与现有技术相比,本发明具备以下有益效果:Compared with the prior art, the present invention has the following beneficial effects:
1、本发明在抽风机的工作下,外部空气通过风罩上的进风口经过滤网进入风罩内,过滤网阻止外界环境中的灰尘进入风罩内,避免对基材和贴面材料造成灰尘污染。1. In the present invention, under the operation of the exhaust fan, the external air enters the air hood through the air inlet on the air hood through the filter screen, and the filter screen prevents the dust in the external environment from entering the air hood, so as to avoid causing damage to the base material and the veneer material. Dust pollution.
2、本发明中过滤后的空气再经过导流风道吹向两个芯轴上转动连接的除尘环和多个刷头,在此过程中,风力在对基材和贴面材料形成吹动除尘,同时驱动除尘环和多个刷头转动对基材和贴面材料表面进行清扫除尘。2. In the present invention, the filtered air is blown to the dust-removing rings and a plurality of brush heads rotatably connected on the two mandrels through the guide air duct. During this process, the wind blows the base material and the veneer material. To remove dust, simultaneously drive the dust removal ring and multiple brush heads to rotate to clean and dedust the surface of the base material and the veneer material.
3、本发明中刷头随除尘环转动时,由于芯轴内部磁块磁极位于芯轴底部靠近基材传来方向一端,刷头在刚与基材挤压接触转动到磁块磁极轴向时,感应线圈内的磁通量逐渐加快变大,进而产生同向的感生电动势,使刷头带上同种电荷,对小颗粒灰尘形成静电吸引,使灰尘被刷头带离基材表面,在刷头继续转动后,感应线圈内的磁通量逐渐减小直至近似不变,此时灰尘被刷头抛洒出来,进而被气流带走,完成整个除尘操作。3. In the present invention, when the brush head rotates with the dust removal ring, since the magnetic pole of the magnetic block inside the mandrel is located at the bottom of the mandrel near the end of the transmission direction of the base material, when the brush head is just in contact with the base material and rotates to the axial direction of the magnetic pole of the magnetic block , the magnetic flux in the induction coil gradually accelerates and becomes larger, thereby generating the induced electromotive force in the same direction, so that the brush head is charged with the same charge, forming electrostatic attraction to small particles of dust, so that the dust is carried away from the surface of the substrate by the brush head. After the head continues to rotate, the magnetic flux in the induction coil gradually decreases until it is approximately constant. At this time, the dust is thrown out by the brush head, and then carried away by the airflow to complete the entire dust removal operation.
综上,本发明一方面利用风力驱动除尘环和刷头转动,形成风力吹动和刷头清扫相配合的除尘效果,同时可以达到持续除尘的目的,另一方面通过刷头转动过程中携带同种电荷对小颗粒灰尘产生静电吸引再将其抛洒至气流中,提高了除尘效果,同时避免刷头内粘附灰尘。To sum up, on the one hand, the present invention uses the wind to drive the dust removal ring and the brush head to rotate to form a dust removal effect that combines wind blowing and brush head cleaning, and at the same time can achieve the purpose of continuous dust removal. This kind of electric charge produces electrostatic attraction to small particles of dust and then throws it into the airflow, which improves the dust removal effect and prevents dust from adhering to the brush head.
