[0003] Therefore, an automatic powder filling machine is needed to prevent blockage, so as to realize efficient powder filling operation on the heat pipe. CONTENT OF THE UTILITY MODEL

[0005] In a preferred embodiment of the utility model, a limiting frame is arranged in the inner cavity of the powder filling bin, and a filter screen for screening and filtering the powder is movably arranged on the limiting frame.

[0006] In a preferred embodiment of the utility model, the filter screen and the limiting frame are detachably connected.

[0011] In a preferred embodiment of the present application, a motor is installed on the mounting plate, and the output shaft of the motor is connected with a cam, and the cam is intermittently pressed with a contact plate installed on the outer wall of the powder filling bin.

[0012] Compared with the prior art, the present application has the following advantages: 1. The micro air compressor injects compressed air into the discharge pipe to form a slight positive pressure environment, helping the powder to overcome gravity and maintain smooth movement. This airflow assistance mechanism ensures that the powder can pass smoothly even in a small discharge pipe, greatly reducing the probability of blockage.

[0013] 2. The heater installed on the outer wall transmits heat to the airflow pipe through the heat pipe, maintaining a suitable working temperature to prevent the powder from caking due to moisture or low temperature.
