[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1 Reference Figures 1-5 A pressing device includes: a worktable 1, with two mutually abutting conveyor rollers 3 on the top of the worktable 1. These two conveyor rollers 3 can be driven to rotate by an external motor for conveying paper. A material platform 2 is provided on one side of the worktable 1 for placing the paper to be processed, facilitating the feeding of the paper between the conveyor rollers 3.

[0017] Multiple lower pressure strips 4 are fixedly installed on the top of the workbench 1, and these lower pressure strips 4 are arranged parallel to the length of the workbench 1. A fixing plate 5 is fixedly installed on one side of the workbench 1, and a first electric push rod 11 is fixedly installed through the top of the fixing plate 5. A first connecting plate 7 is fixedly installed at the output end of the first electric push rod 11. Multiple upper pressure strips 9 are provided at the bottom of the first connecting plate 7 to cooperate with the lower pressure strips 4. These upper pressure strips 9 correspond one-to-one with the lower pressure strips 4, and a pressure groove 10 is left between two adjacent upper pressure strips 9 and two lower pressure strips 4. These pressure grooves 10 are used to fold the paper.

[0018] A drive mechanism is provided to sequentially lower the upper pressure bar 9. The drive mechanism includes two first guide rods 6 that slide through the top of the first connecting plate 7. These two first guide rods 6 are also slidably mounted on the fixed plate 5, serving to guide and support the first connecting plate 7. The bottom ends of the two first guide rods 6 are fixedly mounted on the same mounting plate 8. Multiple sets of fourth guide rods 23 corresponding to the upper pressure bar 9 are slidably mounted on the top of the mounting plate 8. The upper pressure bar 9 is fixedly connected to the corresponding fourth guide rod 23. A connecting rod 25 is fixedly mounted between each set of fourth guide rods 23. An extension plate 19 is fixedly mounted on one side of the mounting plate 8. A mounting seat 18 is fixedly mounted on the top of the extension plate 19. A second electric push rod 20 is fixedly mounted through one side of the mounting seat 18. A wedge 22, which cooperates with the connecting rod 25, is fixedly mounted at the output end of the second electric push rod 20. When the second electric push rod 20 operates, it can push the wedge 22 to move left and right. Due to the inclined design of the wedge 22, it can sequentially push the connecting rod 25 downwards, thereby lowering the upper pressure bar 9 and folding the paper.

[0019] A pressing mechanism is provided to collect folded paper. The pressing mechanism includes a collection box 12 fixedly mounted on one side of the workbench 1. Two second guide rods slidably extend through one side of the collection box 12, and one end of each second guide rod 14 is fixedly connected to a push plate 13 located inside the collection box 12. Springs 15 are fitted onto the outer walls of the second guide rods 14, and the two ends of the springs 15 are fixedly connected to the inner wall of one side of the collection box 12 and one side of the push plate 13, respectively. When folded paper falls into the collection box 12, it pushes the push plate 13 to move, compressing the springs 15. Simultaneously, two feeding rollers 16 are rotatably mounted inside the collection box 12 for feeding paper. A motor 17 corresponding to the feeding rollers 16 is fixedly mounted on the top of the collection box 12, and the output end of the motor 17 is fixedly connected to the feeding rollers 16. When the motor 17 operates, it drives the feeding rollers 16 to rotate, feeding the paper to the outlet of the collection box 12.

[0020] This application can be used in the field of paper processing, or in other fields applicable to this application.

[0021] Example 2 refer to Figures 1-5 Based on Example 1, an improvement is made to a pressing device for efficient molding of paper-plastic decorative items, which is applied to the paper processing field. In order to drive the upper pressing bar 9 to reset and move, the same first tension spring 24 is fixed between the top of the fourth guide rod 23 and the first connecting plate 7. When the second electric push rod 20 stops working, the first tension spring 24 can pull the fourth guide rod 23 and the connecting rod 25 to reset, thereby driving the upper pressing bar 9 to reset.

[0022] To guide the wedge 22, a third guide rod 21 is slidably provided through one side of the mounting base 18, and one end of the third guide rod 21 is fixedly connected to the wedge 22. At the same time, the distance between the bottom of the wedge 22 and the mounting plate 8 is greater than the diameter of the connecting rod 25, ensuring that the wedge 22 can smoothly push the connecting rod 25 down.

[0023] To push out the folded paper, multiple lifting bars 26 are slidably installed through the top of the worktable 1, located between two adjacent lower pressure bars 4. The bottom of the multiple lifting bars 26 is fixedly fitted with a second connecting plate 27 located within the worktable 1. Two fifth guide rods 28 are slidably installed through the bottom of the worktable 1, and second tension springs 29 are sleeved on the outer walls of the fifth guide rods 28. The two ends of the second tension springs 29 are fixedly connected to the bottom of the worktable 1 and the outer walls of the second tension springs 29, respectively. When the upper pressure bar 9 returns to its original position, the second tension springs 29 can drive the second connecting plate 27 to move upward, causing the lifting bars 26 to rise and push the paper out of the pressure groove 10.

[0024] In this application, firstly, the cardboard is placed on the material table 2. Then, the motor 17 on one side of the workbench 1 is started to drive the conveyor roller 3 to rotate, while simultaneously pushing the cardboard between the two conveyor rollers 3. When the cardboard contacts the two conveyor rollers 3, it can be conveyed to the downward pressure strip 4 by the friction of the two conveyor rollers 3. After being conveyed to the correct position, the first electric push rod 11 is activated to extend, which can drive the first connecting plate 7 to move downward. The downward movement of the first connecting plate 7 can drive the mounting plate 8 to move downward through the first guide rod 6, which can drive multiple upper pressure strips 9 to move downward until the upper pressure strips 9 are close to the paper. Then, the second electric push rod 20 is activated to extend. During the extension of the second electric push rod 20, it can drive the wedge block 22 to move. When the wedge 22 contacts the first connecting rod 25, it can drive the connecting rod 25 to move downward. The movement of the connecting rod 25 can drive the two connecting rods 25 to move downward, thereby driving the upper pressure bar 9 to move downward. When the upper pressure bar 9 moves between the two lower pressure bars 4, it can drive the lifting bar 26 to move downward. The downward movement of the lifting bar 26 can drive the fifth guide rod 28 to move downward through the second connecting plate 27 and stretch the second tension spring 29. At the same time, it can fold the cardboard through the gap between the upper pressure bar 9 and the two lower pressure bars 4. Continue to start the second electric push rod 20 to extend and drive the corresponding upper pressure bar 9 to move downward through the wedge 22 in sequence, folding the cardboard in sequence. At the same time, continue to start the conveyor roller 3 to convey the cardboard. Once all the upper pressure bars 9 are fully in place, the second electric push rod 20 is activated to retract, which can drive the wedge block 22 to reset and move. The fourth guide rod 23 can reset and move upward under the force of the corresponding first tension spring 24, and drive the upper pressure bars 9 away from the lower pressure bars 4. At the same time, the lifting bar 26 can move upward under the force of the second tension spring 29, pushing the folded paper in the multiple lower pressure bars 4 upward. Then, the motor 17 is activated to drive the conveying roller 3 to rotate and convey the paper. The folded paper can move towards the collection box 12. At the same time, the motor 17 is activated to drive the feeding roller 16 to rotate. When the folded paper contacts the feeding roller 16, it can be fed into the collection box 12 by the feeding roller 16. The push plate 13 presses the folded paper. When there is a lot of paper, it will squeeze the push plate 13, causing the push plate 13 to move in the collection box 12 to compress the spring 15. Finally, the pressed papers in collection box 12 are removed manually.

[0025] However, as is well known to those skilled in the art, the working principles and wiring methods of the first electric actuator 11, the motor 17, and the second electric actuator 20 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
