Packaging is a necessary condition for products to enter the field of circulation, and the main means to achieve packaging is to use packaging machinery. With the development of the times and technological progress, packaging equipment is playing an increasingly important role in the packaging field. Its main functions are as follows:
        (1) Can greatly improve labor productivity
        Mechanical packaging is much faster than manual packaging. For example, candy packaging, manual packaging of sugar can only pack more than a dozen pieces per minute, while candy packaging machines can reach hundreds or even thousands of pieces per minute, improving efficiency dozens of times.
        (2) Can effectively ensure the quality of packaging
        According to the requirements of packaging items, mechanical packaging can obtain packaging with consistent specifications according to the required form and size, but manual packaging cannot be guaranteed. This is especially important for export commodities. Only mechanical packaging can achieve standardization and standardization of packaging and meet the requirements of collective packaging.
        (3) Can achieve operations that cannot be achieved by manual packaging
        Some packaging operations, such as vacuum packaging, inflatable packaging, skin-packing, isobaric filling, etc., cannot be achieved by manual packaging and can only be implemented.
        (4) Can reduce labor intensity and improve working conditions
        Manual packaging is very labor-intensive. For example, manual packaging of large and heavy products is physically demanding and unsafe. For light and small products, due to the high frequency and monotonous action, workers are prone to occupational diseases.
        (5) Labor protection for workers
        For some products that seriously affect the health of the body, such as serious dust, toxic products, irritating and radioactive products, manual packaging will inevitably endanger health, while mechanical packaging can be avoided, and it can effectively protect the environment from pollution.
        (6) can reduce packaging costs and save storage and transportation costs
        For loose products, such as cotton, tobacco, silk, linen, etc., using a compression packaging machine to compress and pack can greatly reduce the volume, thereby reducing packaging costs. At the same time, the volume is greatly reduced, saving storage capacity, reducing storage costs, and facilitating transportation.
        (7) can reliably guarantee product hygiene
        Certain products, such as food and pharmaceutical packaging, are not allowed to be packaged by hand according to the Sanitation Law, because they will contaminate the product, and mechanical packaging prevents direct human contact with food and drugs, ensuring sanitary quality.
        (8) Can promote the development of related industries
        Packaging machinery is a comprehensive science. It involves a variety of disciplines such as materials, technology, equipment, electronics, electrical appliances, and automatic control. It requires synchronous and coordinated development of related disciplines. Problems in any discipline will affect the overall packaging machinery. performance.
        The production process of paper bags includes several steps such as feeding, production, and finishing, as well as related pre and post processes, such as cleaning, stacking, and disassembly. In addition, packaging also includes metering or stamping on packages. The use of mechanical packaging products can increase productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of cleanliness and hygiene.
        1. What are the factors that cause the shrinking machine to heat up slowly or fail to rise to a higher temperature (above 160 degrees Celsius)?
        The circuit of the heater is that the main power line passes through a magnetic switch and then to the electric heating tube, so you should first check whether the contacts of the magnetic switch are normal. If the line does not pass through a phase in between, the above phenomenon will appear. If the magnetic switch is normal, check the meter again to see if the phase and the ohmic value of the machine are the same. If normal, it should be a short circuit. If all phases are connected but the line or heating pipe is still abnormal, the heater needs to be replaced.
        2. How to adjust the film when the equipment is easy to shift during normal operation?
        In the case of film deviation in the equipment, after adjusting the film roll orientation and tension balance bar are invalid, you can adjust the viewpoint of the upper triangle plate to deal with this problem. If the upper film material violates the clamping chain, the upper triangle plate can be adjusted clockwise; if the base film material violates the clamping chain, the upper triangle plate can be adjusted counterclockwise.

        3. When packing 6-pack bundles, the electric eye cannot detect the package. When the machine is operating, the package is simply cut. How should it be adjusted?
