Full-automatic paper bag machine is an aspiration device for making square-bottom paper bags based on the original color or printed sheet. The process is roughly as follows: The sheet after printing (or laminating) is transported to the pull gauge part for positioning by an automatic paper feeder, and is fed into the pressure line by the rolling equipment, and then transported to the open bottom position by the transport equipment. , Carry out horizontal line pressing, bottom opening, gluing and pressing, and finally output the finished paper bag. (The mechanical speed is different due to the difference in paper quality, weight scale, printing effect, whether it is suitable for PP film, adhesive quality, paper standard, climate, and workshop environment.) The characteristic paste paper bag as a An old craftsmanship that is environmentally friendly and environmentally friendly. Now that the paper bag is planned to be printed, it has become a variety of high-end product packaging or gift bags.
        The plan for paper bags is generally very concise. As an extension of the product advertising strategy, an outstanding corporate image is the key. And now there are constantly adding ideas to use on paper bags, printing various fun pictures on paper tapes, making the day quietly more interesting. Paper bag planning parameters, shopping bag planning standard making principle The top edge of the paper bag is folded about 60mm in order to strengthen the grip of the handle. The width of the bottom edge of the paper bag is 15mm to strengthen the load-bearing capacity of the bottom of the bag (the width of the edge is reduced by 15mm). The edge of the paper bag is about 30mm. It must be on the right to be able to automatically sack the bag. The finished shopping bag should be set with folding edges such as two edges, six edges on the top, and six edges on the bottom. The production standard of shopping bags should meet the number of paper openings for economic benefits. The paper thread direction should be parallel to the "height" of the paper bag to facilitate paper folding.
        What are the precautions for the paper bag making process? A paper bag machine can debug multiple standard paper bags. One machine is multi-purpose and multi-functional. However, pay attention to the maintenance of the paper bag machine during the application process:
        Maintenance rule: It is necessary to refuel all the bushes every 2 hours within half a month after purchasing the paper bag machine, and refill all the bushes every 4 hours after half a month.
        1. After each shift, it is necessary to ensure that the stolen goods on all the rollers on the grape bag machine are cleaned up. In order to make the paper bag machine process smoothly.
        2. The chain is tight once every 15 days, with proper tightness.
        3. What to do if the paper bag machine is not completely sealed?
        Generally speaking, LDPE has moderate anti-pollution heat-sealability. EVA has excellent anti-pollution heat-sealability when VA content is large. LDPE also has excellent anti-pollution heat-sealability. Ionic resins and metallocene polymers have Has excellent anti-pollution heat-sealability.
        4. All gear top wires of the paper bag making machine are tightened every 3 days to prevent loosening.
        5. What should I do if the sealing of the paper bag machine is brittle and broken?
        Let's first analyze the elements that constitute this doubt: ① it may be too much pressure; ② the heat-sealing time is too long; ③ during the compounding and curing process, a part of the adhesive enters the film. ④ After cooling and leaving the composite packaging bag, the heat-sealing strength is increased, and it also tends to become brittle.
        6. All the fastening screws of the pressure plate are tightened once every 6 days to prevent loosening. The platen is located parallel to the large plate of the grape bag machine.
Assuming such a question arises, our solution:
        ① According to the heat-sealing characteristics of the data of the inner sealing layer, select the appropriate processing temperature, pressure and heat-sealing time;
        ② Improve the surface condition of the upper heat sealing knife to make the surface of the sealer flat. What's more, this is the question we often encounter in the usual production. Of course, we need to pay more attention to the maintenance of the equipment in order to reduce the doubts during the production process.
