Conveyor belt is the main part of belt transportation, overload material, the use of conveyor belt as a transport carrier compared with other modes of transport has safe operation, convenient use, easy maintenance, low freight, can achieve continuity, shorten transport distance, etc. Light conveyor belt is the best product in conveyor belt. Its working tension can be less than 50N/mm. The fuselage is light and thin. It has good dimensional stability, high tension and bright color. It is safe and non-toxic. It is widely used in food, medicine, electronics, tobacco, printing, packaging, wood, textile, building materials, transportation, postal, logistics and other industries. It is used for the transportation of goods, bagging and bagging, bulk materials, internal production processes and processing of agricultural by-products, so it is also called processing belt. During the Tenth Five-Year Plan period, breakthroughs have been made in the production of light-duty conveyor belts in China, and they have gradually occupied an important position in the conveyor belt industry. Hundreds of varieties and specifications have been adopted, which are widely used in many fields.

　　1. Light conveyor belt structure:

　　轻质输送带的组成包括覆盖层、骨架层、底层和骨架在两层以上的夹层。

　　The composition of light conveyor belt includes the interlayer of overburden layer, skeleton layer, bottom layer and skeleton above two layers.

　　覆盖层为轻型输送带表面。根据输送物料的性质，应具有良好的耐热性、耐油性、耐水性、耐老化性、耐腐蚀性、静电导电性、性等。材料包括橡胶、橡塑共混物、PVC、TPU、TPE、聚酰胺、织物等。

　　The covering layer is the surface of 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, electrostatic conductivity, non-toxicity and so on. Materials include rubber, rubber-plastic blends, PVC, TPU, TPE, polyamide, fabrics and so on.

　　骨架层的核心结构通常是一到三层，常见的是两层。织物的经纱材料以涤纶长丝为主，模具高，伸长率低，常用的经纱为1000D和1500D。纬纱有涤纶长丝、涤纶单丝和锦纶长丝。当需要横向刚性时，选择涤纶单丝纬纱作为框架层。织物结构按平纹、斜纹和直经纬的编织风格而定。确保覆盖层与中间层之间有良好的粘合力。织物需要活化或浸渍。

　　The core structure of skeleton layer is usually one to three layers, and the most common is two layers. The warp yarn material of the fabric is mainly polyester filament with high die and low elongation. The commonly used warp yarns are 1000D and 1500D. Weft yarns include polyester filament, polyester monofilament and nylon filament. When transverse rigidity is needed, polyester monofilament weft is selected as frame layer. The fabric structure is determined by plain weave, twill weave and straight warp and weft weaving style. Ensure good adhesion between the overburden and the middle layer. Fabrics need to be activated or impregnated.

　　底层为轻型输送带的传动面。无论是板支承还是辊支承，都与支承和传动系统相接触。一般来说，它是骨架织物。

　　The bottom layer is the transmission surface of the light conveyor belt. Both plate support and roll support are in contact with the support and transmission system. Generally speaking, it is a skeleton fabric.

　　所述夹层材料可与所述覆盖层相同或不同。

　　The sandwich material can be identical or different from the covering layer.

　　轻型输送带厚度一般为0。5-4mm之间，大厚度不超过7mm。

　　The thickness of light conveyor belt is generally 0. Between 5 and 4 mm, the maximum thickness is not more than 7 mm.

　　轻型输送带生产加工技术

　　Production and Processing Technology of Light Conveyor Belt

　　无论是橡胶轻输送带还是树脂轻输送带，其生产加工方法所生产的产品均为轧制产品，这些产品提供给用户后需要加工，即切成一定长度、宽度和环形接头加工。根据涂层材料的不同，环形接头有锥面磨削、齿形焊接、钉扣搭接等。连接头好、重量轻的输送带要求厚度相同、表面平整，保证物料的准确输送。

　　Whether rubber conveyor belt or resin conveyor belt, the products produced by its production and processing methods are rolling products. These products are provided to users for processing, that is, cut into a certain length, width and ring joint processing. According to the different coating materials, the annular joints have taper grinding, tooth welding, nail lapping and so on. Conveyor belts with good connection and light weight require the same thickness and smooth surface to ensure the accurate transportation of materials.
