[0021] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other.

[0022] Please refer to Figures 1 to 6 . A two-way roller conveyor includes a roller group, a steering mechanism 20 and a base 30. The roller group includes a first component 11 and a second component 12. The first component 11 and the second component 12 can independently transport materials respectively. The first component 11 and the second component 12 are connected, and an included angle is formed between the first component 11 and the second component 12. The roller group is rotatably arranged on the base 30. The base 30 is used to support the rolling group. The steering mechanism 20 is connected to the roller group to drive the roller group to rotate. Under the drive of the steering mechanism 20, the roller group can rotate to make the first component 11 support on the base 30, or the second component 12 support on the base 30; when the first component 11 supports on the base 30, the first component 11 transports materials in the first direction, and when the second component 12 supports on the base 30, the second component 12 transports materials in the second direction; the material transportation direction can be changed by rotating the roller group, so as to transport cigarettes of different specifications to different processing links and realize material sorting.

[0023] The roller group includes a first component 11 and a second component 12. The first component 11 includes a first frame 111 and a first roller 112. The first frame 111 is a rectangular frame body. The two ends of the first roller 112 are rotatably arranged on both sides of the first frame 111. A number of first rollers 112 are arranged at intervals along the length direction of the first frame 111, and the rotation axes of the first rollers 112 are located in the same plane, so that the material can be smoothly transported on the first rollers 112.

[0024] The second component 12 includes a second frame 121 and a second roller 122. The second frame 121 is a rectangular frame body. The two ends of the second roller 122 are rotatably arranged on both sides of the second frame 121. A number of second rollers 122 are arranged at intervals along the length direction of the second frame 121, and the rotation axes of the second rollers 122 are located in the same plane, so that the material can be smoothly transported on the second rollers 122.

[0025] The end of the first component 11 is connected to the end of the second component 12, and there is an included angle between the first component 11 and the second component 12. The included angle should be greater than or equal to 90° and less than 180°. Taking the first component 11 transporting materials as an example, when the first component 11 transports materials, the second component 12 is located beside the first component 11, and there is no obstruction above the first component 11, which does not affect the material transportation.

[0026] Specifically, the end of the first frame 111 is connected to the end of the second frame 121, and the included angle between the first frame 111 and the second frame 121 is a right angle. The base 30 includes a support frame 31 and feet. A number of feet are arranged at the bottom of the support frame 31 to support the support frame 31. The support frame 31 is a rectangular frame, horizontally placed on the feet. The top surface of the support frame 31 is a plane. The roller group is rotatably arranged on the support frame 31, and the roller group rotates relative to the base 30, so that the first frame 111 or the second frame 121 is placed on the top surface of the support frame 31. When it rotates to the first frame 111 contacting the support frame 31, the first component 11 transports materials, and the materials move on the first rollers 112 in the first direction; when it rotates to the second frame 121 contacting the support frame 31, the second component 12 transports materials, and the materials move on the second rollers 122 in the second direction.

[0027] A rotating shaft 13 is fixedly arranged at the connection of the first frame 111 and the second frame 121. Support seats 311 are arranged on both sides of the support frame 31. The rotating shaft 13 is arranged perpendicular to the side of the support frame 31. The two ends of the rotating shaft 13 are rotatably arranged in the support seats 311. The rotating shaft 13 rotates relative to the support seats 311, thereby driving the roller group to rotate relative to the base 30.

[0028] In this embodiment, the first direction and the second direction are two opposite directions. Since the included angle between the first component 11 and the second component 12 is a right angle, the top surface of the support frame 31 is a plane, and the rotating shaft is perpendicular to the side of the support frame 31. By rotating the roller group 90° forward and backward, the transportation direction of the roller group can be switched to enable transportation by the first component 11 or the second component 12.

[0029] Specifically, rotate the rotating shaft 13 so that the first frame 111 is placed on the support frame 31, and materials can be transported in the first direction through the first roller 112; if materials are to be transported in the second direction, drive the rotating shaft 13 to rotate reversely by 90°, so that the second frame 121 is placed on the support frame 31, and materials can be transported in the second direction through the second roller 122.

[0030] Furthermore, a first buffer block 321 and a second buffer block 322 are provided on the support frame 31. The first buffer block 321 and the second buffer block 322 are respectively arranged at both ends of the support frame 31 to buffer the rotating first frame 111 and second frame 121 respectively, and avoid rigid collision between the first frame 111, the second frame 121 and the support frame 31. In this embodiment, the first buffer block 321 and the second buffer block 322 have the same structure and are both rubber blocks. The two first buffer blocks 321 are arranged on the same side of the support frame 31 and are fixedly arranged on the top surface of the support frame 31. When the roller group rotates and the first component 11 falls onto the support frame 31, the first frame 111 contacts the buffer block, and the two first buffer blocks 321 support the first component 11 on both sides of the first frame 111. Similarly, the two second buffer blocks 322 are arranged on the same side of the support frame 31 and are fixed to the top surface of the support frame 31. When the roller group rotates and the second component 12 falls under the support frame 31, the second frame 121 contacts the buffer block, and the two second buffer blocks 322 support the second component 12 on both sides of the second frame 121.

[0031] A first elastic rod 331 and a second elastic rod 332 are further provided on the support frame 31 to respectively slow down the falling speeds of the first component 11 and the second component 12, and further reduce the impact generated when the first frame 111 collides with the support frame 31 and the second frame 121 collides with the support frame 31. The first elastic rod 331 and the first buffer block 321 are arranged on the same side, and the second elastic rod 332 and the second buffer block 322 are arranged on the same side. In this embodiment, the first elastic rod 331 and the second elastic rod 332 have the same structure. Taking the first elastic rod 331 as an example, it includes a straight rod and a spring. A rubber pad is fixedly arranged at the end of the straight rod. An installation hole is provided on the support frame 31, and the installation hole penetrates through the thickness direction of the support frame 31. The straight rod is inserted into the installation hole and is arranged perpendicular to the top surface of the support frame, and the end with the rubber pad faces upward; the spring is sleeved outside the support rod and is arranged in the installation hole. One end of the spring is fixedly connected to the inner wall of the installation hole, and the other end of the spring is fixedly connected to the outer wall of the straight rod. And in the initial state, the rubber pad is higher than the first rubber block, so that when the first frame 111 falls, it first contacts the first elastic rod 331. Specifically, the roller group rotates, the first component 11 falls, and the first frame 111 first contacts the first elastic rod 331. The spring is compressed by the force. Under the action of the spring, the falling speed of the first frame 111 decreases until it contacts the first buffer block 321. When the moving speed of the first frame 111 is zero, the first frame 111 is stable on the first elastic rod 331 and the first buffer block 321. The first elastic rod 331 and the first buffer block 321 jointly provide support for the first frame 111. At this time, the material moves in the first direction through the first component 11.

[0032] In this embodiment, the steering mechanism 20 is a telescopic cylinder. The steering mechanism 20 is arranged below the roller group. Its fixed end is rotatably connected to the base 30, and its piston end is rotatably connected to the first component 11 or the second component 12. By the telescoping of the cylinder, the roller group is driven to rotate around the rotating shaft 13, changing the orientation of the roller group, and further changing the material transportation direction. In this embodiment, the steering mechanism 20 is connected to the second component 12, and the roller group is driven to rotate around the rotating shaft 13 by driving the second component 12.

[0033] As another implementation manner, the steering mechanism 20 can be a forward and reverse motor. The output shaft of the motor is directly connected to the rotating shaft 13. By rotating the rotating shaft 13, the orientation of the roller group is changed, and further the material transportation direction is changed.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
