Summary of the invention
In order to solve problems of the prior art, the utility model proposes one can accurately adjust Save to the machine supplying powder of powder speed, there is quick, accurate, stable feature.
In order to achieve the above object, this utility model be the technical scheme is that
A kind of can accurately regulate to the machine supplying powder of powder speed, including electric motor I 1, at motor I1 axle head installs decelerator I2, and decelerator I2 output shaft is by shaft coupling I3 and stirring rod 9 Being connected, stirring rod 9 is placed in powder cabin 8, and powder cabin 8 is by suspension arrangement 6 and LOAD CELLS 7 hang over the mount 10, and the top cover of powder cabin 8 is disposed with powder input port 4, and powder cabin 8 bottom is fallen It is connected to powder drum 15, to powder drum by what converting interface was arranged with lower horizontal at the reducing of taper 15 internally installed have to powder spiral 16, to the axle head of powder spiral 16 by shaft coupling II 14 and Decelerator II 13 is connected with motor II 12, is provided with out away from one end of motor to powder drum 15 Powder mouth 17.
Described powder cabin 8 surrounding is provided with a suspension arrangement 6 every 90 ° of angles, at support 10 Relevant position LOAD CELLS 7 is installed, powder cabin 8 is fallen in biography of weighing by suspension arrangement 6 On sensor 7, the signal output of LOAD CELLS 7 is connected to microcomputer controller 11.
Described is communicated with powder cabin 8 top by balance to powder drum 15 communicating pipe 5.
Described motor II 12 uses adjustable speed motor.
Compared to the prior art, this utility model has the advantage that
1, by arranging LOAD CELLS and microcomputer controller, solving tradition machine supplying powder needs Repeatedly to demarcate to the problem of powder speed so that machine supplying powder can the most accurately be adjusted to powder speed Joint.Because LOAD CELLS measures the powder amount data in powder cabin in real time, pass to microcomputerized control Device, after microcomputer controller is obtained in real time to powder speed by computing, and setting value (expected value) Comparing, control to powder axis drive motor rotation speed change, progressively feedback regulation makes to powder speed steady It is scheduled on setting value, thus realizes accurately regulating to powder speed.
2, by arranging LOAD CELLS, powder amount in feed bin can the most accurately be measured.
3, by arranging balance communicating pipe 5, tradition machine supplying powder is solved to meal outlet pressure wave The problem of dynamic bad adaptability, the two internal pressure of balance so that be not under pressure ripple to powder speed Dynamic impact, can realize machine supplying powder steady and continuous to powder.
4, the motor II 12 slowed down by adjustable speed, so that powder-feeding amount is according to demand Carry out step-less adjustment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is partial enlarged drawing at the suspension in Fig. 1.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, including the electric motor I 1 for agitating device offer power, for increasing Motor torque, installs decelerator I2 at electric motor I 1 axle head, and decelerator I2 output shaft passes through Shaft coupling I3 is connected with stirring rod 9, and stirring rod 9 is placed in powder cabin 8, and powder cabin 8 top is Cylinder, bottom is inverted cone, is used for storing a certain amount of powder, and powder cabin top cover is with powder cabin originally Body passes through Flange joint, and is provided with silica gel sealing packing ring, maintains closed environment in storehouse, powder cabin It is disposed with powder input port 4 on the top cover of 8, is used in powder cabin, add powder.Powder cabin 8 bottom inverted cone Reducing at by being connected to powder drum 15, in powder drum 15 of arranging with lower horizontal of converting interface Portion is provided with to powder spiral 16, is used for carrying powder, passes through shaft coupling to the axle head of powder spiral 16 Device II 14 and decelerator II 13 are connected with motor II 12, and motor II 12 is adjustable speed motor, For providing driving force, decelerator II 13 to be used for increasing motor output torque to powder spiral 16.
