5.指示牌的使用和调整①振动方向角指示原理（见图六）振动电机的振动方向

5. Use and adjustment of the sign <br>① The principle of indicating the direction of vibration (see Figure 6) <br>The angle θ between the vibration direction line of the vibrating motor and the surface line of the vibrating table is called the vibration direction angle, and the 20-60 scale on the indicator plate indicates vibration The direction angle value. When working, the center of the four small circles on the indicator disk coincides with the dashed line formed during vibration along the vibration direction as a straight line (that is, the vibration direction line, see Figure VII.a). At this time, the center "O" of the indicator disk is perpendicular to The scale value where the straight line on the surface line of the vibrating table coincides with the scale line of the vibration direction angle on the scale is the value of the vibration direction angle. If the vibration direction angle is greater than the angle indicated by the indicator disc, the small circle and the dotted line will cross move. (As shown in b and c in Figure 7), the screw at the center of the dial should be loosened at this time to adjust.

5. Use and adjustment of signage<br>(1) The principle of vibration direction angle indication (see Figure 6)<br>The angle between the vibration direction line of the vibration motor and the vibration table line is called the vibration direction angle, and the scale of 20 to 60 on the indicator plate indicates the value of the vibration direction angle. When working, indicate that the center of the four small circles on the disk coincides with the dotted line formed when the vibration is in the direction of vibration (i.e., the direction line of vibration, See Figure VII.a), at this point, by indicating that the disc center "O" perpendicular to the vibration table line of the line coincides with the vibration direction angle tick mark on the dial, that is, the vibration direction angle value, if the vibration direction angle is greater than the angle indicated by the dashboard, the small circle and dashed line to do cross-motion (as shown in Figure VII b, c), should release the screw at the center of the dial circle to make adjustments.

5. Use and adjustment of signs<br>① Indication principle of vibration direction angle (see Figure 6)<br>The angle θ between the vibration direction line of the vibration motor and the vibration table line is called the vibration direction angle, and the 20-60 scale on the indicator plate indicates the value of the vibration direction angle. During operation, the centers of the four small circles on the indicator disk coincide with the dotted line formed during vibration along the vibration direction to form a straight line (i.e. vibration direction line, see Fig. 7. A), If the vibration direction angle is greater than the angle indicated by the indicator disc, the small circle and the dotted line cross each other (as shown in B and C in Fig. 7). At this time, the screw at the center of the dial should be loosened for adjustment.<br>
