Abstract

The utility model relates to a slotted paper core of a honeycombed paperboard. The end face of the honeycomb paper core is provided with a vent groove or an exhaust hole is arranged in the honeycomb paper core; the vent groove can be made into a square shape, a triangle shape, a circle shape or a half moon shape and can be provided with a groove at the one side or at both sides. The end face (the sides) or the side face center of the honeycomb paper core is provided with the vent groove or the exhaust hole to cause the gas coated with the paper at both sides to discharge along the groove or the hole. The honeycomb paperboard made of the paper core has a flat surface and high quality, and can not be wrapped with gas bubbles.

Description

The fluting refill of honeycomb cardboard

The utility model relates to the refill structure of honeycomb cardboard, belongs to packing of product technical field, particularly relates to the production of carton board.

Honeycomb cardboard be to paper roll after uncoiling, through haulage gear, carry out gluing clocklike and---shear that---stacked------------------upper and lower facial tissue is compound, and---heating---flattens typing, cools off---and operation such as cuts and make the butt joint of bar shaped refill cut paper platen in the facade gluing in refill stretchings.Be the production of honeycomb paper core before the glue process on facade, the honeycomb cardboard that adopts honeycomb paper core to make has very high intensity, not only can make Packaging Box, can also be used for construction material, storage bracket tray etc.But in existing honeycomb cardboard is produced, answer paper by two sides to honeycomb paper core, the phenomenon that often occurs " wrapping up in gas " in the cardboard, these bubbles that are enclosed in the hexagon honeycomb not only make paperboard surface uneven, and outward appearance is ugly, has also seriously influenced product quality, because bubble makes facial tissue separate with refill, do not paste clothes, in case the foreign object collision will produce and break and come off.

The purpose of this utility model is in order to overcome the defective of prior art, and honeycomb paper core is shaped on the fluting structure of losing heart, and makes the honeycomb cardboard of moulding can not wrap up in the honeycomb paper core of bubble between facial tissue and refill.

The technical scheme of the utility model honeycomb cardboard fluting refill is: be shaped at the end face of honeycomb paper core on the side of air channel or honeycomb paper core and be shaped on steam vent.The shape of the air channel of honeycomb paper core end face is square or triangle or circle or semilune.The air channel of honeycomb paper core end face is a single or double, and promptly an end face is slotted, or both ends of the surface all can be slotted.

The utility model discloses a kind of refill that has the honeycomb cardboard of the groove that loses heart, air channel or steam vent have been opened in end face (on the limit) or center, side at honeycomb paper core, make that gas releases along groove or hole when going up two facial tissues again, compared with the prior art, the cardboard made from this honeycomb paper core has surfacing, do not wrap up in bubble, quality is good, characteristics such as intensity height.

Fig. 1 is that the end face (on the limit) of the utility model honeycomb paper core has been opened the air channel schematic diagram;

Fig. 2-Fig. 4 is that the utility model honeycomb paper core air drain that end face is opened is square, triangle or semilune structural representation;

Fig. 5 is that two end faces of honeycomb paper core of the present utility model are shaped on the air channel schematic diagram;

Fig. 6 is shaped on circular row pore schematic diagram in the honeycomb paper core of the present utility model.

Below in conjunction with Fig. 1-Fig. 6 embodiment of the present utility model is done detailed explanation.

The utility model relates to honeycomb cardboard, and particularly the honeycomb paper core 1 of honeycomb cardboard is made steam vent 8 in the middle of the end face that is honeycomb paper core 1 is opened system air channel 3 or side, and the planform of air channel is a lot, as shown in Figure 2, is square air channel 4; As shown in Figure 3, be triangle air channel 5; As shown in Figure 4, be semilune air channel 6; As shown in Figure 5, be that two end faces are shaped on air channel 7; As shown in Figure 6, be to be shaped on circular row pore 8 in the honeycomb paper core.

Claims

1, the fluting refill of honeycomb cardboard, the end face that it is characterized in that honeycomb paper core (1) are shaped on the side of air channel (3) or honeycomb paper core (1) and are shaped on steam vent (8).

2, the fluting refill of honeycomb cardboard as claimed in claim 1, the shape that it is characterized in that the air channel (3) of honeycomb paper core end face is square or triangle or circle or semilune.
