Continuous microwave curing production line for rubber cables

Abstract

The invention discloses a continuous microwave curing production line for rubber cables, which comprises a drive paying out machine, a horizontal storage hub, an upper tractor, a co-extrusion die, an automatic upper sealer, a high-temperature setting device, a microwave curing section, a hot-air curing section, a midpoint controller, an automatic lower sealer, a cooling section, a tractor and a cable machine which are sequentially connected. The continuous microwave curing production line provided by the invention not only has a rational design and a unique structure, but also has no pollution with big social benefit, and saves energy since the plastic generates heat directly by absorbing the microwaves without being heated by using equipment, thus the continuous microwave curing production line has the advantages of high energy use ratio, fast temperature rise, short desulfuration time, capability of continuous automatic production, reduced labor load of workers, improved production environment, good product property, and allowed dosage of permeability which is 15% larger than that of the conventional method.

Description

Technical field [0001] The invention relates to a continuous microwave vulcanization production line for rubber cables. Background technique [0002] Rubber vulcanization is the key and final process for the molding of rubber products. Various methods can be used for rubber vulcanization. The traditional method is to use steam or far-infrared heating to vulcanize the rubber. However, since the heating temperature is slowly conducted from the outside of the medium to the inside, , because the rubber material is a poor thermal conductive material. For rubber, heating depends on the inward heat transfer rate from the surface of the material, which is very slow. Most of the time is spent on letting the rubber reach the vulcanization temperature (the vulcanization time of car tires is 3 hours), so The heating time is long, the efficiency is low, and the vulcanization uniformity is not good. In particular, the steam heating process uses magnesium silicate (talcum powder) to elimin...

[0002] Rubber vulcanization is the key and final process of rubber product molding. Various methods can be used for rubber vulcanization. The traditional method is to vulcanize the rubber by steam or far-infrared heating. , because the rubber material is a poor heat-conducting material, the heat transfer rate from the surface of the material to the inside of the rubber is very slow, and most of the time is spent on letting the rubber reach the vulcanization temperature (the vulcanization time of car tires is 3 hours), so The heating time is long, the efficiency is low, and the vulcanization uniformity is not good. In particular, the steam heating process uses magnesium silicate (talcum powder) to eliminate rubber adhesion, resulting in dust in the rubber production workshop, and the dust content in the air far exceeds the standard stipulated by the national environmental protection department. , seriously pollute the environment, cause harm to human health, and it is difficult to maintain, and the overall vulcanization state of the rubber is not ideal. Uniform phenomenon, it is difficult to further improve the quality, and the process is complicated, wastes energy, labor intensity is high, it is difficult to realize linkage production, and high-density rubber products cannot be obtained
