[0002] With the vigorous development of the pharmaceutical industry, the application of pharmaceutical equipment is also increasing, including: crusher, slicer, stir-frying machine, decoction machine, tablet press, pill making machine, multi-functional extraction tank, etc. In the process of powdered drug processing, large particles of drugs need to be crushed into powder.

[0003] Most existing crushing equipment uses rollers to crush. The rollers are prone to sliding with larger drug particles during the extrusion process, which results in the large agglomerated drug particles being unable to enter the gap between the two rollers. This affects the crushing efficiency and the crushing effect is also poor. Therefore, it is necessary to preliminarily crush the larger drug particles.

[0004] In the prior art, patent number CN212915783U discloses a powder pharmaceutical machinery and equipment, including a device housing, a first motor and a second motor are respectively installed on the side of the device housing, a first guide plate is arranged on the top of the device housing, two mutually parallel rubbing plates are arranged on the lower side of the first guide plate, the two rubbing plates are slidably connected with the device housing, the facing sides of the rubbing plates are provided with a plurality of ridges, the back side of the rubbing plates are fixed with racks, the side of each rubbing plate is provided with a first gear, the first gear is meshed with the rack, the interior of the two first gears is embedded with a first rotating shaft, one end of the two first rotating shafts is provided with a pulley, a belt is connected between the two pulleys, the other end of one of the two first rotating shafts is connected to the output shaft of the first motor, the lower side of the two rubbing plates is provided with a second guide plate, and the lower side of the second guide plate is provided with two mutually parallel rolling rollers. The powder pharmaceutical machinery and equipment has high crushing efficiency and good crushing effect.

[0005] Although this technical solution can improve the pulverizing efficiency and pulverizing effect of pharmaceutical machinery and equipment, large particles of drugs may still exist in the drug powder after being pulverized by the equipment. The above technical solution lacks a screening component for the drugs after pulverization when used. Therefore, the drug powder exported from the device needs to be screened before it can be put into the next production step, which is more troublesome. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] This kind of powder pharmaceutical machinery and equipment sets a screen above the discharge port of the pulverizing device body. After the main body component inside the device pulverizes the drug, the pulverized drug falls on the upper surface of the screen, and then the drug powder that meets the requirements falls to the bottom of the pulverizing device body under the action of gravity.

[0026] See also Figure 1-3 A powder pharmaceutical machinery and equipment comprises a pulverizing device body 1, a discharging port is penetrated through the outer wall at the lower end of the pulverizing device body 1, a movable door 2 is rotatably installed inside the discharging port, a screen 4 is movably installed at the lower end of the inner part of the pulverizing device body 1, and a material guide port is opened at the outer wall of the pulverizing device body 1 and the corresponding position of the screen 4.

[0027] The powdered pharmaceutical machinery and equipment proposed in the utility model, when in use, the medicine to be crushed is put into the device from the upper end of the crushing equipment body 1, and the medicine powder can be taken out from the discharge port after being crushed by the internal components of the crushing equipment body 1. The main structure in the technical scheme is similar to the main structure of a powdered pharmaceutical machinery and equipment disclosed in Patent No. CN212915783U. During the use of the present technical scheme, the medicine powder after being crushed by the internal components of the crushing equipment body 1 falls on the upper surface of the screen 4. Under the action of the medicine's own gravity, the medicine powder that meets the requirements passes through the screen 4 and falls to the bottom of the equipment, and the large medicine particles that do not meet the requirements accumulate on the surface of the screen 4. The user can take out the large particles of medicine accumulated on the surface of the screen 4 from the guide port and re-introduce it into the crushing equipment body 1 for crushing. The medicine powder that meets the requirements can be taken out through the discharge port and directly put into the next production step. The setting of the screen 4 makes it unnecessary for the user to additionally screen the crushed medicine, thereby simplifying the production steps of the medicine.

[0028] Furthermore, if Figure 2 As shown, a rotating rod 9 is rotatably installed inside the pulverizing equipment body 1 below the screen 4, a motor is fixedly installed at a position corresponding to the outer wall of the pulverizing equipment body 1 and the rotating rod 9, the output end of the motor is fixedly connected to the rotating rod 9, and an extrusion wheel 10 is fixedly installed on the outer wall of the rotating rod 9. When in use, the motor drives the rotating rod 9 to rotate and then drives the extrusion wheel 10 to squeeze the bottom of the screen 4. The rotating rod 9 is arranged in the middle position of the bottom of the screen 4, and the number of the extrusion wheels 10 is two groups, which are respectively arranged at both ends of the rotating rod 9. When the extrusion wheel 10 squeezes the screen 4, the screen 4 can be deformed. When the screen 4 is deformed, the mesh thereon can be prevented from being blocked, and the screening efficiency of the screen 4 can also be accelerated. At the same time, when the extrusion wheel 10 squeezes the screen 4, its overall shape can be made to be convex upward.

[0029] Furthermore, if Figure 3 As shown, the inner wall of the pulverizing equipment body 1 is located below the two ends of the screen 4 and a support block 6 is fixedly installed, and a movable block 7 is slidably installed above the support block 6. The upper end surface of the movable block 7 is hinged to the end of the screen 4, and sliders 8 are fixedly installed at both ends of the movable block 7. The inner wall of the pulverizing equipment body 1 and the corresponding positions of the sliders 8 are provided with sliding grooves matched with the sliders 8. When in use, when the screen 4 is in the expanded state, it matches the bottom surface of the pulverizing equipment body 1. When the rotating rod 9 drives the extrusion wheel 10 to squeeze the middle position of the screen 4, the middle position of the screen 4 bulges upward, and its two ends drive the movable blocks 7 to slide and approach each other. In the process of deformation of the screen 4, the inside of the mesh on it can be prevented from being blocked by drug powder. At the same time, when the screen 4 maintains a state of bulging upward in the middle, it can assist the drug powder on its surface that does not meet the requirements to fall along the surface of the screen 4 and accumulate on the support block 6. At this time, the user can take out the large particles of drugs that do not meet the requirements through the guide port.

[0030] Furthermore, if Figure 3 As shown, the upper end of the movable block 7 is chamfered, and the side of the upper end surface of the movable block 7 close to the material guide port is chamfered, and the end of the screen 4 is hinged to the outer wall surface of the upper end surface of the movable block 7 with the chamfer.

[0031] Furthermore, if Figure 3 As shown, the cross section of the support block 6 is L-shaped, and the short side of the support block 6 is protruded upward. The protrusion of the short side of the support block 6 can block and limit the movable block 7 when it slides, thereby preventing it from detaching from the support block 6 when sliding.

[0032] Furthermore, if Figure 2 As shown, a guide plate 3 is hinged inside the guide port, and the lower end of the guide plate 3 is hinged to the wall of the guide port. When the guide plate 3 is flipped outward, it can guide the large particle medicine on the upper surface of the screen 4 to facilitate its removal. At the same time, the cross-section of the guide plate 3 is U-shaped. The special setting of the guide plate 3 can form side guard plates on both sides thereof to prevent large particle medicine particles from falling from both sides of the guide plate 3 when being taken out.

[0033] Furthermore, if Figure 2 As shown, a guide plate 5 is fixedly installed at the bottom of the pulverizing equipment body 1, and the cross-section of the guide plate 5 is triangular, wherein the end of the guide plate 5 close to the discharge port is lower, and the end away from the discharge port is higher. Under the action of the guide plate 5, the drug powder falling on the guide plate 5 can slide along the inclined surface of the guide plate 5 and accumulate at the discharge port.

[0034] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
