[0013] In summary, the technical effects and advantages of the utility model are:

[0014] 1. The utility model has a reasonable structure. When the driving motor is started, the horizontal screw is driven to rotate. The rotation of the horizontal screw drives the water spraying head to move horizontally through the horizontal moving block, the fixed plate, the connecting seat, the rotating cylinder, the hollow connecting rod and the telescopic slide rod. In this process, the rotation of the horizontal screw also drives the driving column to rotate circumferentially through the connecting arm and the moving block. The circumferential rotation of the driving column drives the reciprocating swing rod to rotate back and forth, and then drives the water spraying head to swing back and forth through the hexagonal rotating rod, the rotating cylinder, the hollow connecting rod and the telescopic slide rod. Therefore, the water spraying head can swing back and forth while moving horizontally, thereby achieving the purpose of automatically spraying water evenly on the carbon fiber preform. The utility model is simple and convenient to use, reduces the workload and has good practicality.

[0015] 2. In the present invention, when the adjustment knob is turned, the adjustment screw is driven to rotate together through the connecting edge rod. The rotation of the adjustment screw drives the moving block to move up and down in the adjustment slide hole, thereby changing the rotation diameter of the drive column, thereby adjusting the rotation angle of the reciprocating swing arm and the swing amplitude of the water spray nozzle, so that the device can adapt to watering carbon fiber preforms of different sizes, thereby increasing the applicability of the device and improving its practicality.

[0016] 3. In the present invention, when the adjusting knob is pulled downwards until the fixed rod is disengaged from the fixed socket, the adjusting knob will be unlocked. When the adjusting knob is released, the elastic force of the reset spring will squeeze and push the adjusting knob upwards to reset the fixed rod, so that the fixed rod will automatically insert into the fixed socket, and the adjusting knob will be locked. This prevents the adjusting knob from rotating during use, which may cause the swing amplitude of the watering nozzle to change. The nozzle is stable and reliable in use.

[0017] 4. In the utility model, through the coordinated arrangement of the hollow connecting rod, the telescopic slide rod, the adjustment rod, the adjustment socket, the control pull block and the return spring, when the control pull block is pulled or released, the telescopic slide rod can be fixed or released. When the telescopic slide rod is in the released state, the telescopic slide rod can be slid up and down to adjust the height of the water nozzle, thereby achieving the purpose of adaptive watering of carbon fiber preforms of different heights, and having a wider range of applications.

[0027] The swing assembly includes a connecting arm 11 fixedly mounted on the end of the horizontal screw rod 4, an adjusting slide hole is opened on the side of the connecting arm 11, a moving block 12 is slidably installed in the adjusting slide hole, a driving column 13 is fixedly installed on the side of the moving block 12, a reciprocating rocker arm 14 is fixedly mounted on one end of the hexagonal rotating rod 10, a strip slide hole is opened on the side of the reciprocating rocker arm 14, the driving column 13 is adapted to be arranged in the strip slide hole, an adjusting screw 15 is rotatably installed on the top inner wall of the adjusting slide hole, the moving block 12 is threadedly sleeved on the adjusting screw 15, and the bottom end of the adjusting screw 15 extends to the outside of the connecting arm 11 and is installed with a control unit.

[0028] With the above structure, when the drive motor 5 is started, the horizontal screw 4 will be driven to rotate, and the rotation of the horizontal screw 4 will drive the horizontal moving block 6 to move horizontally, and then the watering nozzle 2 can be driven to move horizontally together through the fixed plate 7, the connecting seat 8, the rotating cylinder 9 and the height adjustment component.
