[0045] In this embodiment of the present invention, preferably, the adjusting device of the dispensing valve 3 is mainly used to adjust the position and dispensing volume of the dispensing valve 3 before dispensing glue to the product, so as to avoid positional deviation of the dispensing valve 3 during dispensing and affecting the dispensing effect. The adjusting device of the dispensing valve 3 mainly includes a first conveying component 1, a fine-tuning component 2, and a dispensing valve 3. The first conveying component 1 is mounted on the frame 11. The first conveying component 1 is provided with a first mounting plate 12 connected to the fine-tuning component 2. The fine-tuning component 2 is mounted on the first mounting plate 12, and the dispensing valve 3 is mounted on the fine-tuning component 2.

Mounting plate 12, fine-tuning component 2 connected to the first mounting plate 12, and dispensing valve 3 set on fine-tuning component 2 can be moved along the X-axis and Z-axis directions, thereby greatly adjusting the position of dispensing valve 3. At the same time, by using fine-tuning component 2 to adjust the position of dispensing valve 3 in the X-axis, Y-axis, and Z-axis directions, the position of dispensing valve 3 can be adjusted more precisely. Meanwhile, the adjusting component 31 on dispensing valve 3 can adjust the dispensing amount of dispensing valve 3 so that the dispensing position of dispensing valve 3 is aligned with the dispensing position of the product. Adjusting the dispensing amount of dispensing valve 3 can prevent excessive dispensing amount from causing deviation in dispensing position and affecting the dispensing effect of the product.

[0046] In one embodiment of this utility model, a first conveying assembly 1 is mounted on a frame 11 and connected to a fine-tuning assembly 2 via a first mounting plate 12 on the first conveying assembly 1. A dispensing valve 3 is mounted on the fine-tuning assembly 2, so that the first conveying assembly 1 drives the first mounting plate 12, the fine-tuning assembly 2, and the dispensing valve 3 to move along the X-axis and Z-axis directions to adjust the dispensing position of the dispensing valve 3. The fine-tuning assembly 2 is used to fine-tune the position of the dispensing valve 3 in the X-axis, Y-axis, and Z-axis directions to ensure that the position of the dispensing valve 3 is adjusted to a large extent before fine-tuning to avoid deviation in the dispensing position. An adjustment assembly 31 is provided on the dispensing valve 3, which can be used to adjust the dispensing volume of the dispensing valve 3, which can also avoid deviation in the dispensing position and affect the dispensing effect.

The first push block 321 is moved by air pressure, and the first push block 321 pushes the ejector pin 34 to move. The end of the ejector pin 34 will be stuck after it moves. At the feed inlet 35, the movement of the ejector pin 34 can open or close the feed inlet 35, realizing the conveying or stopping of the adhesive material. The first push rod 311 in the adjusting component 31 can adjust the distance that the first push block 321 pushes the ejector pin 34 to move, thereby adjusting the position of the ejector pin 34 at the feed inlet 35. This controls the amount of adhesive material entering the flow channel from the feed inlet 35, thereby adjusting the amount of adhesive dispensing from the dispensing needle 33. The adjustment of the first knob of the adjusting component 31 can be similar to the principle of an inside micrometer, finely adjusting the amount of adhesive dispensing.
