However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a plastic film processing and winding machine, including: a bottom plate 1; a detection component 5, the detection component 5 is fixedly connected to the top of the bottom plate 1, the detection component 5 includes a fixed frame 501, the inner surface of the fixed frame 501 is fixedly connected to a top plate 502, a plurality of groups of telescopic rods 503 are fixedly connected to the bottom of the top plate 502 at equal intervals, a connecting seat 505 is fixedly connected between the lower end surfaces of the plurality of groups of telescopic rods 503, a connecting seat 505 is rotatably connected to the inner surface of the connecting seat 505, a first conductive wheel 507 is fixedly connected to the outer surface of the connecting shaft 506, a supporting shaft 508 is rotatably connected to the inner surface of the fixed frame 501, a second conductive wheel 509 is fixedly connected to the end surface of the supporting shaft 508, a second spring 512 is symmetrically fixedly connected to the top of the fixed plate 511, a brush 513 is fixedly connected between the upper end surfaces of the two second springs 512, the top of the brush 513 is in contact with the inner surface of the second conductive wheel 509, a bracket 2 is fixedly connected to the top of the bottom plate 1, and the bracket 2 is fixedly connected to the outer surface of the motor 3, the output end of the motor 3 passes through the bracket 2 and extends to the front side, the output end of the motor 3 is fixedly connected to the winding roller 4, the outer surface of the telescopic rod 503 is sleeved with a first spring 504, the first spring 504 is fixedly connected between the top plate 502 and the connecting seat 505, the first conductive wheel 507 is located on the upper side of the second conductive wheel 509, the outer surface of the first conductive wheel 507 is in contact with the outer surface of the second conductive wheel 509, the inner surface of the fixing frame 501 is symmetrically fixedly connected to the fixing rod 510, the end surfaces of the two fixing rods 510 are fixedly connected to the fixing plate 511, the fixing plate 511 is located inside the second conductive wheel 509, the top of the fixing plate 511 is fixedly connected to the resistance switch 514 near the lower side of the brush 513, the top of the fixing plate 511 is fixedly connected to the alarm 515, the resistance switch 514 is connected to the brush 513 through a power line, and the alarm 515 is connected to the resistance switch 514 through a power line.
[0024] The effect achieved by the entire embodiment 1 is that when the plastic film is wound, after the plastic film passes between the first conductive wheel 507 and the second conductive wheel 509, the plastic film is wound around the winding roller 4. The starting motor 3 can drive the winding roller 4 to rotate to wind the plastic film. While the plastic film is pulled and wound, the plastic film passes between the first conductive wheel 507 and the second conductive wheel 509. The first conductive wheel 507 and the second conductive wheel 509 can rotate freely, which can reduce the friction force and avoid the wear of the plastic film during the winding process. When the plastic film passes between the first conductive wheel 507 and the second conductive wheel 509 and is sent out, the damage detection of the plastic film can be performed. Since the plastic film is not conductive, after the first conductive wheel 507 and the second conductive wheel 509 are attached, it will conduct electricity, resulting in the resistance switch 514 The resistance of the plastic film changes to achieve control. When the plastic film passes through the first conductive wheel 507 and the second conductive wheel 509 and there is damage, the first spring 504 will use the resilience of the first spring 504 to apply downward pressure to the first conductive wheel 507. Therefore, when the first conductive wheel 507 passes the damaged position of the plastic film, the first conductive wheel 507 will directly adhere to the surface of the second conductive wheel 509. After the second conductive wheel 509 contacts the conductor, the resistance switch 514 will detect the resistance change through the connection of the brush 513. After the resistance switch 514 changes, the alarm 515 will be controlled to run. After the alarm 515 is running, the motor 3 can be controlled to stop running and an alarm can be issued to remind the staff, thereby realizing automatic detection of whether the plastic film is damaged during the winding process, and the winding can be stopped in time and the staff can be reminded, thereby effectively improving the product quality of plastic film processing.
[0025] Embodiment 2, as Figure 1-Figure 4 As shown, multiple groups of telescopic rods 503 are equidistantly fixedly connected to the bottom of the top plate 502, and connecting seats 505 are fixedly connected between the lower end surfaces of the multiple groups of telescopic rods 503. The inner surface of the connecting seat 505 is rotatably connected to a connecting shaft 506, and the outer surface of the connecting shaft 506 is fixedly connected to a first conductive wheel 507.
[0026] The effect achieved by the entire embodiment 2 is that, through the use of multiple groups of first conductive wheels 507 in conjunction with a single second conductive wheel 509 at the bottom, the multiple first conductive wheels 507 can be displaced individually to fit the damaged position of the plastic film and fit the second conductive wheel 509 to achieve detection. Even when there is a small damaged position in the plastic film, it can be detected, thereby improving the accuracy of the damage detection structure.
[0027] Working principle: When the plastic film is wound, the plastic film is passed between the first conductive wheel 507 and the second conductive wheel 509, and then the plastic film is wound around the winding roller 4. The starting motor 3 can drive the winding roller 4 to rotate and wind the plastic film. While the plastic film is pulled and wound, the plastic film passes between the first conductive wheel 507 and the second conductive wheel 509. The first conductive wheel 507 and the second conductive wheel 509 can rotate freely, which can reduce friction and avoid wear of the plastic film during the winding process. When the plastic film is sent out between the first conductive wheel 507 and the second conductive wheel 509, the damage detection of the plastic film can be performed. Since the plastic film is not conductive, after the first conductive wheel 507 and the second conductive wheel 509 are attached, they will conduct electricity, causing the resistance of the resistance switch 514 to change, thereby realizing control. When the plastic film is damaged at the position where it passes through the first conductive wheel 507 and the second conductive wheel 509, the rebound of the first spring 504 is utilized. The force will exert pressure downward on the first conductive wheel 507, so when the first conductive wheel 507 passes the damaged position of the plastic film, the first conductive wheel 507 will directly fit on the surface of the second conductive wheel 509. After the second conductive wheel 509 contacts the conductor, the brush 513 will be connected to enable the resistance switch 514 to detect the resistance change. After the resistance switch 514 changes, the alarm 515 will be controlled to operate. After the alarm 515 is operated, the motor 3 can be controlled to stop running and an alarm can be issued to remind the staff, thereby realizing automatic detection of whether the plastic film is damaged during the winding process, and the winding can be stopped in time and the staff can be reminded, thereby effectively improving the product quality of the plastic film processing. By using multiple groups of first conductive wheels 507 in conjunction with the single second conductive wheel 509 at the bottom, multiple first conductive wheels 507 can fit the damaged position of the plastic film and independently displace and fit the second conductive wheel 509 to achieve detection. When there is a small damaged position in the plastic film, it can also be detected, thereby improving the accuracy of the damage detection structure.
