Technical Field
[0001] The utility model relates to a silicon coating device, belonging to the field of PET sheet material processing. Background Art
[0002] PET sheet is a new type of plastic product produced by a series of compression polymerization processes using high-precision machinery. It is widely used in many industries due to its advantages of good sensitivity, excellent transparency, good ductility and plasticity, and stable structure. After the PET sheet is produced, spraying silicone oil on its surface can prevent the PET sheet from being physically or chemically damaged.
[0003] In the prior art, the commonly used PET sheet silicon coating device will dip the silicone oil in the silicone oil tank through the continuous rotation of the oil-applying roller when the sheet passes between the rotating roller and the oil-applying roller, and evenly coat the silicone oil on the PET sheet. However, as the use time increases, the silicone oil in the silicone oil tank will gradually decrease and the liquid level of the silicone oil stored in the silicone oil tank will continue to decrease. When the liquid level of the silicone oil drops to a certain level, the oil-applying roller will not be able to contact and dip the silicone oil. At this time, it is necessary to add silicone oil to the silicone oil tank to ensure the normal operation of the equipment. This results in the need to add silicone oil to the silicone oil tank when the silicone oil in the silicone oil tank is not exhausted, resulting in the inability to fully utilize the silicone oil in the silicone oil tank, which greatly increases the frequency of adding silicone oil, increases the workload of workers, and reduces processing efficiency.

DETAILED DESCRIPTION
[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0020] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a silicon coating device, including a base 1, two first support frames 2 are fixedly connected to the top of the base 1, conveying rollers 3 are rotatably connected inside the two first support frames 2, a tension adjustment component 4 is fixedly connected to the top of the base 1 at one side of the first support frame 2, and a silicon coating component 5 is fixedly connected to the top of the base 1 at one side of the tension adjustment component 4.
[0021] The tension adjusting spring 45 and the slider 44 in the tension adjusting assembly 4 can drive the tension adjusting roller 46 to slide up and down along the guide rod 43, so that the tension of the PET sheet conveying can be automatically adjusted according to the conveying condition of the PET sheet;
[0022] Silicone oil can be sprayed onto the surface of the oil-applying roller 53 through the oil pump 56, the silicone oil tank 55 and the oil distribution pipe 54 in the silicon coating component 5. When the PET sheet passes between the rotating roller 52 and the oil-applying roller 53, the rolling oil-applying roller 53 will evenly coat the silicone oil on the surface of the PET sheet, thereby realizing the silicon coating process of the PET sheet. The excess silicone oil during the spraying process will fall back into the silicone oil tank 55 due to the effect of gravity, thereby realizing the recycling of the silicone oil.
[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The tension adjustment assembly 4 includes two second support frames 41 fixedly connected to the top of the base 1. A slide groove 42 is provided in the second support frame 41. A guide rod 43 is fixedly connected to the inner wall of the slide groove 42. A slider 44 is slidably connected to the surface of the guide rod 43. A tension adjustment spring 45 is fixedly connected to the bottom end of the slider 44. The tension adjustment spring 45 is fixedly connected to the inner wall of the slide groove 42. The slider 44 is rotatably connected to a tension adjustment roller 46 on the side away from the inner wall of the slide groove 42. When the silicon coating device is in operation, the conveying tension of the PET sheet will change as the PET sheet is conveyed. At this time, due to the loss of the extrusion of the PET sheet, the tension adjustment spring 45 will reset and push the tension adjustment roller 46 connected to the slider 44 to slide upward along the guide rod 43, thereby flattening the PET sheet, so that the tension of the PET sheet conveying can be automatically adjusted according to the conveying condition of the PET sheet, avoiding the phenomenon of uneven silicon coating due to wrinkles on the PET sheet, which is beneficial to improving the quality of silicon coating.
[0024] The silicon coating component 5 includes two third support frames 51 fixedly connected to the top of the base 1, and rollers 52 are rotatably connected in the two third support frames 51. An oil-applying roller 53 is rotatably connected in the two third support frames 51 above the rollers 52, and an oil suction sleeve is fixedly connected to the surface of the oil-applying roller 53. An oil distribution pipe 54 is fixedly connected above the oil-applying roller 53 in the two third support frames 51, and a plurality of nozzles are fixedly connected to the bottom end of the oil distribution pipe 54. A silicone oil tank 55 is fixedly connected to the top of the base 1 below the rollers 52, and an oil pump 56 is fixedly connected to the top of the base 1 on one side of the silicone oil tank 55. The oil pump 56 and the oil distribution pipe 54, as well as the oil pump 56 and the silicone oil tank 55 are connected by pipelines. When the silicon coating device is in operation, the oil pump 56 will continuously extract the silicone oil in the silicone oil tank 55 and transport it to the oil distribution pipe 54. The oil distribution pipe 54 will spray silicone oil onto the surface of the oil attachment roller 53 through a number of nozzles connected to its bottom end. At this time, the oil suction sleeve connected to the surface of the oil attachment roller 53 will absorb the silicone oil. When the PET sheet passes between the rotating roller 52 and the oil attachment roller 53, the rolling oil attachment roller 53 will evenly coat the silicone oil on the surface of the PET sheet, thereby realizing the silicon coating process of the PET sheet. During the spraying process, excess silicone oil will fall back into the silicone oil tank 55 due to the effect of gravity, thereby realizing the recycling of the silicone oil, which is beneficial to reducing the consumption of silicone oil and thus reducing the processing cost.
[0025] The width of the silicone oil groove 55 is greater than the diameter of the oiling roller 53. The first fixing frame 6 is fixedly connected to the top of both sides of the third support frame 51, and a baffle 7 is movably connected inside the first fixing frame 6. By providing the baffle 7 and making the width of the silicone oil groove 55 greater than the diameter of the oiling roller 53, it is ensured that the silicone oil will not fall outside the silicone oil groove 55 during the process of spraying silicone oil on the oiling roller 53, thereby ensuring the cleanliness of the processing environment. The baffle 7 can be disassembled by pulling it upward to separate it from the first fixing frame 6, so that it is convenient to clean and replace the baffle 7.
[0026] The inner wall of the silicone oil tank 55 is fixedly connected with a second fixing frame 8, the top of the second fixing frame 8 is movably connected with a filter screen 9, the top of the filter screen 9 is fixedly connected with a handle, and the top surface of the filter screen 9 is lower than the top surface of the silicone oil tank 55. The filter screen 9 can prevent dust or foreign matter from falling into the silicone oil tank 55, thereby improving the quality of silicone coating, and the top surface of the filter screen 9 is lower than the top surface of the silicone oil tank 55 to prevent silicone oil from falling out of the silicone oil tank 55.
[0027] The inner wall at the bottom of the silicone oil tank 55 is inclined, and an observation window 10 is fixedly connected to one side of the silicone oil tank 55. The observation window 10 is made of transparent material. The inner wall at the bottom of the silicone oil tank 55 is inclined, which can guide the silicone oil stored in the silicone oil tank 55 to the oil pump 56, so that the oil pump 56 can extract the silicone oil, which is beneficial to reducing the residual silicone oil in the silicone oil tank 55. The observation window 10 is provided to facilitate observation of the specific situation of the silicone oil in the silicone oil tank 55, so as to add or replace the silicone oil in time.
[0028] Specific implementation method: first, one end of the PET sheet is passed through the bottom of the conveying roller 3 connected to the first support frame 2 in the silicon coating device, the top of the tension adjustment roller 46 connected to the second support frame 41, and between the rotating roller 52 and the oil-applying roller 53 connected to the third support frame 51, and then the PET sheet is flattened and one end of it is fixed to the surface of the external winding device. At this time, the flattened PET sheet will squeeze the tension adjustment roller 46 located below it, so that the sliders 44 connected on both sides thereof slide downward along the surface of the guide rod 43 connected to the slide groove 42, thereby contracting the tension adjustment spring 45. In the process of processing the PET sheet, the external winding device will drive the conveying roller 3, the tension adjustment roller 46, the rotating roller 52 and the oil-applying roller 53 to rotate;
[0029] When the silicon coating device is in operation, the conveying tension of the PET sheet will change as the PET sheet is conveyed. At this time, due to the loss of the extrusion of the PET sheet, the tension adjustment spring 45 will be reset and push the tension adjustment roller 46 connected to the slider 44 to slide upward along the guide rod 43, thereby flattening the PET sheet. In this way, the conveying tension of the PET sheet can be automatically adjusted according to the conveying condition of the PET sheet, avoiding the uneven silicon coating caused by wrinkles on the PET sheet, which is beneficial to improving the quality of silicon coating.
[0030] When the silicon coating device is in operation, the oil pump 56 will continuously extract the silicone oil in the silicone oil tank 55 and transport it to the oil distribution pipe 54. The oil distribution pipe 54 will spray silicone oil onto the surface of the oil attachment roller 53 through a number of nozzles connected to its bottom end. At this time, the oil suction sleeve connected to the surface of the oil attachment roller 53 will absorb the silicone oil. When the PET sheet passes between the rotating roller 52 and the oil attachment roller 53, the rolling oil attachment roller 53 will evenly coat the silicone oil on the surface of the PET sheet, thereby realizing the silicon coating process of the PET sheet. During the spraying process, excess silicone oil will fall back into the silicone oil tank 55 due to the effect of gravity, thereby realizing the recycling of the silicone oil, which is beneficial to reducing the consumption of silicone oil and thus reducing the processing cost.
[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
