Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating production line technology, and in particular to a safety detection and intelligent protection device for coating drying room equipment. Background Technology
[0002] The drying chamber of a large-scale coating production line poses significant safety hazards, including chain breakage and tooling tipping due to equipment jamming. The high temperature within the drying chamber prevents personnel from entering during production for inspection and troubleshooting. Therefore, a detection device is designed inside the drying chamber to identify these hazards. A position detection switch is installed on the conveyor system inside the drying chamber. If mechanical failures such as jamming occur, the conveyor will stop operating after a delay. However, the detection switch and its cables are located inside the drying chamber, where the high temperature and humidity can easily damage them, causing the detection function to fail. This creates a hazard in the conveyor control system, but since the detection is ineffective, the drive power source will not be cut off until the chain breaks. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] like Figure 1-2As shown: A safety detection and intelligent protection device for coating drying chamber equipment includes a main support 5, a push rod 8, a roller 2, and a sensor 12. A roller 2 is rotatably mounted on the top of the first end of the main support 5, a push rod 8 is slidably mounted on the top of the middle end of the main support 5, and a sensor 12 is mounted on the top of the second end of the main support 5. When the first end of the push rod 8 rolls with the roller 2, the second end of the push rod 8 blocks the sensor 12. If the conveying equipment in the coating drying chamber overtravels, jams, or over-positions, it will collide with the detection roller 2, causing the detection push rod 8 to move forward and block the signal from the sensor 12. The conveying system will immediately cut off the power supply to protect the conveying equipment (such as conveyor chains, roller beds, transplanters, etc.), effectively preventing major equipment failures such as chain breakage and platform tipping. The protection efficiency can reach 100%, significantly reducing equipment maintenance and labor costs.
[0020] Roller 2 is located inside the drying chamber, while sensor 12 is located outside. The detection sensor, transmitted to the outside via a mechanical device, can respond quickly and cut off the power supply. This not only avoids the risk of damage to the detection system operating in high-temperature and high-humidity environments but also solves the problem of frequent production line failures caused by the failure of the detection system inside the drying chamber. Personnel can conveniently patrol, inspect, and test the line from outside the drying chamber daily, ensuring the effectiveness and integrity of the sensors.
[0021] It also includes a roller bracket; the roller bracket includes a side U-shaped frame 1, a pin 3, and a guide rod 4; the side U-shaped frame 1 is connected to the roller 2 via the pin 3, the first end of the guide rod 4 is connected to the side U-shaped frame 1, and the second end of the guide rod 4 is connected to the main bracket 5. The roller bracket is used to further install the roller 2 according to the structure of the main bracket 5.
[0022] It also includes a coupling 9; the push rod 8 is also equipped with a coupling 9. It interacts with the mechanical equipment by connecting the coupling 9 and the push rod 8.
[0023] It also includes a return elastic positioning device 13; the return elastic positioning device 13 is located between the roller 2 and the first end of the push rod 8. After the conveying system is restored, the conveying equipment disengages from the roller 2, and the roller 2 returns to its original position through the return elastic positioning device 13, ensuring the accuracy of the detection position. The return elastic positioning device 13 can be a spring.
[0024] It also includes a push head 10; the push head 10 is provided on the second end of the push rod 8. The push head 10 is set in accordance with the signal source of the sensor 12 to further block the sensor signal.
[0025] It also includes a sensor bracket 11; the main bracket 5 is equipped with the sensor bracket 11, and the sensor 12 is mounted on the sensor bracket 11. The sensor bracket 11 is used to further mount the sensor 12 according to the structure of the main bracket 5.
