Description
Technical field
The present invention relates to a kind of tobacco leaf screening plant, especially a kind of gamma-rays tobacco leaf screening plant, belong to technical field of tobacco processing.
Background technology
In tobacco working process, the control of the offal content in tobacco leaf directly affects the final mass of cigarette.In the U of Publication No. CN 203725397 Chinese patent, it is proposed that a kind of offal detection and device for eliminating, be that raw tobacco material is taken a picture using X-ray, by analyzing the images to reject offal, this monitoring mode has the following disadvantages：1）X-ray source and X-ray detector equipment are expensive；2）Radiograph is carried out to the raw tobacco material slid, the easily formation to image interferes, and causes accuracy of detection to be difficult to improve.Therefore, it is necessary to prior art is improved.
The content of the invention
It is an object of the invention to provide a kind of gamma-rays tobacco leaf screening plant, to reduce the cost of tobacco leaf screening plant, while improves screening precision.
To realize the purpose, present invention employs following technical scheme：
A kind of gamma-rays tobacco leaf screening plant, including ingredient conveyor, swash plate, gamma ray radiator, gamma ray detector, single-chip microcomputer, hair-dryer, separate platform, offal conveyer, tobacco conveyer, offal collecting tank, tobacco leaf collecting tank.The raw tobacco material that ingredient conveyor is blended with offal is transported to swash plate upper end, during raw material glides along swash plate, the gamma-rays sent by gamma ray radiator irradiates, gamma ray detector receives and the gamma-rays after raw material effect, and it is converted into pulse signal and single-chip microcomputer is delivered to by wire, single-chip microcomputer is by being calculated the density of raw material and judging, because offal is different with the density of tobacco leaf, once detect in raw material with the presence of offal, single-chip microcomputer can send instruction and start hair-dryer, raw material containing offal is blown to the left side for separating platform by hair-dryer during raw material is dropped downwards by swash plate end, offal collecting tank is transported to by offal conveyer, not having offal in raw material, then hair-dryer does not start, raw material, which drops, to be separated on the right side of platform, tobacco leaf collecting tank is transported to by tobacco conveyer, realize the separation of tobacco leaf and offal.
Present invention contrast prior art has the following advantages：Gamma-rays light source and gamma ray detector equipment price are relatively low, reduce production cost；And single-chip microcomputer judges that offal whether there is by detecting material density rather than image, so as to avoid raw material motion interference to caused by the formation of image, screening precision is improved.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the schematic diagram of the present invention.
101. ingredient conveyor in figure, 102. offal conveyers, 103. tobacco conveyers, 104. swash plates, 105. gamma ray radiators, 106. gamma ray detectors, 107. single-chip microcomputers, 108. hair-dryers, 109. separate platform, 110. offal collecting tanks, 111. tobacco leaf collecting tanks.
Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
In Fig. 1, gamma ray radiator（105）And gamma ray detector（106）It is located at swash plate respectively（104）Both sides, ingredient conveyor（101）The raw tobacco material for being blended with offal is transported to swash plate（104）Upper end, raw material is along swash plate（104）During downslide, by gamma ray radiator（105）The gamma-rays irradiation sent, gamma ray detector（106）The gamma-rays after being acted on raw material is received, and is converted into pulse signal and single-chip microcomputer is delivered to by wire（107）, single-chip microcomputer is by being calculated the density of raw material and judging, because offal is different with the density of tobacco leaf, once detect in raw material with the presence of offal, single-chip microcomputer（107）Instruction can be sent and start hair-dryer（108）, hair-dryer（108）Positioned at swash plate（104）Lower right is with separating platform（109）The space in upper right side, air port is towards lower left, hair-dryer（108）In raw material by swash plate（104）Raw material containing offal is blown to separation platform by end during dropping downwards（109）Left side, pass through offal conveyer（102）It is transported to offal collecting tank（110）, there is no offal then hair-dryer in raw material（108）Do not start, raw material, which drops, is separating platform（109）Right side, pass through tobacco conveyer（103）It is transported to tobacco leaf collecting tank（111）, realize the separation of tobacco leaf and offal.
Gamma-rays light source and gamma ray detector equipment price of the present invention are relatively low, reduce production cost；And single-chip microcomputer judges that offal whether there is by detecting material density rather than image, so as to avoid raw material motion interference to caused by the formation of image, screening precision is improved.
