Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, and in particular to a screening device for processing Forsythia suspensa. Background Technology

[0002] In the processing of Forsythia suspensa, as a classic medicinal material for clearing heat and detoxifying and dispersing wind-heat, the screening process is not only a basic step to ensure the quality of the medicinal material, but also a key factor in determining the clinical efficacy, industry reputation and even the internationalization of traditional Chinese medicine. The screening process runs through the entire life cycle of Forsythia suspensa from the field to the medicine cabinet, and screening is a key step to ensure the quality of the medicinal material.

[0003] Traditional methods mainly rely on manual screening or simple mechanical vibrating screens. While manual screening can better control the separation accuracy of impurities, it suffers from low efficiency, high labor intensity, and poor screening consistency, making it difficult to meet the needs of large-scale production. On the other hand, although simple mechanical vibrating screens can increase the throughput, their fixed screen structure makes it difficult to adapt to the screening requirements of Forsythia suspensa with different particle sizes, and problems such as clogging and incomplete screening are prone to occur, resulting in a high impurity residue rate, which affects the purity of the medicinal material and the quality of subsequent processing. Therefore, a screening device for Forsythia suspensa processing is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a screening device for processing Forsythia suspensa, which has an adjustable screening frame structure and a combination of flexible vibration to avoid clogging and further improve the screening effect.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a screening device for processing Forsythia suspensa includes a screening box, a feeding hopper extending into the top of the screening box is fixedly connected to the top of the screening box, a horizontal support plate is fixedly connected to the inner side wall of the screening box, a rectangular frame is connected to the upper surface of the horizontal support plate through a flexible component, an adjustable screening frame is fixedly connected to the top of the rectangular frame, an elastic threaded sleeve in contact with the adjustable screening frame is fixedly connected to the bottom of the feeding hopper, and a plurality of elongated holes are formed on one side of the elastic threaded sleeve; a plurality of rollers are rotatably connected to the bottom of the rectangular frame, a cam and a wheel are rotatably connected to the upper surface of the horizontal support plate, the rollers are in contact with the cam and the wheel, and a driving mechanism is provided on the horizontal support plate for driving the cam and the wheel to rotate.

[0006] By adopting the above technical solution, Forsythia suspensa first enters the device through the feed hopper at the top of the screening box. An elastic threaded sleeve is installed at the bottom of the feed hopper where it contacts the adjustable screening frame. This elastic threaded sleeve serves two purposes: firstly, it cushions the impact of the falling Forsythia suspensa, reducing direct impact damage to the adjustable screening frame; secondly, multiple elongated holes on its side help the Forsythia suspensa to fall more evenly, preventing it from accumulating in one place. The adjustable screening frame is designed so that its mesh size can be adjusted according to actual needs. Different batches or sources of Forsythia suspensa may have different particle sizes. By adjusting the structure of the adjustable screening frame and changing the mesh size, the frame can adapt to the screening requirements of Forsythia suspensa with different particle sizes, avoiding clogging. After the Forsythia suspensa falls onto the adjustable screening frame... The drive mechanism is activated, causing the cam and roller to rotate. During rotation, the outer contours of the cam and roller continuously contact the roller, generating force that drives the roller to move, which in turn drives the rectangular frame. The rectangular frame is connected to the horizontal support plate via a flexible component. The flexible component acts as a buffer and adjuster during the movement of the rectangular frame, enabling the rectangular frame to drive the adjustable screening frame to achieve flexible vibration. This flexible vibration is not rigid or violent, but a relatively stable and gentle vibration. This device combines an adjustable screening frame structure with flexible vibration. Firstly, it can adjust the adjustable screening frame structure according to different particle sizes to avoid clogging. Secondly, the flexible vibration can effectively prevent clogging during screening, further making the screening more thorough.

[0007] A further configuration of the present invention is as follows: the adjustable screening frame includes a strip-shaped base plate, an adjusting rod is provided on the strip-shaped base plate, one end of the adjusting rod is rotatably connected to a sleeve, the other end of the adjusting rod is slidably connected to a rectangular tube, one end of the strip-shaped base plate is fixedly connected to a fixing rod, the sleeve is slidably connected to the fixing rod, a handle is threadedly connected to the outer side of the sleeve, and a movable rod is threadedly connected to the other side of the strip-shaped base plate, with the rectangular tube disposed on the movable rod.

[0008] By adopting the above technical solution, the sleeve can be loosened and its position adjusted by rotating the handle. At the same time, rotating the movable rod drives the rectangular tube to move, changing the size of the mesh formed by the intersection of the adjusting rod and the strip base plate. The mesh size of the adjustable screening frame can be adjusted conveniently and quickly to meet the screening needs of Forsythia suspensa with different particle sizes. The operation is simple, the flexibility is high, and the applicability of the screening device is enhanced.

[0009] A further embodiment of the present invention is that the flexible component includes an outer tube rotatably connected to a horizontal support plate, an inner shaft is inserted into the interior of the outer tube, and a spring is provided between the outer tube and the inner shaft, the spring being sleeved on the inner shaft.

[0010] By adopting the above technical solution, the outer tube of the flexible component is rotatably connected to the horizontal support plate, the inner shaft is inserted into the outer tube, and the spring is sleeved on the inner shaft and located between the outer tube and the inner shaft. When the drive mechanism drives the rectangular frame to vibrate, the inner shaft moves inside the outer tube, and the spring undergoes elastic deformation, which plays the role of buffering and flexible support, making the vibration more stable and gentle.

[0011] A further configuration of the present invention is as follows: the driving mechanism includes a motor fixedly connected to the upper surface of a horizontal support plate, and pulleys are fixedly connected to the output end of the motor, as well as the outer surfaces of the cam and the wheel, and V-belts are sleeved on two adjacent pulleys.

[0012] By adopting the above technical solution, when the motor is working, its output end drives the pulley to rotate, which in turn drives the pulleys on the cam and the wheel to rotate through the V-belt, causing the cam and the wheel to make circular motion. This, in turn, drives the rectangular frame to move through the rollers, causing the adjustable screening frame to vibrate. This provides a stable and reliable power source for the screening device, ensuring that the adjustable screening frame can vibrate continuously and regularly, thus achieving efficient screening operations.

[0013] A further feature of the present invention is that the strip-shaped base plate intersects with the adjusting rod to form a mesh, and the mesh diameter ranges from 1 to 2 cm.

[0014] By adopting the above technical solution, the mesh size is changed by adjusting the position of the adjusting rod, limiting the mesh diameter range to 1-2cm. This range is set according to the common particle size range of Forsythia suspensa, ensuring that Forsythia suspensa that meets the requirements can be effectively screened out. The particle size range of the adjustable screening frame is clearly defined, enabling the screening device to screen Forsythia suspensa in a targeted manner for a specific particle size range, improving the accuracy and efficiency of screening, and meeting the requirements of different production needs for the particle size of Forsythia suspensa.

[0015] A further provision of the present invention is that a first collection frame is provided at the bottom of the screening box, and a second collection frame is fixedly connected to the side wall of the screening box near the elongated hole.

[0016] By adopting the above technical solution, the second collection frame on the side wall of the screening box is used to collect the non-compliant Forsythia suspensa discharged from the higher end of the adjustable screening frame, and the first collection frame at the bottom is used to collect the compliant Forsythia suspensa that falls through the mesh, which facilitates the classification and collection of the screened Forsythia suspensa and makes it easier for subsequent processing and use.

[0017] A further configuration of the present invention is that the base circle radius of the cam is the same as the radius of the wheel, the position of the cam is far away from the second collection frame, and the position of the wheel is close to the second collection frame.

[0018] By adopting the above technical solution, the vibration amplitude of the rectangular frame is relatively small at the end closer to the second collection box and relatively large at the end farther from the second collection box during the vibration process. This is beneficial for the unqualified Forsythia suspensa to move from the higher end (far from the second collection box) to the lower end (closer to the second collection box) of the adjustable screening box and be discharged, thereby improving the movement and screening efficiency of Forsythia suspensa during the screening process.

[0019] A further feature of the present invention is that the angle between the adjustable filter box and the horizontal plane is adjustable in the range of 10-20°.

[0020] By adopting the above technical solution, during the screening process, under the action of vibration and its own gravity, Forsythia suspensa will move towards the lower end of the adjustable screening frame. At the same time, Forsythia suspensa with the required particle size will fall through the mesh, while those that do not meet the requirements will be discharged from one end of the adjustable screening frame. This inclined setting is conducive to the movement and screening of Forsythia suspensa on the adjustable screening frame, thus speeding up the screening process. It also makes it easier to collect the screened Forsythia suspensa separately, making the screening process smoother and more orderly.

[0021] The beneficial effects of this invention are: 1. The adjustable screening frame structure allows the screening device to flexibly adjust the mesh size of the adjustable screening frame according to the different particle sizes of Forsythia suspensa. This feature greatly enhances the applicability of the device. Whether facing various Forsythia suspensa raw materials with large differences in particle size, or according to the different requirements for Forsythia suspensa particle size at different production stages, it can achieve accurate screening by simply adjusting the adjustable screening frame structure, and avoid clogging of the mesh opening.

[0022] 2. Flexible vibration has significant advantages over rigid vibration. During the screening process, forsythia may accumulate and get stuck in the mesh of the adjustable screening frame due to its irregular shape and different particle size, causing blockage. The stable and gentle vibration force generated by flexible vibration can make forsythia roll and move continuously on the adjustable screening frame, reducing the friction and adhesion between forsythia and the mesh, thereby effectively avoiding blockage and ensuring the continuity and smoothness of the screening process.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Reference Figures 1-7A screening device for processing Forsythia suspensa includes a screening box 1. A feed hopper 2 extending into the top of the screening box 1 is fixedly connected to its top. A horizontal support plate 8 is fixedly connected to the inner wall of the screening box 1. A rectangular frame 6 is connected to the upper surface of the horizontal support plate 8 via a flexible component 9. An adjustable screening frame 4 is fixedly connected to the top of the rectangular frame 6. An elastic threaded sleeve 3, in contact with the adjustable screening frame 4, is fixedly connected to the bottom of the feed hopper 2. The elastic threaded sleeve 3 is made of rubber, which has good elasticity and flexibility. When in contact with the adjustable screening frame 4 and when the forsythia passes through, it can undergo a certain degree of elastic deformation, reducing damage to the forsythia and better cooperating with the adjustable screening frame to ensure the smooth progress of the screening process. There are multiple elongated holes 5 on one side of the elastic threaded sleeve 3; multiple rollers 7 are rotatably connected to the bottom of the rectangular frame 6; cam 10 and wheel 12 are rotatably connected to the upper surface of the horizontal support plate 8; the rollers 7 are in contact with the cam 10 and wheel 12; a drive mechanism 11 is provided on the horizontal support plate 8 to drive the cam 10 and wheel 12 to rotate.

[0028] Forsythia suspensa first enters the device through the feed hopper 2 at the top of the screening box 1. An elastic threaded sleeve 3 is located at the bottom of the feed hopper where it contacts the adjustable screening frame 4. The elastic threaded sleeve 3 serves two purposes: firstly, it cushions the impact of the falling forsythia, reducing direct impact damage to the adjustable screening frame 4; secondly, its multiple elongated holes on the side help the forsythia to fall more evenly, preventing it from accumulating in one place. The adjustable screening frame 4 is designed so that its mesh size can be adjusted according to actual needs. Different batches or sources of forsythia may have different particle sizes. By adjusting the structure of the adjustable screening frame 4 and changing the mesh size, it can adapt to the screening requirements of forsythia with different particle sizes, avoiding clogging. After the forsythia falls onto the adjustable screening frame 4, the drive mechanism 11 is activated. The mechanism 11 drives the cam 10 and the wheel 12 to rotate. During the rotation, the outer contours of the cam 10 and the wheel 12 continuously contact the roller 7 and generate force, pushing the roller 7 to move, which in turn drives the rectangular frame 6 to move. The rectangular frame 6 is connected to the horizontal support plate 8 through the flexible component 9. The flexible component 9 plays a role in buffering and adjusting during the movement of the rectangular frame 6, so that the rectangular frame 6 drives the adjustable screening frame 4 to achieve flexible vibration. This flexible vibration is not rigid or violent vibration, but a relatively stable and gentle vibration mode. This device adopts an adjustable screening frame structure combined with flexible vibration. First, it can adjust the adjustable screening frame structure according to the particle size to avoid clogging. At the same time, the flexible vibration can effectively avoid clogging during the screening process, further making the screening more thorough.

[0029] The adjustable screening frame 4 includes a strip base plate 404, on which an adjusting rod 405 is provided. One end of the adjusting rod 405 is rotatably connected to a sleeve 403, and the other end of the adjusting rod 405 is slidably connected to a rectangular tube 407. One end of the strip base plate 404 is fixedly connected to a fixing rod 402, and the sleeve 403 is slidably connected to the fixing rod 402. A handle 401 is threadedly connected to the outside of the sleeve 403, and a movable rod 406 is threadedly connected to the other side of the strip base plate 404. The rectangular tube 407 is set on the movable rod 406. By rotating the handle 401, the sleeve 403 can be loosened and its position adjusted. At the same time, rotating the movable rod 406 drives the rectangular tube 407 to move, changing the mesh size formed by the intersection of the adjusting rod 405 and the strip base plate 404. The mesh size of the adjustable screening frame 4 can be easily and quickly adjusted to meet the screening needs of Forsythia suspensa with different particle sizes. The operation is simple, the flexibility is high, and the applicability of the screening device is enhanced.

[0030] The flexible component 9 includes an outer tube 901 rotatably connected to a horizontal support plate 8. An inner shaft 903 is inserted into the inner tube 901. A spring 902 is disposed between the outer tube 901 and the inner shaft 903. The spring 902 is sleeved on the inner shaft 903. The outer tube 901 of the flexible component 9 is rotatably connected to the horizontal support plate 8. The inner shaft 903 is inserted into the outer tube 901. The spring 902 is sleeved on the inner shaft 903 and located between the outer tube 901 and the inner shaft 903. When the drive mechanism 11 drives the rectangular frame 6 to vibrate, the inner shaft 903 moves within the outer tube 901, and the spring 902 undergoes elastic deformation, playing a role in buffering and flexible support, making the vibration more stable and gentle.

[0031] The drive mechanism 11 includes a motor 1102 fixedly connected to the upper surface of the horizontal support plate 8. The output end of the motor 1102 and the outer surfaces of the cam 10 and the wheel 12 are all fixedly connected to pulleys 1101. A V-belt 1103 is sleeved on two adjacent pulleys 1101. When the motor 1102 is working, its output end drives the pulleys 1101 to rotate. The V-belt 1103 drives the pulleys 1101 on the cam 10 and the wheel 12 to rotate, causing the cam 10 and the wheel 12 to make circular motion. This, in turn, drives the rectangular frame 6 to move through the roller 7, causing the adjustable screening frame 4 to vibrate. This provides a stable and reliable power source for the screening device, ensuring that the adjustable screening frame 4 can vibrate continuously and regularly, thus achieving efficient screening operations.

[0032] The strip-shaped base plate 404 intersects with the adjusting rod 405 to form a mesh. The mesh aperture range is 1-2cm. The mesh size is changed by adjusting the position of the adjusting rod 405, limiting the mesh aperture range to 1-2cm. This range is set according to the common particle size range of Forsythia suspensa, ensuring that Forsythia suspensa that meets the requirements can be effectively screened. The adjustable screening frame has a clearly defined particle size range, enabling the screening device to screen Forsythia suspensa in a targeted manner for a specific particle size range, improving the accuracy and efficiency of screening, and meeting the requirements of different production needs for the particle size of Forsythia suspensa.

[0033] A first collection frame 13 is provided at the bottom of the screening box 1, and a second collection frame 14 is fixedly connected to the side wall of the screening box 1 near the elongated hole 5. The second collection frame 14 on the side wall of the screening box 1 is used to collect the forsythia that does not meet the requirements discharged from the higher end of the adjustable screening frame, and the first collection frame 13 at the bottom is used to collect the forsythia that meets the requirements falling through the mesh, which facilitates the classification and collection of the screened forsythia, and makes it convenient for subsequent processing and use.

[0034] The base circle radius of cam 10 is the same as the radius of wheel 12. Cam 10 is located far from the second collection frame 14, while wheel 12 is located close to the second collection frame 14. This results in the rectangular frame 6 vibrating with a relatively smaller vibration amplitude at the end closer to the second collection frame 14 and a relatively larger vibration amplitude at the end farther from the second collection frame 14. This facilitates the movement and screening efficiency of forsythia that does not meet the requirements from the higher end (far from the second collection frame 14) of the adjustable screening box 4 to the lower end (closer to the second collection frame 14), thereby improving the movement and screening efficiency of forsythia during the screening process.

[0035] The adjustable screening frame 4 has an angle adjustment range of 10-20° with the horizontal plane. During the screening process, under the action of vibration and its own gravity, the Forsythia suspensa will move towards the lower end along the surface of the adjustable screening frame 4. At the same time, Forsythia suspensa with the required particle size will fall through the mesh, while those that do not meet the requirements will be discharged from one end of the adjustable screening frame. This inclined setting is conducive to the movement and screening of Forsythia suspensa on the adjustable screening frame 4, which speeds up the screening process. It also makes it easier to collect the screened Forsythia suspensa separately, making the screening process smoother and more orderly.

[0036] The present invention has the following effects: 1. The adjustable screening frame 4 structure is adopted, which enables the screening device to flexibly adjust the mesh size of the adjustable screening frame 4 according to the different particle sizes of Forsythia suspensa. This feature greatly enhances the applicability of the device. Whether facing a variety of Forsythia suspensa raw materials with large differences in particle size, or according to the different requirements for Forsythia suspensa particle size at different production stages, on the one hand, it can achieve accurate screening by simply adjusting the adjustable screening frame structure, and on the other hand, it avoids clogging of the mesh opening.

[0037] 2. Flexible vibration has significant advantages over rigid vibration. During the screening process, forsythia may accumulate and get stuck in the mesh of the adjustable screening frame 4 due to its irregular shape and different particle size, causing blockage. The stable and gentle vibration force generated by flexible vibration can make forsythia roll and move continuously on the adjustable screening frame, reducing the friction and adhesion between forsythia and the mesh, thereby effectively avoiding blockage and ensuring the continuity and smoothness of the screening process.
