Description

Technical Field

[0001] This utility model relates to the field of tobacco processing machinery technology, and in particular to a hemp fiber roller for quick cleaning of hemp fibers. Specifically, it relates to a device for efficiently removing hemp ropes, hemp fibers and other impurities mixed in with tobacco leaves during the tobacco re-drying and tobacco processing process, and for quickly cleaning the removing parts. Background Technology

[0002] In tobacco production, during the harvesting, transportation, and initial processing of tobacco leaves, fibrous impurities such as hemp rope and hemp fibers inevitably become mixed in. If these impurities are not effectively removed, they will directly affect the quality of subsequent cigarette products and may even cause equipment blockages, affecting the stable operation of the production line. Currently, there are two main methods for processing hemp fibers in the domestic tobacco industry: The first method uses a hemp fiber removal roller with hemp fiber clips (such as hook-shaped nylon fasteners) on its surface. When the tobacco leaves pass through, the hemp fibers are stuck to the clips. However, the adhesion capacity of the clips is limited; once saturated, the removal effect drops sharply, requiring the machine to be stopped for replacement. Replacing all the clips on the entire system is not only time-consuming (usually several hours) but also requires manual operation, severely consuming effective production time and increasing labor intensity and production costs.

[0003] The second method uses wire brush rollers. As the tobacco leaves pass through, the hemp fibers become entangled in the gaps between the wires, and a negative pressure suction device is used to clean them after production. While this method achieves a certain degree of automation, the cleaning process often takes 30 minutes to an hour, which is still quite long. Furthermore, it may not completely clean tightly entangled hemp fibers, sometimes requiring manual assistance, thus affecting overall production efficiency.

[0004] In addition, some improvements have been attempted in the existing technology. For example, published document CN116408264A discloses an online hemp fiber removal and automatic cleaning device for hemp fiber rollers. This device uses two sets of machines operating alternately; while one set removes the hemp fibers, the other set uses a tractor to send the rollers into an arch-shaped cleaning unit, where cleaning is performed using blade brushes, nail brushes, needle brushes, and air nozzles. Although this solution achieves online cleaning, the system structure is relatively complex, involving the separation, traction, and passage of the rollers through specific cleaning units, resulting in a large footprint and potentially high maintenance costs. Another document, CN218650229U, describes an automatic roller cleaning device with multi-layered guide rails, where the hemp fiber removal device can move to the cleaning station for multi-directional cleaning. However, its multi-layered design may result in a large overall height of the device, and the cleaning device is located below the hemp fiber rollers, making its structural layout significantly different from this invention.

[0005] Therefore, there is an urgent need in this field for a hemp fiber processing device that has a simpler and more compact structure, can complete the cleaning of hemp fibers in a very short time, minimize downtime, and ensure efficient removal of hemp fibers. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hemp fiber removal and rapid cleaning device with a hemp fiber roller. Its core purpose is to solve the problems of long cleaning time and low efficiency of hemp fiber removal components in the existing technology. Through innovative hemp fiber roller structure design and cleaning mechanism, it can achieve high-speed and effective removal of hemp fibers and near-instantaneous high-speed cleaning, which significantly improves the automation level and continuous operation capability of tobacco production lines.

[0007] The above-mentioned utility model objective is achieved through the following technical solution: This utility model provides a hemp fiber removal and rapid cleaning device using a hemp fiber roller, comprising: a hemp fiber roller assembly, a conveyor belt system, and a hemp fiber collection unit; the hemp fiber roller assembly includes at least one hemp fiber roller with a regular polygonal cross-section, each outer surface of which is provided with a steel wire layer for adhering and wrapping hemp fibers and a hemp fiber rapid cleaning plate that can be lifted relative to the steel wire layer; the conveyor belt system is located below the hemp fiber roller assembly for receiving and conveying tobacco leaves or the cleaned hemp fibers; the hemp fiber collection unit is located at the discharge end of the conveyor belt system for collecting the hemp fibers.

[0008] According to one embodiment of the present invention, the hemp fiber roller is provided with a driving mechanism, which is connected to the hemp fiber quick cleaning plate and is used to drive the hemp fiber quick cleaning plate to lift relative to the steel wire layer at the cleaning station.

[0009] According to one embodiment of the present invention, the driving mechanism is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The present invention also provides one such mechanism.

[0010] According to one embodiment of the present invention, the hemp fiber quick cleaning plate is made of a metal plate or an engineering plastic plate, and its surface has a wear-resistant coating.

[0011] According to one embodiment of the present invention, the hemp fiber roller group includes multiple parallel hemp fiber rollers, and the gap between each hemp fiber roller allows tobacco leaves to pass through but effectively blocks the hemp fibers.

[0012] According to one embodiment of the present invention, the conveyor belt system includes a drive roller, a tension roller, and a conveyor belt. The conveyor belt is tensioned between the drive roller and the tension roller, and the conveyor belt can rotate forward or reverse under the command of the control unit.

[0013] According to one embodiment of the present invention, a control unit is also included. The control unit is electrically connected to the drive mechanism and the conveyor belt system, and is used to control the lifting action of the hemp fiber quick cleaning plate to be carried out in coordination with the reverse cleaning operation of the conveyor belt system.

[0014] According to one embodiment of the present invention, the hemp fiber collecting unit is a hemp fiber collecting bucket, the top of which is provided with a funnel that connects to the discharge end of the conveyor belt system.

[0015] According to one embodiment of the present invention, the regular polygon is a regular hexagon or a regular octagon.

[0016] According to one embodiment of the present invention, the steel wire layer is composed of densely arranged high-carbon steel wires.

[0017] In summary, compared with the prior art, the present invention has at least one of the following beneficial technical effects: Extremely fast cleaning speed: The hemp fibers are pushed directly out of the steel wire layer using a liftable cleaning plate. The cleaning action is completed instantly (usually only a few seconds). Compared with traditional negative pressure fiber suction (30-60 minutes) or replacing hemp fiber clips (several hours), the cleaning efficiency is increased by several orders of magnitude, greatly reducing equipment downtime.

[0018] Simple and reliable structure: The core innovation of this utility model lies in the structural improvement of the hemp fiber roller itself. It does not require a complex roller separation traction system or multi-layer moving architecture. The overall structure is more compact, the manufacturing cost is lower, the failure rate may be lower, and maintenance is simple.

[0019] High degree of automation: The cleaning process (cleaning plate lifting, conveyor belt reversal) can be automatically controlled by the control unit, realizing one-button operation, reducing reliance on manual labor, and conforming to the development trend of industrial automation.

[0020] Stable rejection effect: The polygonal roller design allows the hemp fiber roller to better tumble the tobacco leaves when rotating, increasing the contact opportunities between the hemp fiber and the steel wire layer; at the same time, timely cleaning ensures that the steel wire layer always has good adhesion ability, thereby ensuring a continuous and stable hemp fiber rejection rate.

[0021] Highly practical: This device can be directly integrated into existing tobacco leaf conveying lines, with low modification difficulty and easy promotion and application, which can effectively improve the production efficiency and product quality of tobacco enterprises.

[0022] The core technological advantage of this hemp fiber removal and rapid hemp fiber cleaning device lies in its integrated polygonal hemp fiber roller design, which deeply integrates efficient hemp fiber removal with near-instantaneous cleaning action. Its unique liftable rapid hemp fiber cleaning plate can push the tangled hemp fibers out of the steel wire layer through simple mechanical movement without stopping the machine, achieving a fundamental shift from "periodic shutdown cleaning" to "online rapid cleaning." This avoids the long production interruptions caused by replacing hemp fiber clips or negative pressure suction in existing technologies, reducing cleaning time from tens of minutes or even hours to seconds, greatly improving equipment utilization and production continuity.

[0023] This device abandons the complex alternating work units, multi-layer moving guides, or independent cleaning stations and mechanisms commonly found in existing technologies. Instead, it highly integrates the cleaning function into the hemp fiber roller itself. This design not only significantly simplifies the equipment structure and reduces manufacturing and maintenance costs, but also achieves automatic collection of hemp fibers through the simple action of conveyor belt reversal, forming a smooth closed loop of "push-drop-collection." This solves the inherent problems of low reliability and large space occupation of complex systems, demonstrating outstanding advantages in simplicity and practicality.

[0024] Ultimately, the device achieves a simultaneous maximization of rejection and cleaning efficiency. The combination of the regular polygonal roller and the steel wire layer ensures a stable and high capture rate for removing hemp fibers, while the built-in drive mechanism ensures thorough and fast cleaning. The synergistic operation of both allows the equipment to maintain optimal operating conditions at all times. This integrated solution fundamentally improves the automation level and production efficiency of tobacco processing, representing a significant advancement compared to traditional methods.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] Example 1: Reference Figures 1-4 This utility model discloses a rapid cleaning device for removing hemp fibers using hemp fiber rollers, comprising: a hemp fiber roller assembly 1, a conveyor belt system 2, and a hemp fiber collection unit 3; the hemp fiber roller assembly 1 includes at least one hemp fiber roller 11, the cross-section of which is a regular polygon, specifically a hexagon or an octagon. In this embodiment, a regular hexagon is preferred. The hemp fiber roller assembly 11 includes multiple parallel hemp fiber rollers 11, the gaps between each hemp fiber roller 11 allowing tobacco leaves to pass through while effectively blocking hemp fibers.

[0034] Each outer surface of the hemp fiber roller 11 is provided with a steel wire layer 12 for adhering and wrapping hemp fibers, and a hemp fiber quick-cleaning plate 13 that can be lifted relative to the steel wire layer 12. The steel wire layer 12 is composed of densely arranged high-carbon steel wires; the hemp fiber quick-cleaning plate 13 is made of metal plate or engineering plastic plate, and its surface has a wear-resistant coating. A drive mechanism 4 is provided inside the hemp fiber roller 11, which is connected to the hemp fiber quick-cleaning plate 13 and is used to drive the hemp fiber quick-cleaning plate 13 to be lifted relative to the steel wire layer 12 at the cleaning station. The drive mechanism 4 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0035] The hemp fiber roller assembly 1 is the core working component. Its innovation lies in the fact that the cross-section of the hemp fiber roller 11 is designed as a regular hexagon. Each outer surface is a working unit, consisting of a bottom layer and an upper layer: the bottom layer is a steel wire layer 12, which is made of tightly arranged high-carbon steel wires and is used to stick and wrap the hemp fibers when the tobacco leaves pass through; the upper layer is a hemp fiber quick cleaning plate 13, which is flush with or slightly lower than the surface of the steel wire layer 12 under normal working conditions, but can be lifted upward under drive during cleaning.

[0036] The hemp fiber roller 11 integrates a drive mechanism 4, which is connected to the hemp fiber quick-cleaning plate 13 on each side. When cleaning is required, the control unit issues a command, the drive mechanism 4 actuates, and pushes the hemp fiber quick-cleaning plate 13 upward, thereby effectively "pushing" the hemp fibers wrapped and embedded in the steel wire layer 12 out of the steel wire bundle.

[0037] The conveyor belt system 2 is located below the hemp fiber roller assembly 1 and is used to receive and transport tobacco leaves or cleaned hemp fibers; the hemp fiber collection unit 3 is located at the discharge end of the conveyor belt system 2 and is used to collect hemp fibers.

[0038] The conveyor belt system 2 includes a drive roller 21, a tension roller 22, and a conveyor belt 23. The conveyor belt 23 is tensioned between the drive roller 21 and the tension roller 22, and can rotate forward or backward under the command of the control unit. It also includes a control unit, which is electrically connected to the drive mechanism 4 and the conveyor belt system 2, and is used to control the lifting action of the hemp fiber quick-cleaning plate 13 in coordination with the reverse cleaning operation of the conveyor belt system 2. The hemp fiber collection unit 3 is a hemp fiber collection bucket, with a funnel at its top that connects to the discharge end of the conveyor belt system 2.

[0039] Multiple hemp fiber rollers 11 are arranged horizontally and parallel above a conveyor belt 23, forming a rejection zone. As tobacco leaves pass through this zone, the hemp fibers are rejected by the hemp fiber rollers 11, and the purified tobacco leaves fall from the gaps between the hemp fiber rollers 11 onto the conveyor belt 23 below, where they are transported to the next process.

[0040] The conveyor belt system 2 is designed to operate in both forward and reverse directions. During normal production, it runs in the forward direction, conveying tobacco leaves. When it is necessary to clean hemp fibers, under the coordination of the control unit, the aforementioned quick-cleaning plate 13 is first lifted, causing the hemp fibers to fall onto the surface of the conveyor belt 23. Then, the conveyor belt 23 briefly reverses direction, conveying the hemp fibers to the discharge port at its tail end. The hemp fiber collection unit 3 (usually a hemp fiber collection bucket) is located below the discharge port at the tail end of the conveyor belt 23 to receive and store the cleaned hemp fibers.

[0041] The overall layout of this utility model device is as follows: A circular conveyor belt 23 serves as a material conveying platform. Above the conveyor belt 23, several (e.g., twelve) hemp fiber rollers 11 are installed in parallel, driven by independent drive motors (not shown in the figure) to rotate in the same direction as the tobacco leaves. The axis of the hemp fiber rollers 11 is aligned with the width direction of the conveyor belt 23. Below the tail of the conveyor belt 23, a hemp fiber collection bucket is placed to collect the hemp fibers that have been removed.

[0042] The hemp fiber roller 11 is the key component of this device. Its roller body cross-section is preferably a regular hexagon. For example... Figure 2 As shown, for each planar working unit of the roller body, its foundation is a hemp fiber quick-cleaning plate 13, which can be made of aluminum alloy or high-strength engineering plastic. On top of the hemp fiber quick-cleaning plate 13, a dense layer 12 of steel wires is fixed. These steel wires are made of elastic, wear-resistant high-carbon steel, similar to brush bristles. Under normal operating conditions, such as... Figure 2 As shown, the hemp fiber quick cleaning plate 13 is in close contact with the base plate of the hemp fiber roller 11 with the attached steel wire layer 12. The steel wire layer 12 is exposed and is responsible for winding the hemp fiber.

[0043] The hemp fiber roller 11 is hollow inside and houses the drive mechanism 4. In this embodiment, the drive mechanism 4 can be a series of small hydraulic cylinders, with the piston rod of each cylinder connected to the corresponding hemp fiber quick-cleaning plate 13 via a linkage mechanism. Of course, a pneumatic or electric linear drive scheme can also be used.

[0044] The device's workflow includes two main modes: rejection mode and cleanup mode.

[0045] Removal Mode: Tobacco leaves fall from the upstream equipment, passing through the area of ​​the hemp fiber roller 11. The rotating hemp fiber roller 11 effectively wraps around and removes the hemp fibers from the tobacco leaves using its steel wire layer 12. The cleaned tobacco leaves fall from the gap of the hemp fiber roller 11 onto the forward-moving conveyor belt 23 and are sent to the next processing stage. During this period, hemp fibers gradually accumulate in the steel wire layer 12 of the hemp fiber roller 11.

[0046] Cleaning mode: When the preset cleaning interval (such as time interval or tobacco leaf quantity threshold) is reached, the control unit (such as PLC) automatically starts the cleaning program.

[0047] Hemp fiber ejection: The control unit sends a signal to the drive mechanism 4 inside the hemp fiber roller 11. The drive mechanism 4 actuates, driving the hemp fiber quick-cleaning plates 13 on each working surface to rise upwards (e.g., Figure 3 (As shown in the diagram). This lifting action effectively pushes out the hemp fibers wrapped in the wire layer 12, detaching them from the wire. The hemp fiber roller 11 rotates slowly once during this process, ensuring that all surface hemp fibers are processed. The hemp fiber quick-cleaning plate 13 rises, pushing the hemp fibers in the middle of the wire layer 12 out from the top of the wire layer 12 (as shown in the diagram). Figure 4 (The state shown).

[0048] Collection of hemp fibers: The pushed-out hemp fibers fall onto the conveyor belt 23 below. Subsequently, the control unit controls the drive motor of the conveyor belt 23 to reverse, running for a predetermined period of time (e.g., 20-30 seconds). The reverse movement of the conveyor belt 23 transports the hemp fibers that have fallen on it to the tail end, and they fall into the hemp fiber collection bucket through the outlet funnel.

[0049] Reset: After cleaning is completed, the drive mechanism 4 drives the hemp fiber quick cleaning plate 13 to descend and reset, the conveyor belt 23 resumes forward operation, and the device continues to enter the rejection mode.

[0050] The entire cleaning process is extremely rapid, taking only about a minute from start to reset. The core hemp fiber ejection action is completed in just a few seconds, achieving near-instantaneous cleaning with minimal impact on the continuity of the production process. For those skilled in the art, parameters such as the number, diameter, and length of the hemp fiber rollers 11, and the width and speed of the conveyor belt 23 can be adaptively adjusted according to the actual production line's spatial layout and output requirements. The control logic can also be further optimized, for example, by linking it with the production line's central control system. These adjustments and modifications based on the core concept of this utility model all fall within the protection scope of this utility model.

[0051] The implementation principle of this utility model is as follows: This utility model discloses a rapid cleaning device for removing hemp fibers using hemp fiber rollers, belonging to the field of tobacco machinery technology. The device mainly includes a hemp fiber roller assembly 1, a conveyor belt system 2, and a hemp fiber collection unit 3. The hemp fiber roller 11 adopts a regular polygonal shape design, with a steel wire layer 12 and a liftable rapid cleaning plate 13 on each surface. Multiple hemp fiber rollers 11 are horizontally arranged above the conveyor belt 23. At the removal station, the hemp fiber roller 11 rotates, effectively wrapping and removing hemp fibers from the tobacco leaves using the steel wire layer 12. At the cleaning station, the cleaning plate is lifted by an internal drive mechanism 4, pushing the accumulated hemp fibers out of the steel wire layer 12 and onto the lower conveyor belt 23. The conveyor belt 23 then reverses to collect and transport the hemp fibers to a collection bin. This utility model achieves efficient and automated connection between hemp fiber removal and cleaning, solving the problems of time-consuming hemp fiber replacement and long cleaning cycles of steel wire brush rollers in existing technologies. It has significant advantages such as compact structure, fast cleaning speed, and high production efficiency.

[0052] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
