Description

Technical Field

[0001] This utility model relates to the field of film processing equipment, and in particular to a dual-station film winding machine. Background Technology

[0002] PI (polyimide) film is a high-performance thin-film insulating material with excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and dielectric resistance. PI film is widely used in aerospace, electrical / electronic, microelectronics, nanotechnology, liquid crystal, separation membranes, lasers, locomotives, automobiles, precision machinery, and automated office machinery.

[0003] Winding machines are used in the casting production process of PI film to wind the film. Winding machines include single-station and double-station models. A single-station winding machine has only one winding roller, requiring a stop for roll changing, resulting in low automation, low efficiency, and negatively impacting production quality. A double-station winding machine has two winding rollers; while one roller is winding, the other can simultaneously take up and change rolls, improving production efficiency.

[0004] Patent application CN202311698962.4 discloses a dual-station automatic edge material winding machine. The frame is sequentially arranged with a first transition roller, a reciprocating guide mechanism, a second transition roller, and a dual-station winding mechanism along the edge material conveying direction. A film-cutting mechanism is also installed on the frame. When one winding shaft of the dual-station winding mechanism is winding, the reciprocating guide mechanism guides the edge material to be evenly wound around the paper core of that winding shaft. When the dual-station winding mechanism switches to the other winding shaft, the film-cutting mechanism cuts the edge material spanning between the two winding shafts, and the reciprocating guide mechanism continues to guide the edge material to be evenly wound around the paper core of the other winding shaft, enabling continuous winding without stopping the machine. However, this dual-station winding machine requires a reciprocating guide mechanism to guide the edge material onto the winding shaft during winding, resulting in a relatively complex overall structure. Furthermore, the tension of the edge material is prone to fluctuation during winding, affecting the winding quality. Utility Model Content

[0005] In response to the aforementioned shortcomings of existing dual-station film winding machines, the applicant provides a structurally sound dual-station film winding machine with a simple structure. During the winding process, the tension of the film is adjusted in real time to ensure the quality of winding.

[0006] The technical solution adopted in this utility model is as follows:

[0008] The tension adjusting roller assembly includes an adjusting shaft and a swing roller. The two ends of the swing roller are connected to the adjusting shaft via swing arms, and the swing arms are connected to the adjusting cylinder.

[0009] The pressure roller of the pressing assembly is mounted on the roller seat, which is connected to the pressing cylinder. The pressing cylinder can drive the pressure roller to extend or retract towards the dual-station winding mechanism through the roller seat.

[0010] The dual-station winding mechanism is equipped with a station switching shaft, which is connected to a shaft drive device.

After the film enters the tension adjustment roller group, it passes around the adjustment roller-swing roller-adjustment roller in sequence.

[0014] The roller seat of the pressing assembly is movably slidably mounted on the guide rail, which is horizontally fixed on the frame. The pressing cylinder can drive the roller seat and the pressure roller to move horizontally along the guide rail.

[0015] The two winding stations of the dual-station winding mechanism have their winding rollers mounted on a turntable assembly, which is vertically mounted on a station switching shaft. The winding rollers of the two winding stations are symmetrically arranged on opposite sides of the station switching shaft.

[0016] Each take-up roller is connected to the turntable assembly at both ends via a quick-release mechanism; the shaft drive is located on the outside of the turntable assembly at one end; the take-up drive is located on the outside of the turntable assembly at the other end.

[0017] The dual-station winding mechanism's shaft drive is equipped with a parking brake function.

[0018] Each winding station of the dual-station winding mechanism is equipped with a winding roller, an electrostatic eliminator, and a diameter measuring instrument.

[0019] The cutting assembly is equipped with a cutting shaft, a tension roller, and a swing cylinder. The cutting shaft is equipped with a swing rod, which is connected to the swing cylinder. The cutting cutter and the tension roller are connected to the swing rod.

[0020] The tensioning roller includes a first tensioning roller and a second tensioning roller. The cutting tool is positioned between the first tensioning roller and the second tensioning roller. Both ends of the cutting tool are connected to the first tensioning roller via vertical rods. Both ends of the first tensioning roller are connected to cutting cylinders, which are connected to swing rods.

[0021] The swing arm includes an outer swing arm and an inner swing arm. One end of the outer swing arm is connected to the cutting shaft, and the other end is connected to the swing cylinder. One end of the inner swing arm is connected to the cutting shaft, and the other end is connected to the cutting tool, the first tension roller, and the second tension roller.

[0022] The beneficial effects of this utility model are as follows:

[0023] The dual-station winding machine provided by this utility model has a simple overall structure and is easy to operate. During the winding process, the winding tension of the film is monitored and adjusted in real time through the tension detection roller and the tension adjustment roller group, and the tension fluctuation of the film is fed back in real time. The tension adjustment system adjusts the tension according to the tension fluctuation to ensure the consistency of the winding tension and the quality of winding. Attached Figure Description

On the frame 1, a cutting assembly 7 is arranged corresponding to the dual-station winding mechanism 6.

[0041] like Figure 1 As shown, the tension detection roller 2 is set on the material receiving side of the tension regulating roller group 3. The tension detection roller 2 and the tension regulating roller group 3 monitor and regulate the winding tension of the film 100 in real time, and provide real-time feedback on the tension fluctuation of the film 100.

[0042] like Figures 1 to 3 As shown, the tension adjusting roller assembly 3 includes an adjusting shaft 31 and a swing roller 32. The adjusting shaft 31 is fixed at both ends to the frame 1. The swing roller 32 is connected at both ends to the adjusting shaft 31 via swing arms 33. The swing arms 33 are connected to an adjusting cylinder 34, which is also connected to the frame 1.

Both ends of each winding roller shaft 64 are connected to the turntable assembly 63 via a quick-release structure 641, and one end of each winding roller shaft 64 is connected to the winding drive device 65 via a transmission structure. The shaft drive device 62 is located on the outside of one turntable assembly 63, and the winding drive device 65 is located on the outside of the other turntable assembly 63. The shaft drive device 62 is equipped with a parking brake function, which brakes the station switching shaft 61 after the dual-station winding mechanism 6 rotates to the designated station. On the turntable assembly 63, a winding guide roller 67, an electrostatic eliminator 68, and a diameter gauge 69 are respectively provided for each winding station. The winding guide roller 67 is used to guide the film 100 to the winding roller shaft 64, the electrostatic eliminator 68 is used to eliminate static electricity, and the diameter gauge 69 is used to detect the outer diameter of the fully rolled film.
