Description

An automatic detection and calibration device for the eccentricity of printing rollers Technical Field

[0001] This utility model relates to the field of printing rubber roller detection and calibration technology, and in particular to an automatic detection and calibration device for the eccentricity of printing rubber rollers. Background Technology

[0002] Printing rollers, divided into hard rollers and soft rollers, are used in printing machinery for printing, ink mixing and ink transfer. These rollers have moderate hardness and elasticity, high oil resistance, solvent resistance, wear resistance and shape stability. During operation, printing rollers often experience wear and other phenomena. In order to achieve good working results, the surface of printing rollers needs to be inspected.

[0003] A search revealed Chinese Patent Publication No. CN213238863U, which discloses a device for detecting the surface flatness of a rubber roller. The device includes a support base with support frames installed at both ends of the top surface of the base. A support hanging plate is fixed to the inner side of the middle of the top surface of the support frames, and an electric slide rail is installed at the bottom of the support hanging plate. In use, this device moves the detection instrument via a drive mechanism to detect the surface of the rubber roller. However, this detection device is not easily adjustable according to the size and specifications of the printing rubber roller, resulting in poor applicability. Furthermore, it only involves placing and driving the rubber roller, leading to poor stability and potential errors in the detection results, thus failing to meet usage requirements. Therefore, an automatic detection and calibration device for the eccentricity of printing rubber rollers is proposed to solve the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic detection and calibration device for the eccentricity of printing rollers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic detection and calibration device for the eccentricity of printing rollers includes a calibration platform. The top of the calibration platform is provided with an adjustment groove. The top of the calibration platform is provided with two mounting grooves located in front of the adjustment groove. The mounting grooves are provided with a clamping and positioning mechanism extending to their tops. The adjustment grooves are provided with a detection mechanism extending to their tops. The detection mechanism is provided with a calibration and polishing mechanism in front of its front side.

[0007] The clamping and positioning mechanism includes two support blocks, each movably mounted inside a different mounting slot.

[0010] Preferably, the calibration and polishing mechanism includes a fixed frame, which is fixedly installed on the top of the adjusting block and located on the front side of the mounting frame. A fixed plate is fixedly installed inside the fixed frame, and a fourth motor is fixedly installed at the bottom of the fixed plate. The output shaft of the fourth motor passes through the fixed plate and is fixedly connected to a third screw. A threaded sleeve extending to the top of the third screw is threaded on its outer side.

A fourth motor drives a third screw to rotate, causing a threaded sleeve to extend and retract the connecting frame and grinding roller. The drive motor synchronously controls the rotation of the grinding roller, dynamically grinding and calibrating any detected uneven eccentric areas. This effectively helps users adjust and calibrate printing rollers of different sizes, improving the equipment's applicability. Attached Figure Description

[0027] Example

[0028] As shown in Figures 1-4, this utility model provides a technical solution: an automatic detection and calibration device for the eccentricity of printing rubber rollers, including a calibration platform 1.

This automatic detection and calibration equipment for the eccentricity of printing rubber rollers, through the coordinated work of the detection mechanism 5 and the calibration grinding mechanism 6, drives the second screw 51 to rotate, causing the adjusting block 53 to move along the adjusting groove 2. The electric telescopic rod 55 adjusts the vertical height of the detector 57, realizing full-dimensional detection of the circumferential surface of the rubber roller.

This effectively helps users adjust and calibrate printing rubber rollers of different specifications and sizes, improving the applicability of the equipment.

[0033] The working process of this utility model:

[0034] Step 1: By controlling the start of the first motor 44, the first screw 43 is driven to rotate, which drives the two support blocks 41 to move laterally along the mounting groove 3. The distance between the two four-jaw chucks 47 is adjusted to match the length of the rubber roller shaft. At the same time, the positioning and fixing are completed by the four-jaw chucks 47. The second motor 471 on the right mounting block 45 synchronously drives the corresponding rotating shaft 46 to rotate, ensuring that the rubber roller rotates synchronously with the rotating shaft 46.

[0035] Step 2: By controlling the start of the third motor 52 to drive the second screw 51 to rotate, the adjusting block 53 can move longitudinally along the adjusting groove 2, thereby adjusting the transverse detection position of the detector 57. The electric telescopic rod 55 can adjust the vertical height of the detector 57 so that it can detect the surface of the rubber roller according to its specifications. When the rubber roller rotates at a constant speed, the detector 57 detects the circumference of the rubber roller surface.

[0036] Step 3: By controlling the start of the fourth motor 63 to drive the third screw 64 to rotate, the threaded sleeve 65 drives the connecting frame 66 and the grinding roller 67 to extend and retract to fit the printing roller; the drive motor 671 controls the rotation of the grinding roller 67 to grind and calibrate the uneven and eccentric parts.
