Second, and other basic trigonometric function algorithm
abs () function, such as: the absolute value of abs (-1) = 1
acos () function, such as: the arccosine acos (0.5) = 60
ainv () function, such as: the involute ainv 0.0149043838673 (= 20)
asin () : the arcsine function, such as library functions like sin (30) = 0.5
atan () function, such as: anti-tangent atan (1) = 45
ceil (less than) : please give the smallest integer constant, such as: the ceil (1.1) = 2, ceil (1.9) = 2
cos () function, such as: the cosine cos (60) = 0.5
ee: 2.7182818284590452354 = constant
floor () : please don't give the biggest integer greater destiny, such as: the floor (1.1) = 1, floor (1.9) = 1
inv () function, such as: the involute inv (20) = 0.0149043838673
ln () : for the logarithm of natural e, such as: ln (ee) = 1
log (10) : for the bottom of the logarithm, such as: log (10) = 1
PI: 3.14159265358979323846 = constant
In the triangle function to PI needing attention, such as: cos (PI / 3), we want it should equal cos60 = 0.5, but not in the calculation of not ask, cos (PI / 3) = 0.9998329794591 trigonometric function, in the PI PI doesn't mean 180 degrees, not only in the calculation of pure representatives cannot inside this constant PI, If need to use, PI representative Tod (PI) converting it into Angle 180
library functions like sin () function, such as: the sinusoidal library functions like sin (30) = 0.5
tan () function, such as: the tangent: tan (45) = 1
Tod () : radian, such as: converting Angle Tod (PI) = 1.8
toint () : rounding integer, such as: toint (1.1) = 1, toint (1.9) = 2
torad () : converting Angle, such as: torad radian (180) = 3.14159265358979

The rapid development of China's economy has resulted in the unprecedented abundance of consumer goods which improve the quality of life. On their way to the buyer, how the products are packaged has taken on increased importance. Advancement in product packaging technology has reached a very high degree of efficiency and sophistication, with packaging machinery and equipment playing a critical role.
Today, packaging machinery figures prominently all industries. From small, semi-automatic machines to large-scale packaging assembly lines, they are an integral part of the production process. They have become an important part in China's economic development.
The automatic packing equipment is comprised of a control system and an operating system. Its main role is to transport the EPS packaging bag onto the conveyor, flips it down then flattens it, and move to the next stage of processing of stacking and shipping.
This article presents the key elements of the EPS package auto-turning device and its design principles, and explains in detail the main functions of its conveyor and control systems.

Abstract
With the development of China's economy, the domestic life rich unprecedented development of consumer goods. In these consumer goods to the customers in the process of the hand, packaging has more and more important role. The development of science and technology make product packaging quality, efficiency, reached a high degree, including packaging machinery played a crucial role. Now, packaging machinery products have been in every industry can find it figure, small to a semi-automatic packer, packaging production line, the production process is the indispensable part in, at the same time also on our country's economic development plays a very important role. This paper mainly introduces a kind of online EPS bags automatic equipment down the basic principles, structural design, and the conveying system and the main functions of the control system in detail. The automatic packaging equipment is mainly composed of control system, the work of the system. The main function of the conveyor belt conveyor is EPS bags cast down, and make its place, then enter into a plastic stage, convenient DuiMa and transportation.
Key words: packaging machinery efficiency quality
Summary
With China's economic development, the development of the domestic consumer goods is an unprecedented wealth. These consumer goods reach the hands of the user process, packaging occupies an increasingly important position. The development of science and technology makes the quality of the product packaging, the efficiency has reached a very high degree of packaging machinery has played a crucial role. Today, packaging machinery products can be found in the various industries in its presence, as small as a semi-automatic balers, large packing line, an indispensable part of all production sectors, but also on China's economic development has played a very important role. This paper introduces the basic principles of structural design, an on-line EPS bags automatically tear down the equipment and its main function of conveying systems and control systems are described in detail. The automatic packaging equipment control systems, systems of work. Its main role is to tear down the transport conveyor EPS bags, to make it flat, and then into the next shaping stage to facilitate stacking and transport.
