Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a roller adjustment device for plastic film processing. Background Technology

[0002] Plastic film refers to thin films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products are gaining an increasingly larger market share, especially composite plastic flexible packaging, which is widely used in the food, pharmaceutical, and chemical industries. Food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, and fast food packaging. These products have brought great convenience to people's lives.

[0003] A roller adjustment device for plastic film processing, disclosed in patent number CN216376796U, includes a base. An adjustment mechanism and a support frame are mounted on the top of the base. A top plate is connected to the top of the adjustment mechanism. A roller component is sleeved on the inner side of the top of the support frame. Transition conveying mechanisms are movably sleeved on the inner sides of both ends of the roller component. One transition conveying mechanism on one side of the roller component is connected to a pumping component, while the other transition conveying mechanism on the other side is connected to a return pipe. One end of the return pipe and the bottom of the pumping component are connected to a coolant tank, which is installed on the top surface of the support frame. The two sets of transition conveying mechanisms, pumping components, return pipes, and coolant tanks in this invention cooperate to form a liquid circulation mechanism. When used in conjunction with the roller component, this mechanism can circulate and cool the roller component without interfering with its plastic film processing operations.

[0004] However, the above-mentioned device still has the following problems during implementation:

[0005] 1. However, existing plastic film processing winding devices have the problem of inconvenience in removing the wound plastic film, and cannot be adapted to the needs of plastic film production during the winding process, nor can they limit and protect the plastic film, and the winding is prone to deviation.

[0006] 2. Existing plastic films require conveying via rollers during processing. These rollers need to be adjusted to ensure stable conveying. However, the existing roller structure is relatively simple. Currently, plastic films cannot provide auxiliary protection for the material being wound up, and the ends of the winding shaft are subjected to significant stress, which can easily cause damage.

[0014] Preferably, the base support assembly includes a base bracket, a movable bracket, and an auxiliary shaft. The base bracket is fixedly installed on the upper surface of the support plate. The movable brackets are symmetrically installed inside the base bracket. The two sets of movable brackets corresponding to the base bracket are connected and installed through the auxiliary shaft. The movable brackets installed in the base bracket are elastically connected at intervals by tension springs.

[0015] Preferably, both sets of hollow blocks have hollow grooves inside, and buffer springs are symmetrically arranged and fixedly installed inside each hollow groove.

[0017] Preferably, two sets of adjusting blocks are symmetrically arranged, and threaded holes are symmetrically opened on the positioning plates of both sets. One end of the adjusting screw passes through and is threaded into the inside of the threaded hole. The adjusting screw facilitates the adjustment of the two sets of relatively arranged adjusting blocks to move closer or further apart, and is adjusted to match the width of the plastic film to be wound up as needed.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] 1. The plastic film is wound up by a set take-up shaft, which is movably connected to the upper surface of the bracket. After winding is completed, it is easy to pick up the material.

[0031] One of the upright plates 2 has a motor support plate 10 fixedly installed on one side, and a drive motor 11 is fixedly installed on the upper surface of the motor support plate 10. The output end of the drive motor 11 is matched with one end of the winding shaft 3.

[0032] The output end of the drive motor 11 is keyed to a connecting sleeve 12. A locking bolt 13 is bolted through the outside of the connecting sleeve 12. One end of the take-up shaft 3 is inserted into the connecting sleeve 12 and is pressed against the outer surface of the take-up shaft 3 by the end of the locking bolt 13. Two sets of limiting plates 14 are symmetrically and fixedly installed on both sides of the outer surface of the take-up shaft 3. The upper surface of the bracket 301 is provided with an arc-shaped notch 15. The take-up shaft 3 is matched with the arc-shaped notch 15.

[0033] The base support assembly 5 includes a base support frame 501, a movable bracket 502, and an auxiliary shaft 503. The base support frame 501 is fixedly installed on the upper surface of the tray 4. The movable brackets 502 are symmetrically installed inside the base support frame 501. The movable brackets 502 of the two sets of base support frames 501 are connected and installed through the auxiliary shaft 503. The movable brackets 502 installed in the base support frame 501 are elastically connected at intervals by tension springs 16. The plastic film is wound up by the winding shaft 3.

The adjusting screw 902 can be used to adjust the two sets of relatively arranged adjusting blocks 901 to move closer or further apart, and to match the width of the plastic film to be wound up as needed.

[0038] Working principle: The plastic film is wound up by the winding shaft 3, which is movably connected to the upper surface of the bracket 301. After winding is completed, it is easy to pick up the material. The bottom support assembly 5 supports the plastic film wound on the outer surface of the winding shaft 3, which increases the stability of the plastic film winding. When the thickness of the plastic film wound on the outer surface of the winding shaft 3 increases, the tension spring 16 of the bottom support assembly 5 can elastically close the auxiliary shaft to match and support the plastic film.

[0039] The plastic film is limited by the setting limit roller 8, so that the plastic film can be flattened before winding. The two sets of symmetrically set adjustment blocks 901 facilitate matching adjustment for plastic films of different widths. The two sets of adjustment blocks 901 are adjusted to move closer or further apart by adjusting screw 902.
