The purpose is as follows: the problem of punch before the system is rolled up to the shaping paper that leads to the paper tube structure defect of current punching be difficult to guarantee to beat the mutual coincidence of ventilation hole on the shaping paper in advance, influence the ventilation rate of paper tube, and then lead to the ventilation rate difference between each paper tube big, the ventilation rate is unstable is solved.
Description
Technical Field
The utility model belongs to the technical field of heating cigarette, concretely relates to porous paper tube for heating cigarette holder stick.
Background
The heating cigarette is a novel tobacco product which heats tobacco by using a special heat source (below 500 ℃ or even lower) but is not combusted, and is characterized in that harmful ingredients generated by combustion in the traditional cigarette are reduced, and simultaneously, the satisfaction of nicotine and the feeling of tobacco fragrance characteristics can be provided for consumers. The cigarette has high water content and short smoke passage, so that the sensory temperature of the mainstream smoke reaching the oral cavity is higher than that of the traditional cigarette. At present, the paper tube used in the industry is used for heating the cigarette composite filter tip, the circulation process of smoke is naturally cooled, and the paper tube is used in combination with an air vent, so that the smoke cooling rate can be further increased, and the comfort level of inlet smoke is improved.
The existing spiral forming paper tube is fully covered by a plurality of layers of forming paper spirals, and in the manufacturing process, the forming paper can only be punched after being rolled into a cylindrical shape; if the holes are punched before the paper tubes are made by winding the paper tubes with the molding paper, the mutual overlapping and ventilation of the ventilation holes on the molding paper of each layer are difficult to ensure, the ventilation rate of the paper tubes is influenced, and further, the difference of the ventilation rate among the paper tubes is large, and the ventilation rate is unstable.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: aims to provide a porous paper tube for heating cigarette filter tips, which is used for solving the problems that the prior paper tube structure defects cause punching before the wrapping paper is rolled, the pre-punching ventilation holes on the wrapping paper are difficult to be overlapped, the ventilation rate of the paper tube is influenced, and then the ventilation rate difference between the paper tubes is large, and the ventilation rate is unstable.
In order to realize the technical purpose, the utility model discloses a technical scheme as follows:
the porous paper tube for heating the cigarette filter rod comprises a formed paper body, wherein the formed paper body is parallelogram after being unfolded, the formed paper body is spirally wound to be cylindrical, and a plurality of ventilation holes are formed in the middle of the formed paper body.
Further limiting, the molding paper body is divided into a punching area and an overlapping area on two sides of the punching area, the vent hole is located in the punching area, and the overlapping area is overlapped together when spirally wound into a cylindrical shape. Such structural design divide into two regions to the shaping paper body, and the coincidence does not set up the ventilation hole, and when shaping paper body spiral winding was the tube-shape, only scribbled at the overlap area and establish glue, can avoid glue to leak from the ventilation hole, has also avoided the problem that glue blockked up the ventilation hole simultaneously.
Further inject, the ventilation hole is the round hole, and evenly distributed in the district that punches of shaping paper body. Such structural design is more convenient when punching on the shaping paper body.
Adopt above-mentioned technical scheme's utility model, have following advantage:
1. the paper tube is formed by spirally rolling the single-layer formed paper with a plurality of ventilation holes in the middle, so that the problem that the ventilation rate of the paper tube is influenced because the mutual coincidence of the ventilation holes on the double-layer or multi-layer formed paper is difficult to ensure does not exist, the ventilation rate difference among the paper tubes is small, and the ventilation rate is stable;
2. the molding paper body is divided into two areas, the overlapped part is not provided with the vent hole, when the molding paper body is spirally wound to be cylindrical, glue is only coated in the overlapped area, so that the leakage of the glue from the vent hole can be avoided, and the problem that the vent hole is blocked by the glue is also avoided;
3. the ventilation holes are approximately uniformly distributed on the cylindrical paper tube, so that the ventilation is uniform.
Drawings
The present invention can be further illustrated by the non-limiting examples given in the accompanying drawings;
FIG. 1 is a schematic structural view of an embodiment of a porous paper tube for heating a cigarette filter rod according to the present invention after a body of a plug wrap is unfolded;
FIG. 2 is a schematic structural view of the formed paper body in the embodiment of the porous paper tube for heating the cigarette holder rod of the present invention after forming;
the main element symbols are as follows:
the body of the plug wrap paper 1, the overlapping area 11 and the vent hole 2.
Detailed Description
The present invention will be described in detail with reference to the drawings and specific embodiments, wherein like reference numerals are used for similar or identical parts in the drawings or the description, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In addition, directional terms, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", and the like, used in the embodiments are only directions referring to the drawings, and are not intended to limit the scope of the present invention.
As shown in figure 1 and figure 2, the utility model discloses a porous paper tube for heating cigarette holder stick, including the shaping paper body 1, be parallelogram after the shaping paper body 1 expandes, shaping paper body 1 spiral winding is the tube-shape, and a plurality of ventilation holes 2 have been seted up at shaping paper body 1 middle part.
The molding paper body 1 is divided into a punching area and overlapping areas 11 at two sides of the punching area, the vent holes 2 are positioned in the punching area, and the overlapping areas 11 are overlapped together when spirally wound into a cylinder shape. Divide into two regions to the shaping paper body 1, the coincidence does not set up ventilation hole 2, when 1 spiral winding of shaping paper body is the tube-shape, only scribbles at overlap area 11 and establishes glue, can avoid glue to leak from ventilation hole 2, has also avoided glue to block up the problem in ventilation hole 2 simultaneously.
The ventilation holes 2 are round holes and are uniformly distributed in the punching area of the molding paper body 1. When punching on the body of the molding paper 1, it is more convenient. In fact, ventilation hole 2 also can be located the optional position in the punchhole district to form other arbitrary patterns, this moment, for guaranteeing the homogeneity of the whole ventilation rate of paper tube, only need according to the difference in ventilation hole 2 position, the aperture size and the quantity of adjustment ventilation hole 2 can.
In this embodiment, during manufacturing, glue is coated on one of the overlapping regions 11 of the molding paper body 1 with the ventilation holes 2, and then the molding paper body 1 is rolled up to be spirally wound into a cylindrical shape.
The porous paper tube for heating the cigarette holder rod provided by the utility model is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
