Temperature controlled conveyer for plastic injection moldings comprises an inclined air permeable conveyer in a housing to which temperature controlled air flow is supplied

摘要

The conveyer belt is enclosed by a housing(1) with an inlet(8) at one end and an outlet at the other for transported moldings. Inlets(19) into the closed housing along the conveyer length allow heated air from a fan to enter the housing and vents(21) allow air escape. Air can pass through the conveyer belt in the vertical direction. Preferred Features: The regularly spaced inlets are connected to a fan(13) via a network of pipes(15). Air flow rate from the fan and flow in the pipes can be adjusted to maintain a set minimum pressure above atmospheric. Air inlets and outlets are located in the two housing sidewalls with inlets below and outlets above the supporting surface of the conveyer. Vents are slits extending along the housing length. Air from the fan is heated and filtered. The conveyer is inclined to the horizontal and follows the housing profile.
