Description

Ground rail type spraying line

Technical Field

The utility model relates to a ground rail formula spraying technical field, in particular to ground rail formula spraying line.

Background

The spraying generally comprises spraying paint and spraying powder, wherein the spraying powder refers to a coating process of adhering powder paint on a workpiece by using corona discharge, and after the spraying powder, a coating film is formed on the surface of the workpiece through steps of hot melting, curing and the like. Because the coating of the workpiece after powder spraying is thick, traces which cannot be achieved by paint spraying can be covered, and the coating is hard after the powder is solidified, so that the coating is not easy to scratch, the workpiece is high-grade, and the water and the atmosphere are not polluted, so the powder spraying is favored by the industry compared with the paint spraying.

The ground rail line adopted by the ground rail type spraying line is a common conveying line in the spraying industry, and the conveying chain is mainly adopted to convey workpieces. Compared with non-ground rail lines with publication numbers of CN214637530U and CN105935636B, the ground rail spraying line related to the application is different in that the lower part of a jig (driving a workpiece to rotate so as to realize 360-degree powder spraying of the workpiece) is not in a suspended state, and the lower end of the jig is clamped and fixed on a conveying chain.

Therefore, for the ground rail spraying line related to the application, because the raw material used for spraying powder is plastic powder, in the powder spraying process, the plastic powder is uniformly sprayed on the workpiece, and part of the plastic powder inevitably falls on the jig and the conveying chain, so that the powder entering into the bearing and the conveying chain of the jig is easily blocked. For this reason, the general practice in the industry is as follows:

1. after powder spraying, a workpiece is not rotated (wherein the workpiece is not rotated, namely, the workpiece is taken down from a clamp, the clamp is loaded on the top of a jig, and the workpiece is clamped on the clamp), the workpiece, the clamp, the jig and a ground track directly enter a baking oven to be heated, dried and solidified, therefore, when powder coating on the surface of the workpiece is heated and solidified, powder on the clamp, the jig, a jig bearing and a conveying chain is solidified in a joint manner, and the spraying operation of a new workpiece is repeated in such a reciprocating manner, the solidified powder is more and more thick, the jig bearing and the conveying chain serving as a transmission part are bound to have a serious powder clamping phenomenon, so that the jig bearing and the conveying chain are directly clamped, and the machine needs to be shut down to be overhauled, cleaned and maintained after the spraying operation is carried out for a period of time, the clamp also needs to be cleaned and descaled regularly, and the maintenance cost is higher.

2. After powder spraying, a workpiece is not rotated, and only a double-layer dustproof structure is arranged on a ground rail type spraying line to reduce the powder feeding amount, but the scheme is temporary and permanent, and the phenomena of powder feeding and powder blocking cannot be fundamentally solved;

3. after powder is sprayed, a workpiece is rotated, namely, the workpiece is taken down from the jig by using the manipulator and is placed in a baking oven for independent heating, drying and curing, at the moment, the jig and the conveying chain do not enter the baking oven, but in the process of rotating the workpiece, in order to avoid the direct contact of the manipulator with the surface of the workpiece, the manipulator clamps the workpiece indirectly (in the industry, a clamp is generally required to be arranged between the jig and the workpiece to clamp the workpiece, and the aim of avoiding the direct clamping of the workpiece surface by the manipulator when the workpiece is taken out) by avoiding the direct clamping of the workpiece surface by the manipulator when the workpiece is taken out, so that in the drying and curing process, the powder on the surface of the clamp is naturally heated, dried and cured together with the powder on the surface of the workpiece, the clamp needs to be cleaned frequently, if the clamp is not cleaned timely, a thick and abrupt and non-uniform adhesion layer is formed after multiple times of heating and curing, the clamping with the workpiece and the jig is seriously affected, and the clamping of the manipulator is unstable.

Therefore, how to develop a ground rail type spraying line which can avoid the powder clamping phenomenon of a jig bearing and a conveying chain and can also avoid the powder sticking phenomenon of a clamp is a technical problem to be solved urgently by technical personnel in the field.
