Building material spraying devices are a type of equipment specifically used for spraying operations in the construction field, designed to evenly spray paint or other liquid materials onto the surface of building materials to achieve the purpose of decorative, protective or functional coatings. These devices are widely used in spraying operations on various parts of buildings, such as exterior walls, roofs, floors, doors and windows.

[0003] Hollow pipe is a kind of building material widely used in the fields of construction and engineering. Hollow pipe can effectively insulate heat and sound, and is suitable for building structures that require good thermal insulation. Hollow pipe needs to be sprayed during processing.

Most spraying devices include a frame, a spraying component for spraying the hollow pipe, and a clamping component for fixing the hollow pipe. The existing spraying device needs to clamp the two ends of the hollow pipe into the However, when fixing round or heavy hollow tubes, the two traditional straight clamps of most clamping assemblies cannot adapt well to the shape and size of hollow tubes. The hollow tube can easily fall off from the clamping assembly only by clamping with traditional straight clamps. If the hollow tube falls off during spraying, the spraying assembly may miss some areas, resulting in uneven coating, affecting product quality, and requiring the operator to reposition and fix the hollow tube, which reduces production efficiency to a certain extent.
