Description

Technical Field

[0001] This invention belongs to the field of powder coating technology, and more specifically, relates to an ultrasonic vibration-assisted fine grinding device for powder coating. Background Technology

[0002] Powder coating requires fine grinding to ensure coating quality; insufficient grinding will lead to uneven dispersion of pigment particles, resulting in problems such as uneven paint film, low gloss and poor weather resistance; uniform fineness can improve pigment hiding power and adhesion, avoid pinhole defects, and enhance the density of the coating film; therefore, the grinding process directly determines the application performance of the powder and the durability of the final coating.

[0003] The powder grinding equipment currently in use still has the following problems: 1. It generally lacks ultrasonic vibration assistance, which reduces the grinding effect of the sprayed powder; 2. It cannot automatically change the position of the sprayed powder during the grinding process, which also affects the grinding effect of the sprayed powder; 3. It cannot automatically detect whether unauthorized personnel are approaching the grinding equipment, causing the grinding equipment to always be in working condition, which poses a safety hazard.

Furthermore, because the arc-shaped connecting block 404 is slidably mounted on the two arc-shaped guide rods 403, and four helical springs b405 are sleeved on the outside of the two arc-shaped guide rods 403, the arc-shaped connecting block 404 can move along the two arc-shaped guide rods 403. Also, because the two control switches 406 are fixedly mounted on the arc-shaped connecting block 404, when the tilt detection frame 402 is not in contact with unauthorized personnel, the two control switches 406 are always in an unpressed state. At this time, the servo motor a205 and the two ultrasonic vibrators 202 continue to work. When the tilt detection frame 402 comes into contact with unauthorized personnel, after the arc-shaped connecting block 404 slides a certain distance, one of the control switches 406 is pressed.

[0027] The specific usage and function of this embodiment are as follows: In use, the rectangular support plate 101 is first fixedly installed with bolts. Then, the control panel 500 is connected to an external power source. The coating powder to be ground is poured into the powder grinding shell 201. The control panel 500 then starts the servo motor a205, two ultrasonic vibrators 202, and servo motor b408. When the control panel 500 controls the servo motor a205 to work, the output shaft of the servo motor a205 drives the powder grinding blade 206 to rotate, achieving fine grinding of the coating powder. When the control panel 500 controls the two ultrasonic vibrators 202 to work, the two ultrasonic vibrators 202 vibrate the coating powder in the powder grinding shell 201. This design is beneficial for improving the grinding effect of sprayed powder. When the servo motor a205 and the two ultrasonic vibrators 202 are working, the powder grinding shell 201 can move up and down reciprocally under the elastic force of the four helical springs a105, the grinding force, and the vibration force. When the control panel 500 controls the servo motor b408 to work, the arc-shaped connecting block 404 drives the arc-shaped mounting frame 401 to move back and forth automatically. When the tilt detection frame 402 is not in contact with unauthorized personnel, the two control switches 406 are always in the unpressed state. At this time, the servo motor a205 and the two ultrasonic vibrators 202 continue to work. When the tilt detection frame 402 comes into contact with unauthorized personnel, the arc-shaped connecting block 404 slides a certain distance. After a certain distance, one of the control switches 406 is in the pressed state. At this time, the servo motor a205 and the two ultrasonic vibrators 202 stop working, reducing safety hazards. When the powder grinding shell 201 moves downward, the two movable control frames 302 rotate outward simultaneously. When the powder grinding shell 201 moves upward, the two movable control frames 302 rotate inward simultaneously. When the two movable control frames 302 rotate outward simultaneously, the two arc-shaped connecting plates 305 drive the two arc-shaped auxiliary sleeves 304 to move inward, which squeezes the powder in the powder grinding shell 201 and can automatically change the position of the powder, which is beneficial to improving the grinding effect of the powder. When the two movable control frames... When 302 rotates inwards simultaneously, the two arc-shaped connecting plates 305 drive the two arc-shaped auxiliary sleeves 304 to move outwards, causing the sprayed powder in the powder grinding shell 201 to change position and thus alter its location. When the sprayed powder after fine grinding needs to be discharged, the operator moves the external powder collection device to the bottom of the powder grinding shell 201, and then unscrews the sealing bottom cover 203 with a wrench. During the discharge of the sprayed powder after fine grinding, the servo motor a205 can be controlled by the control panel 500 to drive the powder grinding blade 206 to rotate slowly, which facilitates the rapid discharge of the sprayed powder in the powder grinding shell 201.
