Cardboard creasing machine front and rear combination creasing device

Abstract

The invention discloses a front-and-back combined creasing device of a paperboard creasing machine and relates to the technical field of the paperboard creasing machine. The front-and-back combined creasing device of the paperboard creasing machine comprises a big fixing wallboard, a linear guide, a small fixing wallboard, an upper creasing beam, an upper creasing wheel, an air cylinder, a lower creasing wheel and a lower creasing flat roll, wherein a square groove is formed in the middle of the big fixing wallboard; the linear guide is fixedly arranged on the big fixing wallboard and located on the bottom side of the square groove; the small fixing wallboard is located in the square groove and arranged on the upper side of the linear guide in a sliding mode; an upper creasing beam fixing frame is arranged on the small fixing wallboard; the upper creasing wheel is arranged below the upper creasing beam through a wheel carrier; the air cylinder is horizontally arranged; one end of the air cylinder is hinged to the big fixing wallboard; the other end of the air cylinder is hinged to the small fixing wallboard; the lower creasing wheel and the lower creasing flat roll are arranged side by side and are located below the upper creasing wheel. The front-and-back combined creasing device of the paperboard creasing machine is simple in structure, does not need to be detached and replaced, saves time and labor, is high in production efficiency, and can keep the creasing height consistent, and the creasing width is not limited.

Description

Technical field: [0001] The invention relates to the technical field of cardboard creasing machines, in particular to a front and rear combined creasing device of a cardboard creasing machine. Background technique: [0002] Cardboard creasing machine is one of the important equipment in the process of cardboard production. There is a set of creasing wheels on the lower side of the existing cardboard creasing machine. In actual production, different types of flat line creasing cardboard and grooved line creasing are often produced. In the prior art, when processing flat-line creasing cardboard, it is necessary to dismantle the concave creasing wheel and replace it with a flat crimping wheel or a flat creasing roller, which will increase the workload, take a long time, and need to be shut down for replacement , reduce production efficiency, in the prior art, there is also a layer of iron plate on the upper side of the concave pressure lower wheel to flatten the line cardboard,...

[0002] Cardboard creasing machine is one of the important equipment in the process of cardboard production.

In actual production, different types of flat line creasing cardboard and grooved line creasing are often produced. In the prior art, when processing flat-line creasing cardboard, it is necessary to dismantle the concave creasing wheel and replace it with a flat crimping wheel or a flat creasing roller, which will increase the workload, take a long time, and need to be shut down for replacement , reduce production efficiency, in the prior art, there is also a layer of iron plate on the upper side of the concave pressure lower wheel to flatten the line cardboard, but the surface of the iron plate itself is difficult to keep flat when laying, which will cause indentation The height of the creasing is different, the quality of the creasing line is poor, and there is another kind of lower creasing wheel that can be switched by three different wheels to achieve the flattening of the line, but due to the limited mechanical position, the width of the flat line cannot be very wide, so Extruded cardboard panels will also have traces, which is difficult to meet customer requirements
