[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a guiding device for plastic film production, including a frame 1 and a roller 2. There are two frames 1. The roller 2 is disposed between the upper ends of the two frames 1 and is rotatably connected to the two frames 1. A cavity is opened inside the roller 2. Limiting rings 3 are sleeved on the left and right end surfaces of the roller 2. The two limiting rings 3 are slidably connected to the roller 2. A sliding rod 4 is provided inside the roller 2. The left and right ends of the sliding rod 4 are fixedly connected to the left and right side surfaces inside the roller 2, respectively. Adjusting devices 5 are provided on the left and right sides inside the roller 2. The positions of the two adjusting devices 5 and the two limiting rings 3 correspond to each other.

[0022] refer to Figure 1 , Figure 2 and Figure 3 The adjusting device 5 includes a box body 51, a locking component 52, a linkage component 53, and a control component 54. The box body 51 is located inside the roller body 2 on the left side and is fitted onto the surface of the slide rod 4 and is movably connected to the slide rod 4. There are four locking components 52, which are evenly arranged around the right end of the box body 51. The linkage component 53 is located to the left of the four locking components 52. The control component 54 is located at the upper rear side of the linkage component 53.

[0023] The above solution is adopted: by setting the adjustment device 5, the position of the limiting ring 3 can be adjusted and positioned, which facilitates the quick adjustment of the position of the limiting ring 3 according to the plastic film of different widths.

[0024] refer to Figure 3 and Figure 4The locking assembly 52 includes a positioning rod 521, a lock head 522, a push spring 523, and a pressure rod 524. There are two positioning rods 521, both of which are located inside the upper part of the box body 51 and are fixedly connected to the upper and lower inner walls of the upper part of the box body 51, respectively. The lock head 522 is sleeved on the upper part of the two positioning rods 521 and is slidably connected to the two positioning rods 521. The upper part of the lock head 522 extends out of the box body 51 and is movably connected to the box body 51. The push spring 523 is located below the lock head 522 and is fixedly connected to the lower surface of the lock head 522 and the inner wall of the box body 51, respectively. The pressure rod 524 is fixedly connected to the left surface of the lock head 522.

[0025] The above solution involves setting a locking component 52 to engage with the adjustment groove 6, thereby enabling rapid adjustment and positioning of the limit ring 3.

[0026] refer to Figure 4 The linkage component 53 includes a turntable 531, a travel groove 532, and a toothed sleeve 533. The turntable 531 is fitted onto the inner wall surface of the box body 51 and is rotatably connected to the box body 51. There are four travel grooves 532, which are evenly distributed around the right surface of the turntable 531. The positions of the four travel grooves 532 and the four pressure rods 524 correspond to and are compatible with each other. The left ends of the four pressure rods 524 extend into the four travel grooves 532 and are movably connected to the travel grooves 532. The toothed sleeve 533 is fitted onto the inner wall surface of the box body 51 and is rotatably connected to the box body 51. Its right end is fixedly connected to the left surface of the turntable 531.

[0027] The above solution is adopted: by setting up a linkage component 53, it is used to drive the locking component 52, which has the function of simultaneously linking the four lock heads 522 to move synchronously.

[0028] refer to Figure 4 The control component 54 includes a support rod 541, a rack 542, and a pull button 543. There are two support rods 541, both of which are located above the toothed sleeve 533 and are fixedly connected to the inner walls of the front and rear sides of the box body 51, respectively. The rack 542 is sleeved on the surface of the two support rods 541 and is slidably connected to the support rods 541 and engaged with the toothed sleeve 533. The pull button 543 is fixedly connected to the front side of the rack 542 and extends out of the front side to form a roller body 2, which is movably connected to the roller body 2 and the box body 51.

[0029] The above scheme is adopted: by setting up a control component 54, which is used to drive and control the adjustment device 5, it can simultaneously control the four locking components 52 to release the fixation of the limit ring 3 by driving the linkage component 53, thereby achieving the function of quickly releasing the fixation for adjustment.

[0030] refer to Figure 2Several adjustment grooves 6 are evenly distributed around the inner wall of the roller body 2. The positions of the adjustment grooves 6 correspond to and are compatible with the positions of the locking components 52.

[0031] The above solution is adopted: by evenly opening several adjustment grooves 6 around the inner wall of the roller body 2, the locking component 52 is engaged and locked, thereby achieving rapid positioning of the limit ring 3 during adjustment.

[0032] refer to Figure 2 Connectors 7 are fixedly connected to the upper and lower surfaces of the box body 51 respectively. The ends of the two connectors 7 that are far apart from each other extend out of the box body 51 and are fixedly connected to the inner wall of the limiting ring 3. The connectors 7 are movably connected to the roller body 2.

[0033] The above solution is adopted: By setting connectors 7 on the upper and lower surfaces of the box body 51 respectively, it is used to connect with the limiting ring 3, thereby fixing the adjustment device 5 to the limiting ring 3.

[0034] The working principle of this utility model:

[0035] During adjustment, pull the knob 543 forward to move the rack 542 forward on the surface of the support rod 541. Simultaneously, the rack 542 rotates its sleeve 533, which in turn rotates the turntable 531. This rotation of the turntable 531 then rotates the four travel grooves 532, which in turn press against the internal pressure rod 524 through the inner wall. This pressure causes the locking head 522 to move downward on the surface of the positioning rod 521. The movement simultaneously compresses the push spring 523, causing the upper end of the lock head 522 to move out of the adjustment groove 6, thus releasing the fixation. Then, the movement adjustment is achieved by pulling the limiting ring 3 on the surface of the roller body 2. The movement of the limiting ring 3 will drive the box body 51 to move on the surface of the slide rod 4 through the connecting piece 7. After the movement adjustment is such that the lock head 522 corresponds to the appropriate adjustment groove 6, the pull button 543 is released, and the push spring 523 will rebound to push the upper end of the lock head 522 into the corresponding adjustment groove 6, thereby completing the rapid adjustment and positioning of the limiting ring 3.

[0036] In summary, this guiding device for plastic film production, through the coordinated use of a frame 1, roller 2, limiting ring 3, slide bar 4, adjusting device 5, box 51, locking assembly 52, positioning rod 521, lock head 522, push spring 523, pressure rod 524, linkage assembly 53, turntable 531, stroke groove 532, gear sleeve 533, control assembly 54, support rod 541, rack 542, pull button 543, adjusting groove 6, and connecting piece 7, solves the problem that existing guide rollers typically use bolts and fasteners for positioning and fixing the limiting rings on both sides. This requires repeatedly loosening and reinstalling the bolts to adjust the position of the limiting rings according to different widths of plastic film, which is time-consuming, labor-intensive, and affects work efficiency.
