Specifically, the plate body of the placing plate is in clearance fit with the through holes in the rack plate.
Specifically, the plane of the placing frame is vertical to the plane of three driving wheels of the tobacco leaf driving device.
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 motor and the exhaust fan are started, the negative pressure suction nozzle starts to move, a worker places tobacco leaves on the silica gel suction nozzle (the protruded veins on the tobacco leaf blades are on the back side, the front side is smooth and can better shield the silica gel suction nozzle, meanwhile, the length direction of the tobacco leaves and the transmission belt are required to be in a vertical state when the tobacco leaves are placed, the tobacco leaf handles and a second notch on the placing plate are arranged in the same direction), the exhaust fan extracts air in the bending pipe and the negative pressure suction nozzle, the negative pressure suction nozzle is shielded by the tobacco leaves when a channel on the bending pipe is shielded by the silica gel sheet, so that a negative pressure state can be kept in the bending pipe and the negative pressure suction nozzle, the negative pressure suction nozzle adsorbs the tobacco leaves, and the negative pressure suction nozzle drives the exhaust pipe to move along the channel on the bending pipe when moving along with the transmission belt, so that the inside of the negative pressure suction nozzle is always communicated with the inside of the bending pipe and keeps the negative pressure state, and the exhaust pipe can squeeze the silica gel sheet at the current position when moving, the tape blade in its previous position remains shielded from 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 placing plate body 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 inclined arrangement of the placing plate, 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 first 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 the adsorption position, the staff replaces the tobacco leaf, then negative pressure suction nozzle removes to the bottommost place board department of placing above the board, the operation is placed to repeated tobacco leaf, so circulation is reciprocal, all place the blade of new absorption on the board is placed to the correspondence at every turn, and every places the board and all drive its tobacco leaf removal of accepting for the tobacco leaf all keeps leaning on in its main arteries and veins and places board plate body department, and the petiole exposes to placing outside the board completely from second breach department. Then the staff stops motor work, prick the pole of pricking that the bottom is sharp from the second breach department of placing the board down, can be from last to passing the petiole of every tobacco leaf in order down, then upwards slightly lift and prick the pole, make the tobacco leaf with place the board separation, the gag lever post is pasted completely after losing blockking of tobacco leaf owner arteries and veins and is placed the board plate body, the tobacco leaf does not receive the blockking of top gag lever post again promptly, can continue to lift and prick the pole and drive all tobacco leaves and take out from the case, the tobacco leaf on so pricking the pole can be equidistant distribution, then prick the pole with the several and hang in order and lean on and accomplish the dress cigarette on the string roof beam of baking house.
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 not greatly influenced by the modulation quality after being punctured.
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 wheel at the joint of the horizontal section and the inclined section of the driving belt to rotate, and the driving wheel drives the other two driving wheels and the negative pressure suction nozzle to move through the transmission of the driving belt; meanwhile, the driving wheel at the joint of the vertical section and the inclined section of the driving belt drives the first driving rod to rotate positively, when the ratchet gear at the end part of the first driving rod rotates positively, the pawl abuts against the gear teeth of the ratchet gear, the ratchet gear 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 first 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 can contact the board roof of placing of the below on the rack, because the roof of placing the board with dial the board parallel, so work as when dialling the board and shift up and contact this roof of placing the board, make the roof drive place the board and move along corresponding through-hole, when dialling the board base and move to the roof topside, the roof top of placing the board touches the through-hole, the upwards displacement of placing the board reaches the terminal point promptly at this moment, dial the board and continue to move up the back, its and this roof separation of placing the board, should place the board and move along the through-hole and reset under the dead weight effect, dial the board of placing above the board contact simultaneously and make it shift up along the through-hole. 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.
It should be noted that the action of dialling the board depends on the first belt drive of connection, and the transmission of first belt is based on the indirect transmission of drive belt, if drive belt forward removal then first belt forward removal, drive belt reverse removal then first belt reverse removal, it is upper and lower removal specifically to the action of dialling the board. 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 first 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, the original position of the negative pressure suction nozzle is taken as a mark point, the positive movement amount of the transmission belt driving the negative pressure suction nozzle at each time is decreased, namely, the negative pressure suction nozzle moves forwards for the first time, the negative pressure suction nozzle moves to the bottommost placing plate from the original position, the negative pressure suction nozzle moves forwards for the second time after resetting, 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 first 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 for the second time of the motor, negative pressure suction nozzle forward move is 10A, just in time moves to the bottommost place board department of placing above the board, and after the motor reversal, negative pressure suction nozzle continues to make reverse direction movement and crosses initial position length and be 2A, and negative pressure suction nozzle reverse direction is 11A at this moment, so operation repeatedly, just 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.
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.

the end of the second transmission rod 52 is provided with an indirect wheel 57, and the indirect wheel 57 is in transmission connection with the sleeve 54 through an indirect belt 58 tensioned by the two.
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 motor and the exhaust fan are started, the negative pressure suction nozzle starts to move, a worker places tobacco leaves on the silica gel suction nozzle (the protruded veins on the tobacco leaves are on the back side, the front sides of the tobacco leaves are smooth and can better shield the silica gel suction nozzle, so the tobacco leaves are placed with the front sides facing downwards, meanwhile, the length direction of the tobacco leaves and the transmission belt are required to be in a vertical state when the tobacco leaves are placed, the petioles of the tobacco leaves and the second notches on the placing plate are arranged in the same direction), the exhaust fan extracts air in the bending pipe and the negative pressure suction nozzle, the negative pressure suction nozzle is shielded by the tobacco leaves when the channels on the bending pipe are shielded by the adhesive tape sheets, so the negative pressure state can be kept in the bending pipe and the negative pressure suction nozzle, the tobacco leaves are adsorbed by the negative pressure suction nozzle, and the negative pressure suction nozzle drives the exhaust pipe to move along the channels on the bending pipe when moving along with the negative pressure suction nozzle, the interior of the negative pressure suction nozzle is always communicated with the interior of the bending pipe and kept in the negative pressure state, meanwhile, the air 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 placing plate body 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 inclined arrangement of the placing plate, 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 continuously move upwards along with the first belt, and at the moment, the shifting plate moves upwards
With placing the board separation at present, it moves down along the through-hole to place the board at the dead weight effect, because the recess groove depth is only 1-2mm, this just makes the blade of tobacco leaf can arrange the recess in completely, and the main arteries and veins of tobacco leaf can expose outside the recess, so when placing the board with dial the board separation back and move down the reset in-process, the main arteries and veins of tobacco leaf can't pass the through-hole along with the plate body, make the main arteries and veins be extruded and paste the rack board plate body setting of leaning on at the through-hole under the effect of gag lever post, the tip of the main arteries and veins promptly the petiole department is in the second breach department and is exposed completely simultaneously.
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 the adsorption position, the staff replaces the tobacco leaf, then negative pressure suction nozzle removes to the bottommost place board department of placing above the board, the operation is placed to repeated tobacco leaf, so circulation is reciprocal, all place the blade of new absorption on the board is placed to the correspondence at every turn, and every places the board and all drive its tobacco leaf removal of accepting for the tobacco leaf all keeps leaning on in its main arteries and veins and places board plate body department, and the petiole exposes to placing outside the board completely from second breach department. Then the staff stops motor work, prick the pole of pricking that the bottom is sharp from the second breach department of placing the board down, can be from last to passing the petiole of every tobacco leaf in order down, then upwards slightly lift and prick the pole, make the tobacco leaf with place the board separation, the gag lever post is pasted completely after losing blockking of tobacco leaf owner arteries and veins and is placed the board plate body, the tobacco leaf does not receive the blockking of top gag lever post again promptly, can continue to lift and prick the pole and drive all tobacco leaves and take out from the case, the tobacco leaf on so pricking the pole can be equidistant distribution, then prick the pole with the several and hang in order and lean on and accomplish the dress cigarette on the string roof beam of baking house.
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 not greatly influenced by the modulation quality after being punctured.
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 transmission wheel at the joint of the horizontal section and the inclined section of the transmission belt to rotate, and the transmission wheel drives the other two transmission wheels and the negative pressure suction nozzle to move through the transmission of the transmission belt; meanwhile, the driving wheel at the joint of the vertical section and the inclined section of the driving belt drives the first driving rod to rotate positively, when the ratchet gear at the end part of the first driving rod rotates positively, the pawl abuts against the gear teeth of the ratchet gear, the ratchet gear 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 first 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-hole. 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.
It should be noted that the action of dialling the board depends on the first belt drive of connection, and the transmission of first belt is based on the indirect drive of drive belt, if the drive belt forward removes then first belt forward removal, drive belt reverse removal then first belt reverse removal, and the action that specifically dials the board is upper and lower removal. 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 first 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, the original position of the negative pressure suction nozzle is taken as a mark point, the positive movement amount of the transmission belt driving the negative pressure suction nozzle at each time is decreased, namely, the negative pressure suction nozzle moves forwards for the first time, the negative pressure suction nozzle moves to the bottommost placing plate from the original position, the negative pressure suction nozzle moves forwards for the second time after resetting, 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 first 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.
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.
