Technical Field
[0001] This utility model relates to the field of packaging machinery technology, specifically a roll film sealing and cutting machine. Background Technology
[0002] As is well known, in the current packaging machinery field, roll film sealing and cutting machines are one of the key equipment for realizing continuous and automated packaging. They are widely used in the outer packaging of various products. Their core function is to heat-seal and cut the film to completely wrap the product and separate it into independent units, thereby achieving the effects of aesthetics, sealing and moisture prevention.
[0003] However, existing roll-to-roll sealing and cutting equipment still has many shortcomings in practical applications. First, traditional sealing and cutting devices usually separate the cutting and heat sealing processes, which is not only cumbersome and inefficient, but also prone to unstable sealing quality due to uncoordinated actions, affecting the appearance and sealing performance of the finished product.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a roll-to-roll film sealing and cutting machine, comprising a support frame, an upper connecting plate, a lower connecting plate, a sealing and cutting blade, a bidirectional adjustment device, and a driving device. A groove is provided below the support frame, and rectangular slots are formed on the inner walls of both ends of the groove. The upper connecting plate and the lower connecting plate are mounted on both sets of rectangular slots via the bidirectional adjustment device. The sealing and cutting blade is mounted on the bottom wall of the upper connecting plate, and a connecting groove is formed on the top wall of the lower connecting plate. The connecting groove and the sealing and cutting blade are adapted to each other. Electric heating elements are embedded inside both ends of the sealing and cutting blade.

The upper slider and the lower slider are respectively threaded onto the upper and lower ends of the bidirectional screw. The two sets of upper sliders are fixedly connected to the left and right ends of the upper connecting plate, and the two sets of lower sliders are fixedly connected to the left and right ends of the lower connecting plate.
[0009] Furthermore, the present invention is improved in that the driving device includes a cavity, a driven bevel gear, a driving bevel gear, and a drive motor. The cavity is provided in the upper part of the support frame. The driven bevel gear is installed in the cavity through the top ends of the two sets of bidirectional screws.

[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a roll-to-roll film sealing and cutting machine, which has the following beneficial effects:
[0017] This roll-to-roll film sealing and cutting machine, through its upper and lower connecting plates, sealing and cutting blade, connecting groove, and electric heating element, ensures the accuracy and consistency of each sealing and cutting action by precisely matching the sealing and cutting blade with the connecting groove on the lower connecting plate. This effectively reduces the defect rate and improves product quality. The electric heating element is embedded inside the sealing and cutting blade, enabling rapid and uniform heating, allowing the film to be heat-sealed with high quality while being cut. The entire sealing and cutting process integrates both cutting and heat-sealing functions, reducing process steps and greatly improving packaging efficiency while ensuring quality.
[0018] This roll-to-roll film sealing and cutting machine, through its bidirectional adjustment and drive devices, uses a drive motor to drive the active bevel gears on both sides, which in turn drive two sets of driven bevel gears and corresponding bidirectional screws to rotate. This ensures that the bidirectional adjustment devices on both sides operate synchronously. The bidirectional screws use upper and lower sliders that are symmetrically installed. When they rotate, they move at the same speed but in opposite directions, making the process of the upper and lower mating plates approaching or separating more uniform and symmetrical. This ensures that the upper and lower mating plates remain highly stable as they approach or move away, improving the stability of the sealing and cutting action. As a result, it achieves high-precision docking, ensures the consistency of each sealing and cutting action, and improves the yield rate. Attached Figure Description

[0024] 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.
[0025] Please see Figure 1-4A roll-to-roll laminating and sealing machine includes a support frame 1, an upper connecting plate 2, a lower connecting plate 3, a sealing and cutting blade 4, a bidirectional adjustment device, and a drive device. A groove 5 is provided below the support frame 1, and rectangular slots 6 are formed on the inner walls of both ends of the groove 5. The upper connecting plate 2 and the lower connecting plate 3 are mounted on both sets of rectangular slots 6 via the bidirectional adjustment device. The sealing and cutting blade 4 is mounted on the bottom wall of the upper connecting plate 2, and a connecting groove 7 is formed on the top wall of the lower connecting plate 3. The connecting groove 7 is adapted to the sealing and cutting blade 4. Electric heating elements 8 are embedded in the left and right ends of the sealing and cutting blade 4. The drive device, which drives the two sets of bidirectional adjustment devices, is installed above the support frame 1. In this embodiment, during use, the device is installed between the laminating equipment and the heat shrinking equipment. The product to be laminated is placed on the conveyor below the laminating equipment to ensure smooth entry into the machine. The laminating machine then laminates the product. The sealing and cutting blade 4 is connected to an external power source, and the drive device is connected to the control system. The control system then starts the drive device, which will... The bidirectional adjustment device controls the relative position of the upper mating plate 2 and the lower mating plate 3. When the product is conveyed to the sealing and cutting area, that is, when the position to be sealed and cut is about to move below the upper sealing and cutting blade 4, the electric heating element 8 inside the sealing and cutting blade 4 starts to heat up. When the temperature reaches the preset temperature, the bidirectional adjustment device pulls the upper and lower mating plates closer, causing the sealing and cutting blade 4 to enter the mating groove 7 of the lower mating plate 3. The sealing and cutting blade 4 presses down on the mating groove 7 of the lower mating plate 3, cutting the film. Under the action of the electric heating element 8, the film is heat-sealed, thus achieving film sealing. After cutting and heat sealing, the bidirectional adjustment device activates again, pulling apart the upper and lower connecting plates to prepare for the next product. The bidirectional adjustment device allows for easy adjustment of the distance between the upper and lower connecting plates, achieving optimal cutting and sealing effects for the film. The design of the electric heating element 8 embedded in the sealing and cutting blade 4 ensures rapid and uniform heating, improving sealing and cutting efficiency and quality, and reducing sealing defects caused by uneven temperature. The precise fit between the sealing and cutting blade 4 and the connecting groove 7 ensures the accuracy of each sealing and cutting, reducing the defect rate.
[0026] Preferably, in this embodiment, the bidirectional adjustment device includes a bidirectional screw 9, an upper slider 10, and a lower slider 11. The bidirectional screw 9 is rotatably installed in both sets of rectangular slots 6. The upper slider 10 and the lower slider 11 are threaded onto the upper and lower ends of the bidirectional screw 9, respectively. The two sets of upper sliders 10 are fixedly connected to the left and right ends of the upper connecting plate 2, and the two sets of lower sliders 11 are fixedly connected to the left and right ends of the lower connecting plate 3. When the drive device is started, it can synchronously drive the two bidirectional screws 9 to rotate. Since the two ends of the bidirectional screw 9 are respectively connected to the upper slider 10 and the lower slider 11... The sliders 11 move in opposite directions but at the same speed on the screw. When the bidirectional screw 9 rotates clockwise, the upper slider 10 moves downward and the lower slider 11 moves upward, causing the upper docking plate 2 and the lower docking plate 3 to gradually approach each other until they make contact and complete the docking. When the screw rotates counterclockwise, they move in the opposite direction to separate the two docking plates. This symmetrical bidirectional movement ensures that the upper and lower docking plates can approach each other smoothly and ultimately achieve precise docking. The design of the bidirectional screw 9, combined with a synchronous drive mechanism, allows the upper docking plate 2 and the lower docking plate 3 to approach or move away in a uniform and symmetrical manner, significantly improving the accuracy and stability of the docking process.
[0027] Preferably, in this embodiment, the driving device includes a cavity 12, a driven bevel gear 13, a driving bevel gear 14, and a drive motor 15. The cavity 12 is provided above the support frame 1. The driven bevel gear 13 is installed inside the cavity 12 through the top ends of the two sets of bidirectional screws 9. The drive motor 15 is installed in the middle of the cavity 12. The driving bevel gear 14 is installed at both ends of the drive motor 15. The driving bevel gear 14 and the driven bevel gear 13 are meshed and connected. First, when the drive motor 15 is activated, it will start to rotate and drive the driving bevel gear 14 installed at its left and right ends. Since the driving bevel gear 14 and the driven bevel gear 13 are meshed, the rotation of the driving bevel gear 14 will cause the driven bevel gear 13 to rotate accordingly. The driven bevel gear 13 drives the coaxially connected bidirectional screw 9 to rotate. Because there are two sets of bidirectional screws 9, and they are both connected to the driving bevel gear 14 of the drive motor 15 through their respective driven bevel gears 13, these two sets of bidirectional screws 9 can rotate simultaneously in the same direction or in opposite directions. Using a drive motor 15 and a bevel gear system to synchronously drive the two sets of bidirectional screws 9 ensures that the rotation of the two sets of screws can maintain a high degree of consistency and synchronicity.
[0028] Preferably, in this embodiment, the top wall of the support frame 1 is provided with a heat dissipation groove 16 that runs through the cavity 12. The drive motor 15 and transmission components such as bevel gears will generate heat during operation. By setting the heat dissipation groove 16, air circulation can be increased, which can help these key components dissipate heat more quickly and avoid performance degradation or damage due to overheating.
[0029] Preferably, in this embodiment, the drive motor 15 is a servo motor. The servo motor is equipped with an encoder feedback system, which can achieve very precise position control and speed control, ensuring the consistency and accuracy of each operation and improving the quality standards of the product.
[0030] Preferably, in this embodiment, the support frame 1 has a U-shaped design. The U-shaped design provides a stronger frame structure, increases the overall rigidity and stability of the equipment, helps reduce vibration and shaking during operation, and ensures that the machine works smoothly. The U-shaped structure has good anti-torsion performance and can withstand forces from different directions. For components that need to be adjusted or replaced regularly, such as bidirectional adjustment devices and drive motor 15, the U-shaped design provides more convenient operating space and reduces the difficulty of adjustment.
[0031] Preferably, in this embodiment, mounting plates 17 are installed on the bottom walls of both ends of the support frame 1. Mounting holes 18 are provided on the mounting plates 17. The entire equipment can be firmly fixed to the ground or workbench through the mounting holes 18 on the mounting plates 17 to prevent displacement caused by vibration during machine operation, and to ensure stability and safety during operation. The preset mounting holes 18 make the equipment installation more standardized and modular, which facilitates rapid deployment and reduces the need for on-site customization.
[0032] Preferably, in this embodiment, a camera 19 is installed on one side wall of the support frame 1. The sealing and cutting process is monitored in real time by the camera 19. The operator can immediately detect any abnormalities, such as incomplete sealing and cutting, positional deviation, or material jamming, and take corrective measures quickly. The camera 19 system can automatically detect potential problems, such as wear of the cutting tool or poor sealing, and issue an alarm in time to prevent small problems from developing into major failures.
