Due to the defects of the existing glue dispensing device, if the glue is not smooth, it will affect the bonding quality of the bottom plate and the core material; especially for the production of V-groove composite panels, its shortcomings are more obvious
as in the accompanying drawings figure 1 As shown, the structure schematic diagram of the existing dispensing device when dispensing glue to the V-groove composite plate bottom plate is given. Since the diameter of the dispensing hole on the existing dispensing pipe is small, generally about 0.8mm, the dispensing hole is very easy. It is blocked by impurities, and 1 to 2 dispensing holes do not drip glue, especially when producing V-groove composite boards, because the board surface is divided into several grooves by some V-shaped protrusions, if the top of a certain groove If there is no glue in the glue hole, there will be no glue in one or several grooves, which will seriously affect the bonding effect of the core material.

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 As shown, a schematic diagram of the structure of the existing glue pipe and the bottom plate of the V-groove composite plate is provided. The glue pipe 1 is provided with a number of glue holes 2, and the diameter of the glue hole 2 is about 0.8mm. The glue used to bond the core material of the composite board and the base plate flows into the glue dripping pipe 1, overflows from the glue dripping hole 2, and finally drips onto the base plate of the composite board. Since the dispensing hole 2 on the dispensing pipe 1 is very small, it is easy to be blocked by impurities, and 1 to 2 dispensing holes do not drip glue, especially when producing V-groove composite boards, because the board surface is covered by some V Type protrusion 4 is separated into several grooves, if glue dripping hole 2 above a certain groove does not drip ...

The invention relates to a glue dripping device for building composite plates. The glue dripping device comprises a glue dripping tube connected with a glue supply system, and a plurality of glue dripping holes for glue to flow out are arranged on the glue dripping tube. The glue dripping device is characterized in that a flow distribution groove is arranged along the axis direction of the glue dripping tube, an opening of the flow distribution groove faces towards the glue dripping tube, and a plurality of secondary glue dripping holes for dripping the glue are arranged at the bottom of the flow distribution groove. The aperture of each secondary glue dripping hole is larger than that of each glue dripping hole. Flow of the glue is distributed by the glue dripping device for building composite plates, so that the glue can be uniformly coated on a bottom plate assuredly. Even if the glue dripping holes on the glue dripping tube are blocked, glue can be reserved between each two adjacent V-shaped bumps. The glue dripping device has the advantages of simple structure, high beneficial effects and convenience in popularization and application.
Description
technical field [0001] The invention relates to a glue dispensing device for building composite boards, more specifically, to a glue dispensing device for building composite boards used in the production process of V-groove composite boards. Background technique [0002] In the production process of building composite panels, in order to make the core material and the base plate firmly bonded together, it is necessary to apply a layer of glue on the base plate with a glue dropping device. Due to the defects of the existing glue dispensing device, if the glue is not released smoothly, it will affect the bonding quality of the bottom plate and the core material; especially for the production of V-groove composite panels, its shortcomings are more obvious. as in the accompanying drawings figure 1 As shown, the structure schematic diagram of the existing dispensing device when dispensing glue to the V-groove composite plate bottom plate is given. Since the diameter of the dispe...
