Abstract

A continuous feeder apparatus applied in a vacuum process, which is to be disposed separately with channels at two end of a main body to provide for penetrating and placing a material belt, and disposed in the interior of a roller set containing an upper roller and a lower roller to provide for clamping the transportation material belt. A sealing mechanism is disposed between the roller set and the channels of the main body. The sealing mechanism is disposed on the side wall above the channel of the main body with the upper sealing member capable of being elastically connected to the circular surface of the upper roller and disposed on the side wall beneath the channel with the lower sealing member capable of being elastically connected to the circular surface of the lower roller. Additionally, the left and right sides of the channel are separately disposed with the side sealing members so that the two side sealing members can respectively elastically urge against the end fringes of the upper and lower rollers and the side fringes of the upper and lower sealing members to form the vacuum auxiliary cavity chamber connecting to the extraction apparatus to be capable of being disposed at the input end and output end of the vacuum process equipment to carry out the continuous transportation of the material belt of the vacuum process; thus, the present invention not only can effectively ensure the block-up of gas to be advantageous to carry out the vacuum process processing of the material belt, but also can make the upper/lower sealing members keep proper urging pressure with the upper and lower rollers to reduce the abrasion to further achieve the practical benefits of enhancing the vacuum closeness and the service life.
