Description

Technical Field

[0001] This invention relates to the technical field of hot air nonwoven fabric production, and in particular to an automated winding device for hot air nonwoven fabric production and its usage method. Background Technology

[0002] Hot-air nonwoven fabric is a nonwoven material made by bonding fibers together through hot air penetrating the fiber layers. It uses polymers such as polyester and polypropylene as main raw materials, and is manufactured through processes such as carding into a web, hot-air bonding, and cooling and setting. It features high bulkiness, good elasticity, strong warmth retention, and stable filtration efficiency, and is widely used in medical and health fields, filter materials, household goods, and agricultural coverings. In the production process of hot-air nonwoven fabric, the winding process is a crucial link connecting the front-end forming and the back-end processing. It requires winding the continuously produced nonwoven fabric into regular rolls for easy storage, transportation, and subsequent processing. High-quality winding equipment not only ensures uniform tension and a smooth surface of the nonwoven fabric rolls but also improves production efficiency. Therefore, the performance of the winding equipment plays a decisive role in the finished product quality and production efficiency of hot-air nonwoven fabric. Thus, there is a particular need for automated winding equipment for hot-air nonwoven fabric production and its usage method.

[0003] However, existing automated winding equipment for hot air nonwoven fabric production relies on manual or semi-automated operation to complete processes such as winding roller replacement, fabric tension adjustment, and cutting.

Summary of the Invention

[0004] The purpose of this invention is to provide an automated winding device for hot air nonwoven fabric production and its usage method, in order to solve the problems mentioned in the background art. The existing automated winding devices for hot air nonwoven fabric production rely on manual or semi-automatic operation to complete processes such as winding roller replacement, fabric tension adjustment and cutting.

[0010] Preferably, the flattening mechanism includes a third variable frequency motor, a bidirectional lead screw, a sliding block, a third connecting plate, a moving column, a limiting rod, a U-shaped plate, a spring, a fixing rod, and a pressure roller. The third variable frequency motor is mounted on the surface of the main body of the equipment. One end of the third variable frequency motor is connected to a bidirectional lead screw. One end of the bidirectional lead screw is connected to a sliding block. The surface of the sliding block is hinged to a third connecting plate. One end of the third connecting plate is hinged to a moving column. The surface of the moving column is connected to a limiting rod. One end of the limiting rod is connected to a U-shaped plate.

[0011] Preferably, one end of the bidirectional lead screw is in a movable relationship with the sliding block, and two sets of sliding blocks are provided.

[0012] Preferably, one end of the third variable frequency motor passes through the main body of the equipment and is connected to the bidirectional lead screw, and the third connecting plate is provided in two sets.

[0013] Preferably, the cutting mechanism includes a third cylinder, a fixed plate, a cutting plate, a knife groove, and a cutting knife. The third cylinder is mounted on the surface of the main body of the equipment, the fixed plate is connected to the surface of the main body of the equipment, one end of the third cylinder is connected to the cutting plate, the surface of the fixed plate is provided with a knife groove, and the surface of the cutting plate is connected to the cutting knife.

[0014] Preferably, one end of the cutting blade matches the size of the cutting groove, and the cutting blade and the cutting groove are horizontally aligned.

[0015] Preferably, it includes the following steps:

[0016] Step 1: Pass the hot air nonwoven fabric through the bottom of the guide roller and wrap it around the take-up roller. Set the program on the CNC table and start the fourth variable frequency motor to adjust the pressure of the guide roller on the hot air nonwoven fabric. After the fourth variable frequency motor is adjusted, the third variable frequency motor starts. The third variable frequency motor drives the sliding block to move through the bidirectional lead screw. The sliding block drives the moving column to move through the third connecting plate. The moving column then drives the U-shaped plate to move through the limit rod. When the U-shaped plate moves to a certain extent, the pressure roller on the surface of the U-shaped plate contacts and presses the hot air nonwoven fabric.

[0017] Step Two: After the hot air nonwoven fabric contacts and is pressed, the second variable frequency motor starts, driving the take-up roller to wind it. Under the smoothing and pressing of the pressure roller, the fabric continuously winds and expands. Once the hot air nonwoven fabric is wound to the appropriate size, one end of the third cylinder extends and moves the cutting board. When the cutting board reaches a certain position, the cutting blade on the surface of the cutting board cuts off one end of the hot air nonwoven fabric. At this time, one end of the second cylinder extends and drives the support block to contact the cut take-up roller. One end of the first electric push rod extends and drives the positioning block to disengage from the positioning groove. The second... One end of the electric push rod extends and drives the rotating rod to disengage from the groove. At this time, the support block supports the take-up roller, while one end of the second cylinder retracts according to the program. When one end of the second cylinder retracts to a certain extent, the first variable frequency motor starts and drives the take-up roller to move above the conveying device. One end of the first cylinder extends downward and drives the take-up roller to move downward until the take-up roller contacts the conveying device. When one end of the first cylinder continues to extend downward and the support block disengages from the take-up roller, the conveying device starts automatically and drives the wound take-up roller to convey it to the designated place.

[0018] Step 3: After the take-up roller is conveyed to the designated location, the first variable frequency motor rotates in the reverse direction, driving the support block to move to the position where the take-up roller is placed. One end of the first cylinder retracts, at which point the support block supports the take-up roller. Then, the first variable frequency motor starts and drives the take-up roller to the designated position. At this time, one end of the second cylinder extends and drives the take-up roller to the designated position. One end of the second variable frequency motor rotates slowly. When the signal emitted by the infrared transmitter inside the positioning block is accurately received by the infrared receiver inside the take-up roller, the second variable frequency motor stops, and one end of the first electric push rod and the second electric push rod retract. One end of the positioning block is embedded in the positioning groove, and one end of the rotating rod is embedded in the groove, thus completing the automatic replacement of the take-up roller.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. High degree of automation, significantly improving production efficiency: The equipment uses a CNC console with preset programs to precisely control the collaborative operation of multiple components, realizing full automation of the entire process from nonwoven fabric pre-tightening, winding, cutting to automatic replacement of winding rollers. Vision sensors monitor the status of winding rollers in real time and automatically trigger replacement actions, avoiding manual intervention. The transmission system can quickly complete the transfer of winding rollers. Compared with traditional manual or semi-automatic equipment, this device greatly reduces manpower input, shortens the production cycle, and effectively improves the continuity and production efficiency of nonwoven fabric winding.

[0021] 2. Multiple precise controls ensure winding quality. The guide rollers and variable frequency motor work together to adjust the tension of the nonwoven fabric. The pressure rollers continuously smooth the fabric during the winding process to ensure that the nonwoven fabric is flat and tight. The variable frequency motor precisely controls the speed and number of turns of the winding roller. Combined with the preset size triggering cutting mechanism, it realizes the standardized production of finished rolls. At the same time, the precise positioning structure, together with the locking function of the electric push rod, avoids the winding roller from deviating, effectively reducing problems such as fabric wrinkles and looseness, and improving the quality and consistency of finished products.

[0022] 3. Intelligent monitoring and stable structural design enhance equipment reliability. The equipment interacts with the CNC console through visual sensors to provide real-time feedback on the status of the take-up roller and automatically adjust the operating logic to prevent downtime due to material shortage. Cylinders and support blocks work together to provide stable support during the transfer of the take-up roller, reducing the risk of falling. In addition, the precise design of the transmission components, combined with the stable power output of each motor and cylinder, reduces mechanical wear, extends the service life of the equipment, and ensures the stability and reliability of the production process.

[0035] The self-rewinding mechanism 3 includes a first variable frequency motor 301, a first electric push rod 302, a second electric push rod 303, a threaded rod 304, a first connecting plate 305, a second connecting plate 306, a slider 307, a second variable frequency motor 308, a rotating rod 309, a first cylinder 310, a positioning block 311, a winding roller 312, a support plate 313, a first battery pack 314, an infrared transmitter 315, an infrared receiver 316, a second battery pack 317, a positioning groove 318, an insert 319, a vision sensor 320, a second cylinder 321, and a support block 322. The first variable frequency motor 301, the first electric push rod 302, and the second electric push rod 303 are all mounted on the surface of the main body 1. 03. One end of the first variable frequency motor 301 is connected to a threaded rod 304; one end of the first electric push rod 302 is connected to a first connecting plate 305; one end of the second electric push rod 303 is connected to a second connecting plate 306; one end of the threaded rod 304 is connected to a slider 307; a second variable frequency motor 308 is mounted on one side of the surface of the first connecting plate 305; a rotating rod 309 is connected to one side of the surface of the second connecting plate 306; a first cylinder 310 is mounted on the surface of the slider 307; one end of the second variable frequency motor 308 is connected to a positioning block 311; one end of the rotating rod 309 is connected to a take-up roller 312; one end of the first cylinder 310 is connected to a support plate 313; a first battery pack 314 is embedded in the surface of the positioning block 311; the positioning block... An infrared transmitter 315 is fitted at one end of the winding roller 311, an infrared receiver 316 is fitted on the surface of the winding roller 312, a second battery pack 317 is fitted on the surface of the winding roller 312, a positioning groove 318 is formed at one end of the winding roller 312, and an embedding groove 319 is formed at the other end of the winding roller 312. A vision sensor 320 is fitted on the surface of the support plate 313, and a second cylinder 321 is mounted on the surface of the support plate 313. One end of the second cylinder 321 is connected to a support block 322. The system is connected via a first variable frequency motor 301, a first electric push rod 302, a second electric push rod 303, a threaded rod 304, a first connecting plate 305, a second connecting plate 306, a slider 307, a second variable frequency motor 308, a rotating rod 309, a first cylinder 310, and a fixed... The components 311, 312, 313, 314, 315, 316, 317, 318, 319, 320, 321, 322, are arranged such that during operation, the CNC console 2 controls the coordinated operation of each component via a preset program. The hot-air nonwoven fabric first passes through the guide roller 10 and wraps around the take-up roller 312. The fourth variable frequency motor 8 drives the guide roller 10 to adjust the nonwoven fabric's pressure. Then, the flattening mechanism 5 presses and smooths the hot-air nonwoven fabric, completing the pre-tightening operation. Afterward, the second variable frequency motor 308 drives the take-up roller 312 to begin winding. When the fabric reaches the preset size, the cutting mechanism 4 cuts off one side of the hot-air nonwoven fabric.Subsequently, the piston rod of the second cylinder 321 extends, causing the support block 322 to contact the take-up roller 312 after winding and cutting. At the same time, the push rod of the first electric push rod 302 extends and causes the positioning block 311 to disengage from the positioning groove 318. The push rod of the second electric push rod 303 extends and causes the rotating rod 309 to disengage from the groove 319, thus separating the take-up roller 312 from the fixed structure. At this time, the support block 322 supports the take-up roller 312. Then, one end of the second cylinder 321 retracts according to the program. After the second cylinder 321 retracts to a certain extent, the first frequency conversion motor 301 starts, and its output shaft drives the threaded rod 304 to rotate. The threaded rod 304 and the slider 307 are connected by threads, which drives the rotation of the threaded rod 304. The motion is converted into linear motion of slider 307. Slider 307 drives the connected first cylinder 310, support plate 313, and other components, thereby moving the take-up roller 312 above the conveying device 7. Then, the piston rod of the first cylinder 310 extends downward and moves the take-up roller 312 downward until it contacts the conveying device 7. When the piston rod of the first cylinder 310 extends downward, causing the support block 322 to disengage from the take-up roller 312, the conveying device 7 automatically starts and transports the wound take-up roller 312 to the designated location. When the take-up roller 312 is replaced, the vision sensor 320 on the support plate 313 monitors the take-up roller 312 on the placement rack 6 in real time. If no empty take-up roller is detected, the sensor will detect the replacement. The vision sensor 320 transmits an electrical signal to the CNC table 2. At this time, the first variable frequency motor 301 continues to rotate according to the program, driving the threaded rod 304 to rotate, which in turn drives the slider 307 and the support block 322 to move until the vision sensor 320 detects that the take-up roller 312 is placed. The first variable frequency motor 301 stops. Then, the first variable frequency motor 301 rotates in the opposite direction, driving the threaded rod 304 to rotate in reverse, causing the support block 322 to move to the position where the take-up roller 312 is placed. The piston rod of the first cylinder 310 retracts. At this time, the support block 322 supports the take-up roller 312. Then, the first variable frequency motor 301 starts again, driving the threaded rod 304 to rotate, which drives the take-up roller 312 through the slider 307. The cylinder moves to the designated position. At this point, the piston rod of the second cylinder 321 extends and drives the take-up roller 312 to further adjust its position. The second variable frequency motor 308 slowly rotates the take-up roller 312. When the signal emitted by the infrared transmitter 315, powered by the first battery pack 314, inside the positioning block 311 is accurately received by the infrared receiver 316, powered by the second battery pack 317, inside the take-up roller 312, the second variable frequency motor 308 stops. The push rods of the first electric push rod 302 and the second electric push rod 303 retract at this time. One end of the positioning block 311 is inserted into the positioning groove 318, and one end of the rotating rod 309 is inserted into the groove 319, thus completing the automatic replacement of the take-up roller 312 and entering the next take-up cycle.

[0036] Furthermore, the vision sensor 320 is electrically connected to the CNC table 2, and one end of the rotating rod 309 matches the size of the groove 319. Through the setting of the vision sensor 320, during use, the vision sensor 320 is used to detect the presence or absence of the winding roller 312 on the placement rack 6 in real time, and feeds back the detection signal to the CNC table 2, providing a basis for the equipment to automatically replace the winding roller 312, and ensuring the continuous operation of the winding process.

[0037] Furthermore, one end of the positioning block 311 matches the size of the positioning groove 318, and two sets of support blocks 322 are provided. With the support blocks 322, during use, the support blocks 322 cooperate with the second cylinder 321 to support the winding roller 312 after it is cut, preventing the winding roller 312 from falling, and assisting in stabilizing the position of the winding roller 312 when it is moved.

[0038] Furthermore, one end of the threaded rod 304 is in a movable relationship with the slider 307. The second cylinder 321 is provided with two sets. Through the setting of the threaded rod 304, in use, the threaded rod 304 is connected to the output shaft of the first variable frequency motor 301, converting the rotational motion of the first variable frequency motor 301 into the linear motion of the slider 307, providing power and transmission path for the transfer of the take-up roller 312.

[0039] Furthermore, the flattening mechanism 5 includes a third variable frequency motor 501, a bidirectional lead screw 502, a sliding block 503, a third connecting plate 504, a moving column 505, a limiting rod 506, a U-shaped plate 507, a spring 508, a fixing rod 509, and a pressure roller 510. The third variable frequency motor 501 is mounted on the surface of the main body 1. One end of the third variable frequency motor 501 is connected to the bidirectional lead screw 502. One end of the bidirectional lead screw 502 is connected through the sliding block 503. The surface of the sliding block 503 is hinged to the third connecting plate 504. A movable column 505 is hinged to one end of plate 504. A limit rod 506 is connected through the surface of the movable column 505. A U-shaped plate 507 is connected to one end of the limit rod 506. A spring 508 is connected through the other end of the limit rod 506. A fixed rod 509 is connected to one side of the surface of the U-shaped plate 507. A pressure roller 510 is connected through the other end of the fixed rod 509. The system is connected via a third variable frequency motor 501, a bidirectional lead screw 502, a sliding block 503, a third connecting plate 504, a movable column 505, a limit rod 506, a U-shaped plate 507, and a spring 508. 08. The setting of the fixing rod 509 and the pressure roller 510: During use, the hot air nonwoven fabric first passes through the guide roller 10 and is wound around the take-up roller 312. After the fourth variable frequency motor 8 drives the guide roller 10 to adjust the nonwoven fabric pressure, the third variable frequency motor 501 starts first, and its output shaft drives the bidirectional lead screw 502 to rotate. Since the sliding block 503 is connected to the bidirectional lead screw 502 through a threaded connection, the rotation of the bidirectional lead screw 502 is converted into the linear movement of the sliding block 503 along the lead screw axis. The sliding block 503 is connected to the third connecting plate 504. The movable column 505 is fixedly connected, so the linear movement of the sliding block 503 drives the movable column 505 to move synchronously. The movable column 505 is also connected to the U-shaped plate 507 through the limiting rod 506. Under the guidance and support of the limiting rod 506, the movement of the movable column 505 eventually causes the U-shaped plate 507 to move until the pressure roller 510 on the fixed rod 509 on the surface of the U-shaped plate 507 contacts the hot air nonwoven fabric and presses it tightly, completing the pre-tightening operation. And due to the presence of the spring 508, the pressure roller 510 can always be in contact with the hot air nonwoven fabric.

[0040] Furthermore, one end of the bidirectional lead screw 502 is in a movable relationship with the sliding block 503. There are two sets of sliding blocks 503. When in use, the sliding block 503 is threadedly engaged with the bidirectional lead screw 502 and moves linearly when the bidirectional lead screw 502 rotates. It also drives the moving column 505 through the third connecting plate 504 to transmit motion and power.

[0041] Furthermore, one end of the third variable frequency motor 501 passes through the main body 1 and is connected to the bidirectional lead screw 502. The third connecting plate 504 is provided with two sets. Through the setting of the bidirectional lead screw 502, in use, the bidirectional lead screw 502 is connected to the output shaft of the third variable frequency motor 501, converting the rotational motion of the third variable frequency motor 501 into linear motion, driving the sliding block 503 to move along the lead screw axis, and providing a transmission basis for the displacement of the U-shaped plate 507.

[0042] Furthermore, the cutting mechanism 4 includes a third cylinder 401, a fixed plate 402, a cutting plate 403, a knife groove 404, and a cutting blade 405. The third cylinder 401 is mounted on the surface of the main body 1, and the fixed plate 402 is connected to the surface of the main body 1. One end of the third cylinder 401 is connected to the cutting plate 403. The surface of the fixed plate 402 has a knife groove 404, and the surface of the cutting plate 403 is connected to the cutting blade 405. Through the third cylinder 401 and the fixed plate 402, the cutting mechanism 401 can cut the cutting blade 405. 02. The setting of the cutting board 403, the knife groove 404 and the cutting knife 405 is as follows: When the hot air nonwoven fabric is wound to the preset size, one end of the third cylinder 401 automatically extends according to the setting, pushing the cutting board 403 to move. When the cutting board 403 moves to the fixed plate 402, the cutting knife 405 on the surface of the cutting board 403 cuts off one end of the hot air nonwoven fabric. The knife groove 404 opened on the surface of the fixed plate 402 can prevent the knife groove 404 from making hard contact with the fixed plate 402.

[0043] Furthermore, one end of the cutter 405 matches the size of the cutter groove 404, and the cutter 405 and the cutter groove 404 are horizontally aligned. With the setting of the cutter 405, during use, the cutter 405 is used to cut the hot air nonwoven fabric that has reached the predetermined winding size, so that the finished roll is separated from the nonwoven fabric to be processed.

[0044] Furthermore, this includes the following steps:

[0045] Step 1: Pass the hot air nonwoven fabric through the lower end of the guide roller 10 and wrap it around the take-up roller 312. The CNC table 2 is programmed and the fourth variable frequency motor 8 is automatically started to adjust the pressure of the guide roller 10 on the hot air nonwoven fabric. After the fourth variable frequency motor 8 is adjusted, the third variable frequency motor 501 is started. The start of the third variable frequency motor 501 drives the sliding block 503 to move through the bidirectional lead screw 502. The sliding block 503 drives the moving column 505 to move through the third connecting plate 504. The moving column 505 then drives the U-shaped plate 507 to move through the limit rod 506. When the U-shaped plate 507 moves to a certain extent, the pressure roller 510 on the surface of the U-shaped plate 507 contacts and presses the hot air nonwoven fabric.

[0046] Step Two: After the hot air nonwoven fabric is pressed and tightened, the second variable frequency motor 308 starts, driving the take-up roller 312 to wind it. Under the smoothing and pressing of the pressure roller 510, the winding continuously increases in size. When the hot air nonwoven fabric is wound to a suitable size, one end of the third cylinder 401 extends and drives the cutting plate 403 to move. When the cutting plate 403 moves to a certain position, the cutting blade 405 on the surface of the cutting plate 403 cuts off one end of the hot air nonwoven fabric. At this time, one end of the second cylinder 321 extends and drives the support block 322 to contact the wound-cut take-up roller 312. One end of the first electric push rod 302 extends and drives the positioning block 311 to disengage from the positioning groove 318. The second electric push rod... One end of 303 extends and drives the rotating rod 309 to disengage from the groove 319. At this time, the support block 322 supports the take-up roller 312, while one end of the second cylinder 321 retracts according to the program. When one end of the second cylinder 321 retracts to a certain extent, the first variable frequency motor 301 starts and drives the take-up roller 312 to move above the conveying device 7. One end of the first cylinder 310 extends downward and drives the take-up roller 312 to move downward until the take-up roller 312 contacts the conveying device 7. When one end of the first cylinder 310 extends downward and the support block 322 disengages from the take-up roller 312, the conveying device 7 starts automatically and drives the wound take-up roller 312 to be conveyed to the designated place.

[0047] Step 3: After the take-up roller 312 is delivered to the designated location, the first variable frequency motor 301 rotates in the reverse direction, driving the support block 322 to move to the position where the take-up roller 312 is placed. One end of the first cylinder 310 retracts, and at this time the support block 322 supports the take-up roller 312. Then the first variable frequency motor 301 starts and drives the take-up roller 312 to move to the designated position. At this time, one end of the second cylinder 321 extends and drives the take-up roller 312 to move to the designated position. One end of the second variable frequency motor 308 rotates slowly. When the signal emitted by the infrared transmitter 315 inside the positioning block 311 is accurately received by the infrared receiver 316 inside the take-up roller 312, the second variable frequency motor 308 stops, and one end of the first electric push rod 302 and the second electric push rod 303 retracts. One end of the positioning block 311 is embedded in the positioning groove 318, and one end of the rotating rod 309 is embedded in the groove 319, thereby completing the automatic replacement of the take-up roller 312.

[0048] Working Principle: An automated winding device for hot air nonwoven fabric production and its usage method. During operation, the CNC console 2 controls the coordinated operation of various components through a preset program. The hot air nonwoven fabric first passes through the guide roller 10 and is wound around the winding roller 312. The fourth variable frequency motor 8 drives the guide roller 10 to adjust the pressure. Then, the third variable frequency motor 501 drives the U-shaped plate 507 to move through transmission components such as the bidirectional lead screw 502 and the sliding block 503, so that the pressure roller 510 pre-tightens the nonwoven fabric. Subsequently, the second variable frequency motor 308 drives the winding roller 312 to wind the nonwoven fabric, and the pressure roller 510 simultaneously smooths it. When the preset size is reached, the third cylinder 401 in the cutting mechanism 4 pushes the cutting plate 403, and the cutting knife 405 completes the cutting. At this time, the second cylinder 321 drives the support block 322 to support the winding roller 312. At the same time, the first electric push rod 302 causes the positioning block 311 to disengage from the positioning groove 318, and the second electric push rod 303 causes the rotating rod 309 to disengage from the groove 319. Next, the first variable frequency motor 301 drives the take-up roller 312 to move above the conveying device 7 via the threaded rod 304 and the slider 307. The first cylinder 310 lowers it to contact the conveying device 7 and disengage from the support block 322. The take-up roller 312 is then conveyed to the designated position by the conveying device 7. When the take-up roller 312 is replaced, the vision sensor 320 on the support plate 313 detects the status of the take-up roller 312 on the placement rack 6. If there is no empty roller, the first variable frequency motor 301 is controlled to drive the support block 322 to move until a new roller is detected. Then, the support block 322 is rotated in the opposite direction to reset, supporting the new take-up roller 312 and moving it to the designated position. The position is adjusted by the second cylinder 321, and the second variable frequency motor 308 rotates at low speed. After precise positioning by the infrared transmitter 315 of the positioning block 311 and the infrared receiver 316 of the take-up roller 312, the first electric push rod 302 and the second electric push rod 303 are reset and fixed, completing the automatic replacement of the take-up roller 312 and entering the next cycle.
