Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of battery electrode production equipment, and in particular to a die lip cleaning mechanism for a coating die head. Background Technology
[0002] Electrode sheets are a crucial component of batteries, primarily manufactured through processes such as coating, rolling, and slitting. Coating of lithium battery electrode materials, such as non-contact coating, can only be performed with a back roller. In some cases, such as space constraints or when the other side is already coated with slurry and a back roller cannot be installed, non-contact coating is not feasible. Contact coating mechanisms use a two-sided die head with a contact curtain-type fixed-gap coating, directly contacting the foil material. When the machine stops, the slurry at the die lip can easily dry out, requiring manual wiping of the die lip to remove the dry material and ensure coating quality.
[0003] The applicant's earlier Chinese patent application CN202323522571.5 discloses an extrusion coating head, including a first mold, a second mold, and a clamping piece sandwiched between the first and second molds to form a coating gap. The front end of the coating gap has a coating nozzle, which includes a bottom extension of the first mold and a bottom extension of the second mold. The outer surface of the bottom extension of the first mold is arc-shaped. The first end of the bottom extension of the first mold extends in the direction of travel of the substrate to form a horizontal portion parallel to the direction of travel of the substrate. The end of the bottom extension of the first mold extends upward to form a vertical portion connected to the lower surface of the first mold. This invention has the advantages of better anti-vibration effect, ability to limit the coating, and controllable coating thickness. This application is based on and further improves upon this design.
[0004] This invention overcomes the shortcomings of the prior art by providing a die lip cleaning mechanism for a coating die head, which can replace manual cleaning and achieve automated cleaning of the die lip of the coating die head. Utility Model Content

The lateral moving component is connected to the coating die head via the adapter plate. The moving range of the lateral moving component covers the length of the die lip of the coating die head. The telescopic component is located on the lateral moving component. The lateral moving component drives the telescopic component to move along the die lip direction of the coating die head. The telescopic component is connected to the cleaning section. The telescopic component drives the cleaning section to approach the die lip and contact the die lip.
[0007] Optionally, the telescopic assembly includes a cylinder and a guide rod. The cylinder is connected to the lateral movement assembly via a slider, and the cylinder is connected to the guide rod, which is connected to the cleaning section.
[0008] Optionally, the cleaning part has a recessed contact surface at a predetermined angle, the contact surface being used to contact the mold lip, and the bottom of the contact surface is provided with an arc-shaped groove.
[0009] Optionally, the bottom of the arc-shaped groove is provided with a vertically arranged plug, which is used to clean the inner side of the mold lip.
[0010] Optionally, there are multiple telescopic components, which are disposed on the same transverse component. Each telescopic component is connected to a cleaning part, and at least one cleaning part is provided with the plug.
[0011] Optionally, a receiving box is provided below the cleaning section, and the width of the receiving box is greater than the width of the cleaning section.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] like Figure 1-7 The diagram shown is a schematic representation of an embodiment of the die lip cleaning mechanism for the coating die head provided by this utility model.
[0032] Please refer to Figure 1-7 This embodiment is used to clean the die lip of the coating die head, and includes a coating die head 10 and a cleaning mechanism 20. The cleaning mechanism 20 is connected to the coating die head 10 through an adapter plate 21.
[0033] The cleaning mechanism 20 includes a transverse component 22, a telescopic component 23, and a cleaning section 24. The transverse component 22 is connected to the coating die head 10 via an adapter plate 21. The moving range of the transverse component 22 covers the length of the die lip 11 of the coating die head 10. The telescopic component 23 is located on the transverse component 22. The transverse component 22 drives the telescopic component 23 to move along the direction of the die lip 11 of the coating die head 10. The telescopic component 23 is connected to the cleaning section 24. The telescopic component 23 drives the cleaning section 24 to approach the die lip 11 and contact the die lip 11.
[0034] The cleaning mechanism 20 and the coating die 10 are arranged in parallel with a certain distance between them to avoid the cleaning mechanism 20 affecting or interfering with the coating die 10 during operation. When the coating die 10 stops, the telescopic component 23 moves the cleaning part 24 closer to the die lip 11. After the cleaning part 24 contacts the die lip 11, the lateral component 22 moves the telescopic component 23 and the cleaning part 24 laterally to achieve overall cleaning of the die lip. After cleaning, the telescopic component 23 moves the cleaning part 24 away from the die lip 11 so that the coating die 10 can continue to work. The cleaning mechanism 20 provided in this embodiment is applicable to cleaning coating dies 10 including double-sided dies and single-sided dies.
[0035] In one embodiment, the telescopic component 23 includes a cylinder 231 and a guide rod 232. The cylinder 231 is connected to the transverse component 22 via a slider 233, and the cylinder 231 is also connected to the guide rod 232. The guide rod 232 is connected to the cleaning part 24. By extending the guide rod 232 through the cylinder 231, the cleaning part 24 is moved closer to or away from the coating die head 10. Specifically, the transverse component 22 can be a linear module.
[0036] In one embodiment, the cleaning part 24 has a concave contact surface 241 at a predetermined angle. The contact surface 241 is used to contact the mold lip 11. The bottom of the contact surface 241 is provided with an arc-shaped groove 242. The concave contact surface 241 and the arc-shaped groove 242 cover both sides of the mold lip 11, increasing the contact area and cleaning area.
[0037] Furthermore, the bottom of the arc-shaped groove 242 is provided with a vertically arranged plug 243, which is used to clean the inner side of the mold lip 11. The transverse component 22 drives the plug 243 from the side of the mold lip 11 into the inner side of the mold lip 11. When the plug 243 moves inside the mold lip 11, it scrapes away and cleans the dry material inside the mold lip 11.
[0038] Specifically, there are multiple telescopic components 23, which are disposed on the same transverse component 22. Each telescopic component 23 is connected to a cleaning section 24, and at least one cleaning section 24 is provided with a plug 243. In this embodiment, there are two telescopic components 23, which are disposed on the same transverse component 22. Each telescopic component 23 is connected to a cleaning section 24, one of which is provided with a plug 243, and the other is not provided with a plug 243. The cleaning section 24 with the plug 243 is suitable for cleaning the inner side and surface of the die lip 11 when the coating die head 10 is stopped for a long time, while the cleaning section 24 without the plug 243 is suitable for cleaning the surface of the die lip 11 when the coating die head 10 is stopped for a short time.
[0039] In one embodiment, a receiving box 244 is provided below the cleaning section 24. The width of the receiving box 244 is greater than the width of the cleaning section 24. The cleaning section 24 is located in the upper middle part of the receiving box 244. The receiving box 244 is used to collect cleaning waste. The waste scraped and cleaned by the cleaning section 24 falls into the receiving box 244.
[0040] Specifically, the cleaning section 24 is made of sponge material, but other flexible materials can also be used. It will not damage the mold lip 11 during the wiping and cleaning process, while also achieving a cleaning effect. The cleaning section 24 is specifically connected to the telescopic component 23 through an L-shaped bracket 245. The vertical part of the L-shaped bracket 245 is connected to the telescopic component 23, and the lower side of the horizontal part of the L-shaped bracket 245 is connected to the receiving box 244.
[0041] In one embodiment, the coating die head 10 includes an upper die 12 and a lower die 13. The bottom of the upper die 12 and the bottom of the lower die 13 form a die lip 11 with a height difference. The gap between the upper die 12 and the lower die 13 is a material conveying channel. The material conveying channel is connected to the die lip 11. The die lip 11 is used to discharge material for coating onto the surface of the foil.
[0042] Furthermore, including a rotating assembly 30, the coating die head 10 is connected to the frame 14 via the rotating assembly 30. The rotating assembly 30 drives the coating die head 10 to rotate, adjusting the gap between the die lip 11 and the foil 50. Specifically, the rotating assembly 30 can be a rotary cutter drive motor. The die lip 11 is used to discharge material and coat it onto the surface of the foil 50. During coating, the bottom of the lower die 13 abuts against the foil. The rotating assembly 30 drives the coating die head 10 to rotate, adjusting the distance between the bottom of the upper die 12 and the foil 50. In addition, the rotating assembly 30 rotates the coating die head 10 by a certain angle so that the die lip 11 faces the cleaning mechanism 20, making it easier for the cleaning mechanism 20 to clean the die lip 11 better.
[0043] Furthermore, the frame 14 is connected to the lifting guide rail 16 via a movable plate 15. The movable plate 15 is connected to the lifting drive component 40, which drives the movable plate 15 to move up and down along the lifting guide rail 16. The lifting drive component 40 raises the coating die head 10, expanding the space below the coating die head and facilitating cleaning by the cleaning mechanism 20. Specifically, the lifting drive component 40 can be a lifting electric cylinder.
[0044] In this embodiment, the coating die head 10 is used to achieve material coating of foil. Its specific structure can be referred to the applicant's prior patent application 202323522571.5, and the relevant description will not be repeated.
[0045] The working process of the mold lip cleaning mechanism in this embodiment of the utility model is as follows:
[0046] 1. For example Figure 6 As shown, when the coating die 10 stops, the lifting drive 40 drives the coating die 10 to rise from the coating position to the stopping position. The cleaning mechanism 20 first pushes the cleaning part 24 to the cleaning position via the cylinder 231, and then the coating die 10 descends from the stopping position to contact the cleaning part 24 and reach the cleaning position. Then, the horizontal movement component 22 moves horizontally left and right to perform the wiping and cleaning function.
[0047] 2. For example Figure 7 As shown, when the coating die 10 stops, the coating die 10 is rotated from the coating position to the stopping position by the rotating component 30. The cleaning mechanism 20 first pushes the cleaning part 24 to the cleaning position by the cylinder 231. Then, it moves left and right by the transverse component 22 to wipe and clean.
[0048] There are two types of cleaning sections 24: one with a plug 243 and one without. The cleaning section 24 without the plug 243 cleans the surface of the lip separately and is suitable for short-term cleaning of the coating die 10 during downtime. The cleaning section 24 with the plug 243 is responsible for cleaning the inside of the die lip 11 and is suitable for cleaning of the coating die 10 during long-term downtime.
[0049] In summary, the embodiments provided by this utility model use a telescopic component to bring the cleaning part closer to the die lip. After the cleaning part contacts the die lip, the telescopic component and the cleaning part move laterally through a lateral movement component, thereby achieving automated cleaning and wiping of the die lip. This solves the problem that the middle part of the coating die head cannot be manually cleaned during wide-width coating. Furthermore, the telescopic component can move the cleaning part away from the die lip, avoiding affecting the coating process of the coating die head.

Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
