The disadvantages of this are: 1) The production cycle of a single part is long, and the reheating time of the oven and the molding cooling time are about 300 seconds, that is, the production cycle of a single part is about 300 seconds; 2) The reheating of the oven requires high energy consumption; 3) The semi-finished felt is moved to the production workshop, with many stations and many processes
Aiming at such production methods with high energy consumption and various high costs, the present invention proposes an ultra-rapid prototyping device for sound insulation felt and its application

Embodiment
[0034] Such as Figure 1 to Figure 8 As shown, an ultra-rapid prototyping device for sound insulation felt, the device includes a felt material distribution mesh mold 2, an oven heating mesh mold 3, a rapid cooling forming mesh mold 4 and a punching die 5 connected successively by a conveyor belt 6, and the felt material At the entrance of the distribution mesh mold 2, a pair of traction rollers 1 rotating forward and backward are provided. The cavity of the felt material distribution mesh mold 2 is provided with 10 independent spaces 21 sequentially from front to back, and each space 21 is provided with an independent damper 22 . The oven heating mesh mold 3 includes an upper mold 31 and a lower mold 32, and the lower mold 32 is provided with a blowing port. The oven heating mesh mold 3 has two functions, one is to heat the cotton cake to melt the chemical fiber, and the other is to preform the cotton cake to obtain a felt blank. The rapid cooling forming mesh mold 4 compri...

The invention relates to an ultra fast forming device of deadening felt and application of the ultra fast forming device. The ultra fast forming device comprises a hair felt material distribution mesh mold, a drying oven heating mesh mold, a fast cooling forming mesh mold and a punching mold which are sequentially connected through a conveying belt, wherein the inlet part of the hair felt material distribution mesh mold is provided with a pair of traction rollers in positive and negative rotation, ten independent spaces are sequentially arranged in a die cavity of the hair felt material distribution mesh mold from the front side to the back side, and each space is provided with an independent air valve. Compared with the prior art, the ultra fast forming device and the application have the advantages that the deadening felt production process is completed within one minute, the ultra fast deadening felt production is realized, the production efficiency is greatly improved, the production cost is reduced, and the production level of parts is in the leading position in industry.
Description
technical field [0001] The invention relates to a device for producing sound-insulating felts, in particular to an ultra-rapid prototyping device for sound-insulating felts and its application. Background technique [0002] At present, the production process of sound insulation felt is as follows: the semi-finished flat felt of sound insulation felt is produced on the production line, and then transported to the molding mold workshop for molding and punching. The process is roughly like this: the first step, felt production, felt production It is completed on the felt production line. The felt production line needs to mix all kinds of fibers evenly, card them, air-form them into a net, and then heat them in an oven so that the chemical fibers in the wool net are semi-melted, and then the bonded cotton fibers are cooled to form a felt, that is, to produce special-shaped sound insulation felt. The semi-finished product; the second step is forming and punching, the semi-finishe...
