Description

Technical Field

[0001] This utility model relates to the field of plant extraction technology, and in particular to a refining device for high-purity plant extracts. Background Technology

[0002] Plant extracts are substances extracted from plants through specific processes. The refining process involves several key steps: raw material selection and preparation, washing and drying, crushing, extraction, filtration and concentration, drying, sieving, and packaging. In the crushing process, plant raw materials need to enter the crusher through an inclined channel and inlet. Due to the need for precise control of the feed rate, the inlet is usually designed to be relatively narrow. However, when processing leafy materials such as tea leaves and mulberry leaves, these materials are prone to accumulating and clogging at the inlet during the feeding process. This clogging not only affects production efficiency but also often requires manual intervention to clear, increasing the labor intensity of operators and posing safety hazards. Especially in continuous production processes, inlet blockage can force the entire production line to stop, seriously affecting production efficiency and product quality. Most existing refining devices lack effective automatic anti-clogging designs and cannot automatically detect and clear material accumulation, which has become a key bottleneck restricting the improvement of efficiency in plant extract refining processes. To address these issues, existing technologies urgently need improvement. Utility Model Content

[0003] The main purpose of this invention is to propose a refining device for high-purity plant extracts, which aims to solve the problem of easy material blockage in the crushing process. It has the advantages of automatic detection and unblocking of material accumulation, improved production efficiency, and reduced manual intervention and safety risks.

[0004] To achieve the above objectives, the purification apparatus for high-purity plant extracts proposed in this utility model includes: Inclined passage; The feed inlet is located at the bottom end of the inclined channel; A pushing device is provided at the feed inlet. The pushing device includes an outward pushing device and an inward pushing device.

[0005] In one embodiment, the pushing device includes a driving member, and the pushing device includes a first pushing frame disposed above the feed inlet.

The protruding rod is disposed on the top of the wedge block. The drive component drives the drive frame to move toward the first push frame. The inclined surface of the wedge block pushes the top of the first push frame downward. After the first push frame inserts the accumulated material, the protruding rod contacts the sliding frame and pushes the sliding frame to move, so that the first push frame pushes the material outward.

[0007] In one embodiment, the drive frame further includes a connecting plate, and the number of wedges and protrusions is two, with the two wedges and two protrusions located at opposite ends of the connecting plate.

A rotating plate, which is disposed above the rotating shaft and is vertically arranged; A torsion spring, the torsion spring being connected to the rotating shaft and the inclined channel sidewall; When the driving component moves, the push plate contacts the rotating plate and causes the rotating shaft to rotate, causing the second push frame to rotate downwards to push the accumulated material inwards.

[0012] In one embodiment, the second pusher frame consists of a plurality of pusher blocks arranged in an array.

[0013] In one embodiment, a plurality of sensors are provided on one side of the first pusher frame. The sensors are used to sense the material accumulation height. When the material accumulation height reaches the position of the sensor, the pusher device is activated.

[0022] Please see Figures 1 to 3 This application discloses a refining apparatus 1000 for high-purity plant extracts, which includes an inclined channel 1, a feed inlet 2, and a pushing device. The feed inlet 2 is located at the bottom of the inclined channel 1. The pushing device is located at the feed inlet 2 and includes an outward pushing device 3 and an inward pushing device 4. The outward pushing device 3 is used to push the accumulated material outward from the feed inlet 2, and the inward pushing device 4 is used to push the accumulated material inward from the feed inlet 2.

[0023] The inclined channel 1 can be made of metal or plastic, and its inclination angle is preferably 30-60 degrees. The opening size of the feed inlet 2 can be adjusted according to the material characteristics; for leafy materials, it is usually set to 5-15 cm. The external pushing device 3 can be implemented using a robotic arm, push plate, or rake-like structure, while the internal pushing device 4 can be implemented using a rotating blade or push rod structure. The power source for the pushing device can be an electric motor, a pneumatic device, or a hydraulic system.

[0024] This technical solution primarily addresses the problem of blockage at the feed inlet 2 during the refining process of plant extracts. Specifically, in the crushing process, leafy materials tend to accumulate at the narrow feed inlet 2. By incorporating a bidirectional pushing device, the material flow can be automatically adjusted. The outward pushing device 3 prevents excessive material accumulation, while the inward pushing device 4 ensures that an appropriate amount of material enters the processing equipment. Compared to manual unblocking, this device enables continuous production and improves work efficiency. The synergistic effect of the bidirectional pushing effectively maintains the stability of the material flow, preventing equipment downtime due to material accumulation.

[0025] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the refining device 1000 for high-purity plant extracts includes a drive member 5 and an outward pushing device 3. The outward pushing device 3 includes a first pushing frame 31, which is disposed above the feed inlet 2. The drive member 5 is used to drive the first pushing frame 31 to move downward to insert into the accumulated material and to move away from the feed inlet 2 to push the material outward.

[0026] This technical solution utilizes a drive component 5 to propel the first pusher frame 31 in a combined vertical downward insertion and horizontal outward pushing motion, effectively solving the problem of easy accumulation and blockage of leafy materials at the narrow feed inlet 2. The downward insertion of the first pusher frame 31 penetrates the material accumulation layer, while the horizontal outward pushing action evenly disperses the material. Compared to manual unblocking, this device achieves automated operation, significantly improving production efficiency. Simultaneously, by replacing manual intervention with mechanical propulsion, the risk of material contamination is avoided, ensuring the purity of the extract. This device is particularly suitable for the large-scale continuous production of sheet-like materials such as tea leaves and mulberry leaves.

[0027] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the pushing device 3 further includes a fixed frame 32, a sliding frame 33, and a driving frame 34. The sliding frame 33 is disposed on the first pushing frame 31 and slidably disposed on the fixed frame 32. The sliding frame 33 slides in the inclined direction of the inclined channel 1, and the first pushing frame 31 is vertically slidably disposed on the sliding frame 33. The driving frame 34 is disposed on one side of the first pushing frame 31 and is connected to the driving member 5. The driving frame 34 includes a wedge block 341 and a protruding rod 342, with the protruding rod 342 disposed on the top of the wedge block 341. The driving member 5 drives the driving frame 34 to move towards the first pushing frame 31, and the inclined surface of the wedge block 341 pushes the top of the first pushing frame 34, causing it to move downward. After the first pushing frame 34 inserts the accumulated material, the protruding rod 342 contacts the sliding frame 33 and pushes the sliding frame 33 to move, so that the first pushing frame 31 pushes the material outward.

[0028] The fixed frame 32 provides a sliding track for the sliding frame 33, which can use a linear guide or roller structure to achieve the sliding function. The wedge block 341 of the drive frame 34 can have a 45-degree inclined surface design, and the protruding rod 342 can have a cylindrical structure. The first push frame 31 and the sliding frame 33 can slide vertically through a T-slot structure. The drive component 5 can use a linear drive device such as a cylinder, hydraulic cylinder, or electric push rod. As a preferred embodiment, the wedge block 341 and the protruding rod 342 can be made of wear-resistant alloy steel to improve service life. A linear bearing can be installed between the sliding frame 33 and the fixed frame 32 to reduce frictional resistance. The movement stroke of the drive frame 34 can be precisely controlled by a limit switch.

[0029] Specifically, this technical solution achieves the continuous execution of two actions—vertical insertion and horizontal pushing—of the first pushing frame 31 through the linkage design of the drive frame 34 and the sliding frame 33. Specifically, the wedge block 341 first pushes the first pushing frame 31 downward into the material accumulation layer, and then the protruding rod 342 pushes the sliding frame 33, causing the first pushing frame 31 to move horizontally. This step-by-step action design effectively solves the problem of jamming in traditional single-direction pushing devices. Furthermore, the guiding effect of the fixed frame 32 and the sliding frame 33 ensures that the movement trajectory of the first pushing frame 31 is precisely controllable. Therefore, this device can efficiently clear material accumulation at the feed inlet 2, avoiding the need for manual intervention. Compared with existing technologies, this solution has the advantages of reliable operation, compact structure, and easy maintenance.

[0030] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the drive frame 34 further includes a connecting plate 343, and the number of wedge blocks 341 and protruding rods 342 is two, with the two wedge blocks 341 and the two protruding rods 342 located at both ends of the connecting plate 343 respectively.

[0031] Specifically, the connecting plate 343 serves as the basic structure of the drive frame 34, used to fix and connect the two wedge blocks 341 and the two protruding rods 342. The connecting plate 343 can be made of sheet metal by stamping, with a thickness between 3-5 mm to ensure sufficient structural strength. The two wedge blocks 341 are symmetrically arranged at both ends of the connecting plate 343, with a preferred slope angle of 30-45 degrees to provide smooth thrust transmission. The protruding rods 342 are located on the top of the wedge blocks 341, with a diameter of 8-12 mm and a length slightly exceeding the edge of the wedge blocks 341 to ensure effective contact with the sliding frame 33. As a preferred embodiment, the connecting plate 343, wedge blocks 341, and protruding rods 342 can be manufactured using a one-piece casting process to improve structural integrity and durability. Furthermore, adjusting bolts can be provided at both ends of the connecting plate 343 for fine-tuning the distance between the two wedge blocks 341 to accommodate feed inlets 2 of different widths.

[0032] Therefore, this technical solution significantly improves the stability and reliability of the pushing device by setting up a double wedge block 341 and a double convex rod 342 structure. The symmetrically arranged wedge blocks 341 can balance the force applied to the first pushing frame 31, avoiding the skew problem caused by unilateral force. Simultaneously, the double convex rod 342 design ensures uniform force distribution on the sliding frame 33, making the material pushing process smoother. Compared with a single-sided drive structure, this solution effectively solves the problem of mechanism jamming caused by uneven force distribution, improving the continuity of device operation. Furthermore, the connecting plate 343 simplifies the structure of the drive frame 34, facilitating manufacturing and maintenance, and providing a basic platform for possible future functional expansion.

[0033] Furthermore, this application also proposes that the top of the first pusher frame 31 has a smooth transition.

[0034] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that a first return spring 35 is provided between the fixed frame 32 and the sliding frame 33, and a second return spring 36 is provided between the sliding frame 33 and the first push frame 31.

[0035] Specifically, the first return spring 35 is used to return the sliding frame 33 to its initial position after the sliding frame 33 completes the external pushing action, and the second return spring 36 is used to restore the first push frame 31 to its raised state after the first push frame 31 completes the downward pressing action. As a preferred embodiment, the first return spring 35 can be a compression spring, with its two ends fixed to the limiting boss of the fixed frame 32 and the spring seat of the sliding frame 33, respectively; the second return spring 36 can be a tension spring, connected between the hook of the sliding frame 33 and the lifting ring of the first push frame 31.

[0036] Therefore, the automatic reset function of the pushing device can be achieved through the synergistic action of the two reset springs. When the driving component 5 stops applying force, the first reset spring 35 drives the sliding frame 33 to retract along the inclined channel 1, while the second reset spring 36 pulls the first pushing frame 31 upward to detach it from the material layer. This design effectively solves the problem that traditional pushing devices require an additional power source for reset. The rake-shaped structure of the first pushing frame 31 can smoothly comb through the material during the reset process, preventing secondary accumulation caused by the spring rebounding material. Compared with manual unblocking, this automatic reset mechanism improves the efficiency of handling blockages at the feed inlet 2 by approximately 40%, without interrupting the production process.

[0037] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the first pusher 31 is a rake-shaped structure.

[0038] A rake-shaped structure refers to a frame structure with multiple parallel, toothed components, similar to an agricultural rake. In practice, the rake teeth can be made of metal or high-strength plastic, and the spacing between the teeth can be adjusted according to the material characteristics. The ends of the rake teeth can be designed with rounded corners or a tapered shape to reduce movement resistance. As a preferred embodiment, the rake teeth are installed at a 5-15 degree angle to the horizontal plane for easy insertion into the material layer. The width of the rake-shaped structure can be matched to the width of the feed inlet 2 to ensure complete coverage of the material accumulation area.

[0039] The rake-shaped structure design enables the first pusher 31 to more effectively disperse and push accumulated materials. Multiple rake teeth can simultaneously penetrate the material to different depths, creating a layered pushing effect and preventing the material from clumping together. Compared with a single pusher plate structure, the rake-shaped structure significantly improves material dispersion efficiency, and is particularly suitable for easily entangled materials such as leaves. The gaps between the rake teeth allow fine materials to pass through, reducing pushing resistance. Thus, this structure effectively solves the clogging problem caused by material accumulation at the feed inlet 2, achieving a continuous and stable feeding process.

[0040] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that a push plate 37 be provided at the bottom of the connecting plate 343, and an inner pushing device 4 be provided between the drive frame 34 and the first push frame 31. The inner pushing device 4 includes a rotating shaft 41, a second push frame 42, a rotating plate 43, and a torsion spring 44. The rotating shaft 41 is rotatably disposed on the side wall of the inclined channel 1 and located above the feed inlet 2. The second push frame 42 is fixed to the rotating shaft 41 and is horizontally disposed. The rotating plate 43 is disposed above the rotating shaft 41 and is vertically disposed. When the drive member 5 moves, the push plate 37 contacts the rotating plate 43 and causes the rotating shaft 41 to rotate, causing the second push frame 42 to rotate downwards to push the accumulated material inwards. The torsion spring 44 is connected to the rotating shaft 41 and the side wall of the inclined channel 1. Specifically, the push plate 37 can be made of stamped metal sheet with a thickness of 3-5mm, and is fixedly connected to the connecting plate 343 by bolts. The rotating shaft 41 can be a 304 stainless steel shaft with a diameter of 30-50mm, and both ends are fixed to the side wall of the inclined channel 1 by bearing seats. The second push frame 42 can be composed of multiple push blocks welded together, with a spacing of 50-80mm between the push blocks. The rotating plate 43 can be made of steel plate with a thickness of 8-10mm and a height of 100-150mm. As a preferred embodiment, a torsion spring can be provided between the rotating shaft 41 and the second push frame 42 to realize the automatic reset of the second push frame 42.

[0041] Therefore, this technical solution, by setting up an internal pushing device 4, when the driving component 5 moves the driving frame 34, the pushing plate 37 contacts the rotating plate 43 and drives the rotating shaft 41 to rotate, causing the second pushing frame 42 to rotate downwards, pushing the material accumulated inside the feed inlet 2 inwards. The horizontal arrangement of the second pushing frame 42 ensures that the pushing direction is consistent with the material flow direction, and the vertical arrangement of the rotating plate 43 facilitates effective contact with the pushing plate 37. This design solves the problem of material accumulation inside the feed inlet 2 causing blockage in the prior art, achieving bidirectional material pushing and improving feeding efficiency. Compared with technical solutions that rely solely on the external pushing device 3, this application, through the synergistic effect of the internal and external pushing devices 3, can more effectively prevent material accumulation and ensure continuous and stable feeding.

[0042] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the second pusher 42 is composed of multiple pusher blocks arranged in an array.

[0043] Specifically, the pushing blocks are made of rectangular metal sheets with a thickness of 3-5 mm and a width of 20-30 mm, and the spacing between adjacent pushing blocks is 10-15 mm. In a preferred embodiment, the pushing blocks are fixed to the rotating shaft 41 by welding, forming an equidistant comb-like structure. Furthermore, the front end of the pushing block is machined into a rounded transition to reduce frictional resistance with the material. Thus, when the second pushing frame 42 rotates, multiple pushing blocks can form a continuous segmented pushing surface, achieving layered propulsion of the accumulated material.

[0044] The working principle of this technical solution is as follows: by designing the second pusher frame 42 as an array structure composed of multiple independent pusher blocks, multiple independent pusher units can be formed during rotation. Each pusher block can individually pass through the gaps in the material accumulation layer, effectively reducing the overall pushing resistance. Furthermore, when encountering large material clumps, the gaps between the pusher blocks allow some material to pass through, avoiding secondary blockage. Specifically, compared to the integral pusher plate 37, this structure can achieve a more uniform material dispersion effect, especially when handling easily entangled materials such as leaves; the independent action of multiple pusher blocks can prevent material from clumping together. Therefore, this design significantly improves the working efficiency of the internal pushing device 4 while reducing the load on the drive component 5.

[0045] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that a plurality of sensors 6 be provided on one side of the first pusher 31, the sensors 6 being used to sense the material accumulation height, and the pusher device being activated when the material accumulation height reaches the position of the sensor 6.

[0046] Specifically, sensor 6 can be a photoelectric sensor, an ultrasonic sensor, or a pressure sensor. The photoelectric sensor determines the stacking height by detecting the degree to which the material blocks light; the ultrasonic sensor measures the distance to the material surface by emitting and receiving ultrasonic signals; and the pressure sensor determines the stacking state by detecting changes in pressure applied by the material to the sensor. In a preferred embodiment, the sensors 6 are arranged at intervals along the height direction of the first push frame 31, forming multi-level detection points, which can more accurately determine the degree of material stacking. The sensor signals are connected to the control unit via wires or wireless transmission, and the control unit controls the drive component 5 to operate according to a preset threshold.

[0047] Therefore, this technical solution, by installing sensor 6 on the first pusher frame 31, achieves automatic detection of material accumulation height and intelligent start / stop of the pusher device. When the material accumulation reaches a preset height, sensor 6 triggers the pusher device to operate, promptly clearing the blockage at the feed inlet 2 and avoiding tedious manual intervention. Compared with existing technologies, this solution solves the technical problem of easy accumulation and blockage of leafy materials, improving the continuity and automation of the refining process. Specifically, the arrangement of multiple sensors 6 accurately judges the material accumulation state and prevents malfunctions; the cooperation between sensors 6 and the control unit achieves precise control, ensuring both effective clearing and avoiding unnecessary energy consumption.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
