Abstract

The invention relates to a winding and unwinding device for a printing machine. The winding and unwinding device for the printing machine is characterized in that the winding and unwinding device comprises a transmission shaft (1), an air pressure mechanical chuck (2) used for the winding and unwinding of the printing machine is arranged at one end of the transmission shaft (1), a screw nut base (3) used for driving the transmission shaft (1) to move in the axial direction is arranged at the other end of the transmission shaft (1), a ball screw (4) used for driving the screw nut base (3) to move is connected to the screw nut base(3), a screw rod synchronous wheel(5) used for driving the ball screw(4) to rotate is arranged at one end of the ball screw (4), a synchronous belt (6) is arrangedon the screw rod synchronous wheel (5), a motor synchronous wheel (7) is arranged on the synchronous belt (6), a speed reducing motor (8) is arranged on the motor synchronous wheel (7), and a rotating device (9) is arranged on the transmission shaft (1). The winding and unwinding device for the printing machine has the advantages of being easy in unloading and automatic in centering, shortening downtime, reducing labor intensity of employees, and improving the production efficiency, safety and reliability.

Description

【Technical field】 [0001] The invention relates to a winding and unwinding device for a printing machine. 【Background technique】 [0002] The existing printing machine for rewinding and unwinding adopts an integral air expansion shaft, which is inconvenient for loading and unloading materials, manual centering, large errors, difficult centering when the roll material is heavy, low production efficiency, and small adjustable range; it is safe to use cylinder clamping performance, poor reliability, etc. [0003] Due to the above-mentioned problems, it is necessary to propose a solution, and the present invention is made under such a background. 【Content of invention】 [0004] The technical problem to be solved by the present invention is to provide a printing machine rewinding and unwinding device for the shortcomings of the above-mentioned prior art, which is convenient for loading and unloading materials, automatically centered, and reduces Downtime, reduce labor intensit...
