Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery and equipment, in particular to a paper guiding mechanism for positioning tipping paper. Background Art

[0002] The appearance and quality of cigarettes are important symbols of the brand of cigarettes. The quality standard requires that the tolerance of the length of the tipping paper is ±0.5 mm. Market complaints about the quality defects of the tipping paper account for about 30%. During the production process of the PROTOS70 cigarette-making unit, the tipping paper needs to be conveyed, glued, and cut into single pieces of tipping paper before being wrapped on cigarettes and double-length filters. Due to the non-perpendicularity of the paper guide roller to the relative surface of the equipment body, the splicing of the tipping paper roll change, and the flatness of the auxiliary materials, the tipping paper is easily displaced, resulting in problems such as the length deviation and warping of the tipping paper. According to statistics, the average number of times the tipping paper is adjusted by the existing operating means is about 29 times / shift. Multiple adjustments are likely to affect product quality, causing cigarettes with slightly short tipping paper to flow into the next process. In addition, some deviations are too large, causing a large number of cigarettes to be rejected, and even cigarettes with one-sided tipping paper warping will flow into the market, affecting the operating efficiency of the equipment while increasing the consumption of auxiliary materials, and even causing market complaints.

[0003] The original PROTOS70 winder only has a paper guide block before the tipping paper is glued. After the tipping paper is glued and conveyed, its position relative to the center axis of the drum will be offset, and the position of the tipping paper needs to be adjusted frequently, which is inefficient and easily causes waste of auxiliary materials. Therefore, a special tool is needed to locate whether the tipping paper is centered. Summary of the invention

[0004] The utility model aims to overcome the deficiencies in the prior art and to provide a paper guiding mechanism for positioning the tipping paper. Before the tipping paper enters the paper cutting wheel, the paper guiding mechanism can be used to position the tipping paper in the center without deviation, thereby ensuring that the length of the tipping paper is consistent when double-length cigarettes are cut.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, a dovetail groove is provided at the bottom of the tipping paper guide block; the dovetail groove matches the size of the trapezoidal dovetail positioning block.

[0008] Furthermore, two positioning pin holes are provided at the bottom of the tipping paper guide block, and the positioning pin holes cooperate with the fastening screws.

[0009] Furthermore, a pair of U-shaped grooves are symmetrically arranged on the trapezoidal dovetail positioning block, and the relative position between the two U-shaped grooves is arranged correspondingly according to the relative position between the two positioning pin holes.
