Description

Technical Field

[0001] This utility model relates to the field of sheet screen printing technology, and in particular to an automatic dust removal device for sheet screen printing. Background Technology

[0002] In the field of sheet screen printing, quality control of printed materials is paramount. The presence of dust, impurities, and other foreign matter can easily negatively impact printing results, causing white spots, blemishes, and blurred lines, severely affecting product yield. Simultaneously, the cleanliness of the printing material surface affects ink adhesion, thus influencing the durability and longevity of the printed pattern. Furthermore, production efficiency is a key concern for businesses; traditional manual cleaning methods are not only inefficient but also increase downtime, reducing the overall operational efficiency of the production line. Therefore, a device capable of efficiently and automatically removing dust from sheet materials is crucial for improving the quality and production efficiency of sheet screen printing, leading to the development of an automatic dust removal device for sheet screen printing.

[0003] In existing dust removal technologies for sheet screen printing, some methods rely on simple mechanical brush cleaning. The mechanical structure primarily involves a motor driving a brush roller to rotate. The bristles on the roller contact the sheet surface, using the mechanical force of the bristles to sweep away the dust. The technical principle is to use the friction and sweeping motion between the bristles and the sheet surface to separate the dust from the sheet, and then a simple air blowing device blows the swept-away dust away. This method can remove some larger dust particles to a certain extent, but it is ineffective for handling fine dust particles and dust attracted to the sheet surface by electrostatic attraction.

[0004] In existing technologies, simple mechanical brush cleaning methods have significant problems. Relying solely on the mechanical force of the brush bristles for dust removal is ineffective at removing fine dust particles, especially those tightly adhered to the sheet surface due to static electricity. This residual dust can cause defects such as white spots, stains, and unclear lines in the printed pattern during subsequent screen printing, severely impacting the yield rate of printed products. This is precisely the problem addressed in the first benefit of this invention, and therefore, an automatic dust removal device for sheet screen printing is proposed to solve these issues.

Slide 6 and track 8 are used to move the adhesive roller 11 and electrostatic dust removal roller 12. The motor 10 drives the slide 6. 9. Fixture 9 is used to support the adhesive roller 11 and electrostatic dust removal roller 12. A rectangular array of feet 2 is fixedly connected to the bottom of the cabinet 1. The outer wall of the control panel 3 is fixedly connected to the inside of the cabinet 1. The top of the cabinet 1... A platform 14 is fixedly connected.

[0029] Working principle: The printed sheet to be dusted is placed on top of the placement platform 14. The pressure plate 5 flattens and fixes the sheet before it enters the dust removal stage to prevent wrinkles from affecting the dust removal effect. After the sheet enters the dust removal area, the sensor 4 detects the position of the sheet and triggers the equipment to start. The ion fan 13 starts working and generates positive and negative ions through a high-voltage electric field, which are blown onto the surface of the sheet to neutralize the static electricity on the surface and initially remove the dust adsorbed by static electricity. At the same time, the pressure gauge 15 monitors the working air pressure of the ion fan 13 in real time to ensure stable airflow. Driven by the motor 10, the sticky roller 11 and the electrostatic dust removal roller 12 start to rotate. With the help of the pneumatic pressing device linked by the pneumatic connecting rod 7, the sticky roller 11 contacts the surface of the sheet with uniform pressure. The double slide rail 6 ensures that the sticky roller rolls smoothly along the fixed track. The fixing frame 9 ensures that the roller body position is accurate. The sticky material on the surface of the sticky roller 11 adsorbs the residual dust, and the electrostatic dust removal roller 12 further eliminates static electricity and assists in dust adhesion. At the same time, the operator can set parameters through the control panel 3 and monitor the operating status of the equipment in real time. When the dust roller 11 has absorbed a certain amount of dust, the dust paper 11 can be replaced to achieve seamless connection with the screen printing process.
