Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing machinery technology, and in particular to an anti-sticking vibrating sieving device for a gastrodia elata slicer. Background Technology

[0002] Gastrodia elata is a traditional Chinese medicinal herb with high medicinal value and large market demand. In the processing of Gastrodia elata, grading and sieving after slicing is a key step, requiring precise separation of slices of different thicknesses or sizes to meet the specifications for medicinal or processed medicinal products.

[0003] Currently, most common Gastrodia elata slice screening devices on the market use single-layer vibrating screens or simple multi-layer screen structures. However, in practical applications, the following problems exist: First, slice adhesion leads to low screening efficiency: Gastrodia elata slices are soft and contain mucus on their surface. Traditional screens are prone to adhesion during vibration due to friction between slices and mucus adhesion, forming "clumps" of material that cannot effectively pass through the screen holes, resulting in incomplete screening, reduced grading accuracy, and even requiring manual secondary sorting, increasing production costs. Second, the structure of multi-layer screening components is unreasonable: Although some multi-layer screening equipment achieves grading by stacking screens, the discharge ports of adjacent screen layers often adopt a coaxial straight-through design. Unscreened coarse material can easily pass directly through the upper screen and fall into the lower layer, causing mixing and affecting grading accuracy. At the same time, the screen fixing method is mostly rigid connection, which can easily lead to screen deformation or fatigue fracture due to long-term vibration, shortening the equipment life. Third, poor feed uniformity: Traditional equipment often uses a direct-fall feed design, causing the gastrodia slices to accumulate on the screen surface. This results in excessive local pressure, further exacerbating adhesion and making it difficult to achieve a uniform thin layer distribution, thus reducing screening efficiency. Fourth, difficulty in peeling off adhered materials: Traditional equipment lacks auxiliary peeling devices for materials already adhering to the screen or slice surface, requiring machine shutdown for cleaning or manual intervention, which affects continuous production efficiency.

[0004] Therefore, there is an urgent need for a vibrating sieving device for Gastrodia elata slicers that can solve the above problems, so as to improve sieving efficiency, grading accuracy and equipment stability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an anti-sticking vibrating sieving device for a gastrodia elata slicer.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an anti-adhesion vibrating sieving device for a Gastrodia elata slicer, comprising: a vibration support assembly for supporting and buffering vibration; a multi-layer sieving assembly axially stacked on the vibration support assembly, the multi-layer sieving assembly having an internal sieve mechanism for grading and sieving Gastrodia elata slices; a drive assembly installed at the bottom of the vibration support assembly for stimulating vibration; a feeding and anti-adhesion assembly installed at the top of the multi-layer sieving assembly for uniform feeding and preventing slices from sticking together; and an air blowing assembly disposed on the side wall of the discharge port of the multi-layer sieving assembly for assisting in peeling off materials adhering to the surface of the Gastrodia elata slices or sieve.

[0009] As a preferred embodiment of this utility model, the screen mechanism includes: an annular screen frame, which is a circular structure, with its outer periphery fully welded to the bottom inner wall of the screen frame; an elastic retaining ring, which is a C-shaped stainless steel spring sheet, the cross-sectional dimensions of which match the retaining groove of the annular screen frame, and is engaged in the retaining groove; a conical screen, which is an inverted conical structure, with its large-diameter end fitting against the inner side of the elastic retaining ring, and its small-diameter end extending to the center of the screen frame; and a flow guide belt, which is a spiral flexible belt, the spiral direction of which is consistent with the generatrix direction of the conical screen, the outer edge of the flow guide belt being stitched and fixed to the surface of the conical screen, and the inner edge being connected to the central axis of the screen frame.

[0010] As a preferred embodiment of this utility model, the driving assembly includes: a vibration bearing housing, consisting of two symmetrically arranged deep groove ball bearing housings, fixedly installed at the bottom of the vibration base; a vibration drive shaft, vertically rotatably mounted via the bearings in the vibration bearing housings; an eccentric fly disc, a disc-shaped metal part with a weight-reducing groove on its outer circumference, fixedly connected to one end of the vibration drive shaft via a flat key; a driven pulley, a synchronous belt pulley, fixedly connected to the other end of the vibration drive shaft via a flat key; a driving pulley, a synchronous belt pulley, fixedly installed on the output shaft of the vibration drive motor; a synchronous drive belt, a trapezoidal tooth synchronous belt, tensioned between the driving pulley and the driven pulley; and a vibration drive motor, fixedly installed at the bottom of the vibration base by bolts, with its output shaft coaxial with the driving pulley.

[0011] As a preferred embodiment of this utility model, the feeding and anti-adhesion assembly includes: a feeding inlet, located at the center of the top of the sieve cover, having a funnel-shaped structure; an inverted conical dispersing hopper, installed below the feeding inlet, with its large-diameter end connected to the feeding inlet and its small-diameter end extending to the top of the multi-layer sieving assembly; and a feeding assembly, symmetrically arranged on both sides of the inverted conical dispersing hopper, for uniformly pushing the Gastrodia elata slices onto the surface of the sieve mechanism. The feeding assembly includes: feeding bearing seats, consisting of two symmetrically arranged flange-type bearing seats, fixed to the top of the sieve cover by bolts; and a feeding bearing, which is self-aligning. A ball bearing is installed inside the material feeding bearing housing; the material feeding shaft is a stainless steel round shaft, with its two ends passing through the center holes of the two material feeding bearings and being interference-fitted with the bearings; the leveling mesh plate is an annular boss structure, and its outer circumference is detachably connected to the lower end of the material feeding shaft by bolts; a rotary drive motor is fixed to the top of the material feeding shaft by a motor bracket, and its output shaft is connected to the material feeding shaft by a flexible coupling; an elastic clamping pin has its lower end abutting against the upper surface of the leveling mesh plate, and its upper end passing through the radial through hole of the material feeding shaft and connected to a nut, used to adjust the rotational preload of the leveling mesh plate.

[0012] As a preferred embodiment of this utility model, the air blowing assembly includes: an air blowing pipe, which is a stainless steel rigid pipe (surface polished), vertically installed along the side wall of the discharge port of the multi-layer screening assembly, with its upper end connected to an external compressed air source; a nozzle, which is fan-shaped and installed at the end of the air blowing pipe, with the nozzle opening direction inclined towards the surface of the screen mechanism; and a compressed gas control valve, which is a pneumatic diaphragm regulating valve, located in the middle of the air blowing pipe, for adjusting the air blowing pressure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The staggered discharge structure of the multi-layer screening components avoids material mixing and improves grading accuracy: The side wall discharge ports of the bottom screen frame, middle screen frame and upper screen frame are arranged in a circumferential staggered manner. Unscreened coarse materials need to move along the screen vibration direction to the discharge port of the corresponding screen layer before they can fall into the next level. This completely avoids the cross-layer mixing problem caused by coaxial discharge in traditional equipment and ensures strict separation of material specifications at each level. 2. The elastic retaining ring and guide belt design of the screen mechanism enhances durability and optimizes material guidance: The elastic retaining ring (C-shaped stainless steel spring) is engaged in the groove of the annular screen frame, which can adapt to the slight deformation of the screen during vibration and reduce the risk of screen breakage caused by rigid stress; the outer edge of the spiral guide belt is sewn to the screen and the inner edge is connected to the central axis of the screen frame, which can guide the Gastrodia elata slices to move evenly downward along the spiral path, avoid accumulation, and improve screening efficiency; 3. The feeding and anti-adhesion components have a feeding structure that achieves uniform material distribution and reduces the initial adhesion rate: The inverted cone-shaped dispersing hopper disperses the concentrated falling material into a uniform thin layer. Combined with the symmetrically set adjustable pre-tightening force feeding components (the pressure of the flattening screen plate is adjusted by the elastic clamping pin), the Gastrodia elata slices can be gently and evenly pushed onto the screen surface, avoiding adhesion caused by local compression and reducing adhesion from the source. 4. The directional air blowing design of the air blowing component helps to peel off adhering materials and improve continuous production efficiency: The fan-shaped nozzles (tilted towards the screen surface) set along the side wall of the discharge port can accurately spray compressed air to peel off materials adhering to the slices or screen surface; the air blowing pressure can be adjusted by the pneumatic diaphragm regulating valve to adapt to different degrees of adhesion of Gastrodia elata slices (such as fresh slices and dried slices), ensuring a continuous and stable screening process without the need for frequent shutdowns for cleaning.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] In the attached diagram, all identical reference numerals refer to the same components.

[0017] Example 1: Basic type of Gastrodia elata slice anti-adhesion vibrating sieve device This embodiment is a basic sieving device suitable for conventional Gastrodia elata slices (1-3mm thick, medium mucilage content). The connection relationship and function of each component are as follows: Please see Figure 1 , Figure 2 Vibration support assembly 1: The vibrating seat 11 with a ring frame structure is positioned and fitted with the bottom of the multi-layer screening assembly 2 through the mounting groove opened on its upper part; the connecting cylinder 12 sleeved on the outer periphery of the multi-layer screening assembly 2 has its outer side wall elastically connected to the upper part of the vibrating seat 11 through the circumferentially evenly distributed shock-absorbing springs 13. The shock-absorbing springs 13 are cylindrical helical springs, which can buffer the vibration impact; the bolt mounting holes at the bottom of the vibrating seat 11 are used to fix the device to the working platform of the Gastrodia elata slicer to ensure the stability of operation.

[0018] Please see Figure 2 Multi-layer screening component 2: The bottom screen frame 21, middle screen frame 22, upper screen frame 23 and screen cover 24 are stacked from bottom to top and aligned by positioning pins. The screen mesh mechanism 3 is fixed in the mounting holes at the bottom of each screen frame. The discharge port 25 opened on the side wall of the bottom screen frame 21, the discharge port 25 opened at an offset on the side wall of the middle screen frame 22, and the discharge port 25 opened at an even more offset on the side wall of the upper screen frame 23 ensure that the unscreened material needs to move along the vibration direction to the corresponding level discharge port before falling, thus avoiding material mixing.

[0019] Screening mechanism 3: The annular screen frame 31 is a circular structure, with its outer periphery fully welded to the inner wall of the bottom of the screen frame to enhance rigidity; the C-shaped stainless steel elastic retaining ring 32 is engaged in the retaining groove of the annular screen frame 31, with its inner side fitting against the large diameter end of the inverted conical screen 33, and its small diameter end extending to the center of the screen frame; the outer edge of the spiral guide band 34 is sewn and fixed to the surface of the conical screen 33, and its inner edge is connected to the central axis of the screen frame. When vibrating, it guides the Gastrodia elata slices to move evenly downwards along the spiral path to prevent accumulation.

[0020] Drive assembly 4: The vibration bearing seat 41 fixed at the bottom of the vibration seat 11 vertically supports the vibration drive shaft 42 through the bearing; one end of the vibration drive shaft 42 is fixedly connected to the eccentric fly disk 43 with weight reduction groove through a flat key, and the other end is connected to the driven wheel 44 through a flat key; the driving wheel 47 on the output shaft of the vibration drive motor 46 is tensioned to the driven wheel 44 through the trapezoidal tooth synchronous drive belt 45. When the motor rotates, the eccentric fly disk 43 generates periodic excitation force, driving the multi-layer screening assembly 2 to vibrate.

[0021] Please see Figure 5 Feeding and anti-sticking components 5: The funnel-shaped feed inlet 51 at the top center of the screen cover 24 is connected to the inverted conical dispersing hopper 52 below, and the small diameter end of the dispersing hopper extends to the top of the multi-layer screening component 2; the feeding components 6 are symmetrically arranged on both sides of the dispersing hopper, and the feeding bearing seat 61 is fixed to the top of the screen cover 24. The self-aligning ball bearing 62 inside supports the stainless steel feeding shaft 63; the lower end of the feeding shaft 63 is detachably connected to the flattening screen plate 64 with an annular boss structure by bolts, and the top end is driven to rotate by the rotary drive motor 65 through the elastic coupling; the lower end of the elastic clamping pin 66 in the radial through hole of the feeding shaft 63 abuts against the upper surface of the flattening screen plate 64. By adjusting the screw depth of the pin, the pre-tightening force of the flattening screen plate 64 on the slices is controlled to achieve uniform material distribution.

[0022] Please see Figure 3 Air blowing assembly 7: The upper end of the stainless steel air blowing pipe 71, which is vertically installed along the side wall of the discharge port 25 of the multi-layer screening assembly 2, is connected to an external compressed air source, and the opening of the fan-shaped nozzle 72 at the end is inclined and points towards the surface of the screen mechanism 3; the compressed gas control valve 73 in the middle of the air blowing pipe 71 adjusts the air blowing pressure and peels off the material adhering to the surface of the slice or screen.

[0023] Example 2: Special screening device for high-viscosity Gastrodia elata slices This embodiment is optimized for fresh Gastrodia elata slices (high mucus content, easy to stick together), with a focus on adjusting the parameters of the feeding and anti-sticking components 5 and the air blowing component 7: In the feeding and anti-adhesion assembly 5, the flattening screen 64 adopts a denser annular boss structure (increasing surface area contact), the initial pre-tightening force of the elastic clamping pin 66 is reduced (reducing the squeezing of the slices), and in conjunction with the flexible rubber liner added to the inner wall of the inverted conical dispersion hopper 52 (reducing slice friction), the high viscosity slices are dispersed into a thinner flow layer, avoiding local accumulation and adhesion.

[0024] In the air blowing assembly 7, the initial opening of the compressed gas control valve 73 is increased (increasing the blowing pressure to 0.3-0.4MPa), and the tilt angle of the fan-shaped nozzle 72 is adjusted to 45° with the screen surface (enhancing the peeling force on vertically adhered sections), ensuring that high-viscosity sections are removed from the screen in time and avoiding clogging of the screen holes.

[0025] Example 3: Rapid-change screen type Gastrodia elata slice sieving device This embodiment focuses on the ease of maintenance of the screen mechanism 3, and is suitable for scenarios where screens of different mesh sizes need to be frequently replaced: In the screen mechanism 3, the groove depth of the annular screen frame 31 is increased to 5mm (to enhance the snapping stability of the elastic snap ring 32). The elastic snap ring 32, made of C-shaped stainless steel spring sheet, is equipped with pull rings at both ends (no new part number is added, utilizing the deformation design of the spring sheet itself). The old screen can be quickly removed by manually pulling the pull rings. The large diameter end of the conical screen 33 is bonded to the inner side of the elastic snap ring 32 (for auxiliary fixation), and the gap between the small diameter end and the central axis of the screen frame is filled with flexible sealant (to prevent material leakage from the slices). The guide belt 34 is fixed by stitching (the stitching is made of vibration-resistant nylon thread), and can be disassembled and cleaned simultaneously when replacing the screen, reducing downtime.

[0026] In the above embodiments, the components work together through modular design, which can not only meet the high-efficiency screening requirements of conventional Gastrodia elata slices, but also adapt to different material characteristics through parameter adjustment or structural optimization, reflecting the versatility and practicality of this utility model.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
