Description

Laser type milk box edging polisher Technical Field The invention relates to the technical field of cutting flash, in particular to a laser type milk box trimming and grinding machine. Background In the blow molding process of the plastic milk box, due to the influence of factors such as mold closing clearance, material flowing state, molding shrinkage and the like, a mold closing line area of the outer wall of the milk box often forms a certain degree of flash. In order to ensure the appearance quality and assembly suitability of the product, the flash is usually subjected to subsequent treatment on the production line. However, in actual processing, the milk box has a thin shape and a certain elasticity, so that the relative position of the flash is unstable due to the deviation of the posture during clamping, thereby influencing the accuracy of the trimming process. In addition, the traditional edging mode is mostly dependent on fixed cutters or simple visual positioning, and when the position of a workpiece is slightly deviated, the cutting consistency and continuity of a edging area are easily affected, so that the appearance quality and the machining efficiency are further affected. Therefore, in the downstream edging process, how to reliably position the milk box in the clamping stage and accurately mark the edging position before cutting so that the subsequent cutting end can execute accurate edging, thereby obtaining more stable processing quality is a technical requirement of general attention in the industry. According to the requirements, by arranging the workpiece jig capable of being finely adjusted and the detection assembly capable of calibrating the space position of the flash in advance, the subsequent laser trimming can be precisely processed according to the calibration result, so that the trimming efficiency and consistency are improved. Thus, a laser milk carton trimming grinder is provided for the above-mentioned problems. Disclosure of Invention The invention provides a laser type milk box edging polisher for solving the problems that a blow-molded milk box is unstable in edging position and insufficient in traditional edging precision and consistency. The invention solves the technical problems by the following technical proposal: the invention provides a laser type milk box edging and grinding machine which comprises a frame, wherein the frame comprises a workbench, the surface and the top of the workbench are sleeved with an outer frame, the outer frame is fixedly connected with the workbench, a rotatable dividing plate is arranged on the workbench, and a plurality of jigs which are used for placing milk boxes and distributed in an annular array are arranged on the surface of the dividing plate; A working table at one side of the dividing plate is provided with a calibration assembly and a edging assembly with a laser cutting head, and the direction from the calibration assembly to one side of the edging assembly is the autorotation direction of the dividing plate; the jig comprises a positioning unit for positioning the milk box and a calibration limiting unit capable of finely adjusting the position of the milk box, and the positioning unit and the calibration limiting unit are clamped at two sides of the milk box; the bottom between the locating unit and the calibration limiting unit is provided with a locating plate, and the locating plate is fixed on the surface of the index plate. The output end of the driving motor is fixed at the center of the bottom end of the dividing disc, and the driving motor is fixed on the surface of the workbench. According to the invention, the milk box is initially positioned by the positioning unit, and the posture of the milk box is finely adjusted by the calibration limiting unit, so that the outer walls of which the two sides are easy to generate flash are in a vertical state. When the dividing disc rotates, the clamped milk box sequentially passes through the calibration assembly and the edging assembly, wherein the calibration assembly is used for identifying the position of the edging on the surface of the milk box, and the edging assembly precisely removes the edging by using the laser cutting head, so that a polishing-like treatment effect is realized. By means of the jig capable of being finely adjusted and the calibration assembly capable of calibrating the flash position in advance, the overall cutting efficiency can be remarkably improved. In the technical scheme, the calibration assembly and the edging assembly extend to the top area of the index plate and are positioned right above the passing jig along with the rotation of the index plate; the central angle between the center of the action end of the calibration component and the center of the action end of the edging component on the wind-force disc is consistent with the central angle between two adjacent jigs on the index disc.
