Description

Technical Field

[0001] The utility model relates to the field of multi-layer flame-retardant board production, in particular to a gluing device for the production of multi-layer flame-retardant boards. Background Art

[0002] Flame retardant board, also known as flame-retardant board, flame-retardant plywood, flame-retardant plywood, etc., is a three-layer or multi-layer plywood made by peeling logs into wood chips or planing wood blocks into small wooden blocks, treating the wood chips with flame retardant treatment and then gluing them with adhesives, so that the fiber directions of adjacent layers of wood chips are perpendicular to each other. When gluing manually, the gluing operation is cumbersome, resulting in uneven gluing and waste of glue.

[0003] A Chinese patent application numbered CN201721641757.4 discloses a gluing device for the production of multi-layer flame-retardant panels, which solves the problems of manual gluing. However, the device requires the user to push the gluing mechanism to apply glue to the surface of the flame-retardant panel. Since it is manually pushed, there is inevitably the problem of unstable pushing speed. When the gluing speed remains unchanged, pushing too fast will cause the glue to be too thin, and pushing too slow will cause the glue to be too late, so the device still has the problem of uneven gluing.

[0004] A Chinese patent search shows a gluing device for producing multi-layer flame retardant panels (publication number CN210453090U), which includes two mounting rods, a conveyor belt is installed between the two mounting rods, a support rod is fixedly connected to the upper side of the mounting rod, a gluing mechanism is slidably installed between the two support rods, the gluing mechanism includes a glue storage box and a gluing roller arranged below the glue storage box, both ends of the gluing roller are rotatably connected to a fixed frame, the ends of the two fixed frames away from the gluing roller are fixedly connected to the glue storage box, a cross bar is fixedly connected above the support rod, and a mounting groove is provided inside the cross bar. The utility model sets a mesh plate at the glue outlet to make the glue storage box more uniform in glue discharge, cooperates with the conveyor belt to drive the flame retardant panel to move at a uniform speed, so that the gluing roller evenly applies the glue on the surface of the flame retardant panel, and avoids the relative speed between the glue outlet and the flame retardant panel being too fast, resulting in too thin glue coating, or the relative speed between the two being too slow, resulting in too thick glue coating.

[0005] Although the above patent improves the uniformity of glue coating, the flame retardant board is not dusted before gluing, so that the dust attached to the flame retardant board will affect the subsequent gluing effect.

[0006] Therefore, it is necessary to invent a glue application device for producing multi-layer flame retardant panels to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a gluing device for producing multi-layer flame retardant boards, so as to solve the problem that dust attached to the flame retardant boards will affect the subsequent gluing effect proposed in the above background technology.

In addition, when the staff observes through the visual glass that the glue liquid inside the glue delivery box is insufficient, the glue delivery pump can be started. The glue delivery pump delivers the glue liquid inside the glue storage box to the inside of the glue delivery box through the fourth transmission pipe and the third transmission pipe, which is convenient for the staff to add glue liquid.
