Description

Large-scale cardboard both sides are book device in advance

Technical Field

The utility model relates to a bending device, in particular to a device for pre-bending two sides of a large paperboard.

Background

The cardboard is by various paper pulp processing, the thick paper page that the fibre interweaved was constituteed, and the board of beginning is when folding, and the manual operation of folding to the cardboard that carries out of staff more, because the quantity of the cardboard that needs to fold is more, and staff is manual when folding to the cardboard work load great, after folding for a long time, staff's tired sense also increases, and staff's folding efficiency also greatly reduced simultaneously.

In order to improve efficiency, the paper board is processed by a box pasting machine at present. In the packaging and printing industry, the box pasting machine is applied to the last procedure of packaging box processing, namely, the printed and die-cut paper board is folded and formed and pasted, the machine box pasting replaces a manual box pasting mode, the labor cost is reduced, and the efficiency is improved. However, a typical box pasting machine is not provided with a prefolding, but is preferably provided with a prefolding, but is provided with a glue spraying system and other devices. The existing carton bending device has certain defects when in use, such as single-sided pre-folding, which affects folding efficiency. In addition, the paperboard material of some cartons is brittle, and is likely to break in the bending process, so that the material is wasted. The above problems are particularly evident for large-sized paperboards; accordingly, there is a continuing need for improvements over the prior art.

Disclosure of utility model

The technical problem to be solved by the utility model is to provide the device for pre-folding the two sides of the large-sized paper board, wherein the pre-folding of the two sides simultaneously improves the efficiency, is suitable for pre-folding the large-sized paper board, and can avoid breakage possibly occurring in the folding process.

The technical scheme adopted by the utility model for solving the technical problems is to provide a pre-folding device for two sides of a large paperboard, which comprises a bottom plate, wherein one side of the bottom plate is connected with a left folding plate, the other side of the bottom plate is connected with a right folding plate, the left folding plate, the right folding plate and the bottom plate are movably connected through hinges, so that the left folding plate and the right folding plate form a plane with the bottom plate in an opening state, a pre-folding left base plate is arranged on the bottom plate close to the left folding plate, and a pre-folding right base plate is arranged on the bottom plate close to the right folding plate.

The two sides of the large paperboard are provided with the pre-folding device, wherein the front side and the rear side of the bottom plate are provided with the barrier strips.

According to the large paperboard two-side pre-folding device, the front ends of the left folding plate and the right folding plate are outwards protruded to form the arch.

According to the large paperboard two-side pre-folding device, the positioning blocks are arranged on the bottom plate, and the arch and the positioning blocks on the left folding plate and the right folding plate are positioned on the same straight line.

The two sides of the large paperboard are pre-folded, wherein handles are formed on the left folding plate and the right folding plate.

Compared with the prior art, the utility model has the following beneficial effects: the device for pre-folding the two sides of the large paperboard adopts the left folding pressing plate and the right folding pressing plate to simultaneously pre-fold the two sides of the large paperboard to improve the efficiency; the left folding pressing plate and the right folding pressing plate form a plane with the bottom plate in an opened state so as to facilitate the placement of a large paperboard; the cardboard is gradually formed along the edge of the backing plate during pre-folding, so that the quality of the purely manual pre-folding is improved, the efficiency is improved, and the possible breakage in the folding process can be avoided.
