Description

Technical Field

[0001] This utility model relates to the field of packaging sealing, and more particularly to sealing devices for packaging equipment. Background Technology

[0002] Packaging sealing refers to the operation of sealing the opening of a packaging container after the product is placed inside. The main purpose of sealing is to ensure that the contents remain in the container during transportation, storage and sales, and to avoid contamination and damage. Packaging is a necessary condition for products to enter the circulation field. In the packaging process, a sealing device is usually used, mainly to seal packaging bags or other containers to prevent the contents from leaking or being contaminated by the outside world.

[0003] Currently, the sealing devices used in packaging equipment have relatively low fixing force on the product during operation, and the product is prone to displacement during the sealing process, which affects the flatness and appearance of the seal and is not conducive to improving product processing quality.

[0004] Therefore, since the sealing device used in the above-mentioned packaging equipment has low fixing force on the product, the product is prone to displacement during the sealing process, which affects the flatness and aesthetics of the seal and is not conducive to improving the product processing quality, a sealing device for packaging equipment with a clamping and stabilizing mechanism can be designed. Utility Model Content

[0005] To overcome the problem that the sealing device used in packaging equipment has low fixing force on the product during operation, the product is prone to displacement during the sealing process, which affects the flatness and appearance of the seal and is not conducive to improving the product processing quality.

[0006] The technical solution of this utility model is as follows: a sealing device for packaging equipment, including an operating table and a mounting frame. A telescopic cylinder is fixedly installed on the upper end of the mounting frame. The output end of the telescopic cylinder extends to the inner side of the mounting frame and a heat sealing plate is fixedly installed thereon. An electric displacement guide rail is fixedly installed on the upper end of the operating table, located inside the mounting frame. A connector is provided on the electric displacement guide rail. A double-work displacement plate is fixedly installed on the connector. Workbenches are fixedly installed on the left and right sides of the upper end of the double-work displacement plate. Connecting sleeves are fixedly installed on the front and rear sides of the upper end of the workbenches. A lifting block is provided inside the connecting sleeve. A lifting rod is fixedly installed on the upper end of the lifting block. A connecting plate is fixedly installed on the upper end of the lifting rod, extending to the outer side of the connecting sleeve. A return spring is provided on the surface of the lifting rod. A fixing clamp is fixedly installed on the lower end of the connecting plate.

[0007] Preferably, the return spring can pull the connecting plate downward through its own elastic contraction, so that the fixing clamp tightly holds the product and prevents the product from shifting on the worktable. When the heat sealing plate seals the product on one side of the worktable, the other side of the worktable can be loaded and unloaded at the same time. The electric displacement guide rail can adjust the position of the double-station displacement plate, so that the processed product moves to the upper and lower areas, and the fixed product moves to the sealing processing area, thereby realizing the reciprocating cycle of double-station alternating work. The support slide rod and sliding block can assist the operation of the double-station displacement plate, improve the stability of the movement of the double-station displacement plate, and provide longitudinal support to protect the electric displacement guide rail.

[0008] As a preferred option, the mounting bracket has a U-shaped structure design, the output end of the telescopic cylinder is slidably connected to the mounting bracket, and the heat sealing plate is compatible with the worktable.

[0009] Preferably, auxiliary sliding seats are fixedly installed on both the front and rear sides of the double displacement plate at the upper end of the operating table. A support slide rod is fixedly installed inside the auxiliary sliding seat, and a sliding block is provided on the surface of the support slide rod.

[0010] Preferably, the support slide rod is slidably connected to the slide block, the slide block is slidably connected to the auxiliary slide seat, and the slide block is fixedly connected to the duplex displacement plate.

[0011] Preferably, a limit plate is fixedly installed on the upper end of the workbench on the side of the fixed clamping plate, and a pull rod is fixedly installed on the upper end of the connecting plate.

[0012] Preferably, the surface of the lifting block is slidably connected to the connecting sleeve, and the surface of the lifting rod is slidably connected to the connecting sleeve.

[0013] Preferably, the return spring and the lifting rod are sleeved together, one end of the return spring is fixedly connected to the connecting sleeve, and the other end of the return spring is fixedly connected to the connecting plate.

[0014] The beneficial effects of this utility model are:

[0015] The sealing device in this packaging equipment utilizes the elastic contraction of a return spring to pull the connecting plate downwards, allowing the fixing clamp to tightly hold the product, preventing the product from shifting on the worktable. This facilitates a smooth and aesthetically pleasing seal by the heat-sealing plate, ensuring high-quality product processing. While the heat-sealing plate is sealing products on one side of the worktable, loading and unloading operations can be performed simultaneously on the other side. The electric displacement guide rail drives the double-station displacement plate to move the processed products to the upper and lower areas, while the fixed products move to the sealing processing area. This achieves a reciprocating cycle of alternating double-station operation, improving the working efficiency of the sealing device in the packaging equipment. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a sealing device for packaging equipment, including an operating table 1 and a mounting frame 2. A telescopic cylinder 3 is fixedly installed on the upper end of the mounting frame 2. A heat sealing plate 4 is fixedly installed on the output end of the telescopic cylinder 3 extending to the inner side of the mounting frame 2. An electric displacement guide rail 5 is fixedly installed on the upper end of the operating table 1 located inside the mounting frame 2. A connecting piece 6 is provided on the electric displacement guide rail 5. A double-work displacement plate 7 is fixedly installed on the connecting piece 6. Workbenches 8 are fixedly installed on the left and right sides of the upper end of the double-work displacement plate 7. Connecting sleeves 9 are fixedly installed on the front and rear sides of the upper end of the workbenches 8. A lifting block 10 is provided inside the connecting sleeve 9. A lifting rod 11 is fixedly installed on the upper end of the lifting block 10. A connecting plate 12 is fixedly installed on the upper end of the lifting rod 11 extending to the outer side of the connecting sleeve 9. A return spring 13 is provided on the surface of the lifting rod 11. A fixing clamp 14 is fixedly installed on the lower end of the connecting plate 12.

[0024] Please see Figures 1-3In this embodiment, the mounting frame 2 has a U-shaped structure design. The output end of the telescopic cylinder 3 is slidably connected to the mounting frame 2. The heat sealing plate 4 is adapted to the worktable 8. The upper end of the operating table 1 is fixedly installed with auxiliary sliding seats 15 on both the front and rear sides of the double-work displacement plate 7. The auxiliary sliding seat 15 has a support slide rod 16 fixedly installed inside. The surface of the support slide rod 16 is provided with a sliding block 17. The support slide rod 16 is slidably connected to the sliding block 17. The sliding block 17 is slidably connected to the auxiliary sliding seat 15. The sliding block 17 is fixedly connected to the double-work displacement plate 7. When the heat sealing plate 4 seals the product on one side of the worktable 8, the other side of the worktable 8 can simultaneously perform loading and unloading operations. When the sealing is completed, the double-work displacement plate 7 is moved by the electric displacement guide rail 5, so that the processed product moves to the upper and lower areas, and the fixed product moves to the sealing processing area, thereby realizing the reciprocating cycle of double-workstation alternating work, which is conducive to improving the working efficiency of the sealing device for packaging equipment.

[0025] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, a limiting plate 18 is fixedly installed on the side of the fixed clamping plate 14 at the upper end of the workbench 8. A pull rod is fixedly installed on the upper end of the connecting plate 12. The surface of the lifting block 10 is slidably connected to the connecting sleeve 9. The surface of the lifting rod 11 is slidably connected to the connecting sleeve 9. The return spring 13 is sleeved with the lifting rod 11. One end of the return spring 13 is fixedly connected to the connecting sleeve 9, and the other end of the return spring 13 is fixedly connected to the connecting plate 12. The product is placed on the workbench 8, and the section to be sealed is pressed against the limiting plate 18. The pull rod is released, and the elastic contraction of the return spring 13 pulls the connecting plate 12 downward, so that the fixed clamping plate 14 tightly clamps the product, preventing the product from shifting on the workbench 8. This facilitates the heat sealing plate 4 to seal the product smoothly, making the seal flat and beautiful, and ensuring the processing quality of the product.

[0026] During operation, the pull rod is first pulled upward to raise the fixed clamping plate 14, making it easier to place the product on the worktable 8 and make the section to be sealed press against the limiting plate 18. The pull rod is then released, and the elastic contraction of the return spring 13 pulls the connecting plate 12 downward, so that the fixed clamping plate 14 tightly clamps the product, preventing the product from shifting on the worktable 8. While the heat sealing plate 4 is sealing the product on one side of the worktable 8, the other side of the worktable 8 can be loaded and unloaded at the same time. When the sealing is completed, the electric displacement guide rail 5 drives the double-station displacement plate 7 to move, so that the processed product moves to the upper and lower areas, and the fixed product moves to the sealing processing area, thereby realizing the reciprocating cycle of double-station alternating work.

[0027] Through the above steps, the elastic contraction of the return spring 13 pulls the connecting plate 12, so that the fixing clamp 14 tightly clamps the product and prevents the product from shifting. This solves the problem that the sealing device of the packaging equipment has low fixing force on the product when it is working, and the product is prone to shifting during the sealing process, which affects the flatness and appearance of the seal and is not conducive to improving the product processing quality.
