Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please see Figure 1-5 A detection device for bottled food packaging includes a detection conveyor body 1. A first food packaging bottle conveyor belt 2 and a second food packaging bottle conveyor belt 3 are provided at one end of the inner surface of the detection conveyor body 1, and a third food packaging bottle conveyor belt 4 is provided at the other end of the inner surface of the detection conveyor body 1. A material guide notch 5 is provided on the surface of the detection conveyor body 1. A first support seat 7 is fixedly connected to the outer surface of the detection conveyor body 1. An air pump 8 (the core function of the air pump is to achieve gas pressure change through mechanical energy conversion; its working principle includes compressing or drawing air to form a pressure difference; for example, an electric air pump compresses air by electric power, while a manual or foot-operated air pump relies on human operation, as per existing technology) is fixedly connected to the outer surface of the air pump 8's air guide pipe 9. A jet pipe 10 is fixedly connected to the outer surface of the detection conveyor body 1. A second support seat 11 is fixedly connected to the outer surface of the second support seat 1. A photoelectric sensor 12 is fixedly connected to the inner surface (the photoelectric sensor is based on the photoelectric effect and uses photoelectric devices (such as light-emitting diodes, photodiodes, etc.) to convert light signals into electrical signals. Its core components usually include three parts: a light-emitting part (emitter), a light-receiving part (receiver), and a detection circuit. When light is blocked or reflected by an object, the change in the amount of light in the light-receiving part is converted into an electrical signal output, thereby realizing the detection function; this is existing technology). A cylinder 13 is fixedly connected to the outer surface of the second support base 11 (easy to use and control; this is existing technology; easy to use). A push plate 14 is fixedly connected to the end face of the push rod of the cylinder 13. The packaging bottles are transported by the first food packaging bottle conveyor belt and the second food packaging bottle conveyor belt, and the packaging bottles are transported and removed by the third food packaging bottle conveyor belt. During detection, air is blown by an air pump and photoelectric detection is used to detect both empty plastic bottles and empty glass bottles, which is convenient for flexible detection and removal of empty bottles.
[0025] An inclined positioning guide plate 6 is provided on the inner surface of the main body 1 of the inspection conveyor; when the packaging bottle is conveyed on the first food packaging bottle conveyor belt 2 and the second food packaging bottle conveyor belt 3, it can be guided by the inclined positioning guide plate 6, which can drive the packaging bottle to follow the inclined positioning guide plate 6 for easy inspection.
[0026] Two sets of jet pipes 10 are fixedly distributed on the outer surface of the air guide pipe 9, and the jet pipes 10 are fixedly connected to the inner surface of the first support 7; the two sets of distributed jet pipes 10 can guide air out to easily blow away the empty plastic bottle.
[0027] The push plate 14 is located on the lower end surface of the second support base 11, and the length of the push plate 14 is greater than the width of the second support base 11; it facilitates pushing the empty bottles that pass by and is easy to use.
[0028] The first food packaging bottle conveyor belt 2 and the second food packaging bottle conveyor belt 3 are set horizontally and are close to each other to facilitate the conveying of packaging bottles; the third food packaging bottle conveyor belt 4 is set at a lower height than the first food packaging bottle conveyor belt 2 and the second food packaging bottle conveyor belt 3; the first food packaging bottle conveyor belt 2 and the second food packaging bottle conveyor belt 3 are used to convey packaging bottles, and the third food packaging bottle conveyor belt 4 can convey pushed-down empty bottles and can transport empty bottles away.
[0029] The first food packaging bottle conveyor belt 2, the second food packaging bottle conveyor belt 3, and the third food packaging bottle conveyor belt 4 are made of rubber food packaging bottle conveyor belt material; they have high friction and facilitate the conveying of packaging bottles.
[0030] In use, a first food packaging bottle conveyor belt 2 and a second food packaging bottle conveyor belt 3 are installed on one end of the inner surface of the detection conveyor body 1. The rotational speed of the first food packaging bottle conveyor belt 2 is less than that of the second food packaging bottle conveyor belt 3, which rotates faster. When the first food packaging bottle conveyor belt 2 transports the bottles to the second food packaging bottle conveyor belt 3, they can be quickly transported, which can increase the distance between the bottles. An inclined positioning guide plate 6 is provided on the inner surface of the detection conveyor body 1. The bottles are transported on the first food packaging bottle conveyor belt 2... When conveying on the second food packaging bottle conveyor belt 3, the bottle can be guided by the inclined positioning guide plate 6, which can guide the bottle along the inclined positioning guide plate 6 for easy inspection; and the outer end surface of the detection conveyor body 1 is fixedly connected to the first support 7, the outer surface of the first support 7 is fixedly connected to the air pump 8, and the outer surface of the air pump 8's air pipe 9 is fixedly connected to the air jet pipe 10. When the air jet is blown, it can blow towards the passing plastic packaging bottles. If the bottle is empty, it will be blown away directly, so that the empty bottle can fall on the surface of the third food packaging bottle conveyor belt 4, which is convenient for detecting empty plastic packaging bottles and is convenient and flexible to use.
[0031] If the packaging bottle is a glass bottle, the bottle itself is heavy and cannot be blown away by an air pump. In this case, a second support seat 11 is fixedly connected to the outer surface of the main body 1 of the detection conveyor seat. A photoelectric sensor 12 is fixedly connected to the inner surface of the second support seat 11. A cylinder 13 is fixedly connected to the outer surface of the second support seat 11. A push plate 14 is fixedly connected to the end face of the push rod of the cylinder 13. The photoelectric sensor 12 can detect whether there is food inside the passing glass bottle. If there is no food, the control system sends a command, which can drive the push plate 14 through the cylinder 13 to push and squeeze, which can push the empty glass bottle to move and make the empty bottle fall on the surface of the third food packaging bottle conveyor belt 4. This is convenient for detecting empty plastic packaging bottles and is easy and flexible to use.
