Description

TECHNICAL FIELD

[0001] The utility model relates to conveying equipment field, especially a material conveying mechanism for powder spraying workshop. BACKGROUND

[0002] The powder spraying workshop is mainly used for coating treatment on the surface of metal or nonmetal material to improve the corrosion resistance, wear resistance and aesthetic degree of the material surface. The suspended chain conveyor plays a vital role in the powder spraying workshop. The suspended chain conveyor drives the carrier or material to realize continuous conveying in the three-dimensional space through the suspended chain. In the powder spraying workshop, the suspended chain conveyor can efficiently convey the workpiece from one production line to another production line or send it into the drying chamber for drying. When the suspended chain conveyor is used to convey the workpiece in the powder spraying workshop, the workpiece is often directly suspended on the hook of the suspended chain conveyor. However, with the work of the suspended chain conveyor, the workpiece suspended on the hook will be greatly shaken due to the influence of inertial force and other factors. In the powder spraying workshop, the workpiece suspended on the suspended chain conveyor will be greatly shaken, which will directly affect the powder spraying effect and coating quality. The large shaking may cause uneven coating on the surface of the workpiece, resulting in missed spraying or re-spraying, which reduces the aesthetic degree and protective performance of the product. At the same time, the large shaking may also change the distance between the workpieces, affecting the spraying range and efficiency of the spray gun. In addition, the large shaking may also increase the wear and energy consumption of the equipment, which adversely affects the production efficiency and cost control. Therefore, a material conveying mechanism for powder spraying workshop is needed to avoid the above problems. SUMMARY

When conveying the workpiece through the hook conveying chain 4, the workpiece can be hung on the hooks on the hook conveying chain 4, and in order to avoid the workpiece from being greatly shaken by factors such as inertial force during the conveying process of the hook conveying chain 4, the workpiece can be pulled down and fixed by the pull hook assembly 3 cooperating with the hook conveying chain 4, the method is that, first, the adjusting rod 12 and the threaded rod 9 are relatively rotated to adjust the length of the entire pull hook assembly 3, then the tension hook 15 is pulled up to make the tension hook 15 hang on the workpiece, and when the tension hook 15 is pulled up, the spring pressing plate 10 will compress the tension spring 11, when the tension hook 15 hangs on the workpiece, the tension hook 15 can be loosened, at this time, under the elastic force of the tension spring 11, the tension hook 15 will be pulled down, and finally under the elastic force of the tension spring 11, the workpiece will be pulled and fixed by the tension hook 15 and the hook conveying chain 4; then, when the hook conveying chain 4 moves with the workpiece, the workpiece will slide the pull hook assembly 3 on the guide rail 2,

[0021] Finally, by setting the guide rail 2 below the hook conveying chain 4, the pull hook assembly 3 is slidably arranged on the guide rail 2, the pull hook assembly 3 can tension and fix the workpiece suspended on the hook of the hook conveying chain 4, thereby reducing the probability of the workpiece suspended on the hook of the hook conveying chain 4 being greatly shaken by the influence of inertial force and other factors, and further ensuring the powder spraying effect and coating quality of the workpiece, while also reducing the wear and energy consumption of the conveying mechanism.
