Mercury gun with double exhaust stroke

Abstract

The invention relates to an energy-saving lamp manufacturing machine, in particular to a dual exhaust rod mercury gun. The prior single exhaust rod mercury gun has a poor vacuum result and can not meet production requirements. The dual exhaust rod mercury gun is provided with two butt glass rods and has a better vacuum result; the dual exhaust rod mercury gun comprises a gun body with an inner cavity; an exhaust pipe communicated with the inner cavity is arranged on one side of the gun body; a mercury dropping seat consists of a sealing cap, a sealing element, a seal ring, an upper pressure cap, a seat cover and a magnetic conductive inner core are arranged at the upper end of the inner cavity; a seal fitting connected with the lamp glass rods is arranged at the lower end of the inner cavity of the gun body; the seal fitting comprises a mercury receiving bucket, a gasket and a hold down part axially connected in series from up to down; an external thread is arranged at the bottom of the gun body and screwed with a lower pressure cap upward supporting the hold down part; through holes communicated with the inner cavity of the gun body pass through the gasket and the upper off axis position of the hold down part; an adjustment blockage is arranged in the through hole on the hold down part; and an axial exhaust through hole is formed on the adjustment blockage. The dual exhaust rod mercury gun has the advantages of good vacuum result, and helps accelerate production speed and raise production capacity.

Description

【Technical field】 [0001] The invention relates to an energy-saving lamp manufacturing machine, in particular to a double-exhaust-rod mercury gun used on a round row car. 【Background technique】 [0002] The circular row car is a common lighting fixture production equipment. The mercury gun installed on the circular row car is mainly responsible for the processing tasks of exhausting and mercury dripping. During processing, one of the two glass rods is first sealed with fire. Then use a mercury gun to butt another glass rod to vacuum first, then drip mercury, and finally fire to seal it. In order to prevent the inner diameter of the glass rod from being too large, the mercury will fall into the lamp tube, and the inner diameter of the exhaust glass rod with external amalgam on the lamp tube is usually smaller. . When the round platoon car is working, it rotates quickly and the glass rod is basically blocked after dripping mercury. The actual vacuuming time of the mercury gun ...

AI Technical Summary

Problems solved by technology

When the round platoon car is working, it rotates quickly and the glass rod is basically blocked after dripping mercury. The actual vacuuming time of the mercury gun is very short. All these lead to poor vacuuming effect of the single exhaust rod mercury gun, which affects the quality of the lamp tube Reduce the qualified rate of finished lamp tubes, and cannot meet the production needs of external amalgam energy-saving lamp tubes
