Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The present disclosure can also be implemented or applied through other different specific implementation manners.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure. Embodiment

[0025] As Figures 1-4 shown, the present utility model provides a continuous film - placing mechanism for tank packaging, including a substrate 1 for supporting equipment components, a conveyor belt 2 disposed on one side of the substrate 1 for conveying tanks, and a first support frame 16 on one side of the conveyor belt 2. It further includes a film - storing structure for placing films, a film - taking structure for taking out films from the film - storing structure, a film - conveying structure for transferring the films to the next process, and a film - pressing structure for placing the films inside the tanks.

[0026] The substrate 1 bears components such as the conveyor belt 2, the support frame, the film - storing structure, the film - taking structure, the film - conveying structure, and the film - pressing structure, providing a stable support platform to ensure the smoothness and reliability of the mechanism during operation.

[0027] The conveyor belt 2 is disposed on one side of the substrate 1 and is responsible for continuously and smoothly conveying the tanks to be packaged to the designated position. Through the movement of the conveyor belt 2, the automatic conveying of the tanks is realized, improving the packaging efficiency.

[0028] By integrating multiple structures such as film storage, film retrieval, film feeding, and film pressing, a fully automated process for the film from storage to final pressing into the tank body is achieved, reducing the burden of manual operation, greatly improving the packing efficiency, and lowering the labor cost.

[0029] The film retrieval structure and the film feeding structure ensure that a film can be accurately retrieved from the film storage structure and accurately conveyed above the tank body or to a specified position. The film pressing structure further ensures that the film can be accurately placed inside the tank body, avoiding problems such as film misalignment and improving the packing accuracy and quality.

[0030] The continuous movement of the conveyor belt 2 enables the tank body to be continuously conveyed to the packing position, and the close cooperation of the film storage structure, film retrieval structure, film feeding structure, and film pressing structure ensures that the film can be quickly and accurately placed inside the tank body. This continuous and efficient working mode greatly improves the packing efficiency of the tank body.

[0031] See Figure 1 and Figure 4 As shown in

[0032] The baffle 3 and the limiting member 4 are provided in the film storage structure. A lifting plate for lifting the film is provided at the bottom of the space formed by the baffle 3 and the limiting member 4, and a pressure assembly 6 for pressing the film is provided above the limiting member 4.

[0033] The baffle 3 and the limiting member 4 jointly enclose a semi-closed space for storing the film materials to be used. This space ensures the neatness and orderliness of the film during storage.

[0034] The lifting plate is located at the bottom of the space formed by the baffle 3 and the limiting member 4 and can move up and down. When the film needs to be retrieved, the lifting plate will rise to lift the film from the storage position, facilitating the subsequent film retrieval operation.

[0035] The presence of the lifting plate enables the film retrieval structure to more easily grab the film, thereby improving the accuracy and efficiency of film retrieval.

[0036] The pressure assembly 6 is provided above the limiting member 4 and is used to press the film after it is lifted to a certain height. This step can ensure that only one film is retrieved when taking out the film, facilitating the subsequent film feeding and film pressing operations.

[0037] See Figure 4, the baffle 3 is provided with a first threaded shaft 21. On one side of the first threaded shaft 21, a second motor 23 is provided. A chain gear set 24 is connected between the rotor of the second motor 23 and the first threaded shaft 21. The first threaded shaft 21 is in threaded connection with the lifting plate. By operating the second motor 23 to rotate, the first threaded shaft 21 is driven to control the horizontal height of the lifting plate.

[0038] The first threaded shaft and the lifting plate are in threaded connection to ensure the stability of the lifting plate during the lifting process. At the same time, the threaded connection has high precision and can achieve precise adjustment of the height of the lifting plate.

[0039] The second motor 23 serves as a power source and transmits power through the chain gear set 24 between the rotor and the first threaded shaft 21 to drive the first threaded shaft 21 to rotate. Since the rotation speed and direction of the second motor 23 can be precisely controlled, the lifting speed and direction of the lifting plate can be precisely controlled.

[0040] The control system performs automatic control on the second motor 23, which can realize the automatic management of the lifting process of the lifting plate, reduce the need for manual intervention, and improve the automation degree of the entire packaging process.

[0041] During the process of the lifting plate lifting the film, due to the stable supporting effect of the first threaded shaft 21 and the lifting plate, it can be ensured that the film will not shake or slip during the movement.

[0042] See Figure 1 , the film taking structure is provided with a first cylinder 7 and a vacuum generator. The movable end of the first cylinder 7 is arranged downward. A horizontal connecting frame is arranged at the movable end. A suction nozzle 8 for sucking the film is fixed on the connecting frame. The first cylinder 7 drives the connecting frame to control the up and down movement of the suction nozzle 8, and the suction nozzle 8 pumps air to suck the film.

[0043] The first cylinder 7 serves as a power source. Its movable end is arranged downward. A suction nozzle 8 for sucking the film is fixed through a horizontal connecting frame. By controlling the telescopic movement of the first cylinder 7, the position of the suction nozzle 8 in the vertical direction can be precisely controlled to ensure that the suction nozzle 8 can accurately contact the surface of the film to be sucked.

[0044] The vacuum generator generates negative pressure, and a negative pressure environment is formed inside the suction nozzle 8 through air pumping. When the suction nozzle 8 contacts the film surface, the negative pressure environment will quickly adsorb the film on the suction nozzle 8, realizing the rapid and stable suction of the film. This suction method is more efficient and reliable than the traditional mechanical grasping method, avoiding problems such as film damage or misalignment caused by improper grasping.

[0045] Due to the strong adsorption capacity of the negative pressure environment generated by the vacuum generator, it can adapt to films of different materials and thicknesses, making the continuous film feeding mechanism of the tank body packaging more flexible and reliable when dealing with different types of film packaging tasks.

[0046] During the suction process, since the contact between the suction nozzle 8 and the film is a gentle negative pressure adsorption effect, mechanical damage or scratches to the film can be avoided. At the same time, since the suction nozzle 8 can precisely control the position and force, it can ensure that only one film is sucked during the suction process, thus guaranteeing the smooth progress of subsequent packaging operations.

[0047] See Figure 1 、 Figure 2 and Figure 3 As shown in

[0048] The film feeding structure is provided with a first motor 20. The rotor end of the first motor 20 is connected to a second threaded shaft 22. A track 9 is arranged below the second threaded shaft 22. A slider 10 is sleeved on the second threaded shaft 22. The slider 10 is slidably connected to the track 9. The slider 10 is fixedly connected to a fixing plate 11. The first cylinder 7 is fixedly connected to the fixing plate 11. The first motor 20 drives the second threaded shaft 22 to rotate to control the movement of the slider 10 threadedly connected to the second threaded shaft 22, thereby controlling the translation of the suction nozzle 8 to complete the film feeding step.

[0049] The cooperation between the first motor 20 and the second threaded shaft 22. The second threaded shaft 22 connected to the rotor end of the first motor 20 drives the slider 10 sleeved on it to move through rotation. Since the slider 10 and the second threaded shaft 22 are threadedly connected, the movement distance of the slider 10 can be precisely controlled by controlling the rotation angle and speed of the first motor 20, thereby realizing the precise control of the film feeding distance.

[0050] Threaded connection has self-locking property, which can keep the position of the slider 10 unchanged after the first motor 20 stops rotating, thereby ensuring the stability of the suction nozzle 8 and the film during the film feeding process, reducing the offset or jitter of the film during movement, and improving the accuracy and reliability of film feeding.

[0051] See Figure 1, the film pressing structure is provided with a placement table 12 and a second support frame 19 on one side of the placement table 12. The placement table 12 is provided with a through hole 13, and the second support frame 19 extends above the through hole 13. A second cylinder 14 is arranged directly above the through hole 13, and a third cylinder 15 is arranged directly above the outside of the through hole 13. Both the second cylinder 14 and the third cylinder 15 are fixedly connected to the second support frame 19, and the movable ends of the second cylinder 14 and the third cylinder 15 pass through the second support frame 19 and are connected with a pressing block 17.

[0052] The placement table 12 is used to carry the delivered film. The through hole 13 opened thereon allows the pressing block 17 to pass through the through hole 13 and extend into the tank body for pressing, so as to press the film into the tank body. After the film is delivered to the placement table 12, the pressing block 17 at the movable end of the third cylinder 15 presses down to fix the film, and then the pressing block 17 at the movable end of the second cylinder 14 presses down the film into the tank body. When the pressing block 17 at the movable end of the second cylinder 14 descends to the through hole 13, the pressing block 17 at the movable end of the third cylinder 15 lifts, completing the film placing action of the tank body. Through the coordinated action of the second cylinder 14 and the third cylinder 15, the pressing block 17 can apply sufficient pressure to ensure that the film is accurately placed into the tank body.

[0053] The operation of the film pressing structure can be automatically controlled through the control system, and it works in coordination with other components such as the film feeding structure to realize the automation of the entire packaging process, which not only improves the production efficiency, but also reduces the complexity and error rate of manual operation.

[0054] See Figure 1 , the through hole 13 is a circular through hole 13 with rounded corners, and the area of the through hole 13 is larger than the bottom area of the pressing block 17.

[0055] Through the rounded corner treatment, the stress can be dispersed, the strength and durability of the edge of the through hole 13 can be improved, and the cracking or damage phenomenon caused by stress concentration during use can be prevented.

[0056] The rounded corner treatment makes the edge of the through hole 13 smoother, which is beneficial to the more uniform and stable contact between the pressing block 17 and the edge of the through hole 13 during the pressing process. This helps to achieve the uniform distribution of the film in the tank body and improve the film pressing effect.

[0057] The design that the area of the through hole 13 is larger than the bottom area of the pressing block 17 ensures that the pressing block 17 can completely enter the through hole 13 during the descending process and maintain sufficient contact area with the edge of the through hole 13. This is beneficial to achieve more stable and uniform pressing force transmission and ensure that the film can be tightly attached to the inner wall of the tank body.

[0058] See Figure 1 , the shape of the pressing block 17 connected to the movable end of the second cylinder 14 is a frustum of a cone in a positive position.

[0059] The frustum-shaped design enables the pressing block 17 to have a larger contact area when contacting the film, which helps to distribute the pressing force more evenly on the film and prevent the film from being damaged or deformed due to excessive local pressure.

[0060] Due to the increased contact area between the frustum-shaped pressing block 17 and the film, and the reasonable shape design, the relative sliding between the pressing block 17 and the film during the pressing process can be reduced.

[0061] See Figure 1 , the first cylinder 7 and the second cylinder 14 are threadedly connected to the pressing block 17.

[0062] When the first cylinder 7 and the second cylinder 14 are threadedly connected to the pressing block 17, during installation, only need to align the threads on the pressing block 17 with the threads at the movable end of the cylinder and tighten them; when disassembly is required, only need to rotate the threads in the reverse direction to easily separate. This installation method not only improves work efficiency but also reduces maintenance costs.

[0063] Due to the adjustability of the threaded connection, the appropriate pressing block 17 can be selected according to different working requirements.

[0064] See Figure 1 and Figure 2 , the conveyor belt 2 is provided with a movable limit block 18 for positioning the tank body. The movable limit block 18 is arranged below the placement table 12. The movable limit block 18 extends out to block the movement of the tank body and descends after the film placement step is completed.

[0065] The movable limit block 18 is arranged below the placement table 12. When the tank body is conveyed to the designated position, the movable limit block 18 can extend out to block the further movement of the tank body. This can ensure that each tank body is accurately placed on the placement table 12, providing an accurate position basis for the subsequent film placement and film pressing steps.

[0066] Through the positioning function of the movable limit block 18, problems such as film placement deviation or uneven film pressing caused by inaccurate tank body position can be reduced, improving the accuracy and consistency of packaging.

[0067] During the film placement step, the movable limit block 18 remains extended, which can fix the position of the tank body and prevent it from moving or tilting during the film placement process.

[0068] Since the movable limit block 18 can automatically position and fix the tank body, the need for manual intervention can be reduced, which not only reduces the labor intensity but also reduces errors and failure rates caused by improper manual operation.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0070] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. The meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
