Detailed implementation mode
[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.
[0030] Embodiment 1, please refer to Figures 1 to 4 , the present invention provides a technical solution: a BOPA film coiling machine, including a device body 1. A main shaft 101 is movably embedded on the right side inside the device body 1. A motor 102 is fixedly installed on the right side of the main shaft 101. A sleeve 103 is movably sleeved on the outer surface of the main shaft 101. First chutes 104 are opened on both outer surfaces of the main shaft 101. Both inner walls of the sleeve 103 are slidably connected to the inner surfaces of the first chutes 104. A crank 105 is movably embedded on the left side inside the sleeve 103. A screw 106 is fixedly installed on the right side of the crank 105. The screw 106 is threadedly connected to the left side inside the main shaft 101. The outer side of the sleeve 103 is movably connected with a plurality of support rods 107. The plurality of support rods 107 are divided into multiple groups in pairs. The other ends of the multiple groups of support rods 107 are all movably connected with a support plate 108. A plurality of connecting columns 109 are fixedly installed on the outer surface of the main shaft 101. Second chutes 110 are opened inside the plurality of connecting columns 109. First sliders 111 are slidably connected to the inner surfaces of the plurality of second chutes 110. A cutting member 2 is fixedly installed near the rear side of the top of the device body 1.
[0031] In this embodiment, the operator first sleeved the reel on the support plate 108, and rotated the screw rod 106 by rotating the crank 105 in the forward direction. When the screw rod 106 rotates, it can pull the sleeve 103 to slide to the right along the outer surface of the main shaft 101 through the first chute 104. When the sleeve 103 slides, it will squeeze the support rod 107, causing the support rod 107 to flip, and at the same time push the support plate 108 outward. Then, the support plate 108 drives the first slider 111 to slide outward along the inner surface of the second chute 110 on the connecting column 109, so that the support plate 108 can expand outward to fit the inner wall of the reel. After the reel is fixed, the operator can start the motor 102 through the power supply system of the motor 102 on the device body 1. When the motor 102 runs, it can drive the main shaft 101 to rotate through the output shaft, and then the main shaft 101 drives the reel to rotate through the support plate 108, so as to wind the film. Moreover, through the setting of the structure of the main shaft 101 and the support plate 108, not only can the support plate 108 expand according to the inner wall of the reel to adapt to reels of different diameters, but also this flexibility enables the device to be widely used in various film winding requirements. At the same time, through the design of driving the main shaft 101 to rotate by the motor 102, the film winding process becomes more automated, improving the work efficiency.
[0032] Embodiment 2, as Figures 1 to 4 shown, the left sides of multiple first sliders 111 are fixedly installed on the right side of the support plate 108. Two first rollers 201 are movably embedded near the bottom inside the cutting member 2. Two third chutes 202 are opened on both sides inside the cutting member 2. The inner surfaces of the four third chutes 202 are all slidably connected with second sliders 203. The four second sliders 203 are divided into two groups in pairs. The opposite sides of the two groups of second sliders 203 are all movably connected with second rollers 204. The bottoms of the four second sliders 203 are all fixedly installed with return springs 205. Both sides of the top of the cutting member 2 are fixedly installed with electric push rods 206. The other ends of the four return springs 205 are all fixedly installed on the top of the device body 1. The bottoms of the two electric push rods 206 are fixedly installed with a cutting knife 207.
[0033] In this embodiment, the operator can first pull the second slider 203 upward so that it slides upward through the third chute 202. When the second slider 203 slides, it will drive the second roller 204 to rise and simultaneously pull the return spring 205 to extend. Then, the operator picks up one end of the film and passes it through the cutting member 2, and makes the bottom outer surface of the film fit against the top of the first roller 201. The operator then fixes one end of the film to the reel on the support plate 108. After the film is fixed, the operator can release the second slider 203, causing the return spring 205 to reset. While resetting, the return spring 205 can pull the second roller 204 downward through the second slider 203, so that the second roller 204 can fit against the top outer surface of the film. Then, the operator starts the motor 102 to wind the film. When the film is wound to an appropriate size, the operator can start the electric push rod 206 through the power supply system of the electric push rod 206. When the electric push rod 206 extends, it can drive the cutting knife 207 to descend, and then cut the film through the cutting knife 207. With the settings of the second roller 204 and the cutting knife 207, not only can the second roller 204 apply a constant pressure to the film under the action of the return spring 205 to ensure that the film maintains a uniform tension during the winding process, which helps to improve the winding quality and avoid wrinkles or slack caused by uneven tension, but also the electric push rod 206 can be automatically started after the film is wound to an appropriate size, reducing the error and time cost of manual cutting. This automatic cutting method improves the production efficiency and cutting quality.
[0034] Working principle: During use, the operator first sleeved the reel on the support plate 108. When the forward-rotating crank 105 drives the screw rod 106 to rotate, the screw rod 106 can pull the sleeve 103 to slide to the right along the outer surface of the main shaft 101 through the first chute 104 when rotating. When the sleeve 103 slides, it will squeeze the support rod 107, causing the support rod 107 to flip and simultaneously push the support plate 108 outward. Then, the support plate 108 drives the first slider 111 to slide outward along the inner surface of the second chute 110 on the connecting column 109, enabling the support plate 108 to expand outward to fit the inner wall of the reel. After the reel is fixed, the operator can start the motor 102 through the power supply system of the motor 102 on the device body 1. When it operates, it can drive the main shaft 101 to rotate through the output shaft, and then the main shaft 101 drives the reel to rotate through the support plate 108, thereby winding the film. Moreover, due to the structure of the main shaft 101 and the support plate 108, not only can the support plate 108 expand according to the inner wall of the reel to adapt to reels of different diameters, but this flexibility also enables the device to be widely used in various film winding requirements. At the same time, the design of driving the main shaft 101 to rotate by the motor 102 makes the film winding process more automated and improves work efficiency. During use, the operator can first pull the second slider 203 upward, causing it to slide upward through the third chute 202. When the second slider 203 slides, it will drive the second roller 204 to rise and simultaneously pull the return spring 205 to extend. Then, the operator picks up one end of the film and passes it through the cutting member 2, and makes the outer surface of the bottom of the film fit the top of the first roller 201. The operator then fixes one end of the film to the reel on the support plate 108. After the film is fixed, the operator can release the second slider 203, enabling the return spring 205 to reset. When it resets, it can pull the second roller 204 to descend through the second slider 203, so that the second roller 204 can fit the outer surface of the top of the film. Then, the operator starts the motor 102 to wind the film. When the film is wound to the appropriate size, the operator can start the electric push rod 206 through the power supply system of the electric push rod 206. When it extends, it can drive the cutting knife 207 to descend, thereby cutting the film through the cutting knife 207. Moreover, due to the structure of the second roller 204 and the cutting knife 207, not only can the second roller 204 apply a constant pressure to the film under the action of the return spring 205 to ensure that the film maintains a uniform tension during the winding process, which helps improve the winding quality and avoid wrinkles or slack caused by uneven tension, but also the electric push rod 206 can be automatically started after the film is wound to the appropriate size, reducing the error and time cost of manual cutting. This automated cutting method improves production efficiency and cutting quality.

Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
