Abstract
The invention provides a method for manufacturing a continuous coiling garbage bag with a plurality of wavy bag openings. The method comprises a process of blowing a plastic film into a film bubble by using a film blowing machine. The method is characterized by also comprising the following processes: inserting the film bubble to be a four-layer structure by using inserting boards at both sides of the film bubble, and sealing and cutting the finally folded film bubble in a bag manufacturing machine, wherein in the process of sealing and cutting the finally folded film bubble in the bag manufacturing machine, heat sealing is carried out on the film bubble, a precut straight line is set, and then a precut line is set on the film bubble between two adjacent heat sealing lines. Because in the invention, the bottom of the film bubble is sealed by weld lines after the film bubble is folded, the width of a sealing tool and a cutting tool required in the bag manufacturing process is shorter. The method provided by the invention has higher efficiency and saves energy.
Description
Technical field:
The present invention relates to the mankind life article, relate in particular to package packing supplies, particularly store the manufacture method of the plastic film bag of rubbish, concrete is a kind of manufacture method of refuse bag of the plural waveform sack that batches continuously.
Background technology:
In the prior art, in the vest type refuse bag of the band of baling system mouthful handle, the upper end-face edge place of the bag that each plastic film bag constitutes is provided with two outstanding handle parts.Before using, a plurality of upper ends without the refuse bag that uses link to each other with bottom order successively, and its junction is provided with unsegregated precut line, and a plurality of the coiling without the refuse bag that uses deposited.During use, isolate independently refuse bag from precut line, be placed in the dustbin after launching, the bag edge turnover of plastic film bag is on the upper end open of dustbin wall.After being filled with rubbish, two outstanding handles are partly intersected knotting, make the sack sealing.But the vest type refuse bag work in-process that two outstanding handles are set compares waste material, because two outstanding handles form by cut one on a flat pocket body, the plastic sheeting that cuts is wasted, and perhaps needs to expend the energy and melts down the granulation use again.In addition, the bottom of general flat mouthful of refuse bag is 2 tunic structures, general vest pocket type refuse bag middle body 2 tunics and both sides are the unbalanced construction of 4 tunics.Place all leakiness of the big or rubbish that contains liquid of density.And through folding, the refuse bag width of rolling is not bigger for refuse bag, stores inconvenient.
Summary of the invention:
The object of the present invention is to provide a kind of manufacture method of refuse bag of the plural waveform sack that batches continuously, the manufacture method of the refuse bag of the described this plural waveform sack that batches continuously will solve light, the inconvenient technical problem of storage of refuse bag procedure of processing complexity, waste material, load-bearing in the prior art.
The method that a kind of structure of the refuse bag of making the above-mentioned plural waveform sack that batches continuously is provided of the present invention, described method comprises that an employing inflation film manufacturing machine blows plastic sheeting the process of film forming bubble, comprise that also the both sides at film bubble adopt the insert edge plate that film is steeped the process that insert edge becomes four-layer structure, comprise that also one becomes the doubling of four tunics bubbles into eight layers process, the process that also comprises Bag Making Machine back cover and otch on the film pipe after folding, on film after described will the folding bubble in the process of Bag Making Machine back cover and otch, on the film pipe, select suitable length to seal and be provided with precut straight line, in two adjacent centres that seal lines of film bubble precut line is set then.
Further, behind blowing film forming bubble, comprise one will be two-layer film steep " Z " type and be folded into 6 layers process.
The precut line of the undaform of a projection further, is set in the centre of adjacent two heat-sealing lines of film pipe.
The precut line of an oblique S type further, is set in the centre of adjacent two heat-sealing lines of film pipe.
Concrete, according to the number of plies of plastic film bag longitudinal folding back formation and the permutation and combination of cutting profile, can form 2 crest shapes and 2 trough shapes commonly used, perhaps 4 crest shapes and 4 trough shapes, perhaps 6 crest shapes and 6 trough shapes.
Because different precut wire shaped, above-mentioned Wave crest and wave trough shape can be that similar sinusoidal curve constitutes, and also can be to be made of broken line.No matter which kind of shape.Outstanding crest can be as intersecting knotting so that the sack sealing.
Operation principle of the present invention is: in any one plastic film bag group, the shape of the upper end-face edge of two plastic sheeting bags is a plurality of crest shapes and trough shape, and in each group sack, the crest of a sack is the wave base of another one sack.So the upper end of two plastic sheeting bags can cooperatively interact, seamless connectivity.When the user uses, two continuous bags are separated along wavy precut line.Be placed in the dustbin after bag launches, a plurality of crest shape protuberances of bag upper end can turn down on the upper end open of dustbin wall, be filled with rubbish after, a plurality of crest shape protuberances are intersected knotting, can make the sack sealing.
The present invention and prior art contrast, and its effect is actively with tangible.The upper end-face edge shape of the single refuse bag of the present invention is set to be a plurality of crest shapes and trough shape, the upper end of two refuse bags is interconnected, utilize wavy precut line that two continuous bags are separated, in the process, can not waste plastic sheeting, in addition, bag is placed in the dustbin after launching, a plurality of crest shape protuberances of bag upper end can turn down on the upper end open of dustbin wall, after being filled with rubbish, with the knotting of a plurality of crest shape protuberances intersection, can make the sack sealing, use very convenient.Because the present invention is after the bag film is folding, seal by weld bond in the bottom of bag film simultaneously, so the bottom number of plies of refuse bag of the present invention is more, intensity is big again, and it is also no problem to place the big rubbish of more density.And it is narrower through folding caudacoria pipe width.During last Bag Making Machine bag, because the width of back cover and cutting is little, perhaps can use littler Bag Making Machine manufacturing, perhaps the Bag Making Machine of width can be made two lines simultaneously equally.Bag efficient is higher, and is more energy-conservation.Because refuse bag so the volume of the refuse bag after the rolling is wide narrower, stores convenient through rolling again after folding.
