In the process of conveying materials stably, the speed sensor and the load sensor provide two kinds of signals: the running speed of the belt and the instantaneous load of the materials, which are received and processed by the PLC or the system microcomputer. According to the comparison between the measured value and the set value, the corresponding conditioning signal is output, the belt speed is adjusted by the frequency converter to change the material delivery quantity, and then the material weighing and quantitative feeding control are completed accurately. In the whole process of operation, the flow can be adjusted according to the predetermined procedure and the set feeding amount to make it equal to the set value. It can transport bulk materials one after another with constant feeding rate or variable speed, and can quantitatively feed, actively measure and accumulate.

Improvement of conveyor belt hopper. It is one of the measures to improve the hopper of conveyor belt and prevent the conveyor belt from early damage. Improve the hopper at the transfer point of each belt conveyor to increase its ability to pass through foreign matters by 2.5 times. Long and large foreign matters are not easy to get stuck between the funnel wall and the conveyor belt in the transportation process, so as to reduce the probability of foreign matters tearing the conveyor belt.

The gap between the guide apron at the hopper and the conveyor belt becomes larger and larger along the running direction of the conveyor belt, so as to deal with the problem of coal and stone stuck between the conveyor belt and the apron, and clean up the conveyor belt damage caused by it. For the hopper with large drop, a buffer baffle is installed inside to prevent the material from directly impacting the conveyor belt.


   

PVC is the abbreviation of a kind of raw material, its complete scientific name is PVC, so the primary raw material of PVC conveyor belt is polyvinylidene, but if the conveyor belt is made of pure polyvinylidene, its tension is almost zero, so the conveyor belt made of products needs to add a layer of industrial polyester cloth between PVC and PVC. This kind of material has high tensile force and the thickness of the product The higher, the more layers of cloth will be used.

PVC conveyor belt has good elasticity and is not easy to deform. Choose high strength cotton, nylon, polyester canvas as the core, and use natural rubber mixture to make white or light color, which does not affect food hygiene and odor coating. PVC conveyor belt product formula design is reasonable, in line with the health indicators, moderate color, light and durable. PVC conveyor belt is suitable for food industry or food department to transport bulk, canned, packed grain or food to 400 large grain size, and the transportation capacity can be from 1 m3 / h to 6000 m3 / h.

PVC conveyor belt

Food conveyor belt is made of non-toxic raw materials, non-toxic, no odor, surface lubrication, suitable for transporting food and food raw materials and other environment.

The raw materials are PVC, polyethylene, polypropylene, acetal, PE, nylon, PA and so on. According to the details, there are corresponding special belts for food. For example, the aquatic belt requires the mesh to be permeable, anti-corrosion and easy to clean.
