[0002] Plastic cups are disposable containers used for beverages or tea, and are commonly found in beverage shops, cold drink shops, milk tea shops, hotels, restaurants, and coffee shops. During the production process, plastic cups are inspected for shape and weight before packing to remove any that clearly do not meet finished product standards.

[0003] Currently, the method used for this type of inspection often involves transporting plastic cups one by one to an inspection table. After inspection, they are then sent one by one to the next process or for scrap collection. For example, patent publication number CN219899153U provides a defective product recovery device for plastic cup production, comprising two support plates, a conveyor belt disposed between the two support plates, and a power assembly disposed between the two support plates for driving the conveyor belt; a U-shaped frame fixedly mounted on the tops of the two support plates, a detection scanner symmetrically mounted within the U-shaped frame, a motor fixedly mounted on the top of the U-shaped frame, and a motor output shaft extending through the U-shaped frame and fixedly mounted to a plurality of rotating rods; and a plurality of grooves evenly spaced on the conveyor belt, each containing a magnet slidably mounted within the grooves. A measuring scale is fixedly mounted on the top of each magnet, and a load block is fixedly mounted on the top of the measuring scale. The installation of a measuring scale can address the problem of a small number of defective plastic cups remaining in the collection area due to a lack of quality inspection of the plastic cups.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0025] Example 1

[0026] like Figures 1 to 3As shown, this embodiment provides a finished plastic cup screening device, including a screening channel 1 and a discharge channel 2 connected to the tail end of the screening channel 1, the tail end of the screening channel 1 is provided with a pushing mechanism, and the pushing mechanism is arranged in the direction of the discharge channel 2; the pushing mechanism is provided with a control module 33, the middle surface of the screening channel 1 is provided with a graphic imaging module 31, the graphic imaging module 31 is provided with a signal processor 34, and the signal processor 34 is electrically connected to the graphic imaging module 31 and the control module 33 respectively; a weight sensing module 32 is embedded in the tail end surface of the screening channel 1, and the control module 33 is electrically connected to the graphic imaging module 31 and the weight sensing module 32 respectively; in addition, the above-mentioned electrical equipment is also provided with a power supply module 35, and the power supply module 35 is electrically connected to each electrical equipment respectively.

[0027] In this embodiment, the graphic imaging module 31 uses an infrared imager to image the surface of the screening channel 1 through infrared rays, and identifies and collects information such as the outline and quantity of the plastic cups through the obstruction of the plastic cups, and transmits it to the control module 33 after processing by the signal processor 34; the control module 33 is a controller, and the controller can also use a single-chip microcomputer with signal processing function (such as 8051 series single-chip microcomputer, STM32 series single-chip microcomputer), etc.; the power supply module 35 can use a conventional industrial power supply that can provide power for various electrical equipment; the weight sensing module 32 can use an electronic scale to feed back the detected weight information to the controller. By processing the above two signals, it can be concluded whether the plastic cups are qualified, and then the controller adjusts the pushing mechanism to push the qualified plastic cups to the discharge channel 2.

[0028] In this embodiment, the image imaging module 31 first captures and processes images of the plastic cups from a single inspection. This image allows for a preliminary determination of product quality and the number of plastic cups inspected. The weight sensing module 32 then measures the total mass of these plastic cups to determine if they meet the quality standards. If all of these tests pass, the pusher mechanism delivers the finished plastic cups to the discharge channel 2 for subsequent packaging and other processes. Furthermore, any batches of products identified as unqualified through these tests can be retested individually using traditional inspection equipment to prevent qualified products from being mixed with defective products and subsequently recycled or destroyed.

[0029] A detection frame 11 is set up in the middle section of the screening channel 1. The detection frame 11 includes a frame plate 12 arranged parallel to the surface of the screening channel 1. The graphic imaging module 31 is set on a side of the frame plate 12 close to the screening channel 1, and the probe of the graphic imaging module 31 is set facing the surface of the screening channel 1.

[0030] In this embodiment, the pushing mechanism includes a push block 41 and a push rod 42 disposed on the side of the push block 41 away from the weight sensing module 32. The push rod 42 can reciprocate toward the weight sensing module 32. A linear drive motor 43 is disposed on the side of the push rod 42 away from the push block 41 to drive the push rod 42 in linear reciprocating motion. The linear drive motor 43 is electrically connected to the control module 33. Furthermore, the pushing mechanism includes an operating table 44, which is located on the side of the screening channel 1 away from the discharge channel 2. The push block 41 and push rod 42 are both located on the surface of the operating table 44, and the push rod 42 can extend to the surface of the screening channel 1.

[0031] The bottom of the push block 41 should be polished into a smooth surface so that it can move smoothly on the surface of the operating table 44 or the screening channel 1.

[0032] In this embodiment, the end of the discharge channel 2 close to the screening channel 1 is connected to the side of the screening channel 1 away from the pushing mechanism, and the end of the discharge channel 2 away from the screening channel 1 is arranged vertically downward; and limiting plates 21 are arranged on both sides of the discharge channel 2 to prevent the plastic cups from falling over during the transmission process.

[0033] In this embodiment, the discharge channel 2 is arranged perpendicular to the screening channel 1. A recovery channel 5 is disposed directly opposite the tail end of the screening channel 1. The recovery channel 5 can be a conveyor belt or a recovery basket for recycling unqualified products. It should be noted that to maximize work efficiency and effectiveness, unqualified batches of products discharged from the recovery channel 5 can be further inspected and sorted by traditional individual inspection equipment to prevent qualified products from being mixed with remnants and being recycled and destroyed.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
