Application of new material in vacuum packing machine
Application of new material in vacuum packing machine. Vacuum packing machine belongs to a kind of equipment in food machinery. It has a small proportion, strong corrosion resistance, wear resistance, friction performance, earthquake resistance and enough mechanical strength and other advantages can be compared with metal materials. So in recent years, the proportion of plastic parts in civil mechanical products is increasing, many countries have drawn up a plastic standard for industrial departments to choose. Vacuum packaging machine price is a certain difference.
Application of new material in vacuum packing machine. Japan - made simple pendulum crusher, its vibration bearing using oily synthetic resin. Some countries use capron in place of bronze sleeves.
Application of new material in vacuum packing machine. Manufacturing machine parts with plastic, not only can save metal, reduce weight but also can improve the performance of the machine, improve the reliability of the machine, extend the life of the machine, reduce the production cost of the machine. Food packaging machine is mainly used for food packaging.
Application of new material in vacuum packing machine. The wear rate of smooth manganese steel liner is two times faster than that of flat rubber liner. The rubber lining plate with steel bands only wears at the top of the steel bands, while there is no wear between the two bands. The wear amount of the rubber layer in unit time is the same between the smooth rubber lining plate and the rubber lining plate with steel bands. Therefore, the consumption per ton of material is only one third of that of smooth rubber liner. Rubber wear varies with machine size, speed, and material hardness. The experiment in Sweden proves that: after the rubber lining plate is used in the discharging end, feeding end and body of the mill, the cost of lining plate is reduced, and the installation time is 2.5~3 times faster than the manganese steel lining plate, and there is no loss to the abrasive property of the material. At the same time, can reduce power consumption and machine weight, and reduce the consumption of grinding body, extend the service life of the liner. When the mill is running, there is no noise and the working conditions are improved.
Application of new material in vacuum packing machine. When replacing steel linings with rubber linings, the cracks between the linings should not be filled with wood or steel. At the joints of the carcasses and end linings, a piece of rubber should be used to fill the gap along the circumference of the mill. Because rubber board is easy to burn, so, should be in the case of complete fire protection, the lining of the installation work.
Application of new material in vacuum packing machine. It is worth noting that, the use of rubber lining of the mill, the material's abrasiveness not only did not weaken, but also increased, this is because in the steel lining of the mill, some work is consumed by the body, and in the rubber lining of the mill, because of the role of rubber, all the work is used in the falling material contact crushing effect. In 1967, a copper mine in China imported two wet grid grinders from Sweden, both of which used rubber lining, with specifications of 4.5×4.8m gravel mill and 1.8×2.1m steel ball mill respectively.
