Bundling device

Abstract

The invention relates to a rod section bar bundling device for bundling steel wires by rubber tapes. The rod section bar bundling device comprises a machine frame, wherein an upper arm and a lower arm are arranged on the machine frame; an air cylinder I is arranged on the upper arm and is suitable for moving left and right relative to the upper arm, a piston I and a connecting rod I in the air cylinder I are suitable for vertically moving, and a telescopic nail box is arranged at the bottom end of the connecting rod I; a table board for placing a steel bundle is arranged on the lower arm in a left-right sliding fit manner, an air cylinder II is fixedly arranged at the bottom of the lower arm, a piston II and a connecting rod II at the top of the piston II are arranged in the air cylinder II, a pair of grooves is formed in the top surface of the connecting rod II, and the grooves are suitable for allowing nails to penetrate through and tightly grasp a rubber tape for bundling the steel bundle when the connecting rod I and the connecting rod II are aligned and pressed; a pressing block which is suitable for moving relative to the connecting rod II and is used for clamping ends of the rubber tape is arranged on the right side of the connecting rod II. For the rod section bar bundling device, during the process of bundling, a virtual-wire phenomenon cannot occur, and once bundling is finished, the steel bundle is not easy to loosen due to displacement of the steel wires.

Description

technical field [0001] The invention relates to a rod profile bundling device for bundling steel materials with rubber belts, which is used for bundling and packaging steel materials. Background technique [0002] Most of the bar and profile bundling devices in the prior art use iron wire rods to pack steel bundles. Since this kind of wire rods have a relatively large minimum bending radius, when bundling steel bundles with small diameters , it will cause the wire rod to be stuck very late and cannot continue to be tightened, resulting in the phenomenon of virtual wires, which will cause the phenomenon of loose binding; However, since the shapes of steel bundles are different, and since the wire rod and steel are made of the same material, the friction coefficient between each other is small, and the steel bundle after tightening will also appear in the hoisting process due to the displacement of one of the steel rods. A loose bundle appears. Contents of the inventi...

Problems solved by technology

[0002] Most of the bar and profile bundling devices in the prior art use iron wire rods to pack the steel bundles. Bending radius, when bundling steel bundles with small bundle diameters, the wire rods will be stuck very late and cannot continue to be tightened, resulting in virtual wires and loose bundles; on the other hand, due to the iron wire rods The flexibility of the wire rod is not high, and it needs to use a large force to tighten it. However, because the shapes of the steel bundles are different, and because the wire rod and the steel are made of the same material, the friction coefficient between them is small, and the steel bundle after tightening During the hoisting process, there will be loose bundles due to the displacement of one of the steel bars
