Steel bar binding machine for construction site

Abstract

The invention relates to the technical field of building construction, and discloses a reinforcing steel bar binding machine for a construction site. A wire winding drum is movably mounted at one end in a machine shell; a wire guiding wheel is fixedly mounted at the top position, between a conveying motor and a torsion motor, in the machine shell; a transmission device is fixedly installed at the position, located at the bottom between the conveying motor and the torsion motor, in the machine shell; a hydraulic hole is formed in the transmission device; the top of the hydraulic hole is movably sleeved with a pressure rod; the bottom end of the hydraulic hole is movably sleeved with a clamping strip; the outer ring of the wire winding drum is fixedly sleeved with an outer gear; a transmission sleeve is movably installed in an installation groove; a limiting shaft is movably installed in the middle of the installation groove; tooth keys meshed with the outer gear are evenly and fixedly installed on the outer ring of the transmission sleeve; and a coil spring is movably connected between the transmission sleeve and a limiting shaft. Through the arrangement of the outer gear, and the transmission sleeve, the transmission device, a pressure rod and other structures are matched to act together, so that the binding quality is improved, and the iron wire cost is saved.

[0002] Rebar is an indispensable material in the construction industry. It is mainly used for concrete pouring to increase its strength. For cross-overlapping rebar, it needs to be bundled to prevent it from falling apart. The most common way is to use manual Bundle the iron wire well, but it is still too slow for large-scale projects or large-area construction, so it is necessary to use a machine to quickly bind the iron wire, so a steel bar binding machine appeared, which uses an internal motor to drive the iron wire. It will also be possible to bend the iron wire and cut off and finally twist the exported iron wire through the design of the structure, but there are some problems with this steel bar binding machine:

[0003] When bundling steel bars, use the reel to feed the wire and push the iron wire out through the motor's conveying effect. When it is bent forward along the guide wire hole and wound in a ring shape, a large ring is formed compared with the steel bar, which will lead to A large number of iron wires are used for coiling, but in fact not all of them act on the steel bar 18 completely. When the torsion motor rotates afterwards, the excess iron wires will only be twisted away, and the iron wires are not fully bound in fact; at the same time , generally 2-3 circles are the most suitable for winding, but due to the error of the shape and position of the steel bar and the error of the strapping machine itself, the wound rings are not all the same, which will lead to the twisting of the iron wire. It does not guarantee a more standard wire twist, while ensuring the utilization rate of the wire
