Description

Technical Field

[0001] The invention relates to the field of a feeding strip forming machine for a rolling and splicing machine group, and in particular to a chopping knife disk used for solving the problem of empty and hollow cigarette ends in a process in which a chopping knife disk trims a tobacco bundle. Background Art

[0002] The cigarette roto-rolling unit often has the quality problem of empty ends in the production process. There are many reasons for this problem. One of the main reasons is that the brush wheel does not break the tobacco when brushing it down, but takes it out of the tobacco bundle, resulting in the phenomenon of empty ends and hollow ends in the cigarettes.

[0003] At present, the general solution to this problem is to adjust the installation equipment to the specifications and adjust the gap between the two chopper discs and the brush wheel according to the specifications. However, with the changes in the structure and characteristics of tobacco, it has been found through workshop practice that the problem of the brush wheel taking tobacco out of the tobacco bundle when brushing it off cannot be completely solved, resulting in the phenomenon of empty and hollow cigarettes.

[0004] The present invention aims to provide a chopping blade disc of a newly designed design, in the hope of fundamentally solving the problem that the brush wheel will bring the tobacco out of the tobacco bundle when brushing it, thereby improving the quality of cigarettes. Summary of the invention

[0005] In order to overcome the above problems, the present application provides a chopping knife disc for solving the problem of empty and hollow ends of cigarettes.

[0006] The technical solution adopted by the present invention to solve the technical problem is:

[0007] The chopping disc used to solve the problem of empty and hollow cigarette ends includes:

[0008] A front cleaver disc and a rear cleaver disc rotating in opposite directions;

[0009] The front chopping knife disc and the rear chopping knife disc are in the shape of a disc, and the outer edges of the discs are respectively provided with a lower wire clamping strip and an upper wire clamping strip protruding from the outer edges of the discs;

[0010] The front chopping knife disc is provided with a plurality of wire clamping platforms I at equal angles in the circumferential direction of the outer edge of the disc, and the wire clamping platforms I are formed by vertically sinking the end surface at the outer edge of the front chopping knife disc, so that the outer edge of the wire clamping platform I has a lower wire clamping strip;

[0011] The rear chopping knife disc is provided with wire clamping platforms II at equal angles in the circumferential direction of the outer edge of the disc, and the number of the wire clamping platforms I is the same. The wire clamping platforms II are formed by vertically sinking the end surface at the outer edge of the rear chopping knife disc, so that the outer edge of the wire clamping platform II has an upper wire clamping strip;

[0012] When the front chopping knife disc and the rear chopping knife disc rotate toward each other to the intersection, gaps are left between the lower wire clamping strip and the rear chopping knife disc, the outer edge of the wire clamping platform II, the upper wire clamping strip and the front chopping knife disc, the outer edge of the wire clamping platform I, and the lower wire clamping strip and the upper wire clamping strip;

[0013] The lower wire clamping strip cooperates with the upper wire clamping strip to form an S-shaped wire clamping structure, and forms an upper wire clamping part and a lower wire clamping part which are periodically and alternately arranged up and down as the chopping cutter disc rotates.

[0014] When the front chopping knife disk and the rear chopping knife disk rotate towards each other, the linear speed of the outer edge of each chopping knife disk is the same speed as the tobacco bundle, and the upper wire clamping part located at the outer edge of the chopping knife disk and the lower wire clamping part located at the outer edge of the wire clamping platform periodically and alternately clamp the tobacco bundle up and down, wherein the tobacco bundle density clamped by the lower wire clamping part is greater than the tobacco clamped by the upper wire clamping part.

[0015] As an improvement of the above technical solution, the lower wire clamping strip located at the outer edge of the front chopping cutter disc and the outer edge of the wire clamping platform I forms a complete circle in a top view projection;

[0016] The upper wire clamping strip located at the outer edge of the rear chopping cutter disc and the outer edge of the wire clamping platform II forms a complete circle in a top view projection.

[0017] As an improvement of the above technical solution, the front chopping knife disc is provided with 6 wire clamping platforms I at equal angles on the circumference of the outer edge of the disc, and the rear chopping knife disc is provided with 6 wire clamping platforms II at equal angles on the circumference of the outer edge of the disc.

[0018] As an improvement of the above technical solution, the disc end faces of the front and rear cleaving discs are of equal height, and the end faces of the wire clamping platform I and the wire clamping platform II are of equal height;

[0019] The lower wire clamping strip is lower than the end surface of the front chopping knife disk and the wire clamping platform I, and the upper wire clamping strip is at the same height as the end surface of the rear chopping knife disk and the wire clamping platform II.

[0020] As an improvement of the above technical solution, the longitudinal distance between the lower wire clamping strip and the upper wire clamping strip is 0.1 mm.

[0021] As an improvement of the above technical solution, the front cleaving knife disc and the rear cleaving knife disc are both installed on the cleaving knife shaft.

[0022] As an improvement of the above technical solution, the front chopping knife disc and the rear chopping knife disc are both made of 304 stainless steel.

[0023] The beneficial effects brought by the present invention are:

[0024] The present invention transforms the structure of the chopping knife disk so that the wire clamping strips on the outer edge of the chopping knife disk and the wire clamping strips on the sunken wire clamping platform cooperate with each other, and the tobacco in the process of trimming the tobacco bundle is clamped by the S-shaped wire clamping structure, thereby fundamentally solving the problem of the brush wheel bringing the tobacco out of the tobacco bundle when brushing it down, avoiding the phenomenon of empty and hollow cigarettes, and improving the quality of cigarettes.

[0025] At the same time, the upper and lower wire clamping parts clamp the tobacco bundle periodically and alternately up and down during the process of clamping the tobacco. Since the lower wire clamping part is closer to the lower wire brush wheel than the upper wire clamping part, the tobacco bundle density clamped by the lower wire clamping part is greater than the tobacco clamped by the upper wire clamping part. Therefore, the alternating wire clamping structure can be used to adjust the density of the trimmed tobacco bundle, so that the tobacco density at the end of the formed cigarette is greater than that on the inside, thereby avoiding the production of cigarette strands and further improving the quality of the cigarette.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figures 1 to 3 This embodiment is a chopping knife disc for solving the problem of empty and hollow cigarette ends, comprising a front chopping knife disc 1 and a rear chopping knife disc 2 rotating in opposite directions;

[0034] The front chopping blade disc 1 and the rear chopping blade disc 2 are both disc-shaped, and the outer edges of the wire clamping parts thereof are improved. Specifically:

[0035] The outer edges of the front chopping blade disc 1 and the rear chopping blade disc 2 are respectively provided with a lower wire clamping strip 6 and an upper wire clamping strip 7 protruding from the outer edges of the discs;

[0036] The front chopping blade disc 1 is provided with 6 wire clamping platforms 14 at equal angles in the circumferential direction of the outer edge of the disc, that is, the central angle between adjacent wire clamping platforms 14 is 60°. The wire clamping platform 14 is not an independent structure, but an integrated structure with the front chopping blade disc 1, and is formed by the end surface at the outer edge of the front chopping blade disc 1 vertically sinking and extending, so that the outer edge of the wire clamping platform 14 also has a lower wire clamping strip 6. The outer edge of the wire clamping platform 14 has an arc, which is consistent with the arc of the outer edge of the front chopping blade disc 1 at this position. The lower wire clamping strip 6 located at the outer edge of the disc of the front chopping blade disc 1 and the outer edge of the wire clamping platform 14, its top view projection forms a complete circle.

[0037] Correspondingly, the rear chopping knife disk 2 is provided with 6 wire clamping platforms II5 at equal angles in the circumferential direction of the outer edge of the disk. The wire clamping platform II5 is formed by vertically sinking and extending from the end surface at the outer edge of the rear chopping knife disk 2, and is an integrated structure with the rear chopping knife disk 2, so that the outer edge of the wire clamping platform II5 also has an upper wire clamping strip 7. The outer edge of the wire clamping platform II5 has an arc, which is consistent with the arc of the outer edge of the rear chopping knife disk 2 at this position. The upper wire clamping strip 7 located at the outer edge of the rear chopping knife disk 2 and the outer edge of the wire clamping platform II5, its top view projection forms a complete circle.

[0038] When the front chopping knife disk 1 and the rear chopping knife disk 2 rotate toward each other to the intersection, gaps are left between the lower wire clamping strip 6 and the rear chopping knife disk 2, the outer edge of the wire clamping platform II5, the upper wire clamping strip 7 and the front chopping knife disk 1, the outer edge of the wire clamping platform I4, and the lower wire clamping strip 6 and the upper wire clamping strip 7, so that the lower wire clamping strip 6 and the upper wire clamping strip 7 cooperate to form an S-shaped wire clamping structure, which can better clamp the tobacco bundle based on the friction force provided by it, and form periodic, upper and lower wire clamping parts that alternate up and down as the chopping knife disk rotates.

[0039] When the front chopping blade disc 1 and the rear chopping blade disc 2 rotate towards each other, the linear speed of the outer edge of each chopping blade disc is the same as the speed of the tobacco bundle, and the upper wire clamping part located at the outer edge of the chopping blade disc and the lower wire clamping part located at the outer edge of the wire clamping platform periodically clamp the tobacco bundle. Since the lower wire clamping part is closer to the brush wheel below than the upper wire clamping part, the density of the tobacco bundle clamped by the lower wire clamping part is greater than that of the tobacco clamped by the upper wire clamping part. Therefore, the alternating wire clamping structure can be used to adjust the density of the trimmed tobacco bundle to make it alternately loose and tight, so that the density of tobacco at the end of the formed cigarette is greater than that at the inner side, thereby avoiding the occurrence of tobacco strands at the end of the cigarette.

[0040] Figure 3The figure shows a wire clamping structure of the present embodiment in which the wire clamping strips are staggered up and down and tightly matched: when the front chopping knife disc 1 and the rear chopping knife disc 2 rotate towards each other to the middle intersection, the lower wire clamping strip 6 and the upper wire clamping strip 7 are staggered up and down and left and right in the overlapping part, and the longitudinal distance between the lower wire clamping strip 6 and the upper wire clamping strip 7 is 0.1mm, so that the tobacco in the process of trimming the tobacco bundle can be clamped by the S-shaped wire clamping structure.

[0041] In a preferred embodiment, the disc end faces of the front chopping knife disc 1 and the rear chopping knife disc 2 are at the same height, and the end faces of the wire clamping platform I4 and the wire clamping platform II5 are at the same height; the lower wire clamping strip 6 is lower than the end faces of the front chopping knife disc 1 and the wire clamping platform I4, and the upper wire clamping strip 7 is at the same height as the end faces of the rear chopping knife disc 2 and the wire clamping platform II5. The front chopping knife disc 1 and the rear chopping knife disc 2 are both mounted on the chopping knife shaft 3 and rotate with it.

[0042] In a preferred embodiment, the front blade disc 1 and the rear blade disc 2 are both made of 304 stainless steel.

[0043] In another embodiment, the wire clamping strips of the front and rear chopping blade discs 1 and 2 are arranged in opposite ways, that is, the front chopping blade disc 1 is arranged as an upper wire clamping strip 7 and the rear chopping blade disc 2 is arranged as a lower wire clamping strip 6. The wire clamping principle is the same as that of the present embodiment and will not affect the normal use of the device.

[0044] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
