Intelligent natural rubber machining system and intelligent natural rubber machining method thereof

Abstract

The invention provides an intelligent natural rubber machining system and an intelligent natural rubber machining method of the intelligent natural rubber machining system. A first roller group and asecond roller group are arranged and can calender the rubber twice; and meanwhile, the axis of the first roller group and the axis of the second roller group are perpendicular. A first conveyer belt and a second conveyer belt convey the rubber, the rubber calendered by the first roller group is conveyed by the first conveyer belt and the second conveyer belt to the second roller group, the secondroller group calenders the rubber in the other direction, and the calendering directions of the first roller group and the second roller group are perpendicular. In this way, the calendering effect generated in the whole calendering process can be lightened, the quality of rubber products is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to an intelligent natural rubber processing system and method thereof. Background technique [0002] The processing technology of natural rubber generally includes the processes of mastication, mixing, calendering, molding and vulcanization, among which calendering refers to passing the plasticized rubber close to the viscous flow temperature through a series of horizontal roller gaps rotating in opposite directions to make the rubber Under the action of extrusion and extension, it becomes a thin sheet product with a certain thickness, width and smooth surface. During the calendering process, when the rubber passes through the gap between the calender rollers, it will be subjected to both shear force and tensile stress. Polymer It will be oriented along the calendering direction, so that the longitudinal tensile strength of the calendered film is greater than the transvers...

Problems solved by technology

[0002] The processing technology of natural rubber generally includes the processes of mastication, mixing, calendering, molding and vulcanization, among which calendering refers to passing the plasticized rubber close to the viscous flow temperature through a series of horizontal roller gaps rotating in opposite directions to make the rubber Under the action of extrusion and extension, it becomes a thin sheet product with a certain thickness, width and smooth surface. During the calendering process, when the rubber passes through the gap between the calender rollers, it will be subjected to both shear force and tensile stress. Polymer It will be oriented along the calendering direction, so that the longitudinal tensile strength of the calendered film is greater than the transverse tensile strength. When the temperature changes greatly, the size in each direction will change, and the longitudinal direction will shrink. The most serious is cracking. At this time, expansion occurs in the transverse and thickness directions, which leads to problems in the quality of rubber products and reduces the service life.

[0003] Factors affecting the calendering effect include calendering temperature, roller speed and speed ratio, roll gap stock, product thickness, material properties, etc. The existing methods to solve the calendering effect are generally to control the roller speed or control The calendering temperature has a poor effect on reducing the calendering effect, and the temperature and rotation speed are greatly affected, which is difficult to control
