Description

Technical Field

[0002] In the tobacco processing industry, the structure of the tobacco shreds after the drying process is subject to high requirements, and the length and quality of the conveyed tobacco shreds are key influencing factors. If the length of the dried tobacco shreds is too long, it can easily lead to unstable physical properties of the cigarette, such as large fluctuations in the draw resistance and weight of the cigarette, and an increase in the number of empty cigarettes to be discarded, resulting in wasted costs.

[0003] Furthermore, to meet the requirements of cigarette rolling, it is necessary to optimize the tobacco structure and reduce the proportion of long filaments. This is especially true for high-speed slim cigarette rolling machines, which have even higher requirements for tobacco structure. To improve the yield of slim cigarettes, additional equipment can be added to screen out long tobacco filaments and cut them shorter. However, setting up a separate production line for selecting and cutting long tobacco filaments would significantly increase production equipment, occupy a larger production area, and thus increase production costs.

[0037] Example 1

[0038] The tobacco shredding device provided in this application is used to shred dried tobacco shreds so that qualified tobacco shreds are conveyed to the main conveyor line. The main conveyor line includes a conveyor frame 1 and a conveyor belt 2, which is installed on the conveyor frame 1 to convey the tobacco shreds to the next process.

[0039] See Figures 1 to 4 As shown, the tobacco shredding device provided in this application includes a shredding mechanism and a conveying channel 16.

[0040] The material conveying channel 16 is spaced apart from the main conveying line, and the material conveying channel 16 is opposite to the loading end of the main conveying line. For example... Figure 2 and Figure 4 As shown, during the tobacco processing, when the quality of the dried tobacco is high, the tobacco does not need to be screened. In this case, the conveying channel 16 can directly transport the dried tobacco to the main conveying line, which can then directly transport the dried tobacco to the next process.

[0041] Furthermore, the screening mechanism is slidably disposed between the feeding channel 16 and the main conveying line; and when the screening mechanism is located between the feeding end and the feeding channel 16, the screening mechanism receives and screens the tobacco shreds from the feeding channel 16, and the screening discharge port of the screening mechanism is opposite to the main conveying line so that qualified tobacco shreds fall onto the main conveying line.

[0042] During the tobacco processing, when the quality of the dried tobacco is high, the screening mechanism is located away from the feeding end of the main conveyor line, so as not to affect the transportation of the tobacco. For example... Figure 1 and Figure 3 As shown, when the lengths of the dried tobacco shreds are uneven, the screening mechanism slides between the feeding channel 16 and the feeding end of the main conveyor line, so that the tobacco shreds output from the feeding channel 16 fall onto the screening mechanism. After screening by the screening mechanism, the shorter qualified tobacco shreds fall from the screening outlet onto the main conveyor line, so that the qualified tobacco shreds are directly conveyed to the next process; the longer unqualified tobacco shreds are conveyed from the feeding outlet of the screening mechanism to the cutting device, so that the cutting device can cut the tobacco shreds shorter.

[0043] The tobacco shredding screening device provided in this application places the screening mechanism between the conveying channel 16 and the main conveying line, without affecting the original layout of the main conveying line, reducing the floor space occupied by the screening mechanism, and effectively saving production space. Furthermore, the screening mechanism can be activated according to usage requirements. The device has high reliability and stability, and can efficiently complete the screening and conveying of tobacco shredding after drying, improving the efficiency of tobacco shredding conveying and thus further enhancing tobacco production efficiency.

[0044] In an optional embodiment, the material conveying channel 16 is provided with a telescopic part 17; the telescopic part 17 can extend or shorten so that the discharge port of the material conveying channel 16 is closer to or farther from the main conveying line.

[0045] In this embodiment, by extending or shortening the telescopic part 17, the distance between the discharge port of the conveying channel 16 and the main conveying line can be flexibly adjusted according to actual production needs, ensuring more precise material conveying. Specifically, when the quality of the dried tobacco is high, the screening mechanism is far from the feeding end of the main conveying line. At this time, the telescopic part 17 of the conveying channel 16 is extended so that the discharge port is closer to the main conveying line, allowing the tobacco at the discharge port to fall directly onto the main conveying line, reducing tobacco splashing and loss, and improving the accuracy of material conveying. When the length of the dried tobacco is uneven, the telescopic part 17 of the conveying channel 16 is shortened so that the discharge port is far from the main conveying line. At this time, a space is left between the conveying channel 16 and the main conveying line so that the screening mechanism can slide between the feeding end of the conveying channel 16 and the feeding end of the main conveying line, allowing the tobacco output from the conveying channel 16 to fall onto the screening mechanism.

[0046] Specifically, the telescopic part 17 is a stretchable fabric provided on the material conveying channel 16. The stretchable fabric is configured with an accordion pleat structure to make the structure of the material conveying channel 16 more stable.

[0047] In an optional embodiment, the tobacco shredding device further includes a frame; the frame includes a first side support 19 and a second side support 20, the first side support 19 and the second side support 20 being located on both sides of the main conveying line respectively; the two ends of the sieving mechanism are slidably mounted on the first side support 19 and the second side support 20.

[0048] In this embodiment, the screening mechanism includes a screening frame 3 and screening conveyor rollers 4. The screening conveyor rollers 4 are mounted on the screening frame 3 to screen and convey tobacco shreds. The gaps between the screening conveyor rollers 4 form a screening discharge port, through which shorter tobacco shreds fall onto the main conveyor line. The frame supports the screening mechanism at a certain height, positioning it above the main conveyor line, thus enabling the main conveyor line to receive the qualified tobacco shreds output by the screening mechanism.

[0049] Furthermore, by providing double-sided support to the screening mechanism via the first side bracket 19 and the second side bracket 20, the stability of the screening mechanism can be effectively improved, reducing vibration and offset caused by single-sided support. The screening mechanism is slidably mounted on the double-sided brackets, ensuring that it remains horizontal and stable during movement.

[0050] In an optional embodiment, the tobacco shredding device further includes a guide rail assembly; a guide rail assembly is provided between the shredding mechanism and the first side support 19 and the second side support 20; the guiding direction of the guide rail assembly is the transport direction of the main conveyor line; the guide rail assembly includes a slide rail and a slider slidably mounted on the slide rail, the slide rail is connected to the frame, and the slider is connected to the shredding mechanism.

[0051] In this embodiment, specifically, on the side of the screening mechanism, the slider connected to the end of the screening mechanism away from the feeding end is the first slider 7, and the screening mechanism is connected to the first slider 7 through the first connecting block 5. The slider connected to the end of the screening mechanism near the feeding end is the second slider 12, and the screening mechanism is connected to the second slider 12 through the second connecting block 13, which makes the connection between the screening mechanism and the guide rail assembly more stable.

[0052] The guide rail assembly ensures that the screening mechanism moves along the transport direction of the main conveyor line during sliding, allowing it to move above the main conveyor line without occupying extra space. The guide rail assembly improves the positioning accuracy of the screening mechanism and reduces positional deviation. The cooperative design of the slide rail and slider reduces vibration and swaying of the screening mechanism during movement, improving overall stability.

[0053] In an optional embodiment, the tobacco shredding device further includes a limiting component; the limiting component is connected to the frame, and the slider can abut against the limiting component to limit the sliding position of the shredding mechanism.

[0054] In this embodiment, such as Figures 1 to 4As shown, the main conveyor line and the screening mechanism are inclined, with the feeding end located at the lower end of the main conveyor line. When the screening mechanism slides downward to the feeding end, the second slider 12 connected to the screening mechanism abuts against the limiting component, thus limiting the screening mechanism to the feeding end and enabling precise acceptance of tobacco shreds. The limiting component ensures that the screening mechanism will not exceed the predetermined position range during sliding, improving positional accuracy and reducing positional deviation. The limiting component effectively prevents the screening mechanism from exceeding the safe range during movement, avoiding equipment damage or safety accidents caused by overtravel.

[0055] Specifically, the limiting component includes a connector 15 and a buffer 14; the connector 15 is connected to the frame, the buffer 14 is installed on the connector 15, and the second slider 12 can abut against the buffer 14 to provide elastic cushioning for the screening mechanism.

[0056] In this embodiment, the buffer 14 is specifically made of elastic silicone material. When the screening mechanism reaches its limit position, the buffer 14 provides elastic cushioning to reduce vibration and shaking caused by inertia, thereby improving overall stability. The buffer 14 helps to evenly distribute the force on the screening mechanism at its limit position, reducing stress concentration at single points and extending the service life of the equipment.

[0057] In an optional embodiment, the tobacco shredding device further includes a driving device; the driving device is mounted on the frame, and the driving end of the driving device is connected to the sieving mechanism to drive the sieving mechanism to reciprocate along the guiding direction of the guide rail assembly.

[0058] In this embodiment, the driving device is specifically a cylinder 10, and the piston rod 8 of the cylinder is connected to the first connecting block 5 above, thereby driving the first slider 7 to move along the slide rail. Figure 1 As shown, the cylinder 10 is located in the middle of the first side bracket 19, and the cylinder 10 occupies a certain space so that the slide rail is divided into an upper first slide rail 6 and a lower second slide rail 11. The first slider 7 is installed on the first slide rail 6, and the second slider 12 is installed on the second slide rail 11.

[0059] When cylinder 10 pushes the screening mechanism upwards, it provides a stable driving force, ensuring smooth reciprocating motion of the screening mechanism along the guide rail assembly. This reduces vibration and swaying caused by manual operation, improving overall stability. Furthermore, the drive unit can be integrated with an automated control system to achieve automatic reciprocating motion of the screening mechanism, reducing manual intervention and increasing the automation level of the production process. An automated screening mechanism can complete the screening and conveying of tobacco shreds more quickly and accurately, improving production efficiency and product quality.

[0060] In an optional embodiment, the tobacco shredding device further includes a mounting frame 9; the mounting frame 9 is connected to the frame, and the drive device is mounted on the mounting frame 9.

[0061] In this embodiment, to reduce the floor space, the top surface of the first side bracket 19 is relatively narrow, allowing only the guide rail assembly to be installed. However, the drive device requires a larger installation area. Therefore, this application connects the drive device and the frame by setting a mounting bracket 9. The mounting bracket 9 is specifically an L-shaped plate. One side of the mounting bracket 9 is connected to the side of the first side bracket 19 of the frame, and the other side of the mounting bracket 9 is used to install the drive device.

[0062] Example 2

[0063] The tobacco shredding device in this second embodiment is an improvement on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0064] See Figure 3 and Figure 4 As shown, in an optional embodiment, the tobacco shredding device further includes a receiving device 18; the receiving device 18 is located at the material feeding port of the shredding mechanism and is used to receive unqualified tobacco shredding material screened out by the shredding mechanism.

[0065] In this embodiment, the feeding port of the screening mechanism is located at the end of the screening mechanism away from the feeding end. The receiving device 18 is specifically a conveyor belt located at the feeding port. It can collect and transport the unqualified tobacco shreds screened out by the screening mechanism to the cutting device, so that the cutting device can cut the unqualified tobacco shreds into shorter pieces, realize the recycling of unqualified tobacco shreds, and reduce material waste.
