Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cup coating technology and relates to a coating dust removal system. Background Technology
[0002] In existing technologies, during the lamination process of a cup-sealing production line, the sheets need to be manually installed onto the lamination device. The sheets move along the production line under the traction of the conveyor. After lamination, it is found that the foreign matter rate on the cover film is high. The reasons for the presence of foreign matter on the cover film are: firstly, inadequate protection was not provided during sheet installation, causing foreign matter to stick to the sheet; secondly, the sheet is exposed to the external environment during transport, and impurities in the air will be adsorbed onto the sheet. However, the lamination production line does not have a foreign matter removal structure, resulting in sheets containing foreign matter being covered on the cups for sealing, affecting product quality. Utility Model Content
[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a membrane dust removal system to remove foreign objects from the membrane.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A membrane dust removal system includes a negative pressure ionization device, a fan, and an ionization dust collector. The negative pressure ionization device includes a negative pressure generating cylinder, on which a first electrostatic eliminator and a first foreign object extraction shell are fixed. The first foreign object extraction shell is connected to the negative pressure generating cylinder. The two ends of the fan are connected to the negative pressure generating cylinder and the ionization dust collector through air ducts, respectively.
[0005] As a limitation of this utility model, a scraper is fixedly provided on the negative pressure generating cylinder, and the first negative pressure ionization device, the first foreign object exhaust shell and the scraper are arranged in sequence along the direction of sheet movement.
[0006] As a further limitation of this utility model, the side of the scraper that contacts the sheet is made of silicone and has a pointed shape.
[0007] As another limitation of this utility model, a second static eliminator and a second foreign object exhaust shell are also fixed on the negative pressure generating cylinder. The second foreign object exhaust shell is connected to the negative pressure generating cylinder. Along the direction of sheet movement, the first static eliminator, the first foreign object exhaust shell, the scraper, the second foreign object exhaust shell, and the second static eliminator are arranged in sequence.
[0008] As a limitation of this utility model, the exhaust port of the second foreign object exhaust shell is closer to the sheet material than the first foreign object exhaust shell, and the second static eliminator is closer to the sheet material than the first static eliminator.
[0009] As a further limitation of this utility model, both the first static eliminator and the second static eliminator are static eliminating rods.
[0010] As a third limitation of this utility model, the negative pressure generating cylinder is cylindrical.
[0011] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) The present invention sets up a dust removal system above the sheet, which can remove foreign objects attached to the sheet. At the same time, since the sheet is thin and easily carries static electricity, the foreign objects are more firmly adsorbed. The static eliminator of the present invention can effectively eliminate static electricity. The static eliminator rod is connected to a high voltage, thereby generating an electric field with positive and negative ions. When the sheet is affected by the electric field, the electron transfer will make the surface of the sheet neutral, making it easier for foreign objects to be drawn away by the negative pressure at the foreign object exhaust port, increasing the dust removal effect. The ionization dust collector can process the adsorbed foreign objects to prevent impurities from returning to the air and falling back onto the sheet, thereby improving the dust removal efficiency. (2) The scraper of this utility model can scrape off foreign objects that are firmly adsorbed, and can achieve better dust removal effect on foreign objects with stickiness. (3) This utility model adds an electrostatic eliminator and a foreign matter exhaust shell on the other side of the scraper for secondary dust removal, further ensuring dust removal efficiency, and is closer to the sheet material, resulting in stronger dust suction effect.
[0012] In summary, this invention can remove dust from sheet materials before sealing the film, achieving good dust removal effect, reducing product defect rate, and is suitable for dust removal of sheet-like films. Attached Figure Description
[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0014] Figure 1 This is a side view of an embodiment of the present utility model.

Second static eliminator; 15. Second foreign object exhaust shell; 2. Fan; 3. Ionization dust collector; 4. Air duct; 5. Scraper; 6. Sheet. Detailed Implementation
[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0017] Example: Covered membrane dust removal system like Figure 1As shown, this embodiment includes a negative pressure ionization device 1, a fan 2, and an ionization dust collector 3. Since this embodiment is for dust removal from a thin plastic sheet 6, which is prone to static electricity during transport, impurities in the air adhere to the sheet 6, and the static electricity makes the adhesion even stronger. Using only negative pressure suction is insufficient for dust removal. The negative pressure ionization device 1 eliminates static electricity at the adsorption site, making it easier to remove foreign objects. The fan 2 generates suction force, drawing the foreign objects into the ionization dust collector 3, preventing them from returning to the air and falling back onto the sheet 6.
[0018] The negative pressure ionization device 1 includes a negative pressure generating cylinder 11, which is cylindrical. A first static eliminator 12 and a first foreign object extraction shell 13 are fixedly mounted on the negative pressure generating cylinder 11. The first foreign object extraction shell 13 is connected to the negative pressure generating cylinder 11, and its outlet faces the sheet 6, located above the sheet 6. The two ends of the fan 2 are connected to the negative pressure generating cylinder 11 and the ionization dust collector 3 respectively through air ducts 4. The negative pressure generated by the fan 2 acts on the surface of the sheet 6 through the negative pressure generating cylinder 11 and the first foreign object extraction shell 13, drawing foreign objects into the ionization dust collector 3.
[0019] A scraper 5 is fixed on the negative pressure generating cylinder 11. The side of the scraper 5 that contacts the sheet 6 is made of silicone and has a pointed shape. Along the direction of movement of the sheet 6, the first negative pressure ionization device 1, the first foreign object exhaust shell 13 and the scraper 5 are arranged in sequence.
[0020] A second static eliminator 14 and a second foreign object extraction shell 15 are fixedly mounted on the negative pressure generating cylinder 11. The second foreign object extraction shell 15 is connected to the negative pressure generating cylinder 11, and its outlet faces the sheet 6, located above the sheet 6. Along the direction of sheet 6 movement, the first static eliminator 12, the first foreign object extraction shell 13, the scraper 5, the second foreign object extraction shell 15, and the second static eliminator 14 are arranged sequentially. Under the action of the scraper 5, foreign objects not sucked up by the first foreign object extraction shell 13 are further sucked up by the second foreign object extraction shell 15, resulting in double dust removal and improved efficiency. In this embodiment, both the first static eliminator 12 and the second static eliminator 14 are static eliminating rods.
[0021] To enhance the adsorption effect, the exhaust port of the second foreign object exhaust shell 15 is closer to the sheet 6 than the first foreign object exhaust shell 13, and the second static eliminator 14 is closer to the sheet 6 than the first static eliminator 12. By shortening the distance, the static elimination effect is increased, the adsorption strength is improved, and the foreign object is prevented from being adsorbed too firmly and not being sucked away at once.
[0022] In this embodiment, the negative pressure ionization device 1 is fixed above the sheet 6 on the production line, so that the air outlets of the first foreign object extraction shell 13 and the second foreign object extraction shell 15 are facing the sheet 6. One side of the scraper 5 is in slight contact with the sheet 6. During dust removal, the fan 2, the first static eliminator 12 and the second static eliminator 14 are started. The first static eliminator 12 and the second static eliminator 14 eliminate the static electricity on the sheet 6 below them. The fan 2 causes the negative pressure generating cylinder 11 to generate negative pressure, which sucks the foreign objects located near the first foreign object extraction shell 13 and the second foreign object extraction shell 15 into the ionization dust collector 3.
[0023] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
