Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coating processing, especially relates to a powder screening device for coating processing. BACKGROUND

[0002] The powder screening device for coating processing is a key equipment for screening and grading powder raw materials in the coating production process. The main function of this kind of device is to separate particles of different particle sizes from a mixture to ensure that the quality of the final product meets specific standards and requirements.

[0003] However, the existing technology has some problems: the existing powder screening device for coating processing often uses a horizontal screen to screen the coating powder. For large-volume coating, the screen needs to be removed after shutdown to take out the coating for regrinding and then screening, which affects the screening efficiency. Moreover, static electricity is generated when the coating powder comes into contact with the screen, causing the coating powder to adhere to the screen and not to fall off easily. Therefore, we propose a powder screening device for coating processing. SUMMARY

[0004] To overcome the shortcomings of the prior art, the powder screening device for coating processing is provided. The large-volume coating is transported to the pulverizing device main body through the inclined screen, crushed, and then fed into the feed hopper for screening. This can achieve cyclic screening without shutdown. At the same time, the driving motor drives the cam to rotate, which is intermittently in contact with the lower end of the jumping push plate to push it, achieving the up-and-down vibration of the screen. The screen will hit the cam during the falling process, and the impact force will shake off the powder adhering to the screen, thereby saving the time for cleaning the screen and improving the efficiency of coating powder screening.

[0005] The utility model discloses a powder screening device for coating processing, which comprises an outer shell main body, a feed hopper fixedly connected to the upper side of the outer shell main body, a screen obliquely arranged below the feed hopper, the screen being rotatably connected to the inner side of the outer shell main body near one end of the feed hopper, a jumping push plate elastically connected to the lower side of the screen far from the feed hopper, a driving motor arranged below the jumping push plate, the driving motor being fixedly connected to the inner side of the outer shell main body, a cam fixedly connected to the output shaft of the driving motor, and a pulverizing device main body fixedly connected to the side of the outer shell main body far from the feed hopper.

[0006] Optionally, an observation port is formed in the front side of the outer shell main body, and a discharge hole is formed in the outer shell main body near the jumping push plate, the discharge hole being in communication with the inner side of the pulverizing device main body.

[0007] Optionally, the conveying slide plate is obliquely arranged, and the obliquely higher end of the conveying slide plate is close to the obliquely lower end of the screen.

[0008] Optionally, the conveying slide plate is obliquely arranged, and the obliquely higher end of the conveying slide plate is close to the obliquely lower end of the screen.

[0009] Optionally, the spring is arranged between the jumping push plate and the bottom of the obliquely lower end of the screen, and the jumping push plate and the screen are elastically connected through the spring.

[0010] Optionally, the arc-shaped groove is arranged in the bottom of the jumping push plate, and the cam 7 is slidingly arranged in the arc-shaped groove.

[0011] Optionally, the conveying slide plate is in a V-shaped type, and the middle groove of the conveying slide plate is vertically corresponding to the middle gap of the two groups of crushing roller cylinders.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] The driving motor drives the cam to rotate, and the screen is vibrated up and down by the intermittent contact and pushing of the lower end of the jumping push plate. The screen will impact the cam during the falling process, and the impact force will shake off the powder adhered to the screen, thereby saving the time for cleaning the screen and improving the efficiency of the paint powder screening.
