The design of the glue collecting chamber helps to concentrate the glue liquid, and the grid plate 411 can further refine the glue liquid so that it is more evenly distributed on the first layer or the first layer, thereby improving the uniformity of glue spraying; the glue liquid is refined so that it is more evenly distributed on the material, thereby improving the glue spraying effect.

[0046] During glue spraying, the material is first transported and positioned, and the material is transported by the glue spraying conveying device 42. After the material is transported to the top of the glue spraying head 47, the glue dispensing box 46 is driven to the corresponding height by the lifting drive device; during glue spraying, the colloid pump pumps the glue liquid to make the glue liquid flow out from the glue spraying hole of the glue spraying head 47 and form a thick glue line, and then after passing through the glue collecting cavity of the guide head 410 and the grid plate 411 in the glue collecting cavity and being converged and uniformed, the glue line becomes a uniform glue curtain, and then the glue curtain is lowered to the first layer of board or the first layer of board by the lifting drive device; at the same time, the colloid pump is used to prevent the glue liquid from continuing to flow downward, and the glue liquid is collected by the receiving hopper 491 and the collecting bin 48 and filtered and reused.

[0047] Example 3 On the basis of Example 1 or Example 2, further, a rotating rod and a shock absorbing assembly are arranged on the lower side of the first mounting frame 15, and the shock absorbing assembly includes a bushing, a guide rod, a shock absorbing spring and a spring seat, and the spring seat is fixedly installed on the first mounting frame 15, the first roller 16 is connected to the end of the rotating rod, the bushing is sleeved in the middle of the rotating rod, the guide rod is fixed on the bushing, the shock absorbing spring is sleeved outside the guide rod and the upper end is connected to the spring seat, and the upper end of the shock absorbing spring is connected to the spring seat, which effectively reduces the vibration during the movement and improves the stability and service life of the equipment.

[0048] Furthermore, the rotating rods are arranged symmetrically front and back about the first mounting frame 15, and the shock absorbing components are arranged symmetrically left and right on each rotating rod, which further enhances the shock absorbing effect and improves the stability and reliability of the equipment.
