Description

Technical Field

[0001] The utility model relates to the technical field of preparing composite powder of flux-cored welding wire, in particular to equipment for preparing composite powder of flux-cored welding wire. Background Art

[0002] Flux-cored welding wire composite powder is made by mixing powders of various materials to optimize the performance and quality of the flux-cored welding wire, thereby improving the stability and hardness of welding. During the preparation process of flux-cored welding wire composite powder, it is mixed using flux-cored welding wire composite powder preparation equipment.

[0003] Since there are various types of raw material powders for preparing flux-cored welding wire composite powder, directly adding the raw material powders into the preparation device one by one according to the proportion will cause the raw material powders to be layered and piled up together. When mixing, it is very easy to cause uneven mixing of the raw material powders, and reduce the mixing efficiency, which is not conducive to quickly mixing them together.

[0004] Therefore, we proposed a flux-cored welding wire composite powder preparation device to solve the above-mentioned problems. Utility Model Content

[0010] Preferably, the interior of the upper section of the rotating rod is a hollow structure, and a baffle column is fitted in the hollow section of the rotating rod. This design allows the baffle column to move smoothly inside the rotating rod, adjust the relative position between the baffle column and the lower port of the conveying pipe, and realize the feeding control of the powder.

[0011] Preferably, the hopper is distributed at equal angles with respect to the longitudinal center line of the rotating rod, and the bottom surface of the hopper is distributed in an inclined shape, and the bottom surface of the hopper is inclined toward the conveying pipe. This design allows the powder in the hopper to be concentrated at the conveying pipe and transported and delivered along the conveying pipe.

[0012] Preferably, the feeding pipe is located below the conveying pipe, and the discharge port of the feeding pipe is tilted downward. This design allows the powder to be fed into the preparation machine casing through the feeding pipe for mixing.

This design can use the nozzles to clean the preparation casing and blow the powder to the middle position of the preparation casing for further mixing. In addition, the setting of the gas collecting seat can prevent powder from accumulating in the upper position of the gas collecting seat.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The flux-cored welding wire composite powder preparation equipment can control the synchronous rotation of the hopper and the feeding pipe by the rotation of the rotating rod. The hoppers distributed at equal angles can store the flux-cored welding wire composite powder raw materials separately. When the control column moves up to release the blockage of the feeding pipe, the powder can enter the rotating rod synchronously and be discharged from the feeding pipe synchronously. The powder is swung by the centrifugal force of the rotation so that it can be mixed when it is discharged, avoiding layered accumulation after feeding, so that it can be mixed quickly and evenly.

[0016] (2) The flux-cored welding wire composite powder preparation equipment uses a hair dryer to transport air to a gas collecting seat and sprays it from a nozzle toward the inner wall of a preparation casing, so that the powder centrifugally thrown toward the inner wall of the preparation casing continues to blow toward the center of the preparation casing, allowing it to be mixed in multiple cycles. The airflow sprayed from the nozzle can be used to blow and clean the preparation casing to prevent the powder from adhering to the inside of the preparation casing.
