[0040] Reference Figure 1-Figure 5A casting machine for composite film production with dust removal function, comprising a machine platform 1, a roller assembly 2, an upper dust removal assembly 3 and a lower dust removal assembly 4, wherein the upper dust removal assembly 3 is used to remove dust from the upper end of the casting film, and the lower dust removal assembly 4 is used to remove dust from the lower end of the casting film, and the roller assembly 2 comprises a stretching roller 21, a traction roller 22 and a pressure roller 23 which are sequentially distributed, and the stretching roller 21, the traction roller 22 and the pressure roller 23 are used to pull the casting film;

[0041] The upper dust removal assembly 3 is arranged in the machine platform 1 and is located above the pressure roller 23, and the lower dust removal assembly 4 is arranged in the machine platform 1 and is located below the traction roller 22;

[0042] The upper dust removal assembly 3 includes a push rod component 31, a support component 32 and a cleaning roller 33. A placement groove 11 is provided on one side of the machine table 1. The push rod component 31 is arranged in the placement groove 11 and connected to the support component 32. The cleaning roller 33 is installed in the support component 32. An adsorption film 331 is provided on the outer peripheral surface of the cleaning roller 33. The adsorption film 331 is an electrostatic adsorption film in the prior art. The push rod component 31 is a pneumatic push rod in the prior art. Through the cooperation of the push rod component 31 and the support component 32, the cleaning roller 33 is moved close to or away from the pressure roller 23, and a moving area for the casting film to pass through is formed between the cleaning roller 33 and the pressure roller 23. The casting film is located between the cleaning roller 33 and the pressure roller 23.

[0043] The lower end dust removal component 4 includes a hollow support 41, a screw component 42, a slide 43, a support rod 44 and a scraper component 45. The support 41 is arranged in the machine 1, and the screw component 42 is rotatably arranged in the support 41. One end of the screw component 42 passes through the support 41 and is equipped with a handwheel. The rotation of the handwheel can drive the screw component 42 to rotate. The support rod 44 is arranged on the support 41, and the scraper component 45 is sleeved on the support rod 44. Through the cooperation of the screw component 42 and the slide 43, the support rod 44 can move along the support 41 to make the scraper component 45 approach or move away from the traction roller 22.

[0044] Based on the above structure, the extruded cast film is sequentially pulled from the stretching roller 21 to the pressure roller 23 and brought into contact with the pulling roller 22. Since the newly extruded cast film first contacts the stretching roller 21, the stretching roller 21 will be adhered with colloid produced by the cast film after long-term use, which will cause the end of the subsequent cast film that contacts the stretching roller 21 to have colloid adhesion. Therefore, the lower end dust removal component 4 is arranged below the pulling roller 22. When the operator turns the hand wheel to drive the screw component 42 to rotate, the slide 43 drives the support rod 44 to move along the rotation direction of the screw component 42, so that the scraper component 45 is located below the cast film and abuts against its end face. The scraper component 45 can The impurities or dust attached to the bottom of the cast film are scraped off. Since the upper dust removal component 3 is located above the pressure roller 23, at the other end of the cast film away from the stretching roller 21, the support component 32 is driven by the push rod component 31 to move the cleaning roller 33 close to the pressure roller 23, and the cast film is clamped with the cooperation of the pressure roller 23, so that the outer peripheral surface of the cleaning roller 33 is in contact with the cast film, and the dust impurities above the cast film are adsorbed by the adsorption film 331. Through the cooperation of the upper dust removal component 3 and the lower dust removal component 4, the two end surfaces of the cast film can be dusted, thereby solving the problem that the dust impurities attached to the cast film will reduce the quality of the film product and affect the physical and chemical properties of the film.

[0045] In one embodiment, referring to Figure 1 and Figure 2 , and also includes a cooling component 5, the cooling component 5 includes a bearing seat 51 and a fan component 52, the bearing seat 51 is arranged in the machine 1 and is located on one side of the stretching roller 21, and a plurality of fan components 52 are arranged and are distributed on the bearing seat 51 at intervals, and the output end of the fan component 52 faces the stretching roller 21. Since the cast film is a plastic film produced by a casting method, which is to spread the molten plastic resin evenly on the stretching roller 21 through a casting head, and cool the cast film by pulling it, the cooling component 5 is arranged on one side of the stretching roller 21, and the cast film is blown and cooled by the fan component 52 in the cooling component 5, so that it can be quickly fixed, and dust is prevented from easily flowing into its surface when the cast film is not completely solidified.

[0046] In one embodiment, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5The supporting component 32 includes a connecting frame 321 and a mounting seat 322. The connecting frame 321 is arranged above the mounting seat 322 and connected to the push rod component 31. A shaft 3221 is arranged on one side of the mounting seat 322.

The cleaning roller 33 is installed in the mounting seat 322 by embedding the shaft 3221 into the recessed portion 332. The cleaning roller 33 is installed on the mounting seat 322 by embedding the recessed portion 332 into the shaft 3221. Due to the cooperation between the recessed portion 332 and the shaft 3221, the cleaning roller 33 can rotate in a circle with the shaft 3221 as the center.

[0047] A through opening 3222 is provided on the other side of the mounting seat 322, and a mounting hole 333 is provided on the side of the cleaning roller 33 corresponding to the opening 3222. When the opening 3222 and the mounting hole 333 are aligned, a latch passes through the opening 3222 and the mounting hole 333 to connect the cleaning roller 33 and the mounting seat 322. The mounting seat 322 and the other end of the cleaning roller 33 can be connected through the cooperation of the latch, so that the latch limits the mounting seat 322 and the cleaning roller 33, thereby improving the stability of the cleaning roller 33 when it contacts the cast film and avoiding shaking.

The tip of the blade portion 452 faces the traction roller 22. Since different types of cast films have different thicknesses, when the blade portion 452 can only maintain the same angle, there is a risk that the blade portion 452 will scratch the cast film. Therefore, through the cooperation of the sleeve 451 and the support rod 44, the angle of the blade portion 452 can be changed, thereby improving the flexibility of use of the scraper component 45.

[0049] In one embodiment, referring to Figure 1-Figure 3 The lower end dust removal component 4 also includes a placement seat 46, a guide rod 47 and a placement block 48. The placement seat 46 is arranged on the other side of the machine 1, and the guide rod 47 is arranged in the placement seat 46. The placement block 48 is movably arranged on the guide rod 47 and connected to the support rod 44. When the support rod 44 moves, since the other end of the support rod 44 is connected to the placement block 48 installed on the guide rod 47, it can play a supporting role when the support rod 44 moves, and through the cooperation of the guide rod 47, it plays a guiding role, thereby improving the stability of the support rod 44 when moving.

[0050] In one embodiment, referring to Figure 1 and Figure 2A cross bar 12 is also provided in the machine 1. The cross bar 12 is provided on the side of the pressure roller 23 away from the traction roller 22. A trimming component 13 is provided on the cross bar 12. The trimming component 13 can be used to cut the cast film to make the edge of the cast film neat, thereby improving the appearance quality of the product and facilitating subsequent packaging and logistics work.
