[0043] As Figure 1 and Figure 2 shown, the coating machine provided by the embodiments of the present invention includes a fixing device 100, a flipping device 200, and a lifting device 300. The flipping device 200 includes a rotating shaft 210 and a first driving assembly 220. The fixing device 100 is used to fix the material. The fixing device 100 is disposed on the rotating shaft 210. The first driving assembly 220 is connected to the rotating shaft 210 and is used to drive the rotating shaft 210 to rotate. The lifting device 300 is connected to the rotating shaft 210 and is used to drive the rotating shaft 210 to lift.

[0044] The coating machine according to the embodiment of the present invention is an automatic coating machine suitable for waffle cone products. The fixing device 100 is used to fix the waffle cone 510 of the product 500. The fixing device 100 is carried on the rotating shaft 210 of the flipping device 200, so that the rotating shaft 210 and the fixing device 100 form an integral structure. The first driving component 220 drives the rotating shaft 210 to rotate self, and then drives the fixing device 100 to rotate by a certain angle. The lifting device 300 is connected to the rotating shaft 210 to drive the rotating shaft 210 to lift, and then drives the fixing device 100 to lift by a certain height. The first driving component 220 drives the rotating shaft 210 to rotate forward by a certain angle, driving the fixing device 100 to flip so that the originally upward waffle cone 510 faces downward. Then the lifting device 300 drives the rotating shaft 210 to descend by a certain height, driving the fixing device 100 to descend so that the crown 520 of the product 500 is immersed in the dipping liquid surface. The fixing device 100 needs to maintain a certain time at this position until the material coated on the crown 520 of the product 500 is completely dried and no longer drips. Then the lifting device 300 drives the rotating shaft 210 to rise by a certain height, driving the fixing device 100 to rise so that the crown 520 of the product 500 leaves the dipping liquid surface. The first driving component 220 drives the rotating shaft 210 to rotate reversely by a certain angle, driving the fixing device 100 to flip so that the downward waffle cone 510 faces upward, completing a coating operation.

[0045] The present invention can uniformly control and adjust the flipping angle, the depth of immersion in the dipping material, the immersion duration, etc. of the product 500 by controlling the first driving member and the lifting device 300. As long as the operator places the product 500 to be coated on the fixing device 100, the fixing device 100 fixes the product 500 to be coated, the flipping device 200 flips it, and the lifting device 300 lifts and lowers it, automatically completing the operation of coating and dipping the product 500, reducing the working intensity of the operator, being simple and easy to adjust in operation, and having high coating control accuracy. It changes the manual coating operation mode of the prior art, reduces the risk of product 500 quality pollution caused by manual operation, improves the reliability of the equipment, eliminates the pollution risk, and also improves the yield data and coating efficiency of the product 500.

[0046] Such as Figure 1 、 Figure 2 and Figure 3As shown, according to an embodiment provided by the present invention, the first driving assembly 220 includes a first driver 221 and a swing rod 222. One end of the swing rod 222 is connected to the output shaft of the first driver 221, and the other end of the swing rod 222 is fixedly connected to the rotating shaft 210 through the first connecting portion 225. The output shaft of the first driver 221 is axially parallel to the rotating shaft 210. In this embodiment, the swing rod 222 is vertically connected to the rotating shaft 210 and the output shaft of the first driver 221 axially, and the output shaft of the first driving shaft of the rotating shaft 210 is arranged in parallel. When the output shaft of the first driver 221 rotates, it drives the swing rod 222 fixedly connected to the output shaft to swing by a certain angle. Through the action conversion of the first connecting portion 225, the swing of the swing rod 222 is converted into the rotation of the rotating shaft 210, thereby driving the fixing device 100 to rotate by a certain angle.

[0047] In this embodiment, the first driver 221 adopts a linear motor, a frequency conversion motor, etc. that can achieve forward and reverse rotation.

[0048] As Figure 2 、 Figure 3 and Figure 8 As shown, according to an embodiment provided by the present invention, the first driving assembly 220 further includes an internal gear ring 223 and a gear 224. The gear 224 is located inside the internal gear ring 223 and is meshed with the gear ring. The gear 224 is coaxially connected to the output shaft of the first driver 221, and the swing rod 222 is connected to the end face of the gear 224. In this embodiment, the output shaft of the first driver 221 drives the swing rod 222 to rotate. Through the action conversion of the first connecting portion 225, the swing of the swing rod 222 is converted into the rotation of the rotating shaft 210 and the position change of the whole first driver 221 and the gear 224. While the first driver 221 moves synchronously to drive the gear 224 to rotate, it meshes with the internal gear ring 223. Under the cooperation of the gear 224 and the internal gear ring 223, on the one hand, it provides a supporting effect on the first driver 221, and on the other hand, it ensures the stable movement conversion between the first driver 221 and the swing rod 222.

[0049] Define the end of the swing rod 222 connected to the output shaft of the first driver 221 as the first end, and the end of the swing rod 222 connected to the rotating shaft 210 as the second end. The first driver 221 drives the first end to rotate. The swing rod 222 swings by a certain angle with the first end as the center. The second end makes an arc movement. Under the action of the first connecting portion 225, the arc movement of the second end is converted into the rotation of the second end, that is, the swing rod 222 swings by a certain angle with the second end as the center, and the first end makes an arc movement, that is, the gear 224 rotates on the output shaft of the first driver 221 while meshing and revolving on the internal gear ring 223, so that the whole first driver 221 moves along the internal gear ring 223 in an arc. In this way, the fixing device 100 only makes a rotating motion and does not generate an arc motion with a height change, simplifying the device and the motion.

[0050] As Figure 3 shown, according to an embodiment provided by the present invention, the first connecting portion 225 includes a boss 2251 and a first jack 2252 that cooperates with the boss 2251. Both the boss 2251 and the first jack 2252 are polygonal shapes. One of the boss 2251 and the first jack 2252 is disposed on the end face of the rotating shaft 210, and the other is disposed on the swing rod 222. In this embodiment, the end of the rotating shaft 210 is connected to the swing rod 222. The boss 2251 is disposed at the end of the rotating shaft 210, and the first jack 2252 is disposed at the end of the swing rod 222. The boss 2251 is inserted into the first jack 2252. During the process that the end of the swing rod 222 connected to the first driver 221 swings by a certain angle, the end of the swing rod 222 where the first jack 2252 is disposed rotates self, and the rotation of the first jack 2252 drives the boss 2251 to rotate self, that is, the rotating shaft 210 rotates by a certain angle. The polygonal boss 2251 and the first jack 2252 cooperate with each other, and can drive each other to rotate synchronously and in the same direction, without relative and reverse rotation.

[0051] In another embodiment, the first jack 2252 is disposed at the end of the rotating shaft 210, and the boss 2251 is disposed at the end of the swing rod 222. The boss 2251 is inserted into the first jack 2252. During the process that the end of the swing rod 222 connected to the first driver 221 swings by a certain angle, the end of the swing rod 222 where the boss 2251 is disposed rotates self, and the rotation of the boss 2251 drives the first jack 2252 to rotate self, that is, the rotating shaft 210 rotates by a certain angle.

[0052] In this embodiment, the boss 2251 is a square boss 2251, and the first jack 2252 is a square jack. In other embodiments, other polygonal shapes such as triangles and hexagons can also be used, as long as they are not circular.

[0053] As Figure 2 and Figure 8 shown, according to an embodiment provided by the present invention, the swing rod 222 is fixedly connected to the body of the first driver 221 through a connecting member 226. In this embodiment, the swing rod 222 is divided into two sections. One section is a rectangular strip, and the other section is a square plate. The rectangular section is disposed in the middle line direction of the square section. The rectangular section is connected to the rotating shaft 210, and the square section is connected to the first driver 221. The output shaft of the first driver 221 is connected to the central position of the square section. Four corners of the square section are connected to the body of the first driver 221 through the connecting member 226. The gear 224 and the internal gear ring 223 are located in the space between the square section and the body of the first driver 221. The connecting member 226 fixes the swing rod 222 and the first driver 221 into a whole, improves the structural stability of the first driver 221 and the swing rod 222, and at the same time ensures that the two can swing synchronously under the meshing action of the gear 224 and the internal gear ring 223.

[0054] In this embodiment, the connecting member 226 is a bolt, and mounting holes for installing the bolt are respectively provided at the four corners of the square section. Mounting holes for installing the bolt are also correspondingly provided on the body of the first driver 221.

[0055] Such as Figure 1 , Figure 2 and Figure 3 As shown in, according to an embodiment provided by the present invention, the lifting device 300 includes a second driving assembly 310 and a bushing 320. The bushing 320 is sleeved outside the rotating shaft 210. The second driving assembly 310 is connected to the bushing 320 and is used to drive the rotating shaft 210 to lift. In this embodiment, the bushing 320 is coaxially arranged on the rotating shaft 210. The rotating shaft 210 rotates within the bushing 320. The second driving assembly 310 is connected to the bushing 320. After the turning device 200 controls the fixing device 100 to complete turning, the second driving assembly 310 drives the bushing 320 to lift, that is, drives the rotating shaft 210 and the fixing device 100 fixed on the rotating shaft 210 to lift. Thus, through the cooperation of the bushing 320 and the second driving assembly 310, the control of the fixing device 100 by the lifting device 300 does not affect the control action of the turning device 200 on the fixing device 100.

[0056] Both the first driving assembly 220 and the rotating shaft 210 are one. The lifting device 300 can be provided with one or two. In this embodiment, there are two lifting devices 300, which are respectively located at positions close to both ends of the rotating shaft 210 for bilateral driving. One bushing 320 is sleeved at the end of the rotating shaft 210, and the other bushing 320 is sleeved at the end of the rotating shaft 210 close to the boss 2251. The two lifting devices 300 can play a role in supporting balance, improve the structural strength and lifting stability, and the two driving assemblies can be synchronously controlled for driving. In other embodiments, the lifting device 300 can also be one, for synchronously lifting the rotating shaft 210, the fixing device 100 and the first driving assembly 220 for unilateral driving.

[0057] Such as Figure 2 and Figure 3As shown, according to an embodiment provided by the present invention, the second driving component 310 includes a second driver 311 and a connecting rod 312. One end of the connecting rod 312 is rotatably connected to the output shaft of the second driver 311 through a second connecting portion 314, and the other end of the connecting rod 312 is connected to the bushing 320. In this embodiment, the output shaft of the second driver 311 is connected to the connecting rod 312 to drive the connecting rod 312 to move up and down along its axial direction. The connecting rod 312 is connected to the bushing 320, and while moving up and down, it drives the rotating shaft 210 to move up and down. The connecting rod 312 is coaxially arranged with the output shaft of the second driver 311, and the axial direction of the connecting rod 312 is perpendicular to the axial direction of the bushing 320, that is, the connecting rod 312 and the bushing 320 can form a T-shaped structure by welding or integral molding, etc. During the process of the first driver 221 driving the rotating shaft 210 to rotate, the rotating shaft 210 may cause the bushing 320 to rotate slightly while rotating, thereby causing the connecting rod 312 to swing slightly. The second connecting portion 314 rotatably connects the output shaft of the second driver 311 to the connecting rod 312, enabling a relative rotation at a certain angle between the connecting rod 312 and the output shaft of the second driver 311, while not hindering the second driver 311 from driving the connecting rod 312 to move up and down.

[0058] In this embodiment, the second driver 311 can adopt a lifting drive device such as a cylinder or a hydraulic cylinder that can control the lifting height. The length of the connecting rod 312 can be changed according to actual applications to adapt to the device layout and the height adjustment of the fixing device 100.

[0059] As Figure 2 and Figure 3 As shown, according to an embodiment provided by the present invention, the second driving component 310 further includes a first guiding member 313, and the first guiding member 313 is connected to the connecting rod 312. In this embodiment, the first guiding member 313 is arranged outside the connecting rod 312. During the process of the second driver 311 driving the connecting rod 312 to move up and down, it guides and limits the movement of the connecting rod 312, stabilizing the up and down movement trajectory of the connecting rod 312 along its axial direction, and avoiding deflection and swing of the connecting rod 312 during the movement process.

[0060] As Figure 2 and Figure 3As shown, according to an embodiment provided by the present invention, the first guide member 313 includes a guide sleeve 3131. The guide sleeve 3131 is sleeved outside the connecting rod 312. A strip-shaped hole 3132 is provided on the guide sleeve 3131. The strip-shaped hole 3132 extends along the axial direction of the connecting rod 312. The second connecting portion 314 can move within the strip-shaped hole 3132. In this embodiment, the first guide member 313 is the guide sleeve 3131. The guide sleeve 3131 has a cylindrical structure, and the strip-shaped hole 3132 is provided along the axial direction of the connecting rod 312. The connecting rod 312 is located inside the guide sleeve 3131. When the second driver 311 drives the connecting rod 312 to move, the connecting rod 312 moves linearly along its axial direction inside the guide sleeve 3131. The strip-shaped hole 3132 provides a moving space for the second connecting portion 314, enabling the guide sleeve 3131 to not only guide the movement of the connecting rod 312 but also not affect the position change of the connection between the output shaft of the second driver 311 and the connecting rod 312 during the lifting process, so that the lifting device 300 can more smoothly adjust the lifting of the rotating shaft 210 and the fixing device 100.

[0061] In other embodiments, the first guide member 313 can also be a guide sleeve 3131 without a striped hole, and the length of the guide sleeve 3131 is required to be shorter, that is, during the driving and lifting stroke of the second driver 311, the second connecting portion 314 has no contact with the guide sleeve 3131. The first guide member 313 can also be a combination of a slider and a slide rail. The slider can slide along the slide rail. One of the slider and the slide rail is arranged on the connecting rod 312, and the other cooperates with it to limit and guide the guide rod.

[0062] As Figure 3 As shown, according to an embodiment provided by the present invention, the second connecting portion 314 includes an insertion shaft 3141 and a second insertion hole 3142. The insertion shaft 3141 is inserted into the second insertion hole 3142. One of the insertion shaft 3141 and the second insertion hole 3142 is arranged on the output shaft of the second driver 311, and the other is arranged on the connecting rod 312. In this embodiment, the second insertion hole 3142 is arranged on the output shaft of the second driver 311, and the insertion shaft 3141 is arranged on the side wall at the lower end of the connecting rod 312. The axial direction of the insertion shaft 3141 is perpendicular to the axial direction of the connecting rod 312. The insertion shaft 3141 is inserted into the insertion hole and can rotate in the second insertion hole 3142. When the output shaft of the second driver 311 moves, the insertion shaft 3141 can be pushed and pulled through the second insertion hole 3142 to realize the lifting of the connecting rod 312. At the same time, when the connecting rod 312 swings slightly, the insertion shaft 3141 can also rotate correspondingly in the second insertion hole 3142, making the structure more flexible.

[0063] In other embodiments, a plug shaft 3141 is provided on the side wall of the output shaft of the second driver 311, and a second jack 3142 is provided on the side wall at the lower end of the connecting rod 312. The second jack 3142 is axially perpendicular to the axial direction of the connecting rod 312. The plug shaft 3141 is inserted into the jack and can rotate in the second jack 3142. When the output shaft of the second driver 311 moves, the second jack 3142 can be pushed and pulled through the plug shaft 3141 to realize the lifting of the connecting rod 312. At the same time, when the connecting rod 312 swings slightly, the plug shaft 3141 can also rotate correspondingly in the second jack 3142, making the structure more flexible.

[0064] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, according to an embodiment provided by the present invention, the fixing device 100 includes a locking assembly 110, a fixing bracket 120, and a third driving assembly 130. The fixing bracket 120 is connected to the rotating shaft 210. The fixing bracket 120 is provided with a positioning hole 121 for placing materials. The locking assembly 110 is stacked with the fixing bracket 120, and the third driving assembly 130 is connected to the locking assembly 110 for driving the locking assembly 110 to move relative to the fixing bracket 120 to fix the material. In this embodiment, the locking assembly 110 and the fixing bracket 120 are stacked parallel to each other. The cone 510 part of the product 500 is placed in the positioning hole 121 of the fixing bracket 120. The third driving assembly 130 drives the locking assembly 110 to move to lock the cone 510 part of the product 500, so as to fix the product 500 on the fixing bracket 120 and prevent the subsequent product 500 from flipping and falling off the fixing bracket 120 during the coating process and lifting. When the rotating shaft 210 rotates, the fixing bracket 120, the locking assembly 110, and the third driving assembly 130 rotate synchronously. When the rotating shaft 210 lifts, the fixing bracket 120, the locking assembly 110, and the third driving assembly 130 lift synchronously.

[0065] Through the third driving assembly 130, automatic control of the locking assembly 110 can be realized. That is, after the operator places the product 500 in the fixing hole of the fixing bracket 120, the locking and fixing of the product 500 are automatically completed by the third driving assembly 130 driving the locking assembly 110, without the operator manually locking the product 500. The locking force and locking state of the locking assembly 110 can be uniformly executed under the action of the third driving assembly 130, avoiding insufficient and non-uniform insertion depth of the steel needle caused by the fatigue of the operator, resulting in the product 500 falling into the coating material during flipping coating, preventing the loss of the product 500, affecting the yield rate of the current shift, and posing a pollution risk to the coating material.

[0066] As Figure 4 , Figure 5 , Figure 6 andFigure 7 As shown, according to an embodiment provided by the present invention, the locking assembly 110 includes a grid frame 111 and a pin 112. The grid frame 111 is arranged parallel to the fixed bracket 120. The third driving assembly 130 is connected to the grid frame 111 to drive the grid frame 111 to move. The grid frame 111 is provided with mesh holes 1111 corresponding to the positioning holes 121 one by one. The inner wall of each mesh hole 1111 is provided with a pin 112. The axial direction of the pin 112 is arranged along the moving direction of the grid frame 111 for inserting into the material to fix the material. In this embodiment, the locking assembly 110 is composed of a grid frame 111 and a pin 112. The grid frame 111 and the fixed bracket 120 are both horizontally arranged. The third driving assembly 130 can drive the grid frame 111 to move horizontally within a certain range. The mesh holes 1111 on the grid frame 111 are provided with pins 112 corresponding to the positioning holes 121. The pins 112 are also horizontally arranged and the tip direction points to the center position of the mesh hole 1111. And the aperture of the mesh hole 1111 needs to be larger than the aperture of the positioning hole 121 to provide a moving space range for the pin 112.

[0067] During the locking action, the third driving assembly 130 drives the grid frame 111 to move forward horizontally. The pin 112 gradually approaches the cone 510 of the product 500 in the positioning hole 121 until the insertion depth is in place. Then the third driving assembly 130 stops driving and the grid frame 111 stops moving. Even if the surface of the cone 510 of the product 500 has a paper tube, the pin 112 can still penetrate the paper tube and insert into the crispy skin of the product 500 to ensure the locking and fixing of the product 500 on the fixed bracket 120. During the unlocking action, the third driving assembly 130 drives the grid frame 111 to move backward horizontally. The pin 112 gradually moves away from the cone 510 of the product 500 in the positioning hole 121 until it is pulled out of the cone 510 and returns to its original position. Then the third driving assembly 130 stops driving and the grid frame 111 stops moving. Even if the pin 112 exits from the cone 510 of the product 500 and leaves the product 500, the unlocking of the product 500 on the fixed bracket 120 is completed.

[0068] In this embodiment, the fixed bracket 120 is arranged above the grid frame 111, and the pin 112 is inserted into a part of the cone 510 below the positioning hole 121. The third driving assembly 130 can adopt a jacking device such as a cylinder or a hydraulic cylinder. The jacking direction of its piston is the horizontal moving direction of the grid frame 111. The third driving member is installed on the lower surface of the fixed bracket 120 through a mounting seat, that is, on the side where the cone 510 of the product 500 is located. The setting of the mounting seat does not prevent the movement of the grid frame 111. At the same time, after the fixed bracket 120 is flipped, the third driving assembly 130 is on the same side as the cone 510 and faces upward, and will not contact the material, preventing pollution to the material and damage to the equipment.

[0069] In other embodiments, the fixed bracket 120 can also be arranged above the grid 111. Then, the third driving member can be arranged near the locking assembly 110 and other structures can also be adopted, such as clamping jaws, etc. The structure type and action requirements of the third driving assembly 130 are selected in cooperation with the locking assembly 110.

[0070] Such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in

[0071]

[0072] According to an embodiment provided by the present invention, a positioning cylinder 122 is arranged at the positioning hole 121. A notch 1221 is arranged on the side wall of the positioning cylinder 122, and the insertion pin 112 can be inserted into the inner side of the positioning cylinder 122 through the notch 1221. In this embodiment, the positioning hole 121 extends downward to form the positioning cylinder 122 that matches the shape of the brittle cylinder 510 of the product 500. The positioning cylinder 122 has a certain length. After the product 500 is placed, the brittle cylinder 510 is embedded in the positioning cylinder 122 to support and fix the product 500. Since the fixed bracket 120 is arranged above the grid 111 and the position of the insertion pin 112 on the grid 111 corresponds to the positioning cylinder 122, a notch 1221 facing the insertion pin 112 is arranged on the cylinder wall of the positioning cylinder 122, and the insertion pin 112 can be inserted into the brittle cylinder 510 part of the product 500 located in the positioning cylinder 122 through the through hole. Such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in

[0073] According to an embodiment provided by the present invention, a second guiding member 123 is arranged on the fixed bracket 120, and the fixed bracket 120 is connected to the locking assembly 110 through the second guiding member 123. In this embodiment, the second guiding member 123 is arranged on the fixed bracket 120. During the movement of the locking assembly 110, the second guiding member 123 is used to limit and guide it to ensure the stability of the movement of the locking assembly 110. At the same time, the second guiding member 123 can also connect the locking assembly 110 and the fixed bracket 120 into a whole to ensure the compactness of the device structure. Such as Figure 4 , Figure 5 , Figure 6 Figure 7As shown, according to an embodiment provided by the present invention, the second guiding member 123 includes a guiding block 1231. The guiding block 1231 is provided with a through groove 1232, and the through groove 1232 extends along the moving direction of the locking assembly 110. The grid frame 111 is embedded in the through groove 1232. In this embodiment, the second guiding member 123 is the guiding block 1231 with the through groove 1232. The guiding block 1231 is a bent plate in the shape of "ji". The middle position of the guiding block 1231 is the through groove 1232. The mesh holes 1111 of the grid frame 111 divide the grid frame 111 into horizontally and vertically staggered strip plates. The horizontal strip plates are perpendicular to the vertical strip plates, and the extending direction of the horizontal strip plates is parallel to the moving direction of the grid frame 111. Therefore, the horizontal strip plates are embedded in the through groove 1232. During the movement of the grid frame 111, the horizontal strip plates move along the through groove 1232 in the through groove 1232, thereby realizing stable guiding for the movement of the grid frame 111.

[0074] In this embodiment, since the grid frame 111 is arranged below the fixed bracket 120, the guiding block 1231 is arranged on the lower surface of the fixed bracket 120. The "ji"-shaped guiding block 1231 is inverted. The fixed bracket 120 is provided with hole positions for installing screws and the like, so that both sides of the through groove 1232 are fixed on the fixed bracket 120 through fasteners such as screws, that is, the notch of the through groove 1232 is covered by the fixed bracket 120, and the grid frame 111 is supported below the fixed bracket 120. In other embodiments, the position where the second guiding member 123 is arranged is adjusted according to the actual position of the locking assembly 110. The structural selection of the second guiding member 123 can also be designed according to the structural selection of the locking assembly 110 and its specific position, as long as it can support and position the locking assembly 110.

[0075] As Figure 1 and Figure 8 As shown, according to an embodiment provided by the present invention, the coating machine of the embodiment of the present invention further includes a material tank 400 for holding materials. The material tank 400 is located below the fixing device 100 and corresponds to the fixing device 100. In this embodiment, the material tank 400 holds dipping material and is arranged below the rotating shaft 210. After the flipping device 200 drives the fixing device 100 to flip, the crown part 520 of the product 500 faces the material tank 400. The lifting device 300 controls the height position of the fixing device 100, so that the crown part 520 of the product 500 is immersed in the dipping liquid in the material tank 400 for coating.

[0076] In this embodiment, the material tank 400 also has a temperature control function, which can control the fluidity and viscosity of the dipping liquid in the material tank 400. Two lifting devices 300 are respectively arranged on both sides of the material tank 400 and are connected to the ends of the rotating shaft 210, and the internal gear ring 223 and the second driver 311 are both fixed to the outer wall of the material tank 400, improving the overall structural compactness of the device.

[0077] AsFigure 1 and Figure 8 As shown in Figure 8 , according to an embodiment provided by the present invention, the material tank 400 includes a feeding component, an inner tank body 410, and an outer tank body 420. The inner tank body 410 is disposed inside the outer tank body 420, and the inner tank body 410 is also communicated with the outer tank body 420 through the feeding component. In this embodiment, the material tank 400 is divided into two inner and outer tank bodies. The outer tank body 420 is used to store the dipping material and has a temperature adjustment function. The inner tank body 410 is single-layered, and there are four columns at the bottom surface of the inner tank body 410, which are erected at corresponding positions inside the outer tank body 420. The inner tank is used for the product 500 to be coated. The dipping material in the outer tank body 420 is injected into the inner tank body 410 through the feeding component, and the dipping material in the inner tank body 410 can overflow into the outer tank body 420. To ensure the consistency of the coating liquid level, coating weight per unit area, and temperature, and continuously supply the dipping material to the outer tank body 420, the dipping material is always in a circulating flow state.

[0078] In this embodiment, the feeding component can adopt an external pump and pipeline.

[0079] According to an embodiment provided by the present invention, the notch position of the inner tank body 410 is lower than that of the outer tank body 420. In this embodiment, the notches of the inner tank body 410 and the outer tank body 420 are arranged in the same direction. The notch of the inner tank body 410 is lower than that of the outer tank body 420. The dipping material in the inner tank body 410 is used for the product 500 to be coated. The dipping material in the outer tank body 420 is injected into the inner tank body 410 through an external pump, and after being filled, it can directly overflow into the outer tank body 420 through the notch of the inner tank body 410.
