Description

Technical Field

[0001] The utility model relates to the technical field of rubber powder production equipment, in particular to a high-efficiency coarse screening device for rubber powder production. Background Art

[0002] Rubber powder refers to the powdered rubber material obtained by crushing waste rubber products. The finer the rubber powder, the better the performance. The finer the rubber powder, the better the tensile strength, elongation and abrasion. Rubber powder can be used in building materials, such as paving sports fields, laying track beds, etc. Using a small amount of rubber powder for the tread can reduce the dynamic heat generation life of the tire.

[0003] After the production is completed, the rubber powder needs to be graded according to the particle size. The above steps are mostly carried out with the help of a rotary vibrating screen. When using a rotary vibrating screen to grade the rubber powder, in order to facilitate the collection of the graded rubber powder, the staff usually places a box under the several discharge pipes of the rotary vibrating screen to collect the graded rubber powder. When the box is full of rubber powder and replaced with an empty box, some rubber powder will be scattered on the ground in the gap, which requires the staff to carry out subsequent collection work in piles, which adds steps and increases labor costs.

[0028] Working principle of this utility model:

[0029] When the box containing the rubber powder is almost full and needs to be replaced with an empty box during the process of using the rotary vibrating screen to grade the rubber powder, a force is first applied to the tube cover 304 to separate the first Velcro 305 and the second Velcro 306, and then the strip limit block 209 is rotated to a horizontal state. At this time, the blocking column 210 cannot limit the L-shaped rod 208. Then, the turntable 205, the rotating rod 203 and the flow regulating plate 204 are driven by the L-shaped rod 208 to rotate counterclockwise. When the rubber strip 207 is tightly fitted with the inner wall of the flow regulating box 201 and the L-shaped rod 208 moves to one side of the other blocking column 210, the strip limit block 209 is rotated to be flush with the long rod part of the L-shaped rod 208.

After the adjustment of the flow regulating plate 204 is completed, the rubber powder will flow into the hopper 301 and the temporary collection bag 302 along the inclined surface of the flow regulating plate 204 for temporary collection. After that, the empty box can be replaced. After the replacement work is completed, the discharge pipe 303 is placed in the empty box and the pipe cover 304 is removed. The rubber powder in the temporary collection bag 302 will flow into the box through the discharge pipe 303. After the rubber powder in the temporary collection bag 302 has flowed out, the pipe cover 304 is screwed on the discharge pipe 303 again and the discharge pipe 303 is taken out of the box, thereby avoiding the situation where the rubber powder is scattered on the ground, eliminating the need for pile collection work, and reducing labor costs.
