[0016] 2. The present invention arranges the iris assembly and further designs the opening and closing guide groove, so that when the top ring disk rotates relative to the bottom ring disk, the position of the gap between the opening and closing guide groove and the centripetal groove changes, causing the movable rod to move. When the movable rod moves from the centripetal end of the V-shaped groove to the eccentric end of the V-shaped groove, the movable rod moves from the centripetal end of the centripetal groove to the eccentric end of the centripetal groove, and the rotating plate and the sealing plate move accordingly. Under the interaction force of a plurality of sealing plates, the sealing plate rotates along the movable rod with the rotating plate, so that the iris assembly forms an open shape. Similarly, when the movable rod moves from the eccentric end of the V-shaped groove to the centripetal end of the V-shaped groove, the iris assembly forms a closed shape. The plurality of V-shaped grooves located above and the plurality of sealing plates located below are arranged. A plurality of V-shaped grooves are staggered so that the opening and closing time of the upper and lower iris assemblies are staggered, and any two adjacent V-shaped grooves are arranged to be connected by the arc groove, so that when the movable rod moves in the arc groove, the iris assembly is formed and maintained in a closed state, and the gap distance at both ends of the V-shaped groove is greater than or equal to the gap distance at both ends of the V-shaped groove opening, so that when the movable rod on one of the iris assemblies moves on the corresponding V-shaped groove to control the opening and closing state of the iris assembly, the movable rod on the other iris assembly must move in the corresponding arc groove and remain in a closed state. This arrangement enables the unidirectional rotation of the two top ring disks relative to the two bottom ring disks to control the opening and closing of the staggered time of the two iris assemblies.

[0017] 3. The present invention arranges the rotating mechanism and the powder adding mechanism so that the rotation of the slide rod can drive the limit ring block and the slide tube located above to rotate, so that the limit ring block located below rotates. Referring to the rotation principle of the top ring disk, it can be seen that the limit ring block cannot rotate in the forward direction relative to the rotating groove B, but can only rotate in the reverse direction relative to the rotating groove B. When the slide rod rotates in the forward direction, the limit ring block drives the connecting ring block to rotate through the limit column B, and the connecting ring block drives the top ring disk to rotate through the connecting rod to control the opening and closing of the iris assembly. At this time, the connecting ring block located above drives the sleeve to rotate, so that the rotating column drives the lifting guide block to rotate at the same speed as the transmission shaft, so that the lifting There is no relative rotation between the descending guide block and the lifting guide groove. When the slide rod rotates in the reverse direction, the top ring disk cannot rotate in the reverse direction, so the connecting ring block and the sleeve cannot rotate in the reverse direction. At this time, the state of the iris assembly remains unchanged, and the transmission shaft drives the lifting guide groove to rotate in the reverse direction, so that the lifting guide block moves in the lifting guide groove, causing the rotating column to drive the sleeve to move up and down, so that the upper connecting ring block is lifted and lowered, driving the entire connecting part and the upper iris assembly to lift and lower. The upper mounting ring block and mounting seat B are lifted and lowered along the slide groove with the slider, so that the size of the quantitative dosing cavity surrounded by the two iris assemblies and the pipeline assembly changes, thereby adjusting the powder dosage.

The powder conveying mechanism 6 of the invention is a prior art and will not be described in detail here.

[0021] In the embodiment of the present invention, the iris assembly 9 includes a top ring disk 91 and a bottom ring disk 93, the top ring disk 91 is rotatably connected to the pipeline assembly 8, the top ring disk 91 is connected to the output end of the rotating mechanism 4, the bottom end of the top ring disk 91 is an annular structure with equal spacing and a plurality of opening and closing guide grooves 92 are opened, and the two opening and closing guide grooves 92 are arranged alternately, the bottom ring disk 93 is fixedly connected to the pipeline assembly 8, the top end of the bottom ring disk 93 is an annular structure with equal spacing and a plurality of centripetal grooves 94 are opened, and a plurality of sealing plates 95 are provided in the gap between the top ring disk 91 and the bottom ring disk 93 relative to the plurality of centripetal grooves 94, and any two adjacent sealing plates 95 are movably connected, and the sealing plates 95 are of a trapezoidal structure, and the sealing plates 95 are eccentric. A rotating plate 96 is fixedly provided at the end, and a movable rod 97 is rotatably connected to the rotating plate 96. The top ends of several movable rods 97 are movably connected to the opening and closing guide grooves 92, and the bottom ends of several movable rods 97 are movably connected to several centripetal grooves 94 respectively; the opening and closing guide grooves 92 include several V-shaped grooves 921 arranged in a circular equidistant structure, and the number of several V-shaped grooves 921 is equal to the number of centripetal grooves 94. The several V-shaped grooves 921 located at the top and the several V-shaped grooves 921 located at the bottom are arranged alternately, and the centripetal ends of any two adjacent V-shaped grooves 921 are connected by arc grooves 922, and the gap distance at both ends of the V-shaped grooves 921 is greater than or equal to the gap distance at both ends of the opening of the V-shaped grooves 921. The present invention arranges the iris assembly 9 and further designs the opening and closing guide grooves 92, so that when the top ring disk 91 rotates relative to the bottom ring disk 93, the gap position between the opening and closing guide grooves 92 and the centripetal grooves 94 changes, causing the movable rod 97 to move. Figure 6It can be seen that when the movable rod 97 moves from the centripetal end of the V-shaped groove 921 to the eccentric end of the V-shaped groove 921, the movable rod 97 moves from the centripetal end of the centripetal groove 94 to the eccentric end of the centripetal groove 94, and the rotating plate 96 and the sealing plate 95 move accordingly. Under the interaction force of the sealing plates 95, the sealing plate 95 rotates along the movable rod 97 with the rotating plate 96, so that the iris assembly 9 forms the following Figure 7 Similarly, when the movable rod 97 moves from the eccentric end of the V-shaped groove 921 to the centripetal end of the V-shaped groove 921, the iris assembly 9 forms a Figure 8 In the closed form shown, a plurality of V-grooves 921 located at the top and a plurality of V-grooves 921 located at the bottom are arranged alternately, so that the opening and closing time of the upper and lower iris assemblies 9 are staggered, and the centripetal ends of any two adjacent V-grooves 921 are connected by an arc groove 922, so that when the movable rod 97 moves in the arc groove 922, the iris assembly 9 forms a closed form, and the gap distance at both ends of the V-groove 921 is greater than or equal to the gap distance at both ends of the opening of the V-groove 921, so that when the movable rod 97 on one of the iris assemblies 9 moves on the corresponding V-groove 921 to control the opening and closing state of the iris assembly 9, the movable rod 97 on the other iris assembly 9 must move in the corresponding arc groove 922 and remain in a closed form. This arrangement allows the unidirectional rotation of the two top ring disks 91 relative to the two bottom ring disks 93 to control the opening and closing of the two iris assemblies 9 at staggered times.

[0022] In the embodiment of the present invention, two slide grooves 21 are symmetrically arranged in the middle of the mounting vertical plate 2 , and two sliding blocks 22 are slidably mounted on the slide grooves 21 .

[0023] In an embodiment of the present invention, the storage mechanism 3 includes a storage barrel 31, the bottom end of the storage barrel 31 is a truncated cone structure, both ends of the storage barrel 31 are fixedly connected to the mounting plate 2 through a mounting seat A32, a cover plate 33 is fixedly provided at the top of the storage barrel 31, and a feed pipe 34 is connected to one side of the top of the cover plate 33.

[0024] In an embodiment of the present invention, the pipeline assembly 8 includes two mounting seats B81 arranged in an upper and lower structure, the two ends of the mounting seat B81 located at the top are fixedly connected to the two sliders 22 respectively, and the mounting seat B81 located at the bottom is fixedly connected to the mounting vertical plate 2. A mounting ring block 82 is fixedly provided on the mounting seat B81, and a rotation groove A83 is opened on the inner edge surface of the mounting ring block 82. Two top ring disks 91 are rotatably arranged on the top of the two rotation grooves A83 respectively, and two bottom ring disks 93 are fixedly arranged on the bottom of the two rotation grooves A83 respectively. Inner tubes 84 are fixedly provided at both ends of the mounting ring block 82 located at the top, and an outer tube 85 is sleeved on the inner tube 84. The outer tube 85 located at the top is connected to the bottom end of the storage barrel 31, and the bottom end of the outer tube 85 located at the bottom is connected to the top of the mounting ring block 82 located at the bottom, and the bottom end of the mounting ring block 82 located at the bottom is connected to the input end of the powder conveying mechanism 6. Through the above arrangement, the present invention makes the two mounting seats B81 and the two mounting ring blocks 82 unable to rotate, so that the rotating groove A83 cannot rotate, and the mounting ring block 82 and the mounting seat B81 located above can slide along the sliding groove 21 with the slider 22.

[0025] In an embodiment of the present invention, a plurality of triangular grooves A911 are provided on the surface of the top ring disk 91 in an annular equidistant structure, the gap between the triangular groove A911 and the rotating groove A83 constitutes a reverse limit cavity, a limit column A912 is provided in the reverse limit cavity, the limit column A912 is elastically connected to the deep part of the triangular groove A911 by a spring A913, a plurality of movable ball blocks A914 are movably provided at both ends of the limit column A912, the plurality of movable ball blocks A914 are evenly arranged, and the movable ball blocks A914 are movably connected to the triangular groove A911. The present invention further arranges the top ring disk 91 so that in a stationary state, the movable ball block A914 is located in the middle of the reverse limit cavity under the elastic force of the spring A913, so that when the top ring disk 91 rotates forward relative to the rotation groove A83, the limit column A912 moves toward the deep part of the triangular groove A911 under the friction resistance of the rotation groove A83, causing the spring A913 to be compressed, so that the limit column A912 has little effect on the forward rotation of the top ring disk 91, and ... and the movable ball block A914 is located in the middle of the reverse limit cavity under the elastic force of the spring A913, so that the movable ball block A914 is located in the middle of the reverse limit cavity when the top ring disk 91 rotates forward relative to the rotation groove A83, and the limit column A912 moves toward the deep part of the triangular groove A911 under the friction resistance of the rotation groove A83, causing the spring A913 to be compressed, and the movable ball block A914 is located in the middle of the reverse limit cavity when the top ring disk 91 rotates forward relative to the rotation groove A83, and the movable ball block A914 is located in the middle of the reverse limit cavity Block A914 can rotate in the triangular groove A911 to reduce the resistance of the limit column A912 on the upper movable triangular groove A911. When the top ring disk 91 rotates reversely relative to the rotating groove A83, the limit column A912 moves toward the shallow part of the triangular groove A911 under the friction resistance of the rotating groove A83, so that the rotating groove A83 locks the triangular groove A911 through the limit column A912, making the top ring disk 91 unable to rotate. Therefore, the top ring disk 91 cannot rotate reversely but can only rotate forward.

[0026] In the embodiment of the present invention, the rotating mechanism 4 includes a motor 41 and a transmission shaft 42. The motor 41 is fixed at the center of the top of the cover plate 33. The transmission shaft 42 is rotatably arranged at the bottom of the cover plate 33. The top of the transmission shaft 42 passes through the cover plate 33 and is fixedly connected to the output shaft of the motor 41. A slide bar 43 is arranged at the bottom of the transmission shaft 42. The slide bar 43 is provided with two connecting parts 44 in an upper and lower structure. A lifting guide groove 45 is opened on the surface of the transmission shaft 42. A lifting guide block 46 is movably connected to the lifting guide groove 45. A rotating column 47 is fixed on the lifting guide block 46. Through the above arrangement, the present invention allows the transmission shaft 42 and the slide bar 43 to rotate when the output shaft of the motor 41 is controlled to rotate by an external control mechanism.

[0027] In an embodiment of the present invention, the connecting portion 44 includes a connecting ring block 441, and the two connecting ring blocks 441 are fixedly connected to the two top ring disks 91 by a plurality of connecting rods 442 arranged in a ring-shaped structure with equal spacing. The connecting ring block 441 contacts and cooperates with the corresponding plurality of sealing plates 95. It is worth noting that the contact and cooperation between the connecting ring block 441 and the sealing plate 95 can be various, and can be selected according to the specific implementation situation, such as the bottom surface of the connecting ring block 441 contacts the centripetal end of the sealing plate 95 or the circumferential surface of the connecting ring block 441 contacts the centripetal end of the sealing plate 95 (when the plurality of sealing plates 95 are unfolded, they rotate while retreating outward, and there is no motion interference with the circumferential surface of the connecting ring block 441); a rotation groove B443 is provided on the inner edge surface of the connecting ring block 441, and a limited position ring block 444 is rotatably connected on the rotation groove B443, so that the position The upper limiting ring block 444 is slidably connected to the sliding rod 43, and the lower limiting ring block 444 is arranged below the sliding rod 43, and the lower limiting ring block 444 is slidably connected to the bottom end of the sliding rod 43 through a sliding tube 440, and a plurality of triangular grooves B445 are provided in a circular equidistant structure on the outer edge surface of the limiting ring block 444, and the gap between the triangular grooves B445 and the rotating grooves B443 constitutes a forward limiting cavity, and a limiting column B446 is provided in the forward limiting cavity, and the limiting column B446 is elastically connected to the deep part of the triangular grooves B445 through a spring B447, and movable ball blocks B448 are movably provided at both ends of the limiting column B446, and the movable ball block B448 is movably connected to the rotating groove B443, and a sleeve 449 is fixed on the top of the connecting ring block 441 located above, and the rotating column 47 is rotatably connected to the inner edge surface of the sleeve 449.The present invention further arranges the two connecting parts 44 so that the rotation of the slide rod 43 can drive the upper limit ring block 444 and the slide tube 440 to rotate, so that the lower limit ring block 444 rotates. Referring to the rotation principle of the top ring disk 91, it can be seen that the limit ring block 444 cannot rotate forward relative to the rotation groove B443, but can only rotate reversely relative to the rotation groove B443, so that when the slide rod 43 rotates forward, the limit ring block 444 drives the connecting ring block 441 to rotate through the limit column B446, and the connecting ring block 441 drives the top ring disk 91 to rotate through the connecting rod 442 to control the opening and closing of the iris assembly 9. At this time, the upper connecting ring block 441 drives the sleeve 449 to rotate, so that the rotating column 47 drives the lifting guide block 46 to rotate at the same speed as the transmission shaft 42. The lifting guide block 46 and the lifting guide groove 45 do not rotate relative to each other. When the slide bar 43 rotates in the reverse direction, the top ring disk 91 cannot rotate in the reverse direction, so that the connecting ring block 441 and the sleeve 449 cannot rotate in the reverse direction. At this time, the state of the iris assembly 9 remains unchanged, and the transmission shaft 42 drives the lifting guide groove 45 to rotate in the reverse direction, so that the lifting guide block 46 moves in the lifting guide groove 45, causing the rotating column 47 to drive the sleeve 449 to move up and down, so that the connecting ring block 441 located above is lifted and lowered, driving the entire connecting part 44 and the iris assembly 9 located above to move up and down, and the mounting ring block 82 and the mounting seat B81 located above are lifted and lowered along the slide groove 21 with the slider 22, so that the size of the quantitative dosing cavity surrounded by the two iris assemblies 9 and the pipeline assembly 8 is changed, so as to adjust the powder dosage.

[0028] In the embodiment of the present invention, the lifting guide groove 45 includes two thread guide grooves 451 arranged in a symmetrical structure, and both ends of the two thread guide grooves 451 are connected through the guide arc groove 452. The present invention further designs the lifting guide groove 45, and provides the guide arc groove 452 to facilitate the lifting guide block 46 to enter the other thread guide groove 451 from one thread guide groove 451.

[0029] Working principle: When the intelligent powder dosing device is in use, the external control mechanism controls the output shaft of the motor 41 to rotate in the reverse direction, and the transmission shaft 42 and the slide rod 43 both rotate. Since the top ring disk 91 cannot rotate in the reverse direction, the connecting ring block 441 and the sleeve 449 cannot rotate in the reverse direction. At this time, the state of the iris assembly 9 remains unchanged, and the transmission shaft 42 drives the lifting guide groove 45 to rotate in the reverse direction, so that the lifting guide block 46 moves in the lifting guide groove 45, causing the rotating column 47 to drive the sleeve 449 to move up and down, so that the upper connecting ring block 441 is lifted and lowered, driving the entire connecting part 44 and the upper iris assembly 9 to lift and lower, and the upper mounting ring block 82 and the mounting seat B81 are lifted and lowered along the slide groove 21 with the slider 22, so that the size of the quantitative dosing cavity surrounded by the two iris assemblies 9 and the pipeline assembly 8 changes, thereby adjusting the powder dosage.
