Spring in vending machine learning

As is known to all, with the development of economy and the people living standard rise, the vending machines are increasingly appeared in various places. The vending machine is a new retail has incomparable advantage compared with the traditional retail, can operate 24 hours a day, can be more convenient service for consumers. Operators can also periodically on the basis of the background of the vending machine replenishment, greatly reduces the labor costs. There are many kinds of the vending machine. Common is the vending machine on the market, selling drinks on commodities serpentine channel, channel in the orbit of the spring goods sold the vending machine. Here, we mainly by way of spring items to discuss some knowledge about the spring. The friend asked, spring system is not motor module and spring? What is the good discussion? Actually a lot of things on the surface looks is black and white, actually there are a lot of knowledge. Look from the material, generally divided into carbon steel, manganese steel, stainless steel. Stainless steel cost is generally not high, USES the meaning is not big. Low end of the spring is carbon steel ( Is the most common spring steel) General is manganese steel (, a little bit better High iron manganese steel) 。 Manganese steel has good corrosion resistance and rigidity, good toughness, not easy to deformation. In order to better antirust, typically involves two important surface treatment technology, electroplating and electrophoresis. Electroplating is the use of electrochemical principles in a plating on the surface corrosion of metal, the main method with nickel and chromium plating. The chrome plated appearance beautiful, good corrosion resistance, but the shortcoming is also very obvious, electroplating can seriously pollute the environment. The electrophoresis here is electrophoresis paint. Under the effect of external DC power supply, the colloidal particles in the dispersion medium directional movement to the cathode and anode. Using this principle to painting, has the advantages of low pollution, saving energy, saving resources. The vending machine spring goods channels in appearance is also very good. Electroplating the surface of the spring is bright metal color, like a mirror, electrophoresis spring is black, the surface has a very uniform paint film. Environmental protection is more valued over the past two years, so the vending machine spring plating less and less, are generally electrophoresis paint. In brief, on the premise of not affect use, electrophoresis process cheaper, more energy conservation and environmental protection.
