[0035] Need to explain: through the design of glue outlet 28, the glue can uniformly flow out and cover on gluing upper roller 4, which reduces the waste of glue and improves the utilization rate of glue.

[0036] Please refer toFigure 5 The utility model provides a technical scheme: a double -sided gluing machine, including the inside lateral wall of glue box 26 is equipped with the glue inlet 27, the inner wall fixedly connected with glue pipe 22 of glue inlet 27, the one end fixedly connected with screw pump 29 of glue pipe 22 far from glue inlet 27, screw pump 29 is fixedly installed in the inner wall bottom end of support plate 2.

[0038] Please refer to Figure 5 The utility model provides a technical scheme: a double -sided gluing machine, including the inner wall of machine body 1 is equipped with glue pool 3, and glue pool 3 bottom fixed mounting has inclined plate 30.

[0039] Need to explain: the design of glue pool 3 can collect the excess glue of wood board in the process of gluing, avoids the random flow of glue in the machine interior or work area, keeps the neatness of working environment.

[0040] Please refer to Figure 5 The utility model provides a technical scheme: a double -sided gluing machine, including the material of inclined plate 30 is polytetrafluoroethylene, and the bottom of inclined plate 30 is provided with heating layer, and the end of inclined plate 30 near support plate 2 is lower than the end of machine body 1.

[0041] Need to explain: polytetrafluoroethylene is famous with its outstanding non - stick performance, this makes the glue not easy to remain on inclined plate 30, helps to keep the cleanliness of inclined plate 30, reduces maintenance cost;

[0042] Further, the design of bottom heating layer can uniformly heat inclined plate 30, improve the flowability of glue, promote the smooth flow of glue on inclined plate 30, so that more effectively gather in the bottom of gluing lower roller 18, also help to reduce the air bubble in glue, because heating can promote air bubble to rise and discharge, thereby improve the quality and efficiency of gluing;

[0043] Further, the layout of the end of inclined plate 30 near support plate 2 is lower than the end of machine body 1, is favorable to the natural flow of glue to gluing lower roller 18 under the action of gravity, and cooperates with the action of screw pump 29, forms effective glue circulation system, ensures the continuous supply and uniform coating of glue.

[0044] Please refer to Figure 1 The utility model provides a technical scheme: a double -sided gluing machine, including the material of gluing upper roller 4 and gluing lower roller 18 is silica gel, and the surface of silica gel is equipped with the groove for air bubble escape.

[0045] It should be noted that the silicone material has good elasticity and wear resistance, which enables the upper glue applying roller 4 and the lower glue applying roller 18 to maintain stable form and performance during long-term work, reducing the decline of glue applying quality caused by wear;

[0046] Further, the grooves on the surface of the silicone provide an escape channel for the bubbles. During the glue applying process, the bubbles in the glue will rise to the surface with the rotation of the upper glue applying roller 4 and the lower glue applying roller 18, and quickly escape through the grooves, thereby effectively reducing the residue of bubbles in the glue layer and improving the uniformity and quality of glue applying.

[0047] Working principle: pour glue into the bottom of the glue pool 3, and the glue will gather at the bottom of the lower glue applying roller 18 along the inclined direction of the inclined plate 30. At this time, start the screw pump 29, which will send the glue at the bottom along the glue pipe 22 through the glue inlet 27 into the inside of the glue box 26, and then flow out through the glue outlet 28. Synchronously start the motor 10 to drive the pinion gear one 9 to rotate, which will engage the gear wheel three 11 to drive the lower glue applying roller 18 to rotate, so that the glue covers the outer wall of the lower glue applying roller 18. The gear wheel three 11 will simultaneously engage the pinion gear two 20 to drive the gear wheel two 7 and the gear wheel one 5 to rotate, so that the upper glue applying roller 4 rolls and covers the surface with glue. At this time, insert the wooden board into the middle of the upper glue applying roller 4 and the lower glue applying roller 18. The rotation of the upper glue applying roller 4 and the lower glue applying roller 18 will drive the wooden board to move forward. At the same time, the glue on the surface of the upper glue applying roller 4 and the lower glue applying roller 18 is applied to the upper and lower surfaces of the wooden board. At the same time, the two surfaces of the wooden board contact the tooth tips of the lower bubble eliminating roller 13 and the upper bubble eliminating roller 14 during the forward movement, and drive them to rotate. During the rotation, the internal bubbles of the glue on the surface of the wooden board are treated by defoaming. During the continuous movement of the wooden board, the excess glue on the surface of the wooden board falls into the glue pool 3 for recycling. The device simultaneously defoams the internal bubbles of the glue during the glue applying process, avoids the existence of a large number of bubbles in the glue during the gluing process, and avoids the generation of gaps at the bonding position, thereby enhancing the bonding strength of the product and improving the glue applying efficiency.
