[0002] Polyurethane sieve plate is a mesh product made of polyurethane. Its sieve holes include slits, rectangles, circles and squares. It is mainly used in conjunction with vibrating screens in coal washing plants, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical and other enterprises.

[0003] The utility model, with announcement number CN216705086U, discloses a wear-resistant stainless steel rimmed polyurethane screen plate. By utilizing a structure with different sizes of clamping bolts at the top and bottom, the clamping blocks can be squeezed step by step, forcing the clamping blocks to control the two combined screen plates to be firmly combined. This reduces the problems of loose joints and excessive gaps between the two, further reduces mechanical damage caused by vibration, and extends the service life of the polyurethane screen plate.

[0004] The above technical solution is to open a side groove on the side of the combined screen plate, the groove size of the side groove is larger than the groove bottom size, a U-shaped hole is provided on one side of the side groove, and a chain is provided in the U-shaped hole. One end of the chain passes through the side groove and is provided with a wedge block, and the other end is in contact with the combined screen plate through the clamping block. When the clamping bolt is inserted into the side groove, the wedge block will gradually squeeze the clamping block under the action of the clamping bolt, thereby forcing the combined screen plate to move closer to the middle, further improving the combination firmness between the combined screen plates, and at the same time reducing the problem of mechanical damage due to loose combination; however, the polyurethane screen plate does not have a wear-resistant edging structure, which reduces the damage caused by long-term contact and collision with the material at the edge, or the damage caused to the material by bumping at the edge.
