After the film passes through the dust absorption roller 23, it continues to be transmitted forward and passes through the top side of the tension guide roller 5, because the distance from the central axis of the tension guide roller 5 to the central axis of the rotating shaft 3 is not the same, the limit block 10 is pulled, so that the return spring 11 is stretched, the limit rod 9 is separated from the limit hole 7, then the rotating handle 6 can drive the rotating shaft 3 to rotate, so that the mounting bracket 4 and the tension guide roller 5 of different heights are adjusted to the appropriate position, then under the action of the return spring 11, the limit rod 9 is inserted into the appropriate limit hole 7 again, that is, when the film passes through the tension guide roller 5, the contact angle and the wrap angle of the film with the tension guide roller 5 change at different positions, so that the tension of the film in the transmission process is changed. If the film passes through the tension guide roller 5 far from the central axis of the rotating shaft 3, the tension of the film will increase accordingly;Conversely, the tension decreases when passing through the closer tension guide roller 5, so that the tension of the film during winding is accurately adjusted, and the film winding effect is guaranteed.

[0024] Please refer to Figure 1 、 2 , 4, 5, the top side of the workbench 1 is equipped with fixed plate 12, the inside of the fixed plate 12 is rotatably installed with unwinding roller 13.

[0025] The top side of the workbench 1 is equipped with vertical plate 14, one side of the vertical plate 14 is equipped with winding motor 15, the output end of the winding motor 15 is equipped with winding shaft 16, the winding shaft 16 is movably assembled with winding drum 17, one end of the winding shaft 16 is equipped with threaded rod 18, the outer side of the threaded rod 18 is threadedly connected with nut 19.

[0026] The top side of the workbench 1 is provided with a mounting plate 20, the inside of the mounting plate 20 is provided with a U-shaped pipe 21, a plurality of through holes 22 are equidistantly formed in the inside of the U-shaped pipe 21, dust suction rollers 23 are rotatably installed at the outer sides of the two ends of the U-shaped pipe 21, dust suction holes 24 are formed in the dust suction rollers 23, a dust collecting box 25 is installed on one side of the workbench 1, a conveying pipe 26 is connected to the top side of the dust collecting box 25, one end of the conveying pipe 26 is in communication with the U-shaped pipe 21, a negative pressure motor 27 is installed on the bottom side inner wall of the dust collecting box 25, three fan blades 28 are installed on the output end of the negative pressure motor 27, a filter plate 29 is installed on the inner wall of the dust collecting box 25, and an exhaust pipe 30 is installed at the bottom end of the dust collecting box 25.

[0027] In the working process, the PET composite film is wound on the unwinding roller 13, passes between the two dust suction rollers 23, passes through the top side of the tension guide roller 5, and finally starts to be wound on the winding drum 17. One side of the workbench 1 is provided with a control panel 31. In the working process, the preservative film is wound into a roll by the winding device, which is convenient for packaging and sales. Therefore, a winding device is needed. First, the PET composite film roll is installed on the unwinding roller 13. The film is output from the top side of the unwinding roller 13. When the film passes between the two dust suction rollers 23, the negative pressure motor 27 is started. The negative pressure motor 27 drives the fan blades 28 to rotate at high speed, generating a negative pressure environment in the dust collecting box 25. The external air enters the dust suction roller 23 through the dust suction hole 24 under the action of negative pressure, and then enters the U-shaped pipe 21 through the through hole 22, and then flows into the dust collecting box 25 through the conveying pipe 26. In this process, the dust and impurities on both sides of the film are adsorbed on the surface of the dust suction roller 23 and are carried into the dust collecting box 25 along with the air flow. After being filtered by the filter plate 29, the clean air is discharged from the exhaust pipe 30, realizing effective cleaning of both sides of the film and ensuring the cleanliness of the wound film. After the film is tensioned, it finally reaches the winding drum 17. The winding motor 15 is started, the winding shaft 16 is driven to rotate by the winding motor 15, the winding drum 17 is driven to rotate by the winding shaft 16, so that the film starts to be wound on the winding drum 17. After winding is completed, the nuts 19 can be loosened, the nuts 19 are unscrewed from the threaded rods 18, the winding drum 17 is conveniently removed, the winding drum 17 is quickly replaced, and the next winding work is carried out.

[0028] Working principle: first, the PET composite film roll is installed on the unwinding roller 13, the film is output from the top side of the unwinding roller 13, when the film passes between the two dust absorption rollers 23, the negative pressure motor 27 is started, the negative pressure motor 27 drives the fan blade 28 to rotate at high speed, a negative pressure environment is generated in the dust collection box 25, the external air enters the dust absorption roller 23 through the dust absorption hole 24 under the action of negative pressure, and then enters the U-shaped pipe 21 along the through hole 22, and then flows into the dust collection box 25 through the conveying pipe 26. In this process, the dust and impurities on both sides of the film are adsorbed to the surface of the dust absorption roller 23, and are brought into the dust collection box 25 along with the air flow. After being filtered by the filter plate 29, the clean air is discharged from the exhaust pipe 30, realizing effective cleaning of both sides of the film and ensuring the cleanliness of the winding film.

[0029] After the film passes through the dust absorption roller 23, it continues to transmit forward and passes from the top side of the tension guide roller 5. Since the distance from the central axis of the tension guide roller 5 to the central axis of the rotating shaft 3 is not the same, the limit block 10 is pulled, so that the return spring 11 is stretched, the limit rod 9 is separated from the limit hole 7, and then the rotating handle 6 can drive the rotating shaft 3 to rotate, thereby adjusting the mounting frame 4 and the tension guide roller 5 of different heights to the appropriate position. Then, under the action of the return spring 11, the limit rod 9 is inserted into the appropriate limit hole 7 again, that is, when the film passes around the tension guide roller 5, the contact angle and wrap angle of the film at different positions with the tension guide roller 5 change, thereby changing the tension of the film in the transmission process. If the film passes around the tension guide roller 5 far from the central axis of the rotating shaft 3, the tension of the film will increase accordingly; on the contrary, if the film passes around the tension guide roller 5 close to the central axis of the rotating shaft 3, the tension will decrease, realizing accurate adjustment of the tension of the film during winding and ensuring the effect of film winding.

[0030] After the tension adjustment, the film finally reaches the winding drum 17, the winding motor 15 is started, the winding motor 15 drives the winding shaft 16 to rotate, the winding shaft 16 drives the winding drum 17 to rotate, so that the film starts to wind on the winding drum 17. After winding is completed, the nut 19 can be loosened, the nut 19 is rotated off the threaded rod 18, the winding drum 17 is conveniently taken off, the winding drum 17 is quickly replaced, and the next round of winding work is realized.
