Problems solved by technology

However, when the above-mentioned mixing device mixes filamentary materials (such as glass fiber) and powdery materials (such as gypsum powder), the polyurethane cannot be fully atomized, and the mixing effect is not good, and the feeding method of polyurethane is relatively direct and cannot be precisely controlled. The pressure of the polyurethane raw material, the mixing part of the polyurethane raw material and other raw materials is uniform

Embodiment 1

[0040] Such as Figures 1 to 10 shown

[0041] The mixing head device includes a feeding pipe 5 , a main mixing seat 1 , an auxiliary mixing seat 7 , a spraying control assembly, a cleaning control assembly, two material pressure regulating valves 2 , a mixing core 8 and a telescopic cylinder 6 .

[0042]The main mixing seat 1 also has an inner hole that runs through its upper and lower end faces. The bottom of the inner hole of the main mixing seat 1 is provided with an outlet. The side wall of the main mixing seat 1 has a horizontal main feeding through hole 1b, and the main feeding through hole 1b extends On the inner wall of the main mixing seat 1, there are two groups of material holes in the main mixing seat 1, which correspond to the two material pressure regulating valves 2 one by one, and the two groups of material holes are horizontally distributed in the main feeding through hole 1b On both sides, each group of feed holes includes an independent feed hole 1c and di...

Embodiment 2

[0061] The difference between the present embodiment and the first embodiment is only that the mixing core is not included in the present embodiment, and the inlet of the auxiliary mixing seat of the mixing head device is not communicated with high-pressure air, but other powders (such as gypsum powder, etc.), Feed pipe 5 is loaded onto silk plug then and uses as common conventional " L " type mixing head. It can produce soft foam sponge; hard foam imitation wood; semi-rigid foam insulation board pipes, etc., which greatly expands the applicable environment of this mixing head device and meets the processing needs of different materials.

Abstract

The invention provides a polyurethane multifunctional high-pressure mixing head device. According to the device, a main feeding through hole is formed in the side wall of a main mixing seat, a feeding hole and a discharging hole are further formed in the main mixing seat, a cavity is formed in a valve shell of a material pressure adjusting valve, a valve element and a pressure spring are installed in the valve shell, an atomizing nozzle is formed between the valve element and a valve body outlet of the valve shell, a material spraying control piston rod of a material spraying control assembly extends into the main feeding through hole, a main air inlet through hole is formed in the side wall of the main mixing seat, an air inlet hole is further formed in the main mixing seat, an air injection control piston rod of a cleaning control assembly extends into the main air inlet through hole, the tail end of a material conveying pipe extends into an inner hole of the main mixing seat; an auxiliary mixing seat is fixedly connected to the lower side of the main mixing seat, a buffer cavity is further formed in the auxiliary mixing seat, an inlet is formed in the auxiliary mixing seat, and a mixing opening is formed in the inner wall of the auxiliary mixing seat. Through cooperation of the material pressure adjusting valve and the material spraying control assembly, accurate control over the polyurethane raw material spraying amount is achieved, and the device is suitable for mixing polyurethane and solid materials and suitable for industrial application.

Description

technical field [0001] The invention relates to a polyurethane multifunctional high-pressure mixing head device. Background technique [0002] Polyurethane waste recycling technology uses polyurethane waste to be processed into powder or granules to complete the regeneration operation. It is necessary to use a mixing device to process the material into powder or granules for transportation and spraying, so as to avoid the degradation of the processing performance of the processing components on the material, but at present The mixing device for mixing polyurethane and solid materials has complex structure, poor mixing uniformity and low mixing efficiency, and is not suitable for industrial application. [0003] The Chinese patent "mixing core, a mixing device using it to mix polyurethane and solid materials" with application number 201811290823.7 discloses a mixing device, including spray gun parts for polyurethane spraying and horizontal arrangement, solid materials falling...
