Description

Technical Field

[0001] The invention relates to the technical field of mixers, in particular to a horizontal shaftless mixer. Background Art

[0002] At present, in horizontal drum mixers, powders are lifted along the inner wall of the drum, or mixed by auxiliary stirring blades of the equipment accessories. After being lifted to a certain height, the powders fall along the surface of the powders to achieve mixing, that is, the radial powder convection of the drum is relatively large; the existing horizontal mixers have a much lower axial mixing speed than the radial mixing speed, so the mixing takes a long time and cannot meet the needs of mass production;

[0003] In the existing powder mixing, there is a situation where the powder agglomerates due to moisture or friction between different powder surfaces. The agglomerated powder not only blocks the mixer, but also affects the quality of powder mixing and affects subsequent production. Summary of the invention

[0004] The object of the present invention is to provide a horizontal shaftless mixer to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a horizontal shaftless mixer comprises a base frame, a first servo motor, a coupling, a mixing mechanism, a second servo motor and a discharging mechanism, the base frame is fixedly connected to the first servo motor, the output end of the first servo motor is transmission-connected to the coupling, the coupling is transmission-connected to the mixing mechanism, the mixing mechanism is rotationally connected to the base frame, the second servo motor and the discharging mechanism are both fixedly connected to the mixing mechanism, and the output end of the second servo motor is transmission-connected to the mixing mechanism.

[0006] This mixer is used to mix different powders together to make them uniform. The first servo motor outputs torque, which is transmitted to the mixing mechanism through the coupling. The mixing mechanism rotates to detect the mixing condition of the powders and whether powder agglomeration is caused by moisture and other factors. The second servo motor outputs torque and feeds it back to the internal mechanism for adjustment to break up the agglomerates. The completely mixed powder is output by the discharging mechanism, which can control the single discharge amount of the powder.

[0007] Furthermore, the mixing mechanism includes an outer cylinder, an opening and closing plate, outer screw blades, a base, inner screw blades, and a detection mechanism. The outer cylinder is provided with a feed port, a discharge port and a side hole. The opening and closing plate is rotatably connected to the feed port. The feed port is arranged on a side of the outer cylinder close to the first servo motor, and the discharge port is arranged on a side of the outer cylinder away from the first servo motor. The discharge port is fixedly connected to the discharge mechanism. The detection mechanism is provided with a plurality of groups, and a plurality of groups of detection mechanisms are fixedly connected to the side holes. A plurality of groups of detection mechanisms are evenly distributed along the axis of the outer cylinder. The outer screw blades are fixedly connected to the outer cylinder, the base is transmission-connected to the output end of the second servo motor, and the inner screw blades are fixedly connected to the base.

[0008] Different powders are injected into the outer cylinder from the feed port, and the entire outer cylinder is driven to rotate around its axis through the coupling. The powder is driven by the outer screw blade to be lifted along the inner wall of the outer cylinder to mid-air and falls. The powders are continuously rising and falling, impacting and diffusing each other to achieve a uniformly mixed state. The second servo motor outputs torque to drive the inner screw blade to rotate. The speed of the inner screw blade is greater than that of the outer screw blade. When the speed direction of the inner screw blade is the same, the inner screw blade drives the powder falling from the outer screw blade to accelerate back to the bottom of the outer cylinder, accelerating the circulation of the powder and making the powder mixed faster and more uniform. A part of the powder that performs centrifugal motion along the outer cylinder enters the detection mechanism through the side hole. The detection mechanism detects the agglomeration of the powder and feeds it back to the second servo motor. When the powder is agglomerated, the second servo motor outputs reverse torque, and the rotation direction of the inner screw blade is opposite to that of the outer screw blade. The powder agglomerates falling from the outer screw blade are crushed by the gap between the inner and outer screw blades. The falling speed of the powder itself is in the opposite direction to that of the inner screw blade, and the agglomerates are impacted and broken by the inner screw blade.

[0009] Furthermore, the inner diameter of the outer screw blade contacts the outer diameter of the inner screw blade, the pitch of the outer screw blade is greater than the pitch of the inner screw blade, and the number of threads of the outer screw blade is less than the number of threads of the inner screw blade.

[0010] The inner diameter of the outer screw blade contacts the outer diameter of the inner screw blade, ensuring that when the inner screw blade rotates in the opposite direction, the agglomerated powder can be crushed by the gap between the inner and outer screw blades. The pitch of the outer screw blade is greater than that of the inner screw blade, the number of threads of the outer screw blade is less than that of the inner screw blade, and the number of threads of the inner screw blade is more than that of the outer screw blade, thereby improving the effect of accelerating the powder and impact-crushing the agglomerates of the powder.

[0011] Furthermore, the detection mechanism includes a tube shell, a mounting frame, a pressure mechanism, a first-stage impeller, a second-stage impeller, a third-stage impeller and a fourth-stage impeller. The tube shell is provided with a first material port and a second material port. The first material port is provided on a side of the tube shell close to the feed port, and the second material port is provided on a side of the tube shell away from the feed port. The mounting frame is fixedly connected to the tube shell, and the pressure mechanism is provided with four groups. The four groups of pressure mechanisms are all fixedly connected to the mounting frame. The first-stage impeller, the second-stage impeller, the third-stage impeller and the fourth-stage impeller are all rotatably connected to one group of pressure mechanisms.

[0012] The mixed powder enters the tube shell from the first material port along the side wall of the outer cylinder. When the powder is not agglomerated, the powder will rotate through the first-stage impeller, the second-stage impeller, the third-stage impeller, and the fourth-stage impeller, and then be discharged from the second material port back to the outer cylinder. When the powder is agglomerated, the powder will be stuck on the impeller. As the powder continues to enter and accumulate on the impeller, the pressure exceeds the spring limit value in the pressure mechanism, and the weight of the powder accumulated on the impeller is detected by the pressure mechanism.

[0013] Furthermore, the number of first-stage impeller blades is less than the number of second-stage impeller blades, the number of second-stage impeller blades is less than the number of third-stage impeller blades, and the number of third-stage impeller blades is less than the number of fourth-stage impeller blades.

[0014] The number of blades of the first-stage impeller, the second-stage impeller, the third-stage impeller and the fourth-stage impeller increases gradually. The size of the agglomerates allowed to pass through the second-stage impeller is smaller than that of the first-stage impeller. Similarly, the fourth-stage impeller cannot pass agglomerates. The size of the agglomerates and whether they exist can be determined by analyzing the electrical signals of the four groups of pressure mechanisms.

[0015] Furthermore, the pressure mechanism includes a sliding column, a spring seat and a length measuring motor. The sliding column is rotatably connected to the first-stage impeller, the second-stage impeller, the third-stage impeller and the fourth-stage impeller. The sliding column is fixedly connected to the spring seat. The length measuring motor is fixedly connected to the spring seat. The output end of the length measuring motor is slidably connected to the first-stage impeller, the second-stage impeller, the third-stage impeller and the fourth-stage impeller.

[0016] The powder drives the first-stage impeller to rotate and slides down from the gap between the first-stage impeller blades. When the volume of the agglomerated powder exceeds the gap between the first-stage impeller blades, the agglomerates will accumulate on the first-stage impeller. When the accumulated powder continues to accumulate, with the continuous entry of new powder, the impact load exceeds the elastic limit of the spring seat, and the first-stage impeller slides along the sliding column. The length measuring motor connected to the first-stage impeller is pushed and slides to identify the displacement and send an electrical signal. The first-stage impeller, second-stage impeller, third-stage impeller, and fourth-stage impeller have the same principle of identifying pressure as the pressure mechanism.

[0017] Furthermore, the discharging mechanism includes a shell, a third servo motor, a fourth servo motor, a material dividing mechanism, a feed pipe and a discharge pipe. The feed pipe is fixedly connected to the discharge port. The shell is provided with a feed port and a discharge port. The feed port is arranged on a side of the shell close to the discharge port, and the discharge port is arranged on a side of the shell away from the discharge port. The feed port is fixedly connected to the feed pipe, and the discharge port is fixedly connected to the discharge pipe. The third servo motor and the fourth servo motor are both fixedly connected to the shell. The output end of the third servo motor and the output end of the fourth servo motor are both transmission-connected to the material dividing mechanism. The feed pipe is provided with a first slope, and the slope surface of the first slope points to the shell. The discharge pipe is provided with a second slope, and the slope surface of the second slope faces back to the shell.

[0018] The powder evenly mixed in the outer cylinder enters the feed pipe from the discharge port, passes through the feed port along the first slope and falls into the dividing mechanism. The third servo motor outputs torque to the dividing mechanism, and the dividing mechanism rotates to drive the powder to the discharge port. The powder flows out through the second slope of the discharge pipe, and the fourth servo motor outputs torque to the dividing mechanism. The dividing mechanism adjusts the amount of powder output each time.

[0019] Furthermore, the material dividing mechanism includes a first transmission disk, a first dividing page, a second transmission disk and a second dividing page. The first transmission disk is transmission-connected to the output end of the third servo motor, the first dividing page is fixedly connected to the first transmission disk, the second transmission disk is transmission-connected to the output end of the fourth servo motor, the second dividing page is fixedly connected to the second transmission disk, and the second dividing page is slidably connected to the first transmission disk.

[0020] The powder on the first slope slides down between the first transmission disc, the first dividing page and the second dividing page. The third servo motor outputs torque to drive the first transmission disc to rotate and transfer the powder to the discharge port. The fourth servo motor drives the second transmission disc to rotate, adjusts the gap capacity between the first dividing page and the second dividing page, and adjusts the amount of powder falling in at the same flow rate, thereby regulating the discharge amount.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a mixing mechanism, different powders are injected into the outer cylinder from the feed port, and the entire outer cylinder is driven to rotate around its axis by the coupling, and the powder is driven by the outer screw blade to be lifted along the inner wall of the outer cylinder to fall into the air, and the powder is continuously raised and dropped to impact and diffuse with each other, so as to achieve a uniformly mixed state, and the second servo motor outputs a torque to drive the inner screw blade to rotate, and the rotation speed of the inner screw blade is greater than that of the outer screw blade. When the rotation speed direction of the inner screw blade is the same, the inner screw blade drives the powder falling from the outer screw blade to accelerate back to the bottom of the outer cylinder, accelerates the circulation of the powder, and makes the powder more uniformly mixed faster, and the powder agglomeration situation is detected and fed back to the second servo motor. When the powder is agglomerated, the second servo motor outputs a reverse torque, and the rotation direction of the inner screw blade is opposite to that of the outer screw blade. The powder agglomerates falling from the outer screw blade are crushed by the gap between the inner screw blade and the outer screw blade, and the falling speed of the powder itself is in the opposite direction to that of the inner screw blade, and the agglomerates are impacted and broken by the inner screw blade; the present invention designs a detection mechanism, along Part of the powder in the outer cylinder undergoing centrifugal motion enters the detection mechanism through the side hole, and the mixed powder enters the interior of the tube shell through the first material port along the side wall of the outer cylinder. When there is no agglomeration of the powder, the powder will rotate through the first-stage impeller, the second-stage impeller, the third-stage impeller, and the fourth-stage impeller, and then be discharged from the second material port back to the outer cylinder. When there is agglomeration of the powder, the volume of the agglomerated powder exceeds the gap between the blades of the first-stage impeller, and the agglomeration will accumulate on the first-stage impeller. When the accumulated powder continues to accumulate, with the continuous entry of new powder, the impact load exceeds the elastic limit of the spring seat, and the first-stage impeller slides along the sliding column, and the length measuring motor connected to the first-stage impeller is pushed to identify the displacement and send an electrical signal. The first-stage impeller, the second-stage impeller, the third-stage impeller, the fourth-stage impeller and the pressure mechanism have the same principle of identifying pressure. The present invention can evenly and fully mix different powders, detect the mixing condition of the powders, detect whether the powder agglomeration is caused by factors such as moisture, and by identifying and crushing the powder agglomeration, the powder amount of a single feed is regulated, thereby improving the quality and efficiency of powder mixing.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, the present invention provides a technical solution of a horizontal shaftless mixer: comprising a base frame 1, a first servo motor 2, a coupling 3, a mixing mechanism 4, a second servo motor 5 and a discharging mechanism 6, the base frame 1 is fixedly connected to the first servo motor 2, the output end of the first servo motor 2 is transmission-connected to the coupling 3, the coupling 3 is transmission-connected to the mixing mechanism 4, the mixing mechanism 4 is rotationally connected to the base frame 1, the second servo motor 5 and the discharging mechanism 6 are both fixedly connected to the mixing mechanism 4, and the output end of the second servo motor 5 is transmission-connected to the mixing mechanism 4.

[0032] The mixer is used to mix different powders together to make them uniform. The first servo motor 2 outputs torque, which is transmitted to the mixing mechanism 4 through the coupling 3. The mixing mechanism 4 rotates to detect the mixing condition of the powders and whether the powders are agglomerated due to moisture or other factors. The second servo motor 5 outputs torque and feeds it back to the internal mechanism for adjustment to break the agglomerates. The completely mixed powders are output by the discharging mechanism 6, which can control the single discharge amount of the powders.

[0033] like Figure 2 , Figure 3 As shown, the mixing mechanism 4 includes an outer cylinder 41, an opening and closing plate 42, an outer screw blade 43, a base 44, an inner screw blade 45, and a detection mechanism 46. The outer cylinder 41 is provided with a feed port 411, a discharge port 412 and a side hole 413. The opening and closing plate 42 is rotatably connected to the feed port 411. The feed port 411 is arranged on a side of the outer cylinder 41 close to the first servo motor 2, and the discharge port 412 is arranged on a side of the outer cylinder 41 away from the first servo motor 2. The discharge port 412 is fixedly connected to the discharge mechanism 6. The detection mechanism 46 is provided with a plurality of groups, and a plurality of groups of the detection mechanism 46 are fixedly connected to the side hole 413. The plurality of groups of the detection mechanism 46 are evenly distributed along the axis of the outer cylinder 41. The outer screw blade 43 is fixedly connected to the outer cylinder 41. The base 44 is transmission-connected to the output end of the second servo motor 5, and the inner screw blade 45 is fixedly connected to the base 44.

[0034] Different powders are injected into the outer cylinder 41 from the feed port 411, and the entire outer cylinder 41 is driven to rotate around its axis by the coupling 3. The powder is driven by the outer screw blade 43 to be lifted along the inner wall of the outer cylinder 41 to fall into the air. The powders are continuously raised and dropped, impacted and diffused with each other, and a uniform mixing state is achieved. The second servo motor 5 outputs a torque to drive the inner screw blade 45 to rotate. The speed of the inner screw blade 45 is greater than that of the outer screw blade 43. When the speed direction of the inner screw blade 45 is the same, the inner screw blade 45 drives the powders falling from the outer screw blade 43 to accelerate back to the bottom of the outer cylinder 41, thereby accelerating the circulation of the powders. The ring can make the powder mixed more quickly and evenly. A part of the powder that performs centrifugal motion along the outer cylinder 41 enters the detection mechanism 46 through the side hole 413. The detection mechanism 46 detects the agglomeration of the powder and feeds it back to the second servo motor 5. When the powder is agglomerated, the second servo motor 5 outputs a reverse torque. The rotation direction of the inner screw blade 45 is opposite to that of the outer screw blade 43. The powder agglomerates falling from the outer screw blade 43 are crushed by the gap between the inner screw blade 45 and the outer screw blade 43. The falling speed of the powder itself is in the opposite direction to that of the inner screw blade 45, and the agglomerates are impacted and broken by the inner screw blade 45.

[0035] like Figure 2 As shown, the inner diameter of the outer screw blade 43 contacts the outer diameter of the inner screw blade 45 , the pitch of the outer screw blade 43 is greater than the pitch of the inner screw blade 45 , and the number of threads of the outer screw blade 43 is less than the number of threads of the inner screw blade 45 .

[0036] The inner diameter of the outer screw blade 43 is in contact with the outer diameter of the inner screw blade 45 to ensure that when the inner screw blade 45 rotates in the opposite direction, the agglomerated powder can be crushed by the gap between the inner screw blade 45 and the outer screw blade 43. The pitch of the outer screw blade 43 is greater than the pitch of the inner screw blade 45, the number of threads of the outer screw blade 43 is less than the number of threads of the inner screw blade 45, and the number of threads of the inner screw blade 45 is more than that of the outer screw blade 43, thereby improving the effect of accelerating the powder and impacting and crushing the agglomerates of the powder.

[0037] like Figure 4 As shown, the detection mechanism 46 includes a tube shell 461, a mounting frame 462, a pressure mechanism 463, a first-stage impeller 464, a second-stage impeller 465, a third-stage impeller 466 and a fourth-stage impeller 467. The tube shell 461 is provided with a first material port 4611 and a second material port 4612. The first material port 4611 is provided on a side of the tube shell 461 close to the feed port 411, and the second material port 4612 is provided on a side of the tube shell 461 away from the feed port 411. The mounting frame 462 is fixedly connected to the tube shell 461. The pressure mechanism 463 is provided with four groups. The four groups of pressure mechanisms 463 are all fixedly connected to the mounting frame 462. The first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466 and the fourth-stage impeller 467 are all rotatably connected to a group of pressure mechanisms 463.

[0038] The mixed powder enters the tube shell 461 from the first material port 4611 along the side wall of the outer cylinder 41. When the powder is not agglomerated, the powder will rotate through the first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466, and the fourth-stage impeller 467, and then be discharged from the second material port 4612 back to the outer cylinder 41. When the powder is agglomerated, the powder will be stuck on the impeller. As the powder continues to enter and accumulate on the impeller, the pressure exceeds the spring limit value in the pressure mechanism 463, and the weight of the powder accumulated on the impeller is detected by the pressure mechanism 463.

[0039] like Figure 4 As shown, the number of blades of the first-stage impeller 464 is less than the number of blades of the second-stage impeller 465, the number of blades of the second-stage impeller 465 is less than the number of blades of the third-stage impeller 466, and the number of blades of the third-stage impeller 466 is less than the number of blades of the fourth-stage impeller 467.

[0040] The number of blades of the first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466 and the fourth-stage impeller 467 increases gradually. The second-stage impeller 465 allows a smaller size of agglomerates to pass through than the first-stage impeller 464. Similarly, the fourth-stage impeller 467 cannot allow agglomerates to pass through. The size of the agglomerates and whether they exist can be determined by analyzing the electrical signals of the four groups of pressure mechanisms 463.

[0041] like Figure 5As shown, the pressure mechanism 463 includes a sliding column 4631, a spring seat 4632 and a length measuring motor 4633. The sliding column 4631 is rotationally connected to the first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466 and the fourth-stage impeller 467. The sliding column 4631 is fixedly connected to the spring seat 4632. The length measuring motor 4633 is fixedly connected to the spring seat 4632. The output end of the length measuring motor 4633 is slidingly connected to the first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466 and the fourth-stage impeller 467.

[0042] The powder drives the first-stage impeller 464 to rotate and slides down from the gap between the blades of the first-stage impeller 464. When the volume of the agglomerated powder exceeds the gap between the blades of the first-stage impeller 464, the agglomerates will accumulate on the first-stage impeller 464. When the accumulated powder continues to accumulate, with the continuous entry of new powder, the impact load exceeds the elastic limit of the spring seat 4632, and the first-stage impeller 464 slides along the sliding column 4631. The length measuring motor 4633 connected to the first-stage impeller 464 is pushed and slidably connected to identify the displacement and send an electrical signal. The first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466, and the fourth-stage impeller 467 have the same pressure recognition principle as the pressure mechanism 463.

[0043] like Figure 6 , Figure 7 As shown, the discharging mechanism 6 includes a housing 61, a third servo motor 62, a fourth servo motor 63, a material dividing mechanism 64, a feeding pipe 65 and a feeding pipe 66, the feeding pipe 65 is fixedly connected to the discharging port 412, the housing 61 is provided with a feeding port 611 and a feeding port 612, the feeding port 611 is provided on a side of the housing 61 close to the discharging port 412, the feeding port 612 is provided on a side of the housing 61 away from the discharging port 412, the feeding port 611 and the feeding pipe 66 are fixedly connected to the discharging port 412, 5, the discharge port 612 is fixedly connected to the discharge pipe 66, the third servo motor 62 and the fourth servo motor 63 are fixedly connected to the housing 61, the output ends of the third servo motor 62 and the fourth servo motor 63 are transmission-connected to the material distribution mechanism 64, the feed pipe 65 is provided with a first slope 651, the slope surface of the first slope 651 points to the housing 61, and the discharge pipe 66 is provided with a second slope 661, the slope surface of the second slope 661 faces away from the housing 61.

[0044] The powder that has been evenly mixed in the outer cylinder 41 enters the feed pipe 65 from the discharge port 412, passes through the feed port 611 along the first slope 651 and falls into the dividing mechanism 64, the third servo motor 62 outputs torque to the dividing mechanism 64, the dividing mechanism 64 rotates to drive the powder to the discharge port 612, the powder flows out through the second slope 661 of the discharge pipe 66, and the fourth servo motor 63 outputs torque to the dividing mechanism 64, the dividing mechanism 64 adjusts the amount of powder output each time.

[0045] like Figure 7As shown, the material dividing mechanism 64 includes a first transmission disk 641, a first dividing page 642, a second transmission disk 643 and a second dividing page 644. The first transmission disk 641 is drivingly connected to the output end of the third servo motor 62, the first dividing page 642 is fixedly connected to the first transmission disk 641, the second transmission disk 643 is drivingly connected to the output end of the fourth servo motor 63, the second dividing page 644 is fixedly connected to the second transmission disk 643, and the second dividing page 644 is slidably connected to the first transmission disk 641.

[0046] The powder on the first slope 651 slides down between the first transmission disk 641, the first dividing page 642 and the second dividing page 644. The third servo motor 62 outputs torque to drive the first transmission disk 641 to rotate and transfer the powder to the discharge port 612. The fourth servo motor 63 drives the second transmission disk 643 to rotate, adjusts the gap capacity between the first dividing page 642 and the second dividing page 644, and adjusts the amount of powder falling under the same flow rate, thereby regulating the discharge amount.

[0047] Working principle of the present invention: The mixer is used to mix different powders together to achieve a uniform state. The first servo motor 2 drives the mixing mechanism 4 to rotate. Different powders are injected into the outer cylinder 41 from the feed port 411, and driven by the outer screw blade 43 to be lifted along the inner wall of the outer cylinder 41 to fall into the air. Through the continuous rise and fall of the powders, the powders impact and diffuse with each other to achieve a uniform mixing state. The second servo motor 5 outputs torque to drive the inner screw blade 45 to rotate. The speed of the inner screw blade 45 is greater than that of the outer screw blade 43. When the speed direction of the inner screw blade 45 is the same, the inner screw blade 43 is The powder falling from the outer screw blade 43 is driven to accelerate back to the bottom of the outer cylinder 41, accelerating the circulation of the powder and making the powder mixed more evenly. A part of the powder that makes centrifugal motion along the outer cylinder 41 enters the detection mechanism 46 through the side hole 413, and the mixed powder enters the interior of the tube shell 461 through the first material port 4611 along the side wall of the outer cylinder 41. When the powder does not have agglomeration, the powder will rotate through the first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466, and the fourth-stage impeller 467, and then be discharged from the second material port 4612 back to the outer cylinder 41. When the powder When agglomeration occurs, the volume of agglomerated powder exceeds the gap between the blades of the first-stage impeller 464, and the agglomerates are accumulated on the first-stage impeller 464. When the accumulated powder continues to accumulate, with the continuous inflow of new powder, the impact load exceeds the elastic limit of the spring seat 4632, and the first-stage impeller 464 slides along the sliding column 4631. The length measuring motor 4633 connected to the first-stage impeller 464 is pushed and slidably connected to recognize the displacement and send an electrical signal. The first-stage impeller 464, the second-stage impeller 465, the third-stage impeller 466, and the fourth-stage impeller 467 are connected to the pressure mechanism 463 to recognize the pressure principle. The detection mechanism 46 detects the agglomeration of the powder and feeds it back to the second servo motor 5. When the powder is agglomerated, the second servo motor 5 outputs a reverse torque, and the rotation direction of the inner screw blade 45 is opposite to that of the outer screw blade 43. The powder agglomerates falling from the outer screw blade 43 are crushed by the gap between the inner screw blade 45 and the outer screw blade 43. The falling speed of the powder itself is in the opposite direction to that of the inner screw blade 45, and the agglomerates are impacted and broken by the inner screw blade 45. The completely mixed powder is output by the discharging mechanism 6, and the discharging mechanism 6 can control the single discharge amount of the powder.
