Wire twisting structure of strip coil bundling machine

Abstract

The invention relates to a bundle wire kinking mechanism for a strip steel coil bundling machine, which mainly comprises a big bodywork, a small bodywork and an oil cylinder, and is characterized in that a positioning mechanism is arranged on the small bodywork capable of moving upwards and downwards along the big bodywork; driving roller wheels of the big bodywork are horizontally arranged on a horizontal rail of a stander of the bundling machine; a pedestal of the oil cylinder is fixedly arranged on the stander of the bundling machine, a piston rod of the oil cylinder is fixed at the bottom of the big bodywork, the pedestal of the oil cylinder is fixed on the big bodywork, the piston rod of the oil cylinder is fixed on the small bodywork, and the driving roller wheels of the small bodywork are in sliding contact with a vertical rail arranged on the big bodywork; the space between the head part of the right end of the positioning mechanism and the outer diameter of a strip steel coil is L1; and the space between the head part of the right end of the positioning mechanism and a central hole of the strip steel coil is L2, and the space between the head part of the right end of the positioning mechanism and two lateral surfaces of the strip steel coil is S. The bundle wire kinking mechanism has the advantages that the spaces between the positioning mechanism and the outer diameter as well as the central hole of the strip steel coil are adjustable, the spaces between the positioning mechanism and two lateral surfaces of the strip steel coil are adjustable, and the bundle wire kinking mechanism has simple devices, reliable performance and good stability.

Description

Technical field: [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a binding wire twisting mechanism of a steel coil bundling machine. Background technique: [0002] Existing balers mainly include a base, a trolley, an oil cylinder, a hydraulic motor, a wire feeding and drawing mechanism, a tying shear mechanism, a kink mechanism, and a tying thread. The main function of the twisting mechanism of the baler is to twist the two ends of the tying wire together to prevent the bundled objects from being bundled. The binding wire twisting mechanism of the existing baler is mainly composed of a hydraulic jaw assembly for clamping the two ends of the wire rod, which includes a hydraulic motor, a front jaw, a rear jaw, a jaw shaft, etc., front and rear The jaws are hinged on the jaw shaft, and each has a slope at the rear. The two slopes face each other to form a wedge-shaped space. When the pressure oil of the hydraulic motor p...

Problems solved by technology

The disadvantage of this device design is: because the distance between the clamping jaw of the kink mechanism and the bundled object is too close, it can only be applied to the bundled object with a temperature below 120°C. For hot-rolled objects with a temperature around 700°C Narrow-strip steel coils are not suitable, because the parts are too close to the heat source, it is easy to produce high-temperature radiation annealing, resulting in reduced working life and affecting use
