The working principle of the pre- filling apparatus of the syringe of the utility model is as follows:

As shown in figure 3, cork is in vibrating disk (not shown), (production firm: it is limited that prompt automation equipment science and technology is interrogated in Kunshan vibration Company) in screened, by concussion screening after cork cylinder it is face-up, circular cone is face-down, into a plug slot road 212, then It is transported to right above circular hole 217, is blocked by the plug baffle 216.

It drives two cams 225 to circle by retarder 229, the squeezing needle 224 for squeezing upper plate 223 is driven to make vertically It moves downward, as shown in Fig. 4 A~4D and Fig. 5, the cork being placed in right above circular hole 217 is squeezed the pressure effect of needle 224, Across circular hole 217, and fall in the syringe immediately below entering.As shown in Fig. 6 A~6B, in the process, cylinder 237 drives gear The U-shaped baffle 233 of cylinder unit 23 makees movement in horizontal direction, keeps off the engagement pad 234 of 233 inside of U-shaped baffle on cylinder unit 23 The lid of arc-shaped pad slot 235 closes the syringe on carrier chain 10, falls to prevent syringe.

As shown in figure 5, at this point, squeezing needle 224 continues to exert a force, by the crowded intracavity bottom stabbed into syringe of cork.

It jumps a queue completion, squeezing needle 224, with movement upward vertical movement, is detached from syringe by retarder 229.U-shaped baffle 233 is made Horizontal outward movement, far from the syringe on carrier chain 10.

Carrier chain 10 moves forward.

As shown in fig. 7, the movement of carrier chain 10 stops when the syringe that carrier chain 10 transports moves to liquid filling 32 surface of component Only.

As shown in Fig. 8~9, retarder 315 drives pitch wheel 316, to drive 31 top of transfusion unit Ceramic rod 3114 is by the twisting with movement clockwise or counterclockwise, when the drug slot 3115 of the outer surface of ceramic rod 3114 is twisted to right When the medical fluid entrance 3112 of quasi- hollow bar set 3111, the hollow bar set 3111 in 3114 outside of ceramic rod is driven by servo motor 319 Make vertical displacement movement, extracts medical fluid to certain dosage.After the completion of medical fluid extracts, ceramic rod 3114 is twisted again to its outer surface Drug slot 3115 be aligned hollow bar set 3111 medicine liquid outlet 3113, at this time medical fluid by transfusion unit 31 flow into liquid filling unit 32.

As shown in Figure 10, after medical fluid flows into liquid filling unit 32, two cams 3223 drive liquid filling component 32 to do vertically upward Movement moves stopping after contacting syringe lower end, and liquid filling component 32 pours into medical fluid in syringe.

As shown in Figure 12 A~12B, in the process, cylinder 3333 drives U-shaped sideboard 3331 to move inward as level, interior After the lid of arc-shaped pad slot 3335 of the engagement pad 3334 of side closes the syringe on carrier chain 10, landing when preventing syringe liquid filling.U-shaped sideboard Horizontal pressure foot 3332, the compressible top surface in syringe in 3332 lower surface of horizontal pressure foot, for preventing syringe are fixed on 3331 It is jumped out in pouring process in vertical direction.

As shown in fig. 7, liquid filling component 32 moves vertically after the completion of liquid filling, far from syringe lower end, U-shaped sideboard 3331 makees water The flat syringe being moved outwardly away from carrier chain 10.

Carrier chain 10 moves forward.

As shown in figure 13, when the syringe that carrier chain 10 transports moves to U-shaped 4423 opposite of baffle-wall, the movement of carrier chain 10 stops Only.

As shown in Figure 14 A~14C, cover is in vibrating disk (not shown) (production firm: Kunshan Zhen Xunjie automation equipment section Skill Co., Ltd) in screened, upward, appearance is face-down for the inner surface of cover after screening, into set cover base 411 and be connected to Cover slot road 4113, be then transported in the circular through hole 4112 for setting the lug boss 4111 of 411 side of cover base, and by cover Part 412 is held.

Then, as shown in figure 15, stamp lid stick 424 makees vertical downward movement, will be placed in the circular through hole of lug boss 4111 Cover stamp on 4112 drops down onto the headkerchief 4314 of the spiral cover unit 43 as shown in Figure 16 A~16C.

As shown in Figure 17 A~17C, in the process, horizontal air cylinder 4322 drives the U-shaped baffle-wall 4423 of resistance cylinder part 441 to make Level moves inward, and the lid of arc-shaped pad slot 4425 of the blocky engagement pad 4424 of U-shaped 4423 inside of baffle-wall closes the needle on carrier chain 10 After cylinder, prevent syringe from sliding.A pressure cylinder piece 441 is fixed on U-shaped baffle-wall 4423,441 lower surface of pressure cylinder piece is compressible in syringe Top surface, fallen for preventing syringe to be squeezed during spiral cover in vertical direction.

As shown in figure 13, rotary cover assembly 431 makees upward vertical movement by the driving of lifting cylinder 4324, until headkerchief 4314 contacts Syringe lower end, movement stop, and then drive the gear 4312 in rotary cover assembly 431 by motor 4313, cover is tightened.

Cover tightens rear rotary cover assembly 431 and makees vertical downward movement, leaves syringe lower end.U-shaped baffle-wall 4423 makees horizontal direction Outer movement, far from the syringe on carrier chain 10.

The utility model proposes medical fluid it is pre- it is filling during the pre- filling apparatus of syringe, directly contained in syringe inner cavity Medical fluid improves medical fluid utilization rate, reduces liquid waste.
