[0003] During the capping process after filling, the bottle caps on the top of some packaging boxes may lift up when they are screwed on, which affects the sealing after filling. It is necessary to conduct defect inspection on them and remove the packaging that does not meet the standards. Utility Model Content

[0004] The purpose of the utility model is to provide a filling machine with a packaging box packaging defect detection function to solve the problems raised in the above background technology.

[0005] The technical solution of the utility model is: a filling machine with a packaging defect detection function for a packaging box, comprising a feeding frame, a filling and capping mechanism is installed on the feeding frame, a feeding belt is installed in the feeding frame, a symmetrical notch is provided on the feeding frame, a detection mechanism for detecting packaging defects is installed between two of the notches, the detection mechanism comprises a lifting plate slidably installed in the notch, a guide column slidably inserted on the lifting plate is fixed in the notch, a stud threadedly inserted on the lifting plate is rotatably installed on the inner wall of the bottom of the notch, adjacent side walls of the two lifting plates are provided with notches, infrared transmitters and infrared receivers equidistantly distributed are respectively installed in the two notches, a first material guiding mechanism is installed on a side of the feeding frame close to the feeding end, a second material guiding mechanism is installed on a side of the feeding frame close to the discharging end, a lower material frame installed on the side wall of the feeding frame is provided at the discharging end of the second material guiding mechanism, and a rejecting mechanism located below the notch is installed on a side of the feeding frame away from the first material guiding mechanism.

When the bottle cap is tilted when packaged, the infrared receiver cannot fully receive the optical signal of the infrared transmitter, and it is determined that the bottle body has a packaging defect, and the rejection mechanism is used to push it to the conveyor belt close to the side of the unloading rack. On the contrary, when the infrared receiver fully receives the optical signal of the infrared transmitter, it means that the top of the bottle body is in a flat packaging state, and the rejection mechanism does not push the material, and the conveyor belt continues to drive the bottles with complete packaging and packaging defects to continue to move, and the second guide mechanism guides the rejected defective bottles into the unloading rack for discharge, thereby achieving the purpose of bottle separation and facilitating use.

[0007] Preferably, the first material guiding mechanism and the second material guiding mechanism both have a rotating shaft, a material guiding plate fixed on the rotating shaft, and a damping and tightening member abutting against an outer wall of the rotating shaft.

[0012] The effect achieved by the above components is: the push plate is driven to extend by the electric telescopic rod, and the unqualified bottles are pushed toward the lower rack to achieve the purpose of rejection.

[0013] Preferably, a cover plate is fixed to the top of the conveying rack, and the cover plate is located above the detection mechanism.

[0014] The effect achieved by the above components is: the cover plate can be used to provide light shielding protection for the top of the detection mechanism, thereby improving the detection accuracy.

[0015] The utility model provides a filling machine with a packaging box packaging defect detection function through improvement, which has the following improvements and advantages compared with the prior art:

[0016] The device uses linearly distributed infrared transmitters to output optical signals to the top of the bottle body.

The conveyor belt 2 moves, and the linearly distributed infrared transmitters 53 are used to output optical signals to the top of the bottle body. When the bottle cap is tilted, the infrared receiver cannot completely receive the optical signal of the infrared transmitter 53, and it is determined that the bottle body has a packaging defect. The rejection mechanism 6 is used to push it to the conveyor belt 2 close to the side of the unloading rack 8. On the contrary, when the infrared receiver completely receives the optical signal of the infrared transmitter 53, it means that the top of the bottle body is in a flat packaging state. The rejection mechanism 6 does not push the material, and the conveyor belt 2 continues to drive the fully packaged and defectively packaged bottles to continue to move. The second guide mechanism 7 removes the defective bottles. The bottle bodies are introduced into the discharge rack 8 for discharge, so as to achieve the purpose of separating the bottle bodies. The first material guiding mechanism 3 and the second material guiding mechanism 7 both have a rotating shaft 31, a guiding plate 32 fixed on the rotating shaft 31 and a damping and tightening member 33 that is in contact with the outer wall of the rotating shaft 31.

The cover plate 4 can be used to perform light shielding protection on the top of the detection mechanism 5 to improve the detection accuracy.

[0028] The utility model provides a filling machine with a packaging defect detection function for packaging boxes. The working principle of the filling machine is as follows: the bottle body after filling and sealing by the filling and capping mechanism can be conveyed through the conveyor belt 2 in the conveyor rack 1. The bottle body is guided by the first guide mechanism 3 to move along the conveyor belt 2 on the side of the rejection mechanism 6. The linearly distributed infrared transmitter 53 is used to output an optical signal to the top of the bottle body. When the bottle cap is tilted, the infrared receiver cannot fully receive the optical signal of the infrared transmitter 53, and it is determined that the bottle body has a packaging defect. The rejection mechanism 6 is used to push it to the conveyor belt 2 close to the side of the unloading rack 8. On the contrary, when the infrared receiver fully receives the optical signal of the infrared transmitter 53, it means that the top of the bottle body is in a flat packaging state. The rejection mechanism 6 does not push the material, and the conveyor belt 2 continues to drive the fully packaged and defectively packaged bottles to continue to move. The second guide mechanism 7 guides the rejected defective bottles into the unloading rack 8 for discharge, thereby achieving the purpose of bottle separation.
