Although these packaging machines differ in the packaging process, packaging materials, and packaging materials, they all have a part of a common structure and a part of a special structure. The common structure of various packaging machines is called the basic structure of the packaging machine. The basic structure of the packaging machinery consists of seven parts: power components, transmission mechanisms, feed mechanisms, metering devices, control systems, conveyors, and airframes.
First, the basic structure of packaging machinery - power components.
The power unit is the prime mover of mechanical movement, and the kinetic energy generated by the motor, hydraulic pump, and air compressor promotes the operation of the entire packaging machine. It is most common to use electric motors. Each machine can use an electric motor to drive each moving part through the transmission mechanism. In order to facilitate the adjustment and driving of various moving parts, packaging machines with a high degree of modernity often use several small-power motors as power sources for individual parts. The actual power required by the packaging machinery is small, generally between 1-3kw. Most of the power is consumed in the mechanical transmission. Therefore, in the design, the friction mechanism with a small friction loss should be used instead of the link mechanism with large friction loss.
In the production of modern bagged packaging, the former-class automatic bag-packing machines are the mainstream of development, because these packaging machines have simplified production processes for packaging, saving labor, improving the productivity of working cattle, reducing production costs, and adaptability. Wide, can apply to flat bags, cylindrical bags and other forms of bag and other advantages.
Second, the basic structure of packaging machinery - measuring devices
Metering is an important process when quantitatively packaging items. With different types of goods, packaging methods, packaging specifications are also different; even if the same kind of goods, due to the need to sell a variety of specifications of the packaging to meet the requirements of different consumers. This has complicated the measurement work. Quantitative packaging using a special device metering device, that is, the required quantitative value. Due to the variety of items being packaged, performance and value are different, and packaging methods are also different, so the measurement work can not be divided, and the measurement device will not be different according to the variety, performance, value and measurement accuracy requirements of the measured items. the same.
Third, the basic structure of packaging machinery - control system
There are many control systems for packaging machinery, including: electromechanical control, photoelectric control, and electronic control. Their main function is for weighing, counting, positioning, measuring, feeding, cutting, safety and protection. All aspects of the function, there are certain devices.
