Abstract
Description
Technical Field
[0001] This invention relates to the field of static electricity elimination technology, specifically to a static electricity elimination device for carpet processing. Background Technology
[0002] In carpet production and processing, static electricity elimination is a crucial step in ensuring safety, improving efficiency, and enhancing product quality. Static electricity buildup caused by friction between carpet raw materials (such as synthetic fibers and rubber) and equipment can trigger spark discharges. In environments containing dust or flammable gases, static sparks can ignite combustibles, leading to fires or explosions. Simultaneously, static electricity can also cause fiber entanglement and yarn loosening, resulting in process defects such as yarn breakage and increased fuzziness during spinning and weaving.
[0003] Existing technologies for static electricity elimination in carpet processing include grounding with conductive metal or using an electrostatic gun for static neutralization. However, when using grounding with conductive metal on thicker carpets, the bottom layer of the carpet pile may not adhere directly to the conductive metal, resulting in poor static electricity elimination and the creation of dead zones. Electrostatic guns, on the other hand, have limited airflow coverage (typically tens of centimeters to several meters in diameter), making it difficult to evenly treat large areas. Regular cleaning of the discharge needle and nozzle is also necessary. If the discharge needle is too far from the carpet, a large amount of charged air diffuses outwards, rendering it unusable and reducing efficiency, thus increasing energy consumption costs. Conversely, if the discharge needle is too close to the carpet, continuous contact between the moving carpet and the needle increases the probability of damage. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the present invention aims to provide an electrostatic elimination device for carpet processing, thereby solving the problems mentioned in the background art. The present invention utilizes a surface electrostatic elimination mechanism and an inner electrostatic elimination mechanism working together to control the intermittent movement of the carpet. The surface electrostatic elimination mechanism eliminates static electricity in the pressed areas of the carpet surface, while the inner electrostatic elimination mechanism neutralizes static electricity in dead-angle areas, ensuring the elimination of static dead-angles. Furthermore, the discharge needle can be activated intermittently, significantly reducing the space where charged air masses can diffuse, improving the utilization rate of charged air masses, reducing energy consumption costs, and enabling close-range dust removal of the carpet area after electrostatic elimination on the inner side.

The compressed air pump has a built-in filter structure. Two pressing wheels are installed at the bottom of the surface static electricity elimination mechanism, and the bottom of each pressing wheel presses against the surface of the carpet.
[0006] Furthermore, the drive mechanism includes a motor and a driven shaft. An end plate is integrally formed on one end of the surface of the base plate. The motor is screwed to the outer side of the end plate. A support frame is welded to the top of the outer frame. The driven shaft is inserted into the inner side of the support frame. A cam is keyed to the surface of the driven shaft. A conductive sheet is embedded at the end of the cam.
[0007] Furthermore, a drive shaft is inserted into the output end of the motor, and the surface of the drive shaft is inserted into the interior of the end plate through a bearing. A transmission box is welded to the rear end of the end plate, and a gear and belt drive assembly is installed inside the transmission box. The end of the drive shaft transmits torque to the driven shaft through the transmission box.
[0008] Furthermore, there are two cams, and the cams abut against the top of the inner antistatic mechanism below through rotational movement. Both ends of the driven shaft are embedded into the support frame through bearings.
[0009] Furthermore, the surface static elimination mechanism includes an outer frame, pressing wheels, and end baffles. Dust removal channels are provided inside both sides of the outer frame. Connecting frames are welded to both ends of the outer frame. End baffles are fitted at the bottom of the connecting frames. The bottom of the end baffles is welded and fixed to the side of the base plate.
[0010] Furthermore, the end baffle has a notch at the top and a plug plate is provided on the inner side of the end baffle. The connecting bracket extends downward from the notch into the inner side of the end baffle, and the inner side of the plug plate is embedded into the inside of the pressing wheel by a rod.
[0011] Furthermore, a dust removal gap is provided between the bottom of the outer frame and the pressing wheel, and an air extraction hole is installed at the bottom of the outer frame. The air extraction hole is connected to the interior of the dust removal channel, and the dust removal channel is partially connected to the air supply pipe.
[0012] Furthermore, the inner static elimination mechanism includes a lifting plate, a first enclosure plate, a second enclosure plate, and a discharge needle. The top of the lifting plate is integrally formed with a top plate, and one side of the top plate is integrally formed with a pressure plate. A conductive sleeve is provided on the top of the lifting plate, and clamping grooves are provided at both ends of the conductive sleeve.
[0013] Furthermore, a conductive wire is inserted inside the conductive sleeve, and the cam is embedded into the inside of the clamping groove after rotation.

The surface static elimination mechanism eliminates static electricity in the pressed areas of the carpet surface, and the inner static elimination mechanism neutralizes static electricity in the dead corner areas, ensuring the elimination of static dead corners and making static elimination more thorough.
[0016] The discharge needle of the static elimination device for carpet processing can be activated intermittently, which greatly reduces the space in which charged air masses can diffuse. This ensures that the charged air masses can pass through the gap between the bottom of the pressing roller and the area in contact with the carpet, preventing a large amount of air masses from being discharged from the dust removal gap at the top of the pressing roller. This improves the utilization rate of charged air masses and reduces energy consumption costs.

It can also perform filtration with the filter structure built into the compressed air pump. The drive system can also automatically control whether the inner static electricity elimination mechanism performs discharge treatment through the discharge needle through the transmission structure. It has a high degree of automation, reduces equipment control costs, and the discharge needle can also avoid scratching the carpet surface when it is moving. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0020] Please see Figures 1 to 7The present invention provides the following technical solution: a static electricity elimination device for carpet processing, comprising a static electricity elimination device body, the static electricity elimination device body comprising a base plate 1, a driving mechanism 2, and a static electricity neutralization component 3, wherein the driving mechanism 2 is mounted on one end of the base plate 1, the carpet is laid and pressed on the surface of the base plate 1, one end of the carpet is connected to a roll-up guide roller, and the other end of the carpet is wound around the driving mechanism 2, the static electricity neutralization component 3 comprising a surface static electricity elimination mechanism 4 and an inner static electricity elimination mechanism 5, wherein an outer layer is welded to the outside of the surface static electricity elimination mechanism 4. The outer frame 9 has a compressed air pump 6 screwed to its top. One end of the compressed air pump 6 is connected to an air extraction pipe 8, and the other end is connected to an air delivery pipe 7. The end of the air delivery pipe 7 is connected to the interior of the inner layer antistatic mechanism 5. The air extraction pipe 8 is connected to the interior of the outer frame 9, and the compressed air pump 6 has a built-in filter structure. Two pressing wheels 31 are installed at the bottom of the surface antistatic mechanism 4, with the bottom of each wheel pressing against the carpet surface. This antistatic device is used to neutralize or discharge static electricity generated during carpet production.
[0021] In use, one end of the carpet is wound around the drive shaft 16 of the drive mechanism 2. The drive mechanism 2 rolls the carpet, allowing it to move. Simultaneously, the transmission structure at the rear controls the synchronous rotation of the top cam 12. During the cyclic rotation of the cam 12, it intermittently abuts against the top of the inner antistatic structure. During this process, as the bottom carpet moves, it comes into contact with the bottom pressing wheel 31 of the surface antistatic mechanism 4. Through direct contact, the static electricity on the carpet surface in contact with the pressing wheel 31 is grounded and discharged. Simultaneously, through… The aforementioned pushing effect on the inner layer antistatic mechanism 5 enables it to perform intermittent lifting and lowering movements. At the moment it reaches the lowest point, it automatically triggers the internal discharge needle 29 to generate voltage. The high voltage at the tip of the discharge needle 29 ionizes the air to generate ion wind. The air is ionized into positive and negative ions. In conjunction with the external compressed air pump 6, the generated airflow ejects the ion wind, which produces air masses with positive and negative charges. When the carpet surface carries a negative charge, it attracts the positive charge in the air mass; when the carpet surface carries a positive charge, it attracts the negative charge in the air mass, thereby neutralizing the static electricity on the carpet surface.
[0022] In this embodiment, the drive mechanism 2 includes a motor 15 and a driven shaft 11. An end plate 14 is integrally formed on one end of the surface of the base plate 1. The motor 15 is screwed onto the outer side of the end plate 14. A support frame 10 is welded to the top of the outer frame 9. The driven shaft 11 is inserted into the inner side of the support frame 10. A cam 12 is keyed to the surface of the driven shaft 11, and a conductive sheet 13 is embedded at the end of the cam 12. A drive shaft 16 is inserted into the output end of the motor 15. The surface of the drive shaft 16 is inserted into the interior of the end plate 14 via a bearing. A transmission box 17 is welded to the rear end of the end plate 14, and a gear and belt drive assembly is installed inside the transmission box 17. The end of the drive shaft 16 transmits torque to the driven shaft 11 through the transmission box 17. There are two cams 12, and the cams 12 rotate and abut against the top of the inner antistatic mechanism 5 below. Both ends of the driven shaft 11 are embedded into the interior of the support frame 10 via bearings. By enabling close-range dust removal of the carpet area after static electricity elimination on the inner side, the utilization of airflow is further improved. The filter structure built into the compressed air pump 6 can also be used for filtration. The drive system can also automatically control whether the inner static electricity elimination mechanism 5 is discharged through the discharge needle 29 through the transmission structure. The degree of automation is high, which reduces the equipment control cost. In addition, the discharge needle 29 can also avoid scratching the carpet surface in the moving state.
[0023] Specifically, after starting the motor 15, the drive shaft 16 is rotated by the motor 15. Since one end of the carpet is directly wound around the surface of the drive shaft 16, starting the motor 15 will directly drive the carpet to roll up. At the same time, through the transmission box 17 at the rear end and the internal transmission structure, the driven shaft 11 at the top of the static neutralization component 3 can be controlled to rotate synchronously. The driven shaft 11 will drive the cam 12 on the surface to rotate. The inner side of the protruding area at the end of the cam 12 is fitted with a conductive sheet 13. When the cam 12 rotates to the bottom direction, it will abut against the surface of the extension plate and the top plate 19, causing the entire inner static elimination mechanism 5 to move downward. Therefore, the bottom of the inner static elimination mechanism 5 can be controlled to be close to the surface of the carpet. At the same time, the circuit of the discharge needle 29 is conducted by means of the conductive structure, so as to generate high voltage ionization of air at the tip of the discharge needle 29 and thus generate ion wind. The transmission box 17 and the internal gear and belt drive structure are existing mature technologies and are not within the protection scope of this invention. Therefore, the structure and principle of the transmission box 17 and its internal structure will not be described in detail here.
[0024] In this embodiment, the surface static elimination mechanism 4 includes an outer frame 9, a pressing wheel 31, and an end baffle 33. Dust removal channels 37 are formed inside both sides of the outer frame 9. Connecting frames 36 are welded to both ends of the outer frame 9, and the end baffle 33 is fitted onto the bottom of the connecting frame 36. The bottom of the end baffle 33 is welded and fixed to the side of the base plate 1. A notch 35 is formed at the top of the end baffle 33, and a plug-in plate 34 is provided on the inner side of the end baffle 33. The connecting frame 36 extends downwards from the notch 35 into the inner side of the end baffle 33. The inner side of the plug-in plate 34 is embedded into the interior of the pressing wheel 31 via a rod. A dust removal gap 32 is provided between the bottom of the outer frame 9 and the pressing wheel 31, and an air extraction hole 30 is installed at the bottom end of the outer frame 9. The air extraction hole 30 is connected to the interior of the dust removal channel 37, and the dust removal channel 37 is partially connected to the air supply pipe 7. By cooperating with the surface antistatic mechanism 4 and the inner antistatic mechanism 5, the carpet is controlled to move intermittently. The surface antistatic mechanism 4 eliminates static electricity in the pressed areas of the carpet surface, and the inner antistatic mechanism 5 neutralizes static electricity in the dead corner areas, ensuring the elimination of static dead corners and making the elimination of static electricity more thorough.
[0025] Specifically, the surface static elimination mechanism 4 directly contacts the carpet surface below through the bottom pressing roller 31. The area where the carpet surface directly contacts the bottom of the pressing roller 31 can conduct static charge through the pressing roller 31, achieving the static elimination effect on the surface contact area. Because the carpet surface is covered with a large amount of pile, the pressing roller 31 cannot directly contact the bottom of the pile and the carpet backing area due to the obstruction of the pile. In addition, a large number of tiny gaps are also generated at the bottom of the pressing roller 31. These gaps are used to provide airflow for the subsequent inner static elimination mechanism 5 to be discharged when it is activated. Throughout the dust removal process, the compressed air pump 6 will continuously draw airflow from the air extraction hole 30 area. This airflow will assist in the extraction of dust on the carpet area on both sides of the pressing roller 31, achieving the purpose of dust removal.
[0026] In this embodiment, the inner static elimination mechanism 5 includes a lifting plate 18, a first surrounding plate 25, a second surrounding plate 26, and a discharge needle 29. The top of the lifting plate 18 is integrally formed with a top plate 19, and a pressure plate 20 is integrally formed on one side of the top plate 19. A conductive sleeve 21 is provided on the top of the lifting plate 18, and clamping grooves 22 are formed at both ends of the conductive sleeve 21. A conductive wire 23 is inserted inside the conductive sleeve 21. The cam 12 is inserted into the clamping groove 22 after rotation. The conductive sheet 13 is used to fit against the conductive wire 23 on the inner wall of the clamping groove 22. Diversion channels 24 are welded to both sides of the bottom of the lifting plate 18. A second surrounding plate 26 is installed on the outer side of the diversion channels 24, and a first surrounding plate 25 is welded to both ends of the second surrounding plate 26. A sealing gasket 27 is affixed to the bottom side of the second enclosure 26. After being lowered, the sealing gasket 27 rests against the surface of the pressing roller 31. A return spring 38 is inserted into the top of the second enclosure 26, and the top of the return spring 38 is connected to the inner wall of the outer frame 9. The lifting plate 18 passes through the top of the outer frame 9. An air jet vent 28 is installed at the bottom of the diversion channel 24, and a discharge needle 29 is inserted into the bottom of the lifting plate 18. The discharge needle 29 can be activated intermittently, significantly reducing the space where charged air masses can diffuse. This ensures that charged air masses can pass through the gap between the bottom of the pressing roller 31 and the carpet contact area, preventing large amounts of air masses from being discharged from the dust removal gap 32 at the top of the pressing roller 31. This improves the utilization rate of charged air masses and reduces energy consumption costs.
[0027] Specifically, after the cam 12 rotates downwards and rests against the extension plate and top plate 19, the entire lifting plate 18 is pressed downwards. The bottom of the lifting plate 18 drives the diversion channel 24, the first enclosure plate 25, and the second enclosure plate 26 to move downwards. The first enclosure plate 25 blocks the two ends of the area. The first enclosure plate 25 is briefly attached to the surface of the pressing wheel 31 by the sealing gasket 27 at the bottom. Combined with the side of the first enclosure plate 25 blocking the dust removal gap 32, the diffusion area of the subsequently generated positively and negatively charged gas clouds can be limited to the maximum extent. At this time, the conductive sheet 13 and the conductive wire 23 at the top will also make instantaneous contact, causing high voltage to appear at the tip of the discharge needle 29. Ionized air generates ionized wind. At this time, filtered pure air is sprayed out towards the bottom through the air supply pipe 7 along the jet hole 28. The air mass is sprayed towards the bottom and diffuses into any gap area on the carpet surface below within the narrow bottom area. This ensures that the area not in contact with the pressing wheel 31 can also be neutralized by static electricity. The air mass can only pass through the tiny gap formed by the bottom of the pressing wheel 31 and the carpet. This allows the air mass to fully contact the carpet surface. This process ends when the cam 12 rotates out of the clamping groove 22 and the inner antistatic mechanism 5 is pulled upward by the return spring 38.
[0028] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
