[0061] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0062] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0063] As the impact of energy shortage and greenhouse effect becomes more and more serious, new energy technologies have emerged. Among new energy technologies, lithium-ion batteries have developed rapidly. They can not only be used as energy storage materials but also provide power for automobiles and the like. In the production process of lithium-ion batteries, the coating process is a crucial step. The most widely used battery coating technology for power batteries is slit extrusion coating. As a precise wet coating technology, slit extrusion coating works by squeezing the coating slurry along the die lip of the die under a certain pressure and a certain flow rate and transferring it to the substrate wound on the main roller. After the coating is completed, the wet coating slurry is likely to remain on the die lip. Over time, the coating slurry will clog the outlet of the die lip after solidification, affecting subsequent coating. Therefore, the die lip needs to be cleaned at the beginning of coating and when the machine is stopped and restarted during coating to ensure the normal coating. The existing operation of cleaning the die lip is generally to manually wipe it repeatedly with dust-free paper until there is no dry material on the die lip. However, this method has the following problems:

[0064] First, if the operator does not wipe it in time, the slurry will overflow, causing more slurry to accumulate at the die lip and contaminate the main roller and substrate;

[0065] Second, there is a risk of your hands being caught by the main roller and the die head during manual wiping.

[0066] In response to the above problems, the present application provides a die lip cleaning device that can automatically clean the die lip when the die is not working, thereby ensuring the normal operation and coating effect of the coating. The structure of the die lip cleaning device provided by the present application is described below.

[0067] like Figure 1 As shown, Figure 1 This is a schematic structural diagram of a die lip cleaning device 10 provided in this application, which consists of Figure 1 It can be seen that the die lip cleaning device 10 includes a cleaning mechanism 100 and a material storage mechanism 200 .

[0068] Among them, Figure 2 As shown, the cleaning mechanism 100 includes a suction assembly 110 and a first driving assembly 120 .

[0069] The adsorption component 110 is used to move to the target position under the drive of the first drive component 120; the adsorption component 110 can also be used to adsorb the cleaning sheet from the storage frame 220 of the storage mechanism 200; the adsorption component 110 is also used to move back and forth relative to the die head lip 4011 under the drive of the first drive component 120.

[0070] The adsorption component 110 can move in a manner such as translation, lifting, rotation, etc. driven by the first driving component 120, and the specific configuration is based on the required configuration and is not limited here.

[0071] The adsorption component 110 may adsorb the cleaning sheet by means of a structure with adsorption function provided thereon; or it may adsorb the cleaning sheet by changing the air pressure in its cavity; the adsorption component 110 may also adsorb the cleaning sheet by means of a picking-up structure provided thereon, etc. This application does not impose any limitation on this.

[0072] The first drive component 120 can, for example, realize the movement of the adsorption component 110 through the cooperation of a motor and a screw rod; it can also realize the movement of the adsorption component 110 through the cooperation of a motor and a belt 12112; it can also realize the movement of the adsorption component 110 through the cooperation of a cylinder 2302 and a telescopic structure; it can also realize the movement of the adsorption component 110 through the cooperation of a motor and a pulley, and this application does not limit this.

[0073] In an optional embodiment, if Figure 3 As shown, the adsorption assembly 110 includes a suction and release component 111 and an air pressure control component 112 .

[0074] The suction and placement member 111 is connected to the air pressure control member 112 , which is used to control the air pressure in the cavity of the suction and placement member 111 so as to absorb the cleaning sheet from the storage frame 220 through the air pressure in the cavity of the suction and placement member 111 .

[0075] The suction and release member 111 can be a structure having a cavity, equivalent to a gas inlet and outlet. Exemplarily, the suction and release member 111 is funnel-shaped or trumpet-shaped. Since the suction and release member 111 is used to clean the die lip 4011 in conjunction with the cleaning sheet, in order to avoid damaging the die lip 4011, the suction and release member 111 can be made of a relatively soft material. Exemplarily, the material of the suction and release member 111 is, for example, silicone.

[0076] The air pressure control component 112 sucks out the air in the cavity of the suction and release component 111, so that the gas in the cavity of the suction and release component 111 presents a negative pressure, thereby being able to adsorb objects in front of the suction and release component 111 into the cavity of the suction and release component 111; it is understood that the air pressure control component 112 can also blow air into the cavity of the suction and release component 111 to make the gas in the cavity of the suction and release component 111 present a positive pressure, thereby being able to release the objects adsorbed by the suction and release component 111 from the cavity. Exemplarily, the air pressure control component 112 is a high-pressure suction and blower, a vortex suction and blower, etc.

[0077] In another embodiment, in order to better control the air pressure in the cavity of the suction and release member 111, the suction and release member 111 may include a first surface and a second surface that are arranged opposite to each other. If the suction and release member 111 is a funnel-shaped structure made of silicone, that is, the sidewalls of the funnel-shaped structure are made of double-layer material, and the two layers of silicone material are only connected at the edges, so that a cavity is formed between the two layers of silicone material. In addition, if Figure 4 As shown, the present application may be provided with a plurality of air holes 1111 on the surface capable of adsorbing the cleaning sheet, that is, a plurality of air holes 1111 are provided on the first surface. These air holes 1111 may be arranged according to a certain rule so as to make the air pressure formed on the first surface of the suction and release member 111 more uniform.

[0078] Understandably, continuing Figure 4 As shown, since the air pressure is controlled by the air pressure control member 112, the present application provides an air pipe connecting hole 1112 on the second surface of the suction and release member 111 opposite to the first surface, so that the air pressure control member 112 is connected to the air pipe connecting hole 1112 through a pipe, and the gas in the cavity of the suction and release member 111 is sucked and blown through the air pipe connecting hole 1112. Exemplarily, the pipe can be an integrated structure with the air pipe connecting hole 1112 and the air pressure control member 112, so as to prevent the pipe from being loosely connected to the air pipe connecting hole 1112 and the air pressure connection member, resulting in gas leakage, thereby affecting the suction and release effect of the suction and release member 111.

[0079] In an optional embodiment, since the cleaning device provided by the present application is used to clean the die lip 4011, the shape of the suction cup 1113 needs to match the shape of the die lip 4011, so that it can better fit the edge of the die lip 4011 and achieve thorough cleaning. Since the die lip 4011 is a V-shaped structure, the suction and release member 111 of the present application can be configured as follows: Figure 5 In the structure shown, the suction and release member 111 includes a suction cup 1113, and the suction cup 1113 includes a first sub-section 11131 and a second sub-section 11132. One end of the first sub-section 11131 and the second sub-section 11132 are connected to form a V-shaped hinge structure, and air holes 1111 are provided on the opposite surfaces of the first sub-section 11131 and the second sub-section 11132. An air pipe connecting hole 1112 is provided on the surface of the first sub-section 11131 away from the second sub-section 11132, or an air pipe connecting hole 1112 is provided on the surface of the second sub-section 11132 away from the first sub-section 11131.

[0080] The suction cup 1113 is composed of two sub-parts of the same shape and structure. The first sub-part 11131 and the second sub-part 11132 are both rectangular parallelepiped structures. The first sub-part 11131 and the second sub-part 11132 can connect one pair of long sides or one pair of short sides together and separate the other pair of long sides or the other pair of short sides, thereby forming a V-shaped hinge structure.

[0081] Similarly, in order to better control the air pressure in the cavity of the suction cup 1113, the first sub-section 11131 and the second sub-section 11132 of the suction cup 1113 are also formed by connecting the edges of double-layer materials to form the cavity of the first sub-section 11131 and the cavity of the second sub-section 11132. At the same time, a plurality of air holes 1111 are provided on the surface opposite to the first sub-section 11131 and the second sub-section 11132, and a plurality of air holes 1111 are provided on the surface opposite to the second sub-section 11132 and the first sub-section 11131. In addition, in order to control the air pressure of the suction cup 1113 through the air pressure control part 112, an air pipe connection hole 1112 is provided on the surface of the first sub-section 11131 away from the second sub-section 11132, or an air pipe connection hole 1112 is provided on the surface of the second sub-section 11132 away from the first sub-section 11131. Since one end of the first sub-section 11131 and the second sub-section 11132 are connected, the air pressure in the internal cavity of the first sub-section 11131 and the second sub-section 11132 can be controlled regardless of whether the trachea connection hole 1112 is set on the first sub-section 11131 or the second sub-section 11132.

[0082] In another embodiment, since the suction and placement member 111 needs to be moved under the drive of the first driving assembly 120, that is, the suction cup 1113 needs to be moved under the drive of the first driving assembly 120, continue as shown in FIG. Figure 5 As shown, based on the above description of the structure of the suction cup 1113, it is also necessary to use the suction cup 1113 connection part 1114 to associate the suction cup 1113 with the first drive assembly 120 to realize the control of the suction cup 1113 by the first drive assembly 120. Since the suction cup 1113 needs to reach the target position by translation, rotation, lifting, etc., it is necessary to flexibly connect the suction cup 1113 connection part 1114 with the first drive assembly 120, that is, the suction cup 1113 connection part 1114 is fixedly connected to the suction cup 1113. Specifically, the side connecting the first sub-section 11131 and the second sub-section 11132 is fixed on the suction cup 1113 connection part 1114. The material of the suction cup 1113 connection part 1114 can be different from the material of the suction cup 1113. The suction cup 1113 can be connected to the suction cup 1113 connection part 1114 by bonding, plugging, snapping, etc. Illustratively, the connection portion 1114 of the suction cup 1113 is a rectangular parallelepiped structure or a cube structure.

[0083] Below, a possible structure of the first driving assembly 120 is exemplarily described.

[0084] like Figure 6 As shown, the first driving component 120 may include a power member 121 and a transmission member 122 . The transmission member 122 passes through the adsorption component 110 . The power member 121 is used to drive the adsorption component 110 to move on the transmission member 122 .

[0085] The power element 121 provides power for the adsorption assembly 110 to move on the transmission element 122. For example, this power can be provided by a motor. The transmission element 122 is used to guide the movement path of the adsorption assembly 110. Therefore, the adsorption assembly 110 needs to be placed on the transmission element 122 to define the movement path of the adsorption assembly 110, allowing the adsorption assembly 110 to translate, rotate, etc. along the transmission element 122.

[0086] Illustratively, the present application may be that a through hole is opened on the connection portion 1114 of the suction cup 1113 , and the transmission member 122 is passed through the through hole to achieve a movable connection between the connection portion 1114 of the suction cup 1113 and the transmission member 122 .

[0087] In another optional embodiment, Figure 7 As shown, the power member 121 includes a first power unit 1211 and a second power unit 1212. The first power unit 1211 is provided at both ends of the transmission member 122 and is used to drive the adsorption assembly 110 to move along the length direction of the transmission member 122; the second power unit 1212 is connected to the transmission member 122 via a conversion member 123 and is used to drive the adsorption assembly 110 to rotate along the axial direction of the transmission member. In other words, the first power unit 1211 is used to provide power for the suction cup 1113 and the connecting portion 1114 in the adsorption assembly 110 to translate along the length direction of the transmission member 122. The second power unit 1212 is used to provide power for the suction cup 1113 and the connecting portion 1114 in the adsorption assembly 110 to rotate along the axial direction of the transmission member.

[0088] For example, Figure 8 As shown, the first power unit 1211 may include a pair of first motors 12111 arranged opposite to each other and a belt 12112 arranged corresponding to the pair of first motors 12111 .

[0089] In addition, in order to fix the first motor 12111 and the transmission member 122, continue as follows Figure 8As shown, the present application provides a first fixing portion 12113 and a second fixing portion 12114 at both ends of the transmission member 122, and a first fixing hole is opened on the surface of the first fixing portion 12113 relative to the second fixing portion 12114, and the first end of the transmission member 122 is inserted into the first fixing hole; a second fixing hole is opened on the surface of the second fixing portion 12114 relative to the first fixing portion 12113, and the second end of the transmission member 122 is inserted into the second fixing hole, thereby realizing the fixation of the transmission member 122.

[0090] like Figure 9 As shown, both the first fixing portion 12113 and the second fixing portion 12114 include a cavity. The surfaces of the first fixing portion 12113 and the second fixing portion 12114 facing the first motor 12111 may be provided with a hole for passing the belt 12112, or the surfaces of the first fixing portion 12113 and the second fixing portion 12114 facing the first motor 12111 may be uncovered. This can also achieve a transmission connection between the belt 12112 and the transmission member 122. Therefore, one end of the belt 12112 is disposed on the rotating shaft of the first motor 12111, and the other end is disposed on the transmission member 122. When the first motor 12111 is operating, it drives the belt 12112 to rotate the transmission member 122, thereby causing the connection portion 1114 of the suction cup 1113 to move along the length of the transmission member 122.

[0091] Optionally, continue as Figure 9 As shown, the transmission member 122 includes a first screw rod 1222 and a guide shaft 1221. The first screw rod 1222 is connected to the first motor 12111 via a belt 12112. The guide shaft 1221 is arranged parallel to the first screw rod 1222. The guide shaft 1221 is used to provide a guide for the connection portion 1114 of the suction cup 1113 to move along the length of the transmission member 122. The first screw rod 1222 cooperates with the first motor 12111 and the belt 12112 to achieve movement of the connection portion 1114 of the suction cup 1113 along the length of the transmission member 122. Therefore, the first fixing hole and the second fixing hole each include two sub-holes, one for fixing the first screw rod 1222 and the other for fixing the guide shaft 1221.

[0092] Continue as Figure 9As shown, since the first power unit 1211 can only provide power for the adsorption component 110 to move along the length direction of the transmission member 122, and cannot provide power for the adsorption component 110 to rotate axially along the transmission member 122, but the material storage frame 220 and the die head lip 4011 in this application are set at different positions, it is necessary to rotate the adsorption component 110 to achieve the adsorption of the cleaning sheet from the material storage frame 220 relative to the opening of the material storage frame 220, and the adsorption component 110 and the die head lip 4011 relative to achieve reciprocating movement relative to the die head lip 4011 to clean the die head lip 4011, so this application A second power unit 1212 is also provided. If the second power unit 1212 is directly connected to the transmission member 122, the adsorption component 110 cannot be rotated axially along the transmission member 122. Because the connection part 1114 of the suction cup 1113 is passed through the transmission member 122, it needs to be connected to the transmission member 122 through the conversion member 123, and the second power unit 1212 needs to be fixedly connected to the conversion member 123. In this way, when the second power unit 1212 is working, the conversion member 123 can rotate along with the rotation of the second power unit 1212, thereby driving the entire transmission member 122 to rotate, so as to realize the rotation of the adsorption component 110.

[0093] For example, continue as Figure 9 As shown, the second power unit 1212 can include a pair of second motors 12121 arranged opposite to each other, and a connecting rod 12122 for connecting to the corresponding conversion member 123, one end of the connecting rod 12122 is sleeved on the second motor 12121, and the other end is fixedly connected to the conversion member 123.

[0094] It can be understood that the second motor 12121 can be arranged on the surface of the conversion member 123 away from the transmission member 122, and the first motor 12111, the first fixing part 12113 and the second fixing part 12114 can be arranged on the surface of the conversion member 123 close to the transmission member 122, that is, the first motor 12111 and the second motor 12121 are respectively arranged on two opposite surfaces of the conversion member 123.

[0095] Optionally, the conversion member 123 is, for example, a triangular structure, a cube structure, a rectangular parallelepiped structure, etc.

[0096] Through the above description of the possible structure of the first drive assembly 120, it can be known that when the cleaning device provided by the present application needs to perform a cleaning operation on the die head lip 4011, the first motor 12111 can be first controlled to work to drive the belt 12112 and the first screw rod 1222 to move the connection part 1114 of the suction cup 1113 to just above the material storage frame 220, and then the second motor 12121 can be controlled to work to drive the conversion member 123 and the transmission member 122 to rotate together to rotate the connection part 1114 of the suction cup 1113 to the outlet direction of the V-shaped opening of the suction cup 1113 toward the material storage frame 220. Then, the air pressure control member 112 is controlled to suck air so that a negative pressure is present in the cavity of the suction cup 1113, thereby sucking out the cleaning sheet in the material storage frame 220.

[0097] Similarly, after the suction cup 1113 absorbs the cleaning sheet, the first motor 12111 is controlled to work to drive the belt 12112 and the first screw rod 1222 to move the connection part 1114 of the suction cup 1113 to a position relative to the die lip 4011, and then the second motor 12121 is controlled to work to drive the conversion part 123 and the transmission part 122 to rotate together to rotate the connection part 1114 of the suction cup 1113 until the V-shaped opening of the suction cup 1113 contacts the die lip 4011, stop the second motor 12121, and continue to control the first motor 12111 to work to drive the belt 12112 and the first screw rod 1222 to move back and forth along the surface of the die lip 4011, so that the cleaning sheet absorbed on the suction cup 1113 can wipe the surface of the die lip 4011 back and forth, thereby cleaning the die lip 4011.

[0098] It is understandable that, during the process of the suction cup 1113 adsorbing the cleaning sheet until the die lip 4011 is cleaned, the air pressure control component 112 can continuously provide negative pressure to the suction cup 1113 to prevent the cleaning sheet from falling off from the suction cup 1113 and affecting the wiping effect.

[0099] like Figure 10 As shown, the storage frame 220 may be stacked with multiple cleaning sheets. Since the cleaning sheets are used to clean the die head lip 4011, in order to ensure the cleaning effect, the present application further installs a storage box 210 outside the storage frame 220, and stores the storage frame 220 in the storage box 210. The outlet of the storage box 210210 may also be equipped with a cover. When the adsorption component 110 does not need to adsorb the cleaning sheet, the cover on the storage box 210 may be a cover provided at the outlet to prevent dust and impurities from entering the storage frame 220 and contaminating the cleaning sheet in the storage frame 220.

[0100] Such a setting may make it difficult for the adsorption component 110 to adsorb the cleaning sheet, so the present application further provides a second drive component 230 in the storage box 210 , which can push the storage frame 220 toward the outlet of the storage box 210 .

[0101] Optionally, the second drive assembly 230 includes a cylinder 2302 and a push rod 2301. When the adsorption assembly 110 needs to adsorb the cleaning sheet, the cylinder 2302 works to extend the push rod 2301 to push the storage frame 220 out of the storage box 210, thereby reducing the distance between the storage frame 220 and the suction cup 1113, making it easier for the suction cup 1113 to adsorb. It is understandable that when the adsorption assembly 110 does not need to adsorb the cleaning sheet, the cylinder 2302 works to shorten the push rod 2301 to retract the storage frame 220 into the storage box 210.

[0102] Optionally, the cleaning sheet is dust-free paper. The dust-free paper can be folded into a ladder-shaped stack (such as Figure 10 The side shape shown is a trapezoid) in the storage frame 220, then the shape of the bottom of the storage frame 220 can also be set to a trapezoidal structure in order to better store the dust-free paper. Since the upper bottom part of the trapezoid at the bottom of the storage frame 220 is a plane, the push rod 2301 can be fixedly connected to the upper bottom part of the trapezoid at the bottom of the storage frame 220, which makes the connection easier and also makes the push rod 2301 in the middle position of the bottom of the storage frame 220. The force on the push rod 2301 will also be more uniform, and the push rod 2301 will also be more stable during the extension and contraction process.

[0103] like Figure 11 As shown, after the suction cup 1113 has absorbed the cleaning sheet and cleaned the die lip 4011, the dirty cleaning sheet needs to be recovered. Therefore, the cleaning device of the present application also includes a recovery mechanism 300. The first drive assembly 120 is also used to drive the suction assembly 110 to a position opposite the recovery mechanism 300. The suction assembly 110 is also used to release the cleaning sheet to the recovery mechanism 300. Exemplarily, the recovery mechanism 300 is a box that matches the area of the cleaning sheet and has no cover.

[0104] For example, when the cleaning sheet needs to be recovered, the first motor 12111 can be controlled to operate first, driving the belt 12112 and the first screw 1222 to move the connection portion 1114 of the suction cup 1113 to directly above the recovery mechanism 300. The second motor 12121 can then be controlled to operate, driving the conversion member 123 and the transmission member 122 to rotate together, thereby rotating the connection portion 1114 of the suction cup 1113 until the V-shaped opening of the suction cup 1113 faces the entrance of the recovery mechanism 300. The air pressure control member 112 can then be controlled to blow air to create a positive pressure in the cavity of the suction cup 1113, thereby releasing the cleaning sheet adsorbed on the suction cup 1113 to the recovery mechanism 300.

[0105] like Figure 11 As shown, the present application also provides a coating device 1, which includes the cleaning device 1010 of the die lip 4011, the fixing device 2020, the material rolling device 3030 and the slurry spraying device 4040;

[0106] The cleaning device 10 of the die lip 4011, the material crushing device 30 and the slurry spraying device 40 are all installed on the fixing device 20, and the cleaning device 10 of the die lip 4011 is arranged between the material crushing device 30 and the slurry spraying device 40;

[0107] The slurry spraying device 40 includes a die head 401 , and a die head lip 4011 is provided on the die head 401 ;

[0108] The slurry in the cavity of the die 401 is transferred to the substrate wound on the material rolling device 30 through the die lip 4011;

[0109] The cleaning device 10 of the die lip 4011 is used to move to a position opposite to the die lip 4011 and reciprocate relative to the die lip 4011 to clean the die lip 4011 .

[0110] The fixing device 20 is used to fix the cleaning device 10 , the material crushing device 30 and the slurry spraying device 40 of the die lip 4011 .

[0111] like Figure 12 As shown, the fixing device 20 is, for example, a structure formed by three surfaces, wherein two side surfaces are arranged opposite each other, a bottom surface is arranged perpendicular to the two side surfaces, and the lower bottoms of the two side surfaces are connected to the two side surfaces of the bottom surface. Slide rails 201 are arranged on the upper surfaces of the two side surfaces opposite the lower bottoms.

[0112] like Figure 13As shown, a die head 401 assembly is mounted on the upper surface of the slide rail 201. The die head 401 assembly includes a die head body 401 and a die head base 402. The die head body 401 is fixed to the upper surface of the die head base 402. The die head base 402 is a T-shaped structure, wherein the vertical portion thereof passes through the slide rail 201 and is movably connected to the third drive assembly 403. The third drive assembly 403 includes a third motor 4031 and a second screw rod 4032. The second screw rod 4032 is disposed in a through hole provided in the vertical portion of the die head base 402. When the third motor 4031 is in operation, it drives the second screw rod 4032 to rotate, thereby causing the die head base 402 to slide on the slide rail 201, thereby causing the die head lip 4011 of the die head 401 to move closer to or away from the material crushing device 30.

[0113] When the die lip 4011 approaches the material crushing device 30 , the slurry in the cavity of the die 401 is transferred to the substrate wound on the material crushing device 30 through the die lip 4011 .

[0114] When the die 401 stops working and the die lip 4011 is away from the material crushing device 30 , the cleaning device 10 of the die lip 4011 moves to a position opposite to the die lip 4011 and reciprocates relative to the die lip 4011 to clean the die lip 4011 .

[0115] It should be noted that in order to facilitate the cleaning of the die lip 4011, the cleaning device 10 of the die lip 4011 can be set between the material crushing device 30 and the slurry spraying device 40. When the die lip 4011 does not need to be cleaned, the suction cup 1113 can be rotated to a position opposite to the bottom surface of the fixing device 20, or it can be moved to both ends of the transmission part 122 to avoid touching the die 401 and affecting the operation of the die 401.

[0116] The present application provides a cleaning device 10 and a coating device 1 for a die lip 4011, taking into account that in the prior art, during the operation of the die 401, coating slurry is likely to remain on the die lip 4011, and the coating slurry is likely to solidify and cause clogging of the die lip 4011, thereby affecting subsequent coating efficiency and coating quality. The cleaning device 10 for the die lip 4011 provided in the present application includes a cleaning mechanism 100 and a storage mechanism 200. The cleaning mechanism 100 includes an adsorption component 110 and a first drive component 120. The storage mechanism 200 includes a storage frame 220 with a cleaning sheet arranged therein. When the die lip 4011 needs to be cleaned, the first drive component 120 drives the adsorption component 110 to move to the storage frame 220 and adsorbs the cleaning sheet from the storage frame 220. Then, the first drive component 120 drives the adsorption component 110 to move to a position opposite to the die lip 4011 and controls the adsorption component 110 to move back and forth relative to the die lip 4011, so that the cleaning sheet adsorbed on the adsorption component 110 automatically cleans the die lip 4011. The cleaning device provided in the present application does not require human intervention during the cleaning process of the die lip 4011, which can prevent the risk of hand pinching and improve the safety of cleaning. In addition, the cleaning device provided in the present application can automatically clean the die lip 4011 and can repeatedly wipe the die lip 4011, which can improve the cleaning efficiency and cleaning effect.
