Description

Technical Field

[0001] This utility model relates to the field of can sealing technology, and in particular to a can sealing film device. Background Technology

[0002] In the bottling process of food, beverage, and chemical industries, sealing is a key step in ensuring product quality and extending shelf life. Its efficiency and sealing quality directly affect the company's production benefits and product market competitiveness. Currently, bottling sealing devices on the market are mainly divided into two categories: manual-assisted and semi-automatic. However, there are still many problems that need to be solved in practical applications.

[0003] While existing semi-automatic sealing devices can achieve mechanical drive in some stages, they still have significant shortcomings. On the one hand, most devices lack stable sealing film guidance and residual film recovery structures. During the conveying process, the sealing film is prone to wrinkles and deviations due to pulling, which not only affects the sealing quality but also causes a large amount of residual film to accumulate or be discarded at will, resulting in low sealing film utilization and a significant increase in consumable costs in the long run. On the other hand, the sealing actuators of some devices lack precise guiding constraints, and the sealing components are prone to lateral swaying during lifting and lowering, resulting in uneven sealing pressure at the can opening and making it difficult to ensure the consistency of sealing quality for each can.

[0014] (III) Beneficial Effects

[0015] This utility model provides a sealing film device for cans. It has the following beneficial effects:

[0016] 1. By working in coordination with the drive motor, the rewinding shaft can synchronously recover the excess film after sealing according to the film release rate and sealing rhythm, avoiding waste caused by random discarding or accumulation of film. Long-term use can significantly reduce the cost of film consumables.

The electric push rod A drives the two sealing frames to operate synchronously, completing the sealing of two cans in a single operation, significantly shortening the processing time for a single batch. Simultaneously, the guide rod strictly constrains the lifting trajectory of the support plate, and the through-slot further assists in aligning the sealing frames with the can openings, effectively preventing sealing misalignment and ensuring consistent sealing performance for each can. This reduces rework due to sealing quality issues and guarantees the quality stability of mass production. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Reference Figures 1 to 4As shown, this utility model provides a technical solution: a can sealing film device, including a processing table 1, a support frame 2 fixedly connected to the surface of the processing table 1, a fixing block 4 fixedly connected to the top of the support frame 2, a rotating shaft 5 rotatably connected to one side of the fixing block 4, a sealing film roll 6 provided on the surface of the rotating shaft 5, and an auxiliary rotating roller A7 provided below the rotating shaft 5. An auxiliary rotating roller B8 is arranged parallel to the end of the support frame 2 away from the auxiliary rotating roller A7, and a winding shaft 9 is provided above the auxiliary rotating roller B8. A fixed top plate 11 is fixedly connected to the main body. An electric push rod A12 is installed on the lower surface of the fixed top plate 11. A bearing plate 13 is fixedly connected to the output end of the electric push rod A12. Two sealing frames 17 are provided on the lower surface of the bearing plate 13. The support frame 2 fixed to the surface of the processing table 1 provides stable support for the overall structure. The rotating shaft 5 rotatably connected to the top fixed block 4 can reliably support and position the sealing film roll 6, ensuring that the sealing film roll 6 can rotate smoothly to release the sealing film. An auxiliary rotating roller A is set below the rotating shaft 5. The auxiliary roller B, positioned parallel to the end of the support frame 2 furthest from the auxiliary roller A, forms a continuous sealing film guide path. This guides the sealing film released from the sealing film roll 6, effectively preventing wrinkles and misalignment during transport and ensuring the stability and consistency of the sealing film delivery. Simultaneously, the take-up shaft 9 above the auxiliary roller B allows for timely recovery of excess film after sealing, reducing waste and achieving film-saving effects, thus lowering production costs. During sealing, the fixed top plate 11, fixedly connected to the top of the support frame 2, provides a stable mounting base for the electric push rod A. The bearing plate 13, fixedly connected to the output end of the electric push rod A, can be precisely raised and lowered under the drive of the electric push rod A. The two sealing frames 17 on the lower surface of the bearing plate 13 rise and fall synchronously with the bearing plate 13, enabling simultaneous sealing of two containers, significantly improving sealing efficiency. Furthermore, the entire sealing execution structure, with the fixed top plate 11 and the electric push rod A... In conjunction with the support plate 13, the accuracy of the lifting trajectory of the sealing frame 17 can be ensured, avoiding positional deviation of the sealing frame 17 during the sealing process, and ensuring the sealing performance and reliability of the sealing operation.

[0026] Reference Figure 3 and Figure 4As shown, in this embodiment: a drive motor 10 is provided on one side of the winding shaft 9, and the drive motor 10 is mounted on the top of the support frame 2. Side plates 3 are provided on both sides of the support frame 2, and a support plate 14 is fixedly connected between the two side plates 3. The support plate 14 is located below the bearing plate 13, and two through slots 16 are formed on the surface of the support plate 14. Guide rods 15 are slidably connected to the four corners of the bearing plate 13, and the lower ends of the four guide rods 15 are fixedly connected to the surface of the support plate 14. The drive motor 10 is mounted on the top of the support frame 2. The motor 10 provides a stable power source for the take-up shaft 9, and can precisely control the rotation speed and start / stop status of the take-up shaft 9, so that the take-up shaft 9 can keep in sync with the film release rate and sealing operation rhythm. At the same time, the side plates 3 set on both sides of the support frame 2 can provide lateral protection for the device, effectively preventing foreign objects from entering and affecting the operation of the components, and improving the safety of the device operation. The support plate 14 fixedly connected between the two side plates 3, together with the two through slots 16 opened on the surface, can allow the two sealing frames 17 on the lower surface of the carrier plate 13 to accurately pass through the through slots 16 under the drive of the electric push rod A and act on the tank to be sealed, providing a working guide channel for the sealing frames 17 and ensuring that the sealing operation is accurately applied to the tank opening position. In terms of precise sealing guidance, the guide rods 15, which are slidably connected at the four corners of the carrier plate 13 and fixed to the surface of the support plate 14 at the lower end, can strictly limit the lifting trajectory of the carrier plate 13 and avoid lateral deviation or shaking of the carrier plate 13 during the lifting and lowering process driven by the electric push rod A.

[0027] Reference Figure 1 , Figure 2 and Figure 4As shown, specifically, two fixed plates 18 are provided below the support plate 14, and a sliding plate 19 is slidably connected between the two fixed plates 18. Two placement grooves 20 are formed on the surface of the sliding plate 19. A mounting base 21 is provided at one end of each fixed plate 18, and an electric push rod B22 is mounted on the surface of the mounting base 21. The output end of the electric push rod B22 is fixedly connected to the lower surface of the sliding plate 19. A switch controller 23 is provided on the surface of the processing table 1. The switch controller 23 is electrically connected to the drive motor 10, the electric push rod A12, and the electric push rod B22. The sliding plate 19, slidably connected between the two fixed plates 18 below the support plate 14, facilitates tank positioning and stable load bearing. The two placement slots 20 on its surface can accurately position and stably support two cans to be sealed, effectively limiting the lateral displacement and shaking of the cans during the sealing process. At the same time, it can be adapted to canned products of corresponding specifications, improving the adaptability of the device to specific cans. In terms of can conveying drive, the electric push rod B on the surface of the mounting base 21 at one end of the fixed plate 18 is fixedly connected to the lower surface of the sliding plate 19, which can provide stable linear drive power to the sliding plate 19, realizing the accurate conveying of the cans to be sealed to the sealing area and the smooth movement of the cans to the material picking area after sealing. Meanwhile, the switch controller 23 on the surface of the processing table 1 is electrically connected to the drive motor 10, electric push rod A and electric push rod B, which can ensure precise coordination of each action link, avoid action delay or coordination deviation caused by manual operation of each component, further improve the stability and reliability of the device operation, and simplify the operation process, reducing the dependence on the professional skills of the operators.

[0028] Working Principle: First, the device uses the support frame 2 fixed on the surface of the processing table 1 as a stable support base. The sealing film roll 6 is fitted onto the rotating shaft 5 rotatably connected to the fixed block 4 at the top of the support frame 2, completing the initial preparation for sealing film supply. At this time, the operator starts the device through the switch controller 23 on the surface of the processing table 1, and the drive motor 10 starts to run, providing stable power to the take-up shaft 9, causing the take-up shaft 9 to rotate synchronously, thereby pulling the sealing film roll 6 on the rotating shaft 5 to release the sealing film. The sealing film is conveyed smoothly, stably, and without deviation in the continuous guide path formed by the auxiliary rotating roller A below the rotating shaft 5 and the auxiliary rotating roller B set parallel to the other end of the support frame 2, continuously supplying sealing film to the sealing operation area. At the same time, the operator places two cans to be sealed into the two placement slots 20 on the surface of the sliding plate 19 slidably connected between the two fixed plates 18 below the support plate 14. The placement slots 20 accurately position and stably support the cans, preventing the cans from shifting. The electric push rod B is started by controlling the switch controller 23. The output power drives the sliding plate 19 to slide along the fixed plate 18, accurately conveying the can to be sealed to the area directly below the support plate 14, ensuring that the can opening aligns perfectly with the two through slots 16 on the surface of the support plate 14, thus completing the pre-sealing positioning and conveying of the can. Subsequently, the switch controller 23 activates the electric push rod A. The guide rods 15, which are slidably connected to the four corners of the drive plate 13, move precisely downwards. The two sealing frames 17 set on the lower surface of the drive plate 13 descend synchronously with the drive plate 13 and pass through the two through slots 16 on the surface of the support plate 14, precisely acting on the sealing film of the can to be sealed below, realizing the synchronous sealing operation of the two cans. During this process, the guide rods 15 strictly limit the lifting trajectory of the drive plate 13 to avoid lateral deviation or shaking of the sealing frames 17, ensuring the sealing performance and reliability. At the same time, the side plates 3 on both sides of the support frame 2 provide lateral protection for the internal operating parts of the device, improving operational safety. While the sealing operation is in progress, the winding shaft 9, under the continuous drive of the drive motor 10, always maintains a rotation speed that matches the film release rate and sealing operation rhythm, timely and stably recovering the excess film generated after the sealing operation, reducing film waste and achieving film-saving effect. After the sealing operation is completed, the switch controller 23 controls the electric push rod A to drive the carrier plate 13 to move the sealing frame 17 upward to reset, and then controls the electric push rod B to drive the sliding plate 19 to slide along the fixed plate 18, so that the sealed can is smoothly moved out to the material picking area. After the operator takes off the finished can, the above process of placing, conveying and sealing the can can be repeated to achieve batch continuous operation.
