The first paper bag machine paper bags are fixed-length sealed and cut. The positioning system is a fixed-length positioning system. Only the speed of the sealing and cutting action can match the speed of the bag feeding to meet the requirements of fixed length sealing and cutting; the other is the printing bag positioning system and printing bag. The positioning system is a positioning rod and must require that the position of each seal fall on the designated mark position.
        When performing various sealing and cutting tasks, problems inevitably arise; that is, the length of luggage requested for each task may change, which will inevitably affect the initial value of luggage that we preset in the system. Moreover, since the interval S between the photoelectric eye and the seal cut of the paper bag mark is set to a constant value, the length of the bag is changed, which inevitably affects the relationship between the feed speed of the bag and the sealing and cutting speed .
         Therefore, in order to realize the active positioning of processing, a certain functional adjustment must be made between the length of the bag and the interval S. But this is only used to seal and cut printed bags, but it makes sense when it can't seal paper bags. In the packaging production industry, composite thin bags used as packaging bags can be divided into two types: one is a paper bag, and the other is a printed bag (color bag). Photoelectric signal detection sensors are printed on the colored bags to identify other signs.
        The active positioning system of the sealing and cutting machine actively checks the frequency of the sealing and cutting machine controlled by the main motor through the photoelectric signal sensor, and then converts the number of pulses to the number of pulses detected by another photoelectric signal sensor, and adjusts the feed of the stepper motor. Frequency to achieve change. The feed speed is suitable for the sealing and cutting movements of the main motor.

        Paper bags are increasingly used in people's lives. Today, people need such paper bags at work. China envelope bag making machine is specially used for making various envelope paper bags. Such machines and equipment can produce a large number of document bags, medicine bags and envelope paper bags, etc. These paper bags can meet the needs of many users after production, and are very popular and useful in people's work.
        The Chinese envelope paper machine is mainly used for die cutting work. The equipment has die cutting tools, which can be adjusted, and the corresponding size can be adjusted. The function of the adjustment is to make the paper bag more suitable for the use process and meet the needs. every aspect.
        China Envelope Paper Bag Machine can produce and process various specifications of envelope bags. It is a special equipment that specializes in producing Chinese envelopes. Its production efficiency is high, the equipment performance is stable, and it is easy to adjust. It is the best choice for many manufacturers.
        This device can solve the problem of torch prone to the bottom of the seal. The equipment has reasonable valve distribution and advanced gas circuit. Easy to clean and operate. It is mainly used to produce large and medium envelopes. There are many types of envelope bag machines, which will be divided into automatic multi-function envelope bag machines, sharp-bottom paper bag machines and square-bottom paper bag machines, etc. according to the different characteristics of their use. Different classifications will produce different effects.

         The square bottom portable paper bag machine is mainly used for packaging of clothing products, packaging of boots products, various gifts, corporate image promotional bags, etc. What is the development trend of portable paper bag machines? There are two main types of hand-held paper bag machines on the market: one is a roll-type hand-held paper bag machine; the other is a one-piece hand-held paper bag machine.
        Both devices have features such as automatic paper feeding, automatic gluing, automatic underlaying, and automatic output.
        However, there are still some disadvantages.
        First, after the finished paper bag is finished, there are dents on the front of the paper bag, which affects the aesthetics of the product.
        Second, the finished paper bag needs to be manually spread on the bottom of the bag with a base paper to improve the bottom strength of the paper bag.
        Third, the paper bag handle needs to be manually pasted.
        Fourth, the production efficiency is low, about 40-60 per minute.
        Fifth, the range of adaptable paper is limited, and the paper weight is between 70-200g / m2.
        Because the square bottom portable paper bag machine is easy to carry and easy to degrade, it can not only recycle recycled paper, but also reduce air pollution and environmental protection, so it has become one of the most useful green environmental protection products.
        The development of paper bag machinery shows a tendency to combine mechanical, electrical, gas, liquid, optical and magnetic. Production of high-efficiency, energy-saving, recyclable products, high-tech practicality and intelligence has become a trend.

        What is the role of fruit bagging? Fruit bagging can prevent or reduce the destruction of various diseases, insects and birds, reduce pesticide residues and air pollution, improve appearance, improve fruit quality and commercial value, and is one of the important means of producing green food in developed countries. It can be said that bagging is an important part of modern agricultural fruit production technology.
        Specifically, fruit bagging has the following effects:
        1. Prevent (or reduce) disease, insects and birds. According to the survey, many fruits can completely prevent various pests such as diptera pests, slime insects, lepidopteran pests, fruit moths, coleoptera pests, gold beetles, beetles and hemiptera pests. Class, etc. The control effect on fruit bats and birds also exceeds 95%. In addition, in recent years, the incidence of brown rot and black spot disease (spot disease) and soot dust has been greatly reduced, bagged disease has been reduced by 78.9%, brown spot disease by 71.2%, and soot dust. The disease was reduced by 68%.
       2. Improve appearance and promote coloring. The coloration of fruits during maturation is mainly composed of chlorophyll, carotenoids and anthocyanins. Leaf leaves are formed during fruit expansion and the latter two are formed during maturity. After bagging, it can significantly inhibit the synthesis of chlorophyll and promote the formation of carotenoids and anthocyanins in the dark environment. As a result, most fruits are colored more quickly and evenly after bagging in the middle and late stages. At the same time, because the fruit grows in a relatively stable environment after bagging, it is not affected by external pollution, friction and damage, resulting in cell growth and tenderness, smooth and smooth skin, and bright color.
        3. Reduce pesticide residues. Fruit bagging can reduce the number of sprays and greatly reduce pesticide residues. According to the data, the comparison between bagging and non-bagging reduced the residual by 45-84.85% after 7 days of spraying with 50% methamidophos.
        4. Reduce pollution. At present, the common harmful substances in the air are sulfur dioxide, fluoride and some dust and fly ash containing heavy metal elements. Sulfur dioxide and fluoride are extremely detrimental to crop growth. Lighter chlorosis and severe browning and necrosis. In addition to causing damage to crops, atmospheric pollution containing heavy metals can promote the reproduction of certain pest populations and cause pests. Bagging can greatly reduce the above-mentioned pollution, and can effectively improve the appearance and commodity value.

        1. The high-speed paper bag machine solves the problem of manual priming paper by manual paper bag machine. Traditional hand-held paper bag machines are not only slower at the bottom, but their quality cannot be guaranteed. A machine requires several people to match the bottom, which is caused by inconsistent machine speeds. Yields can never be improved, and labor costs are high. A backing sheet must be applied manually from the inside of the bottom of the paper bag. This method has a slow bag making speed and poor bag making quality. The portable paper bag machine can automatically paste the bottom, automatically paste reinforced paper, and technological innovation, which reflects the automation performance of modern machinery.
        2. The high speed paper bag machine solves the problem of indentation on the front of the traditional paper bag machine. Due to the relatively backward manufacturing process, the paper bag made by the traditional paper bag machine has not been well solved due to the indentation problem. This is a big problem. The front of the paper bag is always indented, which affects the appearance of the paper bag. This machine adopts innovative design to solve the problem of indentation on the side of the paper bag. The product is of good quality and exquisite appearance. This is the benefit of technology upgrades.
        3. High speed paper bag machine solves the problem of narrow application range of traditional paper bag machine. The paper square weight of traditional square bottom paper bag machine is 70-200g / m2. Now the new strip paper bag machine breaks through the technical limitation, and the paper weight range reaches 70-350g / m2, which is basically suitable for various types of square bottom portable paper bags on the market. Only by meeting the needs of more people. This bag can really replace the heavily contaminated plastic bag products.
        4. High-speed paper bag mechanism is faster. Due to the limitation of the production process, the bag making speed of the traditional paper bag machine is 40-60 per minute. Although not slow, it will show its disadvantages if it is mass produced. Now the new long paper bag machine can produce 80-120 per minute, and the speed is doubled. This can save a lot of time and reduce the cost of operating a business when producing a large number of orders.
