Technical Field
[0001] This application belongs to the field of traditional Chinese medicine processing, specifically relating to a surface cleaning device for Eucommia ulmoides. Background Technology
[0002] Eucommia bark, used as a traditional Chinese medicine, may contain natural or environmental debris on its surface after harvesting. This includes dust, soil, bark fragments, plant residues, and insects and their excrement. To ensure the quality and safety of the medicinal material, the Eucommia bark is cleaned before processing.
[0003] Most existing technologies involve cleaning with mechanically driven steel brushes. However, steel brushes are difficult to remove tightly adhered dirt, moss, or other organic residues, increasing the difficulty of subsequent water washing. Summary of the Invention
[0004] The technical problem to be solved by this application is to provide a surface cleaning device for Eucommia ulmoides, which can loosen the debris on the surface of Eucommia ulmoides bark and make it easier to clean.
[0005] This application provides a surface cleaning device for Eucommia ulmoides, comprising:
[0006] The conveyor includes a frame and a conveyor belt for conveying Eucommia bark;
[0007] The cleaning mechanism includes a drive assembly, a first pressure roller and a second pressure roller that span over the conveyor belt. The drive assembly is used to drive the first pressure roller and the second pressure roller to rotate synchronously. The surface of the first pressure roller is provided with a plurality of protrusions from one end to the other. The second pressure roller has a groove along its own length and forms a cutting edge at the transition between the groove and the surface.
[0008] Optionally, the shape of the protrusion structure includes at least one of the following: pyramidal, conical, frustum-shaped, and truncated cone.
[0009] Optionally, multiple protrusions are dispersed around the surface of the first pressure roller.
[0010] Optionally, the plurality of grooves are evenly distributed circumferentially, and the surface of the second pressure roller between two adjacent grooves is a rough surface.
[0011] Optionally, the drive assembly includes a mounting plate disposed on one side of the frame, a first motor disposed on the mounting plate, an active synchronous pulley rotatably disposed on the mounting plate and drivenly connected to the output shaft of the motor, a passive synchronous pulley rotatably disposed on the mounting plate, a synchronous belt for drivingly connecting the active synchronous pulley and the passive synchronous pulley, a tensioner disposed on the mounting plate, and the two ends of the first pressure roller and the second pressure roller. The active synchronous pulley is used to drive the second pressure roller to rotate, and the passive synchronous pulley is used to drive the first pressure roller to rotate.
[0012] Optionally, the cleaning mechanism further includes a plurality of unpowered rollers, with the first pressure roller and the second pressure roller disposed between the plurality of unpowered rollers.
[0013] Optionally, both ends of the unpowered roller are provided with elastic adjustment components. The elastic adjustment components include studs on the frame, multiple nuts screwed onto the studs, and springs sleeved on the studs and located between the multiple nuts. The inner shaft of the unpowered roller has through holes at both ends for sleeved onto the studs. The springs are located above the inner shaft of the unpowered roller and exert a downward elastic force on the inner shaft.
[0014] Optionally, the elastic adjustment assembly further includes a plurality of washers sleeved on the stud, wherein the plurality of washers respectively abut against both ends of the spring.
[0015] Optionally, the frame includes a base support, a crossbeam disposed on the top of the base support, a support frame disposed on the crossbeam, and a drive transmission assembly disposed on the support frame, the conveyor belt surrounds the support frame, and the drive transmission assembly is used to drive the conveyor belt.
[0016] Optionally, the bottom of the base bracket is provided with multiple universal wheels with brakes;
[0017] The drive transmission assembly includes a second motor and a plurality of pulleys mounted on the support frame, the pulleys transmitting the power generated by the second motor to the conveyor belt.
[0018] The beneficial effect of this application is that the drive assembly drives the first and second pressure rollers to rotate synchronously, transporting the Eucommia bark via a conveyor belt through the first and second pressure rollers in sequence. When the Eucommia bark passes the first pressure roller, these protrusions press into the debris adhering to the bark surface. The function of the protruding structure is to break the adhesion between the debris and the bark, loosening the soil, moss, or other organic residues that were originally tightly attached to the bark surface. Based on the loosening of debris by the first pressure roller, the second pressure roller scrapes the bark surface through its blade structure. The blade can effectively scrape and remove the loose debris from the Eucommia bark surface. After continuous processing by the two pressure rollers, most of the debris adhering to the surface of the Eucommia bark has been removed. The cleaned Eucommia bark continues to be conveyed out by the conveyor belt to enter subsequent processing stages (such as washing and drying), thereby improving the overall processing efficiency and cleanliness. Compared to traditional steel brush cleaning methods, this device can remove tightly attached debris more efficiently. The device adopts a graded treatment (loosening first and then scraping) to improve cleaning efficiency and reduce the difficulty of subsequent water washing. It is also simple in structure and easy to operate, making it suitable for automated processing of Chinese medicinal materials. It can effectively protect the bark of Eucommia ulmoides from damage and maintain the integrity of the medicinal materials. Attached Figure Description

Detailed Implementation
[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0025] like Figure 1-4 As shown, this application provides a Eucommia bark surface cleaning device, including: a conveyor 100 and a cleaning mechanism; wherein, the conveyor 100 includes a frame 110 and a conveyor belt 120 for conveying Eucommia bark; the cleaning mechanism includes a drive assembly 210, a first pressure roller 220 and a second pressure roller 230 spanning above the conveyor belt 120, the drive assembly 210 is used to drive the first pressure roller 220 and the second pressure roller 230 to rotate synchronously, the surface of the first pressure roller 220 is provided with a plurality of protrusions 221 from one end to the other end, and the second pressure roller 230 has a groove 231 along its own length direction and a blade 232 is formed at the transition between the groove 231 and the surface.
[0026] Compared with the prior art, the Eucommia ulmoides surface cleaning device provided in this application drives the first pressure roller 220 and the second pressure roller 230 to rotate synchronously via the drive assembly 210. Eucommia ulmoides bark is transported sequentially through the first pressure roller 220 and the second pressure roller 230 via the conveyor belt 120. When the Eucommia ulmoides bark passes through the first pressure roller 220, these protrusions press into the debris adhering to the bark surface. The function of the protrusion structure 221 is to break the adhesion between the debris and the bark, loosening the soil, moss, or other organic residues that were originally tightly attached to the bark surface. Based on the loosening of debris by the first pressure roller 220, the second pressure roller 230 scrapes the bark surface through its blade 232 structure. The blade 232 can effectively scrape and remove the loose debris from the Eucommia ulmoides bark surface. After continuous processing by two pressure rollers, most of the debris adhering to the surface of the Eucommia bark has been removed. The cleaned bark is then conveyed out by conveyor belt 120 to enter subsequent processing stages (such as washing and drying), thereby improving overall processing efficiency and cleanliness. Compared with traditional steel brush cleaning methods, this device can remove tightly adhered debris more efficiently. The device employs a tiered processing method (loosening first, then scraping) to improve cleaning efficiency, reduce the difficulty of subsequent washing, and features a simple structure and convenient operation. It is suitable for automated processing of Chinese medicinal materials, effectively protecting the Eucommia bark from damage and maintaining the integrity of the medicinal material.
[0027] In one possible implementation, the shape of the protrusion structure 221 includes at least one of the following: pyramidal, conical, frustum-shaped, and truncated cone. Specifically, multiple first pressure rollers 220 and second pressure rollers 230 can be provided, and they can be distributed alternately or in sections. The protrusion structures 221 on the surface of each first pressure roller 220 can all be pyramidal, conical, frustum-shaped, or truncated cone, or they can be randomly or orderly combined with the above-mentioned protrusion structures 221. The design of multiple shapes can improve the ability to destroy debris in different attachment states. Among them, the pointed structures of the pyramidal and conical shapes can penetrate into hard debris (such as dry mud clumps and moss) that are close to the surface of the bark, effectively piercing its attachment layer; the wider tops of the frustum-shaped and truncated cone shapes are suitable for pressing into larger, softer debris (such as plant residue and insect residue), loosening it by applying pressure over a large area.
[0028] In one possible implementation, multiple raised structures 221 are dispersedly arranged around the surface of the first pressure roller 220. Specifically, this dispersed arrangement ensures that all parts of the surface of the Eucommia bark are contacted by the raised structures as it passes through the first pressure roller 220. This allows for more uniform and comprehensive treatment of debris adhering to the bark, improving overall cleaning efficiency.
[0029] In one possible implementation, multiple grooves 231 are evenly distributed circumferentially, and the surface of the second pressure roller 230 between two adjacent grooves 231 is a rough surface (not shown in the figure). Specifically, the rough surface can be formed by scraping with a blade or by friction with sand and gravel. When the second pressure roller 230 applies scraping force to the surface of the Eucommia bark, loose debris is scraped up by the blade 232 or the rough surface and falls into the groove 231. The groove 231 can effectively collect and temporarily store the scraped debris, preventing it from re-adhering to the already cleaned medicinal material surface. The rough surface can increase the friction between the pressure roller and the bark surface, which helps to more thoroughly scrape off loose impurities. For some small particles that are not easily scraped off directly by the blade 232, the rough surface can further remove them through friction.
[0030] In one possible implementation, the drive assembly 210 includes a mounting plate 211 disposed on one side of the frame 110, a first motor 212 disposed on the mounting plate 211, an active synchronous pulley 213 rotatably disposed on the mounting plate 211 and drivenly connected to the output shaft of the motor, a passive synchronous pulley 214 rotatably disposed on the mounting plate 211, a synchronous belt 215 for driving the active synchronous pulley 213 and the passive synchronous pulley 214, a tensioner 216 disposed on the mounting plate 211, and the two ends of the first pressure roller 220 and the second pressure roller 230. The active synchronous pulley 213 is used to drive the second pressure roller 230 to rotate, and the passive synchronous pulley 214 is used to drive the first pressure roller 220 to rotate. Specifically, when the first motor 212 starts, its output shaft begins to rotate, driving the active synchronous pulley 213 to rotate directly or indirectly (such as through a coupling). The rotation of the active synchronous pulley 213 transmits power to the passive synchronous pulley 214 through the synchronous belt 215. The speed ratio between the active synchronous pulley 213 and the passive synchronous pulley 214 remains consistent through the transmission of the synchronous belt 215, ensuring that the first pressure roller 220 and the second pressure roller 230 can rotate synchronously. The tensioner 216 can adjust the tension of the synchronous belt 215 according to the actual situation to avoid a decrease in power transmission efficiency or slippage of the synchronous belt 215 due to loosening, thus ensuring the stable operation of the equipment for a long time.
[0031] In one possible implementation, the cleaning mechanism further includes multiple unpowered rollers 240, with a first pressure roller 220 and a second pressure roller 230 positioned between them. Specifically, each end of the inner shaft of the unpowered roller 240 is fitted with a bearing housing 260, which is mounted on the frame 110. The unpowered rollers 240 themselves are not actively driven; they only rotate slightly as the bark slides or rolls on their surface. These rollers act as support and guide components, assisting the bark in smoothly passing through the first pressure roller 220 and the second pressure roller 230, ensuring that the bark does not laterally shift or get stuck when passing the critical cleaning components (pressure rollers).
[0032] In one possible implementation, both ends of the unpowered roller 240 are provided with elastic adjustment components 250. Each elastic adjustment component 250 includes a stud 251 mounted on the frame 110, multiple nuts 252 screwed onto the stud 251, and a spring 253 sleeved on the stud 251 and located between the nuts 252. The inner shaft of the unpowered roller 240 has through holes at both ends for fitting the stud 251. The spring 253, located above the inner shaft of the unpowered roller 240, exerts a downward elastic force on the inner shaft. Specifically, the stud 251 is fixedly mounted on the frame 110, serving as the basic support structure for the entire elastic adjustment component 250. Multiple nuts 252 are screwed onto the stud 251. These nuts 252 are used to adjust the position of the spring 253 and control the pressure applied to the unpowered roller 240. The spring 253 is placed above the inner shaft, and the downward elastic force applied by the spring 253 ensures that the unpowered roller 240 can closely contact the surface of the Eucommia ulmoides bark. The degree of compression of the spring 253 is preset by adjusting the position of the nut 252 on the stud 251, thereby determining the basic pressure applied to the unpowered roller 240. When the bark of Eucommia ulmoides enters below the unpowered roller 240, if the bark is thick, it will push the roller upward. At this time, the spring 253 is further compressed, generating a greater reaction force to ensure that the roller always keeps in contact with the bark. If the bark is thin, the spring 253 will cause the roller to move downward, reducing the pressure on the bark and preventing damage to the medicinal material due to excessive squeezing.
[0033] In one possible implementation, the elastic adjustment assembly 250 further includes a plurality of washers 254 sleeved on the stud 251, with the washers 254 respectively abutting against both ends of the spring 253. Specifically, the washers 254 are sleeved on the stud 251 and located at the upper and lower ends of the spring 253, respectively, serving as a buffer and support interface between the spring 253 and the nut 252 or the frame 110, preventing lateral displacement or instability of the spring 253 during compression or extension.
[0034] In one possible implementation, the frame 110 includes a base support 111, a crossbeam 112 disposed on top of the base support 111, a support frame 113 disposed on the crossbeam 112, and a drive transmission assembly 130 disposed on the support frame 113. A conveyor belt 120 surrounds the support frame 113, and the drive transmission assembly 130 drives the conveyor belt 120. The conveyor 100, which includes the frame 110 and the drive transmission assembly 130, can be purchased commercially and will not be described in detail here.
[0035] In one possible implementation, the bottom of the base bracket 111 is provided with multiple casters 114 with brakes to facilitate the overall movement of the device.
[0036] The drive transmission assembly 130 includes a second motor 131 and multiple pulleys 132 mounted on the support frame 113. The pulleys 132 transmit the power generated by the second motor 131 to the conveyor belt 120. The multiple pulleys 132 (divided into active and passive types) operate as follows: When the second motor 131 is energized, its output shaft drives the active pulley to rotate. The active pulley transmits the rotational motion to the passive pulley via a transmission belt. The passive pulley is connected to the drive roller of the conveyor belt 120, thereby driving the drive roller to rotate. When the drive roller rotates, friction causes the conveyor belt 120 to move forward. Eucommia bark is placed on the conveyor belt 120 and conveyed forward with it to subsequent cleaning areas, such as the first pressure roller 220 and the second pressure roller 230.
