Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a solid drug grinding device. Background Technology

[0002] In the analysis and testing of solid drugs, since the active ingredients in solid drugs may be unevenly distributed, in order to ensure the uniformity and representativeness of the sample, it is generally necessary to grind the drug into a fine powder first, mix it thoroughly, and then take a sample for dissolution analysis. Grinding can reduce sampling errors.

[0003] A solid drug grinding device, disclosed in CN218774867U, includes a machine body, grinding rollers, a gear pair, a grinding motor, a porous sieve plate, a U-shaped frame, a second drive motor, a turntable, a drive arm, and a telescopic spring. The machine body has a disassembly port and a single-opening door panel hinged to it. The U-shaped frame is installed inside the machine body at a position corresponding to the disassembly port, and a slot for accommodating the porous sieve plate is provided on the inner wall of the U-shaped frame. Two turntables are symmetrically distributed and rotatably mounted on the inner wall of the machine body via a rotating shaft. Through the cooperation of the second drive motor, the turntable, and the drive arm, the U-shaped frame can be driven to reciprocate vertically, thereby driving the porous sieve plate to reciprocate vertically, enabling reliable filtration of the ground drug. The porous sieve plate is also designed for easy installation, use, disassembly, and cleaning via the slot.

[0004] However, the patent still has the following problems in actual use: the device filters by oscillating the sieve plate. After the solid drug is ground, some solid drugs are not fully crushed and ground, which reduces the crushing and grinding effect. There will still be a small amount of solid drug clogging inside the sieve holes, which reduces the sieving and filtering effect and also reduces the grinding efficiency.

[0005] Therefore, a solid drug grinding device is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a solid drug grinding device to solve the problem that some solid drugs are not fully crushed and ground, resulting in a small amount of solid drugs clogging inside the sieve holes, thereby reducing the screening and filtration effect and the grinding efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a solid drug grinding device, comprising a housing and a base plate fixedly connected to the bottom of the housing, wherein support columns are fixedly installed around the bottom of the base plate; A door is hinged to one side of the front of the box, and a feeding port is fixedly installed on the top of the box; Also includes: A grinding assembly is provided at the upper part of the interior of the housing, the grinding assembly includes two grinding rollers rotatably mounted at the upper part of the interior of the housing, and an auxiliary assembly is provided at the lower part of the interior of the housing; The auxiliary component includes a sieve plate that is horizontally fixedly installed inside the box body. Two vertical grooves are opened on both sides of the box body. Sliding strips are slidably connected inside the vertical grooves. A connecting plate is fixedly connected to the side of the sliding strip near the sieve plate. A horizontal strip is fixedly connected in parallel between the two connecting plates. The screen plate has uniformly spaced screen holes inside, and the top of each crossbar is uniformly fixed with insert rods, the total number of which is the same as the number of screen holes.

[0008] Preferably, a slot is fixedly connected to one side of the inner wall of the box, and the sieve plate is engaged with the slot. Side guide strips are fixedly connected to both sides of the inner wall of the box, and the bottom surface of the side guide strips is in contact with the top surface of the sieve plate. The connecting plate is located inside the box.

[0009] Preferably, a sealing plate is fixedly connected to the top of the slide bar, the sealing plate is in contact with the vertical groove, the number of connecting plates is the same as the number of vertical grooves, the total number of horizontal bars is the same as the number of rows of sieve holes, and the insert rod is slidably connected to the sieve holes.

[0010] Preferably, linear guide rails are fixedly installed on both outer sides of the housing, and a movable seat is fixedly connected to the output end of the linear guide rails, with an inclined block fixedly connected to the top of the movable seat.

[0011] Preferably, the grinding assembly includes a first servo motor and a second servo motor fixedly installed on the upper side of one side of the housing. One first servo motor is provided, and guide plates are symmetrically fixedly connected to the upper part of the inside of the housing. Two second servo motors are provided.

[0012] Preferably, the output end of the first servo motor is fixedly connected to a stirring rod through the housing, and the output end of the second servo motor is fixedly connected to a grinding roller through the housing.

[0013] Preferably, a feed pipe is fixedly installed at the bottom of the box, and a guide frame is fixedly connected inside the box, with the guide frame located below the sieve plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting auxiliary components, the insert rod will intermittently insert into the sieve holes during the subsequent sieving of the ground solid drug, thereby reducing sieve hole clogging and improving the grinding effect of the solid drug without affecting the sieving of the solid drug. The specific details are as follows: 1. By setting auxiliary components, the crushed solid drug falls onto the top of the sieve plate. The operator activates the linear guide rail, which drives the moving seat to move linearly. The moving seat drives the inclined block to move, and the inclined block squeezes the slide bar, causing the slide bar to slide upward inside the vertical groove. The slide bar drives the connecting plate to move, and the connecting plate drives the sealing plate and the horizontal bar to move. The sealing plate seals the inside of the vertical groove, reducing leakage of solid drug from the vertical groove. The rising horizontal bar drives the insert rod to rise, and the insert rod inserts into the sieve holes of the sieve plate, facilitating the cleaning of the sieve holes and reducing clogging. The connecting plate is set in two parts, so that one part... While one part rises, the other part remains stationary, facilitating the sieving of the ground solid drug. The qualified solid drug falls to the bottom of the box and is discharged and collected through the feed pipe. When the inclined block separates from the slide bar, the weight of the crossbar and the insert rod will cause them to fall and reset. When the insert rod is inserted into the sieve hole, it will lift and disturb the solid drug on the top of the sieve plate, reducing the accumulation of solid drug and improving the sieving effect. This solves the problem that some solid drugs are not fully crushed and ground, and a small amount of solid drug will block the inside of the sieve hole, thereby reducing the sieving and filtering effect and the grinding efficiency. 2. By setting up the grinding components, the operator adds the solid drug to be ground into the box through the feeding port, and starts the first servo motor and the second servo motor respectively. The solid drug falls between the two grinding rollers after being guided by the guide plate. The second servo motor drives the grinding rollers to rotate, and the two grinding rollers grind the solid drug. The first servo motor also drives the stirring rod to rotate, and the stirring rod stirs the solid drug, which makes it easier for the solid drug to fully contact the grinding rollers for grinding, thus improving the grinding efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 8 The present invention provides a technical solution: a solid drug grinding device, comprising a box body 1 and a bottom plate 2 fixedly connected to the bottom of the box body 1, wherein support columns 3 are fixedly installed around the bottom of the bottom of the bottom plate 2.

[0019] A door 4 is hinged to one side of the front of the box 1, and a feeding port 5 is fixedly installed on the top of the box 1.

[0020] A grinding assembly 6 is provided on the upper part of the inside of the housing 1. The grinding assembly 6 includes two grinding rollers 65 that are rotatably installed on the upper part of the inside of the housing 1.

[0021] The grinding assembly 6 includes a first servo motor 61 and a second servo motor 64 fixedly installed on the upper side of one side of the housing 1. One first servo motor 61 is provided, and guide plates 63 are symmetrically fixedly connected to the upper part of the housing 1. Two second servo motors 64 are provided.

[0022] The output end of the first servo motor 61 passes through the housing 1 and is fixedly connected to the stirring rod 62. The output end of the second servo motor 64 passes through the housing 1 and is fixedly connected to the grinding roller 65.

[0023] The operator adds the solid drug to be ground into the housing 1 through the feeding port 5, and starts the first servo motor 61 and the second servo motor 64 respectively. The solid drug falls between the two grinding rollers 65 after being guided by the guide plate 63. The second servo motor 64 drives the grinding rollers 65 to rotate. The two grinding rollers 65 grind the solid drug, and the first servo motor 61 drives the stirring rod 62 to rotate. The stirring rod 62 stirs the solid drug, which makes it easier for the solid drug to fully contact the grinding rollers 65 for grinding, thus improving the grinding efficiency.

[0024] A feed pipe 8 is fixedly installed at the bottom of the box 1, and a guide frame 9 is fixedly connected inside the box 1. The guide frame 9 is located below the screen plate 72.

[0025] An auxiliary component 7 is provided at the bottom of the interior of the box 1. The auxiliary component 7 includes a sieve plate 72 that is horizontally fixed inside the box 1. Two vertical grooves 74 are opened on both sides of the box 1. A slide bar 75 is slidably connected inside the vertical groove 74. A connecting plate 76 is fixedly connected to the side of the slide bar 75 near the sieve plate 72. A horizontal bar 78 is fixedly connected in parallel between the two connecting plates 76.

[0026] A slot 71 is fixedly connected to one side of the inner wall of the box 1. The sieve plate 72 is engaged with the slot 71. Side guide strips 73 are fixedly connected to both sides of the inner wall of the box 1. The bottom surface of the side guide strip 73 is in contact with the top surface of the sieve plate 72. The connecting plate 76 is located inside the box 1.

[0027] The sieve plate 72 has sieve holes evenly spaced inside, and the top of the crossbar 78 is evenly fixed with insert rods 79, the total number of insert rods 79 being the same as the number of sieve holes.

[0028] A sealing plate 77 is fixedly connected to the top of the slide bar 75. The sealing plate 77 fits into the vertical groove 74. The number of connecting plates 76 is the same as that of the vertical groove 74. The total number of horizontal bars 78 is the same as the number of rows of screen holes. The insert rod 79 is slidably connected to the screen holes.

[0029] The crushed solid drug falls onto the top of the sieve plate 72. The operator activates the linear guide rail 710, which drives the moving seat 711 to move linearly. The moving seat 711 drives the inclined block 712 to move, and the inclined block 712 squeezes the slide bar 75, causing the slide bar 75 to slide upward inside the vertical groove 74. The slide bar 75 drives the connecting plate 76 to move, and the connecting plate 76 drives the sealing plate 77 and the horizontal bar 78 to move. The sealing plate 77 seals the inside of the vertical groove 74, reducing the leakage of solid drug from the vertical groove 74. The horizontal bar 78 rises, causing the insertion rod 79 to rise. The insertion rod 79 is inserted into the sieve hole of the sieve plate 72, which facilitates the cleaning of the sieve hole of the sieve plate 72 and reduces the clogging of the sieve hole.

[0030] Furthermore, the connecting plate 76 is configured in two parts, so that when one part rises, the other part remains stationary, which facilitates the sieving of the ground solid drug. After sieving, the qualified solid drug falls into the bottom of the box 1 and is discharged and collected through the discharge pipe 8. When the inclined block 712 separates from the slide bar 75, the weight of the cross bar 78 and the insertion rod 79 will cause them to fall and reset. When the insertion rod 79 is inserted into the sieve hole, it will lift and disturb the solid drug on the top of the sieve plate 72, reduce the accumulation of solid drug, and improve the sieving effect.

[0031] Linear guide rails 710 are fixedly installed on both sides of the outer side of the housing 1. A movable seat 711 is fixedly connected to the output end of the linear guide rail 710. An inclined block 712 is fixedly connected to the top of the movable seat 711.

[0032] Working principle: Before using this solid drug grinding device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 8 As shown, the operator adds the solid drug to be ground into the housing 1 through the feeding port 5, and starts the first servo motor 61 and the second servo motor 64 respectively. The two grinding rollers 65 grind the solid drug, and the stirring rod 62 stirs the solid drug to ensure that the solid drug fully contacts the grinding rollers 65 for grinding. The crushed solid drug falls to the top of the sieve plate 72. The operator starts the linear guide rail 710, which drives the moving seat 711 to move linearly. The moving seat 711 drives the inclined block 712 to move. The inclined block 712 squeezes the slide bar 75, causing the slide bar 75 to move inside the vertical groove 74. The slide bar 75 moves the connecting plate 76, which in turn moves the sealing plate 77 and the horizontal bar 78. The sealing plate 77 seals the inside of the vertical groove 74, reducing leakage of solid drugs from the vertical groove 74. The horizontal bar 78 rises, causing the insertion rod 79 to rise. The insertion rod 79 is inserted into the sieve hole of the sieve plate 72, which facilitates cleaning of the sieve hole and reduces clogging. The connecting plate 76 is set in two parts, so that when one part rises, the other part does not move, which facilitates the sieving of the other part of the ground solid drugs. The qualified solid drugs after sieving fall into the bottom of the box 1 and are discharged and collected through the discharge pipe 8.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
