Description

Technical Field

[0001] This utility model relates to the field of bread production, and in particular to a conveying mechanism with detection function for bread production. Background Technology

[0002] The conveyor system in bread production is the "logistics backbone" that runs through the entire production line. Its core function is to transfer bread stably, efficiently, and without damage between different processes, while ensuring the shape, order, and hygiene of the products. Bread is a food that is easily deformed, easily contaminated, and has a short shelf life. If defective products flow into subsequent processes, it may lead to the scrapping of the entire batch or even a food safety incident. On the bread production line, the conveyor system must integrate detection functions.

[0003] During the bread production stage, photoelectric sensors or vision systems are used to detect abnormal spacing in the dough, 3D cameras scan the height / width of the dough, metal detectors or X-ray machines are used to detect metal fragments mixed into the bread, and finally, non-destructive testing is performed on the bread to detect issues such as uncooked cores, stones, and plastic.

[0004] In existing technologies, bread is inspected using various optical inspection devices. However, bread production lines typically contain flour dust, which floats in the air during transport and inspection, leading to a decrease in inspection accuracy and consequently reducing the quality of bread production. Therefore, a conveyor mechanism with inspection function for bread production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a conveying mechanism with detection function for bread production, which aims to improve the problem that existing conveying mechanisms with detection function for bread production lack shielding against flour dust during conveying and detection, thus reducing detection accuracy.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a conveying mechanism with detection function for bread production, including a support frame 1. Baffles are provided on the top of both sides of the support frame 1. A conveyor belt 2 is provided on the surface of the support frame 1. The conveyor belt 2 is driven by a motor-driven reducer, which in turn drives a transmission shaft to move the conveyor belt 2. A slot 3 is provided on the top of the support frame 1. No baffles are provided on either side of the slot 3, providing a position for the installation of a bracket 4. The bracket 4 is inserted into the inner wall of the slot 3. The bracket 4 is arranged in an inverted U-shape. A detection camera 16 is fixedly connected to the inner surface of the bracket 4. The detection camera 16 detects the bread using infrared detection, non-destructively detecting foreign objects or quality abnormalities inside the bread. The detection camera 16 uses near-infrared spectral imaging technology, with a working wavelength of 900-1700nm. The bread surface is irradiated by a halogen light source, and the camera captures the reflected spectrum. When any of the following conditions are detected, the product is judged as unqualified: foreign object detection is performed at 1550-1650nm. An abnormal reflection peak appears in the nm band, corresponding to plastics. In quality inspection, the internal pore uniformity is <85% or the surface charring area is >15% of the surface area. The detection signal is processed by a PLC controller with a sampling frequency of 120 frames / second. An air pump 5 is fixedly connected to the top of the bracket 4. A three-way pipe 6 is fixedly connected to the output end of the air pump 5. Fixed pipes 7 are fixedly connected to both ends of the three-way pipe 6. The two ends of the fixed pipes 7 are sealed. A metering valve 9 is fixedly connected to the lower end of the circumferential surface of the fixed pipe 7 through a pipe. A diverter pipe 8 is fixedly connected to the end of the metering valve 9. A cavity 10 is opened in the inner wall of the bracket 4. The bottom end of the diverter pipe 8 penetrates into the cavity 10. A conical hole 11 is opened in the outer wall of the bracket 4. The conical hole 11 is connected to the cavity 10. The conical hole 11 can expand the air outlet area of ​​the low-pressure air source. Multiple sets of equidistant conical holes 11 form a low-pressure air curtain on both sides of the bracket 4, effectively blocking external dust from entering the detection area and avoiding interference from flour dust in the bread production line.

[0033] Reference Figures 3-5The surface of the support 4 is provided with a rejection assembly, which includes an air outlet 13, an opening 14, a discharge plate 15, an electric push rod 17, a guide rod 18, a push plate 19, and a transmission pipe 12. The air outlet 13 is opened on the outer wall of the support 4 near the opening 14. The opening 14 is opened through the outer wall of the support 4, allowing bread that fails the inspection to be moved from the conveyor belt 2 onto the discharge plate 15. The discharge plate 15 is fixedly connected to the outer wall of the support 4. The discharge plate 15 is set in a downward inclined position, which helps the bread fall quickly into the external collection box. The discharge plate 15 is located at the bottom end of the air outlet 13. The electric push rod 17 is fixedly connected to the outer wall of the support 4. The output end of the electric push rod 17 is fixedly connected to the outer wall of the support 4. A push plate 19 is fixedly connected to the support 4, and a guide rod 18 is fixedly connected to the side wall of the push plate 19. The guide rod 18 passes through one side outer wall of the support 4 and is slidably connected to the inner wall of the support 4. Two sets of guide rods 18 are provided and are located on the left and right sides of the electric push rod 17 to ensure the stability of the push plate 19. The push plate 19 is U-shaped and can avoid touching the detection camera 16 when pushing unqualified bread. A transmission pipe 12 is fixedly connected to the end of the fixed pipe 7. The inner wall of the transmission pipe 12 is fixedly connected to the inner wall of the air outlet 13 through the pipe. The transmission pipe 12 is U-shaped and its two ends pass through the ends of the two sets of fixed pipes 7 to lead out the air source inside and prevent dust from entering the support 4 through the opening 14.

[0034] Reference Figures 4-5 The outer wall of the bracket 4 is fixedly connected to a protruding plate 20, and the bottom of the protruding plate 20 is fixedly connected to an electromagnetic base 21. The outer wall of the support frame 1 is provided with an embedding groove 22, and the inner wall of the embedding groove 22 is fixedly connected to a loop electromagnet 23. The inner surface of the loop electromagnet 23 is adapted to the outer wall of the electromagnetic base 21. The electromagnetic base 21 and the loop electromagnet 23 are conductive electromagnets. When the two are energized, the magnetic attraction force generated can increase the stability of the bracket 4 on the support frame 1. The protruding plate 20, the electromagnetic base 21, the embedding groove 22 and the loop electromagnet 23 are respectively arranged in two sets, located on both sides of the support frame 1 and the bracket 4.

[0035] Working principle: A motor drives a reducer, which in turn drives the transmission shaft to rotate, thereby driving the conveyor belt 2 to continuously transport bread on the support frame 1. Baffles on both sides of the support frame 1 limit the bread's movement during transport, preventing it from shifting. When the bread reaches the detection area below the bracket 4, the detection camera 16 on the inner surface of the bracket 4 activates, using infrared non-destructive testing technology to detect foreign objects or quality abnormalities inside the bread. Simultaneously, the air pump 5 at the top of the bracket 4 operates, and its output airflow is diverted through a three-way pipe 6 to fixed pipes 7 on both sides. Part of the airflow in the fixed pipe 7 is regulated by a metering valve 9 and enters a diversion pipe 8, then enters the cavity 10 of the bracket 4 through the bottom of the diversion pipe 8, and finally exits from the conical holes 11 on the outer wall of the bracket 4. Multiple sets of equidistantly arranged conical holes 11 diffuse the airflow, forming a low-pressure air curtain on both sides of the bracket 4, effectively blocking external dust from entering the detection area and preventing flour dust from interfering with the detection accuracy. When the inspection camera 16 detects defective bread, the rejection assembly starts working. Another part of the airflow generated by the air pump 5 is delivered to the air outlet 13 through the transmission pipe 12. The air outlet 13 sprays air towards the opening 14 to provide auxiliary airflow for the removal of defective bread. At the same time, the electric push rod 17 is activated, and its output end pushes the push plate 19 to move. The guide rod 18 ensures that the push plate 19 slides stably. The U-shaped push plate 19 pushes the defective bread from the conveyor belt 2 through the opening 14 to the inclined discharge plate 15. The bread slides down the discharge plate 15 to the external collection box. In addition, the bracket 4 is attracted by the electromagnetic base 21 at the bottom and the circular electromagnet 23 embedded in the groove 22 of the support frame 1 through power-on. The two sets of symmetrically arranged electromagnetic structures greatly improve the installation stability of the bracket 4 on the support frame 1, ensuring the accurate operation of the detection and rejection process. The entire mechanism realizes quality control on the bread production line through the coordinated work of detection, protection and rejection.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
