Description

A glue applicator for gypsum board

technical field

The utility model relates to the field of equipment for making gypsum boards, in particular to a gluing device for gypsum boards.

Background technique

Gypsum board is made of building gypsum as the main raw material, mixed with appropriate amount of additives and fibers as the core of the board, and made of special cardboard as the protective surface. It is widely used in construction, industrial production and other industries.

In the process of making gypsum board, cardboard needs to be adhered to both sides of the board core as a protective surface, and the board needs to be glued before it can be adhered to the board core. At present, most of the existing gluing machines use rotating gluing rollers. The glue is sprinkled on the gluing roller or a sponge is built into the gluing roller for soaking the glue, and then the glue is applied to the surface of the gypsum board with the gluing roller. . However, due to the large length of the glue roller, it is difficult for the glue on the glue roller to disperse quickly, and there will be a phenomenon of uneven distribution of glue, resulting in uneven application on the gypsum board. In view of this, the prior art CN209303102U discloses a high-efficiency wheel-type glue applicator for the production of environmentally friendly gypsum boards, which includes a conveying table and a gluing device arranged above the conveying platform. The glue is evenly coated on the glue roller, the glue roller is arranged above the conveying table, the glue squeeze roller is arranged in parallel and diagonally above the glue roller, and between the glue roller and the glue roller. A first gap is formed, a glue storage bucket is arranged above the glue roller wheel, a glue outlet is arranged on the glue storage bucket, the glue outlet is located above the first gap, and the glue storage bucket is connected with a first drive for driving its reciprocating motion device. The gluing device is used in the veneer process of the gypsum board production process. First, apply glue on the surface of the gypsum board, and add a squeezing roller to cooperate with the gluing roller, so that the glue can be evenly coated on the surface of the gluing roller. In order to ensure that the glue roller can evenly apply the glue on the surface of the gypsum board to solve the problem of uneven application of glue on the gypsum board.

However, first apply glue on the surface of the gypsum board. Because the amount of glue is difficult to control, it is easy to cause too much or too little. If it is too much, it will cause waste of glue and increase the cost. If it is too small, the amount of glue is insufficient.

Utility model content

The purpose of the utility model is to provide a gluing device to solve the problem that the gluing device in the prior art cannot apply gluing on both sides and the gluing is not uniform.

The utility model relates to a glue applicator for gypsum board, comprising a conveying table, a glue tank, a frame body and a glue inlet pipe connected with the glue tank, wherein the glue tank is located on the top of the frame body; the conveying table includes A frame, a motor, a transmission chain and several conveying rollers, the conveying chain is located in the frame and is connected with the conveying roller to drive the conveying roller to rotate towards the same side, and at least two lower brushes are arranged at the end of the conveying table in the conveying direction The rubber roller, the size of the lower brush rubber roller is consistent with the size of the conveying roller; the frame body is located above the lower brush rubber roller and is fixed on the frame, and the frame body is opposite to the lower brush rubber roller. The upper brushing rubber roller, only a gypsum board passes between the lower brushing rubber roller and the upper brushing rubber roller, the lower brushing rubber roller and the upper brushing rubber roller are both connected with the rubber feeding pipe, the lower brushing rubber roller and the The upper brushing rubber roller is provided with a flexible glue outlet for the glue to flow out.

In the gluing device of the utility model, the glue tank is arranged on the top, and under the action of gravity, it flows to the lower rubber brushing roller and the upper brushing rubber roller through the rubber feeding pipe. There is a flexible glue outlet for the glue to flow out, so when the gypsum board to be glued is driven by the motor to drive the conveying roller to rotate, and then drive the gypsum board to drive, the gypsum board is transported between the lower brushing roller and the upper brushing roller. In the gap, under the extrusion of gravity and contact force, the glue on the lower brush rubber roller and the upper brush rubber roller flows into the gypsum board. Since the conveying table continues to convey, the lower brush rubber roller and the upper brush rubber roller can be Apply glue while transporting the gypsum board to ensure that the glue is applied evenly.

In the glue brushing device of the utility model, a part of the conveying roller is changed into a lower rubber brushing roller, and the upper part of the lower brushing rubber roller is matched with the same upper brushing rubber roller. When the gypsum board passes between the lower brushing rubber roller and the upper brushing rubber roller When there is a gap, under the action of gravity and extrusion force, the glue in the glue tank flows smoothly to both sides of the gypsum board, and the glue is brushed while conveying, and the glue is evenly coated on the gypsum board. As far as the prior art is concerned, it not only reduces the glue brushing time, but also ensures the uniformity of the glue brushing and avoids the waste of glue.

Further, the outer parts of the upper and lower rubber brushing rollers are sponges, and the interiors of the upper and lower rubber brushing rollers are rubber storage cylinders with a number of glue outlet holes. are connected to the inlet hose. The setting of the sponge body can make the brushing glue more uniform.

Further, the number of the upper brushing rubber roller and the lower brushing rubber roller is three.

Further, a vertical lifting groove is provided on the frame body, a tripod is rotatably connected to the end of the upper brush rubber roller, and a limit rod that is slidably connected to the lifting groove is fixedly connected to the tripod. The threaded connection is provided with a limit nut for fixing the tripod on the lifting groove. The three upper brush rubber rollers are connected by a tripod, and a limit rod is set on the tripod and fixed with a limit nut, so that the tripod is limited to a certain position of the lifting groove, and the upper brush rubber roller and lower brush can be adjusted according to the thickness of the gypsum board. The gap between the rubber rollers to select the most suitable gap for brushing.

Further, the bottom of the lower brushing rubber roller is provided with a gluing groove. There is glue flowing out of the lower brush rubber roller when it is squeezed, so a glue groove is set at the bottom of the lower brush rubber roller.
