A method for automatic glazing of pipelines

Abstract

The invention discloses an automatic glazing method for a pipeline. The automatic glazing method comprises the following steps: A, positioning a pipeline carrier on a workbench of a glazing machine via a positioning device, wherein the lower end port of a pipeline is allowed to be aligned with the glazing port of the glazing machine; B, driving overturning of the workbench via an overturning drive unit and allowing the pipeline carrier to overturn together with the workbench and the glazing machine to carry out glazing on the pipeline; C, detecting whether glaze reaches the upper end port of the pipeline via a liquid level detection device and controlling the glaze supplying device to stop supply of the glaze when the glaze reaches the upper end port of the pipeline; and D, extracting out the glaze in the pipeline via a glaze extracting device and allowing the overturning drive unit to drive the workbench to overturn to an initial position. The glazing method provided by the invention drives overturning of the workbench via the overturning drive unit so as to facilitate thorough entering of the glaze into the bent part of the pipeline and guarantee full glazing of the inner wall of the pipeline; and the glazing method monitors whether pipeline glazing is adequate in real time via the liquid level detection device, so overflowing of the glaze can be prevented while adequate pipeline glazing is guaranteed.

Description

technical field [0001] The invention relates to the field of glazing, in particular to an automatic glazing method for pipelines. Background technique [0002] In order to improve the smoothness of sewage discharge of the toilet sewage pipe, a layer of glaze is generally applied to the inner wall of the toilet sewage pipe, but the toilet sewage pipe is a curved pipe, so it is difficult to fully apply the glaze. The following two implementation methods are generally adopted in the prior art The toilet sewage pipe is glazed. [0003] In the first implementation mode, manual glazing is carried out directly from the pipe mouth. Since the pipe is in a curved shape, this method can only be applied to the end side wall of the pipe, and the curved part of the pipe is difficult to apply or can only be applied to some areas. , The part of the pipeline that has not been glazed has pores, which is prone to staining and even blockage. [0004] In the second embodiment, the glaze is fir...

Problems solved by technology

[0004] In the second embodiment, the glaze is first poured into the pipe, and then the remaining glaze is drawn out. Although this embodiment can basically satisfy the glazing on the inner wall of the pipe, it is difficult to control the amount of glaze. As a result, it overflows to the sewage inlet, and the extra glaze of the sewage inlet needs to be scraped off, which increases the workload. In order to solve this problem, the existing technology uses a plug to plug the sewage inlet, but it still cannot accurately control the amount of glaze
