Described first conveyer belt is moved along clockwise direction with the second conveyer belt.
A kind of method using the pneumatic mortar machine with static weighing system, it comprises the following steps:A, start machine, PLC
Controller control conveyer belt convey the first raw material into high-speed stirred tank, simultaneously high-speed stirred tank agitating device start to rotate into
Row stirring;
B, when the first raw material weight that weighing sensor detects in high-speed stirred tank reaches the 80% ~ 95% of preset weight,
PLC controls high-speed stirred tank agitating device to stop operating, and pay-off continues feeding, until being fully achieved default weight
Amount, PLC controls conveyer device to stop conveying the first raw material, and high-speed stirred tank agitating device continues stirring;
C, PLC start the feeding work of second raw material, and high-speed stirred tank agitating device continues stirring simultaneously, and PLC is controlled
Device processed controls pay-off conveying second raw material, when the weight that weighing sensor detects the interpolation of second raw material reach default
Weight 80% ~ 95% when, PLC control high-speed stirred tank agitating device stop operating, pay-off continue transport second
Plant raw material, until it reaches preset weight, PLC stops conveying second raw material, the startup of high-speed stirred tank agitating device continues
Continuous stirring;
, until adding all raw materials, after PLC controls stirring certain time, slurry is from high-speed stirred tank for d, repeat step c
Enter storage tank;
E, repeat step a-d can achieve and be stirred continuously.
The positive effect of the present invention is:Pay-off and high-speed stirred tank agitating device is controlled to coordinate by PLC
Work, after reaching constant weight, high-speed stirred tank agitating device is automatically stopped work, and weighing precise degrees can be effectively ensured,
PLC can be automatically performed overall process measure control in strict accordance with slurry formulations simultaneously, gross weight error can control ±
Within 0.5%, can carry out working continuously controls and weighing precision does not reduce.

Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, the present invention includes the high-speed stirred tank that pay-off is connected with the discharging opening of pay-off
Storage tank 2 and Weighing system that 1 is connected with the discharging opening of high-speed stirred tank 1, described Weighing system include PLC,
It is arranged on weighing sensor and the motor being controlled by PLC, described motor and the high-speed stirred of high-speed stirred tank 1 bottom
Tank agitating device is connected, and described pay-off is connected with PLC.
Described pay-off include material bin 3 and be arranged on material bin 3 discharging opening on transfer passage 6, conveying
Be provided with conveyer belt 4 in passage 6, described conveyer belt 4 one end is connected with the discharging opening of material bin 3, described conveyer belt 4 another
End is connected with the charging aperture of described high-speed stirred tank 1.
Described material bin 3 includes the first material bin 301 and the second material bin 302, and described conveyer belt 4 includes the first conveying
Band 401 and the second conveyer belt 402, one end of described first conveyer belt 401 is connected with the discharging opening of the first material bin 301,
One end of described second conveyer belt 402 is connected with the discharging opening of the second material bin 402, described first conveyer belt 401 another
End is all connected with the feeding mouth of high-speed stirred tank 1 with the other end of the second conveyer belt 402.
Described first conveyer belt 401 and the second conveyer belt 402 are provided with for raw material is sent into high-speed stirred
The scraper plate 5 of tank 1, described first conveyer belt 401 and the second conveyer belt 402 will be former along moving clockwise as shown in Figure 1
Material is sent into, and raw material pushes high-speed stirred tank 1 by scraper plate 5 below conveyer belt 4, and after conveyer belt 4 stop motion, raw material is also immediately
Stop charging, charging precision is effectively ensured.
A kind of method using the pneumatic mortar machine with static weighing system, it comprises the following steps:A, start machine, PLC
Controller controls conveyer belt 3 to convey the first raw material into high-speed stirred tank 1, and high-speed stirred tank agitating device starts to rotate simultaneously
It is stirred.
B, when the first raw material weight that weighing sensor detects in high-speed stirred tank 1 reach preset weight 80% ~
When 95%, PLC controls high-speed stirred tank agitating device to stop operating, and pay-off continues feeding, until being fully achieved pre-
If weight, PLC controls conveyer device to stop conveying the first raw material, and high-speed stirred tank agitating device continues stirring.
C, PLC start the feeding work of second raw material, and high-speed stirred tank agitating device continues stirring simultaneously,
PLC controls pay-off conveying second raw material, when the weight that weighing sensor detects the interpolation of second raw material reaches
To preset weight 80% ~ 95% when, PLC control high-speed stirred tank agitating device stop operating, pay-off continue fortune
Send second raw material, until it reaches preset weight, PLC stops conveying second raw material, high-speed stirred tank agitating device
Start and continue stirring.
, until adding all raw materials, after PLC controls stirring certain time, slurry is from high-speed stirring for d, repeat step c
Mix tank 1 and enter storage tank 2.
E, repeat step a-d can achieve and be stirred continuously.
The present invention is controlled to whole feeding and whipping process using PLC, can be automatically performed feeding and
Whipping process, not only accurately, weighing sensor all carries out zero setting after each discharging it is ensured that every tank blanking meter for feeding
The accuracy of amount.
