Embodiment 1

[0026] Such as Figure 1-4 As shown, the present invention provides a tobacco leaf negative pressure separation device that can work continuously, including an operating platform conveyor belt 5, a negative pressure perforating belt 1, a visual detection conveyor belt 4, a negative pressure chamber 2 and a negative pressure fan 3. The operating platform conveyor belt 5 is a conveyor belt for feeding, and the visual detection conveyor belt 4 is a conveyor belt for discharging. The pulleys of the operating platform conveyor belt 5, the negative pressure punching belt 1 and the visual detection conveyor belt 4 are installed on the machine platform or the wall through the rotating shaft, wherein the driving pulley is connected with the motor drive through the transmission mechanism.

[0027] The negative pressure perforated belt 1 is arranged obliquely, and the feed end of the visual inspection conveyor belt 4 is arranged on the lower belt side of the negative pressure perforated ...

Embodiment 2

[0032] Such as Figure 1-3 , 5, the difference between this embodiment and embodiment 1 lies in the structure of the air inlet 10. In this embodiment, the air inlet surface 9 is provided with a number of air inlets 10, the air inlets 10 are arranged along the length direction of the air inlet surface 9, and the width of the separating beams between adjacent air inlets 10 is smaller than the standard length of tobacco leaves. In this way, the partition beams can correspond to the intervals between the perforated areas 8, thereby ensuring that useless air inlets 10 areas are reduced during the adsorption process, and energy can be saved without affecting the separation and thinning effects.

[0033] The invention also provides a tobacco leaf negative-pressure separation method corresponding to the above-mentioned tobacco leaf negative-pressure separation equipment capable of continuous operation. This separation method comprises the steps:

[0034] Step 1, the tobacco leaves a...

Abstract

The invention discloses negative pressure separating equipment capable of continuously working for tobacco leaves and a separating method. The negative pressure separating equipment for the tobacco leaves comprises an operation platform conveying belt, a negative pressure perforating belt, a visual inspection conveying belt, a negative pressure cavity and a negative pressure fan, wherein the negative pressure perforating belt is obliquely arranged; the feeding end of the visual inspection conveying belt is arranged on one side of the lower belt surface of the negative pressure perforating beltand is positioned below the discharging end of the negative pressure perforating belt; the operation platform conveying belt is positioned on one side of the upper belt surface of the negative pressure perforating belt; a clearance for the tobacco leaves to pass is reserved between the operation platform conveying belt and the upper belt surface; the negative pressure cavity is arranged at the bottom of the upper belt surface along the direction of the negative pressure perforating belt; the belt surface of the negative pressure perforating belt is provided with a plurality of ventilation holes corresponding to the air inlet surface of the negative pressure cavity; the negative pressure cavity is also provided with an exhaust inlet for mounting the negative pressure fan. The negative pressure separating equipment disclosed by the invention separates the curved tobacco leaves, can effectively spread the tobacco leaves to single layer and has a good spreading effect.

Description

technical field [0001] The invention relates to the field of tobacco leaf production, in particular to a continuously working tobacco leaf negative pressure separation device and a separation method. Background technique [0002] In the tobacco shredded production line, threshing and redrying production line, it is the key process to ensure the quality of cigarettes to efficiently and accurately remove heavy foreign matter, light foreign matter, mildewed tobacco leaves, and low-grade tobacco leaves in the tobacco leaves to improve the purity of tobacco leaves. At present, tobacco companies mostly adopt the method of winnowing for separation, and use the tobacco leaves to be suspended in the sorting box under the lifting action of the airflow to realize the sorting of heavy foreign matter. This is more effective for sorting and removing foreign matter in the tobacco leaves, but windy The selection cannot complete the sorting of curly tobacco leaves, nor can the sorted tobacco...
