Paper bag machines are often mechatronic devices that require the fullest use of information products. Some planners of domestic companies are unfamiliar with electronic goods, and dare or not choose, which greatly restricts the improvement of the level of paper bag machines.
For example, many foreign paper bag machines mostly use separate transmission, which can greatly shorten the transmission chain of the whole machine, greatly simplify the structure, and greatly improve the precision and speed. One of the core skills here is the multi-motor drag synchronization tool paddle mixer, pneumatic mixer, high shear mixer, mixing mixer, and mixing mixer. It is not difficult to grasp this skill. Only some planners I don't know the intent of this development of packaging machinery. Another core skill is that many servo drives are used, but the old planners will not plan and choose the servo mechanism and its control system.
Many of the leading paper bag machines use a number of new inspection systems to ensure the stability and reliability of the paper bag machine. With the addition of professional penetration and the development of information skills by automation vendors, the increasing number of planners are taking advantage of leading automation skills and using leading automation products to enhance the functionality of the equipment.
We must bear the reality that China's paper bag machine is behind the developed countries, and the fundamental reason is that key skills cannot be grasped. Therefore, in the future development experience, domestic manufacturers urgently need to improve their own skill level and planning concept.
The main forms of heat-sealed bags are hot plate type, pulse type, high frequency type and ultrasonic type.
(1) Hot plate type heat sealing. This is the most common heat sealing method in which the film 3 to be sealed is pressed between the heat-resistant rubber 4 and a heating plate heated to a certain temperature (constant temperature control) to achieve heat sealing. The heat sealing machine has the advantages of simple structure and principle, and fast sealing speed, so it is widely used for heat sealing of polyethylene film and polyethylene composite film. However, it is not suitable for heat sealing of a film which is easily contracted or decomposed by heat.
(2) Pulse heat sealing. For example, a nickel-chromium alloy strip film is pressed on a heat-resistant rubber, and a nickel-chromium alloy strip is instantaneously applied by a large current, and the heat is used for sealing. It is characterized in that the nickel-chromium alloy strip leaves the heat-sealed portion after being cooled, so that even a film that is easily deformed can be heat-sealed by this method. This method is suitable for the sealing of products requiring high sealing strength and sealing properties. For example, the packaging of items with a lot of water and the sealing of vacuum packaging. This method is generally suitable for intermittent sealing.
(3) High frequency heat sealing. It is suitable for high-frequency electrode pressing film, plus high-frequency voltage, heat-sealing by dielectric loss of polymer. The sealing portion has the highest sealing surface, so the film does not overheat and the sealing strength is high.
(4) Ultrasonic hot air. This hot air mechanism is composed of a high frequency oscillator, a magnetostrictive vibrator that converts high frequency electric energy into longitudinal vibration, and an exponential curve type amplitude amplifier that transmits longitudinal vibration to the film. The ultrasonic vibration transmitted by the exponential curve type amplitude amplifier during heat sealing causes the laminated surface of the film to generate heat and melt and bond. This heat sealing method is characterized by heat generation at the center of the film lamination, and is suitable for continuous sealing of heat-shrinkable films such as biaxially oriented films.
The automatic paper bag machine is made of primary color or printed flat sheet of paper. It is a hoisting device for making a square bottom paper bag. The process flow is roughly as follows: the flat sheet after printing (or film coating) is transported to the pull gauge part by the automatic paper feeder for positioning, and the rolling equipment is used to feed the pressure line, and then transported to the open bottom part by the transport device. Press the transverse line, open the bottom, glue, press and finally output the finished paper bag. (Mechanical speed differs depending on the quality of the paper, the weight of the paper, the printing effect, whether it fits the pp film, the quality of the adhesive, the paper standard, the climate, and the job shop environment.)
The characteristic paste paper bag is an old-fashioned handicraft industry, which is environmentally friendly. Nowadays, the portable paper bags have been printed and have become a variety of high-end goods packaging or gift bags. The plan for paper bags is generally very concise. As an extension of the merchandising strategy, an outstanding corporate image is the key. Nowadays, the concept of continuous addition is used on paper bags, and various fun pictures are printed on the paper tape, making the days quieter and more interesting.
The parameters of the portable paper bag plan, the standard of the shopping bag plan principle, the top edge of the paper bag is folded 60mm, which is used to strengthen the handle fixing force. The width of the bottom edge of the paper bag is 15mm to strengthen the load-bearing force of the bottom of the bag (the side width is reduced by 15mm). The paper bag is almost 30mm, and it must be on the right side.
The finished shopping bag should be provided with 2 folding bags, 6 top edges, 6 bottom edges and other folding bag symbols to facilitate accurate forming of the paper bag. Shopping bag production standards, to meet the number of paper open, in order to benefit economic benefits. The paper is oriented parallel to the "high" of the paper bag to facilitate the folding of the paper.
The paper bag machine is large-scale and group-oriented. The production capacity of concentrated enterprises will continue to develop towards large-scale and group-oriented, in order to pursue economies of scale. Under the current situation that the capital and technical strength are not strong enough, small and medium-sized enterprises should not blindly introduce production lines, and can adopt the mode of providing spare parts production for large machinery enterprises.
The new situation of paper bag machine exports. China's pharmaceutical and packaging machinery technology is moderate, cheap and good, and is very suitable for the economic conditions of developing countries and regions. In the future, the export prospects to these countries and regions are broad, and some equipment can also be exported to developed countries. For example, automatic steamed bread machine, sales are good.
Improve the technical content of the paper bag machine. There is no good technology as the backing for the development of the company. Realize the development of mechatronics and intelligence to product information and introduce new technologies. Further improve the technical level, stability and reliability of the equipment. Be brave to face the reality, actively change this state, improve product development capabilities, and form your own innovation ability, in order to catch up.
Strengthen the development and innovation of new products in paper bag machines. China's packaging machinery is mostly developed on the basis of imported equipment. For large gaps with foreign countries or blank products, we should actively introduce technology, digest and absorb, and gradually understand and fully grasp. We will learn from the products that have a certain foundation but have a certain gap with similar foreign products, strengthen research on relevant key technologies and core technologies, and encourage development and innovation.
To see it, there are two main ways to follow the paper feeding method of the square bottom portable paper bag machine in the domestic market: this is also to help us to achieve a kind of roll-type portable paper bag machine; can be used It is a single-sheet portable paper bag machine. The natural thing is to have both devices have active paper feeding, and we have to see that after active sizing, active paste. This is to make the goods look good.
Second, the product bag making needs to post a bottom paper at 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 we can solve the problem of the traditional paper bag machine.
No matter which type of paper bag machine is the original type of equipment in the production of packaging machinery. The effect of these devices is to make the simple packaging more fast and convenient, and to provide more help for the consumer's belt and packaging. This is the effect of the bag making machine.
The meaning of the paper bag machine is to make the traditional packaging more convenient and more convenient, and the packaging is to become lighter, and it is also convenient for the convenience. The occurrence of the paper bag machine has enabled the traditional packaging to be unfolded and unfolded into a one-time rapid packaging and carrying, and then embodied as an environmental concept.
Relatively speaking, this kind of expansion not only makes the packaging machine bigger and better, but also the packaging machinery of other materials has been well developed, becoming the mainstream packaging equipment in the shopping mall, which has a dominant position in the shopping mall. effect.
