Description

Technical Field

[0001] This utility model belongs to the field of Dendrobium officinale processing technology, and in particular, it is a Dendrobium officinale grinding device. Background Technology

[0002] The stems of Dendrobium officinale are used in medicine and belong to the category of yin-tonifying tonics. They have the effects of nourishing the stomach and promoting the production of body fluids, as well as nourishing yin and clearing heat. During the processing of Dendrobium officinale, grinding equipment is required. However, when existing grinding equipment grinds Dendrobium officinale, it is very easy to generate iron metal fragments during the grinding process. These iron metal fragments mix with Dendrobium officinale, reducing the grinding quality of Dendrobium officinale.

[0003] A search revealed a design for an ultrafine powder grinding device for Dendrobium officinale (publication number CN219356492U). This device includes a body with a support assembly at the lower end and a top plate connected to the upper end. A motor is mounted on the top plate, and a ring is fixedly connected to the outer side of the upper end of the body. Inside the body is a grinding assembly consisting of an upper grinding element, a middle grinding element, and a lower grinding element, arranged sequentially from top to bottom. The grinding assembly rotates by connecting to the motor output. Several grinding plates that cooperate with the grinding assembly are fixedly connected sequentially from top to bottom inside the body. This invention achieves more thorough grinding of Dendrobium officinale through multiple grinding passes. However, this device does not consider the potential for generating iron metal fragments during use, which could mix with the Dendrobium officinale, reducing the grinding quality. Utility Model Content

[0004] The purpose of this invention is to provide a Dendrobium officinale grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Dendrobium officinale grinding device, comprising:

[0006] The grinding box used for grinding Dendrobium officinale has two drive motors installed on the outer wall of the grinding box. The output shaft of the drive motors is connected to the grinding rollers through a coupling. Connecting plates are welded to both ends of the bottom of the grinding box. Mounting frames are welded to the bottom surfaces of the two connecting plates. A conveyor with a magnetic conveyor belt is installed on the inner bottom wall of the mounting frame.

[0007] The agitation assembly for turning and tumbling Dendrobium officinale includes a linear motor and a U-shaped fixed plate. The moving part of the linear motor is welded to a mounting plate. Several hollow telescopic outer rods are welded to the bottom surface of the mounting plate. A moving ring is slidably connected to the inner side wall of the telescopic outer rod. A telescopic inner rod for turning and tumbling Dendrobium officinale is welded to the inner surface of the moving ring.

[0008] Preferably, the bottom surface of the fixing plate is welded to the mounting bracket, and the inner top wall of the fixing plate is detachably connected to the fixing end of the linear motor by bolts.

[0009] Preferably, a plug rod is embedded in the top surface of the telescopic inner rod and a pressure-boosting spring is sleeved on the side of the plug rod.

[0010] Preferably, the two ends of the pressure spring are welded to the telescopic outer rod and the telescopic inner rod, respectively, and the top surface of the plug rod is welded to the telescopic outer rod.

[0011] Preferably, a collection box is embedded and fixedly connected to the bottom surface of the mounting frame, and limit bearings are embedded and fixedly connected to the two inner side walls of the collection box.

[0012] Preferably, the inner ring of the limiting bearing is interference-fitted with a rotating block, and a rotating rod is welded to the adjacent sides of the two rotating blocks.

[0013] Preferably, a scraper is welded to the side of the rotating rod, and the end face of the scraper abuts against the magnetic conveyor belt of the conveyor.

[0014] Preferably, one of the rotating blocks has a rotating motor connected to its end face via a coupling. The fixed end of the rotating motor is installed on the outer side wall of the collection box, and four support rods arranged in an array are welded to the bottom of the mounting frame.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This Dendrobium officinale grinding device uses two drive motors to power two grinding rollers that rotate in opposite directions, grinding the Dendrobium officinale. The ground Dendrobium officinale is then fed into the top of a magnetic conveyor belt through the discharge port. Because the grinding device itself is highly abrasive during the grinding process, iron metal fragments mix with the Dendrobium officinale. The magnetic conveyor belt adsorbs these iron metal fragments, preventing impurities from contaminating the Dendrobium officinale and improving the grinding quality. A tumbling component further agitates and tumbles the ground Dendrobium officinale, ensuring thorough contact between the remaining iron metal fragments and the magnetic conveyor belt, thus enhancing the removal of these fragments.

[0017] This Dendrobium officinale grinding device, under the elastic thrust provided by the pressure spring, causes the moving ring to move along the inner cavity of the telescopic outer rod, thereby bringing the bottom surface of the telescopic inner rod into contact with the magnetic conveyor belt of the conveyor. The pressure spring provides a buffering effect, preventing the telescopic inner rod from directly contacting the magnetic conveyor belt and causing damage to it. The plug-in rod provides a fixing effect on the moving path of the telescopic inner rod, while preventing the pressure spring from bending during extension and retraction, thus improving the structural stability of the device's components.

[0018] This Dendrobium officinale grinding device includes a collection box for collecting iron metal debris mixed inside the Dendrobium officinale. A scraper contacts the bottom surface of a magnetic conveyor belt, causing relative movement between the belt and the scraper. This scraper removes the iron metal debris magnetically adsorbed on the conveyor belt surface, enabling continuous cleaning of the iron metal debris mixed inside the Dendrobium officinale. Simultaneously, the scraper allows the iron metal debris to fall into the collection box for collection. A rotary motor provides power, and the angle of the scraper can be easily adjusted during transmission to ensure close contact between the scraper and the conveyor belt, improving the scraping effect. A limiting bearing fixes the rotational position of the rotating block, which in turn fixes the rotational position of the rotating rod, ensuring that the scraper and rotating rod rotate around a central axis.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] To address the issue that grinding devices for Dendrobium officinale easily mix iron-containing metal fragments with the inside of the Dendrobium officinale during use, thus reducing the grinding quality, please refer to [link to relevant documentation]. Figures 1 to 4 The structure of the device body includes:

[0030] The grinding box 1 is used for grinding Dendrobium officinale. Two drive motors 3 are installed on the outer wall of the grinding box 1. The fixed ends of the two drive motors 3 are detachably connected to the outer wall of the grinding box 1 by bolts. The output shaft of the drive motor 3 is connected to the grinding roller 2 through a coupling. During the rotation of the output shaft of the two drive motors 3, the two grinding rollers 2 are driven to rotate in opposite directions, so that the two grinding rollers 2 provide grinding processing for Dendrobium officinale during the rotation. The top and bottom surfaces of the grinding box 1 are respectively equipped with a feed inlet and a discharge outlet. Dendrobium officinale is introduced into the grinding box 1 through the feed inlet and the ground Dendrobium officinale is discharged through the discharge outlet.

[0031] The grinding box 1 has connecting plates 14 welded to both ends of its bottom. The two connecting plates 14 provide support and fixation for the grinding box 1. The bottom surface of the two connecting plates 14 is welded with a mounting frame 15. The bottom wall of the mounting frame 15 is equipped with a conveyor 13 with a magnetic conveyor belt. The conveyor 13 provides a conveying function for the ground Dendrobium officinale. During the grinding process of Dendrobium officinale, the internal structure of the grinding device generates iron metal fragments due to rotational friction. This causes the iron metal fragments to mix with Dendrobium officinale, reducing the grinding quality of Dendrobium officinale. The magnetic conveyor belt of the conveyor 13 provides a magnetic adsorption effect on the iron metal fragments, which facilitates the separation of Dendrobium officinale from the iron metal fragments, thereby improving the grinding quality of Dendrobium officinale.

[0032] The actuating assembly 4, used for turning and rotating the Dendrobium officinale, includes a linear motor 6 and a U-shaped fixing plate 5. The bottom surface of the fixing plate 5 is welded to the mounting bracket 15. The inner top wall of the fixing plate 5 is detachably connected to the fixed end of the linear motor 6 by bolts. The fixing plate 5 provides support and fixation for the linear motor 6. The moving part of the linear motor 6 is welded to a mounting plate 7. During the movement of the moving part of the linear motor 6, the mounting plate 7 moves laterally. Several hollow telescopic rods 8 are welded to the bottom surface of the mounting plate 7. A movable ring 9 is slidably connected to the inner wall of the 8. A telescopic inner rod 10 for turning and tumbling Dendrobium officinale is welded to the inner ring surface of the movable ring 9. The bottom surface of the telescopic inner rod 10 extends out of the inner cavity of the telescopic outer rod 8 and abuts against the magnetic conveyor belt of the conveyor 13. This allows the telescopic inner rods 10 to turn and tumble Dendrobium officinale during movement, so that the iron metal debris mixed inside Dendrobium officinale can fully contact the magnetic conveyor belt of the conveyor 13, thereby improving the cleaning effect of the iron metal debris mixed inside Dendrobium officinale and improving the grinding quality of Dendrobium officinale by the grinding device.

[0033] The top surface of the telescopic inner rod 10 is embedded with a sliding connection to a plug rod 11, which allows the telescopic inner rod 10 to move along the path of the plug rod 11, thereby enhancing the positional stability of the telescopic inner rod 10. A pressure spring 12 is sleeved on the side of the plug rod 11. The two ends of the pressure spring 12 are welded to the telescopic outer rod 8 and the telescopic inner rod 10, respectively. The pressure spring 12 provides elastic thrust, which helps to strengthen the contact force between the bottom surface of the telescopic inner rod 10 and the magnetic conveyor belt of the conveyor 13. At the same time, the pressure spring 12 provides a buffer protection function to prevent the telescopic inner rod 10 from being squeezed too much by the magnetic conveyor belt of the conveyor 13, which could damage the conveyor 13.

[0034] The plug-in rod 11 provides support for the pressure spring 12, preventing bending during the extension and retraction of the pressure spring 12 and improving the structural stability of the device components. The top surface of the plug-in rod 11 is welded to the telescopic outer rod 8. A collection box 16 is embedded and fixedly connected to the bottom surface of the mounting frame 15. The top of the collection box 16 is hollow, and the collection box 16 provides a collection function for ferrous metal debris. Limit bearings 17 are embedded and fixedly connected to the two inner side walls of the collection box 16. The inner ring of the limit bearing 17 is interference-fitted with a rotating block 18. The limit bearing 17 fixes the rotation position of the rotating block 18 and realizes the relative rotation of the rotating block 18 and the collection box 16. A rotating rod 19 is welded to the adjacent side of the two rotating blocks 18. Under the connection provided by the rotating blocks 18, the rotation position of the rotating rod 19 is fixed. A scraper 20 is welded to the side of the rotating rod 19.

[0035] The scraper 20 end face abuts against the magnetic conveyor belt of the conveyor 13. The scraper 20 scrapes away the iron metal debris magnetically adsorbed on the surface of the magnetic conveyor belt of the conveyor 13, realizing continuous cleaning of the iron metal debris mixed inside the Dendrobium officinale by the grinding device, and improving the grinding quality of Dendrobium officinale. One of the rotating blocks 18 end faces is connected to a rotary motor 21 through a coupling. The rotary motor 21 provides power, and the output shaft of the rotary motor 21 rotates to drive the rotating block 18 to rotate. During the transmission, the angle of the scraper 20 is adjusted so that the scraper 20 is in close contact with the magnetic conveyor belt of the conveyor 13, improving the cleaning effect of the iron metal debris magnetically adsorbed on the surface of the magnetic conveyor belt of the conveyor 13. The fixed end of the rotary motor 21 is installed on the outer wall of the collection box 16. The fixed end of the rotary motor 21 is detachably connected to the outer wall of the collection box 16 by bolts. Four support rods 22 arranged in an array are welded to the bottom of the mounting frame 15.

[0036] The drive motor 3, linear motor 6, conveyor 13, and rotary motor 21 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] Working principle

[0038] In use, the Dendrobium officinale grinding device introduces Dendrobium officinale into the grinding box 1 through the feed inlet. Two drive motors 3 are started, and their output shafts rotate, driving two grinding rollers 2 to grind the Dendrobium officinale. The ground Dendrobium officinale then falls through the discharge port onto the top surface of the magnetic conveyor belt of the conveyor 13. The magnetic conveyor belt magnetically attracts the iron metal fragments mixed inside the Dendrobium officinale. A linear motor 6 is then started, and its moving part moves. Under the connection provided by the mounting plate 7, several telescopic inner rods 10 agitate and tumble the Dendrobium officinale during transmission. Simultaneously, the moving rings 9 welded to the sides of the telescopic inner rods 10 move along the inner cavity of the telescopic outer rod 8, causing the telescopic inner rods 10 and the telescopic outer rod 8 to compress the pressure spring 12.

[0039] The iron metal debris is magnetically attracted to the magnetic conveyor belt of conveyor 13, causing the Dendrobium officinale to separate from the iron metal debris under the conveyor 13. The rotary motor 21 is started, and the output shaft of the rotary motor 21 rotates, driving the rotating block 18 to rotate. During the transmission process, the scraper 20 rotates along the axis of the rotating rod 19. The angle of the scraper 20 is adjusted so that the scraper 20 is in close contact with the bottom surface of the magnetic conveyor belt of conveyor 13, so that the scraper 20 scrapes off the iron metal debris that is magnetically attracted to the surface of the magnetic conveyor belt of conveyor 13, and the iron metal debris falls into the collection box 16 for collection.
