The characteristics of mechanical and electrical integration of packaging machinery

Packaging is a necessary condition for products to enter the circulation field, and the main means of achieving packaging is the use of packaging machinery. With the development of the times and the advancement of technology, packaging machinery is playing an increasingly important role in the circulation field. Traditional packaging machinery mostly uses mechanical control, such as cam distribution shaft type, and later appeared electronic control, photoelectric control, pneumatic control and other control forms. However, with the increasing productivity and the random variation of packaging parameters, these control systems have become more and more difficult to meet the development of the new situation. At this time, a new technology: mechatronics technology came into being, it completely changed the face of packaging machinery, so that it appeared in the world in a new attitude.

First, the characteristics of mechatronics technology:

1. In the current era of rapid changes in science and technology, the emergence of various new technologies, new processes, new materials, and new equipment is no longer a mere development of a certain discipline, but a related discipline and a variety of advanced technologies. Interpenetrating and complementary results. Mechatronics technology is one such new technology. It is a comprehensive technology based on information theory, cybernetics and system theory. The essence is to use the principle of process control from the system point of view, organically combine machinery, electronics and information, testing and other related technologies to achieve overall improvement. Specifically, it introduces microcomputer technology into packaging machinery.

2. Mechatronics has fundamentally changed the face of packaging machinery. In this packaging machine, the microcomputer acts as its brain, replacing the conventional control system. The mechanical structure is its main body and torso. Various instruments, instruments and sensors are their senses. They feel the changes of various packaging parameters and feed them back into the brain (microcomputer). The various actuators are its hands and feet. The actions necessary for the packaging operation.

3. A complete mechatronic system, generally including microcomputers, sensors, power sources, transmission systems, actuators, etc. It eliminates the cumbersome and unreasonable parts of conventional packaging machinery, and integrates advanced technologies from various disciplines such as mechanics, microcomputers, microelectronics, and sensors, bringing profound advances in packaging machinery in design, manufacturing, and control. The change has fundamentally changed the face of packaging machinery.

Second, the advantages of mechatronics on packaging machinery:

A new technology, once turned into productivity, often plays a huge role. If the error of photoelectric positioning is much smaller than that of mechanical positioning, the effect of microwave drying is much better than that of electric heating and drying. The time for mechatronics technology used in packaging machinery is not long, but the effect is obvious and the effect is huge. The advantages of mechatronics on packaging machinery:

1. Make the mechanical structure much simpler.

The control system is the starting organ of the machine. The traditional packaging machinery control system mostly uses relays and contactor control circuits. The complexity is increased with the increase of the actuators and the increase of the adjustment parts, which makes the machines more and more complicated. Inconvenience to manufacturing, adjustment, use and maintenance. Mechatronics can replace the bulky electrical control cabinets and drive units with microcomputers, sensing technology, and new transmission technologies, resulting in a drastic reduction in the number of components, a greatly simplified structure, and a reduction in size.

2. Product quality is improved.

There is a huge storage system in the microcomputer. People can pre-store the parameters and related data that affect the operation of the packaging machine into the microcomputer, which can automatically track the production process. When a parameter or several parameters change, the change is instantaneously fed back to the microcomputer, and the microcomputer recognizes, judges and corrects the changed parameters in time, so that the packaging machine can maintain the working state at any time. However, when the traditional packaging machine changes its process parameters, its adjustment is based on experience. It is difficult to find the good parameters of Zui. If several process parameters change at the same time, it is even more inappropriate. Such as the common plastic bag sealing machine of Zui, the sealing quality is related to the packaging material, heat sealing temperature and running speed. If the material changes (material, thickness), then the temperature and speed will change, but the change is difficult to grasp. If the microcomputer control is used, the sealing temperature and speed of various packaging materials are matched into the microcomputer memory, and then the necessary sensors are combined to form an automatic tracking system, so that no matter which process parameters are changed, the Zui can be guaranteed. Good sealing quality.

The more parameters change, the more adjustments are made, and the superiority of mechatronics is greater, which is incomparable with the general control method.

3. Increased functionality and improved reliability.

In addition to maintaining the functionality of the original packaging machine, mechatronics can also be given many other functions. Such as liquid beverage soft packaging machine, it can have the functions of box making, sterilization, filling, sealing, etc. under the cooperation of pneumatic, electrical and mechanical, but if the microcomputer is introduced into the control system, it can also store such as production rate, Data such as the number of products, fault phenomena, and causes of failures can be processed according to the actual situation, and the results can be printed out or displayed on the screen, which greatly facilitates the operation.

Mechatronics will also give the packaging machine automatic monitoring, dynamic detection, alarm and other functions, as well as safety interlock control, overload and out of control protection, so that the reliability of the packaging machine is greatly improved.

4. Easy operation and improved efficiency.

The packaging machine designed with mechatronics technology has a highly concentrated display of digital display and various information, greatly reducing the operation buttons and handles, and has program control and other functions. The operating procedures are greatly reduced and the operator is also easy to train.

Conventional packaging machines are mostly driven by asynchronous motors. In fact, they are mostly in a light load working state, and energy is wasted. Mechatronics technology replaces the asynchronous motor with a variable frequency motor. The microcomputer automatically finds the working point of the Zui, and randomly adjusts the output power of the variable frequency motor, which generally saves 40% of energy. In addition, its reliability is improved, product quality is guaranteed, and benefits are improved.

Mechatronics is the development direction of packaging machinery. Although its application time is not long, it has shown great superiority. With the popularization and promotion of mechatronics in packaging machinery, it will definitely develop the packaging industry in China. To a positive role.
