Description

Technical Field

[0001] This invention relates to the field of baking pan performance testing technology, specifically a device for testing the thermal conductivity of baking pans. Background Technology

[0002] Baking refers to the process of dehydrating, drying, and hardening materials by applying dry heat below their ignition point. Baking is an indispensable step in the production of bread and cakes. Through baking, starch undergoes gelatinization, protein denaturation, and a series of chemical changes, resulting in the ripening of bread and cakes and altering their texture.

[0003] Baking pans possess excellent thermal conductivity, and the good plasticity of metal pans allows for easy die-casting into various desired shapes. They are widely used in pastry preparation to produce pastries of various shapes. Better thermal conductivity in the pan, coupled with higher oven power, results in faster baking and lower energy consumption. Therefore, the thermal conductivity of the baking pan has a significant impact on energy saving, necessitating testing of its thermal conductivity. However, the devices used for testing the thermal conductivity of baking pans often contain high-temperature gases. These devices typically lack adequate protective measures, requiring personnel to operate them in an environment emitting these high-temperature gases, increasing the risk of burns. Existing testing devices lack adequate personnel protection. Summary of the Invention

The pushing and closing mechanism then moves the tray support frame, simultaneously sealing the feed box and no longer obstructing the guide cavity. A magnetic moving mechanism then transfers the baking tray from the tray support frame into the guide cavity, where it slides into the inclined cavity. Finally, the baking tray falls onto the heating and testing structure for testing. The tested baking tray is then poured into the workpiece cooling structure. This invention, by sealing one end of the guide cavity with the pushing and closing mechanism, prevents personnel from being burned by hot air when adding the baking tray. When the pushing and closing mechanism does not seal the guide cavity, it seals the opening of the feed box, thus protecting personnel safety during the addition of the testing baking tray.

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] Example 1

[0027] See Figures 1-6 As shown, a baking pan thermal conductivity testing device includes a testing chamber 1, with an inclined cavity 2 inside the testing chamber 1, and further includes:

[0028] The heating detection structure 3 is installed inside the detection box 1, and the heating detection structure 3 is set inside the inclined cavity 2;

[0029] Workpiece cooling structure 4 installed inside the inspection box 1;

[0030] A feeding structure 5 is installed on one side of the detection box 1. The feeding structure 5 includes a feeding box 6 fixedly connected to the detection box 1. An inclined guiding cavity 7 is opened in the feeding box 6. The guiding cavity 7 is connected to the inclined cavity 2. A magnetic suction moving mechanism 8 is installed in the feeding box 6. A pushing and closing mechanism 9 is slidably connected to the feeding box 6. A baking tray support frame 10 is fixedly connected to the pushing and closing mechanism 9.

[0031] Control console 32 is installed on one side of the feed hopper 6.

[0032] When the baking tray to be tested is placed on the baking tray support frame 10, the pushing and closing mechanism 9 closes one end of the guide cavity 7, thus preventing excessive overflow of high-temperature gas from the heating detection structure 3 from the guide cavity 7. Then, the pushing and closing mechanism 9 moves the baking tray support frame 10. During this process, the pushing and closing mechanism 9 closes the feed box 6 while no longer blocking the guide cavity 7. Then, the magnetic moving mechanism 8 transfers the baking tray from the baking tray support frame 10 into the guide cavity 7. The baking tray then slides along the guide cavity 7 into the inclined cavity 2. Finally, the baking tray falls onto the heating detection structure 3 for testing. After testing, the baking tray is poured into the workpiece cooling structure 4. In use, the present invention seals one end of the material guiding cavity 7 by pushing and closing mechanism 9, thereby preventing personnel from being burned by hot air when adding baking trays. When the pushing and closing mechanism 9 does not seal the material guiding cavity 7, it seals the opening of the feeding box 6, thus making it less likely for personnel to be burned during the process of adding baking trays for testing, thereby protecting personnel safety.

[0033] In one embodiment, the pushing and closing mechanism 9 includes multiple sets of sliding rods 11 slidably connected to the feeding box 6. Each sliding rod 11 is fixedly connected to a groove plate 12, which is slidably connected to the feeding box 6. The groove plate 12 has a Z-shaped groove 13 at the beginning, and a short rod 14 is slidably connected to the Z-shaped groove 13. A connecting strip 15 is fixedly connected to the short rod 14, and a cover plate 16 slidably connected to the feeding box 6 is fixedly connected to the connecting strip 15. A magnet is installed on the side of the cover plate 16 facing the feeding box 6, and a push-pull bracket 39 is fixedly connected to the cover plate 16. A heat insulation plate 17 adapted to the guiding cavity 7 is fixedly connected to the groove plate 12. The area of ​​the heat insulation plate 17 is larger than the area of ​​the guiding cavity 7 facing the heat insulation plate 17. The heat insulation plate 17 is slidably connected to the inner wall of the feeding box 6 and fixedly connected to the baking tray support frame 10. When the cover plate 16 is pushed to move, the connecting bar 15 drives the short rod 14 to move, and the moving fixed short rod 14 drives the slot plate 12 to move, thereby driving the heat insulation plate 17 to move. As the heat insulation plate 17 moves, the baking tray support frame 10 moves accordingly. When the cover plate 16 covers the opening of the feed box 6, the slot plate 12, the heat insulation plate 17, and the baking tray support frame 10 are all in a low position, and the heat insulation plate 17 no longer blocks the guide cavity 7.

[0034] In one embodiment, the baking tray support 10 has a slot 18. The slot 18 is used to limit the position of the baking tray.

[0035] In one embodiment, the magnetic moving mechanism 8 includes a first motor 19 fixedly connected to the feed box 6 and a machine cover 20. A first gear 21 is fixedly mounted on the output shaft of the first motor 19. The first gear 21 is meshed with a second gear 22 rotatably connected to the machine cover 20. A lead screw 23 is fixedly connected to the second gear 22 and rotatably connected to the machine cover 20. The lead screw 23 is threadedly connected to a sliding arm 24 slidably connected to the feed box 6. An electromagnet 25 is fixedly connected to the sliding arm 24. The first motor 19 drives the first gear 21 to rotate. Under the transmission of the second gear 22, the lead screw 23 rotates and drives the sliding arm 24 to slide, thereby causing the electromagnet 25 to move towards the baking tray. After the electromagnet 25 magnetically attracts the baking tray, the sliding arm 24 returns to its original position, and the electromagnet 25 is de-energized, placing the baking tray into the guide cavity 7. The baking tray then slides into the detection box 1.

[0036] In one embodiment, the heating detection structure 3 includes a second motor 26 fixedly connected to the detection box 1. The output shaft of the second motor 26 is fixedly connected to a rotating frame 27, and the rotating frame 27 is fixedly connected to a heating base 28. A heating rod 29 is fixedly installed inside the heating base 28, and a reflector 30 is fixedly installed inside the heating base 28. An infrared camera 31 is fixedly installed inside the detection box 1, with one end of the infrared camera 31 facing the heating base 28 and extending into the inclined cavity 2. After the baking tray slides onto the rotating frame 27, the heating rod 29 heats one side of the baking tray. The infrared camera 31 then performs real-time infrared imaging of the heated baking tray to determine the heat conduction rate at different locations on the baking tray.

[0037] In one embodiment, the workpiece cooling structure 4 includes an air inlet cavity 33 within the inspection chamber 1. The air inlet cavity 33 is connected to a storage cavity 34 within the inspection chamber 1. A perforated plate 35 is fixedly installed within the storage cavity 34. A fan 36, fixedly connected to the inspection chamber 1, is located on one side of the perforated plate 35. The inspection chamber 1 is movably connected to a door 37. After the baking tray is inspected, the second motor 26 drives the rotating frame 27 to rotate, thereby releasing the baking tray into the storage cavity 34. Then, under the suction of the fan 36, air flows within the storage cavity 34, thereby cooling the baking tray on the perforated plate 35.

[0038] Example 2

[0039] Based on Example 1, see [link / reference] Figure 2 A filter 38 is installed inside the air inlet cavity 33. The filter 38 is used to filter the air flowing through the air inlet cavity 33 to prevent dust from entering the storage cavity 34.

[0040] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
