Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco processing equipment, and specifically relates to a stem cutting device. Background Technology

[0002] Tobacco stems are a crucial raw material for cigarette processing enterprises, accounting for approximately 25% of the total weight of tobacco leaves. Scientific and efficient processing of tobacco stems can reduce the tar content of cigarettes and improve rolling quality. Furthermore, to fully utilize raw materials and reduce waste, tobacco stems are used in cigarettes of all grades. However, tobacco stems entering the tobacco stem processing line in cigarette factories often contain stem stalks. These stalks differ significantly from normal tobacco stems in shape, composition, and properties, making them difficult to process. Their presence affects the stability of the tobacco stem quality and easily leads to stem sticking, necessitating their removal. Current stem stalk removal equipment includes flat vibrating screens and circular rotary screens, both of which are easily clogged by stem stalks, rendering them ineffective for screening. Therefore, a new method and device for removing stem stalks are needed to eliminate screen clogging and achieve efficient stem stalk removal. Utility Model Content

[0025] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of this utility model, and should not be construed as limiting the technical solution of this utility model.

[0026] The technical solution of this application adopts a method combining an online screening vibrating conveyor and a cutting device. The cutting device is installed on the screening vibrating conveyor, which simultaneously screens the tobacco stems online and removes useless stem clippings, leaving the usable tobacco stems carried on the clippings. This solves the problems of stem clippings clogging the mesh and the difficulty in removing stem clippings during online screening, thereby improving yield and reducing production costs.

[0027] like Figures 1 to 4 As shown, this utility model consists of a screening vibrating conveyor and a cutting device. The screening vibrating conveyor is identical in structure and principle to common screening vibrating conveyors; however, because a thorn cutting device needs to be installed on the vibrating trough, its structure, balance body, and transmission system require recalculation, design, and fabrication. The thorn cutting device is mounted on the trough 21 of the vibrating conveyor via a bracket 4 and a reducer bracket 8, and moves together with the trough 21.

[0028] The spur removal device of this application includes multiple supports, a moving assembly, a cutting assembly, a reducer support, and a detection switch. The supports 4 and the reducer support 8 are respectively installed on both sides of the trough 21 to support the entire removal device and drive the removal device to move together with the trough of the vibrating conveyor.

[0029] The moving assembly of this application mainly consists of a reducer 9, a drive shaft 20, a synchronous belt 14, synchronous pulleys 16, a driven shaft 18, a guide rail 13, a guide rail sleeve 12, and a detection switch. The reducer 9 is mounted on a reducer bracket 8. The drive shaft 20 and the driven shaft 18 are mounted on a bracket 4 via bearings, located above the groove. The reducer 9 is connected to the drive shaft 20 via a coupling and drives the drive shaft 20 to rotate. Four sets of synchronous pulleys 16 are respectively mounted at both ends of the drive shaft 20 and the driven shaft 18. The two ends of the two synchronous belts 14 are respectively fixed to the tool holders on both sides and mounted on the synchronous pulleys 16 on the drive shaft 20 and the driven shaft 18. Through the two synchronous belts 14, the rotational motion of the reducer is converted into the left-right reciprocating movement of the cutting assembly. Two guide rails 13 are respectively mounted on the bracket 4, positioned above the two sides of the groove 21; the guide rail sleeve 12 is fitted onto the guide rail 13 and can move on the guide rail 13; the tool holder 11 is mounted on the guide rail sleeve 12 and moves left and right together with the cutting assembly under the drive of the synchronous belt 14.

[0030] The cutting assembly mainly consists of a tool holder 11, a tool holder rod 19, a tool holder 7, a cutting blade 6, a pressure plate 22, and screws 23. Two sets of tool holders 11 are respectively mounted on the guide rail bushings 12; the tool holder rod 19 is mounted on the tool holder 11; the tool holder 7 is mounted on the lower plane of the tool holder rod 19, located below the tool holder rod 19, and its length is appropriately smaller than the width of the inner side of the groove 21, allowing it to reciprocate within the groove 21; the lower end of the tool holder 7 has a side plate for mounting the cutting blade 6, which is symmetrically arranged; the pressure plate 22 is fixed to both sides of the lower end of the tool holder 7 by screws 23, and applies a holding force to the cutting blade 6, ensuring that the cutting blade 6 can smoothly cut away the stem; the cutting blade 6 can be quickly replaced by removing and installing the screws 23 and the pressure plate 22. The cutter holder 7 has a hollow structure with evenly distributed through holes 24. Its function is to allow the material on the screen to easily pass through the through holes 24 when the cutter holder 7 moves, without affecting the normal movement of the material.

[0031] Working principle:

[0032] After the tobacco stems enter the screening vibrating conveyor, under the resonance of the conveyor, they are transported forward. The stems fall through the mesh onto the lower bottom plate 1 and exit from the front outlet of the conveyor, proceeding to the next process. Because the cross-sectional area of ​​the stem bend is larger than the mesh, it cannot pass through the mesh to fall to the lower layer. During its forward movement under the resonance of the conveyor, a section of the stem bend (the tobacco stem segment) gets stuck in the mesh and cannot move.

[0033] The stem cutting device starts operating together with the screening vibrating conveyor. Driven by the reducer 9, the device transmits power through the drive shaft 20, synchronous pulley 16, synchronous belt 14, and cutter holder 11, causing the cutter holder 7 and cutting blade 6 to move horizontally back and forth, cutting the stems inserted into the mesh. The portion that meets the requirements of the tobacco stem is cut off and falls onto the bottom plate 1, entering the next process with the tobacco stem. The stem portion can then move back onto the screen and be discharged from the stem outlet 2, falling into the stem box. When the cutting blade 6 moves to one end, it is detected by the detection switch 10 or 15, causing the reducer to reverse direction and the cutting blade 6 to move in the opposite direction. Under the detection control of the left and right detection switches 10 and 15, the cutting blade 6 moves back and forth, continuously cutting the stems and completing the stem cutting operation.

[0034] The reciprocating speed and frequency of the cutting blade can be adjusted according to the different tobacco stem brands.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
