Description

Technical Field

[0001] The present application relates to the field of rotary presses, and in particular to a dust removal device for a rotary press. Background Art

[0002] A rotary printing press is a professional printing device, usually used for large-scale, high-speed, and continuous printing production. It is a printing technology suitable for printing large quantities of printed materials such as newspapers, magazines, books, advertising sheets, packaging materials, etc. By introducing the printing material (such as paper, film, etc.) from a large reel, passing through a series of printing units, and finally winding it into a printed product. During the printing process of the substrate, the surface quality of the printed matter is often affected because the substrate surface carries dust. Therefore, an electrostatic dust collector is generally set in the rotary press to absorb the dust attached to the substrate surface through a dust collection plate.

[0003] Since the electrostatic dust collector usually accumulates a layer of dust on the dust collection plate or dust collection pipe, in order to maintain its efficient operation, it is necessary to regularly remove this accumulated dust. Generally, the dust collection plate is removed from the electrostatic dust collector for cleaning. However, the rotary press needs to operate continuously, and cleaning the dust collection plate will affect the dust removal effect on the substrate surface, thereby having a certain impact on the overall use efficiency of the rotary press and reducing the overall printing efficiency of the substrate.

[0004] In view of the above-related technologies, the inventor believes that there is a defect that the dust collection plate is not easy to clean when the rotary printing press performs electrostatic dust removal on the substrate. Therefore, a dust removal device for a rotary press is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to solve the problem that the dust collection plate is not easy to clean when the rotary printing press performs electrostatic dust removal on the substrate, the present application provides a dust removal device for a rotary press.

[0006] The dust removal device for a rotary press provided by the present application adopts the following technical solutions:

[0007] A dust removal device for a rotary press, including a rotary printing press, on the upper surface of which a printing substrate is movably conveyed. Above the printing substrate on the upper surface of the rotary printing press, a number of electrostatic dust collection plates are symmetrically and movably installed. In the middle of the top of the rotary printing press, a support frame is fixedly installed. On both side parts of the support frame, connecting plates are symmetrically welded. On one side of the connecting plate above the electrostatic dust collection plate, a fixed frame is welded. On the upper surface of the support frame, a fixed plate is movably installed. On both sides of the fixed plate, connecting rods are symmetrically welded. On one side of the two connecting rods on the same side, which extends into the fixed frame, a dust removal box is welded. In the middle of the bottom end of the dust removal box, a dust scraping plate is fixedly installed. At the front and rear ends of the bottom end of the dust removal box near the dust scraping plate, dust suction openings are opened. At the inner top of the dust suction opening, a dust suction fan is installed. On the upper surface of the rotary printing press, a rotating mechanism is also provided for adjusting the position transformation of multiple electrostatic dust collection plates.

[0008] Preferably, the rotating mechanism includes fixed support plates, which are symmetrically welded at the edge parts of the upper surface of the rotary printing press. Between the two front and rear symmetric fixed support plates, a support rotating shaft is rotatably installed. A number of electrostatic dust collection plates are fixedly connected at equal intervals on the outer surface of the support rotating shaft. One end of the support rotating shaft extends outside the fixed support plate and is provided with a rotating handle.

[0009] Preferably, a dust collection box is installed on the upper surface of the dust removal box. In the middle of the top end of the dust collection box, a square opening is penetrated. In the square opening on the upper surface of the dust collection box, a dust filter net is installed.

[0010] Preferably, on both sides of the top end of the dust removal box, limit clamping plates are welded. On both side parts of the bottom end of the dust collection box, sealing clamping strips are welded. The sealing clamping strips are located inside the limit clamping plates, and the limit clamping plates and the sealing clamping strips are mutually clamped.

[0011] Preferably, in the middle of the top end of the support frame, a guiding sliding groove is penetrated. The bottom end of the fixed plate extends into the guiding sliding groove and is fixedly connected with a sliding block. The guiding sliding groove and the sliding block are mutually embedded.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. Through the electrostatic dust collection plates, electrostatic dust removal is carried out on the printing substrate passing below. Rotate the rotating handle to adjust the electrostatic dust collection plates at different positions for use, so that the electrostatic dust collection plates filled with dust are placed directly below the fixed frame. At the same time, push the fixed plate to reciprocate along the upper surface of the support frame, so that the dust removal box drives the dust scraping plate to scrape the dust filled on the electrostatic dust collection plates; compared with the prior art, this solution has the effect of facilitating the convenient cleaning of the dust collected on the electrostatic dust collection plates, improving the continuous dust removal effect of the electrostatic dust collection plates on the printing substrate, solving the problem that the cleaning of the electrostatic dust collection plates after a certain period of use affects the dust removal efficiency before printing the printing substrate, and improving the overall use efficiency of the rotary printing press.

[0014] 2. The dust sucked by the dust suction fan through the dust suction port is absorbed, so that the dust enters the interior of the dust removal box and is conveyed into the dust collection box. The limit clamping plate and the sealing strip cooperate to keep the dust collection box sealed on the upper surface of the dust removal box. The dust filtering net filters the dust and keeps the interior of the dust collection box ventilated. This solution has the effect of facilitating the collection of the dust scraped by the dust scraping plate, avoiding the problem of dust scattering into the environment after being scraped out, and improving the overall dust collection efficiency of the dust removal box and the dust collection box.
