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 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 plate, the small circle and the dotted line are added.

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, the center of the four small circles on the dial coincides with the dotted line formed when the vibration direction is vibrating as a straight line (i.e., the vibration direction line, see Figure VII.a), at which point, the small circle coincides with the vibrational direction angle line on the dial by indicating that the center of the disc "O" is perpendicular to the vibrational direction line on the dial, i.e. the vibration direction angle is greater than the angle indicated by the indicator plate

5. use and adjustment of indicator board<br>① Indication principle of vibration direction angle (see Fig. 6)<br>The included angle θ between the vibration direction line and the vibration table line of the vibration motor is called the vibration direction angle. The scale of 20-60 on the indicator plate indicates the value of the vibration direction angle. During operation, the center of four small circles on the indicator plate coincides with the dotted line formed during vibration along the vibration direction (i.e. vibration direction line, see Fig. 7.a). At this time, the center of the four small circles on the indicator plate coincides with the dotted line formed during vibration (i.e. vibration direction line, see Fig. 7.A), The scale value of the line perpendicular to the vibration table line through the center of the indicator disk "O" coincides with the scale line of the vibration direction angle on the scale plate, that is, the value of the vibration direction angle. If the vibration direction angle is greater than the angle indicated by the indicator, the small circle and dotted line shall be added<br>
