Description

Technical Field

[0001] This invention belongs to the field of nonwoven fabric technology, specifically a production method and intelligent production equipment for industrial nonwoven fabrics. Background Technology

[0002] Industrial nonwoven fabrics are a new type of textile material. They are not produced using traditional textile processes, but rather through a series of processing techniques on fibers, short fibers, or textiles. Industrial nonwoven fabrics come in many types and applications, offering excellent breathability, sound insulation, water resistance, and dustproofing, while also possessing good strength and abrasion resistance.

[0003] In the production process of industrial nonwoven fabrics, the nonwoven fabrics need to be slit and rewound to achieve the required width. However, when slitting nonwoven fabrics, it is usually necessary to fix the unslit rolls of nonwoven fabrics onto rotating shafts, release them for slitting, and then rewound the slit nonwoven fabrics onto multiple rotating shafts. The feeding of unslit nonwoven fabric rolls and the unloading of slit and rewound nonwoven fabric rolls usually require manual operation, resulting in a low degree of automation in the entire process. Furthermore, lifting the unslit nonwoven fabric rolls usually requires a significant amount of manpower and resources.

[0004] In view of this, the present invention provides a method for producing industrial nonwoven fabrics and intelligent production equipment to solve the above-mentioned technical problems. Summary of the Invention

[0007] In this application, the slitting and rewinding machine is the existing slitting and rewinding machine, which can slit and rewind nonwoven fabric; the unslit nonwoven fabric roll is fixed on the fixed shaft, and the slit and rewound nonwoven fabric roll is also fixed on the fixed shaft, that is, both the unslit nonwoven fabric roll and the slit and rewound nonwoven fabric roll are equipped with auxiliary roll changing units.

[0008] Preferably, the auxiliary roll-changing unit includes: a first block; the first block is fixedly connected to the slitting and rewinding machine, and a first motor is fixedly connected to the side of the first block; a second block, the second block is fixedly connected to the slitting and rewinding machine, a fixed shaft is slidably connected inside the second block, and several support blocks are evenly arranged around the fixed shaft; the support blocks can extend and retract into the fixed shaft; the first motor can drive the fixed shaft to rotate; a drive wheel, a drive wheel is provided inside the second block, and contact blocks are slidably connected around the drive wheel, the contact blocks contact the fixed shaft, and the rotation of the drive wheel drives the fixed shaft to slide relative to the second block; a connecting cylinder is fixedly connected below the drive wheel; a control block, a control block is fixedly connected below the second block, a second motor is provided inside the control block, the connecting cylinder extends into the control block, and the second motor can drive the connecting cylinder to rotate; and a lifting platform, a lifting platform is fixedly provided below one of the auxiliary roll-changing units, the lifting platform is used to lift the unslit nonwoven fabric roll, and an inclined plate is fixedly connected to the lifting platform.

[0009] Preferably, the drive wheel has several circumferentially oriented cavities, each cavity having a slidably connected contact block. A spring is fixedly connected between the contact block and the end of the cavity. An annular electromagnet is provided at the top of the connecting cylinder. A piston block is slidably connected inside the connecting cylinder. A spring is fixedly connected between the bottom of the piston block and the bottom of the connecting cylinder. The drive wheel is hollow, and the interior of the connecting cylinder, the drive wheel, and each cavity are interconnected.

[0010] Preferably, an elastic block is fixedly connected to the end of the contact block away from the interior of the drive wheel.

[0011] Preferably, a plurality of support blocks are slidably connected around the fixed shaft, and a plurality of abutment blocks are fixedly connected to one side of each support block inside the fixed shaft; a pull rod is slidably connected inside the fixed shaft, one end of the pull rod protruding from the fixed shaft and its cross-section being increased to be the same size as the cross-section of the fixed shaft; a plurality of receiving grooves are provided around the pull rod corresponding to the position of each abutment block; a second cavity is provided inside the fixed shaft, and a protrusion is provided on the pull rod, the protrusion of the pull rod being located inside the second cavity.

[0012] Preferably, the abutment is made of a permanent magnet.

[0013] Preferably, the fixed shaft is provided with a meshing tooth at one end near the first block, the first block is hollow inside, a meshing block is provided inside the first block, the end of the meshing block is provided with a meshing tooth, the meshing block is slidably connected to the output shaft of the first motor, and a third spring is fixedly connected between the end of the meshing block near the first motor and the inner wall of the first block.

[0014] The fixed shaft passes through block number two and can slide relative to it. Block number one has a hole on its side facing block number two, through which the fixed shaft can pass. Initially, blocks number one and two jointly support the fixed shaft, meaning the fixed shaft is located between blocks number one and two. The support block supports the roll of non-woven fabric being wound. When the support block extends, it contacts and presses against the inner wall of the roll, causing the roll to rotate along with the fixed shaft. When the support block retracts, the fixed shaft can be pulled out of the roll. When the contact block retracts to the drive wheel, it does not contact the fixed shaft and does not affect its rotation. The fixed shaft rotates, and when the contact block extends and contacts the fixed shaft, it coordinates with the drive wheel to rotate, causing the fixed shaft to slide relative to the second block. A hydraulic rod can be installed inside the lifting platform, with the top of the lifting platform fixed to the top of the hydraulic rod. When the hydraulic rod extends, it raises the top of the lifting platform, thereby raising the non-woven fabric roll above the top of the lifting platform. The inclined plate facilitates transporting the non-woven fabric roll to the top of the lifting platform. When the first spring is in its original position, the contact block retracts into the first cavity. The first piston block is made of a material that can be attracted by a magnet, such as iron. When the annular electromagnet is energized, it attracts... As piston block number one approaches, spring number two extends; the interior of the connecting cylinder, the drive wheel, and each chamber number one can be filled with hydraulic oil. When piston block number one is attracted and displaced to its maximum extent by the annular electromagnet, the contact block will not detach from chamber number one; the elastic block can be made of rubber to increase friction; the support block will not detach from the fixed shaft, and when the abutment is in the receiving groove, the support block is in a retracted state; chamber number two, in conjunction with the protrusion on the pull rod, acts as a limit, preventing the pull rod from detaching from the fixed shaft, and when the pull rod is pulled to its limit position, the abutment is precisely located in the receiving groove. The abutment is made of a permanent magnet, and the pull rod is made of a material that can be attracted by a magnet, such as iron. This ensures that the abutment is always in close contact with the pull rod, meaning that the support block can retract when the abutment is in the receiving groove. When the meshing teeth on the meshing block engage with the meshing teeth on the fixed shaft, the meshing block can drive the fixed shaft to rotate. At this time, the third spring is in a compressed state, and the meshing block is slidably connected to the output shaft of the first motor. They can only slide relative to each other and cannot rotate relative to each other. A keyway connection can be used. The meshing block and the third spring ensure that the meshing teeth of the fixed shaft and the meshing teeth of the meshing block can mesh smoothly.

[0015] Preferably, the slitting and rewinding machine is fixedly provided with a plurality of receiving trays, each of which is located below each slitting nonwoven fabric roll.

[0016] The receiving tray is located below the fixed shaft of the rewinding nonwoven fabric. When unloading is required, the fixed shaft is pulled out, and the receiving tray can catch the cut nonwoven fabric roll, which can be taken out by the staff for easy operation.

[0017] A method for producing industrial nonwoven fabric, the method employing an intelligent production equipment for industrial nonwoven fabric as described in any one of the above, comprising the following steps:

[0018] S1: When feeding uncut nonwoven fabric rolls, the annular electromagnet is energized to attract piston block No. 1 closer, causing the contact block to extend. Then, motor No. 2 is started, first pulling the pull rod to align the receiving groove with the abutment block, the support block retracts, and then the fixed shaft slides, causing the fixed shaft to be pulled away from between blocks No. 1 and No. 2. Then, the worker transports the uncut nonwoven fabric roll to the top of the lifting platform. The lifting platform raises the nonwoven fabric roll so that the hole of the nonwoven fabric roll is aligned with the fixed shaft. Motor No. 2 reverses, and the fixed shaft passes through the hole of the uncut nonwoven fabric roll, causing the meshing teeth of the fixed shaft to mesh with the meshing teeth of the meshing block. Then, the pull rod moves into the fixed shaft, causing the abutment block to disengage from the receiving groove, the support block extends, and contacts the nonwoven fabric roll to fix it.

[0019] S2: Then the lifting platform descends, and the slitting and rewinding machine slits the non-woven fabric. The slit non-woven fabric is then rewound onto another fixed shaft. During this process, motor number one starts, driving each fixed shaft to rotate accordingly, providing power for the release or rewinding of the non-woven fabric roll.

[0020] S3: When the slit and rewound nonwoven fabric roll needs to be unloaded from the fixed shaft, the control support block retracts, the fixed shaft is pulled out, and the slit nonwoven fabric roll can be removed.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The present invention discloses a method for producing industrial nonwoven fabric and an intelligent production equipment thereof, which includes a plurality of auxiliary roll-changing units on a slitting and rewinding machine. Each auxiliary roll-changing unit includes a fixed shaft, and both the unslit nonwoven fabric roll and the slit nonwoven fabric roll are fixed by the fixed shaft.

Then, a second motor is started, first pulling the pull rod to align the receiving groove with the abutment block, causing the support block to retract, and then driving the fixed shaft to slide, causing the fixed shaft to be pulled away from between blocks No. 1 and No. 2. Subsequently, the worker transports the uncut roll of nonwoven fabric to the top of the lifting platform, the lifting platform raises the nonwoven fabric roll, so that the hole of the nonwoven fabric roll is aligned with the fixed shaft, the second motor reverses, the fixed shaft passes through the hole of the uncut nonwoven fabric roll, and the meshing teeth of the fixed shaft mesh with the meshing teeth of the meshing block, and then the pull rod moves into the fixed shaft, causing the abutment block to disengage from the receiving groove, the support block to extend, and contact the nonwoven fabric roll to fix it.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown;

[0038] The present invention discloses an intelligent production equipment for industrial nonwoven fabric, comprising: a slitting and rewinding machine 1, which is capable of slitting and rewinding nonwoven fabric; and auxiliary roll changing units 2, wherein the slitting and rewinding machine 1 is provided with a plurality of auxiliary roll changing units 2, each auxiliary roll changing unit 2 including a fixed shaft 21, wherein both the unslit nonwoven fabric roll and the slit nonwoven fabric roll are fixed by the fixed shaft 21, and the auxiliary roll changing units 2 are capable of releasing the unslit nonwoven fabric, rewinding the slit nonwoven fabric, and assisting in feeding the unslit nonwoven fabric roll and unloading the slit nonwoven fabric roll.

[0039] In the production of industrial nonwoven fabrics, the fabric needs to be slit and rewound to achieve the required width. However, during slitting, the unslit roll is usually fixed to a rotating shaft, released for slitting, and then rewound onto multiple rotating shafts. Both loading the unslit roll and unloading the slit and rewound rolls typically require manual operation, resulting in a low degree of automation. Furthermore, lifting the unslit roll usually requires manual intervention. It requires a high level of manpower and material resources; therefore, several auxiliary roll-changing units 2 are set on the slitting and rewinding machine 1. The auxiliary roll-changing unit 2 includes a fixed shaft 21. Both the unslit nonwoven fabric roll and the slit nonwoven fabric roll are fixed by the fixed shaft 21. The auxiliary roll-changing unit 2 can release the unslit nonwoven fabric and rewind the slit nonwoven fabric. It can also assist in feeding the unslit nonwoven fabric roll and assist in unloading the slit nonwoven fabric roll, reducing manual operation, improving the automation level of feeding and unloading, and reducing the consumption of manpower and material resources.

[0040] In this application, the slitting and rewinding machine 1 is the same as the prior art slitting and rewinding machine 1, which can slit and rewind nonwoven fabric; the unslit nonwoven fabric roll is fixed on the fixed shaft 21, and the slit and rewound nonwoven fabric roll is also fixed on the fixed shaft 21, that is, both the unslit nonwoven fabric roll and the slit and rewound nonwoven fabric roll are provided with auxiliary roll changing unit 2.

[0041] As one specific embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown; the auxiliary winding unit 2 includes: a first block 22; the first block 22 is fixedly connected to the slitting and rewinding machine 1, and a first motor 221 is fixedly connected to the side of the first block 22; a second block 23, the second block 23 is fixedly connected to the slitting and rewinding machine 1, a fixed shaft 21 is slidably connected inside the second block 23, and several support blocks 24 are evenly arranged around the fixed shaft 21; the support blocks 24 can extend and retract into the fixed shaft 21; the first motor 221 can drive the fixed shaft 21 to rotate; a drive wheel 25, the second block 23 is provided with a drive wheel 25, and contact blocks 26 are slidably connected around the drive wheel 25. 6. The fixed shaft 21 is driven to slide relative to the second block 23 by the rotation of the drive wheel 25; a connecting cylinder 27 is fixedly connected below the drive wheel 25; a control block 28 is fixedly connected below the second block 23, and a second motor 281 is installed inside the control block 28. The connecting cylinder 27 extends into the control block 28, and the second motor 281 can drive the connecting cylinder 27 to rotate; a lifting platform 29 is fixedly installed below one of the auxiliary roll changing units 2. The lifting platform 29 is used to lift the uncut nonwoven fabric roll, and an inclined plate 291 is fixedly connected to the lifting platform 29;

[0042] like Figure 8 , Figure 9 , Figure 10 As shown; the drive wheel 25 has several first cavities 3 circumferentially opened inside, and a contact block 26 is slidably connected inside each first cavity 3. A first spring 31 is fixed between the contact block 26 and the end of the first cavity 3. An annular electromagnet 32 ​​is provided at the top of the connecting cylinder 27. A first piston block 33 is slidably connected inside the connecting cylinder 27. A second spring 34 is fixed between the bottom of the first piston block 33 and the bottom of the connecting cylinder 27. The drive wheel 25 is hollow inside, and the interior of the connecting cylinder 27, the interior of the drive wheel 25, and the interior of each first cavity 3 are interconnected.

[0043] like Figure 8 , Figure 10 As shown; an elastic block 35 is fixedly connected to one end of the contact block 26 away from the interior of the drive wheel 25;

[0044] like Figure 5 , Figure 7 As shown; several support blocks 24 are slidably connected around the fixed shaft 21, and several abutment blocks 4 are fixedly connected to one side of each support block 24 inside the fixed shaft 21; a pull rod 41 is slidably connected inside the fixed shaft 21, one end of the pull rod 41 protrudes from the fixed shaft 21 and its cross-section is increased to be the same size as the cross-section of the fixed shaft 21; several receiving grooves 42 are opened around the pull rod 41 corresponding to the position of each abutment block 4; a second cavity 43 is opened inside the fixed shaft 21, and a protrusion is provided on the pull rod 41, the protrusion of the pull rod 41 being located inside the second cavity 43;

[0045] Block 4 is made of permanent magnets;

[0046] like Figure 5 , Figure 6 As shown; the fixed shaft 21 is provided with a meshing tooth at one end near the first block 22. The first block 22 is hollow inside and a meshing block 5 is provided inside the first block 22. The end of the meshing block 5 is provided with a meshing tooth. The meshing block 5 is slidably connected to the output shaft of the first motor 221. A third spring 51 is fixed between the end of the meshing block 5 near the first motor 221 and the inner wall of the first block 22.

[0047] During operation, the fixed shaft 21 passes through the second block 23 and can slide relative to it. The side of the first block 22 facing the second block 23 has a hole through which the fixed shaft 21 can pass. Initially, the first block 22 and the second block 23 jointly support the fixed shaft 21, meaning the fixed shaft 21 is located between the first block 22 and the second block 23. The support block 24 supports the roll of non-woven fabric. When the support block 24 extends, it contacts and presses against the inner wall of the roll, causing the fixed shaft 21 to rotate and drive the roll to rotate as well. When the support block 24 retracts, the fixed shaft 21 can be pulled out of the roll. When the contact block 26 retracts to the drive wheel 25, the contact block 26 does not contact the fixed shaft 21. The contact of the fixed shaft 21 does not affect its rotation. When the contact block 26 extends and contacts the fixed shaft 21, it cooperates with the drive wheel 25 to rotate, enabling the fixed shaft 21 to slide relative to the second block 23. A hydraulic rod can be installed inside the lifting platform 29. The top of the lifting platform 29 is fixedly connected to the top of the hydraulic rod. When the hydraulic rod extends, it raises the top of the lifting platform 29, thereby raising the non-woven fabric roll above the top of the lifting platform 29. The inclined plate 291 facilitates the transport of the non-woven fabric roll to the top of the lifting platform 29. When the first spring 31 is in its original position, the contact block 26 retracts into the first cavity 3. The first piston block 33 is made of a material that can be attracted by a magnet, such as iron, or a ring electromagnet 3. When energized, the first piston block 33 is attracted closer, and the second spring 34 extends. Hydraulic oil can be filled inside the connecting cylinder 27, the drive wheel 25, and each of the first chambers 3. When the first piston block 33 is attracted to its maximum displacement by the annular electromagnet 32, the contact block 26 will not detach from the first chamber 3. The elastic block 35 can be made of rubber to increase friction. The support block 24 will not detach from the fixed shaft 21. When the abutment 4 is located in the receiving groove 42, the support block 24 is in a retracted state. The second chamber 43, in conjunction with the protrusion on the pull rod 41, acts as a limit, preventing the pull rod 41 from detaching from the fixed shaft 21. When the pull rod 41 is pulled to its limit position, the abutment 4 is precisely... Located inside the receiving groove 42; the stop block 4 is made of a permanent magnet, and the pull rod 41 is made of a material that can be attracted by a magnet, such as iron; so that the stop block 4 is always in close contact with the pull rod 41, that is, when the stop block 4 is in the receiving groove 42, the support block 24 can retract; when the meshing teeth on the meshing block 5 mesh with the meshing teeth on the fixed shaft 21, the meshing block 5 can drive the fixed shaft 21 to rotate. At this time, the third spring 51 is in a compressed state, and the meshing block 5 is slidably connected to the output shaft of the first motor 221. It can only slide relative to each other and cannot rotate relative to each other. It can be connected by a keyway; the setting of the meshing block 5 and the third spring 51 ensures that the meshing teeth of the fixed shaft 21 and the meshing teeth of the meshing block 5 can mesh smoothly;

[0048] When uncut nonwoven fabric rolls need to be fed, the annular electromagnet 32 ​​is energized to attract piston block 33, causing contact block 26 to extend and spring 31 to stretch. Contact block 26 then contacts the pull rod 41 and fixed shaft 21. Motor 281 is then activated, driving drive wheel 25 and contact block 26 to rotate. This first pulls pull rod 41, aligning receiving groove 42 with abutment block 4, causing support block 24 to retract. Then, fixed shaft 21 slides, pulling it away from between blocks 22 and 23. The worker then uses inclined plate 291 to transport the uncut nonwoven fabric roll above lifting platform 29. Lifting platform 29 raises the roll, aligning the roll's opening with fixed shaft 21. Motor 281 reverses, causing fixed shaft 21 to move back between blocks 22 and 23 and pass through the opening of the uncut nonwoven fabric roll. One end of the fixed shaft 21 is inserted into the first block 22. The meshing teeth of the fixed shaft 21 mesh with the meshing teeth of the meshing block 5, causing the pull rod 41 to move into the fixed shaft 21, causing the stop block 4 to disengage from the receiving groove 42. The support block 24 extends out and contacts the nonwoven fabric roll to fix it. Then the lifting platform 29 descends, and the slitting and rewinding machine 1 slits the nonwoven fabric. The slit nonwoven fabric is rewound onto another fixed shaft 21. That is, one fixed shaft 21 releases the unslit nonwoven fabric roll, and the other fixed shafts 21 rewind the slit nonwoven fabric roll. During this process, the first motor 221 starts, driving each fixed shaft 21 to rotate accordingly, providing power for the release or rewinding of the nonwoven fabric roll by the fixed shaft 21. Similarly, when the slit and rewound nonwoven fabric roll needs to be unloaded from the fixed shaft 21, the fixed shaft 21 is pulled out, and the slit nonwoven fabric roll can be removed.

[0049] As a specific embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 3 As shown, the slitting and rewinding machine 1 is fixedly equipped with several receiving trays 6, each receiving tray 6 being located below each slitting nonwoven fabric roll.

[0050] During operation, the receiving tray 6 is located below the fixed shaft 21 of the rewinding nonwoven fabric. When unloading is required, the fixed shaft 21 is pulled out, and the receiving tray 6 can catch the cut nonwoven fabric roll, which can be taken out by the staff for easy operation.

[0051] A method for producing industrial nonwoven fabric, wherein the method employs an intelligent production equipment for industrial nonwoven fabric as described above, comprising the following steps:

[0052] S1: When it is necessary to feed the uncut nonwoven fabric roll, the annular electromagnet 32 ​​is energized to attract the first piston block 33 to approach, causing the contact block 26 to extend. Then, the second motor 281 is started. First, the pull rod 41 is pulled to make the receiving groove 42 correspond to the abutment block 4, and the support block 24 retracts. Then, the fixed shaft 21 is driven to slide, so that the fixed shaft 21 is pulled away from the first block 22 and the second block 23. Then, the worker transports the uncut nonwoven fabric roll to the top of the lifting platform 29. The lifting platform 29 raises the nonwoven fabric roll so that the hole of the nonwoven fabric roll is aligned with the fixed shaft 21. The second motor 281 reverses, and the fixed shaft 21 passes through the hole of the uncut nonwoven fabric roll, so that the meshing teeth of the fixed shaft 21 mesh with the meshing teeth of the meshing block 5. Then, the pull rod 41 moves into the fixed shaft 21, so that the abutment block 4 disengages from the receiving groove 42, and the support block 24 extends and contacts the nonwoven fabric roll to fix it.

[0053] S2: Then the lifting platform 29 descends, the slitting and rewinding machine 1 slits the non-woven fabric, and the slit non-woven fabric is rewound onto another fixed shaft 21. During this process, motor 221 starts and drives the fixed shaft 21 to rotate accordingly, providing power for the release or rewinding of the non-woven fabric roll on the fixed shaft 21.

[0054] S3: When the slit and rewound nonwoven fabric roll needs to be unloaded from the fixed shaft 21, the control support block 24 retracts, the fixed shaft 21 is pulled out, and the slit nonwoven fabric roll can be removed.
