Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a card holder. Background Technology

[0002] In recent years, with the rapid development of the snack food industry, the market demand for small-packaged foods such as quail eggs and nuts has increased significantly. These products require strict foreign object detection procedures during production, such as identifying impurities like eggshell fragments and hair using visual inspection systems, and accurately removing defective products using pneumatic devices. However, existing conveying technologies generally use flat belts or synchronous belts as carriers, which have significant drawbacks in practical applications: First, the low surface friction coefficient of the belts makes it easy for materials to slip or deviate during high-speed conveying or sudden stops, leading to inaccurate visual inspection positioning and resulting in false rejections or missed detections; second, after long-term operation, the belts are prone to loosening, wear, or surface aging, further exacerbating the slippage problem, requiring frequent shutdowns to adjust tension or replace the belts, severely impacting production efficiency; third, the belt material has high elasticity, and materials may sway in the detection area due to belt vibration or deformation, affecting image clarity and detection accuracy.

[0003] To address these issues, the industry has attempted to improve solutions, such as adding anti-slip textures to the conveyor belt or employing vacuum adsorption technology. However, anti-slip textures are prone to wear and failure, and vacuum adsorption systems are complex in structure and consume a lot of energy. Another technical solution proposes using a chain conveyor structure, which uses rigid chain plates to fix materials. However, the gaps between the chain links can easily trap packaging film or debris, leading to equipment jamming and malfunctions, and a sharp increase in maintenance costs. In addition, some high-end equipment has introduced servo-driven independent fixture positioning technology, which can improve accuracy, but suffers from high costs and poor compatibility (only suitable for materials of specific sizes), making it difficult to popularize in small and medium-sized enterprises.

[0004] Currently, with increasingly stringent food safety regulations and rising consumer demands for quality, the industry is setting higher standards for the positioning accuracy, operational stability, and ease of maintenance of conveying systems. Especially in high-speed continuous production, achieving "zero-displacement" material conveying, reducing false rejection rates, and minimizing downtime for maintenance have become key bottlenecks restricting technological upgrades in the industry. Therefore, there is an urgent need for a conveying device that is simple in structure, cost-effective, and highly adaptable to address the inherent shortcomings of existing technologies and meet the core needs of automated testing production lines.

[0046] The card holder body 2 is made of polypropylene or nylon.

[0047] The card holder body 2 has a card hole 21 on its side for installation with the chain pin, so that the card holder body 2 is fixed on the conveyor chain 1.

[0048] The card holder body 2 is made of plastic injection molding. The material support platform 22 at the top is provided with a spherical recess 23.

[0049] The material body 3 is placed on the support platform 22, and the conveyor chain 1 drives the card holder body 2 to convey the material body 3 through the detection mechanism for visual inspection.

The distance from the photoelectric switch to the camera detection area is set as X, and the distance from the detection area to the nozzle of the blower outlet is set as Y. The material conveyed by the cassette is numbered after passing through the induction switch. After the detection is completed, it arrives at the nozzle area for sorting and rejection.

[0054] It also includes an encoder, which is linked to the conveyor chain 1 to monitor the chain displacement in real time and achieve precise positioning control for material sorting.

[0055] The card holder body 2 is detachably fixed to the conveyor chain 1 by a chain pin, and the gap between the serrated structure 24 between adjacent card holder bodies 2 is ≤0.2mm.

[0056] Step 1: Assembly of the card holder body and the conveyor chain

[0057] Card holder body structure: The card holder body 2 is made of plastic injection molding (the material is polypropylene or nylon, which is corrosion resistant and meets food-grade requirements). Its bottom is provided with a groove 25, which engages with the chain links of the conveyor chain 1 through the groove 25 to achieve quick installation.

[0058] Fixing method: The card hole 21 on the side of the card holder body 2 cooperates with the chain pin of the conveying chain 1. The circumferential fixation of the card holder body 2 is completed by inserting the pin into the card hole 21 to ensure that there is no slippage during the conveying process.

[0059] Base installation: The conveyor chain 1 is installed on the base 4 as a whole. The base 4 is fixed to the equipment frame by bolts. The chain is driven by the drive sprocket and moves smoothly in the guide groove of the base 4.

[0060] Step 2: Material support platform and limiting structure

[0061] Spherical recess design: The surface of the support platform 22 at the upper end of the card holder body 2 is provided with a spherical recess 23. The inner wall of the recess is coated with a food-grade silicone layer (thickness 0.5-1mm), which is achieved by in-mold injection molding or secondary spraying process. The silicone layer can increase friction and buffer vibration to prevent material from rolling and shifting.

[0062] Serrated meshing structure: The contact edges of adjacent card holder bodies 2 are machined into a serrated structure 24. During installation, the serrations are ensured to mesh with each other with a gap of ≤0.2mm, which effectively prevents packaging film or foreign objects from getting stuck in the gap and reduces the frequency of downtime for cleaning.

[0063] Step 3: Integration of Conveying and Detection Systems

[0064] Visual inspection process: The material body 3 (such as packaged quail eggs) is placed in the spherical recess 23, and the conveyor chain 1 drives the card holder through the inspection area at a constant speed.

[0065] Positioning control: An encoder is installed on the base 4 to monitor the chain displacement in real time; a photoelectric switch triggers the camera to take a picture at a set distance X. After detecting foreign objects, the system controls the nozzle to accurately remove defective products at a distance Y according to the encoder signal.

[0066] Stability verification: Operational tests show that the chuck does not slip within a speed range of 0.5 to 1.2 m / s, the material displacement is <0.1 mm, and the sorting accuracy is ≥99.5%.

[0067] Step 4: Maintenance and Optimization

[0068] Quick Replacement: To replace the card holder body 2, simply pull out the chain pin to disassemble it. The groove 25 design supports modular replacement.

[0069] Cleaning and maintenance: The food-grade silicone layer can be washed directly with water, and the serrated structure reduces dirt buildup, extending the maintenance cycle to more than 200 hours.

[0070] The foregoing has provided a detailed description of one embodiment of the present invention, but the description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the scope of the claims of the present invention.
