[0002] Spunlace nonwoven fabric is made by spraying high-pressure fine water flow onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber web and giving it a certain strength. The resulting fabric is a spunlace nonwoven fabric.

[0003] After searching. The Chinese patent with publication number: CN220952381U discloses a spunlace mechanism for spunlace nonwoven fabrics that is convenient for recycling water, wherein a chamber cover is provided on the upper surface of the spunlace chamber, a main roller is provided at the middle position inside the spunlace chamber, steering rollers are symmetrically provided on both sides of the spunlace chamber, the bottom of the spunlace chamber is a conical structure, a water return port is provided at the bottom of the conical structure of the spunlace chamber, and inlet and outlet ports are provided on both sides of the spunlace chamber; the chamber cover includes a connecting plate, an inclined plate and a top plate, inclined plates are symmetrically provided on both sides of the top plate, a connecting plate is provided at the outer end of the inclined plate, the connecting plate, the inclined plate and the top plate are an integrated structure, the chamber cover is connected to the spunlace chamber through a connecting plate and bolts and nuts, and a plurality of spunlace nozzles are installed on the top plate and the inclined plates on both sides, and the spunlace nozzles are all facing the main roller.

[0004] Based on the above search and combined with actual problems, it was found that the spunlace device for spunlace processing of non-woven fabrics sprays high-speed water flow onto the non-woven fabrics through several fixed nozzles. The bamboo fibers on the non-woven fabrics are entangled by the impact of the water flow, but the entanglement effect is not good, resulting in the overall strength of the non-woven fabrics being low. In addition, the fixed nozzles spraying water flow will cause the spraying position to be uneven, resulting in more positions not being sprayed by water flow, which will make it difficult for the fibers in some positions to be effectively entangled, further affecting the overall strength of the non-woven fabric.

[0015] The present invention also provides a method for producing a bamboo fiber spunlace nonwoven fabric, which specifically comprises the following steps:

[0016] Step 1: The water pump of the hydroentanglement device draws water from an external water source into the inner side of the upper chamber, so that the water inside the upper chamber generates a certain strength of water pressure. Under the action of the water pressure, the water flows into the inner side of each flow channel through multiple water inlets on the outer side of each fixed tube, and is ejected outward through the jet port at the lower end of each flow channel. The diameter of the jet port is smaller than the diameter of the flow channel, so the flow rate of the water will increase when it passes through the jet port, so that the water forms a fine high-speed water flow. Multiple flow channels are arranged inside the multiple rotating columns and the rotating disk. Several high-speed water flows can hydroentangle the surface of the bamboo fiber non-woven fabric, so that the bamboo in the bamboo fiber non-woven fabric is The fibers can be entangled with each other, and at the same time, the driving motor of the transmission mechanism drives the driven gear to rotate, and the driven gear drives the driving gear to rotate through the teeth, and the driving gear drives a rotating column fixed thereto to rotate, and the rotating column drives the transmission pulley on its outer side to rotate, and the transmission pulley drives the adjacent transmission pulley to rotate through the transmission belt, thereby driving the adjacent rotating column to rotate, and so on, each rotating column can be driven to rotate synchronously, so that the water flow ejected from the inner side of multiple flow channels is more evenly ejected at various positions of the bamboo fiber non-woven fabric, thereby improving the entanglement uniformity between the bamboo fibers therein;

[0017] Step 2, multiple kneading mechanisms on the inner side of the spicing roller and the reciprocating mechanisms therein rotate simultaneously with the spicing roller, and the central gear and the end cover are fixed, wherein the planetary gear of the reciprocating mechanism rotates around the central gear while the spicing roller rotates, and at the same time, through the meshing of the teeth between the planetary gear and the central gear, the planetary gear will generate self-rotation, thereby driving the cam shaft to rotate, and the cam shaft drives the cylindrical reciprocating cam to rotate, and when the cylindrical reciprocating cam rotates, the sliding plate of the kneading mechanism is driven to move back and forth linearly along the outer sides of the two guide rods through the sliding cooperation between the guide groove and the sliding pin on its outer side, and the sliding plate drives the multiple fixed horizontal plates fixed thereto to move back and forth linearly, and each fixed horizontal plate drives multiple kneading disks on one side thereof to move back and forth, and each kneading disk reciprocates on the inner side of the corresponding water hole, and one side of each kneading disk is provided with an arc surface flush with the outer side of the spicing roller, so that when the multiple kneading disks reciprocate, the side where the bamboo fiber non-woven fabric is attached to the spicing roller is continuously kneaded, thereby enhancing the entanglement strength between the bamboo fibers;

[0018] Step 3: While the bamboo fiber non-woven fabric drives the two guide rollers to rotate, each guide roller drives the corresponding active pulley of the intermittent stop mechanism to rotate, and the active pulley drives the driven pulley and the driven shaft to rotate through the synchronous belt, and the driven shaft drives the eccentric wheel to rotate. The eccentric wheel can push the brake block to one side of the brake disc once every rotation. At the same time, under the guidance of the slide bar and the inclined groove, the arc groove on one side of the brake block is closely attached to the outer side of the brake disc. The brake disc will stop rotating due to the pressure of the brake block and the arc groove, so that The spicing roller connected to the brake disc stops rotating, and each time the eccentric wheel pushes the brake block, the brake disc and the spicing roller can be stopped intermittently, so that when the bamboo fiber non-woven fabric drives the spicing roller to rotate, the spicing roller can be paused intermittently. Since the bamboo fiber non-woven fabric keeps moving, when the spicing roller stops rotating, the bamboo fiber non-woven fabric continues to move and slides a certain distance along the outside of the spicing roller, thereby continuously changing the contact position between the bamboo fiber non-woven fabric and the spicing roller, so that multiple rubbing discs rub different positions of the bamboo fiber non-woven fabric.

[0019] The present invention provides a bamboo fiber spunlace nonwoven fabric production device and a preparation method thereof by improvement, which has the following improvements and advantages compared with the prior art:

[0020] First, the present invention uses multiple kneading mechanisms and reciprocating mechanisms in the spunlacing roller. When the spunlacing roller rotates, the multiple kneading disks in the kneading mechanism can continuously reciprocate, and the side of the bamboo fiber non-woven fabric that is in contact with the spunlacing roller can be continuously kneaded. Since the bamboo fibers in the bamboo fiber non-woven fabric are impacted to the other side by the high-speed water flow, the arc-shaped surfaces on one side of the multiple kneading disks can further enhance the entanglement strength between the bamboo fibers when kneading the bamboo fibers on the other side, thereby further improving the overall strength of the bamboo fiber non-woven fabric.

[0021] Secondly, the present invention uses an intermittent stop mechanism. When the bamboo fiber non-woven fabric drives the entanglement roller to rotate, the entanglement roller can be intermittently stopped. Since the bamboo fiber non-woven fabric keeps moving, when the entanglement roller stops, the bamboo fiber non-woven fabric continues to move and slides a certain distance along the outside of the entanglement roller, thereby continuously changing the contact position between the bamboo fiber non-woven fabric and the entanglement roller, so that each position of the bamboo fiber non-woven fabric can be rubbed by multiple rubbing disks, thereby improving the uniformity of rubbing, making the bamboo fibers on the bamboo fiber non-woven fabric more evenly entangled, and further improving the overall strength of the bamboo fiber non-woven fabric.

[0022] Thirdly, the present invention can drive each rotating column and rotating disk to rotate synchronously through the water spunlace device and the transmission mechanism therein, thereby driving the flow channels therein to rotate, so that the water flow ejected from the inner sides of multiple flow channels can be more evenly sprayed at various positions of the bamboo fiber non-woven fabric, thereby improving the entanglement uniformity between the bamboo fibers therein, thereby improving the water spunlace processing quality of the bamboo fiber non-woven fabric.

[0050] Embodiment 2:

[0051] This embodiment also provides a method for producing a bamboo fiber spunlace nonwoven fabric, which specifically comprises the following steps:

[0052] Step 1: The water pump 102 of the water spunlace device draws water from an external water source into the inner side of the upper chamber 103, so that the water inside the upper chamber 103 generates a certain strength of water pressure. Under the action of the water pressure, the water flows into the inner side of each flow channel 109 through the multiple water inlets 108 outside each fixed pipe 107, and is ejected outward through the jet port 110 at the lower end of each flow channel 109. The diameter of the jet port 110 is smaller than the diameter of the flow channel 109, so the flow rate of the water will increase when it passes through the jet port 110, so that the water forms a fine high-speed water flow. The multiple rotating columns 105 and the rotating disk 106 are each provided with multiple flow channels 109. Several high-speed water flows can spunlace the surface of the bamboo fiber non-woven fabric, so that the bamboo in the bamboo fiber non-woven fabric is The fibers can be entangled with each other, and at the same time, the driving motor 111 of the transmission mechanism drives the driven gear 113 to rotate, and the driven gear 113 drives the driving gear 112 to rotate through the teeth, and the driving gear 112 drives a rotating column 105 fixed thereto to rotate, and the rotating column 105 drives the transmission pulley 114 on its outer side to rotate, and the transmission pulley 114 drives the adjacent transmission pulley 114 to rotate through the transmission belt 115, thereby driving the adjacent rotating column 105 to rotate, and so on, each rotating column 105 can be driven to rotate synchronously, so that the water flow ejected from the inner side of the multiple flow channels 109 is more evenly ejected at various positions of the bamboo fiber non-woven fabric, thereby improving the entanglement uniformity between the bamboo fibers therein;

[0053] Step 2: The multiple kneading mechanisms inside the spicing roller 3 and the reciprocating mechanisms therein rotate simultaneously with the spicing roller 3, the central gear 201 and the end cover 4 are fixed, and the planetary gear 210 of the reciprocating mechanism rotates around the central gear 201 while the spicing roller 3 rotates. At the same time, through the meshing of the teeth between the planetary gear 210 and the central gear 201, the planetary gear 210 will rotate on its own, thereby driving the cam shaft 208 to rotate, and the cam shaft 208 drives the cylindrical reciprocating cam 209 to rotate. When the cylindrical reciprocating cam 209 rotates, the sliding fit between the guide groove on its outer side and the sliding pin 207 is achieved. , driving the slide plate 206 of the kneading mechanism to move back and forth linearly along the outer sides of the two guide rods 203, the slide plate 206 drives the multiple fixed horizontal plates 204 fixed thereto to move back and forth linearly, each fixed horizontal plate 204 drives the multiple kneading plates 205 on one side thereof to move back and forth, each kneading plate 205 moves back and forth on the inner side of the corresponding water hole 5, and one side of each kneading plate 205 is provided with an arc surface 211 flush with the outer side of the spunlacing roller 3, so when the multiple kneading plates 205 move back and forth, the side where the bamboo fiber nonwoven fabric is attached to the spunlacing roller 3 is continuously kneaded, thereby enhancing the entanglement strength between the bamboo fibers;

[0054] Step 3: While the bamboo fiber non-woven fabric drives the two guide rollers 6 to rotate, each guide roller 6 drives the corresponding active pulley 308 of the intermittent stop mechanism to rotate, and the active pulley 308 drives the driven pulley 307 and the driven shaft 305 to rotate through the synchronous belt 309, and the driven shaft 305 drives the eccentric wheel 306 to rotate. The eccentric wheel 306 can push the brake block 304 to one side of the brake disc 301 once every rotation. At the same time, under the guidance of the slide bar 303 and the inclined groove 302, the arc groove on one side of the brake block 304 is closely attached to the outer side of the brake disc 301, and the brake disc 301 is affected by the brake block 304 and the arc groove. The pressure of the groove will stop the rotation, thereby stopping the rotation of the spicate roller 3 connected to the brake disc 301. Whenever the eccentric wheel 306 pushes the brake block 304, the brake disc 301 and the spicate roller 3 can be stopped once intermittently, so that when the bamboo fiber non-woven fabric drives the spicate roller 3 to rotate, the spicate roller 3 can be paused intermittently. Since the bamboo fiber non-woven fabric keeps moving, when the spicate roller 3 stops, the bamboo fiber non-woven fabric continues to move and slides a certain distance along the outside of the spicate roller 3, thereby continuously changing the contact position between the bamboo fiber non-woven fabric and the spicate roller 3, so that the multiple rubbing discs 205 rub different positions of the bamboo fiber non-woven fabric.

[0055] Working principle: When the bamboo fiber non-woven fabric is spunlaced, the traction motors 8 of the two traction mechanisms drive the corresponding traction rollers 9 to rotate. The four traction rollers 9 can pull the bamboo fiber non-woven fabric to move through friction. Through the guiding effect of the two guide rollers 6, the bamboo fiber non-woven fabric is wound on the upper side of the spunlaced roller 3. When the bamboo fiber non-woven fabric moves, the spunlaced roller 3 and the two guide rollers 6 can be driven to rotate through friction, thereby reducing the movement resistance of the bamboo fiber non-woven fabric.

[0056] When each position of the bamboo fiber non-woven fabric moves to the bottom of the spunlace device, the water pump 102 of the spunlace device can pump water from an external water source into the inner side of the upper chamber 103, so that the water inside the upper chamber 103 generates a certain strength of water pressure. Under the action of the water pressure, the water flows into the inner side of each flow channel 109 through the multiple water inlets 108 on the outer side of each fixed tube 107, and is ejected outward through the jet port 110 at the lower end of each flow channel 109. The diameter of the jet port 110 is smaller than the diameter of the flow channel 109, so the flow rate of the water will increase when passing through the jet port 110, so that the water can form a fine high-speed water flow. The multiple rotating columns 105 and the rotating disk 106 are each provided with multiple flow channels 109, so that several high-speed water flows can spunlace the surface of the bamboo fiber non-woven fabric, so that the bamboo fibers in the bamboo fiber non-woven fabric can be entangled with each other, thereby strengthening the structure of the bamboo fiber non-woven fabric.

[0057] At the same time, the driving motor 111 of the transmission mechanism drives the driven gear 113 to rotate, and the driven gear 113 drives the driving gear 112 to rotate through the teeth, and the driving gear 112 drives a rotating column 105 fixed thereto to rotate, and this rotating column 105 drives the transmission pulley 114 on its outer side to rotate, and this transmission pulley 114 drives the adjacent transmission pulley 114 to rotate through the transmission belt 115, thereby driving the adjacent rotating column 105 to rotate, and so on, each rotating column 105 can be driven to rotate synchronously, so that the water flow ejected from the inner side of the multiple flow channels 109 can be more evenly sprayed at various positions of the bamboo fiber non-woven fabric, thereby improving its The entanglement uniformity between the bamboo fibers in the middle part can improve the entanglement uniformity between the bamboo fibers, thereby improving the water-jet processing quality of the bamboo fiber non-woven fabric. When the upper end of the flow channel 109 is aligned with the water inlet 108, the high-pressure water inside the upper chamber 103 can flow into the inner side of the flow channel 109 and then spray out. When the upper end of the flow channel 109 is not aligned with the water inlet 108, the high-pressure water inside the upper chamber 103 will not enter the flow channel 109, so the lower end of the flow channel 109 will not spray water. As the rotating column 105 drives the multiple flow channels 109 to rotate, the water flow inside each flow channel 109 can be intermittently sprayed onto the bamboo fiber non-woven fabric, further increasing the entanglement strength of the bamboo fiber, thereby further improving the water-jet effect.

[0058] When the high-speed water flow passes through the bamboo fiber non-woven fabric, the water flow velocity is greatly reduced, and then it is discharged outward through the multiple water holes 5 on the surface of the entanglement roller 3. When the bamboo fiber non-woven fabric drives the entanglement roller 3 to rotate along the outer side of the entanglement roller 3, since the central gear 201 and the end cover 4 are fixed, the multiple kneading mechanisms inside the entanglement roller 3 and the reciprocating mechanisms therein rotate simultaneously with the entanglement roller 3. The planetary gear 210 of the reciprocating mechanism rotates around the central gear 201 while the entanglement roller 3 rotates. At the same time, through the meshing of the teeth between the planetary gear 210 and the central gear 201, the planetary gear 210 will generate self-rotation, thereby driving the cam shaft 208 to rotate, and the cam shaft 208 drives the cylindrical reciprocating cam 209 to rotate. When the cylindrical reciprocating cam 209 rotates, the sliding cooperation between the guide groove on its outer side and the sliding pin 207 can drive the kneading The slide plate 206 of the mechanism moves back and forth linearly along the outer sides of the two guide rods 203, and the slide plate 206 drives the multiple fixed horizontal plates 204 fixed thereto to move back and forth linearly, and each fixed horizontal plate 204 drives the multiple kneading plates 205 on one side thereof to move back and forth, and each kneading plate 205 can move back and forth on the inner side of the corresponding water hole 5, respectively, and one side of each kneading plate 205 is provided with an arc surface 211 flush with the outer side of the spunlacing roller 3, so when the multiple kneading plates 205 move back and forth, the side where the bamboo fiber non-woven fabric is attached to the spunlacing roller 3 can be continuously kneaded, and because the bamboo fibers in the bamboo fiber non-woven fabric are impacted to the other side by the high-speed water flow, the arc surface 211 on one side of the multiple kneading plates 205 can further enhance the entanglement strength between the bamboo fibers when kneading the bamboo fibers on the other side, thereby further improving the overall strength of the bamboo fiber non-woven fabric;

[0059] When the bamboo fiber non-woven fabric drives the two guide rollers 6 to rotate, each guide roller 6 can respectively drive the corresponding driving pulley 308 of the intermittent stop mechanism to rotate, and the driving pulley 308 drives the driven pulley 307 and the driven shaft 305 to rotate through the synchronous belt 309, and the driven shaft 305 drives the eccentric wheel 306 to rotate. The eccentric wheel 306 can push the brake block 304 to one side of the brake disc 301 once every rotation. At the same time, under the guidance of the slide bar 303 and the inclined groove 302, the arc groove on one side of the brake block 304 can be made to stick to the outer side of the brake disc 301. The brake disc 301 will stop rotating due to the pressure of the brake block 304 and the arc groove, so that the water spunlace roller 3 connected to the brake disc 301 stops When the eccentric wheel 306 pushes the brake block 304, the brake disc 301 and the spicing roller 3 can be stopped once, so that when the bamboo fiber non-woven fabric drives the spicing roller 3 to rotate, the spicing roller 3 can be stopped intermittently. Since the bamboo fiber non-woven fabric keeps moving, when the spicing roller 3 stops, the bamboo fiber non-woven fabric continues to move and slides a certain distance along the outside of the spicing roller 3, so that the contact position between the bamboo fiber non-woven fabric and the spicing roller 3 can be continuously changed, so that each position of the bamboo fiber non-woven fabric can be rubbed by multiple rubbing disks 205, thereby improving the uniformity of rubbing and making the bamboo fibers on the bamboo fiber non-woven fabric more evenly entangled, thereby further improving the overall strength of the bamboo fiber non-woven fabric.
