[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-4 This utility model provides a raw material mixing device for sanitary napkin production, including a mixing tank 1 and a lid 2; the mixing tank 1 and the lid 2 are sealed together, and the lid 2 and the mixing tank 1 are sealed together, which can effectively prevent the raw material dust from overflowing during the mixing process, avoid workshop pollution and raw material loss. The surface of the lid 2 is provided with a stirring component, and the outside of the mixing tank 1 is provided with a dispersing component.

[0024] The dispersion component includes a fixed block 3 fixedly installed on the outside of the mixing tank 1. An air pump 301 is installed on one side of the fixed block 3. An air pipe 302 is provided at the air outlet of the air pump 301. The end of the air pipe 302 away from the air pump 301 passes through the outside of the mixing tank 1 and is provided with an air distribution ring 303. Air flow nozzles 304 are evenly distributed circumferentially on the inner side wall of the air distribution ring 303. The jet direction angle of the air flow nozzles 304 can be adjusted. The air pump 301 installed on the fixed block 3 generates a high-pressure airflow, which is delivered to the air distribution ring 303 inside the mixing tank 1 through the air pipe 302. The air distribution ring 303 adopts a ring structure, which can evenly distribute the airflow input from a single air pipe 302 to multiple circumferentially distributed air flow nozzles 304, ensuring that the airflow coverage covers the entire cross-section of the tank body. The air flow nozzles 304 can adjust the jet direction according to the characteristics of the raw materials. For the dense area of ​​raw materials in the circulation flow of the stirring shaft 202, a high-speed airflow is directionally sprayed to break the local aggregation of raw materials and increase the mixing degree of raw materials.

[0025] Furthermore, such as Figure 2 and Figure 4As shown, the stirring assembly includes a motor 201 mounted on the top of the lid 2. The output end of the motor 201 passes through the lid 2 and is equipped with a stirring shaft 202. The stirring shaft 202 extends to the bottom of the mixing tank 1. The stirring assembly also includes crushing blades 203 and dispersing blades 204. The crushing blades 203 are mounted on the upper surface of the stirring shaft 202 and have a serrated structure. The dispersing blades 204 are mounted on the lower surface of the stirring shaft 202 and have a spiral structure. After the motor 201 is started, its output end drives the stirring shaft 202 to rotate at high speed along the axis. The crushing blades 203 and dispersing blades 204 on the surface of the stirring shaft 202 perform functional divisions according to their installation positions, forming a... The axial stirring effect of crushing from above and tumbling from below can quickly tear apart the adhesive structure inside the water-absorbing resin clumps, breaking the tendency of raw material stratification, and allowing high-density raw materials and lightweight fibers to be initially mixed. The edges of the crushing blades 203 and the dispersing blades 204 are equipped with elastic wall-hanging strips, which are tightly attached to the inner wall of the mixing tank 1. During the stirring process, the wall-hanging strips rotate synchronously with the blades, which can scrape off the raw materials attached to the tank wall in real time. The elastic material avoids rigid wear on the tank wall and ensures that there are no residues on the tank wall, improving the utilization rate of raw materials while preventing residual raw materials from deteriorating and contaminating the next batch of materials.

[0026] Furthermore, such as Figure 1 and 2 As shown, the top of the bucket lid 2 is provided with a feed inlet 402, the bottom of the mixing bucket 1 is provided with a discharge port 4, the bottom of the discharge port 4 is provided with an electromagnetic control valve 401, and the bottom of the mixing bucket 1 is provided with a vibrator. After confirming that the raw materials are mixed evenly, the electromagnetic control valve 401 at the bottom of the discharge port 4 is controlled to achieve continuous and stable output of the raw materials. During the discharge process, the vibrator at the bottom of the mixing bucket 1 can prevent the raw materials from forming bridging blockages at the discharge port. On the other hand, it shakes off the residual raw materials at the bottom of the bucket and the dead corner of the stirring shaft 202, ensuring thorough discharge and minimizing the amount of residue. The top of the bucket lid 2 is provided with a water inlet pipe 5, the bottom of the water inlet pipe 5 extends through the bucket lid 2 into the interior of the mixing bucket 1, and the top of the water inlet pipe 5 is equipped with a flange 501. The water inlet pipe 5 can be connected to an external water source through the flange 501. The flange 501 ensures the connection is sealed and prevents the flushing water from leaking. Clean water flows directly into the mixing tank 1 through the inlet pipe 5 to complete the cleaning process. There are mounting blocks 101 distributed around the outer perimeter of the mixing tank 1. The bottom of the mounting blocks 101 is fixed to the support column 102. The mixing tank 1 forms a stable support through the mounting blocks 101 and the support column 102 distributed around the outer perimeter, ensuring that the device does not shift during high-speed stirring and vibration.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
