Inflatable protective device for sealing machine with energy-saving lamp tube

Abstract

The invention provides an inflatable protective device for a sealing machine with an energy-saving lamp tube, belonging to the technical field of sealing equipment in energy-saving lamp manufacturing industry. The inflatable protective device comprises a 'rightward U-shaped' main support, a proximity detection component, a signal receiving control unit and a protective gas container, and an interlocking mechanism, wherein the proximity detection component, the signal receiving control unit and the protective gas container are communicated with a data line signal, the signal receiving control unit and the protective gas container are respectively fixed at the middle and lower parts of an upright column of the 'rightward U-shaped' main support; a gas-guide tube of the protective gas container stretches into a core column shaft of the sealing machine to be connected with an exhaust tube of a core column; the top end of the 'rightward U-shaped' main support is equipped with a setting piece of the interlocking mechanism in a sliding manner; the proximity detection component is fixed at the bottom of the setting piece; and a left fire head support and a right fire head support of the interlocking mechanism are respectively fixed on a left fire head rod and a right fire head rod of the sealing machine. The inflatable protective device plays a role in protecting the head of the core column, avoids oxidation of filament and an indium mesh under high temperature, thus reducing early-stage black head problem of a part of the lamp tubes, stabilizing sealing quality and improving production efficiency.

Description

technical field [0001] The invention relates to an inflatable protective device for an energy-saving lamp tube sealing machine, which belongs to the technical field of sealing equipment in the energy-saving lamp manufacturing industry. Background technique [0002] In the manufacturing process of energy-saving lamp tubes, sealing at both ends is an important process in manufacturing. At present, the sealing of energy-saving lamps in my country is mainly completed by manual operation. The sealing steps are: use gas, oxygen, and high-pressure air to ignite two semicircular fire heads, hold a stem in the left hand and place it in the stem shaft, and pull the fire head with the left hand. Go in and out of the rotating disk to move the two semicircular burners to both sides of the stem shaft, pick up a lamp tube with your right hand, align one of its legs with the burner and heat it to soften it, then move the softened lamp leg to cover the stem , the flame directly heats and seal...

AI Technical Summary

Problems solved by technology

However, there is no doubt that there is a certain degree of difference due to the operator's work experience, labor proficiency and the state of the sealing machine flame.

Therefore, the quality of the lamp seal cannot be guaranteed at all

Moreover, under normal circumstances, in order to ensure the formation of the seal, the operator will prolong the burning time and annealing time of the sealing station, and increase the contact area between the sealing fire head and the horn, which often causes the local heating to be too high, resulting in blown horns and stems. , and it is easy to cause the filament and indium network of the stem to be oxidized by high temperature, and the early blackhead of the lamp tube and other problems
