DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all.

[0037] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figure 1-Figure 3 and Figure 7 As shown, a panel spraying device for wardrobe processing includes a fixing frame 100, a plurality of rollers 110, a plurality of chains 112, a spraying mechanism 200 and a drying mechanism 300.

[0040] The plurality of rollers 110 are rotatably connected to the fixed frame 100, and the plurality of rollers 110 are used to convey the plate, and two sprocket wheels 111 are installed on each roller 110. The chain 112 is sleeved on the two sprocket wheels 111, and the plurality of chains 112 are used to connect two adjacent rollers 110, so that the plurality of rollers 110 rotate synchronously.

[0041] One end of one of the rollers 110 extends outside the fixed frame 100, and a first bevel gear 113 is installed on one end of the roller 110 outside the fixed frame 100. Two motors 120 are installed on the fixed frame 100, and the power output shafts of the two motors 120 are fixedly connected to the two ends of the same roller 110 respectively.

[0042] Specifically, when the two motors 120 rotate simultaneously, one of the rollers 110 is driven to rotate, and then the remaining rollers 110 are driven to rotate via the sprocket 111 and the chain 112 , thereby facilitating the conveyance of the plate through the multiple rollers 110 .

[0043] The spraying mechanism 200 includes a first mounting frame 201, a spraying assembly 210 and a linkage assembly 220. The first mounting frame 201 is fixedly connected to the fixing frame 100. The spraying assembly 210 is mounted on the first mounting frame 201. The spraying assembly 210 is used to spray water paint on the plate. The spraying assembly 210 includes a plurality of spray heads 215. The linkage assembly 220 is mounted on the first mounting frame 201.

[0044] The drying mechanism 300 includes a second mounting frame 301 , a plurality of mounting rods 311 , and a plurality of blowing fan blades 312 .

[0045] The second mounting frame 301 is fixedly connected to the fixing frame 100 ; the plurality of mounting rods 311 are rotatably connected to the second mounting frame 301 ; and the plurality of blowing fan blades 312 are respectively mounted on the portion of the mounting rods 311 located inside the second mounting frame 301 .

[0046] Among them, when the motor 120 drives the multiple rollers 110 to rotate, the first bevel gear 113 on the roller 110 will drive the multiple nozzles 215 to move through the linkage assembly 220, thereby increasing the spraying range of the nozzle 215, and the first bevel gear 113 will also drive the multiple mounting rods 311 to rotate through the linkage assembly 220, thereby driving the multiple blowing fan blades 312 to rotate and blow air downward, thereby accelerating the drying of the paint layer on the plate.

[0047] like Figure 4As shown, the spraying mechanism 200 also includes a horizontal plate 202, two hinged plates 203, a vertical plate 204, a spring 205 and a through slot 206. The horizontal plate 202 has multiple nozzles 215 that are installed on the horizontal plate 202; one end of the two hinged plates 203 is hinged to the horizontal plate 202, and the other end of the two hinged plates 203 is hinged to the first mounting frame 201; one end of the spring 205 is fixedly connected to the first mounting frame 201, and the other end of the spring 205 is fixedly connected to the vertical plate 204; the through slot 206 is opened on the side of the first mounting frame 201 away from the spring 205.

[0048] Specifically, by pushing the horizontal plate 202 toward the direction close to the spring 205 , the spring 205 will be compressed. When the horizontal plate 202 is no longer pushed, the rebound force of the spring 205 will push the vertical plate 204 to move, thereby pushing the horizontal plate 202 to move.

[0049] like Figure 5 and Figure 6 As shown, the spraying assembly 210 further includes a barrel 211 , a pump body 213 , a connecting pipe 214 , a sensor 216 and an agitator 217 .

[0050] A feed hopper 212 is installed on the top surface of the cylinder 211, and the cylinder 211 is installed on the top surface of the first mounting frame 201; the pump body 213 is installed on the top surface of the first mounting frame 201, and the liquid extraction tube of the pump body 213 is fixedly connected and communicated with the cylinder 211; the connecting pipe 214 is connected to multiple nozzles 215, and the connecting pipe 214 is fixedly connected and communicated with the infusion tube of the pump body 213, and the infusion tube of the pump body 213 is a hose.

[0051] The sensor 216 is installed on the horizontal plate 202, and the sensor 216 is electrically connected to the control switch of the pump body 213. When the sensor 216 detects that there is a plate underneath, the sensor 216 will start the pump body 213 through the control switch of the pump body 213; when the sensor 216 does not detect that there is a plate underneath, the sensor 216 will turn off the pump body 213 through the control switch of the pump body 213.

[0052] The agitator 217 is used to stir the water paint in the cylinder 211; the agitator 217 includes a rotating rod 2171, a plurality of stirring rods 2172, a scraper 2173 and a fourth bevel gear 2174. The rotating rod 2171 is rotatably connected to the cylinder 211, and one end of the rotating rod 2171 extends outside the cylinder 211; the plurality of stirring rods 2172 are all mounted on the portion of the rotating rod 2171 located inside the cylinder 211; the fourth bevel gear 2174 is fixedly connected to one end of the rotating rod 2171 located outside the cylinder 211. The scraper 2173 is located inside the cylinder 211 and contacts the inner wall of the cylinder 211, and the scraper 2173 is fixedly connected to the plurality of stirring rods 2172.

[0053] Specifically, when the rotating rod 2171 rotates, it will drive the multiple stirring rods 2172 to rotate and stir the water paint in the cylinder 211, thereby avoiding stratification and segregation of the water paint; when the plate is under the sensor 216, the sensor 216 will start the pump body 213 through the control switch of the pump body 213, so that the pump body 213 will transport the water paint in the cylinder 211 to the connecting pipe 214, and then the multiple nozzles 215 will spray the water paint onto the plate.

[0054] like Figure 4 and Figure 5 As shown, the linkage assembly 220 includes two mounting blocks 221 , a vertical rod 222 , a cam 223 , a second bevel gear 224 , a third bevel gear 225 , an extension rod 226 and a large pulley 227 .

[0055] The two mounting blocks 221 are both mounted on the first mounting frame 201 ; the vertical rod 222 passes through the two mounting blocks 221 and is rotatably connected to the mounting blocks 221 .

[0056] The cam 223 is fixedly sleeved on the vertical rod 222. When the cam 223 rotates, it will penetrate the through slot 206 and push the horizontal plate 202 to move. The second bevel gear 224 is fixedly connected to the lower end of the vertical rod 222, and the second bevel gear 224 is meshed with the first bevel gear 113; the third bevel gear 225 is fixedly connected to the upper end of the vertical rod 222, and the third bevel gear 225 is meshed with the fourth bevel gear 2174; the extension rod 226 is fixedly connected to the third bevel gear 225; the large pulley 227 is fixedly sleeved on the extension rod 226.

[0057] Specifically, when the first bevel gear 113 rotates, it will mesh and drive the second bevel gear 224 to rotate, thereby driving the vertical rod 222 to rotate, and then driving the third bevel gear 225 and the cam 223 to rotate. When the vertical rod 222 rotates, it will also drive the extension rod 226 and the large pulley 227 to rotate.

[0058] like Figure 1 , Figure 2 and Figure 8 As shown, the drying mechanism 300 further includes two paint baking lamps 302 , a plurality of small pulleys 313 , a plurality of first transmission belts 314 and a second transmission belt 315 .

[0059] The two paint lamps 302 are both installed on the inner wall of the second mounting frame 301; two small pulleys 313 are installed on each mounting rod 311 of the multiple small pulleys 313; multiple first transmission belts 314 are sleeved on two adjacent small pulleys 313 with the same height, and the multiple first transmission belts 314 are used to make the multiple mounting rods 311 rotate synchronously; the second transmission belt 315 is sleeved on the small pulley 313 and the large pulley 227.

[0060] Specifically, when the large pulley 227 rotates, it will drive a small pulley 313 to rotate through the second transmission belt 315, and then drive a mounting rod 311 to rotate, and then drive multiple mounting rods 311 to rotate through multiple small pulleys 313 and the first transmission belt 314, and then the multiple mounting rods 311 drive multiple fan blades 312 to rotate; the diameter of the large pulley 227 is much larger than the diameter of the small pulley 313. When the large pulley 227 rotates one circle, the small pulley 313 can rotate more than ten circles.

[0061] Working principle: When the board spraying equipment for wardrobe processing is used, the board to be sprayed is placed on the roller 110 close to the motor 120, and then the two motors 120 are started, so that the power output shafts of the two motors 120 drive one roller 110 to rotate at the same time, and then drive multiple rollers 110 to rotate at the same time through multiple sprockets 111 and multiple chains 112. When multiple rollers 110 rotate, the second bevel gear 224 is driven to rotate through the first bevel gear 113, and then the vertical rod 222 is driven to rotate. The third bevel gear 225 and the cam 223 will rotate, and the rotating third bevel gear 225 will mesh and drive the fourth bevel gear 2174 to rotate, and then drive the rotating rod 2171 to rotate, and then the water paint in the cylinder 211 is stirred by multiple stirring rods 2172, so as to avoid the stratification and segregation of the water paint, and when the stirring rod 2172 rotates, it will also drive the scraper 2173 to rotate, so that the scraper 2173 cleans the inner wall of the cylinder 211 to avoid the water paint adhering to the inner wall of the cylinder 211.

[0062] As the multiple rollers 110 rotate, the plate will be driven to move. When the sensor 216 detects that there is a plate below, the sensor 216 will start the pump body 213 through the control switch of the pump body 213, so that the pump body 213 can transport the water paint in the cylinder 211 to the connecting pipe 214, and then the multiple nozzles 215 will spray the water paint on the plate. When the rollers 110 rotate, the vertical rod 222 and the cam 223 will also rotate, and the rotating cam 223 will move the horizontal plate 202, and the rotating cam 223 cooperates with the spring 205 and the vertical plate 204 to make the horizontal plate 202 reciprocate, thereby driving the multiple nozzles 215 to reciprocate, thereby increasing the spraying range of the nozzles 215.

[0063] As the multiple rollers 110 rotate, the plate sprayed with paint will be driven into the second fixing frame 100, and the paint lamp 302 in the second fixing frame 100 will accelerate the drying speed of the paint on the plate.

[0064] As the roller 110 rotates, the large pulley 227 is driven to rotate through the first bevel gear 113, the second bevel gear 224, the vertical rod 222 and the extension rod 226, and then a small pulley 313 is driven to rotate through the second transmission belt 315, and then a mounting rod 311 is driven to rotate, and then multiple mounting rods 311 are driven to rotate through multiple small pulleys 313 and the first transmission belt 314, and then multiple mounting rods 311 drive multiple blowing fan blades 312 to rotate, and the wind blown by the blowing fan blades 312 will also accelerate the drying speed of the paint on the plate.

[0065] Among them, when the roller 110 rotates, the linkage assembly 220 can drive multiple components such as the agitator 217, the nozzle 215, the mounting rod 311, and the blowing fan blades 312 to work together, thereby greatly improving the work efficiency. Compared with each component requiring an independent power source to drive, the design of the linkage assembly 220 significantly reduces energy consumption and waste.

[0066] Example 2

[0067] like Figure 1 and Fig. 9 As shown, while other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that the board spraying equipment for wardrobe processing also includes a sorting mechanism 400, and the sorting mechanism 400 includes a conveyor 401, a groove 402, a third mounting frame 403 and a board spraying quality detection unit.

[0068] The conveyor 401 is located on a side of the fixed frame 100 away from the first mounting frame 201. The conveyor 401 is used to receive a plurality of rollers 110 to transport the sprayed plates, and the conveyor 401 can drive the plates to move; the groove 402 is set on a side of the conveyor 401 close to the fixed frame 100, and the groove 402 can lower the height of one side of the conveyor 401 so that the rollers 110 can transport the plates to the conveyor 401 smoothly; the third mounting frame 403 is installed on the top surface of the conveyor 401.

[0069] The plate spraying quality detection unit is used to perform quality detection on the plates on the conveyor 401 and control the running direction of the conveyor 401 according to the quality detection result.

[0070] The plate spraying quality detection unit includes a data acquisition module, a data processing module and a control module.

[0071] The data acquisition module is used to collect the coating thickness at several points on the plate;

[0072] The data processing module is used to receive the coating thickness data sent from the data acquisition module, calculate the spraying quality index of the coating thickness data through a preset algorithm, compare the spraying quality index with a preset value, and generate a first adjustment instruction or a second adjustment instruction according to the comparison result;

[0073] The control module is used to generate a first control instruction or a second control instruction according to the first adjustment instruction or the second adjustment instruction, wherein the first control instruction and the second control instruction are to control the conveyor 401 to convey the plate clockwise or counterclockwise, respectively.

[0074] The plate spraying quality detection unit detects and controls the running direction of the conveyor 401, including the following steps:

[0075] Step S1: The data processing module receives the preset value set by the user and marks the preset value as Q th ;

[0076] Step S2, the data acquisition module collects the coating thickness at several points of the plate, and sends the coating thickness values ​​at the several points to the data processing module, wherein the coating thickness of the plate can be measured by a coating thickness gauge, and the thickness gauge can be installed on the inner bottom surface of the third mounting frame 403;

[0077] Step S3: The data processing module receives the coating thickness data, calculates the spraying quality index through a preset algorithm, and then marks the spraying quality index as Q. sp , Q sp With Q th For comparison,

[0078] If Q sp ≤Q th , the plate spraying quality is considered qualified, and the first adjustment instruction is generated;

[0079] If Q sp >Q th , the plate spraying quality is considered unqualified, and a second adjustment instruction is generated;

[0080] Step S31: The data processing module sends the first adjustment instruction or the second adjustment instruction to the processing module;

[0081] Step S4, the control module generates a first control instruction or a second control instruction according to the first adjustment instruction or the second adjustment instruction, wherein the first control instruction is to control the conveyor 401 to run clockwise so that the conveyor conveys the plate in a clockwise direction; the second control instruction is to control the conveyor 401 to run counterclockwise so that the conveyor conveys the plate in a counterclockwise direction.

[0082] In step S3, the preset algorithm for calculating the spraying quality index is:

[0083]

[0084] In the formula, Q sp Indicates the plate spraying quality evaluation index;

[0085] h(x, y) represents the coating thickness at position (x, y) on the plate;

[0086] Indicates the average coating thickness;

[0087] σ h Indicates the standard deviation of coating thickness, which is used to measure the uniformity of coating thickness;

[0088] A represents the area of ​​the plate;

[0089] α and β represent weight coefficients, which are used to adjust the importance of different factors in quality assessment;

[0090] ∈ is a small positive number that ensures the mathematical stability of the formula.

[0091] The formula consists of two parts. The first part measures the deviation of coating thickness from the average thickness, and the second part measures the uniformity of the coating. By weighted summing these two parts, an index for comprehensive evaluation of spraying quality can be obtained.

[0092] In the above formula, α and β are obtained as follows: First, according to the specific application scenario and previous experience, the values ​​of α and β can be preliminarily set. If it is considered that the thickness uniformity of the coating is more important than the average thickness deviation, a larger value can be given to α and a smaller value can be given to β.

[0093] Then optimize the values ​​of α and β through experiments or simulations, specifically by setting different combinations of α and β and calculating the corresponding Q sp The value is calculated and compared with the actual spraying quality, and then the best combination of α and β is found through iteration and adjustment to make Q sp Can reflect the actual spraying quality.

[0094] If there is already a lot of historical data, the historical data includes Q at different α and β values sp If we can use the data of actual spraying quality, we can determine the optimal α and β values ​​through data analysis. For example, we can use regression analysis, neural network or other machine learning algorithms to establish Q sp The relationship between the actual spraying quality and find the optimal weight coefficient.

[0095] By setting up a plate spraying quality inspection unit to sort the sprayed plates, it is ensured that only plates with qualified spraying quality can enter the next processing procedure, which is conducive to improving the overall quality of the final product. And by timely discovering and sorting out unqualified plates, it avoids wasting more time and resources in handling unqualified products in subsequent processes, which is convenient for reducing production costs and improving production efficiency.

[0096] Example 3

[0097] like Figure 1-Figure 9 As shown, a spraying method of a board spraying device for wardrobe processing comprises the following steps:

[0098] Step 1: Place the plate on the roller 110 close to the motor 120, start the two motors 120, and make the two motors 120 drive one roller 110 to rotate, and then drive multiple rollers 110 to rotate simultaneously through multiple chains 112, so as to transport the plate toward the conveyor 401;

[0099] Step 2, when the roller 110 rotates, the second bevel gear 224 will be driven to rotate through the first bevel gear 113, and then the vertical rod 222 will be driven to rotate, and then the third bevel gear 225 and the cam 223 will be driven to rotate, and the rotating third bevel gear 225 will mesh and drive the fourth bevel gear 2174 to rotate, and then the rotating rod 2171 will be driven to rotate, and then the water paint in the cylinder 211 will be stirred through the multiple stirring rods 2172, so as to avoid the stratification and segregation of the water paint, and when the stirring rod 2172 rotates, it will also drive the scraper 2173 to rotate, so that the scraper 2173 cleans the inner wall of the cylinder 211, and prevents the water paint from adhering to the inner wall of the cylinder 211;

[0100] Step 3: When the sensor 216 detects that there is a plate below, the pump body 213 is started, so that the pump body 213 transfers the water paint in the cylinder 211 to the connecting pipe 214, and then the water paint is sprayed onto the plate through the multiple nozzles 215. When the roller 110 rotates, the cam 223 in the linkage assembly 220 pushes the horizontal plate 202 and the multiple nozzles 215 to move, and the horizontal plate 202 and the multiple nozzles 215 move back and forth under the cooperation of the spring 205 and the vertical plate 204, thereby increasing the spraying range of the nozzles 215.

[0101] Step 4: After the spraying is completed, the plate will enter the second mounting frame 301 under the operation of the roller 110, and the paint lamp 302 will irradiate the plate to accelerate the drying of the paint on the plate. As the roller 110 rotates, the large pulley 227 will be driven to rotate through the first bevel gear 113, the second bevel gear 224, the vertical rod 222 and the extension rod 226, and then a small pulley 313 will be driven to rotate through the second transmission belt 315, and then a mounting rod 311 will be driven to rotate, and then multiple mounting rods 311 will be driven to rotate through multiple small pulleys 313 and the first transmission belt 314, and then multiple mounting rods 311 will drive multiple blowing fan blades 312 to rotate, and the wind blown by the blowing fan blades 312 will also accelerate the drying speed of the paint on the plate;

[0102] Step 5: When the plate is conveyed to the conveyor 401 via the roller 110, the plate spraying quality detection unit will perform quality detection on the plate, and control the running direction of the conveyor 401 according to the quality detection result, and sort the plate according to the spraying quality of the plate.
