Acoustic panel top camber material distribution dressing device and method

Abstract

The invention provides an acoustic panel top camber material distribution dressing device and method. According to the structure of the device, a front side wall plate of a distribution box is provided with a servo motor, a scraper plate, a connection disc, an adjustable connection rod and a control system; the scraper plate is of a long-strip-shaped plate structure, the lower end of the adjustable connection rod is hinged to the upper end face of the scraper plate, the upper end of the adjustable connection rod is fixedly connected to the edge of the disc face of the connection disc, and the axial center of the connection disc is connected with an output shaft of the servo motor; under the drive of the control system, the servo motor can drive the connection disc to rotate, and then the adjustable connection rod drives the scraper plate to do up-down linear motion; the distribution box can move forwards or backwards under the effect of a distribution box oil cylinder; and the materials distributed on the acoustic panel top camber can be trimmed through the scraper plate, and therefore the surface of the materials can accord with the shape of the acoustic panel top camber. By means of the acoustic panel top camber material distribution dressing device, the height and longitudinal section shape of the materials in a lower die cavity can be controlled during high-speed distribution of the distribution box, and the internal structure of a loose-structure concrete product is uniform after pressure vibration forming.

Description

technical field [0001] The invention relates to the technical field of making sound-absorbing panels, in particular to a trimming device and a trimming method for curved surface cloth on a sound-absorbing panel for a sound barrier. Background technique [0002] With the rapid development of my country's high-speed railway, new technology and equipment for railway construction, new materials and new products are emerging in an endless stream, and have achieved considerable development along with high-speed railway. Among them, the sound barrier sound-absorbing panel with new environmental protection material ceramsite as the main raw material is a specific application of new materials and technologies in this field, which greatly promotes the overall upgrade of railway functions, and has been tested. Ceramsite sound-absorbing panels have good sound-absorbing and noise-reducing effects, and are maintenance-free for life. From the perspective of long-term development, they have...

AI Technical Summary

Problems solved by technology

[0003] One of the purposes of the present invention is to provide a device for trimming curved surface fabrics on sound-absorbing panels. This device is designed to solve the problems caused by different batches of raw materials due to inconsistent density, particle size, and different compression ratios during the development of an automatic production line for sound-absorbing panels. Developed for the problem of inconsistent product height, the device can solve the problem of inconsistent internal density of products caused by flat fabrics

[0004] The second purpose of the present invention is to provide a method for trimming the curved surface of the sound-absorbing panel, through which the trimming of the curved surface of the sound-absorbing panel can solve the problem of inconsistency in the internal density of the product caused by the flat fabric
