Then the second turntable rotates to enable the hair sleeves to enter an inner core clamping station and enter the inner core for insertion by the inner core clamping device.

The outside of the sleeve processing area 2 is also provided with a vibration disk 4, and the vibration disk 4 can directionally and orderly provide the inner core of the sleeve. The second rotating disc 41 is used for completing the actions of inserting the inner core into the inner end of the wool sleeve and inserting the finished product off-line. The second rotary table 41 is driven by a servo motor 405, the inner cores are fed by a vibrating disc 4, the vibrating disc uniformly outputs the inner cores in the basket in a directional manner and sequentially conveys the inner cores to the first sandwich slot 43, a third displacement mechanism 401 is parallel to the second sandwich slot 42, the second sandwich slot 42 is lower than the position of the first sandwich slot 43, one side of the first sandwich slot 43 is provided with a movable push plate and a third displacement mechanism 401, the third displacement mechanism 401 acts to push one inner core conveyed to the tail end to the second sandwich slot 42 so that the inner core falls in the second sandwich slot 42, the front end of the second sandwich slot 42 is forward to the sleeve of the clamping station of the second rotary table, the rear end of the second sandwich slot 42 is provided with a fourth displacement mechanism 402, the fourth displacement mechanism acts to push the inner core into the blank in the sleeve 411, one side of the clamping station of the second rotary table is provided with a positioning plate 403, the positioning plate 403 covers the disc changing station and the clamping station, close to the end of the hair sleeve, the hair sleeve is axially positioned, thereby smoothly completing the assembly and processing of the inner core. The movable push plate is provided with an anti-falling upper cover which spans over the inner core, so that the inner core can not leave the first core clamping groove from the upper part.

After the inner core is clamped, the second rotary table rotates to transfer the rough sleeve to a wire inserting station, the fifth displacement mechanism pushes the wire inserting push rod to push the finished rough sleeve out of the sleeve, the wire is inserted from the blanking shovel, and the roller rough sleeve is machined.

Referring to fig. 13, in order to adapt to the clamping of cores with different specifications, when a small-sized core is assembled, the length of the small-sized core is approximately the same as that of the movable push plate and the anti-falling upper cover, at this time, a baffle 45 is required to be arranged at the tail end of the first core clamping groove 43 to prevent the penultimate core from falling from the gap.

The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
