Description

Technical Field

[0001] The present application relates to the technical field of refractory fiber paper processing, and in particular to a refractory fiber paper mixture forming and rolling system and a forming and rolling process. Background Art

[0002] Fiberboard is divided into fiberboard, fiber blanket and fiber paper according to its different properties and shapes. As for fiber paper, it is widely used in aerospace, industrial insulation, wallpaper and various non-woven products.

[0003] At present, the fiber paper forming process requires the following processes: stirring and dispersing the raw materials, slurry mixing, filtering and removing slag, suction filtration and forming, drying and conveying, and cutting and rolling, and finally the fire-resistant fiberboard is made.

[0004] In the prior art, Chinese patent No. CN216155082U discloses a winding device for processing and producing ceramic fiber paper, comprising a base, a winding mechanism provided on the top surface of the base, the winding mechanism comprising a side column fixed on one side of the top surface of the base, a transmission motor provided in the side column, a transmission shaft provided at the output end of the transmission motor, a driving gear provided at the other end of the transmission shaft opposite to the transmission motor, a winding roller provided outside the side column, one end of the winding roller passes through the side column and is meshed with the driving gear through a driven gear provided on the winding roller, a fastening mechanism is provided on the top surface of the base at the lower part of the winding roller, a traction mechanism is provided on the front part of the winding mechanism at the front part of the base, the cooperation of the traction mechanism and the fastening mechanism can prevent the ceramic fiber paper from being unevenly wound, and in addition, when the paper is wound, the semicircular telescopic support rod on the winding roller body is controlled to retract so that the paper can be easily separated from the roller body for easy removal, and the support of the fastening plate at the bottom will prevent the paper from falling and damaging.

[0005] In the above-mentioned prior art, the winding roller can wind up the refractory fiberboard, but the winding length cannot be determined and the length of the refractory fiberboard collected by the winding roller cannot be adjusted, so it has a certain degree of singleness.

[0006] Secondly, in the existing technology, when the refractory fiberboard is cut, a large amount of fine flying catkins will splash out from the cut area of ​​the refractory fiberboard. In a short period of time, it cannot produce a significant impact. However, as the device runs for a long time, the flying catkins will spread throughout the working area, causing the flying catkins to be inhaled by the workers operating the device, causing harm to the human body.

Detailed implementation manners

[0051] The following further describes the present application in detail with reference to the Figure 1-14 accompanying drawings.

[0052] The embodiment of the present application discloses a refractory fiber paper A mixing, forming and winding system and a forming and winding process. The present application can not only perform fixed-length cutting on the refractory fiber board, but also adjust the length of the fixed-length cutting of the refractory fiber board according to needs, improving the applicability and diversity of the device. Secondly, the present application can collect the flying flocs generated during cutting, preventing them from spreading in the working area and causing harm to the human body. Embodiment

[0053] Referring to Figure 1 and Figure 2 shown, a refractory fiber paper A mixing, forming and winding system includes a workbench 1, a conveying device 2, a discharging device 3 and a cutting device 4; the above structures are all existing and known devices.

[0054] A conveying device 2 is provided at the upper end of the workbench 1. The conveying device 2 includes a conveying roller and a driving component that drives the conveying roller to rotate. The refractory fiber paper A is conveyed from left to right through the conveying device 2. A number of conveying rollers are arranged at equal intervals on the workbench 1. The refractory fiber paper A coming out of the discharging device 3 is conveyed by the conveying rollers, so that the refractory fiber paper A can always move from left to right along the conveying device 2.

[0055] A discharging device 3 is provided on the left side of the upper end of the workbench 1, and a cutting device 4 for cutting the refractory fiber paper A at equal intervals is provided in the middle of the upper end of the workbench 1. The cutting device 4 includes a support frame 5 fixedly installed on the upper end of the workbench 1, and two limit rods 6 symmetrically distributed front and back slide through the inner side wall of the support frame 5. The function of the limit rod 6 is to limit the position of the cutting knife 7 to prevent the cutting knife 7 from tilting during the cutting process, resulting in uneven incisions.

[0056] The lower end of the limiting rod 6 is jointly installed with a cutting knife 7 for cutting the fiber paper. A cutting buffer groove 9 is opened at the upper end of the workbench 1 and directly below the cutting knife 7. The interior of the cutting buffer groove 9 is fixedly connected to a cutting buffer plate 10 through a buffer spring 8. The cutting buffer plate 10 is set in the cutting buffer groove 9 to slide up and down.

[0057] Look again Figure 2 As shown, it is a schematic diagram of the subject structure of the present invention. The side end of the cutting knife 7 is provided with a reciprocating cutting component 40 that drives itself to perform up and down reciprocating cutting. The cutting knife 7 is provided with a dust collection component 41 for collecting the fluff generated during the cutting process. The upper end of the workbench 1 and on the right side of the cutting device 4 is provided with a fixed length adjustment mechanism 42 for adjusting the cutting length of the refractory fiber paper A.

[0058] During the specific implementation process, the length of the refractory fiber paper A that needs to be cut at equal intervals is first adjusted through the fixed-length adjustment mechanism 42. After the length is adjusted, the refractory fiber paper A is automatically cut at equal intervals through the reciprocating cutting component 40, which can greatly improve the efficiency of mixing, forming and rolling the refractory fiber paper A. Then, the flying catkins generated by the cutting knife 7 during cutting are collected through the dust collection component 41.

[0059] See Figure 3 and Figure 4 As shown, when the discharging device 3 is drying the refractory fiber paper A, the device needs to be checked to ensure that the device is operating correctly. At the same time, it is necessary to determine the length of the refractory fiber paper A cut at equal intervals. Based on this, the present invention proposes a fixed-length adjustment mechanism 42 to achieve the change of the length of the refractory fiber paper A cut at equal intervals, as shown below:

[0060] The distance adjustment component 44 includes an L-shaped rod 440 that is slidably connected to the side end of the sawtooth block 426. An extrusion spring 441 is connected between the L-shaped rod 440 and the sawtooth block 426. The side of the L-shaped rod 440 away from the extrusion spring 441 is in the same plane as the I-shaped limit groove 424. The I-shaped limit groove 424 has equally spaced snap-fitting grooves that are snap-fitted with the L-shaped rod 440. A telescopic rod 442 that can be extended and retracted is fixed to the upper ends of two adjacent sawtooth blocks 426.

[0061] During the specific implementation process, the L-shaped rod 440 slides left and right, and in the initial state, the L-shaped rod 440 is inserted into the card slots opened at equal intervals in the I-shaped limit groove 424. When adjustment is required, the operator pushes the L-shaped rod 440 to pull the L-shaped rod 440 out of the card slots opened at equal intervals on the I-shaped limit groove 424, thereby driving the L-shaped rod 440 to separate from the card slot. At this time, the limit block 425 and the serrated block 426 can slide along the I-shaped limit groove 424. After the position of the serrated block 426 and the limit block 425 is adjusted, the L-shaped rod 440 is released, and the L-shaped rod 440 is reinserted into the card slot by the elastic force of the extrusion spring 441, fixing the limit block 425 and the serrated block 426 to prevent them from moving. At the same time, when one serrated block 426 is moved, several serrated blocks 426 are driven to move synchronously through the telescopic rod 442.

[0062] The size of the first gear 422 is fixed, and in the initial state, the shape formed by the plurality of sawtooth blocks 426 is the same size as the first gear 422. Therefore, when the sawtooth blocks 426 move outward, the diameter of the gear formed by the plurality of sawtooth blocks 426 is larger than the first gear 422. Therefore, the rotation rate of the synchronization plate 423 is slower than the rotation rate of the first gear 422, and vice versa.

[0063] Therefore, technical personnel are required to calibrate the device first. Taking 50 meters as an example, the cutting knife 7 cuts the refractory fiber paper A at equal intervals every 50 meters; when the device needs to change the length of the equal-interval cutting, so that the length of the equal-interval cutting of the refractory fiber paper A becomes longer, and it needs to be cut every 100 meters; according to the above steps, the position of the sawtooth block 426 is adjusted, and the moving position of the sawtooth block 426 is fixed according to a certain ratio. Then, in the process of moving the refractory fiber paper A, the speed at which the spring 451 rotates and tightens becomes slower, and the time when its torque reaches the maximum is twice as long as the time when the spring 451 is fully wound at 50 meters.

[0064] In simple terms, the time it takes for the spring to be tightened to the maximum torque is adjusted by changing the positions of several sawtooth blocks 426. The speed at which the conveying device 2 conveys the refractory fiber paper A is constant. The length of the refractory fiber paper A cut at equal intervals is adjusted by changing the time from the minimum torque to the maximum torque when the spring is tightened.

[0065] Look again Figure 3 and Figure 4 As shown, after the discharging device 3 produces the dried refractory fiber paper A, the conveying device 2 drives the refractory fiber paper A to rotate at a uniform speed, so the speed of the refractory fiber paper A moving from left to right is always the same until the moving end of the refractory fiber paper A rests against the left side wall of the cutting knife 7 on the buffer cutting board in the initial state. At this time, the position of the cutting knife 7 is the reference position of the refractory fiber board.

[0066] The fixed-length adjustment mechanism 42 includes two vertical plates 420 symmetrically distributed front and back fixedly installed on the upper end of the workbench 1. A drive motor 421 is provided on the vertical plate 420 located on the front side of the upper end of the workbench 1. The output end of the drive motor 421 is connected to the No. 1 gear 422 rotatably connected on the vertical plate 420 on the front side of the upper end of the workbench 1; the drive motor 421 controls the start and stop of the No. 1 gear 422.

[0067] A synchronization disk 423 rotating on the side wall of the vertical plate 420 is provided on the right side of the No. 1 gear 422, and a plurality of I-shaped limit grooves 424 are provided on the synchronization disk 423 at equal intervals. The I-shaped limit grooves 424 can limit the moving direction of the limit block 425, and can also prevent the limit block 425 from offset during the sliding process.

[0068] Look again Figure 3 and Figure 4 As shown, limit blocks 425 are slidably installed in several I-shaped limit grooves 424, and a serrated block 426 that cooperates with the number one gear 422 is fixed on the front side of several limit blocks 425. A synchronous belt 427 is engaged between the serrated block 426 and the number one gear 422, and the synchronous belt 427 drives the number one gear 422, the synchronous disk 423 and the tensioning gear 428 to rotate synchronously.

[0069] A tensioning spring rod 429 is fixed below the synchronous belt 427 and at the upper end of the workbench 1. The upper end of the tensioning spring rod 429 is rotatably connected to the tensioning gear 428 through a fixedly installed execution block 430. The tensioning gear 428 is engaged with the synchronous belt 427. A distance adjustment component 44 for adjusting the position of the limit block 425 is provided on the limit block 425. The tensioning spring rod 429 can ensure that when the distance adjustment component 44 is adjusted, the synchronous belt 427 is always in a straight state, thereby preventing the synchronous belt 427 from separating from the tensioning gear 428.

[0070] See Figure 5 As shown, when the second pulley 454 rotates counterclockwise, it drives the reciprocating gear 400 to rotate counterclockwise. During the counterclockwise rotation of the reciprocating gear 400, the reciprocating rack 401 is driven to move downward, and at the same time, the reciprocating rack 401 drives the cutting knife 7 to move downward to cut the refractory fiber paper A.

[0071] The reciprocating cutting assembly 40 includes a reciprocating gear 400 rotatably connected to the inner rear end of the support frame 5. The right side wall of the reciprocating gear 400 is engaged with a reciprocating rack 401 that slides up and down and passes through the support frame 5. The reciprocating gear 400 is always engaged with the reciprocating rack 401. The lower end of the reciprocating rack 401 is fixedly connected to the cutting knife 7. The rear side of the reciprocating gear 400 is provided with a linkage module 45 that drives the cutting knife 7 to move up and down.

[0072] During the specific implementation process, in the initial state, the cutting knife 7 rests on the cutting buffer plate 10. When the driving motor 421 rotates clockwise, the mainspring 451 rotates synchronously and in the same direction. At the same time, the mainspring 451 drives the reciprocating gear 400 to rotate clockwise through the No. 1 pulley 453, the No. 2 pulley 454 and the linkage belt 455. At this time, the cutting knife 7 starts to move upward through the reciprocating rack 401, and then the refractory fiber paper A loses the resistance of external force and starts to move from left to right along the conveying device 2.

[0073] Look again Figure 5 As shown, the linkage module 45 includes a protective shell 450 fixedly mounted on the vertical plate 420 at the rear upper end of the workbench 1, and the inner side wall of the protective shell 450 is fixedly connected to a spring 451, which is spirally arranged inside the protective shell 450, and the end of the spring 451 away from the protective shell 450 is fixedly connected to a driving rotating member 452; the driving rotating member 452 connects the synchronous disk 423 and the spring 451, so that when the synchronous disk 423 rotates, the spring 451 also rotates synchronously, and when the spring 451 rotates, one kind is wound around the driving rotating member 452, and the other is away from the driving rotating member 452.

[0074] The end of the driving rotating member 452 away from the protective shell 450 rotates and passes through the two vertical plates 420 and is fixedly connected to the synchronization disk 423. The end of the driving rotating member 452 close to the protective shell 450 is fixedly connected to the first pulley 453; the rear side wall of the support frame 5 is rotatably connected to the second pulley 454 at the same height as the first pulley 453, and the first pulley 453 and the second pulley 454 are jointly provided with a linkage belt 455, and the second pulley 454 is fixedly connected to the reciprocating gear 400; the driving rotating member 452 is provided with a control module 46 for controlling its disconnection and connection; the linkage belt 455 can drive the number one pulley 453 and the number two pulley 454 to rotate synchronously.

[0075] During the specific implementation process, when the refractory fiberboard is against the left side of the cutting knife 7, the driving motor 421 is started, and the driving motor 421 drives the No. 1 gear 422 to rotate clockwise, and the No. 1 gear 422 drives the synchronous disk 423 to rotate clockwise through the synchronous belt 427. When the synchronous disk 423 rotates clockwise, it drives the mainspring 451 to start tightening through the driving rotating member 452, and the mainspring 451 gradually approaches the driving rotating member 452 and generates a certain elastic force.

[0076] When the mainspring 451 is fully wound, the driving rotating member 452 is disconnected by the control module 46, so that the mainspring 451 starts to rotate counterclockwise due to its own elastic force. During the counterclockwise rotation of the mainspring 451, the mainspring 451 drives the first pulley 453, the second pulley 454 and the linkage belt 455 to rotate counterclockwise through the driving rotating member 452.

[0077] See Figure 6 、 Figure 7 and Figure 8 As shown, it is a structural diagram for controlling the disconnection and connection of the driving rotating member 452. The control module 46 includes a winding roller 460 fixedly connected to the driving rotating member 452 between the protective shell 450 and the vertical plate 420. A non-elastic rope 461 is wound on the winding roller 460. One end of the rope 461 is fixedly connected to the protective shell 450, and the other end of the rope 461 slides through the driving rotating member 452. The rope 461 starts the connecting role. When the driving member rotates, the rope 461 is wound on the winding roller 460, so that the rope 461 can pull the square connecting block 466 to move.

[0078] The driving rotating member 452 is a hollow structure, and the driving rotating member 452 includes two identical control rotating shafts 462. The opposite sides of the two control rotating shafts 462 are fixedly connected to the protective shell 450 and the synchronization disk 423 respectively. The opposite sides of the two control rotating shafts 462 are respectively provided with an annular groove 463 and an annular column 464 slidably arranged in the annular groove 463; the annular column 464 and the annular groove 463 conflict with each other. When the two control rotating shafts 462 are disconnected, the two control rotating shafts 462 are pressed against each other through the annular column 464 and the annular groove 463, but the two control rotating shafts 462 are in a disconnected state.

[0079] A square groove 465 is provided at the center of the opposite sides of the two control rotating shafts 462, and a square connecting block 466 is slidably installed in the square groove 465 on the side close to the protective shell 450; when the square connecting block 466 moves into the square groove 465 on the two control rotating shafts 462, the two control rotating shafts 462 rotate synchronously, and when the square connecting block 466 is located in the square groove 465 close to the protective shell 450, the two control rotating shafts 462 are disconnected and separated.

[0080] The side of the square connecting block 466 close to the protective shell 450 is fixedly connected to the twisted rope 461 through a fixing column 467 , and a snap-fit ​​assembly 47 is provided on the square connecting block 466 .

[0081] During the specific implementation process, in the initial state, in order to ensure that when the drive motor 421 rotates clockwise, the mainspring 451 can rotate clockwise synchronously, the square connecting block 466 is located between the square slots 465 on the two control rotating shafts 462. At this time, the two control rotating shafts 462 are connected through the square connecting block 466.

[0082] When the driving motor 421 rotates clockwise, the rope 461 begins to be wound around the winding roller 460 on the control rotating shaft 462 at a uniform speed, so that the end of the rope 461 away from the protective shell 450 gradually shortens. At the same time, the rope 461 drives the square connecting block 466 along the inner wall of the control rotating shaft 462 toward the protective shell 450, until the moment the spring 451 is fully wound, the square connecting block 466 just enters the interior of the control rotating shaft 462 close to the protective shell 450. At this time, the two control rotating shafts 462 are separated, and the torque of the spring 451 after being fully wound reaches the maximum. At this time, the spring 451 needs to rotate counterclockwise.

[0083] When the mainspring 451 rotates counterclockwise and the torque disappears, the mainspring 451 becomes loose. At this time, the square connecting block 466 is driven by the clamping assembly 47 to re-enter between the two square slots 465, so that the two control rotating shafts 462 are connected to each other.

[0084] Replay Figure 6 and Figure 7 As shown, the snap-fit ​​assembly 47 includes a push-pull plate 471 slidably connected to the upper end of the fixed column 467, and an auxiliary spring 472 is connected between the push-pull plate 471 and the inner wall of the control rotating shaft 462, and the push-pull plate 471 is slidably set on the inner side wall of the control rotating shaft 462 close to the protective shell 450; the push-pull plate 471 and the control rotating shaft 462 close to the protective shell 450 form an air pump-like suction device, and when the square connecting block 466 moves toward the direction of the protective shell 450, the push-pull plate 471 transports the air between the remaining control rotating shafts 462 to the snap-fit ​​airbag 473, causing the snap-fit ​​airbag 473 to bulge.

[0085] The auxiliary spring 472 is used to ensure that when the mainspring 451 is relaxed, the square connecting block 466 is pushed between the two square slots 465 by the elastic force of the auxiliary spring 472 , so that the two control rotating shafts 462 are connected.

[0086] A snap-fit ​​airbag 473 is fixedly connected to the control rotating shaft 462 near the protective shell 450. One side of the snap-fit ​​airbag 473 is connected to the inner wall of the control rotating shaft 462 near the protective shell 450 through an air tube, and the other side of the snap-fit ​​airbag 473 is in contact with a snap-fit ​​block 474. The snap-fit ​​block 474 is set in the control rotating shaft 462 for sliding left and right. When the snap-fit ​​airbag 473 swells, the snap-fit ​​airbag 473 begins to squeeze the snap-fit ​​block 474, so that the snap-fit ​​block 474 can be inserted into the snap-fit ​​groove 476 on the square connecting block 466, thereby fixing the position of the square connecting block 466.

[0087] The outer side of the snap-in airbag 473 is connected to a No. 1 one-way air outlet valve 475 for uniform air outlet; a snap-in groove 476 that is plugged into the snap-in block 474 is provided on one side of the square connecting block 466 corresponding to the snap-in block 474, and a No. 2 one-way air outlet valve 477 is provided on the push-pull plate 471.

[0088] The function of the No. 1 one-way air outlet valve 475 is to deflate air at a uniform speed. When a large amount of gas is filled inside the snap-fit ​​airbag 473, the snap-fit ​​block 474 is inserted into the snap-fit ​​groove 476 on the square connecting block 466, and the No. 1 one-way air outlet valve 475 begins to deflate. However, it should be noted that the deflation speed of the No. 1 one-way air outlet valve 475 is relatively low, and the air is always deflated. After the gas in the snap-fit ​​airbag 473 has leaked out, the snap-fit ​​block 474 is separated from the snap-fit ​​groove 476. At this time, the square connecting block 466 moves back between the two square grooves 465, so that the two control rotating shafts 462 are reconnected from the separated state.

[0089] Example 2: Based on Example 1, in order to further improve the efficiency of the cutting process of the refractory fiber paper A, the present invention also provides a dust suction component 41, which is used to absorb the flying catkins generated when the cutting knife 7 cuts the refractory fiber paper A, thereby preventing the flying catkins accumulated during the long-term operation of the device from being absorbed by the human body.

[0090] See Figure 9 As shown, the dust collection assembly 41 includes a dust collection cover 410 fixedly mounted on the cutting knife 7, and a dust collection airbag 411 is provided inside the dust collection cover 410. It should be noted that the length of the cutting knife 7 is longer than the length of the dust collection cover 410, and its function is to facilitate the cutting knife 7 to be inserted into the cutting buffer groove 9.

[0091] The lower end of the dust suction airbag 411 is in contact with the No. 1 pressing plate 412, and the No. 1 pressing plate 412 is slidably distributed on the inner wall of the dust suction hood 410; the No. 1 safety plate can compress the dust suction airbag 411, and the lower end of the dust suction hood 410 is provided with two circular holes symmetrically distributed on the left and right, and a telescopic extrusion spring rod 413 is fixedly installed in the circular hole, and a synchronously telescopic telescopic hood 414 is provided on the outside of the telescopic extrusion spring rod 413.

[0092] It should be noted that the dust suction airbag 411 is an elastic airbag. After being compressed, it can automatically adsorb external air during the restoration process. After the dust suction airbag 411 is compressed, it can automatically return to its original state.

[0093] Refer to Figure 10 and Figure 11 As shown in

[0094] and

[0095] An auxiliary groove communicating with the cutting buffer groove 9 is opened at the upper end of the workbench 1 and directly below the telescopic cover 414. A U-shaped plate 415 for closing the auxiliary groove is fixedly installed in the auxiliary groove to slide left and right; the telescopic extrusion spring rod 413 cooperates with the U-shaped plate 415; in the initial state, the U-shaped plate 415 seals the auxiliary groove. At this time, during the downward movement of the cutting knife 7, the telescopic extrusion spring rod 413 abuts against the upper end of the U-shaped plate 415 and gradually compresses and deforms. At this time, the U-shaped plate 415 is always on the auxiliary groove.

[0096] An execution spring 416 is connected between one end of the U-shaped plate 415 away from the cutting buffer groove 9 and the workbench 1. Two symmetrically distributed triangular blocks 417 are fixedly connected to the lower end of the cutting buffer plate 10; when the cutting knife 7 presses down and applies a downward pressure to the cutting buffer plate 10, the cutting buffer plate 10 enters the cutting buffer groove 9. At this time, the dust suction cover 410 abuts against the upper end of the refractory fiber paper A. The triangular blocks 417 fixed to the lower end of the cutting buffer plate 10 squeeze the U-shaped plate 415, causing the U-shaped plate 415 to move away from the cutting buffer groove 9 until the auxiliary groove is opened. At this time, the telescopic extrusion spring rod 413 loses the support force of the U-shaped plate 415, and the telescopic extrusion spring rod 413 extends into the auxiliary groove.

[0097] Refer to Figure 12 and Figure 13As shown, after the flying catkins are absorbed into the dust collecting airbag 411, if they are not removed in time, when the refractory fiber paper A is subsequently cut, the flying catkins sucked into the knife dust collecting airbag 411 will be squeezed out by the first pressing plate 412, and the effect of collecting the flying catkins cannot be achieved. Based on this, the present invention proposes a collecting component 48, as shown below:

[0098] The collecting component 48 includes a dust collecting frame 480 that is movably connected to the left and right ends of the dust hood 410, and the dust collecting frame 480 is connected to one side of the three-way dust collection tube 419; the dust collecting frame 480 can be disassembled. After the flying catkins in the dust collection airbag 411 enters the dust collecting frame 480 through the three-way dust collection tube 419, the dust collecting frame 480 can be taken out, processed, and then replaced with a new dust collecting frame 480.

[0099] The three-way dust suction pipe 419 is a pipe with three holes, one end of which is connected to the dust suction air bag 411, one end is connected to the dust suction port 418, and one end is connected to the dust collection frame 480.

[0100] A cylindrical block 481 that blocks the diameter of the dust suction tube 419 slides at the intersection of the three-way dust suction tube 419, and the end of the cylindrical block 481 close to the dust collecting frame 480 is connected to the inner wall of the dust suction tube 419 with a collecting spring 482, and the end of the cylindrical block 481 close to the dust collecting frame 480 is connected to a non-elastic traction rope 483, which slides through the dust suction cover 410 and is fixedly connected to the inner upper end of the support frame 5, and a reversing roller is provided in the middle of the traction rope 483 to prevent it from wearing during the sliding process; the traction rope 483 can pull the cylindrical block 481 to move.

[0101] A second pressing plate 484 is slidably installed on the upper end of the interior of the dust hood 410, and an execution column 485 is fixedly installed on the upper end of the second pressing plate 484. The execution column 485 slides through the dust hood 410, and the lower end of the second pressing plate 484 is in contact with the dust bag 411.

[0102] During the specific implementation process, in the initial state, the cylindrical block 481 is always located at one end of the dust suction tube 419 close to the dust suction port 418 through the elastic force of the collecting spring 482. When the dust suction hood 410 moves downward following the cutting knife 7, the traction rope 483 begins to tighten, and then the traction rope 483 pulls the cylindrical block 481 toward one end of the dust suction tube 419 close to the dust collecting frame 480. At this time, the dust suction air bag 411 in the three-way dust suction tube 419 is connected to the dust suction port 418, and then the dust suction air bag 411 is squeezed, and then the dust suction air bag 411 inhales the air containing flying catkins during cutting.

[0103] After the air containing flying catkins enters the dust suction bag 411, the dust suction hood 410 needs to move upward. At this time, the straightened traction rope 483 begins to relax, and the stretched collection spring 482 re-enters the dust suction tube 419 near the end of the dust suction port 418 through its elastic force. At this time, the dust suction bag 411 is connected to the dust collection frame 480, and then the dust suction hood 410 and the cutting knife 7 continue to move upward. During the upward movement, the execution column 485 hits the inner wall of the knife support frame 5, and then the execution column 485 drives the No. 2 extrusion plate to squeeze the dust suction bag 411 from top to bottom, so that the dust suction bag 411 is compressed, and the flying catkins in the dust suction bag 411 enter the dust collection frame 480, and then the dust collection frame 480 collects and fixes the flying catkins to prevent the flying catkins from re-entering the dust suction bag 411. Finally, the above operation is repeated to achieve equal-spaced cutting of the refractory fiber paper A.

[0104] In addition, the present invention also includes a refractory fiber paper A mixed material forming and rolling process, and the rolling process is as follows:

[0105] S1. Preparation: After the raw materials for preparing the refractory fiber paper A are crushed, stirred and dispersed, they are evenly mixed, necessary auxiliary agents are added during the mixing process, and they are fully stirred. Then, after filtering and removing the residue, they are shaped. After the shaping is completed, they are dried and conveyed through the discharging device 3. The refractory fiber paper A coming out of the discharging device 3 is in the form of long strips and is conveyed by the conveying device 2.

[0106] S2. Fixed-length cutting: The speed at which the mainspring 451 is tightened is adjusted by adjusting the positions of the serrated blocks 426, thereby achieving cutting of the refractory fiber paper A to different lengths. The serrated blocks 426 move away from the center of the synchronization disk 423, and the diameter of the gear formed by the serrated blocks 426 is larger than the diameter of the first gear 422. At this time, the longer the mainspring 451 is tightened to the maximum torque, the longer the length of the refractory fiber paper A cut at equal intervals will be.

[0107] S3. Product cutting: After the spring 451 inside the protective shell 450 is tightened to the maximum limit force, the spring 451 starts to rotate in the reverse direction. During the reverse rotation, the spring 451 controls the cutting knife 7 to move up and down and cuts the refractory fiber paper A. Then the cutting knife 7 is lifted and the refractory fiber paper A continues to be transported, thereby repeating the above steps to cut the refractory fiber paper A back and forth with equal intervals.

[0108] S4. Collection of fluff: When the cutting knife 7 cuts the refractory fiber paper A, the air around the cutting knife 7 and the flying fluff generated in the air by the cutting knife 7 are absorbed by the dust suction airbag 411. Then, the fluff in the dust suction airbag 411 is passed into the detachable dust collection frame 480 through the three-way dust suction pipe 419 to prevent the fluff from spreading in the air. Finally, the cut refractory fiber paper is rolled up.

[0109] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.

Preparation: After the raw materials for preparing the refractory fiber paper are crushed, stirred and dispersed, they are uniformly mixed, necessary auxiliary agents are added during the mixing process, and the mixture is fully stirred. Then, after filtering and removing the residue, the raw materials are shaped. After the shaping is completed, the raw materials are dried and conveyed through the discharging device (3). The refractory fiber paper coming out of the discharging device (3) is in the form of long strips and is conveyed through the conveying device (2); S2, fixed-length cutting: adjusting the speed at which the spring (451) is wound up by the fixed-length adjustment mechanism (42), thereby achieving cutting of the refractory fiber paper into different lengths; S3, product cutting: after the spring (451) inside the protective shell (450) is tightened to the maximum limit force, the spring (451) starts to rotate in the reverse direction, and the spring (451) controls the cutting knife (7) to move up and down during the reverse rotation, and cuts the refractory fiber paper, and then the cutting knife (7) is lifted, and the refractory fiber paper continues to be transported, thereby repeatedly cutting the refractory fiber paper back and forth with equal spacing; S4. Collection of fluff: When the cutting knife (7) cuts the refractory fiber paper, the air around the cutting knife (7) and the flying fluff generated in the air by the cutting knife (7) are absorbed by the dust collection bag (411), and then the fluff in the dust collection bag (411) is passed into the detachable dust collection frame (480) through the three-way dust collection pipe (419) to prevent the fluff from spreading in the air. Finally, the cut refractory fiber paper is rolled.
