Ultrasonic welding equipment for porous sound attenuation air inlet tube of non-woven fabric helical air filter

Abstract

The invention relates to ultrasonic welding equipment for a porous sound attenuation air inlet tube of a non-woven fabric helical air filter. The equipment comprises an electric control box, a winding rotating device, a feeding traveling device and a sizing device which are all arranged on a machine frame; the feeding traveling device is connected with a non-woven fabric roll and a nylon yarn roll; the winding rotating device is controlled by the electric control box to rotate; the feeding traveling device is controlled by the electric control box to travel along the direction of the winding rotating device and feeds non-woven fabric strips and nylon yarns into the winding rotating device to rotate and wind the non-woven fabric strips and the nylon yarns from inside to outside; and the sizing device is used for synchronously sizing the non-woven fabric strips wound on the winding rotating device. The non-woven fabric strips and the hard nylon yarns are adopted to be uniformly and slantingly wound on a core rod at intervals and are sized, adhered and formed in a matched mode. The ultrasonic welding equipment has a simple and compact structure, is convenient to operate, and has simple processes and a short forming period. The requirement on a certain rigidity required when an automobile engine and the air filter need to be randomly bent in the abutting process under different assembly working conditions can be met. The ultrasonic welding equipment has a long service life, can be recycled and has no waste pollution.

Description

technical field [0001] The invention relates to a production equipment for an air intake pipe of a non-woven fabric air filter, in particular to a welding equipment for welding a porous sound-absorbing air intake pipe of a non-woven fabric spiral air filter by means of ultrasonic waves. Background technique [0002] The structure of the traditional automobile air intake pipe is made of polypropylene injection molded parts connected to the car engine through a sealing strip. The polypropylene injection molded parts need to be customized according to the installation space in the car. There are many parts, high production cost, cumbersome assembly and poor applicability. Existing automobile air intake pipes use rubber bellows, which consume high energy consumption and high cost in processing, have low strength after bending and installation, and have poor anti-aging performance. Once aging and damage will greatly affect the service life of the engine, it cannot effectively ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that there is no guarantee for the quality of the non-woven fabric intake pipe formed by adhesive bonding, and the glued part cannot meet the requirements of ventilation and high temperature environment of the intake pipe, and it is easy to degumming and cracking, which affects the service life of the intake pipe. The invention provides A kind of ultrasonic welding equipment with simple structure, fast welding speed and stable forming of porous sound-absorbing intake pipe of non-woven spiral air filter is developed. The welded non-woven intake pipe has high overall strength and good anti-aging performance, which is suitable for air filtration. The use of porous sound attenuation and noise reduction
