Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0038] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] like Figure 1 , Figure 2 As shown, at least one embodiment provides a cleaning device for a coating blade head, comprising: a carrier plate 1, driven by a drive assembly 2 to move along the length of a coating blade head 10; a pair of blade assemblies 3, both disposed on the carrier plate 1 and located on either side of the coating blade head 10; a lifting assembly 4, disposed on the carrier plate 1 and located below the blade assemblies 3; a pressing assembly 5, used to press down the lifting assembly 4 to disengage the blade assemblies 3 from the coating blade head 10; and a control module electrically connected to the drive assembly 2, configured to control the drive assembly 2 to move the carrier plate 1 towards the coating blade head 10; wherein the lifting assembly 4 is adapted to move away from the pressing assembly 5 to raise the blade assemblies 3 until they are in close contact with the coating blade head 10.

[0040] Specifically, when cleaning is not required, the drive assembly 2 moves the carrier plate 1 to the outside of the end of the coating head 10. At this time, the pressing assembly 5 presses down the lifting assembly 4, so that the scraper assembly 3 does not adhere to the coating head 10.

[0041] Specifically, when cleaning is required, the drive assembly 2 moves the carrier plate 1 along the length of the coating head 10. At this time, the lifting assembly 4 moves away from the pressing assembly 5 and pushes the scraper assembly 3 upward, so that the scraper assembly 3 is in close contact with the side wall and bottom blade of the coating head 10, and then cleaning is performed by moving.

[0042] In this embodiment, a pair of scraper assemblies 3 are arranged on both sides of the coating head 10, so that one scraper assembly 3 corresponds only to the bottom blade surface and one side wall of the coating head 10, thereby improving the cleaning ability by better fitting the coating head 10.

[0043] like Figure 3 As shown, in some embodiments, the scraper assembly 3 includes: a base 31, at least one third guide rail 30 is provided on the base 31, a slot seat 32 is slidably provided on the third guide rail 30, and a scraper 33 is inserted in the slot seat 32; wherein, the lifting assembly 4 is adapted to drive each slot seat 32 to rise synchronously by moving away from the pressing assembly 5 so that the scraper 33 is in close contact with the coating head.

[0044] Specifically, the guide slot 32 of the third guide rail 30 moves vertically and is stopped by the limiting member on the third guide rail 30 as it falls.

[0045] In this embodiment, the lifting component 4 and the pressing component 5 work together to move the slot seat 32 up and down, thereby allowing the scraper assembly 3 to fit against or detach from the coating blade head 10.

[0046] like Figure 4 As shown, in some embodiments, the scraper 33 is approximately "L" shaped and includes: an inclined section 331 and a horizontal section 332; the inclined section 331 is inserted into the groove 32, and the horizontal section 332 protrudes from the groove 32; the inclined section 331 is arranged parallel to the side wall of the scraper 33; the horizontal section 332 is arranged parallel to the bottom blade surface of the scraper 33.

[0047] Specifically, the coating blade 10 includes a bottom blade surface and two sidewalls; wherein the bottom blade surface has a certain thickness and the two sidewalls have a certain inclination.

[0048] Optionally, the scraper 33 may be made of a slightly deformable material, such as rubber with a hardness of 60-80, to better fit the coating head 10.

[0049] In this embodiment, one scraper 33 can only correspond to the bottom blade surface and one side wall. Therefore, by providing scraper assemblies 3 on both sides of the coating head 10, the bottom blade surface and two side walls of the coating head 10 can be cleaned. At the same time, this separate design allows the scraper 33 to better fit the coating head 10.

[0050] In some embodiments, the scrapers 33 are staggered.

[0051] In this embodiment, the scrapers 33 on both sides are staggered to avoid collision between the horizontal sections 332 of the scrapers 33 on both sides.

[0052] like Figure 4As shown, in some embodiments, the slot 32 has a sliding groove 321 on one side that is adapted to the third guide rail 30 on the base 31, and an insertion groove 322 on the other side that is adapted to the scraper 33.

[0053] In this embodiment, the scraper 33 and the groove seat 32 adopt a straight-insertion structure to facilitate later maintenance and replacement.

[0054] like Figure 3 As shown, in some embodiments, a pair of first guide rails 11 are provided on the carrier plate 1; the base 31 of the scraper assembly 3 is slidably connected to the first guide rails 11; an electric gripper 6 is provided on the carrier plate 1, the electric gripper 6 is connected to the two bases 31, and the electric gripper 6 is electrically connected to the control module; wherein, the control module is configured to control the drive assembly 2 to make the carrier plate 1 drive the scraper mechanism 2 to move toward the coating head 10, and at the same time control the gripper assembly 3 to close the two bases 31 to the required distance.

[0055] Specifically, both bases 31 are slidably mounted on a pair of first guide rails 11, which are orthogonal to the length direction of the coating head 10, thereby guiding the carrier plate 1 to move toward the side wall of the coating head 10.

[0056] In this embodiment, the stroke of the electric gripper 6 is preset and can be adjusted according to different coating blades 10; when the base 31 is closed to the required spacing, the scraper assembly 3 can be made to fit the coating blade 10 by simply moving the groove seat 32 upward through the lifting assembly 4.

[0057] like Figure 2 As shown, in some embodiments, the lifting assembly 4 includes: a plurality of guide posts 41, vertically arranged on the carrier plate 1, and an elastic element 42 sleeved on them; a push plate 43, passing through the guide posts 41 and abutting against the elastic element 42; wherein, the push plate 43 is adapted to gradually lift the groove seat 32 by moving away from the pressing assembly 5 so that the scraper 33 is in close contact with the coating blade head.

[0058] Specifically, the elastic element 42 may be, but is not limited to, a spring; the push plate 43 is mounted on the spring. When the pressing assembly 5 presses down on the push plate 43, the spring is compressed to reduce the height of the push plate 43; as the push plate 43 moves away from the pressing assembly 5, the spring gradually pushes the push plate 43 upward to raise the slot seat 32.

[0059] like Figure 2 As shown, in some embodiments, the pressing assembly 5 includes: a fixing frame 51 and a pressing roller 52 disposed on the fixing frame 51; wherein the pressing roller 52 is adapted to press against the push plate 43 to lower the height of the slot seat 32.

[0060] like Figure 2As shown, in some embodiments, the push plate 43 has a guide slope 431 on the side facing the pressing roller 52; the push plate 43 is adapted to move the pressing roller 52 along the guide slope 431 by moving away from the pressing roller 52, that is, the push plate 43 gradually rises to push the slot seat 32.

[0061] Specifically, the guide slope 431 is lower as it gets closer to the edge of the push plate 43. That is, as the push plate 43 moves away from the pressing roller 52, the pressing roller 52 abuts against the guide slope 431, thereby causing the push plate 43 to gradually rise in height.

[0062] like Figure 1 As shown, in some embodiments, the drive assembly 2 includes: a driver 21 and a pair of second guide rails 22; both ends of the carrier plate 1 are respectively connected to the corresponding second guide rails 22; the driver 21 is disposed on the carrier plate 1 and is adapted to drive the carrier plate 1 to move along the second guide rails 22.

[0063] In this embodiment, the driver 21 can be a motor, the driving end of the motor is provided with a gear, and a rack is provided below the second guide rail 22 on the motor side. The carrier plate 1 moves along the second guide rail 22 through the cooperation of the gear and the rack.

[0064] like Figure 1 , Figure 3 As shown, in some embodiments, the cleaning device for the coating blade head further includes: a liquid bath 7; wherein two second guide rails 22 are respectively disposed on both sides of the liquid bath 7; a fixing frame 51 is connected to the liquid bath 7; at least one liquid mist nozzle 8 and at least one air blow nozzle 9 are disposed on the base 31; the liquid mist nozzle 8 is used to spray cleaning liquid onto the side wall of the coating blade head 10, and the air blow nozzle 9 is used to blow air onto the side wall of the coating blade head 10 to blow away most of the cleaning liquid.

[0065] Specifically, the function of the immersion tank 7 is to receive the cleaning fluid that falls from the coating blade 10.

[0066] In this embodiment, the working process of the liquid mist nozzle 8, the air blow nozzle 9, and the scraper 33 is as follows: first, the liquid mist nozzle 8 sprays cleaning fluid onto the coating blade head 10, then the air blow nozzle 9 blows away most of the cleaning fluid on the coating blade head 10, and finally the scraper 33 is pressed tightly against the coating blade head 10 to scrape off the remaining cleaning fluid.

[0067] At least one embodiment also provides a coating machine, including: a liquid bath 7; a coating head 10; and a cleaning device for the coating head; wherein two second guide rails 22 are respectively disposed on both sides of the liquid bath 7; and a fixing frame 51 is connected to the liquid bath 7.

[0068] For details regarding the specific structure and implementation process of the coating machine, please refer to the relevant discussions in the above embodiments, which will not be repeated here.

[0069] In summary, the cleaning device and coating machine for this coating head employ a pair of scraper assemblies 3 positioned on both sides of the coating head 10, so that each scraper assembly 3 corresponds only to the bottom blade surface and one side wall of the coating head 10, thereby improving cleaning capability through better contact with the coating head 10; at the same time, through the cooperation of the lifting assembly 4 and the pressing assembly 5, when the carrier plate 1 moves away from the pressing assembly 5, it drives the scraper assembly 3 to rise and closely contact the coating head 10.
