Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator parts processing technology, specifically a spraying device for processing elevator parts. Background Technology
[0002] In modern industrial manufacturing, the spraying process is a crucial step in the production and processing of elevator components. Spraying not only gives elevator components an aesthetically pleasing appearance but also forms a protective film on their surface, providing corrosion resistance and wear resistance, thereby extending the service life of the elevator components and improving their performance stability.
[0003] However, traditional elevator component spraying equipment has revealed many limitations in practical use. For example, during spraying operations, the lack of an effective protective structure often results in paint splattering everywhere, making the working environment harsh and difficult to clean, increasing the labor intensity of workers, and potentially causing pollution and damage to surrounding equipment. Furthermore, most existing spraying equipment uses a single nozzle with a fixed spray angle, making it difficult to achieve simultaneous multi-angle spraying. This affects spraying efficiency and quality to some extent, and for elevator components with complex shapes and diverse sizes, it often cannot guarantee the uniformity and integrity of the spraying.
[0004] Traditional equipment also has some problems in the storage and transportation of coatings. The design of the storage structure is not reasonable enough, the feeding process is cumbersome and inconvenient, and the stability of transportation is difficult to guarantee for coatings of different viscosities, which can easily lead to blockages or unstable flow rates, thus affecting the continuity and effect of the spraying operation.
[0005] Furthermore, existing devices have poor adaptability in clamping and fixing workpieces. When dealing with elevator components of different sizes and shapes, frequent changes of fixtures or adjustments to the clamping device are often required, which is cumbersome, time-consuming, and labor-intensive, severely impacting production efficiency. Moreover, uneven or unstable clamping force during clamping can cause workpiece displacement, affecting coating accuracy and potentially damaging the workpiece surface.
[0006] Therefore, it is necessary to propose a spraying device for processing elevator parts. Utility Model Content

[0008] This utility model provides the following technical solution: a spraying device for processing elevator parts, comprising a spraying box, an integrated spray head, a storage box, mounting blocks, and a tilting frame. The integrated spray head is disposed inside the spraying box, and several spray heads are fixedly connected to the bottom end of the integrated spray head.

Combined with the linear motion constraints of the slider and groove, it achieves precise control of the spraying path. The bottom receiving box and guide structure work together to effectively collect excess paint and prevent equipment contamination, forming a closed-loop operation system. Attached Figure Description
