Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing corrugated paperboard, linear board, and similar materials, and these materials are collectively referred to herein as corrugated paperboard, linear board, and similar materials. -If you call it ``do'', it will be changed.

A wide variety of corrugated configurations are known and are used in a variety of ways in the packaging industry.For example, double-sided Dangor is known, which is made by fixing a corrugated fluted intermediate medium between two layers of liners. It is being Also known is a double-screen danboard consisting of a central liner, inner and outer liners, and a nine-wave fluted intermediate medium fixed therebetween.

In the first step of Dan's first grade, one side of the liner layer is glued to the flute medium or surface, and then the adhesive is applied to the corrugated side of the composite material. is coated, and at least one of the round materials treated in this way is coated with
Running part (double-sided, double-sided or other waveforms depending on the direction)
is supplied together with the first layer of liner to a device that fixes the second layer as part of the Dannon fixing operation.

The equipment that performs this commanding operation is known as a double packer, which consists of a heating and compression section upstream of the rounding that dries the adhesive and seals it between each layer, and a gate pulling section within the equipment. It consists of a traction part for The gate is cooled while in the traction station and then cut and/or grooved and/or printed according to specifications.

A conventional double packer has one upper endless belt running along its entire length through the heating section and the traction section. This upper ruto is usually made of textiles and is expensive.

The heating section is provided with a heating section, which is usually driven by a heating surface (e.g. run by a hot plate, hot grate or steam chamber) and a p--de is located between the heating surface and the running section of the first belt. It is arranged so that

In the downstream or traction section, a lower second belt is arranged such that the gate is located between the first and second belts at this location.

In the heating section, pressure is applied to the back side of the belt by, for example, a pressure chamber in the roller, so that when the gate passes through this section, the belt is pressed against the heating surface. In this way, the adhesive is allowed to dry or sinter, and the layers are bonded together. By using the upper endless woven fabric belt, the moisture generated in the heating and pressing section is absorbed.

In the traction section of a conventional double packer, pressure is applied by a weight-adjustable row 9 to the back side of the Ill and second belts, thereby gripping the l-do between the belts and pulling it through the device. ing.

In the present invention, a heating section is provided on the upstream side and a traction section is provided on the downstream side, a heating means is provided on the upstream side for heating the door passing through this section, and a heating section is provided on the downstream side. First and second endless belts are provided to form facing running portions for holding the I-rod, and the running portions of these first and second end belts are connected to each other for holding the female-rod. A waveform characterized by being provided with pressing means for pressing towards each other? - Provides a fixing device between gate layers during board manufacturing.

The means for pressing the first and second endless belts towards each other may be an O-9 or, more preferably, a pressure chamber for applying gas pressure to at least one of the belts.

The means for applying gas pressure to the running paths of the first and second endless belts is at least one pressure chamber provided on the back side of the belt running section, and the pressure chamber cooperates with a device that pressurizes and supplies air. It is preferable to do so. Air pressure acting on the back side of the belts acts to push the belts towards each other to hold the gate. Preferably, the pressure chamber acting on the run of the lower belt has a perforated plate (for example a steel plate) over which the lower belt floats.

If pressure chambers are used to apply pressure to the back side of the Isl and second belts, these belts are preferably made of a non-porous material (such as the conventional ones of Dem or PvC), so that the gas Pressure is used to effectively press the belt against the guard.

The use of gas pressure in the traction section, especially as provided by an air blenheim, makes it possible to compress the belt uniformly, as is often the case when pressing with rollers. - It has the advantage of preventing crushing of the board.

Alternatively, a pressure chamber may be used to apply pressure to one of the first and second belts, and conventional suppression means (e.g. rollers) may be used for the other belt.

Preferably, the heating and suppressing section (upstream side) is provided with a third endless belt (separately from the first and second helix belts) and means for pressing the running section of this belt. Such means may be rollers by weight or preferably tt, <
is a pressure chamber that applies gas pressure to the back side of the third belt, #
Is it okay to leave the pressure chamber the entire width of the third belt? Preferably something that causes heat.

The pressure chamber can also be combined with a gravimetric roller.

The means for heating the I-dore in the heating and suppression section is provided by a heating surface (e.g. provided by a heating latin, hot grate, or steam chamber) to which the I-doe is to be pressed (e.g. by the third belt mentioned above). 6 is preferred.

By using the belts of the traction section without extending them to the heating and suppression section, there is the advantage that the material of these belts can be selected to have the performance required only in the traction section. For reasons described later, this is 4! when the heating and pressing section includes another belt. is important. That is, the conditions are different in these two parts; the upstream part has more moisture brought about by the heating and suppression of the I-do, while the traction part has less such moisture. It is. ,.

Therefore, to the present invention. In addition, it becomes possible to select from four different belt materials for the heating section or the traction section. □The belt in the heating section is selected from a porous material (such as a woven fabric with excellent moisture absorption properties), while the belt in the traction section, which does not require moisture absorption, is made of a material with a low coefficient of friction to improve traction performance. High quality materials are selected. Furthermore, when the pressure chamber is used to press and roll the first and second belts of the traction section, these belts can be selected from a non-porous material. Until now, such non-porous belts have been commonly used in the upstream side and the lower fill, but they are cheaper and cheaper than porous woven belts.The present invention is used in the heating section and the traction section. This makes it possible to select an appropriate amount of belts, whereas in conventional devices they were used only as a common belt.

Embodiments of the present invention will be described below with reference to the drawings.
