A plurality of screw holes are uniformly distributed on the compression roller body 1 along the spiral line direction, and the screw holes can form threaded fit with the salient point connecting parts 2-2.
As shown in fig. 1-4, a plurality of salient points 2 are uniformly distributed on the outer cylindrical surface of the compression roller body 1 along a spiral line; the tops of all the salient points are positioned on the same cylindrical surface.
The salient point 2 consists of a salient point working surface 2-1 and a salient point connecting part 2-2; wherein the convex point connecting part 2-2 is a thread part on the high-strength hexagon socket head cap screw. The convex point working surface 2-1 is coated on the head of the high-strength hexagon socket bolt; the convex point working surface 2-1 is made of high-strength high-hardness rubber, the hardness of the convex point working surface is 82 degrees, and the tensile strength is 18 Mpa.
The salient points 2 are made by adopting a steel glue compounding process; the steel-rubber composite process is characterized in that the high-strength hexagon socket bolt is subjected to surface treatment and then is integrated with the convex point working surface 2-1 through thermal vulcanization, and the high-strength hexagon socket bolt cannot fall off and crack under the condition of high-strength frequent compression.
The convex working surface 2-1 may be spherical, hemispherical, cylindrical or truncated cone-shaped. Fig. 3 shows a bump structure, in which a bump working surface 2-1 is a cylindrical structure, and a bump connecting portion 2-2. Fig. 4 shows another bump structure, in which the bump working surface 2-3 is a hemispherical structure, and the bump connecting portion is 2-4. The bump structures in fig. 3 and fig. 4 are the same except that the structure of the bump working surface is different.
As shown in fig. 5, the lifting distance adjusting mechanism 3 is a two-part structure symmetrically arranged with the salient point press roll as the center, and is connected with both ends of the press roll shaft 4. One part of the lifting distance adjusting mechanism comprises a hand wheel 5, a lead screw 7, a nut 6, a pressing block 8, a pressing plate 9, a pair of pressure springs 10, a bearing 11, a bearing seat 12 and a base 13; wherein:
one end of the screw 7 is provided with a hand wheel 5, and the other end of the screw is fixedly arranged on a pressing plate 9 through a pressing block 8; a nut 6 is screwed on the lead screw 7.
