Description

Technical Field

[0001] The present application relates to the field of tobacco machinery, and more particularly to a paper powder scraping device for a web and a web feeding device including the paper powder scraping device. Background Art

[0002] The KDF4 fiber filter rod forming unit is a single-channel cigarette filter rod production equipment and is one of the filter rod production equipments with the highest automation and single-channel processing capacity in the world at present. The unit is composed of a fiber filter rod forming machine, a fiber loosening and gluing machine, a filter rod output device, a filter rod tray loading machine, and a web automatic conveying device. Among them, the forming cigarette gun channel is a key part of the fiber filter rod forming machine, and the cooling press strip on the forming cigarette gun channel is the core component of filter rod forming, which plays a crucial role in the quality of filter rod forming and directly affects the process quality of filter rods such as circumference, roundness, and appearance quality.

[0003] Figure 1 The process flow schematic diagram of the filter rod forming machine is shown, in which the web 1 is provided by an upstream web feeding device. First, the gluing device 2 sprays glue on the web 1. Specifically, the gluing device 2 sprays a strip of hot melt glue on the edge of the paper tape and sprays two cold glue lines on the left and right sides of the center of the paper running. A cloth belt is installed on the forming cigarette gun channel, and the tow 4 is sent to the running cloth belt by the wire feeder 3 and then wrapped by the web 1 with glue. After the filter rod is preliminarily formed, it enters the forming cigarette gun channel 5 and is quickly cooled and solidified by the cooling press strip 6 in the cigarette gun channel 5, and the filter rod is bonded and shaped into a strip and output. Then, the downstream breaking device 7 cuts off a part of the head of the filter rod, and successively passes through the diameter detection device 8 and the cutter head 9 to reach the receiving drum 10, where the cutter head 9 cuts the filter rod into a predetermined length.

[0004] During the forming process of the filter rod, the web 1 used often has paper powder on its two side surfaces. There are many reasons for the formation of paper powder. For example, due to the deficiencies of the web itself or different processing technologies and formulas of different brands, the paper powder will cause harm to the devices in the filter rod forming unit and thus affect the product quality. For example, when the web 1 with paper powder contacts the cooling press strip 6, it is easy for the paper powder to be adsorbed in a block on the working surface of the cooling press strip 6. After the equipment runs for a period of time, the position where the continuously accumulated paper powder is located will make the diameter of the formed filter rod smaller, directly affecting the forming quality of the filter rod.
