How to distinguish between PVC conveyor belt and PU conveyor belt? I believe that many customers are not able to distinguish it directly, and some customers will question: Why is the PU conveyor belt that obviously cost several times to buy not durable? It is not uncommon for this situation, because the two belts of PVC conveyor belt and PU conveyor belt are visually similar, but it is relatively difficult to identify for consumers who do not understand this industry. The editor can tell you a simple trick to distinguish these two materials: if you touch these two conveyor belts with your hands, you will find that PU conveyor belts are softer than PVC conveyor belts. In response to this situation, the following are some of the better distinguishing techniques so that everyone can better distinguish the two conveyor belt materials: 1. Elasticity of conveyor belt PVC conveyor belt rebounds slowly after folding, PU conveyor belt rebounds quickly 2. Scratch resistance of conveyor belt The...

For more than half a century, the technical development of the world transmission belt has gone through the following stages: First, from the perspective of the materials used for transmission belts, rubber has evolved from natural rubber to synthetic rubber, and further expanded to special synthetic rubber CSM, HNBR: the skeleton material has been expanded from cotton fiber to rayon, polyester, nylon, glass fiber, For details of steel wire and aramid, see Table 2. Goods. In order to improve the durability of the V-belt , since the 1960s, there has been a cutting triangle belt, which has no wrapping on the side, and it has very good bending fatigue resistance. It has replaced most of the wrapping triangle belt. On the other hand, after entering the 1980s, the V-shaped flat belt combined with the V-shaped belt has been rapidly developed. Due to its excellent performance and a sharp increase in output, it has now partially replaced the cutting V-belt. Shortly thereafter, wedge-shaped V-b...

Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel and other industries where the transportation distance is short and the transportation volume is small. The conveyor belt uses multi-layer rubber cotton canvas as the skeleton, and the surface is covered with a rubber material with good performance, which is made by vulcanization. All conveyor belts must be connected in a ring before they can be used, so the quality of the conveyor belt joint directly affects the service life of the conveyor belt and whether the conveyor line can run smoothly and smoothly. Common methods for conveyor belt joints include mechanical joints, cold bonded joints, and hot vulcanized joints. Conveyor belts include ordinary cotton canvas conveyor belts, nylon (NN) conveyor belts, polyester (EP) conveyor belts, large inclination (wavy rib) conveyor belts, skirt partition conveyor belts, endless conveyor belts, patterned conveyor belts, stoppers Water belt, PVC or PVG whole core flame...

Rubber timing belt transmission is composed of an endless belt with equal-distance tooth shape on the inner peripheral surface and wheels with corresponding anastomosis. It combines the advantages of belt drive, chain drive and gear drive. When rotating, the power is transmitted through the meshing of the toothed groove of the wheel. The transmission dragon synchronous belt drive has an accurate transmission ratio, no slip, can obtain a constant speed ratio, smooth transmission, can absorb vibration, low noise, large transmission ratio range, generally up to 1:10. The allowable linear speed can reach 50M/S, and the transmission power is from several watts to hundreds of kilowatts. The transmission efficiency is high, generally up to 98%, the structure is compact, suitable for multi-axis transmission, no lubrication and no pollution, so it can work normally in places where pollution is not allowed and the working environment is harsh. Transmission products are widely used in various typ...

01 When to use timing belt Long wheelbase, up to 10m low noise The transmission accuracy is relatively high (generally up to 20, if you want higher, you need to add closed-loop feedback) Speed ​​<50m/s Power P<300kw Transmission ratio i<10 Temperature -30-90 degrees Celsius 02 Know the synchronous belt If you want to find more synchronous belt parameters, please click synchronous belt parameters 1 Tooth profile Trapezoid Applicable occasions: occasions with low speed and low power transmission. Advantages: high transmission accuracy and cheap Disadvantages: The tooth root is easy to stress concentration, so the load capacity is low; the noise and vibration are large Arc tooth Applicable occasions: small tooth pitch and small backlash, more suitable for positioning and high torque Advantages: high transmission accuracy, large transmission torque, low noise, can prevent interference during tooth meshing Disadvantages: expensive 2 Material Rubber timing belt Use occasion: mainly ...

The deviation of the conveyor belt is the most common fault of the belt conveyor. Its timely and accurate treatment is the guarantee of its safe and stable operation. There are many phenomena and causes of deviations, and it is necessary to adopt different adjustment methods according to different deviations and reasons to effectively solve the problem. This article is based on many years of field practice, from the perspective of users, using mechanical principles to analyze and explain the causes and treatment methods of such failures. The axis of the head-driven roller or tail-redirecting roller is not perpendicular to the conveyor centerline, causing the conveyor belt to deflect at the head roller or tail-redirecting roller. When the roller is skewed, the tension of the conveyor belt on both sides of the roller is inconsistent, and the traction force Fq received in the width direction is also inconsistent, which is an increasing or decreasing trend. This will cause the conveyor bel...

In addition to offering 3-D visualization for digitally rendered items, rapid prototyping can be utilized to test the efficiency of a component or product design before it is manufactured in larger portions. Testing could have more to do with the shape or measurement of a design, somewhat than its strength or durability, as a result of the prototype will not be made from the same materials as the ultimate product. Jevny is a well-established company headquartered in Shenzhen and Dongguan Cities. Guaranteed high quality elements at consistently low prices and quick lead instances,we remodel product concepts into production realities. We are in a position that can assist you with every thing from concept to finished merchandise – which are based in your needs and targets. This kind of prototyping entails utilizing a CNC machine to make a working mannequin of a part directly from a CAD program. Not to say the fabric used that isn't what can be used in giant-scale production. 3D Proto...
