The split knife in the equalizer device is a pair of circular blades, which is symmetrically arranged below the suction tape with the center line of the tobacco strand as the reference, and rotates at the same speed under the drive of the main transmission system. The equalizer trims the tobacco strand on the suction tape by using the split knife disc, and the execution component is the split knife disc and the brush wheel. The tobacco strand is trimmed by the equalizer device in the forced conveying process, the equalizer device trims the protruding part on the tobacco strand by using two split knife discs rotating in opposite directions, and is provided with a rotating brush wheel to brush off the trimmed tobacco, so as to improve the uniformity of the tobacco strand. When the split knife disc trims the tobacco, the edge below will be stained with tobacco and tobacco dust, and the function of the brush wheel is to brush off the excess tobacco trimmed by the split knife disc in time, so that the excess tobacco falls into the return silk conveying belt.

[0003] The outer contour of the brush wheel is designed as a concave type, that is, composed of four symmetrical concentric arcs with different radii. The large diameter section corresponds to the flat blade part of the split knife disc, and the small diameter section corresponds to the groove part of the split knife disc. In this way, certain requirements are put forward for the movement of the brush wheel, that is, the brush wheel should rotate by half a circle corresponding to each groove distance of the split knife disc. The brush wheel and the split knife disc are driven by the equalizer transmission box, and the synchronous rotation speed of the two can be ensured by design. The working surface is an alloy plane, and since there is a gap between the plane and the bottom of the split knife disc, the tobacco may not be brushed off or may be missed, which may cause the tobacco to be loose and even cause serious quality problems such as bamboo joint tobacco.

[0026] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a tobacco leveling device, including: two splitting discs 1 and a lowering wheel 2, the lowering wheel 2 being located below the two splitting discs 1, and there is a gap between the lowering wheel 2 and the splitting discs 1.

[0027] Specifically, the diameter of the chopping disc 1 is 112.68 mm and the circumference is 354 mm.

[0028] The lower wire wheel 2 includes a rotating block 21 and a bristle plate 22. The bristle plates 22 are evenly spaced around the rotating block 21. The first end of the bristle plate 22 is connected to the outer peripheral wall of the rotating block 21. The second end of the bristle plate 22 has a cutting edge 23, and the cross-section of the cutting edge 23 is a right-angled triangle.

The bristle plate 22 and the rotating block 21 are integrally formed, and the two acute angles of the right triangle are 60 degrees and 30 degrees.

[0030] This invention positions the feed roller 2 below two splitting discs 1, with a gap between the feed roller 2 and the splitting discs 1. This allows the brushing plates 22 to be evenly spaced around the rotating block 21. The first end of the brushing plate 22 is connected to the outer peripheral wall of the rotating block 21, and a cutting edge 23 is provided at the second end of the brushing plate 22, with the cross-section of the cutting edge 23 being a right-angled triangle. By providing the cutting edge 23 at the second end of the brushing plate 22 and making its cross-section a right-angled triangle, this invention enables the brushing plate 22 to completely remove the tobacco shreds trimmed by the splitting discs 1, ensuring smooth tobacco movement and preventing unremoved or missed tobacco shreds. This effectively solves quality defects such as hollow tobacco, bamboo-like tobacco, deviations in quality standards, and deviations in draw resistance standards.

[0031] In one embodiment of the tobacco leveling device of this utility model, the distance between the cutting edge 23 and the splitting disc 1 is less than or equal to 0.1 mm.

[0032] Specifically, to ensure good leveling effect, the lower screw wheel 2 should be as close as possible to the splitting disc 1. In order for the leveler to work normally and not interfere during movement, there should be a certain distance between the splitting disc 1 and the lower screw wheel 2. The minimum distance between the lower end face of the two splitting discs 1 and the outer contour of the lower screw wheel 2 is 0.05mm.

[0033] In one embodiment of the tobacco leveling device of this utility model, such as Figure 2 As shown, the center of the rotating block 21 is provided with a mounting hole 24, and the inner wall of the mounting hole 24 is provided with a keyway 25.

[0035] Specifically, the rotating shaft 26 is used to drive the rotating block 21 to rotate, which in turn drives the brush plate 22 connected to the rotating block to rotate, so as to remove the tobacco from the splitting disc 1. This utility model ensures the rotational stability of the rotating block 21 and the brush plate 22 by setting the mounting key on the outer wall of the rotating shaft 26, inserting the rotating shaft 26 into the mounting hole 24, and engaging with the keyway 25 through the mounting key.

[0036] In one embodiment of the tobacco leveler of this utility model, in order to improve the cleaning efficiency of the lower tobacco wheel 2, the two splitting discs 1 can rotate relative to each other, and the two splitting discs 1 are arranged in parallel, while the lower tobacco wheel 2 is arranged perpendicular to the two splitting discs 1.

[0037] In one embodiment of the tobacco leveling device of this utility model, such as Figure 1 As shown, a plurality of grooves 11 are provided on the outer peripheral wall of the splitting disc 1. The plurality of grooves 11 are evenly spaced along the outer peripheral wall of the splitting disc 1, and the bottom of the grooves 11 is lower than the bottom of the splitting disc 1.

[0038] Furthermore, the groove 11 has a depth of 3 mm and a width of 22 mm. The outer depth of the groove 11 is 3.5 mm.

[0039] This invention effectively reduces the empty end rate of cigarettes and optimizes physical indicators such as cigarette density distribution, length, draw resistance, circumference, weight, ventilation rate, tar content, nicotine content, and CO content by uniformly arranging multiple grooves 11 along the outer peripheral wall of the splitting disc 1, with the bottom of the grooves 11 lower than the bottom of the splitting disc 1, and setting the depth of the grooves 11 to 3mm and the width of the grooves 11 to 22mm.

[0040] In one embodiment of the tobacco leveling device of this utility model, such as Figure 1 and Figure 2 As shown, the center of the splitting disc 1 has a connecting hole, and the tobacco leveler also includes a leveler drive shaft 4 and a fastening bolt 3. The leveler drive shaft 4 is provided with a threaded hole, and the leveler drive shaft 4 abuts against the center of the splitting disc 1. The fastening bolt 3 passes through the connecting hole and connects with the threaded hole.

[0041] This utility model improves the stability of the installation of the splitter disc 1 by abutting the center position of the leveling device drive shaft 4 and the splitter disc 1, and connecting the fastening bolt 3 through the connecting hole and the threaded hole. It also enables the leveling device drive shaft 4 to stably drive the splitter disc 1 to rotate.

[0042] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
