Description

Technical Field

[0001] This utility model relates to the field of stretch film winding technology, specifically a stretch film pressing device. Background Technology

[0002] Stretch film, also known as heat shrink film, was initially produced in China using PVC as the base material and DOA as a plasticizer for self-adhesion. However, due to environmental concerns, high cost (relatively higher density than PE, resulting in smaller packaging area per unit area), and poor tensile strength, it was gradually phased out when PE stretch film production began in China in 1994-1995. PE stretch film initially used EVA as the self-adhesive material, but its high cost and odor led to the development of PIB and VLDPE as self-adhesive materials. The base material is primarily LLDPE, including C4, C6, C8, and metallocene PE (MPE).

[0003] Chinese Patent CN221396315U discloses a film pressing device for stretch film, which includes a worktable with a back support frame fixed to one end of the top of the worktable. The upper part of the worktable is also provided with a sliding groove. The pressing mechanism includes an n-shaped hanger horizontally arranged below the straight section of the upper part of the back support frame. In use, when the roller winds the fed stretch film, ultrasonic rangefinders located on both sides of the film body will detect the spacing of the stretch film near the positioning plate in real time. The control end can determine the range of the stretch film's deviation to one side based on the average value of the spacing values ​​on both sides. This can effectively reduce the drawbacks of misalignment and poor winding quality of the stretch film during winding, thus meeting the usage requirements of the film pressing device.

[0004] The aforementioned related technologies have certain shortcomings. In practical applications, the stretch film is usually wound onto a core, which facilitates subsequent transportation and use. However, this device directly winds the stretch film onto the roller, making the unloading process inconvenient and causing many adverse effects on subsequent operations. Therefore, it is necessary to provide a stretch film pressing device to solve the above-mentioned technical problems. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model utilizes a processing table, support legs, a fixed plate, a first servo motor, a winding frame, a positioning cylinder, a movable plate, a limit rod, a support plate, an electric telescopic rod, a track, an adjusting screw, a second servo motor, and an adjusting block. In use, the movable plate is pushed by the electric telescopic rod to clamp and fix the core between the two winding frames.

After winding, the electric telescopic rod is used again to increase the distance between the winding frames to release the limit. Then, the second servo motor is started, and the adjusting block moves the movable plate through the screw drive and track, removing the winding frame and positioning cylinder. This allows for unobstructed and rapid unloading by workers, greatly improving ease of use.

[0020] 2. This utility model utilizes the combined use of a groove, a pressing roller, a guide roller, a movable frame, a fixed frame, an automatic telescopic rod, a fixed block, a slider, a connecting rod, a threaded rod, and a third servo motor. During operation, the stretch film passes between the pressing roller and the guide roller, and the third servo motor is activated to drive the threaded rod to rotate. The left-hand and right-hand threaded transmission on the threaded rod, combined with the slider's sliding guidance within the groove, enables relative or opposite movement of the slider. This relative movement of the slider changes the angle of the connecting rod, raising the movable frame and causing the pressing roller to move closer to the guide roller, applying pressure to the stretch film. This prevents the film from becoming loose or wrinkled, effectively improving the winding quality of the stretch film and ensuring a tight and orderly winding. Attached Figure Description

[0043] The working principle of this utility model is as follows: All electrical components mentioned in this article are electrically connected to an external main controller and 220V AC mains power. The main controller can be a computer or other conventionally known control device. Parts not mentioned in this device are the same as or can be implemented using existing technology. During use, one end of the core is fitted onto the positioning cylinder 6 on the winding frame 5 on the side of the fixed plate 3. Then, the electric telescopic rod 10 is activated, and its drive end pushes the movable plate 7 to move laterally. The movable plate 7 drives the winding frame 5 and the positioning cylinder 6 on its side to move synchronously until the positioning cylinder 6 on the side of the movable plate 7 engages with the other end of the core, achieving clamping and fixing of the core between the two winding frames 5. Next, the drive end of the first servo motor 4 is controlled to drive the winding frame 5 to rotate, thereby causing the core to rotate and completing the winding operation of the wrapping film. After the wrapping film is wound, the distance between the two winding frames 5 is increased by the drive end of the electric telescopic rod 10, releasing the left winding frame 5 and the positioning cylinder 6 from limiting the core. Then, the second servo motor 13 is started, and its drive end drives the adjusting screw 12 to rotate. Utilizing the threaded transmission between the adjusting screw 12 and the adjusting block 19, as well as the sliding cooperation between the adjusting block 19 and the track 11, the adjusting block 19 moves smoothly longitudinally. The adjusting block 19 drives the support plate 9 to move, and the support plate 9 drives the movable plate 7 to move through the electric telescopic rod 10, thereby removing the winding frame 5 and the positioning cylinder 6 on the side of the movable plate 7 from one end of the core. At this time, the operator can quickly and unload the core and the film wrapped on it without any obstruction, which effectively improves the convenience of use.

[0044] During the wrapping film winding operation, the wrapping film is passed between the extrusion roller 15 and the guide roller 16. Then, the third servo motor 26 is activated, and its drive end rotates the threaded rod 24. Utilizing the thread transmission characteristics of the left-hand and right-hand threads on the threaded rod 24, combined with the sliding guidance of the slider 22 within the groove 14, relative or opposite movement of the two sliders 22 is achieved. When the two sliders 22 move relative to each other, the included angle between the two connecting rods 23 changes, thereby raising the movable frame 17. The displacement of the movable frame 17 causes the extrusion roller 15 to move, bringing it closer to the guide roller 16, thus applying a pressing force to the wrapping film and effectively improving the winding quality.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
