What be used for big soft infusion bag production line does not shut down automatic cover replacing device
Technical field
The utility model relates to the pharmaceutical machine apparatus field, relates in particular to the film device that changes that big soft infusion bag production line uses.
Background technology
The used standard film material length of big soft infusion bag production line is 500 meters, and by 4200 bags of/hour calculating of speed of general soft bag product line, the production time of a volume standard film is about 54 minutes, promptly just needs with renewing film after 54 minutes.In the middle of existing technology, because original film material is lax, can not continue to produce when changing film, need shut down and change film, original film material after being connected, can be continued the film material production with newly changing.General actuator's the film time of changing is about 3 minutes, owing to there is stopping process, makes Production Line efficient reduce, and will produce one group of useless bag when shutting down simultaneously, causes waste.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provide a kind of simple and compact for structure, with low cost, easy for installation, production efficiency is high, can realize not shutting down change film be used for big soft infusion bag production line do not shut down automatic cover replacing device.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of be used for big soft infusion bag production line do not shut down automatic cover replacing device; it is characterized in that: comprise press mold cylinder, cylinder adapter plate and driven unit; described press mold cylinder is fixed in by bolster on the bottom of cylinder adapter plate, and the top of described cylinder adapter plate links to each other with the external part of driven unit.
Use later-model further improvement as this:
Described cylinder adapter plate is provided with the governing plunger that is used for adjusting press mold cylinder rotating torque.
Described bolster is fixed on the cylinder adapter plate and by connecting key by sleeve and links to each other with the press mold cylinder, and an end of described bolster links to each other with the mouth of Rolling motor.
Described driven unit is cylinder assembly or servomotor.
Compared with prior art; advantage of the present utility model is: what the utility model was used for big soft infusion bag production line does not shut down automatic cover replacing device; simple and compact for structure, with low cost, easy for installation, production efficiency is high; can when changing film, provide constant tension force for original film material; make that manufacturing line can continue to produce; change film thereby realized not shutting down, improved production efficiency, reduced rejection number.

The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
Embodiment 1: as Fig. 1, Fig. 2, Fig. 4, Fig. 5 and shown in Figure 6; what the utility model was used for big soft infusion bag production line does not shut down automatic cover replacing device; comprise press mold cylinder 1, cylinder adapter plate 5 and driven unit; press mold cylinder 1 is fixed on the bottom of cylinder adapter plate 5 by bolster 2, bearing 3, and the top of cylinder adapter plate 5 links to each other with the external part of driven unit.The end of bolster 2 is provided with circlip 4, also is provided with the governing plunger 6 that is used for adjusting press mold cylinder 1 rotating torque on the cylinder adapter plate 5.Among this embodiment, driven unit is a cylinder assembly, and cylinder assembly comprises actuating cylinder 8 and cylinder mounting plate 9, and the fixed end of actuating cylinder 8 is connected on the cylinder mounting plate 9, and the external part of actuating cylinder 8 links to each other with cylinder adapter plate 5 by middle connecting plate 7.In this embodiment, during work (when film material 17 runs low the need replacing), actuating cylinder 8 moves downward, and press mold cylinder 1 contacts with film material 17 and film material 17 is compressed, as shown in Figure 6.Governing plunger 6 is given press mold cylinder 1 certain pressure, resisting moment when forming 1 rotation of press mold cylinder, freely rotating of restriction press mold cylinder 1, when film material 17 tension force arrive resisting moment when to a certain degree can overcome press mold cylinder 1 and rotating, press mold cylinder 1 rotates, film material 17 advances, thereby guarantees the constant of film material 17 tension force, satisfies the requirement that continues production.During this period, manually will go into machine on the new film material 17, link to each other with original film material 17.Actuating cylinder 8 upward movements then, press mold cylinder 1 separates with film material 17, finishes a working cycle, prepares to enter to change film next time.
Embodiment 2: as shown in Figure 3, in another embodiment, bolster 2 is fixed on the cylinder adapter plate 5 and by connecting key 11 by sleeve 10 and links to each other with press mold cylinder 1, and an end of bolster 2 links to each other with the mouth of Rolling motor 13.Rolling motor 13 is fixed on the motor mounting plate 12.In this embodiment, during work (when film material 17 runs low the need replacing), actuating cylinder 8 moves downward, and press mold cylinder 1 contacts with film material 17 and film material 17 is compressed, as shown in Figure 3.Rolling motor 13 work drives press mold cylinder 1 and rotates, and the speed that press mold cylinder 1 rotates is by Rolling motor 13 controls, and consistent with the film material 17 required speed of advancing, and satisfies and continues the requirement of producing.During this period, manually will go into machine on the new film material 17, link to each other with original film material 17.Actuating cylinder 8 upward movements then, press mold cylinder 1 separates with film material 17, finishes a working cycle, prepares to enter to change film next time.
Embodiment 3: as shown in Figure 7 and Figure 8, driven unit is a power motor 16, and this power motor 16 adopts servomotor, and middle connecting plate 7 links to each other with power motor 16 by drum driven plate 15, and power motor 16 is fixed on the motor mounting plate 14.In this embodiment, during work (when film material 17 runs low when need changing), power motor 16 work drive drum driven plate 15 and rotate, and make press mold cylinder 1 contact with film material 17 and film material 17 is compressed, as shown in Figure 8.Governing plunger 6 is given press mold cylinder 1 certain pressure, resisting moment when forming 1 rotation of press mold cylinder, freely rotating of restriction press mold cylinder 1, when film material 17 tension force arrive resisting moment when to a certain degree can overcome press mold cylinder 1 and rotating, press mold cylinder 1 rotates, film material 17 advances, thereby guarantees the constant of film material 17 tension force, satisfies the requirement that continues production.During this period, manually will go into machine on the new film material 17, link to each other with original film material 17.Power motor 16 backward rotation will be carried on the press mold cylinder 1 then, separate with film material 17, finish a working cycle, prepare to enter to change film next time.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
