Description

Technical Field

[0001] The present application relates to the technical field of spraying equipment, and in particular to an inverter filter spraying device. Background Art

[0002] The filter is a commonly used functional component on the inverter. Common filters include woven, mechanically pressed and punched types. Some of these filters are made of alloy materials and have good corrosion resistance. However, some filters use materials with poor corrosion resistance due to cost considerations or require the filter to have a longer service life, so a layer of waterproof and rust-proof paint needs to be sprayed on its surface.

[0003] Most existing spraying methods are manual spraying, which can better ensure uniform spraying. There are also automated spraying devices, but for filters with a certain mesh thickness, it is difficult for the paint in the mesh to reach a suitable adhesion thickness after spraying. The inner wall of the filter mesh is more easily exposed to the air and continuously damaged due to the lack of protective coating. Summary of the invention

[0008] As a preferred embodiment, the ends of the two booster hoppers that are away from each other are fixedly connected to a driven shaft coaxial with the transmission shaft, and the driven shaft and the separation sleeve constitute a rotating pair. The lower ends of the two booster hoppers are commonly connected to a spray rod, which is suitable for evenly spraying paint onto the filter screen. Combined with a uniform movement speed, the paint can be evenly covered on the surface of the filter screen.

[0009] As a preferred embodiment, a sliding plate is fixedly connected to the upper surface of the cross plate near both ends, and the sliding plate has a sliding groove suitable for forming a sliding pair with the guide rail. The sliding plate has a motor and a reducer for driving the sliding plate to slide along the guide rail to achieve automatic motion control.

The spraying mechanism 5 includes a configuration frame 510 and a swing assembly 520, and the swing assembly 520 can rotate relative to the configuration frame 510 to change the spraying inclination angle, and the configuration frame 510 includes a horizontal plate 511, and the lower surface of the horizontal plate 511 has a separation sleeve 512 and a conjoined sleeve 513, and the separation sleeve 512 has two ends respectively close to the horizontal plate 511, and the conjoined sleeve 513 is located in the middle of the horizontal plate 511. In this way, the two separate sleeves 512 are equally spaced from the integrated sleeve 513. Both the separate sleeves 512 and the integrated sleeve 513 are suitable for constraining the freedom of the swing assembly 520. The swing assembly 520 includes a pair of symmetrical booster hoppers 522, which can increase the pressure of the sprayed material. A transmission shaft 524 is fixedly connected between the booster hoppers 522 and is suitable for passing through the integrated sleeve 513 to form a rotating pair. A swing groove 514 that passes through the integrated sleeve 513 is provided on the upper surface of the cross plate 511. A swing arm 525 is fixedly connected to the upper surface of the transmission shaft 524 and is suitable for driving the transmission shaft 524 to rotate. The swing arm 525 can swing in a fan shape in the swing groove 514.

[0030] The upper surface of the horizontal plate 511 is fixedly connected with a sliding plate 550 near both ends. The sliding plate 550 has a slide groove 551, which is suitable for forming a sliding pair with the guide rail 1 to constrain the freedom of movement of the sliding plate 550. The sliding plate 550 has a motor and a reducer for providing power to drive the sliding plate 550 to slide along the guide rail 1. A bow plate 540 is fixedly connected between the two sliding plates 550. A telescopic device 530 is arranged between the bow plate 540 and the swing arm 525. In this embodiment, a low-cost cylinder or an electric telescopic rod with higher control accuracy is used. The telescopic device The two ends of 530 are movably connected to the bow plate 540 and the swing arm 525 through hinges respectively. The ends of the two booster hoppers 522 that are away from each other are fixedly connected to a driven shaft 523 coaxial with the transmission shaft 524. The driven shaft 523 and the separation sleeve 512 form a rotating pair to ensure that the telescopic device 530 has sufficient angular freedom when performing telescopic movement to adapt to changes in its own inclination angle. The lower ends of the two booster hoppers 522 are commonly connected to a spray rod 521. The lower end surface of the spray rod 521 is provided with a plurality of evenly arranged nozzles, which are suitable for evenly spraying paint onto the filter.

[0031] A pair of symmetrical rotating mechanisms 3 are arranged between the columns 4. The spraying mechanism 5 is located between the two rotating mechanisms 3 in the horizontal direction, that is, the spraying mechanism 5 can only move between the rotating mechanisms 3. The filter is installed between the two rotating mechanisms 3 and can rotate. The rotating mechanism 3 includes a mounting frame 303 fixedly connected to the column 4. The mounting frame 303 is fixedly connected to a driving mechanism 302. The output ends of the two driving mechanisms 302 are opposite and fixedly connected with a clamping plate 301. The driving mechanism 302 includes a motor and a reducer. It is used to provide a larger rotational torque to the clamping plate 301, and the clamping plate 301 is suitable for clamping the frame of the filter screen, so as to ensure the stability of the filter screen while driving the filter screen to rotate.

[0032] Working principle: When working, the filter screen to be painted is inserted between the two horizontal clamping plates 301. The spray rod 521 in the initial state has a certain inclination angle relative to the vertical direction, and the spraying is opened. The spraying mechanism 5 moves from one end of the guide rail 1 to the other end. Since the spraying direction of the spray is inclined, the inner wall of the filter mesh is more easily attached with the spray material. Then, driven by the telescopic device 530, the spray rod 521 is turned to another inclined direction, and then returned to the initial position from the other end. Then, the inner wall of the other side of the filter mesh will also be attached with the spray material. At this time, the upper surface of the filter screen is sprayed. The filter screen is turned 180° driven by the rotating mechanism 3, and the other side can be sprayed according to the above steps. After the spraying is completed, the filter screen is removed and the next round of spraying can be carried out.
