Description

Technical Field

[0001] The utility model belongs to the technical field of sound insulation pad processing, in particular to a trimming device for processing sound insulation pads. Background Art

[0002] Sound insulation pads play an important role in car interiors and can effectively reduce the entry and spread of noise. The trimming device for sound insulation pad processing is a device specially designed for trimming the edges of sound insulation pads. It is usually equipped with a precision cutting system that can accurately control the path of the cutting tool or laser beam to achieve smoothing of the edges of the sound insulation pads. The device has a high degree of automation and is easy to operate, which effectively improves the production efficiency and quality of the finished product of the sound insulation pads. Through trimming, the edges of the sound insulation pads are smoother and free of burrs, meeting the requirements of product appearance and performance. This device plays an important role in the sound insulation pad production line and is an indispensable part of modern sound insulation material processing.

[0003] A Chinese patent with announcement number "CN221539979U" discloses a high-temperature resistant automotive sound insulation pad processing and cutting device, including a base, an operating table, a cutting assembly and a positioning assembly.

The positioning assembly is symmetrically arranged on both sides of the operating table and can position the sound insulation pad; the positioning assembly includes a slide rail, a plug column, a card strip, a bolt, a shell, a spring, a connecting block, a torsion spring, a pressing block and a friction pad.

When the limiting mechanism needs to be adjusted according to the size of the sound insulation pad, the limiting structures at the four corners also need to be adjusted in position.
