Description

Technical Field

[0001] This utility model relates to the field of long-lasting static electricity elimination technology for PET sheet surfaces, specifically a long-lasting static electricity elimination device for PET sheet surfaces. Background Technology

[0002] PET sheet surface static elimination equipment is specifically designed to reduce or eliminate static electricity on the surface of PET sheets. Static electricity is mainly generated during the processing of PET sheets, such as die-cutting and slicing, due to friction and separation. The accumulation of static electricity can affect the performance of PET sheets and production efficiency, thus requiring effective static elimination.

[0003] A static electricity elimination device for PET sheet surface disclosed in Chinese Utility Model Patent Application Publication CN220935368U includes a housing. From left to right, the upper end of the housing is provided with a conveying mechanism, a first limiting mechanism, a dust removal device, a static electricity elimination device, and a second limiting mechanism. The dust removal device includes a controller mounted on one side of the housing. A control panel is mounted on one side of the controller. A pipe is mounted on one side of the controller, and an air jet device is mounted on the other side of the pipe. The air jet device includes a sliding shaft and an air nozzle mounted at the lower end of the device. The controller is also equipped with a slide rail, the other side of which is connected to a fixing plate, and one side of the fixing plate is connected to the housing. A dustproof plate is installed on one side of the slide rail. Through the cooperation between the air jet device, the slide rail, and the sliding shaft, dust adhering to the material can be quickly cleaned. Although the above device blows away the dust on the PET sheet using a dust removal device and then uses an antistatic device to eliminate static electricity from the PET sheet, the above device still has some drawbacks: First, although the above device uses an antistatic device, it only uses one type of antistatic device. In long-term operation, the device cannot achieve 100% antistatic removal of the PET sheet. This will result in the processed PET sheet failing the acceptance test and requiring a second antistatic removal. This not only involves secondary processing but also... First, the work delayed factory production and increased the workload of workers. Second, although the aforementioned device is equipped with a dust removal system, it can only blow away the floating dust on the upper surface of the PET sheet, leaving the floating dust and other adhering substances on the lower surface unremoved. This results in the PET sheet's lower surface not achieving the required antistatic effect. Third, although the aforementioned device has an antistatic system, it only performs antistatic treatment on the upper surface of the PET sheet and cannot treat the lower surface. This means that when the treated PET sheet is rewound, the lower surface, having not been treated, is also contaminated by static electricity and adhering substances from the lower surface, requiring reprocessing. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a long-lasting static electricity elimination device for PET sheet surfaces. This solves the problems of insufficient static electricity removal devices, which prevent 100% treatment of the sheets after long-term use; dust removal devices that can only remove dust from the upper surface of the sheet, failing to treat the lower surface, resulting in poor static electricity removal on the lower surface; and static electricity removal devices that can only treat the upper surface, leaving the lower surface untreated, causing the entire sheet roll to be contaminated with static electricity and deposits from the untreated lower surface after winding, requiring reprocessing.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model has a reasonable structure. The device is equipped with an electrostatic eliminator module, a double roller electrostatic eliminator module, and an electrostatic eliminator fan module. When the PET sheet passes through these electrostatic eliminator modules, the combination of these modules can achieve multi-layer electrostatic elimination treatment on the surface of the PET sheet. After long-term use, even if one of these electrostatic eliminator modules malfunctions and cannot effectively eliminate the electrostatics on the surface of the PET sheet, the remaining electrostatic eliminator modules can still treat the untreated PET sheet surface to achieve comprehensive electrostatic elimination treatment. This greatly ensures the quality of electrostatic elimination treatment, reduces the need for rework, ensures factory production efficiency, and reduces the workload of workers.

At the same time, the electrostatic eliminator fan module is hollow in the middle, and the sheet walks out from the middle of the module. This allows the module to blow away the adhering substances on both the upper and lower surfaces of the sheet and neutralize the static electricity, achieving a very good electrostatic eliminator effect.

[0026] 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.

[0027] Example: Reference Figures 1-6 The device shown is a long-lasting static electricity elimination device for PET sheet surface, including a base plate 1. From left to right, the top of the base plate 1 is fixedly connected to a cargo winding module 2, a machine housing 3, a static electricity eliminator module 4, a double roller static electricity elimination module 5, a static electricity elimination fan module 6, and a cargo conveying module 7. Fixing blocks 8 are fixedly connected to both sides of the base plate 1. Hydraulic legs 9 are fixedly connected to the bottom of the fixing blocks 8. A hydraulic foot 10 is inserted into one end of the hydraulic leg 9.

[0028] The cargo winding module 2, machine housing 3, static eliminator module 4, double roller static eliminator module 5, static eliminator fan module 6, and cargo conveying module 7 are all welded to the base plate 1. The fixing block 8 is also welded to the side of the base plate 1. The hydraulic leg 9 is welded to the bottom of the fixing block 8. Finally, the hydraulic leg 9 is inserted into the hydraulic foot 10 to complete the assembly of the entire device.

[0029] The PET sheet roll is first installed onto the cargo conveying module 7, then the motor switch is turned on, and simultaneously the motor switch of the cargo winding module 2 is also turned on, synchronizing the conveying and winding speeds of the cargo winding module 2 and the cargo conveying module 7. Then, when the PET sheet begins to be conveyed, the motors of the static eliminator module 4, the double roller static eliminator module 5, and the static eliminator fan module 6 are all turned on and put into operation. This allows the PET sheet to first enter and pass through the static eliminator fan module 6 for the first step of removing adhering substances and neutralizing static electricity, and then immediately enter the double roller static eliminator module 5, where it is further processed by the double roller static eliminator fan module 6. The bidirectional rotation of the roller antistatic module 5 allows for better connection of PET sheets. It also enables direct contact between the rollers and the PET sheet, wiping the surface to eliminate static electricity. After exiting the roller antistatic module 5, the PET sheet enters the static eliminator module 4. As it passes through the static eliminator module 4, needle-like ions are emitted to remove static electricity from the PET sheet surface. Finally, the static-free PET sheet is wound onto the goods winding module 2, ready for packaging.

[0030] The device is equipped with an electrostatic eliminator module, a dual-roller electrostatic eliminator module, and an electrostatic eliminator fan module. When PET sheets pass through these electrostatic eliminator modules, the combination of these modules can achieve multi-layer electrostatic removal treatment on the surface of the PET sheets. After long-term use, even if one of these electrostatic eliminator modules malfunctions and cannot effectively remove static electricity from the PET sheet surface, the remaining electrostatic eliminator modules can still treat the untreated PET sheet surface to achieve comprehensive electrostatic removal treatment. This greatly ensures the quality of electrostatic removal treatment, reduces the need for rework, ensures factory production efficiency, and reduces the workload of workers.

[0031] The device also includes an electrostatic eliminator module 4 and a double roller electrostatic eliminator module 5. The electrostatic eliminator module 4 is designed with a hollow center, through which the sheet material passes, allowing for effective treatment of both the upper and lower surfaces of the sheet. The double roller electrostatic eliminator module 5 consists of two rotating rollers that rotate in opposite directions, on which electrostatic eliminator cloth is adhered to achieve better electrostatic removal on the upper and lower surfaces of the sheet material passing through.

[0032] like Figure 2 As shown, the cargo winding module 2 includes a first column 201, a base plate 1 fixedly connected to the bottom of the first column 201, a first pivot hole on the front of the first column 201, a first pivot installed on the inner wall of the first pivot hole, a first rotating rod 202 inserted into the inner wall of the first pivot, a second column 203 inserted into the first column 201 via the first rotating rod 202, a base plate 1 fixedly connected to the bottom of the second column 203, a first motor 204 inserted into one end of the first rotating rod 202, a first threaded hole base fixedly connected to both sides of the first motor 204, a first threaded hole on the top of the first threaded hole base, a first bolt 205 threadedly connected to the inner wall of the first threaded hole, a first motor placement platform 206 threadedly connected to the first motor 204 via the first bolt 205, and a first column 201 fixedly connected to the back of the first motor placement platform 206.

[0033] The first column 201 and the second column 203 are welded to the base plate 1. The first rotating shaft is installed into the first rotating shaft hole on the first column 201 of the first column. Then, the first rotating rod 202 is inserted into the first rotating shaft and pushed forward until the other end of the first rotating rod 202 is inserted into the second column 203. The first motor placement platform 206 is also welded to the first column 201. The first threaded hole base is welded to both sides of the first motor 204. The first motor 204 is placed on the first motor placement platform 206. Then, the first rotating rod 202 is inserted into the first motor 204. Finally, the first bolt 205 is screwed into the first threaded hole on the first threaded hole base and rotated until it is screwed into the first motor placement platform 206, thus completing the assembly of the cargo winding module 2.

[0034] First, insert one end of the first rotating rod 202 into the first rotating shaft. Then, insert the PET sheet roll into the other end of the first rotating rod 202. Next, insert the other end of the first rotating rod 202 into the second column 203. Then, insert the first rotating rod 202 into the first motor 204. After assembling, turn on the first motor 204 and adjust the rotation speed to ensure that the speed of winding the PET sheet is the same as the speed of conveying the PET sheet, so as to ensure that the conveying and winding process will not be easily interrupted.

[0035] like Figure 3As shown, the static eliminator module 4 includes a third column 401, with a base plate 1 fixedly connected to the bottom of the third column 401. A first vertical hole is formed on the front of the third column 401, and a first slot is formed on the back of the third column 401. A static eliminator 402 is engaged with the inner wall of the first slot. A fourth column 403 is engaged with the third column 401 via the static eliminator 402. The base plate 1 is fixedly connected to the bottom of the fourth column 403. A first connector 404 is fixedly connected to the front of the static eliminator 402. A cable 405 is inserted into the inner wall of the first connector 404. One end of the cable 405... A second connector 406 is plugged into the end. A static eliminator motor 407 is fixedly connected to the bottom of the second connector 406. A second threaded hole base is fixedly connected to both sides of the static eliminator motor 407. A second threaded hole is opened on the top of the second threaded hole base. A second bolt 408 is threadedly connected to the inner wall of the second threaded hole. A static eliminator motor placement platform 409 is threadedly connected to the static eliminator motor 407 through the second bolt 408. A machine housing 3 is fixedly connected to the back of the static eliminator motor placement platform 409. A cable hole is opened on the front of the machine housing 3. A cable 405 is inserted into the inner wall of the cable hole.

[0036] The third column 401 and the fourth column 403 are welded to the base plate 1. The first slot and the first vertical hole are integrally formed with the third column 401. One end of the static eliminator 402 is inserted into the first slot, and the other end is inserted into the fourth column 403. The first connector 404 is integrally formed with the static eliminator 402. The cable hole is integrally formed with the machine housing 3. One end of the cable 405 is inserted through the cable hole into the first connector 404, and the other end of the cable 405 is inserted into the second connector 406. The second connector 406 is also integrally formed with the static eliminator motor 407. The static eliminator motor placement platform 409 is welded to the machine housing 3. The second threaded hole base is integrally formed with the static eliminator motor 407. The second bolt 408 is screwed into the second threaded hole and rotated until it is screwed into the static eliminator motor placement platform 409, thus completing the assembly of the static eliminator module 4.

[0037] The static eliminator 402 is a common static elimination device. It neutralizes static electricity by releasing the opposite charge, thus achieving the effect of removing static electricity. This device typically consists of a high-voltage power supply and an ion emitter. It can be directly installed on the production line, close to the PET sheet processing area, to eliminate static electricity. When the PET sheet enters the static eliminator 402, because the static eliminator 402 has a hollow design in the middle, the static elimination motor 407 is turned on as the PET sheet passes through it. The high-voltage power is transmitted to the static eliminator 402 through the cable 405. As the PET sheet passes through the hollow area, the opposite charge is released simultaneously, neutralizing and removing the residual static electricity on the PET sheet, thus achieving the effect of removing static electricity. The advantage of this design is that the hollow design of the static eliminator 402 allows the PET sheet to pass through the middle area, effectively eliminating static electricity while also removing static electricity from both the upper and lower surfaces of the PET sheet. This prevents the PET sheet from being contaminated with static electricity and requiring secondary processing during winding, as the lower surface may not have been properly treated to remove static electricity.

[0038] like Figure 4 As shown, the dual-roller anti-static module 5 includes a fifth column 501, with a base plate 1 fixedly connected to the bottom of the fifth column 501. A second pivot hole and a third pivot hole are respectively opened on the front of the fifth column 501 from top to bottom. A second pivot is installed on the inner wall of the second pivot hole, and a second rotating rod 502 is inserted into the inner wall of the second pivot. A sixth column 503 is inserted into the fifth column 501 through the second rotating rod 502. The bottom of the sixth column 503 is fixedly connected to the base plate 1, and a first rotating roller 5 is inserted into the surface of the second rotating rod 502. 04. A first female Velcro fastener is fixedly connected to the surface of the first rotating roller 504.

[0039] A third rotating shaft is installed on the inner wall of the third rotating shaft hole. A third rotating rod 509 is inserted into the inner wall of the third rotating shaft. A sixth column 503 is inserted into the fifth column 501 through the third rotating rod 509. A second rotating roller 510 is inserted into the surface of the third rotating rod 509. A second female Velcro fastener is fixedly connected to the surface of the second rotating roller 510. A second static elimination cloth 511 is installed on the second rotating roller 510 through the second female Velcro fastener. A third motor 512 is inserted into one end of the third rotating rod 509. A fourth threaded hole base is fixedly connected to both sides of the third motor 512. A fourth threaded hole is opened on the top of the fourth threaded hole base. A fourth bolt 513 is threadedly connected to the inner wall of the fourth threaded hole. A third motor placement platform 514 is threadedly connected to the third motor 512 through the fourth bolt 513.

[0040] The front of the machine housing 3 has a first rotating rod hole and a second rotating rod hole respectively from top to bottom. The inner wall of the first rotating rod hole is inserted with a second rotating rod 502, and the inner wall of the second rotating rod hole is inserted with a third rotating rod 509. The back of the second motor placement platform 508 and the third motor placement platform 514 are fixedly connected to the machine housing 3.

[0041] The fifth column 501 and the sixth column 503 are welded to the base plate 1. The second rotating shaft is placed into the second rotating shaft hole, and then the second rotating rod 502 is inserted into the second rotating shaft. The second rotating rod 502 is then pushed forward. The first static elimination cloth 505 is attached to the surface of the first rotating roller 504. The first rotating roller 504 is then inserted onto the second rotating rod 502. The second rotating rod 502 is then pushed forward until it is inserted into the sixth column 502. The second motor placement platform 508 is welded to the machine housing 3. The second rotating rod 502 is inserted into the second motor 506. The second motor 506 is then placed on the second motor placement platform 508. The second motor placement platform 508 has third threaded hole bases welded on both sides. The third bolt 507 is screwed into the third threaded hole base and rotated until it is screwed into the second motor placement platform 508, thus completing the assembly of the upper roller static elimination device.

[0042] Install the third rotating shaft into the third rotating shaft hole, insert the third rotating rod 509 into the third rotating shaft and continue to insert it forward, then attach the second static elimination cloth 511 to the second rotating roller 510, then insert the second rotating roller 510 into the third rotating rod 509, and then continue to insert the third rotating rod 509 forward until it is inserted into the sixth column 503. The third motor placement platform 514 is welded to the machine housing 3 by welding. Place the third motor 512 on the third motor placement platform 514, insert the third rotating rod 509 into the third motor 512, and weld the fourth threaded hole base on both sides of the third motor 512. Screw the fourth bolt into the fourth threaded hole base and continue to rotate until it is screwed into the third motor placement platform 514 to complete the assembly of the lower roller static elimination device, thereby completing the assembly of the double roller static elimination module 5.

[0043] The first static eliminator cloth 505 and the second static eliminator cloth 511 are made of special fabric containing anti-static components. They remove static electricity by wiping the surface of the PET sheet. The first static eliminator cloth 505 and the second static eliminator cloth 511 are attached to the first rotating roller 504 and the second rotating roller 510 respectively using Velcro. When the PET sheet needs to pass through the double roller static eliminator module 5, the second motor 506 and the third motor 512 are turned on, causing the second rotating rod 502 and the third rotating rod 509 to rotate in opposite directions, thereby driving the first rotating roller 504 and the second rotating roller 510 to rotate in opposite directions. This ensures good continuity when the PET sheet enters and exits. At the same time, because the first static eliminator cloth 505 and the second static eliminator cloth 511 are also in direct contact with the surface of the PET sheet, they can effectively wipe the top and bottom surfaces of the PET sheet, thus better removing static electricity from the surface of the PET sheet.

[0044] like Figure 5As shown, the static eliminator fan module 6 includes a seventh column 601, with a base plate 1 fixedly connected to the bottom of the seventh column 601.

A static eliminator fan 602 is engaged with the inner wall of the second slot. An eighth column 603 is engaged with the seventh column 601 via the static eliminator fan 602. The base plate 1 is fixedly connected to the bottom of the eighth column 603. A third connector 604 is fixedly connected to the front of the static eliminator fan 602. A duct 605 is inserted into the inner wall of the machine housing. A fourth connector 606 is inserted into one end of the duct 605. A fan motor 607 is fixedly connected to the bottom of the fourth connector 606. A fifth threaded hole base is fixedly connected to both sides of the fan motor 607. A fifth threaded hole is opened at the top of the fifth threaded hole base. A fifth bolt 608 is threadedly connected to the inner wall of the fifth threaded hole. The fan motor 607 is threadedly connected to the fan motor placement platform 609 through the fifth bolt 608. A duct hole is opened on the front of the machine housing 3. A duct 605 is inserted into the inner wall of the duct hole.

[0045] The seventh column 601 and the eighth column 603 are welded to the base plate 1. One end of the static eliminator fan 602 is inserted into the seventh column 601 through the second slot, and the other end of the static eliminator fan 602 is inserted into the eighth column 603. The static eliminator fan 602 and the third connector 604 are integrally formed. The duct hole is opened on the machine housing 3. The fourth connector 606 is integrally formed with the fan motor 607. The fan motor mounting platform 60... 9 is welded to the machine housing 3 by welding. Place the fan motor 607 on the fan motor mounting platform 609, insert one end of the air duct 605 through the air duct hole into the third connector 604, and then insert the other end of the air duct 605 into the fourth connector 606. The fan motor 607 has fifth threaded hole bases welded on both sides. Screw the fifth bolt into the fifth threaded hole base and continue to rotate until it is screwed into the fan motor mounting platform 609 to complete the assembly of the static elimination fan module 6.

[0046] The static eliminator fan 602 combines the functions of a fan and a static eliminator. It generates airflow through the fan and releases ions to neutralize static electricity, thereby achieving the effect of removing static electricity. When the PET sheet enters the static eliminator fan 602, because the static eliminator fan 602 is also hollow in the middle, the fan motor 607 is turned on at the same time as the PET sheet enters. A large amount of air mixed with static charge is blown through the air duct 605 onto the upper and lower surfaces of the PET sheet. While blowing away the attached substances on the PET sheet, it also blows the static charge onto the surface of the sheet and performs preliminary static neutralization and static removal treatment on the surface of the sheet, solving some obstacles for subsequent static treatment.

[0047] The device is equipped with an antistatic blower module 6. This antistatic blower module 6 can not only blow air onto the surface of the PET sheet to remove the adhering substances on the surface of the sheet, but also blow out the ions in the antistatic blower 602 through the gas, thereby achieving the effect of neutralizing the static electricity on the surface of the sheet. At the same time, the module is hollow in the middle, and the sheet walks out from the middle of the module. This allows the module to blow away the adhering substances on both the upper and lower surfaces of the sheet and neutralize the static electricity, achieving a very good antistatic effect.

[0053] Verification of static elimination effect:

[0054] To scientifically and objectively evaluate the static elimination performance of this equipment, we used a professional static electricity tester (e.g., the EST102 static electricity attenuation tester) and measured the electrostatic potential of the PET sheet surface before and after treatment with this equipment, based on the test principle of the national standard GB / T 12703.6-2010 "Evaluation of electrostatic properties of textiles - Part 6: Corona discharge method".

[0055] Quantitative data support:

[0056] Test conditions:

[0057] Test equipment: EST102 electrostatic attenuation tester;

[0058] Environmental conditions: Temperature 23±2℃, relative humidity 45%±5%;

[0059] Test subject: A transparent PET sheet with a thickness of 0.5mm and a size of 200mm×200mm;

[0060] Pretreatment: Rub the PET sheet with a triboelectric device (such as a friction wheel) to stabilize its surface electrostatic potential at a high initial value;

[0061] Test method: Pass a PET sheet with high static electricity through the static eliminator fan module, the dual roller static eliminator module, and the static eliminator module of this equipment at a constant speed (e.g., 1 m / s). Measure and record the electrostatic potential at the equipment inlet (before treatment) and outlet (after treatment).

[0062] Test results:

[0063]

[0064] in conclusion:

[0065] The data above demonstrates that this device can rapidly reduce the static electricity on the surface of PET sheets from as high as ±6000V to within ±120V, with a static electricity attenuation rate consistently above 98%. This fully proves that the device's static electricity removal scheme, through the synergistic action of "fan blowing - roller wiping - ion neutralization," has an extremely excellent and stable static electricity elimination effect, meeting the stringent requirements for static electricity control on sheet surfaces in industrial production.

[0066] Applicability to different materials and thicknesses:

[0067] To verify the versatility of this equipment, we selected various PET sheets with different thicknesses and surface properties for testing to evaluate the universality of its static elimination effect.

[0068] Test conditions:

[0069] Test equipment: EST102 electrostatic attenuation tester;

[0070] Test subject:

[0071] Sample A: Standard transparent PET sheet, 0.25mm thick;

[0072] Sample B: Standard transparent PET sheet, 0.5mm thick;

[0073] Sample C: Standard transparent PET sheet, 1.0 mm thick;

[0074] Sample D: Matte surface PET sheet, 0.5mm thick;

[0075] Sample E: Antistatic coated PET sheet, 0.5mm thick;

[0076] Test method: Each sample is subjected to triboelectric charging to achieve an electrostatic potential of ±3000V~±4000V, and then processed using this equipment. The electrostatic potential after processing is then measured.

[0077] Test results:

[0078]

[0079] in conclusion:

[0080] Test results show that this equipment is not only suitable for PET sheets of standard thickness, but also exhibits excellent static elimination capabilities for ultra-thin (0.25mm) and thicker (1.0mm) PET sheets. Furthermore, it effectively eliminates static electricity generated by friction on PET sheets with a certain degree of roughness, such as matte surfaces, and those with inherent antistatic coatings. This demonstrates the equipment's broad applicability and its ability to meet the production process requirements of various PET sheets.

[0081] Dust removal effect verification:

[0082] To verify the dust removal capabilities of this equipment, especially the static eliminator fan module and the dual roller static eliminator module, we used a combination of weighing and microscopic observation methods for testing.

[0083] 1. Quantitative data support (weighing method)

[0084] Test conditions:

[0085] Test subject: 0.5mm thick PET sheet, 500mm × 500mm in size;

[0086] Source of contamination: Evenly spread ISO 12103-A1 standard test dust (general-purpose dust) on the surface of the sheet.

[0087] Test method:

[0088] The initial weight W1 of the contaminated sheet was measured using a high-precision electronic balance (accuracy 0.1 mg).

[0089] The sheet is processed through this equipment at a constant speed;

[0090] Weigh the processed sheet again, and the weight W2 will be measured.

[0091] Calculate the dust removal rate: (W1 - W2) / W1 × 100%;

[0092] Test results:

[0093]

[0094] in conclusion:

[0095] Through weighing tests, this equipment demonstrates an extremely high ability to remove standard dust adhering to the surface of PET sheets, with a dust removal rate consistently above 99%. This is primarily attributed to the powerful and clean airflow generated by the electrostatic eliminator fan module, which effectively blows away floating dust and particulate matter from the sheet surface. Meanwhile, the physical wiping action of the dual-roller electrostatic eliminator module removes some stubborn deposits. The combination of these two methods achieves highly efficient surface cleaning.

[0096] Applicability to different types of dust:

[0097] To simulate the complex working conditions in a real production environment, we selected several representative types of industrial dust for testing.

[0098] Test conditions:

[0099] Testing equipment: Electron microscope (SEM), digital camera;

[0100] Test subject: 0.5mm thick PET sheet;

[0101] Source of pollution:

[0102] Type 1: Carbon black (representing fine, highly conductive black powder);

[0103] Type 2: Calcium carbonate powder (representing common industrial filler dust);

[0104] Type 3: Oily mixed dust (a small amount of lubricating oil is mixed into carbon black to simulate an oily environment);

[0105] Test method: Sprinkle the above three types of dust on the surface of the sheet respectively, observe and photograph the surface condition before and after treatment with the naked eye, and use an electron microscope for microscopic comparison if necessary;

[0106] Test Results and Evaluation:

[0107] Type 1 (Carbon Black):

[0108] Before processing: The sheet surface is uniformly black, with dense black particles visible to the naked eye;

[0109] After treatment: The sheet surface is restored to a smooth and transparent state, with only trace amounts of residue in localized areas; the overall dust removal effect is excellent. The airflow from the fan effectively disperses the dust, and the rollers wipe away most of it.

[0110] Type 2 (Calcium Carbonate Powder):

[0111] Before treatment: The sheet surface is covered with a layer of white powder, and the gloss is significantly reduced;

[0112] After treatment: The sheet surface is shiny and new, the white powder has been largely removed, and there is no visible residue. The calcium carbonate particles are relatively large and are more easily blown away by the airflow;

[0113] Type 3 (Oily Mixed Dust):

[0114] Before treatment: Dust and oil stains mixed together, forming a sticky sludge that adhered firmly to the surface of the sheet;

[0115] After treatment: Most of the oily stains and dust on the sheet surface have been removed, with only a small number of extremely difficult-to-remove oily residues. This indicates that the equipment is effective for both ordinary and oily dust, but its ability to remove heavy oil stains is somewhat limited. It can be used in conjunction with a pre-cleaning process in actual production.

[0116] in conclusion:

[0117] This equipment has a near-perfect removal effect on dry dust (such as carbon black and calcium carbonate). It also demonstrates good cleaning ability for mixed dust containing a small amount of oil. Test results prove that the dust removal module designed in this equipment can meet the dust removal needs of most PET sheet processing processes, ensuring that the sheets have a clean surface before entering the subsequent static elimination and winding processes, thereby guaranteeing the quality of the final product.
