Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper processing technology, specifically to a paper pushing pre-push pressure adjustment. Background Technology
[0002] In the fields of paper processing, printing, and packaging production, paper pushing equipment is one of the core devices for achieving automated paper transport and positioning. This type of equipment needs to push stacks of paper to subsequent processes, such as cutting, printing, or folding stations, according to a specific rhythm and position, to ensure the continuity and automation of the entire production process. It is an important basic piece of equipment in modern paper processing production lines for improving efficiency and reducing manual intervention.
[0003] Because the paper materials (such as thin paper, cardboard, kraft paper) and thicknesses involved in the processing vary greatly, and different processes have different requirements for paper pushing force, the paper pushing pre-push pressure needs to be flexibly adjusted according to the actual working conditions. Currently, when adjusting the pre-push pressure of paper pushing equipment, operators can only rely on experience to judge the pressure, such as by observing the state of the paper being pushed or by turning the adjustment parts by hand to estimate the pressure. They cannot accurately know the specific pressure value at present. This adjustment method is not only inefficient, but also prone to deviations: if the pressure is too high, it may cause thin paper to wrinkle, thick paper to be damaged at the edges, or even cause additional wear and tear on the pushing parts of the equipment; if the pressure is too low, the paper may not be pushed in place or may be misaligned, which will lead to errors in subsequent processing and require frequent machine stops for readjustment. This not only affects the production schedule, but also increases paper waste and labor costs. Utility Model Content
[0004] The purpose of this invention is to provide a paper-pushing pre-push pressure adjustment method to solve the problem mentioned in the background art that the pressure adjustment can only rely on experience.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A paper pusher pre-push pressure adjustment includes a paper pusher cylinder air inlet pipe and a rectangular box. The paper pusher cylinder air inlet pipe includes an air inlet regulating valve. A pointer is provided on one side of the air inlet regulating valve. An adjustment component is provided on one side of the rectangular box. The adjustment assembly includes a rotating groove, inside which a rotating component is rotatably disposed, a first gear is disposed in front of the rotating component, and a gear groove is disposed at the rear of the rotating groove.
[0006] In a preferred embodiment of this utility model, the rectangular box is fixedly installed on the outside of the air inlet pipe of the paper pusher cylinder, and the outside of the air inlet regulating valve is located in front of the rectangular box.
[0007] In a preferred embodiment of this utility model, a fan-shaped scale line is provided in front of the rectangular box, and the outer side of the pointer points to different fan-shaped scale lines.
[0008] In a preferred embodiment of this utility model, the outer side of the intake regulating valve is provided with sector teeth, and the first gear meshes with the sector teeth.
[0009] In a preferred embodiment of this utility model, a hexagonal groove is provided on the inner side of the rotating component, and a hexagonal block is slidably disposed inside the hexagonal groove.
[0010] In a preferred embodiment of the present invention, a second gear is provided behind the hexagonal block, and the second gear is disassembled and assembled in a gear groove.
[0011] In a preferred embodiment of this utility model, a spring is provided at the front of the hexagonal slot, and a hexagonal block is connected to the rear of the spring.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0014] Beneficial effects: By pulling the hexagonal block with the lever, the second gear is disassembled in the gear slot. At this time, the first gear can be rotated. By rotating the first gear, the sector teeth and the air intake regulating valve are rotated, thereby adjusting the air intake and thus the pushing force of the paper. When the sector teeth move one tooth distance, the pointer points to a different sector scale line, so that the staff can accurately know the specific value of the current paper pushing pressure and avoid blind adjustment. After the adjustment is completed, the hexagonal block is pushed by the spring, so that the second gear is inserted into the gear slot. At this time, the first gear and sector teeth cannot be rotated by the limit of the second gear and the hexagonal block, thus fixing the air intake regulating valve.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] Please refer to Figures 1-4 This utility model discloses a paper-pushing pre-push pressure adjustment, including a paper-pushing cylinder air inlet pipe 1 and a rectangular box 2. The paper-pushing cylinder air inlet pipe 1 is the air inlet pipe of the cylinder used in the paper-pushing device. This section of the air inlet pipe is a rigid pipe, that is, by making a section of a conventional flexible air inlet pipe rigid, and installing a valve and a rectangular box 2, etc. The two ends of the air inlet pipe can still adopt conventional design, connecting the paper-pushing cylinder and the air supply structure respectively. The rectangular box 2 is an installation structure, which is fixedly installed on the outside of the paper-pushing cylinder air inlet pipe 1. The paper-pushing cylinder air inlet pipe 1 includes an air inlet regulating valve 11. The outside of the air inlet regulating valve 11 is located in front of the rectangular box 2. By rotating the air inlet regulating valve 11, the air intake is adjusted, thereby adjusting the paper-pushing force. The air inlet regulating valve 11 can be a QTY series pneumatic flow regulating valve, and the structure on the outside of the valve stem is fixedly installed by welding or other existing methods, which is a conventional technical means for those skilled in the art.
[0020] An adjustment assembly is provided on one side of the rectangular box 2. The adjustment assembly includes a rotating groove 21, inside which a rotating component 22 is rotatably mounted. A first gear 23 is positioned in front of the rotating component 22. A sector tooth 12 is positioned on the outside of the air intake regulating valve 11. The first gear 23 meshes with the sector tooth 12. That is, by rotating the first gear 23, the sector tooth 12 and the air intake regulating valve 11 are driven to rotate. A pointer 13 is positioned on one side in front of the air intake regulating valve 11, and a sector scale line 14 is positioned in front of the rectangular box 2. When the air intake regulating valve 11 rotates, the outside of the pointer 13 points to different sector scale lines 14. That is, different scale lines represent different air intake volumes and paper pushing pressures. When the sector tooth 12 moves one tooth distance, the pointer 13 points to different sector scale lines 14, so that the staff can accurately know the specific value of the current paper pushing pre-push pressure and avoid blind adjustment.
[0021] A gear groove 24 is provided at the rear of the rotating slot 21. A hexagonal groove 3 is provided on the inner side of the rotating part 22. A hexagonal block 31 is slidably arranged inside the hexagonal groove 3. A second gear 33 is fixedly arranged behind the hexagonal block 31. The second gear 33 has the same number of teeth and model as the first gear 23, only different in size. The second gear 33 is installed and removed in the gear groove 24, and it can be inserted into the gear groove 24 every time it rotates one tooth. A spring 32 is provided at the front of the hexagonal groove 3, and the hexagonal block 31 is connected behind the spring 32. 32 continuously pushes the hexagonal block 31, causing the second gear 33 to insert into the gear groove 24. At this time, the first gear 23 and the sector tooth 12 cannot rotate due to the limiting effect of the second gear 33 and the hexagonal block 31, thereby fixing the intake regulating valve 11. A pull rod 34 is provided behind the hexagonal block 31. The pull rod 34 extends to the front of the outside of the first gear 23. The hexagonal block 31 can be pulled by the pull rod 34 to disassemble the second gear 33 in the gear groove 24. At this time, the first gear 23 can be rotated.
[0022] The working principle of this utility model is as follows: By pulling the hexagonal block 31 with the pull rod 34, the second gear 33 is disassembled in the gear groove 24. At this time, the first gear 23 can be rotated. By rotating the first gear 23, the sector tooth 12 and the air intake regulating valve 11 are rotated, thereby adjusting the air intake and thus adjusting the pushing force of the paper. When the sector tooth 12 moves a distance of one tooth, the pointer 13 points to a different sector scale line 14, so that the operator can accurately know the specific value of the current paper pushing pressure and avoid blind adjustment. After the adjustment is completed, the hexagonal block 31 is pushed by the spring 32, so that the second gear 33 is inserted into the gear groove 24. At this time, the first gear 23 and the sector tooth 12 cannot be rotated by the second gear 33 and the hexagonal block 31, thereby fixing the air intake regulating valve 11.
[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
