What are the matters needing attention in the bag making process of the paper bag machine? One machine can debug multiple standard paper bags, one machine is multi-purpose and multi-functional, but the maintenance of the paper bag machine should be paid attention to during the application process:
Maintenance rule: All shaft sleeves need to be refueled every 2 hours within half a month after purchasing the paper bag machine, and all shaft sleeves need to be refueled 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 smoothly.　　　　　
2. The chain should be tightened once every 15 days with proper tightness.
3. What should I 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 resin and metallocene polymer Has excellent anti-pollution heat-sealability.
4. All gear top threads of the paper bag 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 brittle?
Let us first analyze the factors that constitute this question: ①It may be excessive pressure; ②The heat sealing time is too long; ③In the process of compounding and curing, part of the adhesive enters the film. ④After the composite packaging bag is cooled and placed, the heat seal strength increases, and it also tends to become brittle.
6. Tighten all clamp screws once every 6 days to prevent loosening. The pressing plate is located at the parallel big plate of the grape bag machine.
Assuming such a question arises, our solution:
①According to the heat sealing characteristics of the inner sealing layer materials, select the appropriate processing temperature, pressure and heat sealing time;
②Improve the surface condition of the upper heat sealing knife to make the surface of the sealer flat.
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 the usual way to reduce the doubts that appear in the production process.

Ban on upper and lower films
The ban on upper and lower sheets refers to the question that the front and back sides are not aligned when making the bag
1. Factors
The thickness of the composite film is uneven, with lotus leaf edges.
The tension of the double lifting roller is too small.
Some rollers do not rotate smoothly.
2. Solution
Check and adjust the relevant guide rollers (such as compensation rollers, offset rollers, etc.).
Adjust the tension of the double lifting roller.
The cover has spots and bubbles
Varieties and bubbles on the cover mean that the sealing surface is not flat
1. Factors
The heat-sealing knife or heat-sealing silicone pad is uneven.
When heat-sealing is performed on a material structure rich in hygroscopicity such as nylon film, air bubbles will occur when the hygroscopic film absorbs moisture.
Lack of heat sealing pressure.
Use one-component adhesives, such as neoprene adhesives, when heat sealing the bag. The hot cover can easily show uneven pits.
2. Solution
Replace the binder.
Check or adjust the heat sealing knife and heat sealing silicone pad.
Keep the raw materials and semi-finished products properly to prevent them from absorbing moisture.
Scale error
1. Factors
Operating factors, such as improper tension control, lack of pressure setting of the pressure cylinder of the film rubber roller, etc. Electric eye tracking is forbidden. The influence of plastic composite film bag processing speed. The bag length fixed-length system of the bag-making mechanism is too bad.
2. Solution
Decrease the bag making speed, and adjust the bag making speed slowly.
The pre-adjusted film feeding length (when adjusting the white bag) and the actual bag size should be as accurate as possible.
Check whether the compression degree of the compressed film ruler and the friction coefficient of the composite film are appropriate.
Adjust the pressure of the film rubber roller, the cylinder pressure and the tension of each part.
Check whether there is a cursor printing question or distance question, and adjust it.
Adjust the fixed-length system.

China is a big country in the production and consumption of international packaging. The proportion of plastic packaging and paper bag machine packaging in the total output value of the packaging industry has exceeded 30%. It has become a new force in the packaging industry, in food, beverages, daily necessities, and industrial and agricultural production. Plays an irreplaceable effect. In recent years, packaging products and packaging materials for the plastic packaging and paper bag machine packaging professions have increased steadily, and new packaging materials, new skills, new skills, and new products have continued to emerge.

The gluing position of the paper bag machine is on the spine and the side, and the hot melt adhesive used is also different. For example, the performance of the two is also different, and the hot melt temperature is different. It is necessary to grasp the proper quality of gluing and gluing Important, if the temperature of the melt is too high, the melt will be too thin and the viscosity will be insufficient. If the temperature of the melt is too high, the glue will be too thick to penetrate and flow, and some will appear as small granular blocks attached to the ridge or side. The cover will be wrinkled and hollow on the surface. It is worth mentioning that at present, the performance of hot melt produced by different manufacturers is not the same (we have this experience from actual use). Take the hot melt temperature of the hot melt adhesive used in our factory as an example, there are The side glue temperature is 120℃, the spine glue hot melt temperature is 135℃, and some side glue hot melt temperature is 180℃, and the spine glue heat is 200℃. Therefore, it is necessary to master the appropriate process parameters according to the properties of the material in use to ensure the quality of the glue. Normally, after gluing, the width of the side glue covering is 4mm~5mm. The spine glue can penetrate and fill the milling groove. If the glue is uneven, the glue is too thin, and the pallet of the cover paper bag machine is not replaced as required (or the height is adjusted appropriately), the book after the plastic bag is prone to empty ridges and wrinkled backs. This is something that must be controlled and inspected during the plastic packaging process.
The finishing work before the glue bag of the paper bag machine is a process that cannot be ignored in the whole process of wireless glue binding. If the paper bag machine enters the plastic bag after the finishing process is not completed, then the plastic bag will have many kinds of poor quality problems such as peeling, loose pages, empty ridges, and wrinkled ridges. Sorting is to bundle the semi-finished book stickers, put a certain number of book stickers on the strapping machine, fasten the two ends with plates, start the strapping machine, compact the loose book stickers and then tie them with rope. In order to make the back stiff and firm after compaction, after compacting and binding, paint the back of the book with polyethylene glue once again. After the applied polyvinyl alcohol glue dries, loosen the rope, and then Separate each book into a plastic bag.
In perfect binding, milling and finishing is a key process. The milling back should be determined according to the thickness of the paper sheet and the number of folded layers. Generally, it should be milled away from 1.4mm to 3mm, and the roughening depth is required to be 0.8mm to 1.5mm. If the depth of milling and roughing is not enough, it will inevitably affect the penetration of the glue, resulting in quality defects of peeling and loose pages. In the paper bag machine, in the finishing process before the plastic bag, if the book stickers are not smashed, bundled unevenly, and not compacted, they are transferred to the milling back. Then the semi-finished product with this quality defect must be the book back after being clamped by the book clip in the plastic bag machine. Unevenness, the milling cutter cannot mill, and the book back roughening depth is not enough. The above-mentioned quality defects of glue impermeability, peeling, and loose pages must exist. Therefore, if peeling and loose pages are found in the quality inspection after the plastic bag, while checking whether the milling and roughing depth is appropriate, check the semi-finished product processing of the collating, binding, and compacting processes of the plastic bag. Quality situation.
