[0021] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a degradable winding film tension adjusting device, including bottom plate 1, limit roller 2, air cylinder 3, driving plate 4, wing rod 5, pull rope 6, passive plate 7, gyro wheel 8, support rod 9, collar 10, lifting rod 11, lifting frame 12, plate sleeve 13, pressure sensor 14 and adjusting roller 15, the upper surface both ends of bottom plate 1 are respectively installed with limit roller 2, and the middle of bottom plate 1 upper surface is provided with air cylinder 3, and the tail end of air cylinder 3 output shaft is fixedly connected with driving plate 4, and the side outer wall of driving plate 4 is fixedly provided with wing rod 5, while the outer wall of wing rod 5 is connected with passive plate 7 by pull rope 6, the lower surface of driving plate 4 and passive plate 7 is all installed with gyro wheel 8, and the upper surface of driving plate 4 and passive plate 7 is all provided with lifting rod 11, and the upper end of lifting rod 11 is movably installed with lifting frame 12, and the upper surface of lifting frame 12 side side bottom plate 1 is fixedly connected with plate sleeve 13, the upper surface of lifting frame 12 is fixedly provided with pressure sensor 14, and the upper surface of pressure sensor 14 is fixedly installed with adjusting roller 15.

[0022] The wing rod 5 and the pull rope 6 are symmetrically distributed about the longitudinal central axis of the passive plate 7, and the pull rope 6 is fixedly connected with the wing rod 5 and the passive plate 7, respectively.

[0023] The upper surface of the bottom plate 1 on the side of the pull rope 6 is fixedly connected with the support rod 9, and the outer wall of the support rod 9 is sleeved with the collar 10, so as to improve the smoothness of the movement of the pull rope 6.

[0024] The support rod 9 and the collar 10 form a rotating structure, and the collar 10 is attached to the pull rope 6, so as to facilitate the rotation of the collar 10 relative to the support rod 9 when the pull rope 6 moves, and the smooth movement of the pull rope 6.

[0025] The passive plate 7 and the driving plate 4 are rotatably connected with the lifting rod 11, and the lifting rod 11 and the lifting frame 12 are rotatably arranged, so as to facilitate the displacement of the lifting rod 11 when the passive plate 7 and the driving plate 4 move, thereby driving the lifting frame 12 to move.

[0026] The lifting frame 12 and the plate sleeve 13 form a sliding structure, and the side cross-sectional shape of the lifting frame 12 is set as a "匚" shape, which is convenient for the lifting frame 12 to move vertically relative to the plate sleeve 13 stably, so as to adjust the tension of the winding film.

[0027] Working principle: When using this biodegradable winding film tension adjusting device, first as Figures 1-4 shown, the user installs the device at the working position, then installs the biodegradable winding film on the device, and then the user connects the pressure sensor 14 and the cylinder 3 to the computer system at the same time. When the biodegradable winding film is transmitted, the limit roller 2 and the adjusting roller 15 ensure the stability of the winding film transmission. At the same time, the pressure sensor 14 monitors the tension of the winding film in real time. When the winding film needs to adjust the tension to ensure the stability of the transmission, the pressure sensor 14 transmits the data to the computer system. The user controls the cylinder 3 through the computer system according to the data transmitted by the pressure sensor 14. At this time, the cylinder 3 drives the active plate 4 to move, then the active plate 4 drives the wing rod 5 to move, and then the wing rod 5 drives the pull rope 6 to move. At the same time, the pull rope 6 drives the collar 10 to rotate relative to the support rod 9, so that the pull rope 6 drives the passive plate 7 to move stably. And the active plate 4 and the passive plate 7 drive the roller 8 to move relative to the bottom plate 1. At this time, the active plate 4 and the passive plate 7 move towards each other or in the opposite direction at the same time. Then the active plate 4 rotates relative to one end of the lifting rod 11 and drives the lifting rod 11 to move, and the other end of the lifting rod 11 rotates relative to the lifting frame 12 and drives the lifting frame 12 to move vertically relative to the plate sleeve 13. Similarly, the passive plate 7 also drives the lifting rod 11, so that the lifting frame 12 moves vertically stably. Then the lifting frame 12 drives the pressure sensor 14 and the adjusting roller 15 to move vertically, so as to loosen or tension the winding film, and then complete the automatic adjustment of the tension of the winding film. Therefore, the device improves the degree of automation, so as to facilitate the device to automatically adjust the tension of the winding film and increase the convenience of use of the device.
