I produced the pattern conveyor belt by Face plastic cover for the pattern shape and the angle of non-face conveyor and plastic cover with a core composed of plane. Depending on the transportation of materials and different transmission angle size, shape and height requirements are different patterns. Cross conveyor belt surface have higher body rib belt, the pattern is divided into high, medium and low three, according to the arrangement pitch of each pattern can be divided into sparse, dense form. Common varieties are: chevron conveyor belt, eight-shaped conveyor, conveyor fish bone, U-shaped conveyor, cylindrical conveyor, pitting conveyor belt, embossed conveyor belt. Or according to user requirements for less than 30 degrees angle of powdered, granular pattern conveyor belt, and the outer surface of the cylinder block materials processing errors, sticky material or wear caused by uneven sizes in diameter, the diameter of the belt will larger side of the deviation. The so-called "run do not run large small." Situation as shown in its force of four: the belt traction Fq to produce a larger diameter side of the mobile component Fy, component Fy in the role of conveyor shifted. In this case, the elevator conveyor belt, the solution is to clean the drum surface sticky materials, conveyor belts, processing errors and uneven wear down to be replaced by reprocessed plastic bag processing environment is different, light conveyor belt, divided into ordinary rubber conveyor belt, heat-resistant rubber conveyor belt, cold rubber conveyor belt, rubber conveyor belt acid, oil and rubber conveyor belt, food conveyor models. Wherein the plastic cover on ordinary rubber conveyor belt conveyor and food minimum thickness of 3.0mm, under the plastic cover a minimum of 1.5mm; resistant conveyor belt, heat resistant conveyor belt covered with a minimum thickness of plastic 4.5mm, under the plastic cover a minimum of 2.0 mm. Depending on usage environment can be used to increase the vertical thickness of 1.5mm plastic cover resistant conveyor belt service life, the whole of the industrial belt of Central Asia (certification), the conveyor belt is provided by a full industrial belt Ltd. Qingdao Central Asia. Qingdao Central Asia-wide industrial belt Ltd. (www.zhongyaquan.com) is in Qingdao, Shandong belt leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Full industrial belt in Central Asia led the staff warmly welcome all inquiries negotiations to create the whole of the industrial belt of Central Asia a brighter future.
