Description

Glue applying device and glue applying system

Technical Field

The utility model relates to the technical field of plate production equipment, in particular to a glue applying device and a glue applying system.

Background

The glue applying device for the edge glue of the existing paper-surface gypsum board adopts a form of a glue applying pipe, the output end of the glue applying pipe is connected with a glue applying nozzle, and glue flows out through the glue applying nozzle and then is adhered to the surface of a sample to be applied with glue. Generally, the size of the glue applying nozzle needs to be designed to be as small as possible, so that waste of raw materials caused by too large width of a glue applying area can be avoided, and moreover, the phenomenon of glue overflow of the edge of the board caused by excessive glue applying can be avoided, so that the attractiveness of the edge of the board is not affected.

Because the glue often has certain viscosity, the glue can harden and agglomerate after a period of time when adhering to the inner wall of the glue applying nozzle so as to block the glue applying nozzle, so that the glue on the surface of the glued plate is uneven, and the product percent of pass is reduced.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

In some exemplary embodiments, as shown in FIG. 3, applicator roll 11 is generally configured as a cylinder or disk for the purpose of providing a continuous sizing area, and the cross-sectional shape of first applicator surface 111 on applicator roll 11 is circular. Before the sizing operation, the applicator roll 11 is arranged to be in contact with the surface of a sample to be sized in a part of area, and the first sizing surface 111 arranged on the rim of the applicator roll 11 is immersed in the glue solution of the sizing box 14; when the sample to be sized and the applicator roll 11 move relatively, the glue solution stored on the glue storage structure 112 of the applicator roll 11 adheres to the surface of the sample to be sized along with the rotation of the applicator roll 11, and the sizing operation is finished.

In some exemplary embodiments, the applicator roller 11 may not be provided with a separate driving device, and the applicator roller 11 may rotate around one end of the bracket 13 under the driving of the application sample transmission; in some exemplary embodiments, in order to increase the speed of application, a separate drive is provided for applicator roll 11 to increase the speed of relative movement of applicator roll 11 and the sample to be sized.

In some exemplary embodiments, in order to apply glue to a predetermined area, i.e., to obtain a discontinuous glue application area, applicator roll 11 may be configured with an irregular cross-sectional shape, i.e., the first glue application surface 111 on applicator roll 11 is in non-continuous contact with the surface of the sample to be sized; applicator roll 11 may be gear-shaped, cam-shaped, or a specific curved shape, etc.
