[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0036] For this purpose, please refer to Figures 1 to 5This embodiment provides a film-forming and laminating integrated machine with a dust removal component, including: a frame 1; a pressure roller mechanism, including a first drive component and multiple pressure rollers 2, the multiple pressure rollers 2 are arranged in parallel, and a gap is formed between each two adjacent pressure rollers 2 for the film to pass through; the pressure rollers 2 are rotatably connected to the frame 1, and each pressure roller 2 is driven to rotate by a set of first drive components; a dust removal component 3, including a scraper 301 and a negative pressure chamber 302, the negative pressure chamber 302 is connected to an external vacuum device; the negative pressure chamber 302 is rotatably connected to the frame 1; the scraper 301 is disposed on the negative pressure chamber 302 and abuts against the pressure roller 2, for scraping off waste material on the pressure roller 2; an adsorption port 303 communicating with its inner cavity is provided on one side of the scraper 301 on the negative pressure chamber 302; each pressure roller 2 is provided with a set of dust removal components 3.

[0037] It should be noted that multiple pressure rollers 2 are arranged at intervals along the first direction, and the diaphragm is alternately wound around the multiple pressure rollers 2 along the first direction.

[0038] In this embodiment, during operation, the film is squeezed through the gap between two adjacent pressure rollers 2 and alternately wound around multiple pressure rollers 2. The pressure rollers 2 are driven to rotate by the first driving component, and adjacent pressure rollers 2 rotate synchronously but in opposite directions to facilitate film conveying. During the rotation of the pressure rollers 2, the scraper 301 of the dust removal component 3 abuts against the pressure rollers 2, so that the scraper 301 effectively scrapes off the waste material remaining on the pressure rollers 2, ensuring that the roller surface of the pressure rollers 2 always remains clean and flat, improving the production quality of lithium battery films and reducing the film defects caused by unclean pressure roller surfaces. Problems such as uneven sheet thickness and surface defects are eliminated, reducing the defect rate, increasing the yield rate, saving production costs, and enhancing the market competitiveness of the products. At the same time, the scraped waste is adsorbed by the adsorption port 303 and transported to the negative pressure chamber 302 for external collection, preventing the scraped waste from flying around in the workshop and polluting the external environment, protecting the health of operators, and preventing waste from accidentally falling into the critical components inside the equipment. This reduces equipment failures caused by waste clogging or wearing parts, extends the service life of the equipment, and further reduces equipment maintenance and replacement costs.

[0039] Specifically, the first drive assembly includes a first drive motor, the output end of which is driven to the pressure roller 2 to drive the pressure roller 2 to rotate.

[0040] Specifically, the scraper 301 is arranged parallel to the pressure roller 2 to ensure that the scraper 301 is evenly attached to the pressure roller 2, thereby ensuring the scraping effect.

[0041] In one embodiment, such as Figure 4 As shown, both ends of the negative pressure chamber 302 are rotatably connected to the frame 1 via adjustment components.

[0042] In this embodiment, the negative pressure chamber 302 is rotatably mounted on the frame 1 via an adjustment component, so that the negative pressure chamber 302 can be rotated to adjust the angle of the scraper 301. The operator can flexibly adjust the angle between the scraper 301 and the pressure roller 2 according to the surface condition of the pressure roller 2, so that the scraper 301 can contact the pressure roller 2 at the optimal angle, thereby achieving the best cleaning effect.

[0043] In one embodiment, such as Figure 4 As shown, the adjustment assembly includes a fixed base 4, a locking block 5, and a fastener. The locking block 5 is connected to the frame 1 via the fixed base 4. The locking block 5 has a connecting hole along a direction parallel to the axial direction of the pressure roller 2, and the circumference of the locking block 5 has an opening 6 communicating with the connecting hole. The opening 6 divides the locking block 5 into a first adjustment part 7 and a second adjustment part 8. The fastener passes through the first adjustment part 7 corresponding to the opening 6 and is threadedly connected to the second adjustment part 8 to adjust the size of the opening 6. The end of the negative pressure chamber 302 is rotatably inserted into the connecting hole via a rotating shaft 9.

[0044] In this embodiment, when it is necessary to adjust the angle of the scraper 301, the negative pressure chamber 302 is manually adjusted. The negative pressure chamber 302 rotates in the connecting hole via the rotating shaft 9. When it rotates to the optimal angle, the space of the opening 6 is reduced by tightening the fastener, thereby making the space of the connecting hole smaller and locking the rotating shaft 9 in place. Conversely, when adjustment is needed, the fastener is loosened, making the space of the opening 6 larger and the space of the connecting hole loose, so that the rotating shaft 9 can rotate in the connecting hole to facilitate angle adjustment.

[0045] Specifically, the fastener is the first screw.

[0046] In one embodiment, such as Figure 4 As shown, the dust removal assembly 3 also includes a pressure plate 304, which is detachably connected to the negative pressure chamber 302; a scraper 301 is sandwiched between the pressure plate 304 and the negative pressure chamber 302.

[0047] In this embodiment, the scraper 301 is clamped onto the negative pressure cavity 302 by the pressure plate 304, which facilitates installation and disassembly. The extension length of the scraper 301 can be adjusted according to actual needs, further improving the flexibility of adjustment and enhancing the cleaning effect. This ensures that the best cleaning effect can be achieved through adjustment under any production conditions, enabling comprehensive and efficient cleaning of the pressure roller 2 and further guaranteeing the stability of the film production quality.

[0048] Specifically, such as Figure 4 As shown, the pressure plate 304 is connected to the negative pressure chamber 302 by the second screw, which facilitates installation and disassembly.

[0049] In one embodiment, such as Figure 4As shown, the orientation of the scraper 301 is opposite to the rotation direction of the pressure roller 2, and the suction port 303 is located on the side of the scraper 301 away from the pressure roller 2.

[0050] In this embodiment, by setting the orientation of the scraper 301 to be opposite to the rotation direction of the pressure roller 2 to form a preset angle, it is convenient to use the force during the rotation of the pressure roller 2 to ensure that the material on the pressure roller 2 can be scraped off, thereby improving the cleaning effect. In addition, the suction port 303 is located on the side of the scraper 301 away from the pressure roller 2, so that the scraped waste can be absorbed and processed in time, further improving the cleaning effect.

[0051] In one embodiment, the scraper 301 is made of PEEK material.

[0052] In this embodiment, the scraper 301 is made of PEEK material, which is elastic and wear-resistant, so that the scraper 301 can closely adhere to the surface of the pressure roller 2, and can even press on the roller surface of the pressure roller 2 as needed. Compared with traditional cleaning methods, it can more effectively remove the waste material adhering to the pressure roller 2, ensuring that the surface of the pressure roller 2 always remains clean and flat.

[0053] In one embodiment, such as Figure 3 and Figure 5 As shown, the film-forming and laminating machine with dust removal components also includes a waste collection component, which is set on the frame 1 and located below multiple pressure rollers 2, for collecting waste materials falling from the pressure rollers 2.

[0054] In this embodiment, by setting up a waste collection component below multiple pressure rollers 2, the waste falling from the pressure rollers 2 is collected in real time. Compared with the traditional manual timed cleaning method, the efficiency of waste collection is greatly improved, the workload of manual cleaning is reduced, and the labor cost is lowered.

[0055] In one embodiment, such as Figure 3 and Figure 5 As shown, the waste collection assembly includes a conveyor belt 10, a second drive assembly, and a collection box 11; the conveyor belt 10 is rotatably mounted on the frame 1 and is driven to rotate by the second drive assembly; the projections of multiple pressure rollers 2 in the vertical direction all fall on the conveyor belt 10; the collection box 11 is mounted on the frame 1 and located at the end of the conveyor belt 10, and is used to collect the waste conveyed by the conveyor belt 10.

[0056] In this embodiment, by setting a conveyor belt 10 below multiple pressure rollers 2 and setting a collection box 11 at the end of the conveyor belt 10 in the conveying direction, the waste material falling off the pressure rollers 2 during operation falls onto the conveyor belt 10 and is then conveyed by the conveyor belt 10 to the collection box 11 at the end, collecting the waste material falling off the pressure rollers 2 in real time. Compared with the traditional manual timed cleaning method, this greatly improves the efficiency of waste collection, reduces the workload of manual cleaning, and lowers labor costs.

[0057] Specifically, the second drive assembly includes a second drive motor and a plurality of spaced-apart conveyor wheels. The conveyor belt 10 is wound around the plurality of conveyor wheels and is driven to rotate by the second drive motor, thereby driving the conveyor belt 10 to rotate.

[0058] Specifically, the conveyor belt 10 is made of antistatic rubber to prevent waste from sticking to the conveyor belt 10 and improve the cleaning effect.

[0059] In one embodiment, such as Figure 3 and Figure 5 As shown, the waste collection assembly also includes a guide plate 12; the guide plate 12 is mounted on the frame 1; one end of the guide plate 12 is attached to the conveyor belt 10, and the other end is inclined toward the collection box 11, for guiding the waste on the conveyor belt 10 to the collection box 11.

[0060] In this embodiment, a guide plate 12 is provided between the end of the conveyor belt 10 and the collection box 11 to guide the waste to the collection box 11, ensuring that the waste can be collected smoothly and avoiding accidental falling and accumulation of waste during the conveying process, thus ensuring the smoothness and stability of the waste collection process.

[0061] In one embodiment, such as Figure 3 and Figure 6 As shown, each dust removal component 3 is located downstream of the separation point between the pressure roller 2 and the diaphragm.

[0062] In this embodiment, the dust removal component 3 is located downstream of the separation point between the pressure roller 2 and the diaphragm, so as to remove the waste material on the pressure roller 2 in a timely manner, ensure the cleanliness and flatness of the pressure roller 2, improve the cleaning effect, and thus improve the production quality of the diaphragm.

[0063] In one embodiment, such as Figure 3 As shown, there are six pressure rollers 2.

[0064] In this embodiment, six pressure rollers 2 are provided to ensure the production quality of the film.

[0065] Specifically, the film-forming and laminating integrated machine with dust removal components also includes a winding and unwinding machine 13. The winding and unwinding machine 13 includes a winding component and an unwinding component. The unwinding component unwinds the film to be processed by multiple pressure rollers 2, and then the winding component rewinds and recycles the processed film.

[0066] Specifically, the negative pressure chamber 302 has a pipe interface for communicating with its inner cavity. The pipe interface is connected to an external vacuum device via a flexible hose. The external vacuum device can be a negative pressure fan.

[0067] The specific working principle of the film-forming and laminating integrated machine with dust removal component provided in this embodiment is as follows: The film is unwound by the unwinding component, squeezed through the gap between two adjacent pressure rollers 2, and alternately wound around multiple pressure rollers 2 in sequence, before returning to the winding component for winding. The pressure rollers 2 can be driven to rotate by the first driving component, and two adjacent pressure rollers 2 rotate synchronously but in opposite directions to facilitate film conveying. During the rotation of the pressure rollers 2, the scraper 301 of the dust removal component 3 abuts against the pressure rollers 2, scraping off the waste material on the pressure rollers 2. At the same time, the scraped waste material is adsorbed and collected by the adsorption port 303 of the negative pressure chamber 302. During the operation, the film can be adjusted in real time according to the dust removal component. Specifically, by adjusting the components and the pressure plate 304, the angle of the scraper 301 and the length extending out of the negative pressure chamber 302 can be flexibly adjusted to ensure the best cleaning effect. At the same time, the fallen waste material falls onto the conveyor belt 10 and is conveyed by the conveyor belt 10 through the guide plate 12 to the collection box 11, which improves the cleaning effect and solves the technical problem that in the existing film forming and laminating machine, after the film is squeezed by the pressure roller 2, the material adheres to the surface of the pressure roller 2, affecting the flatness of the surface of the pressure roller 2, resulting in uneven thickness and rough surface of the film that passes through the pressure roller 2, which affects the product quality of lithium battery film.

[0068] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
