[0002] Transfer devices are generally used in industrial production or automation systems to move materials, products, parts or workpieces from one location to another. In the production process of plastic film, when the film is transferred between different devices, the material handling needs to be completed quickly and efficiently. In order to improve the speed and accuracy of handling, maintain the continuous operation of the production line, and avoid production bottlenecks, plastic film roll transfer devices are needed.
[0003] Plastic film roll transfer devices can be divided into several types, namely roller transfer devices, belt conveyor transfer devices, and forklift transfer devices. Depending on the weight and size of the film roll and the needs of the production line, different types of plastic film roll transfer devices can be selected. Among them, forklift transfer devices are usually equipped with mechanical forks, which use electric or hydraulic drive to transfer the film roll from one position to another.
[0004] While existing technologies can provide basic transfer functions, in practical applications, transfer devices are prone to misalignment or detachment when installing film rolls. This is especially true when installing large or heavy film rolls, where traditional devices often struggle to maintain stable clamping force, making it difficult to secure the film roll. Furthermore, the significant differences in operator height mean that traditional devices cannot provide a comfortable working height for all operators, causing inconvenience. Therefore, improving the stability and convenience of film roll installation and avoiding the risks of misalignment and detachment has become an urgent problem to be solved. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a plastic film roll transfer device, which aims to improve the problem that the film roll is easily misaligned or even falls off when it is directly installed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a plastic film roll transfer device, including a base plate, a bracket fixedly connected to the top of the base plate, a main shaft fixedly connected to one side of the bracket, and an installation assembly provided inside the main shaft;
[0007] The mounting assembly includes a threaded rod rotatably connected inside the main shaft. A limiting groove is formed inside the main shaft. An outer conical barrel is threadedly connected to the outer wall of the threaded rod. The outer conical barrel is slidably connected inside the limiting groove. A limiting component is provided on the outer wall of the main shaft. Multiple clamping plates are arranged in a circular array on the outer wall of the main shaft. An inner conical plate is fixedly connected to the inner wall of the clamping plate. The inner wall of the inner conical plate fits against the outer wall of the outer conical barrel.

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the threaded rod is first rotated to drive the outer cone barrel to move within the main shaft.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a plastic film roll transfer device, comprising a base plate 1, a bracket 2 fixedly connected to the top of the base plate 1, and a main shaft 3 fixedly connected to one side of the bracket 2. The main shaft 3 contains an installation assembly. The base plate 1 serves as a supporting structure for the device, stabilizing the overall position and ensuring the stability and accuracy of each component during operation. The bracket 2 provides support and connects the main mechanical components, supporting the entire device structure. The main shaft 3, as a key component, interacts with other components through a rotation and sliding mechanism to ensure the correct installation and stable transfer of the film roll.
[0030] The mounting assembly includes a threaded rod 4, which is rotatably connected inside the main shaft 3. A limiting groove 5 is formed inside the main shaft 3. An outer conical barrel 6 is threadedly connected to the outer wall of the threaded rod 4, and the outer conical barrel 6 is slidably connected inside the limiting groove 5. The connection between the threaded rod 4 and the main shaft 3 ensures stability during rotation and effectively drives the outer conical barrel 6 to move within the main shaft 3. The outer conical barrel 6 is threadedly connected to the threaded rod 4, allowing precise control of its movement and ensuring it slides within the limiting groove 5 of the main shaft 3. This design ensures that the range of motion of the outer conical barrel 6 is limited, effectively preventing excessive sliding and guaranteeing stability and accuracy during film roll mounting. A limiting assembly is provided on the outer wall of the main shaft 3, and multiple clamping plates 8 are arranged in a circular array on the outer wall of the main shaft 3. An inner conical plate 9 is fixedly connected to the inner wall of the clamping plate 8, and the inner wall of the inner conical plate 9 fits against the outer wall of the outer conical barrel 6. The limiting assembly controls the expansion and contraction of the clamping plates 8 via a telescopic rod 7. When the outer conical barrel 6 is driven by the rotation of the threaded rod 4, its outer wall fits against the inner conical plate 9, allowing the clamping plate 8 to automatically unfold and clamp the film roll. This design not only stably fixes the film roll but also prevents the film roll from shifting or falling off during installation due to uneven tension or insecure clamping. The structural design of the clamping plate 8 allows it to accommodate film rolls of different sizes, improving the versatility of the device. The limiting component includes a telescopic rod 7, one end of which is fixedly connected to the outer wall of the main shaft 3, and the other end of which is fixedly connected to the inner wall of the clamping plate 8. The function of the telescopic rod 7 is to achieve precise clamping of the film roll by adjusting the tension of the clamping plate 8.
[0031] Specifically, when installing the film roll, first insert the film roll into the outer wall of the clamping plate 8 to ensure that the film roll is firmly fixed in the clamping plate 8. Next, rotate the threaded rod 4, and the rotation of the thread will drive the outer conical barrel 6 to move smoothly within the main shaft 3. The outer conical barrel 6 contacts the limiting groove 5 in the main shaft 3 through its outer wall, ensuring that the movement range of the outer conical barrel 6 within the main shaft 3 is precisely limited, thereby avoiding positional deviation. As the outer conical barrel 6 continues to move, its outer wall contacts the inner wall of the inner conical plate 9, and then the clamping plate 8 is unfolded outward by the force of the inner conical plate 9. The clamping plate 8 and the main shaft 3 are limited by the telescopic rod 7 to ensure that the clamping plate 8 will not shift excessively or loosen during the unfolding process, thereby achieving precise clamping and fixing of the film roll.
[0032] Reference Figure 3A frame 10 is mounted on one side of the base plate 1. A connecting shaft 11 is rotatably connected inside the frame 10. A support rod 12 is fixedly connected to one side of the connecting shaft 11, and the support rod 12 is fixedly connected to one side of the bracket 2. The base plate 1 provides the basic support for the entire device, ensuring that all components can be stably installed and work together. The frame 10, as a support structure, stably supports the main mechanical components of the device, and through the connection between the connecting shaft 11 and the support rod 12, it enables the rotation and movement of the device. The support rod 12 connects the frame 10 to the bracket 2, maintaining the stability and precise alignment of the device. A second connecting block 14 is fixedly connected to one side of the frame 10, and a first connecting block 13 is fixedly connected to one side of the connecting shaft 11. An electric push rod 15 is rotatably connected inside the second connecting block 14, and the output end of the electric push rod 15 is connected to the first connecting block 13. The first connecting block 13 and the second connecting block 14 achieve relative rotational movement through the connecting shaft 11, ensuring that the electric push rod 15 can accurately push the first connecting block 13. The electric actuator 15, as a drive component, provides stable thrust as needed, pushing the connecting block 13 through its output end, making the movement of the entire device more flexible and efficient. The design of the electric actuator 15 improves operational convenience, allowing for electric adjustment of the device's working position, avoiding the complexity of manual operation. The main shafts 3 are arranged in a linear array and fixedly connected to one side of the bracket 2. The design of the main shafts 3 ensures stable connection with the bracket 2, thereby achieving precise docking with other components.
[0033] Specifically, when the base plate 1 needs to be raised to accommodate operators of different heights, the electric push rod 15 extends its output end, causing the connecting block 13 to move smoothly, which in turn drives the connecting shaft 11 to rotate. The connecting shaft 11, through its connection with the support rod 12, converts the rotational motion into a vertical lifting force, thereby slowly and steadily raising the base plate 1. The bottom of the electric push rod 15 is tightly connected to the frame 10 via the connecting block 14, ensuring the stability and reliability of the entire structure. The base plate 1 can be precisely adjusted according to the operator's height requirements without manual intervention, making operation more convenient.
[0034] Working principle: When using this plastic film roll transfer device, the film roll is first inserted into the outer wall of the clamping plate 8. Then, the threaded rod 4 is rotated to drive the outer cone barrel 6 to move within the main shaft 3. The outer cone barrel 6 is limited within the main shaft 3 by the limiting groove 5. Then, the outer wall of the outer cone barrel 6 contacts the inner wall of the inner cone plate 9, and the clamping plate 8 is unfolded by the inner cone plate 9. The clamping plate 8 and the main shaft 3 are limited by the telescopic rod 7, which achieves the effect of facilitating the installation of the film roll.
[0035] When it is necessary to raise the base plate 1 to accommodate the height of the operator, the output end of the electric push rod 15 extends and drives the connecting shaft 11 to rotate through the connecting block 13. The connecting shaft 11 drives the base plate 1 to be raised through the support rod 12. The bottom of the electric push rod 15 is connected to the frame 10 through the connecting block 2 14, thus achieving the effect of accommodating operators of different heights.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
