Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spraying equipment, in particular to an organic coating spraying equipment. BACKGROUND

[0002] In industrial production, organic coating spraying is a key and widely used process, which is widely used in many fields such as automobile manufacturing, aerospace, electronic equipment, furniture decoration, etc. The traditional organic coating spraying operation is usually carried out in an open or semi-open environment. This operation mode has many disadvantages.

[0003] In an open environment, the coating is extremely easy to escape into the surrounding environment during the spraying process. This not only causes a lot of waste of coating, increases the production cost, but also poses a serious threat to the health of the operators. The harmful substances such as volatile organic compounds (VOCs) contained in the organic coating, if exposed to such an environment for a long time, the operators may have respiratory diseases, skin allergies and other health problems. At the same time, these escaped coatings will also pollute the surrounding environment and affect the quality of the ecological environment.

[0004] In addition, the traditional spraying equipment also has certain limitations in function. For example, during the spraying process, it is difficult to achieve all-around and uniform spraying for some complex-shaped products, especially the bottom and edge parts, which is prone to have dead angles, affecting the overall protection performance and aesthetics of the product. In order to avoid similar problems, most enterprises use mechanical arm spraying, but the cost of mechanical arm is high, and the surface will be corroded and the precision will be reduced in the long-term organic coating environment.

[0005] With the continuous development of industrial technology and the increasing demand for environmental protection, the market has put forward higher requirements for organic coating spraying equipment. It is of great practical significance to develop an organic coating spraying equipment that can provide a relatively independent and closed spraying environment, achieve all-around and uniform spraying, and has high flexibility and adaptability and low cost.

[0024] A conveying belt 102 is horizontally mounted at the inner bottom position of the spraying channel 1, and the conveying belt 102 can stably and continuously run to realize the conveying function of the workpiece. The spraying platform 103 is rotationally connected to the conveying belt 102 through a rotating connecting piece, which ensures that the spraying platform 103 can flexibly rotate on the conveying belt 102.

[0025] A special rotary driving device is arranged in the spraying platform 103, which can drive the spraying platform 103 to rotate during the transmission of the spraying platform 103 by the conveying belt 102, thereby meeting the demand for all-around and uniform spraying of organic paint.

[0028] An installation groove 1041 is formed in the spraying channel 1 and communicated with the inside of the spraying channel 1, which is communicated with the placing channel 104 and matched with the diameter of the feeding pipe 105. The feeding pipe 105 is communicated with the spraying assembly 2 through the installation groove 1041.

[0029] The other end of the feeding pipe 105 is connected to a paint bucket 107 through the placing channel 104 and the pipeline mounting block 106, and the paint bucket 107 is used for storing and delivering organic paint.

[0030] The spraying assembly 2 and the supplementary spraying assembly 3 are fixed on the inner wall of the spraying channel 1. The spraying assembly 2 is located above the spraying platform 103, and its main function is to comprehensively spray the material placed on the spraying platform 103 from the side and above. The supplementary spraying assembly 3 is arranged on the side of the spraying platform 103, which can supplement the spraying of the bottom missed area and the area that cannot be sprayed by the spraying assembly 2 during the spraying process, so as to ensure the spraying quality of the material. In addition, the spraying assembly 2 and the supplementary spraying assembly 3 are located on the moving path of the spraying platform 103, so that the material can pass through the spraying assembly 2 and the supplementary spraying assembly 3 in sequence during the movement of the spraying platform 103, and the complete spraying process is realized.

[0031] The spraying assembly 2 comprises a shell 201, which is hollow and arc-shaped, and the center of the outer wall of the shell 201 is fixed to the inner wall of the spraying channel 1. A liquid inlet 202 is formed in the shell 201, which is located near one end of the placing channel 104 and corresponds to the position of the installation groove 1041.

[0032] The organic paint enters the pipeline mounting block 106 and the placing channel 104 from the pipe groove 1061 through the feeding pipe 105, and then enters the inside of the spraying assembly 2 through the installation groove 1041 and the liquid inlet 202.

[0033] A sliding groove 208 is formed in the inner wall of the shell 201 and communicated with the inside of the shell 201, and a nozzle assembly 207 is slidably arranged in the sliding groove 208.

[0034] Two sliding blocks 205 are slidably connected to the inner wall of the shell 201, and a connecting rod 206 is hingedly connected to the opposite side of each of the two sliding blocks 205. A nozzle assembly 207 is hingedly connected between the two connecting rods 206, and is used for spraying materials.

[0035] The nozzle assembly 207 comprises an outer shell 2071, which is hollow inside. The two connecting rods 206 are hingedly connected to the two sides of the outer shell 2071. An installation hole 2078 is formed in the side of the outer shell 2071 close to the shell 201. The outer shell 2071 is slidably connected in the sliding groove 208 and communicates with the inside of the shell 201 through the installation hole 2078.

[0036] When the two sliding blocks 205 move close to each other, the nozzle assembly 207 is driven to move along the sliding groove 208 to the side of the spraying platform 103 through the transmission of the connecting rod 206. When the two sliding blocks 205 move away from each other, the nozzle assembly 207 is driven to move along the sliding groove 208 to the side away from the spraying platform 103. In this way, the height position of the nozzle assembly 207 can be flexibly adjusted to adapt to the spraying needs of materials of different heights, and the precision and adaptability of spraying are improved.

[0037] A slide rail 203 is fixed to the inner side wall of the shell 201. Two rollers 204 are slidably connected to the slide rail 203, and a linear drive is arranged in each of the two rollers 204 to drive the two rollers 204 to slide on the slide rail 203.

[0038] A high-pressure pipeline is installed between the liquid passage 202 and the installation hole 2078, and the high-pressure pipeline is located between the two rollers 204. When it is necessary to adjust the nozzle assembly 207 to move away from the part to be sprayed, the two rollers 204 move to the two ends of the shell 201, so that the high-pressure pipeline overlaps the part of the paint delivery line inside the shell 201. When it is necessary to adjust the nozzle assembly 207 to move away from the part to be sprayed, the two rollers 204 are started to reduce the overlapping part of the paint delivery line inside the shell 201, and the two rollers 204 can also prevent the high-pressure pipeline from winding while rotating in the shell 201.

[0039] The internal space of the shell 2071 is a liquid passage 2076, which is communicated with the inside of the shell 2071 through a mounting hole 2078, and a hollow connecting shaft 2072 is rotatably connected to the inner wall of the shell 2071, one end of the connecting shaft 2072 is provided with a through groove communicated with the liquid passage 2076, and the other end is provided with a motor 2077, the motor 2077 is fixed on the shell 2071, and the output end of the motor 2077 penetrates the shell 2071 and is fixed with the connecting shaft 2072 to drive the connecting shaft 2072 to rotate.

[0040] The outer wall of the connecting shaft 2072 is fixed with a spray head one 2073, the outer wall of the connecting shaft 2072 is provided with a through hole 2074 communicated with the inside, the through hole 2074 is communicated with a nozzle 2075 of the spray head one 2073, and the nozzle 2075 faces the spraying platform 103 for spraying the material.

[0041] The organic coating entering the liquid passage 2076 through the mounting hole 2078 flows into the inside of the connecting shaft 2072 through the through groove, then enters the spray head one 2073 through the through hole 2074, and finally is sprayed out from the nozzle 2075, so that the spraying operation on the material is realized, and when the motor 2077 drives the connecting shaft 2072 to rotate, the spray head one 2073 can be rotated, so that the spraying angle is changed, the spraying range is further expanded, and the spraying effect is improved.

[0042] The spray assembly 3 comprises a gas cylinder 301, the gas cylinder 301 is fixed to the outer wall of the spraying channel 1, the output end of the gas cylinder 301 penetrates the inner wall of the spraying channel 1 and is fixed with a support plate 302, and the support plate 302 is fixed with a spray head two 303.

[0043] When the bottom and edge of the material need to be supplemented and sprayed, the gas cylinder 301 is started, the output end of the gas cylinder 301 pushes the support plate 302 to move towards the material, so that the spray head two 303 reaches the appropriate supplement and spraying position, then the spray head two 303 sprays the coating, and the supplement and spraying work on the bottom and edge of the material is completed. After the supplement and spraying is completed, the gas cylinder 301 drives the support plate 302 and the spray head two 303 to return to the initial position, waiting for the next supplement and spraying task.

[0044] A spraying method of an organic coating spraying device: S1: When it is necessary to spray parts or mechanisms, first open the sealing baffle 101 close to one end of the spraying assembly 2, place the parts to be sprayed on the spraying platform 103, and seal the inside of the spraying channel 1 by closing the sealing baffle 101.

[0045] S2: Start the conveyor belt 102 to drive the spraying platform 103 and the part to be sprayed to move towards the spraying assembly 2, and stop the conveyor belt 102 when the spraying platform 103 and the part to be sprayed are directly below the spraying assembly 2.

[0046] S3: Start the rotating drive device inside the spraying platform 103 to drive the part to be sprayed to rotate, and start the nozzle 2075 and the paint bucket 107 during the rotation of the part to be sprayed. The organic paint inside the paint bucket 107 enters the liquid passage 2076 through the feed pipe 105 and the high-pressure pipe. The organic paint in the liquid passage 2076 flows into the connecting shaft 2072 through the passage, and then enters the spray head one 2073 through the through hole 2074, and finally is sprayed out from the nozzle 2075, realizing the spraying operation of the material. Moreover, when the motor 2077 drives the connecting shaft 2072 to rotate, it can drive the spray head one 2073 to rotate, thereby changing the spraying angle and avoiding the occurrence of spraying dead angles in the spraying area, and improving the spraying effect.

[0047] The height adjustment step of the spray head assembly 207: when it is necessary to change the distance between the nozzle 2075 and the surface of the part to be sprayed, start the sliding block 205. When the two sliding blocks 205 approach each other, the transmission action of the connecting rod 206 will drive the spray head assembly 207 to move along the sliding groove 208 to the side of the spraying platform 103. When the two sliding blocks 205 move away from each other, the spray head assembly 207 will move along the sliding groove 208 to the side away from the spraying platform 103. In this way, the distance between the spray head assembly 207 and the surface of the part to be sprayed is flexibly adjusted to adapt to the spraying needs of materials of different heights, and the precision and adaptability of spraying are improved.

[0048] Through the above method, the area at the bottom of the part cannot be sprayed by the spraying assembly 2, and the bottom and edge of the material need to be supplemented.

[0049] The high-pressure pipe adjustment step: when the spray head assembly 207 is adjusted to move away from the part to be sprayed, start the linear drive of the roller 204 to move the two rollers 204 to the two ends of the housing 201, thereby increasing the overlapping part of the high-pressure pipe inside the housing 201. When the spray head assembly 207 is adjusted to move close to the part to be sprayed, start the linear drive to move the two rollers 204, thereby reducing the overlapping part of the high-pressure pipe inside the housing 201, and preventing the high-pressure pipe from being wound when the roller 204 rotates.

[0050] S4: Start the conveyor belt 102 to drive the spraying platform 103 and the part to be sprayed to move towards the spraying assembly 2, and stop the conveyor belt 102 when the spraying platform 103 and the part to be sprayed are directly below the spraying assembly 2.

[0051] S5: the output end of the cylinder 301 pushes the support plate 302 to move towards the material, so that the second nozzle 303 reaches the appropriate position for supplementary spraying, and then the second nozzle 303 sprays paint to complete the supplementary spraying of the bottom and edges of the material. After the supplementary spraying is completed, the cylinder 301 drives the support plate 302 and the second nozzle 303 to return to the initial position, waiting for the next supplementary spraying task.

[0052] S6: after the surface paint of the part is cured, the sealing baffle 101 at one end of the supplementary spraying assembly 3 is opened, and the painted part is taken out.

[0053] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
