Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production equipment of rewinders, in particular to a rewinder device for isolation films of different materials, which is applied to the recycling of isolation films of PVB glass interlayer films. Background Art
[0002] The storage of PVB glass interlayer film requires that the finished films be isolated and stored. The scrapped finished rolls need to be crushed and recycled. Therefore, when crushing, the isolation film in the middle needs to be separated and rolled up for recycling. This requires a set of isolation film rewinding devices. Isolation films of different specifications and thicknesses can withstand different tensions. By adjusting the counterweight, it can be applied to the winding of isolation films of various materials, and can maintain the winding line speed and stable tension fluctuations to prevent the film from being broken and causing production line shutdown. Utility Model Content
[0003] The purpose of the utility model is to develop a rewinding device for isolation films of different materials, to solve the problem of stable winding line speed during the isolation film winding process, to ensure that the isolation film is not broken, and to affect the production continuity of the production line.
[0004] The technical solutions adopted by the present invention to achieve the above-mentioned purpose are as follows:
[0005] A rewinding device for release films of different materials, comprising a frame 1, a drive motor 2, a transmission assembly 3, an air expansion shaft 4, a swing guide roller 5, a counterweight 6, a rotating shaft 7, a gear transmission mechanism 8, an angle displacement sensor 9, and a safety chuck 10;
[0006] The vertical components are fixed at both ends of the frame 1; the two ends of the pneumatic shaft 4 are located on the vertical component through the safety chuck 10; the transmission component 3 is connected to the drive motor 2 and the safety chuck 10; the two ends of the rotating shaft 7 are respectively fixed to the two ends of the frame 1 through the seat bearings; the counterweight block 6, the end of the rotating shaft 7, and the end of the swing guide roller 5 are connected in sequence through the connecting plate; one end of the rotating shaft 7 is connected to the gear transmission mechanism 8 through a key; the gear transmission mechanism 8 is connected to the angle displacement sensor 9; the angle displacement sensor 9 is fed back to the drive motor 2 through signal transmission.
[0007] The transmission assembly 3 includes a synchronous toothed belt, a synchronous pulley, and a tapered lock sleeve; the synchronous pulley is connected to the drive motor 2; the synchronous pulley is connected to the safety chuck 10 through the tapered lock sleeve; the synchronous toothed belt is wound around the synchronous pulley in a circle.
[0008] The center distance between the counterweight block 6 and the rotating shaft 7 varies according to the maximum tension that the material film can withstand.
[0009] The swing guide roller 5 includes a roller, a bearing and a shaft; the roller is sleeved on the shaft through the bearing, and both ends of the shaft are connected to the connecting plate.
[0010] The beneficial effects of the utility model include: convenient connection and maintenance of the transmission assembly, and synchronous transmission of the pneumatic shaft and the drive motor is achieved when the device is running.
[0011] The swinging guide roller ensures flexible rotation of the roller and prevents a linear speed difference with the isolation film. A swinging guide roller is mounted on one side of the shaft, and a counterweight is mounted on the other. In the absence of film tension, the guide roller is in a horizontal position, held in place by a limiter. As the roll diameter increases, the film tension increases, pulling the swinging guide roller upwards. Simultaneously, the shaft drives the gear transmission mechanism, which in turn drives the angular displacement sensor connected to the gear for detection. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of a rewinding device for release films of different materials according to the present invention.
[0013] Among them: 1-frame, 2-drive motor, 3-transmission assembly, 4-air expansion shaft, 5-swing guide roller, 6-counterweight, 7-rotating shaft, 8-gear transmission mechanism, 9-angle displacement sensor, 10-safety chuck. DETAILED DESCRIPTION
[0014] like Figure 1 As shown, the rewinder device for release films made of different materials includes: a frame 1, a drive motor 2, a transmission assembly 3, an air shaft 4, an oscillating guide roller 5, a counterweight 6, a rotating shaft 7, a gear transmission mechanism 8, an angular displacement sensor 9, and a safety chuck 10. The frame 1 is fixed to the ground via expansion bolts; the safety chuck 10 is connected to the frame 1 via a base; both ends of the air shaft 4 are clamped onto the safety chuck 10; the drive motor 3 is fixed to the frame 1 via a connecting seat; the drive motor 3 drives the safety chuck 10 to rotate via the transmission assembly 4, which in turn drives the air shaft 5 to rotate; the oscillating guide roller 5 and the counterweight 6 are mounted on either side of the rotating shaft 7, one end of which is connected to the gear transmission mechanism 8 via a key; the gear transmission mechanism 8 is connected to the angular displacement sensor 9.
[0015] Preferably, the transmission assembly 3 is composed of a synchronous toothed belt, a synchronous pulley, and a tapered lock sleeve, which is easy to connect and realizes synchronous transmission of the pneumatic shaft and the motor.
[0016] Preferably, the swing guide roller 5 is composed of a roller, a bearing, and a shaft to ensure that the roller rotates flexibly and does not produce a linear speed difference with the isolation membrane.
[0017] Preferably, a swinging guide roller 5 is installed on one side of the rotating shaft 7, and a counterweight block 6 is installed on the other side. In the absence of film tension, it is in a horizontal position through a limiter. When the roll diameter becomes larger, the tension of the film becomes larger, which will pull up the swinging guide roller 5. At the same time, the rotating shaft 7 drives the gear transmission mechanism, and then the angle displacement sensor connected to the gear detects the angle change to adjust the driving motor speed.
[0018] The use process of the rewinding device for the isolation films of different materials is as follows:
[0019] A paper core is put on the air-expanding shaft 4 and installed on the safety chuck 10 . The separated isolation film passes over the lower end of the swing guide roller 5 and is wound around the paper core of the air-expanding shaft 4 .
[0020] Start the drive motor 2, as Figure 1 The film shown begins to curl on the air inflation shaft 4. As the roll diameter increases, the tension of the film increases, pulling up the swinging guide roller 5. The rotation of the swinging guide roller 5 will drive the rotation of the rotating shaft 7, and the gear transmission mechanism 8 will synchronously rotate the corresponding degree. The angle displacement sensor 9 detects the angle change and feeds back to the drive motor 2. The drive motor 2 changes speed accordingly to keep the tension of the film at the original setting.
[0021] In addition, the above description is only explained according to the implementation method, not all implementation plans. Based on the implementation plan of the present utility model, technical personnel in this field should understand that any modifications or equivalent replacements that do not depart from the purpose and scope of this implementation plan are covered within the scope of protection of the present utility model.
