Description

Panel adhesion and foaming liquid of injection apparatus for construction}

The present invention relates to a foam liquid spray device for bonding a building panel, and more particularly, in order to pad a steel sheet member formed to have an uneven curved cross section by a roll forming unit having a plurality of rollers having different cross sections on both sides of a styropole. Two different types of adhesive foaming liquid sprayed to the steel sheet member are sprayed through one spraying nozzle in a completely mixed state, so that the failure rate of panel manufacturing can be minimized. It is about.

As is well known, building panels are widely used as roof or wall boards in factories, warehouses, prefabricated buildings, etc. in various forms.

The building panel 10 is a steel sheet member 14 formed by a roll forming machine having a plurality of rollers having different cross-sectional shapes on both sides of the styropole 12, which is sound insulation and heat insulating material, as shown in FIG. 16 is padded and pressurized to be manufactured continuously.

The panel 10 is continuously manufactured through the building panel manufacturing line 20 installed in the room maintaining a constant room temperature. Looking at this, as shown in FIG. While moving while being molded into the outer steel sheet member 14 while passing through the outer roll forming unit 22 provided with a plurality of rollers 22a having different cross sections, a styropole ( 12) The liquid is sprayed through the spray nozzle 24a for the PPG BLENDS liquid (Polypropyleneglycol compound) and the spray nozzle 24b for the C-MDI liquid (Polyethylene polyphenyldiisocyanate) provided in the spraying unit 24 for adhesive foaming. It is done.

The liquid injected through the injection nozzles 24a and 24b of the injection unit 24 passes the vibrating unit 26 provided at the rear end of the injection unit 24 while moving the liquid to the steel sheet member 14. ), And then, the styropole 12 provided from the styropole storage unit 28 moves while being seated on the upper surface of the outer steel sheet member 14 being transferred.

As described above, the inner steel sheet member 16 that is padded on the upper surface of the styropole 12 seated on the upper surface of the outer steel sheet member 14 to form the inner surface of the panel 10 passes through the inner molding part 30. When it is molded and moved, the PPG BLENDS liquid and the C-MDI liquid are injected through the injection nozzles 32a and 32b provided in the injection unit 32 like the outer steel sheet member 12 described above.

Subsequently, the liquid is moved while being mixed on the inner steel sheet member 16 while moving through the vibrating portion 34 provided at the rear end of the spraying portion 32 to be attached to the upper surface of the outer steel sheet member 14. The top surface of the styropole 12 is padded.

Thereafter, it is provided to be movable by hydraulic pressure, and is moved to the pressurizing part 36 provided with a plurality of rotatable pressure rollers 36a on one side thereof, and is cut to a predetermined size through the cutting part 38 while being pressurized. It is made of panel (10).

On the other hand, such a manufacturing apparatus is configured to be able to manufacture a variety of panels, as shown in Figure 2 is another example of the uneven bent cross-section in the rear end of the roll forming machine 22 of the outer steel sheet member 14 An outer roll forming machine 42 equipped with a plurality of rollers 42a is formed to form a small formed outer steel sheet member 40, and at the rear end thereof, the above-mentioned PPG BLENDS liquid and C-MDI liquid are respectively sprayed. The liquid injection unit 24 is installed in a state of moving downwards, and a vibration unit 26 for mixing according to the liquid injection is installed.

Therefore, when the outer steel sheet member 14 having a large uneven curved cross section is to be molded, the steel sheet member is molded through the roll forming machine 22 shown on the right side of FIG. 2, and the outer steel sheet having a smaller uneven curved cross section is formed. When the member 40 is to be molded, the steel sheet member 40 is formed by using the outer roll forming machine 42 installed at the lower end of the intermediate portion.

In this way, the building panel is made of PPG BLENDS liquid and C-MDI liquid sprayed through the spray nozzle of the liquid spraying part provided on the manufacturing line, and thus the inner and outer steel sheet members and the styropole are adhered to each other. As a result, a defective rate is generated according to panel manufacturing.

However, the liquid spraying unit installed in the above-described conventional building panel manufacturing line injects liquid through each spraying nozzle, and then mixes the liquid sprayed to the steel sheet member by the vibrating unit while passing through the vibrating unit. In the state that the mixing of the styropol is not made completely and the inner steel plate member is padded and pressurized, and then the panel is manufactured by cutting, so the failure rate of the panel due to poor adhesion with the styropol according to the panel manufacturing There was an increasing problem.

Accordingly, the present invention has been made in order to solve the above problems, the injection device to inject the liquid through a single injection nozzle in the state of mixing the Styropol PPG BLENDS liquid and C-MDI liquid on the manufacturing line The purpose of the present invention is to provide a foam liquid spraying device for building panel adhesion, which can reduce the defect rate according to panel production by minimizing adhesion failure with styropol according to panel manufacturing.
