With the wide application of automated production lines, professional and technical personnel, in order to meet the market demand, independent innovation, research and development of a new type of product that can be adapted to small and medium-sized enterprises to use the automatic loading machine. Mainly because the market, most of the products need to achieve, high-speed processing, high-precision feeding applications. And, in the process of use, the material surface can not leave any indentation, the production of plating material alloy, stainless steel, copper, to get the most perfect finished product. And Dongguan Tongyi Plastic Machinery Manufacturing Co., Ltd. did, but also changed the traditional feeding machine, in the mechanical operation, noisy noise; but also improve the production line qualified number of finished products, saving a lot of labour, in the automatic feeding machine equipment manufacturers to become the industry's first choice.

　　Loading machine equipment in the hydraulic cylinder according to its structural form, can be divided into piston cylinder, plunger cylinder, and swing cylinder three categories. Piston cylinder and plunger cylinder to achieve reciprocating motion, output thrust and speed. Oscillating cylinder can achieve less than the reciprocating swing, output torque and angular velocity. Hydraulic cylinder in addition to single use, but also several combinations and other institutions combined, used on special occasions, has achieved a special function. The structure of the hydraulic cylinder can be basically divided into cylinder and cylinder head, piston and piston rod, sealing device, cushioning device, as well as five parts of the exhaust device. It not only saves the time of unloading, but also can greatly improve the heavy physical labour of workers. Improve the efficiency of business. Therefore, it is an important part of modern working machine design and technical transformation of old equipment. Automatic on the unloading mechanism is a special mechanism, its structure in many forms, but mainly with the shape of the blank, and, it has a common important principle, that is, on the unloading requirements in a reliable, monkey sure, and does not cause deformation of the processed parts and damage to the processed parts under the conditions of the work cycle cycle with the work of the machine stored in a shorter period of time compatible with the work cycle. On the structure of the unloading mechanism, according to the shape of the processed parts (or blanks) can be divided into three types, each type has its own common characteristics and laws.
