Method used

The pitch of screw thread on threaded connecting rod is generally 1-5mm, and concrete pitch value will generally determine according to factors such as the tightness between the material of filter tip rod, the type of packaging material, packaging material and filter tip rod . By setting the connecting rod into a threaded shape, the distance of the smoke flow can be extended, the tar content in the cigarette can be reduced, and the health damage of the cigarette to the smoker can be appropriately reduced; at the same time, the taste of the cigarette is softer and the aroma is mellow.
[0021] Fig. 1 and Fig. 2 are cigarette filter tips of the present invention. The cigarette filter includes a filter rod 1 and a packaging material coated on the outer surface of the filter rod 1, and the packaging material can be a coil paper or tipping paper, or a sleeve. The filter rod 1 includes short rods 2 arranged at intervals along the axial direction. The short rods 2 are cylindrical and have a smooth outer surface. The length of the short rods 2 is 5-10mm. The adjacent short rods 2 are connected to each other by connecting rods 3, and the length of the connecting rods 3 is 5-50mm. A continuous threaded groove 4 is provided along the annular outer surface of the connecting rod 3 , that is, adjacent short rods 2 are connected by a threaded connecting rod. The filter rod 1 is formed by alternately connecting short rods 2 and threaded connecting rods at intervals. By arranging the short rods 2, it is possible to pr...

Abstract

The invention relates to a filter tip, in particular to a cigarette filter tip. The cigarette filter tip comprises a filter tip stick. The filter tip stick comprises cylindrical short sticks axially arranged at intervals. The outer surfaces of the short sticks are smooth. Every two adjacent short sticks are connected through a connecting stick. A continuous groove is formed on the annular outer surface of each connecting stick. The filter tip stick is formed by alternately connecting the short sticks and the connecting sticks with the continuous grooves at intervals. An air guide groove is axially formed in each short stick. The air guide grooves in every two adjacent short sticks form an included angle of 180 degrees. The depths of the air guide grooves are not less than those of the grooves of the connecting sticks. According to the filter tip disclosed by the invention, adjacent filter tip sticks are prevented from being meshed in a molding process, the cigarette filter tip can be conveniently molded, smoke can be smoothly circulated, the flowing distance of the smoke is prolonged, and the damage of cigarettes to the health of a smoker is appropriately reduced.

Example Embodiment

[0020] Example 1
[0021] figure 1 with figure 2 It is the cigarette filter of the present invention. The cigarette filter tip includes a filter rod 1 and a packaging material coated on the outer surface of the filter rod 1. The packaging material may be tray paper or tipping paper, or a sleeve. The filter rod 1 includes short rods 2 arranged at intervals along the axial direction. The short rods 2 are cylindrical and have a smooth outer surface. The length of the short rods 2 is 5-10 mm. The adjacent short rods 2 are connected to each other by connecting rods 3, and the length of the connecting rods 3 is 5-50mm. A continuous threaded groove 4 is provided along the annular outer surface of the connecting rod 3, that is, the adjacent short rods 2 are connected by a threaded connecting rod. The filter rod 1 is formed by alternately connecting short rods 2 and threaded connecting rods. By providing short rods 2, it is possible to prevent multiple threaded connecting rods from interlocking during the forming process of the filter rod, so that the filter The sticks fall out of the falling hopper smoothly; in addition, when the filter stick 1 is cut in sections, the short stick 2 is divided at the position to prevent the packaging material from collapsing, and the packaging material will not cover the filter stick The end face of 1 ensures smooth ventilation of the filter tip. The threaded groove 4 in this embodiment is a single-threaded groove, and may also be a double-threaded groove, a three-threaded groove or a multi-threaded groove.
[0022] The thread pitch of the threaded connecting rod is generally 1-5mm. The specific thread pitch value is generally determined according to factors such as the material of the filter rod, the type of packaging material, and the tightness between the packaging material and the filter rod. By setting the connecting rod into a threaded shape, the distance of the smoke flow can be extended, the tar content in the cigarette can be reduced, and the health damage of the cigarette to the smoker can be appropriately reduced; at the same time, the cigarette has a softer taste and a mellow aroma.
[0023] Each short rod 2 is provided with an air guide groove 5 along the axial direction, and the air guide grooves 5 on adjacent short rods 2 form an included angle of 180° with each other. Since the filter rod is divided into two short rods, the end face of the filter rod after division is provided with air guide grooves. The air guide grooves can make the flow of smoke more smooth. At the same time, the air guide groove 5 is provided to facilitate the filter rod Manufacturing molding; In addition, by making the adjacent air guide grooves 5 have an angle of 180° with each other, the contact area between the filter rod and the negative pressure belt is increased, and the adsorption force between the filter rod and the negative pressure belt is improved , It is more convenient to shape the filter rod. The depth of the air guide groove 5 is not less than the depth of the threaded groove 4 on the connecting rod.
[0024] After the filter rod 1 in the present invention is processed and formed, packaging materials such as paper, tipping paper, etc. are wrapped on the outer surface of the filter rod 1, and then the filter rod 2 is placed on the short rod 2 according to the length of the required filter. 1 Carry out the division, and the filter tip obtained after division and the processed cigarette are connected by bonding or other means to complete the manufacture of cigarettes.

Example Embodiment

[0025] Example 2
[0026] image 3 It is the cigarette filter described in Example 2. The difference from Embodiment 1 is that the groove on the outer surface of the connecting rod 3 is a "Z"-shaped continuous groove 6 arranged along the axial direction of the connecting rod 3, that is, formed by connecting Z-shaped grooves in the axial direction. At least one “Z”-shaped continuous groove 6 is arranged along the axial direction of the connecting rod 3. When there are more than one, each “Z”-shaped continuous groove 6 is arranged at intervals along the radial direction of the connecting rod 3.
[0027] Others are the same as in Example 1.

Example Embodiment

[0028] Example 3
[0029] Figure 4 It is the cigarette filter described in Example 3. The difference from Embodiment 1 is that the groove on the outer surface of the connecting rod 3 is an "S"-shaped continuous groove 7 arranged along the axial direction of the connecting rod 3, that is, it is formed by connecting S-shaped grooves in the axial direction. At least one “S”-shaped continuous groove 7 is provided along the axial direction of the connecting rod 3. When there are more than one, each “S”-shaped continuous groove 7 is arranged at intervals along the radial direction of the connecting rod 3.
