[0026] like Figures 1 to 3 As shown, the membrane tape dust removal mechanism 10 provided in this embodiment includes a first dust suction component 1, a second dust suction component 2, a filter box 3 and a first fan 4. The first dust suction component 1 is arranged on the side of the first surface of the membrane tape 101 and is used to suck out dust particles on the first surface. The first dust suction component 1 has a first dust inlet 11 and a first dust outlet (not shown in the figure); the second dust suction component 2 is arranged on the side of the second surface opposite to the first surface of the membrane tape 101 and is used to suck out dust particles on the second surface. The second dust suction component 2 has a second dust inlet 21 and a second dust outlet (not shown in the figure); the filter box 3 has a box body inlet and a box body outlet, and the box body inlet is respectively connected to the first dust outlet of the first dust suction component 1 and the second dust outlet of the second dust suction component 2; the first fan 4 is connected to the box body outlet of the filter box 3.

[0027] The above-mentioned membrane tape dust removal mechanism 10 adopts a first dust suction component 1 and a second dust suction component 2 to connect the filter box 3 and the first fan 4 respectively. The first dust suction component 1 is arranged on one side of the first side of the membrane tape 101, and the second dust suction component 2 is arranged on one side of the second side of the membrane tape 101. Negative pressure is formed by the first fan 4. The first dust suction component 1 and the second dust suction component 2 respectively adsorb and remove dust from the two sides of the cut membrane tape 101, and suck the dust into the filter box 3. In this way, the membrane tape dust removal mechanism 10 is used to clean the surface of the cut membrane tape 101, which can effectively reduce the particles on the surface of the membrane tape 101, avoid the phenomenon of uneven thickness of the membrane tape 101, improve the cleanliness of the membrane tape 101, and ensure the coating quality of the membrane tape 101.

[0028] See also Figures 1 to 3The membrane tape dust removal mechanism 10 provided in this embodiment includes a first dust suction component 1 and a second dust suction component 2. The shapes and sizes of the first dust suction component 1 and the second dust suction component 2 may be the same or different. In this embodiment, the shapes and sizes of the first dust suction component 1 and the second dust suction component 2 are the same. The first dust suction component 1 is used to suck out dust particles on the first surface. The first dust suction component 1 has a first adsorption chamber 12, a first dust inlet 11 and a first dust outlet. The first adsorption chamber 12 is respectively connected to the first dust inlet 11 and the first dust outlet. The first dust inlet 11 is arranged toward the first surface of the membrane tape 101. The second dust suction component 2 is used to suck out dust particles on the second surface. The second dust suction component 2 has a second adsorption chamber 22, a second dust inlet 21 and a second dust outlet. The second adsorption chamber 22 is respectively connected to the second dust inlet 21 and the second dust outlet, and the second dust inlet 21 is arranged toward the membrane tape 101.

[0029] Please continue to see Figures 1 to 3 The slurry layer (not shown) can be coated on the first surface or the second surface. In this embodiment, the first surface of the film tape 101 is the surface coated with the slurry layer, and the second surface is the blank surface. The first dust suction component 1 is arranged on the outside of the slurry-coated surface, and the second dust suction component 2 is arranged on the outside of the blank surface.

[0030] See also Figures 1 to 3 In this embodiment, the first dust suction component 1 and the second dust suction component 2 are arranged in sequence along the moving direction of the film tape 101 and are arranged alternately, that is, the first dust suction component 1 and the second dust suction component 2 are arranged in sequence after the film cutting process in the moving direction of the film tape 101.

[0031] In other embodiments, the second dust suction component 2 is arranged upstream of the first dust suction component 1 in the moving direction of the film strip 101.

[0032] See also Figures 1 to 3 In this embodiment, the first dust collecting component 1 is located below the second dust collecting component 2. The first dust inlet 11 of the first dust collecting component 1 is positioned upward, while the second dust inlet 21 of the second dust collecting component 2 is positioned downward. It is easy to understand that after the film cutting process, the slurry-coated side must be dusted first, followed by the blank side. Since the slurry-coated side faces downward, particles on the surface of the film strip 101 are first removed upward by the first dust collecting component 1, followed by particles removed downward by the second dust collecting component 2.

[0033] In other embodiments, when the side coated with the slurry faces upward, the first dust suction component 1 is arranged above the second dust suction component 2.

[0034] See also Figure 1 and Figure 2In this embodiment, the first dust collecting component 1 includes a hollow first shell 13, which is a tube body made of rigid material. The first shell 13 has, but is not limited to, a circular longitudinal cross-section. The first shell 13 has opposite open ends and closed ends, the open end forming a first dust outlet, the first shell 13 has a first protrusion 14 protruding outward from its surface, the first protrusion 14 extends along the axial direction of the first shell 13, and the first dust inlet 11 is located on the surface of the first protrusion 14; the second dust collecting component 2 includes a hollow second shell 23, which is a tube body made of rigid material. The second shell 23 has, but is not limited to, a circular longitudinal cross-section. The second shell 23 has opposite open ends and closed ends, the open end forming a second dust outlet, the second shell 23 has a second protrusion 24 protruding outward from its surface, the second protrusion 24 extends along the axial direction of the second shell 23, and the second dust inlet 21 is located on the surface of the second protrusion 24. In this way, by arranging the first dust inlet 11 on the first protrusion 14 and the second dust inlet 21 on the second protrusion 24 , the adsorption forces of the first dust inlet 11 and the second dust inlet 21 can be concentrated, thereby improving the adsorption cleaning effect.

[0035] See also Figure 1 and Figure 2 The membrane tape dust removal mechanism 10 provided in this embodiment further includes a first bracket 5 and a second bracket 6. The first dust suction component 1 is arranged on and supported by the first bracket 5, and the second dust suction component 2 is arranged on and supported by the second bracket 6. In this embodiment, the first bracket 5 includes a first horizontal plate 51, which is roughly horizontally arranged and located below the first dust suction component 1. The first horizontal plate 51 is arranged orthogonally to the first protrusion 14; the second bracket 6 includes a second horizontal plate 61, which is roughly horizontally arranged and located below the second dust suction component 2. The second horizontal plate 61 is arranged obliquely to the second protrusion 24. The angle between the second horizontal plate 61 and the second protrusion 24 is between 30 degrees and 45 degrees, preferably 45 degrees. In this way, by tilting the second horizontal plate 61 to the second protrusion 24, the maximum suction force and the best cleaning effect can be ensured.

[0036] See also Figure 1 and Figure 2 In this embodiment, both the first dust inlet 11 of the first dust collection component 1 and the second dust inlet 21 of the second dust collection component 2 are provided with a hollow collector 7. In this embodiment, the collector 7 includes a plurality of plates 71 connected end to end to form a collector 7 having, but not limited to, a rectangular cross-section. The plates 71 are made of, but not limited to, PMMA (Polymeric Methyl Methacrylate) plates.

[0037] See also Figure 1 and Figure 2 The filter box 3 provided in this embodiment has a box inlet and a box outlet. The box inlet is respectively connected to the first dust outlet of the first dust collection component 1 and the second dust outlet of the second dust collection component 2. In this embodiment, a filter assembly is arranged inside the filter box 3, which can filter the particles flowing into the box inlet and collect them inside the filter box 3. The filter box 3 is any existing filter box 3 in the prior art that can achieve the above functions.

[0038] See also Figure 1 and Figure 2 The first fan 4 provided in this embodiment includes an air inlet and an air outlet. The air inlet of the first fan 4 is connected to the box outlet of the filter box 3. It is easy to understand that through the operation of the first fan 4, a negative pressure is formed. In this way, an airflow is generated. The air flows into the filter box 3 from the first dust inlet 11 of the first dust suction component 1 and the second dust inlet 21 of the second dust suction component 2, and flows into the first fan 4 from the box outlet of the filter box 3.

[0039] See also Figure 1 and Figure 2 In this embodiment, the membrane belt dust removal mechanism 10 also includes a second fan 8. The air inlet of the second fan 8 is connected to the air outlet of the first fan 4, and the air outlet of the second fan 8 is connected to an external ventilation slot (not shown). The power of the second fan 8 is greater than that of the first fan 4. Thus, the use of the second fan 8 can increase the airflow, thereby improving the cleaning effect. It should be noted that the first dust collection component 1, the second dust collection component 2, the filter box 3, the first fan 4, and the second fan 8 provided in this embodiment are connected by a pipe unit, which is a rigid pipe body.

[0040] See also Figure 3 The film casting machine 100 provided in this embodiment includes a frame 102, a film cutting mechanism 103 supported on the frame, and a film strip dust removal mechanism 10. The film strip dust removal mechanism 10 is arranged downstream of the film cutting mechanism 103 along the movement direction of the film strip 101. In this embodiment, the frame 102 is provided with a guide roller 104 to guide the movement of the film strip 101. The first bracket 5 is fixedly mounted on the frame 102 by fasteners such as screws, thereby fixing the first dust collection component 1 to the frame 102. The second bracket 6 is fixedly mounted on the frame 102 by fasteners such as screws, thereby fixing the second dust collection component 2 to the frame 102.
