Technical Field
[0001] This utility model relates to the field of coating production technology, and in particular to a vibrating screening device for raw materials used in coating production. Background Technology
[0002] In the coatings production industry, raw material screening is a crucial step in ensuring the purity and particle size uniformity of raw materials, directly affecting the film-forming quality and application performance of the coatings. With the increasing scale of production, the requirements for raw material purity have become more stringent, leading to the emergence of a vibrating screening device for coatings production. This device aims to solve problems such as screening blockage and low screening efficiency in traditional vibrating screening equipment.
[0003] Currently, in paint production, raw material vibrating screening commonly employs manual screening and ordinary vibrating screening. Manual screening relies on experience to control the screening effect, resulting in extremely low efficiency, unstable screening accuracy, and a lack of versatility. Although ordinary vibrating screens have vibration function, they cannot be optimized for the characteristics of paints, thus affecting screening efficiency.

[0029] Working principle: This raw material vibrating screening equipment consists of an upper frame 3, a middle frame 5, a lower frame 8, and a base 9. The upper frame 3 is the space for screening coarse materials. A coarse screen 14 is installed inside the upper frame 3. The raw material is poured into the screening machine through the feed pipe 1 and falls onto the coarse screen 14. Under the vibration of the vibrating motor 10, the raw material is screened. The coarse material falls from the coarse material pipe 4, and the screened fine material falls onto the fine screen 15. The fine material falls from the fine material pipe 6. A dust cover 2 is installed between the feed pipe 1 and the upper frame 3 to prevent dust from entering. A shock-absorbing spring 7 is fixed between the middle frame 5 and the lower frame 8. The vibrating motor 10 is located inside the lower frame 8. The shock-absorbing spring 7 is located between the vibrating motor and the lower frame 8. The 10 shakes under the action of the screen to achieve the screening effect. Two fixed boxes 16 are set on both sides of the upper frame 3. A motor 17 is fixed inside the fixed box 16. The motor 17 drives the rotating block 18 and the rotating column 19 to rotate quickly. Fixed columns 20 are set on both sides of the motor 17. The swing rod 21 slides inside the fixed column 20. The module 22 blocks the entrance of the fixed box 16. The module 22 is used to block the entrance of the fixed box 16 and drive the push rod 23 to push the raw material on the coarse screen 14. Two ring buckles 12 are set on the upper frame 3 and the middle frame 5 respectively. The fine screen 15 is fixed by the nut 11 and the fine screen 15 is fixed by the nut 2 13.
[0030] In addition, a flow regulating plate is added to the inner wall of the feed pipe 1, and a sealing gasket 24 is installed inside the feed pipe 1. An O-ring 25 and a bearing 26 are added at the connection between the feed pipe 1 and the gate rod 30.

The outer wall of the bearing 26 is fixed to the feed pipe 1, and the inner wall of the bearing 26 is fixed to the gate rod 30. One end of the bearing 26 is connected to a knob 27. By rotating the knob 27, the gate rod 30 can rotate synchronously with the knob 27 under the action of the bearing 26. To achieve the flipping effect, a ring column 31 is fixedly connected to the outer wall of the feed pipe 1. When the gate 28 is open, the feed pipe 1 does not affect the entry of raw materials. When it is necessary to adjust the raw material flow rate, the knob 27 is manually turned to press down the bolt 29. After the knob 27 is turned, there is a hole for the bolt 29 to enter at the position of the bolt 29. The bolt 29 will be inserted into the knob 27 under the action of the spring, fixing the knob 27 and preventing it from turning. At this time, the gate 28 is closed, and the raw material no longer enters, thereby achieving the effect of controlling the raw material flow rate.
