[0018] 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.

[0019] like Figure 1-3 As shown in the figure, the present invention provides a damaged packaging bag detection and rejection device, including a frame 1. Inside the frame 1, a drive roller 2 and a driven roller 3 are connected by bearings. A conveyor belt 4 is connected between the drive roller 2 and the driven roller 3. A detection mechanism 5 fixed to the frame 1 is provided on the top of the conveyor belt 4. An inclined plate 6 is provided on one side of the conveyor belt 4. The bottom of the inclined plate 6 is hinged to the frame 1, and the top of the inclined plate 6 is adapted to the conveyor belt 4. An electric telescopic rod 7 is hinged inside the frame 1, and the output end of the electric telescopic rod 7 is hinged to the inclined plate 6.

[0020] Specifically, in this embodiment, a frame 1 is included. Inside the frame 1, a drive roller 2 and a driven roller 3 are connected via bearings. The drive roller 2 and the driven roller 3 are installed at the same height. A conveyor belt 4 is connected between the drive roller 2 and the driven roller 3. When the drive roller 2 rotates, it drives the conveyor belt 4 to rotate. The top of the driven roller 3 has a paging mechanism 11 fixed to the frame 1. The paging mechanism 11 can separate stacked packaging bags one by one and at equal intervals onto the conveyor belt 4. The top of the conveyor belt 4 is provided with... An inspection mechanism 5 is fixed to the frame 1. The inspection mechanism 5 is a prior art visual inspection device for packaging bags, which can detect damage on the outer tube of the packaging bag. An inclined plate 6 is provided on one side of the conveyor belt 4. The bottom of the inclined plate 6 is hinged to the frame 1, and the top of the inclined plate 6 is adapted to the conveyor belt 4. The top of the inclined plate 6 is slightly lower than the top of the conveyor belt 4. An electric telescopic rod 7 is hinged inside the frame 1. The output end of the electric telescopic rod 7 is hinged to the inclined plate 6, and the inclined plate 6 is moved by the electric telescopic rod 7.

[0021] This utility model provides a damaged packaging bag detection and rejection device. The electric telescopic rod 7 drives the inclined plate 6 to rotate away from the conveyor belt 4, so that the damaged packaging bags on the conveyor belt 4 can automatically fall to the bottom of the inclined plate 6, thereby achieving the effect of rejecting the damaged packaging bags. This eliminates the need for manual rejection during packaging bag detection, making the rejection of damaged packaging bags more convenient.

[0022] In another embodiment of this utility model, a stop bar 20 fixed to the frame 1 is provided on one side of the active roller 2. The stop bar 20 is adapted to the inclined plate 6 and the stop bar 20 has the effect of blocking the inclined plate 6, so that the inclined plate 6 will not directly contact the conveyor belt 4. A motor 19 is fixed on one side of the outer wall of the frame 1. The output shaft of the motor 19 is connected to the active roller 2 by a key. The motor 19 drives the active roller 2 to rotate. A control host 10 is fixed on one side of the outer wall of the frame 1. The electric telescopic rod 7, the control host 10 and the detection mechanism 5 are electrically connected. The connection principle between the electric telescopic rod 7, the control host 10 and the detection mechanism 5 is the prior art. The control host 10 is also the prior art.

[0023] In another embodiment of this utility model, two vertical plates 8 are fixed inside the frame 1, and a drawer 9 is provided between the two vertical plates 8. The drawer 9 is located at the bottom of the inclined plate 6. The damaged packaging bags are stored in the drawer 9, so that the damaged packaging bags can be easily processed uniformly when the drawer 9 is pulled out.

[0024] In another embodiment of this utility model, connecting plates 15 are fixed on both sides of the detection mechanism 5, and a support plate 12 is fixed inside the frame 1. The bottom of the support plate 12 is connected to an adjusting screw 13 via a bearing, and a handle 14 is fixed to the top of the adjusting screw 13. The adjusting screw 13 can be rotated by the handle 14. The adjusting screw 13 is connected to the connecting plate 15 by a thread. When the adjusting screw 13 rotates, it can drive the detection mechanism 5 to adjust its height. A fixing plate 21 is fixed to the inner wall of the frame 1, and a guide post 17 is fixed between the two fixing plates 21. A sliding bearing is fixed inside the connecting plate 15. 18. The sliding bearing 18 is movably sleeved on the outside of the guide post 17. The sliding bearing 18 is movably sleeved on the outside of the guide post 17, which makes the height adjustment of the detection mechanism 5 more stable. The bottom end of the adjusting screw 13 is connected to the locking nut 16 by thread. The locking nut 16 is located at the bottom of the connecting plate 15. A horizontal plate 22 is fixed inside the frame 1. The horizontal plate 22 is adapted to the conveyor belt 4. The horizontal plate 22 supports the conveyor belt 4, so that the top of the conveyor belt 4 is kept horizontal, and thus the conveyor belt 4 transports the packaging bag more smoothly.

[0025] Working principle: During use, the motor 19 drives the active roller 2 to rotate, which in turn drives the conveyor belt 4 and the driven roller 3 to rotate. The paging mechanism 11 separates the stacked packaging bags onto the conveyor belt 4 in sequence, so that the conveyor belt 4 passes the packaging bags under the detection mechanism 5. When the detection mechanism 5 detects a damaged packaging bag, the detection mechanism 5 transmits an electrical signal to the control host 10. The control host 10 controls the electric telescopic rod 7 to work, so that the electric telescopic rod 7 and the inclined plate 6 rotate away from the conveyor belt 4, thereby causing the damaged packaging bag to fall from the conveyor belt 4 into the drawer 9. Then, the electric telescopic rod 7 drives the inclined plate 6 to re-contact with the stop bar 20, so that the intact packaging bag can slide off the inclined plate 6, thereby achieving the effect of removing the damaged packaging bag.

[0026] 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.
