Description

Technical Field

[0001] This utility model relates to the field of raw material mixing technology for FIBCs (Flexible Intermediate Bulk Containers), specifically a raw material mixing device for FIBC production. Background Technology

[0002] As a large packaging container, the choice of raw materials for the production of FIBCs (Flexible Intermediate Bulk Containers) is crucial to the quality and performance of the product. The main raw materials include polypropylene, polyethylene, polyester, and nylon.

[0003] Chinese patent disclosure CN215743205U discloses a closed mixing device for raw materials in FIBCs (Flexible Intermediate Bulk Containers). The device includes a mixing tank, with a feed pipe fixedly connected to the top. A stirring motor is fixedly connected to the side of the mixing tank. A drive wheel is fixedly connected to the top of the stirring motor via an output shaft. A track is externally connected to the drive wheel. A positioning block is fixedly connected to the top of the mixing tank. A driven wheel is movably fitted inside the positioning block. A stirring shaft is fixedly connected to the bottom of the driven wheel. A fixing block is fixedly connected to the outside of the stirring shaft. This invention provides more uniform mixing of raw materials in FIBCs, ensuring the production quality of FIBCs, increasing the discharge speed of the mixed raw materials, and preventing blockages during material discharge. It is worthy of promotion.

[0004] However, it still has the following drawbacks: the device uses a first and second stirring rod to stir the raw materials, but it cannot mix the materials vertically. Different raw materials have different densities, and during the stirring process, materials of different densities may separate into layers. Therefore, we propose a raw material stirring device for the production of bulk bags to solve this problem. Utility Model Content

By setting the protective shell, it is convenient to protect the first bevel gear and bevel gear ring on the right side.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This raw material mixing device for the production of bulk bags, by setting up a first motor, a first connecting rod, a scraper, a spiral conveyor plate, a feeding pipe, a receiving plate, and a filter screen, starts the first motor, causing the spiral conveyor plate to transport the bottom material to the top of the conveying pipe, which facilitates the mixing of the upper and lower layers of material and avoids the phenomenon of material stratification. The filter screen and the receiving plate are used to screen out large pieces of material. The first motor drives the scraper to rotate, preventing large pieces of material from clogging the filter screen. By setting up a second motor, a shell, a fixed block, a crushing block, a first bevel gear, a rotating shaft, and a second bevel gear, starting the second motor causes the crushing block to rotate, so that large pieces of material are crushed by impact with the crushing block and the fixed block.
