The motor 1, gearbox 2, and divider 3 are connected in sequence. The power output of the motor 1 is reduced by the gearbox and then transmitted to the divider 3. The crankshaft end of the divider 3 is connected to the cam crankshaft mechanism 4 and outputs constant speed rotation power to the cam crankshaft mechanism 4. The intermittent transmission mechanism of the divider 3 causes the divider flange to rotate intermittently.

[0029] The pressure rod assembly 6 includes a slide table floating connecting plate 60, a slide table pressure rod mounting plate 61, a slide table connecting rod 62, and a slide table reinforcing connecting rod 63. Two slide table connecting rods 62 and one slide table reinforcing connecting rod 63 are respectively fixedly connected to the slide table floating connecting plate 60 and the slide table pressure rod mounting plate 61. The slide table floating connecting plate 60 is connected to the cam crankshaft mechanism. The continuous movement of the cam crankshaft mechanism causes the slide table pressure rod mounting plate 61 to reciprocate. The slide table pressure rod mounting plate 61 is equipped with a pressure clamp push-in needle 66 and a pressure cover rod 67. During the movement of the slide table pressure rod mounting plate 61, the pressure clamp push-in needle 66 and the pressure cover rod 67 simultaneously push the inner clamp and the core cover into the sleeve core.

[0030] The turntable assembly 5 includes a connecting block 50, an internal gear ring 51, a third turntable 52, a first turntable 53, and a second turntable 54. The connecting block 50 fixes the internal gear ring 51 to the third turntable 52, and the gear ring 50 is evenly distributed with equal arcs around its circumference. The third turntable 52 is mounted on the divider flange and is driven by the divider to rotate intermittently. The first turntable 53 and the second turntable 54 are respectively equipped with driven gears 531 and 541, which mesh with the internal gear ring 51. Therefore, when the internal gear ring 51 rotates, the first turntable 53 and the second turntable 54 rotate synchronously.

[0031] The supporting system 7 comprises a main bearing seat plate 71, a connecting rod bearing seat plate 72, a pressing rear baffle 73, a cover distribution disc outer baffle 74, a supporting side plate 75, an inlet material blocking block 76, and an inner clip distribution disc baffle 77. The main bearing seat plate 71 is provided with two bearing seats 711 respectively, and bearings are arranged on the bearing seats. The rotating shafts of the upper and lower distribution discs of the rotating disc assembly are arranged in the bearings, so that the two distribution discs can rotate smoothly. The connecting rod bearing seat plate 72 is installed on the bottom plate and comprises two straight plates which are arranged vertically and in parallel. Bearing seats and bearings are arranged on the straight plates, and the bearings support the two slide table connecting rods 62 to move back and forth on the connecting rod bearing seat plate 72. The pressing rear baffle 73 comprises a second pressing rear baffle 732 close to the third rotating disc 52 and a first pressing rear baffle 731 away from the third rotating disc 52. The two baffles are suitable for assembling brush sleeve of different lengths. When the brush sleeve is long, the first pressing rear baffle 731 is used, and when the brush sleeve is short, the second pressing rear baffle 732 is used. The pressing rear baffle 73 is arranged behind the third rotating disc 52 and covers the assembly position of the core cover and the inner clip. When the core cover and the inner clip are pushed by the slide table pressing rod mounting plate 61 towards the sleeve core, the pressing rear baffle 73 bears the pushing force transmitted by the core cover and the inner clip, preventing the sleeve core from separating from the third rotating disc 52. The first pressing rear baffle 731 is provided with a fixing groove 7311 which is divided into upper and lower parts. The first pressing rear baffle 731 is fixedly installed on the divider 3 by the fixing groove 7311 and fastening screws 95, and the bottom edge is fixed on the bottom plate 9. Considering the feasibility of feeding long sleeve cores from the through groove 90, when assembling short sleeve cores, the second pressing rear baffle 732 needs to be suspended above the through groove 90. Therefore, the second pressing rear baffle 732 is detachably installed on the first pressing rear baffle 731 by a distance limiting cylinder sleeve 733 and fastening screws. Similarly, the first pressing rear baffle 731 is also detachably fixed on the divider 3 and the bottom plate 9 to adapt to the assembly and processing of sleeve cores of different lengths.

[0032] The gears on the back of the first rotating disc 53 and the second rotating disc 54 are engaged with the inner teeth of the inner gear ring 51, so that the two rotating discs rotate synchronously with the third rotating disc 52. The first rotating disc 53 and the second rotating disc 54 have the same diameter and are provided with three workpiece recesses at equal distances from the edges of the discs. The workpiece recesses are used to accommodate the core cover and the inner clip after feeding. The workpiece recesses have openings in the radial direction of the disc. In order to keep the core cover and the inner clip in the correct position after feeding, the inner clip distribution disc baffle 77 and the cover distribution disc outer baffle 74 are arranged on the sides of the first rotating disc 53 and the second rotating disc 54 respectively. A distribution group pad plate is arranged on the bottom plate 9. The cover distribution disc outer baffle 74 is fixedly installed on the pad plate. The working end face of the cover distribution disc outer baffle 74 is arc-shaped. The working end face starts from the feeding position of the cover distribution disc and covers the pressing position of the cover distribution disc.

[0033] In order to prevent the core cover and the inner clamp from falling off, the inner clamp guard 771 is installed on the inner clamp distribution plate guard 77, and the core cover guard 741 is installed on the cover distribution plate outer guard 74. The main parts of the two guards are similar to the two distribution plate guards, and both of them extend to the distribution plate, so that their working surfaces shield the partial edges of the two distribution plates. Thus, the rear side of the core cover and the inner clamp in the distribution plate is stopped by the ring gear 51, and the front side is stopped by the core cover guard 741 or the inner clamp guard 771.

[0034] In order to make the feeding accurate, the core cover feeding sleeve 742 and the inner clamp feeding sleeve 772 are respectively arranged at the feeding ports of the two distribution plates. The core cover feeding sleeve 742 is installed on the cover distribution plate outer guard 74, and has a surrounding barrier that partially surrounds the circumference of the core cover. The inner clamp feeding sleeve 772 is installed on the inner clamp distribution plate guard 77, and has a sleeve that is suitable for the insertion of the inner clamp, and the side wall of the sleeve is open. The bottom of the cover distribution plate outer guard 74 is also provided with the core cover support plate 743, and the top of the core cover support plate 743 has an arc-shaped recess that is adapted to the pressure cover rod 67, so that the pressure assembly of the core cover is more stable.

[0035] The blanking piece 91 is installed on the bottom plate 9 of the edge of the blanking groove 92. When the assembled sleeve core is rotated to the lowest position with the ring gear 51 and the third rotating disc 52, the blanking piece 91 is inserted into the sleeve core, and the sleeve core is pushed downward and falls down, and then is discharged through the blanking groove 92. The top and bottom of the slide table pressure rod installation plate 61 extends the installation arm, and the opening slot 611 is arranged on the installation arm. The clamping adjusting screw hole 612 is arranged on the outer wall of the opening slot, and the pressure clamping push-in needle 66 or the pressure cover rod 67 is installed at the bottom of the opening slot. The rod segment of the pressure cover rod that extends out of the opening slot includes the pressure cover cylinder 671 and the guide needle 672.

[0036] The above embodiments are the preferred embodiments of the present application, but the embodiments of the present application are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principles of the present application shall be equivalent replacement methods, and shall be included in the protection scope of the present application.
