Description

Closed valve port bag maker

Technical field

The present invention relates to packaging bag manufacturing equipment field, particularly a kind of closed valve port bag maker.

Background technology

At present, the valve port paper bag is widely used in the packing of powder body material, and particularly the valve port paper bag is after can, and outward appearance is square-folded, is all extremely convenient and safety of pile or transportation.But along with powder body material granular size granular more and more, the valve port paper bag is because of the deficiency on the original structure causes leaking powder, problem such as make moist has displayed.As depicted in figs. 1 and 2; The paper of two bottoms 32 of valve port paper bag 31 is converted into the shape like Fig. 1, and smears vertical glue 34 and bond with transverse glue 35 and form, and can find out from the corner 38 of folding line 37; Though vertical glue 34 has been smeared in the inside of paper 33; But still can not be bonded together fully, always can stay space 39, this space 39 is with being communicated with in the valve port paper bag body.This is owing to paper flexible and elasticity, and particularly when multi-layered paper was folding together, elasticity also had very strong synergistic effect.When material when valve port 36 is filled into the valve port paper bag 31, partial material can leak out from the corner 38 of folding line 37, causes material from leakage, causes the packing failure.

Result of the above problems is before last moulding bonding, increases an interior finishing strips in two bottoms 32 of valve port paper bag 31, and all boning the space with the mode on plane overrides; As shown in Figure 3, after two bottoms 32 of valve port paper bag 31 are folded into the shape like Fig. 3, before bottom adhesive; Smear shaped as frame glue 41 earlier; Entirely be bonded in the promptly inner strong bar 40 of as smooth paper on the frame type glue 41 then, in so just covering folding line 37, stopped up material from the inner path that leads to corner 38 of sack; Folded, glued bottom 32 traditionally then; Because having between the smooth bonding paper of smooth bonding does not have the space, so reached complete airtight effect, so just can make closed valve port paper bag.But technological difficulties are how on automatic assembly line, to realize the continuous high speed production of above-mentioned closed valve port paper bag.

Summary of the invention

Technical problem to be solved by this invention provides a kind of closed valve port bag maker, and it can produce the closed valve port paper bag of inner strong bar fast.

For solveing the technical problem, the invention provides a kind of closed valve port bag maker, it is characterized in that; It comprises paper frame, tensioning pendulum roller, cutter grooved roller, cutting roller, crosses paper bowl, first carry-over pinch rolls, second carry-over pinch rolls, first pressure roller, second pressure roller, pulls apart roller, nip rolls, paster roller, base, footstock, holding paper cutter, top paper cutter; The paper frame is installed between base and footstock, and a side of paper frame is equipped with tensioning pendulum roller, and a side of putting roller in tensioning is equipped with cutter grooved roller and cutting roller; Side at cutting roller was equipped with paper bowl; A side of crossing paper bowl is equipped with first carry-over pinch rolls and second carry-over pinch rolls, and a side of second carry-over pinch rolls is equipped with first pressure roller and second pressure roller, and a side of second pressure roller is equipped with pulls apart roller; Side pulling apart roller is equipped with nip rolls; The paster roller that is mounted in its next door with the nip rolls cooperating is equipped with top paper cutter on the nip rolls, the holding paper cutter is installed on the paster roller.

Positive progressive effect of the present invention is: closed valve port bag maker of the present invention can be produced the closed valve port paper bag of inner strong bar fast.

The specific embodiment

Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the present invention that intactly explains.

Like Fig. 4 and shown in Figure 5; Closed valve port bag maker of the present invention comprises paper frame 1, tensioning pendulum roller 4, cutter grooved roller 5, cutting roller 6, cross paper bowl 7, first carry-over pinch rolls 8, second carry-over pinch rolls 9, first pressure roller 13, second pressure roller 14, pull apart roller 16, nip rolls 17, paster roller 18, base 21, footstock 22, holding paper cutter 23, top paper cutter 24; Between base 21 and footstock 22, paper frame 1 is installed; Paper roll 2 is housed on paper frame 1, and the direction of motion of the paper 11 that paper roll 2 is emitted is according to the direction of arrow 3.One side of paper frame 1 is equipped with tensioning pendulum roller 4; Side at tensioning pendulum roller 4 is equipped with cutter grooved roller 5 and cutting roller 6; Jagged 12 on the blade of cutting roller 6, in a side of cutting roller 6 paper bowl 7 was installed, first carry-over pinch rolls 8 and second carry-over pinch rolls 9 are installed after crossing paper bowl 7.One side of second carry-over pinch rolls 9 is equipped with first pressure roller 13 and second pressure roller 14.Continuation also is equipped with a pair of roller 16 of pulling apart along paper 11 directions of motion; Promptly a side of second pressure roller 14 is equipped with and pulls apart roller 16; Side pulling apart roller 16 is equipped with nip rolls 17; The paster roller 18 that is mounted in its next door with nip rolls 17 cooperatings is equipped with top paper cutter 24 on the nip rolls 17, holding paper cutter 23 is installed on the paster roller 18.

Earlier the mode of paper 11 according to Fig. 4 is through in each roller mechanism, under the traction of motor power, 1 rotation of paper frame; Driving paper roll 2 rotations, paper 11 is unreeled out, and tensioning pendulum roller 4 is pressed and held up on paper 11; Regulating the tension force of paper 11, paper passes between cutter grooved roller 5 and cutting roller 6, and cutter groove rod 5 is cooperating with cutting roller 6 and rotates; Cutter groove rod 5 supports are lived paper, and the cutting knife cutting paper on the cutting roller 6 is because jagged 12 existence; So the mode of cutting is exactly that void is cut; Promptly whenever also in succession at a distance from ten centimetres of silks of just reserving one about half millimeter in incision, cutting back paper 11 does not break off fully, and the intensity of the silk of ining succession can not be broken off when paper 11 is normally drawn.Paper 11 passed paper bowl 7, first carry-over pinch rolls 8 and second carry-over pinch rolls 9, got between first pressure roller 13 and second pressure roller 14, and this tightly embraces pressure roller and clamps paper 11, and paper 11 to front haulage; When paper gets into when pulling apart roller 16, because this is greater than the rotating speed of first pressure roller 13 and second pressure roller 14 to the rotating speed of pulling apart roller 16, so; Just cut 15 places, position in void by the empty paper of cutting and pulled apart half millimeter that had before stayed silk, paper continues to get between nip rolls 17 and the paster roller 18, and the top paper cutter 24 on the nip rolls 17 heads into paper in the holding paper cutter 23; When the two continues rotation; Holding paper cutter 23 has just stepped up paper 11, and when the holding paper cutter 23 on the paster roller rotated to sack 19 position contacting, holding paper cutter 23 discharged paper; Just paper has been attached on the tram as shown in Figure 4, sack bottom; This paper is exactly interior finishing strips 20, interior finishing strips 20 bonds to sack 19 to mode with the plane, stopped up might be after can to the passage of external leakage.

Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited appended claims.
