Description

Technical Field

[0001] The utility model relates to a defective cigarette recovery device, in particular to a spiral cutting mechanism for the surface of defective cigarettes. Background Art

[0002] When cigarette factories produce cigarettes, due to defects in raw materials, failures in cigarette making equipment, failures in auxiliary material supply equipment, etc., a certain amount of defective cigarettes with defects in appearance, insufficient tobacco fullness and tightness, unqualified connection, and inconsistent draw resistance will be produced. In order to improve the utilization rate of raw materials, it is necessary to extract the tobacco from these defective cigarettes without loss and put them into the same level cigarette production line for recycling.

[0003] Currently, various tobacco extraction methods are available on the market, primarily using cutting or beating methods to break up the cigarettes. Cutting uses a linear cut to slit the cigarette paper along its axis. If the knife cuts through the adhesive of the cigarette, small strips of paper will be produced, which cannot be removed and subsequently affect the purity of the tobacco. Furthermore, after the linear cut, the curled paper cannot be fully opened, making subsequent extraction and recovery difficult. Beating uses the impact of cigarettes to separate the tobacco, but the tobacco is stretched within the paper wrapper and cannot be completely released. Therefore, neither method achieves optimal results. Summary of the Invention

[0004] The utility model provides a spiral cutting mechanism for the outer skin of defective cigarettes, which solves the problem of spirally cutting the outer skin of cigarettes and completely recovering the tobacco. The technical solution is as follows:

[0005] A spiral cutting mechanism for the surface of defective cigarettes, comprising a cigarette rotation device and a cutting device mounted on a fixed base plate, wherein the cigarette rotation device is provided with two cigarette rotation shafts that rotate synchronously, and a cutting device is arranged obliquely above the cigarette rotation device, and the cutting device is provided with a cigarette propulsion shaft and a cigarette propulsion and cutting shaft arranged in front and behind, and the cigarette propulsion and cutting shaft is provided with a cigarette cutting knife with an annular structure, and the center of the cigarette cutting knife is located between the two cigarette rotation shafts.

[0006] The cigarette rotation device includes a cigarette rotation drive motor, a cigarette rotation synchronous transmission belt and a cigarette rotation shaft fixing plate. The two cigarette rotation shafts are placed in parallel, and both ends are rotatably fixed on the cigarette rotation shaft fixing plate. The cigarette rotation shaft fixing plate is installed on a fixed base plate; one of the cigarette rotation shafts is driven by the cigarette rotation drive motor, and the other cigarette rotation shaft is driven to rotate by the cigarette rotation synchronous transmission belt.

[0007] The two cigarette rotation axes are respectively a first rotation axis and a second rotation axis having the same shape and size.

[0008] Both ends of the cigarette rotation shaft are connected to the cigarette rotation shaft fixing plate through the first bearing. The cigarette rotation shaft is fixedly connected to the inner ring of the first bearing, and the outer ring of the first bearing is fixedly connected to the cigarette rotation shaft fixing plate.

[0009] The cutting device also includes a cigarette pushing drive motor, a cigarette pushing fixed plate and a cigarette pushing synchronous transmission belt. The cigarette pushing shaft is placed parallel to the cigarette pushing cutting shaft, and both ends can rotate freely on the cigarette pushing fixed plate. The cigarette pushing fixed plate is installed on the fixed bottom plate; the cigarette pushing shaft is driven by the cigarette pushing drive motor, and the cigarette pushing cutting shaft is driven to rotate synchronously by the cigarette pushing synchronous transmission belt.

[0010] The cigarette propulsion axis and the cigarette propulsion cutting axis have the same contact surface with the cigarette, and the distance between them is no greater than the length of the cigarette.

[0011] The cigarette propulsion axis and the cigarette propulsion cutting axis of the cutting device are located obliquely above the two cigarette rotation axes of the cigarette rotation device.

[0012] The distance between the cigarette propulsion axis and the cigarette propulsion cutting axis of the cutting device and the two cigarette rotation axes of the cigarette rotation device is less than the diameter height of the cigarette, so that the cigarette cutting knife can cut the outer skin of the cigarette.

Therefore, it is highly practical and has great applicability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] like Figure 1 As shown, the spiral cutting mechanism for the surface of defective cigarettes includes a cigarette rotation device 2 and a cutting device 3 installed on a fixed base plate 1. The cigarette rotation device 2 is provided with two cigarette rotation shafts 205 that rotate synchronously. The cutting device 3 is arranged obliquely above the cigarette rotation device 2. The cutting device 3 is provided with a cigarette propulsion shaft 305 and a cigarette propulsion and cutting shaft 306 arranged in front and behind. The cigarette propulsion and cutting shaft 306 is provided with a cigarette cutting knife 307 with an annular structure. The center of the cigarette cutting knife 307 is located between the two cigarette rotation shafts 205.

[0020] The four corners of the fixed base plate 1 are provided with screw holes, which can be fixed to the ground or other platforms by bolts.

[0021] The cigarette rotation device 2 comprises a cigarette rotation drive motor 201, a cigarette rotation motor fixing plate 202, a cigarette rotation synchronous transmission belt 203, a cigarette rotation shaft fixing plate 204, and a cigarette rotation shaft 205. The cigarette rotation drive motor 201 is fixed to the cigarette rotation motor fixing plate 202 to act as a drive. Two cigarette rotation shafts 205 are horizontally positioned and fixed to the cigarette rotation shaft fixing plate 204 and can rotate. The cigarette rotation drive motor 201 is connected to one of the cigarette rotation shafts 205 to provide it with power. The two cigarette rotation shafts 205 are connected to the cigarette rotation synchronous transmission belt 203 to enable them to rotate synchronously.

[0022] The two cigarette rotation axes 205, a first rotation axis and a second rotation axis of identical shape and size, prevent cigarettes from falling. The ends of the cigarette rotation axis 205 are fixed to the fixed base plate 1 via cigarette rotation axis fixing plates 204. Furthermore, first bearings are mounted on both ends of the cigarette rotation axis 205 and fixedly connected to the inner ring of the first bearing. The outer ring of the first bearing is fixedly connected to the cigarette rotation axis fixing plates 204.

[0023] The first rotating shaft is driven by a cigarette self-rotation drive motor 201, which is fixed to the fixed base plate 1 via a cigarette self-rotation motor fixing plate 202. The first rotating shaft drives the second rotating shaft via a cigarette self-rotation synchronous transmission belt 203, so that the first and second rotating shafts rotate in the same direction. The cigarette self-rotation synchronous transmission belt 203 is located on one side of the cigarette self-rotation drive motor 201. When a cigarette is placed between the two cigarette self-rotation shafts 205, the cigarette rotates with the axis as the two cigarette self-rotation shafts 205 rotate.

[0024] The cutting device 3 also includes a cigarette propulsion drive motor 301, a cigarette propulsion motor fixing plate 302, a cigarette propulsion fixing plate 303, and a cigarette propulsion synchronous transmission belt 304. The cigarette propulsion drive motor 301 is fixed to the cigarette propulsion motor fixing plate 302 and acts as a drive. The cigarette propulsion drive motor 301 is connected to the cigarette propulsion cutting shaft 306, providing it with power to drive the cigarette cutting blade 307 to rotate. The cigarette propulsion shaft 305 is connected to the cigarette propulsion cutting shaft 306 via the cigarette propulsion synchronous transmission belt 304, enabling synchronous rotation.

[0025] The cigarette propulsion shaft 305 and the cigarette propulsion cutting shaft 306 are positioned parallel to each other, their ends freely rotating on the cigarette propulsion fixing plate 303. The distance between them is no greater than the length of the cigarette. Furthermore, the cigarette propulsion shaft 305 and the cigarette propulsion cutting shaft 306 have the same contact surface height with the cigarette. A second bearing is mounted on each end of the cigarette propulsion shaft 305 and fixedly connected to the inner ring of the second bearing. The outer ring of the second bearing is fixedly connected to the cigarette propulsion fixing plate 303. A third bearing is mounted on each end of the cigarette propulsion cutting shaft 306 and fixedly connected to the inner ring of the third bearing. The outer ring of the third bearing is fixedly connected to the cigarette propulsion fixing plate 303.

[0026] The cigarette cutting blade 307 is mounted on the cigarette advancing and cutting shaft 306. The cigarette advancing and cutting shaft 305 and the cigarette advancing and cutting shaft 306 are located obliquely above the two cigarette rotating shafts 205. Furthermore, the distance between the cigarette advancing and cutting shaft 305 and the two cigarette rotating shafts 205 of the cutting device 3 is less than the height of the cigarette diameter, allowing the cigarette cutting blade 307 to cut the outer skin of the cigarette 4.

[0027] When a cigarette 4 is transported onto the two cigarette rotation shafts 205 and enters directly below the cigarette propulsion shaft 305, the cigarette rotation shaft 205 rotates due to friction with the cigarette 4, and the cigarette propulsion shaft 305 pushes the cigarette 4 forward by friction. When the front end of the cigarette 4 moves to the cigarette propulsion cutting shaft 306, the cigarette cutting blade 307 on the cigarette propulsion cutting shaft 306 cuts the outer skin of the cigarette 4, forming a spiral cutting pattern, and the cigarette is cut.

[0028] The cigarette rotation motor fixing plate 202, the two cigarette rotation shaft fixing plates 204, the cigarette propulsion motor fixing plate 302 and the four cigarette propulsion fixing plates 303 are all fixed to the fixed base plate 1 by bolts, and the fixed base plate 1 is provided with multiple sets of adjustment screw holes (not shown), so that the positions of the cigarette propulsion motor fixing plate 302 and the cigarette propulsion fixing plate 303 can be adjusted, thereby realizing the adjustment of the angle of the cutting device 3 relative to the cigarette rotation device 2 to change the spiral shape.

[0029] The utility model has a simple structure and a simple device, and the automated operation saves time and labor. It only cuts the outer surface of the cigarette paper, effectively cuts the cigarette without damaging the tobacco, and can achieve lossless tobacco recovery, so it is highly practical and has great applicability.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
