[0002] In the production process, cast film is generally directly extruded into a continuous strip with a relatively wide transverse width.

Each vertical plate has symmetrically arranged through holes, within which a connecting shaft is detachably mounted. Multiple partition plates are detachably mounted on the outer wall of each symmetrically arranged connecting shaft, and a cutting blade is provided on the left end face of each partition plate.

Detailed Implementation

[0026] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0027] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 4 As shown in the figure, the present invention provides a slitting machine for CPP cast film production, including a main body 1 and a winding assembly 2, and a vertical plate 3 for supporting the winding assembly 2. A support block 4 is fixedly connected to the front side of the vertical plate 3, a reduction motor 5 is fixedly connected to the left side of the support block 4, a transmission shaft 6 is provided on the right side of the support block 4, a support frame 7 is fixedly connected to the surface of the transmission shaft 6, a pressing device 8 is provided on the rear side of the support frame 7, and a cleaning device 9 that works in conjunction with the pressing device 8 is provided on the top of the support frame 7.

[0029] refer to Figure 2 The left side of the drive shaft 6 passes through the support block 4 and extends to the outside of the support block 4, where it is fixedly connected to the output end of the geared motor 5.

[0030] The above solution is adopted: by setting a reduction motor 5 and a transmission shaft 6, the support frame 7 can be driven to rotate, and the support frame 7 synchronously drives the pressing device 8 and the cleaning device 9 to rotate to the work position.

[0031] refer to Figure 2 and Figure 3 The left and right sides of the top of the support frame 7 are fixedly connected to sliding columns 10 that work with the cleaning device 9.

[0032] The above solution is adopted: by setting the sliding column 10, the lifting plate 901 can be limited, which facilitates the lifting plate 901 to rise and fall.

[0033] refer to Figure 4The pressing device 8 includes a positioning frame 801, a pressing roller 802 is provided on the inner side of the positioning frame 801, and a limit post 803 is provided on the left and right sides of the front side of the positioning frame 801. A spring 804 is sleeved on the surface of the limit post 803, and a push plate 805 is provided on the front side of the limit post 803. A squeezing hole 806 is opened on the opposite side of the two push plates 805.

[0034] The above solution involves setting up a pressing device 8 to press the CPP cast film, preventing it from becoming loose during winding.

[0035] refer to Figure 4 The cleaning device 9 includes a lifting plate 901, a cleaning scraper 902 is provided on the front side of the bottom of the lifting plate 901, and a push column 903 is provided on the rear side of the left and right sides of the lifting plate 901.

[0036] The above solution allows for the cleaning of debris that may be generated on the surface of the CPP cast film by setting up the cleaning device 9, which facilitates the winding of the CPP cast film.

[0037] refer to Figure 3 and Figure 4 Both ends of the pressing roller 802 are rotatably connected to the inner side of the positioning frame 801. The rear side of the limiting post 803 is fixedly connected to the positioning frame 801. The front side of the limiting post 803 passes through the support frame 7 and extends to the outer side of the support frame 7 and is fixedly connected to the push plate 805. The front and rear sides of the spring 804 are fixedly connected to the positioning frame 801 and the support frame 7, respectively.

[0038] The above scheme is as follows: By setting the positioning frame 801, the pressure roller 802 can be supported. By setting the pressure roller 802, the CPP cast film can be pressed. By setting the limiting post 803, the positioning frame 801 and the spring 804 can be supported and limited. By setting the spring 804, the force released after compression can push the positioning frame 801 and the pressure roller 802 backward, so that the pressure roller 802 can adaptively adjust according to the film roll thickness and continuously press the CPP cast film. By setting the push plate 805 and the extrusion hole 806, the push plate 805 can extrude the push post 903 through the extrusion hole 806 on its surface during the movement of the push plate 805, and push the push post 903 upward.

[0039] refer to Figure 3 and Figure 4The rear side of the lifting plate 901 is sleeved on the surface of the sliding column 10 and is slidably connected to the sliding column 10 through a linear bearing. The top of the cleaning scraper 902 is fixedly connected to the lifting plate 901. The side of the pushing column 903 close to the lifting plate 901 is fixedly connected to the lifting plate 901. The side of the pushing column 903 away from the lifting plate 901 passes through the extrusion hole 806 and extends into the inner cavity of the extrusion hole 806 to contact the inner wall of the extrusion hole 806.

[0040] The above solution is adopted: by setting up a lifting plate 901, the cleaning scraper 902 can be raised and lowered. By setting up a cleaning scraper 902, the debris on the surface of the CPP cast film can be scraped off. By setting up a push column 903, the lifting plate 901 can be raised and lowered.

[0041] The working principle of this utility model:

[0042] When the slit CPP cast film is wound up, the geared motor 5 is started to drive the transmission shaft 6 to rotate, which drives the pressing device 8 on the rear side of the support frame 7 and the cleaning device 9 on the top to rotate synchronously. After the pressing device 8 and the cleaning device 9 reach the appropriate position, the geared motor 5 stops, and the support frame 7 stops rotating. Then, the winding assembly 2 starts to wind up the slit CPP cast film. During winding, the thickness of the CPP cast film roll will gradually increase, and the film roll will push the pressing roller 802 forward, which will drive the positioning frame 801 forward synchronously. The positioning frame 801 pushes the push plate 805 forward through the limiting post 803 and compresses the spring 804. The elastic force released after the spring 804 is compressed will push the positioning frame 801 and the pressing roller 802 backward in the opposite direction, so that the pressing roller 802 keeps in contact with the surface of the film roll, realizing the self-adaptive pressing of the pressing roller 802 on the film roll and preventing loosening. The cleaning scraper 902 adheres to the surface of the film roll and scrapes away the burrs generated during slitting. When the push plate 805 moves forward, the extrusion holes 806 on its surface extrude the push column 903. The resulting extrusion force pushes the push column 903 upward. The push column 903 drives the lifting plate 901 to move upward along the sliding column 10, so that the cleaning scraper 902 moves upward synchronously with the thickening of the film roll and maintains continuous adhesion to the surface of the film roll to scrape away the burrs on the surface of the film roll.

[0043] In summary, this CPP cast film slitting machine, through the coordinated use of support block 4, reduction motor 5, transmission shaft 6, support frame 7, pressing device 8, and cleaning device 9, solves the problem that existing CPP cast film slitting machines lack the function of pressing and cleaning the surface of the CPP cast film. The lack of pressing function may cause the CPP cast film to become loose during the winding process after slitting, and melting burrs may be generated during the slitting process. If the burrs are not cleaned in time, they may embed into the film surface, causing scratches or uneven defects.
