Description

Technical Field

[0001] The utility model belongs to the field of pharmaceutical detection experimental equipment, and particularly relates to a grinder for a pharmaceutical detection laboratory. Background Art

[0002] In a pharmaceutical detection laboratory, fine grinding of medicinal materials is a basic step in research work such as drug component analysis, quality control, and new drug research and development. Traditional methods of grinding medicinal materials often rely on manual labor or simple mechanical equipment. These methods have problems such as low grinding efficiency, uneven powder particle size, cumbersome operation, and easy contamination. Especially for medicinal materials with high hardness or specific particle size requirements, traditional methods are difficult to meet the strict standards for powder quality in the laboratory.

[0003] A Chinese patent with the publication number CN215963862U discloses a grinder for a pharmaceutical detection laboratory, which includes a grinding motor and a grinding wheel. The output end of the grinding motor is connected to the grinding wheel. It also includes a handheld handle and a hand pressure handle. The ends of the handheld handle and the hand pressure handle are hinged. A grinding groove is provided in the middle of the handheld handle. A grinding mechanism is installed on the hand pressure handle. The grinding mechanism is matched with the position of the grinding groove. The grinding mechanism includes a sealing cover, an installation box, a grinding motor, and a grinding wheel. The installation box is connected to the hand pressure handle, and a sealing cover is provided at the lower end of the installation box. The advantages are that the hinged handheld handle and hand pressure handle are beneficial for hand-held extrusion during the grinding process, so that the grinding wheel and the rough bottom layer approach each other to increase the grinding effect. Since there is a detachable grinding groove, it is beneficial to place the test sample in the grinding groove and also beneficial to pour out the ground powder.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1 to 4 shown:

[0022] Embodiment 1: The present utility model provides a grinder for a pharmaceutical testing laboratory, including: a collection mechanism 1, including a machine housing assembly 11 and a collection cup 12 clamped on the machine housing assembly 11; a grinding mechanism 2, including a primary grinding assembly 21 and a secondary grinding assembly 22 installed on the machine housing assembly 11, and the primary grinding assembly 21 can drive the secondary grinding assembly 22 to rotate.

[0023] Specifically, the casing assembly 11 includes a casing body 111. Inside the casing body 111, a grinding sieve 112 is fixedly connected. The grinding sieve 112 divides the interior of the casing body 111 into an upper chamber and a lower chamber. The bottom of the lower chamber is an inclined surface. On one side of the outside of the casing body 111, a discharge port 113 is fixedly connected. The discharge port 113 communicates with the lower chamber. On the other side of the outside of the casing body 111, a handle 114 is fixedly connected. At the top of the casing body 111, a feed port 115 is fixedly communicated. At the bottom of the casing body 111, a base 116 is fixedly connected.

[0024] Specifically, the collection cup 12 is snap-fitted on the top of the base 116.

[0025] Specifically, the preliminary grinding assembly 21 includes a motor 211 fixedly connected to the outside of the casing body 111. The output end of the motor 211 extends into the interior of the casing body 111 and is fixedly connected to one end of a first rotating shaft 212. The other end of the first rotating shaft 212 penetrates the casing body 111 and is fixedly connected to a first pulley 213. On the outside of the first rotating shaft 212 and located outside the casing body 111, a driving gear 214 is fixedly connected. On the outside of the first rotating shaft 212 and located in the upper chamber of the casing body 111, a first rolling roller 215 is fixedly connected. Inside the casing body 111, one end of a second rotating shaft 216 is also fixedly connected through a bearing. The other end of the second rotating shaft 216 extends outside the casing body 111 and is fixedly connected to a driven gear 217. On the outside of the second rotating shaft 216 and located in the upper chamber of the casing body 111, a second rolling roller 218 is fixedly connected. The driven gear 217 meshes with the driving gear 214.

[0026] As can be seen from the above, during use, the device can be moved to a specified position for use by holding the handle 114. Turn on the motor 211 to make the first rotating shaft 212 rotate. The first rotating shaft 212 drives the first rolling roller 215, the driving gear 214, and the first pulley 213 to rotate. The driving gear 214 drives the driven gear 217 to rotate. The driven gear 217 drives the second rotating shaft 216 and the second rolling roller 218 to rotate. The first pulley 213 drives the secondary grinding assembly 22 to rotate. At this time, the drug is injected into the upper chamber of the casing body 111 through the feed port 115 and is preliminarily ground by the second rolling roller 218 and the first rolling roller 215, and then falls onto the grinding sieve 112 and is ground again by the secondary grinding assembly 22, which improves the grinding efficiency and the fineness of the powder, meets the high requirements of the pharmaceutical testing laboratory for the particle size of the medicinal material powder. The ground powder falls into the lower chamber of the casing body 111 and is guided by its inclined surface, so that the powder falls into the collection cup 12 through the discharge port 113, realizing the automatic collection and centralized processing of the powder, which is convenient for subsequent pharmaceutical testing work.

[0027] Embodiment 2: This embodiment is basically the same as the previous one, except that the secondary grinding assembly 22 includes a third rotating shaft 221 located on the lower side of the first rolling roller 215 and the second rolling roller 218. One end of the third rotating shaft 221 is fixedly connected to the inner side wall of the machine housing body 111 through a bearing. The other end of the third rotating shaft 221 extends to the outside of the machine housing body 111 and is fixedly connected with a second pulley 222. A plurality of grinding blocks 223 are fixedly connected to the outside of the third rotating shaft 221.

[0028] Specifically, a belt 224 is jointly sleeved outside the first pulley 213 and the second pulley 222.

[0029] As can be seen from the above, when the first pulley 213 rotates, the second pulley 222 is driven to rotate through the arrangement of the belt 224. The second pulley 222 drives the third rotating shaft 221 to rotate, and the third rotating shaft 221 drives the grinding blocks 223 to rotate. The rotation of the grinding blocks 223 causes the medicine to be further ground into powder and fall into the lower chamber of the machine housing body 111.

[0030] The embodiments of the present utility model are given for the purpose of illustration and description. Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations of the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
