Description

Technical Field

[0001] The utility model relates to the technical field of powder material feeding adjustment, and more particularly to a powder material feeding adjustment device. Background Art

[0002] In existing technologies, powder feed adjustment devices are commonly used in industrial production, primarily for precisely controlling the discharge volume and speed of powder. However, existing powder feed adjustment devices suffer from a significant shortcoming during the discharge process: they are unable to effectively adjust the degree of powder compaction. This issue directly impacts the device's effectiveness and industrial production efficiency.

[0003] First, because existing powder feeding control devices lack a compaction adjustment function, the powder's compaction level often fails to reach the ideal state during the discharge process. This unstable compaction level can lead to problems such as stratification and agglomeration during transportation, storage, or subsequent processing, thus affecting product quality and production efficiency. Furthermore, this unstable compaction level can cause fluctuations in discharge volume, making it difficult to precisely control the material ratio during production, which in turn affects the quality and performance of the final product.

[0004] Secondly, existing powder feed adjustment devices fail to effectively adjust the compaction level during the discharge process, potentially leading to increased energy consumption and wear on the equipment. Due to unstable compaction levels, the equipment may require more energy to overcome friction between the powders during discharge, increasing energy consumption. Furthermore, unstable compaction levels can lead to increased wear on the equipment's internal components, shortening its service life and increasing maintenance costs. Utility Model Content

[0018] Beneficial effects:

[0019] 1. The discharge mechanism realizes precise adjustment of the compaction degree of powder through the design of transmission mechanism, feed sleeve, discharge sleeve, transmission shaft, variable pitch blade, block, fixed sleeve, push rod and clamping mechanism. The transmission mechanism drives the variable pitch blade to rotate in different discharge sleeves. Since the pitch of the variable pitch blade is different at different positions, powder with low powder density can be output at the front end, and powder with high compaction degree can be output at the rear end. This design enables the discharge process of powder to be adjusted according to production needs, thereby improving the flexibility and accuracy of powder feeding.

The follower plate drives the push rod to move, and then pushes the block to slide. The one-way plate is clamped in the annular groove, and the directional thrust is applied by the spring to ensure the stability of the clamping. This design enables the block to firmly seal the slide groove to prevent the leakage of powder during the discharge process and ensure the stability of the powder compaction degree. When it needs to be unlocked, the support sleeve contacts the one-way plate to unlock the connection between the one-way plate and the annular groove, so that the unlocking process can be realized conveniently and quickly.

[0021] 3. The transmission mechanism includes a reducer and a motor. The reducer is installed on the support frame, the motor is connected to the reducer, and the drive shaft is connected to the reducer. This design enables the motor and reducer to effectively drive the rotation of the drive shaft and the variable pitch blade, providing stable power output. The beneficial effect of the transmission mechanism is that it can adjust the speed of the variable pitch blade according to production needs, thereby controlling the discharge speed and compaction degree of the powder, and improving the degree of automation and operational convenience of the powder feeding adjustment device.

[0032] In this embodiment, when the powder needs to be put into the feed hopper 22, the variable pitch blade 5 is driven to rotate by the motor 21 and the reducer 20.
