Polyurethane conveyor belt are broad prospects for future development
Conveyor belt of the latest products is the tooth-belt, timing belt, also known as. It set gear, chains, with the advantage of gear as a whole, with high transmission efficiency, the transmission ratio is accurate, noise, energy saving, convenient maintenance and so on. Although the principle of its transmission as early as 1900 that the emergence of a number of patents, however, after half a century until the beginning of industrialization, since the 80’s has finally become the dominant transmission precision machinery products. Particularly saturated butadiene rubber and polyurethane elastomer manufactured high-precision micro-zone, has entered the high-tech fields. Belt is the original motivation of the motor or engine driving force generated by rotation through the belt pulley from the transmission to machinery and equipment, it is also known as the power band. It is the core of linking mechanical and electrical equipment components, the type of abnormal range, uses a wide range. To several thousands of kilowatts from the giant motor, as small as less than a kilowatt micro-motors, and even home appliances, computers, robotics, precision machinery, etc. can not be separated from belt included. Its most prominent feature is the freedom to speed, drive distance, simple structure, easy replacement. Therefore, from the original machine to the modern automated equipment belts have seen, the product has evolved many times, technology is getting more mature. In recent years, with the rise of high-tech industries, the use of new materials produced by the transmission belt has gradually replaced the traditional products, especially polyurethane belts. At present, both at home and abroad in the field of well-known large companies, both in high-grade polyurethane-based and special micro-with the full development of its leading products. The development of linear positioning, transmission and distribution control markets polyurethane products companies have also launched the polyurethane used in the food industry conveyors. This new product is a 3mm pitch of the transfer belt, and its smaller pitch and soft, making it easy to transfer from one aircraft to be diverted to another conveyor. The flexible polyurethane conveyor belt is better than plastic chain-type conveyor, the conveyor belt and the food industry must be cleaned regularly, it will require a lot of plastic chain belt cleaning work, which can be cleaned easily and polyurethane conveyor belt. Another plastic chain with easy residual bacteria, also need to remove the amount of time spent. New polyurethane conveyor belt will be left a lot of bacteria, and clean up quickly.
Transport belt to deal with the scattering material
The scattering material transport belt is a common problem, the reasons are multi-faceted. But the focus is to strengthen the day-to-day maintenance and repair.
1. Reprinted point spread point spread material reproduced materials primarily in the drop-hopper, trough, etc. Introduction. Such as a serious overload transport belt, the guide trough belt conveyor rubber block rocker covers material damage, guided the design of steel trough Agency belt away from the rubber rocker covers off a long lead materials trough. In the control of the situation on the delivery of capacity, to strengthen the maintenance to be resolved.
2. Au vacant belt at the time of Caesar feed belt interval when Au Au small radius of curvature will have a vacant belt, a belt into a trough at this time the situation changes, as has already left the trough belt idler group, the general slot angle become smaller, so that some material from spreading. Therefore, at the design stage should be as much as possible Au larger radius of curvature to avoid the occurrence of such cases. Such as mechanical loading in the mobile machine, stacker-reclaimer equipment and vehicles in order to shorten the tail will be designed here Au range of non-arc transition, when the belt smaller than the width of selection is easier to spread on the material.
3. Deviation is expected at the time of Caesar Caesar belt at the time of expected deviation due to the two belts at the edge of a high degree of run-time changes in the high side, while the other side of the low side of materials from low-spreading out of the way to deal with adjustment belt deviation.
Introduction of the transport belt
By layers of fabric and rubber by a kind of adhesive tape. Used for the transport of massive, granular, powder or into such items. There are laminated with transport and transport-clad band of two, there are two at the same time and use. Laminated cloth-like layer formed by the hanging plastic canvas, who can bring a soft and flexible for a variety of goods transport. Type of cladding used for the transport of small and difficult to wear with the material transport, such as powder-like substances. Suitable for general transport with little or gradient transport of goods along the horizontal direction. Lift the transport belt can be transported large or vertical direction of the gradient of the items outside the plastic cover, you can up the sink, wet or hard material, such as ore, stone, coke, coal, glass and so on. Can be made with various types of transport connections and there are two kinds of ring-free joints. Generally in accordance with the width of (300 ~ 1500 mm) and fabric layers (3 to 12 layer) is divided into a variety of specifications. By end-use can be divided into cold, heat, oil, food industry, such as transport.
Conveyors are widely used in building materials, chemicals, coal, electric power, metallurgy and other departments for delivery of non-corrosive under normal temperature and no spines in the massive, granular, powder of a variety of materials, such as coal, coke, gravel, cement such as bulk material (material) or as items for transport packing density of 6.5 ~ 2.5t/m3 various massive, granular, such as loose powder-like materials can also be used to transport goods adult.
1, It consists of cotton canvas (CC) or cotton dipped canvas Victoria (VC) by pressing, molding, curing and other processes by refining.
2, the transport belt to adapt to the requirements of the different conditions of use can be made of edge-type package, the edge-type, in the ladder, while different structures such as ladder
