[0002] The circulating electrostatic powder spraying machine uses the principle of electrostatic spraying to spray the workpiece. The spraying machine is equipped with a powder electrostatic spray gun, a controller and a small powder supply system. The electrostatic powder spraying machine generally has two powder supply forms: powder barrel type and vibrating screen type. The electrostatic powder spraying machine effectively coats the powder on the workpiece through the control of static electricity and aerodynamics, and achieves complete coverage and uniform coating to meet the process requirements.

[0003] For example, the public document with application number 202021214316.8 discloses a circulating powder electrostatic sprayer. The utility model provides a second discharge pipe. When the user is in use, the user can hold the handle and turn the control switch to complete the spraying process, so that the device has the convenience of increasing the length of the spray pipe, which is convenient for the user to use. However, in the circulating powder electrostatic sprayer, the powder barrel is fixed above the base plate, and it is not convenient to disassemble the powder barrel when replacing and cleaning it. The whole equipment can only be connected and moved together for cleaning. For the detachable powder barrel, the powder barrel is directly placed on the base plate, which makes it difficult to ensure the stability of the powder barrel. The powder barrel is easy to tip over during movement, affecting the stability of use.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a circulating powder electrostatic spraying structure is proposed. Utility Model Content

[0005] The utility model aims to provide a circulating powder electrostatic spraying structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circulating powder electrostatic spraying structure, comprising a movable substrate, an air pump is fixedly arranged at the left end above the surface of the movable substrate, a ring groove plate is fixedly arranged in the middle above the surface of the movable substrate, a magnetic attraction plate is fixedly arranged at the bottom of the inner surface of the ring groove plate, an air bag is fixedly arranged around the inner surface of the ring groove plate, the shape of the air bag is annular to match the shape of the ring groove plate, the interior of the air bag is connected to the air pump, and a powder barrel is placed inside the ring groove plate above the surface of the magnetic attraction plate.

[0007] Preferably, a sealing cover is fixedly provided on the surface of the powder barrel by means of a buckle, and a powder pump is fixedly installed on the surface of the sealing cover.

[0008] Preferably, a control console is fixedly arranged on the right end above the surface of the movable substrate, and a placement frame is fixedly arranged on the front side of the control console.

[0009] Preferably, a movable rod is rotatably provided above the front end of the surface of the placement frame via a rotating shaft, and the lower end of the movable rod is locked with the rear side of a raised portion below the front end of the placement frame.

[0010] Preferably, a thrust spring is fixedly provided on the rear side of the surface of the movable rod, and the upper end of the thrust spring is fixedly connected to the inner side of the surface of the placement frame.

[0011] Preferably, a gusset plate is provided inside the placement frame, a circulating electrostatic spray gun is fixedly mounted on the lower end of the gusset plate, and a hollow cavity is formed in the middle of the connection between the circulating electrostatic spray gun and the gusset plate.

[0012] Preferably, the left end of the circulating electrostatic spray gun is fixedly connected with a powder inlet pipe and a power cord in sequence from top to bottom, the powder inlet pipe is connected to the powder pump, and the power cord is connected to the control console.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model arranges an air pump, an annular groove plate, a magnetic plate and an air bag, and the powder barrel is directly placed in the annular groove plate. The annular groove plate limits the placement position of the powder barrel, and the magnetic plate uses magnetic adsorption force to adsorb the bottom end of the powder barrel, so that the powder barrel can be stably and accurately overlapped and placed with the movable base plate, and then the air pump is used to inflate the air bag, so that the air bag expands and clamps the four sides of the powder barrel, so that the powder barrel can be quickly, conveniently and stably assembled and used with the movable base plate, and the powder barrel can also be easily disassembled, replaced and cleaned, making the use of the powder barrel more convenient;

[0015] 2. The utility model arranges a placement frame, a movable rod, a thrust spring and a buckle plate. The buckle plate pushes the movable rod to squeeze the thrust spring and rotate toward the inner and upper side of the placement frame, thereby opening the front end opening of the placement frame. At this time, the buckle plate can be inserted and placed in the placement frame, which is convenient for placing and storing the circulating electrostatic spray gun. After the buckle plate is placed, the thrust spring will push the movable rod to reset, and the protrusion at the lower front end of the placement frame will be used to prevent the movable rod from rotating from the inside to the outside. Therefore, the movable rod is restricted by the protrusion and will firmly block the opening of the placement frame, so that the buckle plate can be stably placed in the placement frame and cannot slip off, which greatly improves the stability of the placement of the circulating electrostatic spray gun and avoids the situation where the circulating electrostatic spray gun slips due to vibration generated during the movement of the equipment.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 2 As shown, a circulating powder electrostatic spraying structure includes a movable substrate 1, an air pump 2 is fixedly arranged on the left end above the surface of the movable substrate 1, a ring groove plate 3 is fixedly arranged in the middle above the surface of the movable substrate 1, a magnetic plate 4 is fixedly installed on the bottom of the inner surface of the ring groove plate 3, an air bag 5 is fixedly installed around the inner surface of the ring groove plate 3, the shape of the air bag 5 is annular and matches the shape of the ring groove plate 3, the inside of the air bag 5 is connected with the air pump 2, the inside of the ring groove plate 3 is located above the surface of the magnetic plate 4 and a powder barrel 6 is placed, a sealing cover 7 is fixedly arranged above the surface of the powder barrel 6 by a buckle, and a powder pump 8 is fixedly installed above the surface of the sealing cover 7.

[0022] Furthermore, the groove in the middle of the annular groove plate 3 is a placement groove for the powder barrel 6, which limits the placement and installation position of the powder barrel 6 above the surface of the movable base plate 1 to prevent the powder barrel 6 from shifting.

[0023] Furthermore, the magnetic plate 4 can utilize magnetic adsorption force to adsorb and fix the powder barrel 6 after placement, thereby preventing the powder barrel 6 from shaking and improving the stability of the placement.

[0024] Furthermore, the airbag 5 can be expanded by the air pump 2 to increase its own volume, squeeze the powder barrel 6 toward the middle, clamp and fix the powder barrel 6, and further improve the stability of the powder barrel 6 to prevent the powder barrel 6 from tipping over.

[0025] Furthermore, the air pump 2 can also be used as an air pump to extract the air in the airbag 5, thereby losing the grip on the powder barrel 6. The powder barrel 6 can be removed by manually applying a little force for maintenance, replacement and cleaning.

[0026] like Figure 1 and Figure 3 As shown, a control console 9 is fixedly arranged on the right end above the surface of the movable substrate 1, a placement frame 10 is fixedly arranged on the front side of the control console 9, a movable rod 11 is rotatably arranged above the front end of the surface of the placement frame 10 through a rotating shaft, the lower end of the movable rod 11 is buckled with the rear side of the raised part below the front end of the placement frame 10, a thrust spring 12 is fixedly arranged on the rear side of the surface of the movable rod 11, the upper end of the thrust spring 12 is fixedly connected to the inner side of the surface of the placement frame 10, a buckle plate 13 is arranged inside the placement frame 10, a circulating electrostatic spray gun 14 is fixedly installed on the lower end of the buckle plate 13, the circulating electrostatic spray gun 14 is connected to the buckle plate 13 in the middle to form a cavity, the left end of the circulating electrostatic spray gun 14 is fixedly connected with a powder inlet pipe 15 and a power cord 16 from top to bottom in sequence, the powder inlet pipe 15 is connected to the powder pump 8, and the power cord 16 is connected to the control console 9.

[0027] Furthermore, a hollow cavity is formed in the middle of the connection between the circulating electrostatic spray gun 14 and the buckle plate 13, so that the buckle plate 13 forms a closed ring, and the circulating electrostatic spray gun 14 can be placed and stored by inserting and overlapping the placement frame 10 ring.

[0028] Furthermore, the length of the movable rod 11 is greater than the placement frame 10, and the bottom end of the movable rod 11 is obliquely arranged at the rear side of the protrusion at the front end of the bottom of the placement frame 10. Therefore, the movable rod 11 can be rotated backward to open the placement frame 10, but cannot be rotated forward to open the placement frame 10. The circulating electrostatic spray gun 14 can be stably placed inside the placement frame 10 through the buckle plate 13 to avoid vibration and shaking off.

[0029] Furthermore, the thrust spring 12 provides the movable rod 11 with a thrust to always rotate forward, so that the movable rod 11 can be closely attached to the rear side of the raised portion at the front end of the bottom of the placement frame 10, preventing the movable rod 11 from opening due to vibration.

[0030] Furthermore, the lengths of the powder inlet pipe 15 and the power cord 16 can meet the extension and dragging requirements of the circulating electrostatic spray gun 14 .

[0031] Working principle: When using the circulating powder electrostatic spraying structure, first, fill the powder barrel 6 with the required powder, then cover the sealing cover 7, lift the powder barrel 6 and put it into the ring groove plate 3, the magnetic suction plate 4 will use the magnetic adsorption force to adsorb the bottom end of the powder barrel 6, and then start the air pump 2 to inflate the airbag 5, so that the airbag 5 expands to clamp the four sides of the powder barrel 6, fix the powder barrel 6, and then turn on the power of the console 9 to start the equipment, use the circulating electrostatic spray gun 14 to aim at the workpiece for spraying, and after the spraying is completed, push the movable rod 11 through the buckle plate 13 to squeeze the thrust spring 12 to the placement frame 10 The inner upper part is rotated to open the front end opening of the placement frame 10. At this time, the buckle plate 13 can be inserted and placed in the placement frame 10, which is convenient for placing and storing the circulating electrostatic spray gun 14. After the buckle plate 13 is placed, the thrust spring 12 will push the movable rod 11 to reset, and the protrusion at the lower front end of the placement frame 10 is used to prevent the movable rod 11 from rotating from the inside to the outside. Therefore, the movable rod 11 is restricted by the protrusion and will firmly block the opening of the placement frame 10, so that the buckle plate 13 is stably placed in the placement frame 10 and cannot slip off. This is the working principle of the circulating powder electrostatic spraying structure.
