Description

Technical Field

[0001] This utility model relates to the field of cigarette processing technology, and in particular to a tobacco leaf shredding device. Background Technology

[0002] In the cigarette production process, tobacco leaf shredding is a core step that determines the quality of tobacco shreds and the efficiency of subsequent cigarette processing. Its processing effect directly affects the combustion performance, taste consistency, and raw material utilization of cigarettes. Currently, tobacco leaf shredding equipment uses a cutter roller to cut the tobacco leaves and then directly conveys them to the next station. However, due to the fiber characteristics of the tobacco leaves themselves and the local temperature changes during the cutting process, the tobacco shreds are very prone to sticking together during the conveying process. This not only leads to uneven tobacco filling density in the subsequent rolling process, but also causes significant differences in the taste of the finished cigarettes, seriously affecting the stability of product quality. At the same time, during the tobacco leaf cutting process, some fine tobacco shreds will become entangled in the gap between the blades of the cutter roller due to the adsorption force or fiber hooking effect generated by the high-speed rotation of the cutter roller. If not cleaned in time, it will cause the actual cutting width of the blades to shrink and the shearing force to decrease, which will lead to precision problems such as excessively fine shreds and incomplete shredding. This will not only produce a large number of unqualified broken shreds, causing waste of raw materials, but also increase the running resistance of the cutter roller shaft due to the accumulation of tobacco shreds. Long-term use is prone to cutter roller shaft failure, increasing equipment maintenance costs and the frequency of downtime for maintenance.

[0003] Therefore, there is an urgent need for a tobacco leaf shredding device to solve the aforementioned problems. Utility Model Content

[0014] As a preferred technical solution for a tobacco leaf shredding device, the first drive assembly includes a connecting cover, a second motor, a synchronous belt, and two synchronous pulleys.

[0024] This utility model provides a tobacco leaf shredding device. During the shredding process, the tobacco leaves are conveyed into the feeding trough and fall onto the conveying device. The conveying device transports the tobacco leaves along a first direction. As the leaves pass through the grinding device, a first drive assembly drives a first pressure roller to rotate, which then rolls the tobacco leaves on the conveying device. The first pressure roller first performs a pre-treatment by grinding the tobacco leaves, flattening and smoothing out any curled or clumped leaves. Following this, the pre-treated tobacco leaves continue to move with the conveying device and are conveyed to the area below the shredding device, where a second drive assembly drives a cutter roller to rotate. The cutting roller cuts the flattened tobacco leaves into shredded tobacco of the required specifications. The cut shredded tobacco is then conveyed by a conveyor into the turning device. A third drive assembly drives the turning roller to rotate. As the turning roller rotates, it tumbles the cut shredded tobacco, breaking up any clumps to improve its looseness. Simultaneously, it scrapes off any tobacco tangled on the cutting roller, preventing accumulation and ensuring the cutting device's subsequent operation is not affected. This completes the entire processing flow of tobacco leaves, from feeding, conveying, pre-treatment, cutting to post-processing. This invention, by incorporating the turning roller, prevents tobacco shreds from tangling on the cutting roller, improving the processing quality of the tobacco and extending the lifespan of the cutting roller, while reducing equipment maintenance costs and downtime for repairs.

[0041] like Figure 1 and Figure 2As shown, this embodiment provides a tobacco leaf shredding device, which includes a base 1, a conveying device 2, a grinding device 3, a shredding device 4, and a turning device 5. The base 1 is provided with a feeding trough 11; one end of the conveying device 2 is connected to the downstream of the feeding trough 11, and the conveying device 2 is used to convey tobacco leaves along a first direction; the grinding device 3, the shredding device 4, and the turning device 5 are sequentially arranged above the conveying device 2 along the first direction. The grinding device 3 is located near the end of the feeding trough 11, and the grinding device 3 includes a first driving assembly 31 and a first pressure roller 32. The first driving assembly 31 drives... A first pressure roller 32 is connected to and used to drive the first pressure roller 32 to rotate. The first pressure roller 32 is used to roll and press the tobacco leaves on the conveying device 2. The shredding device 4 includes a second drive assembly 41 and a cutting roller 42. The second drive assembly 41 drives and connects to the cutting roller 42 to rotate. The cutting roller 42 is used to cut the tobacco leaves on the conveying device 2. The turning device 5 includes a third drive assembly 51 and a turning roller 52. The third drive assembly 51 drives and connects to the turning roller 52 to rotate. The turning roller 52 is used to scrape off the tobacco shreds on the cutting roller 42 and turn the cut tobacco shreds. In this embodiment, the first direction is X, the second direction is Y, and the first direction is perpendicular to the second direction.

[0042] During the shredding process of tobacco leaves, the tobacco leaves are conveyed into the feed trough 11 and fall onto the conveying device 2. The conveying device 2 conveys the tobacco leaves along the first direction. When passing the grinding device 3, the first drive assembly 31 drives the first pressure roller 32 to rotate, and the first pressure roller 32 rolls the tobacco leaves on the conveying device 2. The first pressure roller 32 first performs a pre-treatment of the tobacco leaves by crushing and flattening the curled and clumped tobacco leaves. Then, the pre-treated tobacco leaves continue to move with the conveying device 2 and are conveyed to the area below the shredding device 4. The second drive assembly 41 drives the cutter roller 42 to rotate, and the cutter roller 42 will... The flattened tobacco leaves are cut into shreds of the required specifications. The cut shreds are then conveyed by the conveyor 2 into the working range of the turning device 5. The third drive assembly 51 drives the turning roller 52 to rotate. As the turning roller 52 rotates, it tumbles the cut shreds, breaking up any clumps to improve their looseness. Simultaneously, it scrapes off any shreds wrapped around the cutting roller 42, preventing accumulation and ensuring the cutting device 4 doesn't interfere with subsequent operations. This completes the entire processing flow of tobacco leaves, from feeding, conveying, pre-treatment, cutting to post-processing. This invention, by incorporating the turning roller 52, prevents shreds from tangling on the cutting roller 42, improving the processing quality of the shreds, extending the service life of the cutting roller 42, and reducing equipment maintenance costs and downtime for repairs.

[0043] like Figure 3As shown, in this embodiment, the conveying device 2 includes a drive roller 21, a driven roller 22, a conveyor belt 23, and a first motor 24. The drive roller 21 and the driven roller 22 are rotatably connected to the base 1 and are spaced apart along a first direction. One end of the conveyor belt 23 is wound around the drive roller 21, and the other end is wound around the driven roller 22. The first motor 24 is mounted on the base 1 and is driven and connected to the drive roller 21. When the conveying device 2 needs to be started, the first motor 24 is started. The output power of the first motor 24 will drive the drive roller 21 connected to it to rotate. The drive roller 21 drives the conveyor belt 23 to move. The driven roller 22 rotates through the friction of the conveyor belt 23, thereby realizing the cyclic movement of the conveyor belt 23. At this time, the tobacco leaves that slide from the feed trough 11 onto the conveyor belt 23 can be stably conveyed to the subsequent grinding device 3, shredding device 4, and turning device 5 with the cyclic movement of the conveyor belt 23.

[0044] Preferably, the conveying device 2 further includes a plurality of support rollers 25 rotatably connected to the base 1. The plurality of support rollers 25 are spaced apart between the drive roller 21 and the driven roller 22 along the first direction. The plurality of support rollers 25 can form an upward support force on the inner side of the conveyor belt 23, effectively preventing the conveyor belt 23 from collapsing or sagging due to the weight of the tobacco leaves or its own long length, ensuring that the conveyor belt 23 always maintains a flat conveying state, ensuring that the tobacco leaves do not deviate or accumulate during the transmission process, and flow stably to the subsequent processing stage, while also facilitating the subsequent shredding.

[0045] In this embodiment, the feed chute 11 is an inclined chute with an inclined surface 111, and the conveyor belt 23 is connected to the bottom end of the inclined surface 111. The tobacco leaves enter the inclined chute and can automatically slide onto the conveyor belt 23.

[0046] like Figure 4 As shown, preferably, the grinding device 3 further includes a second pressure roller 33. The first drive assembly 31 is connected to the second pressure roller 33 and is used to drive the second pressure roller 33 to rotate. The second pressure roller 33 is located on the side of the first pressure roller 32 near the shredding device 4. By using both the first pressure roller 32 and the second pressure roller 33 to perform grinding pretreatment on the tobacco leaves, the pretreatment effect of the tobacco leaves is improved.

[0047] More preferably, the distance between the first pressure roller 32 and the conveying device 2 (i.e., the conveyor belt 23) is greater than the distance between the second pressure roller 33 and the conveying device 2. The tobacco leaves conveyed by the conveyor belt 23 to the area below the connecting cover 311 will first be initially stretched under the first pressure roller 32, and then further crushed and flattened under the second pressure roller 33, in preparation for the subsequent shredding process.

[0048] In this embodiment, the first drive assembly 31 includes a connecting cover 311, a second motor 312, a synchronous belt 313, and two synchronous pulleys 314. The connecting cover 311 is connected to the machine base 1 and covers the conveying device 2. The first pressure roller 32 and the second pressure roller 33 are rotatably connected to the connecting cover 311. The second motor 312 is connected to the connecting cover 311 and drives one end of the first pressure roller 32. One synchronous pulley 314 is disposed at the other end of the first pressure roller 32, and the other synchronous pulley 314 is disposed at one end of the second pressure roller 33. The two ends of the synchronous belt 313 are respectively wound around the two synchronous pulleys 314. When the grinding device 3 is working, the second motor 312 is started. The output power of the second motor 312 will directly drive the first pressure roller 32, which is rotatably connected to the connecting cover 311, to rotate. Since one end of the first pressure roller 32 is fixedly connected to one of the synchronous pulleys 314, and the two synchronous pulleys 314 are respectively fixed to one end of the first pressure roller 32 and the second pressure roller 33, and the power is transmitted through the synchronous belt 313 sleeved on them, when the first pressure roller 32 rotates, it will drive the synchronous pulley 314 at one end of it to rotate synchronously. The synchronous pulley 314 will drive the synchronous pulley 314 at one end of the second pressure roller 33 to rotate through the synchronous belt 313, thereby making the second pressure roller 33 and the first pressure roller 32 rotate synchronously.

[0049] like Figure 5 As shown, further, the sidewall of the cutter roller 42 is provided with a plurality of blades 421 spaced apart along the second direction, and a gap is provided between adjacent blades 421; therefore, the sidewall of the turning roller 52 is provided with a plurality of sweeping teeth 521, and the ends of the sweeping teeth 521 are positioned directly opposite the gaps. In order to reduce the entanglement of cut tobacco on the cutter roller 42, the end of the sweeping tooth 521 away from the turning roller 52 is located in the gap between two adjacent blades 421, and the sweeping tooth 521 does not contact the surface of the cutter roller 42; the end of the sweeping tooth 521 away from the turning roller 52 extends into the gap between adjacent blades 421, and can directly scrape off the tobacco entangled in the gap, so that the tobacco cannot be entangled on the cutter roller 42, thereby reducing the cutting jamming or decrease in accuracy caused by the accumulation of material in the gap between the blades 421. In addition, the sweeping tooth 521 does not contact the surface of the cutter roller 42, which can eliminate the component wear caused by friction between the two, reduce equipment maintenance costs, and extend the service life of the equipment.

[0050] To ensure the effectiveness of the sweeping tooth 521 extending into the gap between the blades 421, preferably, the diameter of the sweeping tooth 521 gradually decreases along the direction away from the axis of the turning roller 52. The diameter of the sweeping tooth 521 near the gap between the blades 421 is smaller, which can reduce the contact area with the blades 421, thereby reducing the frictional resistance during insertion and movement and avoiding jamming. The diameter of the end near the turning roller 52 is larger, which can increase the structural load-bearing capacity and prevent the sweeping tooth 521 from bending and deforming due to the force of the tobacco during turning.

[0051] In this embodiment, the second drive assembly 41 includes a fixed cover 411 and a third motor 412. The fixed cover 411 is connected to the base 1 and covers the conveying device 2. The cutter roller 42 is rotatably connected to the fixed cover 411. The third motor 412 is connected to the fixed cover 411 and drives one end of the cutter roller 42. The third drive assembly 51 includes two gears 511. One gear 511 is located at the other end of the cutter roller 42, and the other gear 511 is located at one end of the turning roller 52. The two gears 511 are meshed together.

[0052] When the third motor 412 in the shredding device 4 drives the cutting roller 42 to rotate, one of the gears 511 is fixedly connected to one end of the cutting roller 42 and is located on the side of the fixed cover 411 away from the third motor 412. The cutting roller 42 will synchronously drive the gear 511 to rotate. Since the two gears 511 mesh with each other, and the other gear 511 is fixedly connected to one end of the turning roller 52, the rotating gear 511 will drive the other gear 511 to rotate in the opposite direction through meshing transmission. The other gear 511 is fixedly connected to the turning roller 52, thereby driving the turning roller 52 and the cutting roller 42 to rotate in opposite directions. Finally, the turning roller 52 and the cutting roller 42 are linked to operate. This ensures that the palladium frame on the turning roller 52 can tumble and disperse the tobacco shreds cut by the cutting roller 42 in time, and simultaneously clean the tobacco shreds wrapped in the gap of the blade 421, so that the turning action and the shredding action are precisely coordinated.

[0053] like Figure 1 As shown, in this embodiment, the drive roller 21, driven roller 22, support roller 25, first pressure roller 32, second pressure roller 33, cutter roller 42 and turning roller 52 all extend along the second direction.

[0054] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
