干法纸生产线上设有热风箱,热风箱的作用是将加热风送到纸面网带上将纸页加热烘干。由于进来的热风比较大,分布不均匀,可将未热熔的纸幅吹散、吹变形,甚至无法让纸进入到热风箱里。因此,采用在热风箱的上部设有上下两层匀风板,用于均匀进来的热风,同时降低风的强度,使纸张顺利进入热风箱中。但是由于循环的热风带有粉尘,粉尘会将匀风板的孔堵死,造成无法正常生产。在此,提供一种热风箱防堵刮板机构。该热风箱防堵刮板机构将堆积在匀风板上的粉尘及时刮掉,以
Dry paper production line with a hot air box, hot air box is the role of the wind sent to the paper web with paper heating and drying. Due to the hot air coming in relatively large, uneven distribution, can be non-hot melt blown paper, blowing deformation, and even can not get the paper into the hot air box. Therefore, the upper part of the hot air box is provided with two uniform air baffles for even incoming hot air, meanwhile, the strength of the air is reduced so that the paper smoothly enters the hot air box. However, due to the circulation of hot air with dust, dust will be even wind plate hole blocked, resulting in normal production. Here, a hot air box anti-blocking scraper mechanism is provided. The hot air box anti-blocking scraper mechanism will be stacked on the wind plate dust scraped off in time
