Abstract
The utility model discloses a molding device for an easily torn line. The molding device comprises a winding roller arranged at head and tail two ends, a tension roller, a driving system and at least two sets of synchronously acting punching tools, wherein each of the two sets of punching tools comprises a straight supporting plate and a punching mould with cutting teeth being of comb tooth shape, and all the cutting teeth are arranged in a form of being opposite to the straight supporting plate. The molding device for the easily torn line is provided with more than two sets of synchronously acting punching tools, so that the production efficiency is obviously increased. Besides, compared with a laser nicking device, the molding device has the advantages of lower cost and less capital investment of the production line.
Description
Technical field
The utility model belongs to the soft package technology field, is specifically related to a kind of easy-torn line former.
Background technology
Traditional common flexible packaging film is not easy to be torn in use, even and after tearing, it is smooth that the place of tearing can not keep, cause using very inconvenient, also influence impression.
At present, occurred having the flexible packaging film of easy-torn line on the market, for example patent documentation CN1608951Y discloses a kind of method for making of soft packaging bag tearable mouth, and this method may further comprise the steps:
(1), designed patterns is input in the computer system; (2) control laser cutting system with computer system; (3) laser beam irradiation that described laser cutting system is generated is to the one side of soft packaging bag diaphragm seal, and described laser beam carves or cut into the line of weakness of corresponding pattern moulding in the one side of soft packaging bag diaphragm seal according to designed pattern; (4) described tearable mouth is formed according to line of weakness.
There is following weak point in this kind method: laser machine price is higher, and the manufacturing line infusion of financial resources is many; Because in most of technologies, film direction of travel and line of weakness direction be in same direction, so laser head must move the line of weakness that just can complete behind the certain distance, this rate travel is slower, loses time reduction production efficiency; The principle of laser beam indentation is to utilize the high temperature sintering film and form indentation in fact, so can produce niff, causes large quantity of exhaust gas.
The utility model content
The purpose of the utility model provides the easy-torn line former that a kind of tool obviously promotes production efficiency.
The technical scheme that realizes the utility model purpose is: a kind of easy-torn line former; The punching tool that comprises the take up roll, jockey pulley, drive system and at least two cover synchronization actions that are arranged on the head and the tail two ends; Each overlaps punching tool and comprises a straight supporting plate and a punch die that is provided with the cutting of broach shape, and each cutting is over against straight supporting plate setting.
Said each cutting is a rectangular teeth.
The utlity model has positive effect: (1) the utility model equipment is owing to have the punching tool of the above synchronization action of two covers; Can obviously promote production efficiency, in addition, this kind equipment and laser scored apparatus in comparison; Price is comparatively cheap, and the manufacturing line infusion of financial resources is less.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model product;
Fig. 2 is for adopting a kind of structural representation with complex film of easy-torn line of easy-torn line former shown in Figure 1 manufacturing;
Fig. 3 is a kind of cutaway view of complex film shown in Figure 2.
Be labeled as shown in the accompanying drawing: polyethylene terephthalate rete 1, polyethylene film layer 2, indentation 3, take up roll 51, jockey pulley 52, punching tool 53, supporting plate 531, cutting 532, punch die 533.
The specific embodiment
(embodiment 1, easy-tear type composite package film)
Fig. 1 to Fig. 3 has shown a kind of specific embodiment of the utility model, and wherein Fig. 1 is a kind of structural representation of the utility model product; Fig. 2 is for adopting a kind of structural representation with complex film of easy-torn line of easy-torn line former shown in Figure 1 manufacturing; Fig. 3 is a kind of cutaway view of complex film shown in Figure 2.
Present embodiment is a kind of easy-torn line former; See shown in Figure 1; The punching tool 53 that comprises the take up roll 51, jockey pulley 52, drive system and at least two cover synchronization actions that are arranged on the head and the tail two ends; Each overlaps punching tool 53 and comprises a straight supporting plate 531 and a punch die 533 that is provided with broach shape cutting 532, and each cutting 532 is provided with over against straight supporting plate 531.Each cutting 532 is rectangular teeths.
Present embodiment can obviously promote production efficiency owing to have the punching tool of the above synchronization action of two covers, in addition, this kind equipment and laser scored apparatus in comparison, price is comparatively cheap, and the manufacturing line infusion of financial resources is less.
Fig. 2 and Fig. 3 have shown a kind of application mode of present embodiment, and the polyethylene terephthalate rete in this kind composite package film is processed for adopting present embodiment.Specifically, this kind composite package film is composited by polyethylene terephthalate rete that is used to strengthen 1 and the polyethylene film layer 2 that is used to seal; Said polyethylene terephthalate rete is provided with the destructive indentation 3 of discontinuous, and forms easy-torn line at these destructiveness indentation 3 places.Said destructive indentation is the poroid indentation 3 that on polyethylene terephthalate, forms through die-cut mode.Because the higher polyethylene terephthalate rete of intensity is by the poroid indentation in the die-cut place of the cutting on the punch die; The polyethylene film layer of effect is torn in the more weak influence hardly of intensity and aluminium foil layer is then complete remains; Both had good sealing effectiveness; Can just can tear with very little power again, form the regular shape opening of tearing along line of weakness, have excellent in-use performance along the easy-torn line that is provided with indentation.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the embodiment of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection domain of the utility model.
Claims (2)
