[0026] The temperature compensation component 4 includes a communication box 401 provided on one side of the conductive rail body 1, side pipes 402 are equidistantly installed on the side of the communication box 401 close to the conductive rail body 1, the side pipes 402 are communicated with one end of the flow-through groove 3, a fan box 404 is provided below the communication box 401, the fan box 404 is used to drive the outside air to continuously pass through the conductive rail body 1, and a temperature control member is provided between the communication box 401 and the fan box 404.
[0027] The temperature control component includes a second connecting pipe 405 fixedly installed at the top of the blower box 404. A first connecting pipe 403 is fixedly installed at the bottom of the communication box 401. A processing box 406 is provided between the first connecting pipe 403 and the blower box 404. Flow control boxes 407 are symmetrically arranged on the upper and lower sides of the processing box 406. The upper and lower flow control boxes 407 are respectively communicated with the first connecting pipe 403 and the second connecting pipe 405. A heating chamber 409 and a refrigerating chamber 410 are formed inside the processing box 406. A heater is installed inside the heating chamber 409, and a refrigerator is installed inside the refrigerating chamber 410. Heat insulation pads are installed on the inner walls of both the heating chamber 409 and the refrigerating chamber 410. C-shaped pipes 408 are symmetrically installed on both sides of the processing box 406. The C-shaped pipes 408 on both sides are respectively communicated with the heating chamber 409 and the refrigerating chamber 410. A temperature sensor 2 is arranged on the conductive rail body 1 to detect the temperature of the conductive rail body 1. When the blower box 404 is turned on, it drives the outside air to continuously pass through the flow grooves 3 arranged at equal intervals on the conductive rail body 1. At the same time, when the air passes through the heating chamber 409 and the refrigerating chamber 410, it can heat and cool the air respectively. Thus, when the processed air passes through the flow grooves 3, it compensates the temperature of the conductive rail body 1, facilitating use at different temperatures.

When the heating chamber 409 or the refrigerating chamber 410 is in use, the corresponding cylinder 417 on that side needs to be turned on to pull the movable plate 413 to move, so that the second through holes 414 on the movable plate 413 correspond to the first through holes 412 on the fixing plate 411, enabling the air to pass through the heating chamber 409 or the refrigerating chamber 410 smoothly, facilitating the corresponding treatment of the air and facilitating the temperature compensation of the conductive rail body 1.
[0028] Working principle: During operation, first, a temperature sensor 2 is arranged on the conductive rail body 1, and the temperature sensor 2 can detect the temperature of the conductive rail body 1;
[0029] When the temperature of the conductive rail body 1 is relatively high, the controller controls the cooler in the refrigeration chamber 410 to turn on. At the same time, the cylinder 417 on the side close to the refrigeration chamber 410 is turned on to pull the movable plate 413 to move, so that the second through hole 414 on the movable plate 413 corresponds to the first through hole 412 on the fixed plate 411. The blower box 404 is turned on to drive the outside air to enter the communication box 401 through the refrigeration chamber 410 and continuously pass through the flow grooves 3 equidistantly arranged on the conductive rail body 1. After the air passes through the inside of the refrigeration chamber 410, its temperature is lowered under the action of the cooler, and then the conductive rail body 1 is cooled down;
[0030] When the temperature of the conductive rail body 1 is relatively low, the controller controls the heater in the heating chamber 409 to turn on. At the same time, the cylinder 417 on the side close to the heating chamber 409 is turned on to pull the movable plate 413 to move, so that the second through hole 414 on the movable plate 413 corresponds to the first through hole 412 on the fixed plate 411. The blower box 404 is turned on to drive the outside air to enter the communication box 401 through the heating chamber 409 and continuously pass through the flow grooves 3 equidistantly arranged on the conductive rail body 1. After the air passes through the inside of the heating chamber 409, its temperature is raised under the action of the heater, and then the conductive rail body 1 is heated.
