Packaging machinery includes a wide variety of products, such as installation packaging (bag), packing, packaging, sealing, strapping and other machinery. Although the packaging technology, packaging materials and packaging materials of these packaging machines are different, they all have a common structure and a part of a special structure. The general structure of all kinds of packaging machinery is called the basic structure of packaging machinery. The basic structure of packaging machinery is mainly composed of power unit, transmission mechanism, feeding mechanism, metering device, control system, body conveying device and seven parts.
1、 The basic structure of packaging machinery power unit.
The power unit is the driving force behind the mechanical movement. The kinetic energy generated by the motor, hydraulic pump and air compressor drives the operation of the whole packaging machinery. Used in the most common motors. Each machine can be an electric motor, which drives the moving parts through the transmission mechanism. In order to promote the adjustment and drive of various moving parts, the high modernization of packaging machinery tends to use several small power motors as the power source of a single component. Packaging machines actually require less power, usually between 1 and 3KW. Most of the power consumed in mechanical transmission, therefore, friction loss should be adopted in design rather than rolling friction loss of large mechanical linkage mechanism.
In modern packaging bags, the first-class automatic bag packing machine is the mainstream of development, because such a packing machine can simplify the packaging production process, save labor and improve the output of working cattle, reduce production costs and wide adaptability, so flat bags, flat bags and other forms of round bags, etc.
2、 Basic structure of packaging machinery - measuring device
Measurement is an important step in quantitative packaging. With the difference of body goods, packaging and packaging specifications are also different; even for the same commodity, due to the need to sell a variety of packaging specifications to meet the different requirements of consumers. This leads to the complexity of measurement. When the quantitative special packaging metering device is a quantitative metering device, the quantitative value is required. Due to the different types, performance, value and packaging methods of the packaged goods, it is impossible to carry out the measurement work, and the measuring device will be the same as other items that do not need to be measured according to the type, behavior, numerical value and measurement accuracy requirements.
3、 Basic structure of packaging machinery control system
Many packaging machinery control systems include: electromechanical control, photoelectric control and electronic control. Their main functions are used for weighing, counting, positioning, measuring, feeding, blanking, safety and protection. All aspects of the function, there are certain devices.
