Embodiment 1

[0030] Such as figure 1 , figure 2 In the shown embodiment 1, a filament lamp stem horn cooling device includes a middle air pipe 1, a side air pipe 2, an air distributor 3 and a solenoid valve 4. The air distributor 3 is in the shape of a cuboid as a whole, and the air distributor 3 There is a middle air pipe 1 inside, and the middle air pipe 1 includes a vertical main pipe 1, the bottom of the main pipe 1 is connected to the solenoid valve 4 through a variable diameter joint, and the other end of the solenoid valve 4 is connected to the high-pressure air supply system. Wherein the high-pressure air supply system is a high-pressure fan, which is a prior art. The bottom of the main pipe 1 is horizontally connected to both sides with a second branch pipe 13, the top of the main pipe 1 is horizontally connected to both sides with a branch pipe 12, and the top of the branch pipe 12 is connected with a number of vertical middle air outlets 121 along the extension direction of th...

Embodiment 2

[0033] A kind of cooling device for the horn of the filament lamp stem, the structure of which is roughly the same as that of Embodiment 1, the difference is that the top of the air distributor 3 is provided with a groove, and the side pipe bracket 22 is rotated and arranged in the groove, which can be adjusted according to different shapes. The bell mouth adjusts the angle of the side pipe bracket 22 to ensure that the side air outlet 21 is perpendicular to the side of the bell mouth, and the distance between each side air outlet 21 and the side of the bell mouth is consistent, and the applicable product range is wider; several middle air outlets 121 are in the air distributor 3 The center of the top surface is evenly distributed in a circular range, and the circular area is larger than the projected area of ​​the bell mouth on the top surface of the air distributor. This structure ensures uniform cooling inside the bell mouth.

Abstract

The invention discloses a filament wick column horn cooling device, which comprises a middle air pipe and a side air pipe. The middle air pipe is provided with a middle air outlet aligned with the inner side of a wick column horn, the side air pipe is provided with a side air outlet aligned with the outer side of the wick column horn, and the middle air pipe and the side air pipe are communicatedwith an air supply system. The invention has the following beneficial effects that: (1) high-pressure air supply is simultaneously carried out on the inner and outer sides of the wick column horn mouth, tempered crystals are rapidly cooled, the hardness and strength of the horn mouth are ensured, the product is not easy to break and the rejection rate is low; (2) a plurality of air outlets are formed to uniformly supply air to the horn mouth, so that stress is not easily generated, and the horn mouth has good toughness; (3) an electromagnetic valve accurately controls air outlet related parameters, and stable quality is guaranteed; and (4) the structure is simple, the cooling efficiency is high and the cost is low.

Description

technical field [0001] The invention relates to the technical field of lamp manufacturing, in particular to a filament lamp stem horn cooling device. Background technique [0002] The filament stem is made of glass, and one end of the stem is in the shape of an everted trumpet, so that the seal can be assembled to ensure airtightness. The stem horn is made by the stem horn molding equipment, and the existing stem horn is easy to break because of the thinner horn mouth. If the rupture occurs early, the horn will be scrapped; when the blister is broken during sealing, the seal will be scrapped, which will directly affect the sealing and molding of the blister, and the overall defect rate is between 3% and 5%. Even after the product is completed, there is a hidden danger of rupture. This means affecting the overall quality and service life of the product. Therefore, the quality of the stem flare is very important. In the prior art, the bell mouth is usually cooled naturally,...
