Description

Technical Field

[0002] In the industrial production of chemical industry, metallurgy, food, building materials, pharmaceuticals, etc., powder equipment and processing are indispensable. Mixing is an important link in powder equipment and processing. Due to the production process requirements, it is often necessary to mix more than two powder raw materials in order to obtain a solid powder mixture with various powder components mixed evenly.

[0003] Similarly, in the production of powder as the final product, as the production conditions fluctuate, the product quality sometimes fluctuates. In order to ensure the stability of product quality, it is sometimes necessary to mix products produced in different batches through a powder mixer.

[0004] However, in the powder mixer in the prior art, different materials need to be added into the mixer in batches when mixing powders. Currently, the structure used for feeding is mostly a feeding hopper, which has a slow feeding speed and is prone to powder agglomeration and blockage. Feeding is laborious and has low practicality.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding mechanism for a powder mixer comprises a conveying pipe and an upper hopper constructed on the top of the conveying pipe;

[0008] Two servo motors are symmetrically installed at the bottom end of one side of the conveying pipe, and two brackets 1 are symmetrically installed at the top of the conveying pipe, and two brackets 2 are symmetrically installed at the bottom of the conveying pipe;

[0009] A transmission shaft is installed in the bracket one and the bracket two located on the same side so as to rotate together, and a spiral blade is fixedly installed on the outer edge surface of the transmission shaft. The bottom end of the transmission shaft is connected to a reducer fixedly installed on the bottom of the bracket two, and the motor shaft of the servo motor extends to one end of the conveying pipe and is fixedly connected to the input shaft of the reducer.

[0010] Furthermore, a sealing cover is detachably mounted on the top of the upper hopper, and through holes are centrally provided on both sides of the top of the sealing cover.

[0011] Furthermore, a feeding pipe is fixedly installed in the through hole, and a flange is fixedly installed on the top end of the feeding pipe by welding.

[0012] Furthermore, the tops of both sides of the upper hopper are each constructed with an extension ear 1, and the bottoms of both sides of the sealing cover are each constructed with an extension ear 2.

[0013] Furthermore, two through holes are symmetrically provided at the top of the second extension ear, and fastening bolts threadedly connected to the first extension ear are movably arranged in the through holes.

[0014] Furthermore, a fixing plate is welded and fixedly installed on the bottom end of the conveying pipe, and circular grooves are provided at four corners of one side of the fixing plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] Thanks to the two servo motors installed on the conveying pipe and the two transmission shafts equipped with spiral blades, when the powder is added to the upper hopper, the two servo motors can be started to drive the two transmission shafts respectively connected to the two reducers to rotate, thereby driving the two transmission shafts equipped with spiral blades to rotate, so as to push the powder, thereby inputting it from the upper hopper into the conveying pipe and discharged into the mixer, greatly improving the feeding speed and avoiding the phenomenon of powder agglomeration and blockage. The feeding saves time and effort and is highly practical.

[0017] Thanks to the setting of the upper hopper and the sealing cover, by fixing the sealing cover on the top of the conveying pipe, the powder is input into the upper hopper through the two upper pipes, thereby preventing the powder from overflowing. It is easy to use and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
