Description

A roller support device for saw grinding machine

Technical Field

The utility model belongs to the technical field of saw grinding machines, in particular to a roller supporting device for saw grinding machines.

Background technique

At present, in the process of plate processing, it is often necessary to cut the plate. Band saw blades are widely used as commonly used saw blades. The long-term use of band saw blades is more seriously worn. Continuing to use is likely to make the cutting accuracy low and the error large. A saw grinder is often used to sharpen it again. The commonly used saw grinder drives the grinding wheel to grind the saw blade through a motor. When the band saw blade is ground, the band saw blade is guided and fixed by rollers and pressure rollers. The rollers are usually fixed on the roller brackets. The roller brackets can be adjusted up and down for blades of different sizes on the saw grinder. A sliding groove is opened on the roller bracket of the commonly used saw grinder. The roller is limited by a limit rod fixed on the saw grinder, and the roller is fixed by a fixing nut on the limit rod. The sliding groove is vertically opened on the bracket. When adjusting the height, after unscrewing the fixing nut, in order to prevent the bracket from sliding down too fast, the personnel need to hold the bracket in advance, and the height of the bracket is adjusted by the operator pushing the bracket up and down. The adjustment accuracy is difficult to control, and the operator's energy is also consumed, and the use effect is not good.

After searching, the authorization announcement number CN208825731U and the authorization announcement date 2019.05.07 disclose a roller bracket of an alloy saw blade sharpening machine. A roller body bracket for adjusting the height of the roller through a threaded matching relationship is disclosed. The structure is simple, convenient and practical, and can effectively improve the accuracy of adjusting the height of the roller body. The main frame is composed of a cross bar and two vertical bars, and the two vertical bars are respectively vertically arranged at the two ends of the cross bar, and the two vertical bars of the main frame are respectively provided with mounting grooves at one end, and the roller body is placed in the mounting groove, and one end of the two rotating rods is respectively placed on both sides of the roller body, and the other end is respectively placed on the main frame through fixed bearings, and a fixed groove is opened on the outside of the roller body, and the fixed groove is an annular groove, one end of the two sliding rods is respectively vertically placed on the cross bar of the main frame, a limit block is placed on the other end of the sliding rod, a sliding sleeve is placed on the sliding rod, a connecting rod is placed on the sliding sleeve on the sliding rod, and a fixed spring sleeve is placed on the sliding rod and is located between the sliding sleeve and the limit block.
