Automatic glue spraying device of PTC heating tube glue spraying machine

Abstract

The invention relates to an automatic glue spraying device of a PTC heating tube glue spraying machine, and belongs to devices special for manufacturing PTC heaters. The PTC heating tube glue spraying machine comprises a rack provided with a table board plate on the upper portion, a power mechanism arranged accompanying with the rack, a PTC heating tube conveying mechanism arranged on the table board plate, a PTC heating tube lifting mechanism arranged at the left end of the table board plate, and a PTC heating tube turnover mechanism arranged at the front side or rear side of the left end of the table board plate. The automatic glue spraying device comprises a PTC heating tube front face glue spraying mechanism and a PTC heating tube back face glue spraying mechanism; the PTC heating tube front face glue spraying mechanism comprises a front stand column, a rear stand column, a guide rod front fixing base, a guide rod rear fixing bases, a wire protecting beam, sliding guide rods, PTC heating tube front face glue spraying nozzles, a transmission motor, a transition transmission shaft, a front transmission wheel, a rear transmission wheel and a transmission belt protective cover fixed to the left side of the guide rod front fixing base; the PTC heating tube back face glue spraying mechanism comprises a front stand column, a rear side stand column, a guide rod front fixing base, a guide rod rear fixing bases, a wire rail protecting beam, sliding guide rods, a PTC heating tube back face glue spraying nozzles, a front moving wheel and a rear moving wheel.

Description

technical field [0001] The invention belongs to the technical field of special devices for manufacturing PTC heaters, and specifically relates to an automatic glue spraying device of a PTC heating pipe glue spraying machine, which is used for spraying adhesive on the surface of the PTC heating pipe facing the heat dissipation aluminum sheet, so that the heat dissipation aluminum sheet It is fixed with the PTC heating tube by means of adhesive. Background technique [0002] The aforementioned PTC heating tube is a part of the structural system of the PTC heater (also called "PTC heater" in the industry, the same below). Specifically, the PTC heater is mainly composed of the following four parts: one is the heating body, the The heating body is also called the radiator; the second is the PTC heating core; the third is the tailstock; the fourth is the electrical connection support seat. The heating body includes a PTC heating tube and a corrugated heat dissipation aluminum she...

AI Technical Summary

Problems solved by technology

The invention patent scheme can objectively fulfill the technical effect recorded in paragraph 0007 of its specification, but it has no inspiration for the gluing of the PTC heating tube, because the electrode strip is solid and can withstand the corresponding pressure, while the PTC heating tube The wall thickness of the PTC heating tube is usually below 2 mm, or even below 1.5 mm (see paragraph 0019 of the aforementioned CN201499328U specification), and because the lumen of the PTC heating tube needs to be provided with the aforementioned PTC heating core, it is hollow, so if If it is glued by roller coating, that is, by contact, it will inevitably cause deformation

Especially as mentioned above, because the two sides of the PTC heat pipe form slots for the insertion of heat dissipation aluminum sheets, the glue roller cannot transfer the adhesive to the slots

[0007] It can be seen from the above description that the above technical problems can only be solved by spraying the adhesive to the PTC heating tube with a glue spraying device with a reasonable structure and in a non-contact state with the PTC heating tube. However, in the patents and non-patent documents disclosed so far There is no corresponding technical inspiration
