Description

Technical Field

[0001] This utility model relates to the technical field of paper cup production equipment, and in particular to a positioning device for printing in paper cup production. Background Technology

[0002] The patterns on the surface of common paper cups are usually printed using printing equipment. During the printing process, positioning devices are needed to fix the position of the paper cup during printing. As consumers' requirements for the appearance design of paper cups increase and the market demand for diversified and personalized paper cups continues to grow, the precision and quality of paper cup printing have become key factors in determining product competitiveness. Precise positioning devices can ensure that the printed pattern is accurately printed on the surface of the paper cup, avoiding the increase in defect rate caused by printing deviation, thereby improving production efficiency and reducing production costs. Moreover, in the process of large-scale production, fast and stable positioning function is of great significance for improving the continuity and capacity of the production line. Existing positioning devices for paper cup production and printing have a variety of mechanical structures and technical principles. Some positioning devices adopt a simple mechanical clamp structure, which is adapted to different sizes of paper cups by manually adjusting the position of the clamp. This method mainly relies on the operator's experience and uses the physical contact between the mechanical clamp and the paper cup for positioning. However, existing technologies have a prominent problem: the positioning devices have limitations in height adjustment. In the actual paper cup production and printing process, the heights of different types and specifications of paper cups vary greatly. Existing positioning devices often struggle to achieve quick, accurate, and convenient height adjustment when faced with height changes. For example, traditional positioning devices require cumbersome manual disassembly and reassembly of components to adjust to the appropriate height to accommodate paper cups of different heights. This not only consumes a lot of time but is also prone to inaccurate positioning due to improper operation, seriously affecting production efficiency and printing quality. It cannot meet the demands of the modern paper cup production and printing industry for efficient and precise production. Therefore, a mixing device for construction engineering is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a positioning device for paper cup production and printing, which aims to improve the problem that the position of the roller in traditional equipment is relatively fixed and it is difficult to make targeted adjustments for different paper cup diameters.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for printing in paper cup production, comprising a fixed plate, a protective shell fixedly connected to the top of the fixed plate, fixed frames fixedly connected to both sides of the fixed plate, a sliding column fixedly connected between the two fixed frames, a plurality of movable blocks slidably connected to the outer wall of the sliding column, a second roller provided on the top of each movable block, a width adjustment component provided on the outer wall of the movable block, and a height adjustment component provided on the top of the second roller; The width adjustment assembly includes two symmetrically distributed inclined guide grooves located on one side of the moving block. The outer wall of the protective shell is provided with a sliding plate, and both sides of the inner side of the sliding plate are fixed to the outer wall of the guide groove. Nuts are fixedly connected to the side walls of the sliding plate, and threaded rods are rotatably connected to the inner walls of the nuts. A knob is fixedly connected to the top of the threaded rod. A sliding column is fixedly connected to one side of each moving block, and the outer wall of each sliding column is slidably connected to the inner wall of the guide groove.

[0005] As a further description of the above technical solution: The height adjustment assembly includes a limiting post one, which is located at the top of the moving block. The bottom of the threaded rod is rotatably connected to the inside of the protective shell. A sleeve is slidably connected to the outer wall of the limiting post one, and a rotating post two is slidably connected to the inner wall of the limiting post one.

[0006] As a further description of the above technical solution: Both ends of the rotating column are fixedly connected to limit columns, and each of the multiple limit columns is fixedly connected to a push block on one side.

[0007] As a further description of the above technical solution: The push block is rotatably connected to a rotating column, and both ends of the rotating column are fixedly connected to a fixing block. The outer walls of the fixing blocks on both sides are fixedly connected to the side walls of the sleeve.

[0008] As a further description of the above technical solution: A spring is provided on one side of the pressing block. One end of the spring is fixedly connected to the outer wall of the pressing block, and the other end of the spring is fixedly connected to the outer wall of the sleeve.

[0009] As a further description of the above technical solution: The inner wall of the sleeve is rotatably connected to a cylinder, and each of the rollers is rotatably connected to a cylinder.

[0010] As a further description of the above technical solution: The bottom end of each of the two cylinders is rotatably connected to the inside of the moving block, and the top of each of the two cylinders is fixedly connected to a cylinder, and the bottom of the sleeve is fixedly connected to a roller.

[0011] As a further description of the above technical solution: The outer wall of the first cylinder is rotatably connected to the inner walls of the second roller, the first roller, and the sleeve from bottom to top. The inner wall of the first cylinder has multiple grooves, which engage with the first limiting post.

[0012] This utility model has the following beneficial effects: In this invention, the screw rod is rotated by a knob to drive the nut and the slide plate to slide up and down. As the slide plate moves, it drives the moving block at one end of the sliding column to slide in the opposite direction on the outer wall of the sliding column through the guide grooves on both sides. This achieves the purpose of adjusting the distance between the two rollers on both sides, solving the problem that the position of the two rollers in traditional equipment is relatively fixed and it is difficult to make targeted adjustments for different paper cup diameters, thus enhancing the practicality of the equipment.

This solves the problem that the positioning height of traditional devices is relatively fixed and it is difficult to make targeted adjustments according to paper cups of different heights, thus enhancing the applicability of the equipment.

[0016] 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.

[0017] Reference Figure 1 - Figure 3 An embodiment of this utility model includes a fixed plate 21, a protective shell 22 fixedly connected to the top of the fixed plate 21, the protective shell 22 being used to protect the internal structure from the influence of the external environment, fixed frames 6 fixedly connected to both sides of the fixed plate 21, the fixed frames 6 being used to enhance the stability of the overall structure, a sliding column 5 fixedly connected between the two fixed frames 6, a plurality of moving blocks 8 slidably connected to the outer wall of the sliding column 5, a roller 23 being provided on the top of each moving block 8, the roller 23 being used to support and guide the moving parts, a width adjustment component being provided on the outer wall of the moving block 8, and a height adjustment component being provided on the top of the roller 23; The width adjustment assembly includes two symmetrically distributed inclined guide grooves 11, which are located on one side of the moving block 8. The guide grooves 11 are used to guide the sliding direction of the moving block 8. The outer wall of the protective shell 22 is provided with a sliding plate 19. Both sides of the inner side of the sliding plate 19 are fixed to the outer wall of the guide groove 11. Nuts 12 are fixedly connected to the side wall of the sliding plate 19. Threaded rods 10 are threadedly connected to the inner wall of the nut 12. A knob 9 is fixedly connected to the top of the threaded rod 10. The knob 9 is used to manually adjust the width. A sliding column 13 is fixedly connected to one side of each moving block 8. Sliding columns 5 are slidably connected to the inner wall of multiple moving blocks 8. The outer wall of each sliding column 13 is slidably connected to the inner wall of the guide groove 11. The sliding column 13 is used to ensure the smooth sliding of the moving block 8 in the guide groove 11.

[0018] Specifically, during the paper cup production positioning process, the operator drives the threaded rod 10 to rotate by rotating the knob 9. The knob 9 is used for manual operation to drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 causes the nut 12 to move up and down along the axial direction of the threaded rod 10. The nut 12 is used to convert the rotational motion of the threaded rod 10 into linear motion. The movement of the nut 12 simultaneously drives the sliding plate 19 to move. The sliding plate 19 is used to connect the nut 12 and the guide groove 11 to transmit motion. The movement of the sliding plate 19 drives the symmetrically distributed inclined guide grooves 11 on both sides to push the moving block 8 at one end of the sliding column 13 to slide on the outer wall of the sliding column 5, guiding the movement. The groove 11 is used to guide the movement direction of the sliding column 13. The sliding column 13 is used to connect the moving block 8 and the guide groove 11 to transmit motion. The sliding column 5 is used to limit the movement trajectory of the moving block 8. The sliding column 5 is used to limit the movement range of the moving block 8. The distance between the two rollers 23 on both sides is adjusted by the moving block 8 so that it matches the outer diameter of the paper cup. The moving block 8 is used to support and adjust the position of the rollers 23 on both sides, thereby achieving the purpose of adjusting the distance between the two rollers 23 on both sides. This solves the problem that the position of the rollers 23 on both sides is relatively fixed in traditional equipment, making it difficult to make targeted adjustments for different paper cup diameters, thus enhancing the practicality of the equipment.

[0019] Reference Figure 1 , Figure 4 and Figure 5The height adjustment assembly includes a limiting post 15, located at the top of the moving block 8. The bottom of the threaded rod 10 is rotatably connected to the inside of the protective shell 22. The limiting post 15 restricts the movement range of the sleeve 2. The sleeve 2 is slidably connected to the outer wall of the limiting post 15, supporting and connecting the roller 4. A rotating post 24 is slidably connected to the inner wall of the limiting post 15, transmitting the force of the push block 18 to achieve height adjustment. Limiting posts 20 are fixedly connected to both ends of the rotating post 24, restricting its movement range. Push blocks 18 are fixedly connected to one side of multiple limiting posts 20, allowing manual operation for height adjustment. A rotating post 17 is rotatably connected inside the push block 18, connecting the fixed block 3 and the push block 18. Fixed blocks 3 are fixedly connected to both ends of the rotating post 17, fixing the position of the sleeve 2. The outer walls of the two fixed blocks 3 are fixed... A spring 16 is fixedly connected to the side wall of the sleeve 2. The spring 16 provides the restoring force to the push block 18. One end of the spring 16 is fixedly connected to the outer wall of the push block 18, and the other end is fixedly connected to the outer wall of the sleeve 2. A cylinder 1 is rotatably connected to the inner wall of the sleeve 2. The cylinder 1 connects the roller 23 and the roller 4. A cylinder 7 is rotatably connected inside each roller 23 to support its rotation. The bottom ends of each column 2 7 are rotatably connected to the inside of the moving block 8. Each column 2 7 has a column 1 fixedly connected to its top. The bottom of the sleeve 2 has a roller 4 fixedly connected to it. The roller 4 is used to support and guide the moving parts. The outer wall of the column 1 is rotatably connected to the inner wall of the roller 2 23, the roller 4 and the sleeve 2 from bottom to top. The inner wall of the column 1 has multiple grooves 14. The grooves 14 are used to engage with the limiting column 15 to fix the height position. The grooves 14 engage with the limiting column 15.

[0020] Specifically, during the adjustment of the positioning height in paper cup production, the push block 18 rotates around the rotating column 17 as its axis. The rotating column 17 serves as the fulcrum for the rotation of the push block 18, and compresses the spring 16 to exert its elasticity. The spring 16 provides a restoring force to return the push block 18 to its original position. As the push block 18 moves, it pushes the limiting column 15 to slide inside the sleeve 2 through the rotating column 24 between the limiting columns 20 on both sides. The limiting column 20 limits the range of movement of the push block 18, and the rotating column 24 transmits the movement of the push block 18 to the limiting column 15 until it separates from the inner wall of the groove 14. The groove 14 engages with the limiting column 15 to fix the height position. The movement direction of the limiting post 15 is limited by the sliding of the inner wall of the sleeve 2. The sleeve 2 is used to support and connect the roller 4 and the roller 23. Next, the sleeve 2 and the roller 4 slide on the cylinder 1. The cylinder 1 is used to support the roller 23 and transmit the rotational motion. When it moves to the specified height, the pressing force on the push block 18 is released. The rebound force of the spring 16 pushes the limiting post 15 to engage with the inner wall of the groove 14 again, thereby adjusting the height of the roller and fixing paper cups of different heights. This achieves the purpose of adjusting the height of the roller 4 according to the height of different paper cups, solving the problem that the positioning height of the traditional device is relatively fixed and it is difficult to make targeted adjustments according to the different heights of paper cups, thus enhancing the applicability of the equipment.

[0021] Working principle: During the paper cup production positioning process, the operator drives the threaded rod 10 to rotate by rotating the knob 9. The rotation of the threaded rod 10 causes the nut 12 to move up and down along the axis of the threaded rod 10. At the same time, the movement of the nut 12 drives the slide plate 19 to move. The movement of the slide plate 19 drives the symmetrically distributed inclined guide grooves 11 on both sides to push the moving block 8 at one end of the sliding column 13 to slide on the outer wall of the sliding column 5. The sliding column 5 limits the movement trajectory of the moving block 8. The moving block 8 is used to adjust the distance between the two rollers 23 on both sides to match the diameter of the outer wall of the paper cup. This achieves the purpose of adjusting the distance between the two rollers 23 on both sides, solving the problem that the position of the rollers 23 in traditional equipment is relatively fixed and it is difficult to make targeted adjustments for different paper cup diameters, thus enhancing the practicality of the equipment.

[0022] During the adjustment of the positioning height in paper cup production, the push block 18 is rotated around the rotating column 17 as the axis, and the spring 16 is compressed to exert its elasticity. As the push block 18 moves, it pushes the limiting column 15 to slide inside the sleeve 2 through the rotating column 24 between the limiting columns 20 on both sides until it separates from the inner wall of the groove 14. The movement direction of the limiting column 15 is limited by the sliding of the inner wall of the sleeve 2. Next, the sleeve 2 and the roller 4 are pushed to slide on the cylinder 1. When it moves to the specified height, the pressing force on the push block 18 is released, and the rebound force of the spring 16 pushes the limiting column 15 to engage with the inner wall of the groove 14 again. This adjusts the height of the roller 4, thereby fixing paper cups of different heights. It achieves the purpose of adjusting the height of the roller 4 according to the height of different paper cups, solving the problem that the positioning height of traditional devices is relatively fixed and it is difficult to make targeted adjustments according to different height paper cups, thus enhancing the applicability of the equipment.
