Description

Technical Field

[0001] This invention relates to the field of tobacco leaf pretreatment processes, and more particularly to an apparatus and method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers. Background Technology

[0002] In recent years, with the strong demand for cleaner and more automated tobacco leaves in the tobacco threshing and re-drying industry, users have placed higher demands on the efficient and rapid removal of tobacco debris. Currently, the basic direction of similar research both domestically and internationally focuses on how to quickly and efficiently remove the fibrous fibers from the de-fiber removal rollers. For these rollers, online de-fiber removal machines mostly employ dual-station machines, while offline machines can only be cleaned when the machine is stopped. Both have disadvantages such as large footprint and inconvenient maintenance. For foreign objects removed by air separation, further manual sorting is still required to meet the requirements of re-drying enterprises, resulting in low automation and a waste of significant manpower and resources.

[0003] Traditional hemp fiber removal machines consist of a row of rotating hemp fiber removal rollers. Hook-shaped nylon fasteners or bristles are wound around these rollers. When tobacco leaves come into contact with the rollers, the hook-shaped nylon fasteners or bristles pick up the hemp fibers. However, once the hemp fibers are caught on the nylon fasteners, they are difficult to remove. Once the rollers are full of hemp fibers, the machine must be stopped and the fibers removed manually. Generally, after a period of use, when the rollers are saturated with hemp fibers, if manual cleaning is not timely, the machine will become ineffective. Because the hemp fibers are firmly attached and difficult to remove completely, the overall hemp fiber removal efficiency of the machine gradually decreases. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an apparatus and method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers, which has a high degree of automation and frees up manpower.

[0005] This invention provides an online hemp fiber removal and automatic cleaning device for hemp fiber rollers, comprising: at least two sets of machines, each set of machines equipped with multiple hemp fiber removal units.

[0006] The hemp fiber removal unit includes a power unit and a roller. The power unit is fitted with a roller to drive the roller to rotate.

[0007] One end of the roller is provided with a track, and a tractor is mounted on the track to move the roller.

[0008] A cleaning unit, shaped like an arch, is located near the roller end of the track. During cleaning, the roller passes through the cleaning unit.

[0009] The cleaning unit includes any two or three of the following: blade brush, nail brush, and needle brush arranged side by side;

[0010] The hemp fiber removal control unit controls the hemp fiber removal units of different groups of machines to rotate alternately in a circular motion for removing hemp fibers.

[0011] Preferably, the tractor moves on the linear guide rail using gear and rack transmission.

[0012] Preferably, each machine group is equipped with 8 to 10 hemp fiber removal units.

[0013] Preferably, it includes two sets of machines, which are connected, arranged vertically, or arranged horizontally.

[0014] Preferably, from the roller end to the track end, the cleaning unit includes three sets of components arranged in sequence: a blade brush, a nail brush, and a needle brush.

[0015] Preferably, the cleaning unit further includes an air nozzle disposed at the top of the blade brush, nail brush, and needle brush.

[0016] Preferably, the tractor is equipped with a traction control unit.

[0017] This invention also provides a method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers, comprising the following steps:

[0018] The tobacco leaves enter the hemp fiber removal unit from above. The control unit controls the hemp fiber removal unit to rotate circumferentially. The rollers make full contact with the tobacco leaves, and the impurities and hemp fibers in the tobacco leaves are stuck to the rollers. The tobacco leaves are then collected from below.

[0019] After receiving the signal from the hemp fiber removal unit, a set of machines is activated by the tractor control unit, which controls the tractor to move the roller on the track. At this time, the hemp fiber removal unit is divided into two parts, becoming the roller and the power unit. After the roller passes through the cleaning unit, the blades in the cleaning unit can cut off the hemp fibers that are difficult to remove and are wrapped around the surface of the roller. Then, the roller surface is cleaned by brushes of different densities of nail brushes and needle brushes. After being blown by compressed air nozzles, the roller surface is cleaned.

[0020] While one set of machines performs linear motion to clean the intelligent hemp fiber removal unit, another set of machines performs circular rotation to adhere hemp fibers and debris in the tobacco leaves. The two sets of machines then alternately perform the hemp fiber removal and cleaning steps.

[0021] Compared with the prior art, the device and method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers of the present invention includes multiple sets of machines, with different sets of machines alternating to remove and clean hemp fibers. This ensures that while cleaning the hemp fibers and debris on the rollers, the hemp fiber removal unit also works to clean the hemp fibers and debris in the material, thereby achieving the process requirements of online removal of hemp fibers and automatic cleaning of the hemp fiber removal rollers, and freeing up manual labor.

[0035] The cleaning unit 6 also includes an air nozzle 8, which is disposed at the top of the blade brush, nail brush and needle brush.

[0036] The hemp fiber removal control unit 7 controls the hemp fiber removal units of different groups of machines to rotate alternately in a circular motion for removing hemp fibers.

[0037] This invention also provides a method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers, comprising the following steps:

[0038] The tobacco leaves enter the hemp fiber removal unit from above. The control unit controls the hemp fiber removal unit to rotate circumferentially. The rollers make full contact with the tobacco leaves, and the impurities and hemp fibers in the tobacco leaves are stuck to the rollers. The tobacco leaves are then collected from below.

[0039] After receiving the signal from the hemp fiber removal unit, a set of machines is activated by the tractor control unit, which controls the tractor to move the roller on the track. At this time, the hemp fiber removal unit is divided into two parts, becoming the roller and the power unit. After the roller passes through the cleaning unit, the blades in the cleaning unit can cut off the hemp fibers that are difficult to remove and are wrapped around the surface of the roller. Then, the roller surface is cleaned by brushes of different densities of nail brushes and needle brushes. After being blown by compressed air nozzles, the roller surface is cleaned.

[0040] While one set of machines performs linear motion to clean the intelligent hemp fiber removal unit, another set of machines performs circular rotation to adhere hemp fibers and debris in the tobacco leaves. The two sets of machines then alternately perform the hemp fiber removal and cleaning steps.

[0041] To further understand the present invention, the apparatus and method for online removal of hemp fibers and automatic cleaning of hemp fiber rollers provided by the present invention will be described in detail below with reference to embodiments. The scope of protection of the present invention is not limited by the following embodiments.

[0042] Example 1

[0043] According to process requirements, Machine No. 1 and Machine No. 2 can be connected; Machine No. 1 and Machine No. 2 have the same structure, each containing 10 sets of intelligent hemp fiber removal units and 3 sets of cleaning units.

[0044] Unit 1 and Unit 2 each have their own control unit for independent control.

[0045] The tobacco leaves enter the intelligent de-fiber unit from above and are evenly distributed throughout the working space of the de-fiber unit.

[0046] The intelligent hemp fiber removal unit rotates in a circular motion under the control of the hemp fiber removal control unit. At this time, the hemp fiber removal roller is in full contact with the tobacco leaves, and the impurities and hemp fibers in the tobacco leaves are stuck to the roller, and the tobacco leaves are collected from below.

[0047] After receiving the signal from the hemp fiber removal unit, Machine No. 1 activates the railcar control unit, which then controls the railcar 1 to move the traction roller unit along the straight track. At this point, the intelligent hemp fiber removal unit splits into two: a roller unit and a hemp fiber removal power unit.

[0048] After passing through the cleaning unit, the roller unit's blades cut off the stubborn hemp fibers wrapped around the roller surface. Then, a series of brushes with varying densities of nail brushes and needle brushes clean the roller surface. Finally, a compressed air nozzle blows through the surface, resulting in a thoroughly cleaned roller surface.

[0049] While machine No. 1 performs linear motion to clean the intelligent hemp fiber removal unit, machine No. 2's intelligent hemp fiber removal unit rotates in a circular motion to adhere hemp fibers and debris in the tobacco leaves, and vice versa. This ensures that while the hemp fiber rollers are cleaning the hemp fibers and debris on them, the hemp fiber rollers are also working to clean the hemp fibers and debris from the material, thus achieving the process requirements of online hemp fiber removal and automatic cleaning of the hemp fiber removal rollers, freeing up manual labor.
