The air bag 7 is fixedly adhered to one side of the inner wall of the recess 41. An electric push rod 8 is arranged above the box body 6, and the lower end of the electric push rod 8 extends into the box body 6 and is fixedly provided with a first magnet 9.
In the initial state, the electronic valve 13 is closed, air passes through the air guide slot 12 to drive the fan 5 to rotate, a small part of air enters the chamber 13 and is injected into the air bag 61 along the first hose 611, so that the air bag 61 is inflated. When the pointer 171 passes through the grating 172 for a predetermined number of times, the single chip microcomputer 18 controls the electric push rod 8 to extend, and controls the electronic valve 613 to open. The electric push rod 8 drives the first magnet 9 to descend to press the air bag 61, and the air in the air bag 61 is injected into the air bag 7 through the second hose 612. The airbag 7 is inflated to block the leakage orifice 42 of the recess 41. Thereby achieving the purpose of preventing air from passing through the partition plate 4.
The second magnet 15 is in sliding fit with the front face of the injection bin 1, and the second magnet 15 can slide up and down.

The plugging component comprises a string 16, a cloth piece 101 and a positioning piece 102, the cloth piece 101 is fixedly installed at the bottom of the nozzle 10, the cloth piece 101 surrounds the bottom of the nozzle 10, the positioning piece 102 is welded to the bottom of the nozzle 10, the positioning piece 102 is fixedly bonded to two ends of the cloth piece 101, the string 16 penetrates through the cloth piece 101, a channel for accommodating the string 16 is formed in the cloth piece 101, two ends of the string 16 penetrate through the positioning piece 102 and then are staggered mutually, and then the string 16 is fixedly bound to the bottom of the second magnet 15.
When the second magnet 15 slides upwards to pull the string 16, the loop formed by the cloth pieces 101 contracts until the inner walls of the cloth pieces 101 contact with each other, and the opening of the nozzle 10 is sealed. The cloth 101 is closed in an S-shaped direction to form a loop, and the string 16 penetrates into the cloth 101 from the center of the cloth 101. This arrangement facilitates the pulling of string 16 to retract sheet 101.
The inner side of the cloth 101 is provided with a spring 20, and as shown in fig. 4, the end of the spring 20 is fixedly adhered to the inner wall of the cloth 101. Spring 20 is at the same level as the string in sheet 101.
The grating 172 is composed of a light beam emitting module and a light beam receiving module, the light beam emitting module emits a light beam to the light beam receiving module, when the pointer 171 passes through the light beam receiving module, the light beam is blocked, at this time, a signal is transmitted to the single chip microcomputer 18, and the single chip microcomputer 18 counts the light beam blocking times.
A sliding rail 2 is arranged above the injection bin 1, and a sliding block 3 is welded at the top of the injection bin 1. The electric push rod 8 is welded with the slide block 3. The top of the sliding rail 2 is welded with a rack 21, the sliding block 3 is in sliding fit with the sliding rail 2, the top of the sliding block 3 is pivoted with a gear 31, the gear 31 is meshed with the rack 21, one side of the sliding block 3 is fixedly provided with a motor 32, and a transmission shaft of the motor 32 is welded with the gear 31. The motor 32 rotates to drive the gear 31 to rotate, so that the sliding block 3 moves on the sliding rail 2.
In the above-described known apparatus, the air belt 61 and the air bag 7 are detached after the powder auxiliary is injected once. The flat air belt 61 and air bag 7 are replaced with a new one, and a second injection is performed.
The working principle is as follows: in the initial state, the electric push rod 8 extends the magnet one 9 to be at the lowest point. The second magnet 15 is attracted by the force and the magnetic force to rise to the highest position. At this time, the string pulls the sheet 101 to contract, and the spring 20 is in a compressed state. The electronic valve 13 is closed and no air is present in the air pocket 61, so that the air bag 7 is in a flattened state.
Then, the powder aid is fed into the injection silo 1 through the feed pipe 19. After the filling, the electric push rod 8 contracts to drive the first magnet 9 to ascend, the distance between the first magnet 9 and the second magnet 15 is increased, and the attraction force of the magnets is gradually weakened, so that the second magnet 15 sinks under the action of gravity. After the second magnet 15 sinks, the string 16 is not pulled any more, and the spring 20 is unfolded to support the cloth piece. The nozzle 10 at the lower end of the injection bin 1 is unblocked.
Then, air is injected into the injection chamber 1 through the air pipe 11 and the air guide groove 13, and the powder auxiliary agent is pushed by the air to be sprayed out. The air enters the air guide groove 12 to drive the fan 5 to rotate. The fan 5 rotates the pointer 171 inside the meter 17. The pointer 171 passes over the grating 172 once per revolution. The single chip microcomputer 18 counts the number of times the pointer 171 passes the grating 172.
At the same time, a small portion of air enters the chamber 13, enters the air bag 61 along the first hose 611, so that the air bag 61 is inflated. When the pointer 171 passes through the grating 172 for a predetermined number of times, the single chip microcomputer 18 controls the electric push rod 8 to extend, and controls the electronic valve 613 to open. The electric push rod 8 drives the magnet I9 to descend to press the air bag 61, and air in the air bag 61 is injected into the air bag 7 through the hose II 612. The airbag 7 is inflated to block the leakage orifice 42 of the recess 41. Preventing further air delivery.
At this time, magnet one 9 descends to attract magnet two 15 to ascend, magnet two 15 ascends to pull string 16, and string 16 contracts cloth piece 101, so that cloth piece 101 seals nozzle 10.
In summary, in the device for conveying and metering the powder additive for the printing and dyeing industry, the fan 5 is driven by air to rotate, so that the pointer 7 rotates to pass through the grating 172, and the purpose of metering is achieved. The first magnet 9 is driven to descend by the electric push rod 8, and the first magnet 9 descends to press the air bag 61 and attract the second magnet 15 to ascend. So that the air in the air bag 61 enters the air bag 7 and the air bag 7 is inflated to block the leakage hole 42 of the isolation plate 4. At the same time, the second magnet 15 pulls the string 16 to contract the cloth piece 101, and the opening of the nozzle 10 is sealed. Therefore, the sealing effect is realized, and the effect of controlling the discharge capacity of the powder auxiliary agent is achieved. Replace traditional artifical measurement, improve work efficiency, further improved the measurement precision.
