Problems solved by technology

This results in belt material being lost on the heating rods reducing the quality of the resulting joint
and material adhering to the heater rod must be removed

Embodiment Construction

[0019] figure 1 A splicing tool embodying features of the invention and having figure 2 with image 3 in the heating rod. The tool 10 is generally bisymmetrical and left-right symmetric, comprising left and right jaws 12, 13 having a plurality of holes 14, 15 at each end of the tool. The holes in the left jaw line up with the holes in the right jaw. Transverse rails 16 extending through holes 14, 15 and supported in the frame of the splicing tool align the jaws and provide support guides along which the jaws move towards and away from each other. The upper platform 18 on the jaws 12, 13 has a plurality of detents 20, 21 which are inwardly recessed in its top surface to interface with, for example, transverse ribs on the non-planar side of the conveyor belt 24 to be spliced. 22 structure to match. for image 3 In the conveyor belt shown, the drive ribs 22 are received in wider slots 20 in the upper platform 18 of the jaws. The narrow groove 21 accommodates a belt with n...

Abstract

A belt splicer for butt-welding conveyor belts and methods for its operation. The belt splicer has clamp jaws that close to contact the butt edges of two belt sections against opposite ends of a heating wand and to hold the two melted butt edges together as they weld to each other. A toggle linkage assembly locks the clamped jaws closed and stores energy in a spring mechanism. The toggle linkage assembly allows the rapid release of the spring energy to accelerate the clamp jaws open to pull the melted butt ends rapidly away from the sides of the wand to avoid sticking. In another version, an air cylinder is used instead of the toggle linkage assembly and spring mechanism to close and rapidly open the splicer.

Description

technical field [0001] The present invention relates generally to splicing tools for thermally joining butt edges of plastic conveyor belts, and more particularly to splicing tools for quick release of butt edges from both sides of a heating rod. Background technique [0002] The splicing process is commonly used to weld the butt ends of two thermoplastic belt sections together. A conventional process includes a pair of clamps, each holding one of the two strap segments. The pair of clamps hold the strap segments tightly such that the butt ends are opposed to each other with a gap. The heater rod is moved into this gap, and the two clamps are closed until the butt end of the band segment touches the opposite side of the heater rod. Once the heat from the heating rod has sufficiently softened or melted the butt end, the jaws are withdrawn so that the heating rod can be removed. The jaws are then moved toward each other until the softened or melted butt ends meet. The clam...
