[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0024] This embodiment provides an automatic weighing and dispensing module for medicinal powder.

[0025] Reference Figure 1-4 An automatic powder weighing and dispensing module includes an automatic powder adding mechanism 1 for adding powder and a weighing mechanism 2 for weighing.

[0026] The automatic powder dispensing mechanism 1 includes a powder dispensing bracket 11, a sliding frame 12, a drive assembly 13, a powder dispensing shaft 14, and a powder bucket frame 15. The powder dispensing bracket 11 can move in both horizontal and vertical directions. The sliding frame 12 is vertically slidably connected to the powder dispensing bracket 11. The drive assembly 13 is used to drive the sliding frame 12 to slide vertically along the powder dispensing bracket 11 for a certain distance.

[0027] The drive assembly 13 includes a drive motor 131 and a cam 132. The drive motor 131 is horizontally mounted on the powder feeding bracket 11. One end of the cam 132 is fixedly connected to the drive motor 131, and the other end is rotatably connected to a connecting shaft 1321. The connecting shaft 1321 is horizontally connected to a sliding groove 121 mounted on the sliding frame 12 to achieve vertical reciprocating sliding drive of the sliding frame 12 along the powder feeding bracket 11.

[0028] The powder outlet shaft 14 is located on the side of the sliding frame 12 opposite to the drive assembly 13, and can slide vertically a certain distance together with the sliding frame 12. The powder bucket frame 15 is used to support the powder bucket 3, which includes a bucket body 31 and a guide rod 32 vertically slidably connected inside the bucket body 31. The upper end of the guide rod 32 passes through the top of the bucket body 31, and the lower end extends to the powder outlet of the bucket body 31, where a shaped opening 321 and a sealing end 322 are sequentially provided. A return spring 323 is also sleeved on the guide rod 32 to drive it to slide vertically upward and reset.

[0029] When adding powder, the drive component 13 controls the sliding frame 12 to slide vertically downwards, the powder outlet shaft 14 abuts against the upper end of the guide rod 32 and drives it to slide vertically downwards a certain distance. At this time, the irregular opening 321 set on the guide rod 32 is connected to the powder outlet, and powder can be dispensed from the powder outlet.

[0030] After the powder dispensing operation is completed, the drive assembly 13 controls the sliding frame 12 to slide vertically upward, the powder dispensing shaft 14 and the guide rod 32 disengage, and the guide rod 32 is reset under the action of the reset spring 323. At this time, the sealing end 322 of the guide rod 32 seals the powder outlet again, and the powder outlet is closed.

[0031] To prevent the powder outlet of the powder bucket 3 from being blocked by the powder during the powder addition process, a scraper 324 located above the irregular opening 321 can also be provided on the guide rod 32. The guide rod 32 can slide vertically along the bucket body 31 and rotate at the same time to stir the powder during the powder addition process and ensure normal output of the powder.

[0032] The rotation drive of the guide rod 32 is also achieved through the powder outlet shaft 14, which is rotatably connected to the sliding frame 12. When a motor is connected to the powder outlet shaft 14, it can rotate. The lower end of the powder outlet shaft 14 is provided with an irregularly shaped connecting end 141, and the upper end surface of the guide rod 32 is provided with an irregularly shaped groove 325. The irregularly shaped groove 325 matches the shape of the connecting end 141 and allows the connecting end 141 to be inserted and engaged.

[0033] When adding powder, the drive assembly 13 controls the vertical downward sliding. The connecting end 141 of the powder discharge shaft 14 first embeds into the irregular groove 325 on the guide rod 32, and then drives the guide rod 32 to slide down a certain distance. The irregular opening 321 on the guide rod 32 is connected to the powder discharge port. Then the motor drives the powder discharge shaft 14 to rotate, and then drives the guide rod 32 to rotate through the cooperation of the connecting end 141 and the irregular groove 325. At this time, the scraper 324 stirs the powder in the barrel 31 to ensure that the powder discharge port is in a normal powder discharge state.

[0034] To further ensure the normal discharge of powder from the powder outlet of powder hopper 3, a vibration motor can be further installed on the sliding frame 12.

[0035] The weighing mechanism 2 includes a balance 21, which is located below the powder feeding bracket 11.

[0036] To facilitate easy replacement of the powder bucket 3, the powder bucket rack 15, the powder filling bracket 11, and the powder bucket 3 are all detachably connected. The powder bucket rack 15 includes a U-shaped support block 151, with a support hole 1511 for placing the powder bucket 3 in the middle, an L-shaped handle 1512 at the protruding end, and at least one connecting wing plate 1513 with a connecting groove on each side. The powder filling bracket 11 is provided with at least one pair of L-shaped hooks 111 for hooking into the connecting grooves respectively.

[0037] When replacing powder bucket 3, the robot set in other workstations of the automated experimental device for pre-processing of traditional Chinese medicine analysis drives the U-shaped support block 151 to move upward by gripping the L-shaped handle 1512, so that the L-shaped hook 111 is disengaged from the connecting groove, and at this time the powder bucket frame 15 can be disengaged from the powder feeding bracket 11.

[0038] Then, place the powder bucket holder 15 in an empty workstation. At this time, the robot clamps the powder bucket 3, causing the powder bucket 3 to detach from the powder bucket holder 15. Simultaneously, place the new powder bucket 3 into the bearing hole 1511. Then, place the powder bucket holder 15 in an empty workstation again. The robot clamps the L-shaped handle 1512. Then, through the cooperation of the L-shaped hook 111 and the connecting groove, the powder bucket holder 15 is installed on the powder filling bracket 11, thus realizing the replacement of the powder bucket 3.

[0039] In the specific implementation process, a pair of connecting wing plates 1513 on both sides of the U-shaped bearing block 151 are preferably provided, and the pair of connecting wing plates 1513 are arranged side by side. At the same time, the powder feeding bracket 11 is provided with the same number of L-shaped hook strips 111 as the connecting wing plates 1513, so as to ensure the connection stability of the powder barrel 3 frame 15 and the powder feeding bracket 11.

[0040] To further ensure the connection stability between the powder hopper 3 frame 15 and the powder feeding bracket 11, an adsorption magnet for sucking in the powder feeding bracket 11 can be provided on the inner side of the U-shaped support block 151.

[0041] In this application, the movement of the powder feeding bracket 11 in the horizontal and vertical directions can be achieved by common structures such as ball screws / trapezoidal screws, synchronous belts / toothed belts, gear racks, hydraulic cylinders, and pneumatic cylinders.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
