[0035] like Figures 1 to 4As shown, the utility model provides a cigarette box conveying and changing device, including a first conveying mechanism 1, a second conveying mechanism 2 and a changing mechanism 3. The first conveying mechanism 1 is used to convey the cigarette box 100 along the first direction. The first conveying mechanism 1 is provided with a first conveying port 11, a second conveying port 12 and a changing port 13. The first conveying port 11 and the second conveying port 12 are both used to pass the cigarette box 100. The second conveying mechanism 2 is provided at the changing port 13 and is connected to the first conveying mechanism 1, and is used to convey the cigarette box 100 along the second direction. The changing mechanism 3 is provided on one side of the first conveying mechanism 1 and includes a base 31. The telescopic assembly 32 and the lane-changing assembly 33 comprise a lane-changing member 331 and a plurality of rollers 332 spaced apart on the lane-changing member 331. The rollers 332 are rotatably connected to the lane-changing member 331 and are capable of abutting the cigarette box 100. The telescopic assembly 32 is rotatably connected to the base 31. The ends of the lane-changing member 331 are rotatably connected to the base 31. The middle portion of the lane-changing member 331 is rotatably connected to the output end of the telescopic assembly 32. The output end of the telescopic assembly 32 is used to drive the lane-changing member 331 to rotate relative to the base 31, thereby changing the movement of the cigarette box 100 from the first direction to the second direction at the lane-changing port 13. If the cigarette box 100 enters from the first conveying port 11, the telescopic assembly 32 drives the lane-changing member 331 to rotate relative to the base 31, pushing the cigarette box 100 to the lane-changing port 13 to achieve lane change. If the cigarette box 100 enters from the second conveying port 12, the telescopic assembly 32 drives the lane-changing member 331 to rotate relative to the base 31. After the lane-changing member 331 is rotated to the lane-changing port 13, the lane-changing member 331 is kept stationary, and lane-changing is achieved through the guiding effect of the lane-changing member 331. In this way, the lane of the cigarette box 100 moving from the first conveying port 11 to the second conveying port 12 can be changed, and the lane of the cigarette box 100 moving from the second conveying port 12 to the first conveying port 11 can also be changed, thereby widening the scope of application. By providing rollers 332 at intervals on the lane-changing member 331, the rollers 332 contact the cigarette box 100, thereby guiding the movement of the cigarette box 100, reducing friction between the cigarette box 100 and the lane-changing member 331, and increasing the lane-changing speed. In addition, the base 31, telescopic assembly 32, and lane-changing member 33 form a connecting rod structure, which is relatively simple in structure and highly reliable.

[0036] Optionally, in this embodiment, the base 31 includes a first mounting seat 311, a base body 314, a clamping member 312, and a first position-limiting member. The first mounting seat 311 is disposed on the base body 314; the clamping member 312 is sleeved and clamped onto the outside of the telescopic assembly 32. The outer wall of the clamping member 312 is provided with a rotating portion 3121, which is vertically rotatably connected to the first mounting seat 311. The rotating portion 3121 passes through the first mounting seat 311 and is connected to the first position-limiting member. The first position-limiting member is used to limit the position of the clamping member 312 relative to the first mounting seat 311. The provision of the clamping member 312 enables a rotational connection between the telescopic assembly 32 and the base 31, and the structure is simple and easy to install. By providing a first limiting member, the position of the clamping member 312 relative to the first mounting seat 311 is limited in the axial direction of the rotating portion 3121, thereby preventing the clamping member 312 from shaking relative to the first mounting seat 311 when the telescopic assembly 32 rotates, thereby ensuring a reliable connection between the telescopic assembly 32 and the base 31. Specifically, as Figure 4 As shown, two rotating parts 3121 are provided, and the two rotating parts 3121 are oppositely and coaxially arranged on the outer wall of the clamping member 312. The first mounting base 311 includes a support base 3111 and two support plates 3112. The two support plates 3112 are oppositely arranged on the support base 3111. The clamping member 312 is located between the two support plates 3112. The two rotating parts 3121 are respectively passed through the two support plates 3112. This arrangement ensures that the telescopic assembly 32 rotates relatively smoothly relative to the base 31. In this embodiment, the first limiting member is a retaining ring. The rotating part 3121 has an annular groove. The retaining ring is engaged in the annular groove and can be in contact with the surface of the support plate 3112.

[0037] Optionally, in this embodiment, if Figure 2 As shown, the lane-changing member 331 includes a lane-changing body 3311 and a bent plate 3312 having an L-shaped cross-section. The vertical portion of the bent plate 3312 is connected to the lane-changing body 3311, and a plurality of rollers 332 are rotatably connected to the horizontal portion of the bent plate 3312. This arrangement simplifies the structure and facilitates processing of the lane-changing member 331. Specifically, a bolt passes through the vertical portion of the bent plate 3312 and the lane-changing body 3311 and is threadedly connected to a nut, facilitating assembly and disassembly. Optionally, the base 31 includes a base body 314. The bottom of the lane-changing body 3311 is in contact with the top surface of the base body 314. When the lane-changing member 331 rotates, the bottom of the lane-changing body 3311 can slide relative to the base body 314, making the rotation of the lane-changing member 331 smoother. Specifically, the lane-changing body 3311 has an L-shaped structure, so that the lane-changing body 3311 is spaced a certain distance from the conveying surface of the first conveying mechanism 1 to avoid interference.

[0038] Optionally, the lane-changing assembly 33 further includes a first bracket 333, a first rotating shaft 334, and a second stopper 335. The base 31 includes a second mounting seat 313 and a base body 314, with the second mounting seat 313 disposed on the base body 314. The first bracket 333 is a U-shaped structure fixed to the lane-changing member 331, with the second mounting seat 313 disposed within the U-shaped structure. The first rotating shaft 334 passes through the first bracket 333 and the second mounting seat 313 and is connected to the second stopper 335. The second stopper 335 enables the first rotating shaft 334 to abut against the top surface of the first bracket 333. The second stopper 335 prevents the first bracket 333 from shaking relative to the second mounting seat 313 during rotation, thereby ensuring a secure connection between the first bracket 333 and the second mounting seat 313. Optionally, an annular groove is provided at the tail end of the first rotating shaft 334, and the second limiting member 335 is a retaining ring, which is clamped in the annular groove, and the top surface of the retaining ring can fit with the bottom surface of the first bracket 333, so that the first rotating shaft 334 abuts the top surface of the first bracket 333. Figure 3 As shown, the second mounting seat 313 includes a first mounting member 3131 and a second mounting member 3132 . The first rotating shaft 334 passes through the first bracket 333 and the first mounting member 3131 . The first mounting member 3131 is detachably connected to the second mounting member 3132 .

[0039] Optionally, the lane-changing assembly 33 further includes a dry bushing 336 and a gasket 337. The dry bushing 336 is disposed between the first rotating shaft 334 and the first bracket 333, and the gasket 337 is disposed between the dry bushing 336 and the second mounting seat 313. The dry bushing 336 reduces friction between the first bracket 333 and the first rotating shaft 334, enabling smoother rotation. The gasket 337 protects the surface of the second mounting seat 313.

[0040] Alternatively, as Figure 1As shown, the lane-changing assembly 33 also includes a second bracket 338, a second rotating shaft 339, and a third stopper. The second bracket 338 is a U-shaped structure fixed to the lane-changing member 331. A spherical bearing 321 is provided at the output end of the telescopic assembly 32, which is housed within the U-shaped structure. The second rotating shaft 339 passes through the second bracket 338 and the spherical bearing 321 and is connected to the third stopper, which allows the second rotating shaft 339 to abut against the top surface of the second bracket 338. The spherical bearing 321 at the output end of the telescopic assembly 32 allows for more flexible rotation of the lane-changing member 331 relative to the telescopic assembly 32. The third stopper prevents the second bracket 338 from shaking relative to the spherical bearing 321 during rotation, ensuring a secure connection between the second bracket 338 and the spherical bearing 321. Specifically, an annular groove is provided at the tail end of the second rotating shaft 339, and the third limiting member is a retaining ring, which is clamped in the annular groove, and the top surface of the retaining ring can fit with the bottom surface of the second bracket 338, so that the second rotating shaft 339 abuts against the top surface of the second bracket 338.

[0041] Optionally, the first conveying mechanism 1 and the second conveying mechanism 2 both include a support frame 4, a conveying assembly 5 and a guide member 6. The conveying assembly 5 is provided on the support frame 4 and is used to convey the cigarette box 100. The guide member 6 is provided on the support frame 4 and is located on both sides of the conveying assembly 5. The guide member 6 can fit the cigarette box 100. By providing the guide member 6, the cigarette box 100 is prevented from shaking left and right during transportation, and smooth transportation of the cigarette box 100 can be achieved. Furthermore, a guide avoidance portion 61 is provided on the guide member 6 near the lane change port 13, which guides the cigarette box 100 while preventing the lane change member 331 from interfering with the guide member 6 during rotation. Optionally, the conveying assembly 5 includes a motor, a transmission member and a plurality of rollers. The motor drives the plurality of rollers to rotate through the transmission member.

[0042] Alternatively, as Figure 2 As shown, the telescopic assembly 32 includes a cylinder 322 and a flow rate regulating valve 323. The cylinder 322 is rotatably connected to the base 31. The telescopic rod of the cylinder 322 is rotatably connected to the channel changer 331. Two flow rate regulating valves 323 are respectively mounted on the cylinder 322 and communicate with the two air inlets of the cylinder 322. The channel changer 331 is driven to rotate by the cylinder 322, resulting in a simple structure and easy installation and maintenance. The flow rate regulating valve 323 adjusts the gas pressure within the cylinder 322 to adjust the rotation speed of the channel changer 331, thereby adapting it to changing channels for cigarette boxes 100 with different conveying speeds. In other embodiments, the telescopic assembly 32 is an electric push rod or a hydraulic cylinder.

[0043] Optionally, both the first mounting seat 311 and the second mounting seat 313 can be detachably connected to the base body 314. To ensure secure fixation, the first mounting seat 311 and the second mounting seat 313 are fixed to the base body 314 via hexagon socket head cap bolts 315. Specifically, the hexagon socket head cap bolts 315 pass through the spring washer 316, the flat washer 317, the first mounting seat 311 (or the second mounting seat 313), and then pass through the base body 314 to be threadedly connected to the nut.

[0044] Optionally, the base body 314 can be detachably connected to the support frame 4 of the first conveying mechanism 1. Specifically, the base body 314 is provided with a plurality of waist-shaped holes 3141, and the support frame 4 is provided with a plurality of connecting holes. Bolts pass through the waist-shaped holes 3141 and the connecting holes and are threadedly connected to nuts. The waist-shaped holes 3141 facilitate adjustment of the bolt installation position according to actual conditions, preventing the bolts from being unable to be installed.

[0045] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
