Embodiment 1

[0024] like figure 1 , 2 As shown in and 4, the present invention provides a negative pressure tobacco leaf visual double-sided detection device, including a negative pressure perforated conveyor belt 1, a second conveyor belt 2, a negative pressure chamber 3, a negative pressure fan 4 and a visual detection device 5. figure 1 The first side of the middle tobacco leaf 6 is represented by a black part, and the second side is represented by a white part.

[0025] The negative pressure perforated conveyor belt 1 includes a conveying roller 7 and a perforated belt 8 wound on the conveying roller 7, and the surface of the perforated belt 8 is uniformly provided with a number of ventilation holes. The negative pressure chamber 3 is arranged on the inside of the discharge end of the negative pressure perforated conveyor belt 1, and the negative pressure fan 4 is installed on the air outlet of the negative pressure chamber 3 to generate negative pressure. The surface of the pressure...

Embodiment 2

[0029] like image 3 , 4 As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the negative pressure punching conveyor belt 1 and the negative pressure chamber 3 at the discharge end. The discharge end is provided with at least two conveying rollers 7, and the perforated belt 8 of the discharge end is attached to the upper and lower sides of the negative pressure chamber 3 and the side facing the discharge end. Two of the conveying rollers 7 at the discharge end are respectively arranged at the upper and lower ends of the negative pressure chamber 3 facing the discharge end. The side of the negative pressure chamber 3 facing the discharge end is rectangular, and the edge adopts a rounded structure to facilitate the smooth transportation of the tobacco leaves 6. The radius of the rounded corner is equivalent to the radius of the conveying roller 7 set here.

Embodiment 3

[0031] The structure of this embodiment is similar to that of Embodiment 2, the difference is that the side of the negative pressure chamber 3 facing the discharge end is a semicircular arc surface.

Abstract

The invention discloses a visual double-sided detecting device for tobacco leaves with a negative pressure, and a detecting method thereof. The double-sided detecting device comprises a negative pressure punching conveyor belt, a second conveyor belt, a negative pressure chamber, a negative pressure fan, and a visual detecting device. The negative pressure punching conveyor belt comprises a conveying roller and a punching belt wound around the conveying roller. The surface of the punching belt is evenly provided with a plurality of ventilation holes. The negative pressure chamber is disposed inside the discharge end of the negative pressure punching conveyor belt. The suction port of the negative pressure chamber is mounted with the negative pressure fan. The negative pressure chamber anda surface contacting the inner side of the punching belt are provided with an air inlet. The second conveyor belt is disposed under the negative pressure punching conveyor belt. The feeding end of thesecond conveyor belt is located at a side of the negative pressure chamber away from the discharge end. The visual detecting devices are provided on both the negative pressure punching conveyor beltand the second conveyor belt. The visual double-sided detecting device for tobacco leaves with the negative pressure improves the recognition effect on mildew tobacco leaves and low grade tobacco leaves.

Description

technical field [0001] The invention relates to the field of tobacco leaf production, in particular to a negative-pressure tobacco leaf visual double-sided detection device and a detection 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 sorting of moldy tobacco leaves and low-grade tobacco leaves cannot be completed by selectio...
