①振动方向角指示原理（见图四）振动电机的振动方向线与振动台面线的夹角α

① Principle of vibration direction angle indication (see Figure 4) <br>The angle α 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 scale of 20 to 60 on the indicator plate indicates the value of the vibration direction angle. When working, the centers of the four small circles on the indicator disk coincide with the dashed line formed during vibration along the vibration direction as a straight line (ie, the vibration direction line, see Figure 5.a). At this time, the center of the indicator disk "O" is vertical 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 plate, the small circle and the dotted line cross move (As shown in b and c in Figure 5), at this time, loosen the screw at the center of the dial to adjust.

(1) Principle of vibration direction angle indication (see Figure IV)<br>The angle between the vibration direction line of the vibration motor and the vibration bench line α is called the vibration direction angle, and the scale of 20 to 60 on the indicator plate indicates the vibration direction angle value. When working, the center of the four small circles on the indicator disk re-consums a straight line (i.e., a vibration direction line) along the vibrational direction with the dotted line formed by the vibration. See Figure V.a), at this time, by indicating that the disk center "O" perpendicular to the vibrational table line of the vibration direction tick line of the scale plate to the tick value, that is, the vibration direction angle value, if the vibration direction angle is greater than the angle indicated by the indicator disk, the small circle and the dotted line to do cross motion (as shown in Figure 5 b, c), at this time should be released at the center of the dial screws to make adjustments.

① Principle of vibration direction angle indication (see Fig. 4)<br>The angle α between the vibration direction line of the vibration motor and the vibration table line is called the vibration direction angle, and the scale of 20-60 on the indicator plate indicates the value of the vibration direction angle. During operation, the centers of the four small circles on the indicator plate coincide with the dotted line formed during vibration along the vibration direction to form a straight line (i.e. vibration direction line, see Fig. 5. A), The scale value that the straight line perpendicular to the vibration table top line and the vibration direction angle scale line on the dial circle center "O" coincide with the vibration direction angle scale line on the dial plate is the vibration direction angle value. If the vibration direction angle is greater than the angle indicated by the indicator plate, the small circle and the dotted line will move up and cross (as shown in B and C in Fig. 5). At this time, the screw at the center of the dial should be loosened for adjustment.<br>
