Description

Technical Field

[0001] This utility model relates to the field of tobacco technology, specifically to a tobacco vibrating screening device. Background Technology

[0002] Tobacco shreds refer to tobacco products made by cutting tobacco leaves into shreds, granules, flakes, powder, or other shapes, adding auxiliary materials, fermenting and storing them, and then selling them for smoking without rolling them. Examples include pipe tobacco, mozzarella tobacco, tobacco dust, hookah, and yellow and red tobacco shreds. There are various ways to use tobacco shreds. They can be rolled into any shape with cigarette paper, rolled into cigarette shape using a special cigarette rolling machine, or used in conjunction with smoking devices such as pipes.

[0003] Currently, when using tobacco shredding vibrating screening devices, perforated screens are typically used in conjunction with vibrating motors to screen the crushed waste cigarettes, thereby improving the purity of the tobacco shredding. However, in actual use, once a large amount of material accumulates on the screen, the upper layer of tobacco shredding is pressed firmly onto the lower layer. Even with screen vibration, it is difficult to fully disperse the bottom layer of tobacco shredding, which easily clogs the screen holes and greatly affects the screening efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a vibrating screening device for tobacco shreds. By setting a mounting bracket, a connecting shaft, and multiple sets of material-pushing plates on the screening frame, and with the cooperation of a rotating component, the connecting shaft can drive the multiple sets of material-pushing plates to rotate, thereby causing the material-pushing plates to lift the material on the screening screen. Furthermore, by setting a movable block and a moving component, the mounting bracket can drive the connecting shaft to move back and forth within the screening frame. Under the combined effect of this structure, the upper and lower layers of material can be effectively separated and dispersed, which is conducive to the flow of tobacco shreds and greatly improves the vibration screening efficiency of tobacco shreds, thus solving the above-mentioned shortcomings in the technology.

[0024] This utility model provides, for example Figures 1-3 The illustrated tobacco shredding vibrating sieving device includes:

[0025] Screening frame 1, with support legs 3 fixed at all four ends of the bottom of the screening frame 1, and a screening screen 2 is installed inside the screening frame 1. A vibration component is provided on one side of the screening frame 1, and a guide frame 6 is provided between the four support legs 3 near the bottom of the screening screen 2.

[0026] The vibration assembly includes a vibration motor 4 fixedly connected to the side wall of the screening frame 1 via a bracket. The output end of the vibration motor 4 is connected to a connecting handle 5, and the connecting handle 5 is connected to the screening screen 2.

[0027] A collection frame 7 is provided on the inner side of the support leg 3 and below the opening end of the guide frame 6. Handles are symmetrically fixed on both sides of the collection frame 7. The collection frame 7 can be easily moved by using the handles.

[0028] In use, tobacco shreds can be put into the screening frame 1. By starting the vibration motor 4, the vibration motor 4 can drive the screening screen 2 to vibrate through the connecting handle 5, so that the screening screen 2 can vibrate and screen the tobacco shreds. Fine tobacco shreds can fall through the screen holes onto the guide frame 6 and then flow into the collection frame 7, thus realizing screening processing and greatly improving the purity of tobacco shreds.

[0029] The bottom end of the outrigger 3 is fixed with a mounting plate, and the mounting plate is provided with mounting holes.

[0030] The top two sides of the screening frame 1 are symmetrically provided with movable card seats 11. The two card seats 11 are rotatably connected to the upper part of the screening screen 2 via a bearing. The outer wall of the connecting shaft 14 is provided with multiple sets of material feeding plates 15 arranged in a ring array, and one end of the connecting shaft 14 is provided with a rotating component.

[0031] The rotating assembly includes a second motor 19 fixed to the top of one of the card holders 11. The output end of the second motor 19 is connected to a second synchronous pulley 17. A first synchronous pulley 16 is fixed to one end of the connecting shaft 14 near the second synchronous pulley 17. A synchronous belt 18 is provided between the first synchronous pulley 16 and the second synchronous pulley 17.

[0032] A movable component is provided on one side of the screening frame 1, and the output end of the movable component is connected to a movable block 20. The movable block 20 is fixedly connected to one of the card seats 11.

A threaded rod 9 is rotatably connected between the two fixed seats 8 via a bearing. A first motor 10 is fixed to the side wall of one of the fixed seats 8. The output end of the first motor 10 is connected to the threaded rod 9. The movable block 20 is connected to the outside of the threaded rod 9 via a threaded engagement.

[0034] During vibrating screening, the first motor 10 can be started, causing the threaded rod 9 to rotate. Then, the threaded rod 9 drives the movable block 20 to move, causing the movable block 20 to drive the card seat 11 to slide on the screening frame 1. This allows the card seat 11 to drive the connecting shaft 14 to move back and forth within the screening frame 1. At the same time, the second motor 19 is started, causing the second synchronous wheel 17 to rotate. Then, the second synchronous wheel 17 drives the first synchronous wheel 16 to rotate via the synchronous belt 18. This causes the first synchronous wheel 16 to drive the connecting shaft 14 to rotate. Afterward, the connecting shaft 14 can drive multiple sets of material-pushing plates 15 to rotate. The material-pushing plates 15 can lift the material on the screening screen 2. As the material-pushing plates 15 move back and forth, the upper and lower layers of material can be effectively separated and dispersed, which is beneficial for the flow of tobacco and greatly improves the vibrating screening efficiency of tobacco.

[0035] A slider 12 is provided on the inner side of the card holder 11, and a groove 13 matching the slider 12 is provided on the top side of the screening frame 1. By setting the slider 12 and the groove 13, the card holder 11 can drive the slider 12 to slide in the groove 13, thereby greatly improving the stability of the card holder 11 when it moves.
