Abstract

The present invention relates to a kind of close wrapping shell of liquid that is coated with the composite material of cardboard of plastics, it has a vertical face of joint.In order to obtain straight flange, the edge strip (4) of the layer in being configured in face of joint is when being folded, at first in the narrow interior zone of the fold line of the edge strip that is folded, remove composite material (7), adopt cheap equipment just can accurately finish the removal of this material in burst.This has just realized forming at the folding position of the edge strip that is folded the preparative treatment of straightedge.

Description

Close wrapping shell of the liquid of combination board material and manufacture method thereof
The present invention relates to the close wrapping shell of a kind of composite wood feed liquid, it comprises cardboard and covers the heat seal plastic coat of its both sides, and has a vertical face of joint that on the synthetic material internal layer, processes, the edge strip of folded-out sealing-in, with edge strip and outside the side cut of internal layer and edge strip the skin of the composite material of sealing-in.
The invention still further relates to the method for making this shell, before edge strip is folding, composite material wiped off, edge strip is folded into wiped off the composite material side and with the edge strip sealing-in after, with internal layer sealing-in outer and edge strip and adjacency.
Making the close difficulty of packing used shell of liquid with independent coiled material or sheet material is to make vertical face of joint, because the restoring force of composite material does not particularly have the aluminium synthetic material, it is impossible accurately folding along broken line when composite material is not pretreated.
In existing a kind of method (DE4036454A), the composite material on the whole width of edge strip is all ground off, only remaining ply of board and plastics covering then, fold the zone that grinds off composite material.This method must be used special grinding knife tool, because they only are to obtain step transition between the zone that does not grind off and grind off synthetic material, not has difference with the pretreatment on smart limit.
What another was known is to wipe off at the composite material of edge strip zone and the adjacent domain behind broken line with cup-shaped hilt, and grinding goes out groove on broken line afterwards.In a word, it is impossible carrying out folding accurately along the broken line that does not have grinding to go out groove.This manufacture method also needs to use expensive cutter.
The objective of the invention is provides a kind of shell to the close packing of the liquid of combination board material, and it has straight vertical face of joint, and available than the prior art more cheap tool production of inexpensive method more.
The characteristics that the present invention addresses this problem are, composite material is removed from the surface of the narrow interior zone of the burst that is limited to folding edge strip.Specifically by burning or preferably wiping described material off and remove.
Be suitable for producing in a kind of method of this shell, before folding edge strip, the composite material of fold domain is wiped off, then edge strip is folded into that side of wiping composite material off and carry out sealing-in, composite material sealing-in outer and edge strip and adjacency, synthetic material has been wiped off in folding narrow zone.
For example can the composite material on surface be burnt and remove composite material by laser beam, yet, preferably adopt the method for machinery that composite material is scraped off.If along the flange of a composite material of fold line formation, more specifically saying so processes a groove, then composite material is scraped off, just can carry out the scraping operation especially simply.
The most handy cup-shaped cutter carries out scraping, and this moment, composite material leaned against on the stable element, and this stable element contacts with the groove of flute profile flange, makes flute profile flange and cup-shaped cutter centering.Suitable stable element is a grooved roller.
In order to be more convenient for carrying out the folding operation of edge strip, after removing composite material before the folding edge strip, process a flange that exceeds the side of removing composite material in the zone of removing composite material.
Being limited to composite material in the folding narrow zone is slackened and guarantees and can accurately fold along the broken line that is provided.Even have under the situation of big restoring force as no aluminium composite material at composite material, folding operation and later sealing-in can not go wrong.In a word, composite material is scraped off, do not need with expensive scraping or grinding tool in the whole zone or the following described again zone of edge strip.If before scraping, make raised ledge, adopt the hat cutter scraping more cheap then than grinding tool, can soon shell be created.Because the present invention guarantees even still can obtain straight seamed edge after folding edge strip and sealing-in, has satisfied accurately producing vertically
The condition formerly that face of joint is required.
With reference to the accompanying drawings the present invention is done more detailed explanation, wherein,
Fig. 1 is the cross sectional drawing of vertical face of joint of shell
Fig. 2 a to 2g shows the different step of making longitudinal surface, and it both can regard used technical equipment as also can regard product therefrom as.
With reference to Fig. 1, the used composite material of pack case comprises the plastics covering of the heat seal mateiral of cardboard and its both sides, and as polyethylene cover: the weight of composite material unit area is 200-250g/m 2Be configured in internal layer 2 in vertical face of joint 1 zone of shell and be coated with the skin 3 of composite material, the edge strip of internal layer 24 folded-out and with the outside sealing-in of internal layer 2, outer 3 with edge strip 4 and the contiguous internal layer 2 and the side cut sealing-in of edge strip 4.By scraping off, the composite material at this place is slackened at the composite material on the surface in the narrow zone at folding position 6.
In order to form described vertical face of joint, through the step shown in Fig. 2 a, composite material 7 is passed through in the middle of having groove and becoming roller 9a, the 9b of slotted disk from a pair of, on composite material 7, form raised ledge 8.
In second step (Fig. 2 b), composite material 7 is through cup-shaped cutter 10 processing of a rotation, and running roller 12 makes composite material and hat cutter 10 centerings, and running roller 12 contacts with the groove 11 of material 7, has played the effect of stable element and guiding.
At next procedure (Fig. 2 c), composite material 7 has groove and the roller 13a that becomes sheave and 13b processing through a pair of again, forms new raised ledge in a side of removing composite material.Described new flange 14 helps to carry out folding operation at the composite material 7 upper edge fold lines that slackened.
In next procedure (Fig. 2 d), utilize Foldable tool to fold edge strip 4 with folding rod 15.Then, make composite material 7 be pressed into shape with giving by pair of rolls 16a, 16a through folding edge strip (Fig. 2 e).
For the folding edge strip 4(Fig. 2 f of sealing-in), make the activation of plastics (polyethylene) layer, therefore, in next procedure (Fig. 2 g), can edge strip 4 be attached on the region of activation of composite material 7 in the folding station that the next one has belt guiding 18a, a 18b.
(Fig. 2 h) at last passes through edge strip 4 between pair of rolls 19a, 19b, thereby pressurized.
The further modification of composite material and outer 3 is finished according to customary way with the sealing-in of edge strip 4 and internal layer 2.
