Description

Technical Field

[0001] This utility model relates to the field of film processing equipment, and in particular to a pressure roller assembly for film winding. Background Technology

[0002] After the die-cutting process of the film is completed, the continuously output film needs to be rolled up to facilitate the delivery of the finished product. In the winding process, in order to ensure that the film remains tight as a whole and to avoid the film layers from becoming loose or wrinkled, the film is usually laminated and pressed during the winding process. Currently, the pressure rollers for film winding are mostly fixed in position, which can only be adapted to film rolls with a specific diameter range. As the diameter of the film roll gradually increases during the winding process, the pressure roller cannot adjust its fit with the film roll in sync, resulting in problems such as overpressure damage to the film and loosening, thus losing its auxiliary effect. Utility Model Content

[0003] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a pressure roller assembly for film winding, which solves the technical problem that the installation position of the pressure roller for film winding is mostly a fixed structure, which can only adapt to film rolls with a specific diameter range. When the diameter of the film roll gradually increases during the winding process, the pressure roller cannot adjust the fit with the film roll in sync, resulting in overpressure damage to the film and loosening and loss of auxiliary effect.

[0004] (II) Technical Solution The purpose of this utility model is to provide a pressure roller assembly for film winding, which includes a casing wall, a pressure roller mechanism, and a winding support shaft. The pressure roller mechanism and the winding support shaft are disposed on the side of the casing wall, and the winding support shaft is disposed below the pressure roller mechanism. The pressure roller mechanism includes a mounting base, a mounting shaft, a rotating support arm, and a downward rotating roller. The end of the mounting shaft is disposed in the mounting base, one end of the rotating support arm is movably disposed on the mounting shaft, and there are two rotating support arms. The other end of the rotating support arm is provided with the downward rotating roller, and the winding support shaft is located below the downward rotating roller.

[0005] Preferably, the mounting base is an integrally formed structure, which includes a fixed base plate and a mounting sleeve, wherein the mounting sleeve is horizontally disposed on the fixed base plate.

[0006] Preferably, the mounting sleeve has a blind hole inside, and the outer side of the mounting sleeve has a mounting screw hole, which passes through the side wall of the mounting sleeve and communicates with the blind hole.

[0007] Preferably, the mounting shaft is further provided with limiting rings, and the number of limiting rings is two or more, and the limiting rings are further provided with limiting screw holes that penetrate their bodies.

[0008] Preferably, the rotating support arm includes a connecting plate and a swing plate, one end of the swing plate is connected to the connecting plate, and the swing plate extends outward from one side of the connecting plate.

[0009] Preferably, one end of the connecting plate is provided with a connecting through hole, and the other end of the connecting plate is provided with a mounting countersunk hole.

[0010] Preferably, one end of the swing plate is provided with an internal threaded hole, the other end of the swing plate is provided with a limiting shaft hole, and the end of the swing plate is also provided with a fixing screw hole, which is connected to the limiting shaft hole.

[0011] Preferably, the downward rotating roller is a stationary shaft type downward roller.

[0012] (III) Beneficial Effects The downward rotating roller is connected to a rotating support arm mounted on a mounting shaft. Under the weight of the rotating support arm and the downward rotating roller, the wound film roll is kept in contact. Furthermore, by utilizing the cooperation between the rotating support arm and the mounting shaft, the downward rotating roller can automatically adjust as the diameter of the film roll changes, so that it always remains in contact with the surface of the film roll. Compared with the prior art, this application not only avoids the overpressure damage to the film and the loss of auxiliary effect due to the inability to adjust the contact with the film roll synchronously, but also improves the stability of the film winding process to a certain extent.
