Novel vulcanization pressurizing plate, vulcanizer, rubber sheet for conveyor belt joint and conveyor belt connecting method

Abstract

The invention relates to a novel vulcanization pressurizing plate, a vulcanizer, a rubber sheet for a conveyor belt joint and a conveyor belt connecting method. In order to solve the problems that in the existing conveyor belt joint technology, pressure intensity control is not precise, and a vulcanized rubber joint is low in strength and poor in quality, the invention provides a novel vulcanization pressurizing plate. The novel vulcanization pressurizing plate comprises a square pressurizing frame, a base plate, a stainless steel pressurizing inner container and a lifting plate, wherein the base plate is fixedly connected to the lower edge of the square pressurizing frame to form an open square pit; the stainless steel pressurizing inner container is arranged in the square pit; the lower surface of the lifting plate is pressed on the stainless steel pressurizing inner container; the lower edge of the periphery of the lifting plate is embedded in the square pit; the stainless steel pressurizing inner container is in a flat square shape; the side wall of the stainless steel pressurizing inner container is further communicated with a pressurizing pipe; and the outer end of the pressurizing pipe penetrates through the square pressurizing frame and then is connected to a matched high-pressure pump through a valve. The novel vulcanization pressurizing plate, the vulcanizer, the rubber sheet for the conveyor belt joint and the conveyor belt connecting method overcome the defects in the prior art, the rubber at the the conveyor belt joint is high in hardness, high in tensile strength and very tough, and the service life of the conveyor belt is greatly prolonged. The novel vulcanization pressurizing plate, the vulcanizer, the rubber sheet for the conveyor belt joint and the conveyor belt connecting method are widely applicable to various coal mines.

Description

technical field [0001] The invention relates to a novel vulcanization pressure plate, a vulcanizer, a rubber sheet for a conveyor belt joint and a conveyor belt connection method. Background technique [0002] At present, different industries in China usually use the following methods to deal with the problem of degumming of conveyor belt joints. [0003] The first method is cold bonded joints. The connection method is to polish, clean, and dry the prepared joints, and then apply adhesive (the main glue and curing agent are prepared on site according to the proportion of the manufacturer), and the joints are bonded, and then rolled with a roller or hand hammer to make them compact. Curing at room temperature, the conveyor belt is ready to use. This bonding method saves time and effort, is easy to operate, does not require a heat source for bonding, and uses fewer tools on site. It can meet the requirements for conveyor belts with short distances or small slopes, and the jo...

Problems solved by technology

The structure of the bonding vulcanizer disclosed in this invention still mentions a water pressure plate, but does not disclose the specific structure of the water pressure plate. When vulcanizing, the output water pressure of the pressurized pump connected to the water pressure plate is used as the control parameter. The water pressure cannot be equal to the vulcanization pressure. It is not convenient to accurately control the vulcanization pressure. If the pressure control is too low, it is not easy to exhaust. If the pressure control is too high, it is easy to over-extrude the rubber, resulting in the thickness of the conveyor belt being too thin after vulcanization.
