Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stone powder hoppers for plastic masterbatches, specifically a stone powder hopper for plastic masterbatches with a dust-proof structure. Background Technology
[0002] In the production process of plastic masterbatch, stone powder hopper is a key piece of equipment used to store and transport stone powder raw materials for plastic masterbatch. When using traditional stone powder hopper, a large amount of dust is easily generated during the stone powder feeding process. The dust diffusion not only causes environmental pollution in the workshop and affects the health of operators, but may also lead to raw material waste and equipment failure.
[0003] Traditional hoppers mostly adopt open or simple sealed feeding structures. When stone powder is fed from the hopper, a large amount of dust is easily generated due to the collision between particles, the impact of falling, and the airflow disturbance inside the hopper. This dust lacks an effective collection path and will directly diffuse into the workshop air, causing the dust concentration in the working environment to far exceed the specified dust exposure limit. Long-term exposure will cause serious damage to the respiratory system of operators, so improvements are needed. Utility Model Content

[0021] Example 2 Please see Figure 1-4Furthermore, based on Embodiment 1, the auxiliary mechanism 5 includes a protective frame 51, which is fixedly connected to the right side of the hopper 3. A drive motor 52 is fixedly connected to the bottom of the protective frame 51, a linkage rod 59 is fixedly connected to the top of the drive motor 52, a gear 58 is fixedly connected to the top of the linkage rod 59, a gear ring 57 meshes with the left side of the gear 58, a separation disc 56 is fixedly connected to the inner side of the gear ring 57, a rotating motor 55 is fixedly connected to the left side of the storage box 2, a rotating rod 54 is fixedly connected to the right side of the rotating motor 55, the rotating rod 54 is rotatably connected to the inner side of the storage box 2, and a stirring plate 53 is fixedly connected to the outer periphery of the rotating rod 54.
