AI Technical Summary
The surface sandblasting equipment used in the current folding chair manufacturing process has a relatively closed structure, which makes it difficult to remove and clean the sandblasted debris in a timely manner, and the sealing performance is insufficient, which can easily cause a large amount of dust to overflow.
A sandblasting device was designed, comprising an installation frame, a collection trough, a moving frame, and a synchronizing rod. By pulling the pull ring, the synchronizing rod is slidable, and the support bar rotates in the installation groove, collecting debris into the collection trough. A foldable, telescopic intercepting cloth is used to prevent dust from escaping, ensuring that the dust is completely confined within the device.
It achieves efficient collection of sandblasting debris and effective dust containment, protecting the safety of the operating environment and improving production efficiency and ease of cleaning.
