In the present embodiment, by passively into the analysis of 16 rotation speed of silk wheel, accurately controlling the silk material amount of feeding to reach
Purpose increases the reliability of double nozzle component printings.
Another embodiment provided according to the present invention, as shown in fig. 7, a kind of control method of double nozzle components,
S1, when controller is resolved to the control signal of user, controller according to the control signal to commutation component hair
Send corresponding commutation signal.
When S21, the commutation component receive the first commutation signal, the controller controls pre- into silk component 40 to first
Set direction sliding, it is described into silk component 40 close to the movable spray head 30.
S22, commutation block 13 press reversing column 32.
S23, movable spray head 30 are moved to the direction far from printhead substrate 10.
When the component that commutates receives the first commutation signal, controller can be controlled into silk component 40 to movable spray head 30
Direction sliding during sliding, drives since commutation block 13 is arranged in on the sliding assembly of silk component 40, commutate block
13 can also follow sliding assembly to be slid, and commutation block 13 can move downward, and press down on reversing column 32；Movable spray head
30 i.e. movable printhead substrate 10, movable spray head 30 can be located at the downside of stationary nozzle 20, until sliding into silk component 40
It is sensed by location sensitive component 80.
When S24, the commutation component receive the second commutation signal, the controller controls pre- into silk component 40 to second
Set direction sliding, and close to the stationary nozzle 20.
When the component that commutates receives the second commutation signal, controller can be controlled into silk component 40 to stationary nozzle 20
Direction sliding, is sensed until sliding into silk component 40 by location sensitive component 80.
Preferably, S25, commutation block 13 unclamp reversing column 32.
Preferably, S26, movable spray head 30 are moved to the direction close to printhead substrate 10.
When the component that commutates slides from the position of sliding spray head to the position of stationary nozzle 20, pressed since reversing column 32 is in
The state of pressure, therefore, controller can be controlled to be slid into silk component 40 to the direction of stationary nozzle 20, during sliding, is changed
It can be moved downward to block 13, reversing column 32 is released, and movable spray head 30 resets, and is in the upper end of stationary nozzle 20.
S3, when location sensitive component 80 sense it is described into silk component 40 when, the controller control is described into silk component
40 feed silk material into the stationary nozzle 20 or movable spray head 30.
Specifically, in conjunction with shown in Fig. 1 to Fig. 7, user can first be powered on double nozzle components by controlling box, reselection
The spray head needed, i.e. stationary nozzle 20 or movable spray head 30, after user's selection, controller can be resolved to the control of user
Signal, and formed control signal for commutation signal, and commutation signal is sent to commutation component, i.e., controller can be to changing
The first commutation signal or the second commutation signal are sent to component.
When the component that commutates receives the first commutation signal, reversing motor 72 controls its output end and rotates along pointer, connection
It is also rotated clockwise in the tumbler gear 73 of 72 output end of reversing motor, and the rack gear 71 engaged with tumbler gear 73 can be to the left
Side is mobile, i.e., moves to the direction close to movable spray head 30.
In the motion process of rack gear 71 to the left, rack gear 71 is able to drive the side slip to the left of the sliding block 62 on the downside of it, and
Since commutation block 13 can be arranged on sliding block 62, commutation block 13 can also follow the side slip to the left of sliding block 62, in commutation block 13
In slipping to the left, the spacing to commutate between block 13 and the reversing column 32 or commutation head 33 of downside is gradually reduced, until
Commutation block 13 is connected on commutation head 33, and commutation block 13 can continue to side slip to the left, and therefore, commutation block 13 also can be continuous
Commutation head 33 is pressed down on, the elastic force of spring 31 is then overcome, movable spray head 30 is driven to move downward.
Until the location sensitive component 80 of end can sense rack gear 71 or sliding block when sliding block 62 slides onto close to end
62, and shown to have moved into silk component 40 with this close to one end of movable spray head 30, it actively can be close to quilt into silk wheel 42
It moves into silk wheel 16, and actively into the silk wheel 42 and passively diameter into the gap between silk wheel 16 already less than trunnion 15, works as user
When by silk material out of upside merging trunnion 15, silk material can be clamped in actively into silk wheel 42 and passively between silk wheel 16.
Controller can control into silk component 40 work, due to silk material according to be clamped at actively into silk wheel 42 with passively into
Between silk wheel 16, therefore, after actively being rotated into silk wheel 42, due to active between silk wheel 42 and silk material there are frictional force, because
This silk material can be fed to downside, and there is also frictional force due to silk material and passively between silk wheel 16, passively into silk wheel
16 can also follow and be rotated, and passively into the velocity of rotation of silk wheel 16 and actively into the velocity of rotation of silk wheel 42 always.
During silk material feeding, passive feedback component 50 can be got passively into the velocity of rotation of silk wheel 16, and
Velocity of rotation is sent to controller, controller can get the current feed speed of silk material and be analyzed.
When the feed speed that controller analyzes silk material is consistently less than or is higher than pre-set velocity, i.e. the current feeding of silk material
Amount is consistently less than or is higher than the preset amount of feeding, therefore, in double nozzle components there may be deficient feeding, plug wire or cross feeding can
Can, controller can control its warning device and alarm, to remind operator to carry out malfunction elimination.
When control its feed speed for analyzing silk material it is excessive or too small when, also can be by control actively into silk wheel 42
Revolving speed realizes the change of silk material feed speed.
When user needs to work using stationary nozzle 20, user can select stationary nozzle by operation control box
20, commutation component is ready to receive, and to the second commutation signal, the rotation of its output end reverse finger can be controlled by controlling motor, be connected to and changed
The also rotation counterclockwise of tumbler gear 73 to 72 output end of motor, and the rack gear 71 engaged with tumbler gear 73 can be to the right
It is mobile, i.e., it is moved to the direction close to stationary nozzle 20.
In the motion process of rack gear 71 to the right, rack gear 71 is able to drive the side slip to the right of the sliding block 62 on the downside of it, and
Since commutation block 13 can be arranged on sliding block 62, commutation block 13 can also follow the side slip to the right of sliding block 62, in commutation block 13
In slipping to the right, commutation block 13 can be gradually lifted up, and spring 31 can be gradually recovered elastic deformation, movable to spray
First 30 can move upwards, until movable spray head 30 can be located at stationary nozzle 20 when commutation block 13 is separated with commutation head 33
Upside realizes the reset of movable spray head 30.
When sliding block 62 slides onto close to the end of 20 one end of stationary nozzle, the location sensitive component 80 of end can be sensed
Rack gear 71 or sliding block 62, and show to be had moved into silk component 40 close to one end of stationary nozzle 20, actively into silk wheel with this
42 can approach passively into silk wheel 16, and actively into silk wheel 42 and passively into the gap between silk wheel 16 already less than trunnion 15
Diameter, when silk material is placed in trunnion 15 by user from upside, silk material can be clamped in actively into silk wheel 42 and passively into silk wheel
Between 16.
Therefore, silk material can be controlled again into silk component 40 to feed down out of trunnion 15.
