Background technology
Present empty hard capsule uses more and more extensive at drug and food packaging field.Hollow enteric hard capsule can not melt at stomach and melt in intestines, and the medicine food be filled in hollow enteric hard capsule is only absorbed by the body utilization after intestines disintegration.Plain hollow hard shell capsules needs once to dip in gum forming, and enteric hard capsule needs secondary or repeatedly dips in gum forming.Along with people's medical living level improves constantly, enteric hard capsule uses more and more.Existing hollow enteric hard capsule manufactures device, the following several method of many employings or device:
1, adopt semi-automatic hollow hard shell capsules production line to dip in gum forming several times, such method efficiency low production quality is restive, because this empty hard capsule production line automation degree is low, user of service is too much, and production link is too loaded down with trivial details.
2, after in before adopting the Full-automatic hollow hard capsule production line of common form to divide, a small amount of lath of many parts is multiple batches of dips in glue, namely anterior parting bar (being generally 5 to 9) be integrated into one by one a template die bar dip in glue after (now can form plain hollow hard shell capsules), be pooled to 4 times of mould bars to this quantity again through conveying be transported to production line posterior part after drying and be divided into veneer mould bar again and repeatedly dip in glue, finally form qualified enteric hard capsule.Such device fabrication is complicated, controls difficulty, and production efficiency is low, and production cost is high.
3, the glue dipping machine disk lifting mechanism structure of existing Full-automatic hollow hard capsule production line generally completes by mechanical mechanisms such as rack-and-pinion, adjustment difficulty, also has people's servo-actuating device, but connects with opening elongated hole thin plate between part, connect rigidity poor, unstable when equipment runs.
Summary of the invention
The present invention aims to provide a kind of servo and dips in adhesive dispenser, and low with the automaticity solving prior art existence, user of service is too much, and production link is too loaded down with trivial details; And device fabrication is complicated, control difficulty, production efficiency is low, the problem that production cost is high.
Technical scheme of the present invention is: a kind of servo dips in adhesive dispenser, comprise once dip in glue assembly, secondary dips in glue assembly and for the upper pipeline of transfer die bar between and lower pipeline, it is characterized in that, described secondary dips in glue assembly and comprises frame, crane, mould bar pallet, pallet upset motor, crane elevating mechanism and lower propulsive mechanism, crane is connected in frame by guide rail longitudinal sliding motion, and crane elevating mechanism is housed between this frame and crane; Pallet upset motor is arranged on crane both sides, and the output shaft of pallet upset motor is connected with the bottom of the mould bar pallet be arranged in crane; Lower propulsive mechanism is provided with above mould bar pallet; Glue groove is provided with in the below of crane.
Advantage of the present invention is: anterior veneer mould bar makes it be elevated by servo-control system and freely overturn to carry out a servo and dip in glue, and once dip in the overall SERVO CONTROL in rear portion that at least four group mould bar dryings after glue are transported to production line and dip in glue (no longer veneer dips in glue), improve production efficiency; Dip in glue even, steady quality, improves product quality; Structure is simple, reliable, reduces production cost.

The course of work of the present invention is:
1, once dip in glue: when work starts, once dip in glue assembly A dip in glue disk 6 each five to the nine mould bars 8 of the static wait of initial position enter successively to dip in glue disk 6 draw-in groove in form one group of mould bar, disk lifting mechanism works, slide on straight optical axis 2 under being driven by the nut screw structure be fixed on slide block 3 and realize rising or declining, in the process declined, realizing dipping in glue disk 6 by rotating servo motor 11 by planetary reducer 10 drives one group of mould bar to rotate to an angle by manufacturing technique requirent together, realize the whole plate of mould bar 8 dip in glue and keep that to dip in glue thickness even, after rising arrives assigned address (being driven by disk lifting mechanism), by side push mechanism 37, one group of mould bar 8 is entered upper pipeline 31 from dipping in thruster glue disk 6, dip in glue disk 6 to return initial position and wait for next group mould bar 8, repeat said process repeatedly (as four times), be proposed four groups of mould bars 8 to be like this arranged in a row, arrow P direction in mould bar 8(Fig. 3 is arranged by one again by propelling movement position (electric cylinder 36 or screw-nut structure drive pushing ram 35)) be advanced on upper pipeline 31, be transported to secondary and dip in glue assembly B.
2, secondary dips in glue: the mould bar pallet 28 that secondary dips in glue assembly B is caught pushing through the row's mould bar 8 come from upper pipeline 31, by right lift servo motor by elevating screw 22, lifting line slideway 15 drags side plate 21 and declines, cylinder 32 pulls slide block 33 to be fixed on mould bar pallet 28 by pressure strip 34 by row's mould bar 8 simultaneously, pallet upset motor 26 is with dynamic model bar pallet 28 to overturn 180 °, one row's mould bar 8 is slowly immersed in the glue of body glue groove 13 and cap glue groove 14, after stopping certain hour, mould bar 8 is slowly promoted, then mould bar pallet 28 flips an angle the unnecessary glue removed on mould bar 8, rise to again and the propelling movement position of lower pipeline 30 1 levels, servomotor 16 is advanced will again to dip in a row four groups of mould bar 8 launch mode bar pallets 28 after glue on lower pipeline 30 by advancing ball screw 19 and advancing line slideway 20 to drag pushing ram 18.
The present invention makes anterior Dan Zumo bar make it be elevated by servo-control system and freely overturns to carry out a servo and dip in glue, and once dip at least four groups after glue (at least 4 times to above glue-dipping mechanism once dip in rubber moulding number) mould bar drying and be transported to production line postmedian and carry out secondary simultaneously and dip in glue, compared with dipping in glue with single secondary organized, production efficiency improves several times, overcomes the deficiency that prior art production efficiency is low.
