[0021] The technical solution adopted above draws water from the water chamber 5 through the water pump 11 and then sprays it out from the nozzle 10. The water sprayed by the nozzle 10 cools the surface of the roller assembly 2, thereby preventing the roller assembly 2 from aging and damage due to frictional overheating and extending its service life.

[0022] The roller assembly 2 includes roller frames 15 symmetrically arranged on both sides of the frame 1, a plurality of rollers 16 are installed between the ends of the two roller frames 15, a crossbeam 19 is installed between the two roller frames 15 and below the rollers 16, the support plate 8 is located below the crossbeam 19, a heat-conducting seat 18 is installed in the middle of the top of the crossbeam 19, the top of the heat-conducting seat 18 is an arc surface, and contacts with one of the rollers 16 through the arc surface, and a temperature sensor 17 is embedded on the side of the heat-conducting seat 18;

[0023] The technical solution adopted above is that the heat-conducting seat 18 contacts the middle roller 16, so that the heat generated by the roller 16 will be transferred to the heat-conducting seat, and then the temperature of the heat-conducting seat 18 is measured by the temperature sensor 17, thereby indirectly measuring the temperature of the roller 16.

[0025] In the technical solution adopted above, the top of the guide seat 4 is located on both sides of the guide groove 20 and is an inclined surface. The guide groove 20 can receive water sprayed on the conveying tape 3 and falling on it. The filter plate 21 can isolate larger debris from entering the guide groove 20. The water entering the guide groove 20 will pass through the filter net 22 and re-enter the water cavity 5 to be collected, thereby saving water resources.

The temperature receiver is used to receive the temperature of the roller 16 measured by the temperature sensor 17. The temperature comparator will compare the preset comparison value with the measured temperature. When the measured temperature is greater than the preset value, the signal will be sent to the controller through the signal generating circuit and the signal transmitter. After receiving the signal, the controller will send a control signal to the solenoid valve and the water pump to start them and spray water through the nozzle 10 to cool the roller 16. The above can be further improved with reference to the existing technical control means.
