Description

Technical Field

[0001] This utility model relates to the field of ball valve manufacturing and spraying, and in particular to a ball valve surface coating uniform spraying equipment. Background Technology

[0002] Currently, traditional equipment in the field of ball valve surface coating has significant limitations. On the one hand, the clamping structure has poor adaptability, mostly featuring a fixed-size design. When dealing with ball valves of different specifications, manual disassembly and replacement of clamps are required, a cumbersome and time-consuming adjustment process with low changeover efficiency. Furthermore, manual calibration errors can easily lead to clamp instability, affecting subsequent coating accuracy. On the other hand, the coating mechanism lacks flexibility, with most employing a fixed nozzle design. This makes it difficult to adjust the spraying angle and distance according to the curved shape of the ball valve, easily resulting in blind spots in corners and curved surfaces. The lack of precise spraying frequency control often leads to excessively thick or missed areas, resulting in poor coating uniformity. In addition, some equipment lacks effective protective structures, allowing spray liquid to splash and contaminate the working environment. Overall, it fails to meet the demands of efficient, high-quality coating in mass production.

[0003] While existing technologies can achieve a certain coating effect, they suffer from drawbacks: they lack convenient spacing adjustment and clamping functions, as well as the ability to move and precisely spray multi-directional coverage. In view of this, we propose a ball valve surface coating uniform spraying device that solves the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a ball valve surface coating uniform spraying device.

[0005] The technical solution of this utility model is as follows: A ball valve surface coating uniform spraying device includes a turntable and a mounting base. The upper outer wall of the turntable is provided with a guide rail, and two symmetrical sliders are provided in the guide rail. A second mounting bracket is fixedly connected to the upper outer wall of the slider. A torsion spring is fixedly connected to one side of the outer wall of the second mounting bracket. The outer wall of one side of the second mounting bracket is connected to one side of the outer wall of the mounting base through a bearing. The other side of the outer wall of the mounting base is fixedly connected to one end of the torsion spring. The slider is provided with two symmetrical grooves. One side of the groove is fixedly connected to one end of a helical spring. The other end of the helical spring is fixedly connected to one side of the outer wall of the insertion rod. The outer wall of one side of the guide rail is provided with a plurality of positioning holes arranged in a linear array. The insertion rod is located in the positioning holes. The end of the insertion rod is designed with rounded corners to be embedded in the positioning holes. When the slider moves, the spring can be contracted to overcome the friction, and the insertion rod slides out of the positioning holes.

[0006] When using the ball valve surface coating uniform spraying equipment in this solution, according to the size of the ball valve to be sprayed, two sliders are pushed simultaneously towards each other or back to back to adjust to a suitable distance. The inserts on both sides of the sliders automatically fall into the positioning holes under the action of the helical springs, completing the fixation. The ball valve is placed on the mounting base, and both mounting bases are in contact with the ball valve. At this time, under the action of the ball valve's gravity, the elastic force of the torsion spring is overcome, causing the two mounting bases to rotate at a certain angle. The protrusions on the top of the mounting bases respectively center and clamp the outer walls on both sides of the valve body. Rotating the first baffle connects the first baffle with the two second baffles, which can effectively prevent liquid splashing during spraying. Driving the second rotating motor causes the gear to rotate, changing the position of the moving block, thereby adjusting the spray angle of the nozzle to adapt to the spraying of valve bodies with different shapes. Driving the first rotating motor causes the turntable to rotate, and the valve body fixed on the turntable also rotates together, so that the valve body can be uniformly sprayed from all directions.

[0007] Preferably, the lower outer wall of the turntable is fixedly connected to the upper end of the rotating column, and the rotation center of the rotating column is fixedly connected to the first rotating motor. The first rotating motor is embedded in the machine body, and driving the first rotating motor can make the turntable rotate.

[0008] Preferably, the machine body is fixedly connected to the upper outer wall of the base, and the upper outer wall of the base is provided with two symmetrical second baffles. One of the second baffles is connected to the first baffle through a bearing. The first baffle is designed to be rotatable to facilitate loading and unloading, and at the same time can prevent spraying liquid from splashing.

[0009] Preferably, a controller and a liquid storage tank are fixedly connected to the upper outer wall of the base. Two symmetrical first mounting brackets are fixedly connected to the upper outer wall of the liquid storage tank. A moving block is provided on the first mounting bracket. The controller is connected to the pump body, the first rotating motor, the second rotating motor and the pulse transmitter through a circuit.

[0010] Preferably, a second rotating motor is fixedly connected to one side of the outer wall of the movable block. The output shaft of the second rotating motor is fixedly connected to the rotation center of two gears. The first mounting frame is provided with a rack. The gear meshes with the corresponding rack. Driving the second rotating motor can move the movable block along the first mounting frame.

[0011] Preferably, a pulse transmitter is fixedly connected to the upper outer wall of the movable block, and three nozzles are fixedly connected to one side outer wall of the movable block, with the three nozzles set at different angles.

[0012] Preferably, one side of the outer wall of the movable block is connected to one end of the pipe, and the other end of the pipe is connected to the pump body. The pump body is fixedly connected to one side of the outer wall of the liquid storage tank. One side of the outer wall of the liquid storage tank is provided with a liquid replenishment port, through which the spraying liquid in the liquid storage tank can be replenished. The pump body pumps the spraying liquid to the movable block.

[0013] Compared with existing technologies, the advantages of this utility model are: I. This utility model possesses adaptive centering and clamping capabilities and flexible spacing adjustment functions, exhibiting strong adaptability. Through the movement of the slider along the guide rail, coupled with the insertion rod-coil spring positioning mechanism, the mounting seat spacing can be quickly adjusted according to the ball valve size. Simultaneously, the mounting seat, connected to the bearing via a torsion spring, automatically rotates and centers under the weight of the ball valve, eliminating the need for repeated manual calibration. This allows for stable clamping of ball valves of different specifications, significantly reducing the complexity of valve changeover operations.

[0014] II. Based on the first beneficial effect, the moving block is driven by a second rotating motor to drive a gear, which meshes with the rack of the first mounting bracket to achieve smooth movement. It can flexibly adjust the relative angle between the nozzle and the valve body according to the shape of the ball valve. Furthermore, the moving block has three nozzles with different angles on one side, which can cover the valve body surface from multiple directions. Combined with the precise control of the spraying frequency by the pulse transmitter, it avoids local overspraying or missed spraying. At the same time, combined with the turntable driving the ball valve to rotate, it forms a dual effect of "moving spraying + rotating workpiece", ensuring that the valve body's curved surfaces, corners and other key parts can be evenly covered, completely solving the problem of blind spots in traditional fixed nozzle spraying and significantly improving the overall coating quality.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

When in use, the end of the insert rod 27 is designed with rounded corners and can be inserted into the positioning hole 11. When the slider 25 moves, it can overcome the elastic force of the helical spring 28 and make the insert rod 27 retract and slide out of the positioning hole 11 (here, the slider 25 needs to be adjusted manually as needed). This makes it easy to adjust the distance between the two sliders 25 according to the size of the ball valve to be sprayed. After adjustment, the insert rod 27 automatically engages with the corresponding positioning hole 11 under the action of the helical spring 28, thereby fixing the slider 25.

When loading and unloading materials, the first baffle 15 can be rotated open for easy operation. During the spraying operation, the first baffle 15 is rotated to cooperate with the two second baffles 16 to form a closed protective space, which can effectively block the splashing of spray liquid and keep the working environment clean.

When the pump body 3 is working, it can transport the spraying liquid in the liquid storage tank 5 to the movable block 7 through the pipe 2, and finally spray it out from the nozzle 14, providing a stable supply of paint for the spraying operation.

[0028] Instructions for use: When using this device, according to the size of the ball valve to be sprayed, push the two sliders 25 simultaneously towards each other or back to back to adjust to a suitable distance.
