AI Technical Summary

Technical Problem

In existing technologies, pearl cotton boards lack positioning structures during the hole-making process, which makes the boards prone to deformation and displacement, potentially leading to a decline in hole-making quality.

Method used

An opening positioning device was designed, comprising a pressing positioning plate, a telescopic device, and a rotating pushing tensioning plate. These devices enable the positioning of the EPE foam board, the telescopic movement of the EPE foam board, and the positioning of the board itself. These devices improve the stability of the EPE foam board and the quality of the opening.

Benefits of technology

It improves the stability and drilling quality of EPE foam boards during the drilling process, enhances the positioning effect of EPE foam boards after drilling, and improves drilling efficiency and quality.

Abstract

The utility model relates to the technical field of trepanning positioning equipment, and discloses a trepanning positioning device for pearl wool production, which comprises a trepanning frame body, a placing plate is arranged in the trepanning frame body, and a plurality of trepanning receding openings are formed in the placing plate in a penetrating manner. A first telescopic device with a telescopic effect is fixedly installed on the upper portion of the trepanning frame body, the telescopic end of the first telescopic device extends into the trepanning frame body, a first moving plate is fixedly installed at the telescopic lower end of the first telescopic device, a second moving plate is arranged below the first moving plate, and a plurality of first connecting columns are fixedly installed between the second moving plate and the first moving plate; a pressing positioning plate capable of moving up and down is arranged below the second moving plate, and a plurality of trepanning tools matched with the trepanning receding openings are fixedly installed on the lower portion of the second moving plate. According to the utility model, the pressing and positioning plate moves downwards to press and position the pearl wool plate, so that the stability of the pearl wool plate is ensured when the pearl wool plate is perforated, and the quality effect of the perforated pearl wool plate is further improved.
