Description

Technical Field

[0001] This utility model relates to the technical field of bottom cover production equipment, and more specifically, to an automatic power-off device for a bottom cover drying oven. Background Technology

[0002] Bottom cover production drying ovens are specialized equipment used for drying, curing, or heat-treating bottom covers, such as container bottom covers. Their main function is to ensure that the bottom covers achieve the required drying, curing, or performance optimization effects during the production process by controlling conditions such as temperature, humidity, and ventilation. Drying ovens are typically used to remove moisture, cure coatings, or perform heat treatment to improve the strength, durability, and surface quality of the bottom covers. Currently, bottom cover production drying ovens lack automatic power-off functions. If a problem occurs during production and the machine stops, the oven continues to heat, causing the bottom covers to overheat and become unusable, resulting in significant waste. Utility Model Content

[0003] To overcome the shortcomings of existing technology, this utility model provides an automatic power-off device for a bottom-cover oven.

[0004] This utility model is achieved through the following technical solution: an automatic power-off device for a bottom-cover oven, comprising a bottom-cover oven body, a conveyor belt, and a conveyor belt support. The conveyor belt is installed on the top of the conveyor belt support, and the bottom-cover oven body is installed on the middle of the conveyor belt. Baffle limiting mechanisms are respectively provided above the front and rear ends of the conveyor belt. An infrared distance sensor is provided above the inlet of the bottom-cover oven body, and the infrared distance sensor is 20cm away from the inlet of the bottom-cover oven body. A PLC controller is installed on one side of the bottom-cover oven body, and the PLC controller is communicatively connected to the infrared sensor and the bottom-cover oven body.

[0005] As a preferred embodiment, the baffle limiting mechanism includes a left baffle, a right baffle, a telescopic push rod, and a push rod base. The telescopic push rod is fixedly and horizontally installed on the outer side of both the left and right baffles, and the end of the telescopic push rod is fixedly installed on the conveyor belt bracket through the push rod base.

[0006] As a preferred option, the infrared distance sensor is mounted on an L-shaped bracket, the lower end of which is fixedly mounted on a mounting plate, which is then fixedly mounted on the conveyor belt bracket with bolts.

[0007] This utility model, by adopting the above technical solution, has the following beneficial effects compared with the prior art: a sensor is installed in front of the bottom cover production drying room. If the sensor fails to detect the bottom cover entering, the drying room will automatically cut off the power to prevent the product from burning.
