Description

The rubber belt 13 is made of neoprene or hydrogenated nitrile rubber and cord, has high strength, and can be used for binding steel bundles instead of common wire rods.

The working process of the bar profile bundling device comprises the following steps:

(1) a third motor 27 drives the table top 19 to move rightwards, the steel bundle 18 is placed on the table top 19, and the position needing to be bundled is aligned with a second U-shaped through hole 191 in the table top 19;

(2) the second motor 14 works to drive the guide wheel 16 and the first pulley 17 to rotate, and the rubber belt 13 on the wire coil 11 vertically moves downwards through the third pulley 44 and the second pulley 30;

(3) the motor IV 41 works to drive the pressing block 39 to move rightwards, so that a gap for accommodating a rubber belt is formed between the pressing block and the connecting rod II 26, meanwhile, the motor I2 works to drive the cylinder I4 to move leftwards and rightwards, so that the rubber belt is aligned with the gap, when the rubber belt reaches a position between the pressing block and the connecting rod II, the motor IV rotates reversely, and the pressing block moves leftwards and is pressed with the connecting rod II, so that the end part of the rubber belt is clamped;

(4) the first cylinder 4 works to enable the first connecting rod 8 to move upwards, the second cylinder 24 works to enable the second connecting rod 26 to move downwards below the table top 19, meanwhile, the third motor 27 rotates reversely to drive the table top 19 to move leftwards, so that the steel bundle 18 moves to the left side from the right of the first cylinder 4 and the second cylinder 24, when the steel bundle 18 passes through the space between the first cylinder 4 and the second cylinder 24, the first connecting rod 8 moves downwards, the second connecting rod 26 moves upwards, the speed of the first connecting rod and the second connecting rod is controlled, meanwhile, the first connecting rod is adjusted to be right opposite to the second connecting rod through the first motor 2, when the lower end of the first connecting rod and the upper end of the second connecting rod are just positioned in the right middle of the steel bundle to converge, the rubber belt 13 wraps the steel bundle from the middle of the left side of the steel bundle to the middle; in the process, the second motor 14 controls the downward moving speed of the rubber belt, so that the rubber belt is synchronous with the action and is always in a tensioning state in the whole process.

(5) When the first connecting rod 8 and the second connecting rod 24 are opposite and tightly pressed, the nail box 33 moves upwards relative to the first connecting rod 8, nails in the nail box penetrate through the two layers of rubber belts due to the pressure of the pressing block 34, deform and bite the rubber belts as required under the action of the groove 261, and meanwhile, the blade 38 cuts off the rubber belts.

When the rubber belt 13 is used for bundling the steel bundle, the steel bundle is wrapped from the middle part of the left side of the steel bundle to the middle part of the right side of the steel bundle along the circumferential directions of the two sides, stress is uniform in the bundling process of the steel bundle, due to the fact that the rubber belt is good in flexibility and smaller in bending radius than a wire rod, the phenomenon of virtual wires cannot occur in the bundling process, meanwhile, due to the fact that the rubber belt is large in friction coefficient between the rubber and the steel bundle and elastic, the steel displacement phenomenon and the bundle loosening phenomenon cannot occur easily after the steel bundle is bundled.

It should be understood that the above examples are only for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And such obvious variations or modifications which fall within the spirit of the invention are intended to be covered by the scope of the present invention.
