Description

Technical Field

[0001] This utility model relates to the technical field of printing roller grinding machines, and specifically to a grinding head mechanism for printing roller grinding machines. Background Technology

[0002] A printing roller grinding machine is an important piece of equipment used in the printing industry. It is mainly used to precisely grind the surface of printing rollers and repair worn or damaged rollers, as well as adjust the roundness and concentricity of the rollers to ensure the smoothness and precision of the roller surface.

[0003] The existing flatbed printing roller grinding machines rely on springs and proximity switches for pressure control, resulting in coarse and inaccurate pressure adjustment. This places high demands on the operator's experience and skill level, leading to inconsistent surface finish of the printing roller. Furthermore, the grinding pressure is fixed and unadjustable during both coarse and fine grinding. Specifically, the grinding head pressure is applied via springs, and pressure adjustment relies on adjusting the distance of a sensor switch to control the spring's preload and mechanical displacement. This method is difficult to precisely control. Simultaneously, the proximity switch only detects position and cannot provide real-time feedback or dynamic pressure adjustment, causing unstable pressure variations during processing and affecting the grinding effect. Since pressure adjustment depends on manual experience, operators need to constantly experiment and adjust to achieve the appropriate processing state. This not only increases the skill requirements for operators but also increases the possibility of inconsistent grinding pressure control due to human error, resulting in fluctuations in processing quality. The inaccurate pressure control can lead to over-grinding or under-grinding during the grinding process, making it difficult to maintain consistent surface flatness and roughness, affecting subsequent printing quality. In addition, pressure variations can cause uneven stress on the printing roller surface, resulting in surface defects or uneven wear. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a grinding head mechanism for a printing roller grinding machine, which achieves precise control of the grinding head pressure, effectively improving processing accuracy and product quality, as well as increasing production efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a grinding head mechanism for a printing roller grinding machine, comprising a grinding head base, a power sleeve rotatably connected to the grinding head base, a grinding stone disc connected to one end of the power sleeve, a first power wheel fitted to the other end of the power sleeve, the power sleeve being hollow inside and having a through shaft, a connecting shaft connected to one end of the through shaft, the connecting shaft being connected to the output end of a cylinder, the other end of the through shaft being rotatably connected to the grinding stone disc, and a motor also being provided on the grinding head base, the first power wheel being drively connected to the output end of the motor.

[0006] As a further embodiment of this utility model: a plurality of first bearings are spaced apart on the outer side of the power sleeve, and the power sleeve is rotatably connected to the grinding head seat through the first bearings.
