Screw clamping mechanism for uncoiling machine

Abstract

The invention relates to a screw clamping mechanism for an uncoiling machine. The screw clamping mechanism comprises frames arranged symmetrically on two sides, an unwinding shaft, a guide wheel and an upper support beam; two ends of the unwinding shaft and two ends of the upper support beam are arranged on the frames on the two sides; two ends of the guide wheel are arranged on the frames on the two sides through a guide wheel seat; the upper support beam is provided with an uncoiling arm with a bend; two ends of the uncoiling arm are respectively provided with a driving wheel and a driven wheel; a belt is wound on the driving wheel and the driven wheel; a lower support beam is arranged between the two frames and is provided with an uncoiling arm pushing device; the outer sides of the frames are provided with unwinding shaft clamping devices which comprise clamping pieces and screws. The screw clamping mechanism has the beneficial effects that the clamping devices are arranged at two ends of the unwinding shaft, and a phenomenon that along the decreasing of the diameter of a cloth roll or a paper roll, the pressure of the cloth roll or the paper roll on the unwinding shaft is decreased, and the unwinding shaft is easily jacked by a support mechanism, is separated from a support and is instable in the unwinding process can be prevented.

Description

technical field [0001] The invention relates to the technical field of paper or cloth cutting production, in particular to a screw clamping mechanism for an unwinding machine. Background technique [0002] In the production process of textile cloth or kraft paper, art paper, etc., it is necessary to unwind the rolled cloth roll or paper roll, which requires the use of an unwinder. The diameter of the cloth roll or paper roll will become smaller and smaller during the unwinding process of the unwinder, and the stability of its unwinding speed will become worse and worse as the diameter of the cloth roll or paper roll decreases, which will affect the subsequent The work flow reduces the production efficiency. In order to stabilize the unwinding speed, people set up a support mechanism for the cloth roll or paper roll on the unwinder. This mechanism can change its position as the diameter of the cloth roll or paper roll decreases, and is always supported at The outermost circl...

The diameter of the cloth roll or paper roll will become smaller and smaller during the unwinding process of the unwinder, and the stability of its unwinding speed will become worse and worse as the diameter of the cloth roll or paper roll decreases, which will affect the subsequent The work flow reduces the production efficiency. In order to stabilize the unwinding speed, people set up a support mechanism for the cloth roll or paper roll on the unwinder. This mechanism can change its position as the diameter of the cloth roll or paper roll decreases, and is always supported at The outermost circle of the cloth roll or paper roll, but as the diameter of the cloth roll or paper roll decreases, its own weight will also decrease, and it is easily lifted by the supporting mechanism, so that the unwinding shaft of the cloth roll or paper roll is detached from the bracket
