[0002] During the processing of cigarette factories, an important process is to remove impurities from the tobacco before supply, and to remove the agglomerates and heavy impurities mixed in the tobacco, especially the heavy impurities. This further improves the process requirements of tobacco to ensure the quality of finished cigarettes. Domestic and foreign cigarette factories usually use wind suspension methods, and there have been many forms of wind separation and impurity removal equipment, but they all have problems such as low impurity removal rate, high tobacco crushing rate during the processing process, and large water loss, and the wind separation effect generally cannot achieve satisfactory results.

[0031] like Figures 1 to 7As shown, in this embodiment, it should be noted that this application document only aims to improve the existing cigarette making machines for the increasingly higher purity of incoming tobacco, the previous air separation and impurity removal equipment can no longer meet the needs of cigarette production, and the shortcomings of incomplete sorting and poor sorting effect in one-time air separation, and does not involve other aspects.

[0032] In addition, the sorting bin 3 in the application document has an overall size of 500*300*250, in addition to the above-mentioned sorting bin 3, circulating air supply box 2, circulating fan 6, impurity removal box assembly 4 and vibrating screen assembly 5; it also includes circulating air outlets with mesh plates on the left and right sides of the upper end of the sorting bin 3, and each air outlet is provided with an adjusting valve to control the air volume; a circulating fan 6 is arranged on the frame, and the circulating fan 6 is connected to the upper end of the circulating air outlet of the sorting bin 3, and the sorting bin 3 is provided with a feed pipe inclined upward at 60°, and the circulating fan 6 is used to generate circulating air, and the maximum air volume is 1600m3 / h; a discharge valve is arranged in the sorting bin 3, an air supply port is arranged below, and an air lock is arranged on the discharge valve;

[0033] After the device is assembled and before implementation, it is also matched with a coiling machine, the feed port of the sorting bin 3 is connected to the discharge end of the wire feeding machine, the discharge end of the wire feeding machine is connected to the suction port of the coiling machine, and a negative pressure detection device is installed at the discharge end of the wire feeding machine, the negative pressure detection device includes a negative pressure sensor and auxiliary devices, the negative pressure detection device is connected to the coiling machine and an external PLC controller, the above circuit connection is an existing circuit connection, the program setting and debugging can be performed before implementation, and it is not within the problem solved by this application;

[0034] During implementation, when the negative pressure detection device detects a negative pressure signal, the tobacco shreds enter the sorting bin 3 from the feed port of the sorting bin 3, and will float in the sorting bin 3. The heavier clumps and debris cannot be blown up and will fall onto the mesh plate at the bottom of the sorting bin 3, which is a 24-mesh screen. At the same time, the excitation motor 504 will drive the mesh plate to vibrate, and the mesh plate has a certain inclination. Under the vibration of the mesh plate, the heavier clumps and debris fall into the sorting bin 3 and are temporarily stored. When the tobacco shreds stop receiving materials, the air lock door on the discharge valve of the sorting bin 3 opens, so that the clumps, heavy debris, etc. fall into the debris collection box, thereby achieving the purpose of supplying and removing impurities.

[0035] When the negative pressure detection device detects that the suction end stops charging, the signal is transmitted to the external PLC controller. At this time, the external PLC controller controls to stop the circulation fan 6 and the exciting motor 504 to prevent the materials remaining in the pipeline from falling onto the vibration mesh plate and being cleaned up as debris after the charging stops. The structure is exquisite, and the installation, production and maintenance are relatively convenient. The product chamber has a good sealing effect, automatically detects the material demand, realizes automatic control, and has low energy consumption.
