A fiber mat finished product quality control system, comprising a mixer, an opener, a carding machine, a web laying machine, a needle loom, and a trimming machine arranged in sequence in the production area. The fiber mixture is formed in the mixer, and is characterized by: The opening machine includes a coarse opener and a fine opener, a cotton storage box is provided between the coarse opener and the fine opener, the discharge end of the fine opener is connected to the air pressure cotton box, and the discharge end of the air pressure cotton box is provided with a leveler; The system also includes a temperature and humidity control system, which regulates the temperature and humidity of the air by spraying water mist in part or all of the production area, introducing a cyclonic airflow and a vertical downward airflow into the air pressure cotton box, and spraying the water mist into the air pressure cotton box. The vertical downward airflow and the water mist are used to compact the fiber mixture in the air pressure cotton box. The leveling machine includes a leveling assembly, a rotating roller assembly is provided on the bracket of the leveling assembly, the rotating roller assembly includes a rotating roller that performs a rotating motion, a material shifting rod kit is provided on the rotating roller, and a material shifting rod is provided on the material shifting rod kit; The bracket is provided with a fixed splint and a movable splint, the rotating roller is provided with a shifting rod, and the movable splint is provided with a connecting rod. The shifting rod rotates with the rotating roller and causes the shifting rod to shift the connecting rod at intervals, so that the movable splint is close to or away from the fixed splint. The bracket is provided with a guide groove, the connecting rod is arranged in the guide groove, and the connecting rod on the movable splint reciprocates along the guide groove; When the material moving rod is close to the fiber mixture, the movable splint moves closer to the fixed splint, and when the material moving rod is away from the fiber mixture, the movable splint moves away from the fixed splint; A sleeve is provided on the periphery of the rotating roller assembly, and the sleeve includes a central tube and edge tubes arranged at the four corners of the central tube. A number of spaced through slots are provided at the central tube and the connection between the central tube and the edge tube. When the rotating roller rotates, the material-moving rod passes through the through slot, and an air inlet pipe and an air outlet pipe are provided on the fixed splint. When the fixed splint and the movable splint clamp the two ends of the fiber mixture, air is taken in by the air inlet pipe, and the air flow flows along the sleeve, the fixed splint and the movable splint to blow the excess fiber mixture to the air outlet pipe, so that the fiber mixture is mixed with the air flow and flows out along the air outlet pipe.

2. The fiber mat finished product quality control system according to claim 1, characterized in that: The front end of the mixer is provided with two separately arranged feeding lines, and the feeding lines include a hopper, a feeder and a weighing machine arranged in sequence, and the two feeding lines convey chemical fibers and glass fibers respectively.

3. The fiber mat finished product quality control system according to claim 1, characterized in that: A quantitative device is provided at the end of the cotton storage box, and the cotton storage box inputs a quantitative amount of fiber mixture into the fine opener.

4. The fiber mat finished product quality control system according to claim 1, characterized in that: A cyclonic airflow and a vertical downward airflow are respectively introduced into the pneumatic cotton box through the air supply system. When the fiber mixture enters the pneumatic cotton box, the air supply system provides a cyclonic airflow to the pneumatic cotton box, and the cyclonic airflow is located at the upper middle end of the pneumatic cotton box. While the air supply system provides the vertical downward airflow to the pneumatic cotton box, the temperature and humidity control system provides water mist to the pneumatic cotton box. After spraying, the water mist is located above the fiber mixture, and the water mist moves downward with the vertical downward airflow.

5. The fiber mat finished product quality control system according to claim 1, characterized in that: The carding machine combs the fiber mixture into a mixed fiber web, and the web laying machine lays the mixed fiber web on a base cloth made of glass fiber, and the mixed fiber web and the base cloth are arranged in multiple layers to form a grammage of 830-870g / m 2 of plain fiber felt.

6. The fiber mat finished product quality control system according to claim 1, characterized in that: A belt scale is provided between the pneumatic cotton box and the leveling machine.

7. The fiber mat finished product quality control system according to claim 1, characterized in that: The material diverter rod comprises a first material diverter rod and a second material diverter rod. The length of the first material diverter rod is longer than that of the second material diverter rod. The first material diverter rod and the second material diverter rod are arranged vertically.

8. The fiber mat finished product quality control system according to claim 1, characterized in that: The leveling assembly includes a transmission assembly, a scraper plate is provided on the transmission assembly, and a through slot is provided on the scraper plate. The transmission assembly drives the scraper plate to perform reciprocating motion, and the material-moving rod passes through the through slot on the scraper plate.
