Description

Technical Field

[0001] This invention relates to the field of medicinal material processing technology, and in particular to a medicinal material processing apparatus. Background Technology

[0002] Chinese medicinal materials refer to medicinal materials produced in a specific region with specific natural conditions and ecological environment. Because the production is relatively concentrated, the cultivation techniques, harvesting and processing are also quite particular, resulting in better quality and efficacy compared to the same medicinal materials produced in other regions. In order to facilitate the storage and transportation of medicinal materials, Chinese medicinal materials or Chinese medicinal decoction pieces need to be sliced ​​and cut into slices of different thicknesses and sizes as needed.

[0003] According to the invention patent CN118952344A, an adjustable slicing device for processing Chinese medicinal materials includes two support plates. Each support plate has a fixed base for placing Chinese medicinal materials on one side closest to it. The base is equipped with a driving and pushing component to advance the Chinese medicinal materials. A blocking component connected to the base is located on one side of the driving and pushing component to limit one end of the Chinese medicinal materials. Below the driving and pushing component is a receiving and screening component connected to the base. The driving and pushing component drives the receiving and screening component to vibrate and screen the sliced ​​Chinese medicinal materials. This invention not only facilitates automatic slicing of medicinal materials but also slices two medicinal materials simultaneously, improving slicing efficiency. Furthermore, the slicing process involves the scattering of the sliced ​​materials upon falling, along with vibration screening, which helps to quickly remove and separate debris.

[0004] While the aforementioned technical solution can achieve the slicing of root and rhizome medicinal materials, its dual-axis motor drives the pusher assembly and cutter synchronously during operation. Therefore, it cannot adjust the slice size. Secondly, the pressure roller cannot be adjusted vertically, which means that when the medicinal material is large, it may have difficulty passing under the pressure roller, or even be crushed. Furthermore, slicing by the rotating cutter causes the slices to scatter everywhere, failing to achieve the effect of allowing the medicinal material to fall automatically. Unless the dual-axis motor rotates at a slower speed, it will affect the processing efficiency of the medicinal materials, thus limiting its applicability. Summary of the Invention

[0005] The purpose of this invention is to provide a medicinal material processing device that can process root and rhizome medicinal materials. When fixing root and rhizome medicinal materials, it is not only not limited by the size of the medicinal materials to avoid breakage, but also can adjust the size of the slices.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A medicinal herb processing device includes a support frame. Several conveying rollers arranged along the length of the support frame are rotatably connected to the left and right sides of the upper inner wall of the support frame. Baffles are provided on both sides of the conveying rollers along the length of the upper end of the support frame. The inner walls of two baffles are respectively provided with first sliding grooves arranged along the length of the baffles. A pushing assembly is slidably connected between the two first sliding grooves. An electric push rod is installed between the rear end of the outer wall of the pushing assembly and the rear end of the inner wall of the support frame. Sliding rods are arranged opposite each other on the front ends of the left and right sides of the upper end of the support frame. A limit rod is provided between the upper ends of the outer walls of two sliding rods. A connecting rod that slides along the length of the two sliding rods is slidably connected between the outer walls of the two sliding rods. A slicing blade is provided at the lower end of the connecting rod. The upper end of the support frame has a downward-facing groove below the slicing blade to cooperate with it. The front end of the outer wall of the support frame has a groove communicating with the groove. The rear end of the outer wall of the connecting rod is provided with a pressing component. A drive motor is installed on one side of the upper end of the outer wall of the limiting rod. A drive disc is provided on the outer wall of the drive motor's power output shaft. A rocker arm is rotatably connected between the eccentric part of the drive disc and one end of the outer wall of the connecting rod. Positioning scales are provided on both the left and right sides of the front end of the outer wall of the support frame. An adjustment component that slides along the length direction is slidably connected to the outer walls of the two positioning scales. The front end of the support frame is rotatably connected to a screening component that can rotate back and forth below the slot. A wedge-shaped guide rod is vertically arranged on the other side of the outer wall of the connecting rod, and a wedge-shaped fixing block is arranged on one side of the outer wall of the screening component, which cooperates with the lower end of the guide rod. A conical guide hopper is arranged in the support frame between the screening component and the knife slot. A control panel is arranged at the rear end of the outer wall of the support frame. The electric push rod, the drive motor and the adjustment component are all electrically connected to the control panel.

[0007] By adopting the above technical solution, when using the device, first move it to the corresponding position and fix it, then turn it on, place the medicinal material to be sliced ​​on the conveyor roller on the support frame, then fix the rear end of the root and stem medicinal material to be sliced ​​by the pushing component, then slide the adjustment component on the positioning scale to control the size of the slice, then operate the control panel to make the electric push rod, drive motor and adjustment component work. The electric push rod pushes the medicinal material towards the blade groove through the pushing component. When the front end of the medicinal material contacts the rear end of the adjustment component, the drive motor on the limit rod starts to work and drives the drive disk to rotate. The drive disk drives the connecting rod to slide up and down along the outer wall of the slide rod through the rocker arm. When the connecting rod slides down, the lower end of the pressing component will first contact the outer wall of the medicinal material to fix the front end of the medicinal material. Next, the connecting rod continues to slide downwards, allowing the slicing blade to slice the medicinal material and pass it through the lower end of the blade groove. The sliced ​​medicinal material will then fall into the screening component through the guide hopper for screening. Afterwards, the rotating disc drives the connecting rod to slide upwards, and then the electric push rod extends again to push the medicinal material forward. This process is repeated to achieve continuous slicing of the medicinal material. When the connecting rod slides down, the guide rod will contact the front end of the fixed block and cause the screening component to sway back and forth to improve the screening effect of the sliced ​​medicinal material.

[0008] A further embodiment of the present invention is provided that the pushing assembly includes a slider with a front opening, a second sliding groove formed on the left and right sides of the inner wall of the slider, a pressure plate slidably connected to the second sliding groove, a pull rod disposed on the upper end of the outer wall of the pressure plate and extending out of the upper end of the outer wall of the slider and slidably connected thereto, and a first return spring disposed between the upper end of the outer wall of the pressure plate and the upper end of the inner wall of the slider and sleeved on the outer wall of the pull rod.

[0009] By adopting the above technical solution, the rear end of the medicinal material can be fixed when placing it, thereby improving the stability during the process of pushing the medicinal material to slice.

[0010] A further embodiment of the present invention is that the pressing assembly includes a hollow housing, a plurality of sliding holes equally spaced at the bottom of the housing, a plurality of pressing rods corresponding to and slidably connected to the sliding holes, a plurality of pressing blocks respectively disposed at the lower ends of the pressing rods, and a plurality of second return springs respectively disposed between the upper ends of the pressing rods and the upper ends of the inner walls of the housing.

[0011] By adopting the above technical solution, not only can the medicinal materials be fixed during slicing, but the fixing can also be carried out according to the thickness of the roots and stems of different medicinal materials. The fixing is more convenient and flexible, and the medicinal materials will not be crushed.

[0012] A further feature of the present invention is that: a positioning hole is provided at the upper end of the outer wall of each pressing rod, and a plurality of positioning rods corresponding to the pressing rods and extending into the corresponding positioning holes are provided at the upper end of the inner wall of the housing, and each second reset spring is sleeved on the outer wall of the corresponding positioning rod.

[0013] By adopting the above technical solution, the smoothness of the pressing rod sliding inside the housing can be improved, and jamming can be avoided.

[0014] A further configuration of the present invention is as follows: the adjustment assembly includes a T-shaped fixed rod, through holes opened on the left and right sides of the front end of the outer wall of the fixed rod, threaded holes opened on the left and right sides of the outer wall of the fixed rod and communicating with the corresponding through holes, fixed bolts threadedly connected to the threaded holes, a plurality of pressure sensors installed on the rear end of the outer wall of the fixed rod, and baffles configured to cooperate with the rear end of the pressure sensors.

[0015] A further configuration of the present invention is as follows: the screening assembly includes a U-shaped fixed frame, a plurality of screens arranged along the height direction of the fixed frame and all inclined downward from front to back, and rocker arms rotatably connected between the front and rear ends of the left and right sides of the outer wall of the fixed frame, wherein the diameter of the screen holes of the screens increases sequentially from bottom to top.

[0016] By adopting the above technical solution, sliced ​​medicinal materials can be screened at different levels, reducing subsequent operations and alleviating the labor intensity of staff.

[0017] A further feature of the present invention is that the rear ends of the left and right sides of the inner wall of the fixed frame are inclined downward at the lower end of each screen and are provided with guide plates extending out of their opening ends, and the length of the guide plates extending out of the rear end of the fixed frame increases sequentially from bottom to top.

[0018] By adopting the above technical solution, it is easier for staff to collect the sieved medicinal material slices from different levels.

[0019] A further feature of the present invention is that a roller is rotatably connected to the front end of the outer wall of the fixed block.

[0020] By adopting the above technical solution, the smoothness of contact between the guide rod and the fixed block can be improved, friction can be reduced, and the service life can be increased.

[0021] A further provision of the present invention is that a partition plate is provided at the upper end of the inner wall of the support frame, below the conveying roller, and inclined downward from front to back to cooperate with it.

[0022] By adopting the above technical solution, it is possible to prevent medicinal material residue from falling into the screening assembly and onto the ground through the gaps between the conveying rollers during the conveying of medicinal materials, thereby reducing the labor intensity of subsequent cleaning by the staff.

[0023] In summary, the present invention has the following beneficial effects: Firstly, this invention can process root and rhizome medicinal materials. When fixing the medicinal materials, it is not only not limited by the size of the root and rhizome medicinal materials to avoid breaking the materials, but also can adjust the size of the slices. Secondly, this invention can achieve the effect of slicing medicinal materials and sieving the medicinal material slices by driving the sieving component to shake through a single drive motor. Thirdly, the pressing component of the present invention can not only fix the medicinal materials to facilitate the slicing process, but also fix the root and stem medicinal materials of different thicknesses and sizes, making it more flexible and convenient to use.

[0029] An electric push rod 2 for driving the slider 15 to slide back and forth is installed between the rear end of the outer wall of the slider 15 and the rear end of the inner wall of the support frame 1. A sliding rod 21 is arranged opposite to the front ends of the left and right sides of the upper end of the support frame 1. A limiting rod 22 is arranged between the upper ends of the outer walls of the two sliding rods 21. A connecting rod 23 that slides along the length direction is slidably connected between the outer walls of the two sliding rods 21. A slicing blade 24 is provided at the lower end of the connecting rod 23. A blade groove 25 is formed downwards below the slicing blade 24 at the upper end of the support frame 1 to cooperate with it. The outer wall of the support frame 1... A slot 26 communicating with the knife groove 25 is opened at the front end and the length of the slot 26 is greater than the length of the knife groove 25 and they are matched to form a T-shaped setting. A pressing component 27 is provided at the rear end of the outer wall of the connecting rod 23. The pressing component 27 includes a hollow shell 28, a number of sliding holes 29 opened at equal intervals at the bottom of the shell 28, a number of pressing rods 3 corresponding to the sliding holes 29 and slidably connected to them, a number of pressing blocks 31 respectively disposed at the lower end of the pressing rods 3, and a number of second return springs 32 respectively disposed between the upper end of the pressing rods 3 and the upper end of the inner wall of the shell 28.

[0030] Each pressing rod 3 has a downward-facing positioning hole 33 on its upper outer wall. Several positioning rods 34, corresponding one-to-one with the pressing rods 3 and extending into their respective positioning holes 33, are positioned downwards on the upper end of the inner wall of the housing 28. Each second return spring 32 is sleeved on the outer wall of its corresponding positioning rod 34. A drive motor 35 is mounted on one side of the upper end of the outer wall of the limiting rod 22. A drive disc 36 is mounted on the outer wall of the drive motor 35's power output shaft. A rocker arm 37 is rotatably connected between the eccentric part of the drive disc 36 and one end of the outer wall of the connecting rod 23. A rocker arm 37 is mounted on both the left and right sides of the front end of the support frame 1. Positioning scales 38, the outer walls of the two positioning scales 38 are slidably connected to an adjustment component 39 that slides along its length. The adjustment component 39 includes a T-shaped fixed rod 4, through holes 41 opened on the left and right sides of the front end of the outer wall of the fixed rod 4, threaded holes 42 opened on the left and right sides of the outer wall of the fixed rod 4 and communicating with the corresponding through holes 41, two fixing bolts 43 that are threadedly connected to the threaded holes 42, multiple pressure sensors 44 installed on the rear end of the outer wall of the fixed rod 4, and a baffle 45 that is configured to cooperate with the rear end of the pressure sensor 44. The rear end of the baffle 45 is configured to cooperate with the front end of the slot 26.

[0031] A rotatable screening component 46 is rotatably connected to the front end of the support frame 1 below the slot 26. The screening component 46 includes a U-shaped fixed frame 47, three screens 48 arranged along the height of the fixed frame 47 and inclined downward from front to back, and rocker arms 49 rotatably connected between the front and rear ends of the left and right sides of the outer wall of the fixed frame 47. The diameter of the screen holes of the screens 48 increases from bottom to top. At the rear end of the left and right sides of the inner wall of the fixed frame 47, a guide plate 5 is inclined downward and rearward at the lower end of each screen 48. The length of the guide plate 5 extending from the rear end of the fixed frame 47 increases from bottom to top. A wedge-shaped rod is vertically arranged on the other side of the outer wall of the connecting rod 23, with its lower rear end shaped like a wedge. The guide rod 54 is provided, and a wedge-shaped fixing block 52 is provided on one side of the outer wall of the fixed frame 47, which cooperates with the lower end of the guide rod 54. When the guide rod 54 slides down, it can push the screening component 46 to rotate backward. When the guide rod 54 slides up, the fixed frame 47 can be restricted by the fixing block 52 to return to the initial state left and right, so as to prevent the fixed frame 47 from rotating excessively. A roller 53 is rotatably connected to the front end of the outer wall of the fixing block 52. A conical guide hopper 51 is provided inside the support frame 1 between the screening component 46 and the knife groove 25. A control panel 56 is provided at the rear end of the outer wall of the support frame 1. The electric push rod 2, the drive motor 35 and the pressure sensor 44 are all electrically connected to the control panel 56 through connecting wires (figure not shown).

[0032] Usage: First, move the device to the appropriate position and fix the support frame 1. Then, power it on. Place the medicinal material to be sliced ​​on the conveyor roller 11 on the support frame 1. Then, use the pushing assembly 14 to fix the rear end of the root / stem medicinal material to be sliced. Next, pull the lever 18 upwards to allow the pressure plate 17 to slide upwards along the second slide groove 16. Then, place the rear end of the medicinal material into the slider 15. Release the lever 18. The return action of the first return spring 19 will allow the pressure plate 17 to contact the medicinal material and limit and fix it to a certain extent. Then, slide the adjusting assembly 39 on the positioning scale 38 to control the slice size. Loosen the threads in the threaded hole 42. The rod is used to slide the fixed rod 4 through the through hole 41 on the two positioning scales 38 to adjust the distance between the baffle 45 and the groove 26. After adjustment, the fixing bolt 43 is rotated to fix the adjusting component 39. Then, the control panel 56 is operated to make the electric push rod 2, the drive motor 35 and the adjusting component 39 work. The electric push rod 2 pushes the slider 15 to slide in the first groove 13 on the baffle 12 and pushes the medicine towards the knife groove 25. The partition 55 can prevent the debris on the raw medicine from falling into the screening component 46 and the ground. When the front end of the medicine contacts the rear end of the baffle 12, it will apply a force to the pressure sensor 44 to make it pressurized.

[0033] Then the drive motor 35 on the limit rod 22 starts working and drives the drive disk 36 to rotate. The drive disk 36 then drives the connecting rod 23 to slide up and down along the outer wall of the slide rod 21 via the rocker arm 37. When the connecting rod 23 slides down, the lower end of the pressing component 27 will first contact the outer wall of the medicine to fix the front end of the medicine. When the pressing block 31 contacts the medicine, as the connecting rod 23 continues to slide down, it will cause the pressing rod 3 to retract into the housing 28 and squeeze the second return spring 32. At this time, the length of the pressing rod 3 extending out of the housing 28 is determined by the size of the medicine. Meanwhile, the rebound force of the second return spring 32 will provide a certain degree of support and fixation for the medicinal material. As the connecting rod 23 continues to slide down, the slicing knife 24 slices the medicinal material and passes through the lower end of the knife groove 25. At this time, the rocker arm 37 on the drive disk 36 is at its lowest position, and the sliced ​​medicinal material will fall into the screening component 46 through the guide hopper 51 for screening. Then, the rotating disk drives the connecting rod 23 to slide upward, and then the electric push rod 2 extends again to push the medicinal material forward. By repeating this process, the continuous slicing of the medicinal material can be achieved.

[0034] During this process, the pressing rod 3 can achieve relatively stable up and down sliding under the cooperation of the positioning rod 34 and the positioning hole 33, avoiding the pressing rod 3 from tilting and affecting its normal operation. When the connecting rod 23 slides down, the guide rod 54 will contact the roller 53 at the front end of the fixed block 52 and push the screening component 46 backward. When the guide rod 54 moves away from the fixed block 52, the rocker arm 49 will drive the fixed frame 47 to swing forward. This reciprocating motion improves the screening effect on the sliced ​​medicinal materials. The medicinal slices that enter the fixed frame 47 first fall on the uppermost screen 48, and the shaking of the fixed frame 47 moves the sliced ​​medicinal materials towards the rear end. Smaller medicinal slices will fall down step by step to achieve multi-stage screening. The medicinal slices that have been screened and moved backward will slide backward through the guide plate 5. Since the guide plate 5 has different lengths at different heights, it can also prevent the medicinal materials from mixing and facilitate collection.

[0035] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make inventive modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
