Technical Field

[0001] The utility model belongs to the technical field of screening equipment and relates to a phenolic resin particle screening device. Background Art

[0002] Phenolic resin is also called bakelite or bakelite powder. It is originally a colorless or yellow-brown transparent substance. It is often sold in the market with colorants to appear in red, yellow, black, green, brown, blue and other colors. It has granules and powders. In the processing of phenolic resin products, phenolic resin often has large and small particles, so it is necessary to screen the phenolic resin.

[0003] Patent document with publication number CN208601766U, a novel phenolic resin primary screening device, includes a box body, a feed port and a discharge port are arranged on the box body, and a plurality of screening boxes are staggered on both sides of the box body, the screening box includes an inclined top plate and a horizontally arranged bottom plate, and screening holes are arranged on the top plate; the apertures of the screening holes on adjacent screening boxes increase linearly from top to bottom; a collecting plate is also slidably arranged on the box body, and the collecting plate is inserted into the screening box; a discharge plate and a discharge port are also inclinedly arranged at the bottom of the box body.

[0004] However, the above-mentioned existing ones still have the following shortcomings:

[0005] When adding materials, since the top plate is set at an angle, once too much material is added, it is easy for some materials to fail to pass through the screening holes and roll to the next top plate due to their own weight. Moreover, the material rolls down at a fast speed, and the material stays on the top plate for too short a time, causing some of the materials to fail to pass through the screening holes in time, resulting in low screening accuracy. Utility Model Content

[0006] The utility model aims to provide a phenolic resin particle screening device in view of the deficiencies of the prior art, so as to solve the technical problem of low screening accuracy in the prior art mentioned in the background technology.

[0009] Mounting frame;

[0010] A screening box, the screening box being rotatably mounted in the mounting frame;

[0011] An adjusting rod, the adjusting rod is fixed at one end of the screening box, and the mounting frame is provided with an arc-shaped hole for the adjusting rod to pass through;

[0012] The reciprocating mechanism is fixed on one side of the mounting frame, one end of the adjusting rod extends outside the mounting frame and is connected to the reciprocating mechanism, and the reciprocating mechanism can drive the adjusting rod to move back and forth along the arc hole;

[0013] Two sets of screening components, each set of screening components includes:

[0014] A screening plate, wherein the screening plate is vertically slidably arranged in the screening box, and the screening plate is tiltedly arranged in the screening box;

[0015] A collecting plate, the collecting plate is vertically slidably arranged in the screening box and is respectively located at the lower side of the corresponding screening plate, the collecting plate is obliquely arranged in the screening box, and one end of the collecting plate is respectively fixed to one end of the corresponding screening plate;

[0016] A material chute, which is provided on the inner wall of the screening box;

[0017] A sealing plate is slidably arranged in the material trough of the same group.

The material trough connects the inner cavity of the screening box located at the upper end of the screening plate of the same group and the inner cavity of the screening box located at the lower end of the collecting plate.

[0018] Working principle:

[0019] The screening plate moves up and down along the inner cavity of the screening box and vibrates and screens the material on the upper end of the screening plate. The screened material falls onto the collecting plate through the screening plate, and the adjusting rod is driven to reciprocate along the arc hole by the reciprocating mechanism. The adjusting rod drives the screening box to swing left and right relative to the mounting frame. While the screening box is swinging, the materials accumulated on the screening plate can be continuously spread on the screening plate, thereby avoiding blockage caused by excessive accumulation of materials and improving the screening effect.

The guide plate 18 drives the limit block 14 to move up and down along the limit groove 13, and the two guide blocks drive the two screening plates 3 and the two collecting plates 4 to move up and down.

[0044] like Figure 1 As shown, two mounting plates 19 corresponding to the two blocking plates 5 are fixed to the outer wall of the screening box 2, and a blocking cylinder 20 is fixed to the mounting plate 19.
