The annular rack is arranged between the upper limit guide wheel and the lower limit guide wheel and meshed with the driving gear. The yarn punching wheel is arranged on the annular rack.

[0010] When the wheel motor is started, the driving ring gear drives the annular rack to move in an arc between the upper and lower limit guide wheels, and then drives the beating-up wheel to send the yarn into the cutting point between the rubber roll and the cutting roll according to the arc-shaped contour of the rubber roll or the cutting roll.

[0011] The automatic yarn feeding by the arc-shaped beating-up device can accurately press the yarn into the cutting point between the rubber roll and the cutting roll according to the arc-shaped contour of the rubber roll or the cutting roll, thereby improving the efficiency of the head yarn feeding or the head yarn changing and the yarn feeding accuracy.

[0012] Further, the arc-shaped beating-up device of the on-line continuous cutting machine further comprises a beating-up seat, and the upper and lower limit guide wheels are arranged in the beating-up seat, and the beating-up seat is arranged on the cutting machine frame.

[0013] Further, the beating-up seat comprises an upper seat plate, a lower seat plate and a cover plate, the upper and lower seat plates are arranged on the upper and lower sides of the cover plate and define a beating-up seat cavity in the cover plate, and the upper and lower limit guide wheels are arranged in the beating-up seat cavity, and the annular rack passes through the beating-up seat cavity between the upper and lower limit guide wheels.

[0030] The beating wheel motor 10 is arranged on the short cutting machine rack and is drivingly connected to the driving gear 20, which can rotate clockwise or counterclockwise under the action of the beating wheel motor 10.

[0031] The yarn beating seat 70 has a shell structure, comprising an upper seat plate, a lower seat plate, and a cover plate; the upper seat plate and the lower seat plate are arranged on the upper and lower sides of the cover plate and define a yarn beating seat inner cavity on the cover plate; the upper limit guide wheel 40 and the lower limit guide wheel 50 are arranged in the yarn beating seat inner cavity. The upper seat plate, the lower seat plate, and the cover plate are fixedly connected or integrally formed.

[0032] The yarn beating seat 70 is fixedly arranged on the short cutting machine rack, the ring gear 30 is arranged between the upper limit guide wheel 40 and the lower limit guide wheel 50 and is in meshing engagement with the driving gear 20. The number of the upper limit guide wheel 40 and the lower limit guide wheel 50 is both two.

[0033] The yarn beating wheel 60 is hingedly arranged on the ring gear 30 and can rotate during yarn beating or pressing. The yarn beating wheel can reduce the friction between itself and the yarn by rotating itself, thereby avoiding damage to the yarn.
