Filter stick material pre-folding and collecting device

Abstract

The filter stick material pre-folding and collecting device comprises a rack, a paper guide device, a conical barrel, a first-stage forming wheel and a second-stage forming wheel are sequentially installed on the rack from upstream to downstream, a paper guide channel is formed in the paper guide device, and the paper guide channel is gradually shrunk from the inlet end to the outlet end; a conical channel is formed in the conical barrel, the large opening end of the conical channel faces the paper guide device, and the small opening end of the conical channel faces the first-stage forming wheel; the first-stage forming wheel and the second-stage forming wheel are each composed of a fixed wheel and a separation wheel, the distance between the fixed wheels and the separation wheels is the wheel distance, the wheel distance of the first-stage forming wheel is larger than the wheel distance of the second-stage forming wheel, and the diameter of the small opening end of the conical channel is larger than the wheel distance of the first-stage forming wheel. The first-stage forming wheel and the second-stage forming wheel are driven by a power device to rotate. The bundling device can enable the end face hole of the cooling base rod to meet the technological standard, the roundness index meets the technological standard, and the cigarette rejecting amount is reduced by more than 50%.

Description

technical field [0001] The present invention relates to a filter rod processing tool, more specifically, the present invention relates to a filter rod material pre-folding device Background technique [0002] Looking at the international tobacco market, heating cigarettes, as typical categories of new tobacco products, are rapidly emerging. Because of their low harm and taste closer to traditional cigarettes, they are well received by consumers and have great development potential. Heated cigarettes mostly adopt four-section structure, which are respectively composed of a smoking section (aerosol forming matrix), an empty tube section (supporting element), a cooling section (cooling), and an acetate fiber section (filtering). The base rod of the cooling section is processed Polylactic acid film bending and wrinkling treatment schemes are mostly used. [0003] ZL22 filter rod forming machine is still the mainstream model of domestic cigarette filter base rod production equip...

Problems solved by technology

[0010] The present invention overcomes the deficiencies of the prior art, and provides an embodiment of a filter rod material pre-folding and converging device, in order to solve the quality problems of the cooling base rod with excessively large end surface pores (>1mm) and ultra-high roundness index. And the roundness of the cooling base rod exceeds the standard, which leads to great difficulty in downstream machine processing, resulting in appearance quality defects (wrinkles and bubbles), many cigarettes, resulting in quality problems such as unqualified appearance inspection of cigarettes
