Description

Technical Field

[0001] This utility model belongs to the field of antistatic technology, and more specifically, it relates to an antistatic equipment for online coating of polyester film. Background Technology

[0002] During the online coating process of polyester film, the polyester film is prone to static electricity. Static electricity on the surface of the polyester film needs to be eliminated by static elimination devices such as ion bars. When the ion bars are working, they release ions of opposite polarity onto the film surface with static charge, neutralizing the positive and negative charges, thereby reducing or eliminating surface static electricity and preventing static electricity from having an adverse effect on the coating process and product quality.

[0003] For example, CN212992668U discloses an ion fan bar. By setting up a protective shell, a gas source kit, and a discharge kit, in actual application, when the ion fan bar is working, the gas from the external gas source is sequentially delivered to each discharge needle through the gas supply pipe and the gas storage device. Then, the copper rod is subjected to high voltage, and under the action of the insulating ring layer, each aluminum tube will generate an induced voltage. The induced voltage is then transmitted to each discharge needle, and each discharge needle generates a gas cloud with positive and negative charges, completing the electrostatic elimination work. Since the length of each aluminum tube is greatly reduced compared to the long cylindrical aluminum tubes in the prior art, that is, the internal resistance of each aluminum tube is small, the induced voltage will not be too severely attenuated, so that the induced voltage transmitted to the discharge needle can enable the discharge needle to work normally, and the stability and reliability are greatly improved.

[0004] Based on the above, the ion bar needs to maintain a suitable distance from the polyester film during installation. Therefore, the installation position of the ion bar needs to be measured manually by the staff, which takes a long time and affects the installation efficiency of the ion bar. This results in a long downtime of the coating equipment and affects the coating efficiency of the polyester film. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an online antistatic coating device for polyester film. This addresses the issue that during installation, the ion bar needs to maintain a suitable distance from the polyester film. Therefore, workers must manually measure the installation position of the ion bar, which takes a considerable amount of time, affecting the installation efficiency and leading to prolonged downtime for the coating equipment, ultimately impacting the coating efficiency of the polyester film.

[0006] The purpose and effectiveness of this utility model's online polyester film coating antistatic equipment are achieved through the following specific technical means:

[0007] An online antistatic coating device for polyester film includes an ion bar body, positioning mounting plates, limiting connecting rods, limiting connecting sleeves, a connecting structure, a detection structure, and aluminum alloy pressure blocks. Two positioning mounting plates are provided, fixedly connected to the front and rear sides of the ion bar body respectively. Four limiting connecting rods are provided, fixedly connected to the left and right sides of the two positioning mounting plates respectively.

[0009] Furthermore, the detection structure includes a duct connection port and a first positioning connection ring; there are two duct connections, which are respectively fixedly connected to the left and right sides of the ion bar body, and rubber sealing gaskets are provided on the inner side of each of the two duct connections; there are two first positioning connection rings, which are respectively threaded to the outer side of the two duct connections.

[0010] Furthermore, the detection structure also includes a leak-proof rubber ring and a second positioning connecting ring; two leak-proof rubber rings are provided, and the two leak-proof rubber rings are respectively rotatably connected to the outside of the two first positioning connecting rings; two second positioning connecting rings are provided, and the two second positioning connecting rings are respectively rotatably connected to the outside of the two leak-proof rubber rings.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses aluminum alloy pressure blocks to press the polyester film firmly, reducing the shaking of the polyester film caused by wind. This reduces fluctuations in the distance between the coating head and the film, ensuring uniform coating thickness and improving the coating quality of the polyester film. Adjusting the position of the aluminum alloy pressure blocks directly determines the installation height of the ion bar, effectively avoiding deviations that occur when manually measuring height. This saves considerable time, improves the installation efficiency of the ion bar, shortens the downtime of the coating equipment, and increases the coating efficiency of the polyester film. An air-proof rubber ring provides auxiliary sealing to the duct connection and the duct joint, ensuring normal operation of the ion bar for a short period even after the rubber sealing gasket fails. This effectively guarantees the electrostatic removal effect on the polyester film and promptly issues an alarm to remind personnel to replace the rubber sealing gasket after seal failure, thus improving the overall performance of the ion bar.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides an online antistatic coating device for polyester film, including an ion bar body 1, a positioning mounting plate 2, a limiting connecting rod 3, a limiting connecting sleeve 4, a connecting structure, a limiting connecting plate 5, and an aluminum alloy pressure block 6. Two positioning mounting plates 2 are provided, fixedly connected to the front and rear sides of the ion bar body 1 respectively. Four limiting connecting rods 3 are provided, fixedly connected to the left and right sides of the two positioning mounting plates 2 respectively. The outer side of the limiting connecting rod 3 is provided with scale lines, and the lower part of the limiting connecting rod 3 is provided with threads. Four limiting connecting sleeves 4 are provided, threadedly connected to the lower parts of the four limiting connecting rods 3 respectively. Two limiting connecting plates 5 are provided, rotatably connected to the lower parts of the two front limiting connecting sleeves 4 and the two rear limiting connecting sleeves 4 respectively. The connecting structure is located inside the limiting connecting plates 5. Two aluminum alloy pressure blocks 6 are provided, slidingly connected to the lower parts of the two limiting connecting plates 5 respectively.

[0026] The connecting structure includes a synchronous transmission structure 401 and a reset elastic element 601. The synchronous transmission structure 401 is a synchronous belt drive mechanism. There are two synchronous transmission structures 401. The two front limit connecting sleeves 4 and the two rear limit connecting sleeves 4 are respectively connected by a synchronous transmission structure 401. There are multiple reset elastic elements 601. The two aluminum alloy pressure blocks 6 are elastically connected to the two limit connecting plates 5 through multiple reset elastic elements 601.

[0027] The specific usage and function of this embodiment are as follows: When installing the ion bar, it is necessary to first determine the distance between the nozzle of the ion bar and the polyester film. At this time, rotate the limiting connecting sleeve 4 so that the limiting connecting sleeve 4 drives the limiting connecting plate 5 and the aluminum alloy pressure block 6 to move along the limiting connecting rod 3 at the bottom of the positioning mounting plate 2. Determine the position of the limiting connecting sleeve 4 according to the scale on the limiting connecting rod 3. The synchronous transmission structure 401 can make the limiting connecting sleeves 4 on both sides rotate simultaneously. After determining the position of the limiting connecting sleeve 4 and the aluminum alloy pressure block 6, make the aluminum alloy pressure block 6 fit with the polyester film. Then, install the ion bar body 1 on the coating device. After the ion bar is installed, the air duct will flow into the ion bar and blow it from the nozzle to the polyester film. At this time, the air carries ions with opposite polarity to the film surface, which can reduce or eliminate the static electricity on the surface of the polyester film. The reset elastic element 601 will continuously press the aluminum alloy pressure block 6, so that the aluminum alloy pressure block 6 fits tightly with the polyester film.

[0028] Example 2:

[0029] As attached Figure 3 To be continued Figure 5 As shown:

[0030] Based on Embodiment 1, a detection structure is also included; the detection structure is disposed on the outside of the ion bar body 1.

[0031] The detection structure includes a duct connection port 101 and a first positioning connecting ring 103. There are two duct connection ports 101, which are fixedly connected to the left and right sides of the ion bar body 1, respectively.

[0032] The detection structure also includes a leak-proof rubber ring 104 and a second positioning connecting ring 108. There are two leak-proof rubber rings 104, which are rotatably connected to the outside of the two first positioning connecting rings 103 respectively.

At this time, the anti-leakage rubber ring 104 will cover the outside of the connection between the air duct connection port 101 and the air duct. When the seal of the rubber sealing gasket fails, the anti-leakage rubber ring 104 can be used temporarily as a sealing element to ensure the normal operation of the ion bar for a short period of time. At the same time, the anti-leakage rubber ring 104 will expand after being inflated, so that the first metal connecting piece 105 and the second metal connecting piece 107 come into contact. At this time, the control circuit of the audible and visual alarm 102 is turned on, and the audible and visual alarm 102 will sound an alarm to remind the staff to replace the rubber sealing gasket in time.
