AI Technical Summary
In existing technologies, collisions between the filling needle and the ampoule neck can cause foreign objects to fall off and the liquid medicine to stick to the neck and carbonize, affecting product quality and increasing production costs and labor intensity.
A guide sleeve device was designed to prevent the filling needle from colliding with the bottle mouth. The ampoule is positioned using a positioning seat and guide claws, and filling is carried out through the guide hole to avoid contact between the filling needle and the bottle mouth. Combined with the vent hole, air inside the bottle is discharged.
It effectively prevents foreign matter from falling off and the liquid from carbonizing, improves production efficiency, reduces labor intensity and costs, and reduces the foreign matter rate and carbonization rate in the bottle from 3% to 1%.

[0004] The guiding sleeve device for preventing needle filling from colliding with bottle mouth, comprising positioning seat, positioning seat is rotary body, and the bottom end of positioning seat is connected with a plurality of guiding claw pieces;Positioning seat is provided with positioning conical surface for contacting ampoule bottle mouth and positioning ampoule;Positioning seat is provided with guiding hole for guiding needle to pass through;Positioning seat and guiding claw piece are made of soft material.
[0005] The technical scheme of the utility model provides a guiding sleeve device for preventing needle filling from colliding with bottle mouth, which can accurately position needle filling when needle enters ampoule bottle mouth to fill liquid medicine, prevent needle from colliding with ampoule bottle mouth to cause foreign matter to fall off, avoid liquid medicine filled to stick to bottle mouth to cause carbonization during fusion sealing, save production cost, improve production efficiency and reduce labor intensity of workers.
[0006] Preferably, the guiding claw piece is in the shape of a circular arc, and each guiding claw piece is arranged in a circumferential array, and the bottom end of the guiding claw piece is provided with a chamfer to facilitate the entry of the guiding claw piece into the ampoule bottle.
[0007] Preferably, the guiding hole is provided with a plurality of air vents arranged in a circumferential array at the edge thereof, for discharging air in the ampoule bottle during filling.
[0008] Preferably, the diameter of the upper part of the positioning conical surface of the positioning seat is greater than the inner diameter of the ampoule bottle mouth.
[0009] Preferably, the diameter of the outer edge of the guiding claw piece is less than the inner diameter of the ampoule bottle mouth.
[0010] The utility model has the beneficial effect that compared with the prior art:
[0011] 1、 the utility model can effectively prevent the foreign matter of ampoule bottle mouth caused by filling needle collision from falling off;
[0012] 2、 the utility model can avoid the influence of product quality caused by the carbonization of fusion seal of the liquid medicine sticking to the ampoule bottle mouth during filling;
[0013] 3、 the utility model has simple structure, can greatly improve work efficiency, reduce labor intensity and save cost;The foreign matter rate and carbonization rate in the bottle are reduced from the original 3% to 1%. BRIEF DESCRIPTION OF DRAWINGS
