Detailed Implementation

[0026] 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.

[0027] 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.

[0028] like Figure 1As shown, a nonwoven fabric slitting device includes a feeding device 200 for feeding a roll of nonwoven fabric to be slitted and a slitting device 100 for slitting the nonwoven fabric. The slitting device 100 includes a conveying mechanism for conveying the released nonwoven fabric, a slitting mechanism for slitting the conveyed nonwoven fabric, a winding mechanism for winding the slitted nonwoven fabric, and an unloading mechanism for unloading the wound nonwoven fabric. Further, the conveying mechanism has a conveying section that conveys 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 direction of the nonwoven fabric beside the conveying section, and the slitting cutters cut the nonwoven fabric along its length direction.

[0029] The cutting blade is designed to be adjustable along the width of the nonwoven fabric, which can accommodate different cutting sizes and expand its adaptability. The specific conveying unit includes A1 conveying roller 104 and A2 conveying roller 103 arranged above and below to guide the nonwoven fabric, with the cutter shaft 176 positioned between A1 conveying roller 104 and A2 conveying roller 103.

[0030] like Figure 6 As shown, the slitting mechanism also includes a cutter mounting beam 175, which is arranged along the width direction of the nonwoven fabric. The slitting cutter is movably and adjustablely mounted on the cutter mounting beam 175 along its length direction. The slitting cutter includes a circular cutter 172 and a cutter holder 171. The cutter 172 is rotatably mounted on the cutter holder 171, and the cutter holder 171 is movably mounted on the cutter mounting beam 175. The cutter holder 171 is provided with a cutter adjustment assembly for adjusting the cutter 172 to move away from or closer to the nonwoven fabric. The slitting mechanism also includes a cutter shaft 176, which is arranged along the width direction of the nonwoven fabric. The cutter shaft 176 and the cutter mounting beam 175 are positioned on opposite sides of the nonwoven fabric. The slitting cutter also includes annular bottom cutters 177 spaced apart on the cutter shaft 176. The bottom cutters 177 are movably and adjustablely mounted on the cutter shaft 176 along its length direction, and each bottom cutter 177 corresponds to the circular cutter 172.

[0031] Specifically, the cutter 172 is rotatably mounted on the cutter holder 171 and is driven to rotate by a drive assembly on the cutter holder 171. When the cutter 172 and the cutter holder 171 are arranged opposite each other, the rotating cutter 172 can reliably cut the nonwoven fabric passing between the cutter 172 and the cutter holder 171. The adjustment assembly can specifically be a propulsion adjustment assembly for adjusting the advance of the cutter 172 and / or a swing adjustment assembly for adjusting the left and right swing of the cutter 172. Specifically, it can be composed of a cylinder. If it is adjusted to swing left and right, the cutter 172 can be rotatably mounted on the cutter holder, which is rotatably mounted on the cutter holder 171 via a rotating shaft.

[0032] A suction device is installed beside the cutter 172 to remove dust and impurities generated during cutting. Specifically, an openable and closable cover 173 can be installed outside the cutter 172, with a portion of the cutter blade located outside the cover 173. The suction device includes a suction pipe 107 arranged horizontally above the cutter shaft 176, with connecting pipes 174 spaced apart on the suction pipe 107 for communication with each cover 173. The suction pipes 107 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.

[0033] like Figure 5 , 6 As shown: The winding mechanism includes a winding shaft 119, with both ends of the winding shaft 119 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 105 is provided on the lower side of the winding shaft 119 to drive the nonwoven fabric roll on the winding shaft 119 to rotate. The roller surface of the winding drive roller 105 is in rolling contact with the outer surface of the nonwoven fabric roll. There are two winding drive rollers 105, and the winding shaft 119 is located on the upper side of the two winding drive rollers 105.

[0034] The take-up shaft 119 can be an air-expanding shaft. A roll is fitted onto the take-up shaft 119, and one end of the nonwoven fabric is then attached to the roll. Two take-up drive rollers 105 drive the roll to rotate, thereby achieving reliable take-up of the cut nonwoven fabric. The lifting adjustment mechanism adjusts the lifting seat A to raise it, thereby adapting to the increased thickness of the nonwoven fabric as it is taken up, ensuring the reliability of the take-up.

[0035] The lifting seat A is equipped with an assembly tube 118 for assembling with the shaft end of the take-up shaft 119. The assembly tube 118 is movably mounted on the lifting seat A along the length of the take-up shaft 119. The lifting seat A is equipped with a translation cylinder 116 for adjusting the movement of the assembly tube 118. By adjusting the movement of the assembly tube 118, the clamping and unloading of the take-up shaft 119 can be adjusted, facilitating the loading of the take-up shaft 119 and the unloading of the cut nonwoven fabric.

[0036] like Figure 2 , 3As shown in Figure 4, the winding of the cut nonwoven fabric is equivalent to winding multiple sets of nonwoven fabric simultaneously. Therefore, strict control of the nonwoven fabric offset and tightness is required to prevent the wound nonwoven fabric from sticking together or running off-center. Furthermore, a pressure shaft 123 is provided on the upper side of the winding shaft 119. The pressure shaft 123 is arranged parallel to the winding shaft 119, 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 123 is used to press the nonwoven fabric on the winding shaft 119. When the winding shaft 119 winds the nonwoven fabric, it drives the pressure shaft 123 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 119 and the pressing shaft 123, 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 102. Vertically arranged assembly frame plates 101 are respectively installed on the left and right slitting frame sections 102. The surface of the assembly frame plate 101 is perpendicular to the winding shaft 119. A vertically arranged elongated A-shaped gap is provided on the assembly frame plate 101. The inner side plate of the assembly frame plate 101... A vertically arranged slide rail 110 is provided on the surface. The lifting seat A includes a slider 115 located inside the assembly frame plate 101 and an inverted U-shaped U-shaped part 114 located outside the assembly frame plate 101. The slider 115 is slidably assembled with the slide rail 110, and the U-shaped part 114 is fixedly assembled with the slider 115. The U-shaped part 114 extends to the lower side of the slider 115. The translation cylinder 116 is fixedly installed on the slider 115. The assembly tube 118 is located below the slider 115 and inside the U-shaped part 114. The assembly tube 118 is connected to the piston rod of the translation cylinder 116 through a connector. Upper sprocket 112 and lower sprocket are respectively provided on the upper and lower sides of the travel of the U-shaped component 114. The upper sprocket 112 and lower sprocket are connected by a transmission chain 113. The U-shaped component 114 and the transmission chain 113 are fixedly connected. The U-shaped component 114 is connected to the piston cylinder of the lifting and adjusting cylinder 111 A provided on the outer plate of the assembly plate. The lower sprockets on the left and right cutting frame sections 102 are connected by a synchronous shaft 120 A. The transmission chain 113 is located on the periphery of the A gap section.The B lifting seat includes a B slider 122 located inside the assembly frame plate 101. The B slider 122 is positioned above the A slider 115 and is slidably mounted on the A slide rail 110. Both ends of the pressing shaft 123 are rotatably mounted on the B slider 122. A B gear 124 is also rotatably mounted on the B slider 122, meshing with a vertically arranged B rack 125 fixedly mounted inside the assembly frame plate 101. The B slider 122 is connected to the piston cylinder of the B lifting adjustment cylinder 121 located on the inner surface of the assembly plate. The B gears 124 on the left and right cutting frame sections 102 are connected via a B synchronous shaft 126. The A synchronous shaft 120 and B synchronous shaft 126 ensure reliable lifting adjustment of both the A and B lifting seats, as well as synchronous lifting of both A and B lifting seats, preventing nonwoven fabric from deviating during winding and sticking together.

[0037] like Figure 2 As shown: The unloading mechanism includes an unloading push shaft 155 and an unloading adjustment assembly. The unloading push shaft 155 is movably mounted on the slitting frame and is arranged parallel to the take-up shaft 119. The unloading adjustment assembly adjusts the unloading push shaft 155 to push the slitting nonwoven fabric roll on the take-up shaft 119 out of the slitting mechanism.

[0038] The two ends of the unloading push shaft 155 are suspended on the unloading assembly shaft 153 by the swing arm 154. The unloading assembly shaft 153 is rotatably mounted on the cutting frame. One end of the unloading assembly shaft 153 of the cutting frame is also provided with a fixedly installed unloading adjustment arm 152. The unloading adjustment arm 152 and the swing arm 154 are arranged at an angle. The cantilever end of the unloading adjustment arm 152 is hinged to the piston cylinder of the unloading adjustment cylinder 151. The unloading adjustment cylinder 151 is arranged in an inverted position. The cylinder body of the unloading adjustment cylinder 151 is hinged to the cutting frame.

[0039] In this way, the unloading push shaft 155 can be adjusted to rotate around the unloading assembly shaft 153 by the unloading adjustment cylinder 151, 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.

[0040] like Figure 6 , 7As shown, the slitting frame is also equipped with a guide platform 106 for removing the nonwoven fabric roll. The guide platform 106 and the unloading push shaft 155 are respectively located on both sides of the winding drive roller 105. The winding drive roller 105 is connected to the winding drive mechanism. The guide platform 106 facilitates the removal of the wound nonwoven fabric. The guide platform 106 also facilitates the placement of the winding shaft 119 between the two winding drive rollers 105. Furthermore, both ends of the take-up shaft 119 are provided with A guide members 183. A guide members 183 are connected to the piston cylinder of A1 cylinder 184. A1 cylinder 184 adjusts the guide members for lifting and lowering. A guide member 183 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 106 and gradually increases in height. A guide member 183 is located inside A slider 115, and the U-shaped guide part is located between the ends of the two take-up drive rollers 105. When placing the take-up shaft 119, cylinder A1 184 adjusts guide A 183 to a low position, placing the take-up shaft 119 on the guide table 106. Cylinder A1 184 then adjusts guide A 183 to a high position. As the inclined guide rises, it lifts the shaft end of the take-up shaft 119, causing it to roll and fall into the U-shaped guide. Then, guide A 183 is lowered, accurately, reliably, and conveniently placing the take-up shaft 119 on the two take-up drive rollers 105. Finally, the assembly tube 118 clamps the end of the take-up shaft 119. This solves the problem of the large distance between the take-up drive rollers 105 and the outer side of the slitting frame, making the assembly of the take-up shaft 119 inconvenient. The inner side of the A-guide component 183 is also provided with an A2 lifting guide roller 181 for lifting the take-up shaft 119. The length direction of the A2 lifting guide roller 181 is arranged perpendicular to the length direction of the take-up shaft 119. The A2 lifting guide roller 181 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 182 adjusts the A2 lifting guide roller 181 to raise and lower. An A1 lifting guide roller 132 is provided on the outer side of the mounting plate 101 on the right-side cutting frame 102. The length direction of the A1 lifting guide roller 132 is perpendicular to the length direction of the take-up shaft 119. The A1 lifting guide roller 132 is rotatably mounted on the A1 lifting bracket 133. The A1 lifting bracket 133 is slidably assembled with the A1 lifting slide rail 134 provided on the outer plate of the mounting plate 101. The A1 lifting bracket 133 is connected to the piston cylinder of the A1 lifting cylinder 131 fixedly mounted on the mounting frame. The A1 lifting cylinder 131 adjusts the A1 lifting guide roller 132 for lifting and lowering. The size of the A-gap section allows the take-up shaft 119 to pass through. The take-up shaft 119 is specifically an air-expanding shaft. The A2 lifting guide roller 181 is provided to ensure reliable alignment between the end of the take-up shaft 119 and the mounting tube 118. By setting up the A2 lifting guide roller 181, the winding shaft 119 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 119, a sleeve of the appropriate size is fitted onto the take-up shaft 119. Then, the take-up shaft 119 is inflated to fix the sleeve in place. Next, the take-up shaft 119 with the sleeve is assembled to wind up the non-woven fabric. After winding is complete, the air in the take-up shaft 119 is released, and the take-up shaft 119 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 119 and pull the take-up shaft to move.

[0041] The conveying mechanism also includes a tensioning shaft 142 located below the unloading push shaft 155 for tensioning the conveyed nonwoven fabric. The tensioning shaft 142 is rotatably mounted on a turning frame, which is equipped with a counterweight shaft 143 that matches the tensioning shaft 142. The turning frame is rotatably mounted on a cutting machine frame via axis A. The tensioning shaft 142 and the counterweight shaft 143 are positioned on opposite sides of axis A. The cutting machine frame is equipped with a turning adjustment cylinder 141 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.

[0042] like Figure 8 , 9As shown, the feeding device 200 includes a feeding frame, which comprises a left feeding frame section and a right feeding frame section. A feeding roller B1 203, a feeding roller B2 204, and a feeding drive roller 202 are arranged between the left and right feeding frame sections. The feeding rollers B1 203 and B2 204 are arranged vertically and horizontally, respectively. The height of the feeding roller B2 204 matches the height of the tensioning shaft 142. The feeding roller B1 203 is located outside the feeding drive roller 202, which drives the nonwoven fabric roll with slits to rotate and feed. The feeding drive roller 202 is arranged parallel to the winding shaft 119, and the feeding drive roller 202 can specifically be a rubber roller. The left and right feeding machine frames are respectively equipped with B slide rails. Each B slide rail is equipped with a B clamping seat 210 for assembling the end of the material shaft on the nonwoven fabric roll to be cut. The B clamping seat 210 is slidably mounted on the B slide rail. The B slide rail is arranged horizontally and perpendicular to the feeding drive roller 202. The B clamping seat 210 is connected to the B1 adjusting cylinder 217 for adjusting its movement. Specifically, the B1 adjusting cylinder 217 can be a rodless cylinder. The B clamping seat 210 is provided with a groove-shaped assembly groove 211 for assembling with the end of the material shaft. The inner end of the assembly groove 211 along the length of the material shaft is designated as end B1, and the outer end is designated as end B2. The groove wall at end B1 is provided with a V-shaped or U-shaped bayonet for assembling the material shaft. The groove at end B2 is provided with a B abutment block 212, which has a B abutment wedge surface. The height of the B abutment wedge surface gradually increases along the B direction, which is the direction from end B1 to end B2. The B clamping seat 210 is also provided with a pressure rod 213 for pressing the end of the material shaft. The pressure rod 213 is installed in a flip-type manner through a B flip bracket 214. The B flip bracket 214 is connected to a B flip adjusting cylinder 218 for adjusting its flipping. The pressure rod 213 is a circular rod. The inner side of the B-clamping base 210 is provided with a vertically arranged B-mounting plate 215, on which an identification code 216 is provided. The identification code 216 can be a barcode or a QR code. The identification code 216 enables precise management of non-woven fabric materials. The non-woven fabric is loaded via an AVG lifting trolley.

[0043] The B clamping seat 210 with the above-described structure allows for reliable clamping and centering of the material shaft, improving the assembly efficiency of the nonwoven fabric roll. The B1 adjusting cylinder 217 adjusts the position of the B clamping seat 210 according to the amount of nonwoven fabric on the material shaft, enabling the feeding drive roller 202 to contact the nonwoven fabric roll and drive it to feed. A more preferred embodiment is that the left and right feeding frames are slidably mounted on the base 201 along the B direction. The left and right feeding frames are connected to the B-movement adjusting cylinder, which adjusts their movement. An A sensor 161 is located beside the tensioning shaft 142 to detect the conveyed nonwoven fabric. The information detected by the A sensor 161 includes the offset of the nonwoven fabric. The control device adjusts the movement of the left and right feeding frames along the B direction based on the signal detected by the A sensor 161. Since the nonwoven fabric roll with slits is not perfectly centered, the above-mentioned correction operation allows for reliable adjustment of the nonwoven fabric, thereby improving the slit quality.

[0044] In this invention, a nonwoven fabric roll with slitting mechanism is mounted on clamping seat 210 (B). The nonwoven fabric roll is rotated and unloaded by a feeding drive roller 202. The released nonwoven fabric is sequentially conveyed by feeding rollers 203 (B1), 204 (B2), tensioning shaft 142, and conveying roller 103 (A2) to the space between cutter 172 and bottom cutter 177 for slitting. The slitting nonwoven fabric is then conveyed by conveying guide roller A1 to winding shaft 119 for winding. Two winding drive rollers 105 drive winding shaft 119 to rotate and wind the fabric. Pressing shaft 123 winds the wound nonwoven fabric. The slitting nonwoven fabric roll is then unloaded by unloading push shaft 155. The winding shaft 119 can be pulled out before unloading the nonwoven fabric roll using a shaft pulling device, or it can be pulled out after unloading the nonwoven fabric.

[0045] The above-mentioned solution provided by this utility model can reliably cut non-woven fabric with good cutting quality, and can reliably unload the cut non-woven fabric rolls, thereby improving production efficiency and reducing production costs.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
