Detailed Implementation

[0028] 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.

[0029] 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.

[0030] like Figure 1As shown, a conveying device for producing nonwoven fabric is located between a cutting device for cutting nonwoven fabric rolls 000 and a packaging device for packaging the cut nonwoven fabric rolls 000. The conveying device includes a conveyor frame 101 and a receiving mechanism mounted on the conveyor frame 101. The conveyor frame 101 is movably installed along direction A, which is the distance direction between the packaging device and the cutting device. The receiving mechanism includes a support groove for supporting the nonwoven fabric rolls 000. The support groove is a horizontally arranged V-shaped groove or U-shaped groove. The support groove is rotatably mounted on the conveyor frame 101 via an assembly shaft A. The length direction of the assembly shaft A and the length direction of the support groove are both perpendicular to direction A. The support groove is connected to an adjustment mechanism A1 for adjusting its rotation. The conveyor frame 101 is connected to an adjustment mechanism A2 for adjusting its movement along direction A.

[0031] The cut nonwoven fabric roll 000 is received by a support groove. When the cutting equipment needs to receive material, the cutting equipment is moved closer to the cutting equipment, and the support groove is flipped to the same side. This ensures that the groove wall of the support groove closest to the cutting equipment and the unloading path of the nonwoven fabric roll 000 on the cutting equipment are aligned, allowing the nonwoven fabric roll 000 to be easily transferred into the support groove. After the nonwoven fabric roll 000 is unloaded from the cutting equipment, the support groove is flipped so that the groove opening faces upward. Then, the support groove moves the nonwoven fabric roll 000 closer to the packaging equipment. Once in position, the support groove is flipped to the same side, ensuring that the groove wall of the support groove closest to the packaging equipment and the loading path of the nonwoven fabric roll 000 on the packaging equipment are aligned, allowing the nonwoven fabric roll 000 to be easily transferred to the packaging equipment. This achieves fast and reliable conveying of the nonwoven fabric roll 000.

[0032] Further plans such as Figure 2 , 3 As shown: The support groove includes two opposing groove wall sections, A1 and A2, which are respectively composed of roller conveyors A1 and A2, arranged in a V-shape. The A1 roller conveyor includes A1 guide rollers 111, and the A2 roller conveyor includes A2 guide rollers 112. Both A1 and A2 guide rollers 111 and A2 guide rollers 112 are installed and rotated perpendicular to direction A. By using roller conveyors A1 and A2 to form the groove wall sections, the position of the nonwoven fabric roll 000 within the support groove can be adjusted to meet the feeding requirements of the packaging equipment. Both ends of A1 guide roller 111 and A2 guide roller 112 are rotatably mounted on A movable mounting frame 102. The drive of A1 guide roller 111 and A2 guide roller 112 can be a general chain drive or gear drive. Preferably, an electric roller (electric drum) is used to form A1 guide roller 111 and A2 guide roller 112.

[0033] Both ends of the support groove are equipped with A-baffles 103 to prevent the nonwoven fabric roll 000 from moving out of the support groove. A1 and A2 limiting components are respectively installed on the lower sides of roller conveyors A1 and A2, which limit the rotation of the support groove to the correct position. The baffles prevent the nonwoven fabric roll 000 from falling off the conveying equipment during transport, improving the reliability of the conveying process. The A1 and A2 limiting components reliably solve the problem of overturning transition of the support groove, improving the reliability of overturning adjustment. The A1 and A2 limiting components can be height-adjustable and can be made of elastic materials such as rubber.

[0034] like Figure 4 , 5As shown, it also includes an A3 adjustment mechanism, which is used to adjust the A1 and A2 roller conveyors so that the nonwoven fabric roll 000 in the support groove moves along the length of the groove. The A1 and A2 roller conveyors are mounted on the A movable mounting frame 102, which is rotatably mounted on the frame via the A assembly shaft. The A1 adjustment mechanism is connected to the A movable mounting frame 102. The A movable mounting frame 102 is a V-shaped mounting frame. The lower part of the A movable mounting frame 102 is provided with an A assembly connector, which is hinged to one end of the A connecting rod 106. The A1 adjustment mechanism includes an A1 crank, one end of which is hinged to the other end of the A connecting rod 106. The other end of the A1 crank is fixedly mounted on the output shaft of the A1 reducer. The A1 reducer is connected to the A1 drive motor 107 mounted on the conveyor frame 101. Four wheels 104 are installed at the bottom of the conveyor frame 101. These wheels are divided into two groups, with two wheels 104 in each group spaced apart along the length of the support groove. The two wheels 104 in the same group are connected by a drive shaft A. Each of the two A-drive wheels has an A1 drive chain, which is connected by another A-drive chain. One of the A-drive shafts has an A2 drive chain. The A2 adjustment mechanism includes an A2 drive motor 105 mounted on the conveyor frame 101 and an A2 reducer connected to the A2 drive motor 105. An A3 sprocket is mounted on the output shaft of the A2 reducer, and the A2 and A3 sprockets are connected by the A2 drive chain. Specifically, a guide rail is installed on the ground between the cutting equipment and the packaging equipment, with the wheels 104 rolling in conjunction with the guide rail. A power supply component is also installed between the cutting equipment and the packaging equipment to provide power to the conveyor equipment during movement. It also includes an A1 detection assembly for detecting the rotational state of the A movable mounting frame 102. The A1 detection assembly includes an A detection pointer 121 suspended and fixedly mounted at the end of the A movable mounting frame 102. The A detection pointer 121 is arranged at the intersection of the A1 roller conveyor and the A2 roller conveyor. An A detection mounting plate is provided on the conveyor frame 101 corresponding to the A detection pointer 121. The A detection mounting plate is provided with an arc-shaped A detection mounting gap. Two A1 detection sensors 122 are provided on the A detection mounting gap. The two A1 detection sensors 122 correspond to the A... Two A1 detection sensors 122 are respectively set at both ends of the movement trajectory of the suspension end of the detection pointer 121. The two A1 detection sensors 122 are used to detect the suspension end of the outer A detection pointer 121. The two A1 detection sensors 122 are connected to the control device. Vertical A mounting parts are also set on both sides of the A detection mounting plate. A abutment switch 123 is set on the upper end of the vertical A mounting parts. When the rotation angle of the A movable mounting frame 102 exceeds the preset angle, the A movable mounting frame 102 abuts against the A abutment switch 123 to adjust the A movable mounting frame 102 to stop flipping.The conveying equipment also includes a control device. Through the control device and sensor assembly, the position and status of the conveyor frame 101 are precisely detected, allowing operators to precisely control the conveying device using the control device. It also includes an A2 detection assembly for detecting the rotational state of the conveyor frame 101. An A2 mounting bracket 124 is provided on the outer side of the end of the conveyor frame 101. The A2 detection assembly includes A2 detection sensors 125 respectively installed at both ends of the A2 mounting bracket 124, and the A2 detection sensors 125 are connected to the control device.

[0035] like Figure 1 , 5 As shown: An auxiliary unloading mechanism is also included, used to adjust the nonwoven fabric roll 000 to be removed from the support groove and move it out of the support groove. An A-feeding mechanism is also provided to push the nonwoven fabric roll 000 in the support groove towards the packaging equipment. The specific A-feeding mechanism can be implemented as follows: The A1 roller conveyor is arranged near the cutting equipment. The A1 roller conveyor also includes an A-feeding roller 113, located in the middle of the A1 roller conveyor. The A1 guide rollers 111 and the A-feeding roller 113 are arranged in parallel, with the A-feeding roller 113 located between the two A1 guide rollers 111. The A-feeding roller 113 is rotatably mounted on the A-feeding bracket 114, which is rotatably mounted on the A-movable mounting frame 102. The A-movable mounting frame 102 is also equipped with an A-feeding drive motor 115 that drives the A-feeding bracket 114 to rotate. Multiple A-feeding rollers 113 can be provided, with each A-feeding roller 113 spaced apart along the length of the support groove. Each A-feeding roller 113 is connected to a respective A-feeding drive motor 115. Since the cutting equipment cuts the wider nonwoven fabric roll 000 into smaller nonwoven fabric rolls 000, multiple nonwoven fabric rolls 000 are unloaded from the cutting equipment and transferred to the support groove. Packaging of the nonwoven fabric rolls 000 is not completed in one step; generally, the nonwoven fabric rolls 000 are transferred one by one to the packaging equipment. Therefore, the nonwoven fabric rolls 000 are moved to the middle of the support groove via the A1 and A2 roller conveyors. Then, by adjusting the A-feeding rollers 113 to rotate, the nonwoven fabric rolls 000 located in the middle of the support groove are pushed out and moved to the packaging equipment, thereby achieving reliable and orderly removal of each nonwoven fabric roll 000 from the support groove and improving the reliability of the conveying process.

[0036] Regarding the structure of the slitting equipment, such as Figure 6As 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. Conveyor rollers A1 204 and A2 203 are arranged horizontally and parallel to each other, and both conveyor rollers A1 204 and A2 203 are arranged perpendicular to the A direction.

[0037] like Figure 10 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.

[0038] 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.

[0039] like Figure 9 , 10 As 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.

[0040] like Figure 6 , 7As shown in Figure 8, 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 the probability of loose nonwoven fabric and 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.

[0041] like Figure 6 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.

[0042] like Figure 10 , 11As 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.

[0043] 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.
