Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying, in particular to electrostatic spraying equipment for a silencer used in an air conditioner. Background Art

[0002] At present, in the production process, the electrostatic spraying of air-conditioning mufflers is generally carried out by contacting the inner wall of the pipe fitting on the muffler with a conductive metal wire and connecting it to the positive electrode, and then spraying negatively charged paint particles. However, the problem caused by this method is that, on the one hand, there is no stable support to realize the mass painting of the muffler, and on the other hand, since the conductive metal wire contacts the inner wall of the pipe fitting, it is easy to cause burns to the inner wall, affecting the product performance of the muffler.

[0003] The Chinese patent with patent number CN107626491A discloses an electrostatic spray bracket and spray method for a silencer for an air conditioner, which optimizes the traditional contact method and adopts a metal contact with a truncated cone-shaped top to contact the bottom edge of the pipe fitting on the silencer. In this way, the metal contact no longer contacts the inner wall of the pipe fitting, avoiding ablation of the inner wall of the pipe fitting during power-on, and reducing the impact on product performance. The silencer is plugged into the horizontal bracket through a rubber sleeve and a metal contact, and the disassembly and assembly speed is fast and efficient. In addition, a plurality of placement holes can be arranged on the horizontal bracket for the electrostatic spray operation of the silencer, which increases the output and is conducive to mass production. The horizontal bracket and the vertical bracket are threadedly connected and fixed by a locking nut. The distance between two adjacent horizontal brackets can be adjusted according to the size of the product, and the operation is convenient.

[0004] A Chinese patent with patent number CN107626491A discloses an electrostatic spray bracket and a spraying method for an air conditioner silencer. Although the purpose of electrostatic spraying of multiple groups of air conditioner silencers can be achieved, when the air conditioner silencers are placed on the spray bracket for spraying, since the bracket is fixed, the spraying of the air conditioner silencers may not be sufficient. To a certain extent, it is not possible to conveniently spray various parts of the air conditioner silencers, which is inconvenient to use.

[0005] Therefore, we have made improvements to this and proposed an electrostatic spraying equipment for silencers of air conditioners. Utility Model Content

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figures 1 to 5 As shown, the utility model is an electrostatic spraying device for a silencer for an air conditioner, comprising a spray box 1, a spray assembly is arranged inside the spray box 1, the spray assembly includes a nozzle 10, a clamping assembly for clamping the air conditioner silencer to be sprayed is arranged inside the spray box 1, the clamping assembly includes a mounting rod 5, a clamping plate 6 is sleeved on the mounting rod 5, a positioning hole 62 is opened on the clamping plate 6, the mounting rod 5 can make a circular rotation inside the spray box 1, and the clamping plate 6 is movably sleeved on the mounting rod 5.

[0023] The air conditioner muffler can be sprayed by using the spray head 10 arranged in the spray box 1. At the same time, the mounting rod 5 rotating in the spray box 1 and the clamping plate 6 sleeved on the mounting rod 5 can more conveniently install multiple air conditioner mufflers at the same time, which is more convenient to use.

[0024] A motor 4 is fixedly connected to the top of the spray box 1, and the output shaft of the motor 4 is vertically downward and fixedly connected to the top of the mounting rod 5 through a coupling. A sleeve portion 61 is opened in the middle of the clamping plate 6, and the inner wall of the sleeve portion 61 is slidably connected to the outer wall of the mounting rod 5.

[0025] By utilizing the motor 4 fixedly connected to the top of the spray box 1 to drive the mounting rod 5 to rotate in a circle, it is easier to drive the air conditioner muffler placed on the clamping plate 6 to rotate, thereby making it easier to spray various parts of the air conditioner muffler.

[0026] The sleeve portion 61 is threadedly connected with a locking bolt, and the end of the locking bolt away from the mounting rod 5 is fixedly connected with a knob 11. The outer wall of the knob 11 is provided with an anti-slip pattern 111. By using the locking bolt threadedly connected at the sleeve portion 61, it is easier to use the locking bolt to fix the position of the clamping plate 6 on the mounting rod 5, which is more convenient to use.

[0027] The spray assembly also includes a mounting groove 7, which is symmetrically provided with two groups. The two groups of mounting grooves 7 are respectively provided on the inner wall of the spray box 1. An electric push rod 8 is fixedly connected to the inner bottom surface of the mounting groove 7. The output shaft of the electric push rod 8 is vertically upward. A slider 9 is fixedly connected to the output end of the electric push rod 8. The nozzle 10 is fixedly connected to the slider 9.
