Description

Technical Field

[0001] This utility model relates to the field of printing technology, specifically to a printing roller lateral movement mechanism based on a ball screw to prevent water ingress through a proximity switch. Background Technology

[0002] Printing refers to the process of transferring graphic information from an original artwork onto a substrate using a printing plate or other methods. It involves using analog or digital image carriers to transfer colorants and pigments onto the substrate. In the printing process, the printing roller is the main component, and the printing roller traversing mechanism is a crucial part for ensuring printing quality and efficiency.

[0003] The proximity switches in existing transverse movement mechanisms are susceptible to corrosion from liquids in the working environment. Existing proximity switch installation methods lack effective protection against liquid intrusion, leading to shortened switch lifespan and increased equipment maintenance costs and downtime. Therefore, this paper proposes a water-resistant proximity switch-based transverse movement mechanism for printing rollers using a ball screw. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides a printing roller lateral movement mechanism based on a ball screw to prevent water ingress through a proximity switch. It offers the following advantages:

[0018] (i) The printing roller lateral movement mechanism based on a ball screw and a proximity switch for preventing water ingress has a lateral movement mechanism installed inside the lateral movement sleeve and fixed by a mounting bracket. This effectively prevents water or other liquids from corroding the proximity switch, improving its service life and stability, and ensuring the normal operation of the lateral movement mechanism. On the other hand, the proximity switch in the detection unit consists of a transmitter and a receiver, which are placed on both sides of the detection plate. This allows for accurate detection of the lateral movement position of the printing roller, precise control of the lateral movement stroke, and improvement of printing accuracy and quality. At the same time, the lateral movement sleeve is connected to the frame through a bearing seat and a rotating shaft, and the slide rail cooperates with the limit block to provide precise guidance and reliable limit for the movement of the lateral movement sleeve, reducing the shaking and offset of the printing roller during lateral movement and ensuring lateral movement stability.

[0019] (II) The printing roller lateral movement mechanism based on a ball screw and a proximity switch for preventing water ingress has a drive mechanism that uses a transmission method in which the first bevel gear at the motor output end meshes with the second bevel gear on the screw. This mechanism has a compact structure, high power transmission efficiency, and can provide stable power for the translation mechanism, ensuring smooth and reliable lateral movement of the printing roller. The motor is fixed by a fixing plate, and the connecting frame and drive box ensure a stable connection between the motor output end and the screw, ensuring stable motor operation and thus providing stable power output to guarantee the smoothness of the lateral movement process. Furthermore, by controlling the motor operation, the rotation speed and direction of the screw can be easily adjusted, achieving precise control of the lateral movement speed and direction of the printing roller to meet the needs of different printing processes.
