Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a conveying device for wiping tobacco leaves. Background Technology

[0002] In the early stages of tobacco leaf threshing and re-drying, the tobacco leaves are usually torn into sheets of a certain size (a sheet of a certain size: the tobacco leaf is torn into two parts) to facilitate subsequent processing such as leaf moistening, drying, and threshing. During the process of tearing the tobacco leaves into sheets of a certain size, the surface of the freshly torn sheets will also be covered with stains because the whole tobacco leaves may have been contaminated during transportation.

[0003] Currently, when wiping stains from tobacco leaves, a conveying device for wiping stains is typically installed downstream of the tobacco leaf tearing station. As the stained tobacco leaves pass through this device, wiping rollers arranged side-by-side on the same conveying plane sequentially wipe the stains from the tobacco leaf surface, thus transferring the stains to the rollers and completing the wiping process. While this method can remove stains from tobacco leaves, because the wiping rollers operate on the same horizontal plane and at the same conveying speed, the degree of surface wiping is not always sufficient.

[0004] Therefore, it is necessary to improve and redesign the conveying device for wiping stains on the surface of tobacco leaves in order to solve the problem that the wiping rollers used to wipe stains on the surface of tobacco leaves in the existing conveying device are all on the same horizontal plane and operate at the same conveying speed, resulting in a low degree of wiping of the tobacco leaf surface when the tobacco leaves are wiped by the wiping rollers. Utility Model Content

[0005] The purpose of this invention is to propose a conveying device for wiping tobacco leaves, in order to solve the problem that in existing conveying devices, the wiping rollers used to wipe the stains on the surface of tobacco leaves are all on the same horizontal plane and operate at the same conveying speed, resulting in insufficient wiping of the tobacco leaf surface when the tobacco leaves are wiped by the wiping rollers.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] The conveying device for wiping tobacco leaves includes

[0008] frame;

[0009] The first wiping roller and the second wiping roller are rotatably connected at both ends to the side wall of the frame, and the first wiping roller and the second wiping roller are arranged alternately and descend sequentially along the frame;

[0010] A first driving member and a second driving member are provided. The first driving member is connected to a plurality of first wiping rollers to drive the plurality of first wiping rollers to rotate, and the second driving member is connected to a plurality of second wiping rollers to drive the plurality of second wiping rollers to rotate.

[0011] Preferably, the first driving component includes a first motor and a first transmission component; the first motor is disposed on one of the outer side walls of the frame, and the first motor is connected to a plurality of first wiping rollers through the first transmission component.

[0012] Preferably, the first transmission component includes a first driving sprocket, a plurality of first driven sprockets, and a first transmission chain; the first driving sprocket is sleeved on the output shaft of the first motor, and the first driving sprocket is connected to the plurality of first driven sprockets through the first transmission chain, and each first driven sprocket is respectively sleeved on the shaft of each first wiping roller.

[0013] Preferably, the second driving component includes a second motor and a second transmission component; the second motor is mounted on another side wall of the frame, and the second motor is connected to a plurality of second wiping rollers via the second transmission component.

[0014] Preferably, the second transmission component includes a second driving sprocket, a plurality of second driven sprockets, and a second transmission chain; the second driving sprocket is sleeved on the output shaft of the second motor, and the second driving sprocket is connected to the plurality of second driven sprockets through the second transmission chain, and each second driven sprocket is respectively sleeved on the rotating shaft of each second wiping roller.

[0015] Preferably, the inner bottom of the frame directly below both the second wiping roller and the first wiping roller is inclined.

[0016] During operation, when wiping the stained tobacco leaves, the first wiping roller on the frame is driven to rotate clockwise at a first speed by the first driving component, and the second wiping roller on the frame is driven to rotate clockwise at a second speed by the second driving component. Then, the stained tobacco leaves are placed on the differential conveying device, and the stained tobacco leaves pass through the surfaces of the first and second wiping rollers in sequence. During this process, because the first and second wiping rollers rotate at different speeds, and because the first and second wiping rollers are arranged alternately and descend sequentially along the frame, the different speeds and alternating descent of the first and second wiping rollers increase the degree of wiping with the surface of the tobacco leaves. This improves the problem in existing conveying devices where the wiping rollers for wiping stains on the surface of tobacco leaves are all on the same horizontal plane and operate at the same conveying speed, resulting in insufficient wiping of the tobacco leaf surface when the tobacco leaves are wiped by the wiping rollers.

[0017] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0018] This invention utilizes a differential conveying device for wiping tobacco leaves, comprising a frame, a first wiping roller, a second wiping roller, a first drive component, and a second drive component. When wiping tobacco leaves with stains, the stained tobacco leaves pass sequentially over the surfaces of the first and second wiping rollers. During this process, the different rotational speeds of the first and second wiping rollers, coupled with their alternating and sequentially descending arrangement along the frame, increase the degree of wiping on the tobacco leaf surface. This addresses the problem in existing conveying devices where the wiping rollers are all on the same horizontal plane and operate at the same conveying speed, resulting in insufficient wiping of the tobacco leaf surface when the wiping rollers remove stains.

Detailed Implementation

[0028] like Figure 1-8As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example

[0030] Existing methods for wiping tobacco leaves can remove stains, but because the wiping rollers used to wipe the stains on the tobacco leaf surface are all on the same horizontal plane and operate at the same conveying speed, the degree of wiping of the tobacco leaf surface is not high when the tobacco leaf is wiped by the wiping rollers.

[0031] Therefore, this application proposes a conveying device for wiping tobacco leaves to solve the problem that in existing conveying devices, the wiping rollers for wiping stains on the surface of tobacco leaves are all on the same horizontal plane and operate at the same conveying speed, resulting in insufficient wiping of the tobacco leaf surface when the tobacco leaves are wiped by the wiping rollers.

[0032] For details, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 The conveying device for wiping tobacco leaves includes a frame 1, a first wiping roller 2, a second wiping roller 3, a first drive unit 5, and a second drive unit 6. The two ends of the first wiping roller 2 and the second wiping roller 3 are rotatably connected to the side wall of the frame 1, and the first wiping roller 2 and the second wiping roller 3 are arranged alternately and descend sequentially along the frame 1. The first drive unit 5 is connected to multiple first wiping rollers 2 to drive multiple first wiping rollers 2 to rotate, and the second drive unit 6 is connected to multiple second wiping rollers 3 to drive multiple second wiping rollers 3 to rotate.

[0033] In practical application, when wiping stained tobacco sheets, the first wiping roller 2 on the frame 1 is driven by the first driving component 5 to rotate clockwise at a first speed, and the second wiping roller 3 on the frame 1 is driven by the second driving component 6 to rotate clockwise at a second speed. Then, the stained tobacco sheets are placed onto the differential conveying device, and the stained tobacco sheets pass sequentially over the surfaces of the first wiping roller 2 and the second wiping roller 3. During this process, due to the different rotational speeds of the first wiping roller 2 and the second wiping roller 3, and the fact that the first wiping roller 2 and the second wiping roller 3 are aligned along the frame... By alternating and descending the first wiping roller 2 and the second wiping roller 3 with different rotation speeds, the degree of wiping with the tobacco leaf surface is increased. This scrapes the stains attached to the tobacco leaf onto the first wiping roller 2 and the second wiping roller 3. Then, the operator cleans the first wiping roller 2 and the second wiping roller 3 while the differential conveyor is stopped. This solves the problem in the existing conveyor system where the wiping rollers for wiping stains on the tobacco leaf surface are all on the same horizontal plane and operate at the same conveying speed, resulting in insufficient wiping of the tobacco leaf surface when the tobacco leaf is wiped by the wiping rollers.

[0034] It should be noted that the first wiping roller 2 and the second wiping roller 3 can be industrial brush rollers. Industrial brush rollers are existing technology and have not been improved or designed, so their structure will not be described in detail. Among them, the bristles in the brush of the industrial brush roller have a certain degree of hardness.

[0035] Please see Figure 3 The first driving member 5 for driving multiple first wiping rollers 2 to rotate clockwise includes a first motor 7 and a first transmission member 8; wherein, the first motor 7 serves as the power source for the rotation of multiple first wiping rollers 2; the first transmission member 8 is used to transmit the power of the rotation of the first motor 7 to the multiple first wiping rollers 2 respectively, so as to drive the multiple first wiping rollers 2 to rotate.

[0036] Specifically, the first motor 7 is fixedly mounted on one of the outer side walls of the frame 1, and the output end of the first motor 7 is connected to the first transmission component 8. The first transmission component 8 is also connected to multiple first wiping rollers 2.

[0037] In practical applications, when the first driving member 5 drives the multiple first wiping rollers 2 to rotate, the first driving member 5 can be driven to rotate, and the rotating first driving member 5 will drive the multiple first wiping rollers 2 to rotate through the first transmission member 8.

[0038] It should be noted that the first motor 7 can be a frequency-modulated motor, which is a motor with adjustable speed. This frequency-modulated motor is existing technology, and no improvements or designs have been made to it, so its structure will not be described in detail.

[0039] Please see Figure 8The first transmission component 8, used to transmit the rotational power of the first motor 7 to the plurality of first wiping rollers 2, includes a first driving sprocket 9, a plurality of first driven sprockets 10, and a first transmission chain 11; wherein, the first driving sprocket 9 is used to transmit the rotational power of the first motor 7 to the first transmission chain 11; the first transmission chain 11 is used to transmit the transmitted power to the plurality of spaced-apart first driven sprockets 10; and the plurality of first driven sprockets 10 are used to transmit the power to the plurality of first wiping rollers 2.

[0040] Specifically, the first drive sprocket 9 is fixedly sleeved on the output shaft of the first motor 7. The first drive sprocket 9 is connected to multiple first driven sprockets 10 through the first transmission chain 11. Each first driven sprocket 10 is fixedly sleeved on the rotating shaft connected to each first wiping roller 2. The rotating shaft connected to each first wiping roller 2 is rotatably connected to the side wall of the frame 1. One end of the rotating shaft connected to the first wiping roller 2 does not extend out of the outer side wall of the frame 1, while the other end of the rotating shaft connected to the first wiping roller 2 extends out of the outer side wall of the frame 1.

[0041] In practical applications, when the first motor 7 drives multiple first wiping rollers 2 to rotate, the first motor 7 can be controlled to rotate by a controller connected to the first motor 7. The rotating first motor 7 drives the first drive sprocket 9 to rotate. Under the rotation of the first drive sprocket 9, the first transmission chain 11 connected to the first drive sprocket 9 drives multiple first driven sprockets 10 to rotate, indirectly driving the multiple first wiping rollers 2 sleeved with the first driven sprockets 10 to rotate.

[0042] Please see Figure 5 The second driving component 6 for driving the second wiping roller 3 to rotate includes a second motor 12 and a second transmission component 13; wherein, the second motor 12 serves as the power source for the rotation of the multiple second wiping rollers 3; the second transmission component 13 is used to transmit the power of the rotation of the second motor 12 to the multiple second wiping rollers 3 respectively, so as to drive the multiple second wiping rollers 3 to rotate.

[0043] Specifically, the second motor 12 is fixedly mounted on the other side of the frame 1, and the output end of the second motor 12 is connected to the second transmission component 13. The second transmission component 13 is also connected to multiple second wiping rollers 3.

[0044] In practical applications, when the second driving member 6 drives the multiple second wiping rollers 3 to rotate, it can drive the first driving member 5 to rotate. The rotating second driving member 6 then drives the multiple second wiping rollers 3 to rotate through the second transmission member 13.

[0045] It should be noted that the second motor 12 can be a frequency-modulated motor, which is a motor with adjustable speed. This frequency-modulated motor is existing technology, and no improvements or designs have been made to it, so its structure will not be described in detail.

[0046] Please see Figure 6 The second transmission component 13, used to transmit the rotational power of the second motor 12 to the plurality of second wiping rollers 3, includes a second drive sprocket 14, a plurality of second driven sprockets 15, and a second transmission chain 16; wherein, the second drive sprocket 14 is used to transmit the rotational power of the second motor 12 to the second transmission chain 16; the second transmission chain 16 is used to transmit the transmitted power to the plurality of spaced second driven sprockets 15; and the plurality of second driven sprockets 16 are used to transmit the power to the plurality of second wiping rollers 3.

[0047] Specifically, the second drive sprocket 14 is fixedly sleeved on the output shaft of the second motor 12. The second drive sprocket 14 is connected to multiple second driven sprockets 15 through the second transmission chain 16. Each second driven sprocket 15 is fixedly sleeved on the rotating shaft of each second wiping roller 3. The rotating shaft connected to each second wiping roller 3 is rotatably connected to the side wall of the frame 1. One end of the rotating shaft connected to the second wiping roller 3 does not extend out of the outer side wall of the frame 1, while the other end of the rotating shaft connected to the second wiping roller 3 extends out of the outer side wall of the frame 1.

[0048] In practical applications, when the second motor 12 drives multiple second wiping rollers 3 to rotate, the second motor 12 can be controlled to rotate by a controller connected to the second motor 12. The rotating second motor 12 drives the second drive sprocket 14 to rotate. Under the rotation of the second drive sprocket 14, the second transmission chain 16, which is connected to the second drive sprocket 14, drives multiple second driven sprockets 15 to rotate, indirectly driving the multiple second wiping rollers 3 sleeved with the second driven sprockets 15 to rotate.

[0049] It should be noted that, in order to avoid interference between the first wiping roller 2 and the second wiping roller 3 descending sequentially along the frame 1 and the bottom of the frame 1, the bottom of the frame 1 directly below the first wiping roller 2 and the second wiping roller 3 is inclined.

[0050] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
