The composite roll consists of roll body, connecting shaft, plastic sealing plate, operating side shaft head, transmission side shaft head, flat key, key pin, socket head cap screws, and water-absorbing holes.
1. After the pulp is uniformly processed in the paper making process, due to the large amount of water contained in the pulp, it needs to be pressed to discharge the water in the molding process of the paper products, and the composite roll is a commonly used dewatering part on the paper making machine, and a large number of water-absorbing holes are arranged uniformly on the surface of it, and it is necessary to use the composite roll to remove the water in the pulp in the process of paper processing and production.
2. By opening water-absorbing holes on the surface of the roll body, a large amount of water contained in the pulp can be adsorbed during the paper making process, while the water-absorbing holes are inverted trapezoidal structure with a wide top and a narrow bottom, which can improve the dewatering efficiency, and the roller body is set up to operate the side axle head and the plastic sealing plate at the connection shaft, which ensures the rotation of the roll body to avoid the impact of the impurities in the pulp on the transmission efficiency of the connection shaft.
3. The composite roll is used in stacked net paper machine, single-length net paper machine without composite roll. Due to the composite roll without rubber coating, so the construction period will be shorter, one and a half months can be.
