For the current severe energy-saving requirements, flexible packaging enterprises should make full use of mechanized and automated production to reduce labor costs, achieve large-scale production, and achieve invisible “energy saving”.
The advent of plastic bags with mouths has changed the way traditional bags can only be sealed by film stitching, and is widely used in liquid food packaging, even ice cream. However, the way of taking the plastic bag with the mouth is mainly the manual nozzle and the first heat sealing process. The manual pipe is transferred to the plastic nozzle and the plastic bag by the heat conduction method, so that the mouth melts and the PE seal of the bag The layers are welded together to realize the molding of the mouth-filled bag, but the manual operation method is inefficient, and a manual pipe-cutting machine is operated by one person according to the twelve-hour production time, and can complete more than 10,000 bags. Production, if the order quantity is large, many or even dozens of manual tube sealing machines are needed for production, and because the heat sealing capacity of the plastic nozzle is large, the heat sealing layer of the bag will overheat when sealed. The combined area is easily crushed. Because there is no cooling and setting treatment, the appearance of the sealing part is poor, and the heat sealing strength of the bag and the straw is difficult to ensure.
At present, the automatic sealing machine for the production of plastic bags with mouth is specially used in flexible packaging enterprises. The automatic sealing machine uses the vibration automatic feeding system to arrange the straws neatly and push the straw into the bayonet through the upper mouth system. The plastic packaging bag The bag is taken out from the baghouse by the bagging system and accurately put into the straw. Finally, the pipette and the bag are heat-sealed and cooled by the heat sealing system. Such equipment has high degree of automation, requires less manpower, and has a production speed. 60/min or more, an automatic sealing machine is operated by one person according to the production time of 12 hours, and the output can reach more than 40,000 bags. Although the equipment investment is needed in the early stage, the production efficiency has been greatly improved. Reduced manpower and material resources.
