Description

Technical Field

[0001] The utility model relates to the technical field of deoxidizer detection, and more specifically to a deoxidizer detection tool for plastic-packaged food. Background Art

[0002] In the food industry, the primary function of an oxygen absorber is to remove oxygen from packaging, thereby slowing the oxidation process and extending the shelf life of the food. Through a chemical reaction, the oxygen absorber absorbs oxygen from the packaging, reducing its impact on the food. The oxygen absorber is packaged individually in a plastic bag and then encapsulated with the food.

[0003] After plastic-packaged food is sealed, it needs to be tested for the presence of deoxidizers. Only qualified products can be packaged and shipped. In large-scale production, this testing is typically performed using visual cameras or ultrasonic technology. Visual camera testing requires independent inspection stations and a clamping device to hold the product. This complex structure and large footprint make subsequent maintenance difficult.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and convenience of description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Numerous modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0021] like Figure 1-3As shown, the technical solution of the present invention provides a deoxidizer detection tool for plastic-packaged food, comprising a conveyor line 1, a detection device 3, a conveyor line 2 2, and a rejection device located on the conveyor line 2 2. The conveyor line 1 is higher than the conveyor line 2 2. The detection device 3 includes a transition plate 31 connecting the conveyor lines 1 and 2, and visual inspection modules located above and below the transition plate 31. The transition plate 31 is a transparent plate. The visual inspection modules inspect the product as it slides from the transition plate 31 to the conveyor line 2 2.

[0022] In the above scheme, short-shelf-life products, such as bread, are inspected for the presence of deoxidizer after packaging. If not, they are removed from the production line. The packaged products are placed on conveyor line 1 and fall from the end of conveyor line 1 onto the detection transition plate 31. Due to inertia, the products slide at a certain speed onto conveyor line 2 2. During the sliding process, the visual inspection module detects whether the packaging bag contains deoxidizer. Both conveyor lines 1 and 2 use belt conveyors to ensure stable product conveying posture. To ensure that the products slide at a certain speed, the speed of conveyor line 1 is set at 80m / min in this embodiment.

[0023] The transition plate 31 is removable and has an angle of 30-35° with the horizontal plane. It is constructed of a smooth, transparent surface, such as acrylic, to enhance the accuracy of the visual inspection module. The 30-35° angle ensures smooth product sliding while allowing the visual inspection module to accurately inspect the product.

[0024] The visual inspection module is housed within the cabinet 5 and includes light source assembly 1 and light source assembly 2, located above and below the transition plate 31, and a detection camera 34 located to one side of light source assembly 2. The deoxidizer is located at the bottom of the product, and both light source assembly 1 and light source assembly 2 illuminate the inspection process to better visualize the deoxidizer's outline, allowing the detection camera 34 to capture a clearer image.

[0025] Light source assembly 1 includes two symmetrically arranged planar light sources 32, tilted and facing each other at an adjustable angle. This tilted and adjustable angle reduces the reflectivity of transition plate 31 and thus reduces interference with detection camera 34. Light source assembly 2 includes a horizontally arranged planar light source 33, which provides fill light to the bottom of transition plate 31.

[0026] The detection camera 34 is a CCD camera. The detection camera 34 is located on the side of the transition plate 31 close to the conveyor line 2 2. It is set close to the conveyor line 2 2 because the posture of the product is more stable after sliding a distance and the detection is more accurate.

[0027] The rejecting device includes a pneumatic blowing nozzle 4 located above the conveyor line 2. After the product is inspected, it is conveyed through the conveyor line 2. When unqualified products pass through the pneumatic blowing nozzle 4, they are blown out of the conveyor line, thereby rejecting unqualified products.

[0028] This solution can detect the presence of deoxidizers in short-shelf-life plastic-packaged foods, ensuring food safety. The detection device 3 is set between two conveyor lines, using a transparent transition plate 31 as the intermediate transition section. It takes up little space and is easy to install and disassemble, with an ingenious design.

[0029] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
