Description

A gypsum board edge sealing device

technical field

The invention relates to the field of gypsum boards, in particular to a water-wetting device for sealing edges of gypsum boards.

Background technique

Gypsum board is a material made of building gypsum as the main raw material. It is a kind of building material with light weight, high strength, thin thickness, convenient processing, sound insulation, heat insulation and fire resistance. Gypsum board has been widely used in interior partition walls, wall cladding panels, ceilings, sound-absorbing panels, ground base panels and various decorative panels of various buildings such as residences, office buildings, shops, hotels and industrial plants. should not be installed in the bathroom or kitchen. The lightweight partition wall composed of gypsum sheets or hollow gypsum strips can be used to separate indoor spaces, and has the characteristics of simple structure and easy processing and installation. This kind of partition wall usually uses steel and wood keel as the skeleton, and can be combined with other materials to form a partition wall with sound insulation, waterproof or advanced decoration requirements according to the requirements of use.

Gypsum boards mainly include paper gypsum boards, paperless gypsum boards, decorative gypsum boards, gypsum hollow strips, fiber gypsum boards, gypsum sound-absorbing boards, gypsum boards for positioning points, etc. In addition to traditional gypsum boards, new products are constantly being added, such as gypsum sound-absorbing boards, refractory boards, thermal insulation boards and gypsum composite boards. The specifications of gypsum board are also developing in the direction of high thickness and large size. In addition, the use of gypsum products is also expanding, in addition to being used as a base lining, it is also used as a surface decoration material, and even used as floor tiles, exterior wall substrates and wall core materials.

In the production process of gypsum board, the gypsum board is exposed at both ends of the gypsum board, which is easy to cause gypsum particles to fall off during transportation and affect the appearance quality of the gypsum board. Therefore, it is necessary to seal both ends of the gypsum board, that is, edge sealing. At present, the edge sealing tape needs to be wetted with water before it can be bonded to the gypsum board, so it is necessary to use the edge sealing watering device.

The existing edge-sealing and water-wetting device for gypsum board usually uses a roller to drive the edge-sealing belt and squeeze it with a sponge roller with water for water-wetting, and then use the edge-sealing device to seal the edge.

However, the existing gypsum board edge sealing device has the following defects:

(1) Using the sponge roller with water to squeeze and soak with water is easy to make the sponge lose its elasticity after repeated use, which makes the effect of soaking water worse and affects the bonding of the edge band;

(2) When the existing edge sealing device is wetted with water, it is easy to cause the edge sealing tape to wrinkle after being wetted with water, which affects the edge sealing quality of the gypsum board;

(3) Most of the structures of the existing edge-sealing water-wetting devices are fixed, but in actual use, depending on the different edge-sealing belts and the different requirements for the amount of water wetting, it is sometimes necessary to adjust the various structures of the device. Some devices cannot easily do this.
