Description

Technical Field

[0001] This utility model belongs to the technical field of screw cleaning machines, specifically a fully automatic screw cleaning machine. Background Technology

[0002] As the core equipment in printing production, the performance and efficiency of a printing press directly affect the quality and output of printed products. The printing press screw plays a crucial role in the printing process, ensuring the even distribution of ink onto the printing cylinder and guaranteeing the consistency and clarity of the printed product's colors. In high-speed printing presses, precise ink supply from the screw is essential for improving printing efficiency and quality, meeting the ever-growing demands of the printed market.

[0003] During printing press operation, a large amount of ink inevitably adheres to the surface of the screw. Over time, this ink buildup affects print quality. Current technology typically involves manual cleaning of the printing press screw, which is inefficient, time-consuming, and labor-intensive. Furthermore, it's difficult to clean the screw's tiny crevices and corners, leading to ink residue and inconsistent cleaning results, thus impacting subsequent print quality. In addition, manual cleaning can damage the screw due to improper operation, shortening its lifespan and increasing the printing press's maintenance costs. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model is equipped with a cleaning component. In use, the first drive motor drives the rotating shaft to rotate, causing the paddle to rotate at high speed inside the first and second sealing blocks, generating suction to draw water from the water tank and spray it onto the screw body through the spray pipe and spray head for water washing. This can achieve automated water washing, which greatly improves the cleaning efficiency compared to manual cleaning. Moreover, through the stirring of the paddle and the spray of water, the screw surface can be cleaned more comprehensively and thoroughly, ensuring the cleaning effect and avoiding ink residue.

[0017] This utility model is equipped with a cleaning component. During use, the air intake hood draws in air, which enters the jet pipe through the exhaust pipe. At the same time, the first drive motor drives the paddle to rotate, generating suction inside the first and second sealing blocks. This accelerates the air in the jet pipe and causes it to be ejected from the jet head to air dry the screw body after water washing. This can quickly dry the screw after water washing, preventing rust and corrosion caused by residual moisture, and extending the service life of the screw. Furthermore, the automated air drying process is closely integrated with the water washing process, further improving the overall cleaning efficiency.

[0018] This utility model is equipped with a support assembly, a second drive motor, a first gear, and a second gear. In use, four arc-shaped mounting blocks and multiple rollers cooperate to stably support the screw body from multiple directions. The second drive motor drives the first gear to rotate, and through meshing with the second gear, it causes the connecting shaft and rollers to rotate, thereby driving the screw body to rotate. This ensures the stability of the screw during the cleaning process, avoiding the impact of shaking on the cleaning effect. Moreover, the rotation of the screw allows for more thorough water washing and air drying, ensuring that all parts of the screw are fully cleaned and dried, improving cleaning efficiency and effect, and saving time and effort.

The second drive motor 7 drives the connecting shaft 9 and the roller 302 to rotate through the meshing of the first gear 8 and the second gear 10, thereby driving the screw body 4 to rotate. Figure 6 Its transmission structure and connection relationship can be seen in the diagram.

[0040] In another embodiment of this utility model, please refer to Figures 1 to 6 The rear end of the water tank 1 is fixedly connected to a protective cover 6. The second drive motor 7, the first gear 8, the connecting shaft 9, and the second gear 10 are all located inside the protective cover 6. The protective cover 6 is used to protect the second drive motor 7, the first gear 8, and other components from damage caused by external factors.

[0041] In another embodiment of this utility model, please refer to Figure 3 A first baffle 101 is fixedly installed inside the water tank 1. There are two symmetrically distributed first baffles 101. A second baffle 102 is fixedly connected inside the water tank 1. The second baffle 102 is located on top of the two first baffles 101. The first baffles 101 and the second baffle 102 are used to allow the ink washed off the screw body 4 to adhere to the first baffles 101 and the second baffle 102, so as to prevent the ink from entering the water tank 1.

[0042] In another embodiment of this utility model, please refer to Figures 1 to 3 The cover 2 has a slot inside, and an observation glass 201 is embedded in the inner wall of the slot. A handle 202 is fixedly installed on the outer wall of the cover 2. The observation glass 201 facilitates observation of the cleaning process, and the handle 202 facilitates opening and closing the cover 2.

[0043] In another embodiment of this utility model, please refer to Figures 1 to 3 The bottom of the water tank 1 is fixedly connected to a support leg 11.

[0044] Working principle: First, the screw body 4 to be cleaned is placed on the support assembly 3. The outer wall of the screw body 4 is in contact with multiple rollers 302. Four arc-shaped mounting blocks 301 cooperate with the rollers 302 to support the screw body 4 from multiple points.

[0045] Then, after closing the cover 2, the first drive motor 505 is started. The first drive motor 505 drives the rotating shaft 503 to rotate, and the blades 504 on the rotating shaft 503 rotate at high speed. As the blades 504 rotate inside the first sealing block 501 and the second sealing block 502, they generate suction, which draws water out of the water tank 1 through the water inlet pipe 506. The drawn water passes through the water outlet pipe 507 and enters the water spray pipe 508. Finally, it is sprayed out through multiple water spray heads 509, evenly sprayed onto the screw body 4, to achieve water washing of the screw.

[0046] Next, the second drive motor 7 is started, which drives the first gear 8 at the output end to rotate. The first gear 8 meshes with the second gear 10, which in turn drives the connecting shaft 9 and the roller 302 to rotate. When the roller 302 rotates, it drives the screw body 4 to rotate synchronously, so that all parts of the screw surface can be fully washed by water.

[0047] After the water washing is completed, the first drive motor 505 is started, which drives the paddle 504 to rotate. This generates suction inside the first sealing block 501 and the second sealing block 502, which accelerates the air in the jet pipe 512 and sprays it out from multiple jet nozzles 513 to perform an air blowing operation on the water-washed screw body 4, so that the screw dries quickly.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
