The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention.

1 to 4, an embodiment of the present invention provides a residual smoke treatment device, which includes a transmission drum 100, a launch drum 200, a supercharger 500, a cutting channel 300, a blade 310 and a negative pressure recovery mechanism 400; wherein, A plurality of transmission grooves 110 are evenly arranged on the rolling surface of the transmission drum 100 ; a plurality of transmission channels 210 are evenly arranged on the rolling surface of the launch drum 200 , a transmission position 120 and a transmission groove 110 are arranged between the transmission drum 100 and the launch drum 200 . The residual smoke 700 in the transmission position 120 is transferred to the emission channel 210 corresponding to the transmission position 120; the output end of the supercharger 500 is aligned with the emission channel 210 at the set position on the emission drum 200; the cutting channel 300 is The firing channel 210 at the set position on the firing drum 200 is aligned, and the cutting channel 300 and the booster 500 are located on both sides of the firing drum 200; An incision is cut on the paper; the negative pressure recovery mechanism 400 is arranged at the outlet of the cutting channel 300, and is used for attracting the shredded tobacco in the cigarette paper from the incision.

Wherein, the transmission drum 100 can be arranged above the launch drum 200, and there is a gap between the transmission drum 100 and the launch drum 200. The position of the gap is the above-mentioned transmission position 120. When the residual smoke 700 is transported to the transmission drum 100 , the residual smoke 700 can enter the transmission slot 110. With the continuous rotation of the transmission drum 100, the residual smoke 700 can be transported to the transmission position 120 along with the transmission slot 110. The residual smoke 700 reaching the transmission position 120 can leave the transmission slot 110 and enter the In the transmit channel 210 corresponding to the transmission bit 120 . The firing channel 210 can transmit the residual smoke 700 to the position where the supercharger 500 is aligned with the rotation of the firing drum 200, namely the firing position 230. The residual smoke 700 is blown towards the cutting channel 300. Since the cutting channel 300 is provided with a blade 310 and the cutting edge 311 of the blade 310 faces the cigarette of the residual smoke 700, when the cigarette passes through the blade 310, the cigarette paper of the cigarette can be cut out by the blade 310 A cut, which may extend from the end of the cigarette to the filter rod. The cut residual smoke 700 will continue to be blown by the high-pressure air to the negative pressure recovery mechanism 400. The negative pressure recovery mechanism 400 can absorb the cut tobacco from the cut on the cigarette to the recovery equipment, while the filtered tobacco is sucked away. Sticks and cigarette papers are dropped into scrap recycling facilities.

Wherein, when the residual smoke 700 in the firing channel 210 of the firing position 230 is blown out into the cutting channel 300, the firing drum 200 rotates to turn the next firing channel 210 containing the residual smoke 700 to the firing position 230 without losing the The emission channel 210 of the residual smoke 700 rotates toward the transmission position 120 to receive the next residual smoke 700 , thereby realizing the continuous operation of the residual smoke 700 .

Compared with the prior art, the residual smoke treatment device provided by the embodiment of the present invention replaces the existing method of multiple beating and multi-stage screening, and adopts the method of sending the residual smoke 700 by air and absorbing shredded tobacco by negative pressure. The mixing degree of the cut tobacco, the cigarette paper and the filter rod during the separation process is effectively reduced, the crushing caused by the separation is reduced, and the recovery rate and purity of the cut tobacco are improved.

It should be noted that, in order to prevent the residual smoke 700 from falling before being transferred to the transfer position 120 , a baffle plate may be provided on the periphery of the transmission drum 100 , and the baffle plate may be an arc-shaped matching with the rolling surface of the transmission drum 100 . According to the structure, before the residual smoke 700 is transmitted to the transfer position 120, the residual smoke 700 can be blocked by a baffle to prevent it from falling.

Further, there may be more than two blades 310 , the two or more blades 310 are evenly distributed on the inner wall of the cutting channel 300 , and the maximum distance between the cutting edges 311 of the two or more blades 310 is smaller than the diameter of the residual smoke 700 .

When the residual smoke 700 is output from the emission channel 210, the residual smoke 700 can pass between the cutting edges 311 of each blade 310, so that the cutting edges 311 can make a cut on the cigarette paper. The center of the exit of the emission channel 210 is collinear with the center of the cutting channel 300, and the diameter of the emission channel 210 is slightly larger than the maximum distance between the cutting edges 311 of the blades 310, so as to ensure that when the residual smoke 700 is blown out of the emission channel 210, it can be Cuts are made between the blades 310 . In this embodiment, the number of blades 310 is preferably four.

Further, the device further includes a vibrating screen 600 , the vibrating screen 600 is arranged at the outlet of the cutting channel 300 , and the recovery direction of the negative pressure recovery mechanism 400 is perpendicular to the surface of the vibrating screen 600 .

When the residual smoke 700 is output from the cutting channel 300, the residual smoke 700 can be dropped onto the vibrating screen 600, and the vibrating screen 600 can vibrate the shredded tobacco in the cigarette paper from the cigarette paper, so that the upper negative pressure recovery mechanism 400 adsorption recovery.

Further, the negative pressure recovery mechanism 400 includes a pneumatic pump, a recovery pipeline 410 and a recovery cover 420. The pneumatic pump is connected to one end of the recovery pipeline 410, and the other end of the recovery pipeline 410 is connected to the recovery cover 420. The recovery cover 420 is trumpet-shaped .

Among them, the trumpet-shaped recovery cover 420 can expand the receiving range of shredded tobacco and improve the adsorption and recovery efficiency.

Further, the negative pressure recovery mechanism 400 further includes a filter structure, and the filter structure is arranged in the recovery cover 420 or in the recovery pipeline 410, so as to effectively suppress the mixing of filter rod dust and paper scraps into the shredded tobacco.

Further, the device further includes a smoke-blocking casing 220 , and the smoke-blocking casing 220 is in clearance fit with a part of the rolling surface of the firing drum 200 .

During the process of delivering the residual smoke 700 in the firing channel 210 to the firing position 230 by the firing drum 200 , if the firing channel 210 is rotated more than 90°, the residual smoke 700 may fall prematurely due to the downward slope of the opening of the firing channel 210 . For this purpose, the smoke-blocking housing 220 can be blocked on the firing drum 200 where the residual smoke 700 is likely to fall before being transported to the firing position 230 .

The residual smoke treatment device provided by the embodiment of the present invention replaces the existing method of multiple beating and multi-stage screening, and adopts the method of sending residual smoke by air and absorbing shredded tobacco by negative pressure, which effectively reduces the amount of tobacco shredded, cigarette paper, filter and shredded tobacco. The degree of mixing in the rod separation process reduces the fragmentation generated by the separation and improves the recovery rate and purity of the cut tobacco.
