[0022] In this embodiment, the support plate 1 serves as the basic supporting structure of the entire device, and stably supports key components such as the stirring rod 2, the adjusting cylinder 3, the hopper 4 and the driving assembly. The stirring rod 2 is driven by the driving assembly to realize the rotation and stirring function, so that the emulsion raw materials are fully mixed in the container to promote the polymerization reaction. A discharge channel is provided in the stirring rod 2 to facilitate the discharge of the emulsion, thereby improving the uniformity of the emulsion mixing and the efficiency of the polymerization reaction. The hopper 4 ensures a stable supply of emulsion raw materials, reduces production delays caused by insufficient or interrupted raw materials, and improves production continuity.

[0024] In this embodiment, the introduction of the motor 8 realizes the automatic rotation of the stirring rod 2, reduces the dependence on manual operation, and improves production efficiency. At the same time, the stable output of the motor 8 ensures the continuity and uniformity of the rotation of the stirring rod 2, which is conducive to the full mixing of the emulsion raw materials and the smooth progress of the polymerization reaction. The meshing transmission mode of the bevel gear 9 has the advantages of high transmission efficiency, compact structure, and stable transmission ratio. It can effectively transmit the rotational power of the motor 8 to the stirring rod 2, while reducing the energy loss in the transmission process.

[0025] In a further preferred embodiment of the utility model, a plurality of electric telescopic rods 10 are installed at the bottom of the support plate 1, and the bottom of the plurality of electric telescopic rods 10 are all installed with the same base 11, a mixing barrel 12 is provided at the top of the base 11, and a plurality of universal wheels 13 are installed at the bottom of the mixing barrel 12, and a self-locking structure is provided on the plurality of universal wheels 13, and the plurality of universal wheels 13 are all in contact with the top of the base 11, and the stirring rod 2 can extend into the mixing barrel 12.

[0026] In this embodiment, the electric telescopic rod 10 can be telescopically adjusted as needed, thereby changing the relative height between the support plate 1 and the base 11, so that the operator can adjust the position of the mixing barrel 12 according to actual needs. The mixing barrel 12 is the main working space for emulsion polymerization. The design of the mixing barrel 12 should ensure that the emulsion raw materials can be fully mixed. The universal wheel 13 enables the entire equipment to be easily moved in the working area, which improves the flexibility and convenience of the equipment, so that the operator can easily move the equipment to the designated position as needed, which is convenient for replacing a new mixing barrel 12 for polymerization production.

[0027] In a further preferred embodiment of the present invention, a limiting block 15 is installed on the inner wall of the bottom of the mixing cylinder 12 , and a limiting cylinder 14 is rotatably installed on the bottom of the stirring rod 2 , and the limiting cylinder 14 can be movably sleeved outside the limiting block 15 .

[0028] In this embodiment, the limit block 15 serves as a positioning reference for the stirring rod 2 when it rotates in the mixing barrel 12, limits the lateral movement range of the stirring rod 2, prevents the stirring rod 2 from hitting the inner wall of the mixing barrel 12 due to the centrifugal force when rotating at high speed, reduces equipment wear and noise generation, and at the same time, the design of the limit block 15 also improves the positioning accuracy of the stirring rod 2 in the mixing barrel 12, ensuring the uniformity and consistency of the stirring effect, the use of the limit barrel 14 and the limit block 15 not only enhances the stability of the stirring rod 2 during the rotation process, but also reduces the decrease in stirring effect caused by vibration or deviation, and at the same time, this design also simplifies the structure of the equipment and reduces manufacturing and maintenance costs.

[0030] In this embodiment, the rotating shaft 16 serves as the rotation fulcrum of the limit plate 17, allowing the limit plate 17 to swing or rotate within a certain range. The limit plate 17 is connected to the electric telescopic rod 10 through the rotating shaft 16, and can swing or rotate to a certain extent when subjected to external force, and can adjust its angle when acting on the mixing barrel 12. The spring 18 provides a certain elastic support for the limit plate 17, so that the limit plate 17 can be elastically deformed and restored to its original state when subjected to external force. The design of the contact plate 19 makes the connection between the electric telescopic rod 10 and the mixing barrel 12 tighter and more stable. The contact between the contact plate 19 and the outer wall of the mixing barrel 12 also plays a certain positioning role, which helps to prevent the mixing barrel 12 from shifting or shaking during movement or use.

[0032] In this embodiment, the limiting telescopic rod 21 plays a guiding and limiting role inside the spring 18 to prevent the spring 18 from excessive deformation or displacement when subjected to external force. The design of the limiting telescopic rod 21 increases the rigidity and stability of the spring 18, so that the spring 18 can maintain a certain shape and position when subjected to external force, thereby ensuring stable contact between the resistance plate 19 and the outer wall of the mixing barrel 12. This design helps to prevent equipment loosening or failure caused by excessive deformation of the spring 18. The contact between the support plate 1 and the top of the mixing barrel 12 not only provides additional support for the mixing barrel 12, but also enhances the structural stability of the entire equipment, and at the same time can close the mixing barrel 12 to prevent material splashing.

[0033] In a further preferred embodiment of the utility model, the hopper 4 is provided with an observation window 6, the stirring rod 2 is provided with an electric valve 7 for controlling the feeding of raw materials, a handle is installed on one side of the mixing barrel 12, a discharge pipe is provided at the bottom of the mixing barrel 12, and a valve is installed on the discharge pipe.

[0034] In this embodiment, the observation window 6 allows the operator to directly observe the feeding of raw materials into the hopper 4. The electric valve 7 controls the feeding speed and amount of raw materials from the hopper 4 to the mixing barrel 12 according to a preset program or the operator's instructions, thereby improving the accuracy and stability of the emulsion polymerization process. The handle facilitates the operator to move, transport or adjust the position of the mixing barrel 12. The discharge pipe is used to discharge the evenly mixed emulsion from the mixing barrel 12, and the valve is used to control the opening and closing of the discharge pipe.

[0035] In summary, compared with the related art, the present device can fully polymerize the raw materials by setting a driving component to drive the stirring rod 2 to rotate. By setting a discharge channel in the stirring rod 2, the discharge of the emulsion is convenient, and the uniformity of the emulsion mixing and the efficiency of the polymerization reaction are improved.
