The upper end of the fixing base plate 4 is provided with a drive motor 25, and the output end of the drive motor 25 is connected to a spur gear 26. A rack 27 is provided on one side of the spur gear 26. A connecting plate 28 is connected to the side of the rack 27 away from the spur gear 26. A baffle 29 is connected to the lower end of the connecting plate 28. A vision sensor 210 is provided on the side of the connecting plate 28 away from the rack 27.

[0033] In this embodiment, the unloading component 1, the detection component 2, and the feeding component 3 constitute the unloading mechanism of a plastic bottle inspection machine according to this application, realizing the operation of quantitative unloading and quality inspection of plastic bottles followed by conveying.

[0034] In this embodiment, the visual sensor 210 involved uses image processing technology to detect appearance defects of plastic bottles, such as scratches, stains, deformation, etc.

[0035] In this embodiment, the drive motor 11 is started to drive the rotating column 13 to rotate inside the connecting round shell 16, which causes a plastic bottle in the feeding trough 14 to roll inside the connecting round shell 16 and be conveyed to the upper end of the feeding hole 17, and then fall onto the conveyor belt 33 through the feeding hole 17.

[0036] It should be noted that the inclined baffle 18 can prevent a plastic bottle falling from the discharge hole 17 from falling to the other side.

[0037] Specifically, the drive motor 11 is fixedly connected to the upper end of the fixed base plate 4 and has an extension plate. The rotating shaft 12 is rotatably connected to one side of the connecting round shell 16. The rotating column 13 rotates and slides inside the connecting round shell 16. Two sets of feeding troughs 14 are symmetrically arranged at the upper and lower ends of the rotating column 13. The feeding hole 17 is located at the lower end of the connecting round shell 16. A baffle 18 is located on the side of the feeding hole 17 away from the detection component 2. The feeding barrel 15 is fixedly connected to the upper end of the fixed base plate 4 and has an extension plate. The end of the cylinder 21 away from the push block 22 is fixedly connected to the upper end of the fixed base plate 4 and has an extension plate. The push block 22 slides on the fixed plate 23. The upper part of the fixed plate 23 has a feeding hole 24 located at the upper end of the fixed plate 23. The fixed plate 23 and the feeding hole 24 are provided in two sets and are arranged horizontally and symmetrically. The end of the drive motor 25 away from the spur gear 26 is fixedly connected to the extension plate provided at the upper end of the fixed base plate 4. The spur gear 26 is meshed with the rack 27. The detection component 2 also includes a connecting shell 211, which is fixedly connected to the extension plate provided at the upper end of the fixed base plate 4. The connecting plate 28 slides in the connecting shell 211. The vision sensor 210 and the rack 27 slide on both sides of the connecting shell 211. The vision sensor 210 is located on the side of the connecting plate 28 near the push block 22.

[0038] In a preferred embodiment, by starting the second drive motor 25, the spur gear 26 is rotated, which in turn drives the rack 27 to descend. When the second baffle 29 descends to a certain height, it stops and blocks a plastic bottle on the conveyor belt 33.

[0039] In a preferred embodiment, the plastic bottle is inspected by a vision sensor 210. When the inspection fails, the vision sensor 210 transmits a signal to a controller (not shown). The controller then controls the start cylinder 21 to push the pusher block 22 so that a bottle on the conveyor belt 33 slides off the conveyor belt 33 through the feeding hole 24 and is collected by a collection box (not shown).

[0040] Specifically, the feeding component 3 is located below the detection component 2, and the feeding component 3 includes a drive motor 31, and the output end of the drive motor 31 is fixedly connected to a pulley 32. At the same time, a conveyor belt 33 is provided on the outer side of the pulley 32, and a fixing plate 2 34 is fixedly connected to the upper end of the fixing base plate 4. The end of the drive motor 31 away from the pulley 32 is fixedly connected to an extension plate provided on the upper end of the fixing base plate 4, and the pulley 32 is rotatably connected to the fixing plate 2 34. There are two sets of pulleys 32 and they are located on both sides of the conveyor belt 33. At the same time, the fixing plate 1 23 is located on both sides of the conveyor belt 33, and the baffle 18 is located between the two sets of fixing plates 1 23.

[0041] In a preferred embodiment, the drive motor 31 is started to drive the pulley 32 to rotate, which in turn drives the conveyor belt 33 to transport the plastic bottles.

[0042] It should be noted that a plastic bottle, which is blocked by baffle 29, is driven by conveyor belt 33 to rotate on one side of the lower end of baffle 29, allowing for comprehensive testing.

[0043] In use, firstly, place the plastic bottle into the feeding hopper 15. One of the plastic bottles in the feeding hopper 15 falls into the feeding trough 14. Start the drive motor 11 to drive the rotating column 13 to rotate within the connecting shell 16, causing one plastic bottle in the feeding trough 14 to roll within the connecting shell 16 and be conveyed to the upper end of the feeding hole 17. It then falls through the feeding hole 17 onto the conveyor belt 33. Start the drive motor 31 to drive the pulley 32 to rotate, which in turn drives the conveyor belt 33 to transport the plastic bottle. Start the drive motor 25 to drive the spur gear 26 to rotate, which in turn drives the rack 27 to descend. When the baffle 29 descends to a certain height, it stops, and the baffle 29 then guides the conveyor belt. A plastic bottle is blocked on conveyor belt 33. The visual sensor 210 performs quality inspection on the plastic bottle. The plastic bottle blocked by the baffle 29 is rotated on one side of the lower end of the baffle 29 via conveyor belt 33 for comprehensive inspection. When the inspection fails, the visual sensor 210 transmits a signal to the controller. The controller controls the start cylinder 21 to push the push block 22 so that a bottle on conveyor belt 33 slides off the conveyor belt 33 through the feeding hole 24 and is collected. After completion, the drive motor 25 is started, which drives the spur gear 26 to rotate and drive the baffle 29 to rise, and the bottle is continued to be transported via conveyor belt 33.

[0044] The feeding mechanism of this plastic bottle inspection machine ensures an accurate and stable quantity of plastic bottles conveyed each time, avoiding waiting time caused by insufficient or excessive quantities, further improving overall production efficiency. It also ensures accurate positioning of the plastic bottles during conveying, providing a stable foundation for subsequent inspection work. Simultaneously, it accurately identifies and removes substandard plastic bottles, thus guaranteeing the quality of products entering the market and ensuring consistent quality across batches, thereby improving product stability and reliability.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
