Understand the development process of packaging machines for many years, it is not difficult to find that there are some significant shortcomings in China's packaging machine industry, which is roughly summarized as follows: low-level products are repeatedly produced, and the skills of these devices are small and low-cost. And the start-up is fast, so many companies will select these devices as "getting started" products, in order to accumulate funds and renew their plans, but this will inevitably repeat the products, which will also cause them to be bought, which will naturally affect them. The update of the equipment will make it difficult to improve the production level. On the one hand, the packaging machine started late in this respect, and has not yet figured out the rules of the market; on the other hand, it is weak in science and technology and lack of high-tech talent resources.
        The common question is that the production company of the packaging machine will not pay attention to the quality of the goods. The first performance is in two directions: one is the processing parts themselves, some are not high precision, some are poor raw materials, some are not heat treated, the forging The lack of forging, the equipment presented a lot of questions, which is the primary reason behind the company's packaging machine behind, packaging goods error, high scrap rate.
        The protection of goods has not received attention. The company adopts fewer methods for the safety of packaging machines. For example, the protective cover and protective door are mostly not installed. Some are installed, but they cannot be safely interlocked, and only have protection against depression. Especially with regard to heavy bag packaging, the labor intensity of workers is high, and safety is even more important, so it must lead to satisfaction.

For the problems in the use of paper bag machines, many novice friends will be at a loss, today Xiaobian here to introduce to you the problem of the temperature instability of the paper bag machine, the reasons for this situation are also introduced to you a bit.
The reasons for temperature instability are as follows:
1. The walking of other wires interferes with the temperature or is caused by a short circuit.
2. There is a problem with the motherboard inside the computer. The accurate judgment of this problem requires certain professional skills.
3. Check if the thermocouple is loose or falling off.
4. Does the set temperature correspond to the set cutter?
5. Whether the sealing knife is installed tightly.
6. Whether the wire is burnt and loose.
7. Is the switch inside the cabinet open?
It should be noted that when the temperature is unstable, the unstable seal number can be pressed at the channel number, so it should be reset once according to the original number to ensure that it can work normally.
After solving the problem of unstable temperature, how to solve the problem when the paper bag machine has no color-coded signal?
No color standard signal reason:
1. Adjust the sensitivity of the photoelectric.
2. The pressure of the front drag rubber roller should not be too small, generally not less than 0.3.
3. Too much dust and stains on the photo head should be cleaned up.
4. Heat the knife and cool it to a low drop (adjust the knife distance).
5. Set the bag length to the actual bag length does not match (modify the bag length parameter).
6. The color code area is too small (not less than 1mm, not more than 3mm).
7. The polarity setting is incorrect.

        To see that there are two main types of paper-feeding machines at the bottom of the domestic market: this is also to help us to achieve a roll-type portable paper bag machine; It is a single-sheet portable paper bag machine. The natural thing is to have automatic feeding of both devices, and we have to see that after the automatic gluing, the automatic paste. This is to make the product beautiful; second, the finished paper bag needs to manually paste a bottom paper on the bottom of the bag. At this time, it is necessary to enhance the strength of the bottom of the paper bag. We need to know the current technology and be able to solve the problem of manual paper sticking on traditional paper bag machines.
        I can see that after the traditional square bottom paper bag machine sticks to the bottom, we have to be able to manually paste a layer of bottom paper from the inside of the bottom of the paper bag, because we have to consider the speed of bag making in this way. Slow, and in the poor quality of the bag. The National Research Institute's bottom portable paper bag machine can automatically paste the bottom and automatically paste the bottom paper, reflecting the technological innovation. We have to see that in the product, there must always be an indentation on the front side of the paper bag that is made, which affects the appearance of the paper bag. The machine adopts innovative design to solve the problem of indentation on the side of the paper bag. The quality of the produced products is good and the appearance is exquisite.

        Fully automatic paper bag machine for paper: kraft paper, coated paper, white paper, white cardboard, etc. (including laminated paper)
        The automatic paper bag machine is ideal for making square bottom paper bags with original color or printed paper. The process flow is roughly as follows: the flat sheet paper after printing (or film coating) is conveyed to the pull gauge part by the automatic paper feeder for positioning, and the rolling device is used to enter the pressing line, and then sent to the bottom position through the conveying device. Press the transverse line, open the bottom, glue, press and finally output the finished paper bag.
        The reel bottom paper bag machine can complete the top color, the printed roll paper, the upper side glue, the tube, the cut, the bottom indentation, the glue, the bottom of the bag, and the bag. It is the production of food bags, garment bags, shopping bags, etc. Ideal equipment.
        The fully automatic flat-bottomed square-bottomed paper bag machine is made of a single sheet of paper, a reel-type head card and a paper rope. The handle is manufactured in one time, the handle is folded, the mouth is folded, the tube is formed, the accordion is sealed, the back cover is compacted. Molding or sticking card, folding the mouth, forming a tube, forming an organ, punching the eye, sealing the bottom, compacting the two perfect processes, one machine and two use, value for money. It is especially suitable for the production of outer handbags for clothing, footwear, sports brands or luxury brands. Realize the full-automatic production and package it directly to customers.

        In order to better develop the paper bag machine industry in China, China has proposed low quantitative problems in news paper, letterpress paper and offset printing paper, paper bag machine, etc., and began to solve it. In many applications of paper, packaging paper and paperboard should achieve high quality and light weight and brand diversification. In particular, the largest amount of corrugated base paper and kraft paper, according to the domestic demand for high-end packaging, to produce a more efficient and safe paper bag machine.
        The use of new technology can make our paper bag machine products have a better development prospect, can fully enrich the resources, reduce the pollution to the environment, in order to better play the characteristics of the current machine, improve the paper bag making process In the process of designing machines that are more in line with customer needs.
         From the perspective of product structure, the application of packaging machinery and equipment in life is also quite extensive. There are only 1,300 kinds of packaging machinery in China, the number of configurations is small, the lack of high precision and large-scale chemical products can not meet the market demand: the product quality gap is reflected in the product performance. Low, poor stability and reliability, unsightly appearance, rough surface treatment, poor quality of many components, short life and low reliability, affecting the quality of the overall product; from the perspective of the company, the domestic packaging machinery industry lacks leading enterprises. From the perspective of product development, China still basically stays in the test imitation stage, and its self-development capability is weak. It lacks the research and production pilot base, and research funds only account for 1% of sales. 8% to 10%.
