Description

A kind of automatic bag sponge device

technical field

The invention relates to the field of wire production, in particular to an automatic sponge wrapping device.

Background technique

On the market, the wires in many instruments, including speakers, need to be covered with a layer of sponge to prevent shock and damage. The sponge used is a sponge sticker with self-adhesive, which is sticky on one side. Use release paper to protect the stickiness before wrapping the wire, and remove the release paper before wrapping the wire. In the prior art, the wires are still manually wrapped into the sponge strips. For example, thousands of wires need to be wrapped into sponges in the speaker factory every day. The workload is huge, and the staff keeps repeating boring actions. The quality of the sponge-packing work completed in different time periods cannot be consistent, and consumes a lot of manpower, which is not conducive to improving production efficiency.

The linear slide rail cylinder includes a cylinder body, a slide rail and an L-shaped slide block. The slide rail is fixed on the cylinder body. One side of the L-shaped slide block is installed on the slide rail and can slide along the slide rail. The side is fixedly connected with the piston rod end of the cylinder, and the L-shaped slider slides back and forth on the slide rail as the piston rod stretches and contracts.
