DETAILED DESCRIPTION

[0019] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0020] See also Figure 1 and Figure 2 , a tobacco conveyor belt correction device according to a specific embodiment of the present invention includes a conveyor belt mounting bracket 1, a conveyor belt driven roller 2, a drive motor 3, a second bracket 4, a correction sliding rail 5, and a transmission mechanism 6. A notch is provided on the conveyor belt mounting bracket 1, and a group of correction sliding rails 5 are respectively installed at the upper and lower edges of the notch. The upper and lower ends of the second bracket 4 are respectively slidably connected with a group of correction sliding rails 5. One end of the conveyor belt driven roller 2 is installed on the conveyor belt mounting bracket 1, and the other end is installed on a second bracket 4. The drive motor 3 is fixedly installed on the conveyor belt mounting bracket 1, and the output shaft of the drive motor 3 is transmission-connected to the second bracket 4 through the transmission mechanism 6. The drive motor 3 can drive the second bracket 4 to move on the correction sliding rail 5 through the transmission mechanism 6, thereby driving the conveyor belt driven roller 2 with its end mounted on the conveyor belt mounting bracket 1 as the center to adaptively swing, and the technician adjusts the position of the conveyor belt wrapped around the conveyor belt driven roller 2 by adjusting the swing amplitude of the conveyor belt driven roller 2 to achieve the deviation correction operation of the conveyor belt.

[0021] Specifically, see Figure 2 The transmission mechanism 6 includes a driving gear 61 and a driven rack 62. The driving gear 61 is fixedly mounted on the output shaft of the driving motor 3. The driven rack 62 is horizontally fixedly mounted on the second bracket 4, and the driven rack 62 is meshed with the driving gear 61. The driving motor 3 can drive the driven rack 62 to move linearly through the driving gear 61, thereby driving the second bracket 4 to move on the correction sliding track 5.

[0022] In this embodiment, the deviation-correcting sliding rails 5 are multiple pairs of clamping plates equidistantly arranged along the conveying direction of the conveyor belt, and a gap is left between each pair of clamping plates for the corresponding upper end or lower end of the second bracket 4 to slide through.

[0023] In this embodiment, a rack limit seat 72 is also fixedly provided on the conveyor belt mounting bracket 1, and a slide groove is provided at the lower end surface of the rack limit seat 72, which is adapted to the driven rack 62. The extension direction of the slide groove corresponds to the conveying direction of the conveyor belt. The driven rack 62 is moved in a straight line by the driving gear 61 and is also limited by the rack limit seat 72 to improve the structural stability of the transmission mechanism 6.

[0024] In this embodiment, to enable the conveyor belt driven roller 2 to rotate about its own axis and swing appropriately about one end, the conveyor belt driven roller 2 is mounted on the second bracket 4 via a corresponding self-aligning bearing. Specifically, the self-aligning bearing is sleeved and mounted on the corresponding end of the conveyor belt driven roller 2. A bearing seat is correspondingly mounted on the second bracket 4, and the outer ring of the self-aligning bearing is fixedly mounted on the bearing seat.

[0025] In this embodiment, a technician can visually observe whether the conveyor belt is deviating, and manually operate the control switch of the drive motor 3 to control the swing amplitude of the conveyor belt driven roller 2, thereby manually adjusting the deviated conveyor belt back to its original position. In other embodiments, a technician can also install a detection component 8 on the conveyor belt mounting bracket 1. The detection component 8 can be an instrument component such as a photoelectric detection sensor, a visual camera, etc. The technician can then connect the control switch of the drive motor 3 to a computer, and the computer can automatically control the operating state of the drive motor 3 based on the deviation detection data of the detection component 8, thereby further realizing automated deviation correction operation.

[0026] It should be noted that: in other embodiments, correction devices can be installed at both ends of the conveyor belt driven roller 2, and technicians can control the two second brackets 4 of the two correction devices to produce a moving stroke difference, thereby causing the conveyor belt driven roller 2 to swing along the tobacco conveying direction on the conveyor belt to correct the deviated conveyor belt back to its original position.

[0027] In addition, to prevent the second bracket 4 from sliding out of the correcting sliding track 5, limit switches 9 are provided at the two ends of the correcting sliding track 5 on the conveyor belt mounting bracket 1, and limit baffles 91 are provided at the corresponding positions at the two ends of the second bracket 4. The limit switch 9 is a contact switch. In this regard, when the second bracket 4 slides back and forth along the conveying direction of the conveyor belt under the drive motor 3, each time the limit baffle 91 on the second bracket 4 contacts the limit switch 9, the limit switch 9 will be triggered. The limit switch 9 is connected to the controller of the drive motor 3. Therefore, each time the limit switch 9 is triggered, a corresponding electrical signal will be transmitted to the controller of the drive motor 3. After receiving the triggering electrical signal from the limit switch 9, the controller of the drive motor 3 will immediately control the drive motor 3 to stop, thereby effectively preventing the second bracket 4 from moving over the travel.

[0028] Any matters not mentioned above are applicable to the prior art.

[0029] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
