Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of smashing and mixing, particularly relates to a smashing and mixing machine with screening function. BACKGROUND

[0002] In traditional Chinese medicinal material production and processing enterprises, various raw materials of traditional Chinese medicinal materials need to be smashed and processed frequently to facilitate the continuous processing of the following processing procedures, and the ordinary traditional Chinese medicinal material smashing device used by the pharmaceutical enterprises has long smashing time, low production efficiency and cannot better meet the processing needs of the pharmaceutical enterprises.Meanwhile, when the crushed traditional Chinese medicinal materials are screened, a long time is needed, a large amount of human resources is consumed and the screening effect is poor, the existing screening devices all use single filter screens for screening, the filter screen screening belongs to static screening, the filter screen is prone to accumulation, leading to low screening efficiency, therefore, an automatic screening device for crushed traditional Chinese medicinal materials and a screening device with short time consumption need to be developed urgently.

[0003] Traditional Chinese medicine (TCM-Traditional Chinese Medicine or "Traditional Chinese Medicine") refers to natural drugs and their processed substitutes for preventing and treating diseases and having rehabilitation and health care effects under the guidance of traditional Chinese medicine theory, which has a unique theoretical system and application form, mainly including plant medicines, animal medicines and mineral medicines, and smashing is one of the basic operation units in the processing of traditional Chinese medicinal materials, through smashing, the surface area of the drugs can be increased, the dissolution and absorption of the drugs can be promoted, and the leaching of the effective components in the medicinal materials can be accelerated, so some traditional Chinese medicinal materials need to be smashed, mechanical smashing is adopted, and a large amount of medicinal materials can be smashed quickly.

[0004] Existing Chinese medicine (TCM) manufacturers often encounter problems with their pulverizing equipment when processing various raw TCM herbs, such as long pulverizing times, low production efficiency, and inability to adequately meet the processing needs of pharmaceutical companies. For example, a TCM pulverizing and mixing device, patent number CN201820093316.3, discloses a device comprising a pulverizing shell and a Y355 motor, wherein the Y355 motor is perpendicularly arranged to the pulverizing shell, the surface of the pulverizing shell has a power inlet embedded therein, a control switch is located on the side of the power inlet and is embedded therein and electrically connected to the power inlet, and the bottom of the Y355 motor has several support frames. This TCM pulverizing and mixing device, through a sieve plate installed inside the pulverizing shell, can screen out large pieces of herbs after pulverization, achieving a screening effect. This avoids the need for workers to perform an additional screening step to remove large pieces of medicinal herbs. The vibrator, working in conjunction with the sieve plate, causes the sieve plate to shake, accelerating the removal of large pieces and saving operator time, thus improving efficiency. While the above structure can achieve the pulverization and screening of Chinese medicinal materials, the pulverization process, being a single, reverse-direction operation, can easily lead to incomplete pulverization and poor results. Furthermore, since multiple medicinal materials need to be pulverized during preparation, and then uniformly mixed, this equipment is not ideal for mixing multiple pulverized medicinal materials.

[0005] To address the aforementioned issues, we provide a pulverizing and mixing machine with a screening function that can more efficiently pulverize Chinese medicinal herbs, screen them, and mix the pulverized materials. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a crushing and mixing machine with screening function.

[0007] The purpose of this utility model is achieved as follows: a crushing and mixing machine with screening function includes a lower box, an upper box above the lower box, a crushing mechanism inside the upper box, a cover plate at the top of the upper box, a feed inlet on the cover plate, a screen inside the lower box; a discharge port is opened on the side of the lower box, and a discharge pipe is provided at the discharge port.

[0008] Furthermore, the crushing mechanism includes an inner rotating shaft and an outer rotating shaft. The inner rotating shaft is rotatably located inside the outer rotating shaft, and the upper and lower ends of the inner rotating shaft rotatably pass through the outer rotating shaft. A lower crushing blade is provided at the lower end of the inner rotating shaft, and an upper crushing blade is provided at the lower end of the outer rotating shaft.

[0009] Furthermore, the outer and inner rotating shafts are rotatably located within the upper housing.

[0010] Further, the inner rotating shaft and the upper part of the outer rotating shaft are provided with a driving mechanism one, which drives the inner rotating shaft and the outer rotating shaft to rotate.

[0011] When the utility model is used, the material (for example, traditional Chinese medicinal materials and the like) to be crushed is added into the upper box through the feeding hopper, the controller controls the driving motor one and the driving motor two to rotate, and the driving motor one drives the inner rotating shaft and the outer rotating shaft to rotate when rotating. That is, the driving motor one drives the inner rotating shaft to rotate, and simultaneously drives the outer rotating shaft and the inner rotating shaft to rotate in the opposite direction through the transmission of the gear one, the gear two, the gear three, the gear four and the gear five); the upper crushing knife and the lower crushing knife are driven to rotate when the inner rotating shaft and the outer rotating shaft rotate, so that the crushing and cutting of the material are realized; the crushing and cutting of the material can be better realized through the opposite rotation of the upper crushing knife and the lower crushing knife, because the material moves in the opposite direction around the upper crushing knife when the material is crushed by the upper crushing knife, if the lower crushing knife and the upper crushing knife rotate in the same direction, the material will directly fall into the lower crushing knife, which will result in poor crushing effect; the crushed material falls on the screen, the screen is uniformly provided with screen holes (the size of the screen hole can be set according to the requirement), the driving motor two is controlled to rotate through the controller, and the screen is driven to rotate, so that the material on the screen can roll, and the efficiency of the material falling into the lower box can be increased, and the particles that do not meet the size can be filtered out.

[0012] When the material filtered by the screen enters the lower box, the transmission shaft drives the stirring fan blade to rotate, so that the material in the lower box can be fully mixed (because different materials can be crushed when the material is crushed, the material can be more uniformly mixed through the stirring fan blade in the lower box, so that the subsequent process can be produced); the mixed material in the lower box is discharged through the discharge pipe.

[0013] Advantages: the application can realize the crushing of the material, the cutting and crushing mode of the opposite rotation of the upper crushing knife and the lower crushing knife can improve the crushing effect of the material, the screen that can rotate can increase the screening efficiency of the material; and the material can be fully mixed and stirred.
