Technical Status Of Light Conveyor Belts

Jul 03, 2019

The conveyor belt is the main component of the belt conveyor. The role of the super-carrying material is that the conveyor belt is used as the transportation carrier and has the advantages of safe operation, convenient use, easy maintenance, low freight and continuous operation, and shortened transportation distance. . The light conveyor belt is a fine product in the conveyor belt, which allows the working tension to be less than 50N, has a thin body, good dimensional stability, high tension and bright color. Safe and non-toxic features. Widely used in food, medicine, electronics, tobacco, printing, packaging, wood, textile, building materials, transportation, postal, logistics and other industries. It is used for the conveyance of articles, bags, bulk materials, and the production of water in the factory and the processing of agricultural and sideline products. It is also called the process belt. During the fifteenth period, the domestic light conveyor belt production achieved breakthrough progress and gradually occupied an important position in the conveyor belt industry. The variety specifications have reached hundreds of varieties and have been widely used in many fields.

  1 Lightweight conveyor belt structure:

  The composition of the light conveyor belt includes a cover layer, a skeleton layer, a bottom layer, and a sandwich layer when the skeleton is two layers or more.

The covering layer is the conveying surface of the light conveyor belt. According to the nature of the conveying material, it should have good heat resistance, oil resistance, water resistance, aging resistance, corrosion resistance, static conductivity, non-toxicity, etc. , rubber and plastic blend, PVC, TPU, TPE, polyamide and fabric.

The core fabric of the skeleton layer is generally one to three layers, and the most common is two layers. The warp yarn material of the fabric is mostly high modulus low stretch polyester filament, and commonly used are 1000D and 1500D. The weft yarns are polyester filaments, polyester monofilaments, and nylon filaments. When a transverse rigidity is required for transportation, a polyester fabric having a weft yarn of polyester monofilament is used as a skeleton layer. The fabric structure has plain weave, twill and straight weft. To ensure good adhesion to the cover layer and the interlayer. The fabric needs to be activated or immersed.

The bottom layer is the transmission surface of the light conveyor belt. Whether it is the plate support or the roller support, it is in contact with the support and the transmission system, generally the skeleton fabric, and some of the light conveyor belt bottom layer is the same coating material as the cover layer or the interlayer material. The material of the interlayer may be the same or different from the cover layer, and the thickness of the light conveyor belt is generally between 0.5 and 4 mm, and the thickness is not more than 7 mm.

  2 light conveyor belt production and processing technology

  Whether it is a rubber-type light conveyor belt or a resin-based light conveyor belt, the production and processing methods produced are all rolled products, which need to be processed after being supplied to the user, that is, cut into a certain length, width and carry out. Ring joint processing. According to the material of the cover layer, the ring joint method has bevel grinding, tooth welding, button fastening and the like. The light conveyor belt that is connected to the head requires uniform thickness and smooth surface to ensure accurate material delivery.
