[0029] like Figure 5 As shown, the vibration mechanism 3 includes a motor 31, and a rotating rod 32 is provided at the output end of the motor 31. The rotating rod 32 passes through the bottom of the screen box 1. Eccentric blocks 33 are sleeved on both sides of the outer wall of the rotating rod 32. Telescopic spring rods 34 are provided around the bottom plate 4. The top side of the telescopic spring rods 34 is connected to the bottom of the screen box 1. The motor 31 rotates to make the eccentric blocks 33 rotate, and then the device vibrates under the action of the elastic force of the telescopic spring rods 34, which speeds up the screening of the color paste.

[0030] like Figure 1 and Figure 3 As shown, fixing grooves 13 are provided on both the left and right sides of the front end of the screen box 1. Mounting plates 52 are fixedly connected to both the left and right sides of the front end of the protective cover 5. The mounting plates 52 are snapped into the fixing grooves 13. Screws 53 are threadedly connected between the fixing grooves 13 and the mounting plates 52. A feed inlet 51 is provided in the middle of the protective cover 5 for feeding color paste. The protective cover 5 can reduce the entry of foreign objects during the screening of color paste. The protective cover 5 is connected to the screen box 1 through the mounting plates 52 and screws 53, which makes it easy to open and separate the screening plate 7.

[0031] like Figure 3 and Figure 4As shown, limiting grooves 12 are opened on the front and rear sides of both ends of the screen box 1, and limiting blocks are slidably connected in the limiting grooves 12. The outer walls of both sides of the screen plate 7 are fixedly connected to the limiting blocks.
