Technical Field

[0001] The utility model relates to a pressing device, specifically a paper pressing device for a paper cutting machine. Background Art

[0002] Paper cutting machines are composed of various paper cutting machines such as toilet paper cutting machines, napkin paper cutting machines, tissue paper cutting machines, square paper cutting machines, reel paper cutting machines, hand towel paper cutting machines, facial tissue paper cutting machines, etc. According to different paper products, the corresponding paper cutting machines are different. Therefore, the structures of the corresponding pressing devices of current paper cutting machines are also different, resulting in the non - universality of the pressing devices. For example, the utility model patent CN220197855U discloses an environmental protection paper pressing device for a paper cutting machine, which includes a main body mechanism, a limiting mechanism, and a pressing mechanism. The limiting mechanism is located at the upper end of the main body mechanism, and the pressing mechanism is located at the upper end of the main body mechanism. The main body mechanism includes a placing plate, a fixing plate, main body legs, leg fixing connecting rods, and rotating rollers. The left and right ends of the placing plate are fixedly connected to the fixing plate. The upper ends of the main body legs are fixedly connected to the lower ends of the fixing plate. The leg fixing connecting rods are fixedly connected between the two main body legs. The rotating rollers are rotatably connected to the lower ends of the main body legs. This environmental protection paper pressing device for a paper cutting machine, through the structure of the limiting mechanism, facilitates the fixing of papers with different widths during actual use. However, due to pulp reasons, there are local thickness differences in the same piece of paper at present. Especially when the paper is relatively thick, when a stack of papers is pressed, the edges or one side are very likely not to be compacted, which makes it difficult to completely press the entire stack of papers. There is an urgent need to improve the above - mentioned problems. Summary of the Utility Model

[0003] To solve the above problems, the purpose of the utility model is to provide a paper pressing device for a paper cutting machine.

[0004] To achieve the above purpose, the technical solution of the utility model is: a paper pressing device for a paper cutting machine, which includes a base and vertical arms on both sides at the rear of the base. A horizontal top plate is fixed at the top of the arms. A main cylinder is fixed at the center of the bottom surface of the top plate. The lower telescopic end of the main cylinder is fixed with a horizontal push - pressure plate. The lower surface of the push - pressure plate is fixed with a flat pressing plate through multiple vertical sealed telescopic rods. The lower surface of each pressing plate is fixedly connected to a rubber pressing plate respectively. Each sealed telescopic rod is communicated with a three - way solenoid valve of an air - inflation pump fixed at the rear of the base through a connecting pipe. The main cylinder is communicated with the air - inflation pump through a control valve.

[0005] Further, a plurality of legs support the base below.

[0006] Further, a horizontal tabletop is fixed on the surface of the base below the pressing plate, and a layer of rubber pad is laid on the tabletop.

[0007] Furthermore, a switch module for controlling the lifting and lowering of the main cylinder and the extension and retraction of each enclosed telescopic rod is located on one side of the top plate.

[0008] Furthermore, the top plate is an E-shaped structure, and vertical guide rods are passed through both sides of the top plate, and the lower end of each guide rod is fixedly connected to the upper surface of each end of the push plate.

[0009] Furthermore, the top plate is an E-shaped structure, and the side plates of the top plate are reinforced and connected to the main plate by a reinforcing plate with vertical surfaces.

[0010] The utility model has the functions of buffering and uniform squeezing. When squeezing, the paper to be squeezed is placed on the rubber pad, the main cylinder extends, but the rubber pressing plate does not contact the paper, the air pump works to inflate each closed telescopic rod, the closed telescopic rod forms an air spring structure, the main cylinder continues to extend, so that the rubber pressing plate contacts the paper, because the air pressure in each closed telescopic rod is consistent, and each closed telescopic rod corresponds to a pressing plate, the pressing force of each pressing plate on the paper is consistent through air pressure balancing, so that it fully contacts the paper, prevents uneven pressing force on the paper, achieves a better pressing effect, and is convenient for pressing the paper, thereby ensuring the quality of paper cutting.

[0016] The following describes this embodiment in detail with reference to the accompanying drawings:

[0017] This embodiment provides a paper pressing device for a paper cutting machine. Please also refer to the Figures 1 - 3 .

[0018] As Figures 1 - 3 shown, a paper pressing device for a paper cutting machine includes a base 1 and vertical support arms 2 on both sides at the rear of the base 1. A horizontal top plate 3 is fixed to the top of the support arms 2. A main cylinder 4 is fixed to the center of the bottom surface of the top plate 3. The lower telescopic end of the main cylinder 4 is fixed with a horizontal push plate 5. The lower surface of the push plate 5 is fixed with a flat pressing plate 7 through a plurality of vertical sealed telescopic rods 6. The lower surface of each pressing plate 7 is fixedly connected to a rubber pressing plate 8 respectively. Each sealed telescopic rod 6 is communicated with a three-way solenoid valve 10 of an air inflation pump 9 fixed to the rear of the base 1 through a communication pipeline. The main cylinder 4 is communicated with the air inflation pump 9 through a control valve.

[0019] A plurality of legs 11 support the base 1. A horizontal table surface 12 is fixed to the surface of the base 1 below the pressing plate 7. A rubber pad 13 is laid on the table surface 12. A switch module 14 for controlling the lifting of the main cylinder 4 and the telescoping of each sealed telescopic rod 6 is located on one side of the top plate 3. The top plate 3 is of an E-shaped structure, and vertical guide rods 15 penetrate through both sides of the top plate 3. The lower end of each guide rod 15 is fixedly connected to the upper surface of each end of the push plate 5. The top plate 3 is of an E-shaped structure, and the side plate and the main board of the top plate 3 are strengthened and connected through a vertical reinforcing plate 16 on the surface.

[0020] Working principle of the utility model: The utility model can be arranged on both sides of the paper cutter respectively. The upper surface of the tabletop 12 is kept horizontal with the cutting tabletop of the paper cutter. When cutting is required, when pressing on both sides, place the paper on the rubber pad 13. The main cylinder 4 extends, but the pressing plate 7 does not contact the paper. The air pump 10 works to inflate the sealed telescopic rod 6, and the sealed telescopic rod 6 forms an air spring structure. The main cylinder 4 continues to extend, so that the pressing plate 7 contacts the paper. Since the air pressure in the sealed telescopic rod 6 is consistent, the extrusion force of the pressing plate 7 on the paper at each place is consistent, so as to fully contact the paper, prevent uneven force on the paper, especially at the four corners, and achieve a better pressing effect. After pressing, the paper between the two pressing devices is fully tightened and flattened. Since the paper on both sides of the paper cutter is evenly and firmly pressed, when the paper cutter cuts, the paper on both sides of the cutting part will not loosen, slip or displace, which is convenient for the paper cutter to cut and achieves a better paper cutting and trimming effect.

[0021] Certainly, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
