layers of material together to form a final product with desired properties. Lamination is widely used in the production of various paper products and is a key step in achieving lamination, molding, surface decoration, and enhanced functionality.

[0003] A search revealed a paper pressing machine for paper product processing, with publication number CN218399662U, published on the Chinese Patent website. This pressing machine can press paper products through a pressure roller structure, but it has some defects and shortcomings that need to be improved: (1) Traditional pressure roller structures mostly rely on line contact when pressing paper products. The pressure roller structure is prone to displacement due to mechanical vibration or wear. In addition, the paper products are also prone to displacement due to force during the pressing process, resulting in uneven pressure distribution, which in turn leads to local incomplete pressing, air bubbles or wrinkles in the paper products, thus affecting the quality of the finished product; (2) Due to structural design reasons, some existing pressing devices are difficult to effectively clean the solid particulate impurities such as dust remaining on the surface of the paper products before pressing. This causes these impurities to adhere tightly to the paper products after pressing, thus affecting the aesthetics of the finished product. Therefore, in view of the above problems, the pressing device for paper product processing provided by this utility model is of great significance. Utility Model Content

[0033] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Please see Figure 1-10 As shown, a pressing device for paper product processing according to the present invention includes a worktable 1. Several support legs 2 are fixedly connected to the bottom of the worktable 1, and a fixed frame 3 and a pair of guide rails 4 are fixedly connected to the top of the worktable 1. The pair of guide rails 4 are located on the front side of the fixed frame 3, and an adjustment groove 5 is opened on the top of the fixed frame 3. A positioning component is provided between the pair of guide rails 4. The side of the fixed frame 3 is L-shaped, and a pressing mechanism is provided on the top of the fixed frame 3. A cleaning mechanism is provided on the side of the fixed frame 3.

[0036] The positioning assembly includes a pair of movable seats 6, with L-shaped ends. Each end of the movable seat 6 is fixedly connected to a first stud 7, and a first nut 8 is threaded onto the first stud 7 to cooperate with it. An electric telescopic rod 9 is installed on the top of the movable seat 6, and a positioning plate 10 is fixedly connected to the bottom of the output shaft of the electric telescopic rod 9. When a paper product coated with adhesive is placed on the worktable 1, the electric telescopic rod 9 can be driven to move the positioning plate 10 downward until the positioning plate 10 is attached to the top of the paper product. At this time, the pressure applied by the positioning plate 10 can firmly fix the paper product on the worktable 1 to play a positioning role, thereby preventing the paper product from shifting due to force during the pressing process.

[0037] The pressing mechanism includes a cylinder 11, which is mounted on the top of the fixed frame 3. A heating chamber 12 is fixedly connected to the bottom end of the cylinder's output shaft. The heating chamber 12 has a hollow interior, with several positioning holes 13 protruding outwards from its bottom edge. A power supply base 14 is installed on the inner wall of the heating chamber 12, and several heating tubes 15 are electrically connected to the power supply base 14. A pressing plate 16 is installed at the bottom of the heating chamber 12. The pressing plate 16 has a hollow interior, with several heat-conducting holes 17 on its top. Several second studs 18 are fixedly connected to the top of both ends of the pressing plate 16, and second nuts 19 are threaded onto the second studs 18. The cylinder 11 is connected to a matching air source system, which drives the cylinder 11 to move the heating chamber 12 and the pressing plate 16 downwards until they are pressed together. The plate 16 is attached to the top of the paper product. At this time, the pressure applied by the pressing plate 16 can press the paper product. Compared with the line contact of the pressure roller structure, the paper product can be subjected to more sufficient and uniform force, thereby effectively avoiding the occurrence of local incomplete pressing, air bubbles or wrinkles in the paper product, which will affect the quality of the finished product. The power supply base 14 has a built-in battery, which can supply power to the heating tube 15. After the heating tube 15 is powered on, it can generate heat. The heat can enter the inner cavity of the pressing plate 16 through each heat conduction hole 17 to heat the pressing plate 16. When the paper product is pressed by the pressure of the pressing plate 16, this heat can be transferred to the surface of the paper product to heat the adhesive applied between the paper products. This allows the adhesive to penetrate into the pressing surface of the paper product more quickly after being heated, thereby making the pressing of the paper product tighter.

[0038] The cleaning mechanism includes an exhaust fan 20 and a cleaning chamber 21. The exhaust fan 20 is installed on the rear end face of the fixed frame 3, and exhaust pipes 22 are installed on both sides of the exhaust fan 20. Several connecting blocks 23 are fixedly connected between the cleaning chamber 21 and the front end face of the fixed frame 3. The cleaning chamber 21 has a hollow internal structure, and several suction pipes 24 are opened on the front end face of the cleaning chamber 21. The other end of the exhaust pipe 22 passes through the rear end face of the cleaning chamber 21 and communicates with the inner cavity of the cleaning chamber 21. A suction port 25 is opened on the top of the cleaning chamber 21, and a suction plate 26 is inserted into the suction port 25. A suction net 27 is installed on the suction plate 26. A fixing block 28 is fixedly connected to the top of 6, and a handle 29 is fixedly connected to the fixing block 28. Before pressing the paper product, the exhaust fan 20 can be driven to draw air into the cleaning chamber 21 through the exhaust pipe 22. After the cleaning chamber 21 generates negative pressure, the dust and other solid particles and impurities remaining on the surface of the paper product can be sucked into the cleaning chamber 21 through each suction pipe 24. After the impurities enter the cleaning chamber 21, they will come into contact with the suction net 27. At this time, the suction net 27 can adsorb the impurities, thereby achieving effective cleaning of the impurities and preventing the impurities from being tightly attached to the paper product after pressing, thus affecting the appearance of the finished product.

[0039] The guide rail 4 has an L-shaped side, and its inner wall height and spacing are equal to the thickness and length of the two ends of the movable seat 6, respectively. The adjustment groove 5 is rectangular, and its width is equal to the diameter of the first stud 7. Each first stud 7 passes through the corresponding adjustment groove 5. The movable seat 6 can drive the first stud 7 to move horizontally along the adjustment groove 5 so as to adjust the position of the positioning component according to the length of the paper product, thereby ensuring that the positioning component is located directly above both ends of the paper product. After the position adjustment is completed, the first nut 8 is threaded onto each first stud 7 and tightened to fix the position of the positioning component.

[0040] The bottom surface of the positioning plate 10 is provided with an anti-slip pad 30. The surface of the anti-slip pad 30 is provided with herringbone anti-slip texture. The anti-slip pad 30 can be made of elastic materials such as rubber and is fixed by adhesives. When the positioning plate 10 is attached to the top of the paper product, the anti-slip texture on the surface of the anti-slip pad 30 can increase the friction between the paper product and the positioning plate 10, so as to play an anti-slip role and thus effectively enhance the positioning effect of the positioning component.

[0041] The heat conduction holes 17 are arranged in a linear array along the top surface of the pressing plate 16, and each heat conduction hole 17 is located inside the heating chamber 12. A protective pad 31 is provided on the bottom surface of the pressing plate 16. The protective pad 31 can be made of elastic materials such as sponge and is fixed by adhesives. When the pressing plate 16 is attached to the top of the paper product, the protective pad 31 can play a flexible protection role to avoid the pressure applied by the pressing plate 16 from directly acting on the surface of the paper product and causing damage to the paper product.

[0042] The number of second studs 18 is the same as that of the positioning holes 13, and their diameters correspond to the diameters of the positioning holes 13. The center of each second stud 18 corresponds one-to-one with the center of each positioning hole 13. Each second stud 18 can be aligned and pass through the corresponding positioning hole 13. At this time, the second nut 19 is threaded onto each second stud 18 and tightened. The pressing plate 16 can be fixed to the bottom of the heating chamber 12 through the mutual cooperation between the second studs 18, the positioning holes 13, and the second nut 19. The pressing plate 16 can be removed from the bottom of the heating chamber 12 by unscrewing the second nut 19, so that the power supply base 14 and the heating tube 15 inside the heating chamber 12 can be regularly maintained and replaced.

[0043] The suction pipes 24 are connected to the inner cavity of the cleaning chamber 21 and are distributed linearly at equal intervals along the length of the cleaning chamber 21. The height of each suction pipe 24 is the same and located above the guide rail 4. The coverage of the cleaning mechanism can be expanded by multiple suction pipes 24 to ensure that impurities can be fully sucked into the cleaning chamber 21 from multiple angles during cleaning, thereby avoiding residue.

[0044] Both the suction port 25 and the suction plate 26 are rectangular, with their length and width corresponding to the length and thickness of the suction plate 26, respectively. The width of the suction plate 26 corresponds to the height of the inner wall of the cleaning chamber 21. The fixing block 28 is long and narrow, with its length and width greater than the length and width of the suction port 25, respectively. The fixing block 28 can be attached to the top of the cleaning chamber 21 by holding the handle 29. At this time, the suction plate 26 can be inserted into and attached to the inner wall of the cleaning chamber 21 to play a limiting role, thereby preventing the suction plate 26 from shifting or loosening. After long-term use, the suction plate 26 can be pulled out of the cleaning chamber 21 by holding the handle 29 for regular cleaning of the suction net 27.

[0045] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0046] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0047] The working principle of this utility model is as follows:

[0048] In use, the paper product coated with adhesive can be placed on the workbench 1. The position of the positioning components is then adjusted according to the length of the paper product until they are directly above both ends. The electric telescopic rod 9 is then driven to move the positioning plate 10 downwards until it adheres to the top of the paper product. The pressure applied by the positioning plate 10 firmly fixes the paper product to the workbench 1, thus achieving the positioning function. Next, the exhaust fan 20 is driven to draw air from the cleaning chamber 21 through the exhaust pipe 22. After negative pressure is generated in the cleaning chamber 21, dust and other solid particles remaining on the surface of the paper product are sucked into the cleaning chamber 21 through the suction pipes 24. Once inside the cleaning chamber 21, the impurities come into contact with the suction net 27, which adsorbs the impurities, thus effectively cleaning them. Finally, the cylinder 11 is driven by the air source system. This causes the heating chamber 12 and the pressing plate 16 to move downwards together until the pressing plate 16 is attached to the top of the paper product. At this time, the pressure applied by the pressing plate 16 can press the paper product. Compared with the line contact of the pressure roller structure, the paper product can be subjected to more sufficient and uniform force, thereby effectively avoiding the occurrence of local incomplete pressing, air bubbles or wrinkles in the paper product, which would affect the quality of the finished product. The power supply base 14 has a built-in battery that can supply power to the heating tube 15. After the heating tube 15 is powered on, it can generate heat. The heat can enter the inner cavity of the pressing plate 16 through the heat conduction holes 17 to heat the pressing plate 16. When the paper product is pressed by the pressure of the pressing plate 16, this heat can be transferred to the surface of the paper product to heat the adhesive applied between the paper products. This allows the adhesive to penetrate into the pressing surface of the paper product more quickly after being heated, thereby making the paper product more tightly pressed.
