Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric technology, and more specifically, to an elastic nonwoven fabric and its hot rolling device. Background Technology

[0002] Nonwoven fabrics are composed of oriented or randomly arranged fibers. Nonwoven products offer advantages such as rich colors, diverse patterns and styles, lightweight, environmental friendliness, and recyclability, making them widely used in clothing, bags, wallpaper, medical supplies, and other fields. Common nonwoven fabrics are made by directly combining multiple layers of nonwoven material; therefore, existing nonwoven fabrics generally have relatively low elasticity and are easily stretched and deformed.

[0003] Currently, during the production of nonwoven fabrics, they need to be hot-rolled by hot rolling equipment. Due to the presence of lint and other impurities on the surface of the nonwoven fabric, some of them will adhere to the surface of the hot rolling roller after being bonded to it, affecting the temperature transfer of the hot rolling roller and the subsequent hot rolling effect of the nonwoven fabric. When hot rolling the next batch of nonwoven fabric, they may also adhere to the surface of the nonwoven fabric again, thus affecting the quality of the nonwoven fabric. Summary of the Invention

[0041] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0042] The following is in conjunction with the appendix Figures 1-9 This embodiment will be described in further detail.

[0043] like Figure 1 As shown, an elastic nonwoven fabric in this embodiment includes opposing nonwoven base layers 10, with an elastic layer 20 bonded between the nonwoven base layers 10, a skin-friendly layer 30 bonded to one side of the two nonwoven base layers 10, and a waterproof layer 40 bonded to the other side.

[0044] In this embodiment, the elastic layer 20 is made of elastic non-woven fabric. The elastic layer 20 provides the non-woven fabric with better elasticity.

[0045] Among them, the skin-friendly layer 30 is made of skin-friendly cotton, which improves the skin-friendly feel of the non-woven fabric.

[0046] The waterproof layer 40 is a polyethylene waterproof coating, which improves the waterproof effect of the nonwoven fabric.

[0047] This embodiment also provides a nonwoven fabric hot rolling device for hot rolling the aforementioned nonwoven fabric.

[0048] like Figure 2-9 As shown, a nonwoven fabric hot rolling device in this embodiment includes a housing 100. The housing 100 is provided with an equipment compartment 201, a processing compartment 202 and a collection compartment 203 from top to bottom. The nonwoven fabric passes through the processing compartment 202. The processing compartment 202 is provided with a first cleaning component for swinging the nonwoven fabric and a hot rolling component for hot rolling the nonwoven fabric. The hot rolling component includes opposing and rotatable hot rolling rollers 210. The processing compartment 202 is also provided with a second cleaning component for cleaning the hot rolling rollers 210.

[0049] The equipment compartment 201 is equipped with a drive component for driving the first cleaning component and the second cleaning component to work synchronously;

[0050] The bottom wall of the processing chamber 202 is provided with a feed hood 221 that connects to the collection chamber 203. The outer side wall of the box 100 is provided with an air duct 101 that connects to the collection chamber 203. The air duct 101 is used to connect to a fan (not shown in the figure) so that the debris in the processing chamber 202 can enter the collection chamber 203.

[0051] In actual use, this embodiment, such as Figure 2-4 As shown, the left and right end walls of the box 100 are provided with inlet 102 and outlet 301 corresponding to the processing chamber 202. The non-woven fabric enters the processing chamber 202 through the inlet 102, passes through the first cleaning component and the hot rolling component in sequence, and is discharged through the outlet 301. In actual use, the non-woven fabric discharged from the outlet 301 is wound up on the existing winding device.

[0052] The hot rolling roll 210 is an existing structure, which is rotatably installed in the processing chamber 202. In actual use, the non-woven fabric passes through the two hot rolling rolls 210. The hot rolling rolls 210 are preheated in advance. When the winding device pulls the non-woven fabric to wind and move, the preheated hot rolling rolls 210 rotate to perform hot rolling on the non-woven fabric.

[0053] The first cleaning component is used to swing the non-woven fabric before hot rolling, which can better shake off the lint and other impurities attached to the non-woven fabric, thus facilitating the subsequent hot rolling process of the non-woven fabric.

[0054] The second cleaning component is used to clean the impurities attached to the outer surface of the hot rolling roll 210, thereby preventing impurities from adhering to the outer surface of the hot rolling roll 210, affecting the heat transfer of the hot rolling roll 210, and causing uneven hot rolling of the nonwoven fabric.

[0055] The drive component is configured to synchronously drive the first and second cleaning components, ensuring the hot rolling effect of the hot rolling device and making the structure of the hot rolling device more compact.

[0056] In this embodiment, the fan and duct 101 are configured so that the fan can generate negative pressure in the collection chamber 203, thereby allowing impurities generated by the first cleaning component and the second cleaning component to enter the collection chamber 203 through the feed hood 221 for collection. In actual use, in order to prevent impurities from entering the fan through the duct 101, a filter screen (not shown in the figure) is provided in the duct 101.

[0057] Combination Figure 3-5 As shown, in this embodiment, the first cleaning component includes opposing mounting plates 230, with a rotating roller 231 for clamping non-woven fabric between the mounting plates 230; a fixing rod 240 is provided parallel to the width direction inside the equipment compartment 201, and a sleeve 410 is slidably sleeved on the fixing rod 240. The sleeves 410 are connected by a connecting block 411, and a driving groove 412 is provided on the connecting block 411 along the height direction of the box 100. A sliding groove 401 is provided on the bottom wall of the equipment compartment 201 along the width direction of the box 100.

[0058] The mounting plate 230 located above is provided with a through groove 401 connecting a slider to the corresponding sleeve 410. The drive assembly is used to drive the connecting block 411 to reciprocate along the fixed rod 240.

[0059] In actual use, the fixing rod 240 passes through the sleeve 410, which enables the sleeve 410 and the connecting block 411 to be installed in the equipment compartment 201. The corresponding sleeve 410 and the mounting plate 230 are connected by a slider, thereby allowing the first cleaning component to be slidably installed.

[0060] Among them, the drive component drives the connecting block 411 to slide back and forth along the fixed rod 240, which can drive the rotating roller 231 to drive the non-woven fabric to swing back and forth in the processing chamber 202, thereby causing the non-woven fabric to swing in a wave-like manner towards the hot rolling roller 210, so as to better shake off the impurities attached to it.

[0061] It should be noted that the nonwoven fabric located before the hot rolling roll 210 is in a relaxed state. Even if the nonwoven fabric swings and produces a wave-like swing, in actual use, in order to avoid the wave-like swing affecting the hot rolling roll 210's hot rolling of the nonwoven fabric, a rotatable clamping roll 290 is provided in the processing chamber 202 and located in front of the hot rolling roll 210. The clamping roll 290 is an existing structure. It rotates in conjunction with the winding device, which can make the nonwoven fabric pass through the hot rolling roll 210 more smoothly and make it undergo hot rolling treatment.

[0062] Of course, in this embodiment, in order to enable maintenance and replacement of the contents of the box 100, a detachable side panel is provided on one side wall of the box 100, thereby better realizing the opening and closing of the equipment compartment 201, the processing compartment 202 and the collection compartment 203, which facilitates actual use.

[0063] Combination Figure 5-6 As shown, in this embodiment, swing rods 250 are hinged to each other on the bottom wall of the equipment compartment 201 and located on both sides of the sleeve 410. One end of the swing rod 250 extends to one end of the slide groove 401, and the other end of the swing rod 250 is provided with a stop bar 251 extending into the processing compartment 202. The bottom wall of the equipment compartment 201 is provided with a tension spring 420 for pulling the swing rod 250 to move the stop bar 251 away from the nonwoven fabric. The sleeve 410 reciprocates to drive one end of the corresponding swing rod 250 to make the stop bar 251 approach the nonwoven fabric.

[0064] In actual use, the swing rod 250 is bent, and its bent part is rotatably mounted on the bottom wall of the equipment compartment 201 via a hinge shaft. The bottom wall of the equipment compartment 201 is provided with a limiting groove 431 coaxially with the bending point of the swing rod 250. The stop rod 251 extends into the processing compartment 202 through the corresponding limiting groove 431. The tension spring 420 is used to pull the other end of the corresponding swing rod 250, so that the swing rod 250 rotates around the bending point and moves the stop rod 251 away from the non-woven fabric. Even if the stop rod 251 is away from the non-woven fabric in the initial state, it will prevent the non-woven fabric from oscillating in a wave-like manner and affecting the shaking off of impurities on the non-woven fabric.

[0065] With the structure in this embodiment, when the lower sleeve 410 moves toward the corresponding swing rod 250, it can squeeze one end of the swing rod 250, causing the swing rod 250 to rotate around the bending point, driving the stop rod 251 to move along the limiting groove 431, so that the stop rod 251 can approach the non-woven fabric, thereby enabling it to beat the wavy non-woven fabric, thus improving the effect of shaking off impurities. Thus, the reciprocating sliding of the sleeve 410 on the fixed rod 240 can periodically drive the corresponding swing rod 250 to beat the wavy non-woven fabric, thereby improving the cleaning effect of the first cleaning component on the non-woven fabric.

[0066] In this embodiment, the drive assembly includes a dual-axis motor 260 disposed on the bottom wall of the equipment compartment 201. One end of the output shaft of the dual-axis motor 260 is provided with a turntable 510. The turntable 510 is provided with a drive column 511 extending into the drive groove 412 on the side facing the connecting block 411 and at the edge.

[0067] With the structure in this embodiment, the dual-axis motor 260 can start to drive the turntable 510 to rotate, and the drive column 511 can slide along the drive groove 412 to enable the connecting block 411 to move back and forth along the fixed rod 240, thereby better driving the first cleaning component to work.

[0068] Combination Figure 6-7 As shown, in this embodiment, the second cleaning component includes a rotatable shaft 270, the upper end of which extends into the equipment compartment 201. A brush cylinder 271 is sleeved on the shaft 270, and the outer wall of the brush cylinder 271 is provided with bristles for brushing the hot rolling roller 210. The driving component is used to drive the shaft 270 to rotate and drive the brush cylinder 271 to rotate, so that the bristles brush the outer surface of the hot rolling roller 210.

[0069] In actual use, the rotating shaft 270 is arranged along the axial direction of the hot rolling roll 210 on one side of the hot rolling roll 210. The bottom wall of the processing chamber 202 is provided with a through hole corresponding to the rotating shaft 270, which connects to the collection chamber 203. The through hole allows impurities generated by the second cleaning component to enter the collection chamber 203 for collection.

[0070] The through hole is fitted with a bracket 540. The lower end of the rotating shaft 270 is rotatably mounted on the corresponding bracket 540 via a bearing. The upper end of the rotating shaft 270 extends into the equipment compartment 201 and is rotatably mounted on the top wall of the equipment compartment 201 via a bearing. Thus, the rotating installation of the rotating shaft 270 is preferably achieved.

[0071] In actual use, the brush cylinder 271 is sleeved on the outside of the rotating shaft 270, and the two are connected by a keyway. That is, the rotation of the rotating shaft 270 can drive the brush cylinder 271 to rotate, thereby better driving the bristles to brush the surface of the hot rolling roll 210, so that the impurities attached to the surface of the hot rolling roll 210 can be brushed and cleaned.

[0072] In this embodiment, in order to drive the rotating shaft 270 to rotate, a mating box 520 is provided on the bottom wall of the equipment compartment 201. The other end of the output shaft of the dual-axis motor 260 extends into the mating box 520. The other end of the output shaft of the dual-axis motor 260 is provided with a main bevel gear. The mating box 520 is provided with a transmission rod 521 whose two ends extend to the corresponding rotating shaft 270. The transmission rod 521 located in the mating box 520 is provided with a secondary bevel gear 522 that mates with the main bevel gear. The upper end of the rotating shaft 270 is provided with a worm gear 531. The two ends of the transmission rod 521 are provided with worms 523 that mate with the corresponding worm gears 531.

[0073] In this embodiment, the transmission rod 521 is rotatably mounted in the mating box 520 via bearings. Through the above-described structure, when the dual-shaft motor 260 rotates, the main bevel gear and the secondary bevel gear 522 can drive the rotation of the transmission rod 521. Through the cooperation of the worm gear 531 and the worm 523, the rotation of the transmission rod 521 can drive the two rotating shafts 270 to rotate synchronously, so as to realize the brush bristles to clean the surface of the hot rolling roll 210.

[0074] In this embodiment, the upper end of the brush cylinder 271 is provided with a connecting cylinder 610 extending into the equipment compartment 201. The upper end of the connecting cylinder 610 is rotatably mounted on a lifting ring 620. The equipment compartment 201 is provided with a vibration component for driving the lifting ring 620 to move up and down.

[0075] In actual use, the bottom wall of the equipment compartment 201 is provided with a guide rod (not shown in the figure) that passes through the lifting ring 620. This restricts the lifting ring 620 so that it can rise and fall along the guide rod. This better ensures the fit between the subsequent vibrating slide column 621 and the vibrating slide groove. At this time, the connecting cylinder 610 is rotatably installed in the lifting ring 620 through the bearing, so that the rotation of the rotating shaft 270 can drive the brush cylinder 271 to rotate.

[0076] The vibration component drives the brush cylinder 271 to vibrate, causing impurities attached to the brush bristles to fall off and preferably fall into the collection chamber 203 through the through hole, thus ensuring the cleaning effect of the brush bristles on the hot roller 210.

[0077] In this embodiment, a first spring 630 is sleeved on the rotating shaft 270 located below the worm gear 531 to push the lifting ring 620 against the bottom wall of the equipment compartment 201. The vibration assembly includes a vibration frame 280 that can reciprocate along the width direction of the housing 100 and covers the corresponding lifting ring 620. A vibration groove is provided on the opposite side wall of the vibration frame 280. A retractable vibration slide column 621 is provided on the side wall of the lifting ring 620 and extends into the corresponding vibration groove. The reciprocating movement of the vibration frame 280 is used to drive the vibration slide column 621 to slide back and forth along the vibration groove, thereby realizing the lifting and lowering vibration of the lifting ring 620.

[0078] In this embodiment, as Figure 9As shown, the vibration frame 280 includes interlocking half-frame plates 710. A vibration chute is disposed on the opposite sides of the half-frame plates 710. The vibration chute includes a horizontal groove 711 and a vertical groove 712 intersecting at one end. The horizontal groove 711 and the vertical groove 712 are perpendicular to each other. The other ends of the horizontal groove 711 and the vertical groove 712 are connected by an inclined groove 713. The bottom wall of the horizontal groove 711 is an inclined guide surface. The lowest point of the guide surface is connected to the vertical groove 712, and there is a height difference between the highest point of the guide surface and the inclined groove 713. Therefore, in the initial state, the vibration slide column 621 is located at the lowest point of the inclined groove 713. Due to the height difference between it and the horizontal groove 711, the vibration frames 280 move away from each other, allowing the vibration slide column 621 to move along the inclined groove 713. The movement causes the lifting ring 620 to move upward, which in turn drives the brush cylinder 271 to move upward. When the vibration frame 280 moves and the vibration slide column 621 slides from the inclined groove 713 into the vertical groove 712, the first spring 630 drives the lifting ring 620 to move downward, causing it to hit the bottom wall of the equipment compartment 201, thereby causing the brush cylinder 271 to vibrate. In actual use, the vertical groove 712 has a certain width, which can meet the movement of the vibration frame 280 to the farthest point. At this time, the vibration slide column 621 moves to the lowest end of the vertical groove 712 under the action of the first spring 630. At this time, the vibration frame 280 resets so that the vibration slide column 621 can slide along the guide surface on the bottom wall of the horizontal groove 711 to the lowest end of the inclined groove 713, so that the vibration frame 280 can move again to drive the brush cylinder 271 to vibrate.

[0079] In order to enable the vibratory slide column 621 to slide and reset along the guide surface, the vibratory slide column 621 is telescopically oriented. In actual use, for example... Figure 9 As shown, the vibrating slide column 621 includes a fixed column 810 connected to the lifting ring 620. The fixed column 810 has an outwardly opening sliding cavity 811. A sliding column 820 with one end protruding is provided in the sliding cavity 811 through a second spring. A limiting groove 821 is provided on the outer wall of the sliding column 820 along its axial direction. A retaining ring 830 is provided at the opening of the sliding cavity 811. A limiting slider 831 that extends into the limiting groove 821 and slides is provided on the retaining ring 830. Thus, the telescopic setting of the vibrating slide column 621 is preferably realized.

[0080] In this embodiment, extension blocks 413 are provided on both sides of the connecting block 411, and a connecting plate 281 connecting the corresponding vibration frame 280 is provided on the extension block 413.

[0081] With the above-described structure, the connecting plate 281 is connected to the extension block 413, so that the drive component can drive the connecting block 411 to vibrate the brush cylinders 271 on both sides at intervals during the reciprocating movement, so that the first cleaning component can oscillate the non-woven fabric in a wave-like manner, and at the same time, it can make the brush cylinders 271 vibrate at intervals, thereby making the hot rolling device have a better hot rolling effect on the non-woven fabric.

[0082] In actual use, in order to ensure that the vibration frame 280 is stably slidably installed on the bottom wall of the equipment compartment 201, a T-shaped groove (not shown in the figure) is provided on the bottom wall of the equipment compartment 201 along the moving direction of the vibration frame 280, and a T-shaped slider (not shown in the figure) is provided on the bottom wall of the vibration frame 280, which slides in the T-shaped groove.

[0083] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.
