A double-plug automatic feeding and gluing machine for producing LED lamp tubes

Abstract

The invention relates to the technical field of lamp tube production, and discloses a double-plug automatic feeding and gluing machine for producing LED lamp tubes. A power supply box is fixedly installed in the middle part of the top of the fixed tripod, and a chassis bearing is fixedly installed in the top of the power supply box. The invention uses the feeding turntable so that the plug parts can automatically move forward along the threaded curved track of the feeding turntable, thereby realizing the automatic feeding of the plug parts, adopting automatic grabbing of the plug parts, reducing the cycle interval time of gluing, effectively reducing the The cooling and solidification of the sprayed colloid, heat is generated by the heating belt, and the residual colloid can be re-melted, and then the spraying force of the nozzle is used to pull the residual colloid to fly out, avoiding the blockage caused by the solidification and accumulation of the residual colloid, and preventing the mixing and solidification of the sprayed colloid Colloidal impurities, in addition, a fixed sleeve is also used to avoid the position of the partial plug due to the rotational force generated by high-speed rotation.

Description

technical field [0001] The invention relates to the technical field of lamp tube production, in particular to a double-plug automatic feeding and gluing machine for producing LED lamp tubes. Background technique [0002] With the continuous update and development of lamps, LED light tubes are widely used in various fields. In the production process of LED light tubes, the plugging and gluing of LED light tubes is an important process. For the gluing of LED light tube plugs Generally, a glue machine is used for automatic glue work. Its working principle is to inject compressed air into the glue bottle and press the glue into the feed pipe connected to the piston chamber. When the compressed air pushes the piston to the upstroke, the piston chamber is filled with Colloid, when the compressed air pushes the piston in the downstroke, the colloid is pressed out from the needle nozzle, thus realizing the glue-making process. [0003] Although the existing gluing machine has the e...

Problems solved by technology

[0003] Although the existing gluing machine has the excellent characteristics of high speed and fast gluing, the glue required for the plugging of LED lamp tubes needs to be waterproof, sealable and easy to dry, so the plugging is performed in the gluing machine When gluing, there are sprayed colloid residues on the edge of the nozzle. After repeated gluing, the colloid residues will gradually increase, the colloids will cool and accumulate, and solidified colloids will be formed on the edge of the nozzle, which will hinder the ejection of new colloids. When it comes out, the eruption force will wash away the coagulated colloid on the inner side, and the coagulated colloid will be mixed in the new colloid to form impurities, thereby reducing the sealability of the glue, and there is a problem of poor waterproof sealing. In addition, the auxiliary glue machine to work The fixing mechanism of the plug part generally adopts the fixing method of direct inserting the sleeve. Due to the simple structure, when the glue is applied and rotated, the plug is not fixed stably. Work problems, for this we proposed a double plug automatic feeding and gluing machine for the production of LED lamp tubes
