Description

Technical Field

[0001] This utility model relates to the field of tobacco stem separation technology, and more specifically, to a device for enhancing the screening effect of a secondary air classifier for tobacco shreds. Background Technology

[0002] In the process of making cigarettes, separating the tobacco stems from the tobacco is an essential step. If the tobacco stems are not removed, they are very likely to puncture the cigarette paper during the rolling process. Even if they don't puncture, it will still have a significant impact on the quality of the finished cigarettes.

[0003] However, current air separators are in an awkward situation where they cannot effectively balance the sieving effect of tobacco stems. Clumps of tobacco fall down along with the stems, resulting in a great deal of waste. If the air volume is increased to remove the clumps of tobacco, a large number of tobacco stems will not be sieved out, which will have a significant impact on the quality of the tobacco.

[0004] Therefore, there is an urgent need for a device to enhance the screening effect of a secondary air separator for tobacco shreds. Utility Model Content

[0005] The purpose of this invention is to provide a device that enhances the screening effect of a secondary air classifier for tobacco shreds, thereby solving the problems in the prior art. It can enhance the screening effect of tobacco stems in the secondary air classifier by breaking the tobacco shreds between the primary and secondary air classifiers.

[0006] This utility model provides a device for enhancing the screening effect of a secondary air separator for tobacco shreds, comprising: a head disposed between a primary air separator and a secondary air separator, wherein a first toothed roller and a second toothed roller are disposed inside the head, wherein the first toothed roller and the second toothed roller rotate in the same direction.

[0007] In the device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above, preferably, the first toothed roller and the second toothed roller rotate at the same speed.

[0008] In the device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above, preferably, a first conveyor belt 1 is provided between the machine head and the primary air classifier, and the first conveyor belt is located above one side of the machine head.

[0009] In the device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above, preferably, a second conveyor belt is provided between the machine head and the secondary air classifier, and the second conveyor belt is located below the other side of the machine head.

[0010] The device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above preferably further includes a speed controller for adjusting the speed of the first toothed roller and the second toothed roller.

[0011] In the device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above, preferably, the speed controller is located on one side of the second conveyor belt.

[0012] In the device for enhancing the screening effect of the secondary air classifier for tobacco shreds as described above, preferably, the speed controller is equipped with a low-speed control button, a medium-speed control button, and a high-speed control button.

[0013] This invention provides a device to enhance the screening effect of a secondary air classifier for tobacco shreds. It strengthens the screening effect of tobacco stems in the secondary air classifier by adding a head and a first and second toothed roller with the same rotation direction located between the primary and secondary air classifiers to break up the tobacco shreds. This enhances the screening capacity of the secondary air classifier without affecting the overall whole tobacco shred yield. It avoids the awkward situation where, with low airflow, clumps of tobacco shreds fall along with the stems, resulting in waste, and with high airflow, while clumps of tobacco shreds are removed, a large amount of stems remain unscreened, affecting the quality of the tobacco shreds. Simultaneously, it reduces waste of tobacco shreds and cigarette paper. Attached Figure Description

[0020] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0021] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0022] like Figure 1 As shown, the device for enhancing the screening effect of the secondary air separator for tobacco shreds provided in this embodiment includes: a head 2 disposed between the primary air separator and the secondary air separator, wherein a first toothed roller 3 and a second toothed roller 4 are disposed inside the head 2, wherein the first toothed roller 3 and the second toothed roller 4 rotate in the same direction.

[0023] The first toothed roller 3 and the second toothed roller 4 rotate at the same speed.

[0024] Furthermore, a first conveyor belt 1 is provided between the machine head 2 and the primary air separator, and the first conveyor belt 1 is located above one side of the machine head 2. A second conveyor belt 5 is provided between the machine head 2 and the secondary air separator, and the second conveyor belt 5 is located below the other side of the machine head 2.

[0025] During operation, the tobacco shreds are sieved by the primary air separator and conveyed to the machine head 2 via the first conveyor belt 1. Inside the machine head 2, the tobacco shreds fall onto the first toothed roller 3 and the second toothed roller 4, where they are broken up. Longer shreds are cut into shorter shreds to prevent them from clumping together again and affecting the secondary air separator's ability to screen for tobacco stems. The broken shreds fall onto the second conveyor belt 5, which then transports them to the secondary air separator. With no clumps remaining, the secondary air separator can further separate the tobacco shreds and stems, reducing or even eliminating the simultaneous sieving of clumps of tobacco shreds and stems. This enhances the secondary air separator's screening capacity, achieving more precise separation of tobacco shreds and stems, ensuring stem removal while avoiding tobacco waste, thus assisting in improving the screening effect of the secondary air separator.

[0026] Furthermore, the device for enhancing the screening effect of the secondary air classifier for tobacco shreds also includes a speed controller for adjusting the rotational speeds of the first toothed roller 3 and the second toothed roller 4. The speed controller is located on one side of the second conveyor belt 5. The speed controller is equipped with a low-speed control button 6, a medium-speed control button 7, and a high-speed control button 8. These three buttons control the rotational speeds of the first toothed roller 3 and the second toothed roller 4. By controlling the rotational speed, the tobacco shreds can be better dispersed according to the current tobacco flow rate, thereby enhancing the screening effect of the secondary air classifier and adapting to different tobacco flow rates. It should be noted that the process of controlling the rotational speeds of the first toothed roller 3 and the second toothed roller 4 through the speed controller and the low-speed, medium-speed, and high-speed control buttons 6 and 8 on the speed controller are all based on existing technologies. The purpose of this invention is to provide hardware-level improvements. In addition, it should be noted that this utility model does not specifically limit the number of gears in the speed controller or the correspondence between the gears and the speed.

[0027] The device for enhancing the screening effect of a secondary air classifier for tobacco shreds provided in this embodiment of the invention strengthens the screening effect of tobacco stems in the secondary air classifier by adding a head and a first toothed roller and a second toothed roller located within it, rotating in the same direction, between the primary and secondary air classifiers to break up the tobacco shreds. This enhances the screening capacity of the secondary air classifier without affecting the overall whole tobacco shred yield. It avoids the awkward situation where, with low airflow, clumps of tobacco shreds fall along with the tobacco stems, resulting in waste, and with high airflow, while clumps of tobacco shreds are removed, a large amount of tobacco stems remain unscreened, affecting the quality of the tobacco shreds. Simultaneously, it reduces waste of tobacco shreds and cigarette paper.
