Description

Technical Field

[0001] The invention relates to the technical field of blade processing, and in particular discloses a uniform spraying device for blade coating. Background Art

[0002] Carbide blades are an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. They have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. During the processing of carbide blades, a layer of coating, such as Teflon coating, will be sprayed on their surface. The use of coating technology can effectively improve the service life of the blades, enable the blades to obtain excellent comprehensive mechanical properties, and greatly improve the machining efficiency and product manufacturing accuracy. In order to improve the coating performance in the prior art, it is necessary not only to spray the front and back sides of the blades, but also to apply multiple layers of coating on the front and back sides of the blades. At this time, the turning structure and the spraying structure are used in combination. However, the reciprocating turning of the blades, waiting for drying, and spraying treatment requires a lot of waiting time, which affects the coating spraying efficiency of the blades.

[0003] In order to solve the problem that affects the spraying efficiency, a coating spraying machine on the market can solve certain of the above-mentioned problems by quickly drying the coating. For example, the invention patent with publication number CN118142783B discloses an automatic blade coating spraying machine field, and particularly relates to an automatic blade coating spraying machine, including a workbench and a spraying cabin, etc., an electric horizontal slider transfers the blade in the V-shaped holder to the spraying cabin, and a spraying mechanism sprays the coating on the surface of the blade in the V-shaped holder. At the same time, the insulation lamp cooperates with the drying lamp to quickly dry the coating on the blade surface inside the spraying cabin, and the blade is flipped at a small angle through the V-shaped holder to complete the flipping work, and the V-shaped holder is also provided with an exhaust nozzle to provide buffering for the flipped blade. The exhaust nozzle can also remove excess paint in time to avoid excess spray and outwardly sputtered spray from rising up and covering the drying lamp and the insulation lamp, thereby solving the technical problems that the reciprocating flipping and spraying of the blade requires a lot of waiting time, resulting in low blade coating spraying efficiency and the blade coating is prone to more friction loss.

[0004] Based on the above search, combined with the prior art, it is found that the above-mentioned blade coating sprayer uses a drying lamp to quickly dry the blade surface coating, uses a V-shaped holder to turn the blade at a small angle, and removes excess coating through an exhaust nozzle to reduce waiting time and improve spraying efficiency. However, in order to improve the composite efficiency between multiple layers of coating, the prior art does not completely dry the coating. When turning the blade over, the blade will inevitably come into contact with the V-shaped holder. At this time, hard contact damage will occur on the coating on the blade surface at the moment of contact, affecting the spraying efficiency. Moreover, in the process of removing the coating through the exhaust nozzle, a certain negative pressure will be generated between the exhaust nozzle and the blade surface. In a negative pressure environment, the coating is also easily peeled off the blade, which will further affect the spraying efficiency. Therefore, it is urgent to propose a uniform spraying device for blade coating to improve the above problems. Summary of the invention

[0016] In summary, after adopting the above structure, the present invention has the following advantages compared with the prior art:

[0017] 1. By using the above-mentioned first motor, workbench and inner support clamp, the blade body can be mounted on the inner support clamp and clamped in the clamping groove, which is convenient for installing and positioning the blade body, ensuring the stability of the blade body during spraying, and realizing the function of facilitating the disassembly of the blade body. The workbench can be driven to rotate in a cycle of 180 degrees under the action of the first motor, which is convenient for driving the two inner support clamps to perform position exchange processing, thereby realizing the functions of material discharge and material collection before and after the blade body is sprayed.

[0018] 2. The above-mentioned internal support fixture, rotating circle, spraying assembly, rotating assembly, nozzle and nozzle can be used to drive the driving gear to rotate under the action of the second motor in the rotating assembly, and the first gear ring, the second gear ring and the third gear ring are driven to rotate synchronously by meshing, and the connecting frame, rotating circle, nozzle and nozzle are driven to rotate. The mounting shaft, the internal support fixture and the blade body are also driven to rotate under the meshing action of the third gear ring and the pinion. When the liquid inlet hole is connected with the arc-shaped material frame, the paint is sprayed along the two nozzles and the two nozzles on the front and back surfaces of the rotating blade body, thereby achieving a uniform spraying effect. As the rotating circle continues to rotate, the next liquid inlet hole is connected with the arc-shaped material frame. At this time, the paint can be sprayed on the front and back surfaces of the rotating blade body again. The above process is repeated to achieve a uniform and multiple intermittent spraying effect on the front and back surfaces of the blade body. There is no need to turn the blade body over for spraying, and there will be no contact with the sprayed surface of the blade body during the spraying process, thereby avoiding affecting the spraying efficiency.

[0019] 3. By using the above-mentioned rotating circle, drying lamp, spraying assembly and rotating assembly, during the rotation of the rotating assembly, the liquid inlet hole on the rotating circle will form an intermittent connection with the spraying assembly, which will cause the spraying assembly to produce an intermittent non-spraying phenomenon. Therefore, during the interval time period between the first spraying and the second spraying, during the interval time period between the second spraying and the third spraying, and after the third spraying, the drying lamp is used to dry the paint on the front and back sides of the blade body to a certain extent, thereby improving the adhesion efficiency of the paint, reducing the interval time between multiple spraying, and improving the working efficiency of the entire device.

[0020] 4. By using the above-mentioned spray assembly, opening and closing plate and reflux pipe, when the spray assembly does not spray, the paint will be squeezed into the arc-shaped material frame due to the continuous operation of the spray assembly. At this time, the pressure in the arc-shaped material frame increases, forcing the opening and closing plate to open, so that part of the paint flows back into the paint barrel along the reflux hole and the reflux pipe, avoiding the problem of damage to the sealing ring caused by the increase in pressure in the arc-shaped material frame, preventing the effect of paint leakage, and making the entire spraying process without the need to shut down the spray assembly.

[0021] 5. By using the above-mentioned workbench, inner support clamp, arc baffle and cleaning scraper, the arc baffle can be used to protect the spraying area during the spraying operation to prevent the paint from spreading. The arc baffle and the cleaning scraper can also be driven to rotate simultaneously when the workbench rotates, and the cleaning scraper can be used to clean the drying lamp to prevent the paint from adhering to the drying lamp and affecting its normal operation.

[0022] 6. The above stirring assembly can drive the transmission gear to rotate synchronously during the working process of the rotating assembly, and drive the stirring blades to rotate in the paint barrel to ensure uniform mixing of the paint. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Next, the user draws out the paint in the paint barrel 1201 through the extraction pump 1202 and the extraction pipe in the spray assembly 12, and discharges the paint into the arc-shaped material frame 1206 along the discharge pipe 1203, and then drives the driving gear 1404 to rotate through the second motor 1403 in the rotating assembly 14, and drives the first gear ring 1402, the second gear ring 1406 and the third gear ring 1408 to rotate synchronously in a meshing manner, drives the connecting frame 1409, the rotating circle 8, the spray pipe 16 and the nozzle 17 to rotate, and also drives the installation under the meshing action of the third gear ring 1408 and the pinion 1407. The shaft 19, the inner support fixture 6 and the blade body 11 rotate, and when the liquid inlet hole 18 is connected with the arc-shaped material frame 1206, the paint is sprayed on the front and back surfaces of the rotating blade body 11 along the two nozzles 16 and the two nozzles 17, so that the surface of the blade body 11 is evenly sprayed. As the rotating circle 8 continues to rotate, the next liquid inlet hole 18 is connected with the arc-shaped material frame 1206, and the paint can be sprayed on the front and back surfaces of the rotating blade body 11 again. The above process is repeated, so that the front and back surfaces of the blade body 11 are evenly and repeatedly sprayed.

[0048] Moreover, during the rotation of the rotating component 14, the liquid inlet 18 on the rotating circle 8 will be intermittently connected with the spraying component 12, which will cause the spraying component 12 to intermittently not spray. Therefore, in the interval time between the first spraying and the second spraying, in the interval time between the second spraying and the third spraying, and after the third spraying, the paint on the front and back sides of the blade body 11 is dried by the drying lamp 9. When the spraying component 12 does not spray, due to the continuous spraying of the spraying component 12 The paint will be squeezed into the arc-shaped material frame 1206 during the continuous operation. At this time, the pressure in the arc-shaped material frame 1206 increases, forcing the opening and closing plate 1209 to open, so that part of the paint flows back into the paint barrel 1201 along the reflux hole 1210 and the reflux pipe 1204. After the liquid inlet hole 18 is connected with the arc-shaped material frame 1206, the pressure in the arc-shaped material frame 1206 gradually tends to be balanced. At this time, the opening and closing plate 1209 is driven to reset under the action of the third spring 1208, which can stop the reflux process and continue the spraying process.

[0049] During the spraying operation, the transmission gear 1501 can be driven to rotate synchronously during the operation of the rotating assembly 14, and the stirring blades 1503 can be driven to rotate in the paint barrel 1201, so that the paint is mixed evenly.
