The utility model discloses a kind of high-pressure wind grid transmission roller devices for photovoltaic glass toughening, including high-pressure wind grid roller way, high-pressure wind grid roller way is installed in high-pressure wind grid;With conveying direction as by front to back, high-pressure wind grid roller way is divided into the heat-resistant roller way area of front part and the conventional roller way area of rear part, heat-resistant roller way area is made of several high heat resistance rollers, high heat resistance roller is winding asbestos rope roller, conventional roller way area is made of several winding aramid rope roller. Through the application of the utility model, when photovoltaic glass is heated by electric heating furnace and enters high-pressure wind grid, first contact the winding asbestos rope roller of heat-resistant roller way area, it is full winding asbestos rope, with more durable heat resistance, can greatly improve the overall average life of high-pressure wind grid roller way. And the installation quantity of winding asbestos rope roller is controlled to not more than three, that is, the life of high-pressure wind grid roller way can be effectively improved, and the asbestos dust evaporation amount of asbestos rope can be guaranteed.

The invention relates to the technical field of racket sports goods, and discloses a sounding racket, comprising: a racket body including a racket body and a handle portion; a sound production assembly is arranged on the racket body, and the sound production assembly can produce prompt sound when the force of the racket swinging action reaches the preset force to prompt a user of the racket swinging force. According to the sounding racket, the sounding assembly is arranged, when the racket swings, air flow is generated to penetrate through the sounding assembly, the sounding assembly generates sound, good ball hitting feedback is provided for an athlete, the athlete can hit the ball more pleasantly, the sounding racket has certain characteristics, and the sounding racket is more interesting. When an athlete makes a sound by using the racket, the brand of the racket can be judged according to the sound, and brand propaganda is also facilitated. And the volume of the sound is determined by the racket swinging force, so that when a user or a trainee uses the racket, the racket swinging force can be controlled according to the volume of the sound, and the force control is realized.
