Currently, common latex coating production equipment on the market suffers from the following technical problems:

[0029] The guide vane structure 200 includes a main guide vane 210 installed at a 45° angle inside the feed pipe 100. The upper end of the guide vane is fixed to the inner wall of the pipe by a fixing structure 220. The lower part of the main guide vane 210 is designed with an arc-shaped guide surface 230, the entire surface of which is covered with a polished surface layer 240 to reduce flow resistance. A reinforcing rib 250 is also provided on the back to enhance structural strength. The tangential feed inlet 300 is composed of a tangential pipe 310, which is connected to the side wall of the storage tank 1 through an angle adjustment joint 330, and the connection angle between the pipe and the tank wall can be adjusted within the range of 15-30°. A 45° beveled port 320 is provided at the connection point.

The core of the diffuser assembly 400 is a conical diffuser body 410, which is designed with an expansion angle of 15°. The main body is equipped with a spiral guide vane 420, and the outlet end is equipped with a perforated distribution plate 430. The conical diffuser body 410 is connected to the end of the feed pipe 100 via a quick-connect clamp 440, and a sealing ring 450 is provided at the connection to ensure a seal.

[0030] The innovation of this invention lies in its targeted structural improvements, which enhance the performance of the feeding system in latex coating production equipment. To address uneven feeding, the inclined main flow plate 210 in the guide plate structure 200, combined with the arc-shaped guide surface 230, alters the direction of the vertically falling material flow, causing it to diffuse tangentially. Meanwhile, the tangential feed inlet 300, through its adjustable angle design, creates a swirling flow within the tank. These two flow modes are combined via a three-way distributor 600 and a flow control valve 500, which helps reduce dead zones at the tank edges and bottom, improves material distribution uniformity, and reduces sedimentation.

[0031] To address the issue of insufficient shear force control, the diffuser assembly 400 employs a multi-stage control mechanism: the expansion design of the conical diffuser body 410 alters the material flow velocity, the internal spiral guide vanes 420 guide the material flow, and the terminal porous distribution plate 430 disperses the flow into multiple streams. This design helps control the shear strength of the material entering the tank, protecting the polymer material structure while improving the uniformity of packing dispersion.

[0032] To enhance system flexibility, the three-way distributor 600 enables switching between vertical and tangential feed modes, while the angle adjustment joint 330 of the tangential feed port 300 supports dynamic adjustment of the feed angle. Both work together to adapt to the flow field characteristics required for formulations of different viscosities. Meanwhile, the quick-release clamp 440 design of the diffuser assembly 400 simplifies the disassembly process, and the sealing gasket 340 ensures assembly sealing. These designs make the equipment more flexible and efficient in formulation switching and maintenance.

[0033] In summary, improvements have been made to address the problems of uneven feeding, insufficient shear force control, and poor system flexibility inherent in traditional latex coating production equipment. By combining the design of the guide plate structure 200 and the tangential feed inlet 300, the uniformity of material distribution within the storage tank 1 is significantly improved, effectively reducing the formation of "dead zones" and sedimentation areas, thus enhancing product quality consistency. The conical diffuser body 410 and the spiral guide vane 420 in the diffuser assembly 400 work synergistically to precisely control the shear force during the feeding process according to different material characteristics, avoiding damage to the structure of the coated latex polymer material while ensuring uniform dispersion and improving product dispersion. The three-way distributor 600, in conjunction with the flow control valve 500 and the angle adjustment joint 330 of the tangential feed inlet 300, allows operators to flexibly switch between vertical feeding mode, tangential feeding mode, or a combination of both, greatly enhancing the system's adaptability to different formulations and process requirements. In addition, the quick-release clamp 440 design allows the diffuser assembly 400 to be quickly disassembled, facilitating cleaning and maintenance, and solving the problem of difficult cleaning of traditional equipment.

[0034] Compared with traditional technologies, this invention improves material uniformity through a guide plate structure; achieves precise control of shear force through a diffuser assembly; and enables more feed adjustments through a dual-feed system.

[0035] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
