Embodiment Construction

[0015] figure 1 A belt splicer embodying features of the invention is shown in . The splicer 20 includes a rod positioner and jaws 21 supported between a pair of frame rails 22 . Handles 24 attached to the frame 22 at each end contribute to the portability of the splicer. The jaw 21 is divided into a right jaw 23 and a left jaw 23', each jaw being a nearly identical mirror image of the other with respect to a vertical plane passing through the axial centerline 26 of the splicer. Each half 23, 23' of the jaws 21 includes an axis 28, 28' extending parallel to the centerline 26 in the width direction of the splicer. Rotation of the shaft opens and closes the jaws 21 . Each jaw 23, 23' also has an upper deck 30 on which the two belt end sections to be spliced ​​together sit. The belt end sections may be opposite ends of a single belt or the ends of individual belt sections to be spliced ​​together. Rotation of the shafts 28, 28' translates the left jaw 23 and the right j...

Abstract

A belt splicer for splicing butt ends of thermoplastic belts together. The splicer uses multiple cranks with heavy springs to close and quickly open jaws that hold the butt ends of the belt in place against a heating rod for melting and against each other for melting. The ends are welded together. The quick opening of the jaws also lowers the rod, which is locked in place by the rod lock during the melting of the butt ends.

Description

Background technique [0001] The invention relates to a splicing tool for thermally joining butt edges of plastic conveyor belts. [0002] Splicing presses are used to weld the butt ends of two thermoplastic belt sections together. A conventional press includes a pair of clamps, each clamping one of two belt segments. The clamp securely holds the belt sections with the butt ends facing each other across a gap. The heating rod is moved into the gap, and the two clamps are brought together until the butt ends of the belt sections contact the opposite side of the heating rod. Once the butt ends are sufficiently softened or melted by the heat of the rod, the clamps are retracted and the rod is moved out of the way. Then, move the clamps toward each other until the softened or melted butt ends meet. The clamps hold the butt ends together as the joint at their interface cools. U.S. Patent No. 8,596,622 issued December 3, 2013 to Robert G. Guttenberg discloses a method for thermo...
