66,67 at the two ends of a framework 72, and the middle part of framework is connected on the bracing frame 71 by spring 70.Two pressure rollers of bonded assembly on the framework, one is saddle type limit roller, one is straight roll.

The coated paper envelope sticking mouth of bag machine of convenient folding mouth, full electrical-mechanical control circuit is controlled three Daepori three-way motors, and one is main driving motor, and one is the nip rolls motor of check pipe builder, and one is the appendage vacuum pump motor.Three motors do not need synchronously.Wherein main driving motor and vaccum pump motor turn round continuously, and the nip rolls motor is a timing working.

The working process of sticking mouth of bag machine is: at first place on the work top of machine with the bag tube 11 that manually will make no side wall, send into conveying mechanism (Fig. 2) one by one, and make its location, at this moment, the two ends of bag tube all are sandwiched between chain pin plate and the flat belt, and between two side rails 28, and be held with load-transfer device and at the uniform velocity advance.According to the specification requirement of paper bag, conveying mechanism can be adjusted transverse width and guide clearance.

When paper bag 11 entered out a mechanism (Fig. 4,5), upper and lower two fronts of bag tube were held by upper and lower suction nozzle 30, and owing to affecting of conveying mechanism, the bag tube moves on, and the bag tube is opened, and formed a blade shaped space.Layering this moment head enters leaf space, and suction nozzle then automatically resets later at bag tube warp.Suction nozzle remains the air draught state, can enter work at any time, and it sucks by the joint door and regulates.When the layering head enters the bag tube, at first support to guide rail 28 at the bottom of the front side by 35 bag tubes of layering head rotor, tentatively extrude triangular shaped.A layering slide 31 presses down to guide rail in the manipulation of cam mechanism then, because the convex surface mutual action in the convex surface of rotor rack 34 and the support claw 32, two support claw ends are open, again because the directional tagging of layering head, the bag tube is strutted up and down, at the bottom of forming side, get ready.

When at the bottom of paper bag 11 approaching sides during builder (Fig. 6,7), contact with recessed plate washer 37 earlier at the bottom of the triangle side that begins to take shape, in the location, the symmetry that is shaped at the bottom of the control side, then by the suction glue on the side bottom press roll 38 brush 36 with gluing at the bottom of the side, to get step sticking dress check pipe ready.Because after forming at the bottom of the front side, two positive ends of sack, are by a minute disassemble, so also form a triangle knuckle at the bottom of the rear side of sack.Through bag tube pressurized between side bottom press roll and the guide rail, formed at the bottom of former and later two sides at the bag end.The side bottom press roll of equipment both sides is connected with main gear by bevel gear, rotates synchronously with conveying mechanism.Can pressurize when making pressure roller have paper bag to pass through, no paper bag by the time guide rail is not produced friction, universal coupling is housed on pressure roller shaft, and adjusts the gap that limiting stopper 41 keeps having between pressure rollers and guide rail one deck paper thickness.

When paper bag 11 enters check pipe builder (Fig. 8), place the check pipe builder in guide rail 28 outsides, its paper tape is moved by the nip rolls tractive that separate electrical motor drives.When paper tape process shaping deflector roll 45 and pedal 46, paper tape is converted into a knuckle, central authorities' 1/2 width of paper tape is pressed by pedal and is stepped on, and each width of 1/4 of paper tape both sides knee 47 that then is formed pushes away the both sides that are converted into doubling, the flat tube of paper tape through being pressed into behind the nip rolls gradually.Because the check pipe is sheared and tubulature is an intermitten, therefore the sheetmetal 21 that is loaded on every group of chain pin plate 23 front sides through being contained on the frame near switch 24 time, send actuating signal, the drive magnetic adhesive of the pushing hands 50 in commander's check pipe mechanism, do the ejector sleeve action, front side at the bottom of the check pipe is pushed into bag exactly, This move is instantaneous carrying out.After the release, the nip rolls motor rotates, treat that paper tube enters paper storehouse in the pushing hands after, make the motor stall by photoelectric circuit control, again with 49 work of time delay circuit control scissors, thereby cut off the check pipe.

Then paper bag enters builder of the positive end (Figure 10,11).Be positioned at the astragal builder (Fig. 9) in the builder outside, the positive end, when paper bag moves, make astragal.Joint close paper is folded in half into astragal through the paper folding device 52 of curved surface turnover type in the astragal mechanism, and tearing mouthful wire clamp open among astragal, because tearing a mouthful line open has certain tension force, with process gluing sheave 58 gluings,, become integral body so can carefully and neatly stick together with astragal.When paper bag is traveling in the relative upper and lower frid of builder of the positive end 60,61 initial segments, under the mutual action of frid and pressure roller 64, the upper and lower end of paper bag, inwardly turned down 90 °, and the check pipe on sticking at the bottom of the front side fastened, gluer 62 upper surface at the positive end under paper bag that is located at down subsequently top, frid 61 stage casings is coated with glue, when paper bag advances to upper and lower frid latter end, through the mutual action of frid curved surface and pedal 65, the upper and lower two positive ends of paper bag, are again to 90 ° of center turnovers.This moment because of the following positive end be shaped wrong after in the last positive end, so outside the following positive end takes at the bottom of the Yu Shangzheng.After this, place upper and lower frid four sides gluer 53 afterwards, the outside, the last positive end that will from crack, pass through, the upper and lower both sides of astragal and the inboard gluing at the following positive end enter the reinforcing building mortion then.Be positioned at the builder of the positive end of conveying mechanism both sides, except that pressure roller 64 by bevel gear with main gear is connected, all the other are passive type.

Reinforce builder (Fig. 2) when paper bag 11 enters, at first introduced the additional base stock band that was coated with glue, and quilt pressure roller 69 pressings then.In order to strengthen bonding firmness, behind pressure roller, also be provided with the multiple pressure roller of swing elasticity of a pressure self-adjusting formula, can carry out pressing to each position of sack respectively, reinforcing builder in the conveying mechanism both sides, pressure roller is connected with main gear by bevel gear, and multiple pressure roller is a passive type.

Paper bag enters cutting mechanism (Figure 13,14,15) at last.Its effect is that the continuous additional end and astragal are cut off, and the paper bag that is chained together is divided into single paper bag.When needs are sheared, cam 77 drives rocking bar 76, thereby promoting connecting rod 75 lifts scissors crane 83, reach control position, when rising with the scissors crane, the outer inclined-plane slideway of cutting on the arm 80 86 is promoted by outer projection 87, makes the fixedly cutting edge of cutting on arm drive activity cutting edge 82 and the scissors crane 81 tangent, just cuts off coupling link.When rocking bar slipped over the cam peak dot, then the scissors crane descended, and cut the interior inclined-plane of arm slideway 85 simultaneously and contacted with interior projection 84, and movable cutting edge is opened.The adjustment of suit overlaps 78 on the rocking bar, can be used to adjust the time and the stroke of action.Cam then rotates synchronously with main gear.
