Description

Technical Field

[0001] This utility model relates to the field of PET bottle inspection technology, specifically to an automatic metal foreign object identification device for PET bottle production lines. Background Technology

[0002] PET bottles are a widely used type of plastic packaging container, mainly made of polyethylene terephthalate (PET). They have advantages such as light weight, heat resistance, pressure resistance, and environmental friendliness, making them one of the mainstream choices in the modern packaging industry.

[0003] In the production process of PET bottles, as equipment speeds increase, if a metal foreign object (such as a metal nut, wire, or other metal object) falls into an empty bottle at some stage of production, and the production line lacks metal detection and rejection equipment, it cannot be identified and removed. This results in the metal foreign object being mixed into the product and circulating in the market, causing quality problems, affecting consumer safety, and impacting the company's image. Currently, existing technology generally uses manual visual inspection to manually remove PET bottles containing metal foreign objects. However, this method is inefficient and prone to human error, leading to a high defect rate and low production efficiency. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an automatic metal foreign object identification device for PET bottle production lines. By setting up a mutually cooperating support and fixing frame and a metal foreign object detection mechanism in the automatic metal foreign object identification device for PET bottle production lines, it is possible to automatically, quickly, continuously and accurately identify and remove PET bottles containing metal foreign objects during high-speed movement, thereby improving production efficiency, reducing production costs, and solving the problems of low efficiency and low accuracy of manual inspection and removal in the existing industry.

[0005] This utility model provides an automatic metal foreign object identification device for a PET bottle production line. The device is installed inside a PET bottle production equipment, which includes a PLC controller and a PET bottle transport robot arm. The device comprises a support frame and a metal foreign object detection mechanism. The metal foreign object detection mechanism is fixedly connected to the PET bottle production equipment via the support frame. The mechanism is located directly below the PET bottle transport robot arm and cooperates with the PET bottles being transported by the robot arm. The mechanism is connected to the PLC controller for feedback, and the PLC controller is connected to the PET bottle transport robot arm for control. The PLC controller can receive information about PET bottles containing metal foreign objects from the detection mechanism and control the robot arm to accurately reject PET bottles containing metal foreign objects after a delay.

[0006] The present invention is further improved by wherein the metal foreign object detection mechanism is a pulse induction metal detector, which can identify metal foreign objects inside PET bottles.

[0007] In a further improvement to this invention, the metal foreign object detection mechanism is bolted to the support frame.

[0008] In a further improvement of this utility model, the support and fixing frame is bolted to the PET bottle production equipment.

[0009] In a further improvement to this invention, the support and fixing frame is a metal support rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an automatic metal foreign object identification device for PET bottle production lines. By setting up a mutually cooperating support frame and metal foreign object detection mechanism in the automatic metal foreign object identification device for PET bottle production lines, the PLC controller can receive the PET bottle information with metal foreign objects fed back by the metal foreign object detection mechanism and control the PET bottle transport robot arm to accurately remove the PET bottles with metal foreign objects after a delay. It can realize the automatic, fast, continuous and accurate identification and removal of PET bottles with metal foreign objects during high-speed movement, improve production efficiency, reduce production costs, and solve the problems of low efficiency and low accuracy of manual detection and removal in the existing industry.
