The top of the syringe is always placed on a horizontal tray at the top of the sleeve 10, and after the syringe is destroyed, the syringe on the tray is taken down.
In this embodiment, the position of the inner surface of the sidewall of the first accommodating cavity 2 below the top of the sleeve 10 is uniformly provided with an annular heating wire 21, and the sidewall of the first accommodating cavity 2 is provided with a water outlet 22 controlled by a valve. Before destroying the syringe, earlier to first holding 2 interior water injections, heat water through heater strip 21, heat transfer sleeve 10 with heat behind the water heating, and then transmit for the syringe, the syringe softens after being heated.
In this embodiment, an annular material receiving baffle 23 is fixedly installed on the outer side wall of the sleeve 10 above the first driven gear 20, and the material receiving baffle 23 is used for receiving a piston handle cut by the primary destroying mechanism 16, so as to prevent the piston handle from falling into the bottom of the first accommodating cavity 2, and facilitate collection of the destroyed waste material.
The working process of the embodiment is as follows: after the medical staff uses the syringe, the needle is pulled out and the injection port of the syringe is inserted downwards into the sleeve 10, and after the syringe is inserted into all the sleeves 10, the syringe is destroyed. Water is injected into the first accommodating cavity 2, and the water is heated by the heating wire 21 to soften the injector. The preliminary destroying mechanism 16 is driven by the output shaft of the motor to cut the piston handle of the injector; bringing the sleeve 10 and the syringe into rotation. The effect of the rotary cut is created between the plunger shaft of the syringe and the primary destruction mechanism 16. The cylinder 3 drives the second containing cavity 4 to move downwards, so as to drive the secondary destroying mechanism 18 to rotationally cut the syringe cylinder and the piston rod from top to bottom. The syringe and the piston rod are cut in a rotary mode by the cutting mechanism 184 to generate strip-shaped fragments, and the strip-shaped fragments automatically fall onto the upper surface of the supporting plate 6 at the bottom of the sleeve 10 to destroy the syringe. Drive bevel gear 13 through rotating electrical machines 14 and rotate to drive bevel gear ring 12 and collar 9 and rotate, thereby realize pan feeding mouth 8 and through-hole 11's intercommunication, and then realize the inside intercommunication with the inside waste material chamber of base 1 of sleeve 10, the syringe piece in the sleeve 10 passes through-hole 11 and pan feeding mouth 8 in proper order under the promotion of sleeve 10 lateral wall, falls into waste material chamber and concentrates the recovery.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
