Description

Technical Field

[0001] The utility model relates to the technical field of roundness detection, in particular to a roundness detection device for a liquid removal roller. Background Art

[0002] As a key component in many industrial production lines, the de-liquidating roller's primary function is to remove excess liquid from the surface of the substrate or substrate to achieve uniform coating or drying, among other subsequent process requirements. However, during the manufacturing, use, and maintenance of de-liquidating rollers, their roundness can easily deviate due to factors such as material unevenness, processing errors, and long-term wear. De-liquidating rollers with poor roundness can lead to uneven liquid coating thickness during operation, causing product quality issues such as inconsistent printed color and fluctuating coating layer thickness. Furthermore, they can exacerbate wear on the de-liquidating roller and surrounding components, shortening equipment life and increasing production costs and maintenance frequency. Therefore, the de-liquidating roller's roundness needs to be tested.

[0003] The existing measurement method is to indirectly evaluate the roundness by measuring the diameter of the roller at different positions with a caliper. In order to make the detection data more comprehensive, the measurement personnel need to perform multiple measurements at different positions on the surface of the de-liquidating roller. The entire detection process of the de-liquidating roller roundness is time-consuming and inconvenient. Utility Model Content

[0009] A further improvement of the technical solution of the present invention is that: a second mounting plate is engaged with one end of the liquid removal roller, and one side of the second mounting plate is rotatably connected to one side of another mounting bracket.

[0010] A further improvement of the technical solution of the present utility model is that a handle is rotatably connected to the interior of the mounting frame, and one end of the handle is fixedly connected to the interior of the second mounting plate.

[0011] A further improvement of the technical solution of the present utility model is that the display mechanism includes a connecting member, one end of the connecting member is fixedly connected to the surface of the sliding block, and one end of the connecting member is rotatably connected to an arc-shaped scribing plate.

[0015] The utility model provides a device for detecting the roundness of a dewatering roller. Through the setting of a detection mechanism, when measuring the roundness of the dewatering roller, the dewatering roller is rotated to rotate along the axis. If there is a raised portion on the surface of the dewatering roller, the raised portion pushes the detection part to rotate during the rotation process, so that the marking pen draws lines on the surface of the arc marking plate. If there is a recessed portion, similarly, under the action of the thrust of a first spring, the detection part is also rotated, thereby drawing lines on the surface of the arc marking plate. The shorter the line, the rounder the roundness of the dewatering roller. According to the length of the line, the roundness of the dewatering roller can be obtained, making detection more convenient. The setting of multiple detection parts and marking pens can simultaneously detect different positions on the surface of the dewatering roller. Compared with conventional detection methods, the detection speed is faster. BRIEF DESCRIPTION OF THE DRAWINGS
