Description

Tobacco leaf rod penetrating device convenient for collecting aroma components

Technical Field

The invention belongs to the field of tobacco planting, and particularly relates to a tobacco leaf rod penetrating device convenient for collecting aroma components.

Background

The method has the advantages that the influence of the severe weather environment on the growth of tobacco plants is eliminated, the quality of tobacco leaves produced by the tobacco plants of the flue-cured tobacco variety is mainly influenced by two aspects of field management and baking modulation, the field management mainly manages the growth of the tobacco plants, and the stage comprises the steps of transplanting, fertilizing, pest control, topping and the like, so that the uniform yellowing and uniform harvesting of the tobacco leaves in the same part and the tobacco leaves in the same land are ensured; the baking modulation mainly heats the tobacco leaves harvested in the field, so that the tobacco leaves are dehydrated, the internal components are chemically converted and reacted in the environment, the contents of various components are more coordinated, and particularly, the Maillard reaction can improve the generation of the internal aroma components, thereby improving the appearance and the smoking quality of the tobacco leaves.

Generally, the tobacco leaf baking in the prior art basically adopts a three-stage baking process of bulk curing barn operation, i.e. the tobacco leaves need to undergo a yellowing stage, a color fixing stage and a stem drying stage, and the principle is as follows: tobacco leaves are hung inside the curing barn in a layered mode, then the curing barn is externally heated by coal and heat exchange between the combustion chamber and the curing barn is realized through a pipeline, hot air flow inside the curing barn rises to heat the tobacco leaves, and meanwhile, discharged water is carried to the outside. Because the quantity of the tobacco leaves in the curing barn is large, how to regulate the tobacco filling mode of the tobacco leaves enables hot air to flow in the curing barn uniformly, the method is one of necessary conditions for high-level curing and modulation, otherwise, insufficient water drainage and insufficient heating are easily caused, the tobacco leaves are difficult to fix color, even the phenomena of rib feathering, grain bleeding, ash hanging and the like of the tobacco leaves occur, not only heat energy is wasted, but also the purchasing price and the use quality of the tobacco leaves at the grade are extremely low.

The cigarette loading mode in the prior art is divided into three types: tobacco stem, cigarette clamp and cigarette frame, the tobacco leaf is placed in disorder in cigarette clamp and the cigarette frame, but dress cigarette is efficient, be fit for factory formula and toast modulation operation, the tobacco stem utilizes the cotton rope to compile the tobacco leaf and ties up on the bamboo pole, then hang into a supporting beam in the baking house with the bamboo pole layering on, this kind of dress cigarette mode is comparatively traditional, though toast the effect better than cigarette clamp and cigarette frame, but extremely take the manual work, and work efficiency is low, manual work is compiled the cigarette simultaneously and is caused a large amount of friction injuries between the tobacco leaf easily, and also unable accurate control tobacco leaf range interval, and then can not improve the even speed that the hot gas flow flows by a wide margin yet, the smoothness nature.

At present, the stage judgment of tobacco leaf baking is basically observed by naked eyes, namely, the tobacco leaf baking is observed through a glass window arranged on a baking room, but the glass window is easily polluted by water vapor to cause the light transmittance to be reduced, but the glass window is not suitable for opening a door of the baking room to wipe the door, so that certain errors exist in the stage judgment of the baking. Because the tobacco leaf is in different toasting stages, the fragrant composition that it gave out is different, so have the scholars to propose through the kind of the fragrant composition in the roast room and judge what kind of stage that the tobacco leaf is in toasting, but this all is comparatively stable based on the inside and outside air current of sending of roast room, and can smoothly circulate between the tobacco leaf, otherwise fragrant composition content is too little, can not realize this technical scheme's implementation at all.

Specifically, in the tobacco loading process of the tobacco leaves, the whole process of the invention is as follows (the limited direction is as follows, the positive rotation of the output end of the motor can enable the transmission belt to drive the negative pressure suction nozzle to move towards the placing rack, and the negative rotation of the output end of the motor can enable the transmission belt to drive the negative pressure suction nozzle to move reversely):

the staff stacks the tobacco leaf with the tobacco leaf syntropy and advances in the tobacco pipe, and the leaf surface of tobacco leaf is down and the tobacco leaf falls on the wheel face of the supporting wheel of two die-pins under the dead weight effect promptly, and the supporting wheel supports the tobacco leaf blade, and the both sides limit contact supporting wheel of tobacco leaf width direction promptly supports. Then the motor and the exhaust fan are started, the exhaust fan extracts air in the bending pipe and the negative pressure suction nozzle, the channel on the bending pipe is shielded by the adhesive tape piece while the negative pressure suction nozzle is shielded by tobacco leaves, so a negative pressure state can be kept in the bending pipe and the negative pressure suction nozzle, the negative pressure suction nozzle continuously sucks the air above the bending pipe, when the negative pressure suction nozzle moves to the position under the tobacco leaf pipe, the lowest tobacco leaf in the tobacco leaf pipe is sucked and moves downwards, particularly the middle section of the width direction of the tobacco leaf surface is not in direct contact with the supporting wheel, so the tobacco leaf is pulled downwards most and moves downwards, the tobacco leaf moves relative to the supporting wheel (namely the supporting wheel rolls under the action of friction), the tobacco leaf is separated from the supporting wheel and covers the silica gel suction nozzle of the negative pressure suction nozzle, the protruded leaf vein on the tobacco leaf is positioned on the back surface, and the front surface is smooth, so the silica gel suction nozzle can be better shielded, therefore, after the current tobacco leaf is adsorbed by the negative pressure suction nozzle, the suction effect of the negative pressure suction nozzle on other tobacco leaves disappears. When the negative pressure suction nozzle continues to move along with the transmission belt, the negative pressure suction nozzle drives the exhaust pipe to move along the channel on the bent pipe, so that the inside of the negative pressure suction nozzle is always communicated with the inside of the bent pipe and keeps a negative pressure state, meanwhile, the exhaust pipe can extrude the adhesive tape piece at the current position when moving, and the adhesive tape piece at the previous position still keeps shielding the channel.

When the negative pressure suction nozzle moves to the lowest placing plate, the shifting plate on the shifting plate mechanism just moves upwards to push the placing plate to the maximum vertical height, the negative pressure suction nozzle moves downwards to a certain distance below the placing plate from the first notch of the placing plate, tobacco leaves adsorbed by the negative pressure suction nozzle are intercepted by the plate body of the placing plate at the first notch, so that the tobacco leaves are placed in the placing plate, meanwhile, the tobacco leaves slide downwards along the top plate surface of the placing plate under the action of gravity due to the fact that the placing plate is obliquely arranged, and the tobacco leaves can smoothly enter the groove of the placing plate; meanwhile, when the negative pressure suction nozzle moves downwards to penetrate through the first notch, the shifting plate can continue to move upwards along with the belt, the shifting plate is separated from the current placing plate at the moment, the placing plate moves downwards along the through hole under the action of self weight, and the depth of the groove is only 1-2mm, so that the leaves of the tobacco leaves can be completely placed in the groove, and the main vein of the tobacco leaves can be exposed outside the groove.

The motor reversal afterwards, the drive belt drives negative pressure suction nozzle reverse movement, because the tobacco leaf moves down along placing the board and along with placing the board from the initial position that the board was placed in the contact and moving down, its whole displacement is the lapse, so when placing the board along the through-hole back that the process that moves down finishes, the reverse movement of negative pressure suction nozzle can not blockked in the instant position of tobacco leaf. When negative pressure suction nozzle reverse movement and reach into the tobacco pipe under, the negative pressure suction nozzle adsorbs the tobacco leaf that advances the intraductal bottommost of cigarette again, then negative pressure suction nozzle removes to the bottommost place the board department of placing above the board, the operation is placed to repeated tobacco leaf, so the circulation is reciprocal, all place the blade of newly absorbing at every turn on the board is placed to the correspondence, and every places the board and all drive its tobacco leaf removal of accepting, make the tobacco leaf all keep its main arteries and veins to paste and lean on to place board plate body department and place, and the petiole exposes to the board of placing outward from second breach department completely. Then the worker stops the motor to work, the pull frame is driven to pull outwards through the handle, the pull frame drives all the pricking pins on the groove rail to move along the groove rail, the pricking rod on the outermost side moves upwards along the opening end of the groove rail and finally moves out of the opening section of the groove rail, the action of the pricking rod is observed through the observation gap, when the pull handle stops being pulled when the pull handle falls and is moved out of the rod outlet of the box body, the binding rod is downwards bound from the second gap of the placing plate, the tobacco leaves sequentially pass through the leaf stalks of the tobacco leaves from top to bottom through the sharp bottom, then the binding rods are slightly lifted upwards, so that the tobacco leaves are separated from the placing plate, the limiting rods are completely attached to the plate body of the placing plate after the main veins of the tobacco leaves are not blocked, namely, the tobacco leaves are not blocked by the upper limiting rod any more, the binding rod can be continuously lifted and all the tobacco leaves are driven to be taken out from the tobacco outlet of the machine case, the tobacco leaves on the binding rods can be distributed at equal intervals, and then the binding rods are orderly hung on a hanging beam of a curing barn to finish the tobacco loading.

The main veins of the tobacco leaves can be forced to be pressed at the through hole due to the falling of the placing plate, so that the end parts of the stems of the tobacco leaves on the placing rack are basically positioned on the same vertical line, the sharp-pointed parts of the binding rods can be accurately bound on the stems of the tobacco leaves, and the situation that the binding positions are different due to different sizes of the tobacco leaves is avoided. It should be noted here that the tobacco leaves are different from other crop leaves, the harvesting is divided into three batches of lower, middle and upper leaves, and the tobacco leaves are baked and modulated immediately after each harvesting, so the size difference of the tobacco leaves in the same batch is not particularly large, the tobacco leaves are large in size, the width of the main vein, particularly the end part of the vein, namely the leaf stalk, can reach 1-2cm, the thickness can reach 0.8-1.5cm, compared with the tobacco leaf with the thickness of 1-2mm, the main vein and the leaf stalk can completely bear the weight of the tobacco leaves, meanwhile, the main vein and the leaf stalk are used in the cigarette industry after modulation as tobacco stems, the value of the main vein and the leaf stalk is lower than that of the tobacco leaves, namely the tobacco shreds after the tobacco leaf stalks are modulated, the economic value is lower, and the main vein is.

Secondly, in the process, the transmission matching process of each mechanism of the application is as follows:

the invention only needs one motor as a power source to realize the orderly matching action of all the mechanisms, the output end of the motor rotates forwards for a certain time and drives the driving wheels at the horizontal section and the inclined section of the transmission belt to rotate, and the driving wheels drive the other two driving wheels and the negative pressure suction nozzle to move through the transmission of the transmission belt; meanwhile, the driving wheels at the vertical section and the inclined section of the driving belt drive the first driving rod to rotate positively, when the ratchet wheel at the end part of the first driving rod rotates positively, the pawl abuts against the wheel teeth of the ratchet wheel, the ratchet wheel drives the sleeve to rotate positively, and then the indirect wheel is driven to rotate positively through the indirect belt, and as the indirect wheel drives the belt pulley of the shifting plate mechanism and the corresponding belt to rotate positively through the second driving rod, the shifting plate close to the belt section at the placement frame is enabled to move upwards, and the shifting plate far away from the belt section at the placement frame is enabled to move downwards.

The in-process that the board that dials that is close to rack department belt section shifts up, the board roof of placing of the bottom on the rack can be contacted, because the roof of placing the board with dial the board parallel, so work as dial the board and shift up and contact when this roof of placing the board, make the roof drive and place the board and remove along corresponding through-hole, when dialling the board base and remove to the roof topside, the roof top of placing the board touches the through-hole, the displacement that makes progress of placing the board at this moment reaches the terminal point, dial the board and continue to move up the back, its roof separation with this place the board, this place the board and move and reset along the through-hole under the dead weight effect, dial the board of placing of board contact top simultaneously and make it shift up along the through-. So, along with shifting up of dialling the board, can push up in order and touch every and place the board for place the board on the rack by the lower supreme action of moving up and reseing in order, accomplish this action until the board of placing at top.

Meanwhile, the action of the shifting plate is driven by the connected belt, the transmission of the belt is indirect transmission based on the transmission belt, if the transmission belt moves forwards, the belt moves forwards, and if the transmission belt moves backwards, the belt moves backwards, and particularly the action of the shifting plate is up-and-down movement. But want to keep dialling the effect that the board pushed the board from bottom to top in order, dial the board and can only move up at the uniform velocity so, and can not do and move down, otherwise only can realize the relapse promotion to a certain board of placing. Therefore, the problem is solved through the one-way transmission mechanism, when the transmission belt moves forwards, the transmission wheel can finally realize the forward rotation of the belt and move the shifting plate upwards through the matching of the ratchet wheel and the pawl; when the transmission belt moves reversely, the ratchet gear rotates reversely and enables the pawl to rotate under the action of the torsion spring, and the sleeve cannot be driven to rotate reversely (because the sleeve and the indirect wheel tension the indirect belt, the friction force of the sleeve driving the indirect belt to rotate needs to be large enough, although the ratchet gear and the pawl have collision, the collision is far not enough to enable the sleeve to drive the indirect belt to rotate), and then the non-displacement action of the indirect belt, the indirect wheel and the plate shifting mechanism is realized. Therefore, the action of the shifting plate close to the placing plate can only be ensured to be upwards moved.

However, only by means of the one-way transmission device, the shifting plate can only move upwards, and the displacement cannot be guaranteed, so that the displacement of the shifting plate moving upwards at each time is guaranteed, and the placing plates on the placing frame are arranged at equal intervals, so that the tobacco leaves can be arranged at equal intervals on the binding rods. However, when the original position of the negative pressure suction nozzle is taken as a marking point, the positive movement amount of the negative pressure suction nozzle driven by the transmission belt every time is progressively reduced, namely, the negative pressure suction nozzle moves to the bottommost placing plate from the original position, and moves positively for the second time after reset, the negative pressure suction nozzle moves to the penultimate placing plate from the original position, the positive linear movement of the transmission belt is reduced, the number of rotation turns of the transmission belt is reduced, the positive belt linear movement of the plate shifting mechanism is reduced, the upward movement amount of the plate shifting mechanism is reduced, and finally the plate shifting mechanism cannot be smoothly matched with the action of the negative pressure suction nozzle to be in top contact with the placing plate.

Based on the problem, this application adopts following mode to solve, has set for the procedure through the singlechip to control the positive, reverse rotation mode and the operating time of motor, and the time of corotation and reversal is fixed at every turn, but the number of turns of corotation will be less a ration than the number of turns of reversal, and this ration is decided by the interval of two adjacent boards of placing. Embodied on the drive belt: the positive linear displacement of the transmission belt is less than the reverse linear displacement by one displacement, and the displacement is the distance between two adjacent placing plates; is embodied on the negative pressure suction nozzle: when the distance between two adjacent placing plates is A, the motor rotates forwards for the first time, the negative pressure suction nozzle moves to the place where the plate is placed at the bottommost part of the placing frame, for example, the forward movement displacement of the negative pressure suction nozzle is 10A at the moment, after the motor rotates backwards, the negative pressure suction nozzle moves backwards and exceeds the initial position by the length of A, and the reverse movement of the negative pressure suction nozzle is 11A at the moment; corotation of motor second time, negative pressure suction nozzle forward move and be 10A, just in time remove to the bottommost place board department of placing above the board, and after the motor reversal, negative pressure suction nozzle continues to make reverse movement and crosses initial position length and be 2A, and negative pressure suction nozzle reverse movement is 11A at this moment, so operation repeatedly, can ensure: 1) the linear displacement of the forward rotation of the transmission belt is fixed, and the linear displacement of the forward movement at each time is the same, so that the displacement of the shifting plate at each time is the same; 2) each positive movement enables the negative pressure suction nozzle to reach the correct position to place the tobacco leaves on the placing plate from top to bottom in sequence. Of course, how to realize the transmission calculation between the transmission wheel and the belt pulley of the plate shifting mechanism needs to be calculated according to the radiuses of the transmission wheel, the sleeve, the indirect wheel and the belt pulley, and the requirement that the ratio of the product of the radiuses of the transmission wheel and the indirect wheel and the product of the radiuses of the sleeve and the belt pulley = the ratio of the positive displacement of the negative pressure suction nozzle to the distance between two adjacent placing plates can be met.

Meanwhile, when the motor rotates forwards, a driving wheel of the motor drives a driving wheel to rotate through a belt or a chain, the driving wheel further drives a first driven wheel to rotate forwards through a shaft rod, the first driven wheel is matched with a first tension wheel to enable the first belt to rotate clockwise, meanwhile, a third driven wheel drives a third tension wheel and a smoke inlet driving gear to rotate through a third belt, and further enables a smoke inlet driven gear to drive a second tension wheel and a second driven wheel to rotate, the rotating directions of the first belt and the second belt are opposite due to meshing of gears, so that the first belt and the second belt can support corresponding support rods to move upwards through silica gel support plates on belt bodies of the belts, the support rods are arranged by being attached to guide plates, the guide plates are inclined plates, so that the process that the support rods move upwards is also a process that the two support rods move oppositely, and further support wheels on the two support rods can move towards a tobacco leaf main vein relative to the rolling of, to better hold the tobacco leaves above. When the motor rotates reversely, the processes are performed reversely, the supporting wheels on the two support rods can roll relative to the tobacco leaves and move away from the main veins of the tobacco leaves, and meanwhile, the tobacco leaves supported above the supporting wheels integrally descend, so that the tobacco leaves at the lowest part can be smoothly sucked by the negative pressure suction nozzle.

It should be noted that, although the transmission of the tobacco feeding device is also based on the transmission wheel, the transmission of the tobacco feeding device should not be affected by the number of forward turns of the transmission wheel being smaller than the number of reverse turns, otherwise the whole displacement of the tobacco leaves driven by the supporting rod is downward. In order to solve the problem, this application has set up the limiting plate, moves down and reach the limiting plate back when the die-pin every time, and it can't be moving down, but first, the second belt still does the action of pulling down it, and the silica gel layer board takes place to deform at this moment can in order to cross the die-pin. But each time the forward rotation is finished, the supporting rod can be kept to move to the top of the guide plate. Finally explained is: when the tobacco leaves are reversely rotated, the support rod drives the tobacco leaves to descend, so that the tobacco leaves can be conveniently sucked by the reversely-moved negative pressure suction nozzle; when the tobacco leaves are positively rotated, the tobacco leaves are driven to rise by the supporting rod because the negative pressure suction nozzle sucks the tobacco leaves.

More specifically, the corresponding displacement amount and the forward and reverse rotation speeds and time periods of the motor must be calculated according to the actual size of the mechanism.

Finally, it should be noted that, although the present application does not describe in detail how the corresponding mechanisms such as the driving wheels, the motors, the placing racks, etc. are supported, as a common knowledge, the corresponding wheels may be connected to the chassis through the shaft rods to realize the support, and the corresponding motors may be connected to the chassis through the base, the plate bodies through the support rods, etc., because the actions in the present application only relate to the vertical plane, the corresponding support connection mechanisms do not affect the corresponding actions at all.

Compared with the prior art, the invention has the following advantages:

1) this application design benefit through mutual transmission and the cooperation of a plurality of mechanisms, can only accomplish absorption, transmission and arrange in proper order under the effect of a power supply, for the many power unit among the prior art, has practiced thrift the manufacturing cost and the maintenance cost of machinery by a wide margin.

2) This application structure is comparatively simple, and convenient operation for manual pole of plaiting article among the prior art, work efficiency promotes by a wide margin, presss from both sides and plaits these three kinds of modes of pole for cigarette frame, cigarette moreover, can regular tobacco leaf's interval completely, improves the inside air current unobstructed nature of baking house after the dress cigarette, improves the tobacco leaf and toasts modulation quality.
