[0006] Optionally, the conveyor belt includes a first belt body, a corner belt body, and a second belt body, all rotatably mounted on the frame and connected end to end in sequence. The first belt body, the corner belt body, and the second belt body can sequentially support and transport the glass bottle, and the included angle between the first belt body and the second belt body is less than or equal to 90 degrees.
[0007] Optionally, the ejector port is located at the corner belt and on the side of the corner belt with a longer arc length.
[0008] Optionally, the conveyor belt rotates intermittently. When a glass bottle moves to the inspection station, the conveyor belt stops. After the metal detector completes the inspection, the conveyor belt rotates. The deflector is configured to extend downward when the metal detector detects a defective glass bottle. The defective glass bottle can be stopped by the deflector and tilted backward and placed horizontally on the conveyor belt. The length of the rejection port is greater than the height of the glass bottle.
[0009] Optionally, the rejection mechanism includes a cylinder and a push rod. The cylinder body is fixed on the frame, and the push rod is connected to the piston rod of the cylinder.

[0010] Optionally, baffles are provided on both sides of the dial, and the two baffles are located on both sides of the bottle opening of the glass bottle and behind the dial.
[0011] Optionally, the conveyor belt is arranged to gradually slope downwards along its width direction from the side away from the discharge port to the side closer to the discharge port.
[0012] Optionally, it also includes a rejection conveyor belt, which is disposed on the frame and connected to the conveyor belt at the rejection port, and the defective glass bottles ejected by the rejection mechanism fall onto the rejection conveyor belt.
[0013] Compared with the prior art, the above-mentioned technical solutions of the beverage glass bottle metal foreign object detection device provided by the present invention have at least one of the following technical effects:
[0014] During the inspection process, several glass bottles are arranged on a conveyor belt. The conveyor belt drives the bottles sequentially through the inspection station and the rejection station. When a bottle reaches the inspection station, a metal detector checks for metal impurities. If metal impurities are detected inside the bottle, a deflector extends downwards. As the conveyor belt moves the bottle forward, the deflector blocks the bottle's opening, causing the bottle to tip over onto the conveyor belt. When the tipped bottle moves to the rejection port, the rejection mechanism pushes the defective bottle out of the rejection port. Furthermore, for qualified bottles detected by the metal detector, the deflector remains in place and does not extend, allowing the qualified bottles to pass under the deflector upright. The rejection mechanism also does not extend when a qualified bottle passes the rejection station. This glass bottle metal foreign object detection device enables automatic detection of metal foreign objects in glass bottles and automatically rejects defective bottles, saving labor costs and improving inspection efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0034] like Figures 1 to 4As shown, this utility model provides a metal foreign object detection device for beverage glass bottles 700, including a frame 100, a conveyor belt 200, a metal detector 300, a deflector 500, a rejection mechanism 400, two first guide rods 800 and two second guide rods 900.
[0035] The frame 100 includes an inspection station 110 and a rejection station 120. A conveyor belt 200 is mounted on the frame 100 to support and transport glass bottles 700 forward. Several glass bottles 700 are arranged on the conveyor belt 200, with the spacing between adjacent glass bottles 700 greater than the height of the glass bottles 700. A metal detector 300 is located at the inspection station 110 of the frame 100 to detect whether the glass bottles 700 contain metal impurities. A deflector 500 is vertically mounted at the inspection station 110 of the frame 100 and located above the conveyor belt 200. The deflector 500 is configured to extend and retract vertically. When the deflector 500 extends downward, its lower part is located at the bottle neck 710 of the glass bottle 700. At the front of the position, two first guide rods 800 are both set on the frame 100 and located on both sides of the conveyor belt 200 in the conveying direction. Two second guide rods 900 are both set on the frame 100 and located between the first guide rods 800 and the conveyor belt 200. One of the second guide rods 900 is broken at the rejection station 120 to form a rejection port 130. The distance between the second guide rod 900 and the conveyor belt 200 is less than the minimum outer diameter of the glass bottle 700. The distance between the first guide rod 800 and the conveyor belt 200 is greater than the maximum outer diameter of the glass bottle 700 and less than the height of the glass bottle 700. The rejection mechanism 400 is set on the frame 100 and is used to push the unqualified glass bottle 700 out of the rejection port 130.
[0036] Understandably, during the inspection process, several glass bottles 700 are arranged on the conveyor belt 200. The conveyor belt 200 can drive the glass bottles 700 to pass through the inspection station 110 and the rejection station 120 in sequence. When the glass bottle 700 moves to the inspection station 110, the metal detector 300 can detect metal impurities in the glass bottle 700. If metal impurities are detected in the glass bottle 700, the deflector 500 extends downward. As the conveyor belt 200 moves the glass bottle 700 forward, the deflector 500 will block the bottle mouth 710 of the glass bottle 700, causing the glass bottle 700 to tip over onto the conveyor belt 200. When the tipped glass bottle 700 moves with the conveyor belt 200 to the rejection port 130, the rejection mechanism 400 pushes the unqualified glass bottle 700 out of the rejection port 130. Furthermore, for qualified glass bottles 700 detected by the metal detector 300, the deflector 500 will remain in place and will not extend. Therefore, qualified glass bottles 700 can pass under the deflector 500 while remaining upright. When qualified glass bottles 700 pass through the rejection station 120, the rejection mechanism 400 will not extend. The glass bottle 700 metal foreign object detection device of this invention can automatically detect metal foreign objects in glass bottles 700, and can automatically reject unqualified glass bottles 700, saving labor costs and improving detection efficiency. The metal detector 300 is a commonly used device in the field for detecting metal residues in glass bottles 700; therefore, its detection principle is a conventional technical method in this field and will not be elaborated further here.
[0037] It should be noted that this utility model can be used in conjunction with a sensor to detect the position and quantity of glass bottles 700. The sensor can be a distance sensor or a counting sensor. For example, after the sensor at the detection station 110 detects that the Nth glass bottle 700 is a defective glass bottle 700, the sensor at the deflector 500 pushes down the corresponding Nth glass bottle 700. At the same time, the rejection mechanism 400 pushes the corresponding Nth glass bottle 700 out of the rejection port 130.
[0038] like Figure 1 and Figure 3As shown, in some embodiments of this utility model, the conveyor belt 200 includes a first belt body 210, a corner belt body 220, and a second belt body 230, all rotatably mounted on the frame 100 and sequentially connected end-to-end. The first belt body 210, the corner belt body 220, and the second belt body 230 can sequentially support and transport glass bottles 700. The included angle between the first belt body 210 and the second belt body 230 is less than or equal to 90 degrees. Since the distance between the first guide rod 800 and the conveyor belt 200 is greater than the maximum outer diameter of the glass bottle 700 and less than the height of the glass bottle 700, defective glass bottles 700 can be directly discharged from the rejection port 130 located on the corner belt body 220 under the action of inertia as they move forward with the first belt body 210. In addition, for glass bottles 700 that are not cylindrical in shape, defective materials can be pushed out from the rejection port 130 by means of the pushing action of the rejection mechanism 400.
[0039] like Figure 1 As shown, in some embodiments of this utility model, the rejection port 130 is located at the corner belt 220 and on the side of the corner belt 220 with a longer arc length, so that the unqualified glass bottle 700 can be sent out by inertia through the rejection port 130.
[0040] like Figure 2 As shown, in some embodiments of this invention, the conveyor belt 200 rotates intermittently. When a glass bottle 700 moves to the inspection station 110, the conveyor belt 200 stops. After the metal detector 300 completes its inspection, the conveyor belt 200 rotates again. The intermittent movement of the conveyor belt 200 allows the metal detector 300 sufficient time to inspect the glass bottles 700 passing through the inspection station 110, thus improving inspection accuracy. Furthermore, the lever 500 is configured to extend downwards as shown when the metal detector 300 detects a non-conforming glass bottle 700. Figure 2 As shown by the dotted line indicating the position of the deflector 500, defective glass bottles 700 can be stopped by the deflector 500 and tilt backward, landing horizontally on the conveyor belt 200. Figure 2 The defective glass bottle 700 is initially positioned as shown by the dotted line in the diagram. As the glass bottle 700 continues to move forward, it will tip over onto the conveyor belt 200. The extension and retraction of the lever 500 can be achieved by a cylinder. In addition, the length of the rejection port 130 is greater than the height of the glass bottle 700, so that the defective glass bottle 700 can be smoothly discharged from the rejection port 130 when tipped over.
[0041] Reference Figure 3In some embodiments of this utility model, the rejection mechanism 400 includes a cylinder 410 and a push rod 420. The cylinder body of the cylinder 410 is fixed on the frame 100, and the push rod 420 is connected to the piston rod of the cylinder 410. The push rod 420 is configured to push the glass bottle 700 located at the rejection port 130 towards the rejection port 130 when the piston rod extends. The rejected glass bottle 700 pushed out can fall into the rejection conveyor belt 600 and be subsequently recycled or further cleaned.
[0042] like Figure 4 As shown, in some embodiments of this utility model, baffles 510 are respectively provided on both sides of the lever 500. The two baffles 510 are located on both sides of the bottle mouth 710 of the glass bottle 700 and are positioned behind the lever 500. The lever 500 can stop the bottle mouth 710 during the movement of the glass bottle 700, which can cause the glass bottle 700 to tip over. The two baffles 510 can limit the tipping direction of the glass bottle 700 on both sides of the bottle mouth 710, so that the glass bottle 700 can tilt and fall as far backward as possible.
[0043] In some embodiments of this utility model, the conveyor belt 200 is gradually inclined downward along its own width direction from the side away from the rejection port 130 to the side closer to the rejection port 130 at the rejection port 130. The inclined conveyor belt 200 can improve the smoothness of the glass bottle 700 being sent out of the rejection port 130 and further prevent unqualified glass bottles 700 from getting stuck at the rejection port 130.
[0044] In some embodiments of this utility model, a rejection conveyor belt 600 is also included. The rejection conveyor belt 600 is disposed on the frame 100 and is connected to the conveyor belt 200 at the rejection port 130. The defective glass bottles 700 ejected by the rejection mechanism 400 fall onto the rejection conveyor belt 600. The rejection conveyor belt 600 can transfer the defective glass bottles 700 to a recycling device or a deep cleaning device.
[0045] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
