Embodiment Construction

[0037] In order to enable the examiner to have a more detailed and clear understanding of the present invention, the preferred embodiments of the present invention are described in detail below in conjunction with the drawings. These descriptions are only used to illustrate the present invention, not to make any statement on the scope of rights of the present invention. limit.

[0038] Please check image 3 , it is the improved rubber roller device 3 of the present invention, its material is selected as PU, and the micro air holes 31 are formed in the inside which are roughly uniform and densely distributed, so that the physical structure of the rubber roller 3 is a non-slip rough surface with toughness from the inside to the outside , that is, no matter what diameter the rubber roller 3 is worn to, its outer surface is a non-slip rough surface with friction.

[0039] see Figure 4 , which is the implementation process of the above-mentioned improved rubber roller device 3 ...

Abstract

The invention discloses an improved rubber roll device and a manufacturing method thereof. The rubber roll device comprises a rotating shaft (0) and a rubber roll (3) which is coaxially and fixedly arranged outside the rotating shaft (0), wherein the rubber roll (3) is made of PU (Polyurethane) material and air pores (31) are uniformly and densely formed in the rubber roll (3). The manufacturing method of the rubber roll device comprises the following steps of: combining the axis (0) and a forming mould to form a heating mould assembly; mixing and stirring PU prepolymer, a hardening agent and water; filling mixture of a flow 20 into the heated mould; hermetically standing the mould assembly with filled mixture; and taking the rubber roll device comprising the axis (0) and the rubber roll (3) out of the mould. The rubber roll device and the manufacturing method thereof have the advantages that the rubber roll material is PU and the air pores are uniformly and densely formed in the rubber roll, so that the physical structure of the rubber roll is a tough anti-skid rough surface from inside to outside, i.e., the outer surface of the rubber roll is an anti-skid rough surface and has friction force in spite of the diameter of the worn rubber roll.

Description

technical field [0001] The invention relates to an improved rubber roller device and a manufacturing method thereof. Background technique [0002] Rubber rollers, such as anti-slip rubber rollers used in industry, use the friction on the surface of the rubber roller to drive the movement of industrial steel plates, paper in the printing industry, etc., so the surface of the rubber roller must have friction that does not slip and does not damage the driven parts. The performance of the material, the existing rubber roller mainly consists of the following two types: [0003] The first kind of rubber roller is a rubber-rolled rubber roller 1 . Such as figure 1 As shown, the inner side of the rubber part 11 contains obvious mixed particles 12, and the particles 12 are used to achieve the effect of improving friction force, because the formation of friction force is the normal force of the object and the roughness of the surface. Although the friction effect achieved by this r...
