Technical Field

[0001] The utility model relates to the field of induction smelting, in particular to a gas jet strip material conveying system of an induction smelting strip making machine. Background Art

[0002] Vacuum ribbon spinning machine (such as induction melting ribbon machine) is a machine that heats the sample in the crucible to a molten state by induction heating or resistance radiation heating under high vacuum or inert gas protection atmosphere, and then quickly solidifies it on the surface of a high-speed rotating copper wheel or molybdenum wheel by air pressure spray to form amorphous or microcrystalline ribbons. It is mainly used for scientific research and development and small-scale production. The common problems of the original vacuum ribbon spinning machine are: the ribbon often deviates from the original trajectory and cannot reach the discharge port due to its own gravity or air flow disturbance when it leaves the copper wheel. After falling, the ribbon is entangled with the ribbon of the copper wheel behind, resulting in the destruction of the ribbon and economic losses. Utility Model Content

DETAILED DESCRIPTION

[0013] like Figure 1 As shown, the utility model proposes an induction melting strip making machine gas jet strip conveying system, the system is provided with a vacuum chamber, a gas jet assembly, and a strip collection system, mainly including a vacuum chamber 1, a strip throwing roller 2, a gas jet port 3, a gas jet chamber 4, a return air hole 5, an air inlet pipe 6, an air return pipe 7, a fan 8, a valve body 9, an air inlet hole 10, a metal strip pipe 11, a discharge pipe 12, etc. The specific structure is as follows:

[0014] A belt-spinning roller 2 is installed in the vacuum chamber 1, and a metal strip 13 is formed on the belt-spinning roller 2 in the vacuum chamber 1. The formed metal strip 13 is wrapped around the belt-spinning roller 2 and extends along the rotation direction of the belt-spinning roller 2, and is placed on the metal strip pipe 11 under the action of inertia. The metal strip pipe 11 is welded to the vacuum chamber 1, and the center axis direction of the pipe opening of the metal strip pipe 11 is 30 to 60 degrees obliquely downward. The metal strip pipe 11 is connected to the discharge pipe 12 by bolts through a flange to form a belt-collecting system, and the gas jet assembly corresponds to the place where the metal strip 13 is separated from the belt-spinning roller 2 through the gas jet port 3.

[0015] The gas jet assembly includes a gas jet port 3, a gas jet cavity 4, an air inlet pipe 6, an air return pipe 7, a fan 8, and a valve body 9. The specific structure is as follows:

[0016] The gas jet cavity 4 is located in the vacuum cavity 1. A row of circular holes are opened on the upper right side of the gas jet cavity 4, each of which is provided with a gas jet outlet 3. The gas jet outlet 3 is located 30 to 60 degrees obliquely below one side of the belt-spinning roller 2. The gas jet outlet 3 is directed to the point where the metal strip 13 leaves the belt-spinning roller 2 and corresponds to the bottom of the metal strip 13.

[0017] An air inlet hole 10 is provided at the lower left portion of the vacuum chamber 1, and the air inlet hole 10 is connected to one end of an air inlet pipe 6 outside the vacuum chamber 1. A valve body 9 is connected to the air inlet pipe 6, and the valve body 9 controls the on and off of the airflow in the air inlet pipe 6. The other end of the air inlet pipe 6 is connected to a circular hole on the connecting pipe of the fan 8, and the fan 8 is connected to the gas jet cavity 4 through the air inlet pipe 6.

[0018] An air return hole 5 is provided at the bottom of the vacuum chamber 1, and the air return hole 5 is connected to one end of an air return pipe 7 outside the vacuum chamber 1, and the other end of the air return pipe 7 is connected to a circular hole on the fan 8. The vacuum chamber 1 is connected to the fan 8 through the air return pipe 7.

[0019] The fan 8 is located outside the vacuum chamber 1. The high-pressure airflow it forms flows into the gas jet chamber 4 from the air inlet pipe 6, forming an air duct in the gas jet chamber 4. The high-pressure airflow flows in from the air inlet pipe 6 and is ejected from the gas jet port 3, forming a lifting force on the metal strip 13. The gas in the vacuum chamber 1 flows back to the fan 8 through the return air pipe 7.

[0020] The working process of the utility model is as follows:

[0021] The formed metal strip 13 is wound around the strip-spinning roller 2 in the vacuum chamber 1 of the induction melting strip making machine and rotates in the direction of rotation of the strip-spinning roller 2, and extends out to catch the metal strip pipe 11. The metal strip 13 is pushed toward the discharge pipe 12, and the fan 8 outside the vacuum chamber 1 forms a high-pressure airflow that flows into the air inlet pipe 6 and is ejected from the gas jet port 3, providing a lifting force for the metal strip 13 that is wound and moves forward in the direction of rotation of the strip-spinning roller 2, ensuring that the metal strip 13 enters the discharge pipe 12 smoothly. The airflow returns to the fan 8 from the return pipe 7 to ensure that the air pressure in the vacuum chamber 1 is constant.

[0022] The implementation results show that the gas jet metal strip conveying system of the utility model lifts the metal strip through the high-pressure gas from the flat air outlet, thereby achieving precise conveying of the metal strip, preventing the metal strip from sticking to the roller, and improving production efficiency.
