This utility model discloses a retractable miniature temperature sensor detection head structure, relating to the technical field of temperature sensor detection heads. It includes a housing with a telescopic shell inserted at one end. Inside the housing is a pneumatic assembly for driving the telescopic shell's vertical movement. Inside the telescopic shell is a thermistor element, with a lead wire body on one side of the thermistor element. Inside the housing is a winding assembly to prevent the lead wire body from tangling during the telescopic shell's vertical movement. This utility model uses a pneumatic assembly to drive the detection head's extension and retraction. A sealing ring on the outer circumference of the piston body ensures the housing's internal sealing, preventing gas leakage and insufficient driving force for extension and retraction, thus ensuring stable operation of the extension function. Simultaneously, a limiting ring plate inside the housing prevents the piston body from overtraveling, effectively protecting the structure of each component, reducing wear caused by excessive component movement, and extending the overall device's service life.

This invention relates to the field of tofu skin processing equipment, and particularly to a tofu skin rolling mechanism, comprising a disc frame, a guide assembly, and a rolling drum. The disc frame is evenly distributed with clamping assemblies driven to rotate by a chain drive assembly. Each clamping assembly includes a sleeve rotatably connected to a fixed base. The sleeve has a sprocket A, and two parallel-opening and closing clamping handles at its front end. The chain drive assembly includes a chain rotatably mounted on a mounting beam. A fan-shaped plate is located at the front end of the mounting beam, and several rollers coaxially arrayed relative to the disc frame are rotatably connected to the fan-shaped plate. These rollers are used to tension the chain. The chain on one side of each roller meshes with sprocket A. The guide assembly includes an arc-shaped guide groove. By cooperating with sprocket A and the guide groove, the tofu skin can be pre-rolled and formed, preventing scratches and damage upon entering the rolling drum. The parallel opening and closing of the clamping handles prevents the tofu skin roll from being stretched open, thereby improving the overall quality of the tofu skin roll.
