[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a high-precision automatic fiber metering device, including a base 1. A groove is formed on the top of the base 1, and a support seat 4 is slidably connected to the inner wall of the groove. A metering sensor 2 is installed on the inner bottom wall of the groove. This sensor, a key component for accurate metering, senses the weight of the support seat 4, the metering hopper 6 above it, and the fiber material, converting the weight signal into an electrical signal and transmitting it to the controller body 16, thereby obtaining accurate weight data of the fiber material. A hydraulic cylinder 3 is fixedly connected to the inner bottom wall of the groove. The controller body 16 is located on the front of the base 1, and is electrically connected to both the metering sensor 2 and the hydraulic cylinder 3. The top of the pressure cylinder 3 contacts the bottom of the bearing seat 4. A connecting rod 5 is fixedly connected to the top of the bearing seat 4. A metering hopper 6 is fixedly connected to the top of the connecting rod 5. The metering hopper 6 has an internal cavity. A motor 7 is fixedly connected to the inner wall of the cavity. A transmission rod is splined to the output end of the motor 7. A worm 8 is fixedly connected to one end of the transmission rod. A worm wheel 9 meshes with the surface of the worm 8. A rotating shaft 10 is fixedly passed through the center of the worm wheel 9. A stirring shaft 11 is fixedly connected to the surface of the rotating shaft 10. The stirring shaft 11 stirs the fiber material in the metering hopper 6 to prevent the fiber material from tangling, agglomerating, or locally accumulating, so that the fiber material is evenly distributed, thereby improving the accuracy of metering.

[0027] The top of the metering hopper 6 is provided with a feed hopper 12, which is rectangular in shape to facilitate the smooth pouring of fiber material into the metering hopper 6;

[0028] The metering hopper 6 has a door 13 on the front, and a fixing plate 14 is fixedly connected to the front of the door 13. A handle 15 is fixedly connected to one side of the fixing plate 14, and the operator can easily open the door 13 by holding the handle 15.

[0029] The surface of the handle 15 is fixedly fitted with an anti-slip sleeve made of rubber to prevent operational errors or injuries caused by slipping when opening or closing the cabinet door 13.

[0030] The bottom of the base 1 is fixedly connected to the support leg 17, and the bottom of the support leg 17 is fixedly connected to the anti-slip pad, which increases the friction between the device and the ground, prevents the device from sliding during use, and ensures the stability of the device.

[0031] The front of the metering hopper 6 is provided with an observation window 18, which is rectangular in shape. The observation window 18 allows the operator to observe the state of the fiber material inside the metering hopper 6 at any time without opening the door 13.

[0032] In this invention, the working steps of the device are as follows:

[0033] First step: When it is necessary to measure the fiber material, the fiber material enters the cavity of the metering hopper 6 through the feed hopper 12. At this time, the motor 7 is started. The output end of the motor 7 drives the transmission rod to rotate, and the transmission rod drives the worm 8 to rotate. The worm 8 meshes with the worm wheel 9 and transmits power to the worm wheel 9, so that the worm wheel 9 rotates around the rotating shaft 10, thereby driving the stirring shaft 11 fixed on the surface of the rotating shaft 10 to stir the fiber material in the metering hopper 6. The stirring action of the stirring shaft 11 effectively avoids the fiber material from tangling, agglomerating and local accumulation, so that the fiber material is evenly distributed in the metering hopper 6.

[0034] The second step: After the fiber material is evenly mixed, the hydraulic cylinder 3 starts working under the control of the controller body 16. The hydraulic cylinder 3 drives the support seat 4 to move down, and the support seat 4 drives the metering hopper 6 to move down through the connecting rod 5. When the hydraulic cylinder 3 separates from the support seat 4, the weight of the metering hopper 6 and the fiber material inside it acts on the metering sensor 2. The metering sensor 2 converts the weight signal into an electrical signal and transmits it to the controller body 16. The controller body 16 processes and calculates the signal to obtain the accurate weight of the fiber material, realizing the automatic metering process. The entire metering process does not require manual picking, weighing and recording of data one by one, which greatly improves the metering efficiency.
