[0002] Bear bile powder is a Chinese patent medicine obtained by processing bear bile and freeze-drying it at low temperature. It has the effects of protecting the liver, promoting bile secretion, and resisting fatty liver.

[0003] For example, the invention patent with authorization announcement number CN118150411A in the field of metering and detection technology discloses a large-particle dust metering device including a particle separation bin, a particle size screening component and a particle metering component, the particle separation bin is provided with a filling port, the filling port cover is provided with a sealing plug, the interior of the particle separation bin is provided with a dust activity chamber, the dust activity chamber is provided with a vibration separation component, the vibration separation component is located below the filling port, the outer edge of the particle separation bin is provided with a dust raising component, the dust raising component is connected to the dust activity chamber; the particle size screening component is connected to the particle separation bin, and the particle separation bin is provided with a sealing connector protruding toward the particle size screening component.

[0004] Combining the above cases with actual situations, we found the following problems: After the bear bile is freeze-dried into powder, the freeze-dried powder needs to be screened to remove the powder particles that do not meet the particle size requirements to ensure subsequent quality. In the actual process, the screening and metering steps are usually separated, which can easily cause metering errors during the movement process. At the same time, the many steps are not convenient for subsequent metering.

S2, after adjusting the metering cylinder to a suitable position, the freeze-dried and crushed bear bile powder is fed into the box from the feed port, and then the servo motor is started to drive the cam to rotate through the first transmission rod, the second transmission rod and the third transmission rod in sequence, so that the sieve frame is continuously pushed up and vibrated, so that the bear bile powder that meets the particle size requirements falls; S3.

[0017] 2. In the present invention, by arranging a material pressing assembly and a metering assembly, while vibrating, the vertical rod and the screen frame move up and down synchronously and are driven by the transmission rod to make the connecting rod rotate clockwise along the connecting channel, thereby driving the active gear to rotate and driving the half gear to rotate synchronously through the driven gear, and the tooth groove will press the pressing rod down to drive the pressing plate to move downward, so that the inclined rods on both sides slide outward and drive the cross rod to slide outward through the rod sleeve and the sliding rod, thereby pulling open the door panels on both sides, and the bear bile powder can be released at this time, and the powder released each time is the powder between the bottom surface of the metering cylinder and the top nozzle of the discharge pipe, thereby realizing quantitative metering.

[0018] 3.

[0020] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0021] Unless explicitly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood as including the stated elements or components but not excluding other elements or components.

[0022] Reference Figure 1-Figure 12 As shown, this embodiment provides a technical solution: A metering device for processing bear bile powder, comprising a metering box 1, the metering box 1 comprising a box body 11, a feed port 12 arranged at the middle of the top surface of the box body 11, and a discharge pipe 15 arranged at the box body 11, a vibration component 2 for screening bear bile powder of qualified particle size is arranged at the upper part of the box body 11, the vibration component 2 comprises a screen frame 22 and a driving structure 21 for driving the screen frame 22 to vibrate up and down, a pressing component 3 for pressing the bear bile powder is arranged below the vibration component 2, and a metering component 4 for quantitatively measuring the bear bile powder is arranged in the discharge pipe 15, by arranging the vibration component 2, the bear bile powder that does not meet the required particle size can be dried out before quantitative measurement, so as to avoid affecting the subsequent packaging and product quality, and by arranging the pressing component 3 and the metering component 4, the bear bile powder can be quantitatively measured intermittently, so as to facilitate the subsequent packaging; The material pressing assembly 3 includes a fixed cylinder 31 fixed in the box body 11, a linkage structure 32 arranged in the fixed cylinder 31, and a pressure plate structure 35 arranged below the fixed cylinder 31. The linkage structure 32 includes a vertical rod 321 fixed at the top and the middle of the bottom surface of the screen frame 22 near the rear side, a transmission rod 322 hinged at the top and the bottom end of the vertical rod 321, and a connecting rod 323 rotatably connected at the rear end and the front side of the bottom end of the transmission rod 322. When the screen frame 22 vibrates up and down, the vertical rod 321 will move up and down synchronously with the screen frame 22. A driving tooth 324 is provided at the front end of the connecting rod 323, a fixing seat 327 is provided below the driving tooth 324, an outer ring 328 is fixed above the middle of the fixing seat 327, the upper horizontal section of the fixing seat 327 coaxially passes through the driving tooth 324, and an annular connecting channel 329 is provided between the rear end of the upper horizontal section of the fixing seat 327 and the inner ring wall of the outer ring 328, and the connecting rod 323 passes through the connecting channel 329. Due to the restriction of the connecting channel 329, when the vertical rod 321 moves up and down, the connecting rod 323 will rotate along the connecting channel 329, thereby driving the driving tooth 324 in front to rotate synchronously clockwise; A rotating shaft 33 is provided on the left side of the bottom of the fixed cylinder 31, and a driven tooth 325 meshing with the driving tooth 324 is coaxially fixed to the rear side of the rotating shaft 33. A half gear 34 is coaxially fixed to the middle of the rotating shaft 33. When the driving tooth 324 rotates, the rotating shaft 33 is driven to rotate through the driven tooth 325, thereby driving the half gear 34 to rotate. It should be noted that the diameter of the driving tooth 324 is smaller than the diameter of the driven tooth 325. Since the vibration amplitude of the screen frame 22 is small and the vibration speed is fast, the vertical rod 321 moves up and down. The distance is small and the speed is fast. The small diameter of the active tooth 324 can reduce the rotation speed of the driven tooth 325 when transmitting to the driven tooth 325, so as to avoid the driven tooth 325 from rotating too fast, causing the half gear 34 to quickly drive the pressure plate structure 35 to move up and down, which will not only shorten the service life of the pressure plate structure 35, but also shorten the interval time of the pressure plate structure 35 moving up and down, resulting in the inability of the bear bile powder to completely fill the part between the bottom surface of the metering cylinder 42 and the top nozzle of the discharge pipe 15, resulting in inaccurate quantitative measurement each time; The pressure plate structure 35 includes a pressure plate 351 and a pressure rod 352 fixed to the top surface of the pressure plate 351. The side wall of the pressure rod 352 is provided with a plurality of tooth grooves 352a regularly distributed up and down and corresponding to the teeth of the half gear 34. When the half gear 34 rotates, it presses the pressure rod 352 downward through the tooth grooves 352a. When the other half side of the half gear 34 without the tooth block rotates to face the pressure rod 352, the third spring 354 will drive the pressure rod 352 and the pressure plate 351 to move up and reset.

[0023] In addition, if Figure 1-Figure 3As shown, an outer frame 13 is provided on the left side of the top of the outer wall of the box body 11, and the driving structure 21 includes a servo motor 211, two first transmission rods 213 distributed on the left and right, two second transmission rods 215 vertically arranged with the first transmission rods 213 on the corresponding side, and two third transmission rods 216 vertically arranged with the second transmission rods 215 on the corresponding side. The two first transmission rods 213 and the output shaft of the servo motor 211 are driven by a first gear set 212, and the second transmission rod 215 and the first transmission rod 213 on the corresponding side and the second transmission rod 215 and the third transmission rod 216 are both driven by a second gear set 214. An overhanging plate 221 is fixed to the middle of the left and right side walls of the frame 22, and a cam 217 is coaxially fixed to the inner end of the third transmission rod 216. The cam 217 is located directly below the overhanging plate 221 on the corresponding side. The first gear set 212 is three mutually meshing bevel gears, and the second gear set 214 is two mutually meshing bevel gears. When in use, the servo motor 211 is started to drive the cam 217 to rotate continuously through the sequential transmission of the first transmission rod 213, the second transmission rod 215 and the third transmission rod 216. When the protruding part of the cam 217 can continuously push up the overhanging plate 221, the sieve frame 22 vibrates up and down, and the bear bile powder that meets the particle size requirements is sieved down; Further, a vibration frame 14 is provided in the middle of the front and rear side walls of the screen frame 22, and a limit plate 23 is fixed in the middle of the front and rear outer walls of the screen frame 22. A limit rod 24 is fixed between the upper and lower inner walls of the vibration frame 14, and the limit rod 24 passes through the limit plate 23 and the two are slidably connected. The outer wall of the limit rod 24 is located between the inner bottom surface of the vibration frame 14 and the bottom surface of the limit plate 23 and is sleeved with a first spring 25. By arranging the limit plate 23 and the limit rod 24, the screen frame 22 can only vibrate up and down, thereby improving the stability of the vibration. At the same time, the screen frame 22 that is lifted up under the action of the first spring 25 can be quickly pulled down, so that the screen frame 22 can quickly vibrate up and down; In addition, if Figure 4-Figure 9 As shown, the top surface of the fixed cylinder 31 is conical to prevent the falling bear bile powder from accumulating on the top surface of the fixed cylinder 31. The fixed cylinder 31 is fixed in the box body 11 by rods fixed on the left and right side walls, which are not shown in the figure. The bottom end of the vertical rod 321 passes through the top surface of the fixed cylinder 31 and extends into the interior of the fixed cylinder 31. The maximum height of the bottom end of the vertical rod 321 is less than the distance between the top surface of the fixed cylinder 31 and the bottom end of the vertical rod 321, so as to prevent the vertical rod 321 from being separated from the fixed cylinder 31. The active tooth 324 is located on the front side of the outer ring 328, and the front end of the connecting rod 323 is fixed to the rear side wall of the active tooth 324 against the outer wall. The active tooth 324 is coaxially arranged with the annular connecting channel 329, so that the rotation center of the connecting rod 323 and the center of the circle of the active tooth 324 are coaxial. The second spring 323c is provided on the outer wall of the lever 328 so that the lever 328 is in a state of being rotated in a clockwise direction so as to prevent the lever 328 from rotating and thus causing the lever 328 to rotate in a clockwise direction. In addition, an insertion rod 353 is fixed to the middle of the top surface of the fixed cylinder 31, and a sliding cavity 352b is provided in the pressure rod 352 near the top. The bottom end of the insertion rod 353 is inserted into the sliding cavity 352b and the two slide relative to each other. The outer wall of the insertion rod 353 is located between the top surface of the pressure rod 352 and the bottom edge of the insertion rod 353, and a third spring 354 is sleeved. The radius of the pressure plate 351 is the same as the inner radius of the discharge pipe 15, ensuring that when the pressure plate 351 moves down to the top of the discharge pipe 15, the bear bile powder above will not enter between the bottom surface of the metering cylinder 42 and the top of the discharge pipe 15. By providing the insertion rod 353, the pressure rod 352 can only move up and down along the insertion rod 353. By providing the third spring 354, the pressure rod 352 can be driven to reset upward after the half gear 34 and the tooth groove 352a are completely disengaged. In addition, if Figure 10-12 As shown, the metering assembly 4 includes an opening and closing structure 41 arranged on the outer wall of the discharge pipe 15 and a metering cylinder 42 arranged in the discharge pipe 15. The outer wall of the metering cylinder 42 fits with the inner wall of the discharge pipe 15 to prevent the falling bear bile powder from entering the gap between the discharge pipe 15 and the metering cylinder 42. A card slot 421 is provided near the bottom of the wall of the metering cylinder 42, and a card plate 451 is provided in the card slot 421. A handle 45 is fixed to the middle of the outer wall of the card plate 451. The card plate 451 can be controlled to rotate along the card slot 421 by holding the handle 45. An adjusting groove 151 is provided at the outer wall of the discharge pipe 15 corresponding to the handle 45. The outer end of the handle 45 passes through the adjusting groove 151 and extends out of the discharge pipe 15. The left side of the adjusting groove 151 is a vertical part and the right side is a placement part. When the quantitative adjustment is required, it is only necessary to hold the handle 45 to lift the entire metering cylinder 42 upwards, and then rotate the handle 45 to exit the placement part and enter the vertical part, and then move the handle 45 up and down to enter the appropriate placement part to complete the adjustment; Furthermore, the opening and closing structure 41 includes a mounting frame 411 symmetrically arranged on the outer wall of the discharge pipe 15, and a push-pull mechanism 412 is arranged in the mounting frame 411. The push-pull mechanism 412 includes a sloped rod 4121 horizontally arranged at the top of the discharge pipe 15, a rod sleeve 4124 vertically fixed to the bottom of the outer end of the sloped rod 4121, and a sliding rod 4125 with the top inserted into the rod sleeve 4124. The portion of the inner end of the sloped rod 4121 located inside the discharge pipe 15 is a slope and the slope is arranged upward. The sloped rod 4121 is arranged at the top of the discharge pipe 15 to ensure that the pressure plate 351 can contact the sloped rod 4121 when pressed down, so as to avoid the pressure plate 351 being unable to directly contact the sloped rod 4121 due to the difficulty in compressing the bear bile powder when it is fully filled. The discharge pipe 15 extends into the installation frame 411, and a movable rod 4123 is fixed at the corresponding position of the installation frame 411 and the inner wall and the inclined rod 4121. The inner end of the movable rod 4123 extends into the inclined rod 4121 and the two slide relative to each other. A fourth spring 4122 is provided between the inclined rod 4121 and the inner end of the movable rod 4123. When the pressure plate 351 is pressed down to contact the inclined rod 4121, the inclined rod 4121 will slide to the outside and compress the fourth spring 4122. The inclined rod 4121 simultaneously pulls the cross bar 4126 outward under the transmission of the rod sleeve 4124 and the sliding rod 4125. It should be noted that the maximum downward movement position of the pressure plate 351 is located above the lowest end of the inclined rod 4121, so as to prevent the pressure plate 351 from moving down to the bottom of the inclined rod 4121, which makes it impossible for the pressure plate 351 to be reset. Specifically, the rod sleeve 4124 slides relatively with the slide bar 4125. When the metering cylinder 42 moves up and down to adjust the quantitative amount, the slide bar 4125 can slide upward with the metering cylinder 42. The bottom end of the movable rod 4123 is fixedly connected with a horizontal cross bar 4126. It should be noted that the discharge pipe 15 is provided with a vertical vertical groove at a position corresponding to the position of the cross bar 4126. The vertical groove is provided to facilitate the synchronous up and down movement of the cross bar 4126 and the metering cylinder 42. At the same time, the lowest position of the top of the metering cylinder 42 is higher than the highest end of the vertical groove to prevent the bear bile powder from falling out of the vertical groove. Furthermore, door panels 43 are symmetrically provided at the bottom outlet of the metering cylinder 42, and the inner end of the cross bar 4126 passes through the discharge pipe 15 and the metering cylinder 42 from the outside to the inside in sequence and is fixedly connected to the middle of the outer wall of the corresponding side door panel 43. The side wall of the metering cylinder 42 is provided with a groove for the door panel 43 to slide outward. When the cross bar 4126 is pulled outward, the door panel 43 will be pulled outward and opened synchronously. At this time, the bear bile powder can fall out of the bottom of the metering cylinder 42 for collection, and an inclined panel 44 is symmetrically fixed to the inner wall of the metering cylinder 42 above the door panel 43. By setting the inclined panel 44, the gap between the door panel 43 and the inner wall of the metering cylinder 42 can be blocked to avoid the existence of a gap when closed.

[0024] The metering method for processing bear bile powder in the present invention comprises the following steps: S1, lift the handle 45 to make it leave the placement part on the right side of the adjustment groove 151 and enter the vertical part on the left side, then select a suitable placement part to place the handle 45, change the distance from the bottom surface of the metering cylinder 42 to the top of the discharge pipe 15, and then change the quantitative value; S2, after adjusting the metering cylinder 42 to a suitable position, the freeze-dried and crushed bear bile powder is fed into the box body 11 from the feed port 12, and then the servo motor 211 is started to drive the cam 217 to rotate through the first transmission rod 213, the second transmission rod 215 and the third transmission rod 216 in sequence, thereby continuously pushing up and vibrating the sieve frame 22, so that the bear bile powder that meets the particle size requirements falls; S3, when the screen frame 22 vibrates up and down, the vertical rod 321 moves up and down synchronously with the screen frame 22 and is driven by the transmission rod 322 to make the connecting rod 323 rotate clockwise along the connecting channel 329, thereby driving the driving tooth 324 to rotate and driving the half gear 34 to rotate synchronously through the driven tooth 325. When the half gear 34 rotates, the tooth portion of the half gear 34 presses down the pressing rod 352 through the tooth groove 352a to drive the pressing plate 351 to move downward; S4, when the pressing plate 351 moves down to the top opening of the discharge pipe 15, it will contact the inclined rod 4121, and make the inclined rods 4121 on both sides slide outwards and drive the cross bar 4126 to slide outwards through the rod sleeve 4124 and the slide rod 4125, thereby pulling open the door panels 43 on both sides, and at this time, the bear bile powder between the bottom surface of the metering cylinder 42 and the top opening of the discharge pipe 15 is released; S5. When the half gear 34 rotates to the point where it cannot contact the tooth groove 352a, the third spring 354 will pull the pressure rod 352 and the pressure plate 351 upward, causing the pressure plate 351 to separate from the discharge pipe 15. At this time, the bear bile powder can fall back into the space between the bottom surface of the metering cylinder 42 and the top opening of the discharge pipe 15. Then, steps S2-S4 can be repeated to achieve continuous quantitative metering.
