Description

Technical Field

[0001] This utility model relates to the field of electrostatic spraying technology, specifically to an anti-interference magnetic ring electrostatic spraying device. Background Technology

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic field to cause negatively charged paint particles to move in the opposite direction of the electric field and to adsorb the paint particles onto the surface of the workpiece. The workpiece enters the spray gun position in the powder spraying booth through a conveyor chain to prepare for the spraying operation. The electrostatic generator releases high-voltage static electricity (negative pole) into the space in the direction of the workpiece through the electrode needle of the spray gun nozzle. This high-voltage static electricity ionizes the mixture of powder and compressed air sprayed from the spray gun nozzle and the air around the electrode (carries a negative charge).

[0003] Among the existing technologies, the authorized announcement number CN219560089U proposes an anti-interference magnetic ring electrostatic spraying device, which includes an electrostatic spraying device body, a clamping plate and a spraying placement box. The front of the electrostatic spraying device body is provided with an anti-interference sealed sliding door. Several first electric telescopic rods are fixedly installed at the bottom of the inner wall of the spraying placement box, and a movable plate is fixedly installed at the drive end of the first electric telescopic rod.

[0004] Existing technologies cannot quickly fix anti-interference magnetic rings with different inner and outer diameters. During spraying, some areas of the anti-interference magnetic ring cannot be covered, and the spraying position is not uniform. To address this, we propose an electrostatic spraying device for anti-interference magnetic rings. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an anti-interference magnetic ring electrostatic spraying device that can perform electrostatic spraying on anti-interference magnetic rings with different inner and outer diameters, while ensuring more uniform and comprehensive coverage of the anti-interference magnetic rings, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference magnetic ring electrostatic spraying device, comprising a mounting platform, a limiting component, a drive wheel component, and a spraying component;

[0007] Mounting platform: The upper part is equipped with limit components, drive wheel components and spraying components;

[0008] Limiting assembly: includes mounting plate one, motor one, gear, fixed shaft, hollow cylinder, gear ring and rotating disk. Mounting plate one is fixedly connected to the middle of the upper rear side of the mounting platform. Fixed shaft is fixedly connected to the upper end of mounting plate one. Motor one is fixedly connected to the middle of the front end of mounting plate one. Gear is fixedly connected to the output shaft of motor one. Hollow cylinder is rotatably connected to the outside of fixed shaft. Gear ring is fixedly connected to the outside of hollow cylinder. Gear meshes with gear ring. Rotating disk is fixedly connected to the front end of hollow cylinder.

[0009] The device integrates a limiting component, a drive wheel component, and a spraying component on a mounting platform. The limiting component uses a motor to drive a gear ring to rotate, so that the hollow cylinder and the rotating disk rotate synchronously, achieving circumferential positioning of the magnetic ring. It features a modular design and high space utilization. Meanwhile, the fixed shaft is grounded through a wire.

[0010] Furthermore, the limiting component also includes a connecting rod, a sliding frame, a sliding block, and a rotating wheel. Four sliding frames are fixedly connected to the outer front end of the fixed shaft. A sliding block is slidably connected to the inner side of the sliding frame. A rotating wheel is rotatably connected to the front end of the sliding block. One end of the connecting rod is hinged to the rear end of the sliding block, and the other end of the connecting rod is hinged to the outer eccentric position of the rotating disk.

[0011] The limiting assembly, via a rotating disk and an eccentrically hinged connecting rod, pushes four sliding blocks radially within the sliding frame, causing the rotating wheel to clamp or release the magnetic ring, forming a four-point synchronous positioning structure. This structure offers advantages such as self-adaptive clamping and precise center positioning.

[0012] Furthermore, the drive wheel assembly includes a collection trough, a self-locking electric telescopic rod, a mounting frame, a drive wheel, and a second motor. The collection trough is located at the upper center of the mounting platform. The self-locking electric telescopic rod is fixedly connected to the upper center of the mounting platform. The mounting frame is fixedly connected to the upper end of the self-locking electric telescopic rod. The drive wheel is rotatably connected to the upper rear side of the mounting frame. The second motor is fixedly connected to the upper front side of the mounting frame. The output shaft of the second motor is fixedly connected to the self-locking electric telescopic rod. The drive wheel assembly drives the drive wheel to rotate via the second motor, which in turn drives the magnetic ring to rotate. The self-locking electric telescopic rod adjusts the height of the mounting frame to accommodate magnetic rings of different sizes. The collection trough collects dripping paint, integrating magnetic ring rotation drive and height adjustment for convenient subsequent spraying.

[0013] Furthermore, the spraying assembly includes a second mounting plate, a second self-locking electric telescopic rod, a first nozzle mounting bracket, a second nozzle mounting bracket, and a nozzle. Two second mounting plates are fixedly connected to the upper left and right sides of the mounting platform. A second self-locking electric telescopic rod is fixedly connected to the upper front side of the second mounting plate. The horizontal angle between the second self-locking electric telescopic rod and the center of the fixed axis is 45 degrees. The movable end of the left self-locking electric telescopic rod is fixedly connected to the first nozzle mounting bracket, and the movable end of the right self-locking electric telescopic rod is fixedly connected to the second nozzle mounting bracket. Multiple nozzles are fixedly connected to the inner side of the second nozzle mounting bracket and the first nozzle mounting bracket.

[0014] The spraying assembly uses two self-locking electric telescopic rods arranged symmetrically at 45 degrees to control the extension and retraction of the nozzle mounting brackets 1 and 2 respectively. Multiple nozzles enable simultaneous spraying on both sides, providing the advantages of uniform spraying and comprehensive coverage.

[0015] Furthermore, the spraying assembly also includes a filter box, a first connecting pipe, a second connecting pipe, a storage tank, a water pump, and a delivery pipe. The filter box is fixedly connected to the lower front side of the mounting platform. The inner side of the collection tank is connected to the filter box via the first connecting pipe. The second connecting pipe is fixedly connected to the lower rear side of the mounting platform. The outlet of the filter box is connected to the storage tank via the second connecting pipe. Two water pumps are fixedly connected to the rear end of the storage tank. The inlets of the water pumps are connected to the storage tank. One end of the delivery pipe is fixedly connected to the outlet of the water pump. One end of the right delivery pipe passes through the mounting platform and connects to the second nozzle mounting bracket, and one end of the left delivery pipe passes through the mounting platform and connects to the nozzle. The spraying assembly incorporates a circulation system. Waste liquid from the collection tank is guided into the filter box for purification via the first connecting pipe and then returned to the storage tank via the second connecting pipe. The water pump supplies material to the nozzle through the delivery pipe, forming a closed-loop utilization of the coating, which is environmentally friendly, energy-saving, and has low operating costs.

[0016] Furthermore, it also includes support legs and an anti-interference magnetic ring. Four support legs are fixedly connected to the four corners of the lower end of the mounting platform. The inner side of the anti-interference magnetic ring contacts the drive wheel, and the outer side of the anti-interference magnetic ring contacts the drive wheel. The support legs provide stable support, and the anti-interference magnetic ring and the drive wheel form a transmission, driving the anti-interference magnetic ring to rotate and spray.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-interference magnetic ring electrostatic spraying device has the following advantages:

[0018] 1.
