[0002] Pharmaceutical production inspection refers to the quality control and testing of raw materials, intermediate products, finished products, and the production environment during the pharmaceutical production process, using a series of scientific methods and means.

[0003] Grinding is an important step in pharmaceutical production and testing. Its main purpose is to ensure the uniformity and representativeness of the sample, thereby improving the accuracy and reliability of the test results. However, traditional grinding methods are time-consuming and labor-intensive. For example, if a cutting blade is used to rotate at high speed, the high temperature can easily cause the medicinal properties of the herbs to volatilize, affecting the accuracy of the pharmaceutical test.

[0004] Now, a novel pharmaceutical grinding device for pharmaceutical production and testing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pharmaceutical grinding device for pharmaceutical production and testing, in order to solve the problems mentioned in the background art, such as the time-consuming and labor-intensive traditional grinding methods and the volatilization of pharmaceutical properties caused by the high-speed rotation of the cutting blade.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical grinding device for pharmaceutical production and testing, comprising a housing, a top cover hinged to the top of the housing, a support foot fixedly connected to the bottom of the housing, a feed inlet at the top of the top cover, a grinding table fixedly connected to the bottom of the housing, a through groove inside the grinding table, a collection box movably connected to the bottom of the grinding table, a handle at the bottom of the front side of the housing, a control seat fixedly connected to the right side of the top of the top cover, a servo motor fixedly connected to the rear end of the housing, a movable shaft movably connected inside the housing, four sets of grinding rollers movably connected to the outside of the movable shaft, a connecting rod movably connected between the grinding rollers and the movable shaft, a liquid inlet on the left side of the housing, a liquid outlet on the right side of the housing, a cooling coil inside the grinding table, the liquid inlet, the liquid outlet, and the cooling coil being internally connected, and the cooling coil being evenly arranged inside the grinding table.

[0007] As a further technical solution of this utility model, the four sets of grinding rollers are distributed at equal angles, and the four sets of grinding rollers can rotate vertically on the outside of the movable shaft.

[0008] As a further technical solution of this utility model, the output of the servo motor is connected to the movable shaft, and the servo motor is electrically connected to the control base.

[0009] As a further technical solution of this utility model, the connecting rod is closely fitted with the grinding table, and the two sets of support legs are arranged symmetrically.

[0010] As a further technical solution of this utility model, a fixing ring is fixedly connected inside the box, a funnel is fixedly connected to the bottom end of the fixing ring, a screen is movably connected to the top end of the fixing ring, four sets of return springs are movably connected between the screen and the fixing ring, and two sets of electric telescopic rods are fixedly connected to the front and rear ends of the bottom side of the box.

[0011] As a further technical solution of this utility model, the output ends of the two sets of electric telescopic rods face the screen, the two sets of electric telescopic rods are electrically connected to the control seat, and the four sets of return springs are arranged symmetrically.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the drug grinding device for drug production and testing not only achieves the accuracy of drug testing, but also achieves drug screening and cooling of the ground drugs;

[0013] Equipped with a servo motor, movable shaft, grinding rollers, and connecting rods, the system operates by starting the servo motor after the medicine enters the grinding table. The servo motor drives the movable shaft to rotate, and four sets of grinding rollers are movably connected to the outside of the movable shaft. The grinding rollers fit tightly against the grinding table, thus grinding the medicine. The squeezing method between the grinding rollers and the grinding table effectively prevents the medicine from volatilizing due to cutting, thereby improving the accuracy of medicine testing. After the medicine is ground into powder, it enters the collection box through a trough, thus collecting the ground medicine for easy testing.

[0014] The device is equipped with a fixed ring, funnel, screen, return spring, and electric telescopic rod. When in use, the output ends of the two sets of electric telescopic rods are activated and strike the screen when they are stretched. The fixed ring is fixedly connected inside the box, and four sets of return springs are installed between the screen and the fixed ring. The up and down movement of the screen achieves the screening of medicines, thereby preventing large particles of medicines from entering the grinding table and affecting the grinding efficiency.

[0015] Equipped with an inlet, an outlet, and a cooling coil, the medicine is placed between the grinding table and the grinding rollers during use. When some medicines require long-term grinding, the grinding time is relatively long, and the medicine will be in a relatively high-temperature environment. High temperature may cause chemical degradation of the active ingredients in the medicine and reduce its efficacy. By injecting coolant into the inlet, the coolant is discharged from the outlet through the cooling coil, thereby cooling the grinding table and thus cooling down the medicine being ground.

[0023] The four sets of grinding rollers 12 are distributed at equal angles. The four sets of grinding rollers 12 can rotate vertically on the outside of the movable shaft 11. The output of the servo motor 10 is connected to the movable shaft 11. The servo motor 10 is electrically connected to the control base 9. The connecting rod 13 is tightly fitted to the grinding table 5. The two sets of support legs 3 are arranged symmetrically.

[0024] Specifically, such as Figure 1 and Figure 3As shown, during use, after the medicine enters the grinding table 5, the servo motor 10 is activated, which drives the rotation of the movable shaft 11. Four sets of grinding rollers 12 are movably connected to the outer side of the movable shaft 11. The grinding rollers 12 are in close contact with the grinding table 5, thereby achieving the grinding of the medicine. The squeezing method between the grinding rollers 12 and the grinding table 5 effectively prevents the medicine from evaporating due to cutting, thus improving the accuracy of medicine testing. After the medicine is ground into powder, it enters the collection box 7 through the trough 6, thereby collecting the ground medicine for easy testing.

[0025] The servo motor 10 is electrically connected to the control base 9. This technology is existing technology and will not be described in detail here.

[0026] A fixing ring 14 is fixedly connected inside the housing 1. A funnel 15 is fixedly connected to the bottom end of the fixing ring 14. A screen 16 is movably connected to the top end of the fixing ring 14. Four sets of return springs 17 are movably connected between the screen 16 and the fixing ring 14. Two sets of electric telescopic rods 18 are fixedly connected to the front and rear ends of the bottom side of the housing 1. The output ends of the two sets of electric telescopic rods 18 face the screen 16. The two sets of electric telescopic rods 18 are electrically connected to the control seat 9. The four sets of return springs 17 are arranged symmetrically.

[0027] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during use, by activating two sets of electric telescopic rods 18, the output ends of the two sets of electric telescopic rods 18 strike the screen 16 when stretched. A fixing ring 14 is fixedly connected inside the housing 1. Four sets of return springs 17 are installed between the screen 16 and the fixing ring 14. The up and down movement of the screen 16 achieves the screening of medicines, thereby preventing large particles of medicines from entering the grinding table 5 and affecting the grinding efficiency. The electric telescopic rods 18 are electrically connected to the control base 9. This technology is existing technology and will not be described in detail.

[0028] A liquid inlet 19 is provided on the left side of the housing 1, and a liquid outlet 20 is provided on the right side of the housing 1. A cooling coil 21 is provided inside the grinding table 5. The liquid inlet 19, the liquid outlet 20, and the cooling coil 21 are connected internally. The cooling coil 21 is evenly arranged inside the grinding table 5.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the medicine is placed between the grinding table 5 and the grinding roller 12. When some medicines need to be ground for a long time, the grinding time is relatively long, and the medicine will be in a relatively high temperature environment. High temperature may cause chemical degradation of the active ingredients in the medicine and reduce the efficacy. By injecting coolant into the inlet 19, the coolant is discharged from the outlet 20 through the cooling coil 21, thereby cooling the grinding table 5 and thus cooling down the medicine being ground.

[0030] Working Principle: In use, this invention firstly, after the medicine enters the grinding table 5, the servo motor 10 is activated. The servo motor drives the rotation of the movable shaft 11. Four sets of grinding rollers 12 are movably connected to the outer side of the movable shaft 11. The grinding rollers 12 are in close contact with the grinding table 5, thereby achieving grinding of the medicine. The squeezing method between the grinding rollers 12 and the grinding table 5 effectively avoids the volatilization of the medicine due to cutting, thus improving the accuracy of medicine testing. After the medicine is ground into powder, it enters the collection box 7 through the channel 6, thereby achieving the collection of the ground medicine and facilitating testing. Secondly, by activating two sets of electric telescopic rods 18, the output ends of the two sets of electric telescopic rods 18 strike the screen 16 when stretched. A fixing ring 14 is fixedly connected inside the housing 1. Four sets of return springs 17 are installed between the screen 16 and the fixing ring 14. The up and down movement of the screen 16 enables the screening of medicines, thereby preventing large particles of medicines from entering the grinding table 5 and affecting the grinding efficiency. At the same time, when the medicines are between the grinding table 5 and the grinding roller 12, some medicines need to be ground for a long time. The grinding time is long, and the medicines will be in a relatively high temperature environment. High temperature may cause chemical degradation of the active ingredients in the medicines, reducing the efficacy. By injecting coolant into the inlet 19, the coolant is discharged from the outlet 20 through the cooling coil 21, thereby cooling the grinding table 5 and thus cooling the grinding medicines.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
