Description

Technical Field

[0001] This invention belongs to the field of spraying and conveying technology, specifically a conveying device for paint spraying. Background Technology

[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the spray to the surface of the object being coated. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.

[0003] The spraying conveyor line is mainly used for conveying parts in the workshop. It mainly uses a conveyor mechanism to transport parts through each necessary spraying equipment, and then uses the spraying equipment to spray the parts.

[0004] However, during the painting process, some oil vapors will spray onto the conveyor belt, causing paint to adhere to the conveyor belt. When new parts are placed on the conveyor belt, the paint on the conveyor belt will adhere to the parts in advance, thus affecting the painting quality of the parts. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a conveying device for paint spraying.

[0006] Includes a conveyor box; a placement box is installed on one side of the conveyor box; a spraying device is installed on the top of the conveyor box;

[0008] The conveying assembly includes a first mounting block and a second mounting block; the first mounting block is mounted on the surface of one of the conveyor belts; the second mounting block is mounted on the surface of the other conveyor belt; a cleaning block is fixedly connected to the opposite end face of the first mounting block and the second mounting block.

[0009] A conveying rod is slidably connected to the inner wall of the first mounting block, and one side of the conveying rod extends out of the first mounting block; the other side of the conveying rod extends to one side of the second mounting block and fits against the second mounting block; the conveying rod passes through the cleaning block and is slidably connected to the cleaning block.

[0010] A support rod is slidably connected inside the conveying rod, and the support rod passes through the second mounting block and is rotatably connected to the second mounting block; a stop block is fixedly connected to the side of the support rod away from the conveying rod, and the stop block is in contact with the end face of the second mounting block;

[0011] A first collection chamber is provided between the two conveyor rollers, and the first collection chamber is located between the two conveyor belts and is fixedly connected to the conveyor box by a connecting rod; a uniformly arranged nozzle is installed on the lower surface of the first collection chamber near one of the drive rollers, and the nozzle is connected to an external water source through a water pipe;

[0012] Two baffles are fixedly connected to one side of the conveying rod that extends out of the first mounting block; two guide rods are provided on the left side of the two transmission rollers, and the guide rods are trapezoidal; the guide rods are divided into two inclined areas and one flat area;

[0013] Both the upper surface of the guide rod above and the lower surface of the guide rod below are fixedly connected to connecting rods, and the other end of each connecting rod is fixedly connected to the placement box; the distance between the two guide rods is greater than the diameter of the conveyor rod and less than the diameter of the baffle; when the conveyor rod rotates with the conveyor belt to below the conveyor belt, the part between the two baffles on the conveyor rod will rotate into the space between the two guide rods;

[0014] A sponge layer is provided on the side of the first collection bin near another drive roller, and the upper surface of the sponge layer is in contact with the conveyor rod; a second collection bin is installed below the sponge layer.

[0015] Preferably, a first gear tooth is fixedly connected to the conveying rod between the two baffles; a second gear tooth is fixedly connected to the upper surface of the guide rod below, and the first gear tooth and the second gear tooth mesh with each other.

[0016] Preferably, the sponge layer is a conveyor belt type sponge layer; the sponge layer is driven by two rotating rollers, one of which is driven by a second motor;

[0017] The surface of the sponge layer is fixed with uniformly arranged arc-shaped layers, which are also sponge.

[0018] The sponge layer is rotatably connected to an extrusion rod on the side near the transmission roller, and the extrusion rod intersects with part of the sponge layer.

[0019] Preferably, each of the cleaning blocks has a convex groove, and the diameter of the groove opening is larger than the diameter of the conveying rod.

[0020] A scraper is fixedly connected to the cleaning block inside the convex groove;

[0021] The cleaning block has a drain hole on the side away from the conveyor belt, and the drain hole is connected to the convex groove.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The conveying equipment for paint spraying described in this invention can comprehensively scrape the surface of the conveyor rod after passing through the cleaning block, thereby improving the scraping effect of paint on the surface of the conveyor rod and preventing paint on the conveyor rod from adhering to the parts to be sprayed, thus affecting the spraying quality of the parts. At the same time, in conjunction with the nozzle spraying water, the conveyor rod can be rinsed, washing away some of the paint adhering to the conveyor rod, further improving the cleaning effect of the conveyor rod. Under the action of the sponge layer, the sponge layer can dry the water on the conveyor rod and further wipe the conveyor rod, further reducing the amount of paint residue and water content on the conveyor rod.

[0024] 2. In the paint spraying conveying device of the present invention, since the first gear and the second gear mesh with each other, when the part of the conveying rod located between the two baffles moves in the guide rod, the first gear will mesh with the second gear, thereby driving the conveying rod to rotate. This will pull the conveying rod to rotate while gradually pulling it out from the first mounting block and the cleaning block, thereby improving the scraping effect of the cleaning block on the conveying rod. At the same time, during the rotation of the conveying rod, the support rod also rotates with the conveying rod. Therefore, when the nozzle sprays water, the conveying rod can be cleaned more thoroughly. Subsequently, in conjunction with the scraping process of the cleaning block, the cleaning effect on the conveying rod can be further improved.

[0025] 3. In the paint spraying conveying device of the present invention, since the diameter of the convex groove is larger than the diameter of the conveying rod, when the conveying rod passes the cleaning block, the conveying rod will first enter the convex groove, and then the conveying rod will pass the scraper. When the conveying rod passes the scraper, the scraper can scrape the paint or water on the conveying rod into the convex groove for collection, and then fall into the second collection bin through the drain hole. When the cleaning block rotates with the conveyor belt to the top of the conveyor belt, the drain hole faces upward, thereby preventing the paint or water remaining in the convex groove from dripping from the drain hole.

Detailed Implementation

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 14 As shown, the present invention provides a conveying device for paint spraying;

[0045] Example 1

[0046] It includes a conveyor box 1; a placement box 11 is installed on one side of the conveyor box 1; and a spraying device 12 is installed on the top of the conveyor box 1.

[0047] Inside the conveyor box 1, there are rotatably connected transmission rollers 13 on both sides of the conveyor box 1, and the transmission rollers 13 are driven by the first motor 14; two conveyor belts 15 are rotatably connected to the two transmission rollers 13; and conveyor components are uniformly arranged and fixed to the two conveyor belts 15.

[0048] The conveying assembly includes a first mounting block 2 and a second mounting block 25; the first mounting block 2 is mounted on the surface of one of the conveyor belts 15; the second mounting block 25 is mounted on the surface of the other conveyor belt 15; a cleaning block 4 is fixedly connected to the opposite end face of the first mounting block 2 and the second mounting block 25.

[0049] A conveying rod 21 is slidably connected to the inner wall of the first mounting block 2, and one side of the conveying rod 21 extends out of the first mounting block 2; the other side of the conveying rod 21 extends to one side of the second mounting block 25 and fits against the second mounting block 25; the conveying rod 21 passes through the cleaning block 4 and is slidably connected to the cleaning block 4.

[0050] A support rod 22 is slidably connected inside the conveying rod 21, and the support rod 22 passes through the second mounting block 25 and is rotatably connected to the second mounting block 25; a stop block 23 is fixedly connected to the side of the support rod 22 away from the conveying rod 21, and the stop block 23 is in contact with the end face of the second mounting block 25.

[0051] A first collection chamber 16 is provided between the two conveyor rollers, and the first collection chamber 16 is located between the two conveyor belts 15 and is fixedly connected to the conveyor box 1 by a connecting rod; a uniformly arranged nozzle 17 is installed on the lower surface of the first collection chamber 16 near one of the drive rollers 13, and the nozzle 17 is connected to an external water source through a water pipe.

[0052] Two baffles 24 are fixedly connected to one side of the conveying rod 21 that extends out of the first mounting block 2; two guide rods 3 are provided on the left side of the two transmission rollers 13, and the guide rods 3 are trapezoidal; the guide rods 3 are divided into two inclined areas 31 and one flat area 32;

[0053] Both the upper surface of the upper guide rod 3 and the lower surface of the lower guide rod 3 are fixedly connected to a connecting rod 33, and the other end of the connecting rod 33 is fixedly connected to the placement box 11; the distance between the two guide rods 3 is greater than the diameter of the conveying rod 21 and less than the diameter of the baffle 24; when the conveying rod 21 rotates with the conveyor belt 15 to below the conveyor belt 15, the part between the two baffles 24 on the conveying rod 21 will rotate into the space between the two guide rods 3;

[0054] A sponge layer 5 is provided below the first collection bin 16 on the side near the other drive roller 13, and the upper surface of the sponge layer 5 is in contact with the conveyor rod 21; a second collection bin 18 is installed below the sponge layer 5;

[0055] When spraying parts, the operator first starts the spraying device 12 and the first motor 14. The first motor 14 drives the transmission roller 13 to rotate. The rotating transmission roller 13 drives the two conveyor belts 15 to rotate in a cycle. During the rotation of the conveyor belts 15, the first mounting block 2 and the second mounting block 25 will rotate. In turn, the first mounting block 2 and the second mounting block 25 will drive the conveyor rod 21 and the support rod 22 to rotate. Then, the parts to be sprayed are transferred to the conveyor rod 21. The evenly arranged conveyor rod 21 can support the parts. At the same time, the evenly arranged conveyor rod 21 will drive the parts to move during the rotation. When the parts move into the spraying device 12, the spraying device 12 can spray the parts. During the spraying process, excess paint will fall into the first collection bin 16. At the same time, the first collection bin 16 can prevent the paint from continuing to drip downwards. After the parts are sprayed, they will be moved out of the spraying device 12 along with the rotating conveyor assembly. Then, the sprayed parts are transferred out from the conveyor assembly.

[0056] Simultaneously, during the spraying process of the parts, some paint is sprayed onto the conveyor rod 21. When the conveyor rod 21 rotates to a position below the conveyor belt 15, the portion of the conveyor rod 21 extending beyond the first mounting block 2 rotates between the two guide rods 3. At the same time, two baffles 24 are located on both sides of the guide rods 3 and are used to restrict the position of the conveyor rod 21. During the rotation of the conveyor belt 15, the conveyor rod 21 moves within the two guide rods 3. As the conveyor rod 21 moves within the guide rods 3, because the guide rods 3 are trapezoidal, when the conveyor rod 21 passes through the inclined area 31 of the guide rods 3, and because the diameter of the baffles 24 is larger than the distance between the two guide rods 3, the guide rods 3 can pull the conveyor rod 21 as it moves with the conveyor belt 15. As the conveyor rod 21 gradually slides out from the first mounting block 2, it gradually passes through the cleaning block 4. During this process, the cleaning block 4 can scrape off the paint adhering to the conveyor rod 21. At the same time, when the conveyor rod 21 moves to the plane area 32 of the guide rod 3, it is no longer pulled out from the first mounting block 2. Instead, the conveyor rod 21 passes completely through the cleaning block 4 without completely sliding out of the first mounting block 2. During this process, the cleaning block 4 can thoroughly scrape the surface of the conveyor rod 21 after passing through it, thereby improving the paint removal effect on the surface of the conveyor rod 21 and preventing paint on the conveyor rod 21 from adhering to the parts to be painted, thus affecting the painting quality of the parts.

[0057] Meanwhile, since the support rod 22 is fixedly connected to the stop block 23 on the side close to the second mounting block 25, as the conveying rod 21 gradually slides out of the first mounting block 2, the support rod 22 gradually slides out of the conveying rod 21. When the conveying rod 21 moves to the plane area 32 of the guide rod 3, the support rod 22 is not completely pulled out of the conveying rod 21.

[0058] During the process of the conveyor rod 21 moving from the inclined area 31 of the guide rod 3 to the flat area 32 of the guide rod 3, the nozzle 17 sprays water downwards, and the water sprays onto the conveyor rod 21, thereby rinsing the conveyor rod 21 and washing away some of the paint adhering to the conveyor rod 21. Subsequently, with the scraping of the conveyor rod 21 by the cleaning block 4, the cleaning effect of the conveyor rod 21 can be further improved. At the same time, the water and paint after rinsing will fall into the second collection chamber 18.

[0059] As the conveyor belt 15 drives the conveyor rod 21 to rotate continuously, when the conveyor rod 21 moves from the flat area 32 to another inclined area 31, under the action of the guide rod 3, the conveyor rod 21 can be gradually pushed back into the first mounting block 2. At the same time, the conveyor rod 21 gradually approaches the sponge layer 5 and gradually contacts the upper surface of the sponge layer 5. When the conveyor rod 21 contacts the sponge layer 5, the sponge layer 5 can wipe the water off the conveyor rod 21 and further wipe the conveyor rod 21 to further reduce the amount of paint residue and water content on the conveyor rod 21.

[0060] When the conveyor rod 21 disengages from the guide rod 3, it returns to its initial position and then rotates cyclically with the conveyor belt 15. When the conveyor rod 21 rotates to the bottom of the conveyor belt 15 again, the above process is repeated.

[0061] Example 2

[0062] A first gear tooth 26 is fixedly connected to the conveying rod 21 between the two baffles 24; a second gear tooth 34 is fixedly connected to the upper surface of the guide rod 3 below, and the first gear tooth 26 and the second gear tooth 34 mesh with each other.

[0063] Since the first gear 26 and the second gear 34 mesh with each other, when the part of the conveying rod 21 located between the two baffles 24 moves within the guide rod 3, the first gear 26 will mesh with the second gear 34, thereby driving the conveying rod 21 to rotate. This will pull the conveying rod 21 to rotate while gradually pulling it out from the first mounting block 2 and the cleaning block 4, thus improving the scraping effect of the cleaning block 4 on the conveying rod 21. At the same time, during the rotation of the conveying rod 21, the support rod 22 also rotates with the conveying rod 21. Therefore, when the nozzle 17 sprays water, the conveying rod 21 can be cleaned more thoroughly. Subsequently, in conjunction with the scraping process of the cleaning block 4, the cleaning effect on the conveying rod 21 can be further improved.

[0064] Example 3

[0065] The sponge layer 5 is a conveyor belt type sponge layer 5; the sponge layer 5 is driven by two rotating rollers 51, one of which is driven by a second motor 52.

[0066] The surface of the sponge layer 5 is fixed with uniformly arranged arc-shaped layers 53, and the arc-shaped layers 53 are also sponge.

[0067] The sponge layer 5 is rotatably connected to the side near the transmission roller 13 with an extrusion rod 54, and the extrusion rod 54 intersects with part of the sponge layer 5.

[0068] When the spraying device 12 is started, the second motor 52 is also started. During the rotation of the second motor 52, the sponge layer 5 can be driven to rotate. During the rotation of the sponge layer 5, the conveyor rod 21 also rotates, so that the conveyor rod 21 can make more comprehensive contact with the sponge layer 5, thereby further improving the wiping effect of the conveyor rod 21 and reducing the water and paint content on the conveyor rod 21. Since the sponge layer 5 has uniformly arranged arc-shaped layers 53 fixed on it, when the arc-shaped layers 53 come into contact with the conveyor rod 21, they can be squeezed, thereby deforming the arc-shaped layers 53. During this process, the wiping force between the arc-shaped layers 53 and the conveyor rod 21 can be increased, thereby further wiping the conveyor rod 21 and reducing the water and paint content on the conveyor rod 21. When the rotating sponge layer 5 passes the squeezing rod 54, the squeezing rod 54 will squeeze the sponge layer 5, thereby squeezing out the water in the sponge layer 5 and preventing the sponge layer 5 from having too much water and being unable to absorb the water on the conveyor rod 21.

[0069] Example 4

[0070] Each of the cleaning blocks 4 has a convex groove 41, and the diameter of the groove opening of the convex groove 41 is larger than the diameter of the conveying rod 21.

[0071] A scraper 42 is fixedly connected to the cleaning block 4 inside the convex groove 41.

[0072] The cleaning block 4 has a drain hole 43 on the side away from the conveyor belt 15, and the drain hole 43 is connected to the convex groove 41.

[0073] Since the diameter of the groove 41 is larger than the diameter of the conveyor rod 21, when the conveyor rod 21 passes the cleaning block 4, it will first enter the groove 41. Then the conveyor rod 21 will pass the scraper 42. When the conveyor rod 21 passes the scraper 42, the scraper 42 can scrape the paint or water on the conveyor rod 21 into the groove 41 for collection. Then it will fall into the second collection chamber 18 through the drain hole 43. When the cleaning block 4 rotates with the conveyor belt 15 to the top of the conveyor belt 15, the drain hole 43 will face upward, thus preventing the paint or water remaining in the groove 41 from dripping from the drain hole 43.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
