Anti-pressure roller device and adjustment control method of abrasive belt grinder

Abstract

The invention provides an inverted roller device of an abrasive belt grinding machine. The inverted roller device comprises sand rollers provided with abrasive belts , inverted rollers and first lifting mechanisms, wherein the first lifting mechanisms comprise bases and lifting rods which go up and down relative to the bases; each end of each inverted roller is supported by the base of each first lifting mechanism; the inverted rollers and the sand rollers are vertically arranged in parallel, and the inverted rollers are supported by the bases and are contacted with or are far away from the sand rollers. The invention further provides a regulating and controlling method of the inverted rollers of the abrasive belt grinding machine. The first lifting mechanisms drive the inverted rollers to move in the direction close to the sand rollers and send a grinding workpiece from the position far away from the sand rollers to the sand roller grinding position; when the abrasive belt grinding machine is in an abnormal work state, the first lifting mechanisms drive the inverted rollers to move in the direction far away from the sand rollers, so that the grinding workpiece can be separated from the sand rollers; and when an abnormal working condition happens suddenly, the inverted rollers are rapidly separated from the position ground by an abrasive belt, so that the grinding workpiece can be rapidly separated from the abrasive belt, and the surface of the grinding workpiece can be avoided from being damaged.

Description

technical field [0001] The invention relates to an anti-pressure roller device of an abrasive belt grinder and an adjustment and control method for the anti-pressure roller of the abrasive belt grinder. Background technique [0002] In the prior art, the counter pressure roller on the back of the sand roller in the metal single-side sanding grinding equipment is fixed on the conveying table together with the grinding workpiece conveying roller, and the sanding grinding amount is adjusted by lifting the table. In the case of sudden abnormal working conditions such as abrasive belt breakage, abrasive belt deviation, and sudden power failure, it cannot be opened quickly, and the surface quality of the grinding workpiece is easily damaged. When the two ends of the emery roller are worn inconsistently or the thickness of the two ends of the abrasive belt is inconsistent, the phenomenon of inconsistent thickness of the two ends of the ground workpiece after grinding will occur. At...

[0002] In the prior art, the counter pressure roller on the back of the sand roller in the metal single-side sanding grinding equipment is fixed on the conveying table together with the grinding workpiece conveying roller, and the sanding grinding amount is adjusted by lifting the table. In the case of sudden abnormal working conditions such as abrasive belt breakage, abrasive belt deviation, and sudden power failure, it cannot be opened quickly, and the surface quality of the grinding workpiece is easily damaged.

When the wear of both ends of the emery roller is inconsistent or the thickness of the two ends of the abrasive belt is inconsistent, the phenomenon of inconsistent thickness at both ends of the ground workpiece after grinding occurs. At this time, it is difficult to correct this phenomenon by online adjustment of the machine
