Description

Automatic binding machine for reinforcing steel bars

Technical Field

The invention belongs to the technical field of constructional engineering, and particularly relates to an automatic binding machine for steel bars.

Background

The steel bar lap joint means that two steel bars have certain overlapping length, are connected by using a binding wire or a binding belt and are suitable for connecting the steel bars with smaller diameters. The reinforcing bar nets in the common concrete are uniformly arranged in longitude and latitude without welding and only need to be fixed by binding wires.

Generally, in the building construction operation process, the bar worker carries out manual ligature through couple, screwdriver etc. and on the one hand the operating efficiency is low, and intensity of labour is high, and on the other hand, the dynamics to the reinforcement varies from person to person, and too big then leads to easily pricking the silk fracture, extravagant pricking the silk, and too little then can not effectively fix the reinforcing bar with exerting oneself.

In the prior art, for example, a chinese patent with a patent number of 200710068072.X provides a hand-held electric reinforcing bar binding machine, which includes a cavity with a handle, a binding wire opening ring is connected to the front end of the cavity, a gear ring matched with the binding wire opening ring is arranged on the binding wire opening ring, an inner ratchet wheel which is arranged on an output shaft of a motor and is matched with the motor in an opposite direction is arranged, the inner ratchet wheel is in transmission fit with one end of a main shaft through a gear pair, a helical gear connected to the other end of the main shaft is in meshing transmission with a helical gear connected to an upper transverse shaft, the upper transverse shaft is in synchronous transmission with the lower transverse shaft, and a winding wheel is connected to the other end of the rotary shaft. The device inherits the action principle of manual operation, replaces manual operation, has improved labor efficiency. However, the above device is inconvenient to use because it is necessary to pull out the binding wire from the binding wire opening and bend and hook the T-shaped pin before use. After the binding wire is tightly bound, the binding wire is cut off by means of the self-hinge force of the binding wire, the cutting position of the binding wire is difficult to control, binding operation failure is easy to cause, and binding wire waste is caused.

and starting the driving speed reducer 70 to enable the driving speed reducer to rotate in a single direction, and setting a rotation stroke, wherein in the rotation stroke, the automatic reinforcing steel bar binding machine 1 finishes the process from wire feeding to wire winding and then to wire gathering. After the driving reducer 70 is started, the driving reducer 70 drives the forward rotation bevel gear 811, and directly acts on the transmission spline bearing 814 through the third coupling 8154 and the first coupler 8111, the transmission spline bearing 814 drives the main driving worm wheel 821 to rotate through the reciprocating driving worm 8142, so that the lower wire stud 31 is driven to rotate through the lower wire driving bevel gear 822 and the lower wire input bevel gear 823, and the wire feeding is completed. Meanwhile, the main driving worm gear 821 drives the ring driving gear 4251 and the top lead screw driving gear 431 to rotate simultaneously through a shaft, the top lead screw 41 retracts to the starting point of the motion track, namely below the wire outlet 311, the wire feeding ring 421 drives the binding wire to move to the end point of the motion track through the second wire hanging column 4211, namely to be close to one side of the wire end wire gathering piece 51, in the process, the first clamping groove 541 is clamped with the first hanging column 531, the second clamping groove 551 is clamped with the second hanging column 532, and the wire end wire gathering piece 52 is far away from the wire end wire gathering piece 51.

After the wire binding is finished, the whole automatic binding machine 1 for the steel bars moves backwards, the taper shank 613 drives the taper head 612 to be recovered under the action of the restoring force of the wire withdrawing spring 615, and the taper shank 613 reversely rotates under the action of the wire withdrawing chute 6132 in the recovery process, so that the rapid wire withdrawing is realized. Meanwhile, the wire binding force is effectively controlled by the limitation of the maximum compressibility of the wire withdrawing spring 615, so that the wire breaking rate of the binding wire is effectively reduced.

The wire binding driving gear 622 is powered by the wire binding driving rod 621, and the wire binding vertebra transmission gear 614 is driven to rotate to perform wire binding. When the preset wire binding force is reached, the wire binding vertebra transmission gear 614 is difficult to rotate and reacts on the wire binding driving gear 622, at the moment, the fixed teeth 6231 are almost stuck, the buffer teeth 6232 compress the buffer spring 6233 under the reaction force, so that the fixed teeth 6231 are separated from the buffer teeth 6232, and the separated buffer teeth 6232 are clamped with the fixed teeth 6231 under the restoring force of the buffer spring 6233.
