A stencil-pressing roller mechanism for a carton printing die-cutting machine

Abstract

The invention provides a pressing die printing roller mechanism of a carton printing die-cutting machine. The pressing die printing roller mechanism comprises wallboards on two sides and a printing roller which is connected in a rotating mode in the middle, eccentric bushings are connected between a shaft of the printing roller and the two wallboards in a rotating mode, each eccentric bushing is connected with an air cylinder in a hinged mode, and each air cylinder controls rotation of the corresponding eccentric bushing; eccentric bushing bases are connected between the eccentric bushings and the wallboards in a rotating mode; a planet wheel set mechanism adjusting the phase of the printing roller is arranged on the outer side of the wallboard on one side, a speed reduction motor on the outer side of the wallboard on the other side is fixedly connected with a support, and a mechanism converting rotation of the shaft into axial movement of a screw rod is arranged in the support. The pressing die printing roller mechanism has the advantages that the four functions of die-cutting printing roller phase adjustment, die-cutting pressure adjustment, printing roller axial adjustment and die-cutting working state switching are integrated, state switching is very convenient, the structure is compact, and pressure adjustment is simple and accurate.

Description

technical field [0001] The invention relates to a carton printing die-cutting machine, in particular to a carton printing die-cutting machine press plate roller mechanism. Background technique [0002] Nowadays, carton printing die-cutting machines are widely used in carton packaging manufacturers. At present, the die-cutting pressure adjustment mechanism of carton printing die-cutting machines is usually placed on the die-cutting roller. Such a structure makes the structure of the die-cutting roller more complicated and it is not easy to fail Maintenance, and there is no die-cutting work switching mechanism, resulting in serious damage to the die-cutting knife in the idling state of the die-cutting machine, and the high frequency of use of the die-cutting roller, frequent replacement of the die-cutting roller with a complex structure will also lead to a decrease in production costs improve. Sometimes it is necessary to adjust the axial position of the molding roller during...

Problems solved by technology

[0002] Nowadays, carton printing die-cutting machines are widely used in carton packaging manufacturers. At present, the die-cutting pressure adjustment mechanism of carton printing die-cutting machines is usually placed on the die roller. Maintenance, and there is no die-cutting work switching mechanism, resulting in serious damage to the die-cutting knife in the idling state of the die-cutting machine, and the high frequency of use of the die-cutting roller, frequent replacement of the die-cutting roller with a complex structure will also lead to a decrease in production costs improve

In the production process, it is sometimes necessary to adjust the axial position of the die-cutting roller. This requires the die-cutting knife to be removed and re-fixed.
