Problems solved by technology

[0003] This method has many disadvantages, such as large air bubbles on the upper paper due to more floating bubbles in the slurry, non-sticking of layers, excessive fire on the side of the upper paper, and low transverse strength of the gypsum board, resulting in lower unit weight. The drywall is of poor quality

Embodiment 1

[0028] The paper hard surface equipment of the gypsum board that the embodiment of the present invention provides, such as Figure 1 to Figure 3 As shown, it includes: a frame body 100; an applicator roller 200, which is rotatably mounted horizontally on the frame body 100, and is used for adhering the slurry 900 and rolling the adhering slurry 900 on the underside of the upper paper 300 On the paper; and a defoaming device 400, which is arranged on the side of the applicator roller 200, and is used to defoam the slurry 900 that is rolled.

[0029] The paper hard surface equipment for gypsum board, the application roller 200 is located above the slurry 600 and is in contact with the slurry 600, the upper paper 300 is located above the application roller 200 and is in contact with the application roller 200, and the application roller 200 rolls on the slurry 900 Adhesive slurry 900, and roll-coat the adhering slurry 900 on the lower side of the upper paper 300, and the defoamin...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is: as Figure 4 As shown, the defoaming device 400 faces the lower paper surface of the upper paper 300, and after the application roller 200 roll-coats the slurry 900 on the lower paper surface of the upper paper 300, the defoaming device 400 faces the lower paper surface of the upper paper 300. The defoaming of the slurry 900 rolled on the surface can also achieve the purpose of this application, and its purpose does not deviate from the design concept of the present invention, so it will not be repeated here, and should also belong to the protection scope of this application.

[0040]The paper hard surface method (not shown in the figure) of the paper hard surface equipment of the gypsum board includes: controlling the rolling of the application roller 200, making the roller surface of the application roller 200 adhere to the slurry 900 on the slurry 600, and The adhering slurry 900 is rolled onto the lower pap...

Embodiment 3

[0044] The gypsum board production line that the embodiment of the present invention provides, such as figure 1 , figure 2 and Figure 4 As shown, the paper hard surface equipment comprising the gypsum board described in any of the above-mentioned embodiments.

[0045] The lower unit weight gypsum board produced by this gypsum board production line forms a layer of basically no air bubbles, dense, good nail-holding force, and uniform gypsum slurry on the lower side of the upper paper 300, and the upper side of the gypsum board does not exist Paper 300 has problems such as large air bubbles, non-stick layers, excessive heat on the side of paper 300, low transverse strength of gypsum board, etc., and the quality is better.

[0046] For example, as figure 1 , figure 2 and Figure 4 As shown, the gypsum board production line also includes a tensioning device 700, a sizing device 800 and a forming platen 1100, and the tensioning wheel of the tensioning device 700 is pressed ...

Abstract

The invention discloses paper feeding and surface hardening equipment and a paper feeding and surface hardening method for a gypsum board and a gypsum board production line. The paper feeding and surface hardening equipment comprises a frame body; a smearing roller which is rotatably and transversely arranged on the frame body and is used for adhering slurry and coating the adhered slurry onto thelower side paper surface of upper paper in a rolling manner; and a defoaming device which is arranged beside the smearing roller and is used for defoaming the roll-coated slurry. According to the paper feeding and surface hardening equipment, the smearing roller is located above the slurry, the upper paper is located above the smearing roller, the smearing roller rolls on the slurry to adhere theslurry, the adhered slurry is roll-coated onto the lower side paper surface of the upper paper, and the defoaming device is used for defoaming the roll-coated slurry. A layer of gypsum slurry which is basically free of bubbles, compact, good in nail-holding power and uniform is formed on the lower side paper surface of the upper paper, the manufactured gypsum board with low piece weight does nothave the problems that the upper paper has large bubbles, layering is not sticky, the side edge of the upper paper is burnt, and the transverse strength of the gypsum board is low, and the quality ismade better.

Description

technical field [0001] The invention relates to the technical field of gypsum board production, and more specifically, relates to a paper hard surface equipment for gypsum boards, a gypsum board production line and a paper hard surface method for gypsum boards. Background technique [0002] During the development of gypsum boards, in order to reduce production costs, manufacturers have continuously reduced the unit weight (weight per unit area) of gypsum boards. The conventional method to reduce the single weight of gypsum board is to "increase the use of foaming agent and compressed air to make the pores of the gypsum board core larger and more". [0003] This method has many disadvantages, such as large air bubbles on the upper paper due to more floating bubbles in the slurry, non-sticking of layers, excessive fire on the side of the upper paper, and low transverse strength of the gypsum board, resulting in lower unit weight. The drywall is of poor quality. Contents of ...
