[0029] Furthermore, screws 11 are fixedly installed at both ends of the driving plate 5, and both ends of the screw 11 are fixedly connected to the outer end of the partition plate 14 and the output end of the rotating motor 12, wherein a rotating shaft is provided at the connection between the screw 11 and the partition plate 14.

[0030] Furthermore, two clamping plates 6 are provided and arranged in parallel at the lower end of the groove, wherein sliding blocks 15 are fixedly installed on the upper ends of the two clamping plates 6, and the sliding blocks 15 are movably sleeved on the outer ends of the screw rods 11, and are threadedly matched, and rubber pads 16 are fixedly installed on the inner sides of the outer ends of the clamping plates 6, and the two rubber pads 16 are arranged opposite to each other.

[0031] Furthermore, a placement groove 17 is provided at the center of the upper end of the movable plate 7 , and the placement groove 17 is correspondingly arranged at the lower end of the driving plate 5 .

[0032] Furthermore, the sensing component includes a weighing base 18, a sensor element 19, a push rod 20 and a protective spring 21. The push rods 20 are arranged in four numbers and are respectively fixedly installed around the bottom end of the movable plate 7. The sensor element 19 is arranged at the lower end of the push rod 20, and the weighing base 18 is fixedly installed at the lower end of the sensor element 19. The lower end of the weighing base 18 is fixedly connected to the inner wall of the base 1, wherein the outer ends of the push rods 20 are respectively sleeved with protective springs 21, and the two ends of the protective springs 21 are respectively connected to the bottom end of the movable plate 7 and the upper end of the weighing base 18.

[0033] Working principle: When the silicon block needs to be weighed, firstly, the rotation of the rotating motor 12 is controlled to drive the screw 11 to rotate and drive the sliding block 15 to move. Since the two clamping plates 6 are arranged in parallel and are respectively connected to the lower ends of the sliding blocks 15, the two clamping plates 6 will move toward the center or outward at the same time. When the clamping plates 6 move inward, the space between them is reduced, thereby clamping the silicon block. The rubber pad 16 on the inner side of the outer end of the clamping plate 6 can ensure that the silicon block is clamped stably and without damage. After the silicon block is clamped, the driving motor 8 starts to work, driving the telescopic rod 9 to contract and drive the driving plate 5 connected to the fixed block 10 to move downward. Since the clamping plate 6 and the driving plate 5 are fixedly connected, the silicon block is also moved to the placement slot 17 above the movable plate 7. In the embodiment, when the silicon block is placed in the placement groove 17, the movable plate 7 and the push rod 20 thereunder are moved downward by the gravity of the silicon block. When the push rod 20 moves downward, the sensor element 19 at the lower end detects the change and converts the signal into an electrical signal, which is transmitted to the electronic display screen 3 to determine the weight of the silicon block. The function of the protection spring 21 is to help the push rod 20 and the movable plate 7 return to their initial positions after the silicon block is removed. After the weighing is completed, the rotating motor 12 works again to make the screw 11 rotate in the opposite direction. The reverse rotation of the screw 11 will move the clamping plate 6 outward, thereby releasing the silicon block. Subsequently, the driving motor 8 makes the telescopic rod 9 rise, and lowers the driving plate 5 and the clamping plate 6 to the initial position for the next weighing operation.
