Problems solved by technology

[0004] The prior art has the following technical problems: 1. When using the prior art to spray paint on the electric hoist box, part of the sprayed paint is scattered on the ground or other places, which not only causes waste of paint but is also difficult to clean; 2. In the actual working environment The sprayed coating often falls off. The main reason is that the prior art does not press and brush when spraying paint, resulting in weak paint adhesion.

Embodiment 1

[0030] Such as figure 1 , figure 2 with image 3 Shown, in order to achieve the above object, basic scheme of the present invention is as follows:

[0031] The spraying process of the outer wall of the electric hoist box is as follows:

[0032] Step 1. Grinding: use sandpaper to grind the outer wall of the electric hoist box to be sprayed;

[0033] Step 2. Cleaning: Clean the outer wall of the electric hoist box polished in step 1, and then dry it;

[0034] Step 3. Temperature setting: ensure that the ambient temperature for spraying is 15-30°C;

[0035] Step 4, prepare a spraying device: the spraying device includes a spraying station 1, a hydraulic cylinder 31, a fixed part 3 and a spraying cover 2 driven by the hydraulic cylinder; the spraying cover 2 is located under the fixed part 3, and the spraying station 1 is located at the spraying cover 2 Below; hydraulic cylinder 31 is fixed on the fixed part 3. The spraying table is equipped with a rotating part for rotatin...

Embodiment 2

[0049] The difference between this embodiment and embodiment 1 is:

[0050] In step five, step six and step seven, the hydraulic cylinder 31 drives the piston 22 to move upward after 1 minute after the paint is sprayed. The rotational speed of the motor is 500r / min.

Abstract

The invention relates to the technical field of machines or devices adopting a jetting method for coating the surface of an object or surfaces of other workpieces with liquid or other fluid, in particular to an electric hoist box body outer wall spraying process. The electric hoist box body outer wall spraying process includes the following steps of firstly, grinding, secondly, cleaning, thirdly,temperature setting, fourthly, preparing a spraying device, fifthly, priming paint spraying, sixthly, middle layer paint spraying, and seventhly, surface layer paint spraying. By means of the technical scheme, oil paint is prevented from being sprayed on the ground, and waste of the oil paint is reduced; and the adhesive force of the oil paint can also be enhanced.

Description

technical field [0001] The invention relates to the technical field of machines or equipment for coating liquid or other fluids on the surface of objects or other workpieces by means of spraying, in particular to the spraying process of the outer wall of an electric hoist box. Background technique [0002] Electric hoist is a kind of lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation, and convenient use. It is used in industrial and mining enterprises, storage terminals and other places. [0003] In modern industry and daily life, metal corrosion can be seen everywhere, and the electric hoist box is also prone to corrosion. In order to prevent the corrosion of the surface of the electric hoist box, it is generally painted on the surface. The conventional spraying operation is mostly the processing method of spraying the primer layer, the middle coat layer and the top co...
