Description

  The present invention relates to a single-sided corrugated cardboard forming machine without internal heating, and in particular, heating devices are provided on two outer sides away from the adhesive application mechanism of one flute wheel of the molding machine base and the pressure reel of the laminating apparatus. The adhesive application mechanism is close to the heating equipment, pre-cured before bonding, and the low temperature operation of the flute wheel and pressure reel can reduce the thermal deformation and extend the entire service life. The present invention relates to a surface corrugated paper molding machine.

The current manufacturing industry is faced with labor shortages, high environmental protection awareness, rising labor costs and management costs, and there is a pressure to shift from labor-intensive to technology-intensive, so many of the manufacturers The line automation technology and jig assistance are used to reduce manpower, save process time and improve production capacity.
In various general paper materials, corrugated paper has advantages such as being convenient for printing, robust and durable, and on the other hand, due to the elastic and seismic performance of the wave-like structure laminated inside the corrugated paper, Goods can be protected, reducing the probability of collision and damage, while being convenient for storage or transportation.

In an automated production process of corrugated paper board, it is subjected to processing processes such as paper bonding, preheating, corrugated cardboard molding, adhesive, cooling, crimping, trimming, cutting and deposition using corrugated paper as a material.
Referring to FIG. 2, it is an explanatory side view of a conventional corrugated paper manufacturing facility. As can be seen from the figure, the molding machine base A includes two flute wheels A1 arranged side by side. The adhesive coating mechanism A2 and the pressure reel B1 of the bonding apparatus B are provided around one flute wheel A1, and the tooth portion A11 is formed on the surface around the flute wheel A1.

When the base paper C passes the gap between two adjacent flute wheels A1 along the flute wheel A1, the base paper C can be rolled using the tooth portion A11 and formed into a flute shape. C is passed along the flute wheel A1 to the adhesive application mechanism A2, the adhesive application mechanism A2 applies the adhesive to the surface of the base paper C, and the base paper C passes through the path between the flute wheel A1 and the pressure reel B1. After that, the surface paper D is rolled and pasted on the surface having the adhesive of the base paper C along the pressure reel B1 and pasted on the single-faced cardboard paper E.
In the process in which the base paper C and the surface paper D perform the molding or pasting operation, first, the heat energy is absorbed by the flute wheel A1 and the pressure reel B1 by a heat source such as boiler steam, an infrared lamp or a heating plate. Thereafter, the surface temperature rises, and the base paper C or the surface paper D is preheated to reach a necessary temperature.
This type of heat source is a direct heating method for the flute wheel A1 and the pressure reel B1, and the adhesive application mechanism A2 is too close to the flute wheel A1 and the pressure reel B1 to be affected by heat and join the adhesive. Pre-cured before, the effect of adhesion of the base paper C and the surface paper D is not good, and the flute wheel A1 and pressure reel B1 are easy to generate thermal deformation phenomenon due to high temperature operation, shorten the overall service life, always It is necessary to stop the equipment to perform maintenance and replacement work, which not only wastes process time and cost, but is also disadvantageous in improving production efficiency, and those working in the industry want research improvement.

  The technical means employed by the present invention and the structure thereof for achieving the above objects and effects will be described in detail with reference to the preferred embodiments of the present invention in accordance with the drawings.

Referring to FIG. 1, it is a side explanatory view of the present invention, and as can be seen from the figure, the present invention includes a molding machine base 1 and a bonding apparatus 2, of which the molding machine base 1 Has at least two flute wheels 11 arranged adjacent to each other, forms a plurality of tooth portions 111 on the peripheral surface of the flute wheel 11, and interlocks the flute wheel 11 between each two adjacent flute wheels 11. A gap 110 through which the base paper 3 can be passed is formed, and an adhesive application mechanism 12 is provided at a location away from the gap 110 around the flute wheel 11 in the molding machine base 1.
The laminating apparatus 2 has at least one pressure reel 21 adjacent to the flute wheel 11 and the adhesive application mechanism 12, and the surface paper 4 on the peripheral surface of the pressure reel 21 is valuable between the pressure reel 21 and the flute wheel 11. The laminating passage 210 is formed, and the heating device 22 of at least one heating wheel 221 is provided on each of the two outer sides of the flute wheel 11 on the laminating apparatus 2 and the adhesive application mechanism 12 of the pressure reel 21.
In addition, a plurality of presser wheels 222 are provided around the heating wheel 221 of the heating device 22 so that the base paper 3 and the surface paper 3 can be pasted on the surface around the heating wheel 221 to perform preheating.

However, the adhesive application mechanism 12 of the molding machine base 1 is composed of an adhesive application frame, a transmission mechanism, an adhesive plate and an adhesive application reel, a thickness determining reel, a pressure reel, and the like. Based on the performance and requirements, the linear velocity difference can be changed, and the purpose of uniform coating can be achieved.
Two heating devices 22 are provided as two preferred embodiments on the two outer sides away from the flute wheel 11 of the bonding apparatus 2 and the adhesive application mechanism 12 of the pressure reel 21, but in actual application, the adhesive of the pressure reel 21 The heating device 22 can also be provided only on the outer side away from the coating mechanism 12, can be heated using a boiler to generate steam, and the steam is transmitted to the inside of the heating wheel 221 via a pipe line. After the heat source is formed and the heating wheel 221 absorbs the heat energy, the surface temperature is quickly raised.
In actual application, the heating wheel 221 can be heated using an infrared heat tube, a heating plate, a heating rod or other heat source, and the base paper 3 or the surface paper 4 is preheated by the heating wheel 221. After reaching the required working temperature, it can be advantageous for subsequent preheating type determination and pasting work, but the application system of the adhesive application mechanism 12 and the heating device 22 in this part is within the category of the existing technology. In addition, the structure design methods of the adhesive application mechanism 12 and the heating device 22 are many, and can be changed according to the actual application. Therefore, the present embodiment only describes a preferable example.
