Surface coating process for binder clip

Abstract

The invention discloses a binder clip surface coating process which is carried out by adopting an automatic rolling spraying machine and comprises the following steps: S1, carrying out surface pretreatment on a binder clip; s2, a charging stage; s3, a preheating stage; s4, a spraying stage; s5, a cooling stage; and S6, an unloading stage. According to the surface coating process for the long-tail ticket holder, the labor cost of a long-tail ticket holder coating line can be reduced, the coating process is simple, the occupied area is small, the equipment investment is low, the paint loss is small, the construction environment is safe, and the comprehensive cost is optimal; and the requirement of greatly reducing the cost of an enterprise can also be met.

Description

technical field [0001] The invention relates to the field of surface coating, in particular to a surface coating process for long-tailed ticket holders. Background technique [0002] At present, with the continuous economic development and increasingly stringent environmental protection requirements, all walks of life are facing various problems and challenges such as upgrading and transformation, ecological environmental protection, and rising labor costs. In the field of subdivision - the surface coating of long-tailed ticket holders (stationery holders), the above-mentioned problems are also faced. On the one hand, it is necessary to transform traditional oil-based coatings into low-VOC water-based environmentally friendly coatings, and on the other hand, the surface coating process of traditional long-tailed ticket holders There are disadvantages such as complex coating process, high energy consumption, large floor space, high labor cost, large paint loss, and poor const...

Problems solved by technology

In the field of subdivision - the surface coating of long-tailed ticket holders (stationery holders), the above-mentioned problems are also faced. On the one hand, it is necessary to transform traditional oil-based coatings into low-VOC water-based environmentally friendly coatings, and on the other hand, the surface coating process of traditional long-tailed ticket holders There are disadvantages such as complex coating process, high energy consumption, large floor space, high labor cost, large paint loss, and poor construction environment safety. It is urgent to promote the upgrading and transformation of the entire industry through the improvement of surface coating process; currently used Low-VOC water-based environmental protection coatings for the surface coating of long-tailed ticket clips have been initially formed in the market, gradually replacing traditional solvent-based coatings; however, the surface coating process of long-tailed ticket clips still uses more traditional electrostatic spraying and a small amount of electrophoretic coating methods, high labor costs, high equipment investment, large floor area, high paint loss, difficult maintenance, etc., lead to high industry costs, severely squeeze profits, and seriously hinder the industry from upgrading its industrial structure and high-quality development

[0003] In the past, the roller spray coating process was mainly used for particularly small hardware parts, such as screws, paper clips, buttons, etc., which were irregular and difficult to hang. Although the assembly process requires a lot of labor, due to the low proportion of labor costs in the past, the cost of assembly line electrostatic spraying and electrophoretic coating process can still be accepted by enterprises, especially the proportion of assembly line electrostatic spraying in the ticket holder coating industry is very high. And solvent-based coatings have been used all the time. Solvent-based coatings still have great safety hazards when used for roller spraying. Therefore, there are no other coating methods to replace them in the ticket holder coating industry, especially roller spraying.
