Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, and in particular to a high-efficiency plastic film heat-sealing bag making machine. Background Technology

[0002] In the production process of plastic film products, heat-sealing bag-making machines play a crucial role. In numerous fields such as food packaging and daily necessities packaging, plastic films are needed to be made into bags of various sizes to hold goods. To ensure the airtightness of the packaging and the quality of the product, the heat-sealing process is indispensable. Heat-sealing bag-making machines can efficiently heat-seal plastic films to achieve the purpose of bag making, greatly improving production efficiency and meeting the large market demand for plastic products.

[0003] Existing heat-sealing bag-making machines typically use a heating device to heat a heat-sealing plate, which then presses and heats the plastic film to fuse and seal it. However, during the heat-sealing process, the plastic film easily softens at high temperatures and sticks to the heat-sealing plate, resulting in some plastic residue remaining on the outer wall of the plate. With each heat-sealing cycle, this residual plastic gradually accumulates, not only affecting the normal heat transfer of the heat-sealing plate and reducing the heat-sealing effect, but also causing unevenness and poor sealing at the seal of the heat-sealed plastic bag. This prevents the plastic bags from being properly heat-sealed during production, severely impacting product quality and production efficiency, and increasing production costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency plastic film heat-sealing bag making machine, which aims to improve the problem in the prior art that as the number of heat-sealing times increases, residual plastic will gradually accumulate, affecting the normal heat transfer of the heat-sealing plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency plastic film heat-sealing bag making machine, including a base, a working platform fixedly connected to the upper surface of the base, a frame fixedly connected to the upper surface of the working platform, a first outer shell slidably connected inside the frame, a scraper fixedly connected to the upper surface of the first outer shell, a reset component provided inside the first outer shell, a slider slidably connected inside the first outer shell, a second connecting plate fixedly connected to the upper surface of the slider, and a scraper fixedly connected to the outer wall of the second connecting plate.

[0006] Furthermore, the reset assembly includes a spring, both ends of which are fixedly connected to the outer wall of the slider, and a guide rod is provided inside the spring, both ends of which are fixedly connected to the outer wall of the slider.

[0007] Furthermore, a bracket is fixedly connected to the upper surface of the work platform, a connecting rod two is fixedly connected to the lower surface of the bracket, a mounting plate one is fixedly connected to the lower surface of the connecting rod two, a mounting plate two is slidably connected to the lower surface of the mounting plate two, and a heat-sealing plate is fixedly connected to the lower surface of the mounting plate two.

[0008] Furthermore, a connecting rod is slidably connected inside the mounting plate, and a threaded rod is fixedly connected to the upper end of the connecting rod, with a nut threadedly connected to the outer wall of the threaded rod.

[0009] Furthermore, an elastic plate is fixedly connected to the outer wall of the connecting rod, a threaded sleeve is slidably connected to the outer wall of the elastic plate, a torsion is fixedly connected to the lower surface of the threaded sleeve, the outer wall of the threaded sleeve is threadedly connected to the inside of the mounting plate, and the elastic plate base is fixedly connected to the inside of the mounting plate.

[0025] Specifically, a high-efficiency plastic film heat-sealing bag making machine includes a base 2, which serves as the supporting foundation for the entire equipment. A working platform 4 is fixedly connected to the upper surface of the base 2. The working platform 4 is used to support the plastic film and related operations during the heat-sealing bag making process, providing a flat and stable working area for heat-sealing bag making. A frame 5 is fixedly connected to the upper surface of the working platform 4, providing a track for the sliding of the outer shell 14, ensuring that the outer shell 14 can move along a specific path, thereby ensuring that the scraper 13 can accurately clean the heat-sealing plate 7. The outer shell 14 is slidably connected inside the frame 5. The sliding of the outer shell 14 within the frame 5 can drive the scraper 13 to move, realizing the cleaning of different positions of the heat-sealing plate 7, expanding the cleaning range, and improving cleaning efficiency. The outer casing 14 has a scraper 13 fixedly connected to its upper surface. The scraper 13 is a key component for cleaning the heat-sealing plate 7. During the heat-sealing bag-making process, plastic residue will remain on the outer wall of the heat-sealing plate 7. The scraper 13 can directly contact the heat-sealing plate 7 and scrape off this residual plastic, effectively solving the problem of heat transfer and heat-sealing effect affected by plastic residue. The outer casing 14 has a reset component inside, which includes a spring 9. Both ends of the spring 9 are fixedly connected to the outer wall of the slider 8. The spring 9 has a guide rod 10 inside, both ends of which are fixedly connected to the outer wall of the slider 8. The function of the reset component is to enable the slider 8 to automatically reset after movement. When the button 16 is pressed, the slider 8 slides to expand the width of the scraper 13. When the button 16 is pressed again, the spring 9 will spring back. Under the guidance of the guide rod 10, the force drives the slider 8 back to its initial position for the next use. The slider 8 is slidably connected inside the outer casing 14. The slider 8 can slide within the outer casing 14, and by sliding the slider 8, the width of the scraper 13 can be adjusted to adapt to heat-sealing plates 7 of different sizes, achieving more comprehensive cleaning and improving the applicability of the equipment. A connecting plate 25 is fixedly connected to the upper surface of the slider 8, and the scraper 13 is fixedly connected to the outer wall of the connecting plate 25. The connecting plate 25 connects the slider 8 and the scraper 13, allowing the movement of the slider 8 to be transmitted to the scraper 13, ensuring that the scraper 13 moves accurately under the drive of the slider 8, thus achieving the cleaning function of the heat-sealing plate 7. An outer casing 17 is fixedly connected to the upper surface of the outer casing 14. Shell 2 17 provides an installation position for connecting plate 15, ensuring that these components are not disturbed by external factors and operate stably during equipment operation. Connecting plate 15 is fixedly connected to the outer wall of shell 2 17, and both sides of connecting plate 15 are fixedly connected to the outer wall of scraper 13. Connecting plate 15 connects shell 2 17 and scraper 13, further enhancing the stability of scraper 13. Button 16 is slidably connected inside shell 2 17. A locking block 12 is fixedly connected to the sliding end of button 16. When button 16 is pressed, locking block 12 slides together with button 16. Locking block 12 cooperates with slider 8 and elastic block 11. The operation of button 16 can control the sliding of slider 8, thereby adjusting the width of scraper 13, facilitating the cleaning of heat-sealing plates 7 of different sizes.The outer wall of the locking block 12 is slidably connected to the outer wall of the slider 8. An elastic block 11 is fixedly connected inside the outer casing 14. The outer wall of the locking block 12 is slidably connected to the outer wall of the elastic block 11. When button 16 is pressed, the locking block 12 slides and pushes the slider 8 to slide, ensuring that the locking block 12 can stably remain in the corresponding position when button 16 is not operated. This ensures that the slider 8 will not slide arbitrarily when not subjected to external force, maintaining the initial state of the scraper 13. A guide plate 3 is fixedly connected inside the base 2. The guide plate 3 is used to guide the scraped plastic out of the working area, preventing the scraped plastic from accumulating inside the equipment and avoiding affecting the normal operation of the equipment.

[0026] Reference Figure 1 , Figure 2 and Figure 5 The upper surface of the working platform 4 is fixedly connected to a bracket 1. The lower surface of the bracket 1 is fixedly connected to a connecting rod 26. The lower surface of the connecting rod 26 is fixedly connected to a mounting plate 6. The lower surface of the mounting plate 6 is slidably connected to a mounting plate 20. The lower surface of the mounting plate 20 is fixedly connected to a heat-sealing plate 7. The interior of the mounting plate 6 is slidably connected to a connecting rod 21. The upper end of the connecting rod 21 is fixedly connected to a threaded rod 18. The outer wall of the threaded rod 18 is threadedly connected to a nut 19. The outer wall of the connecting rod 21 is fixedly connected to an elastic plate 22. The outer wall of the elastic plate 22 is slidably connected to a threaded sleeve 23. The lower surface of the threaded sleeve 23 is fixedly connected to a torsion 24. The outer wall of the threaded sleeve 23 is threadedly connected to the interior of the mounting plate 20. The base of the elastic plate 22 is fixedly connected to the interior of the mounting plate 20.

[0027] Specifically, a bracket 1 is fixedly connected to the upper surface of the work platform 4, serving as a support and positioning element. A connecting rod 26 is fixedly connected to the lower surface of the bracket 1. The connecting rod 26 can be driven downwards by the internal drive device of the bracket 1 for heat sealing. A mounting plate 6 is fixedly connected to the lower surface of the connecting rod 26, providing mounting positions for components such as the mounting plate 20 and the connecting rod 21. The mounting plate 20 is slidably connected to the lower surface of the mounting plate 6, allowing it to slide on the mounting plate 6. It can be easily replaced. A heat-sealing plate 7 is fixedly connected to the lower surface of mounting plate 20. The heat-sealing plate 7 is the core component for heat-sealing plastic film into bags. During operation of the heat-sealing bag-making machine, the heat-sealing plate 7 is heated to a suitable temperature. By contacting the plastic film and applying a certain pressure, the plastic film softens and fuses together, thus completing the heat-sealing operation. A connecting rod 21 is slidably connected inside mounting plate 16. The sliding connection between the connecting rod 21 and mounting plate 16, along with the threaded rod 18 and nut 19, further enhances the fixation effect on the position of the heat-sealing plate 7, making it more stable. A threaded rod 18 is fixedly connected to the upper end of connecting rod 21. A nut 19 is threadedly connected to the outer wall of threaded rod 18. The threaded rod 18 and nut 19 work together to strengthen the fixation of heat sealing plate 7. When nut 19 is rotated, it will compress connecting rod 21, enhancing the fixation effect. An elastic plate 22 is fixedly connected to the outer wall of connecting rod 21. The elastic plate 22 plays a role in buffering and compensation. During the heat sealing process, mounting plate 20 can be stably installed on the lower surface of mounting plate 6. A threaded sleeve 23 is slidably connected to the outer wall of elastic plate 22. A torsion sleeve 23 is fixedly connected to the lower surface of the threaded sleeve 23. Rotating 24 allows the threaded sleeve 23 to be pressed inward, thus pressing the elastic plate 22 inward and clamping it to enhance the fixing effect. The outer wall of the threaded sleeve 23 is threadedly connected to the inside of the mounting plate 20, allowing the threaded sleeve 23 to move inward to facilitate fixing. The base of the elastic plate 22 is fixedly connected to the inside of the mounting plate 20. This connection method securely mounts the elastic plate 22 on the mounting plate 20. When the threaded sleeve 23 presses against the elastic plate 22, it facilitates the fixing of the heat-sealing plate 7.

[0028] Working principle: Before the heat sealing operation, adjust the position and angle of the heat sealing plate 7 according to the thickness and material of the plastic film. Rotate the nut 19, and the threaded rod 18 drives the connecting rod 21 to slide up and down within the mounting plate 6, thereby adjusting the height of the mounting plate 20 and the heat sealing plate 7 to ensure that the heat sealing plate 7 can fit tightly with the plastic film. If a fine adjustment of the angle of the heat sealing plate 7 is required, rotate the torsion 24 to rotate the threaded sleeve 23. Since the threaded sleeve 23 is threadedly connected to the mounting plate 20, the mounting plate 20 will rotate, thereby adjusting the angle of the heat sealing plate 7 to ensure uniform heat sealing. When the equipment is started, the heat sealing plate 7 is heated to the set temperature. The drive device inside the bracket 1 drives the connecting rod 26 to move downward. The mounting plate 6, mounting plate 20, and heat sealing plate 7 then descend. The heat sealing plate 7 contacts and presses the plastic film, using high temperature to soften and fuse the plastic film, completing the heat sealing operation and making a bag. During equipment standby or heat sealing operation intervals, the scraper 13 is in the initial position. At this time, the sliding... Block 8 remains in its initial state under the action of the reset component, and the width of scraper 13 is fixed, ready for cleaning. When it is necessary to clean the heat-sealing plate 7, especially the larger heat-sealing plate 7, press button 16. The locking block 12 at the sliding end of button 16 slides accordingly. The locking block 12 pushes the slider 8 to slide inside the outer shell 14. The slider 8 drives the connecting plate 25 and scraper 13 to move, thereby expanding the width of scraper 13 to accommodate the size of heat-sealing plate 7. The outer shell 14 can be slid inside the frame 5 manually or through the equipment program. The scraper 13 moves accordingly and contacts the outer wall of the heat-sealing plate 7 to scrape off the plastic remaining during the heat sealing process. The scraped plastic is moved out of the working area under the guidance of guide plate 3 to prevent accumulation from affecting the operation of the equipment. After cleaning is completed, press button 16 again. The locking block 12 separates from the slider 8. The spring 9 generates elastic force and, under the guidance of guide rod 10, drives slider 8 back to the initial position. The width of scraper 13 returns to its initial state, waiting for the next cleaning operation.
