Water heater liner automatic enamel coating machine sealed fast glazing device

Abstract

The invention provides a sealed type fast glaze return device for an automatic water heater inner container enamelling machine. The sealed type fast glaze return device comprises a glaze collecting box used for collecting remaining glaze, a soft pipe, a rigid pipe and a connecting rod mechanism, wherein the soft pipe and the rigid pipe are sequentially connected with the glaze collecting box in series. The connecting rod mechanism comprises a first connecting rod and a second connecting rod. One end of the first connecting rod is connected with the lower end of a swing rack, and the other end of the first connecting rod is connected with one end of the second connecting rod through a rotating shaft device. The other end of the second connecting rod is movably connected with the rigid pipe. The fast glaze return device further comprises an upper glaze return groove. At least one first guide groove is formed in the upper glaze return groove. First guide wheel assemblies are arranged at the free end of the rigid pipe. First guide wheels of the first guide wheel assemblies are located in the first guide grooves, and connected with the free end of the rigid pipe through first guide wheel connecting parts. The inlet end of the rigid pipe is always higher than the free end. An inclination angle is formed between the inlet end of the rigid pipe and the upper glaze return groove, so that an outlet of the free end is always located within the inlet range of the upper glaze return groove in the back and forth moving process. The fast glaze return device has the advantages that the structure is simple, return glaze can be sealed, pipelines are not prone to being blocked, and the service life is long.

Description

technical field [0001] The invention relates to a sealed glaze return system of an automatic enameling machine for a water heater inner tank, in particular to a sealed fast glaze return device for an automatic enameling machine capable of rapid glaze return. Background technique [0002] The water heater liner coating machine generally includes a bracket, a swing frame and a swing drive mechanism set on the beam of the bracket. The swing frame is rotated counterclockwise by 105 degrees from the vertical state through the swing drive mechanism. When the object to be enamelled on the swing frame, For example, the inner tank of a water heater is injected with glaze at 105 degrees counterclockwise. When the swing frame turns to a vertical state, the remaining glaze in the enamelled object pours from the enamelled object outlet on the enamelling machine to the glaze on the ground. In the box, due to the special design of the enamelling machine for the inner tank of the water heat...

AI Technical Summary

Problems solved by technology

[0004] However, in the actual use of this sealed reglazing system, there are still too many folded pipes used for reflowing the remaining glaze, and there is too much glaze in the pipes during reglazing, so it cannot be quickly returned to the glaze receiving box; , due to the strong viscosity of the glaze, the glaze return pipe is easily blocked during the production process

Furthermore, the joints of the folded back-glazed pipes have a large range of motion, and there is a problem that the soft joints of the pipes are easily damaged.
