Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production equipment, and specifically to a nonwoven fabric production system. Background Technology

[0002] In the nonwoven fabric production process, slitting equipment is used to cut the nonwoven fabric according to customer requirements. During slitting, the edges of the nonwoven fabric are trimmed. The waste material generated from the trimming is rolled up together with the required nonwoven fabric after slitting to form a waste roll, which is then removed for other uses. For general nonwoven fabric slitting, this method can reliably collect and process the waste material. However, for some waste materials with narrow trimmed edges, it is difficult to roll them up during winding, or the narrow rolls are prone to unraveling during subsequent processing, causing various inconveniences. Therefore, it is necessary to provide a more reliable processing method for these narrow waste material edges. Utility Model Content

Detailed Implementation

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0032] As used herein, the terms “parallel,” “perpendicular,” and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0033] like Figure 1 , 2 As shown, a nonwoven fabric production system includes a cutting device for slitting the nonwoven fabric, and an edge material collection device 100 for collecting the edge materials 001 formed by the cutting. The edge material collection device 100 includes a collection mechanism for gathering the two edge materials 001 cut from the fabric, a feeding mechanism for guiding the gathered edge materials 001, and an edge material winding mechanism for winding the guided edge materials 001. By using the collection mechanism, feeding mechanism, and edge material winding mechanism to gather and wind up the two cut fine edge materials 001, the system solves the problem of traditional fine edge materials 001 easily becoming scattered during subsequent processing, thus improving the reliability of edge material 001 collection.

[0034] like Figure 2 , 3 As shown: The edge material collection device 100 includes a receiving frame 105, which is located next to the cutting frame. The edge material winding mechanism includes a collecting shaft 132 that is detachably mounted on the receiving frame 105. A guiding mechanism for guiding the edge material to move along the length direction of the collecting shaft 132 is provided next to the collecting shaft 132. The edge material winding mechanism includes two oppositely arranged A1 movable mounting seats 133, which are movably mounted on the material receiving frame 105 in a horizontal direction perpendicular to the material collecting shaft 132. The material collecting shaft 132 includes an air expansion shaft section and assembly shaft sections respectively provided on the outer sides of both ends of the air expansion shaft section. The air expansion shaft section and the assembly shaft section are rotatably assembled and connected. A circular assembly plate is provided in the middle of the assembly shaft section. The outer diameter of the assembly plate is smaller than the outer diameter of the air expansion shaft section. A1 movable mounting seats 133 are provided with U-shaped A1 mounting slots. The opening of the A1 mounting slot is provided with an A1 blocking strip 134 to prevent the assembly shaft section from moving out of the A1 mounting slot. The A1 blocking strip 134 and the A1 movable mounting seats 133 are detachably assembled and connected.

[0035] When collecting edge material, the receiving paper tube is placed on the air-expansion shaft section, and the air-expansion shaft section is inflated to fix the receiving paper tube on the air-expansion shaft section. Then, one end of the edge material is fixed to the receiving paper tube and is wound onto the receiving paper tube as the receiving roll rotates. When assembling the collecting shaft 132, first open the A1 blocking strip 134, and assemble the assembly plate into the A1 mounting slot, so that the freedom of the collecting shaft 132 along its length is restricted. Then, assemble and connect the A1 blocking strip 134 and the A1 movable mounting seat 133 to achieve quick assembly of the collecting shaft 132. After the edge material is collected, open the A1 blocking strip 134, remove the collecting shaft 132, and deflate the air-expansion shaft section, so that the wound edge material roll, along with the receiving paper tube, is unloaded from the air-expansion shaft section. The A1 blocking strip 134 and the A1 movable mounting base 133 can be detachably assembled and connected by bolts or pins, or other methods can be selected according to the convenience of disassembly.

[0036] Further plans such as Figure 6 As shown: A receiving drive roller 131 is provided on the side of the collecting shaft 132. The receiving drive roller 131 is rotatably mounted on the receiving frame 105. One end of the receiving drive roller 131 is connected to the A1 receiving drive motor 138 through a transmission assembly. Two A1 movable mounting seats 133 are respectively assembled and connected to the two upper ends of the U-shaped connecting bracket 136. The receiving frame 105 is provided with an A1 mounting slide rail 135 for sliding assembly with the A1 movable mounting seats 133. The lower end of the U-shaped connecting bracket 136 is connected to an A1 translation adjustment cylinder 137 for adjusting its movement. The A1 translation adjustment cylinder 137 adjusts the collecting shaft 132 to move closer to or further away from the receiving drive roller 131.

[0037] In practice, the outer diameter of the take-up drive roller 131 is larger than the outer diameter of the take-up paper tube. The take-up drive roller 131 and the edge material wound on the take-up paper tube abut against each other, thereby driving the collecting shaft 132 to rotate. The A1 translation adjustment cylinder 137 adjusts the collecting shaft 132 to move away from the take-up drive roller 131 according to the edge material wound on the take-up paper tube, thereby realizing the continuous winding of the edge material.

[0038] like Figure 4 , 5As shown: the receiving drive roller 131 is located between the collecting shaft 132 and the feeding mechanism. The feeding mechanism includes a feeding mounting seat 110, which is movably mounted on the receiving frame 105 along the length of the collecting shaft 132. The feeding mounting seat 110 is connected to the A feeding adjustment assembly for adjusting its movement. The feeding mounting seat 110 is provided with a feeding unit for guiding the edge material. The feeding unit includes X1, X2, X3, X4, and X5 feeding sections arranged sequentially along the X1 direction. The X1 feeding section includes two X1 feeding rollers 111 spaced apart along the Y1 direction. The X1 direction is the horizontal direction where the receiving drive roller 131 points towards the collecting shaft 132, and the Y1 direction is a horizontal direction perpendicular to the X1 direction. The X1 feeding rollers 111 are vertically rotatably mounted on the feeding mounting base 110. The X2 feeding section includes X2 feeding rollers 112 arranged horizontally along the Y1 direction, which are rotatably mounted on the feeding mounting base 110. The X3 feeding section includes X2 feeding rollers 112 arranged horizontally along the Y1 direction. X3 guide roller 113 is rotatably mounted on X flip bracket, which is floatingly mounted on feed mounting base 110 via rotary gas spring 114 and tension spring 115. Rotary gas spring 114 drives X3 guide roller 113 to flip upward, and tension spring 115 drives X3 guide roller 113 to flip downward. X4 guide section includes X4 guide roller 117 arranged horizontally along Y1 direction, which is rotatably mounted on feed mounting base 110. X5 guide section includes two X5 guide rollers 118 spaced apart along Y1 direction, which are vertically rotatably mounted on feed mounting base 110. Through the guide unit with the above structure, the edge material is guided and the movement of feed mounting base 110 along Y1 direction is adjusted, so that the edge material can be evenly wound into a roll within the length range of the take-up paper tube. In detail: A1 fixed mounting bases 121 are provided on the outer sides of both ends of the moving range of the feeding mounting base 110. The A1 fixed mounting bases 121 are fixedly mounted on the receiving frame 105. Two A1 sliding rods 122 are provided between the two A1 fixed mounting bases 121. The feeding mounting base 110 is slidably mounted on the two A1 sliding rods 122. The A feeding adjustment assembly includes an A feeding adjustment transmission belt 123. A feeding adjustment wheels are rotatably mounted on the A1 fixed mounting bases 121 respectively. The two ends of the A feeding adjustment transmission belt 123 are assembled on the two A feeding adjustment wheels. The upper belt body of the A feeding adjustment transmission belt 123 is fixedly assembled and connected to the A assembly block 119 provided at the lower part of the feeding mounting base 110. One of the A feeding adjustment wheels is drivenly connected to the A feeding adjustment motor 126.

[0039] In the above scheme, the conveying direction of the A-feed adjusting transmission belt 123 is consistent with the Y1 direction. The movement of the A-feed adjusting transmission belt 123 is adjusted by the A-feed adjusting motor 126, which drives the feeding mounting seat 110 to reciprocate along the Y1 direction, thereby realizing reliable guiding and conveying of the edge material. The A assembly block 119 is also provided with an A1 mounting rod 116 for mounting and fixing the lower end of the tension spring 115, and the X flipping bracket is provided with an A2 short rod for mounting and fixing the upper end of the tension spring 115.

[0040] Further such as Figure 6 As shown: An A-sensor mounting bracket 124 is provided on the lower side of the feed mounting base 110. Two pairs of A1 detection sensors 125 are mounted on the A-sensor mounting bracket 124 to detect the position of the feed mounting base 110. The A1 detection sensors 125 are connected to the feed control device 104. The feed control device 104 adjusts the operating state of each mechanism, thereby achieving orderly and reliable winding of the edge material. The A1 detection sensors 125 ensure reliable support for the reciprocating movement of the feed mounting base 110. Figure 2 , 3 As shown: The feeding mechanism includes an X1 feeding section and an X2 feeding section installed at the lower part of the receiving frame 105, and an X3 feeding section installed at the upper part of the receiving frame 105. The X1 feeding section, X2 feeding section, and X3 feeding section are arranged sequentially along the Y1 direction. The X1 feeding section includes an X1 feeding roller 101 arranged horizontally along the Y1 direction. The X1 feeding roller 101 is rotatably mounted on the receiving frame 105. The X2 feeding section includes two X2 feeding rollers 102 arranged at intervals along the Y1 direction. The X2 feeding rollers 102 are arranged along the X1 direction. The height of the X2 feeding rollers 102 is greater than the height of the X1 feeding rollers 101. The ends of the X2 feeding rollers 102 away from the X1 feeding rollers 101 are rotatably assembled and connected to the receiving frame 105. The X3 feeding section includes an X3 feeding roller 103 arranged horizontally along the Y1 direction. The X3 feeding roller 103 is rotatably mounted on the receiving frame 105.

[0041] In the above scheme, the X1 feeding section, X2 feeding section, X3 feeding section, X1 guiding section, X2 guiding section, X3 guiding section, X4 guiding section, X5 guiding section, take-up drive roller 131, and collecting shaft 132 are sequentially arranged on the take-up frame 105 along the X1 direction. Through the arrangement of these components, the edge material can be reliably guided and wound up, ensuring the reliability of edge material winding. The edge material 001 is conveyed around the X1 feeding roller from below, then passes between the two X2 feeding rollers, and then is guided around the X3 feeding roller from above into the feeding mechanism. Within the feeding mechanism, the edge material is conveyed as follows... Figure 4As shown, the edge material 001 first passes between the two X1 guide rollers, then is conveyed around the upper side of the X2 guide roller, then around the lower side of the X3 guide roller, then around the upper side of the X4 guide roller, and finally passes between the two X5 guide rollers and exits the feeding mechanism. The edge material output from the feeding mechanism is conveyed around the upper side of the take-up drive roller 131, and then wound up on the collecting shaft 132.

[0042] like Figure 7 As shown: The collecting mechanism includes two sets of collecting sections 300. The two collecting sections 300 are respectively mounted on the cutting frame corresponding to the edge material output from the cutting equipment. The two collecting sections 300 have the same structure. Each collecting section 300 includes a vertically arranged collecting mounting plate 310. The collecting mounting plate 310 is provided with cantilevered mounting strips A1 311 and A2 312. The A1 mounting strips 311 and A2 mounting strips 312 are arranged vertically and alternately, with their cantilevered ends positioned near the center of the cutting equipment. A11 guide rollers 341 and A12 guide rollers 342 are arranged between the A1 and A2 mounting strips 311 and A12 respectively. The A11 guide rollers 341 and A12 guide rollers 342 are spaced apart along the X2 direction, where X2 is the direction of A1. The fixed end of the mounting strip 311 points towards the overhanging end. The A11 guide roller 341 and A12 guide roller 342 are vertically arranged and rotatably mounted on the A1 mounting strip 311 and A2 mounting strip 312 at both ends, respectively. The A21 guide roller 321 and A22 guide roller 322, which are rotatably mounted in an overhanging manner, are provided on the inner side of the A1 mounting strip 311 and A2 mounting strip 312 along the Y2 direction. The Y2 direction is a horizontal direction perpendicular to the X2 direction. The A21 guide roller 321 and A22 guide roller 322 are arranged correspondingly on top and bottom. The A31 guide roller 331 and A32 guide roller 332, which are rotatably mounted in an overhanging manner, are provided on the outer side of the A1 mounting strip 311 and A2 mounting strip 312 along the Y2 direction. The A31 guide roller 331 and A32 guide roller 332 are arranged correspondingly on top and bottom. The heights of guide rollers A21 321 and A31 331 are the same, and the heights of guide rollers A22 322 and A32 332 are the same. The height of guide roller A21 321 is less than the height of mounting strip A1 311, and the height of guide roller A22 322 is greater than the height of mounting strip A2 312.

[0043] The aforementioned inner and outer sides along the Y direction are relative to the inner and outer sides of the cutting device. In specific operation, follow... Figure 8The conveying method shown collects and gathers the two sides of the cut material. That is, one side of the material is transferred from one collecting section 300 to another collecting section 300 and then conveyed together with the other side of the material to the X1 feeding roller 101 for further transport. This application is mainly used for collecting narrower side materials. For wider side materials, they can also be rolled up together with the cut nonwoven fabric using traditional methods. Figure 8 As shown, the two material collection sections 300 are designated as the left material collection section 300 and the right material collection section 300, respectively. The materials pulled out by the cutting equipment are designated as the left material and the right material, respectively. The right material enters from the right port A11 and exits from the right port A12 on the right material collection section 300, then transfers to the left material collection section 300 where it enters from the left port A11 and exits from the left port A12. The left material directly enters from the left port A21 and exits from the left port A22 on the left material collection section 300. The right port A11 is formed by the combination of the guide rollers A11 341, A12 342, A21 321, and A22 322 on the right material collection section 300. The right port A12 is formed by the combination of the guide rollers A11 341, A12 342, A31 331, and A32 332 on the right material collection section 300. The left opening of A11 is formed by the enclosure of A11 guide roller 341, A12 guide roller 342, A21 guide roller 321, and A22 guide roller 322 on the left material collection section 300. The left opening of A12 is formed by the enclosure of A11 guide roller 341, A12 guide roller 342, A31 guide roller 331, and A1 mounting strip 311 on the left material collection section 300. The left opening of A21 is formed by the enclosure of the material collection mounting plate 310, A11 guide roller 341, A21 guide roller 321, and A1 mounting strip 311 on the left material collection section 300. The left opening of A22 is formed by the enclosure of the material collection mounting plate 310, A11 guide roller 341, A31 guide roller 331, and A32 guide roller 332 on the left. This method ensures reliable and stable feeding of materials from both the left and right sides, and also enables reliable collection of materials from the left and right sides.

[0044] Regarding the structure of the slitting equipment, such as Figure 9 As shown, the slitting equipment includes a conveying mechanism for transporting nonwoven fabric, a slitting mechanism for slitting the transported nonwoven fabric along its width, a winding mechanism for winding up the slitted nonwoven fabric, and an unloading mechanism for unloading the wound nonwoven fabric. The conveying mechanism has a conveying section that transports the nonwoven fabric at an angle, and the slitting mechanism is located beside the conveying section. The slitting mechanism includes slitting cutters, which are spaced apart along the width of the nonwoven fabric beside the conveying section. The slitting cutters cut the nonwoven fabric along its length. The slitting cutters are configured to be adjustable along the width of the nonwoven fabric, thus adapting to different slitting requirements and expanding the range of applications. Specifically, the conveying section includes an A1 conveying roller 204 and an A2 conveying roller 203 arranged above and below to guide the nonwoven fabric, with a cutter shaft 276 positioned between the A1 conveying roller 204 and the A2 conveying roller 203.

[0045] like Figure 13 As shown: The slitting mechanism also includes a cutter mounting beam 275, which is arranged along the width direction of the nonwoven fabric. The slitting cutter is movably and adjustablely mounted on the cutter mounting beam 275 along its length direction. The slitting cutter includes a circular cutter 272 and a cutter holder 271. The cutter 272 is rotatably mounted on the cutter holder 271, and the cutter holder 271 is movably mounted on the cutter mounting beam 275. The cutter holder 271 is equipped with a cutter adjustment assembly for adjusting the cutter 272 to move away from or closer to the nonwoven fabric. The slitting mechanism also includes a cutter shaft 276, which is arranged along the width direction of the nonwoven fabric. The cutter shaft 276 and the cutter mounting beam 275 are positioned on opposite sides of the nonwoven fabric. The slitting cutter also includes annular bottom cutters 277 spaced apart on the cutter shaft 276. The bottom cutters 277 are movably and adjustablely mounted on the cutter shaft 276 along its length direction. Each bottom cutter 277 corresponds to a circular cutter 272. Specifically, the cutter 272 is rotatably mounted on the cutter holder 271 and is driven to rotate by a drive assembly on the cutter holder 271. When the cutter 272 and the cutter holder 271 are arranged opposite each other, the rotating cutter 272 can reliably cut the nonwoven fabric passing between the cutter 272 and the cutter holder 271. The adjustment assembly can specifically be a propulsion adjustment assembly for adjusting the advance of the cutter 272 and / or a swing adjustment assembly for adjusting the left and right swing of the cutter 272. Specifically, it can be composed of a cylinder. If it is adjusted to swing left and right, the cutter 272 can be rotatably mounted on the cutter holder, which is rotatably mounted on the cutter holder 271 via a rotating shaft.

[0046] A suction device is installed beside the cutter 272 to remove dust and debris generated during cutting. Specifically, an openable and closable cover 273 can be installed outside the cutter 272, with a portion of the cutter blade located outside the cover 273. The suction device includes a suction pipe 207 arranged horizontally above the cutter shaft 276. Connecting pipes 274, spaced apart, are installed on the suction pipe 207 to communicate with each cover 273. The suction pipes 207 are connected to the suction device. This suction device reliably removes dust and other impurities generated during cutting, maintaining workshop cleanliness and improving product quality.

[0047] like Figure 12 , 13As shown: The winding mechanism includes a winding shaft 219, with both ends of the winding shaft 219 detachably mounted on two A-lifting seats. The A-lifting seats are vertically mounted on the slitting frame. The slitting frame is equipped with an A-lifting adjustment mechanism for adjusting the lifting of the A-lifting seats. A winding drive roller 205 is located on the lower side of the winding shaft 219, driving the nonwoven fabric roll on the winding shaft 219 to rotate. The roller surface of the winding drive roller 205 is in rolling contact with the outer surface of the nonwoven fabric roll. There are two winding drive rollers 205, and the winding shaft 219 is located on the upper side of the two winding drive rollers 205. Specifically, the winding shaft 219 can be an air-expanding shaft. A roll is sleeved on the winding shaft 219, and one end of the nonwoven fabric is then attached to the roll. The two winding drive rollers 205 drive the roll to rotate, thereby achieving reliable winding of the slit nonwoven fabric. The lifting adjustment mechanism raises the A lifting seat to accommodate the increased thickness of the nonwoven fabric as it is wound up, ensuring reliable winding. The A lifting seat is equipped with an assembly tube 218 for mounting to the end of the winding shaft 219. The assembly tube 218 is movably mounted on the A lifting seat along the length of the winding shaft 219. The A lifting seat is equipped with an A translation cylinder 216 for adjusting the movement of the assembly tube 218. By adjusting the movement of the assembly tube 218, the clamping and unloading of the winding shaft 219 can be adjusted, facilitating the loading of the winding shaft 219 and the unloading of the cut nonwoven fabric.

[0048] like Figure 9 , 10As shown in Figure 11, the winding of the cut nonwoven fabric is equivalent to winding multiple sets of nonwoven fabric simultaneously. Therefore, strict control of the nonwoven fabric's offset and tightness is required to prevent the wound nonwoven fabric from sticking together or running off-center. Furthermore, a pressure shaft 223 is provided on the upper side of the winding shaft 219. The pressure shaft 223 is arranged parallel to the winding shaft 219, and its two ends are rotatably mounted on lifting seats B. The lifting seats B are connected to a lifting adjustment mechanism B that adjusts their lifting. The pressure shaft 223 is used to press the nonwoven fabric on the winding shaft 219. When the winding shaft 219 winds the nonwoven fabric, it drives the pressure shaft 223 to rotate, pressing the nonwoven fabric tightly, thereby achieving reliable and tight winding of the nonwoven fabric, reducing looseness, and decreasing the probability of nonwoven fabric running off-center. Since lifting seats A and B are respectively installed at both ends of the winding shaft 219 and the pressing shaft 223, to ensure the reliability of winding, the lifting of the two lifting seats A and the two lifting seats B must be kept consistent. Therefore, a further solution is as follows: the slitting frame includes a left slitting frame section and a right slitting frame section 202. Vertically arranged assembly frame plates 201 are respectively installed on the left and right slitting frame sections 202. The surface of the assembly frame plate 201 is perpendicular to the winding shaft 219. A vertically arranged elongated A-shaped gap is provided on the assembly frame plate 201. The inner side plate of the assembly frame plate 201... A vertically arranged slide rail 210 is provided on the surface. The lifting seat A includes a slider 215 located inside the assembly frame plate 201 and an inverted U-shaped U-shaped part 214 located outside the assembly frame plate 201. The slider 215 is slidably assembled with the slide rail 210, and the U-shaped part 214 is fixedly assembled with the slider 215. The U-shaped part 214 extends to the lower side of the slider 215. The translation cylinder 216 is fixedly installed on the slider 215. The assembly tube 218 is located below the slider 215 and inside the U-shaped part 214. The assembly tube 218 is connected to the piston rod of the translation cylinder 216 through a connector. Upper sprocket 212 and lower sprocket are respectively provided on the upper and lower sides of the travel of the U-shaped component 214. The upper sprocket 212 and lower sprocket are connected by a transmission chain 213. The U-shaped component 214 and the transmission sprocket are fixedly connected. The U-shaped component 214 is connected to the piston cylinder of the lifting and adjusting cylinder 211 A provided on the outer plate of the assembly plate. The lower sprockets on the left and right cutting frame sections 202 are connected by transmission through the synchronous shaft 220 A. The transmission chain 213 is located on the periphery of the A gap section.The B lifting seat includes a B slider 222 located inside the assembly frame plate 201, above the A slider 215. The B slider 222 is slidably mounted on the A slide rail 210. The two ends of the pressing shaft 223 are rotatably mounted on the B slider 222. The B slider 222 is also equipped with a rotatably mounted B gear 224, which meshes with a vertically arranged B rack 225 fixedly mounted inside the assembly frame plate 201. The B slider 222 is connected to the piston cylinder of the B lifting adjustment cylinder 221 located on the inner surface of the assembly plate. The B gears 224 on the left and right cutting frame sections 202 are connected by a B synchronous shaft 226. The A synchronous shaft 220 and the B synchronous shaft 226 ensure reliable lifting adjustment of the A and B lifting seats, as well as synchronous lifting of the two A lifting seats and the two B lifting seats, preventing the nonwoven fabric from deviating during winding and sticking together.

[0049] like Figure 9 As shown: The unloading mechanism includes an unloading push shaft 255 and an unloading adjustment assembly. The unloading push shaft 255 is movably mounted on the slitting frame and is arranged parallel to the take-up shaft 219. The unloading adjustment assembly adjusts the unloading push shaft 255 to push the slit nonwoven fabric roll on the take-up shaft 219 out of the slitting mechanism. Both ends of the unloading push shaft 255 are suspended on the unloading assembly shaft 253 via swing arms 254. The unloading assembly shaft 253 is rotatably mounted on the slitting frame. One end of the unloading assembly shaft 253 on the slitting frame is also provided with a fixedly installed unloading adjustment arm 252. The unloading adjustment arm 252 and the swing arm 254 are arranged at an angle. The overhanging end of the unloading adjustment arm 252 is hinged to the piston cylinder of the unloading adjustment cylinder 251. The unloading adjustment cylinder 251 is arranged in an inverted position, and the cylinder body of the unloading adjustment cylinder 251 is hinged to the slitting frame. In this way, the unloading push shaft 255 can be adjusted to rotate around the unloading assembly shaft 253 by the unloading adjustment cylinder 251, thereby pushing the cut nonwoven fabric roll on the side to roll out of the cutting mechanism, thus realizing reliable and convenient unloading of the cut nonwoven fabric roll.

[0050] like Figure 13 , 14As shown, the slitting frame is also equipped with a guide platform 206 for removing the nonwoven fabric roll. The guide platform 206 and the unloading push shaft 255 are respectively located on both sides of the winding drive roller 205. The winding drive roller 205 is connected to the winding drive mechanism. The guide platform 206 facilitates the removal of the wound nonwoven fabric. The guide platform 206 also facilitates the placement of the winding shaft 219 between the two winding drive rollers 205. Furthermore, both ends of the take-up shaft 219 are provided with A guide members 283. A guide members 283 are connected to the piston cylinder of A1 cylinder 284. A1 cylinder 284 adjusts the guide members to lift and lower. A guide member 283 includes a U-shaped guide part and an inclined guide part that extends from one side of the U-shaped guide part toward the side close to the guide table 206 and gradually increases in height. A guide member 283 is located inside A slider 215, and the U-shaped guide part is located between the ends of the two take-up drive rollers 205. When placing the take-up shaft 219, cylinder A1 284 adjusts guide A 283 to a low position, placing the take-up shaft 219 on the guide table 206. Cylinder A1 284 then adjusts guide A 283 to a high position. As the inclined guide rises, it lifts the shaft end of the take-up shaft 219, causing it to roll and fall into the U-shaped guide. Then, guide A 283 is lowered, accurately, reliably, and conveniently placing the take-up shaft 219 on the two take-up drive rollers 205. Finally, the assembly tube 218 clamps the end of the take-up shaft 219. This solves the problem of the large distance between the take-up drive rollers 205 and the outer side of the slitting frame, making the assembly of the take-up shaft 219 inconvenient. The inner side of the A-guide component 283 is also provided with an A2 lifting guide roller 281 for lifting the take-up shaft 219. The length direction of the A2 lifting guide roller 281 is arranged perpendicular to the length direction of the take-up shaft 219. The A2 lifting guide roller 281 is rotatably mounted on the A2 lifting bracket. The A2 lifting bracket is fixedly mounted on the piston cylinder of the A2 lifting cylinder. The A2 lifting cylinder 282 adjusts the A2 lifting guide roller 281 to raise and lower. An A1 lifting guide roller 232 is provided on the outer side of the mounting plate 201 on the right-side slitting frame 202. The length direction of the A1 lifting guide roller 232 is perpendicular to the length direction of the take-up shaft 219. The A1 lifting guide roller 232 is rotatably mounted on the A1 lifting bracket 233. The A1 lifting bracket 233 is slidably assembled with the A1 lifting slide rail 234 provided on the outer plate of the mounting plate 201. The A1 lifting bracket 233 is connected to the piston cylinder of the A1 lifting cylinder 231 fixedly mounted on the mounting frame. The A1 lifting cylinder 231 adjusts the A1 lifting guide roller 232 for lifting and lowering. The size of the A-gap section allows the take-up shaft 219 to pass through. The take-up shaft 219 is specifically an air-expanding shaft. The A2 lifting guide roller 281 allows for reliable alignment between the end of the take-up shaft 219 and the mounting tube 218. By setting up the A2 lifting guide roller 281, the winding shaft 219 after winding can be pulled out from the drum by setting up the shaft pulling device.The specific operation is as follows: When assembling the take-up shaft 219, a sleeve of the appropriate size is fitted onto the take-up shaft 219. Then, the take-up shaft 219 is inflated to fix the sleeve in place. Next, the take-up shaft 219 with the sleeve is assembled to wind up the non-woven fabric. After winding is complete, the air in the take-up shaft 219 is released, and the take-up shaft 219 is pulled out from the sleeve. The shaft pulling device is a separate piece of equipment that can clamp the end of the take-up shaft 219 and pull the take-up shaft to move. The conveying mechanism also includes a tensioning shaft 242 located below the unloading push shaft 255 for tensioning the conveyed nonwoven fabric. The tensioning shaft 242 is rotatably mounted on a turning frame, which is equipped with a counterweight shaft 243 that matches the tensioning shaft 242. The turning frame is rotatably mounted on a cutting machine frame via axis A. The tensioning shaft 242 and the counterweight shaft 243 are positioned on opposite sides of axis A. The cutting machine frame is equipped with a turning adjustment cylinder 241 for adjusting the turning of the turning frame. Through the above-mentioned tensioning mechanism, the tension of the nonwoven fabric can be reliably adjusted, thereby adjusting the tension of the nonwoven fabric and preventing deviation.

[0051] In this invention, the nonwoven fabric roll is sequentially conveyed by a tensioning shaft and an A2 conveying roller to a space between a cutter and a bottom cutter for slitting. The slitted nonwoven fabric is then guided by an A1 conveying guide roller to a winding shaft 219 for winding. Two winding drive rollers 205 drive the winding shaft 219 to rotate and wind the fabric. A pressing shaft 223 winds the wound nonwoven fabric. The slitted nonwoven fabric roll is then unloaded by a discharge push shaft 255. The winding shaft 219 can be pulled out before or after unloading the nonwoven fabric roll using a shaft-pulling device. The above-mentioned solution provided by this invention can reliably slit nonwoven fabric with good slitting quality and can reliably unload the slitted nonwoven fabric roll, improving production efficiency and reducing production costs. A feeding device for unwinding the nonwoven fabric can also be installed upstream of the slitting equipment; the feeding device can be implemented according to the applicant's prior application.
