When the protective film is laid, the stabilizing roller 224 will be driven to rotate. When the tension on the protective film is too large, the stabilizing roller 224 will be squeezed to move downward, so as to avoid the protective film being torn due to excessive tension during the laying process.

[0028] A spring No. 1 229 is arranged between the lifting rod 222 and the inner wall of the stabilizing groove 223, and spring pieces 2210 are directly arranged between the inner wall of the contraction groove 227 and the stabilizing block 226. The stabilizing roller 224 moves downward to drive the lifting rod 222 to move downward, and the lifting rod 222 moves downward to squeeze the spring No. 1 229 to contract, thereby realizing the stable laying of the protective film, preventing the protective film from being torn due to excessive tension during the laying process, thereby increasing unnecessary losses and subsequent maintenance costs.

[0029] The side of the stabilizing block 226 away from the spring piece 2210 is set as an arc surface, and the lifting plate 225 is slidably connected to the adjustment plate 3. When the lifting plate 225 continues to move, the stabilizing block 226 will contact and limit the limiting groove 228 again under the action of the spring piece 2210, which can effectively prevent the stabilizing roller 224 from shaking due to vibration when the equipment is working, thereby causing uneven laying of the protective film, and further improve the stability of the protective film during laying.

[0030] The anti-wrinkle device also includes a support rod 231, an arc rod 232, a receiving shaft 233, an auxiliary roller 234, a pressure plate 235 and a rubber strip 236. During the laying process, the protective film will squeeze the auxiliary roller 234 to rotate around the support rod 231. The rotation of the auxiliary roller 234 drives the receiving shaft 233 to rotate. The support rod 231 is fixedly installed on the side of the lifting plate 225, the arc rod 232 is rotatably installed on the circumferential surface of the support rod 231, the receiving shaft 233 is fixedly passed through the left and right walls of the arc rod 232, the auxiliary roller 234 is rotatably installed on the circumferential surface of the receiving shaft 233, the surface of the lifting plate 225 is provided with a lifting groove 237, the pressure plate 235 is slidably installed on the inner wall of the lifting groove 237, and the rubber strip 236 is fixedly installed on the circumferential surface of the auxiliary roller 234. The auxiliary roller 234 and the stabilizing roller 224 will clamp the protective film, which can effectively prevent the stabilizing roller 224 from continuing to rotate when the laying is stopped, causing the protective film to accumulate.

[0031] A No. 2 spring 238 is arranged between the pressure plate 235 and the inner wall of the lifting groove 237. The bottom of the pressure plate 235 contacts the circumferential surface of the receiving shaft 233. When the receiving shaft 233 rotates, it squeezes the pressure plate 235 to move upward, and the pressure plate 235 moves upward to squeeze the No. 2 spring 238 to contract.

[0032] There are several rubber strips 236, and the shape of several rubber strips 236 is set to be spiral. Several rubber strips 236 are symmetrically distributed around the center of the supporting shaft 233. When the rubber strips 236 rotate, the spiral shape will cause the protective film to move to both sides of the adjustment plate 3, thereby effectively avoiding wrinkles on the protective film during the laying process, making the protective film smoother during the laying process.

[0033] When this embodiment is working: when the adjustment plate 3 moves, it drives the fixed rod 221 to move, the movement of the fixed rod 221 drives the lifting rod 222 to move, the movement of the lifting rod 222 drives the stabilizing roller 224 to move, and the movement of the stabilizing roller 224 drives the protective film to move. In this process, when the protective film is laid, it will drive the stabilizing roller 224 to rotate. When the tension on the protective film is too large, it will squeeze the stabilizing roller 224 to move downward, and the downward movement of the stabilizing roller 224 drives the lifting rod 222 to move downward. The lifting rod 222 moves downward to squeeze the No. 1 spring 229 to contract, thereby achieving stable laying of the protective film, avoiding excessive tension on the protective film during the laying process. When the lifting plate 225 moves, it drives the stabilizing block 226 to move. When the stabilizing block 226 moves, it squeezes the spring piece 2210 to contract under the action of the limiting groove 228. When the lifting plate 225 continues to move, the stabilizing block 226 will contact and limit the limiting groove 228 again under the action of the spring piece 2210, which can effectively prevent the stabilizing roller 224 from shaking due to vibration when the equipment is working, thereby causing uneven laying of the protective film, and further improve the stability of the protective film during laying.

[0034] During the laying process, the protective film will squeeze the auxiliary roller 234 to rotate around the support rod 231. The rotation of the auxiliary roller 234 drives the receiving shaft 233 to rotate. When the receiving shaft 233 rotates, it squeezes the pressure plate 235 to move upward. The pressure plate 235 moves upward to squeeze the No. 2 spring 238 to contract. When the laying is stopped, the auxiliary roller 234 and the stabilizing roller 224 will clamp the protective film under the action of the No. 2 spring 238, which can effectively prevent the stabilizing roller 224 from continuing to rotate when the laying is stopped, causing the protective film to accumulate, thereby increasing the subsequent maintenance cost. At the same time, when the auxiliary roller 234 rotates, it will drive the rubber strip 236 to rotate. When the rubber strip 236 rotates, the spiral shape will cause the protective film to move to both sides of the adjustment plate 3, thereby effectively preventing the protective film from wrinkling during the laying process, making the protective film smoother during the laying process.
