Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco processing technology, and in particular to a loosening device. Background Technology
[0002] In the production process of cigarette products, tobacco leaves that meet the process specifications are usually prepared in the tobacco processing workshop. Specifically, after the tobacco leaves are dried and shaped in the re-drying plant, they are sent to the tobacco processing workshop. Then, the tobacco leaves go through processes such as dismantling the tobacco boxes in the re-drying plant, cutting the tobacco leaves into uniform tobacco sheets, loosening and re-moistening, and adding flavorings and ingredients, so that the tobacco leaves are transformed into tobacco leaves that meet the production process of the cigarette packaging workshop.
[0003] In related technologies, in the tobacco processing workshop, after the large re-dried tobacco blocks are cut into pieces that meet the requirements of the loosening and re-moistening process through the slicing process, the tobacco blocks are cut into small pieces of a fixed length and width, and transported to the loosening and re-moistening process by conveyor belt. In related technologies, the loosening effect of tobacco leaves after being cut is not good. Usually, manual methods are used to pre-loosen the small tobacco pieces after slicing. However, manual pre-loosening is time-consuming and labor-intensive, and the loosening quality is difficult to meet the requirements. Utility Model Content
[0004] Therefore, it is necessary to propose a loosening device to address the problems of the current manual pre-loosening being time-consuming and labor-intensive, and the loosening quality being difficult to meet the requirements.
[0005] A loosening device, comprising:
[0006] A transmission mechanism includes a transmission element and a transmission belt. The transmission element includes a plurality of transmission rollers arranged along a first direction, each of the transmission rollers extending along a second direction and configured to rotate about its own axis. The transmission belt is wound around the plurality of transmission rollers and configured to move along the first direction under the drive of the transmission rollers.
[0007] A loosening mechanism is located on either side of the conveyor belt away from the drive roller along a third direction. The loosening mechanism is spaced apart from the conveyor belt and includes a plurality of loosening components arranged along a second direction. Each loosening component includes a first drive member and a loosening blade. The loosening blade is connected to the drive end of the first drive member, and the first drive member is configured to drive the loosening blade to move closer to or away from the conveyor belt along the third direction. The first direction, the second direction, and the third direction are arranged in pairs.
[0008] In one embodiment, the loose component includes a second drive member, the fixed end of the first drive member being connected to the drive end of the second drive member, the second drive member being configured to drive the first drive member to rotate about an axis parallel to the third direction.
[0009] In one embodiment, the loosening device includes an image acquisition device located on the side of the conveyor belt near the loosening mechanism and spaced apart from the conveyor belt;
[0010] The image acquisition device is configured to acquire image information of the side of the conveyor belt near the loose mechanism; both the first drive unit and the second drive unit are communicatively connected to the image acquisition device.
[0011] In one embodiment, the loosening device includes a control unit, and the first drive unit, the second drive unit, and the image acquisition unit are all communicatively connected to the control unit.
[0012] In one embodiment, the loose assembly includes a mounting bracket, and the fixed end of the second drive member is connected to the mounting bracket.
[0013] In one embodiment, the transmission mechanism includes two baffles extending along the first direction, the two baffles being located on opposite sides of the transmission belt in the second direction.
[0014] In one embodiment, the mounting bracket includes a crossbeam and two support columns, the crossbeam extending along the second direction; the support columns extending along the third direction, the two support columns being located on opposite sides of the crossbeam in the second direction;
[0015] The two support columns are arranged in a one-to-one correspondence with the two baffles, and each support column is connected to the corresponding baffle.
[0016] In one embodiment, the loosening device includes a mounting frame to which the image acquisition device is connected and configured to rotate relative to the mounting frame about an axis parallel to the second direction.
[0017] In one embodiment, the fixing frame includes a truss and a column, the truss extending along the second direction, the column extending along the third direction, the column being located on one side of the truss in the second direction and connected to the truss;
[0018] The image acquisition unit is rotatably connected to the truss and is configured to rotate about an axis parallel to the second direction.
[0019] In one embodiment, the transmission mechanism includes a third drive member, the drive end of which is connected to any of the transmission rollers and configured to drive the corresponding transmission roller to rotate.
[0020] In this embodiment of the loosening device, the tobacco blocks to be loosened are located on the side of the conveyor belt along a third direction closer to the loosening mechanism. The drive roller rotates around its own axis, and the conveyor belt moves along a first direction under the drive of the drive roller, synchronously moving the tobacco blocks to be loosened until they reach the side of the loosening mechanism along a third direction closer to the conveyor belt. At this point, the first drive member drives the loosening blade along a third direction closer to the conveyor belt to cut the tobacco blocks on the conveyor belt, making them looser. After cutting the tobacco blocks, the first drive member drives the loosening blade away from the conveyor belt along the first direction, returning the loosening blade to its initial state. Subsequently, the drive roller continues to rotate around its own axis, further driving the conveyor belt to move along the first direction until the cut tobacco blocks on the conveyor belt are transferred to the next process.
[0021] Throughout the entire process described above, the movement of the loosening knife is automatically driven by the first driving component. The loosening knife is fully automated in the process of loosening the tobacco blocks to be loosened, without the need for manual intervention, saving time and effort, ensuring controllable quality, and meeting the loosening requirements.
[0022] In summary, the loosening device in this embodiment can automatically loosen the tobacco blocks without manual intervention, saving time and effort, ensuring controllable quality, and meeting the loosening requirements. Attached Figure Description

[0037] Please see Figure 1 , Figure 1 A schematic diagram of a loosening device according to an embodiment of this application is shown. An embodiment of this application provides a loosening device 1, comprising: a transmission mechanism 10 and a loosening mechanism 20. The transmission mechanism 10 includes a transmission member 110 and a transmission belt 120. The transmission member 110 includes a plurality of transmission rollers 111 arranged along a first direction. Each transmission roller 111 extends along a second direction and is configured to rotate about its own axis. The transmission belt 120 is wound around the plurality of transmission rollers 111 and is configured to move along the first direction under the drive of the transmission rollers 111. The loosening mechanism 20 is located at the transmission mechanism 10. The conveyor belt 120 is located on any side of the third direction away from the drive roller 111. The loosening mechanism 20 is spaced apart from the conveyor belt 120. The loosening mechanism 20 includes a plurality of loosening components 210 arranged along the second direction. The loosening component 210 includes a first drive member 211 and a loosening blade 212. The loosening blade 212 is connected to the drive end of the first drive member 211. The first drive member 211 is configured to drive the loosening blade 212 to approach or move away from the conveyor belt 120 along the third direction. The first direction, the second direction and the third direction are arranged in pairs.
[0038] In this embodiment, the loosening device 1 has the tobacco blocks to be loosened located on the side of the conveyor belt 120 along a third direction, closer to the loosening mechanism 20. The drive roller 111 rotates around its own axis, and the conveyor belt 120 moves along a first direction under the drive of the drive roller 111, driving the tobacco blocks to be loosened to move synchronously until the tobacco blocks move to the side of the loosening mechanism 20 along a third direction, closer to the conveyor belt 120. At this time, the first drive member 211 drives the loosening blade 212 along a third direction towards the conveyor belt 120 to cut the tobacco blocks on the conveyor belt 120, making the tobacco blocks looser. After cutting the tobacco blocks, the first drive member 211 drives the loosening blade away from the conveyor belt 120 along the first direction, so that the loosening blade 212 returns to its initial state. Subsequently, the drive roller 111 continues to rotate around its own axis, further driving the conveyor belt 120 to move along the first direction until the cut tobacco blocks on the conveyor belt 120 are transferred to the next process. Throughout the entire process described above, the movement of the loosening knife 212 is automatically driven by the first driving component 211. The loosening knife 212 is fully automated in the process of loosening the tobacco blocks to be loosened, without the need for manual intervention, saving time and effort, ensuring controllable quality, and meeting the loosening requirements.
[0039] In summary, the loosening device 1 in this embodiment can automatically loosen the tobacco blocks without manual intervention, saving time and effort, ensuring controllable quality, and meeting the loosening requirements.
[0040] Please see Figure 1 In some embodiments, the loose component 210 includes a second drive member 213, with the fixed end of the first drive member 211 connected to the drive end of the second drive member 213, and the second drive member 213 configured to drive the first drive member 211 to rotate about an axis parallel to a third direction.
[0041] In this embodiment, after the first driving member 211 drives the loosening blade 212 to cut the tobacco block to be loosened, the second driving member 213 will drive the first driving member 211 to rotate around an axis parallel to the third direction, so as to drive the loosening blade 212 to move synchronously, thereby causing the loosening blade 212 to pry the tobacco block to be cut and loosened until the tobacco block to be cut and loosened is dispersed to the target looseness.

[0043] In this embodiment, the image acquisition device 30 will acquire image information of the side of the conveyor belt 120 close to the loosening mechanism 20 in real time, and transmit the captured data to the first driving member 211 and the second driving member 213. On the one hand, it is convenient for the first driving member 211 to accurately drive the loosening knife 212 close to the conveyor belt 120 when the smoke block to be loosened moves to the side of the loosening mechanism 20 close to the conveyor belt 120 in a third direction. On the other hand, it is convenient for the second driving member 213 to stop driving the loosening knife 212 after the loosening knife 212 has dispersed the smoke block to be loosened to the target looseness.

[0050] In this embodiment, the support column 220-2 supports the crossbeam 220-1, so that the crossbeam 220-1 and the conveyor belt 120 are arranged at intervals along a third direction.
[0051] Please see Figure 1In some embodiments, the loosening device 1 includes a mounting frame 40, to which the image acquisition device 30 is connected and configured to rotate relative to the mounting frame 40 about an axis parallel to the second direction.
[0052] In this embodiment, by driving the image acquisition device 30 to rotate relative to the fixed frame 40 around an axis parallel to the second direction, the position and orientation of the image acquisition device 30 can be adjusted, thereby facilitating the image acquisition device 30 to better acquire image information of the side of the conveyor belt 120 close to the loose mechanism 20.
[0053] Please see Figure 1 In some embodiments, the mounting frame 40 includes a truss 410 and a column 420, the truss 410 extending along a second direction and the column 420 extending along a third direction, the column 420 being located on one side of the truss 410 in the second direction and connected to the truss 410; the image acquisition unit 30 is rotatably connected to the truss 410 and is configured to rotate about an axis parallel to the second direction.
[0054] Please see Figure 1 In some embodiments, the transmission mechanism 10 includes a third drive member (not shown in the figure), the drive end of which is connected to any of the transmission rollers 111 and is configured to drive the corresponding transmission roller 111 to rotate.
[0055] In this embodiment, the third driving member drives the corresponding transmission roller 111 to rotate, so that the transmission roller 111 drives the transmission belt 120 to move along the first direction.
[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
