Description

Technical Field

[0001] This invention relates to the field of flax stalk crushing, and in particular to a flax stalk crushing device. Background Technology

[0002] To ensure full extraction of flax fiber, the flax stalks need to be crushed after retting to separate the woody and fiber layers, facilitating subsequent flax processing. Current stalk crushing equipment typically uses one or more pairs of counter-rotating rollers to forcefully compress the stalks passing through them, crushing the brittle woody layer while keeping the tougher fiber layer connected, thus achieving initial separation of the woody and fiber layers. However, this method of crushing the stalks instantly using rigid bosses results in peak stress concentration during crushing, which can easily cause radial splitting or transverse shearing of the flax fibers at the pressure point. Furthermore, due to the varying thickness of the flax stalks, coarse flax stalks are prone to over-compression during the crushing process, leading to flattened fiber layers, cell wall rupture, and a decrease in the mechanical strength of the flax fibers. Conversely, fine flax stalks are not crushed sufficiently, resulting in incomplete separation of the woody and fiber layers. Summary of the Invention

[0003] In view of the problems in the above-mentioned or existing technologies, when crushing flax stalks, the peak stress concentration can easily cause radial splitting or transverse shearing of flax fibers at the pressure point. At the same time, due to the different thicknesses of flax stalks, coarse flax is prone to over-compression during the crushing process, which flattens the fiber layer and ruptures the cell walls, resulting in a decrease in the mechanical strength of flax fibers.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, referring to Figure 1 and Figure 2This is the first embodiment of the present invention. This embodiment provides a flax stalk crushing device, which includes a device shell 1, which serves as the main body of the device and provides support and protection; a pretreatment unit 2 disposed on the device shell 1, which is used to grab flax stalks on the conveyor and pre-crush the flax stalks; a conveying unit 3 disposed on the device shell 1 to cooperate with the pretreatment unit 2, which is used to convey the flax stalks that have been pre-treated by the pretreatment unit 2; and a deep processing unit 4 disposed on the device shell 1 to cooperate with the conveying unit 3, which is used to further process the flax stalks conveyed by the conveying unit 3, so that the fiber layer and the wood layer are fully separated, which facilitates the subsequent flax threshing operation. The deep processing unit 4 includes a fixing plate 41 disposed on the equipment housing 1 for supporting the flax stalks conveyed by the conveying unit 3; a kneading component 42 disposed on the equipment housing 1 for cooperating with the fixing plate 41 for squeezing and kneading the supported flax stalks to separate the fiber layer and the wood layer; and a driving component 43 disposed on the equipment housing 1 for driving the kneading component 42 to move and cooperate with the fixing plate 41 to complete the squeezing and kneading actions. The flax stalks after retting are initially crushed by the pre-treatment unit 2, and then the initially crushed flax stalks are received by the conveying unit 3 and carried into the fixed plate 41. The driving component 43 drives the kneading component 42 to move, and the fixed plate 41 kneads the flax stalks thoroughly.

[0030] In summary, when the conveyor releases the bundled flax stalks and transports them towards the outer casing 1 of the equipment, the pretreatment unit 2 starts to grab the transported flax stalks and pre-process and crush them, causing the woody layer of the flax stalks to crack radially relative to the flax fibers. At this time, the conveying unit 3 starts to receive the flax stalks pre-processed by the pretreatment unit 2 and transport them onto the fixed plate 41. At this time, the drive component 43 starts to move the fixed plate 41 closer to the fixed plate 41, and works with the fixed plate 41 to squeeze the flax stalks, causing the flax stalks to crack laterally relative to the flax fibers. Then, the drive component 43 drives the kneading component 42 to move back and forth laterally relative to the flax stalks, working with the fixed plate 41 to knead the flax stalks. Through the mutual friction between the flax stalks, the fiber layer and the woody layer are fully separated.

[0031] Example 2, refer to Figures 1-5This is the second embodiment of the present invention. Unlike the previous embodiment, it provides the specific structure of the pretreatment unit 2 and the conveying unit 3 in the flax stalk crushing device. Compared to Embodiment 1, the pretreatment unit 2 further includes a gripping roller 21 mounted on the equipment housing 1 for rotation, with corner nails on the gripping roller 21 to increase the gripping force on the flax stalks and grip the flax stalks delivered by the conveyor; a first compression roller 22 mounted on the equipment housing 1 for rotation to initiate the conveying function; a second compression roller 23 mounted on the equipment housing 1 and located above the first compression roller 22 for matching the first compression roller 22 to crush the passing flax stalks; a first drive assembly 24 mounted on the equipment housing 1 for driving the gripping roller 21 and the first compression roller 22 to rotate; and an adjustment assembly 25 mounted on the equipment housing 1 for driving the second compression roller 23 to move up and down to adapt to the thickness of the flax stalk binding layer and prevent excessive compression or insufficient pressure on the flax stalks.

[0032] The drive assembly 24 includes a motor 241 mounted on the equipment housing 1 for providing power, a drive gear 242 mounted on the drive end of the motor 241 for rotating in coordination with the drive of the motor 241, a drive gear 243 mounted on the extrusion roller 22 and meshing with the drive gear 242, and a drive gear 244 mounted on the gripping roller 21 and meshing with the drive gear 242. The drive gears 243 and 244 are used to rotate in the same direction in coordination with the drive gear 242.

[0033] The adjustment component 25 includes an electric push rod 251 mounted on the equipment housing 1 to provide power, a connecting block 252 mounted on the drive end of the electric push rod 251 to move up and down in coordination with the drive of the electric push rod 251, and a rotating block 253 mounted on both ends of the extrusion roller 23 and rotatably connected to the connecting block 252 to serve as a connection. The connecting block 252 is equipped with a pressure sensor to detect the pressure of the connecting block 252 on the rotating block 253, thereby reflecting the pressure value of the extrusion roller 23 on the flax stalk and preventing overpressure or insufficient pressure on the flax stalk. The telescopic groove 11 is provided with a telescopic groove 11 that cooperates with the connecting block 252, which is used to limit the sliding of the connecting block 252, so that the up and down movement of the connecting block 252 is more stable.

[0034] The conveying unit 3 includes a motor 31 mounted on the equipment housing 1 to provide power, a connecting shaft 32 mounted on the drive end of the motor 31 to rotate in coordination with the motor 31, a transmission gear 33 mounted on the connecting shaft 32 to rotate in coordination with the connecting shaft 32, and a conveying gear 34 rotatably mounted on the fixed plate 41 and meshing with the transmission gear 33 to rotate in coordination with the transmission gear 33. Each set of transmission gears 33 has two sets of conveying gears 34 meshing with it. All conveying gears 34 are kept on the same horizontal plane. The highest point of the conveying gear 34 is higher than the highest point of the fixed plate 41. With this arrangement, the conveying gear 34 can smoothly receive and convey flax stalks. The fixed plate 41 is provided with a connecting groove 411 that matches the conveying gear 34, which is used to support the conveying gear 34.

[0035] The rest of the structure is the same as in Example 1.

[0036] In summary, firstly, motor 241 is started, which drives drive gears 243 and 244 to rotate via drive gear 242, thereby driving the gripping roller 21 and the extrusion roller 22 to rotate. At this time, the gripping roller 21 rotates and grips the flax stalks to the extrusion roller 22 for conveying. Then, electric push rod 251 is started, which drives the extrusion roller 23 to move up and down via connecting block 252, crushing the passing flax stalks in conjunction with the extrusion roller 22. The crushed flax stalks are then conveyed onto the conveying gear 34 via the extrusion roller 22. At this time, motor 31... Upon startup, the transmission gear 33 drives the conveying gear 34 to rotate, receiving flax stalks and moving them above the fixed plate 41. At this time, the second drive component 43 starts, driving the kneading component 42 to approach the fixed plate 41 and squeeze the flax stalks, causing the flax stalks to crack laterally relative to the flax fibers. Then, the second drive component 43 drives the kneading component 42 to move back and forth laterally relative to the flax stalks, working with the fixed plate 41 to knead the flax stalks. Through the mutual friction between the flax stalks, the fiber layer and the wood layer are fully separated.

[0037] Example 3, referring to Figures 1-10 This is the second embodiment of the present invention. Unlike the previous embodiment, it provides a specific structure for the deep processing unit 4 in the flax stalk crushing device. Compared to embodiment 2, the fixing plate 41 is further provided with a wavy surface 412. The wavy pattern on the wavy surface 412 is aligned with the transverse direction of the flax stalk, and a groove 413 is provided on the wavy surface 412 to increase the friction between the wavy surface 412 and the flax stalk.

[0038] The kneading assembly 42 includes a movable plate 421 mounted on the outer casing 1, which serves as a connector and is used to move in conjunction with the drive assembly 43; a kneading plate 422 mounted on the movable plate 421, which moves in conjunction with the movable plate 421 to squeeze and knead the flax stalks on the fixed plate 41; and a connecting spring 423 mounted between the movable plate 421 and the kneading plate 422, which serves as a connector to ensure that the kneading plate 422 and the flax stalks are fully squeezed together, while preventing excessive squeezing of the flax stalks that could damage the fibers. The movable plate 421 is provided with a sliding groove 4212, and the kneading plate 422 is provided with a slider 4223 that cooperates with the sliding groove 4212. The sliding groove 4212 and the slider 4223 make the kneading plate 422 move up and down on the movable plate 421 in a limited manner. The kneading board 422 is also provided with a telescopic cavity 4224 that cooperates with the connecting spring 423 for compression and release.

[0039] Among them, multiple sets of connecting shafts 4211 are provided on both sides of the movable plate 421 that are attached to the inner wall of the equipment shell 1. This arrangement maintains the stability of the movable plate 421 during movement. The equipment shell 1 is provided with a drive groove 12 that cooperates with the connecting shafts 4211. The connecting shafts 4211 cooperate with the drive groove 12 and are driven by the drive assembly 43 to make the movable plate 421 move according to the trajectory of the drive groove 12. The drive groove 12 includes an upper groove 121 disposed on the equipment housing 1, an arc-shaped groove 122 disposed on one end of the upper groove 121 and communicating with the upper groove 121, a lower groove 123 disposed on one end of the arc-shaped groove 122 and communicating with the arc-shaped groove 122, and an arc-shaped groove 124 disposed on the equipment housing 1 and communicating with the upper groove 121 and the lower groove 123 at both ends respectively. When the connecting shaft 4211 is on the upper groove 121, the kneading board 422 is not in contact with the flax stalk. When the connecting shaft 4211 enters the arc-shaped groove 122 from the upper groove 121, the arc-shaped groove 122 generates a downward force on the connecting shaft 4211, causing the kneading assembly 42 to move downward as a whole. The movement causes the wave surface 412 and the rubbing plate 422 to align, squeezing the flax stalks and causing them to crack laterally. When the connecting shaft 4211 moves to the bottom of the arc groove 122, the connecting spring 423 is compressed, causing the rubbing plate 422 to fully adhere to the flax stalks. When the connecting shaft 4211 moves from the arc groove 122 into the lower groove 123, the rubbing plate 422 slides laterally relative to the flax stalks on the fixed plate 41, rubbing the flax stalks and separating the fiber layer and wood layer. The direction of movement of the connecting shaft 4211 on the lower groove 123 is consistent with the conveying direction of the conveying gear 34.

[0040] The rubbing board 422 is provided with a second wave surface 4221 and a protrusion 4222 that cooperate with the first wave surface 412 and the groove 413. Through the cooperation of the first wave surface 412 and the groove 413, the flax stalks are crushed in the transverse direction. The groove 413 and the protrusion 4222 further increase the friction between the first wave surface 412 and the second wave surface 4221 on the flax stalks. The second wave surface 4221 moves back and forth on the first wave surface 412 to rub the flax stalks, which further breaks down the wood layer and fully separates the wood layer and the fiber layer.

[0041] The second drive assembly 43 includes an electric push rod 431 mounted on the housing 1 for providing power, a drive block 432 mounted on the drive end of the electric push rod 431 for telescopic movement in coordination with the electric push rod 431, and a fixed block 433 mounted on the drive block 432 and fixedly connected to the movable plate 421 for cooperating with the push and pull of the drive block 432 to drive the movable plate 421 to move along the trajectory of the drive groove 12. The outer casing 1 of the equipment is provided with a sliding groove 13 that cooperates with the drive block 432 and the fixed block 433 for the back and forth movement of the drive block 432 and the fixed block 433. The drive block 432 is provided with a support slider 4321, and the sliding groove 13 is provided with a support groove 131 that cooperates with the support slider 4321. The electric push rod 431 cooperates with the support slider 4321 to provide sliding support for the drive block 432. The driving block 432 is provided with a connecting slider 4322, and the fixed block 433 is provided with a connecting groove 4331 that cooperates with the connecting slider 4322. Through the cooperation of the connecting slider 4322 and the connecting groove 4331, the fixed block 433 can slide up and down on the driving block 432 in accordance with the trajectory of the driving groove 12.

[0042] The rest of the structure is the same as in Example 2.

[0043] In summary, when the conveying gear 34 receives the flax stalks and conveys them onto the wave surface 412, the electric push rod 431 is activated, causing the drive block 432 to extend forward. The distance it moves is the furthest distance from the arc groove 124 to both sides of the arc groove 122. At this time, the fixed block 433 drives the kneading assembly 42 to move in coordination with the connecting shaft 4211 and the drive groove 12. When the connecting shaft 4211 slides in the upper groove 121, the movable plate 421 drives the kneading plate 422 to move in the opposite direction of the conveying gear 34. The connecting shaft 4211 moves from the upper groove 121 into the arc-shaped groove 122. At this time, the arc-shaped groove 122 exerts a downward force on the connecting shaft 4211, which drives the movable plate 421 to move downward. At this time, the fixed block 433 slides down relative to the driving block 432. The rubbing plate 422 moves downward and begins to contact the flax stalks on the fixed plate 41. In conjunction with the movement of the connecting shaft 4211 in the arc-shaped groove 122, it squeezes the flax stalks. At this time, the connecting spring 423 cooperates with the force generated by squeezing the flax stalks. Compression is applied, causing the protrusion 4222 to fully align with the corrugated surface 412, resulting in transverse cracking of the flax stalks and further accelerating the separation of the woody and fiber layers. At this time, the connecting shaft 4211 enters the lower groove 123 through the arc-shaped groove 122. The electric push rod 431 retracts, and the movable plate 421 drives the kneading plate 422 to move horizontally relative to the fixed plate 41. Combined with the action of the protrusion 4222 and the groove 413, the compressed flax stalks are kneaded, fully separating the woody and fiber layers. When the connecting shaft 4211... When the flax stalks enter the arc-shaped groove 124 through the lower groove 123, the arc-shaped groove 124 exerts an upward force on the connecting shaft 4211. In conjunction with the contraction of the electric push rod 431, the rubbing assembly 42 moves upward as a whole. At this time, the connecting spring 423 is released, reducing the pressure on the flax stalks. This continues until the connecting shaft 4211 re-enters the upper groove 121 through the arc-shaped groove 124. At this point, the protrusion 4222 is no longer in contact with the flax stalks. Through the fixed plate 41 and the rubbing assembly 42, the flax stalks are continuously processed under the continuous conveying of the conveying gear 34.

[0044] 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 it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
