[0037] How to use:

[0038] First, the moving end of the pneumatic slide 234 in the positioning assembly 23 is moved to the left or right. Then, the tube is placed laterally and pressed downwards onto the first inclined surface 2331 of the two first clamping blocks 237 in the two positioning units. The pressing continues to force the ends of the two first clamping blocks 237 to separate from each other until the tube is inserted between the first arc-shaped grooves 2371 on the two first clamping blocks 237. After that, the two first clamping blocks 237 will clamp the tube by means of their own elastic reset function. Similarly, the tubular structure located in the middle of the tube is also pressed into the second clamping block 239 in the limiting unit in the same way. The second arc-shaped groove 2392 is between; then, the moving end of the pneumatic slide 234 is driven to move to the right or left to reset until a positioning unit is located below the pressure block 233. Then, the telescopic end of the first positioning cylinder 232 is driven to extend outward to drive the pressure block 233 to move down until the two first inclined surfaces 2331 on the pressure block 233 respectively attach to the second inclined surfaces 2372 on the two first clamping blocks 237 in the positioning unit below it and press the lower side of the pressure block 233 onto the pipe. At this time, the end of the pipe that needs to be coated with glue is set backward and extends to the front of the glue storage box 225.

[0039] Next, the servo motor 222 in the glue application assembly 22 is activated to rotate its rotating shaft, thereby driving the glue-dipping rod 224 to a vertically positioned position. This allows the conical tip of the glue-dipping rod 224 to be immersed in the glue contained in the glue storage box 225. Then, the rotating shaft of the servo motor 222 is driven to rotate so that the glue-dipping rod 224 is rotated to a horizontally positioned position, with the glue-dipped conical tip positioned behind the glue application end of the fitting and facing the opening of the fitting application end. Then, the telescopic end of the first moving cylinder 223 is driven to extend outward or retract inward to drive the servo motor 222 forward, thereby driving the glue-dipping rod 224 forward until the glue-dipped conical tip is inserted into the opening of the fitting application end, thus adhering the glue to the inner wall of the opening of the fitting application end. Subsequently, the telescopic end of the first moving cylinder 223 is driven to retract inward or extend outward to drive the glue-dipping rod 224 backward until it leaves the opening of the fitting application end, thus completing the glue application of the fitting.

[0040] In addition, in order to prevent the glue-applying end of the pipe from bending during glue application, it is also necessary to drive the extension and retraction ends of the first anti-loosening cylinder 34 and the second anti-loosening cylinder 31 in the first anti-loosening unit 3 to extend outward so as to drive the two first anti-loosening blocks 33 to move closer to each other, thereby clamping the glue-applying end of the pipe with the help of the first V-groove 331 on the two first anti-loosening blocks 33.

[0041] Meanwhile, the clamping position of the second anti-loosening unit 4 can be adjusted according to the length of the pipe fitting. During adjustment, the extension and retraction ends of the second moving cylinder 41 and the third moving cylinder 43 in the second anti-loosening unit 4 are both extended outward or retracted inward to drive the two second anti-loosening blocks 45 in each second anti-loosening block assembly to move forward or backward until the two second anti-loosening blocks 45 reach the designated position. Finally, the extension and retraction ends of the third anti-loosening cylinder 42 and the fourth anti-loosening cylinder 44 are both driven outward to drive the two second anti-loosening blocks 45 to move closer to each other, thereby clamping the glued end of the pipe fitting with the help of the second V-groove 451 on the two second anti-loosening blocks 45.

[0042] This invention can automatically complete the process of dipping the glue stick 224 in glue, and can also automatically insert the end of the glue stick dipped in glue into the opening of one end of the pipe fitting to achieve glue application, thereby simplifying the operation process and achieving the effect of saving time and effort, thus improving work efficiency and reducing labor costs.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
