Embodiment Construction
[0014] The present invention includes a flat vulcanizing machine 1, a heating circulation system 2, a cooling circulation system 3 and related pipelines and valves.
[0015] The flat vulcanizer 1 is a conventional flat vulcanizer, comprising a frame plate 11, an upper joist 12, an upper hot plate 13, a lower joist 14, a lower hot plate 15, a hydraulic cylinder 16, a hydraulic station 17 and related connection and fixing devices . The upper hot plate 13 and the lower hot plate 15 adopt the low-in and high-out mode of oil inlet, that is, the oil inlet main pipe 18 is arranged at the bottom of the flat vulcanizing machine 1, and the oil outlet main pipe 19 is arranged at the top. Described oil inlet main pipe 18 is connected with oil inlet branch pipe 181, and described oil outlet main pipe 19 is connected with oil outlet branch pipe 191.
[0016] The heating cycle system 2 includes a heat transfer oil furnace 21, an oil outlet pipe I22, an oil return pipe I23, a circulation con...

The invention discloses a repairing device for a PVC / PVG whole-core flame-retardant conveyer belt. The repairing device of the invention overcomes the problems that conventional repairing devices arenot economic and unfriendly to environment. The repairing device is characterized in that a heating circulation system and a cooling circulation system are arranged; the lower part of a press vulcanizer is provided with a main oil inlet pipe, and the upper part of the press vulcanizer is provided with a main oil outlet pipe; the main oil inlet pipe is connected with branch oil inlet pipes; and themain oil outlet pipe is connected with branch oil outlet pipes. According to the invention, the independent heating and cooling circulation systems are adopted, so the heating and cooling proceduresof the hot plate of the vulcanizer are flexibly transformed; the working temperature of the vulcanization hot plate is accurately controlled; and due to closed circulation of heating and cooling mediums, leakage and venting do not occur, and heat energy loss is low. The device has the advantages of simple structure, convenient conversion, precise control, no pollutant emission, energy conservationand environmental protection, effectively solves problems in repairing processes for the PVC / PVG whole-core flame-retardant conveyer belt, and improves the surface quality of the conveyer belt.
Description
technical field [0001] The invention relates to a whole-core flame-retardant conveyor belt repairing device, more precisely to a hot oil carrier heating and cooling PVC / PVG whole-core flame-retardant conveyor belt, light and thin PVC / PVG conveyor belt repairing device. Background technique [0002] PVC / PVG whole core flame retardant conveyor belt is widely used in coal mines due to its excellent flame retardant, antistatic properties and comprehensive strength properties. However, the production process of the whole core flame-retardant conveyor belt in my country has gradually matured and stabilized after years of development, and most of them use scraping or coating processes to achieve continuous production. During the production process of the whole core flame-retardant conveyor belt, due to various reasons, there will be defects such as exposed cloth on the belt surface, air bubbles, lack of glue, bright scars, and defects, which seriously affect the surface quality of ...
