Description

Technical Field

[0001] The invention relates to the field of plant fiber extraction, in particular to a flax fiber separation device. Background Art

[0002] Currently, extracting flax fiber from flax plants requires first retting and degumming the flax plants, then vertically drying the retting flax plants until the moisture content is no more than 12%, then squeezing and crushing the flax stems, and then using a fiber separation device to remove wood debris from the flax fibers. Current fiber separation equipment usually uses high-speed rotating blades or large plates to strike the crushed flax stems to remove wood debris from the flax fibers. However, single flax fibers are only 15-25mm in length and have high rigidity and brittleness. The high-speed rotating blades will exert a large radial force on the wood debris, which is easy to tear the flax fibers when separated from the flax fibers, turning long fibers into short fibers and reducing the quality of the flax fibers. However, reducing the rotation speed cannot completely remove the wood debris from the flax fibers. Summary of the Invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1, with reference to Figure 1-Figure 5, which is the first embodiment of the present invention, provides a flax fiber fiber separation device, which includes an equipment housing 1 for fixing and supporting the housing of the entire equipment, a feed port 2 provided on the equipment housing 1 for feeding flax stalks into the equipment for crushing, a discharge port 3 provided on the equipment housing 1 for discharging flax fibers and wood chips, a fan 31 provided on the opposite side of the discharge port 3 for outputting airflow to drive the flax fibers and wood chips to be discharged from the discharge port 3, a pretreatment unit 4 provided on the equipment housing 1 for pre-treating the flax stalks for fiber separation, and a fiber separation unit 5 provided on the equipment housing 1 for performing a fiber separation operation on the flax stalks pretreated by the pretreatment unit 4; The pretreatment unit 4 includes a squeezing roller 41 provided on the device housing 1 for directly acting on the flax stalks for pretreatment, a driving assembly 42 provided on the device housing 1 for driving the squeezing roller 41 for rotating the squeezing roller 41, and a transmission assembly 43 provided on the device housing 1 for adjusting the movement of the squeezing roller 41 for adjusting the movement of the roller body 411 to achieve a better pretreatment effect. The fiber splitting unit 5 includes an electric push rod 51 provided on the device housing 1 for providing power, an extrusion assembly 52 provided on the driving end of the electric push rod 51 for cooperating with the drive of the electric push rod 51 to move along a specific trajectory, and a fiber splitting assembly 53 provided on the device housing 1 for receiving flax stalks pretreated by the pretreatment unit 4 and cooperating with the extrusion assembly 52 to perform a fiber splitting operation on the flax stalks. The driving assembly 42 and the transmission assembly 43 drive the squeezing roller 41 to squeeze and crush the flax rhizomes and tear them horizontally, so that the flax fibers and wood debris are initially separated. Then, the squeezing assembly 52 and the fiber separation assembly 53 further rub and separate the flax stalks that have been initially separated, thereby protecting the flax fibers and fully separating the wood debris on the flax.

[0031] In summary, first, the flax stalks after retting are put into the equipment housing 1 through the feed port 2 and contact the squeezing roller 41, so that the flax stalks in contact with the squeezing roller 41 maintain radial consistency with the squeezing roller 41. At this time, the driving component 42 and the transmission component 43 are started, driving the squeezing roller 41 to pre-treat the flax stalks in contact. At this time, the flax stalks pre-treated by the squeezing roller 41 fall into the fiber separation component 53. When a certain amount of flax stalks accumulate on the fiber separation component 53, the driving component 42 and the transmission component 43 stop. At this time, the electric push rod 1 51 is started, driving the squeezing component 52 to press the flax stalks on the fiber separation component 53. At this time, the fiber separation component 53 is started and cooperates with the pressure of the squeezing component 52 to perform fiber separation operation on the flax stalks. When the fiber separation is completed, the electric push rod 1 51 drives the squeezing component 52 to return to the initial position. At this time, the fan 31 is started, and the output airflow discharges the flax fibers and wood debris separated from the fiber separation component 53 out of the device through the discharge port 3. At this time, the fiber separation operation can continue.

[0032] Example 2, reference Figures 1-8 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: a specific structure of the pretreatment unit 4 in the flax fiber fiber separation equipment is provided. Compared with Example 1, further, the squeezing roller 41 includes a roller body 411 arranged on the equipment housing 1, and two groups of roller bodies 411 are arranged on the equipment housing 1. The roller body 411 has a wavy roller shaft. Through such an arrangement, when the flax stalk is placed on the roller body 411 in a direction consistent with the radial direction of the roller body 411, the two groups of roller bodies 411 rotate with each other, which can simultaneously squeeze the flax stalk in the radial and lateral directions, so that the flax fiber and the surface of the wood material are separated, and the wood material is squeezed and crushed at the same time. The connecting shaft 412 arranged on the roller body 411 is used to enhance the grip of the roller body 411 on the flax stalk and improve the pretreatment effect, and the grooves 413 arranged at both ends of the roller body 411, one group of grooves 413 is rotatably arranged on the equipment housing 1, and the other group of grooves 413 is slidably arranged on the equipment housing 1, playing a connecting role; The device housing 1 is provided with a sliding groove 11 that matches the groove 413 and is used to match the groove 413 to drive the relative positions of the two groups of rollers 411 to change.

[0033] The gap between the two groups of rollers 411 is located directly below the feed port 2 and is used to fully receive the flax stalks fed into it.

[0034] Among them, the driving component 42 includes a driving wheel 421 arranged on the device housing 1, which is used for rotation; a motor 422 arranged on the driving wheel 421, which is used to provide power to drive the driving wheel 421 to rotate; a transmission belt 423 arranged on the driving wheel 421, which is used to cooperate with the rotation of the driving wheel 421 to transmit power; and an output wheel 424 arranged on the transmission belt 423. The output wheel 424 is fixedly connected to the groove 413 connected to the device housing 1 for rotation, and is used to cooperate with the transmission of the transmission belt 423 to drive a group of rollers 411 to rotate.

[0035] The transmission assembly 43 includes a first gear 431 respectively provided on one group of grooves 413 for rotating in coordination with the rotation of the output wheel 424; a second gear 432 provided on another group of grooves 413 for connecting the first gear 431 and the second gear 432; a second transmission belt 433 provided on the first gear 431 and the second gear 432 for rotating in coordination with the rotation of the first gear 431, thereby driving the other group of rollers 411 to rotate; a vibration member 434 provided on the groove 413 for changing the relative distance between the second gear 432 and the first gear 431, thereby driving the distance between the two groups of rollers 411 to change; and a support wheel 435 provided on the second transmission belt 433 for fixing and supporting the first gear 431 so as to keep the first gear 431 in meshing with the second transmission belt 433. The gear ratio of gear 1 431 and gear 2 432 is different from one. This arrangement enables the two sets of rollers 411 to rotate differentially and respectively contact the inner and outer sides of transmission belt 2 433. This arrangement causes the two sets of rollers 411 to rotate in opposite directions. Combined with the differential rotation, this has a transverse tearing effect on the flax stalks in contact, thereby promoting the separation of flax fibers and wood chips.

[0036] The vibrating member 434 includes an adjusting wheel 4341 provided on the second transmission belt 433 for moving up and down to adjust the shape of the second transmission belt 433, thereby driving the two groups of rollers 411 to move relative to each other; a sliding block 4342 provided on the adjusting wheel 4341 for sliding limit; an abutting block 4343 provided on the adjusting wheel 4341 for connecting; an electric push rod 4344 provided on the device housing 1 for driving the abutting block 4343 for providing power to drive the adjusting wheel 4341 to move up and down; a connecting block 4345 provided on the two groups of grooves 413 for connecting; a telescopic rod 4346 provided between the connecting blocks 4345 for guiding; and a tensioning spring 4347 fixedly connected at both ends to the two groups of connecting blocks 4345 for providing a reaction force to maintain tension in the process of changing the shape of the second transmission belt 433, thereby ensuring accurate transmission between the parts. The device housing 1 is provided with a lifting slot 12 that cooperates with the sliding block 4342 and is used to cooperate with the sliding block 4342 to limit the up and down sliding of the adjusting wheel 4341.

[0037] The rest of the structure is the same as that of Example 1.

[0038] In summary, when the flax stalks enter the roller body 411 through the feed port 2, the motor 1 422 is started, and the output wheel 424 is driven to rotate through the driving wheel 1 421 and the transmission belt 1 423, thereby driving one group of roller bodies 411 to rotate. At this time, the output wheel 424 drives the gear 1 431 to rotate through the groove 413. Under the action of the gear 2 432 and the transmission belt 2 433, the other group of roller bodies 411 rotates synchronously. Due to the meshing relationship between the transmission belt 2 433 and the gear 1 431 and the gear 2 432, the two groups of roller bodies 411 rotate in opposite directions. At the same time, since the gear ratio of the gear 1 431 and the gear 2 432 is not unity, the two groups of roller bodies 411 rotate at a differential speed, which has the effect of horizontally tearing the flax stalks in contact. In order to expose more flax fibers, the flax stalks in contact are rolled between the rollers 411 for pre-processing. At this time, the electric push rod 4344 is started, driving the adjusting wheel 4341 to move up and down. At this time, the transmission belt 433 is pulled and its shape changes, driving one group of rollers 411 to slide relative to the other group of rollers 411 on the equipment housing 1. At this time, the tensioning spring 4347 is compressed and released in conjunction with the relative sliding between the rollers 411, maintaining the tension of the transmission belt 433, so that the transmission belt 433 maintains the transmission effect on each part. At this time, one group of rollers 411 moves back and forth relative to the other group of rollers 411, continuously vibrating the grabbed flax stalks at a low frequency, thereby promoting the separation of wood chips and flax fibers.

[0039] Example 3, reference Figures 1-11 This is the second embodiment of the present invention, differing from the previous embodiment in that it provides the specific structure of the fiber separation unit 5 in the flax fiber separation device. Compared to Example 2, the extrusion assembly 52 further includes a connecting plate 521 disposed on the driving end of the electric push rod 1 51, which is configured to move up and down in response to the drive of the electric push rod 1 51; a movable plate 522 slidably disposed on the connecting plate 521, which is configured to move in conjunction with the connecting plate 521; and guide shafts 523 disposed on either side of the movable plate 522, which serve as position limiters. At least two sets of guide shafts 523 are provided on each side to maintain the stable posture of the movable plate 522.

[0040] Among them, the equipment housing 1 is provided with a guide groove 13 and a guide groove 2 14 that cooperate with the guide shaft 523. The guide groove 13 is set to an inclined state, and the inclined direction is away from one side of the roller body 411. The guide groove 2 14 is set to a vertical state. The bottom of the guide groove 13 is connected with the top of the guide groove 2 14. Through such a setting, when the electric push rod 1 51 drives the connecting plate 521 to move downward, the movable plate 522 that is in sliding contact with the connecting plate 521 at this time slides downward while approaching the middle position of the fiber splitting assembly 53 through the cooperation of the guide shaft 523 and the guide groove 1 13. When the guide shaft 523 enters the guide groove 2 14 through the guide groove 1 13, the movable plate 522 is directly above the fiber splitting assembly 53. At this time, continuing to move downward through the guide groove 2 14 can squeeze the flax stalks on the fiber splitting assembly 53, and cooperate with the fiber splitting assembly 53 to perform fiber splitting operations.

[0041] Among them, the fiber splitting component 53 includes a fiber splitting platform 531 arranged on the equipment housing 1, which is used to receive the flax stalks pre-treated by the roller body 411, a motor 2 532 arranged on the equipment housing 1, which is used to provide power, a driving wheel 2 533 arranged on the driving end of the motor 2 532, which is used to rotate in conjunction with the motor 2 532, a transmission belt 3 534 arranged on the driving wheel 2 533, which is used to transmit in conjunction with the rotation of the driving wheel 2 533, and a fiber splitting part 535 arranged on the fiber splitting platform 531 and driven by the transmission belt 3 534, which is used to rotate in conjunction with the transmission of the transmission belt 3 534, and to perform fiber splitting operations on the flax stalks on the fiber splitting platform 531 in conjunction with the extrusion of the movable plate 522.

[0042] Among them, the fiber splitting component 535 includes a follower shaft 5351 rotatably set on the fiber splitting platform 531, which is used to cooperate with the transmission belt 3 534 for rotation; a sun gear 5352 set on the follower shaft 5351, which is used to cooperate with the follower shaft 5351 to rotate and rotate the planetary gear 5353 set on the fiber splitting platform 531 and meshingly connected with the sun gear 5352, which is used to rotate through the meshing transmission of the sun gear 5352, so that the rotation directions of the sun gear 5352 and the planetary gear 5353 are opposite; a fiber splitting plate 5354 set on the sun gear 5352 and the planetary gear 5353 is used to cooperate with the rotation, and through relative rotation, cooperate with the pressure of the movable plate 522 to form a low-speed three-dimensional rubbing flow field for the flax stalks, so that through repeated rubbing, the surface of the flax fiber and the wood debris produce shear fatigue and separate from each other; and a protrusion 5355 set on the fiber splitting plate 5354 is used to improve the gripping effect of the flax fiber.

[0043] The rest of the structure is the same as that of Example 2.

[0044] In summary, when the flax fibers fall onto the fiber separation platform 531 through the roller 411 and accumulate to a certain amount, the motor 1 422 and the electric push rod 2 4344 stop running. At this time, the electric push rod 1 51 drives the movable plate 522 to output downward through the connecting plate 521. At this time, the movable plate 522 slides along the trajectory of the guide groove 1 13 and the guide groove 2 14 through the guide shaft 523 to achieve the squeezing of the flax stalks on the fiber separation platform 531. At this time, the motor 2 532 is started and drives the follower shaft 5351 to rotate through the driving wheel 2 533 and the transmission belt 3 534. With the meshing action of the sun gear 5352 and the planetary gear 5353, the corresponding planetary gear 5353 forms a low-speed three-dimensional rubbing flow field, repeatedly rubbing the flax stalks between the movable plate 522 and the fiber separation platform 531, causing shear fatigue on the contact surface between the flax fibers and the wood chips, thereby separating from each other and completing the fiber separation operation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
