The specific embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Fig. 1 is the general structure schematic diagram of double-film bag making machine of the present invention, as shown in Figure 1, the used inner layer film of the present invention is the low order end that the tube film places machine, form with the volume film is fixed on the inflatable axle, the inflatable axle relocates on the adjustable shelf of the first discharging device a, adjustable shelf is provided with constant tension control system, reaches the photoelectricity automatic centering deviation-rectifying system of forming with fixed mount.The coating materials of inner layer film sends for blowing rubber draw rollers assembly by the blowing motor by the synchronous pulley transmission.Its speed control (fine setting) is finished by tension force pendulum roller thereafter.Tension force pendulum roller also can be adjusted the tension force of tube material by the adjustment of cylinder air pressure, is complementary with assurance and outer membrane tension force.The tube film enters mechanical measuring thickness device b through connecting gear, the coating materials of tube film is carried out thickness detect.Two volumes reload individual thickness difference are arranged when bonding because coating materials is in front and back, and measuring thickness device is exactly this thickness difference to be carried out amplified current handle finishing warning and picking and be coated with action.
With outer membrane is that the sheet film is positioned on the adjustable shelf of the second discharging device c with the inflatable axle equally, constant tension control system is arranged on the adjustable shelf equally, and system for automatically correcting, the coating materials of sheet film is sent to through connecting gear and overlaps the A of mechanism, joins with the tube film that comes from the first discharging frame a.(the big deflector roll that overlaps the A of mechanism can be done front and back adjustment up and down by swing arm), at this moment the tube film is last, and the sheet film is following.Two membranes enters folding forming device d together.
Folding forming device d mainly is made up of frame, deflector roll, moulding inner formword and fixture, big fine taper forming press-roller, cylindricality forming press-roller, pressing plate, carry-over pinch rolls system, jockey pulley, water conservancy diversion post forming parts etc.
Enter the below of moulding inner formword after inner membrance and adventitia are overlapping, adventitia is again by big fine taper forming press-roller, column type forming press-roller, pressing plate etc., inner membrance and moulding inner formword are wrapped in the inside, and wherein, it is different with thickness and different that the width of moulding inner formword is looked the bag width.Frictional resistance when reducing folding forming, the contact-making surface that supports moulding inner formword and film weight adopts row's deflector roll to realize.Here, the tubular size that requires adventitia to be converted into is consistent as far as possible with the tubular size that inner membrance is converted into, and the motion of coating materials in the folding forming process continuously carried out, and is used for safeguarding the stable of folded size.Its tractive force derives from one group of blowing draw-gear, mainly by the three phase electric machine, synchronous pulley of main transmission rubber roll, pressure roller and swing arm clamping cylinder and band gear reduction box, band etc. is formed synchronously, the power of main transmission rubber roll is that the three phase electric machine by the band gear reduction box provides by synchronous band.The hold-down roller of top provides pressure by cylinder.The supply gas pressure of adjusting cylinder just can change the traction frictional force of coating materials, thereby guarantees that coating materials normally moves.
Enter tension roller mechanism through folding coating materials by carry-over pinch rolls, the tension roller mechanism here is similar substantially to first, second tension force pendulum roller mechanism structure of inserting the device g of group, so the structure of mechanism is with reference to the slotting device g of group described later, its function is: (1) can adjust the coating materials tension force in this stage; (2) by guaranteeing that with current potential that the tension force swing arm links the speed of service of this stage coating materials speed of service and main body coating materials is consistent; What (3) become coating materials operates to intermittent duty continuously, and coating materials enters folding post forming device (summary) through the pendulum roller, enters centre joint sealing device e again.
Centre joint sealing device e is similar to general composite membrane Bag Making Machine.Promptly that the centre joint of external membrane carries out hot pressure at certain pressure, in the regular hour is firm with the boiling hot cutter that reaches uniform temperature via the heating of electric backing plate.(scalding cutter moves up and down) (the operation principle modular construction slightly), the intermitten service of coating materials is finished by the first carry-over pinch rolls f.
The carry-over pinch rolls of the first carry-over pinch rolls f are controlled by servomotor, and are accurate to guarantee its material drag length.(structure, principle are slightly)
Coating materials is promptly inserted the shaped device g of group through the core apparatus that the first carry-over pinch rolls f enters this machine.The purpose of this device is that overlapping two layered cylinder film is inserted the width of helping into qualified middle envelope and inserted group's degree of depth.
Insert in the making of group's bag at common composite membrane, general monofilm is realized with the sheet film.Slotting group will use intermediate die plate, for preventing that the intermediate die material is subjected to the frictional force effect and moves in slotting group process.Therefore will fix, when sheet stock was produced, intermediate die plate can be fixed in the inner membrance, and inserting group's moulding simultaneously is horizontal direction.Insert in group's moulding general monofilm garment bag, handbag and soft moulding, have plenty of and on folding tube film, carry out.Because its thickness is little, matter is soft, can charge into air in one section tube film, makes its distending, imposes on necessary typing, location outside, and is inserted into required shape.Its work generally is continuous, and direction is vertical.The coating materials of our bag is double-deck now, two layers the certain error of folding existence, and coating materials is thicker simultaneously, and bilayer thickness is generally between 0.2～0.3 or bigger.Material is harder, be PET or plastic-aluminum combined, paper is harder.Obviously that can not realize inserting group's moulding with the method for inflating.Because internal layer tube film is made of the method for general complex pocket, template has no idea to fix in the middle of it, also is to realize inserting group's moulding.
Purpose of the present invention will address this problem exactly, through discussing decision repeatedly interior cavity template has been made the special body of certain quality, and it vertically is placed on up and down between the material folding roller.Operation continuously from bottom to top when coating materials passes through it.Frictional resistance when the gravity of interior cavity template is a bit larger tham coating materials and inserts group like this, template just can not move up.Also imaginary inner formword be set.Two sides are pressed into roller, as long as the amount of being pressed into relative equilibrium can not waved about the side inner formword, for more insurance, the front and back of template are provided with 4 deflector rolls up and down respectively within it, like this, make inner formword keep plumbness on the one hand, also can prevent the play up and down of the trace of inner formword on the other hand.Certainly, if the quality of inner formword is too big, the power that then supports it also increases, coating materials by the time be subjected to its extruding to increase frictional force, be unfavorable for moulding; If quality is too little, the frictional force when inserting group's moulding can make progress away inner formword together, if with its deflector roll jam-packed of retaining, also can produce the resistance that is unfavorable for inserting group, thus inner formword can tame about ideal between the feed roller.
Since it is continuous inserting group's moulding, will guarantee its realization by a power so, therefore to there be a servomotor to drag the device of carry-over pinch rolls.Full automatic mechanical production from the coating materials to the bag simultaneously, it is inserted group's part and must cooperate and harmonious with other parts are organic.And be respectively middle envelope heat seal and horizontal sealing heat seal in the front and back of inserting group's moulding, coating materials here is intermittent movement.Therefore, must become coating materials intermittently → continuously → conversion intermittently.In unit interval simultaneously, the average speed of the first intermittent movement average speed and continuous motion must be identical with the average speed of second intermittent movement.This requirement here also must be met.
The present invention inserts the device g of group shown in Fig. 2,3,4,5, and end square steel 1, stull shelves 2, wallboard 3, right montant 16, left montant 20, crossbeam 64 etc. have been formed a framework, i.e. frame.Being used for the front and back device is being connected of centre joint sealing device e and traverse sealing device h.This installs the carrier of each functional part supporting (installation) that main also is.
First tension force pendulum roller mechanism is set on the right side of wallboard 3, is used for the intermittent movement of tube film when the centre joint involution is converted to continuous motion.The tube film enters first tension force pendulum roller mechanism through deflector roll, and first tension force pendulum roller mechanism comprises: cage is put on roller 4, by the little axle of side plate, compositions such as bearing block spacer.For reducing tube film fold, cage is put on roller 4 and is installed in the big swing arm 5, but the rotation of freedom and flexibility ground, the other end of big swing arm 5 is fastened on the arm shaft 6, and arm shaft 6 two ends are installed on the wallboard 3 by bearing again.The variation of coating materials length makes cage put on rod 4 and swings up and down, and also is fixed with little swing arm 81 in big swing arm 5, and it links by connector 80 and cylinder 79, and cylinder one end is installed on the wallboard 3 with bearing pin 78.If changing the air pressure of cylinder just can adjust the tension force of coating materials.
Simultaneously fix a fanning strip 9 in a side of big swing arm 5, it makes up near switch and switch fixed head and just can adjust the upper-lower position that cage is put on roller 4 with 2.The material drag speed of first carry-over pinch rolls is done to adjust in good time.Operation principle is as follows:
When Bag Making Machine carries out material drag with certain speed, big swing arm 5 swings up and down in certain scope, fanning strip 9 also swings up and down thereupon, if at this moment 2 are adjusted to all in the range comprehension of fanning strip 9 near switch, promptly 2 are not exposed its edge near switch when swinging up and down at the fan plate, and a rational side-play amount is arranged, and at this moment, the motor speed of the first carry-over pinch rolls f is invariable.
The dispensing speed that causes the first carry-over pinch rolls f when certain reason is during less than the setting speed of complete machine, because the accumulation coating materials shortens, the tension force cage is put on the roller 4 and is lifted, below one when just breaking away from blocking of fanning strip 9 (surmounting lower limb) near switch, just send signal instruction, force the first carry-over pinch rolls f to strengthen the discharging amount of coating materials.Cage is put on roller 4 and will be moved down like this, and fanning strip 9 shelters from 2 near switch again, reaches new balance blowing.
Otherwise cage is put on roller 4 and is moved down, and goes up and leaves blocking of fanning strip 9 near switch, and then the first carry-over pinch rolls f just reduces the discharging amount of coating materials.Cage is put on roller 4 and will be risen gradually and block near switch.Coating materials speed reaches balance again.
Coating materials method of operation behind first tension force pendulum roller mechanism promptly is transformed into continuous motion by intermittent movement.
