Description
Technical Field
The utility model relates to an air cooling device for a production line of a cavity EVA (ethylene vinyl acetate) mesh-sandwiched iron sheet, which is a device matched with the production line of the EVA mesh-sandwiched iron sheet.
Background
Because vehicles run on various outdoor highways and tracks, vibration and noise can be generated under the influence of various conditions on the roads, and for example, various cavities of automobiles, electric vehicles, high-speed rails, subways and aircrafts can generate resonance and resonance in motion. The resonance, the sympathetic response problem that the cavity produced need a syllable-dividing inflation to glue the piece, will give sound insulation the inflation and glue the piece and fix in the cavity, and the assembly back is toasted with the high temperature of later process, and the foaming sheet that the piece was glued in the inflation that gives sound insulation begins the inflation, fully fills the cross section of cavity, plays separation resonance effect, reaches the effect of making an uproar that gives sound insulation and fall.
The sound insulation expansion rubber block in the prior art is completed by adopting a twice injection molding process, firstly, a nylon 66 framework is subjected to injection molding by an injection molding machine, a cavity for injection molding of EVA (ethylene vinyl acetate) foaming material is reserved, and then, the reserved cavity is filled with the injection molding of the EVA foaming material by the injection molding machine to prepare a finished product.
Because the cavity size is not of uniform size, divide into about again, so, satisfy the syllable-dividing expanded rubber block that various cavities need, need make several sets of plastic mold, wherein secondary injection mold occupies half, and the mould expense that drops into is higher, production cycle length, and is inefficient, and product cost is high.
Therefore, it has been the subject of research and research by manufacturers to provide a sound-insulating expanded rubber block which has a simple structure, a simple and convenient process, a low cost, and effects of blocking resonance in a cavity and achieving sound insulation and noise reduction.
Disclosure of Invention
In view of the prior art, the utility model provides an air cooling device that is used for cavity EVA to press from both sides mesh eye iron sheet production line is the key corollary device of EVA presss from both sides mesh eye iron sheet production line. The air cooling device is matched with a production line to complete one-time injection molding processing of the EVA mesh iron sheet, namely, after the EVA foaming material is coated on a blank mesh iron sheet through an extrusion die, the EVA foaming material is firstly cooled down and cooled down through the air cooling device for one time, so that the EVA is solidified on the mesh iron sheet with certain hardness, and then cooled down and sized through a pressure sizing tractor for the second time, and finally a finished product of the EVA mesh iron sheet with the mesh is formed.
When the sound insulation and noise reduction device is used, the sound insulation and noise reduction device is punched into different shapes according to the shape of the cavity, is arranged in the cavity, and expands and foams at high temperature through EVA to play a role in isolating resonance, so that the sound insulation and noise reduction effects are achieved.
The utility model discloses a realize above-mentioned purpose, the technical scheme who adopts is: the utility model provides an air cooling device that is used for cavity EVA to press from both sides mesh iron sheet production line which characterized in that: the air cooling device comprises an electric fan, a hood, a bracket and a speed regulator;
the two electric fans are fixed on the support through connecting pieces respectively, a hood is fixed on each electric fan, the two electric fans are symmetrically arranged at intervals, the speed regulators are fixed on the support, and the two electric fans are connected with the speed regulators respectively.
The utility model is characterized in that: the air cooling device is a key matching device for producing qualified EVA mesh iron sheet materials on an EVA mesh iron sheet material production line, after an EVA foaming material is coated on a blank mesh iron sheet through an extrusion die, the EVA foaming material is cooled once through an air cooling device to enable the EVA to be solidified on the mesh iron sheet materials with certain hardness, and then the EVA mesh iron sheet materials are cooled and sized secondarily through a pressure sizing tractor to finally form an EVA mesh iron sheet material belt finished product.
The air cooling device provides reliable guarantee for the finally manufactured EVA mesh-sandwiched iron sheet to meet the design quality requirement.
The EVA mesh-sandwiched iron sheet is formed by one-time injection molding through a production line, so that the processes of injection molding of nylon 66 frameworks and secondary injection molding of EVA by a plurality of injection molding machines in the prior art are replaced, the labor, material resources and finished product cost are saved, and the production efficiency is improved by more than 60%.
