Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical pulverization technology, specifically a pulverizing device for pharmaceutical manufacturing and processing. Background Technology

[0002] Medicines are substances that purposefully regulate human physiological functions and have specified indications or functions, usage and dosage. They include traditional Chinese medicine, chemical drugs and biological products. When processing medicines, pulverizing equipment is required for pulverization.

[0003] Chinese patent disclosure CN207756226U discloses a pulverizing and grinding device for pharmaceutical processing. The device includes a housing, with a top cover plate connected to the left side of the housing via a rotating hinge. A buckle is connected to the right side of the top cover plate, engaging with the housing. A motor base is fixedly connected to the rear top of the top cover plate, and a motor is fixedly connected above the motor base. A rotating disk is fixedly connected to the motor output end. A transmission rod is fixedly connected to the front of the rotating disk, perpendicularly connected to it. A through groove is formed in the center of the top of the top cover plate, through which a rotating grinding rod is rotatably connected via a rotating shaft. A transmission groove is formed at the top of the rotating grinding rod, engaging with the transmission rod. Compared with existing technologies, the advantages of this invention are: simple structure, convenient use, and the ability to adjust the grinding intensity during pharmaceutical processing to ensure sufficient immersion and avoid insufficient grinding, thus preventing the pharmaceutical pulverization from failing to meet requirements. This invention is worthy of promotion.

[0004] However, it still has the following drawbacks: the device uses a motor to drive the grinding roller to move left and right to pulverize the drugs in the grinding dish, but some drugs are submerged in powder, resulting in some drugs not being fully compressed, leading to poor pulverization effect. Therefore, we propose a pulverizing device for pharmaceutical manufacturing to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a pulverizing device for pharmaceutical manufacturing and processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pulverizing device for pharmaceutical manufacturing and processing, comprising a tank, wherein a pulverizing device is provided on the tank, and the pulverizing device includes a power unit;

The inner wall of the tank extends into the interior of the installation pipe and is slidably connected to the inner wall of the installation pipe. A double-headed motor is fixedly connected to the top surface of the tank.

[0008] The tank is equipped with a filter section inside.

[0009] The filter section includes a mounting plate, on which a sliding rod is slidably disposed through the upper and lower end faces, and a fixing block is fixedly connected to the bottom surface of the sliding rod.

[0010] A further improvement is that the power unit also includes a gear, a gear ring, a friction ring, a grinding block, a square rod, a screw, a sleeve, a first pulley, and a second pulley. The second pulley is fixedly sleeved on the outer surface of the top output shaft of the dual-head motor, and the first pulley is fixedly sleeved on the outer surface of the first rotating shaft. The outer surface of the top end of the square rod extends into the interior of the first rotating shaft and is slidably connected to the inner wall of the first rotating shaft. The outer surface of the grinding block is fixedly connected to the outer surface of the square rod, and the outer surface of the friction ring is fixedly connected to the inner wall of the mounting tube. By setting up a dual-head motor, a first rotating shaft, a square rod, a grinding block, and a friction ring, after starting the dual-head motor, the grinding block is driven to rotate, cooperating with the friction ring to grind the medicine.

[0011] A further improvement is that the outer surface of the bottom output shaft of the dual-head motor rotates through the top surface of the tank and extends into the inside of the tank via a bearing. The gear is fixedly sleeved on the outer surface of the bottom output shaft of the dual-head motor, and the gear ring is fixedly sleeved on the outer surface of the mounting tube. By controlling the rotation of the mounting tube and the friction ring through the gear and the gear ring, the relative rotation speed of the grinding block and the friction ring is increased, thereby increasing the grinding speed of the medicine.

[0012] A further improvement is that the screw's outer surface thread penetrates the top surface of the first rotating shaft and extends into the interior of the first rotating shaft. The bottom surface of the first rotating shaft is rotatably connected to the top surface of the square rod through a bearing seat. The sleeve is threaded onto the outer surface of the screw. By setting the screw, it is convenient to adjust the up and down movement of the grinding block and adjust the particle size of the medicine grinding.

[0013] A further improvement is that the filtration section also includes a filter screen, a baffle, a connecting rod, a protrusion, a spring, and a second rotating shaft. The outer surface of the filter screen is fixedly connected to the inner wall of the mounting plate, the outer surface of the fixing block is fixedly connected to the inner wall of the tank, and the bottom surface of the baffle is fixedly connected to the top surface of the mounting plate. By setting the filter screen, the medicine powder is ground.

By setting a filter screen, the drug powder is ground and sieved. By setting a protrusion and an abutting rod, the abutting rod impacts the protrusion, causing the filter screen to shake up and down, thereby improving the filtration speed of the drug.

[0015] A further improvement is that the bottom end of the spring is fixedly connected to the top surface of the fixed block, and the top end of the spring is fixedly connected to the inner wall of the mounting plate. By setting the spring, the mounting plate and the filter screen can be made to sway up and down, which promotes the screening of medicines.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This pulverizing device for pharmaceutical manufacturing and processing, by setting up a dual-head motor, gears, gear rings, mounting tubes, friction rings, grinding blocks, square rods, screws, sleeves, a first rotating shaft, a first pulley, and a second pulley, drives the friction ring and grinding block to rotate after the dual-head motor is started, thus grinding the pharmaceuticals. By rotating the screw, the square rod is adjusted to move downwards, reducing the distance between the grinding block and the friction ring below it, thereby reducing the particle size of the ground pharmaceuticals and improving the grinding effect. By setting up a filter screen and mounting plate, the filter screen is used to filter the pharmaceutical powder. By setting up a stop block, abutment rod, protrusion, sliding rod, spring, and fixing block, after the dual-head motor is driven, the abutment rod impacts the block, and the elastic force of the spring causes the mounting plate and filter screen to shake up and down, thereby increasing the filtration speed of the pharmaceutical powder by the device.
