FIGS. 1-5 provide an existing clamping mechanism, comprising: a cylindrical clamping head a, a lock nut b, a support bar c and a ball d; in the figure, the upper end of the clamping head a is provided with a cylindrical accommodating groove a-1, the accommodating groove a-1 is used for accommodating a sealing plug cap f, the side wall of the accommodating groove a-1 is provided with a cylindrical channel hole a-2 from outside to inside, wherein the aperture near the side of the accommodating groove a-1 is smaller than that of a channel, a ball d is arranged in each channel, a supporting bar c extending out of the channel is also arranged in each channel, the supporting bar c supports the ball d towards the accommodating groove a-1, the part of the clamping head a with the diameter larger than that of the outer wall of the accommodating groove a-1 is provided with external threads, the internal threads of a locking nut b are matched with the external threads, and under the action of the top pressure of the side wall of the locking nut b on the supporting bar c, the ball d is pressed into a chute f-1 formed in the outer wall of the sealing plug cap f. The pre-compression mechanism of the injector filling and plugging machine adopts an air cylinder, under the clamping of filling fingers to an injector g filled with liquid medicine, the air cylinder rises to push the tightening mechanism, the sealing plug cap f and the lower port of the injector g are pre-compressed firstly, then the sealing plug cap f is screwed onto the injector g by providing rotary driving force through a screwing motor of the tightening mechanism, and a sliding groove f-1 of the sealing plug cap f is clamped and fixed by a ball d in the process of screwing the sealing plug cap f. However, in the process of screwing the sealing plug cap f, the rolling of the ball d can cause the slipping phenomenon of the sealing plug cap f in the clamping process, so that the sealing plug cap f cannot be screwed stably, the sealing plug cap f and the syringe g cannot be screwed, the sealing plug cap f is loosened, a large amount of unqualified syringe filling products are generated, and a large quality hidden trouble exists.
After the sealing plug cap f is pre-compacted with the injector, the balls d are propped by the supporting bars c under the locking action of the locking nuts, so that internal and external movements cannot be performed, and when the sealing plug cap f is installed in the accommodating groove a-1 of the clamping head a, the phenomena of inaccurate alignment and deviation occur, namely, the balls d protruding into the accommodating groove a-1 are not corresponding to the position of the sliding groove f-1 of the sealing plug cap f, so that the sealing plug cap f is slipped in the screwing process, the sealing plug cap f cannot be screwed with the injector g, and a large number of unqualified injector filling products are easy to generate.
