Description

Technical Field

[0001] The present disclosure relates to the field of cigarette production, and in particular to an end cover assembly of a tobacco trimming device, a tobacco trimming device and a tobacco rolling and splicing device. Background Art

[0002] In the process of cigarette manufacturing, trimmers are mostly used to trim tobacco bundles to obtain cigarettes with qualified weight and compactness. Since the trimmer is in direct contact with a large amount of tobacco, strict sealing requirements are imposed on the trimmer. Once oil leaks, maintenance measures must be taken immediately.

[0003] The end cap of the trimmer is used with an O-ring for oil sealing. When the equipment is running for a long time, the O-ring will age and damage, causing oil leakage and contaminating the tobacco. However, since the outer surface of the end cap is flat and there is no leverage point, the end cap cannot be directly removed to replace the O-ring. The conventional measure is to directly replace the trimmer assembly and calibrate various parameters, which takes a long time and seriously affects the maintenance efficiency. In addition, when repairing the replaced oil-leaking trimmer assembly, many parts need to be disassembled, which takes a long time and requires a large amount of work. Frequent disassembly and assembly can easily damage the parts, affecting the matching accuracy between the parts, thereby reducing the performance of the trimmer assembly. Utility Model Content

[0034] First, the present disclosure provides an end cap assembly of a tobacco trimming device, such as Figures 1 to 6 As shown, including:

[0035] Cylinder 1, extending in the axial direction;

[0036] The end cover 2 is arranged inside the end of the cylinder 1 and covers the opening of the cylinder 1. The end cover 2 includes a cover portion 21, a ring portion 22 and a protrusion 23. The plane where the cover portion 21 is located is perpendicular to the axial direction. The ring portion 22 is connected to the cover portion 21 and is located inside the axial direction of the cover portion 21. The protrusion 23 is connected to the cover portion 21 and is located outside the axial direction of the cover portion 21. The protrusion 23 is configured to receive an external force to plug and unplug the end cover 2 in the axial direction; and

[0037] The sealing ring 3 is connected between the outer wall of the annular body 22 and the inner wall of the cylinder 1 .

[0038] Specifically, the surface curvature of the ring body 22 matches the size of the sealing ring 3. The ring body 22 is connected to the cover body 21 and extends axially inward to provide a platform for the installation of the sealing ring 3. The sealing ring 3 and the ring body 22 fit tightly together to perform a sealing function. The sealing ring 3 can prevent oil from leaking from the inside of the cylinder 1.

[0039] Specifically, the protrusion 23 is connected to the outer surface of the cover body 21. When the end cover 2 needs to be removed, the operator can apply an external force to the protrusion 23 to conveniently remove the end cover 2. Optionally, the protrusion 23 may include a handle, a pull ring or a threaded hole, etc., which is convenient for applying an external force. Optionally, the cylinder 1 may be a housing of a double gear shaft, etc., and the sealing ring 3 may be an O-ring, etc.

[0040] Specifically, when oil leakage occurs at the end cover of the dressing device, the operator can use the protrusion 23 to disassemble and assemble the end cover 2 and replace the sealing ring 3, which can avoid replacing the dressing device assembly, avoid calibrating various parameters, reduce maintenance time, and greatly improve maintenance efficiency; by not having to repair the oil leakage dressing device assembly, it is possible to avoid disassembling many parts, avoid frequent disassembly and assembly that may cause damage to parts, avoid affecting the matching accuracy between parts, and thus avoid reducing the performance of the dressing device assembly.

[0041] The tobacco trimming device end cover assembly of this embodiment has a simple structure and reliable sealing, and can prevent the oil inside the cylinder 1 from leaking and contaminating the tobacco material; the protrusion 23 is connected to the outer surface of the cover body 21 to provide a force application point, which is convenient for the operator to directly realize the quick disassembly and assembly of the end cover 2 without replacing the trimming device assembly, and can solve the problem of large workload and long time consumption in the prior art for repairing the oil leakage fault of the trimming device end cover, and can reduce the time consumption for repairing the oil leakage fault of the trimming device end cover, improve the maintenance efficiency of the tobacco trimming device, and reduce the difficulty of maintenance; it can protect other parts of the tobacco trimming device from frequent disassembly and assembly to reduce the matching accuracy, thereby improving the operating efficiency of the tobacco trimming device.

[0042] In some embodiments, Figures 1 to 3 As shown, a threaded hole 231 is provided on the protruding portion 23 , and the threaded hole 231 is configured to be threadedly matched with the force applying member.

[0043] Specifically, a threaded hole 231 with internal threads is provided on the protruding portion 23. When the end cover 2 needs to be removed, a force-applying member can be screwed into the threaded hole 231 to conveniently remove the end cover 2 from the cylinder body 1. Optionally, the force-applying member can be a screw or a bolt.

[0044] This embodiment cooperates with the force-applying member through the threaded hole 231 on the protrusion 23, and can accurately adjust the position of the end cover 2 relative to the barrel 1 as needed, so that the operator can quickly disassemble and assemble the end cover 2, improve the maintenance efficiency of the tobacco trimming device, and protect the various components of the tobacco trimming device from frequent disassembly and assembly to reduce the matching accuracy.

[0045] In some embodiments, Figure 1 and Figure 2 As shown, one end of the ring body 22 away from the cover body 21 is provided with a chamfer 221 .

[0046] Specifically, for the end cover 2 that needs to be disassembled, the chamfer 221 can avoid rigid extrusion when the cover body 21 is connected to the cylinder body 1, thereby improving the disassembly efficiency of the end cover 2.

[0047] This embodiment provides chamfers on the cover body 21 , which can facilitate installation and alignment of the end cover 2 , improve the efficiency of assembly and disassembly of the end cover 2 , and improve the sealing performance of the sealing ring 3 .

[0048] In some embodiments, Figure 1 As shown, a first groove portion 11 is provided on the inner side wall of the cylinder 1 . The first groove portion 11 is annular and is configured to accommodate the sealing ring 3 . The size of the first groove portion 11 is adapted to the size of the sealing ring 3 .

[0049] Specifically, the first groove portion 11 can accommodate and limit the sealing ring 3, and the first groove portion 11 and the sealing ring 3 are closely matched to achieve a sealing effect. Specifically, through the accommodation and limiting effect of the first groove portion 11, it is possible to ensure that the position of the sealing ring 3 is accurate during installation, and to avoid sealing failure caused by the misalignment of the sealing ring 3; the first groove portion 11 makes it easier to align and embed the sealing ring 3 during the assembly process, which can reduce the assembly time of the sealing ring 3 and reduce the difficulty of assembling the end cover 2.

[0050] Specifically, the first groove portion 11 can provide physical protection for a portion of the sealing ring 3 in the radial direction to prevent damage due to external squeezing or friction during installation or use, thereby extending the service life of the sealing ring 3.

[0051] This embodiment provides a first groove portion 11 on the cylinder body 1 to accommodate the sealing ring 3 , thereby ensuring that the sealing ring 3 is accurately positioned during installation, reducing the assembly time of the sealing ring 3 , and extending the service life of the sealing ring 3 .

[0052] In some embodiments, Figure 1 As shown, a second groove portion 12 is provided on the inner side wall of the barrel 1, the second groove portion 12 is annular and is provided on the axial outer side of the cover body 21, and the end cover assembly of the tobacco trimming device also includes:

[0053] The limiting retaining ring 4 is installed in the second groove portion 12 . The limiting retaining ring 4 abuts against the cover body portion 21 and is configured to axially limit the end cover 2 .

[0054] Specifically, the limit ring 4 installed in the second groove portion 12 can limit the axial movement range of the end cover 2, ensure that the end cover 2 is fixed in the required position, prevent the end cover 2 from shifting due to vibration or other external forces, and improve the sealing performance of the end cover assembly.

[0055] Specifically, when oil leakage occurs at the end cover assembly of the tobacco trimming device, the limit retaining ring 4 can be removed, and a force-applying member can be screwed into the threaded hole 231 to pull out the end cover, and the sealing ring 3 can be directly replaced.

[0056] The limit ring 4 of this embodiment can limit the axial movement range of the end cover 2, so that the position of the end cover 2 in the cylinder 1 is fixed, and the sealing performance of the end cover assembly is improved.

[0057] Secondly, if Figure 4 and Figure 5 As shown, the present disclosure also provides a tobacco trimming device, including the tobacco trimming device end cover assembly of the above embodiment. Specifically, the tobacco trimming device trims and cuts the tobacco material, and optionally, the tobacco material can be a tobacco bundle or the like.

[0058] The tobacco trimming device of this embodiment has a reliable sealing of the end cover assembly, and the protrusion 23 connected to the outer surface of the cover body 21 can provide a force application point, which is convenient for the operator to directly and quickly disassemble and assemble the end cover 2 when an oil leakage failure occurs, without replacing the trimming device assembly. The tobacco trimming device has a high maintenance efficiency because other components are exempted from frequent disassembly and assembly, and the matching accuracy of each component is high, and the tobacco trimming device has a high operating efficiency.

[0059] In some embodiments, Figure 4 and Figure 6 As shown, a double gear shaft 10 extending in the axial direction is installed in the cylinder 1. Specifically, the double gear shaft 10 is connected between the driving component and the working component, and is configured to transmit the rotational motion of the driving component to the two working components.

[0060] The tobacco trimming device of this embodiment realizes power transmission through the double gear shaft 10, and can efficiently trim and cut the tobacco material.

[0061] In some embodiments, Figures 4 to 6 As shown, the double gear shaft 10 includes a first gear segment 101 and a second gear segment 102, and the transmission directions of the first gear segment 101 and the second gear segment 102 are opposite. The tobacco trimming device also includes:

[0062] The first flattening plate 5 is transmission-connected to the first gear segment 101; and

[0063] The second smoothing plate 6 is transmission-connected to the second gear section 102. The second smoothing plate 6 and the first smoothing plate 5 are located in the same plane, and the second smoothing plate 6 and the first smoothing plate 5 rotate in opposite directions. The second smoothing plate 6 is configured to cooperate with the first smoothing plate 5 to achieve trimming of the tobacco material.

[0064] Specifically, the first flattening disc 5 and the second flattening disc 6 cooperate to trim and remove excess tobacco in the tobacco stream, so that the amount of tobacco fed to the next process meets the standard cigarette weight. Optionally, the first flattening disc 5 rotates counterclockwise, and the second flattening disc 6 rotates clockwise.

[0065] The tobacco trimming device of this embodiment drives the first flattening disc 5 and the second flattening disc 6 to rotate in opposite directions through the two gear sections of the double gear shaft 10, so as to efficiently trim and cut the tobacco material.

[0066] In some embodiments, Figure 5 As shown, the tobacco trimming device further comprises a brush wheel 7, which is configured to brush the trimmed tobacco material.

[0067] In some embodiments, at the trimming position, the linear speed directions of the first flattening disk 5 and the second flattening disk 6 are the same as the advancing direction of the tobacco material.

[0068] Specifically, in order to prevent the two flattening disks from generating lateral force on the tobacco when trimming the tobacco, the two flattening disks are symmetrically distributed relative to the tobacco flow. Therefore, at the shearing position, the linear speed direction of the two flattening disks is the same as the direction of the tobacco flow, and the tobacco flow will not be disturbed.

[0069] In this embodiment, the linear speed direction of the two leveling disks is the same as the advancing direction of the tobacco material, so that the two leveling disks can avoid applying lateral force to the tobacco material and avoid disturbance of the conveying of the tobacco material by the two leveling disks.

[0070] Secondly, the present disclosure also provides a tobacco rolling and joining device, including the tobacco trimming device end cover assembly of the above embodiment, or the tobacco trimming device of the above embodiment.

[0071] Alternatively, the tobacco rolling equipment may include a PROTOS 70 model cigarette making machine.
