The Chinese medicinal material cutting device is mainly suitable for cutting Chinese medicinal materials. The traditional Chinese medicinal material processing method often has shortcomings in the screening link, and it is impossible to effectively remove impurities and accurately sort out high-quality medicinal materials.

[0046] When the medicine cutting device is used, first start the feeder 2 and the medicine cutting motor 43, and then place the Chinese medicinal materials to be cut on the surface of the feeder 2. Through the operation of the medicine cutting motor 43, the driving gear 44 can be driven to rotate inside the support seat 42, and then the driven gear 1 45 and the driven gear 2 415 on both sides thereof are respectively driven to rotate. With the rotation of the driven gear 1 45, the driven shaft 1 46 can be driven to rotate inside the support seat 42, thereby driving the eccentric rod 1 47 to rotate, and then the rotation of the eccentric rod 1 47 can drive the swing rod 1 48 to rotate, and then drive the connecting rod 49 to reciprocate up and down under the fixed frame 41, which can drive the lifting column 410 to rotate on the fixed frame 41.

With the movement of the lifting column 410, the pressure plate 412 can be driven to slide synchronously inside the limiting sleeve 411, and the squeezing spring 413 is deformed to generate elastic force, which can drive the pressure roller 414 to approach the surface of the feeder 2. When the Chinese medicinal materials are transported to the bottom of the pressure roller 414, the squeezing of the Chinese medicinal materials by the pressure roller 414 can ensure the subsequent cutting accuracy, so that the Chinese medicinal materials can maintain a stable position when cutting, and ensure that the size of the medicinal materials after cutting is more accurate and consistent, thereby preventing the Chinese medicinal materials from deviating, and can make the Chinese medicinal materials be cut into regular shapes. Due to the accurate cutting position, the generation of waste caused by deviation is reduced.

[0047] It is worth noting that, through the rotation of the driven gear 415, the driven shaft 416 can be driven to rotate synchronously, and then the eccentric rod 417 can be driven to rotate, so that the swing rod 418 can be pushed up and down to move in the avoidance groove opened inside the fixed frame 41 and the first fixed seat 21, and then the movement of the swing rod 418 can push one end of the medicine cutting tool 419 to make it flip around one end of the hinged seat 420. When the Chinese medicinal materials are transported to the bottom of the medicine cutting tool 419, the movement of the medicine cutting tool 419 can complete the cutting process of the Chinese medicinal materials, and when the medicine cutting tool 419 is cutting, the pressing roller 414 can press Press on the surface of the Chinese medicinal materials and cut them under the compacted state. The cuts of the Chinese medicinal materials will be more neat, reducing the generation of breakage and burrs, making the size of the Chinese medicinal materials more accurate and uniform, avoiding the loss and damage of ingredients caused by irregular cutting, thereby ensuring the efficacy of the Chinese medicinal materials, and making the Chinese medicinal materials stable during the cutting process, reducing the risk of shaking and splashing, reducing the safety hazards to operators, and also protecting the safety of production equipment, greatly reducing the generation of defective products, and reducing the scrap rate. At the same time, regular cutting sizes can reduce blockages during transportation and processing, ensuring the smooth flow of the production line, and improving the reliability and safety of production.

[0048] Furthermore, the cut Chinese medicinal materials can fall from the feed port opened on the top of the screening box 1 to the surface of the screening net 310 under the continuous conveyance of the feeder 2. At this time, by starting the screening motor 32, the worm gear 33 can drive the drive shaft 34 to rotate on the surface of the fixed plate 31, thereby driving the swing parts 35 at both ends to rotate synchronously, thereby driving the reciprocating rocker arm 36 to reciprocate on the surface of the fixed plate 31, and driving the push-pull rod 37 to slide back and forth inside the limit seat 38. Through the reciprocating sliding of the push-pull rod 37, it can The screening frame 39 at one end is driven to move back and forth synchronously along the surface of the positioning wheel 315 and the support frame 314 inside the screening box 1. The movement of the screening frame 39 can drive the fixed ears 316 on both sides of its surface to slide in the give way grooves opened inside the screening box 1, thereby driving the cable 317 to slide along the surface of the reversing wheel 318, and driving the fixed ears 316 fixed at the other end of the cable 317 to slide relatively inside the screening box 1, thereby driving another set of screening frames 39 inside the screening box 1 along the positioning wheel 315 The surface of the support frame 314 can be reciprocated synchronously, and the screening net 1 310 and the screening net 2 311 can be driven to reciprocate inside the screening box 1 respectively, so as to screen the fallen Chinese medicinal materials. During this period, the movement of the screening net 1 310 can effectively separate unqualified broken materials, leaving only qualified Chinese medicinal materials, thereby greatly improving the purity of the Chinese medicinal materials. The movement of the screening net 2 311 can perform secondary screening on the Chinese medicinal materials screened for the first time, thereby improving the screening effect. After the secondary screening of the screening net 2 311, the second screening net 311 can be used to screen the Chinese medicinal materials. The impurities after the first screening will fall on the surface of the impurity remover 313. Through the operation of the impurity remover 313, the impurities that can fall are sent out of the screening box 1, so as to select the high-quality parts. The Chinese medicinal materials can be divided into different grades through multi-layer screening, and the medicinal materials with relatively high content of effective ingredients can be accurately selected, which is helpful to establish a unified quality standard so that each batch of Chinese medicinal materials has a more consistent quality. After screening, the quality of qualified Chinese medicinal materials is more stable, which means that each batch of Chinese medicinal materials can maintain a high consistency in efficacy.

[0049] Furthermore, as the screening process proceeds, the amount of Chinese medicinal materials accumulated on the surfaces of the first screening net 310 and the second screening net 311 will gradually increase, thereby increasing the gravity borne by the first screening net 310 and the second screening net 311, and causing the first screening net 310 and the second screening net 311 to move downward inside the screening frame 39, thereby pressing the first spring 58 downward to deform and generate elastic force, thereby squeezing the first pressure sensor 59 to generate a pressure point signal. When the pressure point signal generated by the first pressure sensor 59 reaches a set threshold, , the discharging motor 52 can be automatically started to drive the discharging screw rod 51 at the output end of the screening motor 32 to rotate on the surface of the screening box 1, and then, with the cooperation of the chain 53, another set of discharging screw rods 51 can be driven to rotate synchronously on the surface of the screening box 1, thereby driving the two sets of moving plates 54 to slide in the moving grooves opened inside the screening box 1, and then driving the moving frame 55 to slide synchronously inside the screening box 1, and slide along the pushing groove opened inside the screening frame 39, thereby driving the pushing plate 56 and the first cleaning brush 5 7 slides synchronously along the surface of the screening net 1 310, and through the movement of the pushing plate 56, the Chinese medicinal materials accumulated on the surfaces of the screening net 1 310 and the screening net 2 311 can be pushed until the Chinese medicinal materials are pushed to the position of the first blocking plate 510. Under the action of the squeezing force, the first blocking plate 510 is forced to slide inside the screening frame 39, squeezing the first spring 3 513 to deform and generate elastic force, thereby driving the first positioning rod 514 to slide inside the first blocking frame 512 until the first blocking plate 510 is pushed to the position of the first blocking plate 510. The plate 510 is pushed out of the screening frame 39. At this time, the Chinese medicine that has lost its obstruction will fall from the surface of the screening net 1 310 and the screening net 2 311 into the corresponding discharge hopper 312 respectively, and finally be discharged from the discharge hopper 312 respectively, to avoid the accumulation of Chinese medicine on the surface of the screen. Pushing it out in time can greatly shorten the discharge time and reduce the burden on the screen. The accumulated Chinese medicine will increase the load of the screen, which may cause deformation and damage to the screen in the long run. Pushing it out in time can reduce the burden on the screen and extend the service life of the screen.

[0050] It is worth noting that during the movement of the mobile frame 55, the two groups of first cleaning brushes 57 can be driven to slide along the surfaces of the screening net 1 310 and the screening net 2 311 respectively, so as to clean the surfaces of the screening net 1 310 and the screening net 2 311, thereby avoiding the accumulation of Chinese medicinal materials on the surfaces of the screening net 1 310 and the screening net 2 311 and causing blockage, so that the screening net 1 310 and the screening net 2 311 maintain good screening performance, ensure that the Chinese medicinal materials can pass through the sieve holes evenly during the screening process, avoid uneven screening due to blockage, ensure the normal operation of the screening equipment, and avoid frequent shutdowns for cleaning due to blockage, thereby ensuring the continuity and stability of production, helping to realize automated production, reduce the frequency of manual intervention, and improve production efficiency. By automatically cleaning the screen when pushing the material, the workload and time cost of manual cleaning of the screen can be reduced.
