Large bags at home and abroad and equipment selection method outlined
. Packaging designed for such equipment relative maturity, there is only the packaging process, in addition, sewing, trimming braid, combination,[link widoczny dla zalogowanych], cooling and counting processes, automatic control by the PLC to complete. And the design of sewing machine broken, broken tape, card, chain, overload, such as failure of the warning system to avoid the leakage of high-speed production batches, drain the package errors and ensure production safety. In addition, the appropriate time to pin down stay with the only point of safety devices and can achieve instant sewing machine motor rated speed of the clutch device. The Office-style automatic packaging machine used electromechanical integration,[link widoczny dla zalogowanych], computer control of advanced technologies, institutions improve, mature technology, is widely used internationally advanced equipment. 4, folding paper bag mouth sealing automatic packing. There are three different ways such packaging, but they are first off the bag and then seal and their own strengths, is currently more popular in the United States and Europe. Such packaging as required, within the discussion of a plastic bag inside r, it may not lined bag. Are respectively introduced as follows: (1) paper folding automatic packaging hot mouth. Such paper envelope made of a similar Chinese pocket, side of the tongue for the single or multi-layer bags, a hot melt adhesive coating surface, pocket sealing process is: open pocket warm-up inside the bag, through the outer sealing liner bag, indentation, folding bags tongue, pressing, sealing, cooling and other processes. Temperature adjustable, stepless speed, full automatic control. Such bags can also be designed with one-way exhaust valve when the exhaust gas in the entire package to prevent the pressure when the blast bags. This packaging meets the requirements of the packaging functions, but the bag making process more difficult, promotion and application of r constraints. (2) paper tape sealing off port side of the automatic packaging. The packaging and the packaging difference is that the bag is flat on both sides, according to the requirements of packaging, paper bags can also be a multi-layer, the pocket can be folded once or twice. The process of this package are: dust, heat sealing the bag, rolling, cutting inside the bag, indentation (one or two), off I (once or twice), the side of the glued paper tape, paper cutting zone, pressing, cooling. Part of the packaging equipment sector is more complex, increasing the difficulty of manufacturing. (3) paper folding port package with automatic packaging. Packaging process of this approach is: first, sealing the bag, and then the indentation, folding bags u, then folded into a saddle bag on the hot women of China Packaging 2005 / 4 melt adhesive tape, after cutting zone, heating, pressure co. This packaging has the above six functional requirements, the dissolution of bags especially convenient. And packaging designed for such equipment is already quite mature, the use of electromechanical integration technology, temperature control, frequency control, institutional improvement, advanced technology, a new generation of packaging equipment. Through practice and user surveys, believes that , mature technology, stable and reliable continuous operation,[link widoczny dla zalogowanych], in line with our national conditions and by the majority of users. The two devices can be matched with the automatic production lines, continuous measuring, filling, bagging, exhaust, sealing, conveying,[link widoczny dla zalogowanych], shaping, stacking and other processes, efficient high-quality packaging. The past 20 years, the design of large bags and the corresponding packaging equipment innovation, emerging, in addition to the above-mentioned relationship with the larger packaging machinery types without repeat. Indeed, a good way of packaging requires appropriate packaging and advanced packaging equipment and packaging design and production of bags are also essential. Low-cost high-quality packaging is the company to chase the target, but the bag does not quite understand business processes and use of packaging, packaging bags produced are often not noted by some aspects of which fail to packaging requirements, would like to draw attention , bags should be packed in six functional requirements to achieve the above premise, select the appropriate packaging materials and production process. Multi-layer paper bags and paper bags are lined on the production of plastic bags, put forward the following requirements for bag making enterprises and enterprises with the bags and complete sets of equipment suppliers reference: l, multi-layer kraft paper bags can be lined with plastic, between layers must be closely nested, the inner than the outer dimensions may be a slight interference, without gaps in order to play the role of multi-tolerance. 2, lined with plastic is not too large, so as not to wrinkle generated when the stack and seal leakage. 3, not less than the thickness of plastic bags lined 0.06ram, otherwise,[link widoczny dla zalogowanych], is not easy to cut off the pocket trim, and even damage to the cutter. 4, if necessary dust bag, the bag must be part of the adhesion between layers. 5, M-fold paper bag without liner for sewing, folding at the sides of M should be adhesions. 6, lined with plastic packaging, should be upholstered way, not using composite bag, paper-plastic bags is not easy due to degradation. The full realization of the above requirements may need a process, but we should take the lead in advocating the packaging industry, packaging and packaging equipment for our development with the world, reached the international advanced level.
