Embodiment 1

[0034] Such as figure 1 Shown, a kind of production technology of shock-absorbing and noise-reducing sound-insulating pad, comprises the following steps:

[0035] (1) Cut the sound-proof base material into a section by cutting machine and lay it in the steam mold, close the steam mold, inject the steam in the steam machine into the sound-proof base material through the steam mold, and control the pressure of the steam machine to 32MPa, steam The heating temperature of the mold is controlled at 236°C, and the heating time is kept at 35s;

[0036] (2) The sound-insulating base material that has been steamed in step (1) is grabbed by the robot and placed in the drying and gluing integrated machine. After drying and gluing, it is discharged from the drying and gluing integrated machine. The manipulator at one end of the feed port grabs and places it in the cold forming mold. The sound insulation base material in the cold forming mold includes two layers of the same sound insulati...

Embodiment 2

[0045] A production process of a shock-absorbing and noise-reducing sound-insulating pad, comprising the steps of:

[0046] (1) Cut the sound insulation substrate into a section by cutting machine and lay it in the steam mold, close the steam mold, inject the steam in the steam engine into the sound insulation substrate through the steam mold, and control the pressure of the steam engine to 35MPa, steam The heating temperature of the mold is controlled at 240°C, and the heating time is kept at 30s;

[0047] (2) The sound-insulating base material that has been steamed in step (1) is grabbed by the robot and placed in the drying and gluing integrated machine. After drying and gluing, it is discharged from the drying and gluing integrated machine. The manipulator at one end of the feed port grabs and places it in the cold forming mold. The sound insulation base material in the cold forming mold includes two layers of the same sound insulation base material. Both layers of sound i...

Embodiment 3

[0056] A production process of a shock-absorbing and noise-reducing sound-insulating pad, comprising the steps of:

[0057] (1) Cut the sound-proof base material into a section by cutting machine and lay it in the steam mold, close the steam mold, inject the steam in the steam machine into the sound-proof base material through the steam mold, and control the pressure of the steam machine to 38MPa, steam The heating temperature of the mold is controlled at 45°C, and the heating time is kept at 25s;

[0058] (2) The sound-insulating base material that has been steamed in step (1) is grabbed by the robot and placed in the drying and gluing integrated machine. After drying and gluing, it is discharged from the drying and gluing integrated machine. The manipulator at one end of the feed port grabs and places it in the cold forming mold. The sound insulation base material in the cold forming mold includes two layers of the same sound insulation base material. Both layers of sound in...

Abstract

The invention discloses a production process of a shock absorption, noise reduction and sound insulation pad. The invention relates to the technical field of soundproof material processing. The production process comprises the steps of steaming, heating and drying, gluing, cold forming die forming, cutting, quality testing, packaging, warehousing and the like. Meanwhile, the invention further discloses a drying and gluing all-in-one machine for drying and gluing treatment. According to the invention, the ratio of each component of the sound insulation material is optimized, on the premise thatthe thickness of the sound insulation material is not increased, and in cooperation with an adaptive production process, namely, steam is pumped at a certain steam pressure and temperature for a certain period of time to enable the sound insulation pad to be fluffy, the drying and gluing all-in-one machine to achieve heating, drying, gluing and die assembly forming under a certain pressure, and finally the obtained sound insulation pad product has excellent sound insulation and shock absorption effects.

Description

technical field [0001] The invention belongs to the technical field of sound-insulating material processing, and in particular relates to a production process of a shock-absorbing and noise-reducing sound-insulating pad. Background technique [0002] Sound insulation / sound-absorbing materials are widely used in automobiles, home appliances and other fields because of their good sound absorption, sound insulation and shock absorption effects. Such as patent publication number is CN106839385A a kind of manufacturing process of air-conditioning secondary noise reduction sound-absorbing board and patent publication number is a kind of automobile sound insulation and heat insulation pad and production process thereof of CN105196663B. [0003] At present, there are all kinds of sound insulation materials on the market, but due to the limitation of sound insulation material performance improvement technology, in order to obtain the expected sound insulation effect, it is often nece...
