The lower end of the wear-resistant block 17 is slidably fitted on the side wall of the cam 8. The lower ends of the two screens 3 on the side away from the rectangular hole 5 are fixedly connected with a rectangular block 9. The lower end of the rectangular block 9 is fixedly connected with a telescopic rod 10. A fixed cylinder 11 is slidably sleeved on the side wall of the telescopic rod 10.

[0027] How it works
[0028] When the raw material screening device for tempered glass production is used, the motor 7 is first started, and the cam 8 fixedly connected to the end of the rotating shaft is driven to rotate by the motor 7. The mounting block 6 slidingly fitted with the cam 8 is driven to move upward, and at the same time, the two sieves 3 fixedly connected to the upper end are pushed upward by the mounting block 6, and at the same time, the spring 13 in the fixed cylinder 11 is stretched by the two telescopic rods 10 fixedly connected to the side walls of the two sieves 3. As the cam 8 continues to rotate, the cam 8 will lose its thrust on the mounting block 6, and at this time, the two springs 13 will return to their initial positions. State, this reciprocating motion will drive the two screens 3 to shake up and down, at this time, the tempered glass raw material is passed into the interior of the screening box 1 through the feeding pipe 2 fixedly connected to the top surface of the screening box 1, and then the larger impurities in the raw material are screened out through the screen 3 that preferentially contacts the raw material, and discharged through one of the rectangular holes 5 opened on the side wall of the screening box 1, and then the raw material falls onto the screen 3 below for secondary screening. At the same time, because the two screens 3 are constantly shaking up and down, the tempered glass raw material is effectively screened in multiple stages, and the screening efficiency of the tempered glass raw material is effectively improved.
