[0030] Referring to Figures 1 to 9 An automatic continuous winding device for a spunlace nonwoven fabric, comprising a winding assembly and an auxiliary roller replacement assembly, wherein,

[0031] As shown in Figures 1 to 3 The winding assembly comprises a winding support 110 and a mounting disc 120, the mounting disc 120 is assembled on one side of the winding support 110 by fixing a main shaft 130 at the center thereof, and the other side of the mounting disc 120 not connected with the main shaft 130 is circularly arrayed with three winding rollers 140 with the center as the center, the winding support 110 is provided with a mounting hole 111 for the main shaft 130 to pass through and a bearing (not shown in the figure), and a first motor for driving the mounting disc 120 to rotate is mounted on the winding support 110.

[0032] Thus, the mounting disc 120 forms three stations by the positions of the three winding rollers 140, which are respectively a winding station in the center of the mounting disc 120, and taking the replacement of the winding roller 140 by the clockwise rotation of the mounting disc 120 as an example, the winding roller 140 on the right side of the winding station is in an unloading station, and the winding roller 140 on the left side of the winding station is in a loading station. Among them, the three winding rollers 140 are uniformly arranged on the mounting disc 120 with a central angle of 120°, and the main shaft 130 can be rotated by 120° by the first motor and the controller to replace the winding roller 140, the winding roller 140 wound with enough nonwoven fabric is rotated to the unloading station, the winding roller 140 is unloaded by the worker for the next process, and the empty winding roller 140 is installed in the loading station, waiting for the next step into the winding station, at this time the winding station is carrying out the winding work of the nonwoven fabric.

[0033] The auxiliary roller replacement assembly comprises a lateral support 210 fixed on one side of the winding roller 140 and a pair of circular arc guide rails 220, a pair of the circular arc guide rails 220 are respectively fixed on the top of the lateral support 210 corresponding to the two end faces of the winding roller 140, and when the winding roller 140 rotates to the highest position with the mounting disc 120, the center of the circular arc guide rail 220 coincides with the center position of the winding roller 140 at this time.

[0034] A pair of the circular arc guide rails 220 are respectively provided with a circular arc sliding sleeve 230, and the circular arc sliding sleeves 230 are installed with a compression roller 250 parallel to the winding roller 140 through a connecting support 240, the compression roller 250 can be radially compressed on the roller surface of the winding roller 140 by the extension of the connecting support 240; the circular arc sliding sleeve 230 can be driven to slide along the circular track extended from the circular arc guide rail 220; and the connecting support 240 is further provided with a third motor for driving the compression roller 250 to rotate.

[0035] In the present application, when replacing the roller,Figure 5 As shown, the winding roller 140, after winding is completed, is rotated to the unloading roller station by the first motor, while the winding roller 140 at the upper roller station is simultaneously rotated to the winding station. The nonwoven fabric is thus pulled around the upper arc surface of the winding station. The control pressure roller 250 radially presses the winding roller 140 at the winding station. At this time, the nonwoven fabric is clamped by the pressure roller 250 and the winding roller 140, so that the pressure roller 250 itself does not rotate, but revolves around the center of the winding roller 140 through the connecting bracket 240. The nonwoven fabric is then clamped and wound onto the lower arc surface of the winding station. The pressure roller 250 revolves to the winding end 260 of the nonwoven fabric located on the upper arc surface of the winding station. At this time, the nonwoven fabric can be cut between the winding station and the unloading roller station. The cut nonwoven fabric naturally hangs down on the unloading roller station.

[0036] Immediately afterwards, such as Figure 6 As shown, the clamping force between the clamping roller 250 and the take-up roller 140 is maintained by the extension of the connecting bracket 240. At the same time, the clamping roller 250 is controlled to rotate counterclockwise and the take-up roller 140 to rotate clockwise, and the two rotate in opposite directions at the same linear speed. Since the clamping roller 250 is now close to the winding end 260 of the nonwoven fabric, the broken end of the nonwoven fabric is fed into the gap between the winding end 260 and the take-up roller 140. As the take-up roller 140 rotates, it is covered on the inside. After the clamping roller 250 and the take-up roller 140 rotate in opposite directions for several turns, the nonwoven fabric is firmly wound on the take-up roller 140. The clamping roller 250 can be removed by the retraction of the connecting bracket 240, and the roller changing process is completed.

[0037] It is worth noting that the cooperation of the arc guide rail 220 and the arc sliding sleeve 230 provides guidance and limit for the above-mentioned "revolution" action of the pressing roller 250. Therefore, the rotation of the arc guide rail 220 and the arc sliding sleeve 230 must be centered on the center of the winding station to ensure the stable clamping of the nonwoven fabric by the pressing roller 250 and the take-up roller 140. At the same time, the connecting bracket 240 can control the appropriate clamping force through its extension and retraction. Its extension and retraction can be achieved by existing devices such as pneumatic telescopic cylinders, which will not be described in detail here.

[0038] In addition, the roller surface of the pressure roller 250 can also be made of materials such as rubber to increase the friction between it and the nonwoven fabric, and to provide elastic cushioning for the pressing state between the pressure roller 250 and the take-up roller 140.

[0039] Combination Figure 4As shown, in order to quickly and conveniently disassemble and assemble the winding roller 140 at the unloading station and the loading station, the mounting disc 120 is provided with a second motor 150 for driving the winding roller 140 to rotate, the second motor 150 is assembled on the other side of the mounting disc 120 through a mounting bracket 160, and the mounting disc 120 is provided with a through hole 121 corresponding to the winding roller 140, and the output shaft of the second motor 150 passes through the through hole 121 to drive the winding roller 140, and the end of the winding roller 140 is fixedly connected with the connecting head 170.

[0040] Further, the winding roller 140 comprises a roller shaft 141 and a roller cylinder 142 for winding the non-woven fabric, the roller shaft 141 rotates synchronously with the roller cylinder 142, the end of the roller shaft 141 is keyed connected with the connecting head 170, and the roller shaft 141 is further sleeved with a locking sleeve 180, the locking sleeve 180 is threadedly connected with the connecting head 170 to lock the roller shaft 141, and the two ends of the connecting head 170 passing through the through hole 121 are fixed on the mounting bracket 160 through a bearing structure, through the above structure, the winding roller 140 only needs to be quickly disassembled and assembled by screwing the locking sleeve 180.

[0041] In some embodiments, as shown, Figure 7 As shown, the cutting knife 270 can be automatically installed to cut the non-woven fabric to improve the efficiency of changing the roller, the connecting bracket 240 is provided with a clamping groove 271 for assembling the cutting knife 270 on the side of the pressing roller 250, the clamping groove 271 is externally provided with a bolt 272 for fixing the cutting knife 270, and the bolt 272 is sleeved with a buffer spring 273 in the clamping groove 271 for pressing the cutting knife 270, so that when the cutting knife 270 touches the roller surface of the winding roller 140, the blade end of the cutting knife 270 can slide relative to the winding roller 140.
