In recent years, to speed up the structural adjustment of the food industry, promote industrial transformation and upgrading, and build a modern food industry system with Chinese characteristics, the industry concentration of the domestic food industry has greatly increased, the enterprise scale expansion, production capacity enhancement, the production efficiency of the equipment, the degree of automation also has further requirements. Therefore, automated food conveying equipment ushered in greater market opportunities.
According to the transport system of different production industries, assembly line because of its large conveying capacity, long delivery distance, in the production operation can be ** rate of continuous repeated operation, and has a strong rhythm. Input in the assembly line production operations are: food plate chain conveyor, food belt conveyor, food mesh belt conveyor, food roller conveyor, food screw conveyor and food bucket elevator conveyor.
Food belt conveyor plastic bearing housing development status quo
The traditional plastic bearing housing of food belt conveyor machinery is based on a single engineering plastic material. In recent years, to adapt to a wider range of application needs, especially food, medicine, beverage and other industries on the production environment, equipment reliability, equipment efficiency requirements continue to improve, a variety of composite materials plastic bearing housing plays an increasingly important role.
Plastic bearing housing through the addition of composite fibre filler, can achieve high compression resistance, heat resistance and creep resistance, composite fibre itself has good friction properties; adding solid grease, the selected synthetic materials and composite fibres combined to help reduce friction. Plastic bearing housings have excellent friction properties, but also have high precision, low thermal expansion, low water absorption, high compressive stress resistance, creep resistance and other characteristics.
Plastic bearing housing production material, as a new type of polymer material, friction coefficient is small, from the wear-resistant loss of nature, plastic bearing housing production material than ordinary carbon steel and other materials such as bearing housing is more wear-resistant, and also has the characteristics of self-lubricating. The conditions of self-lubrication is the cohesion between molecules to be small, the molecular structure of the atoms are symmetrically arranged, in addition to lubrication performance and lubrication conditions. Plastic bearing housing surface strength is relatively high and very smooth, basically does not appear tension, has good self-lubricating properties and low coefficient of friction, in keeping with the traditional advantages of plastic bearing housing on the basis of the production operation can be used in the more precise or for high speed operation of the conveyor operation. Plastic bearing housing can contain alkaline materials in the operating environment, play a better role, but is not suitable for corrosive environments containing acidic substances running operations. Plastic bearing housings have high rigidity and hardness, and even in a low-temperature operating environment, the strength of impact resistance is relatively high.
Plastic bearing housing is an indispensable and important component of food belt conveying machinery and equipment transmission, in the production of conveying operations can better improve the transmission efficiency of the conveying equipment, thus playing a role in reducing energy consumption. China’s bearing housing in the process of development of modern science and technology, in order to make the bearing housing better to improve the bearing capacity, in the performance of the bearing housing as well as the material, have carried out a more excellent innovation, and the use of engineering plastics to produce the bearing housing. After testing, the plastic bearing housing is stronger than the rigidity and hardness of ordinary steel bearings, so it is used in different food belt conveyor production and conveying industry.
The vision of star-shaped wheel for food belt conveyor parts
The symmetry of the gearing structure of the star-shaped wheel makes the star-shaped wheel with several evenly distributed planetary transmission running track, and under the action of the food belt conveyor transmission, so that the central wheel and the rotating arm bearing force can balance each other, thus helping to achieve the role of improving transmission efficiency. Only need to properly select the type of planetary transmission and gearing programme, you can use a few dozens of gears and get a large transmission ratio.
As the star wheel adopts several identical planetary wheels, evenly distributed around the central wheel, so that the inertia force of the planetary wheel and the rotating arm can be balanced each other. At the same time, it also makes the number of teeth involved in meshing increase, so the planetary gear transmission movement is smooth, strong resistance to shock and vibration, work more reliable, so the star wheel in the production of conveying operations, can be better to carry out a relatively smooth conveyor; at the same time, the star wheel’s resistance to shock and vibration of the ability to be relatively strong.
Food belt conveyor star wheel transmission mechanism in the gear, widely used carburisation and nitriding and other chemical heat treatment. Gear manufacturing accuracy are generally more than six levels. Obviously, the use of hardened tooth surface, high precision is conducive to further improve the load carrying capacity, so that the gear size becomes smaller.
Hard tooth surface, high precision. The materials used in the manufacture of star wheels include fine grain steel with high alloy content and also good hardenability. As the quenching temperature decreases, the hardness of the tooth surface does not change much, but the hardness of the heart decreases more significantly. The increase of carbon and nitrogen compounds of the star wheel can effectively improve the wear resistance and contact fatigue strength, and the appropriate amount of residual austenite helps to improve the contact stress state of the surface, after carbon and nitrogen co-infiltration treatment, in the wear resistance, contact fatigue strength and deformation of the performance of the amount of deformation, can be relatively good to use.
Star-shaped wheel transmission mechanism in the high-speed transmission, transmission power is also relatively large, but also can be used in the low-speed, heavy-duty food belt conveyor transmission, can be better to pass large torque, large size of the conveyor, so the star-shaped wheel is widely used in the production of food industry enterprises in the field of conveying operations, but also can be better applied in the speed reducer, incremental speed incremental speed and speed changer and other various mechanical transmission system.
Food conveying equipment demand is getting stronger and stronger
China’s deep processing industry of agricultural products on the conveyor belt is not only thirsty for the number of stainless steel mesh belt and more importantly, the level of science and technology and performance, quality. This points out a clear way for the development of China’s conveyor mesh belt industry.
