Label rewinding machine running at uniform speed

Abstract

The invention relates to the technical field of label equipment, and discloses a label rewinding machine running at a uniform speed. The machine comprises a rack with the top surface and four sides ofthe top end made of stainless steel panels, wherein an electric box is fixedly installed in an inner cavity on one side of the top end of the rack; a code spraying gun is fixedly installed in the middle of the stainless steel panel on the front surface of the rack by a fixing block; and a code spraying baffle is installed at the code spraying end of the code spraying gun. A motor pulley drives adriving rubber roller big pulley during moving, a driving rubber roller small pulley drives a driving plate pulley, and the driving rubber roller big pulley and the driving rubber roller small pulleyare connected together, so that secondary transmission of the driving motor to the driving plate pulley can be achieved; when the linear speed of the label on the driving plate roller exceeds the linear speed of a driving rubber roller assembly, the driving plate pulley slips, and thus, the linear speed of the driving rubber roller assembly is uniform, the running linear speed of the label is uniform, and code spraying for the label at the designated position is facilitated.

Description

technical field [0001] The invention relates to the technical field of label equipment, in particular to a label rewinder running at a constant speed. Background technique [0002] Labels are used to mark product targets, categories or content, and are tools that are convenient for finding and locating targets. In the printing industry, most labels are used to identify product-related instructions, and the rewinding machine related to labels is a kind of It is used for rewinding and cutting of label paper or film, and it plays the role of cutting everything into two. It is a special equipment for paper, mica tape and film. [0003] When the traditional label rewinding machine is winding the label, the diameter of the label on the driving disk gradually increases with time. Since the power remains unchanged, the diameter becomes larger and the line speed also increases. When the label is wound to the end, the speed is very fast. Fast, which is not conducive to printing on th...

Problems solved by technology

[0003] When the traditional label rewinding machine is winding the label, the diameter of the label on the driving disk gradually increases with time. Since the power remains unchanged, the diameter becomes larger and the line speed also increases. When the label is wound to the end, the speed is very fast. Fast, which is not conducive to printing on the label; if the linear speed of the active disk label is adjusted by changing the power of the motor, not only the cost will increase a lot, the life of the motor will be shortened, but also the maintenance will be troublesome
