[0024] like Figures 1 to 4As shown, a specific embodiment of the utility model provides a plywood gluing device, including a machine platform 101, on which a plurality of conveying rollers 104 for conveying plates are installed, and a plurality of supporting columns 102 are installed on the machine platform 101, and a top plate 103 is installed on the top of the supporting column 102, and a dust removal roller 301 and a glue coating roller 403 are sequentially arranged at the bottom of the top plate 103 along the plate movement direction, and the glue coating roller 403 is used to apply glue to the upper surface of the plate, and the dust removal roller 301 includes a plurality of dust whisk portions 302 arranged in an array along the axial direction of the roller body, and gaps are formed between adjacent dust whisk portions 302. A accommodating chamber 306 is provided inside the dust removal roller 301, and a plurality of negative pressure holes 303 are connected between the accommodating chamber 306 and the gap. A hollow shaft 304 and a power shaft 308 are fixedly connected at both ends of the dust removal roller 301, and the hollow shaft 304 and the power shaft 308 are rotatably connected with a mounting plate 202, respectively. The mounting plate 202 can be lifted and installed below the top plate 103. An airway shaft 305 connected to the accommodating chamber 306 is installed inside the hollow shaft 304, and the airway shaft 305 is connected to a gas pipeline 203, and the gas pipeline 203 is connected to a negative pressure pump for generating negative pressure in the accommodating chamber 306.

[0025] During use, the plate is placed on the conveying roller 104. Driven by the conveying roller 104, the plate moves forward and passes through the dust removal roller 301 and the glue coating roller 403 in turn. When the plate passes under the dust removal roller 301, the dust whisk 302 on the dust removal roller 301 rubs against the plate and lifts up the dust on the surface of the plate. The negative pressure pump is connected to the airway shaft 305, and the airway shaft 305 is connected to the accommodating chamber 306, so that negative pressure is generated inside the accommodating chamber 306, so that the negative pressure hole 303 absorbs the raised dust and the dust on the surface of the plate. The dust on the surface of the plate is effectively removed through the contact between the dust whisk 302 and the surface of the plate and the negative pressure absorption of the negative pressure hole 303. Then the plate moves to the glue coating roller 403 for gluing, which has a better gluing effect and a higher quality of the finished plywood.

[0026] In some optional specific embodiments, such as Figure 1 As shown, the end of the power shaft 308 passes through the rubber roller mounting plate 402 and is installed with a transmission wheel 204, on which a transmission belt 205 is installed, and the transmission belt 205 is connected to a driving pulley, and the driving pulley is connected to a driving motor, which is fixedly installed inside the machine 101. The dust removal roller 301 is driven to rotate by the driving motor, so that the movement speed of the dust removal roller 301 and the diameter of the plate are different, thereby more effectively removing dust from the surface of the plate.

[0027] In some optional specific embodiments, such as Figures 2 to 4As shown, the airway axis 305 is connected to a negative pressure generating tube 307, and a suction transverse hole 309 is opened in the lower part of the negative pressure generating tube 307 along the axial direction. During the rotation of the dust removal roller 301, the negative pressure generating tube 307 does not rotate with the dust removal roller 301, and the suction transverse hole 309 always faces the upper surface of the plate, so that the negative pressure hole 303 on the dust removal roller 301 has a large suction force toward the plate surface and a small suction force away from the plate. When the whisk part 302 contacts the upper surface of the plate, the dust is lifted up and is sucked and captured by the negative pressure hole 303 facing the plate, and a small amount of dust that escapes into the air is sucked by the negative pressure hole 303 away from the plate.

[0028] In some optional specific embodiments, such as Figure 1 As shown, an electric telescopic rod 201 is installed between the top of the mounting plate 202 and the bottom of the top plate 103, which is used to adjust the distance between the dust removal roller 301 and the upper surface of the plate.

[0029] In some optional specific embodiments, such as Figure 1 As shown, a gluing telescopic rod 401 is installed between the top of the gluing roller mounting plate 402 and the bottom surface of the machine top plate 103, which is used to adjust the distance between the gluing roller 403 and the upper surface of the plate.

[0030] In some optional specific embodiments, the whisk part 302 is made of sponge material.

[0031] In some optional specific embodiments, a conveyor pulley is installed at the end of the conveyor roller 104, and multiple sets of conveyor pulleys are connected and driven by conveyor belts. The conveyor pulley power is connected to a conveying motor, and the conveying motor drives the multiple sets of conveyor rollers 104 to rotate.

[0032] In some optional specific embodiments, such as Figure 2 As shown, the hollow shaft 304 is connected to the airway shaft 305 via a sealed bearing, which ensures the rotation of the hollow shaft 304 relative to the airway shaft 305 and at the same time ensures sealing to a certain extent.

[0033] The working principle of the utility model is as follows: during use, the plate is placed on the conveying roller 104. Driven by the conveying roller 104, the plate moves forward and passes through the dust removal roller 301 and the glue coating roller 403 in turn. When the plate passes under the dust removal roller 301, the dust whisk 302 on the dust removal roller 301 rubs against the plate and takes away and lifts up the dust on the surface of the plate. The negative pressure pump is connected to the airway shaft 305, and the airway shaft 305 is connected to the accommodating chamber 306, so that negative pressure is generated inside the accommodating chamber 306, so that the negative pressure hole 303 absorbs the raised dust and the dust on the surface of the plate. Through the contact between the dust whisk 302 and the surface of the plate and the negative pressure absorption of the negative pressure hole 303, the dust on the surface of the plate is effectively removed, and then the plate moves to the glue coating roller 403 for gluing, the gluing effect is better, and the quality of the finished plywood is higher.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
