Description

Technical Field

[0001] The utility model belongs to the technical field of surface treatment, and particularly relates to an automatic powder spraying device. Background Art

[0002] A nut is a common component used to form a fastening function with corresponding components, so it is widely used in various equipment production activities.

[0003] Common nut materials include stainless steel, carbon steel, metal, etc. In order to cope with the complex environment and prevent nuts from rusting, it is necessary to perform surface treatment of powder spraying on the nut surface, so as to cope with various harsh environments that affect the nut life.

[0004] Common nut powder spraying devices are divided into centralized powder spraying and single-nut powder spraying. Due to factors such as nut stacking, position placement, and fixed powder spraying points caused by a single spray nozzle in the centralized powder spraying method, it is easy to cause inconsistent powder spraying effects on each nut, resulting in the problem that the surface treatment quality cannot be guaranteed. For a device that sprays powder on a single nut only once, the powder spraying quality can be guaranteed, but the powder spraying efficiency is low, affecting the time cost.

[0005] At the same time, most of the existing powder spraying devices use cylinders for the displacement movement of the powder spraying pipe. The reciprocating action of the cylinder causes the powder spraying pipe to be unable to be precisely adjusted, resulting in fixed powder spraying points. Before the powder spraying operation starts, calibration is required to avoid the problem that the powder spraying point is too close or too far from the nut.

[0006] Furthermore, during the existing powder spraying process, the powder is easily splashed and spread in the air when sprayed on the nut, which not only affects the health of the operator but also causes unnecessary trouble for the subsequent powder recovery and cleaning, increasing the production cost. Therefore, a solution is needed to solve the above problems.

[0007] It should be noted that the above content belongs to the technical cognition scope of the utility model person and does not necessarily constitute the prior art. Summary of the Utility Model

[0008] In order to solve the above problems, the purpose of the utility model is to provide an automatic powder spraying device that can further precisely adjust the spraying position of the powder spraying pipe during the powder spraying process through a servo motor, so as to achieve uniform powder spraying.

[0009] To achieve the above object, the present utility model provides an automatic powder spraying device, which includes a vertical standing plate. On one side of the standing plate, a groove is opened along the vertical direction of the standing plate. A guide rail is fixedly embedded in the groove. A first slider is movably embedded on the guide rail. On the side of the first slider away from the guide rail, an upper powder spraying rack is fixedly provided. Along the length direction of the upper powder spraying rack, a plurality of vertically arranged powder spraying pipes are spacedly penetrated. The powder spraying pipes penetrate through the upper powder spraying rack and extend to the lower part of the upper powder spraying rack. A spiral nozzle is embedded in the powder spraying pipe. A servo motor is also mounted on the top of the upper powder spraying rack. The servo motor is connected to the powder spraying pipe through a linkage plate. The top of the first slider is connected to a first cylinder. A nut fixing table is arranged directly below the upper powder spraying rack.

[0010] In one example, a second slider is also movably embedded on the guide rail. On the side of the second slider away from the guide rail, a lower powder spraying rack is fixedly provided. Along the length direction of the lower powder spraying rack, a plurality of vertically arranged powder suction pipes are spacedly penetrated. One end of the powder suction pipe penetrates through the lower powder spraying rack and is aligned with the nut fixing table, and the other end is connected to a negative pressure device. The bottom of the second slider is connected to a second cylinder.

[0011] In one example, the upper and lower ends of the standing plate are respectively connected to an upper extension plate and a lower extension plate. The first cylinder is fixedly arranged on the upper extension plate, and the second cylinder is fixedly arranged on the lower extension plate.

[0012] In one example, a support column is fixedly connected to one side of the standing plate. The support column is located on the side of the standing plate away from the guide rail.

[0013] In one example, the number of the powder spraying pipes is adapted to the number of the powder suction pipes.

[0014] In one example, a fixing sleeve is sleeved outside the powder spraying pipe. The fixing sleeve is located at the lower part of the powder spraying pipe.

[0015] In one example, through holes adapted to the number of the powder spraying pipes are opened on the linkage plate.

[0016] In one example, a working hole for fixing a nut is opened on the nut fixing table.

[0017] In one example, a first stabilizing block is arranged on the upper powder spraying rack. The first stabilizing block is located at the connection between the fixing sleeve and the upper powder spraying rack. A second stabilizing block is arranged on the lower powder spraying rack. The second stabilizing block is located at the connection between the powder suction pipe and the lower powder spraying rack.

[0018] In one example, one end of the powder spraying pipe away from the spiral nozzle is connected to a powder material pressure tank. An electric proportional valve is arranged on the powder material pressure tank.

[0019] An automatic powder spraying device proposed by the present utility model can bring the following beneficial effects:

[0020] 1. By arranging a spiral nozzle at the powder spraying end of the powder spraying pipe, the powder material is ejected in a spiral manner, ensuring that the powder material can be concentrated at the spraying point, thereby achieving the effect of controlling the powder spraying range, solving the problem that the powder material directly impacts the nut and causes splashing in traditional direct spraying, and improving the powder spraying efficiency and quality;

[0037] As Figures 1 to 6 shown, an embodiment of the present utility model provides an automatic powder spraying device, which is characterized in that it includes a vertical standing plate 1. On one side of the standing plate 1, a groove 11 is opened along the vertical direction of the standing plate 1. A guide rail 2 is fixedly embedded in the groove 11. A first slider 21 is movably embedded on the guide rail 2. On the side of the first slider 21 away from the guide rail 2, an upper powder spraying frame 3 is fixedly provided. Along the length direction of the upper powder spraying frame 3, a plurality of vertically arranged powder spraying pipes 31 are spacedly penetrated. The powder spraying pipes 31 penetrate through the upper powder spraying frame 3 and extend below the upper powder spraying frame 3. A spiral nozzle 32 is embedded in the powder spraying pipes 31. A servo motor 5 is also mounted on the top of the upper powder spraying frame 3. The servo motor 5 is connected to the powder spraying pipes 31 through a linkage plate 6, so that the powder spraying pipes 31 are vertically displaced along the extension direction of the servo motor 5. The top of the first slider 21 is connected to a first cylinder 7, so that the first slider 21 is vertically displaced along the extension direction of the first cylinder 7. The movement of the first cylinder 7 drives the upper powder spraying frame 3 to approach the direction of the nut fixing table 9. The servo motor 5 controls the movement of the powder spraying pipes 31 to a specified position for powder spraying operation. During the powder spraying process, the servo motor 5 can freely control the extension and contraction of the output end to make the powder spraying pipes 31 move up and down, so as to realize that the powder spraying pipes 31 can freely move up and down to adjust the powder spraying points, achieving the purpose of uniform powder spraying. The spiral nozzles enable the powder to be sprayed in a spiral manner, ensuring that the powder can be concentrated at the spraying point, thereby achieving the effect of controlling the powder spraying range. The spiral powder spraying can solve the problem that the sprayed material directly impacts the nut and causes splashing in direct powder spraying, further improving the powder spraying efficiency and the powder spraying quality.

[0038] Specifically, a second slider 22 is also movably embedded on the guide rail 2. On the side of the second slider 22 away from the guide rail 2, a lower powder spraying frame 4 is fixedly provided. Along the length direction of the lower powder spraying frame 4, a plurality of vertically arranged powder suction pipes 41 are spacedly penetrated. One end of the powder suction pipes 41 penetrates through the lower powder spraying frame 4 and is aligned with the nut fixing table 9, and the other end is connected to a negative pressure device 10. The bottom of the second slider 22 is connected to a second cylinder 8, so that the second slider 22 is vertically displaced along the extension direction of the second cylinder 8.

[0039] Driven by the second slider 22, the lower powder spraying rack 4 moves closer to the direction of the nut fixing table 9. The lower powder spraying rack 4 and the upper powder spraying rack 3 cooperate to clamp and fix the nut fixing table 9, preventing the nut fixing table 9 from shaking during the powder spraying process and affecting the powder spraying accuracy.

[0040] Specifically, the upper and lower ends of the vertical plate 1 are respectively connected to the upper extension plate 12 and the lower extension plate 13. The first cylinder 7 is fixedly arranged on the upper extension plate 12, and the second cylinder 8 is fixedly arranged on the lower extension plate 13.

[0041] Specifically, one side of the vertical plate 1 is fixedly connected to the support column 14, and the support column 14 is located on the side of the vertical plate 1 away from the guide rail 2.

[0042] Specifically, the number of powder spraying pipes 31 is adapted to the number of powder suction pipes 41.

[0043] Specifically, a fixing sleeve 33 is sleeved outside the powder spraying pipe 31. The fixing sleeve 33 is located at the lower part of the powder spraying pipe 31, which is used to prevent the powder spraying pipe 31 from deforming and shaking due to air pressure during the powder spraying process, thus affecting the accuracy of powder spraying.

[0044] Specifically, through holes 61 adapted to the number of powder spraying pipes 31 are formed in the linkage plate 6. The linkage plate clamps and fixes the powder spraying pipes 31. Thus, during the process of the servo motor 5 pushing the linkage plate 6 to move, the powder spraying pipes 31 can be pulled to move together, realizing the adjustment of the powder spraying points during the powder spraying process, so as to achieve uniform powder spraying on the nut workpieces.

[0045] Specifically, a working hole 91 for fixing nuts is formed in the nut fixing table 9. Through the working hole 91, not only can the nut workpieces be fixed, but also the powder suction pipe 41 can work through the negative pressure device 10 on the lower end surface of the nut to suck away the excess sprayed material, preventing the powder from accumulating on the nut and improving the quality of nut powder spraying.

[0046] Specifically, a first stabilizing block 34 is arranged on the upper powder spraying rack 3, and the first stabilizing block 34 is located at the connection between the fixing sleeve 33 and the upper powder spraying rack 3. A second stabilizing block 42 is arranged on the lower powder spraying rack 4, and the second stabilizing block 42 is located at the connection between the powder suction pipe 41 and the lower powder spraying rack 4, which is used to further strengthen the connection between the pipe body and the fixing rack, preventing the powder spraying pipe 31 and the powder suction pipe 41 from shaking due to air pressure during the powder spraying and powder suction operations, thus affecting the powder spraying quality.

[0047] Specifically, one end of the powder spraying pipe 31 far from the spiral nozzle 32 is connected to the powder material pressure tank 35. An electro-hydraulic proportional valve 351 is arranged on the powder material pressure tank 35. Each powder spraying pipe 31 is respectively connected to the corresponding powder material pressure tank 35 to ensure the normal operation of each powder spraying pipe 31. The powder output of the powder material pressure tank is controlled by the electro-hydraulic proportional valve, so as to control the powder spraying amount of the powder spraying pipe.

[0048] Working principle: First, the first cylinder drives the first slider to vertically displace on the guide rail, and the second cylinder drives the second slider to vertically displace on the guide rail, so that the upper powder spraying rack and the lower powder spraying rack approach and abut against the nut processing table together, thereby completing the clamping of the nut fixing table, avoiding the shaking of the nut fixing table caused by the airflow generated during the powder spraying process. Subsequently, the electro-pneumatic proportional valve controlling the powder pressure tank and the negative pressure device is opened for powder spraying operation. During the powder spraying process, the sprayed material is ejected through the spiral nozzle, forming a spiral jet flow towards the nut, enabling the powder to be concentrated at the spraying point, thereby achieving the effect of controlling the powder spraying range. Spiral powder spraying can solve the problem of splashing caused by the direct impact of the sprayed material on the nut during direct powder spraying. The excess powder is sucked out by the suction pipe using the negative pressure device, thereby improving the powder spraying quality and efficiency. Moreover, during the powder spraying process, the servo motor is used to freely adjust the extension and contraction of the output end, and cooperate with the linkage plate fixedly connected to the powder spraying pipe to further precisely control the up and down movement of the powder spraying pipe, thereby achieving the effect of adjusting the powder spraying position of the powder spraying pipe during the powder spraying process, ensuring that the powder can be sprayed more evenly on the nut. A plurality of powder spraying pipes can be arranged on the upper powder spraying rack, corresponding to the corresponding number of working holes on the nut fixing table, thereby realizing the powder spraying operation on a plurality of nuts at one time, improving the production efficiency and reducing the production time.
