The waste tire treatment line realizes automatic intelligent control

The Nez automatic program-controlled waste tire treatment production line developed by Jiangyin Netzsch Machinery Technology Co., Ltd. passed the expert evaluation organized by the waste rubber comprehensive utilization branch of China Rubber Industry Association last week. The whole production line has small installed capacity, high degree of automation, low investment and low operation cost. In addition to the qb/t 2133 ⑼ 5 extrusion of unplasticized polyvinyl chloride (PVC-U) for indoor decoration at both ends, the whole production line can be connected with an external computer to realize the control of the experimental process and the storage and printing of data. The intermediate section does not need manual operation, and truly realizes automatic intelligent control. At present, dozens of the production lines have been successfully promoted and exported to the United States, Japan, Russia, Ukraine and other countries

Gu Jun, deputy general manager of Jiangyin Netzsch company, introduced that the Nez automatic program-controlled waste tire treatment production line adopts 42 patented technologies and domestic advanced layered tooling to design, which realizes the microcomputer automatic program monitoring of the whole production process, can control the whole production line with one button switch, and intelligently control and automatically adjust the operation of all parts and devices of the production line. The switching power supply is cut off and the power supply is switched on again. The tire crusher of the main machine of the production line adopts two motors with an installed power of 90 kW. The energy consumption from the crushing of waste tires to the production of 60 mesh fine rubber powder is only about 380 kwh/ton, and the energy consumption for the production of 40 mesh rubber powder is 320 kwh/ton, which is about 31% and 24% lower than the average energy consumption of the industry outside the cockpit, respectively, and the output is increased by more than 30%

this production line has two major innovations: first, the whole tire crusher cutter is changed from integral type to detachable type, which solves the problems of difficult replacement, difficult repair and high cost after the cutter head is worn, and shortens the time of repairing or replacing the blade from dozens of days to half a day, greatly improving the equipment efficiency; Second, the rubber block rubbing and cutting machine adopts the working principle of rotary grinding and cutting to form a 360 degree effective working surface, which solves the shortcomings of the currently used double roller crusher and rotary blade crusher, such as high energy consumption, low efficiency, fast blade wear, etc. In addition, the production line also changed single hook single-sided drawing to double hook double-sided simultaneous drawing, and changed hydraulic transmission to mechanical transmission, which can quickly pull out the steel wires on both sides of the tire at the same time, which is three times the processing capacity of single hook drawing

caoqingxin, Secretary General of the waste rubber comprehensive utilization branch of China Rubber Industry Association, said that in 2010, China's waste tires produced about 256 million pieces, weighing 9.4 million tons, of which 3 million tons of recycled rubber and rubber powder were produced, accounting for about 80% of the total utilization of waste rubber. The crushing of waste tires is the first step in the production of rubber powder and reclaimed rubber. It is to separate the steel wire, fiber and other materials in waste tires from rubber to maximize the value. Therefore, the waste tire treatment link is very critical. With the continuous improvement of raw materials, energy and labor costs, enterprises urgently need energy-saving waste tire treatment equipment to realize production automation and efficiency. The automatic program-controlled waste tire treatment line developed by Jiangyin Netzsch just meets this demand
