The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of sterile board discharging mechanism embodiment of the present invention, comprises push rod 1 and thimble assembly, and thimble assembly is sealedly attached to opening 21 places of sterile board 20 and passes through opening 21 and sterile board 20 internal communication.Push rod 1 is arranged in thimble assembly and by opening 21 and stretches into sterile board 20, and one end that push rod 1 stretches in sterile board 20 is connected with pushing plate 2, and a bellows 3 being sheathed on push rod 1 is tightly connected between pushing plate 2 and thimble assembly.Thimble assembly is fixedly connected with a back seat 10 being sheathed on push rod 1 away from one end of sterile board 20, is provided with a sliding part being slidedly arranged on push rod 1 between thimble assembly and back seat 10, and this sliding part is slip flange 9.Slip flange 9 is connected with towards a side of thimble assembly the lip ring being sheathed on push rod 1, is connected with for promoting slip flange 9 and to thimble assembly, draws close the pushing tow parts that make sealing member crimp and thimble assembly and push rod 1 force fit form sealing on back seat 10.During discharging, the segment distance of being separated by between slip flange 9 and sealing member and thimble assembly; Discharging completes, before discharging next time, slip flange 9 and sealing member are drawn close to thimble assembly under the promotion of pushing tow parts, make sealing member extrusion, and clamp sleeve assembly and push rod 1 realization sealing (referring to Fig. 2), thereby prevent that extraneous air from entering in sterile board, guarantee the gnotobasis of sterile board.
In the present embodiment, thimble assembly comprises sleeve pipe 7 and connects back seat 10 and be used for forming with sealing member force fit the flange seat 5 sealing.The two ends of sleeve pipe 7 are respectively equipped with the second flange 6 being connected with flange seat 5 and the three-flange 19 being connected with sterile board 20, and bellows 3 is provided with the first flange 4 being connected with flange seat 5.Between the first flange 4, the second flange 6 and flange seat 5 and be equipped with seal ring 8 between three-flange 19 and sterile board 20, prevent gas leakage.
In the present embodiment, between slip flange 9 and flange seat 5, be provided with Compress Spring 11, flange seat 5 is provided with the holding tank 51 that holds Compress Spring 11, and slip flange 9 is provided with the projection 91 of socket Compress Spring 11.In other embodiments, the projection 91 of socket Compress Spring 11 also can be set on flange seat 5, and on slip flange 9, the holding tank 51 that holds Compress Spring 11 be set.While preparing discharging, rely on the restoring force of Compress Spring 11 flange 9 that makes to slide to get back to original position, eliminate sealing, to push away bottle action.
As shown in Figure 3, in the present embodiment, pushing tow parts comprise the disc cam 16 on the bearing pin 17 that is rotationally connected with back seat 10 and are used for the cam driver of disc-shaped cam 16 rotary lifting sliding parts.Cam driver is driving cylinder 14, and driving cylinder 14 can be selected cylinder, electric cylinder etc., and the expansion link of driving cylinder 14 is connected with the pipe link 15 being fixed on disc cam 16, and pipe link 15 is structure as a whole with disc cam 16.
As shown in Figure 4, in the present embodiment, sealing member is Bowl seal ring 12, and Bowl seal ring 12 is fixed on slip flange 9 by pressure ring 13 and threaded fasteners, and flange seat 5 is provided with the groove 53 for coordinating with Bowl seal ring 12.
As shown in Figure 5, in the present embodiment, offer air pressure and detect hole 52 on flange seat 5, one end that air pressure detects hole 52 is communicated with the cavity being surrounded by flange seat 5, Bowl seal ring 12 and push rod 1, and this cavity is communicated with the space between push rod 1 and bellows 3.The other end that air pressure detects hole 52 is connected with compressed gas source with vaccum-pumping equipment respectively by branch pipe tee connection 22, and the gas circuit that air pressure detects between hole 52 and branch pipe tee connection 22 is provided with for detecting the air pressure detector of air pressure in cavity.Sterile board 20 dischargings first seal before completing, start to carry out the processing of next batch of material, then toward air pressure, detect hole 52 and pass into quantitative pressurized air, by observing the demonstration force value of air pressure vacuum detection instrument, change, and judge leak tightness.If force value is unchanged, leak tightness is good, now by vaccum-pumping equipment, vacuumizes, and the air between push rod 1 and bellows 3 is all extracted out, until the demonstration force value of air pressure detector is zero, can start to carry out the processing of next batch of material.
The discharging mechanism of the present embodiment also comprises an above guide wheel 18 that rolls and coordinate with push rod 1, is used for push rod 1 to lead.
As shown in Figure 1 and Figure 2, a kind of freeze drying box device embodiment of the present invention, comprises the sterile board 20 for freeze-drying medicine bottle, is connected with above-mentioned sterile board discharging mechanism on sterile board 20.
Principle of work: while preparing medicine bottle freeze-drying, driving cylinder 14 promotes disc cam 16 and rotates around bearing pin 17 the curved profile pushing tow slip flange 9 that makes disc cam 16, Compress Spring 11 compressive deformations, Bowl seal ring 12 offsets with flange seat 5 under the drive of slip flange 9.Further pushing tow along with disc cam 16, Bowl seal ring 12 starts distortion, final and flange seat 5, push rod 1 and slip flange 9 are fitted, form sealing, thereby stoped outside air to enter in the space between bellows 3 and push rod 1, even therefore bellows 3 leaks, extraneous air can not enter in sterile board 20 yet.After sealing, toward air pressure, detect hole 52 and pass into quantitative pressurized air, by observing the demonstration force value of air pressure detector, change, judge leak tightness.If force value is unchanged, leak tightness is good, now by vaccum-pumping equipment, vacuumizes, and the air between push rod 1 and bellows 3 is all extracted out, until the demonstration force value of air pressure detector is zero, can start to carry out medicine bottle freeze-drying.After freeze-drying completes, driving cylinder 14 is return, restoring force effect lower slider flange 9 at Compress Spring 11 is returned to original position, Bowl seal ring 12 returns back to original state, eliminate sealing, now extraneous air can enter in bellows 3, and push rod 1 starts to push away bottle action, medicine bottle is pushed out sterile board 20 push rod 1 repositions afterwards, prepares to carry out the freeze-drying of next group medicine bottle.
Below be only the preferred embodiment of the present invention, protection scope of the present invention is also not only confined to above-described embodiment, and all technical schemes belonging under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, should be considered as protection scope of the present invention.
