Description

Technical Field

[0001] This utility model relates to the field of static electricity elimination technology, and in particular to a static electricity elimination device for non-woven fabric production. Background Technology

[0002] Nonwoven fabric production is a process that directly processes natural or chemical fibers into fabric through physical means without going through the spinning and weaving process. After the raw fiber is treated, it is opened and combed into a uniform fiber web. The polymer is melted, extruded, spun, and stretched into a web. Then it is thermally bonded and shaped, and finally cut and wound to obtain the finished product.

[0003] During the hot rolling bonding process, the fiber web rubs against the rollers during web fixing and charges transfer during separation. The large accumulation of static electricity can cause the finished fabric to stick to the rollers and curl at the edges. It is necessary to use an ion bar to generate an ion airflow to neutralize the static electricity on the surface of the fiber web.

[0004] In existing technologies, some static elimination devices used in nonwoven fabric production are unable to meet the hot rolling bonding requirements of fiber fabrics of different thicknesses during the nonwoven fabric production process. The fiber web is prone to sticking to the hot rolling roller, causing scorch marks on the surface of the fiber fabric, resulting in material jamming and fiber fabric breakage. This leads to uneven distribution of bonding points and curling of the fabric surface after hot rolling, affecting the flatness and strength of the finished product. Therefore, a static elimination device for nonwoven fabric production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an electrostatic elimination device for nonwoven fabric production, which aims to improve the existing technology where the fiber web easily sticks to the hot rolling roller, causing scorch spots on the surface of the fiber fabric, resulting in material jamming and fiber fabric breakage, and leading to uneven distribution of fabric edges and bonding points after hot rolling.

[0007] This utility model has the following beneficial effects: 1.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example: A static electricity elimination device for nonwoven fabric production, as described in the following reference. Figure 1 , Figures 2 to 4The system includes a housing 1, which is a rectangular box made of aluminum alloy. The housing 1 provides the mounting base and also serves as a protective and electromagnetic shield. A conveyor belt 2 is detachably connected to the left side of the housing 1 via bolt assembly. The conveyor belt 2 can transport the fiber web to be processed into the housing 1 for hot rolling and bonding. A fan 3 is fixedly connected to the top inner wall of the housing 1. The fan 3 can cool the molten fiber web being bonded and also assist in dust removal. A discharge port 4 is fixedly connected to the bottom inner wall of the housing 1. An inclined stainless steel discharge port 4 is welded to the bottom inner wall of the housing 1. The smooth surface of the discharge port 4 can ensure that the processed fiber web is output without damage. Multiple thickness adjustment mechanisms 5 are fixedly connected to the front side of the housing 1. An electrostatic elimination mechanism 6 is rotatably connected inside the housing 1. A hot rolling bonding mechanism 7 is fixedly connected to the rear side of the housing 1. The thickness adjustment mechanism 5 includes a motor 51, the rear of which is fixedly connected to the front of the housing 1. The motor 51 is fixed to the front mounting position of the housing 1 by motor seat bolts. The motor 51 can achieve precise angle control to meet the bonding requirements of fiber web layers of different thicknesses. A guide plate 52 is fixedly connected to the drive end of the motor 51. The guide plate 52 has guiding and limiting functions and can rotate and adjust with the motor 51. One of the track plates 53 is rotatably connected inside the housing 1. The track plate 53 is rotatably connected to the inner wall of the housing 1 by a rotating shaft. Multiple rollers 54 are slidably connected inside the track plate 53. The track plate 53 has grooves and multiple fiber rollers 54 are slidably connected inside. The spacing between the rollers 54 can be adjusted to adapt to different bonding thicknesses of the fiber web layer. Multiple linkage components 55 are fixedly connected inside the multiple rollers 54. The linkage assembly 55 includes multiple limiting posts 551, which are externally fixedly connected to the inside of the roller block 54. The limiting posts 551 are made of hard alloy and have a limiting function to control the movement trajectory of the roller block 54. The guide plate 52 has eight arc-shaped guide grooves 552 inside, which can realize the opening and closing of the eight roller blocks 54. Specifically, when the nonwoven fabric production device is producing fiber fabrics of different thicknesses, the motor 51 is first started to adjust the preset thickness. The drive end of the motor 51 drives the guide plate 52 to rotate synchronously. Since the limiting post 551 is embedded in the arc-shaped guide groove 552 of the guide plate 52, the rotation of the guide plate 52 will generate a thrust on the limiting post 551 along the groove. The limiting post 551 then drives the roller block 54 fixed thereto to slide in a straight line in the groove of the track plate 53. Multiple roller blocks 54 unfold under the limiting action of the guide groove 552, so that the roller blocks 54 can continuously apply pressure to the lower surface of the fiber fabric.

[0013] Reference Figure 2 and Figure 5The static elimination mechanism 6 includes two ion air bars 61. The two ion air bars 61 are externally rotatably connected to the inside of the housing 1. The two copper ion air bars 61 are rotatably connected to the inner walls of the two sides of the housing 1 through bearings. They can generate ion airflow to neutralize the static electricity on the surface of the fiber web, thereby achieving the effect of static elimination. Cleaning brushes 62 are fixedly connected to the opposite side of the two ion air bars 61. The carbon fiber cleaning brushes 62 are embedded in the opposite end of the two ion air bars 61 by screws and are used to remove deposits on the fiber surface. A transmission component 63 is fixedly connected to the front side of the ion air bars 61. The transmission component 63 includes a gear 631, the rear of which is fixedly connected to the front of the ion air bar 61. The gear 631 is welded to the front of the ion air bar 61 and can drive the ion air bar 61 to rotate up and down, realizing the integration of static electricity elimination and dust removal on the fiber web surface. The front of the housing 1 is fixedly connected to a track block 632, which is made of aluminum alloy and has a dovetail groove on the front as a sliding support. The front of the track block 632 is slidably connected to a rack 633, which can slide in the dovetail groove of the track block 632. The rack 633 is matched with the tooth profile of the gear 631. The right side of the rack 633 is fixedly connected to a handle 634, which is an operating component that is easy to adjust manually. It is fixed to the end of the rack 633 and can adjust the angle of the ion air bar 61 by pulling the handle 634. When producing fiber cloth of different thicknesses, the operator can pull the handle 634 to drive the rack 633 to slide, quickly adapting to changes in fiber cloth thickness. Specifically, when the thickness of the bonded fiber cloth changes, the coverage area of ​​the ion air bar 61 needs to be adjusted. The operator pulls the handle 634, and the rack 633 slides in the dovetail groove of the track block 632 under the pulling force. The tooth surfaces on both sides of the rack 633 mesh with the upper and lower gears 631, driving the two gears 631 to rotate synchronously in opposite directions. The gears 631 then drive the ion air bar 61 welded to it to rotate up and down around the bearing as the axis. When the fiber web thickens, the two ion air bars 61 rotate outward to widen the included angle to adapt to the width of the fabric surface, ensuring that the ion air accurately covers the front and back of the fabric surface. During the static removal process, the cleaning brush 62 on the ion air bar 61 rotates with the air bar, sweeping across the surface of the fiber cloth to remove the dust and broken fibers adsorbed by static electricity, realizing simultaneous static removal and dust removal.

[0014] Reference Figures 3 to 5The hot-rolled bonding mechanism 7 includes a second motor 71, the front side of which is fixedly connected to the rear side of the housing 1. The variable frequency motor 71 is fixedly connected to the rear side of the housing 1 through a bracket. The drive end of the second motor 71 is fixedly connected to a second gear 72, which can drive the second gear 72 to rotate. The rear inner wall of the housing 1 is fixedly rotatably connected to a third gear 73. The third gear 73 and the second gear 72 are paired transmission components that transmit the power of the second motor 71. They have the same module. The front side of the second gear 72 is fixedly connected to a steel roller 74. The steel roller 74 is a chrome-plated engraved alloy roller with a heating tube embedded inside. It is the key to the hot-rolled bonding process. The engraved pattern on the surface bonds the fiber web dots. The partial area of ​​the hot-rolled fiber web is bonded and reinforced, while the unbonded area retains the original fluffiness of the fiber web. The limiting post 551 is externally slidably connected to the inside of the guide groove 552. Rotation of the guide plate 52 causes the limiting post 551 to slide within the guide groove 552, allowing the roller block 54 to slide within the groove of the track plate 53. This controls the opening and closing of the roller block 54, thereby changing the distance between the steel roller 74 and the roller block 54, meeting the bonding requirements of fiber web layers of different thicknesses. The rear side of another track plate 53 is fixedly connected to the front side of the third gear 73. The other track plate 53 and the third gear 73 are connected by a spline. The outside of the rack 633 meshes with the outside of the two first gears 631. Sliding of the rack 633 can drive the two gears... 631 rotates synchronously in opposite directions. The handle 634 is externally slidably connected to the inside of the housing 1. The handle 634 is covered with an anti-slip rubber sleeve and is slidably connected in the hole of the housing 1, which can limit the adjustment stroke of the rack 633. The external of the gear 72 of the second gear is meshed with the external of the gear 73 of the third gear. The gear 72 and the gear 73 rotate synchronously in opposite directions. The external of the steel roller 74 is rotatably connected to the front inner wall of the housing 1. The steel roller 74 and the roller block 54 can pull the fiber web. The fiber web layer passes through the roller jaws. Some fibers in the fiber web melt under the action of heating of the steel roller 74 and pressure of the roller block 54. The multi-layer fiber web forms a good bond. Specifically, after the device is started, the conveyor belt 2 feeds the fiber web to be processed into the housing 1 at a uniform speed. First, the thickness adjustment mechanism 5 pre-adjusts according to the thickness of the fiber web: motor 1 51 drives the roller block 54 to open and close to the appropriate spacing, providing stable support for the fiber web. At the same time, the operator adjusts the ion air bar 61 to the appropriate angle through the handle 634 to activate the ion air removal in advance. Subsequently, the multi-layer fiber web moves towards the hot rolling area under the traction of the roller block 54. Motor 2 71 starts and drives gear 2 72 to rotate. Gear 2 72 meshes with gear 3 73 to drive the upper and lower rollers to rotate synchronously in opposite directions. The heating tube inside the steel roller 74 heats up to the set temperature. The chrome-plated engraved surface cooperates with the roller block 54 to form uniform pressure on the fiber web. When the multi-layer fiber web passes through the roller jaws, some fibers melt at high temperature. The engraved pattern achieves point bonding, which ensures that the multi-layer fiber web is firmly bonded while retaining the fluffiness of the unbonded areas. The bonded fiber web continues to move forward and is collected through the discharge port 4.

[0015] The implementation principle of this application embodiment is as follows: In the nonwoven fabric production process, when facing the hot rolling bonding of fiber fabrics of different thicknesses, it is necessary to first adjust the distance between the roller jaws to the preset thickness using the thickness adjustment mechanism 5. The operator starts the motor 51 to drive the guide plate 52 to rotate synchronously. Since the limiting post 551 is embedded in the arc-shaped guide groove 552 of the guide plate 52, the rotation of the guide plate 52 will generate a thrust on the limiting post 551 along the groove. The limiting post 551 then drives the roller block 54 fixed thereto to slide linearly in the groove of the track plate 53. Multiple roller blocks 54 are linked by the linkage assembly 5. Under the limiting action of 5, the fiber web unfolds, and then the heating tube inside the steel roller 74 heats up to the set temperature. The conveyor belt 2 transports multiple fiber webs. The motor 2 71 starts and drives the gear 2 72 to rotate. The gear 2 72 meshes with the gear 3 73 to drive the upper and lower rollers to rotate synchronously in opposite directions to pull the fiber webs. The surface of the steel roller 74 is engraved and cooperates with the roller block 54 to form uniform pressure on the fiber web layer. When the multi-layer fiber web passes through the roller jaws, some fibers melt and bond under the high temperature of the hot rolling bonding mechanism 7. After being cooled by the fan 3, it undergoes electrostatic removal and dust removal operations, and finally the fiber cloth is collected through the discharge port 4.

[0016] When the thickness of the bonded fiber cloth changes, the coverage area of ​​the ion air bar 61 needs to be adjusted. The operator pulls the handle 634 on the outside of the housing 1, and the rack 633 slides in the dovetail groove of the track block 632 under the pulling force. The tooth surfaces on both sides of the rack 633 mesh with the upper and lower gears 631, driving the two gears 631 to rotate synchronously in opposite directions. The gears 631 then drive the ion air bar 61 welded to it to rotate up and down around the bearing. When the fiber web thickens, the transmission component 63 can expand the angle between the two ion air bars 61 to adapt to the width of the fabric surface, ensuring that the ion air covers both sides of the fabric surface. During the static elimination process, the cleaning brush 62 on the ion air bar 61 rotates with the air bar and sweeps across the surface of the fiber cloth to remove the dust and broken fibers adsorbed by static electricity. The static elimination mechanism 6 realizes the simultaneous operation of static elimination and dust removal.
