With reference to Fig. 6, be arranged on first sensor 130 on the first connecting plate 111 for responding to the first depression bar 11, in the time that pump formula scraper head 10 is arranged on pump formula scraper head corollary apparatus 100, at various height, therefore the first depression bar can not be connected with the first contiguous block 113 annular groove 11a on the first contiguous block 113 and the first depression bar 11 on the first connecting plate.Now, the first driver 112 drives the first connecting plate 111 to move up and down, and in the time that the tail end of first sensor 130 and the first depression bar 11 moves in the induction range of inductor, first sensor 130 senses that the first depression bar 11, the first drivers stop action.Now, the first contiguous block 113 of the first connecting plate 111 and the annular groove 11a of the first depression bar are adjusted to sustained height.
Be arranged on the second sensor 140 on the second connecting plate 121 for responding to the second depression bar 12, in the time that pump formula scraper head 10 is arranged on pump formula scraper head corollary apparatus 100, at various height, therefore the second depression bar can not be connected with the second contiguous block 123 annular groove 12a on the second contiguous block 123 and the second depression bar 12 on the second connecting plate.Now, the second driver 122 drives the second connecting plate 121 to move up and down, and in the time that the tail end of the second sensor 140 and the second depression bar 12 moves in the induction range of inductor, the second sensor 140 senses that the second depression bar 12, the second drivers stop action.Now, the second contiguous block 123 of the second connecting plate 121 and the annular groove 12a of the second depression bar are adjusted to sustained height.
Pump formula scraper head corollary apparatus is provided with installation component and guidance set in order to installation pump formula scraper head 10.But in the time that first, second depression bar 11,12 is not connected with first, second contiguous block 113,123, pump formula scraper head 10 just cannot be arranged on installing plate 150.On the other hand, in the time that first, second depression bar 11,12 is connected with first, second contiguous block 113,123, pump formula scraper head 10 just can be arranged on installing plate 150.
Guiding driver element is used for making pump formula scraper head 10 to be closely connected with installing plate 150, so that pump formula scraper head 10 can stably be arranged on installing plate 150.The driver part 161 that can make stretching motion to installing plate 150 projected direction A1 with to installing plate 150 retraction direction A2 alternate reciprocating motion.When the first contiguous block 113 of the first connecting plate and the second contiguous block 123 of the second connecting plate and the annular groove 11a of the first depression bar and the annular groove 12a of the second depression bar be not during at sustained height, guiding parts 161 is to the projected direction A1 motion of installing plate 150.In the time that first sensor 130 and the second sensor 140 sense respectively first depression bar 11 the second depression bar 12, the first contiguous block 113 of the first connecting plate and the second contiguous block 123 of the second connecting plate be adjusted to annular groove 11a and second depression bar of the first depression bar on annular groove 12a at sustained height, now guiding parts 161 is to the retraction direction A2 motion of installing plate 150.
Magnetic fixed part 162 is made up of magnetic material, and adopt and can be made pump formula scraper head by the metal material of magnetic attraction, make magnetic fixed part 162 can utilize magnetic pull that pump formula scraper head 10 is pulled to installing plate 150, pump formula scraper head 10 is contacted with installing plate 150.Therefore,, when guiding parts 161 moves to installing plate retraction direction A2, pump formula scraper head 10 can be pulled to magnetic fixed part 162 by magnetic force.In the time that guiding driver element makes pump formula scraper head 10 with installing plate 150 close contact, the first depression bar 11 is connected with the first contiguous block 113, and the second depression bar 12 is connected with the second contiguous block 123.
Controller control is a series of by first sensor 130 and the second sensor 140 induced signal to the first depression bar 11 and the second depression bar 12 respectively, thereby stop the first driver 112 and the second driver 122 moves, and control guiding parts 161 and move to retraction direction A2.In addition the code signal that, controller can also send by the motor of the motor of the first driver 112 and the second driver 122 calculates the tin cream amount in pump formula scraper head 10.In the time that controller receives the code signal that the motor of the first driver 112 and the second driver 122 sends, controller can draw the position of the first depression bar 11 and the second depression bar 12, to determine volume and second cavity 14 volume second depression bar 12 current locations below of the first cavity 13 below the first depression bar 11 current locations, can calculate thus the tin cream surplus in pump formula scraper head 10.
Compared to first sensor 130, the three sensors 171, equally for responding to the first depression bar 11, difference is, the 3rd sensor 171 is installed in the junction of the first contiguous block 113 on the first depression bar 11 and the first connecting plate 111.Similarly, compared to the second sensor 140, the four-sensors 172, equally for responding to the second depression bar 12, difference is, four-sensor 172 is installed in the junction of the second contiguous block 123 on the second depression bar 12 and the second connecting plate 121.
With reference to Fig. 8, in the time that the first driver 112 drives the first depression bar 11 to move downward, the tin cream in pump formula scraper head 10 will be squeezed.Meanwhile, the second depression bar 12 correspondingly moves upward to guarantee the evenly ejection constantly of tin cream in pump formula scraper head 10 in proportion.But due to the viscosity of tin cream, in the time that the first depression bar 11 moves downward the pressure that tin cream is produced and passes to the second depression bar 12 by tin cream, will produce time delay, when therefore upwards promotion has the second depression bar 12 of constant weight, be prone to and be short of power.In the time that the first driver 112 drives the first depression bar 11 to move downward, need the second driver 122 to drive the second depression bar 12 to move upward.But, due to the time delay of tin cream transmission of pressure, will be difficult to control the movement degree that the second depression bar 12 moves upward.For example, if operate simultaneously, the first depression bar 11 moves downward, the second depression bar 12 moves upward, and due to the time delay that tin cream pressure transmits, will make the second depression bar 12 just move upward before pressure is not yet delivered to, thereby in pump formula scraper head 10, form negative pressure, make tin cream cannot stablize ejection.And adopt this pump formula scraper head corollary apparatus when operation, when the first depression bar 11 moves downward, in the time that the pressure of passing to the second depression bar 12 by tin cream is enough, the second depression bar 12 is subject to a thrust upwards and up moves, in the time that four-sensor 172 senses the second depression bar 12, thereby the position that the second driver 122 drives the second connecting plate 121 to move upward to expectation makes the second depression bar 12 can continue to move upward, so repeat.This suitably maintains the pressure energy in pump formula scraper head 10, thereby maintains equably the outside tin cream amount that is sprayed onto.
Similarly, when the second depression bar 12 moves downward, in the time that the pressure of passing to the first depression bar 11 by tin cream is enough, the first depression bar 11 is subject to a thrust upwards and up moves, in the time that the 3rd sensor 171 senses the first depression bar 11, thereby the position that the first driver 112 drives the first connecting plate 111 to move upward to expectation makes the first depression bar 11 can continue to move upward, so repeat.
The first support component 181 is installed on the first plate 111 and the second plate 121.The second support component 182 and the first connecting plate 111, the second connecting plates 121 connect, and are rotated and connect with the first support component 181 by a rotating shaft C1 parallel with pump formula scraper head moving direction.Pump formula scraper head moving direction described here refers to the direction that pump formula scraper head moves spray tin cream on steel mesh time.Due to the connecting mode of the first support component and the second support component, even if the steel mesh that tin cream sprays and ground not exclusively parallel have certain inclination angle with ground, but as long as the nozzle 18 of pump formula scraper head is parallel with steel mesh, tin cream just can normally spray.Therefore, the second support component 182 connecting with pump formula scraper head 10 by the first connecting plate 111, the second connecting plate 121 can swing with rotary connection of rotating shaft C1, guaranteed that the nozzle 18 of pump formula scraper head can be parallel to steel mesh in the time of printing always.
Damping 183 is arranged on the both sides of rotating shaft C1 on the first support component 181, while rotation for slowing down the second support component 182 and the first support component 181 produce collision belt give second vibrations that parts 182 bring.Guide rail 184 is arranged on the second support component 182 belows, plays guide effect in the time that pump formula scraper head 10 is installed.
