Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a food testing line. Background Technology

[0002] Food testing is a discipline that studies and evaluates food quality and its changes, aiming to ensure the safety, nutritional value, and compliance of food through scientific methods. It relies on fundamental principles and techniques of physics, chemistry, and biochemistry, and conducts comprehensive inspections of food raw materials, semi-finished products, finished products, and by-products according to international, national, or industry standards.

[0003] Foreign object detection is a crucial component of food inspection. Common methods for foreign object detection in food include manual sorting, sieve inspection, magnetic separation, metal detection, and X-ray inspection. X-ray food foreign object detection machines are automated foreign object detection devices that have seen widespread adoption in recent years. Utilizing the penetrating power of X-rays, they can detect not only foreign objects in food (such as various meat products, seafood, fruits and vegetables, additives, milk powder, chocolate, etc.), including metals, glass, ceramics, stones, bones, and plastics, but also product defects such as packaging cracks and bubbles, and missing contents, achieving complete finished product inspection. In existing technologies, foreign object detection and outer packaging inspection for food are separate processes, making it impossible to continuously complete multiple inspection stages. Furthermore, conventional food foreign object detection machines have a low degree of automation; loading and unloading are generally done manually, and the connection structure between conveyor sections cannot be adjusted, which to some extent affects overall process efficiency. Summary of the Invention

[0004] This utility model aims to address the technical deficiencies of existing technologies by providing a food inspection line to solve the technical problems of conventional food foreign object detection machines, such as the inability to automate loading and unloading and the inability to adjust the connection structure between conveyor sections.

[0005] Another technical problem that this utility model aims to solve is: how to achieve continuous integration of foreign object detection and other project detection on a single detection line.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0007] A food testing line includes a first frame, a front conveyor, a second frame, a conveyor belt, a testing chamber, an upper belt roller, a lower belt roller, a drive roller, protrusions, crossbars, supports, lock nuts, a base, a first robotic arm, grippers, and a hopper. The front conveyor is mounted on the first frame. Two lower belt rollers and one drive roller are located at the lower part of the second frame. The drive roller is driven by an externally mounted geared motor. Protrusions are fixedly connected to both the front and rear sides of the upper part of the second frame. Crossbars pass through the protrusions and are slidably connected to them. A [missing information - likely a crossbar shape or section] is located in the middle of the crossbar. The external thread has two lock nuts connected to it, which are respectively blocked at the front and rear ends of the protrusion. A bracket is fixedly connected to the crossbar, and an upper belt roller is rotatably connected to the bracket. One of the upper belt rollers is connected to the end of the front conveyor. The conveyor belt is simultaneously wrapped around the outside of the two lower belt rollers, the two upper belt rollers, and a drive roller. A testing chamber is fixedly connected to the upper end of the second frame. A base is provided in front of or behind the testing chamber. A first robot arm is installed on the base. A clamp is provided on the first robot arm. A hopper is provided on the side of the testing chamber.

[0008] Preferably, the first frame and the second frame each include several supports, and cross frames are connected between the supports.

[0009] Preferably, the clamp is a pneumatic gripper or an electric gripper.

[0010] Preferably, a temporary storage platform is also included, which is located on the side of the front conveyor and has several storage slots.

[0011] Preferably, the system also includes a second testing station, a frame, and mechanical pressure heads. The second testing station is located in front of the conveyor belt, and a frame is provided on the side of the second testing station. Several mechanical pressure heads are provided on the frame.

[0012] Preferably, an extension conveyor is provided in front of the conveyor belt, and a second robotic arm and a third inspection station are provided on the side of the extension conveyor.

[0013] Preferably, there are several cargo boxes, all of which are located within the range of motion of the first robotic arm.

[0014] In the above technical solution, the first frame supports the front conveyor, serving as the conveying section for the sample before it enters the testing area. The second frame houses the conveyor belt, with the upper belt roller, lower belt roller, and drive roller all located within its operating range. The drive roller is driven by an external geared motor, providing power for the conveyor belt's operation, while the upper and lower belt rollers support the conveyor belt's operating range. The lower belt roller and drive roller can be mounted on the second frame, while the upper belt roller is mounted on a support. Since the crossbar at the rear of the support can slide on a protrusion and be locked in place by a lock nut, the position of the upper belt roller can be controlled. This adjustment of the upper belt roller's position can control the tension of the conveyor belt to a certain extent and reduce the gap between adjacent conveyor belts, achieving better connection between them. The upper surface of the conveyor belt carries the sample through the testing chamber for testing. The base is used to mount the first robotic arm, which positions the clamps at its end, allowing for loading and unloading. The hopper can be used for receiving materials.

[0015] In the preferred technical solution, the temporary storage table can be used to place the samples to be inspected; the second inspection table can be used to perform mechanical inspection on the outer packaging, applying external force using the mechanical pressure head on the table; in addition, an extension conveyor, a second robot and a third inspection table can be added to perform other inspection items.

[0016] This invention provides a food inspection line. This technical solution not only achieves continuous integration of foreign object detection and other inspection items on a single inspection line, but also designs an adjustment mechanism for the conveyor belt rollers, thereby enabling adjustment of the connection structure between conveyors. Furthermore, this invention adds a robotic arm and clamps to assist in loading and unloading, improving the automation level of the inspection line to a certain extent. Attached Figure Description
