Intelligent polyurethane spraying device and spraying method thereof

Abstract

The invention discloses an intelligent polyurethane spraying device and a spraying method thereof, and belongs to the technical field of building construction. The device includes a moving mechanism,a head shaking mechanism, a spray gun and a controller, wherein the moving mechanism is arranged on a supporting mechanism to move horizontally and vertically under driving of a power mechanism; the head shaking mechanism is arranged on the moving mechanism to shake the head outwards at stop points at the two ends for spraying; the spray gun is fixed on the head shaking mechanism to spray a polyurethane raw material; the controller is used for controlling the power mechanism and the head shaking mechanism. The spraying method includes the following steps that 1, the controller controls a second servo motor to drive a spray gun support to move left and right along a horizontal guide rail so as to achieve horizontal spraying; the spray gun moves to the left stop point, and a rotary cylinderswings and drives the spray gun to swing to the left; the spray gun moves to the right stop point, and the rotary cylinder swings and drives the spray gun to swing to the right; 2, a first servo motoris controlled to drive a horizontal movement bracket to move upwards a set distance along a vertical guide rail, and then the step 1 is repeated.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an intelligent polyurethane spraying device and a spraying method thereof. Background technique [0002] In the field of building construction technology such as thermal insulation engineering and waterproof engineering, in order to improve thermal insulation and waterproof performance, it is often necessary to spray polyurethane on large areas such as walls and ceilings. [0003] At present, the traditional method is to adopt the construction method of polyurethane spraying device and manual operation spray gun. This way increases the construction cost, the labor intensity of the workers is high, the work efficiency is low, and the spraying effect is not ideal, and the quality control of the finished product is unstable. In the prior art, there is also a spraying device that can realize automatic spraying. Although it can realize automatic spraying, th...

Problems solved by technology

This method increases the construction cost, the labor intensity of the workers is high, the work efficiency is low, and the spraying effect is not ideal, and the quality control of the finished product is unstable.

In the prior art, there is also a spraying device that can realize automatic spraying. Although it can realize automatic spraying, there will be accumulation of raw materials at the stop points at both ends, such as Figure 4 As shown, not only is the polyurethane raw material wasted, but also the sprayed coating is thick on both sides and thin in the middle, and the connection is uneven, such as Image 6 As shown, the spraying effect is not ideal, and it is not beautiful

In addition, the spray gun needs to be turned off and then restarted at both ends of the pause point, which is not only inefficient, but also frequent shutdown will shorten the service life of the spray gun
