An automatic cleaning method and automatic cleaning system for a powder coating production line

Abstract

The invention discloses an automatic cleaning method and an automatic cleaning system for a powder coating production line. The cleaning steps include the following steps: A), when the equipment of the powder coating production line receives the demand for automatic cleaning, the automatic cleaning mode is turned on; B), through automatic The cleaning tool automatically cleans the equipment of the powder coating production line; C), the monitoring device monitors whether the above step B) is completed according to the preset monitoring conditions; D), if the above step C) monitors that the above step B) has been completed, automatically The cleaning work of the cleaning tool is finished; E), the automatic cleaning mode is closed, and the automatic cleaning is completed; the present invention not only eliminates the potential safety hazards of the powder coating production line in the manual cleaning process, saves manual cleaning time, but also has no damage to the powder coating production line equipment, ensuring The service life of the equipment is extended, and at the same time, due to the monitoring of the cleaning process, the quality of automatic cleaning is ensured.

Description

technical field [0001] The invention belongs to the field of powder paint manufacturing, and in particular relates to an automatic cleaning method for a powder paint production line, and also relates to the automatic cleaning system. Background technique [0002] In the production of powder coatings, several production lines are usually used to realize production, and because powder coatings are widely used, their varieties (mainly reflected in color and performance) are rich and diverse. On the premise of ensuring production efficiency, in order to meet the product requirements of different customers' powder varieties, powder coating manufacturers need to frequently switch the production of different varieties of powder coatings on the same production line. [0003] When switching powder coating products used to produce different varieties (generally reflected in different colors or different properties), it is usually necessary to clean the extruder, tablet press, mill, cy...

Problems solved by technology

[0004] However, the powder coating manufacturing industry has generally used manual tool cleaning methods to clean various production equipment on the powder coating production line, such as: manual cleaning with resin or non-resin (easily crushed rice, corn, sawdust, toilet paper, etc.) The extruder on the powder coating production line is cleaned by the cleaning method or the cleaning method of disassembling the screw and the screw barrel, and the tablet press, mill, cyclone separator, sieve There are many problems in this manual cleaning method: because manual cleaning is performed manually by personnel, there are potential safety hazards; manual cleaning requires personnel to operate the whole process manually, which will cause a waste of working hours; further When cleaning the extruder manually, the amount of resin depends on personal habits, which is not conducive to resource conservation; while the method of cleaning the extruder by disassembling the screw and screw barrel manually can clean the extruder thoroughly, but it takes a long time. While wasting labor, it also affects production efficiency, and frequent disassembly and cleaning will cause damage to the screw and screw cavity of the extruder. At the same time, this method of disassembly and cleaning also has potential safety hazards; while cleaning with manual water washing will not only cause damage to the powder coating The internal humidity of the production line equipment and pipelines is high, which affects the quality of powder coating products and is not conducive to energy saving. At the same time, it corrodes some equipment components, causing corresponding damage and affecting the service life of the equipment; cleaning by manual air blowing requires the equipment to be separated. Disassemble and then clean it with air blowing. The dust generated by the blowing cannot be effectively controlled, which not only affects the working environment of employees, but also poses safety risks such as dust explosions.
