Description

Technical Field

[0001] This invention belongs to the technical field of roller coating equipment, specifically an automated roller coating device. Background Technology

[0002] Roller coating machines are important pieces of automated control roller coating equipment in the coating equipment series. They feature low paint loss, high production efficiency, and simple and convenient maintenance. They can be well integrated with production lines to form highly automated production lines. They are especially suitable for coating NC and UV paints, with optimal results. They are also suitable for coating PU and PE paints.

[0003] Existing roller coating machines consist of a frame, worktable, lifting seat, uniform coating head, and paint feeding system. The frame supports all machine components and, like a car chassis, forms the foundation of the entire equipment. The worktable is the equipment's feeding system and must operate smoothly. The lifting seat is the only adjustment system for the workpiece thickness, requiring easy and precise adjustment. The uniform coating head is the equipment's painting system, on which uniform coating rollers and uniform coating steel wheels are mounted. It consists of a paint pump, paint pipes, ball valves, pipe fittings, etc., and is responsible for drawing paint onto the uniform coating head.

[0004] The working principle of a roller coating machine is as follows: a uniformly distributed rubber roller and a uniformly distributed steel roller are parallel and close together, rotating inward at a constant speed, creating a V-shaped space in the middle. Paint flows evenly into this space. Adjusting the tightness between the rubber roller and the steel roller controls the thickness and uniformity of the paint adhering to the rubber roller. The plate is propelled forward at a constant speed by the conveyor belt, making appropriate contact with the rubber roller, thus transferring the paint evenly from the roller to the plate surface. The roller coating machine improves production efficiency, reduces paint consumption, and enhances product quality to meet the requirements of electronic assembly processes such as wave soldering. It features uniform coating thickness and convenient adjustment.

[0005] The existing roller coating machine can achieve efficient roller coating of boards and other materials. However, in the actual coating process, the coating is mostly fluid. Therefore, when coating with a roller, the fluid coating will flow to the surrounding area, which may lead to the possibility of coating splashing. On the one hand, this may affect the coating effect on the board, and on the other hand, it will cause problems such as difficulty in cleaning the inside of the roller coating machine and waste of coating. Summary of the Invention

[0006] To address the aforementioned problem of paint splattering, the present invention aims to provide an automated roller coating device that collects paint and reduces paint waste.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: an automated control roller coating device includes a housing, a transport frame and an output frame respectively provided on both sides of the housing, a partition plate provided inside the housing, the top and bottom of the partition plate being fixedly connected to the top wall and bottom wall of the housing respectively, and a through opening provided on the partition plate, which divides the interior of the housing into a transport chamber and a roller coating chamber.

[0008] The conveying chamber is equipped with a conveying assembly for conveying the sheet material, and the roller coating chamber is equipped with a roller coating assembly for roller coating the sheet material. The roller coating assembly includes a feed roller and a paint roller. Both the feed roller and the paint roller are embedded with hub motors for driving the feed roller and the paint roller. The hub motors are signal-connected to a controller. Both the feed roller and the paint roller are equipped with a first roller frame. The end of the first roller frame away from the feed roller and the paint roller is fixedly connected to a support member. The support member is fixedly connected to the top wall of the housing. The top wall of the roller coating chamber is also equipped with a paint inlet, which is located between the feed roller and the paint roller.

[0009] The roller coating chamber is also equipped with a fixing component, which includes hollow fixing plates symmetrically arranged on both sides of the coating roller. A hollow fixing block is fixedly connected to the lower part of the fixing plate near the coating roller. The fixing block can be located at the bottom of the plate and is used to support the plate. A feed port is provided at the end of the fixing plate near the coating roller. An inclined guide plate is fixedly connected inside the hollow part of the fixing plate. The guide plate is fixedly connected to the feed port. The end of the guide plate near the feed port is higher than the other end of the guide plate. The bottom end of the hollow part of the fixing plate is inclined in the opposite direction to the guide plate. A conveying port is provided on the side of the fixing plate near the fixing block. An inlet corresponding to the position of the conveying port is provided on the side of the fixing block near the fixing plate. The hollow part of the fixing plate and the hollow part of the fixing block are connected through the conveying port and the inlet.

[0010] The basic principle is as follows: the sheet material is placed from the transport frame into the conveying chamber, and the conveying assembly will transport the sheet material to the roller coating chamber. After the sheet material is transported into the roller coating chamber, it contacts the fixing assembly and the roller coating assembly. The two sides of the sheet material contact the fixing plate, the sheet material is located above the fixing block, and the top of the sheet material will contact the coating roller. First, the paint and other coatings flow in from the coating inlet, and the coatings will contact the feed roller and the coating roller in sequence. The feed roller will limit the thickness of the flowing coatings, and at the same time, the coating roller will contact the top of the sheet material and realize the coating operation on the top of the sheet material.

[0011] When coating the board, since the coating is mostly fluid, it flows to both sides of the board under the pressure of the coating roller. The coating will then come into contact with the fixed plates located on both sides of the board. The coating that overflows during coating comes into contact with the feed inlet. Under the guidance of the guide plate at the feed inlet, the coating flows to the hollow part of the fixed plate. Then, the coating will flow to the bottom of the fixed plate by gravity. The bottom of the fixed plate is inclined, and the hollow part of the fixed plate is connected to the hollow part of the fixed block through the feed port and the inlet. Therefore, the coating will flow into the hollow part of the fixed block to achieve material collection and storage.

[0012] The beneficial effects of the basic scheme are: 1. When applying paint, the paint roller will apply a certain pressure to the board, which requires a certain support force to the bottom of the board, so that the paint can be applied to the top of the board more firmly. Therefore, when the board is in the roller coating chamber and is located on the top of the fixed block, the fixed block will apply a certain support force to the board, so that the board can be coated with paint more stably.

[0013] 2. By combining the fixing plate and the fixing block, the plate can be supported, thus assisting the coating. At the same time, the excess coating that overflows during the application of the coating can be collected, thereby reducing material splashing and the problem of difficult cleaning of coating waste later. Furthermore, the collected coating can be reused after certain processing, thus reducing material waste.

[0014] Furthermore, the conveying assembly includes several conveying rollers, each of which is embedded with a hub motor for driving the conveying rollers. Each conveying roller is equipped with a second roller frame, and a support rod is fixedly connected to the other end of the second roller frame. The support rod is fixedly connected to the bottom wall of the housing.

[0015] A positioning assembly is provided above the conveyor roller closest to the partition plate. The positioning assembly includes a positioning roller, in which a hub motor for driving the positioning roller is embedded. A third roller frame is provided on the positioning roller, and a first electric control cylinder is fixedly connected to the other end of the third roller frame. The output shaft of the first electric control cylinder is fixedly connected to the third roller frame, and the cylinder body of the first electric control cylinder is fixedly connected to the top wall of the housing. Both the hub motor and the first electric control cylinder are connected to the controller signal.

[0016] The beneficial effects of the basic scheme are as follows: the hub motor inside the conveyor roller is started by the controller, which enables the conveyor roller to rotate. Under the action of the rotating conveyor roller, the board is gradually conveyed into the coating chamber for coating operation. During coating, the controller can start the first electric cylinder, and the positioning roller will move vertically downward, which plays a certain role in transporting and stabilizing the board. This reduces the problem of uneven force on the board and warping caused by levers during coating.

[0017] Furthermore, the fixing plate includes a top plate, an electric telescopic rod, and a bottom plate that are fixedly connected from top to bottom. A T-shaped first slider is fixedly connected to the top of the top plate, and a first groove corresponding to the first slider is provided on the top wall of the housing. The top plate and the housing slide laterally through the first slider and the first groove. The length of the bottom plate is greater than the length of the top plate, and the hollow part of the fixing plate is located inside the bottom plate.

[0018] A second electric control cylinder is fixedly connected to both sides of the base plate away from the plate material. The output shaft of the second electric control cylinder is fixedly connected to the base plate. A connecting block is fixedly connected to each cylinder body of the second electric control cylinder. A second slider is fixedly connected to each side of the connecting block away from the second electric control cylinder. A second sliding groove is provided on the inner side wall of the housing, corresponding to the position of the second slider. The connecting block and the housing slide vertically through the second slider and the second sliding groove. The electric telescopic rod and the second electric control cylinder are both connected to the controller signal.

[0019] The beneficial effects of the basic scheme are: by controlling the second electric cylinder to start, the base plate will move closer to or further away from the board under the action of the second electric cylinder, so that the base plate can always be in contact with both sides of the board, thus enabling the overflowing paint to be collected more smoothly; by controlling the electric telescopic rod to start, the base plate can move vertically up or down, so that the fixing block is always located below the board, thus supporting the board.

[0020] Furthermore, infrared sensors for measuring the width of the sheet material are installed on the inner sidewalls of the transport frame, and the infrared sensors are connected to the controller signal.

[0021] The beneficial effects of the basic solution are: the infrared sensor will collect the width information of the board material, and then the infrared sensor will transmit the collected information to the controller, which will receive and process the information.

[0022] Furthermore, a thickness measuring component is also provided inside the conveying chamber. The thickness measuring component includes a pressure measuring cylinder located above the conveying roller. The top of the pressure measuring cylinder is fixedly connected to the top wall of the housing. A pressure sensor is fixedly connected to the top wall of the pressure measuring cylinder. A piston is slidably fitted inside the pressure measuring cylinder. A piston rod is fixedly connected to the bottom of the piston. The piston rod passes through the bottom of the pressure measuring cylinder and extends to the outside of the pressure measuring cylinder. A compression ball is fixedly connected to the end of the piston rod away from the piston. The compression ball can contact the plate. The pressure sensor is connected to the controller signal.

[0023] The bottom of the piston is also fixedly connected to tension springs located on both sides of the piston rod, and the other end of the tension springs is fixedly connected to the bottom wall of the pressure measuring cylinder.

[0024] The beneficial effects of the basic scheme are as follows: After the sheet material moves into the conveying chamber, the extrusion ball will be squeezed by the sheet material. After the extrusion ball is squeezed, the piston rod will move upward, the piston block will move upward, and the pressure inside the pressure measuring cylinder will change. Then, the pressure sensor inside the pressure measuring cylinder will collect the pressure change value and transmit the pressure change value to the controller. The controller processes the data and calculates the corresponding sheet material thickness. By monitoring the pressure change value inside the pressure measuring cylinder, the position of the grooved area on the sheet material can be monitored. Subsequently, the controller can directly control the fixed component and the roller coating component to change accordingly, so that the coating at the grooved area is also more uniform.

[0025] Furthermore, the support component is a third electric control cylinder, the output shaft of the third electric control cylinder is fixedly connected to the first roller frame, the cylinder body of the third electric control cylinder is fixedly connected to the inner top wall of the housing, and the third electric control cylinder is signal-connected to the controller.

[0026] The beneficial effects of the basic scheme are: under the control of the controller, the feed roller and the paint roller will move vertically upward or downward; when the paint roller moves, it can make the board of different thicknesses come into contact with the paint roller to achieve the coating of the board; when the feed roller moves vertically, the distance between the feed roller and the paint roller will change during the movement, thereby controlling the thickness of the paint.

[0027] Furthermore, the bottom wall of the hollow part of the fixing block is hourglass-shaped, and the bottom of the fixing block has an opening with a sealing plug.

[0028] The beneficial effect of the basic solution is that when removing the paint, the sealing plug can be removed directly, which allows the paint to be removed completely and reduces the problem of paint remaining in the four corners and being inconvenient to remove.

[0029] Furthermore, the fixing block includes a paint collection block and an auxiliary movement part arranged sequentially from top to bottom; the hollow part of the fixing block is located at the paint collection block;

[0030] The auxiliary motion unit includes a support frame fixedly connected to the top of the paint collection block, an auxiliary roller rotatably connected to the support frame, and a hub motor for driving the auxiliary roller is installed inside the auxiliary roller.

[0031] The beneficial effects of the basic scheme are: on the one hand, the auxiliary roller can provide some support for the board, and on the other hand, the auxiliary roller can help the board move smoothly laterally and move out of the output frame. Attached Figure Description

[0036] The following detailed description illustrates the specific implementation method:

[0037] The reference numerals in the accompanying drawings include: housing 1, transport frame 2, support rod 3, second roller frame 4, conveyor roller 5, partition plate 6, conveying chamber 7, coating chamber 8, output frame 9, paint roller 10, first roller frame 11, paint inlet 12, third electric control cylinder 13, first electric control cylinder 14, third roller frame 15, positioning roller 16, thickness measuring assembly 17, pressure measuring cylinder 171, pressure sensor 172, piston 173, tension spring 174, piston rod 175, extrusion ball 176, first chute 18, first slider 19, top plate 20, electric telescopic rod 21, bottom plate 22, feed port 23, second chute 24, second slider 25, connecting block 26, second electric control cylinder 27, paint collection block 28, sealing plug 29, support frame 30, auxiliary roller 31, guide plate 32, material conveying port 33, and inlet 34.

[0038] Example 1

[0039] The basics are as follows: Figures 1-4 As shown: An automated control roller coating device includes a housing 1, a transport frame 2 and an output frame 9 respectively on both sides of the housing 1, a partition plate 6 is provided inside the housing 1, the top and bottom of the partition plate 6 are welded to the inner top wall and inner bottom wall of the housing 1 respectively, and the partition plate 6 has an opening, which divides the inside of the housing 1 into a transport chamber 7 and a roller coating chamber 8.

[0040] The conveying chamber 7 is equipped with a conveying assembly for conveying the sheet material, and the roller coating chamber 8 is equipped with a roller coating assembly for roller coating the sheet material. The roller coating assembly includes a feed roller and a paint roller 10. The diameter of the feed roller is smaller than that of the paint roller 10, and the distance between the feed roller and the paint roller 10 is the paint thickness. Both the feed roller and the paint roller 10 are embedded with hub motors for driving them. The hub motors are connected to a controller. The feed roller and the paint roller 10 rotate towards each other, and the paint roller 10 can contact the top of the sheet material. Both the feed roller and the paint roller 10 are equipped with a first roller frame 11. A support is welded to the end of the first roller frame 11 away from the feed roller and the paint roller 10. The support is welded to the inner top wall of the housing 1. The inner top wall of the roller coating chamber 8 is also provided with a paint inlet 12, which is located between the feed roller and the paint roller 10.

[0041] The roller coating chamber 8 is also equipped with a fixing component, which includes hollow fixing plates symmetrically arranged on both sides of the coating roller 10. A hollow fixing block is welded to the lower part of the fixing plate near the coating roller 10. The fixing block can be located at the bottom of the plate and is used to support the plate. A feed port 23 is opened at the end of the fixing plate near the coating roller 10. An inclined guide plate 32 is welded inside the hollow part of the fixing plate. The guide plate 32 is welded to the feed port 23. The end of the guide plate 32 near the feed port 23 is higher than the other end of the guide plate 32. The bottom end of the hollow part of the fixing plate is inclined in the opposite direction to the inclination of the guide plate 32. A conveying port 33 is opened on the side of the fixing plate near the fixing block. An inlet port 34 corresponding to the position of the conveying port 33 is opened on the side of the fixing block near the fixing plate. The hollow part of the fixing plate and the hollow part of the fixing block are connected through the conveying port 33 and the inlet port 34.

[0042] The specific implementation process is as follows: When coating the board, the board is first taken to the transport frame 2 and then placed from the transport frame 2 into the conveying chamber 7. Then the conveying component transports the board to the roller coating chamber 8. When the board is transported into the roller coating chamber 8, the board contacts the fixing component and the roller coating component.

[0043] First, the two sides of the board contact the fixed plate, and the board is located above the fixed block. The fixed block provides a certain support for the board. Then, the top of the board contacts the paint roller 10. When applying paint, the paint or other coatings first flow in from the paint inlet 12. Then, the paint contacts the feed roller and the paint roller 10 in sequence. At this time, both the feed roller and the paint roller 10 rotate inward. As a result, the paint on the feed roller and the paint roller 10 forms a V-shaped flow. Secondly, under the mutual rotation of the feed roller and the paint roller 10, the feed roller will limit the thickness of the flowing paint. At the same time, the paint roller 10 contacts the top of the board and realizes the paint operation on the top of the board.

[0044] When coating the board, the coating roller 10 applies a certain pressure to the board, which requires a certain support force to the bottom of the board, so that the coating can be firmly applied to the top of the board. Therefore, when the board is in the coating chamber 8 and is located on the top of the fixed block, the fixed block applies a certain support force to the board, so that the board can be coated with the coating relatively stably.

[0045] On the other hand, during the coating process, the coating is squeezed by the coating roller 10 above the board to ensure that the coating is applied evenly. Since the coating is mostly fluid, it flows to both sides of the board under the pressure of the coating roller 10. After flowing to both sides under pressure, the coating comes into contact with the fixed plates located on both sides of the board. Since the fixed plates are provided with inlets 23, the coating that overflows during the coating process comes into contact with the inlets 23. Then, guided by the guide plate 32 at the inlets 23, the coating flows to the hollow part of the fixed plate. Then, the coating flows to the bottom of the fixed plate by gravity. Since the bottom of the fixed plate is inclined and the hollow part of the fixed plate is connected to the hollow part of the fixed block through the feed port 33 and the inlet port 34, the coating flows into the hollow part of the fixed block to achieve material collection and storage.

[0046] Therefore, the design of the fixing components can support the board and thus assist the coating process. At the same time, it can collect the paint that overflows during the coating process, reducing material splashing and the problem of difficult paint waste cleaning later. The collected paint can also be reused after certain processing, further reducing material waste. During the coating process, the controller controls the start of each component to achieve the coating of the board. The controller also monitors the coating process in real time to adjust the coating process as needed, thereby achieving automated board coating.

[0047] Example 2

[0048] The difference from the above embodiments is that the conveying assembly includes a plurality of conveying rollers 5, each of which is embedded with a hub motor for driving the conveying roller 5. Each of the conveying rollers 5 is provided with a second roller frame 4, and a support rod 3 is welded to the other end of the second roller frame 4. The support rod 3 is welded to the bottom wall of the inner wall of the housing 1.

[0049] A positioning assembly is provided above the conveyor roller 5 closest to the partition plate 6. The positioning assembly includes a positioning roller 16, which has a hub motor embedded in it for driving the positioning roller 16. A third roller frame 15 is provided on the positioning roller 16. A first electric control cylinder 14 is bolted to the other end of the third roller frame 15. The output shaft of the first electric control cylinder 14 is bolted to the third roller frame 15. The cylinder body of the first electric control cylinder 14 is bolted to the top wall of the housing 1. Both the hub motor and the first electric control cylinder 14 are connected to the controller signal.

[0050] The specific implementation process is as follows: After the board is placed in the transport frame 2, the hub motor in the conveyor roller 5 is started by the controller, so the conveyor roller 5 rotates, and the board will be gradually conveyed to the coating chamber 8 for coating operation under the action of the rotating conveyor roller 5.

[0051] During the coating process, the controller can activate the first electric cylinder 14. When the first electric cylinder 14 is activated, the positioning roller 16 will move vertically downwards, and the positioning roller 16 will also contact the top of the board. This will help transport and stabilize the board, reducing the problem of uneven force on the board causing it to warp during coating due to the lever principle. This achieves stable transport of the board while assisting in the coating operation.

[0052] Example 3

[0053] The difference from the above embodiments is that the fixing plate includes a top plate 20, an electric telescopic rod 21 and a bottom plate 22 welded from top to bottom. A T-shaped first slider 19 is welded to the top of the top plate 20. A first groove 18 corresponding to the first slider 19 is opened in the inner top wall of the housing 1. The top plate 20 and the housing 1 slide laterally through the first slider 19 and the first groove 18. The length of the bottom plate 22 is greater than the length of the top plate 20, and the hollow part of the fixing plate is located inside the bottom plate 22.

[0054] A second electric control cylinder 27 is welded to both sides of the base plate 22 away from the plate material. The output shaft of the second electric control cylinder 27 is welded to the base plate 22. A connecting block 26 is welded to the cylinder body of the second electric control cylinder 27. A second slider 25 is welded to the side of the connecting block 26 away from the second electric control cylinder 27. The inner wall of the housing 1 is provided with a second sliding groove 24 corresponding to the position of the second slider 25. The connecting block 26 and the housing 1 are vertically slidingly engaged through the second slider 25 and the second sliding groove 24. The electric telescopic rod 21 and the second electric control cylinder 27 are both connected to the controller signal.

[0055] The specific implementation process is as follows: Since the width and thickness of the boards are not consistent, it is necessary to adjust the fixing components through the controller to achieve sufficient support for the boards;

[0056] When adjusting the width to fit the width of the board, the controller activates the second electric cylinder 27. As a result, the base plate 22 moves closer to or further away from the board under the action of the second electric cylinder 27, so that the base plate 22 can always be in contact with both sides of the board, thus allowing the overflowing paint to be collected more smoothly. At the same time, when the lateral width of the base plate 22 is adjusted, the lateral movement of the base plate 22 will not be affected because the top plate 20 is provided with the first slider 19 and slides laterally with the housing 1 through the first sliding groove 18.

[0057] When the height is adjusted to accommodate the thickness of the sheet material, the controller activates the electric telescopic rod 21, thereby enabling the base plate 22 to move vertically upwards or downwards. This ensures that the fixed block remains below the sheet material, thus supporting it. Furthermore, the design of the second slider 25 and the second slide groove 24 allows the base plate 22 to move smoothly vertically upwards or downwards.

[0058] Example 4

[0059] The difference from the above embodiments is that infrared sensors for measuring the width of the plate are provided on the inner sidewall of the transport frame 2, and the infrared sensors are connected to the controller signal.

[0060] The specific implementation process is as follows: After the board is put into the transport frame 2, the infrared sensor collects the width information of the board, and then the infrared sensor transmits the collected information to the controller. The controller receives the information and processes it. Then the controller performs pre-control and adjustment of the fixing components and makes the position of the base plate 22 relatively stable on both sides of the board.

[0061] Example 5

[0062] The difference from the above embodiment is that a thickness measuring component 17 is also provided in the conveying cavity 7. The thickness measuring component 17 includes a pressure measuring cylinder 171 disposed above the conveying roller 5. The top of the pressure measuring cylinder 171 is welded to the inner top wall of the housing 1. A pressure sensor 172 is bolted to the inner top wall of the pressure measuring cylinder 171. A piston 173 is slidably fitted inside the pressure measuring cylinder 171. A piston rod 175 is welded to the bottom of the piston 173. The piston rod 175 passes through the bottom of the pressure measuring cylinder 171 and extends to the outside of the pressure measuring cylinder 171. A compression ball 176 is welded to the end of the piston rod 175 away from the piston 173. The compression ball 176 can contact the plate. The pressure sensor 172 is signal-connected to the controller.

[0063] The piston 173 is also welded to the bottom with tension springs 174 located on both sides of the piston rod 175, and the other end of the tension springs 174 is welded to the inner bottom wall of the pressure measuring cylinder 171.

[0064] The specific implementation process is as follows: When the plate moves into the conveying chamber 7, the top of the plate contacts the extrusion ball 176. Then, the extrusion ball 176 is subjected to a certain amount of extrusion under the action of the plate. The piston rod 175 will move upward. The piston 173 moves upward during the vertical upward movement of the piston rod 175. As a result, the pressure inside the pressure measuring cylinder 171 changes. Then, the pressure sensor 172 inside the pressure measuring cylinder 171 will collect the pressure change value and transmit the pressure change value to the controller. The controller processes the data and calculates the plate thickness so as to facilitate the subsequent adjustment of the fixing components.

[0065] Meanwhile, because the extrusion ball 176 and piston 173 have a certain weight, when the surface of the board is not smooth and has certain grooves or patterns, the extrusion ball 176 falls down and contacts the grooves or patterns. At this time, the pressure value in the pressure measuring cylinder 171 also changes. The pressure value information is transmitted to the controller through the controller. The controller can monitor the position of the grooves and patterns on the board according to the different time intervals of the different pressure values. Then, the controller directly controls the fixed component and the roller coating component to change, so that the coating in the grooves and patterns is more uniform.

[0066] Example 6

[0067] The difference from the above embodiments is that the support is a third electric control cylinder 13, the output shaft of the third electric control cylinder 13 is fixedly connected to the first roller frame 11, the cylinder body of the third electric control cylinder 13 is fixedly connected to the inner top wall of the housing 1, and the third electric control cylinder 13 is connected to the controller signal.

[0068] The specific implementation process is as follows: Through the control of the controller, the third electric control cylinder 13 can be started accordingly. When the third electric control cylinder is started, the feeding roller and the paint roller 10 will move vertically upward or downward accordingly.

[0069] When the coating roller 10 moves, it can make the plates of different thicknesses come into contact with the coating roller 10, thereby achieving coating on the plates;

[0070] When the feed roller moves vertically, the distance between the feed roller and the paint roller 10 will change accordingly during the movement. As a result, the thickness of the paint can be controlled by the change in the distance between the two rollers, thereby achieving flexible selection of paint thickness.

[0071] Example 7

[0072] The difference from the above embodiment is that the bottom wall of the hollow part of the fixing block is hourglass-shaped, and the bottom of the fixing block is provided with an opening, and a sealing plug 29 is provided at the opening.

[0073] The specific implementation process is as follows: When the paint is guided to flow into the hollow part of the fixed block, because the bottom of the hollow part of the fixed block is hourglass-shaped, when the paint is taken out, the sealing plug 29 can be directly removed, so that the paint can be taken out and the problem of paint remaining in the four corners and being inconvenient to take out can be reduced.

[0074] Example 8

[0075] The difference from the above embodiment is that the fixing block includes a paint collection block 28 and an auxiliary movement part arranged sequentially from top to bottom; the hollow part of the fixing block is provided at the paint collection block 28;

[0076] The auxiliary motion unit includes a support frame 30 fixedly connected to the top of the paint collection block 28, an auxiliary roller 31 rotatably connected to the support frame 30, and a hub motor for driving the auxiliary roller 31 is provided inside the auxiliary roller 31.

[0077] The specific implementation process is as follows: When the board is on the fixed block, that is, above the auxiliary roller 31, the auxiliary roller 31 can provide a certain support for the board on the one hand, and on the other hand, the auxiliary roller 31 can assist the board to move smoothly laterally and move out from the output frame 9.
