Angle is 22~28 degree, and it is 32~38 degree that annular guide groove 32, which is spaced corresponding central angle,；The upper end of folding lid bottom sheet 9 is provided with
The symmetrical circular guide groove 33 of the heart, the central angle of circular guide groove 33 is 30~45 degree, and the depth of circular guide groove 33 is more than opening
Close the thickness of piece 8.The uniform multiple folding lid bottom sheet screws 31 in the edge of folding lid bottom sheet 9, the edge of folding lid upper piece 10 is uniformly multiple
Folding lid upper piece screw 34, folding lid bottom sheet 9 is equal with the screwhole diameter of folding lid upper piece 10, and position is corresponding.Under folding lid
Piece 9 is fixedly connected with folding lid upper piece 10 by fixing bolt 23；The a line of long strip through hole 35 and annular are oriented to when fixed
The a line alignment of groove 32, assembling the folding cap assemblies of completion makes folding piece 8 after by long strip through hole 35 in circular guide groove
Rotated in 33, folding piece 8 drives folding cap assemblies to rotate or lift folding cap assemblies.
Folding lid executing agency includes folding piece 8, mobile bar 12, fix bar 13, telescopic cylinder 18, push-and-pull cylinder 20, gas
Dynamic motor 24, overhead traveling crane 15, guide rail 14,3rd sensor 17, the 4th sensor 19, guide rail beam 21, the first travel switch 16, the
Two travel switches 22, feather key 36, guide groove 37, guide rail 14 are fixed on rail brackets, and guide rail beam 21 is arranged on guide rail branch
One end of frame, the first travel switch 16 and the second travel switch 22 are separately fixed at the both ends of guide rail 14, and overhead traveling crane 15 is in the first row
Moved between the travel switches 22 of Cheng Kaiguan 16 and second, the first travel switch 16 and the second travel switch 22 are used for detecting overhead traveling crane 15
Whether relevant position is driven to.Push-and-pull cylinder 20 is fixedly mounted on the madial wall middle part of guide rail beam 21, and push-and-pull cylinder 20 is stretched
Contracting bar is connected with the bearing plate side on overhead traveling crane 15；Push-and-pull cylinder 20 drives overhead traveling crane 15 to be moved along guide rail 14.
Telescopic cylinder 18 is fixed on the centre of bearing plate on overhead traveling crane 15, and the one end of fix bar 13 is fixed on the load-bearing of overhead traveling crane 15
Centre below plate, and be co-axially mounted with telescopic cylinder 18, the piston rod of telescopic cylinder 18 passes through bearing plate and fix bar
Lumen pore on 13 is connected with the one end of mobile bar 12, and the one end of air motor 24 and the other end of mobile bar 12 are connected, folding piece 8 and gas
The rotating shaft of dynamic motor 24 is connected, and air motor 24 realizes the rotation of folding piece 8.There are two symmetrical feather keys in mobile bar 12
36, there is on the internal chamber wall of fix bar 13 guide groove 37 coordinated with feather key 36 to play guide effect, while in the band of air motor 24
Dynamic folding piece 8 bears moment of torsion when rotating, and prevents the rotation of the piston rod of telescopic cylinder 18；Drive of the mobile bar 12 in telescopic cylinder 18
It is lower to be slided along the inner chamber guide groove 37 of fix bar 13, lifting and putting down for folding cap assemblies is realized by folding piece 8.3rd sensor
17 and the 4th sensor 19 be separately mounted on the cylinder body of telescopic cylinder 18, for judging that extending and retracting for telescopic cylinder 18 be
It is no in place.The sensor 19 of 3rd sensor 17 and the 4th is magnetic switch.
Various materials are conveyed into roller 2, convey a certain amount of rear stopping conveying, now the pushing away in push-and-pull cylinder 20 of overhead traveling crane 15
Moved under dynamic along guide rail 14；Because folding piece 8 is stuck in the circular guide groove 33 of folding cap assemblies, folding cap assemblies are also with day
Car 15 moves.When push-and-pull cylinder 20 reaches its end of travel, overhead traveling crane 15 moves into place, while overhead traveling crane 15 touches the first stroke
Switch 16 is simultaneously turned on, and now telescopic cylinder 18 promotes mobile bar 12 to move down；When telescopic cylinder 18 is moved to stroke end
During end, 3rd sensor 17 is triggered, and the upper surface of the lower surface of folding lid bottom sheet 9 just with roller 2 is in contact, sealing ring quilt
It is compressed between contact surface and forms pretightning force；After 3rd sensor 17 is triggered, air motor 24 drives the dextrorotation of folding piece 8
Turn, after 30~45 degree of rotation, folding piece 8 drives the rotation of folding cap assemblies.When on annular guide groove 32 and annular prerotation vane 29
After bump contact, the pressure in gas circuit is begun to ramp up, and when pressure reaches setting value, air motor 24 fails, and stretches simultaneously
Contracting cylinder 18 drives folding piece 8 to move upward out folding cap assemblies, and now the first cylinder 6 and the second cylinder 26 drive claw retraction,
4th sensor 19 and second sensor 5 are triggered, and closing lid action is completed.
After the completion of closing lid action, roller air motor 7 drives roller 2 to be rotated, and material is mixed；When arrival is set
During fixed incorporation time, roller air motor 7 reduces speed now, after a period of time of slowing down, when roller detection switch 11 is connected, and roller
Air motor 7 stops the rotation, and now the upper surface of roller 2 is just upward.First cylinder 6 and the second cylinder 26 promote the first claw
3 and second claw 27 carry out righting to roller 2, when the first cylinder 6 and the second cylinder 26 arrival end of travel, righting has acted
Into, while first sensor 4 is connected, mix action is completed.
After the completion of mix action, folding piece 8 moves down in the presence of telescopic cylinder 18, when telescopic cylinder 18 is moved to
During end of travel, 3rd sensor 17 is triggered, and now face of the lower surface of folding piece 8 just with circular guide groove 33 contacts；
Air motor 24 drives the rotate counterclockwise of folding piece 8, and after 30~45 degree of rotation, folding piece 8 drives folding cap assemblies to rotate；Work as ring
After bump contact on shape guide groove 32 and annular prerotation vane 29, the pressure in gas circuit is begun to ramp up, when pressure reaches setting value
When, air motor 24 stops the rotation；Telescopic cylinder 18 lifts folding cap assemblies by folding piece 8, when telescopic cylinder 18 retracts to
During initial position, the 4th sensor 19 is triggered；Push-and-pull cylinder 20 is bounced back, and overhead traveling crane 15 moves along guide rail 14, and push-and-pull cylinder 20 is returned
When being reduced to initial position, the second travel switch 22 is triggered, and action of uncapping is completed.
Uncap after the completion of action, cylinder drives claw to bounce back, and after the completion of retraction, second sensor 5 is triggered, and roller is pneumatic
Motor 7 starts to rotate, and photoelectric encoder 25 detects the anglec of rotation of roller 2, when roller 2 rotates to the angle of setting, roller gas
Dynamic motor 7 stops the rotation, and roller 2 starts discharging；When discharge time reaches setting value, roller air motor 7 starts to rotate, photoelectricity
Encoder 25 detects the anglec of rotation of roller, and when roller rotates to the angle of setting, roller air motor 7 stops the rotation, roller 2
Upper surface just upward, then claw carries out righting to roller 2, and now discharging action is completed.
Automatic open-close lid arrangement is constantly completed charging-closing lid-mix-and uncapped the action of-discharging-loading cycle, realizes automatic
Mixed material operation.
