Automatic glue spraying and compounding machine for automobile trunk carpet production and production method

Abstract

The invention discloses an automatic glue spraying and compounding all-in-one machine and a manufacturing method for automobile trunk carpet production. A template of the automatic glue spraying and compounding all-in-one machine is moved by a horizontal sliding mechanism so that the purpose of horizontal displacement glue spraying of a polypropylene cellular board on the template can be achieved through a glue spraying device. The glue spraying device is moved by a vertical sliding mechanism so that the purpose of vertical displacement glue spraying of the polypropylene cellular board on the template can be achieved through the glue spraying device. Meanwhile, the glue sprayed polypropylene cellular board on the template is glued to a sound insulation felt. The glued sound insulation felt and the polypropylene cellular board on the template are quickly transferred to the position below a pressing plate by the horizontal sliding mechanism. The pressing plate is automatically activated and quickly pushed by a power unit so that further pressing, compounding and molding can be carried out on the glued sound insulation felt and the polypropylene cellular board. According to the automatic glue spraying and compounding all-in-one machine and the manufacturing method for the automobile trunk carpet production, the compounding fastness and the production efficiency of an automobile trunk carpet are improved, and the compounded and molded automobile trunk carpet is good in operation performance.

Description

technical field [0001] The invention relates to an automatic glue-spraying compound machine and a production method for the production of car trunk carpets in the automatic production industry. Background technique [0002] With the progress of society, my country has transformed from relying on low-labor manual manufacturing to an automated industrial development route, especially the industry of automatic glue spraying and compound molding of automobile trunk carpets has made great progress, and no matter how many glues are sprayed The market demand for high-performance automobile trunk carpets formed by composite molding is also increasing. At present, polypropylene honeycomb panels have good lightweight and environmental protection characteristics, and are widely used in the design and production of automobile trunk carpets. In order to improve automobile The sound-absorbing and vibration-reducing performance of the trunk carpet further improves the driving comfort. The so...

Problems solved by technology

[0003] In the prior art, the polypropylene honeycomb panel in the car trunk carpet and the sound insulation felt are compounded by glue, and among the organic, inorganic, water-based and other glue systems used in the compounding, the propylene-based glue suitable for the polypropylene honeycomb panel Few, and at the same time it is difficult to meet the requirements of environmental protection, strength and temperature resistance, so hot-melt adhesives are used for compounding, but the opening time and curing time of conventional hot-melt adhesives will vary with the temperature of the glue, the amount of coating, and the bonding force. At the same time, the coating amount and coating path of the luggage carpet are long, the bonding pressure should not be too high (the honeycomb cavity structure needs to be protected), and the glue temperature should not be too high (the heat distortion temperature of engineering polypropylene is 145-155°C), and under the above conditions, it is difficult to make a good composite of polypropylene honeycomb panels and sound insulation felts, so a related device and process that can quickly realize glue spraying, coating and compounding are needed
