Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a surface-driven rewinding machine, which can solve the problem that the original bulkiness of the substrate cannot be restored due to the excessive tension of the existing rewinding machine when rewinding. The self-weight of the coil produces the problem of external tightness and internal looseness

Abstract

The invention discloses a rewinding machine with a surface drive function, and belongs to the technical field of printing machinery. According to the rewinding machine, a paper rewinding tension detection device is arranged on a paper output channel behind a traction unit; the paper rewinding tension detection device comprises a second swinging rod; one end of the second swinging rod is connected with a floating roll, and a second sensor for detecting a rotating position of the second swinging rod is arranged at the other end of the second swinging rod; a rewinding roll driven through a second variable-frequency motor behind the paper rewinding tension detection device is arranged, and the second variable-frequency motor is connected with the second sensor through a controller; an inflatable shaft for installing a paper reel in a penetrating manner is arranged above the rewinding roll, and in transmission connection with a lifting cylinder controlled by a proportional electromagnetic valve; and the proportional electromagnetic valve is connected with a third sensor for detecting a lifting position of the inflatable shaft through the controller. According to the rewinding machine disclosed by the invention, the problems that an original bulkiness of a printing stock cannot be recovered due to a too high tension during rewinding of an existing rewinding machine, and material reels are tight outside and loose inside due to dead weights can be solved.

Description

technical field [0001] The invention relates to the technical field of printing machinery, in particular to a rewinding machine for a soft and easy-stretch web printing machine. Background technique [0002] In the printing industry, after the roll-to-roll printing, bronzing, compounding and other processing procedures of coil materials, there must be a mechanical device with rewinding function. This device needs to rewind the printing materials into rolls with moderate elasticity and regular shape. material for subsequent processing. Due to the characteristics of rough surface, small tightness and high bulky printing materials such as sanitary base paper and glued dust-free paper, they are easy to stretch and have large elastic deformation. , a certain tension will be applied, but when rewinding, the tension should neither be too loose nor too tight. If it is too loose, the paper roll is not easy to handle, and if it is too tight, the bulkiness of the substrate will be lo...
