[0001] This invention relates to the field of nylon production technology, specifically to an apparatus and method for producing nylon staple fiber for nonwoven fabrics. Background Technology

[0002] The nonwoven fabric nylon staple fiber production equipment is mainly used to produce nylon staple fibers, which can be used to manufacture nonwoven fabrics.

[0003] Patent publication number CN215251357U relates to a production device for nylon staple fiber in nonwoven fabrics, including a box, a sealing plate, and a placement plate. Motors are fixedly installed on both sides inside the box. Hollow plates are movably installed at both ends of the top of the placement plate via sliders. An electric push rod is fixedly installed inside the box on one side of the placement plate. A slot is fixedly installed on the outer surface of the limiting plate surrounding the clamp. A sealing plate is movably installed on the surface of the other side of the box. A top rod is movably installed on one side of the sealing plate. A limiting groove is fixedly installed on the outer surface of the limiting plate on one side of the top rod, and the limiting groove corresponds to the top rod. This patent, through a series of structures, enables the device to automatically perform oiling production of nylon staple fiber during use and can automatically push it out of the device for unloading. During unloading, the opening can be automatically opened and sealed without the need for power.

[0004] In the aforementioned patent, a series of structures are set up so that the device can automatically perform oiling production of nylon staple fiber during use, and can automatically eject the fiber from the device for unloading. During unloading, the opening can be automatically opened and sealed without the need for electricity. However, when extruding and shaping the raw material, too much raw material will cause the subsequent shaping to be insufficiently extruded, resulting in the shaping not meeting the required requirements and wasting raw materials. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an apparatus and method for producing nylon staple fibers for nonwoven fabrics, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a nonwoven fabric nylon staple fiber production device, including a support frame, a conveyor plate fixedly installed on the top of the support frame, a baffle plate fixedly installed on the top of the conveyor plate, a cabinet fixedly installed on the bottom of the support frame, and a feeding device, a control device, and a positioning device provided on the top of the cabinet.

[0007] The feeding device includes: a conveyor box, a feed box, a guide plate, an inclined plate, a support plate, a rotating shaft, a clamping plate one, a clamping plate two, a through rod, a fixing component, a sliding plate, and an arc plate. The conveyor box is fixedly installed on the top of the support frame, and the feed box is fixedly installed on the side of the conveyor box away from the cabinet. The guide plate is slidably installed on the inner wall of the feed box, the inclined plate is rotatably installed on the inner wall of the feed box, the support plate is fixedly installed on the inner wall of the feed box, the rotating shaft is rotatably installed on both sides of the inner wall of the feed box, the clamping plate one is fixedly installed on the bottom of the guide plate, the clamping plate two is fixedly installed on the bottom of the inclined plate, and the through rod is fixedly inserted through the inner wall of the rotating shaft. On the outer wall, one end of the through rod is rotatably mounted on clamping plate one, and the other end of the through rod is rotatably mounted on the surface of clamping plate two. The fixing member is fixedly mounted on the surface of the conveyor box, and the sliding plate is slidably mounted on the inner wall of the fixing member. The arc plates are all fixedly mounted on both ends of the sliding plate. The guide plate is moved to the top by the reset of spring number one. The movement of the guide plate to the top will cause clamping plate one to move to the top. The movement of clamping plate one to the top will cause the through rod to rotate to the top. The rotation of the through rod to the top will cause the rotating shaft to rotate. The rotation of the through rod to the top will cause clamping plate two to move to the top. The movement of clamping plate two to the top will cause the inclined plate to rotate to the bottom.

[0008] According to the above technical solution, a No. 1 spring is provided between the support plate and the guide plate. The guide plate contacts the arc plate, and the No. 1 spring drives the guide plate to reset.

[0009] According to the above technical solution, the control device includes: a servo motor, a first roller, a control button, a cover plate, and a second roller. The servo motor is fixedly installed on the side of the conveyor box away from the fixed component. The first roller is rotatably installed on the inner wall of the conveyor box. The output end of the servo motor is fixedly installed on the surface of the first roller. The control button is fixedly installed on the surface of the conveyor box and electrically connected to the servo motor. The surface of the control button is provided with multiple control terminals. The bottom control terminal is a shut-off button, and the top button is a start button. The cover plate is fixedly installed on the top of the conveyor box. The second roller is rotatably installed on the inner wall of the conveyor box. When the control button is pressed, the control button starts the servo motor. The rotation of the output end of the servo motor drives the first roller to rotate. The rotation of the first roller compresses the raw material. After being compressed, the raw material moves towards the conveyor plate through the rotation of the first and second rollers.

[0010] According to the above technical solution, the control device further includes: a collar, an L-shaped rod, a transmission block, a button box, a button plate, and a triangular block. The collar is rotatably mounted on the circumferential surface of the roller two. The L-shaped rod rotatably passes through the inner and outer walls of the conveyor box. The L-shaped rod is fixedly mounted on the circumferential surface of the collar. The transmission block is fixedly mounted on the end of the L-shaped rod away from the collar. The button box is fixedly mounted on the surface of the control button. The button plate is slidably mounted on the inner wall of the button box. The triangular block slidably passes through the inner and outer walls of the button box. When the transmission block moves to the bottom, it drives the triangular block to move into the button box. When the triangular block moves, it drives the button plate to move in the direction of the control button. When the button plate moves, it presses the bottommost button, causing the output end of the servo motor to stop rotating.

[0011] According to the above technical solution, the transmission block is in contact with the triangular block, and a second spring is provided between the button plate and the button box. The button plate is reset by the second spring.

[0012] According to the above technical solution, the positioning device includes: a vertical plate, a belt, a lead screw, a ring, a telescopic rod, and a positioning plate. The vertical plate is fixedly installed on the inner wall of the conveyor box. The lead screw is rotatably installed between the conveyor box and the vertical plate. The lead screw and the roller are connected by belt drive. A reciprocating spiral groove is formed on the surface of the lead screw. The ring is slidably installed inside the reciprocating spiral groove. The telescopic rod is fixedly installed on the circumferential surface of the ring. The positioning plate is fixedly installed at the bottom of the free end of the telescopic rod. The reciprocating movement of the ring will drive the telescopic rod to reciprocate, which in turn will drive the positioning plate to reciprocate. The reciprocating movement of the positioning plate will push the processed raw material.

[0013] According to the above technical solution, the positioning device further includes: a long rod, a rotating arc rod, and a blocking plate. The long rod is fixedly installed on the inner wall of the conveyor box, the rotating arc rod is rotatably installed on the surface of the long rod, and the blocking plate is fixedly installed at the bottom of the long rod. After the positioning plate contacts the rotating arc rod, the rotating arc rod is blocked by the blocking plate, so that the rotating arc rod cannot rotate to the bottom. After the rotating arc rod cannot rotate to the bottom, it will drive the positioning plate to move to the top through its own arc design.

[0014] According to the above technical solution, a torsion spring is provided between the rotating arc rod and the long rod, and the positioning plate contacts the rotating arc rod, so that the rotating arc rod is reset by the torsion spring.

[0015] A method of using an apparatus for producing nylon staple fiber for nonwoven fabrics includes the following steps;

[0016] Step 1: Pour the raw material into the feed box. The raw material slides to the bottom through the guide plate. After leaving the guide plate, the raw material continues to flow to the bottom along the inclined plate and then flows into the interior of the conveyor box.

[0017] Step 2: When too much raw material is piled up on top of the guide plate, the increased weight of the piled-up material will compress and drive the guide plate to move to the bottom. The movement of the guide plate to the bottom will drive the clamping plate to move to the bottom as well.

[0018] Step 3: The movement of clamp one to the bottom will cause the through rod to rotate to the bottom, the rotation of the through rod to the bottom will cause the pivot to rotate, the rotation of the through rod to the bottom will cause clamp two to move to the top, and the movement of clamp two to the top will cause the inclined plate to rotate to the top.

[0019] Step 4: After the inclined plate rotates to the top, it will come into contact with the guide plate. After the inclined plate comes into contact with the guide plate, the gap between the inclined plate and the guide plate is reduced, which makes it impossible for the raw material to continue to flow to the bottom through the originally set gap. This makes it impossible to continuously transport the raw material when too much material accumulates.

[0020] This invention provides an apparatus and method for producing nylon staple fiber for nonwoven fabrics. It has the following beneficial effects:

[0021] (1) In this invention, after the inclined plate comes into contact with the guide plate, the gap between the inclined plate and the guide plate is reduced, so that the raw material cannot continue to flow to the bottom through the originally set gap. This prevents the raw material from being continuously transported when there is too much raw material. This prevents the raw material from being insufficiently squeezed during subsequent shaping due to excessive raw material input, thus preventing shaping failure and material waste. After the inclined plate rotates, the device returns to its original setting, so that the feeding is automatically controlled in real time according to the degree of raw material accumulation. No manual operation is required, reducing manual input and increasing the precision of operation.

[0022] (2) In this invention, the raw material is squeezed and then moved towards the conveyor plate by the rotation of roller one and roller two. The cooled raw material is stretched to improve its strength and uniformity, which facilitates subsequent processing. The movement of the plate will press the bottom button, which will stop the output end of the servo motor from rotating. The remaining amount of raw material will drive the plate to press different buttons. The device can be automatically shut down after the raw material processing is completed, reducing energy consumption.

[0023] (3) In this invention, the reciprocating movement of the telescopic rod will drive the positioning plate to reciprocate. The reciprocating movement of the positioning plate will push the processed raw material, preventing the raw material from being squeezed and extending to both sides, thus preventing it from moving normally towards the conveying plate. This improves the stability of the device during operation. When the rotating arc rod cannot rotate to the bottom, it will drive the positioning plate to the top through its own arc design. This allows the positioning plate to be lifted to the top and not in contact with the raw material when it moves away from the raw material, preventing the positioning plate from sticking to the raw material after contact, thus preventing damage to the raw material and improving the practicality of the device.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-7One embodiment of the present invention is: a production device for nylon staple fiber for nonwoven fabrics, comprising a support 1, a conveyor plate 4 fixedly installed on the top of the support 1, a baffle plate 2 fixedly installed on the top of the conveyor plate 4, a cabinet 3 fixedly installed on the bottom of the support 1, and a feeding device provided on the top of the cabinet 3. The feeding device includes: a conveyor box 51, a feeding box 52, a guide plate 53, an inclined plate 54, a support plate 55, a rotating shaft 57, a clamping plate 1 58, a clamping plate 2 59, and a through rod 510. The system includes a fixing component 511, a sliding plate 512, and an arc plate 513. The conveyor box 51 is fixedly installed on the top of the bracket 1. The feed box 52 is fixedly installed on the side of the conveyor box 51 away from the cabinet 3. The guide plate 53 is slidably installed on the inner wall of the feed box 52. The inclined plate 54 is rotatably installed on the inner wall of the feed box 52. The support plate 55 is fixedly installed on the inner wall of the feed box 52. The rotating shaft 57 is rotatably installed on both sides of the inner wall of the feed box 52. The clamping plate 58 is fixedly installed at the bottom of the guide plate 53. The clamping plate 59 is fixedly installed at the bottom of the inclined plate 54. The through rod 510 is fixedly installed through the inner and outer walls of the rotating shaft 57. One end of the through rod 510 is rotatably installed on the clamping plate 58, and the other end of the through rod 510 is rotatably installed on the surface of the clamping plate 59. This prevents the raw material from continuing to flow to the bottom through the originally set gap. This prevents the continuous conveying of raw material when too much raw material accumulates. This prevents the subsequent shaping process from being unable to fully compress the raw material due to excessive raw material input, resulting in shaping failure and material waste. The fixing part 511 is fixedly installed on the surface of the conveying box 51. The sliding plate 512 is slidably installed on the inner wall of the fixing part 511. The arc plates 513 are fixedly installed at both ends of the sliding plate 512. After the inclined plate 54 is rotated, the device returns to its original setting, so that the feeding is automatically controlled in real time according to the degree of raw material accumulation. There is no need for manual operation, reducing labor input and increasing the precision of operation.

[0034] A first spring 56 is provided between the support plate 55 and the guide plate 53. The guide plate 53 contacts the arc plate 513, and the guide plate 53 is reset by the first spring 56.

[0035] A method of using an apparatus for producing nylon staple fiber for nonwoven fabrics includes the following steps;

[0036] Step 1: Pour the raw material into the feed box 52. The raw material slides to the bottom through the guide plate 53. After leaving the guide plate 53, the raw material continues to flow to the bottom along the inclined plate 54 and then flows into the interior of the conveyor box 51.

[0037] Step 2: When too much raw material accumulates on top of the guide plate 53, the increased weight of the accumulated raw material will cause it to squeeze and move the guide plate 53 to the bottom. The movement of the guide plate 53 to the bottom will cause the clamping plate 58 to move to the bottom.

[0038] Step 3: When clamp 1 58 moves to the bottom, it will cause the through rod 510 to rotate to the bottom. When the through rod 510 rotates to the bottom, it will cause the rotating shaft 57 to rotate. When the through rod 510 rotates to the bottom, it will cause clamp 2 59 to move to the top. When clamp 2 59 moves to the top, it will cause the inclined plate 54 to rotate to the top.

[0039] Step 4: After the inclined plate 54 rotates to the top, it will come into contact with the guide plate 53. After the inclined plate 54 comes into contact with the guide plate 53, the gap between the inclined plate 54 and the guide plate 53 is reduced, so that the raw material cannot continue to flow to the bottom through the originally set gap, so that when too much raw material is accumulated, the raw material cannot be continuously transported.

[0040] In this embodiment, during operation: raw materials are poured into the feed box 52. The raw materials slide to the bottom through the guide plate 53. After leaving the guide plate 53, the raw materials continue to flow to the bottom along the inclined plate 54, and then flow into the interior of the conveying box 51. When too much raw material accumulates on top of the guide plate 53, the increased weight of the accumulated material will compress and drive the guide plate 53 to move to the bottom. The movement of the guide plate 53 to the bottom will drive the clamping plate 58 to move to the bottom. The movement of the clamping plate 58 to the bottom will drive the through rod 510 to rotate to the bottom. The rotation of the through rod 510 to the bottom will drive the rotating shaft 57 to rotate. The rotation of the through rod 510 to the bottom will drive the clamping plate 59 to move to the top. The movement of the clamping plate 59 to the top will drive the inclined plate 54 to rotate to the top. After the inclined plate 54 rotates to the top, it will contact the guide plate 53. After the inclined plate 54 contacts the guide plate 53, the gap between the inclined plate 54 and the guide plate 53 will decrease, making it impossible for the raw material to pass through the originally set gap. The material continues to flow to the bottom, preventing continuous feeding when there is excessive material accumulation. This prevents insufficient material compression during subsequent shaping, thus avoiding material waste. As the material decreases, spring 56 resets and moves guide plate 53 to the top. This movement causes clamping plate 58 to move to the top, which in turn causes through rod 510 to rotate. This rotation causes shaft 57 to rotate, which in turn causes clamping plate 59 to move to the top. This rotation causes inclined plate 54 to rotate to the bottom. After inclined plate 54 rotates, the device returns to its original setting. This allows for automatic feeding control based on the material accumulation level, eliminating the need for manual operation, reducing labor input, and increasing operational precision.

[0041] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a control device and a positioning device are provided on the top of the cabinet 3. The control device includes: a servo motor 61, a first roller 62, a control button 63, a cover plate 64, and a second roller 65. The servo motor 61 is fixedly installed on the side of the conveyor box 51 away from the fixing member 511. The first roller 62 is rotatably installed on the inner wall of the conveyor box 51. The output end of the servo motor 61 is fixedly installed on the surface of the first roller 62. The control button 63 is fixedly installed on the surface of the conveyor box 51 and is electrically connected to the servo motor 61. The cover plate 64 is fixedly installed on the top of the conveyor box 51. The second roller 65 is rotatably installed on the inner wall of the conveyor box 51 to stretch the cooled raw material to improve its strength and uniformity, facilitating subsequent processing.

[0042] The control device also includes: a collar 66, an L-shaped rod 67, a transmission block 68, a button box 69, a button plate 610, and a triangular block 611. The collar 66 is rotatably mounted on the circumferential surface of the roller 65. The L-shaped rod 67 rotatably passes through the inner and outer walls of the conveying box 51. The L-shaped rod 67 is fixedly mounted on the circumferential surface of the collar 66. The transmission block 68 is fixedly mounted on the end of the L-shaped rod 67 away from the collar 66. The button box 69 is fixedly mounted on the surface of the control button 63. The button plate 610 is slidably mounted on the inner wall of the button box 69. The triangular block 611 slidably passes through the inner and outer walls of the button box 69. By adjusting the remaining amount of raw material, the button plate 610 can be pressed to activate different buttons. The device can be automatically shut down after the raw material processing is completed, reducing energy consumption.

[0043] The transmission block 68 contacts the triangular block 611, and a second spring is provided between the button plate 610 and the button box 69. The button plate 610 is reset by the second spring.

[0044] The positioning device includes: a vertical plate 71, a belt 72, a lead screw 73, a ring 74, a telescopic rod 75, and a positioning plate 76. The vertical plate 71 is fixedly installed on the inner wall of the conveyor box 51. The lead screw 73 is rotatably installed between the conveyor box 51 and the vertical plate 71. The lead screw 73 and the roller 65 are connected by a belt 72. The surface of the lead screw 73 is provided with a reciprocating spiral groove. The ring 74 is slidably installed inside the reciprocating spiral groove. The telescopic rod 75 is fixedly installed on the circumference of the ring 74. The positioning plate 76 is fixedly installed at the bottom of the free end of the telescopic rod 75 to prevent the raw material from being squeezed and extending to both sides, thus preventing it from moving normally towards the conveyor plate 4 and improving the stability of the device during operation.

[0045] The positioning device also includes a long rod 77, a rotating arc rod 78, and a baffle plate 79. The long rod 77 is fixedly installed on the inner wall of the conveyor box 51, the rotating arc rod 78 is rotatably installed on the surface of the long rod 77, and the baffle plate 79 is fixedly installed at the bottom of the long rod 77. This allows the positioning plate 76 to be lifted upwards and not in contact with the raw material when it moves away from the raw material, preventing the positioning plate 76 from sticking to the raw material after contact, thus preventing damage to the raw material and improving the practicality of the device.

[0046] A torsion spring is provided between the rotating arc rod 78 and the long rod 77. The positioning plate 76 contacts the rotating arc rod 78, and the torsion spring drives the rotating arc rod 78 to reset.

[0047] In this embodiment, during operation: the guide plate 53 moves to the bottom, and its movement to the top causes the arc plate 513 to move to the top. The arc plate 513's movement to the top causes the sliding plate 512 to move to the top, and the sliding plate 512's movement to the top causes another arc plate 513 to move to the top. The movement of the arc plate 513 causes the end of roller 62 away from the servo motor 61 to rotate. Pressing the control button 63 starts the servo motor 61. The rotation of the output end of the servo motor 61 causes roller 62 to rotate, which in turn compresses the raw material. After being compressed, the raw material is moved towards the conveyor plate 4 by the rotation of roller 62 and roller 65, stretching the cooled raw material to improve its strength and uniformity, facilitating subsequent processing. After the raw material is shaped, roller 65 moves to the top. This movement causes collar 66 to move to the top, which in turn causes L-shaped rod 67 to rotate to the top. This rotation causes transmission block 68 to rotate to the bottom. This rotation causes triangular block 611 to contact the triangular block 611. This movement causes triangular block 611 to move into button box 69. This movement causes button 610 to move towards control button 63. This movement of button 610 presses the bottom control terminal of control button 63, stopping the output of servo motor 61. By controlling the remaining amount of raw material, different buttons on button 610 can be pressed. This allows the device to automatically shut down after processing, reducing energy consumption.

[0048] The rotation of roller 65 drives the lead screw 73 to rotate, which in turn drives the reciprocating spiral groove to rotate. This rotation of the spiral groove causes the ring 74 to reciprocate, which in turn drives the telescopic rod 75 to reciprocate. The reciprocating movement of the telescopic rod 75 then drives the positioning plate 76 to reciprocate. The reciprocating movement of the positioning plate 76 pushes the processed material, preventing it from being squeezed and extending to the sides, thus hindering its movement towards the conveyor plate 4 and improving the stability of the device during operation. The positioning plate 76 moves away from the material. When the positioning plate 76 moves, it will come into contact with the rotating arc rod 78. After the positioning plate 76 comes into contact with the rotating arc rod 78, the rotating arc rod 78 is blocked by the blocking plate 79, so that the rotating arc rod 78 cannot rotate to the bottom. After the rotating arc rod 78 cannot rotate to the bottom, it will drive the positioning plate 76 to move to the top through its own arc design. This will cause the positioning plate 76 to lift up and not come into contact with the raw material when it moves away from the raw material, thus preventing the positioning plate 76 from sticking to the raw material and causing damage to the raw material, thereby improving the practicality of the device.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

7. A method of using a nonwoven fabric nylon staple fiber production apparatus, comprising using the nonwoven fabric nylon staple fiber production apparatus as described in claim 6, characterized in that, Includes the following steps; Step 1: Pour the raw material into the feed box (52). The raw material slides to the bottom through the guide plate (53). After leaving the guide plate (53), the raw material continues to flow to the bottom along the inclined plate (54) and then flows into the interior of the conveyor box (51). Step 2: When too much raw material is piled up on top of the guide plate (53), the weight of the raw material will increase after it is piled up, and the raw material will squeeze and drive the guide plate (53) to move to the bottom. The guide plate (53) moving to the bottom will drive the clamping plate (58) to move to the bottom. Step 3: When clamp 1 (58) moves to the bottom, it will cause the through rod (510) to rotate to the bottom. When the through rod (510) rotates to the bottom, it will cause the pivot (57) to rotate. When the through rod (510) rotates to the bottom, it will cause clamp 2 (59) to move to the top. When clamp 2 (59) moves to the top, it will cause the inclined plate (54) to rotate to the top. Step 4: After the inclined plate (54) rotates to the top, it will come into contact with the guide plate (53). After the inclined plate (54) comes into contact with the guide plate (53), the gap between the inclined plate (54) and the guide plate (53) is reduced, so that the raw material cannot continue to flow to the bottom through the originally set gap, so that when too much raw material is accumulated, it is impossible to continuously transport the raw material.
