Research And Development Of New Light Conveyor Belt

Light conveyor belts are used in printing and finishing process and plate transportation, but the printing and finishing strong with a low light conveyor belt and the longitudinal elongation and deformation of existing printed shift problem, and the steel conveyor belt with a light fitting weak at the existence of poor performance and the existence of plate deformation of the interface problems. The existing equipment is developed to take advantage of high-performance, low cost, easy processing, high stability for light-weight conveyor belt, the paper coating on the reinforcing material and the large number of tests carried out research, and ultimately to the successful development of Kevlar woven fabric as the reinforcing materials High Tenacity Low Shrinkage light conveyor belt and the large-diameter seamless circular woven fabrics as reinforcing materials for seamless ring-type light-weight conveyor belt, as follows:(1) For the aramid yarn processing difficulties, weak anti-fatigue performance, rational design of aramid yarn twisting, winding and weaving process of the process parameters, the success out of the warp yarn woven aramid filament, ultra-low shrinkage polyester weft monofilament aramid woven fabric.(2) For the low density of Kevlar woven fabric surface, adhesion strength and small properties, the shape of Kevlar woven fabric pretreatment, the shear external force, the fabric deformation decreases, yarn evenness and the degree of orientation increased, to avoid Weak fabric appears to improve the Kevlar fabric with PU peel performance.(3) For resistance to compression and poor performance Kevlar, a fabric through a fabric glue and three small scale pilot three plastic, designed three fabric three plastic processing technology, so that the surface of Kevlar protection while reducing the cost of light conveyor belt The successful development of materials with high strength aramid fiber for the skeleton type of lightweight low stretch belt. (4) For the width of the existing small loom, weaving the warp and weft can not meet the low density transport plate seamless conveyor belt frame of light material, paper blankets, weaving through the modification and small-diameter seamless circular light Conveyor belt of trial and error, success weaving a seamless width of 6.1m of fabric; combination of coating process, successful development of large-diameter seamless circular light conveyor belt.The test, developed in this paper to Kevlar material for the skeleton type of high strength and low elongation at 1% extension of light under the belt breaking strength greater than 40N/mm, to meet the requirements of dyeing and printing; the development of large-diameter circular seamless light transfer Weak force with more than 50% higher performance and achieve consistent interface to meet the transportation requirements of steel.
