Common problems and solutions to the use of belt
1 machine running belt creping, tear, deviation
Check whether the right -- belt circumference;
Check whether the belt -- cylindricity is too large;
Check whether the twisted belt --. A simple method of examination: the belt laid flat in a flat, abrasive belt
Side alignment, see if the other side is twisted;
-- check the belt machine contact wheel, whether foreign graphite pad and workpiece grinding board;
- check the amount of the work piece to meet the requirements.
2 belt plug in the grinding process
-- mostly occurs at the high oil content of wood particleboard, abrasive belt in grinding of these plates and the sawdust is easy to stick on the sand surface, the surface sand jam, lose the ability of grinding, and then burnt, this is generally the large surface area of the whole belt;
-- in particleboard production process, due to the uneven mixing, the resin adhesive in certain parts of the sand surface, resulting in belt partial blockage of the bond, the general to the local strip appeared;
In addition, belt machine in the grinding process, bits of wood are not drawn dust flow away, on the sand surface forming a thin layer of, linear sawdust intermittent flow, the chips of belt of commonly used has little effect.
3 the machined surface of the plate has a vibrating groove and a groove
-- check the thickness of belt joints. Using micrometer to check belt joint thickness and belt substrate thickness average difference, the difference between general control less than 0.10 mm;
-- check the belt machine contact wheel, whether a foreign body belt surface, such as sand group;
In general, the belt is mainly caused by the foreign body surface groove.
