[0002] In the tobacco industry, two round rods of different specifications need to be cut and placed alternately together. After being brought together, formed, and cut, they are formed into composite round rods that meet process requirements. Currently, there are various tobacco conveying and feeding methods, but they all require complex mechanical conveying structures to accommodate the unique shapes of the materials. This setup has the disadvantages of not being able to synchronize conveying and transfer, high costs, and cumbersome operation.

[0003] The utility model patent with authorization announcement number CN219835177U discloses a system for conveying and feeding lightweight rod-shaped materials, comprising a frame on which a feed wheel and a hopper are mounted; the hopper is located above the feed wheel and does not contact the surface of the feed wheel; the feed wheel rotates to feed the material, and a plurality of sunken troughs are provided on its surface; the hopper includes at least one blanking cavity, which faces the trough below and is connected to a material conveying pipe on one side, on which a pneumatic conveying device is installed. This system for conveying and feeding lightweight rod-shaped materials uses the feed wheel to rotate to feed the material, and is designed with a self-weight hopper, an automatically straightening feed roller, and a pneumatic conveying structure above the trough. It can effectively realize the conveying and feeding functions of lightweight rod-shaped materials, and has the advantages of simple mechanical structure and low cost. However, it still does not solve the problem of synchronous transfer and delivery of rod materials. Utility Model Content

The driving mechanism drives the sprocket group to rotate and then drives the conveying chain 4 to rotate.

[0025] Several pawl assemblies are mounted on the sides of the conveyor chain 4. These pawl assemblies are used to push individual round bars within the cutting drum grooves into the round bar track. These pawl assemblies include a conveyor plate 12 and pawls 5 mounted on the conveyor plate 12. The conveyor plate 12 is connected to one side of the conveyor chain 4 via a chain pin 14, an outer chain plate, and a spring lock plate 13.

[0026] Specifically, in this embodiment, the sprocket group includes a driven sprocket 2 and a driving sprocket 11.

In order to achieve multi-stage transmission, the driving mechanism includes a gear box 1, and the gear box 1 is provided with a power gear 10 and a duplex gear 9. One side of the duplex gear 9 is connected to the power gear 10 through a toothed belt, and the other side of the duplex gear 9 is meshed with the driving gear 8 for transmission. The power gear 10 is connected to the motor. The driven sprocket 2 is mounted on the side wall of the gear box through the driven shaft 3, and the driving sprocket 11 is mounted on the side wall of the gear box through the driving shaft.

[0027] In order to ensure that the interval of each push is the same and to improve the smoothness and consistency when pushing a single round rod located in the cutting drum groove into the round rod track, the spacing values between the several pushing claws 5 are equal, and the top of the pushing claw 5 extends out of the conveying chain 4.

[0028] Example 2

[0029] This embodiment provides a chain-type pushing device after round rod slitting. The main difference from Embodiment 1 is that in this embodiment: in order to avoid shaking of the conveyor chain, a tensioning mechanism for tensioning the conveyor chain 4 is further provided on the side of the conveyor chain 4.

[0030] Specifically, the tensioning mechanism includes a tensioning sprocket 7, a tensioning sprocket shaft 15, a support arm 17, a support shaft 16, and a tension spring 6.

The other end of the tension spring 6 is fixed to the support arm 17, and the tensioning sprocket 7 is rotatably engaged with the outer side of the conveyor chain 4.

[0031] Specifically, the working process of the chain-type pushing device after round bar slitting provided by the present invention is as follows:

[0032] First, the toothed belt from the gearbox 1 drives the double gear 9 to rotate, which in turn drives the driving gear 8 to rotate, and the driving gear 8 in turn drives the driving sprocket 11 to rotate, and then drives the conveyor chain 4 to rotate on the driving sprocket 11, the driven sprocket 2, and the tensioning sprocket 7.

[0033] Specifically, the push claw assembly is mounted on a conveyor chain via a chain pin, a spring lock plate, and an outer chain plate. The conveyor chain can be a ring-shaped precision roller chain. The push claw assembly includes a conveyor plate and a push claw disposed on the conveyor plate.

[0034] The push claw on the left conveyor plate is located to the left of the center of the chain pin, while the push claw on the right conveyor plate is located to the right of the center of the chain pin. These two different conveyor plates ensure that they are installed at equal distances on the endless precision roller chain.

A support shaft is installed on one side of the gearbox, and a support arm is rotatably mounted on the support shaft. The tension sprocket shaft is rotatably mounted on the top of the support arm. A tension spring tensions the tension sprocket, which acts as tension on the endless precision roller chain.
