Modified asphalt coiled material forming and thickness control device capable of preventing tire bases from being broken by blowing

Abstract

The utility model discloses a modified asphalt roll molding thickness controller for preventing a tire base from being scraped to be broken. The molding controller comprises two thickness adjusters which are oppositely arranged up and down. The molding thickness controller is characterized in that the two thickness adjusters are of wedge structures; the front ends of the two thickness adjusters are oppositely arranged; a first gap is arranged between the front ends of the two thickness adjusters; the first gap serves as the input end of the molding thickness controller; a second gap is arranged between the rear ends of the two thickness adjusters; the second gap serves as the output end of the molding thickness controller, and the first gap is smaller than the second gap. The molding thickness controller has the advantages that tire base cloth can be prevented from being scrapped to be broken; and coated tire roll is relatively smooth and relatively even in thickness.

Description

technical field [0001] The invention relates to a modified asphalt coil manufacturing equipment, in particular to a modified asphalt coil forming thickness control device for preventing tire base from being broken. Background technique [0002] At present, there are three main categories of waterproofing membranes sold in the Chinese market, namely: 1. Modified asphalt waterproofing membranes; 2. Polymer plastic sheets; 3. Rubber waterproofing membranes. Among them, the modified asphalt waterproof membrane occupies a dominant position in the application. In 2010, the output reached 400 million square meters, of which self-adhesive membranes accounted for 30%, and grew at a rate of 50% every year, and other ordinary hot-melt membranes accounted for 60%. %, with an annual growth rate of around 15%. There are three construction methods for these membranes in the general application engineering construction process, namely: 1. Heat the molten asphalt with a gasoline blowtorch a...

Problems solved by technology

[0004]The forming thickness control device includes two thickness adjusting rollers arranged up and down oppositely. The conventional upper and lower thickness adjusting rollers are both round rollers. The thickness of the middle and both sides of the coil is not the same, often appearing the middle-thick bracket type "()" or the middle-thin two-side thick back-bracket type ") (" defects, and the impurity, particles, and hard blocks in the coating material are prone to enrichment and blockage Between the two round rollers, the tire base fabric is broken
