Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material screening equipment, in particular to a sealed medicinal material powder screening equipment. Background Art

[0002] Medicinal powder with uniform particle size is more conducive to the stability and long-term storage of the drug. Powder with uneven particle size may cause stratification and agglomeration during storage, affecting the stability and efficacy of the drug. Therefore, it is necessary to screen the powder to make it uniform in particle size, which can reduce the occurrence of these phenomena and thus improve the stability of the drug.

[0003] In the related art, the screening equipment uses screen vibration when screening medicinal powder. The material on the screen surface is affected by this vibration and will continuously jump and roll forward, thereby achieving material screening. Since the mesh size of the screen is fixed, the screening equipment can only screen out medicinal powder of a specific particle size. When it is necessary to screen medicinal powder of different particle sizes, it is necessary to replace the screens of different mesh sizes, which not only increases the complexity of the operation, but may also affect the production efficiency. Therefore, those skilled in the art provide a sealed medicinal powder screening equipment to solve the problems raised in the above background technology. Utility Model Content

[0029] A screening box 1, a feed cover 2 is provided at the upper end of the screening box 1, a sealing cover 3 is connected to the feed cover 2, a collection drawer 4 is installed at the lower end of the screening box 1, the collection drawer 4 is connected to the screening box 1 through a fixing bolt 19, and a pull handle 20 is provided on the collection drawer 4;

[0030] The setting of the feed cover 2 facilitates the entry of medicinal powder into the screening box 1; the setting of the sealing cover 3 allows the feed cover 2 to be shielded during screening to prevent the powder from flying out of the feed cover 2; the setting of the collection drawer 4 allows the medicinal powder to be collected; the setting of the fixing bolts 19 allows the collection drawer 4 to be disassembled to process the collected medicinal powder; and the setting of the pull handle 20 allows the collection drawer 4 to be taken out easily.

[0031] A discharge port 5 is provided on one side of the screening box 1, an electric push rod 6 is installed on the screening box 1, a baffle 7 is connected to the output end of the electric push rod 6, L-shaped limit plates 21 are fixedly provided on both sides of the discharge port 5, and the baffle 7 is slidably connected between the two L-shaped limit plates 21;

[0032] The sieved material is discharged through the discharge port 5. When being discharged through the discharge port 5, the electric push rod 6 drives the baffle 7 to move. After the discharge port 5 leaks out, the sieved medicinal powder is discharged through the discharge port 5. When the material is stopped, the electric push rod 6 drives the baffle 7 to block the discharge port 5. The L-shaped limiting plate 21 is set to limit the two sides of the baffle 7.

[0033] A rotating frame 9 is rotatably connected to the screening box 1 through a rotating rod 8, a servo motor 10 is installed on the screening box 1, and the output end of the servo motor 10 is connected to the extended end of the rotating rod 8 that passes through the screening box 1, and a mounting frame 11 is fixedly provided in the screening box 1, and the first screen 12 and the second screen 13 are respectively connected to the mounting frame 11 and the rotating frame 9 at both ends through a clamping assembly, and the clamping assembly includes a reset spring 22 and two clamping blocks 23, and both sides of the first screen 12 and the second screen 13 are provided with limit blocks 24, and the mounting frame 11 and the rotating frame 9 are provided with limit grooves 25 for the limit blocks 24 to engage, and a first mounting groove 26 for the reset spring 22 to be installed is provided in the limit block 24, and the two clamping blocks 23 are respectively connected to the two ends of the reset spring 22, and clamping grooves 27 are provided at both ends of the limit groove 25, and the clamping block 23 passes through the first mounting groove 26 and is clamped in the clamping groove 27;

[0034] Since the mesh number of the first screen 12 is greater than the mesh number of the second screen 13, when screening coarser medicinal material powder, the servo motor 10 drives one end of the rotating frame 9 to rotate through the rotating rod 8, thereby driving the other end of the rotating frame 9 to rotate, so that the rotating frame 9 rotates to be in contact with the side wall of the screening box 1, and the second screen 13 is also in contact with the side wall of the screening box 1. The medicinal material powder enters the screening box 1 through the feed cover 2, and the medicinal material powder is screened through the first screen 12. The screened medicinal material powder enters the collecting drawer 4, and the screened medicinal material powder is discharged from the discharge port 5;

[0035] When adjusting the screening, the servo motor 10 drives one end of the rotating frame 9 to rotate through the rotating rod 8, thereby driving the other end of the rotating frame 9 to rotate, so that the rotating frame 9 rotates to contact and connect with the mounting frame 11, and the first screen 12 and the second screen 13 are in contact and connected, so that the screening mesh number can be changed, and the mesh size of the screening net can be automatically adjusted to screen different medicinal powders, thereby improving the screening efficiency.

[0036] A vibration motor 14 is installed at the lower end of the screening box 1. A plurality of buffer components are provided at the lower end of the screening box 1. The buffer components include a support member 28, a connecting rod 29 and a buffer spring 30. One end of the support member 28 is connected to the screening box 1. A second installation groove 31 for installing the buffer spring 30 is opened in the connecting rod 29. The other end of the support member 28 passes through the second installation groove 31 and is connected to one end of the buffer spring 30. A support plate 32 is provided at the end of the connecting rod 29 away from the support member 28, and an anti-slip pad 33 is provided on the support plate 32.

[0037] During vibration screening, the vibration motor 14 drives the screening box 1 to vibrate. When the screening box 1 vibrates, the support member 28 squeezes the buffer spring 30, and the buffer spring 30 releases elastic potential energy, which drives the screening box 1 to vibrate. The medicinal material powder is subjected to the vibration on the screen surface of the first screen 12, and will continuously jump and roll forward, thereby achieving screening of the medicinal material powder.

[0038] The anti-skid pad 33 can improve the anti-skid effect of the support plate 32 .

[0039] Furthermore, an inspection port 15 is provided on the screening box 1, and an inspection door 17 is installed at the inspection port 15 by installing bolts 16, and a sealing edge 18 is provided between the inspection door 17 and the screening box 1. When inspecting the screening box 1, the installing bolts 16 are removed, and then the inspection door 17 is removed to expose the inspection port 15 for inspection and use.
