A modified asphalt coil forming thickness control device to prevent tire base from being scraped

Abstract

The invention discloses a modified asphalt coiled material forming and thickness control device capable of preventing tire bases from being broken by blowing, The forming and thickness control device comprises two thickness-adjusting devices which are arranged in an up-and-down opposite mode. The forming and thickness control device is characterized in that the two thickness-adjusting devices are both of a wedged structure, the front ends of the two thickness-adjusting devices are arranged oppositely to each other, a first gap is arranged between the two thickness-adjusting devices, the first gap is the input end of the forming and thickness control device, a second gap is arranged between the rear ends of the two thickness-adjusting devices, the second gap is the output end of the forming and thickness control device, and the first gap is less than the second gap. Due to the wedged structures, a tire-containing coiled material after being provided with a coating material is smoother, and more uniform in thickness. A thickness-adjusting roller can be made of engineering ceramics, so that the heat resistance and wear resistance of the device are better. Therefore, the forming and thickness control device disclosed by the invention has the advantages that the device can prevent tire bases from being broken by blowing; the tire-containing coiled material after being provided with the coating material is smoother, and more uniform 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
