Description

Technical Field

[0001] The utility model relates to the technical field of wood board production, in particular to a uniform glue coating machine for wood board production. Background Art

[0002] Wood board production is a complex process involving multiple processing techniques, technical methods, and a wide range of applications. Wood board production not only meets the needs of industries such as construction and furniture, but also plays a significant role in improving wood utilization and protecting the environment. A wood board production uniform glue applicator is a device specifically designed to evenly apply adhesive to the surface of the wood during the production process. This machine is widely used in artificial board factories, furniture factories, and other production lines that require lamination of wood boards.

[0003] To this end, the patent with announcement number CN217190609U discloses a gluing machine for wood board processing, which belongs to the technical field of wood board processing. The gluing machine for wood board processing includes a machine body, two main glue rollers, a glue bucket, a control device and two auxiliary glue rollers. A support component is vertically fixedly installed on the upper surface of the machine body, and a gluing component is provided on each of the glue spokes. The gluing component includes two ear plates and a glue box. The glue box is horizontally fixedly installed on the side of the support component through two ear plates. A discharge port is horizontally opened on the bottom surface of the glue box on one side close to the main glue roll. There is a clearance fit between the main glue roller and the discharge port. The glue bucket is connected to the two glue boxes through a guide pipe. The end of the roller shaft is provided with a driving component;

[0004] The above-mentioned technical solution effectively solves the problem that the existing glue coating machine is prone to poor flow during the discharge process, which makes it impossible for the adhesive to evenly blend with the main glue roller, resulting in uneven coating. However, during the use of the above-mentioned glue coating machine, the glue flows out of the guide tube and drips onto the main glue roller. This situation requires a large amount of glue to cover the entire outer side of the main glue roller. This not only wastes the amount of glue, because the glue will flow on the main glue roller, resulting in a small amount of glue in some areas and a large amount in some areas. When the glue roller contacts the plate, there will be local accumulation of glue, which leads to uneven gluing of the plate. At the same time, the glue is not stirred in the above-mentioned document. After not being used for a long time, the glue is prone to sedimentation, affecting subsequent use, thereby reducing work efficiency. Utility Model Content
