[0002] Before valves leave the factory, in order to prevent wear and tear during transportation, plastic film is often wrapped around the valves. This is usually done manually, which is inefficient.

[0003] In related technologies, a wrapping device for a packaging machine is proposed, including a support, a cylinder, a pallet, and a rotating device. The cylinder is fixed to the upper end of the support, and the piston rod connected to the lower end of the cylinder is connected to the pallet through a fixing block. A film roll is provided at the upper end of the pallet, and a center rod is provided at the center of the film roll. A wrapping rod is provided on the side of the film roll away from the cylinder and is fixed to the pallet. A valve switch is also provided at the rear side of the support.

The support frame is fixed to the horizontal end of the support, and the turntable is provided at the upper end of the support frame. The support frame is connected to the motor through a shaft.

[0004] The aforementioned technologies have the following drawbacks: the device achieves film coating of the product through the tension between the film roll and the product. During the coating process, the product also needs to rotate. If the product is too tall, it is easy to tip over, resulting in low safety. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] This utility model provides a film-wound valve packaging device, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a support mechanism 1, a film covering mechanism 2, and a drive mechanism 3.

[0026] The support mechanism 1 includes a frame 11, a bracket 12, and a positioning rod 14. The bracket 12 is mounted on the frame 11 and is used to place the valve. The positioning rod 14 is used to insert into the center of the valve.

[0027] The coating mechanism 2 includes a support ring 21 and a support rod 22. The support ring 21 is mounted on the frame 11 and is coaxial with the support 12. The support rod 22 is mounted on the support ring 21 and is used to insert into the center of the film roll.

[0028] The drive mechanism 3 is used to drive the support ring 21 to rotate.

[0029] In use, the valve to be packaged is first placed on the bracket 12. The bracket 12 provides stable support for the valve, positioning it at a suitable height and position for subsequent film coating. The positioning rod 14 is inserted into the center of the valve to facilitate valve positioning and prevent valve shaking during the coating process. Then, the film roll is mounted on the support rod 22, allowing it to rotate freely for easy film pulling. The drive mechanism 3 then starts working, driving the support ring 21 to rotate around its axis. Since the support ring 21 is coaxial with the bracket 12, when the support ring 21 rotates, the support rod 22 on the support ring 21 also rotates, causing the film roll to rotate. The film pulled from the film roll gradually wraps around the valve surface on the bracket 12 as the support ring 21 rotates. With the continuous rotation of the support ring 21, the film is evenly wrapped around the valve layer by layer, continuously increasing the number of coating layers on the valve surface. When the predetermined number of wrapping turns or packaging requirements are reached, the drive mechanism 3 stops working.

[0030] In this invention, the driving mechanism 3 drives the film roll to rotate around the valve. At the same time, the film roll rotates on the support rod 22, thereby achieving the coating of the valve. During the coating process, the valve does not need to rotate. Moreover, since the film roll rotates around the valve, the tensile force of the film is small, which reduces the possibility of the valve tipping over and improves safety.

[0031] To improve the stability of the film roll, please refer to... Figure 1 In a preferred embodiment, a limit cap 23 is threaded onto the support rod 22, the limit cap 23 being used to restrict the movement of the film roll.

[0032] In use, after the film roll is placed on the support rod 22, the limiting cover 23 is rotated. Since the limiting cover 23 and the support rod 22 are threadedly connected, the limiting cover 23 will move axially along the support rod 22 under the action of the threads. As the limiting cover 23 moves towards the film roll, it gradually approaches one end face of the film roll. As the limiting cover 23 continues to rotate, it will eventually contact the end face of the film roll and generate compression. At this time, a constraint structure is formed between the limiting cover 23 and the support rod 22. The film roll is restricted in the axial direction by the limiting cover 23 and the structure on the support rod 22 near the other side of the film roll, and cannot move freely along the support rod 22. This effectively prevents the film roll from axially shifting on the support rod 22 due to centrifugal force, film tension, and other factors during the rotation of the support ring 21. This ensures that the film can be stably pulled out of the film roll and evenly wrapped around the valve, ensuring the smooth progress of the film wrapping and packaging process, and improving the stability and quality of the packaging.

[0033] To reduce friction between the film roll and the limiting cover 23, please refer to... Figure 2 In a preferred embodiment, a rotating ring 24 is rotatably connected to the bottom of the limiting cover 23.

[0034] During use, when the limiting cap 23 contacts and presses against the end face of the film roll to restrict its axial movement, a relative rotational frictional torque is generated on the bottom of the limiting cap 23 due to frictional force during the film roll's rotation. The rotating ring 24, rotatably connected to the bottom of the limiting cap 23, adapts to the relative movement between the film roll and the limiting cap 23 by its own rotation. The rotating ring 24 directly contacts and rotates relative to the film roll. Compared to the direct friction between the bottom of the limiting cap 23 and the film roll, the rotation of the rotating ring 24 significantly reduces friction and wear, allowing the film roll to rotate more smoothly on the support rod 22. This ensures that the film can be continuously, stably, and efficiently pulled from the film roll and wound onto the valve, extending the service life of the limiting cap 23 and the film roll, and also contributing to the continuous and stable operation of the entire film winding and packaging device.

[0035] To adjust the distance between the valve and the film roll and improve winding stability, please refer to... Figure 2 In a preferred embodiment, the support rod 22 is slidably connected to the support ring 21 along the radial direction of the support ring 21, and the support ring 21 is provided with a fixing component 4 for fixing the support rod 22.

[0036] In use, the support rod 22 slides radially along the support ring 21. Initially, the support rod 22 can slide freely radially along the support ring 21 according to the width of the film roll or different packaging requirements. Once the support rod 22 has slid to a suitable position, it is fixed in place by the fixing component 4 on the support ring 21. When the drive mechanism 3 drives the support ring 21 to rotate for film winding, the fixed support rod 22 stably supports the film roll. Because the position of the support rod 22 has been adjusted and fixed according to the film roll, the central axis of the film roll remains relatively stable during rotation, allowing the film pulled from the film roll to be wound evenly and smoothly onto the valve. The film roll will not wobble due to unstable position of the support rod 22, thus preventing any impact on the uniformity and quality of film winding. This ensures that the entire film winding and packaging process is efficient and stable, improving the effectiveness and efficiency of valve packaging.

[0037] To secure the support rod 22, please refer to... Figure 3 In a preferred embodiment, the fixing component 4 includes a socket 41, a rod 42, and a plurality of slots 43. The socket 41 is disposed on the support rod 22, the rod 42 is slidably connected to the socket 41, and the plurality of slots 43 are spaced apart on the support ring 21 along the sliding direction of the support rod 22.

[0038] In use, when it is necessary to adjust the radial position of the support rod 22 on the support ring 21, the operator first pulls the insert rod 42 out of the slot 43, allowing the support rod 22 to slide freely on the support ring 21. At this time, the support rod 22 can be moved to a suitable position radially along the support ring 21 according to the actual width of the film roll or packaging requirements. After the support rod 22 slides to the desired position, the insert rod 42 is inserted into the insertion hole 41 on the support rod 22, and the other end of the insert rod 42 is aligned with the corresponding slot 43 on the support ring 21. Since multiple slots 43 are spaced apart on the support ring 21 along the sliding direction of the support rod 22, the insert rod 42 can be inserted into different slots 43, thereby achieving the fixation of the support rod 22 in different positions.

[0039] To guide the insertion rod 42, please refer to... Figure 3 In a preferred embodiment, the end of the insert 42 near the support ring 21 is spherical.

[0040] In use, the spherical end allows the insertion rod 42 to slide more smoothly into the slot 43 on the support ring 21. This reduces jamming and resistance during insertion, allowing operators to more easily and quickly insert the insertion rod 42 accurately into the corresponding slot 43, thus improving the convenience and efficiency of fixing the support rod 22.

[0041] To improve the stability of pin 42, please refer to... Figure 3 In a preferred embodiment, a spring is fitted on the insertion rod 42, with one end of the spring connected to the insertion rod 42 and the other end connected to the support rod 22. The spring is in a stretched state, and the spring causes the insertion rod 42 to tend to slide towards the support ring 21.

[0042] During use, when the position of the support rod 22 is not adjusted, the insertion rod 42 is in a pre-tensioned state under the action of the spring. When it is necessary to adjust the radial position of the support rod 22 on the support ring 21, the operator overcomes the tension of the spring and pulls the insertion rod 42 outward, causing the insertion rod 42 to disengage from its current slot 43 or from its contact position with the surface of the support ring 21. At this time, the spring is further stretched, storing more elastic potential energy. When the support rod 22 reaches the new position, since the spring always has a tendency to make the insertion rod 42 slide towards the support ring 21, the operator only needs to release the insertion rod 42, and the insertion rod 42 will automatically slide towards the corresponding slot 43 on the support ring 21 under the restoring force of the spring. Since the end of the insertion rod 42 near the support ring 21 is spherical, it can smoothly enter the slot 43, ultimately achieving the purpose of inserting the insertion rod 42 into the slot 43 and fixing the support rod 22 on the support ring 21. This automatic insertion mechanism reduces the difficulty for operators to accurately align the slot 43 and insert the rod 42, improves the convenience and efficiency of the fixed support rod 22 operation, and also ensures that the rod 42 has a relatively stable insertion force each time it is inserted into the slot 43, thus enhancing the reliability of the fixation.

[0043] To drive the support ring 21 to rotate, please refer to... Figure 2 In a preferred embodiment, the drive mechanism 3 includes a power component 31 and a transmission component 32. The power component 31 includes a motor 311 mounted on the frame 11. The output shaft of the motor 311 is connected to the support ring 21 through the transmission component 32.

[0044] In use, the output shaft of motor 311 is connected to support ring 21 via transmission assembly 32. Transmission assembly 32 transmits the rotational power of motor 311's output shaft to support ring 21. As transmission assembly 32 transmits the power generated by motor 311 to support ring 21, support ring 21 begins to rotate uniformly around its axis. Since support ring 21 is coaxial with bracket 12, and support rod 22 is mounted on support ring 21 and used to hold film rolls, when support ring 21 rotates, support rod 22 also rotates, thereby driving the film roll placed on support rod 22 to rotate synchronously. As the film pulled from the film roll rotates, it gradually wraps around the valve surface placed on bracket 12 during the rotation of support ring 21, achieving film wrapping and packaging of the valve layer by layer until the predetermined number of wraps is reached or the packaging requirements are met.

[0045] To transmit the power generated by motor 311 to support ring 21, please refer to... Figure 2 In a preferred embodiment, the transmission assembly 32 includes a drive gear 321 disposed on the output shaft of the motor 311, and the support ring 21 is provided with a driven gear ring 322 that meshes with the drive gear 321.

[0046] In use, the driving gear 321 is mounted on the output shaft of the motor 311. As the output shaft of the motor 311 rotates, the driving gear 321 will synchronously perform circular motion. The driven gear ring 322 on the support ring 21 meshes with the driving gear 321. As the driven gear ring 322 begins to rotate under the drive of the driving gear 321, the support ring 21 will synchronously rotate around its own axis because the driven gear ring 322 is mounted on the support ring 21. Since the support ring 21 is coaxial with the bracket 12, and the support rod 22 is mounted on the support ring 21 to hold the film roll, when the support ring 21 rotates, the support rod 22 also rotates, thereby driving the film roll placed on the support rod 22 to rotate synchronously. The film pulled from the film roll will gradually wrap around the valve surface placed on the bracket 12 during the rotation of the support ring 21, thereby realizing the film wrapping and packaging operation of the valve.

[0047] To improve valve stability, please refer to... Figure 2 In a preferred embodiment, the top of the bracket 12 is provided with an anti-slip layer 13.

[0048] During use, the anti-slip layer 13 has a special surface texture or material properties that significantly increase the friction between it and the bottom contact surface of the valve. When the valve is placed on top of the bracket 12, compared to the case without the anti-slip layer 13, the greater friction makes it less likely for the valve to slide or shift on the bracket 12 when subjected to external forces. This ensures that the valve is always in the correct position, providing a stable foundation for the film winding operation and ensuring that the film can be wound evenly and accurately on the valve surface.

[0049] To better understand this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of a film-wrapping valve packaging device according to this utility model is described in detail below: First, the valve to be packaged is placed on the support 12. The support 12 provides stable support for the valve, placing it at a suitable height and position for subsequent film coating operations. Then, the film roll is installed on the support rod 22, which allows the film roll to rotate freely, facilitating the pulling out of the film. The drive mechanism 3 starts working, driving the support ring 21 to rotate around its axis. Since the support ring 21 is coaxial with the support 12, when the support ring 21 rotates, the support rod 22 on the support ring 21 also rotates, causing the film roll to rotate. The film pulled from the film roll gradually wraps around the valve surface on the support 12 during the rotation of the support ring 21. As the support ring 21 continues to rotate, the film is evenly wrapped around the valve layer by layer, continuously increasing the number of coating layers on the valve surface. When the predetermined number of wrapping turns or packaging requirements are reached, the drive mechanism 3 stops working.

[0050] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
