Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a material spraying device for building construction. Background Technology
[0002] Decorative materials are building materials and their products mainly used to decorate the interior and exterior walls of buildings, construct interior walls, and achieve some functional use on the basis of decoration. They are used to decorate various civil and wooden buildings to improve their functionality and aesthetics, and to protect the stability and durability of the main structure under various environmental factors.
[0003] In the prior art, Chinese Patent Publication No. CN221245702U discloses a spraying machine that facilitates the loading and unloading of processed parts. It includes a spraying machine assembly, a conveying assembly, and a clamping assembly. The spraying machine assembly is equipped with a conveying assembly, and both the spraying machine assembly and the conveying assembly are connected to the ground. The spraying machine assembly is equipped with a clamping assembly, which is installed and connected in the spraying machine assembly. The material is conveyed by the conveying assembly. After entering the working area of the spraying machine, the clamping assembly clamps the workpiece. Then, the clamped workpiece leaves the conveying assembly and is held by cylinders in two sets of clamping components. Then, the rotating motor controls the cylinders to rotate, which facilitates the spraying machine to spray the workpiece around.
[0004] However, in actual use, some paint residue remains on the conveying device during spraying, which is difficult to clean. Over time, the paint can easily clump and accumulate on the conveying device, affecting its flatness and thus the spraying of building products. Therefore, improvements are needed.

After each shift of material spraying, the fixing strip 9 is installed on the water tank 6. The bottom of the water tank 6 is lowered so that the baffle plate 10 can be installed to prevent water from splashing during cleaning. The lifting cleaning head 7 lowers so that the pressurizing nozzle 8 is close to the conveyor belt 3, thereby spraying out a water jet with impact force. The conveyor belt 3 is washed while it is moving. The mesh size on the conveyor belt 3 is moderate, and the slow transmission speed increases the washing time. The opening range of the wastewater flowing into the collection box 4 is large, so as to ensure that the water can be collected. After washing, the conveyor belt 3 is then dried to facilitate the subsequent spraying of workpieces and prevent material residue from affecting the spraying effect of the workpieces. The top of the fixing strip 9 is fixedly connected to the rubber strip 11. The bottom of the water tank 6 has a slot 12. The rubber strip 11 is inserted into the slot 12 to install the baffle plate 10. It can be removed during workpiece processing. A water pump 13 is fixedly connected to the inner wall of the bottom of the water tank 6. A water supply pipe 14 is fixedly connected to the output end of the water pump 13.
