Abstract
Description
Technical Field
[0001] The utility model relates to the field of screening equipment, in particular to a tobacco sheet electrostatic impurity removal device. Background Art
[0002] During the tobacco leaf threshing and redrying process, the raw tobacco often contains some light non-tobacco substances, such as feathers, dust, hemp, weeds, etc. These impurities not only affect the quality of the tobacco leaves, but may also cause wear or damage to subsequent production equipment. Moreover, such non-tobacco substances are not easy to remove by conventional means. Therefore, it is particularly important to remove light non-tobacco substances during the tobacco leaf threshing and redrying process.
[0003] Traditional methods of removing impurities from tobacco leaves mainly include mechanical screening, airflow separation, and photoelectric sorting. Although these methods can remove impurities from tobacco leaves to a certain extent, they still have some shortcomings. Mechanical screening can easily damage the tobacco leaves, affecting the quality of the final product; airflow separation requires a relatively high balanced and controllable wind field, but the separation effect is not good for some smaller impurities or impurities with a density similar to that of tobacco leaves; photoelectric sorting uses chromatographic identification, which requires a high equipment cost and has poor applicability for non-tobacco substances with a color similar to that of tobacco leaves. In addition, the efficiency of traditional manual impurity removal methods is also relatively low, and it is even less efficient for light non-tobacco substances, especially when faced with large-scale production needs, it is difficult to remove impurities quickly and efficiently.

[0026] To describe the technical content, achieved purpose and effect of the present utility model in detail, the following is described in conjunction with the implementation mode and accompanied by the drawings.
[0027] Please refer to Figures 1 to 3 , an electrostatic impurity removal device for tobacco flakes, comprising an electrostatic roller assembly 1, an impurity removal assembly 2 and a dust suction assembly 3; the electrostatic roller assembly 1 includes at least one electrostatic roller 11 and an electrostatic field control part, and the electrostatic field control part is used to adjust the voltage and current on the electrostatic roller 11; the impurity removal assembly 2 includes a scraping plate 21 and a collection part 22, the scraping plate 21 is connected to the collection part 22, the scraping plate 21 abuts against the circumferential surface of the electrostatic roller 11, and the dust suction assembly 3 is arranged in the collection part 22, and the dust suction assembly 3 is used to clean the impurities in the collection part 22.

The dust suction assembly 3 further cleans the impurities in the collection part 22, ensuring the continuous and efficient operation of the device.
[0029] Furthermore, the dust suction assembly 3 includes a dust suction nozzle 31 and a slide rail 32, and the dust suction nozzle 31 is slidably connected to the slide rail 32; the collection part 22 is a collection groove, and the slide rail 32 is arranged parallel to the length direction of the collection groove.
[0030] As described above, the dust collection component 3 adopts a connection method with a slide rail 32, enabling the dust suction nozzle 31 to move smoothly within the collection trough, ensuring that impurities can be fully removed and avoiding the possibility of residue. The design of the slide rail 32 is parallel to the length direction of the collection trough, making the dust suction operation more convenient and effective.
[0031] Specifically, the slide rail 32 is a rodless cylinder, and the dust suction nozzle 31 is mounted on the rodless cylinder and moves with the cylinder to complete the cleaning of the entire collection trough.
[0032] Furthermore, the dust collection component 3 further includes a cyclone separator 33, a negative pressure generator 34, and a dust collection bucket 35.

[0042] Furthermore, the device further includes a central controller, which is used to obtain the sensing data of the temperature sensor and the humidity sensor, and adjust the output voltage and current of the electrostatic field control unit according to the sensing data.

[0045] As can be seen from the above description, the bracket 5 design of the housing 4 ensures the stability of the device, and at the same time makes the height adjustment of the first chamber 41 and the second chamber 42 more flexible, so as to adapt to different usage environments and requirements.
[0046] Specifically, the first chamber 41 and the second chamber 42 are arranged at the top of the bracket 5, and a tobacco sheet transportation conveyor belt is arranged below the first chamber 41, so as to adsorb impurities during the transportation of tobacco sheets.
[0047] Furthermore, the number of the electrostatic rollers 11 is more than one, and the electrostatic rollers 11 are arranged in parallel.
[0048] As can be seen from the above description, the parallel arrangement of multiple electrostatic rollers 11 enables the tobacco sheets to undergo multiple electrostatic separation processes when passing through, greatly improving the separation efficiency of impurities and making the impurity removal effect more significant, which is particularly suitable for tobacco sheet processing environments with more impurities. Specifically, according to the state of the incoming tobacco sheets, the central controller is used to set the charge force on each electrostatic roller 11 according to the gradient, thereby achieving graded adsorption of impurities.
