TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber processing, in particular to a flax fiber separating equipment. BACKGROUND

[0002] As a kind of natural plant fiber, flax fiber is widely used in textile and garment, home textile, industrial textile and other fields due to its high strength, moisture absorption, air permeability, antibacterial and biodegradable properties. In the processing flow of flax fiber, separating fiber is a crucial core process. Currently, flax fiber is generally separated by rotating parts with structures such as spikes and comb teeth, which are subjected to opening force and combing force generated by rotation to realize the separation of fiber bundles and the separation of impurities. Some equipment also has screening structure to screen the separated fibers and further improve the fiber quality. However, the distance between most separating mechanisms and screening mechanisms is fixed, which is not convenient for quick adjustment according to the initial state of the fibers to be processed, such as fiber bundle thickness, adhesion degree and target separating fineness, so that the separating strength may not be adapted to different processing requirements. For example, when the distance is too small, the fibers are easily broken by excessive pulling, resulting in loss of fiber length, and when the distance is too large, the thick fiber bundles cannot be fully opened, resulting in poor separating effect and affecting product quality. In view of this, we propose a flax fiber separating equipment. SUMMARY

[0008] Further, the screening mechanism comprises an arc-shaped fixed frame arranged below the ring-shaped cylinder, and a plurality of groups of screening rods fixedly connected to the inner wall of the arc-shaped fixed frame.

[0009] Further, the third driving mechanism comprises a third motor fixedly connected to one side of the shell, a connecting shaft fixedly connected to the output shaft of the third motor, and the connecting shaft penetrates through the shell and is rotationally connected to the inner wall of the shell.

It should be noted that the conveying belt one 201 and the conveying belt two 202 are annular conveying belts made of rubber material, the inner wall is closely attached to the surface of the conveying roller 2042, and power transmission is realized through friction;

[0021] The working principle of the present application is as follows: before the equipment is started, the distance between the screening mechanism 401 and the separation mechanism 301 is adjusted by the driving mechanism three 402 according to the initial state of the flax fiber to be treated, such as the thickness of the fiber bundle, the adhesion degree and the target separation fineness; The motor three 4021 is started, the output shaft of the motor three 4021 drives the connecting shaft 4022 to rotate horizontally, the connecting shaft 4022 transmits power to the commutator 4023, and the internal ninety-degree bevel gear is engaged to realize power conversion, and the horizontal rotating motion is converted into the vertical rotating motion of the threaded seat 4024; Since the threaded top rod 4025 is limited by the guide structure of the shell 101 and cannot rotate with the threaded seat 4024, the axial force generated by the threaded engagement drives the threaded top rod 4025 to ascend and descend in the vertical direction, thereby driving the arc-shaped fixed frame 4011 and the separation sieve rod 4012 fixedly connected thereto to ascend and descend synchronously, until the motor three 4021 is turned off after adjusting to the preset distance, and the separation parameter presetting is completed; When the equipment is formally operated, the two groups of motor one 2041 of the driving mechanism one 204 are started synchronously, the output shaft of the motor one 2041 drives the conveying roller 2042 to rotate, and the conveying belt one 201 and the conveying belt two 202 are driven to run synchronously through the friction between the conveying roller 2042 and the conveying belt; the flax material to be separated is evenly placed on the conveying belt one 201 and conveyed smoothly to the inside of the shell 101 by the conveying belt one 201, and finally accurately falls into the working gap between the separation mechanism 301 and the screening mechanism 401; Meanwhile, the driving mechanism two 302 of the fiber separation unit 300 is started, the motor two 3021 output shaft drives the fixed shaft 3022 to rotate at high speed, the fixed shaft 3022 drives the annular cylinder 3011 to rotate synchronously through the cross-shaped support 3012, the conical rods 3013 arranged in an annular array on the surface of the annular cylinder 3011 rotate at high speed with the annular cylinder 3011, when the flax material enters the working gap, the conical rods 3013 pierce into the adhered fiber bundle at the high-speed rotating tip, and the continuous opening force and carding force are generated in the rotating process, so that the originally bundled coarse fiber bundle is gradually separated into single fibers or fiber bundles meeting the fineness requirement, and the core fiber separation action is completed; The fiber mixture after fiber separation falls to the screening mechanism 401 under the action of gravity, the qualified fibers meeting the fineness requirement can smoothly pass through the screening gap between the screening rods 4012, fall on the inclined guide plate 403 below, and smoothly slide to the conveying surface of the conveying belt two 202 under the flow guiding action of the guide plate 403, while the coarse fiber bundles that are not completely separated and impurities are intercepted by the screening rods 4012 and remain on the screening mechanism 401, which can be removed by manual or subsequent cleaning mechanism after the equipment is stopped, so as to avoid the influence of impurity accumulation on the fiber separation effect; The qualified fibers falling on the conveying belt two 202 move to the direction of the conical discharge pipe 203 under the continuous conveying of the conveying belt two 202, and finally enter the pipe through the large-diameter end of the conical discharge pipe 203, and are discharged from the equipment through the small-diameter end, so as to connect the subsequent packaging, further carding and other processes; During the whole fiber separation and conveying process, the exhaust pipe 102 of the main unit 100 continuously plays a role, the dust, airflow and a small amount of short fibers generated during fiber separation are quickly discharged outside the shell 101 through the exhaust pipe 102, which on the one hand maintains the stable air pressure inside the equipment, avoids airflow disorder affecting fiber conveying and screening, and on the other hand reduces the accumulation of dust inside the equipment, protects the running accuracy of each moving part, and at the same time can improve the operating environment and reduce dust pollution.

[0022] In addition, the rotating speeds of the two groups of motors one 2041 can be independently adjusted through the frequency converter, so that the feeding speed of the conveying belt one 201 and the discharging speed of the conveying belt two 202 can be flexibly adjusted according to the matching requirements of the feeding amount and the fiber separation efficiency, so as to ensure that the residence time of the material in the fiber separation working gap meets the fiber separation requirements, effectively avoids the problems of material accumulation or discharging not in time, and guarantees the continuous and stable operation of the equipment.

[0023] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
