Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a paper surface dust removal device. Background Art

[0002] The filter rod forming unit consists of an opener, a forming machine and a tray loading machine, which completes the process from opening the tow to loading the filter rod and then to the filter rod forming process. The function of the forming machine is to wrap the acetate fiber tow belt processed by the opener with forming paper, cut it according to the specified requirements, and then transport it to the tray loading machine for loading. In this process, the forming paper is very important. The forming paper comes from the auxiliary material supplier upstream of the cigarette factory. At present, most manufacturers use calcium carbonate. On each conveying path through which the forming paper passes, there are various paper guide rollers, pressing rods, pressing plates and smoke gun channels. The calcium carbonate and short fibers in the forming paper will produce paper powder and fall down under the action of friction. The subsequent filter rod will affect the ventilation rate of the entire cigarette after the winding process, affecting the product quality (the main function of ventilation is to reduce tar and reduce harm. A good ventilation rate can ensure the stability of various indicators such as the tar content of the cigarette). At the same time, paper powder will continue to accumulate on the equipment as the forming machine runs, and it needs to be frequently noticed and stopped for cleaning. Severe accumulation will cause the equipment to stop, affecting the equipment's operating efficiency. Utility Model Content
