ABSTRACT:
A scrap collector is comprised of a separator, a ventilating device, a chipping collecting container, a collecting bag, and a communicating pipe. The separator includes an air chamber, an inlet communicating with the air chamber, and a bottom hole communicating with the air chamber. The ventilating device is mounted on the separator and is provided with an outlet, generating an airflow flowing towards the outlet. The chipping collecting container is mounted under the separator, including an opening connected with the bottom hole of the separator. The collecting bag is mounted inside the chipping collecting container, including an opening in communication with the air chamber. An airtight room is defined between the chipping collecting container and the collecting bag. The communicating pipe has two ends respectively communicating with the air chamber and the room. Accordingly, the pressure inside the collecting bag and the room remains equal.
