Paperboard processing device

Abstract

The invention belongs to the field of paperboard processing devices, and particularly relates to a paperboard processing device. The paperboard processing device comprises a guiding cavity used for guiding a paperboard to a cutting position; through holes are symmetrically formed in the middle of the guiding cavity; cutting cavities are fixed on the through holes; the inclination angles of the cutting cavities are the same as a honeycomb line of a paper core; blades are arranged in the cutting cavities in a sliding mode; limiting blocks are arranged at the tops of the blades and are connected to the upper edges of the cutting cavities through springs; the two sides of the outlet of the guiding cavity are provided with round rollers capable of driving the paperboard to be discharged; and cams are hinged to the round rollers through connecting rods and can rotate to beat the limiting blocks. According to the paperboard processing device, the paperboard is driven to be discharged mechanically through the special structure so that the cutting efficiency can be improved; and in addition, notches are smooth, the subsequent combination of paperboards is facilitated, and artificial modifying and cutting are not needed.

Description

technical field [0001] The utility invention belongs to the field of cardboard processing equipment, and in particular relates to a cardboard processing equipment. Background technique [0002] As we all know, cutting the honeycomb paper core is an essential process in the production process of the honeycomb paper core, and the quality of the cutting device design directly affects the production efficiency and production quality of the honeycomb paper core. [0003] At present, Chinese patent authorization announcement number CN100586671C discloses a shearing mechanism for a honeycomb paper core automatic production line, including a frame and a shearing device. There is an arc-shaped paper guide plate above the table, and a lifting mechanism that can adjust the height of the table is provided below the above machine table. The shearing device includes a fixed cutter, a movable cutter, and a driving mechanism, wherein: the fixed cutter and the movable cutter are vertically ...

AI Technical Summary

Problems solved by technology

[0004] However, there is a problem in the above patent. The honeycomb paper core that needs to be cut slides down from the paper guide plate by its own weight to discharge the material. The cardboard is easy to bend, and the equipment is easy to be stuck if the material is not discharged in time, which greatly limits Improve the production efficiency of honeycomb paper core

In addition, because the honeycomb paper core is discharged by its own weight, it cannot be effectively fixed during the cutting process, and it is easy to shift during the cutting process, which reduces the flatness of the cutting

[0005] There is still a problem. When these devices are cutting honeycomb cardboard, the cutting direction of the cutter does not conform to the grain direction of the paper core. As a result, it is not easy to cut when cutting. Forcibly cutting the cardboard will cause the cardboard to be cut. It is messy and even pitted, which is not convenient for the combination or processing of the cut cardboard, and it needs people to re-decorate the cut
