An apparatus for spraying fluid phase color is integrated into a cladding manufacturing machine and synchronized with the manufacturing process. The apparatus is attached to the basket through which the concrete of the claddings is poured into a mould; color spraying initiates after completing the concrete filling phase of the manufacturing of the cladding and the basket retreats to its starting point. Color guns, attached to the basket, connect to color buckets and pump and condensed air pumps to deliver sprayed fluid color onto the top surface of the claddings. A control unit controls the color spraying via a sequential, parallel or pre-selected program or set of values of parameters that determine the final design or pattern on the claddings surface.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

A wipe dispenser for use in metering out consistent doses of a composition onto a disposable wipe includes a mixing and dispensing assembly. The assembly has a vessel holding a first liquid for the composition and a first pump to convey the first liquid. A bottle having a second pump to convey a second liquid of the composition is stored within the bottle. A funnel arrangement is in downstream communication with the first pump and second pump. The funnel arrangement includes a mixing chamber for mixing the first and second liquids and a dispensing funnel in communication with and downstream of the mixing chamber. A wipe can be pulled through the dispensing funnel and wetted with a mixture of the first liquid and second liquid from the mixing chamber. A push bar attached to the funnel arrangement can selectively apply the force to actuate the first pump and second pump.

An electrostatic spray device includes an electrostatic mixing chamber and an electrode pair in the electrostatic mixing chamber. The electrostatic mixing chamber receives an airflow that is driven by a fan of the electrostatic spray device. The electrostatic mixing chamber also receives a flow of fluid from a reservoir of the electrostatic spray device. The electrode pair is configured to apply electrostatic charge to droplets of the fluid suspended in the airflow. A voltage level of the electrostatic charge is adjustable responsive to a first DC output from a first DC convertor. A flow volume of the fluid from the reservoir is adjustable responsive to a second DC output from a second DC convertor. In some cases, a control unit of the electrostatic mixing device modifies the first or second DC outputs based on a target level of the voltage level or the flow volume.

A system and method for a vibrating paint strainer stand that enables the user to effectuate the flow of paint through a paint strainer by vibration whereby the paint strainer is positioned in a paint strainer holder on the stand such that one or more vibration motors attached on a neck opposite of the holder can provide vibration to the paint strainer.

The present disclosure relates to a 3D printer for construction for print-molding various structures, in which a main pipe 30 for transferring a filament material 31 therein is installed inside a nozzle 10 for discharging a printing material, such as concrete or mortar, to enable co-printing of the filament material 31 with the printing material while embedded in the printing material.

According to the present disclosure, in constructing a structure by a 3D printer for construction, a printing material embedded with the filament material 31 as reinforcing material may be printed, and as a result, the effects of reinforcing tensile strength of the printed object and inhibiting crack of the printed object may be obtained.
