[0040] The following reference Figures 1 to 5 This invention introduces the brush roller and tobacco conveying equipment provided by this utility model.

[0041] This embodiment provides a brush roller that enables quick disassembly and assembly, improving maintenance and replacement efficiency.

[0042] Please refer to Figure 1 and Figure 2Specifically, the brush roller includes a brush shaft 20, a brush cylinder 30, two shaft heads 10, and two locking assemblies; both shaft heads 10 are mounted on a tobacco conveying device; the brush shaft 20 is disposed between the two shaft heads 10, and both ends of the brush shaft 20 are detachably connected to the two shaft heads 10 respectively; the brush cylinder 30 is sleeved on the outer periphery of the brush shaft 20; the two locking assemblies are respectively disposed at both ends of the brush shaft 20, and the brush cylinder 30 is clamped between the two locking assemblies, the locking assemblies being used to lock and fix any end of the brush shaft 20 to the corresponding shaft head 10.

[0043] In this embodiment, the brush roller divides the shaft system used to support and connect the tobacco conveying equipment into a brush shaft 20 and two shaft heads 10. The two shaft heads 10 are connected to the tobacco conveying equipment. The brush shaft 20 is fitted with a brush cylinder 30 and locked and fixed to the two shaft heads 10 respectively by a locking assembly, thereby realizing the installation of the brush roller. When maintenance and disassembly are required, the locking assembly can be removed to separate the shaft heads 10 and the brush shaft 20, thereby realizing the disassembly of the brush roller. This achieves quick disassembly and assembly of the brush roller and improves maintenance and replacement efficiency.

[0044] Specifically, the shaft head 10 is connected to the tobacco conveying equipment via a bearing housing to achieve the connection between the brush roller and the tobacco conveying equipment.

The brush shaft 20 is fixed to the locking ring 41 by the first fastening bolt, and the shaft head 10 is fixed to the locking ring 41 by the second fastening bolt, thereby achieving the locking function of the locking assembly to lock and fix the brush shaft 20 and the shaft head 10.

[0046] Specifically, the locking assembly also includes a locking bolt. One of the two locking half-circles 411 has a first through hole 412 and the other has a first threaded blind hole 413. One end of the locking bolt passes through the first through hole 412 and is threadedly connected to the first threaded blind hole 413, which enables the locking ring 41 to be detachable, thereby facilitating the disassembly and assembly of the brush roller.

[0047] Optionally, the first through hole 412 is a countersunk hole, which facilitates the installation of the locking bolt and avoids interference caused by the locking bolt protruding too much.

[0048] Furthermore, at least two sets of locking bolts, first through holes 412, and first threaded blind holes 413 are provided in a one-to-one correspondence to improve the connection stability between the two locking half-turns 411.

[0049] Specifically, one of the two locking half-rings 411 has two second through holes 414 arranged in sequence along the axial direction, and the other has two second threaded blind holes 415 arranged in sequence along the axial direction. The two second through holes 414 and the two second threaded blind holes 415 are arranged in a one-to-one correspondence. One end of the first fastening bolt passes through the second through hole 414 near the brush cylinder 30 and the brush shaft 20 and is threadedly connected to the corresponding second threaded blind hole 415, thereby fixing the brush shaft 20 to the locking ring 41. One end of the second fastening bolt passes through the other second through hole 414 and the brush shaft 20 and is threadedly connected to the corresponding second threaded blind hole 415, thereby fixing the shaft head 10 to the locking ring 41.

[0050] Optionally, the outer circumferential surface of the locking half-ring 411 with the second through hole 414 is provided with a beveled portion 418 so that the mounting surfaces of the first fastening bolt and the second fastening bolt are flat, which facilitates their tightening and fixing.

[0051] Please refer to Figure 2 In order to fix the brush shaft 20, optionally, a first radial through hole 21 is provided on the outer peripheral surface of the brush shaft 20, and one end of the first fastening bolt passes through the second through hole 414 and the first radial through hole 21 near the brush cylinder 30 and is threadedly connected to the corresponding second threaded blind hole 415, so that the first fastening bolt can lock and fix the brush shaft 20 to the locking ring 41.

[0052] Please refer to Figure 5 In order to fix the shaft head 10, optionally, a second radial through hole 11 is provided on the outer peripheral surface of the shaft head 10, and one end of the second fastening bolt passes through another second through hole 414 and the second radial through hole 11 and is threadedly connected to the corresponding second threaded blind hole 415, so that the second fastening bolt can lock and fix the shaft head 10 to the locking ring 41.

[0053] Please refer to Figure 2 and Figure 5 Optionally, one of the ends of the brush shaft 20 and the end of the shaft head 10 is provided with a protrusion 22 and the other with a groove 12. The protrusion 22 is inserted into the groove 12, which realizes the positioning of the two, thereby avoiding relative rotation between the two along their own circumference and improving the reliability of the brush roller.

[0054] Furthermore, the brush cylinder 30 can be either one-piece or two-piece, with brushes on its outer surface to achieve the cleaning effect on tobacco.

[0055] Please return to the reference. Figure 1and Figure 2 For example, the brush cylinder 30 in this embodiment adopts a split structure. Specifically, the brush cylinder 30 includes several brush sub-cylinders 31. One of the two ends of the brush sub-cylinder 31 along its own axial direction is provided with a first pin 311 and the other is provided with a first pin hole 312. The first pin 311 of one brush sub-cylinder 31 is inserted into the first pin hole 312 of another brush sub-cylinder 31, realizing the positioning and installation between the various brush sub-cylinders 31, thereby realizing the assembly and forming of the brush cylinder 30.

[0056] Furthermore, the locking assembly has a second pin 416 at one end along its own axial direction and a second pin hole 417 at the other end. The second pin 416 can be engaged with the first pin hole 312 of the brush cylinder 30, and the second pin hole 417 can be engaged with the first pin 311 of the brush cylinder 30. This improves the connection between the locking ring 41 and the brush cylinder 30, realizes the positioning and installation between the two, and avoids problems such as end face wear caused by relative rotation between the two.

[0057] Optionally, at least two of each of the first pin 311, the first pin hole 312, the second pin 416, and the second pin hole 417 are provided to improve the limiting effect between the brush cylinders 31 and the limiting effect between the brush cylinder 30 and the locking ring 41.

[0058] This embodiment also provides a tobacco conveying device, which includes the brush roller described in any of the above embodiments. By using this brush roller, not only can the tobacco be cleaned, but it is also easy to disassemble and maintain, thus improving maintenance and replacement efficiency.

[0059] Specifically, the brush roller is installed at the discharge end of the tobacco conveying equipment, and the two shaft heads 10 are fixedly connected to the frame at the discharge end by two bearing seats to achieve the installation and fixation of the brush roller.
