And then the second turntable rotates to enable the wool sleeve to enter the inner core clamping station, and the wool sleeve enters the insertion of the inner core through the inner core clamping device.

The outside of the sleeve processing area 2 is also provided with a vibrating disc 4, and the vibrating disc 4 can directionally and orderly provide the inner core of the sleeve. The second rotary table 41 is used for completing the actions of inserting the inner core at the inner end of the wool sleeve and discharging the finished product. The second turntable 41 is driven by a servo motor 405, the inner cores are fed by a vibrating disc 4, the vibrating disc uniformly and directionally outputs the inner cores in the basket, the inner cores are sequentially conveyed into a first clamping groove 43, a third displacement mechanism 401 is parallel to the second clamping groove 42, the second clamping groove 42 is lower than the first clamping groove 43, a movable push plate and a third displacement mechanism 401 are arranged on one side of the first clamping groove 43, the third displacement mechanism 401 acts to enable the movable push plate to push one inner core conveyed to the tail end to the direction of the second clamping groove 42, the inner cores fall into the second clamping groove 42, the front end of the second clamping groove 42 is forward to a sleeve of a second turntable clamping station, a fourth displacement mechanism 402 is arranged at the rear end of the sleeve, the fourth displacement mechanism acts to push the inner cores into a wool sleeve in the sleeve 411, a positioning plate 403 is arranged on one side of the second turntable clamping station, the positioning plate 403 covers the disc changing station and the clamping station, and is close to the wool sleeve end, and the wool sleeve is axially positioned, and accordingly assembly and machining of the inner cores is completed smoothly. The movable push plate is provided with an anti-falling upper cover which spans the inner core, so that the inner core cannot leave the first sandwich groove from the upper side.

After the inner core is clamped, the second rotary table rotates to rotate the wool sleeve to a lower line station, a fifth displacement mechanism pushes a lower line push rod to push a wool sleeve finished product out of the sleeve, the wool sleeve is shoveled off from the blanking, and the processing of the roller wool sleeve is completed.

Referring to fig. 13, in order to accommodate the clamping of cores of different specifications, when assembling cores of small specifications, the length of which is approximately the same as that of the movable push plate and the anti-drop cover, a baffle 45 needs to be provided at the end of the first core slot 43 to prevent the penultimate core from falling from the notch.

The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
