Description

Technical Field

[0001] This application relates to the field of cast film production equipment technology, and in particular to a cast film production equipment with a cleaning function. Background Technology

[0002] A casting machine is a plastic processing equipment used to produce cast film. Cast film is a thin film produced through the casting process, which has excellent physical and optical properties. After the production equipment has been running for a long time, some parts may wear out, producing metal shavings or other particles. It is also affected by environmental factors, which can cause dust to adhere to the cast film after production. Dust adhering to the surface of the cast film can cause defects on the film surface. For cast film products used in packaging, printing and other applications where high appearance quality is required, these appearance defects will reduce the product grade. Furthermore, the presence of dust may reduce the mechanical properties of the cast film, thereby reducing the quality of the cast film. Utility Model Content

[0042] Reference Figures 1-5 A casting film production apparatus with cleaning function includes a machine base 1, on which a roller assembly 2 is provided. The roller assembly 2 is used to squeeze and pull the casting film. The roller assembly 2 includes a pressure roller 21, a traction roller 22 and a take-up roller 23 distributed sequentially on the machine base 1. The traction roller 22 is located between the pressure roller 21 and the take-up roller 23. A cleaning assembly 3 is provided on the machine base 1 and is located between the pressure roller 21 and the traction roller 22. The cleaning assembly 3 is used to clean and cool the surface of the casting film. The cleaning assembly 3 includes a liquid storage tank 31 and a first push rod component 32. The liquid storage tank 31 is filled with cleaning liquid. The machine base 1 is provided with a first support plate 11 and is located above the liquid storage tank 31. The first push rod component 32 is provided on the first support plate 11. The piston end of the first push rod component 32 passes through the first support plate 11 and is equipped with a first roller component 321. The first roller component 321 is used to contact the casting film.

[0043] When the cast film is located between the liquid storage tank 31 and the first push rod component 32, the first roller component 321, with the cooperation of the first push rod component 32, embeds the cast film into the liquid storage tank 31. When the cast film is immersed in the liquid storage tank 31, the liquid in the liquid storage tank 31 can remove dust and impurities from the surface of the cast film and can also cool the cast film.

[0044] The machine 1 is also equipped with a dust collection component 4, which further removes dust from the cast film and can absorb water stains soaked in the liquid storage tank 31 on the cast film. The dust collection component 4 is located between the take-up roller 23 and the traction roller 22. The dust collection component 4 includes a dust collection box 41, which is connected to an external air pump. The external air pump can generate suction in the dust collection box 41. The machine 1 is also equipped with a second support plate 12, which is located above the dust collection box 41. A second push rod component 42 is provided on the second support plate 12. The piston end of the second push rod component 42 passes through the second support plate 12 and is equipped with a second roller component 421. An adhesive layer 4211 is provided on the outer periphery of the roller of the second roller component 421.

[0045] Based on the above structure, the extruded cast film, in cooperation with the roller assembly 2, will successively pass through the cleaning assembly 3 and the dust collection assembly 4, and finally be wound up by the take-up roller 23. When the cast film moves between the liquid storage tank 31 and the first roller 321 in the cleaning assembly 3 with the cooperation of the pressure roller 21, the first roller 321, in cooperation with the first push rod assembly 32, squeezes the cast film, thereby causing part of the cast film to embed into the liquid storage tank 31. Since the liquid storage tank 31 is filled with liquid, when the cast film is located in the liquid storage tank 31, the liquid will wash away the dust on the surface of the cast film and cool the cast film. Due to the flow of the cast film, the cast film passing through the cleaning assembly 3 will be wound up by the traction roller 22. The film moves towards the dust collection component 4. When the cast film is between the second roller 421 and the dust collection box 41, the dust collection box 41 generates suction under the action of an external air pump. The second roller 421, in cooperation with the second push rod component 42, moves the cast film towards the dust collection box 41. The dust collection box 41 further adsorbs the moisture and dust on the surface of the cast film. The adhesive layer 4211 on the second roller 421 can adhere the dust on the cast film. Finally, the film moves to the take-up roller 23 for winding. Through the cooperation of the cleaning component 3 and the dust collection component 4, the cast film can be cleaned with dual dust removal, solving the problem of dust adhering to the cast film during the production process and causing product quality damage.

[0046] Both the first push rod component 32 and the second push rod component 42 mentioned above adopt pneumatic or electric push rods in the prior art.

[0047] In one embodiment, reference is made to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The top of the machine 1 is also equipped with a scraper assembly 5. Since the cast film is in a high temperature state after it is extruded and formed, when the cast film first adheres to the pressure roller 21, some impurities will stick to the outer periphery of the pressure roller 21. During long-term use, impurities will be present on the outer periphery of the pressure roller 21, and in subsequent operations, the impurities will adhere to the surface of the cast film. Therefore, the scraper assembly 5 scrapes off the impurities on the outer periphery of the pressure roller 21. The scraper assembly 5 includes a support base 51, which is provided with two sets of spaced-apart support bases, and a shaft 52 is connected between the two sets of support bases 51.

[0048] A support frame 53 is movably mounted on the shaft 52. The support frame 53 has a sliding groove through which it passes. A support rod 54 is movably mounted on the sliding groove. A scraper seat 55 is mounted at the bottom of the support rod 54. The lateral position of the scraper seat 55 can be changed by moving the support frame 53 on the shaft 52.

[0049] By moving the support rod 54 on the chute, the tip of the scraper seat 55 can be brought closer to or away from the outer periphery of the pressure roller 21. By moving the support rod 54 in the chute, the vertical position of the scraper seat 55 can be changed, so that the scraper seat 55 can be used for cast films of different thicknesses and specifications, and the flexibility of the scraper assembly 5 can be improved.

[0050] The support rod 54 has several through holes 541, which are spaced apart along the length of the support rod 54. The through holes 541 can be arranged to accommodate different positions of the support rod 54. The support frame 53 has mounting holes 531 that pass through the slide groove. The diameter of the mounting hole 531 is the same as that of the through hole 541. When the mounting hole 531 is aligned with one of the through holes 541, a pin is connected between the mounting hole 531 and the through hole 541. The same diameter facilitates the passage of the pin. The support rod 54 is fixed to the support frame 53 by the pin. The pin passing through the mounting hole 531 and the through hole 541 can limit the position of the support rod 54, thereby preventing the pressure roller 21 from rotating during the operation of the scraper assembly 5, which would cause the scraper seat 55 to shake.

[0051] In one embodiment, reference is made to Figure 2 , Figure 3 and Figure 6 The machine base 1 has a recess 13, and a third push rod component 6 is provided in the recess 13. The third push rod component 6 is a pneumatic push rod or an electric push rod in the prior art. A bearing seat 61 is provided on the piston end of the third push rod component 6. The traction roller 22 is rotatably mounted on the bearing seat 61. With the cooperation of the third push rod component 6, the traction roller 22 can move relative to the length of the recess 13. Different cast film materials may require different tensions. Through the precise control of the third push rod component 6, the position of the traction roller 22 can be finely adjusted, thereby precisely controlling the tension attached to the cast film and thus adjusting the tension of the cast film.

[0052] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The dust collection box 41 has an arc-shaped end 411 on the side facing the second roller 421. With the cooperation of the second push rod component 42, the second roller 421 can drive the cast film to fit with the arc-shaped end 411. The design of the arc-shaped end 411 helps the cast film to fit more tightly on the second roller 421 during the bonding process. The arc-shaped end 411 can also guide the dust and impurities generated by the cast film during the movement to move into the dust collection box 41, which is convenient for collection and cleaning, and keeps the working environment clean.

[0053] In one embodiment, reference is made to Figures 1-3The machine 1 is also equipped with an ultrasonic generator 7. The bottom of the liquid storage tank 31 has a transducer 311 for connecting to the ultrasonic generator 7. The ultrasonic generator 7 is an ultrasonic generator in the prior art. The ultrasonic generator 7 can generate high-frequency vibrations, which are transmitted to the liquid in the liquid storage tank 31 through the transducer 311. When the ultrasonic waves propagate in the liquid, they will produce a cavitation effect, that is, the bubbles in the liquid will grow rapidly and collapse under the action of the ultrasonic waves, generating a strong impact force. When the cast film is located in the liquid storage tank 31, it can be cleaned.

[0054] In one embodiment, reference is made to Figures 1-3 The liquid storage tank 31 has slots 312 extending through the interior of the liquid storage tank 31 on both sides. The slots 312 have rounded ends. The rounded ends facilitate the flow of the cast film and disperse stress, making the film material transition smoothly, reducing the possibility of mechanical damage, avoiding wear on the surface of the cast film caused by the chamfer formed by the slots 312, and improving the smoothness of the cast film flow.

[0055] In one embodiment, reference is made to Figures 1-3 The machine 1 is also equipped with a control panel 14, which is electrically connected to the first push rod component 32, the second push rod component 42 and the third push rod component 6 respectively. The control panel 14 allows the operator to control different push rod components. By controlling the push rod components, the extension and retraction length of the push rod components can be adjusted, which is convenient for adjustment according to the different thicknesses of the cast film.
