Description

Technical Field

[0001] The utility model relates to the field of packaging engineering, in particular to a yogurt cup lid film sealing and easy-to-tear film laminating device. Background Art

[0002] The yogurt cup lid film sealing and easy-to-tear film laminating device can make multiple layers of easy-to-tear films form a tighter sealing layer after lamination, effectively preventing the influence of external factors such as oxygen and moisture on the product, thereby prolonging the shelf life and stability of the product. The multi-layer structure can provide better physical protection, such as shock resistance and tear resistance, reducing the damage to the product during transportation and storage. By adjusting the materials and properties of each layer of film, different packaging requirements of products can be met, such as moisture-proof, oil-proof, light-blocking, freshness-keeping, etc.

[0003] The main function of the existing yogurt cup lid film sealing and easy-to-tear film laminating device is to accurately and firmly laminate multiple layers of easy-to-tear films together to form a composite material with specific properties (such as easy tearability, sealing performance, strength, etc.). Its purpose is to meet the needs of packaging, protection, identification or other specific uses. Each film supply unit is responsible for conveying a roll of easy-to-tear film to a designated position, and cutting the film material into sheets of appropriate length or maintaining continuous supply through a cutting mechanism. The conveyor belt is used to precisely stack the layers of easy-to-tear films together, and the easy-to-tear films are bonded together by spraying glue. An alignment device is used in this process to ensure the accurate alignment between the layers of film, and finally the laminated easy-to-tear film is collected.

[0004] The existing yogurt cup lid film sealing and easy-to-tear film laminating device makes the easy-to-tear films accurately laminate together through a conveyor belt and an alignment device. However, due to the fixed width of the conveyor belt, the width of the easy-to-tear film that can be processed is also limited. For certain products with specific sizes, if a laminating device with a fixed width is used, it may cause deviation on the production line because the size of the product is smaller than the size that the device can fix, increasing the probability of waste and reducing the production efficiency. Therefore, a yogurt cup lid film sealing and easy-to-tear film laminating device is proposed to solve the above problems. Summary of the Utility Model

[0033] Refer to Figure 1 、 Figure 4 、 Figure 6, an embodiment provided by the present utility model: a yogurt cup lid film sealing and easy-to-tear film fitting device, including a bottom plate 1, the bottom plate 1 provides a stable support effect for the overall device, enabling the device to operate stably. A fixing mechanism is provided on the top of the bottom plate 1. The fixing mechanism includes a guide rod 21, which provides a stable up-and-down guiding effect for the fixing mechanism. The outer wall of the guide rod 21 is slidably connected to an L-shaped rod 20, enabling the guide rod 21 to provide a stable sliding effect for the L-shaped rod 20, so that the L-shaped rod 20 can slide up and down along the outer wall of the guide rod 21, and the guide rod 21 provides a guiding function for the L-shaped rod 20. The inner wall of the L-shaped rod 20 is slidably connected to a grip 12, enabling the grip 12 to slide stably along the inner wall of the L-shaped rod 20. A baffle 27 is fixedly connected to the left side of the grip 12, so that the baffle 27 can be moved by pulling the grip 12. The outer wall of the baffle 27 is elastically connected to the inner wall of the L-shaped rod 20 through a spring 26. One end of the spring 26 is fixedly connected to the outer wall of the baffle 27, and the other end of the spring 26 is fixedly connected to the inner wall of the L-shaped rod 20, so that the spring 26 provides a reaction force for the baffle 27 through the inner wall of the L-shaped rod 20. A cylinder 25 is fixedly connected to the left side of the baffle 27, so that when the grip 12 is pulled, the baffle 27 can drive the cylinder 25 to release the fixation with the circular groove, enabling the grip 12 to drive the L-shaped rod 20 to vertically adjust its position. The cylinder 25 is slidably connected to the inner wall of the L-shaped rod 20, enabling the L-shaped rod 20 to provide a stable sliding effect for the cylinder 25, so that the cylinder 25 can slide stably along the inner wall of the L-shaped rod 20. A positioning rod 13 is slidably connected to the inner wall of the L-shaped rod 20, enabling the positioning rod 13 to provide a stable sliding effect for the L-shaped rod 20, so that the positioning rod 13 slides stably along the outer wall of the L-shaped rod 20. A circular groove is provided on the right side of the positioning rod 13, and multiple groups of circular grooves are vertically arranged, so that the cylinder 25 is inserted into circular grooves at different positions, enabling the device to reach different states. The outer wall of the cylinder 25 is inserted into the inner wall of the circular groove, and the insertion of the cylinder 25 into the circular groove makes the device reach a fixed state, enabling the device to operate stably. Both ends of the positioning rod 13 are fixedly connected to a support frame 24, enabling the support frame 24 to provide a stable fixing effect for the positioning rod 13. The bottom of the support frame 24 is fixedly connected to the top of the bottom plate 1, enabling the bottom plate 1 to provide a stable fixing effect for the support frame 24. The inner wall of the support frame 24 is rotatably connected to a lower pressing rod 19, enabling the support frame 24 to provide a stable rotating effect for the lower pressing rod 19, so that the lower pressing rod 19 and the upper pressing rod 7 cooperate to press the easy-to-tear film flat and tightly together. A sliding block 6 is rotatably connected to the outer wall of the lower pressing rod 19. The sliding blocks 6 are arranged in two pairs on the left and right, enabling the sliding blocks 6 to move along the lower pressing rod 19 to limit easy-to-tear films of different sizes.

[0034] Refer to Figure 2 , Figure 3 , Figure 5, the bottom of the sliding block 6 is hinged with a connecting piece 22 through a connecting rod 23. One end of the connecting rod 23 is hinged to the bottom of the sliding block 6, and the other end of the connecting rod 23 is hinged to the inner wall of the connecting piece 22. The bottom of the connecting piece 22 is fixedly connected to the top of the L-shaped rod 20. When the staff steps on the grip 12 and moves downward, the L-shaped rod 20 moves downward along the guide rod 21, so that the connecting piece 22 fixedly connected to the L-shaped rod 20 drives the connecting rod 23 to move downward, and the sliding block 6 hinged to the connecting rod 23 moves closer to the middle. The inner wall of the support frame 24 is rotatably connected with an upper pressing rod 7, so that the support frame 24 provides a stable rotation effect for the upper pressing rod 7. The outer wall of the upper pressing rod 7 is rotatably connected with the inner wall of the sliding block 6, so that the sliding block 6 can slide stably along the outer wall of the upper pressing rod 7, and the sliding block 6 limits the tear film of different sizes. The rear end of the outer wall of the support frame 24 is fixedly connected with a connecting plate 15, so that the support frame 24 provides a stable support effect for the connecting plate 15. The inner wall of the connecting plate 15 is fixedly connected with a scraping plate 18, so that the connecting plate 15 provides a stable fixing effect for the scraping plate 18, and the scraping plate 18 can scrape the sprayed glue flat on the surface of the tear film. The outer wall of the scraping plate 18 is slidably connected with a connecting block 17. The front end of the outer wall of the connecting block 17 is fixedly connected with the sliding block 6, so that when the staff adjusts the limit, it will not affect the working state of the scraping plate 18. The rear end of the outer wall of the connecting block 17 is fixedly connected with a sleeve 16. The sleeve 16 is arranged at both ends of the spray pipe 14. The inner wall of the sleeve 16 is slidably connected with the spray pipe 14. The sleeve 16 is fixedly connected with the sliding block 6 through the connecting block 17. When the staff adjusts the limit, the sleeve 16 will close the position where the glue does not need to be sprayed from the spraying hole 28, so that the glue will not be sprayed from the covered position. The outer wall of the spray pipe 14 is provided with spraying holes 28, so that the glue is evenly sprayed out from the spraying holes 28. The bottom of the spray pipe 14 is fixedly connected with a vertical rod 29, so that the vertical rod 29 provides a stable support effect for the spray pipe 14. The vertical rod 29 is fixedly connected with the outer wall of the bottom plate 1, so that the bottom plate 1 provides a stable support effect for the vertical rod 29. The outer wall of the vertical rod 29 is slidably connected with the outer wall of the sleeve 16, so that the sleeve 16 being driven by the sliding block 6 will not affect the operation of the spray pipe 14.

[0035] Refer to Figures 1 - 3, a support rod 10 is fixedly connected to the front end of the outer wall of the bottom plate 1, so that the bottom plate 1 provides a stable support effect for the support rod 10. The inner wall of the support rod 10 is rotatably connected to a winding rod 9, so that the support rod 10 provides a stable rotation effect for the winding rod 9, enabling the winding rod 9 to rotate along the inner wall of the support rod 10 to collect the tearable film that has been adhered together. A support block 11 is fixedly connected to the front end of the outer wall of the bottom plate 1, so that the bottom plate 1 provides a stable support effect for the support block 11. A motor 8 is fixedly connected to the top of the support block 11, so that the support block 11 provides a stable support effect for the motor 8. The output end of the motor 8 is fixedly connected to the winding rod 9, so that the motor 8 provides rotational power for the winding rod 9, enabling the winding rod 9 to collect the tearable film that has been adhered together. A fixing frame 4 is fixedly connected to the rear end of the outer wall of the bottom plate 1, so that the bottom plate 1 provides a stable support effect for the fixing frame 4. The inner wall of the fixing frame 4 is rotatably connected to a transmission rod 5, so that the fixing frame 4 provides a stable rotation effect for the transmission rod 5, enabling the transmission rod 5 to rotate stably along the inner wall of the fixing frame 4, and enabling the transmission rod 5 to convey the film material forward. The inner wall of the fixing frame 4 is rotatably connected to a rolling rod 3, and the inner wall of the fixing frame 4 is rotatably connected to a long rod 2. The rolling rod 3 and the long rod 2 are vertically offset, so that the rolling rod 3 can press the film material forward for transmission and is not easily deflected.

[0036] Working principle: After the film material is cut and enters the laminating device, the upper film material is conveyed forward by the transmission rod 5, and the lower film material is conveyed forward between the rolling rod 3 and the long rod 2 until they are simultaneously conveyed between the upper pressing rod 7 and the lower pressing rod 19. At the same time, the spraying holes 28 on the outer wall of the spray pipe 14 start to spray glue on the bottom of the upper film material. When the upper film material is conveyed forward, the glue on the film material is scraped flat by the scraper 18, so that the upper and lower film materials are tightly laminated together through the extrusion of the upper pressing rod 7 and the lower pressing rod 19. At this time, the winding rod 9 is driven by the output rod of the motor 8 to roll up and collect the laminated tearable film.

[0037] When the device needs to laminate small-sized film materials, the staff pulls the handle 12 backward, so that the cylinder 25 of the baffle 27 and the handle 12 moves backward, disengaging the plugging effect with the circular groove. At this time, the staff vertically moves the handle 12 to move the L-shaped rod 20, so that the connecting rod 23 hinged to the connecting piece 22 drives the two sliding blocks 6 to move horizontally closer. After reaching the required position, the handle 12 is released, and the cylinder 25 is plugged into the circular groove under the reaction force generated by the spring 26 to keep the fixing mechanism stable and provide a limiting effect for the film material, so that the two sleeves 16 fixedly connected to the sliding blocks 6 through the connecting blocks 17 also move closer inward, making the spraying range of the spraying holes 28 the same as the size of the laminated film material, and enabling the device to operate stably again.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
