Description

Technical Field

[0001] This utility model relates to the technical field of paint supply devices, and in particular to an automotive electrostatic paint supply device. Background Technology

[0002] Electrostatic spraying is an advanced technology that uses the principle of electrostatic adsorption for painting. During the electrostatic spraying process, the paint is atomized into tiny particles by the spray gun, and at the same time, the spray gun and the car body being sprayed are charged with opposite charges. According to the principle that opposite charges attract each other, the atomized paint particles fly at high speed towards the car body along the direction of the electric field and are evenly adsorbed on the surface of the car body, forming a high-quality paint film.

[0003] Currently, in existing paint supply devices, such as the patent with announcement number CN222267638U, this utility model provides a paint supply structure for a double-roller coating machine for panel painting, which relates to the field of panel painting technology. It includes: a base, a roller coating cover installed on the top of the base, a paint box set on the top of the roller coating cover, a locking component, which is set between the roller coating cover and the paint box for disassembling the paint box, and a feeding component, which is set inside the paint box for controlling the amount of paint fed into the paint box.

[0004] It has been found in practice that existing technologies are not convenient for crushing the powder used in electrostatic spraying, which can easily lead to large pieces of powder clogging the spray gun, thereby reducing the reliability of spraying and affecting work efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive electrostatic paint supply device that effectively reduces the blockage caused by large pieces of powder paint entering the spray gun and lowers maintenance costs.

[0006] This utility model discloses an electrostatic paint supply device for automobiles, comprising a first tank and a feed inlet connected to the top of the first tank; it also includes a storage device, a grinding ring, a grinding disc, and a motor. The grinding ring is mounted on the inner wall of the first tank, and the top of the grinding disc is rotatably mounted on the inner wall of the first tank. A gap is provided between the grinding disc and the grinding ring, with the gap decreasing from top to bottom. The motor is mounted on the top of the first tank, and its output end is connected to the grinding disc. The bottom of the first tank is connected to the storage device, which is used to store and transport the powder paint. Discharge: Powder coating is fed into the first tank through the inlet. The powder coating falls into the gap between the grinding ring and the grinding disc. The grinding disc is rotated by the motor, and the grinding disc and the grinding ring grind the powder coating. The ground powder coating falls into the storage device for storage. When needed, the powder coating is discharged out into the spray gun through the storage device, which effectively reduces the possibility of large pieces of powder coating entering the spray gun and causing blockage, and reduces maintenance costs. By gradually reducing the gap between the grinding ring and the grinding disc from top to bottom, it helps the powder coating to flow freely into the gap.

[0007] Preferably, the storage device includes a second tank, a discharge pipe, a blower, a sealing door, a cylinder, and a guide rail. The top of the second tank has a feed inlet, and the bottom of the first tank communicates with the feed inlet of the second tank. The discharge pipe is connected to the bottom of the second tank. The blower is installed on the outer wall of the second tank, and its output end is connected to the second tank. Two sets of sealing doors are slidably installed at the feed inlet of the second tank via the guide rail. Two sets of cylinders are installed on the inner wall of the second tank, and their output ends are respectively connected to the two sets of sealing doors. The ground powder coating in the first tank falls into the second tank for storage. When the powder coating in the second tank needs to be discharged, the two sets of cylinders push the two sets of sealing doors to close, sealing the feed inlet of the second tank. Then, the blower is activated to blow air into the second tank, thereby allowing the powder coating in the second tank to be discharged through the discharge pipe via pneumatic conveying, improving the convenience of discharging and using the powder coating.

[0008] Preferably, it also includes a rotating shaft, a support, stirring blades, and spiral blades. The top end of the rotating shaft is fixedly connected to the bottom end of the grinding disc, and the bottom end of the rotating shaft is rotatably connected to the support. The support is installed on the inner side wall of the second tank, and the stirring blades and spiral blades are respectively installed on the outer side wall of the rotating shaft. When the grinding disc rotates, it drives the rotating shaft to rotate. After the rotating shaft rotates, it drives the stirring blades to move circumferentially, thereby stirring the powder coating stored in the second tank, avoiding the deposition and clumping of the powder coating, and improving the convenience of powder coating discharge. After the rotating shaft rotates, it drives the spiral blades to rotate, so that the spiral blades assist in transporting the powder coating in the first tank to the second tank.

[0009] Preferably, it also includes a heat-conducting inner liner and an electric heating element. The heat-conducting inner liner is disposed on the inner side wall of the first tank, and the electric heating element is disposed on the inner side wall of the heat-conducting inner liner. The heat-conducting inner liner is heated by the electric heating element, so that the heat-conducting inner liner heats and dries the powder coating in the first tank through heat conduction, thereby improving the convenience of dehumidification of the powder coating.

[0010] Preferably, it also includes a first scraper, which is installed on the outer wall of the rotating shaft; after the rotating shaft rotates, it drives the first scraper to move circumferentially, so that the first scraper scrapes off the powder coating adhering to the heat-conducting inner liner.

[0011] Preferably, it also includes a second scraper, which is installed on the outer wall of the grinding disc; after the grinding disc rotates, it drives the second scraper to move circumferentially, so that the second scraper scrapes off the powder coating deposited on the top of the grinding ring.

[0012] Preferably, an arc-shaped notch is provided between the two sets of closed doors, and the combined shape of the arc-shaped notch matches the diameter of the rotating shaft; when the two sets of closed doors are closed, the arc-shaped notch seals the two sets of closed doors with the rotating shaft, thereby improving the sealing effect on the feed inlet of the second tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the powder coating is put into the first tank through the feed port. The powder coating entering the first tank falls into the gap between the grinding ring and the grinding disc. The grinding disc is rotated by the motor, so that the grinding disc and the grinding ring cooperate to grind the powder coating. The ground powder coating falls into the storage device for storage. When it is needed, the powder coating is discharged out into the spray gun through the storage device, thereby effectively reducing the situation where large pieces of powder coating enter the spray gun and cause blockage, reducing maintenance costs. By gradually reducing the gap between the grinding ring and the grinding disc from top to bottom, it helps the powder coating to flow into the gap. Attached Figure Description
