Embodiment 1

[0009] Embodiment 1: with reference to attached Figure 1~3 . The belt automatic deviation correction device of the broadband sander, the shaft 6 of the driven roller 1 adopts the bearing seat 5 to be located on the shaft seat, the bearing seat is located on the driven roller beam 7, and the driven roller beam 7 is located in the shaft hole of the base 13 through the rotating shaft 12 and Rotatable, the hollow sleeve 3 is set on the shaft 6 of the passive roller and there is a gap between the peripheral surface of the shaft 6, the distance between the inner wall of the hollow sleeve 3 and the peripheral surface of the shaft 6 is 0.5 or 1mm or 1.5mm or 2mm or 2.5mm or 3mm or 3.5mm or 4mm or 4.5mm or 5mm. The abrasive belt guide wheel 2 and the hollow sleeve 4 are set on the hollow sleeve 3, the abrasive belt guide wheel 2 can rotate around the hollow sleeve 3, the hollow sleeve 4 is fixedly connected with the hollow sleeve 3, and the bushing 8 is set on the abrasive belt guide...

Embodiment 2

[0010] Embodiment 2: On the basis of Embodiment 1, the method of automatic deviation correction of the abrasive belt of the wide-band sander, the abrasive belt on the passive roller directly generates friction force on the abrasive belt guide wheel, and the friction force of the abrasive belt is located at While the side of the guide wheel and the rollers in the roller seat produce a positive force on the inner wall of the roller seat, the wall of the roller seat produces a reaction force on the roller, thus forcing the roller to drive the abrasive belt guide wheel, and the abrasive belt guide wheel drives the passive roller to correct the abrasive belt The angular displacement of deviation can achieve the purpose of automatic deviation correction.

[0011] The heat insulation method of the driven shaft of the abrasive belt of the broadband sander. The hollow sleeve is supported on the shaft seat by the hollow sleeve seat. The hollow sleeve is the guide wheel shaft and there is...

Abstract

The present invention relates to a deviation-rectifying device of abrasive belt for wide belt grinding machine, its method and driven roller heat-insulating method. The shaft of the driven roller adopts the bearing seat positioned on the shaft seat, and the shaft of the driven roller is covered with hollow sleeve, and spaced between them, the hollow sleeve is covered with abrasive belt guide wheel and hollow sleeve seat, the abrasive belt can be rotated about hollow sleeve, the hollow sleeve seat and hollow sleeve and fixedly connected, and the side surface of abrasive belt guide wheel is equipped with roller, and the roller is positioned in the roller seat. Said invention possesses the following advantages: 1. adrasive belt guide wheel and roller positioned on its side surface and roller seat matehed structure design can effectively implement automatic deviation rectification of belt; 2. adopting hollow sleeve to isolate abrasive belt guide wheel from driven roller to prevent damage to bearing due to abnormal temp.; and 3. stable and reliable work performance, it has no need of maintenance basically.

Description

Technical field: [0001] The invention relates to a belt deviation correction device and method of a wide-band sander and a heat insulation method for a driven roller shaft, belonging to the field of sander component assembly manufacturing. Background technique: [0002] Background technology of the present invention: the existing deviation control structure and method of the abrasive belt of the sander all use photoelectric cells as the signal source for monitoring, and the pneumatic or mechanical mobilization mechanism functions to control the actuator. Its shortcomings: First, the manufacturing cost is high, and the working performance is unstable due to the influence of the working environment, which often causes the belt deviation monitoring to fail and the belt to be scrapped; second, the photoelectric control actuator composed of photoelectric monitoring and its pneumatic or motor is complex , not only the failure rate is high, but also the maintenance is difficult, wh...
