[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A sound insulation cotton cutting device includes a numerical control cutting tool 1. On one side of the numerical control cutting tool 1, there is an installation base 2. The upper end surface of the installation base 2 is fixedly connected with a base table 3. An installation hole 4 is opened inside the base table 3. A motor buffer seat 5 is arranged inside the installation hole 4. A servo motor 6 is installed on the top of the motor buffer seat 5. The end of the output shaft of the servo motor 6 is fixedly connected with a connecting shaft rod 7. One end of the connecting shaft rod 7 away from the output shaft of the servo motor 6 is fixedly connected with a driving gear 8. The outside of the driving gear 8 is meshed with a driving gear disc 12. The outside of the driving gear disc 12 is fixedly connected with a material tray 11 arranged in a ring shape. The top of the material tray 11 is fixedly connected with a positioning fixture 17 with a cross-section in an inverted U shape. The inner wall of the positioning fixture 17 is fixedly connected with a spring telescopic rod 13. One end of the spring telescopic rod 13 away from the inner wall of the positioning fixture 17 is fixedly connected with a clamping plate 14.

[0027] A connecting spring 16 is sleeved outside the spring telescopic rod 13. The two ends of the connecting spring 16 are respectively fixedly connected with the inner wall of the positioning fixture 17 and the clamping plate 14. This setting enables the connecting spring 16 to cooperate with the spring telescopic rod 13 for use; the positioning fixtures 17 are arranged in an equiangular array with the same center of the circle, and the spring telescopic rods 13 are evenly arranged. This setting enables multiple sound insulation cottons to be positioned by multiple positioning fixtures 17; an annular limiting groove 9 is formed inside the base 3, and a positioning block 10 is slidably connected to the inside of the limiting groove 9. The positioning block 10 is fixedly connected with the lower end surface of the material tray 11. This setting enables the material tray 11 to rotate stably; an elastic pad 15 is fixedly connected to the side of the clamping plate 14 away from the spring telescopic rod 13, and the elastic pads 15 are evenly arranged. This setting enables the elastic pads 15 to act on the sound insulation cotton flexibly and stably.

[0028] Working process: All electrical appliances in the present utility model are provided with an external power supply or an internal battery. When the sound insulation cotton cutting device is to be used to cut the sound insulation cotton, the sound insulation cotton to be cut is placed between a group of elastic pads 15. The sound insulation cotton acts on the elastic pads 15, the elastic pads 15 act on the clamping plate 14, the clamping plate 14 acts on the spring telescopic rod 13 and the connecting spring 16, and the spring telescopic rod 13 and the connecting spring 16 act on the positioning fixture 17. When the spring telescopic rod 13 and the connecting spring 16 are compressed, a reaction elastic force will be generated, so that the clamping plate 14 and the elastic pads 15 can cooperate with the spring telescopic rod 13 and the connecting spring 16 to position the sound insulation cotton flexibly and stably. Then, the servo motor 6 installed through the motor buffer seat 5 is started. The motor buffer seat 5 is installed inside the base 3 through the installation hole 4. The angle and speed of the output shaft rotation of the servo motor 6 can be set through the built-in coding system of the servo motor 6.

After the numerical control cutting tool 1 finishes cutting the sound insulation cotton, the output shaft of the servo motor 6 will continue to rotate according to the preset angle and speed. When the material tray 11 rotates, it will drive the positioning block 10 to move. The positioning block 10 moves relatively inside the limiting groove 9, and the positioning block 10 rotates relative to the base 3. The base 3 is installed through the mounting seat 2, so that the material tray 11 can rotate stably.
