Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of transfer equipment, and more specifically, to a transfer device for ultra-heavy film rolls. Background Technology
[0002] The production of medical infusion membrane materials has developed significantly in recent years. Large-size multi-chamber bag membrane materials are increasingly widely used in food packaging, pharmaceuticals, chemicals, industry, agriculture and other fields due to their unique and excellent properties.
[0003] In existing technologies, large-size multi-compartment infusion bags are generally prepared using multi-layer co-extrusion composite blown film technology. The specific method involves placing the raw materials for each layer of the film material into the corresponding extruder hopper of a co-extrusion blown film machine, extruding them through a high-temperature die, and then water-cooling or air-cooling. The resulting film bubble is then shaped by a herringbone plate, pulled by traction rollers, and wound up. Unlike general plastic products, powder-liquid multi-compartment infusion bags are typically sterilized under humid heat conditions with high temperature, humidity, and pressure before being filled with medication.
[0004] In actual blown film production, due to the large diameter, length, and weight of large-format film materials, there are certain safety uncertainties during the inner and outer packaging transfer process. During transfer, there is a risk of film rolls falling and causing injuries, and operators twisting their arms or backs while handling the film rolls onto pallets. Therefore, it is necessary to design a device that can assist in transferring film rolls. Utility Model Content

Detailed Implementation
[0020] Example
[0021] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 5As shown, the transfer device for the heavy film roll in this embodiment includes a base 10, a column 11 vertically mounted on the base 10, a first support arm 12 horizontally mounted and hinged to the column 11, a second support arm 13 horizontally mounted and hinged to the first support arm 12, and a clamping device 20 located below the second support arm 13. The clamping device 20 includes a slide rail 21 horizontally mounted below the second support arm 13, a pair of clamping members 22 slidably mounted at both ends of the slide rail 21, and a first driving device 23 for driving the pair of clamping members 22 to move along the slide rail 21. The clamping member 22 includes a first slider 221 slidably connected to the slide rail 21, a sliding plate 222 vertically mounted below the first slider 221, and a pair of clamping plates 226 located at the upper and lower ends of the sliding plate 222. The pair of sliding plates 222 are parallel to each other, and the film roll 40 is clamped between the clamping plates 226. Specifically, in use, the first driving device 23 drives a pair of clamping members 22 to move away from each other, moving the clamping plate 226 to the side of the roll film 40. Then, the first driving device 23 drives the pair of clamping members 22 to move closer together, so that the clamping plate 226 clamps the side wall of the roll film 40. Then, the roll film 40 can be pushed for small-range transfer. It is applicable to roll films 40 of different diameters and lengths. It can significantly reduce the labor intensity of workers. This device is mainly used for transferring large-volume roll films 40, so it does not need to be fixed to the ground or a special hydraulic system is required. Therefore, it occupies less space and can be better transferred and stored.
[0022] In this embodiment, the first driving device 23 includes a pair of driving blocks, threaded holes on the driving blocks, a first screw 231 threadedly connected to the threaded holes on the driving blocks, a support plate 232 fixedly connected to the slide rail 21, and a first motor 233 mounted on the support plate 232. The pair of driving blocks are respectively fixedly connected to a pair of sliding plates 222. The thread directions of the threaded holes on the pair of driving blocks are opposite. The output shaft of the first motor 233 is connected to the first screw 231, and the first screw 231 passes through the pair of sliding plates 222. Specifically, the first motor 233 drives the first screw 231 to rotate, thereby driving the pair of driving blocks to move in opposite directions along the screw. The driving blocks can move the pair of sliding plates 222 and the clamping plate 226, thereby realizing the clamping and releasing of the roll film 40.
[0023] The clamping device 20 in this embodiment also includes a first rotating shaft 223 horizontally and rotatably disposed at the lower end of the slide plate 222, a rotating plate 224 fixedly connected to the first rotating shaft 223, and a second driving device 24 for driving one of the rotating plates 224 to rotate; a pair of clamping plates 226 are respectively disposed at both ends of the rotating plate 224; the plane of the rotating plate 224 is parallel to the plane of the slide plate 222. Specifically, the first driving device 23 can drive the rotating plate 224 to rotate. When the roll film 40 is clamped by the rotating plate 224 and the clamping plates 226, by driving one of the rotating plates 224 to rotate, the roll film 40 can be driven to flip, while the other rotating plate 224 will rotate under the drive of the roll film 40, which makes it easier to perform operations such as flipping the roll film 40.
[0024] In this embodiment, both ends of the rotating plate 224 are slidably equipped with slide tubes 225, and a clamping plate 226 is hinged to a slide tube 225 via a second rotating shaft 227; the second rotating shaft 227 is horizontally set and perpendicular to the axial direction of the first rotating shaft 223. Specifically, the gap between a pair of clamping plates 226 can be adjusted by moving the slide tube 225, thereby enabling adjustment for rolls of film 40 with different diameters (the slide tube 225 needs to be fixed with bolts after adjustment). Similarly, the angle between the clamping plate 226 and the slide tube 225 can be adjusted according to the diameter of the roll of film 40.
[0025] In this embodiment, the second driving device 24 includes a second motor 241 disposed on the side wall of one of the slide plates 222, and the output shaft of the second motor 241 is connected to one of the first rotating shafts 223. Specifically, by fixing the second motor 241 on the slide plate 222 and connecting it to the adjacent first rotating shaft 223, the second motor 241 can drive the first rotating shaft 223 to rotate, thereby flipping the roll film 40.
[0026] In this embodiment, the column 11 has a hollow internal structure, and a sliding hole 31 is provided on the side of the column 11. A second screw 32 is rotatably installed inside the column 11, and the second screw 32 is connected to a third motor 33. A second slider 34 is threadedly connected to the outer wall of the second screw 32. The first support arm 12 passes through the sliding hole 31 and is fixedly connected to the second slider 34. Specifically, the third motor 33 drives the second screw 32 to rotate, which in turn drives the second slider 34, the first support arm 12, the second support arm 13, the clamping device 20, and the film roll 40 to move vertically, thereby achieving the purpose of adjusting the height of the film roll 40.
[0027] In this embodiment, a sleeve 14 is fixedly provided at the lower end of the column 11, and a limiting tube 15 is provided at the base 10; the sleeve 14 is rotatably disposed in the limiting tube 15; a fourth motor 16 is fixedly provided inside the base 10, and a driving gear 17 is provided on the output shaft of the fourth motor 16; a driven gear 18 is fixedly provided at the lower end of the column 11, and the driving gear 17 meshes with the driven gear 18; the fourth motor 16 is disposed inside the sleeve 14. Specifically, the fourth motor 16 can drive the column 11 to rotate, so that after the clamping device 20 clamps the roll film 40, it can move in various directions and angles.
[0028] In summary, the heavy-duty film roll transfer device of this embodiment uses a first drive device 23 to drive a pair of clamping members 22 away from each other, moving the clamping plate 226 to the side of the film roll 40. Then, the first drive device 23 drives the pair of clamping members 22 closer together, so that the clamping plate 226 clamps the side wall of the film roll 40, allowing the film roll 40 to be moved within a small range. This device is applicable to film rolls 40 of different diameters and lengths. It can significantly reduce the labor intensity of workers. Furthermore, this device is mainly used for transferring large-volume film rolls 40, so it does not need to be fixed to the ground or require a dedicated hydraulic system, thus occupying less space and enabling better transfer and storage.
