Description
Technical Field
[0001] This utility model relates to the field of edge pressing device technology, specifically to an edge pressing device for producing paper-pulled heat-sealed paper film. Background Technology
[0002] Paper-tissue heat-sealable film is a composite material specifically used for packaging daily necessities such as tissues and wet wipes. In the production process of paper-tissue heat-sealable film, an edge pressing process is often required, which is a key process to ensure the sealing performance of the film edges, structural stability, and reliability of subsequent use. In existing technologies, mechanical pressing and heat are generally used to achieve tight adhesion of the paper film edges (usually multi-layered sections) to form a strong and sealed edge. The paper film is unwound by an unwinding mechanism and kept stable by guide rollers and a tension control system to ensure edge alignment. The multiple paper films overlap and are in the heat-sealing position. The heat-sealing knife is heated and moved downwards, contacting and stopping the paper film, causing the heat-sealing layers on the multiple paper film surfaces to melt and penetrate each other, ensuring tight adhesion. However, although the multiple paper films are pressed and overlapped by pressure rollers, gaps may exist between the multiple paper films after they move to the heat-sealing position, resulting in insufficient adhesion strength and poor heat-sealing effect. Utility Model Content
[0003] To overcome the above-mentioned defects, the present invention provides a pressing device for producing paper-pulled heat-sealed paper film, which solves the technical problem in the prior art that gaps may exist between multiple paper films, resulting in insufficient bonding strength of multiple paper films and poor heat-sealing effect.
[0004] According to one aspect, at least one embodiment of the present invention provides a pressing device for producing heat-sealed paper film, including a base, a support frame, a movable seat, a mounting seat, a mounting frame, a rubber roller, a pressing component, and a heat-sealing mechanism. The support frame is fixedly connected to the base. The movable seat is longitudinally movable within the support frame via a first electric cylinder. The mounting seat is elastically connected to the movable seat via an elastic connector. The mounting frame is movably disposed at one end of the mounting seat via a moving mechanism. The rubber roller is rotatably disposed within the mounting frame via a rotating mechanism for pressing the paper film and cleaning dust from the surface of the paper film. The pressing component is disposed within the mounting seat for pressing the paper film. The heat-sealing mechanism is disposed on the mounting seat for heat-sealing the paper film.

[0006] Furthermore, the moving mechanism includes a threaded rod, a sliding sleeve, and a first motor. A moving groove is provided in the mounting base, and the threaded rod is rotatably disposed in the moving groove. One end of the sliding sleeve is threadedly engaged with the threaded rod, and the other end is fixedly connected to the mounting bracket. The first motor is mounted on the mounting base, and the output end of the first motor is coaxially fixedly connected to one end of the threaded rod.
[0007] Furthermore, the rotating mechanism includes a support shaft, a first gear, a second gear, a third gear, and a second motor. The support shaft is rotatably mounted within the mounting frame. The rubber roller is fitted onto the support shaft and is coaxially and fixedly connected to it. The first gear is fitted onto the support shaft and is coaxially and fixedly connected to it. The second gear is rotatably mounted within the support frame via a first rotating shaft and meshes with the first gear. A protruding seat is fixedly mounted on the support frame. The third gear is rotatably mounted within the protruding seat via a second rotating shaft. The second motor is mounted on the support frame, and its output end is coaxially and fixedly connected to the second rotating shaft.
[0008] As a further embodiment of this application, the clamping assembly includes a connecting frame and an abutment plate, one end of the connecting frame being fixedly connected to the outer side wall of the movable seat, and one end of the abutment plate being fixedly connected to the other end of the connecting frame.
[0009] As a further embodiment of this application, the heat sealing mechanism includes a mounting plate, a second electric cylinder, and a heat sealing blade. One end of the mounting plate is fixedly connected to the outer wall of the mounting base. The second electric cylinder is mounted on the mounting plate, and its output end extends through the mounting plate. One end of the heat sealing blade is fixedly connected to the output end of the second electric cylinder.
[0010] Based on the aforementioned scheme, the connecting frame is L-shaped, and a rubber pad is fixedly installed at the other end of the abutment plate.
[0011] Furthermore, based on the aforementioned scheme, the heat sealing knife is positioned between the abutment plate and the rubber roller and is perpendicular to the base.

[0022] like Figures 1-4As shown, it illustrates a pressing device for producing heat-sealed paper film using a paper puller according to an embodiment of the present invention, including a base 1, a support frame 2, a movable seat 3, a mounting seat 4, a mounting frame 5, a rubber roller 6, a pressing component, and a heat sealing mechanism; The support frame 2 is fixedly connected to the base 1. The support frame 2 is a U-shaped frame. The movable seat 3 is longitudinally movable inside the support frame 2 via the first electric cylinder 28. The first electric cylinder 28 is installed on the support frame 2. The output end of the first electric cylinder 28 passes through the support frame 2 and is fixedly connected to one end of the movable seat 3. Mounting base 4 is elastically connected to movable base 3 via an elastic connector. The elastic connector includes movable plate 7, spring 9 and connecting rod 10. Movable base 3 has a cavity 8. Movable plate 7 is slidably disposed in cavity 8. The outer side wall of movable plate 7 abuts against and slides against the inner wall of cavity 8. The two ends of spring 9 are fixedly connected to the inner top wall of cavity 8 and one end of movable plate 7, respectively. One end of connecting rod 10 is fixedly connected to mounting base 4, and the other end passes through movable base 3 and is fixedly connected to the other end of movable plate 7. like Figure 2 As shown, the mounting bracket 5 is movably mounted at one end of the mounting base 4 via a moving mechanism. The moving mechanism includes a threaded rod 11, a sliding sleeve 12, and a first motor 13. A moving groove is provided inside the mounting base 4. The threaded rod 11 is rotatably mounted in the moving groove and is parallel to the base 1. A telescopic protective sleeve is fitted on the outside of the threaded rod 11. One end of the sliding sleeve 12 is threadedly engaged with the threaded rod 11, and the other end is fixedly connected to the mounting bracket 5. The first motor 13 is mounted on the mounting base 4. The output end of the first motor 13 is coaxially fixedly connected to one end of the threaded rod 11. By starting the first motor 13, the output end of the first motor 13 rotates, driving the threaded rod 11 to rotate. The threaded rod 11 drives the sliding sleeve 12 to move along the inner wall of the moving groove, and the sliding sleeve 12 drives the mounting bracket 5 to move horizontally above the base 1. like Figure 2 and Figure 3As shown, the rubber roller 6 is rotatably mounted inside the mounting frame 5 via a rotating mechanism. It is used to compact the paper film and clean dust from its surface. The rotating mechanism includes a support shaft 14, a first gear 15, a second gear 16, a third gear 18, and a second motor 21. The support shaft 14 is rotatably mounted inside the mounting frame 5. The rubber roller 6 is fitted onto the support shaft 14 and coaxially fixedly connected to it. The rubber roller 6 is detachably mounted on the support shaft 14. The first gear 15 is fitted onto the support shaft 14 and coaxially fixedly connected to it. The second gear 16 is rotatably mounted inside the support frame 2 via a first rotating shaft 17. The second gear 16 meshes with the first gear 15. A protruding seat 19 is fixedly mounted on the support frame 2. The protruding seat 19 is connected to the mounting frame... 5 is an "integrated" structure. The protruding seat 19 and the mounting bracket 5 have a rotating cavity. The third gear 18 is rotatably mounted in the protruding seat 19 via the second rotating shaft 20. The first gear 15, the second gear 16, and the third gear 18 are all rotatably mounted in the rotating cavity. The second motor 21 is mounted on the support frame 2. The output end of the second motor 21 is coaxially and fixedly connected to the second rotating shaft 20. By starting the second motor 21, the output end of the second motor 21 rotates, driving the second rotating shaft 20 to rotate. The rotation of the second rotating shaft 20 drives the third gear 18 to rotate. The third gear 18 drives the second gear 16 to rotate. The second gear 16 drives the first gear 15 to rotate. The first gear 15 drives the support shaft 14 to rotate. The support shaft 14 drives the rubber roller 6 to rotate. like Figure 1 and Figure 4 As shown, the clamping assembly is installed inside the mounting base 4 to clamp the paper film. The clamping assembly includes a connecting frame 22 and an abutment plate 23. One end of the connecting frame 22 is fixedly connected to the outer wall of the movable base 3, and one end of the abutment plate 23 is fixedly connected to the other end of the connecting frame 22. The connecting frame 22 is L-shaped. A rubber pad 27 is fixedly installed on the other end of the abutment plate 23 to increase the friction with the paper film. The bottom end of the rubber pad 27 is on the same horizontal line as the bottom end of the rubber roller 6. When the first electric cylinder 28 is activated, the first electric cylinder 28 drives the movable base 3 to move downward. The movable base 3 drives the mounting base 4, the mounting frame 5, the rubber roller 6, the connecting frame 22, and the abutment plate. 23 moves downwards, and the rubber roller 6 and rubber pad 27 simultaneously abut against the paper film placed on the base 1. In the subsequent push of the first electric cylinder 28, the rubber roller 6 and rubber pad 27 undergo elastic deformation and generate an upward reaction force, which drives the moving plate 7 to move upwards and squeeze the spring 9. The spring 9 contracts and deforms. At this time, the first electric cylinder 28 is closed, thus elastically pressing the paper film. By starting the second motor 21 and the first motor 13, the rubber roller 6 is driven to rotate and move away from the abutment plate 23, thus cleaning the dust on the paper film and, together with the abutment plate 23 and rubber pad 27, flattening multiple overlapping paper films and eliminating air bubbles. It should be added that the width of the paper film is smaller than the width of the rubber roller 6. The rubber roller 6 moves horizontally when rotating. Since the heat-sealing area of the paper film is a straight line, the rubber roller 6 only needs to remove the dust near the heat-sealing area. Therefore, the rubber roller 6 does not rotate 180 degrees during the process of removing the dust near the heat-sealing area, which makes it less likely that the dust attached to the rubber roller 6 will scratch the surface of the paper film. like Figure 4 As shown, the heat sealing mechanism is mounted on the mounting base 4 and is used to heat seal the paper film. The heat sealing mechanism includes a mounting plate 24, a second electric cylinder 25, and a heat sealing knife 26. One end of the mounting plate 24 is fixedly connected to the outer wall of the mounting base 4. The second electric cylinder 25 is mounted on the mounting plate 24. The output end of the second electric cylinder 25 passes through the mounting plate 24 and extends outward. One end of the heat sealing knife 26 is fixedly connected to the output end of the second electric cylinder 25. The heat sealing knife 26 is located between the abutment plate 23 and the rubber roller 6 and is perpendicular to the base 1. A resistance wire is embedded inside the blade of the heat sealing knife 26. When the resistance wire is energized, the heat sealing knife 26 is heated. By starting the second electric cylinder 25, the heat sealing knife 26 is moved vertically toward the paper film. With the help of contact pressure, the edge of the film is melted and bonded. Working principle: When the edge pressing device for heat-sealing paper film production performs edge pressing and heat sealing, multiple overlapping paper films are placed on the base 1 and below the rubber roller 6 and the abutment plate 23. The area to be heat-sealed is directly below the heat-sealing knife 26. The first electric cylinder 28 is activated to drive the moving seat 3 to move downward. The moving seat 3 drives the mounting seat 4, mounting frame 5, rubber roller 6, connecting frame 22 and abutment plate 23 to move downward. The rubber roller 6 and rubber pad 27 simultaneously abut against the paper film placed on the base 1. In the subsequent push of the first electric cylinder 28, the rubber roller 6 and rubber pad 27 undergo elastic deformation and generate an upward reaction force, which drives the moving plate 7 to move upward and squeeze the spring 9. The spring 9 contracts and deforms. At this time, the first electric cylinder 28 is closed, thus elastically pressing the paper film. By starting the second motor 21 and the first motor 13, the output end of the second motor 21 rotates, driving the second shaft 20 to rotate. The rotation of the second shaft 20 drives the third gear 18 to rotate, the third gear 18 drives the second gear 16 to rotate, the second gear 16 drives the first gear 15 to rotate, the first gear 15 drives the support shaft 14 to rotate, the support shaft 14 drives the rubber roller 6 to rotate, and the output end of the first motor 13 rotates, driving the threaded rod 11 to rotate. The threaded rod 11 drives the sliding sleeve 12 to move along the inner wall of the moving groove. The sliding sleeve 12 drives the mounting bracket 5 to move horizontally above the base 1. This drives the rubber roller 6 to rotate and move away from the abutment plate 23, thus cleaning the dust on the paper film and, together with the abutment plate 23 and the rubber pad 27, flattening multiple overlapping paper films and eliminating air bubbles. Finally, the resistance wire is energized to heat the heat sealing knife 26. The second electric cylinder 25 is activated to drive the heat sealing knife 26 to move vertically toward the paper film, and the contact pressure is used to melt and bond the edge of the film.
