Description

Technical Field

[0001] This utility model belongs to the field of PET sheet technology, specifically relating to a device for eliminating static electricity on the surface of PET sheets. Background Technology

[0002] PET possesses excellent mechanical properties, resistance to oil, grease, dilute acids, dilute alkalis, and most solvents. It also exhibits high transparency, blocks ultraviolet rays, and has good gloss. A search revealed that application number CN202320952075.4 discloses "a static electricity elimination device for PET sheet surface," which describes how "rotating a knob allows the threaded rod to move on one side of the working cover, thereby moving the pressure block. The distance can be adjusted according to different sheet sizes, offering flexibility and convenience. The grooves on the pressure block press against the edges of the sheet, ensuring its flatness. Under the action of the static eliminator, a large number of positive and negative ions are blown onto the sheet surface to neutralize static electricity. The working cover further facilitates the stability of the entire process." The system is effective in eliminating static electricity from the passing sheets, providing more comprehensive and thorough coverage, which is beneficial for subsequent processing. By rotating the knob, the threaded rod can be moved to one side of the work cover, which in turn moves the pressure block. The distance can be adjusted according to different sheet sizes, offering flexibility and convenience. The grooves on the pressure block press down on the edges of the sheet, ensuring its flatness. Under the action of the static eliminator, a large number of positive and negative ions are blown onto the surface of the sheet to neutralize static electricity. The work cover further contributes to the stability and effectiveness of the entire process, ensuring more comprehensive and thorough coverage and facilitating subsequent processing. However, the above comparison document still has the following problems in actual use:

[0003] In actual use, the leeward side cannot remove static electricity; it can only remove static electricity from one side, resulting in a limited range. Furthermore, it is inconvenient to clean the surface during use, leading to poor static electricity removal efficiency.

[0004] Therefore, providing a device that can clean dust and eliminate static electricity on both sides is highly practical. Utility Model Content

[0026] Example

[0027] Please see Figure 1-4 A static electricity elimination device for PET sheet surface includes a connecting frame 100, a dust cleaning component 200, and a static electricity elimination component 300.

[0028] Please refer to the details. Figure 1 Several support frames 110 are provided on both sides of the connecting frame 100.

[0029] Please see Figure 1-4 The dust cleaning component 200 includes a connecting box 210 disposed at the top end of the connecting frame 100. A vacuum cleaner 220 is disposed at the top of the connecting box 210. A suction tube 230 is sealed and connected to one side of the vacuum cleaner 220. A connector is sealed and connected to the end of the suction tube 230. A distribution tube 240 is sealed and connected to one side of the connector. The end of the distribution tube 240 passes through the connecting frame 100 and is sealed and connected to two dust collection chambers 250. An ultrasonic generator 260 is disposed at the top and bottom ends of the inner wall of the connecting frame 100.

[0030] In one specific embodiment, the ultrasonic generator 260 allows the user to easily pass the PET sheet through the connecting frame 100 when winding it up. At this time, the controller will turn on the vacuum cleaner 220 and the ultrasonic generator 260. The ultrasonic generator 260 generates ultrasonic waves, which resonate with the PET sheet, loosening the dust on its surface. The vacuum cleaner 220 then quickly sucks in the loosened dust through the suction chamber 250 and transmits it to the connector through the distribution pipe 240. The connector sends the dust to the suction pipe 230 and into the vacuum cleaner 220. The vacuum cleaner 220 discharges the sucked-in dust through the discharge pipe 400 into the collection box 500 in the connecting box 210. The collection box 500 can then be cleaned by using the handle, thus achieving the purpose of cleaning the dust and avoiding affecting the static electricity elimination efficiency.

[0031] Please see Figure 2-4The static elimination component 300 includes a sealed box 310 disposed at the other end of the top of the connecting frame 100. The inner wall of the sealed box 310 is provided with two bipolar ion rods 320. The bottom of the sealed box 310 is sealed and connected to several connecting pipes 330. The bottom of each of the several connecting pipes 330 passes through the inner wall of the connecting frame 100 and is sealed and connected to the top of the connecting frame 100. A nozzle 340 is sealed and connected to the top of the sealed box 310. An air pump 350 is sealed and connected to one side of the air pump 350. A delivery pipe 360 ​​is sealed and connected to the bottom of the inner wall of the connecting frame 100. A connecting strip 370 is slidably connected to the bottom of the inner wall of the connecting frame 100. Several bristles 380 are disposed on the top of the connecting strip 370.

[0032] In one specific embodiment, the bipolar ion bar 320 is provided. During use, the user needs to ground the connecting strip 370 and the brush bristles 380. When the PET sheet moves within the connecting frame 100, the controller will turn on the bipolar ion bar 320 and the air pump 350. The bipolar ion bar 320 generates ion clusters, and the air pump 350 generates gas, which is then sent into the sealed box 310 through the delivery pipe 360. The gas will carry the ion clusters and spray them onto the top of the PET sheet through the connecting pipe 330 and the nozzle 340 to eliminate static electricity on the top. The bottom of the sheet will come into contact with the brush bristles 380, and the brush bristles 380 and the connecting strip 370 will ground the static electricity on the bottom to the ground, thus achieving the purpose of eliminating static electricity on both sides.

[0033] Please see Figure 4 The other side of the vacuum cleaner 220 is sealed and connected to the discharge pipe 400. The end of the discharge pipe 400 is sealed and connected to the connecting box 210. The inside of the connecting box 210 is a slidably connected collection box 500. One end of the collection box 500 is provided with a handle.

[0034] In one specific embodiment, a handle is provided so that the user can easily pull out the collection box 500 to clean the dust inside, thus improving the convenience of use.

[0035] Please see Figure 1 The connecting frame 100 has several support plates 600 on both sides. Inside each support plate 600 are two electric telescopic rods 700. At the bottom of each electric telescopic rod 700 are fixed plates 800. The middle of each fixed plate 800 is fixedly connected to the connecting strip 370.

[0036] In one specific embodiment, the electric telescopic rod 700 is provided so that the controller can open the electric telescopic rod 700 during use, thereby extending or retracting it to move the fixing plate 800, which in turn moves the connecting strip 370, which in turn moves the brush bristles 380, so that the brush bristles 380 come into contact with the PET sheet.

[0037] Please see Figure 1Two reinforcing rods 900 are set in the middle of several support frames 110.

[0038] In one specific embodiment, the reinforcement rod 900 facilitates the reinforcement of the support frame 110 during use, making the support frame 110 more stable during use, avoiding swaying and improving stability.

[0039] Please see Figure 4 The end of the conveying pipe 360 ​​is sealed and connected to the sealing box 310, and the ends of the two dust collection chambers 250 are fixedly connected to the top and bottom of the inner wall of the connecting frame 100, respectively.

[0040] In one specific embodiment, the provided sealing box 310 facilitates the sealing and protection of the generated ion clusters during use, allowing them to be accurately sprayed onto the PET sheet through the nozzle 340 to eliminate static electricity.

[0041] Please see Figure 1 Several support frames 110 are made of titanium alloy, and controllers are provided at the top corners of the connecting frame 100.

[0042] In one specific embodiment, the titanium alloy provided allows the support frame 110 to be made more robust and durable during use, thus improving its stability.

[0043] Please see Figure 1-4 The vacuum cleaner 220, ultrasonic generator 260, bipolar ion bar 320, air pump 350 and electric telescopic rod 700 are all electrically connected to the controller, and the controller is electrically connected to an external power source.

[0044] In one specific embodiment, the provided controller facilitates the power supply to the electrical equipment when it needs power, avoiding the situation where it cannot be powered when power is needed, thus improving stability.

[0045] In use, the ultrasonic generator 260 facilitates the operation of the PET sheet by passing it through the connecting frame 100 during winding. The controller then activates the vacuum cleaner 220 and the ultrasonic generator 260. The ultrasonic generator 260 generates ultrasonic waves that resonate with the PET sheet, loosening the surface dust. The vacuum cleaner 220 quickly sucks in the loosened dust through the suction chamber 250 and transmits it to the connector via the distribution pipe 240. The connector then sends the dust into the suction pipe 230, where it enters the vacuum cleaner 220. The vacuum cleaner 220 discharges the sucked-in dust through the discharge pipe 400 into the collection box 500 within the connecting box 210. The collection box 500 can then be pulled out using the handle for dust removal. To avoid affecting the efficiency of static elimination, the bipolar ion bar 320 is used. During use, the connecting strip 370 and brush bristles 380 need to be grounded. When the PET sheet moves within the connecting frame 100, the controller will turn on the bipolar ion bar 320 and the air pump 350. The bipolar ion bar 320 generates ion clusters, and the air pump 350 generates gas, which is then sent into the sealed box 310 through the delivery pipe 360. Finally, the gas will carry the ion clusters and spray them onto the top of the PET sheet through the connecting pipe 330 and the nozzle 340 to eliminate static electricity on the top. The bottom of the sheet will come into contact with the brush bristles 380, and the brush bristles 380 and the connecting strip 370 will be grounded to conduct the static electricity on the bottom to the ground, thus achieving the purpose of eliminating static electricity on both sides.
