Description

Technical Field

[0001] The present invention relates to the technical field of rubber processing roller pressing equipment, and more specifically, to a rubber processing roller pressing machine. Background Art

[0002] The main material of rubber is raw rubber, which has no elasticity or low elasticity, and is very brittle and easy to break. Obviously, raw rubber cannot meet industrial requirements. Therefore, in the rubber processing technology, additives such as sulfide need to be added to the raw rubber to improve the elasticity and ductility of the rubber product. In the production process of rubber products, it is necessary to prepare it into the required thickness and curvature according to the size model of the product to be produced. At present, the main rolling equipment is used for rolling; Existing rubber rolling devices, such as a rubber processing rolling machine with publication number CN221161125U, include a material after preliminary extrusion being placed on a roll, passing between two sets of transition wheels, and then placed between an upper pressing roller and a lower pressing roller, during which the pushing cylinder drives the guide sleeve to make reciprocating linear motion along the guide column, and at the same time, under the action of friction, the rubber mixture drives the transition wheel to rotate around the fixed column, thereby completing the extrusion of both sides of the rubber, and after the upper pressing roller and the lower pressing roller are rolled once again, the upper material blocking plate and the lower material blocking plate block the material between the extrusion rollers below, and the next rolling mixing is performed, thereby improving the efficiency of rubber extrusion mixing, and also ensuring that the rubber and sulfide are mixed more evenly, thereby increasing the service life of the rubber; However, the existing rubber rolling device cannot limit the edges of rubber products of different sizes during use, so that the edges of the material are easily protruded outward due to excessive pressure during the extrusion process, resulting in the edge surface being not flat enough, requiring subsequent secondary trimming.
