Embodiment 1

[0030] Embodiment 1: as figure 1 with figure 2As shown, a continuous foaming device for amino sound-absorbing cotton, including a plastic foaming mold 1 with a rectangular foaming channel, a microwave system 2, a foaming air supply and outlet system 3, and a foaming unit of a foaming stainless steel shell 4, The foamed stainless steel shell 4 is set outside the plastic foaming mold 1, and the microwave system 2 is arranged outside the foamed stainless steel shell 4, specifically on the upper part of the foamed stainless steel shell 4 in this embodiment; the foamed air supply The air outlet system 3 is arranged on the outside of the foamed stainless steel shell 4, specifically on the top and left and right sides of the foamed stainless steel shell 4 in this embodiment; the microwave system 2 includes a power supply, a magnetron (ie microwave generator), a microwave The transmission pipe 21 (in this embodiment, the width*height of the microwave transmission pipe 21 is 250mm*13...

Embodiment 2

[0032] Embodiment 2: as figure 1 with image 3 As shown, a continuous foaming device for amino sound-absorbing cotton,

[0033] Compared with embodiment 1, the difference is:

[0034] The microwave system 2 also includes a regulator 213, the cross-section of the microwave transmission pipeline 21 is rectangular, and the regulator 213 is arranged on the outside of the foamed stainless steel casing 4 (in this embodiment, it is the upper part of the foamed stainless steel casing 4). On the outer walls of the left and right sides of the microwave transmission pipe 21 , the regulator 213 is a magnet acting on the left and right sides of the microwave transmission pipe 21 to improve microwave conduction behavior. In this embodiment, the small magnets whose position and spacing can be adjusted constitute the regulator 213. Specifically, the motor connects two small magnets through a synchronous belt, and the position and spacing are adjusted forward and backward along the left and ...

Embodiment 3

[0036] Embodiment 3: as figure 1 with Figure 4 As shown, a continuous foaming device for amino sound-absorbing cotton,

[0037] Compared with embodiment 2, the difference is:

[0038] The microwave system 2 also includes various mode distribution blocks 22, the mode distribution block 22 is a cuboid made of a material with a certain dielectric constant, usually plexiglass or urea-formaldehyde resin, and its dielectric constant is generally 2 to 4. In this embodiment, it is a plexiglass material, the size of which is like a brick (240mm in length, 120mm in width, and 60mm in height). The number and distribution position of the blocks are manually adjusted on the bottom of the foaming mold 1 according to the production form of the sound-absorbing cotton product. The shape of the product is related to the microwave intensity. If a certain position in the plastic foam mold 1 needs to increase the microwave intensity, place it below this position. The denser the placement, the g...

Abstract

The invention relates to a continuous foaming device for amino sound-absorbing cotton. The continuous foaming device comprises a foaming mold, a microwave system, a foaming air supply and air outlet system and a foaming unit of a foamed stainless steel shell, wherein the microwave system is arranged on the outer side of the foamed stainless steel shell, and the foaming air supply and air outlet system is arranged on the outer side of the foamed stainless steel shell; the microwave system comprises a power supply, a magnetron and a microwave transmission pipeline, and the tail end of the microwave transmission pipeline enters the interior of the foamed stainless steel shell to be located between the foamed stainless steel shell and a top plate of the foaming mold; and the microwave system further comprises strip-shaped distributors which are arranged in a cavity at the tail end of the microwave transmission pipeline, the cross sections of the strip-shaped distributors are isosceles triangles, and the strip-shaped distributors are arranged to enable wave-facing surfaces of the strip-shaped distributors to uniformly separate microwaves and transmit the microwaves to the two sides. According to the continuous foaming device, the plurality of wedge-shaped strip-shaped distributors with isosceles triangles are arranged in the cavity at the tail end of the microwave transmission pipeline, the microwaves are uniformly separated and transmitted to the two sides, so that the microwave uniformity is effectively improved.

Description

technical field [0001] The invention relates to the technical field of production of amino sound-absorbing cotton, in particular to a continuous foaming device for amino sound-absorbing cotton. Background technique [0002] Amino sound-absorbing cotton is a new type of sound-absorbing decorative material, widely used in aviation, aerospace, automobiles, and motor vehicles for sound absorption and noise reduction. It is generally produced by amino resin, especially melamine formaldehyde resin, through a continuous foaming process. The continuous foaming device used in the continuous foaming process includes a foaming mold with a foaming channel, a microwave system, and a foaming air supply. Wind system, foamed stainless steel shell, the microwave system is arranged on the upper side outside the foamed stainless steel shell, and the foamed air supply and outlet system is set on the upper side or lower side or left and right sides of the foamed stainless steel shell, so The mi...
