The difference between cylinder filling and sealing machine and mechanical linkage filling and sealing machine

In the market now, there are two main types of filling and sealing machine, cylinder action filling and sealing machine and mechanical linkage filling and sealing machine, then, cylinder filling and sealing machine and mechanical linkage filling and sealing machine what is the difference? Here, let's take a look together.

A. Comparison of cam action and cylinder action

1, the structure of the movement characteristics: wheel organization compact structure, high reliability, to complete high-speed automation. In automatic machinery, although also able to use pneumatic equipment, but the pneumatic action ends with a large impact, when the speed is changed, the throttle valve needs to be adjusted, when the production speed progresses more, the cylinder equipment is obviously unable to help. And with cam organization can obtain smooth movement, when the speed change can also maintain synchronization. The air pressure is easily affected by the pressure system, when the same air source of other cylinders in a hurry, the air pressure will drop, and the movement of the cylinder will change, while the cam has been in a stable condition.

2、Timing of the movement: The action of the cylinder is one after another, and it is necessary that one action is completed before the next action can be carried out. The cam displacement (point of view) and the moment are determined, the action is able to superimpose, and the next action can be started when an action is not finished, so the cycle time can be shortened.

3、Failure rate: A well planned cam organization can be used for the life of the equipment, but the cylinder cannot meet this requirement.

4, action changeability: When the sequence and time of action need to be changed, obviously the cam organization can not help. Once the cam organization planning to use, basically can not be changed (except for some planning into adjustable point of view of the cam strong can adjust a point of view), is rigid. This is not the case with pneumatic. It can be adjusted by PLC and is flexible.

5, there is no doubt that the energy consumption of the cam is less than that of the cylinder equipment, in terms of energy conversion, the energy of the cylinder is converted from the air compressor, there is a conversion loss and serious leakage of the pipeline.

Second, on the cam action and servo control system comparison

Undoubtedly, servo control because there is a strong adaptability and flexibility in today's occupy an increasingly important position.

Servo manipulation is able to obtain good dynamic characteristics of motion by mapping the motion curve, and many excellent motion curves are developed for servo needs.

Compared with cam organization, the main difference is the variability and invariance. As mentioned earlier, servo has strong adaptability and variability, while the action stroke, synchronization and motion characteristics of cam organization are unchanged, and its motion condition will not change no matter how much the load has changed. The servo organization is digitally controlled by the servo motor to complete the motion control, and the cam organization with the same motion curve and the servo organization produce different motion power effects. It is a pity to say that the cam organization is superior in this aspect.

So, whether to choose the cylinder filling and sealing machine or mechanical linkage of the filling and sealing machine, we can refer to the above analysis!
