Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a stem removal device. Background Art

[0002] The shapes of tobacco stems separated by wind after redrying are different. The stems with one end larger than the other are usually called stem tips or stem tips. The stem tips in raw tobacco stems have the characteristics of wide cross-section, high hardness, poor water absorption and difficulty in wetting. In the continuous production process, the stem tips that are not removed in time are mixed into the finished stems and cannot be completely wetting. The stem tips entering the stem cutting machine are prone to problems such as stem running, large fluctuations in the thickness of the cut stems, and high stem content in the stems. Some stem tips are eventually mixed into the finished tobacco, which directly affects the efficiency of cigarettes, changes the taste of cigarettes, or causes the cigarettes to extinguish naturally during lighting, which has an adverse effect on the quality of cigarettes and brings great difficulty to the quality control of the workshop production process.

[0032] like Figure 1 As shown, in one embodiment of the utility model, a device for removing stems and turns is proposed, comprising: a vibrating conveyor 2, a screen 3 and a combing device 4; the vibrating conveyor 2 comprises a rocker arm 23 and a trough body 21, the rocker arm 23 is connected to the trough body 21 and can drive the trough body 21 to vibrate; the screen 3 comprises a plurality of screen rods 31 arranged in parallel, the plurality of screen rods 31 are installed in the trough body 21 and can vibrate together with the trough body 21, and there are set gaps between the screen rods 31; the combing device 4 is arranged on the screen 3, the combing device 4 comprises a transmission chain 42 and combing teeth 41, the combing teeth 41 are installed on the transmission chain 42, and the thickness of the combing teeth 41 is less than the gap between the screen rods 31, as shown in FIG. Figure 7 As shown, the transmission chain 42 can drive the combing teeth 41 to move from the gaps between the screen bars 31 .

[0033] In the tobacco stem removal device of the utility model, a combing device 4 is arranged on the screen 3. By making the running direction of the combing teeth 41 of the combing device 4 consistent with the material flow direction, when a tobacco stem is stuck in the gap of the screen 3, it will be pushed forward or fall off by the combing teeth 41 moving forward (the ones that fall off are tobacco stems that meet the requirements), and the tobacco stems stuck in the gap are removed in time to ensure the smooth flow of the stem falling channel, effectively avoid the phenomenon of stem jamming, realize automatic cleaning of the screen 3, and ensure the screening effect of the tobacco stems.

[0034] like Figure 1 , Figure 2 As shown, one end of the tank body 21 (i.e. Figure 1 The left end of the tank body 21 is provided with a material inlet. Figure 1A tobacco stem discharge port 214 is provided at the middle right end of the trough body 21, and a material leveling plate 211 is provided at the lower side of the material inlet. The tobacco stem discharge port 214 is lower than the screen 3 in the vertical direction. Along the material moving direction (i.e. from left to right), a discharge connection plate 212 is provided at the rear side of the screen 3, and a stem turn discharge plate 213 is provided at the rear side of the discharge connection plate 212. The stem turn discharge plate 213 is arranged obliquely (such as Figure 3 As shown in the figure, one end of the stem discharge plate 213 extends out of the trough body 21 from the side of the trough body 21. When the tobacco stems are vibrated and transported forward, the long strips of tobacco stems fall into the bottom of the trough body 21 from the gaps in the screen 3 and enter the next process from the right tobacco stem discharge port 214, while the stems mixed in them cannot be leaked and can only be transported forward on the screen 3. Finally, the stems are discharged from the side of the trough body 21 through the discharge connecting plate 212 and the stem discharge plate 213, thereby achieving the purpose of purifying the quality of the tobacco stems.

[0035] The vibrating conveyor can adopt the existing structure, such as Figure 1 As shown, the vibrating conveyor 2 also includes a frame 24, a balancing frame 22 and an exciting device. The middle part of the rocker arm 23 is connected to the frame 24, the upper end of the rocker arm 23 is connected to the trough body 21, and the lower end of the rocker arm 23 is connected to the balancing frame 22.

A mounting hole is provided on the upper side of the fixed seat 33. The lower end of the support column 32 is installed in the mounting hole of the fixed seat 33. The screen rod 31 is installed on the support column 32.

[0037] According to the test, the size and flow requirements of the stems to be removed are determined, and the screen 3 grid bars are used. The size specifications of the screen 3 (i.e. the size of the gap) determined according to the tobacco stem raw material conditions, actual measurements, and tests can adapt to tobacco stems of different specifications in various places and effectively remove the stems.

[0038] like Figure 5 As shown, the transmission chain 42 is annular, and a plurality of combing shafts are arranged on the annular transmission chain 42. One end of the combing teeth 41 is fixed on the combing shaft, and the other end is arranged toward the outside of the transmission chain 42. Figure 5 In the embodiment, the combing teeth 41 located at the upper side have their ends facing upwards; the combing teeth 41 located at the lower side have their ends facing downwards. The combing teeth 41 rotate counterclockwise. When the combing teeth 41 rotate to the lower side, they move from left to right, thereby cleaning the tobacco stems stuck in the gaps of the screen 3. Further, as Figure 4 , Figure 5As shown, a plurality of combing teeth 41 are arranged on each combing shaft of the transmission chain 42. The combing teeth 41 on different combing shafts are arranged in a staggered manner perpendicular to the moving direction of the combing teeth 41, that is, the combing teeth 41 on each combing shaft correspond to a part of the gap. By staggering the combing teeth 41 on the combing shafts, the stems in all the gaps are cleaned. The shape of the combing teeth 41 is as shown in FIG. Figure 5 As shown, both sides of the outer end of the combing tooth 41 are arc-shaped surfaces, the front side of the combing tooth 41 is a concave arc-shaped surface, and the rear side of the combing tooth 41 is a convex arc-shaped surface. The combing teeth 41 of this shape can push the stems that do not meet the requirements to the discharge connecting plate 212 on the rear side.

[0040] In another embodiment, a visual monitoring system may be provided in the protective cover 1, and the visual monitoring system includes a mounting frame and a camera, the camera is mounted on the mounting frame, and the camera is arranged toward the screen 3. The visual monitoring system monitors the screen 3 in real time through the camera, and the PLC continuously compares the collected images. When the area of ​​the stalk jam exceeds 1 / 5, the screen 3 cleaning device is controlled to clean the screen 3 to ensure the stalk removal effect of the screen 3.

[0041] The working principle of the above-mentioned stem removal equipment:

[0042] The tobacco stems enter the stem removal device and are vibrated and transported forward under the action of the excitation device. The long strips of tobacco stems that meet the requirements can fall from the gaps in the screen 3 to the bottom of the tank body 21 and enter the next process. The mixed stems cannot be missed and can only be transported forward on the screen 3. When the stems are stuck in the gaps in the screen 3, the combing device 4 is controlled to start. Its running direction is consistent with the material flow direction. The jammed stems will be pushed forward or fall off by the combing teeth 41 driven by the transmission link, and finally discharged from the stem discharge port located on the side of the tank body 21 through the stem discharge plate 213. The dust caused by the transportation of tobacco stems inside the equipment is discharged and processed by the dust removal system 11. The operation of the equipment can be observed through the transparent observation window 12 on the top. If there is a problem, it can be handled through the inspection door 13 to ensure the safe and stable operation of the equipment.
