Description

Technical Field

[0001] This utility model belongs to the field of flax short fiber processing technology, and relates to a flax short fiber pretreatment device. Background Technology

[0002] Flax staple fiber is a byproduct separated during the flax processing step, mainly produced from lower-quality dried stems or coarse flax. Because flax staple fibers are encased in gums and natural impurities, direct spinning can lead to fiber breakage and excessive yarn fuzz. Therefore, a crushing process is necessary to loosen the fibers and remove impurities.

[0003] A pretreatment device for flax short fibers disclosed in Chinese patent CN217249252U includes an automatic discharge mechanism comprising a guide hopper fixedly installed on the inner wall of the bottom of a treatment box, a discharge frame fixedly fitted to the bottom of the treatment box, and two symmetrically distributed shells fixedly connected to the inner wall of the bottom of the treatment box. An electromagnet and several limiting springs are fixedly connected to the inner wall of one side of the shell, and a baffle is fixedly connected to the other end of the limiting spring. A magnetic sheet is embedded in the side of the baffle near the electromagnet, and the electromagnet and the magnetic sheet have the same magnetic poles.

[0004] The processing device drops the processed material downward through the guide hopper. However, during discharge, some material tends to stick to the inner wall of the guide hopper, resulting in material residue and waste.

[0005] To address the aforementioned problems, this invention proposes a pretreatment device for flax short fibers. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a pretreatment device for flax short fibers.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a processing box, two cover plates are rotatably arranged at the feed inlet at the top of the processing box, a crushing component is rotatably arranged in the middle of the processing box, and two guide plates are symmetrically fixedly connected to the bottom of the processing box. The top surfaces of the two guide plates are inclined surfaces, and a scraper is slidably arranged on the top surface of each guide plate.

[0008] The bottom surface of the processing box is symmetrically and horizontally limited by two baffles, two cover plates, two guide plates, and two baffles that correspond one to the other. Each cover plate is provided with a first transmission component. When the cover plate rotates, the first transmission component drives the corresponding baffle to slide horizontally. Both baffles are provided with a second transmission component. When the baffle slides, the second transmission component drives the corresponding guide plate to slide.

[0009] Furthermore, mounting plates are fixedly connected to the four corners of the top surface of the feed inlet at the top of the processing box. Each pair of mounting plates forms a group, and the same connecting shaft is rotatably connected to the two mounting plates in each group. The connecting shaft is horizontally arranged, and the two cover plates are respectively fixedly sleeved on the two connecting shafts. The cover plates are rotatably positioned between the corresponding two mounting plates.

[0010] Furthermore, the crushing assembly includes two crushing rollers, both of which are rotatably connected to the inside of the processing chamber. The central axes of the two crushing rollers are on the same horizontal plane, and the feed inlet at the top of the processing chamber is located directly above the two crushing rollers.

[0011] Furthermore, the two crushing rollers correspond one-to-one with the two guide plates, and there is a distance between the two guide plates. The feed inlet at the top of the processing box is located directly above the two guide plates, and the inclined surface of the guide plates gradually slopes upward from the side where the two guide plates are close to each other.

[0012] Furthermore, the first transmission component includes a belt, and connecting plates are fixedly connected to the four corners at the bottom of the processing box. Two connecting plates located on the same side of the processing box form a group, and the baffle is located between the two connecting plates in the same group.

[0013] Two connecting plates in the same group are rotatably connected to a rotating shaft on their adjacent sides. One end of each rotating shaft is fixedly fitted with a one-way bearing on one end of the connected connecting plate. A turntable is fixedly fitted on the other end of each rotating shaft. A push rod is eccentrically fixedly connected to one side of each turntable. Two end plates on the opposite sides of the two baffles are fixedly connected with a slot plate. The push rod is slidably connected in the corresponding slot plate.

[0014] Each of the connecting shafts is fixedly connected to two ends with a first pulley, and each one-way bearing is fixedly fitted with a second pulley. The belt drive is fitted onto the corresponding first and second pulleys.

[0015] Furthermore, the second transmission component includes two first racks, which are respectively fixedly connected to two ends of the top surface of the baffle;

[0016] Each guide plate has a partition plate fixedly connected to both ends of its top surface. The scraper is slidably connected between the two corresponding partition plates. A second toothed rack is slidably connected to the bottom of each partition plate. The scraper is fixedly connected between the two corresponding second toothed racks. The connection between the scraper and the second toothed rack slides through the corresponding partition plate.

[0017] Each guide plate has a gear rotatably connected to both ends, and the gear meshes with the corresponding first rack and second rack.

[0018] Furthermore, the bottom surface of the processing box is provided with a discharge port between two guide plates, and the two baffles are slidably disposed in the discharge port.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The flax short fiber pretreatment device is equipped with a scraper, which is slidably mounted on the top of the guide plate. Since the crushed material falls downward onto the guide plate and then slides down along the inclined surface of the guide plate, the scraper can push the material stuck on the guide plate to move by sliding on the top of the guide plate, thereby removing more material and reducing waste.

[0021] 2. The flax short fiber pretreatment device is equipped with a belt. When the cover plate is rotated, the rotation of the first pulley will drive the rotation of the second pulley through the belt, thereby driving the baffle to move and causing the material to fall downward. At the same time, it will drive the scraper to slide on the guide plate. No separate operation is required, making it convenient to use. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A flax short fiber pretreatment device includes a treatment box 1, and two cover plates 2 are rotatably installed at the feed inlet at the top of the treatment box 1. When both cover plates 2 are rotated to a horizontal state, the feed inlet at the top of the treatment box 1 is sealed.

[0030] Mounting plates 16 are fixedly connected to the four corners of the top surface of the feed inlet at the top of the processing box 1. Each pair of mounting plates 16 forms a group, and the two mounting plates 16 in each group are located at the two ends of the same side of the top of the processing box 1.

[0031] The same connecting shaft rotatably passes through the two mounting plates 16 in each group, and the connecting shaft is horizontally arranged. Two cover plates 2 are respectively fixedly sleeved on the two connecting shafts, and the cover plates 2 are rotatably positioned between the corresponding two mounting plates 16. This allows the rotating end of the cover plate 2 to be positioned on the side of the top of the processing box 1, so that the cover plate 2 can be rotated away from the feed inlet of the processing box 1, and flax short fiber material can be added into the processing box 1 through the feed inlet.

[0032] A crushing component is rotatably installed in the middle of the processing box 1.

[0033] The crushing assembly includes two crushing rollers 15. Both crushing rollers 15 are rotatably connected inside the processing chamber 1, and their central axes are on the same horizontal plane. The feed inlet at the top of the processing chamber 1 is located directly above the two crushing rollers 15. This allows material fed through the feed inlet to fall onto the crushing rollers 15, enabling direct crushing.

[0034] Both connecting shafts and both crushing rollers 15 are externally connected to drive motors. The crushing rollers 15 are directly connected to the output shafts of the external motors, which enable the crushing rollers 15 to rotate. The two connecting shafts are connected to the external motors via gear transmission. Specifically, gears are fixedly fitted on both the output shaft of the external motor and the connecting shafts, and the external motors drive the connecting shafts to rotate via gear transmission.

[0035] Two guide plates 14 are symmetrically fixedly connected to the bottom of the processing box 1, and the top surfaces of the two guide plates 14 are inclined surfaces.

[0036] Two crushing rollers 15 correspond one-to-one with two guide plates 14, with a distance between the two guide plates 14. The feed inlet at the top of the processing box 1 is located directly above the two guide plates 14, and the inclined surface of the guide plates 14 gradually slopes upward from the side where the two guide plates 14 are close to each other. This allows the material crushed by the crushing rollers 15 to fall directly between the two guide plates 14.

[0037] Each guide plate 14 has a scraper 12 slidably mounted on its top surface. The scraper 12 slides on the inclined surface of the guide plate 14, such that the sliding direction of the scraper 12 is consistent with the inclination direction of the inclined surface.

[0038] The bottom surface of the processing box 1 is symmetrically and horizontally limited by two baffles 7, two cover plates 2, two guide plates 14, and two baffles 7 corresponding one above the other. This allows the baffles 7 to slide at the bottom of their corresponding guide plates 14.

[0039] The bottom surface of the processing box 1 has a discharge port located between two guide plates 14, and two baffles 7 are slidably disposed inside the discharge port. When both baffles 7 are slid into the discharge port, they can block the discharge port.

[0040] Each cover plate 2 is equipped with a first transmission component. When the cover plate 2 rotates, the first transmission component drives the corresponding baffle 7 to slide horizontally.

[0041] The first transmission component includes a belt 5. Connecting plates 17 are fixedly connected to the four corners of the bottom of the processing box 1. Two connecting plates 17 located on the same side of the processing box 1 form a group. A baffle 7 is located between two connecting plates 17 in the same group, allowing the baffle 7 to slide between corresponding connecting plates 17.

[0042] Two connecting plates 17 in the same group are rotatably connected to a rotating shaft on their adjacent sides. A one-way bearing 18 is fixedly fitted onto one end of each rotating shaft near the connected connecting plate 17. A turntable 6 is fixedly fitted onto the other end of each rotating shaft, and a push rod 19 is eccentrically fixedly connected to one side of each turntable 6. Two slotted plates 8 are fixedly connected to the two ends of the two baffles 7 on their opposite sides, and the push rod 19 is slidably connected within the corresponding slotted plate 8. The push rod 19 is horizontally positioned, while the slots within the slotted plates 8 are vertically positioned, allowing the push rod 19 to slide within the slotted plates 8 as the turntable 6 rotates, simultaneously pushing the slotted plates 8 to move horizontally back and forth.

[0043] Each connecting shaft has a first pulley 3 fixedly connected to both ends, and a second pulley 4 fixedly mounted on each one-way bearing 18. A belt 5 is driven onto the corresponding first pulley 3 and second pulley 4, causing the first pulley 3 to drive the second pulley 4 to rotate. The diameter of the first pulley 3 is twice the diameter of the second pulley 4, so that when the first pulley 3 rotates 180 degrees, the second pulley 4 rotates 360 degrees.

[0044] Both baffles 7 are equipped with second transmission components. When the baffles 7 slide, the second transmission components drive the corresponding guide plates 14 to slide.

[0045] The second transmission component includes two first racks 9, which are fixedly connected to the two ends of the top surface of the baffle 7. This causes the baffle 7 to drive the two first racks 9 to slide horizontally back and forth.

[0046] Each guide plate 14 has a partition plate 13 fixedly connected to both ends of its top surface, and a scraper 12 is slidably connected between the two corresponding partition plates 13. The partition plates 13 are arranged along the inclined direction of the top surface of the guide plate 14.

[0047] Each partition 13 has a second rack 11 slidably connected to its bottom, and a scraper 12 is fixedly connected between two corresponding second racks 11. The connection between the scraper 12 and the second rack 11 slides through the corresponding partition 13. The partition 13 restricts the movement of the scraper 12, allowing the scraper 12 to slide on the inclined surface of the guide plate 14.

[0048] Each guide plate 14 has a gear 10 rotatably connected to both ends, and the gear 10 meshes with the corresponding first rack 9 and second rack 11. Through the transmission of the gear 10, the movement of the first rack 9 will drive the movement of the second rack 11.

[0049] Working principle:

[0050] In use, start the external motor on the connecting shaft to make the connecting shaft rotate, and the two connecting shafts rotate in opposite directions. The connecting shaft drives the cover plate 2 to rotate, so that the two cover plates 2 rotate in opposite directions.

[0051] The two cover plates 2 are moved apart at their closest ends, thus opening the feed port at the top of the processing box 1. The connecting shaft simultaneously drives the first pulley 3 to rotate, and the first pulley 3 drives the corresponding second pulley 4 to rotate via the belt 5. At this time, the one-way bearing 18 is locked, and the one-way bearing 18 drives the rotating shaft to rotate, causing the turntable 6 and the push rod 19 to rotate.

[0052] Push rod 19 rotates around the rotation axis of turntable 6, pushing the slot plate 8 to move while simultaneously sliding within the slot plate 8. The slot plate 8 then moves the baffle 7, causing the two baffles 7 to move away from each other.

[0053] The baffle 7 drives the first rack 9 to move, the first rack 9 drives the gear 10 to rotate, and the gear 10 drives the second rack 11 to move. The second rack 11 drives the scraper 12 to slide on the top surface of the guide plate 14, and the scraper 12 slides downward along the inclined surface.

[0054] Since the diameter of the first pulley 3 is twice the diameter of the second pulley 4, when the first pulley 3 rotates 180 degrees, the second pulley 4 rotates 360 degrees. Therefore, when the cover plate 2 rotates 90 degrees, the scraper 12 slides to the bottom of the inclined surface. Afterward, as the cover plate 2 continues to rotate, the push rod 19 pushes the two baffles 7 closer together, causing the scraper 12 to slide upwards along the inclined surface. When the cover plate 2 rotates 180 degrees, the scraper 12 slides to the top of the inclined surface.

[0055] The flax short fiber material to be processed is placed into the processing box 1 between the two cover plates 2 and falls between the two crushing rollers 15.

[0056] Then, the external power supply drives the connecting shaft to rotate, rotating the cover plate 2 to the top surface of the processing box 1. This brings the two cover plates 2 closer together, sealing the feed inlet at the top of the processing box 1. At this time, the one-way bearing 18 rotates freely, the shaft does not rotate, and the baffle 7 and scraper 12 do not move.

[0057] Turn on the external power supply on the crushing roller 15 to make the crushing roller 15 rotate, and the two crushing rollers 15 rotate in opposite directions. The two crushing rollers 15 crush the material, and the crushed material falls down onto the guide plate 14, and then slides onto the two baffles 7.

[0058] After the material is crushed, the cover plate 2 is opened again. Similarly, this will drive the two baffles 7 to move away from each other, causing the material to fall downwards. At the same time, the scraper 12 will slide on the inclined surface of the guide plate 14, pushing the material stuck to the inclined surface downwards, reducing material residue in the processing box 1 and reducing waste.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
