[0024] like Figure 1 and Figure 2As shown, a second pulley 6 is installed on the top of the rotating bearing 4, and a transmission belt 7 is connected between the outer surfaces of the first pulley 5 and the second pulley 6. Through the rotation of the first pulley 5 and the auxiliary action of the transmission belt 7, the second pulley 6 can be synchronously driven to rotate.

The rotation speed of the rotating bearing 4 can be adjusted by the speed regulating valve 8 to ensure the stability of the rotation of the rotating bracket 11.
[0026] like Figure 1 and Figure 3 As shown, the first sensor 13 and the second sensor 18 are matched with the rotating bracket 11, and the third sensor 19 is provided on the inner surface of the rotating bracket 11. Through the cooperation of the first sensor 13 and the second sensor 18, the position of the rotating bracket 11 can be detected.
[0027] like Figure 1 and Figure 3 As shown, the third sensor 19 is matched with the dispensing valve bracket 2, and the front surface of the main bracket 10 is fixedly connected to the glue barrel bracket 3.

[0029] The usage and working principle of this device are as follows: fix the dispensing valve on the dispensing valve bracket 2, and fix the glue container on the glue barrel bracket 3. When the dispensing valve needs to be rotated, the rotating cylinder 9 is started to drive the first pulley 5 to rotate.

At the same time, with the cooperation of the first spring 12 and the second spring 15, it can be used to provide tension and compensate for the gap in the movement. The miniaturization and lightweight of the device enable the device to be installed on the dispensing machine and can move with the dispensing head in the X, Y, and Z directions to achieve high-precision rotation and tilting of the dispensing valve, improve dispensing accuracy, improve the degree of automation, and speed up production efficiency.
