Tension adjusting device for printing machine

Abstract

The invention discloses a tension adjustment device for a printing machine, which comprises a support column, a working plate is fixedly connected to the side of the support column, and several stretching devices are connected to the support column, and the stretching device includes a One end of the tension spring close to the support column is fixedly connected with a first connection block, and one end of the tension spring away from the support column is fixedly connected with a second connection block, and the end of the second connection block away from the tension spring is hooked on the baffle to open In the through groove of the baffle plate, a connecting shaft is fixedly connected to the axis of the baffle plate, and a first winding device is fixedly connected to the upper surface of one end of the working plate. The present invention can stretch and control the drum from different angles by setting four stretching devices, thereby ensuring the reliability and stability of the tension adjustment of the drum, and the first winding device and the second winding device are set The roll device can sort out the printed matter and reserve space to a certain extent, protect the printed matter, and reduce the influence of the tension on the printed matter.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a tension adjustment device for a printing machine. Background technique [0002] Printing (Printing, Graphic Arts, also using Graphic Communications, that is, graphic communication) is to transfer text, pictures, photos, anti-counterfeiting and other manuscripts to paper, fabrics, plastics, etc. A technology that mass-reproduces the contents of original manuscripts on the surface of materials such as leather. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. [0003] In the literal sense, writing with traces is called printing, and rubbing is called brushing. Use a brush to rub and make traces on other objects, which is called printing. In short, printing is the industry that produces printed matter. The production of printed materials is similar to that of seals. First engrave the sea...
