[0024] Reference Figure 2 This embodiment provides an anti-POL floating device, including a guide roller body 1 and a guide assembly 2. The guide assembly 2 includes a first guide plate 21, a first fixing rod 22, a first support rod 23, a second guide plate 24, a second fixing rod 25, and a second support rod 26. The first guide plate 21 and the second guide plate 24 are respectively disposed on both sides of the guide roller body 1. The first guide plate 21 is fixedly connected to one end of the first fixing rod 22, and the other end of the first fixing rod 22 is fixedly connected to the first support rod 23. The second guide plate 24 is fixedly connected to one end of the second fixing rod 25, and the other end of the second fixing rod 25 is fixedly connected to the second support rod 26.

[0025] In this preferred embodiment, the first support rod 23 is used to fix the first fixing rod 22, the first fixing rod 22 is used to fix the first guide plate 21, the second support rod 26 is used to fix the second fixing rod 25, and the second fixing rod 25 is used to fix the second guide plate 24. When the roll material POL passes through the guide roller body 1, the protective film on the roll material POL is tightly attached to the surface of the guide roller. During the movement of the roll material POL, the cutting line of the roll material POL moves to the tangent position between the guide roller body 1 and the roll material POL. The first guide plate 21 or the second guide plate 24 will press down on the cutting line position of the roll material POL to prevent the roll material POL from separating from the protective film. This avoids the roll material POL from floating up significantly, which could cause the POL to malfunction at this point in the equipment movement. This also prevents the protective film from not covering the roll material POL, which could lead to scratches or the adhesion of impurities and dust to the roll material POL. This prevents the roll material POL from separating from the protective film and affecting the quality of the roll material POL.

[0026] Example 2

[0027] Reference Figures 2 to 6 This embodiment is based on the previous embodiment, but differs from the previous embodiment in that...

[0028] It also includes a support component 3, which includes a support plate 31, and the two ends of the guide roller body 1 are respectively rotatably connected to the support plate 31.

[0029] In this embodiment, the support plate 31 is preferably used to fix the position of the guide roller body 1. The rotation of the guide roller body 1 is beneficial to guiding the roll material POL through the surface of the guide roller body 1.

[0030] Reference Figure 2It also includes an adjustment component 4, which includes a first adjustment member 41 and a second adjustment member 42. The first adjustment member 41 and the second adjustment member 42 have the same structure and are symmetrically arranged on both sides of the guide roller body 1. The first adjustment member 41 and the second adjustment member 42 respectively include a first slider 401 and a second slider 402. The first slider 401 is fixedly connected to both ends of the first support rod 23 or the second support rod 26. The second slider 402 has a first groove 402a. The first slider 401 is slidably connected to the inner wall of the first groove 402a. The support plate 31 has a second groove 311. The outer wall of the second slider 402 is slidably connected to the inner wall of the second groove 311.

[0031] In this preferred embodiment, the first adjusting member 41 and the second adjusting member 42 are used to adjust the positions of the first support rod 23 and the second support rod 26, so that the first guide plate 21 and the second guide plate 24 are more in contact with the surface of the roll material POL, preventing the roll material POL from separating from the protective film and avoiding the roll material POL from floating up significantly, which could cause the POL to malfunction at this point in the equipment movement. The first slider 401 can slide on the inner wall of the first slide groove 402a, and the second slider 402 can slide on the inner wall of the second slide groove 311.

[0032] Reference Figure 5 and Figure 6 The first slider 401 is fixedly connected to the first limiting strip 401a, and the inner wall of the first sliding groove 402a is provided with a first limiting groove 402b corresponding to the first limiting strip 401a, and the first limiting strip 401a is slidably connected to the inner wall of the first limiting groove 402b.

[0033] In this preferred embodiment, the cooperation between the first limiting strip 401a and the first limiting groove 402b helps to improve the stability of the first slider 401 when sliding on the inner wall of the first groove 402a.

[0034] Reference Figure 5 The second slider 402 is fixedly connected to the outer wall of the second limiting strip 402c. The inner wall of the second sliding groove 311 is provided with a second limiting groove 3111 corresponding to the second limiting strip 402c, and the second limiting strip 402c is slidably connected to the inner wall of the second limiting groove 3111.

[0035] In this preferred embodiment, the cooperation between the second limiting strip 402c and the second limiting groove 3111 helps to improve the stability of the second slider 402 when sliding on the inner wall of the second groove 311.

[0036] Reference Figures 2 to 5The first slider 401 is fixedly connected to one end of the first spring 403, the other end of the first spring 403 is fixedly connected to the inner wall of the second slide groove 311, the inner wall of the second slide groove 311 is fixedly connected to the locking block 404, the outer wall of the second slider 402 is fixedly connected to one end of the second spring 406, and the other end of the second spring 406 is fixedly connected to the locking block 404.

[0037] In this preferred embodiment, under the action of the first spring 403, the two first sliders 401 on the first adjusting member 41 and the second adjusting member 42 tend to move away from each other. At this time, the first support rod 23 drives the first fixed rod 22 and the first guide plate 21 to move closer to the guide roller body 1, and the second support rod 26 drives the second fixed rod 25 and the second guide plate 24 to move closer to the guide roller body 1. The first guide plate 21 and the second guide plate 24 cooperate with the guide roller body 1 to press against the guide roller body 1. When the roll material POL passes through the guide roller body 1, the roll... The protective film on the roll POL is closely attached to the surface of the guide roller. During the movement of the roll POL, the cutting line of the roll POL moves to the tangent position between the guide roller body 1 and the roll POL. The first guide plate 21 or the second guide plate 24 will press down on the cutting line position of the roll POL to prevent the roll POL from separating from the protective film. This avoids the roll POL from floating up significantly, which could cause the POL to stop moving at this point. It also prevents the protective film from not covering the roll POL, which could cause scratches or dirt to adhere to the roll POL. This prevents the roll POL from separating from the protective film and affecting the quality of the roll POL.

[0038] Under the action of the second spring 406, the second slider 402 moves downward, which will drive the first slider 401 to move downward, so that the first fixing rod 22 and the second fixing rod 25 can press the cutting line position of the roll material POL and prevent the roll material POL from separating from the protective film.

[0039] Reference Figure 2 The first spring 403 is sleeved on the first telescopic rod 407, and the second spring 406 is sleeved on the second telescopic rod 408.

[0040] In this preferred embodiment, the first telescopic rod 407 can prevent the first spring 403 from being bent out of shape, and the second telescopic rod 408 can prevent the second spring 406 from being bent out of shape.

[0041] Reference Figure 3 The first telescopic rod 407 and the second telescopic rod 408 are respectively connected to the fixed pipe 409 through the connecting pipe 405. The fixed pipe 409 is equipped with an electric valve 409a and an air inlet pipe 409b.

[0042] In this preferred embodiment, when the electric valve 409a is open, the inside of the fixed pipe 409 is connected to the outside. At this time, the first telescopic rod 407 and the second telescopic rod 408 will extend and retract with the first spring 403 and the second spring 406. When the electric valve 409a is closed, the other end of the air intake pipe 409b is connected to the existing air pump. When the air pump draws air from the inside of the air intake pipe 409b, negative pressure acts on the fixed pipe 409 and, through the connecting pipe 405, on the first telescopic rod 407 and the second telescopic rod 408, causing them to retract. When the air pump pumps air into the air intake pipe 409b, the first telescopic rod 407 and the second telescopic rod 408 extend.

[0043] Reference Figure 4 The support component 3 also includes a fixing plate 32, and the fixing plate 32 is fixedly connected to both ends of the fixing tube 409, and the fixing plate 32 is fixedly connected to the support plate 31.

[0044] In this preferred embodiment, the fixing plate 32 can support the fixing tube 409.

[0045] Reference Figure 2 The first fixing rod 22 and the second fixing rod 25 are semi-circular.

[0046] In this embodiment, the first fixing rod 22 and the second fixing rod 25 are preferably semi-circular to facilitate the fit of the guide roller body 1. When the cutting line of the roll material POL moves to the gap between the guide roller body 1 and the first fixing rod 22 and the second fixing rod 25, the first fixing rod 22 and the second fixing rod 25 can press down the cutting line position of the roll material POL to prevent the roll material POL from separating from the protective film.
