Cleaning tool of foaming machine, foaming machine and cleaning method of foaming machine

Abstract

The invention provides a cleaning tool of a foaming machine, the foaming machine and a cleaning method of the foaming machine. The cleaning tool comprises a self-cleaning outer pipe and a lifting mechanism, wherein the self-cleaning outer pipe is arranged on the outer side of a foaming gun barrel in a sleeving mode and at least partially accommodates the foaming gun barrel, and at least one air inlet hole is formed in the the self-cleaning outer pipe; the air inlet holes are used for communicating with the compressed air source through air inlet pipes; the self-cleaning outer pipe can be driven by the lifting mechanism to move upwards or downwards so that the foaming gun barrels can close or open the air inlet holes; and the compressed air source can exhaust air into the opened air inlet holes through the air inlet pipes so as to clean the inner walls of the self-cleaning outer pipe. By means of the cleaning tool, the automation degree of cleaning operation can be improved, the cleaning efficiency can be improved, the labor cost and the production cost are reduced, industrial alcohol for cleaning is prevented from hurting the bodies of workers, and potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of foam processing, in particular to a cleaning tool for a foam machine, a foam machine and a cleaning method for the foam machine. Background technique [0002] The high-pressure foaming gun head is the core component of the polyurethane foaming machine. The length of the barrel of the gun head on the market is generally short. In order to prevent it from interfering with the foaming mold during the foaming and pouring process, it is necessary to install a guide tube tooling on the barrel. [0003] In the prior art, after each foaming and pouring, the foaming material is easy to solidify on the inner wall of the guide tube tooling to cause blockage of the guide tube tooling. Rely entirely on manual work. [0004] However, the manual alcohol cleaning method has a low degree of automation and low cleaning efficiency, and the high labor cost has caused an increase in production costs, and the industrial alco...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, after each foaming and pouring, the foaming material is easy to solidify on the inner wall of the guide tube tooling to cause blockage of the guide tube tooling. completely dependent on manual work

[0004] However, the manual alcohol cleaning method has a low degree of automation and low cleaning efficiency, and the high labor cost has caused an increase in production costs, and the industrial alcohol used for cleaning is likely to cause physical harm to the staff and pose a safety hazard

If the speed of manual cleaning is not fast enough, the foaming material will easily solidify on the inner wall of the guide tube tooling and cause blockage

At the same time, the cleaned foam material is easy to splash and scatter to pollute the foaming room and the water tank shell after foaming processing. If it is not wiped in time, yellow spots will easily appear on the water tank shell and cause major after-sales quality problems. If it is wiped with industrial alcohol, It is easy to cause major after-sales quality problems such as cracking and scratching of the water tank shell

In addition, manual positioning is required during and after cleaning to adjust the foaming gun head to the same vertical height and align with the filling port. Manual positioning will increase the labor intensity of the staff. If the positioning is not accurate, it will also affect the follow-up operation. reliability
