Description of drawings
Fig. 1 is the structural representation of valve bag preferred embodiment;
Fig. 2 is the perspective view of copper tool preferred embodiment;
Fig. 3 is the birds-eye view of copper tool.
The specific embodiment
With reference to the accompanying drawings the preferred embodiment of the present invention is described in detail.
With reference to shown in Figure 1, in this preferred embodiment, valve bag comprises bag 10, potted line 11, clip chain 12, tearing notch 13, easy-torn line 14.
Wherein, valve bag is a rectangle, and bag 10 is a double-decker, three limit sealings of this bag 10, not having limit of leak free is opening, is provided with clip chain 12 in the bottom of opening, this clip chain 12 is arranged on the inwall of double-deck bag 10, and during use, clip chain 12 can be opened easily with closed.In the bottom of clip chain 12, on each face of bag 10 two easy-torn lines 14 should be set at least, this easy-torn line 14 both can be arranged on the inwall of bag 10, also can be arranged on the outer wall of bag 10.By the tearing notch 13 between easy-torn line 14 and two easy-torn lines 14, can along easy-torn line 14 bag 10 be torn easily, and in the process of tearing, can not become rail.
In this preferred embodiment, respectively be provided with 12 easy-torn lines 14 on each inwall of bag 10, the distance between per two easy-torn lines 14 is 1 millimeter, is provided with tearing notch 13 between the easy-torn line 14.When realization is easily torn, in order to allow easy-torn line 14 also play the leak free effect, in this preferred embodiment, depart from mutually between the easy-torn line 14 on two bag 10 inwalls, make every easy-torn line 14 on a side pocket body 10 inwalls be pressed between two easy-torn lines 14 on the opposite side inwall.Owing to be provided with many easy-torn lines 14, on internal face, form a corrugated surface, prolonged the length of internal face, the easy-torn line 14 of adding in the present embodiment is the triangulo column structure, one of them face is connected with the inwall of bag, the rib and the internal face of easy-torn line 14 contact, thereby realize sealing, can effectively block spilling of liquid in the bag 10.
The distance that the easy-torn line 14 of each side of bag 10 is provided with between 13, two tearing notches of two tearing notches is 3 millimeters, and each tearing notch 13 is arranged on the side of bag 10, between two easy-torn lines.Certainly,, can be provided with a plurality of tearing notches 13 by easy-torn line 14, be beneficial to conveniently tear along with the increase of easy-torn line 14.
For more effectively leakproof, in this preferred embodiment, above clip chain 12, also be provided with two sealing lines 11 on the inwall of bag 10, another inwall is provided with four sealing lines 11, with the homotaxy of easy-torn line 14, depart from mutually between the potted line 11, make that the potted line 11 of wall is pressed between two sealing lines 11 of another internal face one by one, like this, also can play the liquid that prevents in the bag 10 and spill.
In this preferred embodiment, skin at bag 10 is provided with first extra play, the opening of first extra play and the opening of bag are equidirectional, three outer edges of other extra play and airtight connection of outer wall outer edge of bag 10, bottom at clip chain 12, the skin of first extra play is provided with second extra play, and the opening of this second extra play is opposite with the opening of first extra play, second extra play cover first extra play above.By first extra play and second extra play, the explanatory note of the specification of product or title and so on can be placed in the space that forms between first extra play and bag 10, can conveniently realize product classification like this.Because the opening of first extra play and second extra play is opposite, and overlaps each other, make the illustrative material that is placed in first extra play be difficult in use losing, be convenient to sort out and management.
With reference to Fig. 2 and shown in Figure 3, dedicated tool is described in detail.
In the process of producing valve bag, need a kind of dedicated tool, this dedicated tool is arranged on the capper, can cut out tearing notch 13 when valve bag seals.
This dedicated tool is selected copper tool for use, and a rib back of the body of its cutter hub 20 is as the knife edge, and this knife edge is provided with edge easy to tear, and according to actual needs, the quantity of edge easy to tear can increase with the increase of easy-torn line 14 quantity.This edge easy to tear is provided with male tool bit, and the number of male tool bit matches with the number of tearing notch 13, on the knife edge a plurality of male tool bit can be set.In this preferred embodiment, on the both sides of the knife edge, being symmetrically arranged with two pairs of male tool bit, is respectively first male tool bit 21 and second male tool bit 22.The height of first male tool bit 21 and second male tool bit 22 is 2mm, between distance be 3mm, the knife edge of copper tool and the thickness of male tool bit are 1mm, the thickness of the knife back is 15mm.
In the production process, at first hopper, barrel, the screw rod by inflation film manufacturing machine is sent to the PE raw material in the mould, under the temperature between 150 ℃～160 ℃, produce the film that has easy-torn line 13, clip chain 12 and potted line 12, the specification of this film is regulated by the blower fan and the electric eye of inflation film manufacturing machine.Then, film is passed through capper, at this moment, the temperature of capper copper tool is controlled between 240 ℃～260 ℃, and under this temperature, copper tool was depressed according to the time of setting, first male tool bit 21 of the edge easy to tear of copper tool and second male tool bit 22 just in time are pressed on the easy-torn line 14 of two bags 10, easily tear bag with what film was cut into certain specification, simultaneously, the position of easy-torn line 14 forms two tearing notches 13 on two sides of bag 10.By setting depressing the time of copper tool, can produce the valve bag of different size.In the whole process that valve bag is produced, inflation film manufacturing machine, capper, copper tool are worked in coordination, and make the production one-shot forming of valve bag, do not need other machining, thereby have reduced processing link, have reduced tooling cost, have guaranteed high rate of finished products.
