Technical Field

The invention relates to the technical field of back grinding of leather rollers, in particular to a novel drawing leather roller back grinding device.

Background

The leather roller is continuously used for a period of time, under long-term repeated bearing, uneven grooves appear on the surface, so that the common leather roller needs to be ground back (0.2 mm is ground off each time) after being used for one month, so that the eccentric leather roller is reduced, and the roundness of the leather roller is recovered.

Generally, a double-thimble clamping mode is adopted for the drawing leather roller to grind back the drawing leather roller, namely two concave thimbles are adopted to prop against two end faces of a leather roller core, but the requirement on the concave thimbles is extremely high in the condition, namely:

(1) the hole conical surfaces at the centers of two ends of the leather roller core are required to have no jump to the rotating center of the leather roller core;

(2) the jumping quantity of the conical surface of the central hole of the leather roller core is 0 when the double thimbles clamp the leather roller core;

(3) the coaxiality of the axial direction of the core of the leather roller and the axial direction of the thimble of the leather roller grinding machine 1 needs to be ensured;

but the leather roller is at the operation process that actually goes back to grind, it is very difficult to accomplish above-mentioned several points, because the mode of holding additional of two thimbles, the precision requirement to the thimble itself is high, the amount of jump is little, but when the work of leather roller mill, do not have special device to stabilize it, the influence that the amount of jump brought to drawing leather roller grinding can't be got rid of promptly, secondly the precision requirement to leather roller core 2 self centre bore is also high, if there is slight damage or there is a little debris to influence centre gripping precision in the centre bore, finally, in the course of working of thimble and leather roller core, the two machining precision must have certain difference more or less, then must make the leather roller produce the error accumulation in the grinding in-process, the eccentric value exceeds standard promptly. And the core head and the thimble head of the leather roller are easy to wear, so that the leather roller slips when being reground, the rotation of the leather roller becomes slow, the grinding quality becomes poor, and the drawing leather roller can not be used for producing yarns.

Therefore, in order to solve the problems of large eccentric amount and back-grinding slippage of the drawing leather roller during back-grinding, a new drawing leather roller back-grinding device needs to be provided.
