DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0023] When adjusting the tightness of the Teflon high-temperature cloth conveyor belt, the two dual-axis motors 21 on the support plate 15 drive the top taps 222 of the output shafts on both sides to rotate, so that the tap gear 223 rotates. Since the fixed sleeve 224 and the lifting device housing 221 limit the tap gear 223, the support rod 225 moves up and down, thereby adjusting the height of the tensioning rollers 24 on the two brackets 23, thereby adjusting the tightness of the conveyor belt 13.

Since the fixed sleeve 224 and the lifting device housing 221 limit the tap gear 223, the support rod 225 moves up and down, thereby adjusting the height of the tensioning rollers 24 on the two brackets 23, so as to adjust the tightness of the conveyor belt 13. When the equipment is operating, the motor 251 will operate regularly, so that the threaded rod 252 rotates to drive the detection device housing 255 is raised and lowered. When it reaches the highest point, the bottom of the conveyor belt 13 will squeeze the slider 2513. After the airbag 2512 shrinks, the gas enters the inner cavity of the detection device housing 255 through the air guide tube 2511. The diaphragm 259 squeezes the piezoelectric element 258 due to the change in air pressure. The piezoelectric element 258 will generate current at this time. Under the action of the lead 257, the current is conducted to the current measuring device 256. The tightness of the conveyor belt 13 is judged by analyzing the current size to control the operation of the dual-axis motor 21, so as to automatically control the tightness of the Teflon high-temperature cloth conveyor belt.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
