[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown in the figure, the packaging bag detection and sorting mechanism provided by this utility model includes a slide 1, a circular opening 4 on the inner wall of the slide 1, a turntable 5 inside the circular opening 4, a baffle 6 fixed on one side of the outer wall of the turntable 5, a housing 10 fixed on one side of the outer wall of the slide 1, a rotating shaft 11 fixed at the center of the turntable 5, the rotating shaft 11 and the housing 10 being connected by a bearing, one end of the rotating shaft 11 extending into the interior of the housing 10 and a driven gear 12 fixed thereon, a motor 14 fixed on one side of the outer wall of the housing 10, the output shaft of the motor 14 extending into the interior of the housing 10 and a driving gear 13 fixed thereon, the driving gear 13 meshing with the driven gear 12.

[0024] Specifically, in this embodiment, a slide 1 is included. In use, the slide 1 is fixed at an angle at the outlet of the existing packaging bag detection equipment. The packaging bag detection equipment has a vision camera inside. The detection principle of the specific detection equipment for packaging bags is as follows: when the packaging bag to be detected reaches the detection position, a detection signal is triggered, the vision camera immediately takes a picture, and completes the picture taking according to the preset exposure time. The vision camera immediately calculates the grayscale value at the preset position and compares the calculated grayscale value with the grayscale value of the preset qualified packaging bag. If the grayscale value of the selected area is not within the preset range, it is determined to be unqualified, and this packaging bag will be rejected at the sorting mechanism. The inner wall of the slide 1 has a circular opening 4, which is circular. A turntable 5 is set inside the circular opening 4. A baffle 6 is fixed to one side of the outer wall of the turntable 5. When the defective packaging bag slides down the slide 1, the baffle 6 guides the packaging bag and removes the defective packaging bag. A shell 10 is fixed to one side of the outer wall of the slide 1. A rotating shaft 11 is fixed at the center of the turntable 5. The rotating shaft 11 and the shell 10 are connected to the shell. 10 is connected by bearings, so that the turntable 5 can rotate around the rotating shaft 11, which in turn causes the turntable 5 to drive the baffle 6 to rotate. One end of the rotating shaft 11 extends into the interior of the housing 10 and is fixed with a driven gear 12. A motor 14 is fixed on one side of the outer wall of the housing 10. The output shaft of the motor 14 extends into the interior of the housing 10 and is fixed with a driving gear 13. The driving gear 13 meshes with the driven gear 12. The motor 14 drives the larger diameter driving gear 13 to rotate. The larger diameter driving gear 13 can drive the smaller diameter driven gear 12 to rotate quickly, which makes the turntable 5 and the baffle 6 more sensitive when rotating.

[0025] The present invention provides a packaging bag detection and sorting mechanism, which fixes the baffle 6 to the turntable 5, making the turntable 5 drive the baffle 6 to rotate more stably, and the force at the connection between the baffle 6 and the turntable 5 is uniform, so that the baffle 6 is not easy to break when rotating.

[0026] In another embodiment of this utility model, an oil inlet pipe 15 is fixed to one side of the outer wall of the housing 10. The oil inlet pipe 15 allows lubricating oil to be added to the interior of the housing 10, reducing wear during the meshing transmission of the driving gear 13 and the driven gear 12. One end of the oil inlet pipe 15 is connected to a protective cover 16, which seals the oil inlet pipe 15. A limiting groove 8 is formed on one side of the outer wall of the turntable 5, and a limiting post 9 is fixed to one side of the outer wall of the housing 10. The limiting post 9 extends into the limiting groove 8, and is not higher than the upper surface of the turntable 5 to prevent it from obstructing the packaging bag. The limiting post 9 and the limiting groove 8 ensure that the turntable 5 can only rotate within a fixed range. A defective product outlet 2 and a good product outlet 3 are provided at the bottom of the slide rail 1. Defective packaging bags flow out from defective outlet 2; good packaging bags flow out from good packaging outlet 3. Defective outlet 2 and good packaging outlet 3 are located on both sides of baffle 6. An inclined plate 7 adapted to baffle 6 is fixed on one inner wall of slide 1, and the inclined plate 7 also guides the packaging bags. Through the cooperation of the set limiting groove 8 and limiting post 9, baffle 6 can be accurately rotated to the position corresponding to inclined plate 7, thereby making the packaging bags more reliable during sorting. A convex ring 17 is fixed on the outer wall of turntable 5, and a guide wheel 18 is rotatably connected to one outer wall of slide 1. The outer wall of guide wheel 18 is provided with an arc groove 19, which is adapted to the convex ring 17. The cooperation between the arc groove 19 of guide wheel 18 and convex ring 17 makes turntable 5 more stable when rotating.

[0027] Working principle: In use, when the defective packaging bag is about to slide down the slide 1, the motor 14 drives the drive gear 13 to rotate. The drive gear 13 drives the driven gear 12 and the rotating shaft 11 to rotate, causing the rotating shaft 11 to drive the turntable 5 and the baffle 6 to rotate. Under the action of the limiting groove 8 and the limiting post 9, one end of the baffle 6 engages with the inclined plate 7. At this time, the defective packaging bag will slide out of the defective outlet 2 under the blocking action of the baffle 6. When the good packaging bag is about to slide down the slide 1, the motor 14 drives the drive gear 13 to rotate in the opposite direction. The drive gear 13 drives the driven gear 12 and the rotating shaft 11 to rotate, causing the rotating shaft 11 to drive the turntable 5 and the baffle 6 to rotate. Under the action of the limiting groove 8 and the limiting post 9, the baffle 6 returns to the state corresponding to the good product outlet 3, thus allowing the good packaging bag to slide out of the good product outlet 3.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
