[0023] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0027] The dust removal module according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 2 As shown, the dust removal module according to an embodiment of the present invention includes a dust suction hood 10, a cutter 20, and an air blowing component 30.

[0029] Specifically, the dust suction port 11 of the dust suction hood 10 is provided with a mounting part 12 on the outside, and a cutter 20 is provided on the mounting part 12. The cutter 20 can cut the electrode film on the roller 50 on the first side of the mounting part 12. The air blowing member 30 is provided on the side of the cutter 20 away from the dust suction port 11, and the air blowing member 30 is located on the first side of the mounting part 12 to blow the waste material on the first side of the mounting part 12 to the dust suction port 11.

[0030] In other words, such as Figures 1 to 2 As shown, the cutting and dust removal module according to the present invention is mainly used in electrode production equipment. The cutting and dust removal module mainly includes a dust suction hood 10 and a cutter 20. The first end (e.g., the lower end) of the dust suction hood 10 is adapted to be connected to a vacuum cleaner. The second end (e.g., the upper end) of the dust suction hood 10 is provided with a dust suction port 11. The outer periphery of the dust suction port 11 is provided with a mounting portion 12. The mounting portion 12 can extend along the plane where the dust suction port 11 is located. The cutter 20 is mounted on the mounting portion 12, and at least a portion of the cutter 20 can be located on the first side (e.g., the upper side) of the mounting portion 12.

[0031] like Figures 1 to 2 As shown, during use, the roller 50 of the electrode production equipment is located on the first side of the mounting portion 12. The electrode film on the roller 50 can be cut on this side by the cutter 20, separating it into good films and waste (i.e., waste material). During the cutting process of the electrode film, some waste material will detach from the roller 50 and accumulate in the area where the cutter 20 is located due to its weak adhesion to the roller 50. Based on this, the dust removal module of this utility model embodiment is provided with an air blowing component 30 on the side of the cutter 20 away from the dust suction port 11. That is, the dust suction port 11, the cutter 20 and the air blowing component 30 are distributed sequentially along a first direction (e.g., the width direction of the dust suction port 11), and the air blowing component 30 is located on the first side of the mounting portion 12. Thus, the air blowing component 30 can blow air into the area where the cutter 20 is located on the first side of the mounting portion 12, thereby blowing the fallen waste material towards the dust suction port 11.

[0032] Therefore, according to the cutting and dust removal module provided in this embodiment, by using the air blowing component 30 provided on the side of the cutter 20 away from the dust suction port 11, the falling waste material can be blown towards the dust suction port 11, and the waste material that has detached from the roller 50 can be cleaned up in time, effectively avoiding the accumulation of waste material, ensuring the normal operation of the equipment, thereby effectively improving production efficiency, while reducing the maintenance frequency and cost of the equipment.

[0033] According to one embodiment of the present invention, the mounting part 12 is provided with a through groove adapted to the cutter 20, and the separate dust removal module further includes: a cutter seat 21, the cutter seat 21 is provided on the second side of the mounting part 12, the cutter 20 is provided on the cutter seat 21, and a portion of the cutter 20 extends through the through groove to the first side of the mounting part 12.

[0034] In other words, such as Figure 1As shown, the mounting portion 12 has a first side (e.g., upper side) and a second side (e.g., lower side) disposed opposite each other in its thickness direction. A cutter holder 21 is fixedly connected to the second side of the mounting portion 12, and a cutter 20 is mounted on the side of the cutter holder 21 near the mounting portion 12. At the same time, the mounting portion 12 is provided with a through groove that matches the size and position of the cutter 20, and a portion of the cutter 20 extends through the through groove to the first side of the mounting portion 12, thereby realizing the slitting operation of the electrode film on the first side of the mounting portion 12.

[0035] In this embodiment, the cutter 20 can be installed and fixed by the cutter holder 21. Moreover, the cutter holder 21 is set on the second side of the mounting part 12, so that the disassembly and assembly operations of the cutter holder 21 and the cutter 20 can be performed on the second side of the mounting part 12. This effectively avoids the interference of the roller 50 on the first side of the mounting part 12 on the disassembly and assembly process of the cutter holder 21 and the cutter 20, and improves the convenience of maintenance and replacement of the cutter 20.

[0036] In some specific embodiments of this utility model, the split dust removal module further includes: a first wall 13, which is located on the side of the dust suction port 11 away from the air blowing component 30, and the first wall 13 is connected to the dust suction hood 10.

[0037] like Figure 1 As shown, specifically, the suction port 11 has a first wall 13 connected to the suction hood 10 on the side away from the blowing element 30. The first wall 13 can be integrally formed with the suction hood 10. The first wall 13 can play a shielding role, which can effectively prevent waste from scattering, thereby improving the dust removal effect.

[0038] According to one embodiment of the present invention, the split-cut dust removal module further includes: a second wall 14, which is disposed at the first end of the first wall 13 along its length and is connected to the mounting portion 12; a third wall, which is disposed at the second end of the first wall 13 along its length and is connected to the mounting portion 12; the first wall 13, the second wall 14, the third wall, and the mounting portion 12 enclose a receiving space, which is suitable for a portion of the roller 50 to extend into.

[0039] In other words, such as Figure 1As shown, the first wall 13 has a first end and a second end arranged opposite to each other in its length direction. The first end of the first wall 13 is provided with a second wall 14, and the second end of the second wall 14 is provided with a third wall. The second wall 14 and the third wall extend toward the air blowing member 30, and the second wall 14 and the third wall are respectively connected to the mounting part 12, so that the first wall 13, the second wall 14 and the third wall surround the outer periphery of the dust suction port 11 and the mounting part 12 to form a roughly U-shaped shielding structure, which can effectively prevent waste from scattering, thereby improving the dust removal effect. Moreover, the first wall 13, the second wall 14, the third wall and the mounting part 12 enclose a receiving space, which is configured to allow part of the roller 50 to extend into, so that the cutter 20 can cut the electrode film within the receiving space, thereby further preventing waste from scattering and improving the dust removal effect.

[0040] In some optional embodiments of this utility model, the split-cutting dust module further includes: a scraper 40, which is disposed on the side of the cutter 20 away from the air blower 30, and at least a portion of the scraper 40 extends into the receiving space. The scraper 40 is adapted to fit against the roller 50 to peel off waste material from the roller 50.

[0041] Specifically, such as Figure 1 As shown, a scraper 40 is provided on the side of the cutter 20 away from the air blowing component 30. The scraper 40 can fit against the outer peripheral surface of the roller 50, thereby enabling the scraper 40 to peel off the waste material attached to the roller 50, thus ensuring the quality of the electrode film. In this example, the scraper 40 is fixedly connected to the outside of the receiving space. A portion of the scraper 40 can extend into the receiving space from the upper side of the first wall 13, that is, the gap between the first wall 13 and the roller 50, and fit against the portion of the roller 50 located in the receiving space. This allows the scraper 40 to peel off the waste material attached to the roller 50 within the receiving space. The peeled waste material can be collected through the dust suction port 11, effectively preventing waste material from scattering and improving the dust removal effect.

[0042] In some specific embodiments of this utility model, the split dust removal module further includes: an air blowing seat 31, which is located on the side of the mounting part 12 away from the first wall 13, and an air blowing component 30 is located on the side of the air blowing seat 31 close to the first wall 13.

[0043] That is to say, such as Figure 1 and Figure 2 As shown, an air blowing seat 31 is fixedly connected to the side of the mounting part 12 away from the first wall 13, and an air blowing component 30 is fixedly connected to the side of the air blowing seat 31 close to the first wall 13. The air blowing port of the air blowing component 30 can be arranged towards the location of the cutter 20, so that the air blowing component 30 can blow air into the area of ​​the cutter 20 on the first side of the mounting part 12, thereby blowing the fallen waste material towards the dust suction port 11.

[0044] In this embodiment, the air-blowing seat 31 provides an installation position for the air-blowing component 30, which is beneficial for the installation of the air-blowing component 30. Moreover, the air-blowing seat 31 can effectively block the opening on the side of the accommodating space near the air-blowing component 30, thereby effectively preventing waste from scattering and improving the dust removal effect.

[0045] According to one embodiment of the present invention, the air inlet of the air blowing component 30 is located on the side where the air blowing component 30 is connected to the air blowing seat 31, and the air blowing seat 31 is provided with a connecting hole 311 communicating with the air inlet. The connecting hole 311 is used to communicate with the fan.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the air blowing component 30 has an air blowing port and an air inlet, wherein the air blowing port is located on the first side of the air blowing component 30 and is used to blow air into the area where the cutter 20 is located. The first side of the air blowing component 30 is fixedly connected to the air blowing base 31, and the air blowing base 31 is provided with a connection hole 311 corresponding to the air inlet of the air blowing component 30. The first end of the connection hole 311 communicates with the air inlet of the air blowing component 30, and the second end of the connection hole 311 communicates with a fan, so that the fan can provide airflow to the air blowing port of the air blowing component 30, enabling the air blowing port to blow air into the area where the cutter 20 is located on the first side of the mounting part 12.

[0047] In this embodiment, the air inlet of the air blowing component 30 is connected to the blower through the connection hole 311 on the air blowing seat 31, which can effectively simplify the air supply pipeline of the air blowing component 30.

[0048] In some specific embodiments of this utility model, the slitting and dust removal module includes multiple cutters 20, and the air blowing component 30 is adapted to blow the waste generated by the multiple cutters 20 to the dust suction port 11.

[0049] In other words, such as Figure 1 and Figure 2 As shown, the mounting part 12 is provided with multiple cutters 20, which can be arranged along the length direction of the dust collection port 11 (i.e., the axial direction of the roller 50). In this embodiment, there are two cutters 20, which can cut off the waste edges on both sides of the electrode film. The air blowing port of the air blowing member 30 extends from the location of the first waste edge to the location of the second waste edge along the length direction of the dust collection port 11, so that the air blowing member 30 can blow the waste generated by the multiple cutters 20 to the dust collection port 11, thereby eliminating the need to provide multiple air blowing members 30 and simplifying the overall structure of the dust removal module.

[0050] In summary, according to the cutting and dust removal module provided in this embodiment, the air blowing component 30 provided on the side of the cutter 20 away from the dust suction port 11 can blow the falling waste material toward the dust suction port 11, clean up the waste material that has detached from the roller 50 in a timely manner, effectively avoid the accumulation of waste material, ensure the normal operation of the equipment, thereby effectively improving production efficiency and reducing the frequency and cost of equipment maintenance.

[0051] like Figure 1 and Figure 2 As shown, an embodiment of the present invention also provides an electrode production apparatus, which is a dry electrode production apparatus. This apparatus includes a dust removal module as described in any of the above embodiments; a roller 50 configured to rotatable about its own axial direction, and the roller 50 is located on the first side of the mounting portion 12. Since the dust removal module according to the embodiments of the present invention has the above-mentioned technical effects, the electrode production apparatus according to the embodiments of the present invention also has corresponding technical effects, which will not be elaborated further in this embodiment.

[0052] According to one embodiment of the present invention, the electrode production equipment further includes: a bearing seat 60, on which the roller 50 is rotatably disposed about its own axis; and a fixing member 70, which is connected to the bearing seat 60 and the dust removal module respectively.

[0053] In other words, such as Figure 1 and Figure 2 As shown, the electrode production equipment according to an embodiment of this utility model mainly includes a machine body, rollers 50, and a dust removal module. The machine body is provided with bearing seats 60 suitable for mounting the rollers 50. There can be two bearing seats 60. The first end of the roller 50 is rotatably mounted on the first bearing seat 60 around its own axis, and the second end of the roller 50 is rotatably mounted on the second bearing seat 60 around its own axis. The dust removal module is fixedly connected to the two bearing seats 60 by fixing members 70. For example, the dust suction hood 10, the air blowing seat 31, and the scraper 40 are all connected to the fixing members 70, which are fixedly connected to the bearing seats 60, thus connecting the dust removal module to the bearing seats 60. Therefore, when adjusting the roller gap between the two rollers 50, the dust removal module moves together with the rollers and bearing seats, ensuring that the relative position of the dust removal module to the rollers 50 does not shift with changes in the roller gap.
