In the absence of conflict, the embodiments of the present application and the technical features in the embodiments may be combined with each other.

[0022] Embodiment 1:

[0023] This embodiment provides a tobacco lifting and reciprocating conveying device, such as Figure 1-2 As shown, it includes: a support frame 1, a feeding hopper 2 and a transmission belt 6. The support frame 1 is vertically arranged on the ground. The transmission belt 6 is vertically sleeved on the support frame 1 along the length direction of the support frame 1. The feeding hopper 2 is detachably connected to the transmission belt 6 by bolts. A driving mechanism is arranged on the support frame 1. The driving mechanism is transmission-connected with the transmission belt 6. A tensioning mechanism for tensioning the transmission belt 6 is arranged on the support frame 1. The transmission belt 6 is driven to slide on the support frame 1 by the driving mechanism, thereby driving the feeding hopper 2 to reciprocate on the support frame 1 to transport the tobacco in the feeding hopper 2. By arranging the tensioning mechanism on the support frame 1, the tobacco shreds sleeved on the support frame 1 can be transported. The transmission belt 6 on the support frame 1 is tensioned to prevent the transmission belt 6 from slipping due to slackness. The tensioning mechanism includes a tensioning wheel 8 and two pressure wheels 7. The tensioning wheel 8 is arranged between the two pressure wheels 7. The pressure wheel 7 is arranged on the outside of the transmission belt 6 and is connected to the transmission belt 6 by transmission. The tensioning wheel 8 is arranged on the inside of the transmission belt 6 and is connected to the transmission belt 6 by transmission. By inserting the transmission belt 6 between the pressure wheel 7 and the tensioning wheel 8, the tensioning force on the transmission belt 6 is increased. By arranging the pressure wheels 7 on both sides of the tensioning wheel 8, the transmission belt 6 is ensured to be close to the support frame 1, and the transmission belt 6 is ensured to be vertical, thereby improving the stability of the operation of the feeding hopper 2.

[0024] In this embodiment, Figure 3 As shown, the tensioning mechanism is also provided with an adjusting component, which includes an adjusting block 11 and a connecting block 10. The adjusting block 11 is rotatably connected to the support frame 1, one end of the adjusting block 11 is fixedly connected to the connecting block 10, and the tensioning wheel 8 is arranged on the connecting block 10. By arranging the adjusting component on the tensioning mechanism, rotating the adjusting block 11 drives the tensioning wheel 8 to rotate, thereby changing the position of the wheel, tensioning the transmission belt 6, and preventing the transmission belt 6 from slipping. In this embodiment, four adjusting holes 9 are circumferentially opened on the adjusting block 11, and positioning holes matching the adjusting holes 9 are opened on the support frame 1. A positioning bolt is detachably arranged in the positioning hole. By inserting the positioning bolt through the adjusting hole 9 circumferentially opened on the adjusting block 11 and into the positioning hole, the rotated adjusting block 11 can be fixed, so that the tensioning wheel 8 can stably tension the transmission belt 6 and prevent the transmission belt 6 from slipping.

[0025] In this embodiment, Figure 1 , Figure 3 As shown, a top transmission wheel 4 and a bottom transmission wheel 5 are respectively provided at both ends of the support frame 1, and the top transmission wheel 4 and the bottom transmission wheel 5 are both rotatably connected to the support frame 1, and a transmission belt 6 is sleeved on the top transmission wheel 4 and the bottom transmission wheel 5. A travel switch can also be provided at the top transmission wheel 4 and the bottom transmission wheel 5. When the feeding hopper 2 is about to reach the top transmission wheel 4 and the bottom transmission wheel 5, the motor 3 stops running, and a plurality of middle transmission wheels are provided between the top transmission wheel 4 and the bottom transmission wheel 5. The plurality of middle transmission wheels are rotatably connected inside the support frame 1, and the transmission belt 6 is transmission-connected with the middle transmission wheel. By providing the top transmission wheel 4 and the bottom transmission wheel 5 at both ends of the support frame 1, the friction force of the transmission belt 6 moving on the support frame 1 is reduced, and by providing a plurality of middle transmission wheels, a supporting role is played on the transmission belt 6 located between the top transmission wheel 4 and the bottom transmission wheel 5, thereby improving the overall stability.

[0026] In this embodiment, Figure 2 As shown, the driving mechanism includes a motor 3, which is arranged on the support frame 1. The output end of the motor 3 is fixedly connected to the bottom transmission wheel 5. The motor 3 drives the bottom rotating wheel to rotate, thereby driving the transmission belt 6 to run, and the operation of the transmission belt 6 is controlled more accurately.

[0027] Embodiment 2:

[0028] This embodiment provides a tobacco lifting and reciprocating conveying device, such as Figure 1-2As shown, different from Example 1, in this embodiment, two transmission belts 6 are provided, and correspondingly, two driving mechanisms, tensioning mechanisms and adjusting components are each provided, and the two transmission belts 6 are arranged on the support frame 1 in parallel, and each transmission belt 6 is equipped with a driving mechanism, a tensioning mechanism and an adjusting component. The tobacco lifting and reciprocating conveying device provided in this embodiment can convey tobacco to any target height, making the transmission of tobacco more convenient, thereby improving the efficiency of tobacco transmission. By providing two transmission belts 6, when one transmission belt 6 fails, the feed hopper 2 is connected through the other transmission belt 6 to continue working, thereby ensuring the safety and stability of the operation of the device.

[0029] When using the device, the feed hopper 2 is connected to a transmission belt 6 by bolts. When the tobacco in the feed hopper 2 needs to be transmitted, the motor 3 is started and the output end of the motor 3 is controlled to rotate in one direction. The output end of the motor 3 drives the bottom transmission wheel 5 fixed thereto to rotate, thereby driving the transmission belt 6 sleeved on the bottom transmission wheel 5 to move. The transmission belt 6 is inserted between the clamping wheel 7 and the tensioning wheel 8. The transmission belt 6 is tensioned under the joint action of the clamping wheel 7 and the tensioning wheel 8, so that the feed hopper 2 is smoothly transported to the target position. The output end of the motor 3 is controlled to rotate in the reverse direction to drive the transmission belt 6 to move in the reverse direction, thereby transporting the feed hopper 2 in the opposite direction. In order to prevent the transmission belt 6 from slipping, the adjustment block 11 can be rotated. The adjustment block 11 1 drives the connecting block 10 fixed thereto to rotate, thereby driving the tensioning wheel 8 arranged at the other end of the connecting block 10 to rotate around the adjusting block 11. During the rotation of the tensioning wheel 8, the length of the transmission belt 6 between the two pressing wheels 7 changes, and the tensioning force on the transmission belt 6 is adjusted. When the tensioning force on the transmission belt 6 is appropriate, the positioning bolt is passed through the adjustment hole 9 corresponding to the positioning hole and inserted into the positioning hole to limit the rotation of the adjusting block 11 and ensure constant tensioning force. When the transmission belt 6 connected to the feeding hopper 2 or the components cooperating with the transmission belt 6 fail and cannot operate normally, the feeding hopper 2 is removed from the transmission belt 6, and the feeding hopper 2 is connected to another transmission belt 6 to continue the operation of transporting tobacco.

[0030] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
