Abstract:
1. A self-contained, portable conveyor belt splicing apparatus for joining conveyor belt ends together, the portable conveyor belt splicing apparatus comprising: a housing assembly including upper and lower housing frames having unclamped and clamped positions relative to the belt ends; upper and lower platens of the upper and lower housing frames, respectively, each of a metallic material for being clamped on the belt ends with a clamping force with the upper and lower housing frames in the clamped position and without a substantially rigid heat absorbing member between the platens and the belt ends; upper and lower heating elements for heating the upper and lower platens with the upper platen being between the upper heating element and the belt ends and the lower platen being between the lower heating element and the belt ends; an on-board inflatable bladder mounted to the housing assembly; an on-board air compressor mounted to the housing assembly for supplying the bladder with pressurized air to drive the clamped lower platen against the belt ends to increase clamping force applied thereto avoiding the need for an external pressurized air supply for supplying the pressurized air to the bladder; and an on-board fan device mounted to the housing assembly operable to draw ambient air for generating high volume airflow along the clamped platens and belt ends avoiding the need for an external air supply for supplying the housing assembly with air for the clamped platens and belt ends; an on-board control system mounted to the housing assembly having circuitry connected to the heating elements and being configured to receive power from different types of standard power supplies and supply the power to the heating elements, the on-board air compressor, and the on-board fan device; and an on-board user operated control of the control system mounted to the housing assembly operable to control the heat applied by the heating elements to the respective platens.
