The specific embodiment
Shown in Fig. 1～3, the weak welding line welding mechanism of infusion bag of the present utility model, comprise weak welding template 15, heating plate 7, heat seal cylinder 11, backing plate 4, bag air inlet patrix 17, bag air inlet counterdie 18 and wallboard 1, heat seal cylinder 11 is fixed on the wallboard 1 by installing plate 14, its piston rod links to each other with heating plate 7 by pressing plate 9, be connected by adapter sleeve 10 between pressing plate 9 and the piston rod, be provided with heat insulation post 8 between heating plate 7 and the pressing plate 9, weak welding template 15 is fitted with heating plate 7, backing plate 4 is relatively arranged on weak welding template 15 belows, and by gripper shoe 3 supports of being fixed on the base plate 2, base plate 2 is fixed on the wallboard 1, and a bag film 6 places on the backing plate 4.Weak welding template 15 is finished the thermal weld to weak welding line in the infusion bag, because weak weldering welding requires very high to temperature and pressure, so the stepless adjustable temperature controller of constant temperature is adopted in the temperature control to heating plate 7, air pressure to heat seal cylinder 11 adopts the accurate voltage regulating valve to realize, guarantees that the weld strength of weak welded seam reaches perfect condition.Bag air inlet patrix 17 is installed in the rear end of weak welding template 15, fits with weak welding template 15, and bag air inlet counterdie 18 is fixed on the backing plate 4, and is corresponding with bag air inlet patrix 17 positions, and during work, bag air inlet counterdie 18 places among the two membranes of bag film 6.The effect of bag air inlet patrix 17 and bag air inlet counterdie 18 is be shaped at the rear portion of bag film 6 bag air inlets 23 shown in Fig. 3,4, when being beneficial to adorn the solid coyote hole and need inflating, can be from then on mouthful gas be charged in the solid coyote hole.On bag air inlet counterdie 18, offer a cooling duct 181 (see figure 5)s, this passage is connected with the cooling water interface by pipeline, can cool off bag air inlet counterdie 18 by cooling water, in order to avoid bag film 6 sticks together because of high temperature and bag air inlet counterdie 18.
At bag film 6 four jiaos into and out of the position, be provided with bag mould 21, main effect is when weak welding that mould is tight, makes the film can be not wrinkling, guarantees the effect of welding.As shown in Figure 1, 2, on wallboard 1, four press mold cylinder installing racks 22 before and after being connected with by the press mold cylinder support plate 20 that is positioned at its both sides are equiped with press mold cylinder 19 on the press mold cylinder installing rack 22, and installing bag mould 21 on the piston rod of press mold cylinder 19.
As shown in Figure 1, 2, 3, respectively be provided with one in the rear end of the front end of bag film 6 outlet and import and open lamina membranacea 5, be installed on the press mold cylinder support plate 20 on the wallboard 1 and be equiped with out lamina membranacea support plate 16, open on the lamina membranacea support plate 16 installing and open lamina membranacea 5 what film separated; Its effect is that the front portion of film and rear portion are separated, and mainly is in order to weaken the bonding force between the two membranes, to be beneficial to the back operation two membranes is separated; Front portion as film will be put into interface between the two membranes before shaping, and the rear portion of film needs solid coyote hole and perfusion mouth inhaled to open in solids chamber inflation sealed station to be beneficial to air (or nitrogen) to enter solid medicine indoor.
As shown in Figure 1, 2, in this example, heat seal cylinder 11 be about two be symmetrical arranged, between two heat seal cylinders 11, also be provided with fairlead 12 and the lead 13 that places in the fairlead 12, fairlead 12 is installed on the installing plate 14 that is fixed on the wallboard 1, and lead 13 links to each other with pressing plate 9.Play the guiding role when a welding template 15 and a bag air inlet patrix 17 move up and down a little less than 13 pairs of the leads, guarantee the invariant position of each work.
The course of work of the present utility model is: when bag film 6 is placed in the utility model, bag mould 21 is flat fixing with mould under the effect of press mold cylinder 19, weak simultaneously welding lamina membranacea 15 and bag air inlet patrix 17 will place the bag film 6 on the backing plate 4 to compress downwards under the effect of heat seal cylinder 11, because weak welding template 15 has certain temperature, so under certain pressure, weak welding template 15 can be with the two membranes hot weld together.Because bag air inlet counterdie 18 is in the centre of two membranes, so bag air inlet patrix 17 upper strata shaping output air inlet 23 during with 18 pressings of bag air inlet counterdie to film.When weak welding template 15 and bag air inlet patrix after 17 pressurize regular hours, 11 withdrawals of heat seal cylinder, a then weak welding template 15 and a bag air inlet patrix 17 also upwards leave backing plate 4 and get back to original position.Press mold cylinder 19 is decontroled film simultaneously, finishes once weak welding job.Simultaneously open lamina membranacea 5 and respectively front portion and rear portion through the film of this mechanism separate for two, the bonding force with between the minimizing separate section two membranes is beneficial to the back operation two membranes is separated.
The quantity of an embossed bag of the utility model can be two or three or four or six.
Shown in Fig. 6,7, the structural representation of two kinds of two chambers bags processing for the utility model; It is two chambers bag of being made up of liquid coyote hole 61 and solid coyote hole 62, is separated by the weak welded seam 63 of the utility model processing between two Room, and solid coyote hole 62 is reserved marsupial air inlets 23 at this moment.
The utility model can be installed on various Bag Making Machines or the bag-making loading production line, and processing can be with the multicell infusion bag of fashionable dress liquid medicine and solid medicine.Fig. 8 is placed on the Bag Making Machine of the two chambers of single port pipe bag as an application example of the present utility model, can process bag as shown in Figure 6.The utility model can place between lettering assembly 25 and the membrane assembly 26, and promptly the utility model is to be contained in after the lettering assembly 25, and weak weldering was carried out before bag is shaped; Also lettering assembly 25 and the utility model position can be exchanged, promptly the utility model places between film feeding assembly 27 and the lettering assembly 25, a little less than be welded in lettering and carry out before.The utility model places between lettering assembly 25 and the membrane assembly 26 in this example, is bag forming assembly 28, joint weld assembly 29, bag separation assembly 30 and bag conveying assembly 31 afterwards successively.
Fig. 9 is placed on the Bag Making Machine of double flexible pipe double chamber bag as Another Application example of the present utility model, can process bag as shown in Figure 7.The utility model can place between lettering assembly 25 and the membrane assembly 26, and promptly the utility model is to be contained in after the lettering assembly 25, and weak weldering was carried out before bag is shaped; Also lettering assembly 25 and the utility model position can be exchanged, promptly the utility model places between film feeding assembly 27 and the lettering assembly 25, a little less than be welded in lettering and carry out before.The utility model places between lettering assembly 25 and the membrane assembly 26 in this example.
