Description

Technical Field

[0001] This utility model relates to the field of non-oriented silicon steel, specifically to a roller coating machine for non-oriented silicon steel coating liquid. Background Technology

[0002] As a core material in the power and electronics industries, the uniformity, adhesion, and thickness accuracy of the surface coatings (such as insulating coatings and anti-rust coatings) of non-oriented silicon steel directly affect the electromagnetic properties, corrosion resistance, and processing adaptability of the products.

[0003] Non-oriented silicon steel often has residual rolling oil, oxide scale, or dust on its surface. Existing equipment mostly uses simple wiping or alkaline washing for pretreatment, which is difficult to completely remove micro-contaminants. If the surface cleanliness is insufficient, the adhesion between the coating and the substrate will decrease, and coating peeling and blistering are likely to occur during subsequent processing or use, leading to short circuits or corrosion of the silicon steel sheets. The coating curing consistency is also poor. Existing drying systems mostly use single hot air or infrared heating, resulting in uneven temperature distribution and uncontrollable air speed. The drying components are mostly fixed structures, which cannot flexibly adjust the heating power and coverage according to the coating type or production line speed, resulting in poor adaptability. To address this, we propose a non-oriented silicon steel coating liquid roller coating machine. Utility Model Content

[0028] Working Principle: After the equipment is started, the silicon steel coil to be processed is first installed on the silicon steel winding drum 3 on the C-shaped bracket 2 at one end of 1. The free end of the silicon steel sheet is introduced into the machine housing 1 through the guide roller 5. The control module starts the motor 4, driving the guide roller 5 to rotate. Under the power transmission of the guide roller 5, the silicon steel sheet is conveyed at a constant speed along the preset path, passing through the conveying channel formed by the guide roller 5 and the second guide roller 8 in sequence, ensuring a smooth and unbiased conveying process. When the silicon steel sheet runs to the bottom of the plasma cleaner 6, the control module... The silicon steel cleaning structure is triggered, and the plasma cleaner 6 releases plasma to bombard the silicon steel surface, thoroughly removing microscopic contaminants such as rolling oil, oxide scale, and dust, laying the foundation for subsequent coating adhesion. The pre-treated silicon steel sheet is precisely conveyed by guide roller 8 to the coating area between two partitions 9. Upon entering the coating stage, the silicon steel sheet is conveyed between support roller 14 and coating roller 15. Support roller 14 provides stable support for the silicon steel sheet, ensuring close contact between the silicon steel sheet and the upper coating roller 15. Simultaneously, the control module... The coating liquid supply assembly is activated. The coating liquid accumulated at the bottom of the casing 1 is pumped through the coating liquid pipe 10 to the sprayer 11. The sprayer 11, through multiple nozzles 12 mounted on its bottom, evenly sprays the coating liquid onto the surface of the coating roller 15. Subsequently, a scraper 13 fixed inside the casing 1 precisely engages with the side of the coating roller 15 to scrape off excess coating liquid from its surface, ensuring a uniform coating film is formed on the surface of the coating roller 15. Driven by the uniform conveying of the silicon steel sheet, the coating roller 15 moves synchronously... The rotating mechanism evenly transfers the coating liquid film onto the top surface of the silicon steel sheet, completing the coating application. The partition 9 effectively prevents the coating liquid from splashing onto other areas of the equipment. After coating, the silicon steel sheet is conveyed to the drying area by the guide roller 3 16. Multiple guide rollers 3 16, which are equidistantly distributed along a straight line, provide stable support for the silicon steel sheet, ensuring that it remains flat during the drying process. The control module starts the drying assembly, and multiple fans 18 inside the drying box 17 operate synchronously, generating directional airflow to dry and cure the coating on the surface of the silicon steel sheet. If the drying intensity needs to be adjusted according to the coating type or production line speed, the number of drying boxes 17 or their installation position can be flexibly increased or decreased or adjusted by sliding the slider 21 with the inner wall groove 19 of the casing 1 to ensure uniform curing of the coating and avoid problems such as cracking and peeling. After drying and curing, the silicon steel sheet continues to move along the conveying path and is finally conveyed to the silicon steel winding drum 20 on the C-shaped bracket 2 at the other end of the casing 1. The control module starts the motor 7, which drives the silicon steel winding drum 20 to rotate and orderly wind up the dried silicon steel sheet. During the entire operation, the control module coordinates the working status of components such as motor 4, motor 7, plasma cleaner 6, liquid pump, and fan 18 in real time.
