Maintenance of belt sanding machine

1. The gear pair, worm gear pair, lead screw nut mechanism, guide rail pair and all bearings on the sander shall be lubricated regularly according to the lubrication requirements. During lubrication, clean the nozzle with a brush without sundries. When lubricating the bearing with grease, the filling amount of grease should be appropriate. Generally, the filling amount should account for 1 / 3 or 1 / 2 of the space between the bearing and the shell. The bearing lubrication should be carried out when the machine tool is stationary. After lubrication, rotate by hand for several minutes to balance the grease in the bearing. Do not start the machine tool at high speed immediately.

2. The sundries and dust on and around the machine tool shall be removed after the work on duty. Prevent them from accumulating in the equipment and avoid the problem of heat dissipation of the sander affecting the equipment.

3. Grind the maintenance conveyor belt of the plane sander, raise the sanding pad, adjust the level of the workbench, start the sander and the conveyor belt to lift the workbench until the workbench gently touches the sanding belt. The grinding amount of the conveyor belt shall not be greater than 0.1mm each time to avoid heating and deformation of the conveyor belt. After adjustment, remove the wear debris and set the thickness to zero.

4. Regularly grind the thickness fixing roller, adjust the level of the worktable, remove the sand belt, put a template with 60~80 sandpaper pasted on the surface of the thickness fixing sanding on the conveyor belt, under the thickness fixing roller, the template width shall reach a certain width value, start the thickness fixing roller motor, raise the worktable, make the sandpaper gently touch the roller, and move the template back and forth along the length of the steel roller, stably After adjustment with constant speed and no stay, remove the wear debris and set the thickness to zero.

5. Adjust the pressing roller, raise the sanding pad, remove the sanding belt, raise the workbench, make the thickness fixing roller gently contact the conveyor belt, then lower the workbench by 1mm according to the thickness display reading, loosen the nuts at both ends of the pressing roller until the pressing roller gently contacts the conveyor belt, and tighten the nuts.

6. Level the sand pad, lift the sanding pad, remove the sand belt, place a small level on the conveyor belt, raise the workbench until the thickness fixing roller gently contacts the level, lower the sand pad gently contacts the level, move the level from one end of the sand pad to the other end, check the levelness of the sand pad, and adjust it through the left and right threads of the sanding pad if there is any error.

7. Check the air filter every week to remove the condensate.

8. Regularly check the maintenance feeding of the plane sander and the tension of the lifting drive chain, and tighten it if necessary.
