Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] Such as Figure 1 to Figure 6As shown, a filament lamp sealing and removing device includes a tubular mandrel 4 and a mechanism for delivering high-pressure air. The mechanism for delivering high-pressure air is located at the bottom of the mandrel 4, and the top of the mandrel 4 is connected to the glass lamp housing 11. An inner tube 3 is arranged inside the mandrel 4, and there is a gap between the mandrel 4 and the inner tube 3 to form a first airflow channel 9. The end of the inner tube 3 adjacent to the top of the mandrel 4 is provided with a fire sealing core 1, and the fire sealing core 1 set on the inner tube 3, the top of the fire sealing core 1 is connected with the filament stem 12, the outer circumference of the fire sealing core 1 is provided with a fire sealing core head 2, the top of the fire sealing core 1 is above the fi...

Abstract

The invention discloses a filament lamp sealing and removing device and method, and provides a filament lamp sealing and removing device capable of blowing thin molten glass and breaking it without manual tearing, easy to operate and excellent in effect. feeding device. It includes a tubular mandrel and a mechanism for delivering high-pressure air. The mechanism for delivering high-pressure air is located at the bottom of the mandrel. The top of the mandrel is connected to the glass lamp housing. There is an inner tube inside the mandrel. The gap forms the first air flow channel. A fire sealing core is provided on the end of the inner tube adjacent to the top of the mandrel. The fire sealing core is sleeved on the inner tube. The top of the fire sealing core is connected with the filament core column. The fire plug, the top of the fire sealing core is above the top of the fire sealing core, and there is a gap between the fire sealing core and the top of the fire sealing core, forming a second air flow channel communicated with the first air flow channel. The invention can thin the side wall of the molten glass stem until it breaks by blowing air, so as to realize the effect of removing the tailings of the filament lamp.

Description

technical field [0001] The invention relates to the field of production and processing of lighting fixtures, in particular to a device and method for sealing and removing filament lamps. Background technique [0002] The lamp manufacturing method of the existing filament lamp is as follows: the glass lamp housing is placed on the supporting mold, and the filament stem is placed at the same time. Adjust the fire head to an appropriate size, heat and fire the handle. When the temperature at the stem reaches above 680 degrees Celsius, the glass begins to melt. Affected by the center of gravity, the glass begins to flow downward, making the melting point become thinner and thinner until it breaks, realizing the separation of the glass stem and the glass lamp housing. The glass lamp housing enters the shaping mold to be clamped, blown, shaped and then annealed to complete the sealing of the glass lamp housing, and the filament stem is fixed in the bulb. [0003] This traditiona...
