[0033] Among them, there is also a heat dissipation and dust removal mechanism. The heat dissipation and dust removal mechanism is used for heat dissipation and dust removal of the vision detection head 26. The heat dissipation and dust removal mechanism includes a rectangular box 27 installed at the upper end of the horizontal part of the L-shaped plate 7. The inner cavity of the inner wall of the rectangular box 27 is a columnar cavity. A second piston block 29 that can slide up and down is arranged in the rectangular box 27.

[0035] In the present invention, during use, the staff places the woven bag to be detected on the first belt conveyor 4. The woven bag is conveyed to the right. When it reaches the uppermost support plate 16, it is detected by the vision detection head 26. The length of the woven bag is greater than the distance between the first belt conveyor 4 and the second belt conveyor 5.

[0036] When the woven bag is qualified, the second belt conveyor 5 will move the woven bag to the right and discharge it from the guide plate 6. When the woven bag is unqualified, the drive motor 9 will start. When the motor 9 starts, it will make the rotating rod 14 rotate through the speed reducer 10, thereby making multiple connecting rods 15 and the support plate 16 rotate. When the rotating rod 14 rotates half a circle, it will make the support plate 16 rotate through the connecting rod 15, and press the unqualified woven bag into the rectangular cavity 2.

[0037] In this process, the rotation of the drive motor 9 will also make the rotating shaft 13 of the transmission belt 11 rotate. At this time, the rotating disk 23 rotates, and then through the drive rod 22, it will make the first piston block 19 reciprocate up and down. Cooperating with the one-way valves in the one-way port 20 and the one-way pipe 21, it will draw in external air and then press it into the inner bottom space of the rectangular box 27. At this time, since the normally open solenoid valve is energized and closed, after the gas is injected, it will push the second piston block 29 to move upward and compress the spring 28. When the drive motor 9 is turned off, the gas will be released through the first connecting pipe 30, pass through the inside of the operation box 25, and then be discharged from the exhaust port 32 in the L-shaped hollow strip 31, blowing to the lower end of the vision detection head 26. While dissipating the heat inside the operation box 25, it cleans the vision detection head 26 to ensure the quality of detection.
