Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically to an automatic tobacco pipe leveling mechanism. Background Technology

[0002] In the tobacco processing industry, the neat arrangement and orderly feeding of tobacco canisters are crucial to ensuring the smooth operation of subsequent production processes. Traditionally, the leveling and feeding of tobacco canisters have relied heavily on manual operation or simple mechanical assistance. This method is not only inefficient but also makes it difficult to guarantee the stability and consistency of the tobacco canisters during the feeding process.

[0003] Specifically, when a large number of chimneys are fed into the hopper, due to gravity and collisions between them, the chimneys often become scattered and disordered, resulting in overlapping, crossing, or even blockages. This scattered arrangement of chimneys not only increases the difficulty of subsequent processing but may also cause surface scratches or deformation due to irregular contact between the chimneys, affecting the appearance quality of the product. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic chimney leveling mechanism, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic chimney leveling mechanism, comprising a chimney feeding bin, a leveling drive module mounted on the back of the chimney feeding bin, and a plurality of first rollers and a plurality of second rollers rotatably connected inside the chimney feeding bin. The leveling drive module has a plurality of drive ends, each drive end being connected to a corresponding first roller and a second roller, and the leveling drive module is capable of driving the plurality of first rollers and the plurality of second rollers to rotate synchronously.

[0006] Furthermore, the chimney feeding bin includes a bin shell and a bin cover, which are fixedly connected by several bolts. The top of the chimney feeding bin is provided with a feeding port, and the bottom is provided with a discharging port.

[0007] Furthermore, the bottom of the hopper shell is provided with a number of first reserved holes and a number of second reserved holes. The first reserved holes are located above the second reserved holes. The first roller shaft and the second roller shaft are rotatably connected to the inside of the first reserved holes and the second reserved holes through bearings.

[0008] Furthermore, a buffer guide is symmetrically installed in the middle of the hopper shell, and the buffer guide has a rhomboid structure.

[0009] Furthermore, the first roller and the second roller are distributed at equal distances in the transverse direction. The diameter of the first roller is larger than the diameter of the second roller, and the number of the first rollers is less than the number of the second rollers. Both the first roller and the second roller are regular hexagonal structures.

[0010] Furthermore, the leveling drive module includes a lower slide rail, an upper slide rail, and a cylinder installed on the back of the chimney feed hopper. The cylinder is located between the lower slide rail and the upper slide rail. The lower slide rail and the upper slide rail are slidably connected to each other. The two ends of the lower slide rail and the upper slide rail are connected and fixed by a linkage rod. The telescopic end of the cylinder is connected and fixed to one of the linkage rods.

[0011] Furthermore, each first roller shaft and each second roller shaft is equipped with a first gear and a second gear at their respective ends, and the first gear and the second gear mesh with the upper rack and the lower rack respectively.

[0012] This utility model provides an automatic chimney leveling mechanism. Compared with the prior art, it has the following advantages:

[0013] This automatic chimney leveling mechanism, by incorporating two layers of hexagonal rollers within the chimney feeding hopper, with each roller driven synchronously by a leveling drive module, achieves automatic leveling and orderly arrangement of chimneys during the feeding process. This significantly improves the stability and consistency of chimney feeding, effectively preventing overlap, crossing, and blockage between chimneys, thus ensuring the smooth progress of subsequent processing steps. Furthermore, the hexagonal roller design increases the contact area with the chimney, enhancing the leveling effect and resulting in more neat and aesthetically pleasing chimneys exiting the feeding hopper, meeting the high standards required in the production process.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-8 This utility model provides a technical solution: an automatic chimney leveling mechanism, comprising a chimney feeding bin 1, a leveling drive module 2, several first rollers 3, and several second rollers 4. The chimney feeding bin 1 consists of a bin shell 11 and a bin cover 12, which are fixedly connected by several bolts. The top of the chimney feeding bin 1 has an inlet, and the bottom has an outlet. The leveling drive module 2 is installed on the back of the chimney feeding bin 1. The bottom of the bin shell 11 has several first pre-drilled holes 111 and several second pre-drilled holes 112, with the first pre-drilled holes 111 located above the second pre-drilled holes 112. The first rollers 3 and second rollers 4 are rotatably connected to each other via bearings. Inside the first reserved hole 111 and the second reserved hole 112, in addition, a buffer guide 113 is symmetrically installed in the middle of the casing 11. The buffer guide 113 has a rhomboid structure. The rhomboid structure can reduce the downward movement speed of the chimney, thereby preventing the chimney from being blocked. The leveling drive module 2 has several drive ends. Each drive end is connected to the first roller shaft 3 and the second roller shaft 4 respectively. Thus, the leveling drive module 2 can drive several first roller shafts 3 and several second roller shafts 4 to rotate synchronously. The first roller shafts 3 and the second roller shafts 4 are distributed horizontally at equal distances. The diameter of the first roller shaft 3 is larger than the diameter of the second roller shaft 4, and the number of first roller shafts 3 is less than the number of second roller shafts 4. Both the first roller shaft 3 and the second roller shaft 4 have a regular hexagonal structure.

[0025] The leveling drive module 2 includes a lower slide rail 21, an upper slide rail 22, and a cylinder 23 installed on the back of the chimney feeding hopper 1. The cylinder 23 is located between the lower slide rail 21 and the upper slide rail 22. The lower slide rail 21 and the upper slide rail 22 are slidably connected to the interior of the lower slide rail 21 and the upper slide rail 22, respectively. The two ends of the lower slide rail 21 and the upper slide rail 22 are connected and fixed by a linkage rod 28. The telescopic end of the cylinder 23 is connected and fixed to one of the linkage rods 28. The ends of each first roller shaft 3 and each second roller shaft 4 are respectively equipped with a first gear 26 and a second gear 27, respectively. The first gear 26 and the second gear 27 mesh with the upper rack 24 and the lower rack 25, respectively.

[0026] The automatic chimney leveling mechanism works by placing the chimney into the chimney feeding bin 1 and then activating cylinder 23, which continuously extends and retracts. Taking the extension action as an example, the extension end of cylinder 23 pushes the linkage rod 28 to the right, thereby causing the upper rack 24 and lower rack 25 to slide to the right inside the lower slide rail 21 and upper slide rail 22, respectively. Due to the meshing of the gears, when the upper rack 24 and lower rack 25 move to the right synchronously, each first gear 26 and second gear 27 will rotate synchronously, which will drive each first roller shaft 3 and each second roller shaft 4 to rotate synchronously. During the rotation, the originally scattered chimneys become flat, thus ensuring that the chimneys discharged from the chimney feeding bin 1 are neat and beautiful, which is conducive to subsequent processing operations.
