Utility Model Content

[0005] The purpose of the utility model is to provide a raw material mixing device for CPP film production to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a raw material mixing device for CPP film production, comprising a stirring mechanism, wherein a discharge filtering mechanism is provided at the bottom of the stirring mechanism;

After the CPP film raw materials are added, the motor is started, and the motor drives the stirring rod to rotate inside the bottom frame so that the raw materials can be evenly mixed. When the stirring rod rotates, it drives the scraper to scrape off the residues on the inner walls of the bottom frame and the top frame. This stirring method ensures the uniform distribution and mixing of the raw materials in the stirring chamber, ensures that the residues on the inner walls of the bottom frame and the top frame are completely scraped off, further improves the mixing effect, and achieves the effect of preventing the CPP film raw materials from adhering to the inner wall of the bottom frame and improving the processing efficiency of the CPP film raw materials.

[0009] Preferably, fixing holes are provided on the front and rear sides above the bottom frame and the top frame.

[0010] Furthermore, fixing holes are provided on the front and rear sides above the bottom frame and the top frame for tightly connecting the bottom frame and the top frame together through bolts to form a closed stirring chamber. This connection method ensures the sealing and structural stability of the stirring chamber. When the stirring mechanism needs to be cleaned, the bottom frame and the top frame can be easily disassembled by loosening the bolts, and the inside of the stirring chamber can be conveniently cleaned to ensure the hygiene of the equipment and the quality of the product.

The filter pad can further remove fine impurities in the mixed materials to ensure the purity of the final product. The filtered CPP membrane raw materials flow out through the leakage holes at the bottom of the filter frame to complete the discharge of the CPP membrane raw materials. Since the filter frame is connected to the bottom of the discharge pipe by threads, it can be disassembled by rotating the filter frame. The filter frame is rotated until the filter frame is separated from the discharge pipe, and then the disassembled filter frame is cleaned, thereby achieving fine filtration of the CPP membrane raw materials to ensure the purity and quality of the final CPP membrane raw materials.

[0017] Preferably, the discharge pipe is fixedly connected to the bottom of the bottom frame.

The bottom frame and the top frame are fixed by bolts, which is convenient for cleaning the inside of the bottom frame in the future and the inside of the stirring chamber to ensure the hygiene of the equipment and the product quality. After the CPP film raw materials are added, the motor is started, and the motor drives the stirring rod to rotate inside the bottom frame, so that the raw materials can be evenly mixed. When the stirring rod rotates, the scraper is driven to scrape off the residues on the inner walls of the bottom frame and the top frame.

[0033] The stirring mechanism 1 includes a bottom frame 101, a top frame 102 is bolted to the top of the bottom frame 101, a feed frame 103 is fixedly connected to the top of the top frame 102, a filter screen 104 is fixedly connected to the bottom of the feed frame 103, a stirring rod 105 is rotatably connected inside the bottom frame 101, scrapers 106 are fixedly connected to the front and rear sides of the stirring rod 105, and a motor 107 is fixedly connected to the left side of the stirring rod 105.

[0036] Specifically, support blocks 108 are fixedly connected to the front and rear sides of the bottom of the bottom frame 101 .

[0037] Through the above technical scheme, in the production process of CPP film, multiple raw materials need to be mixed in a certain proportion. The staff first prepares these raw materials according to the formula and adds them one by one into the stirring mechanism 1 through the feeding frame 103. Due to the filter screen 104 fixed on the inner wall of the feeding frame 103, the raw materials will be initially filtered when added to remove large particles of impurities. Fixing holes are opened on the front and back sides above the bottom frame 101 and the top frame 102. The bottom frame 101 and the top frame 102 are fixed by bolts, which is convenient for cleaning the inside of the bottom frame 101 in the future, and convenient for cleaning the inside of the stirring chamber to ensure the hygiene of the equipment and product quality. The internal circuit connection of the motor 107 is the existing technology and will not be repeated here. After the CPP film raw materials are added, the motor 107 is started, and the motor 107 drives the stirring rod 105 to rotate inside the bottom frame 101, so that the raw materials can be evenly mixed. When the stirring rod 105 rotates, it drives the scraper 106 to scrape off the residues on the inner walls of the bottom frame 101 and the top frame 102. This stirring method ensures uniform distribution and mixing of the raw materials in the stirring chamber, ensures that the residues on the inner walls of the bottom frame 101 and the top frame 102 are completely scraped off, further improves the mixing effect, prevents the CPP film raw materials from sticking to the inner wall of the bottom frame 101, and improves the processing efficiency of the CPP film raw materials.

[0042] Through the above technical solution, when the CPP membrane raw materials are evenly mixed, the staff turns off the motor 107. The switch valve 202 and the filter pad 204 are existing technologies and will not be described in detail here. The switch valve 202 is opened, and the mixed raw materials flow out through the discharge pipe 201 and are filtered twice through the filter pad 204 inside the filter frame 203.
