Technical Field
The utility model relates to a belt feeding and retracting structure of a binding machine.
Background

SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a belt feeding and retracting structure of a strapping machine, which can enable a strapping belt to be partially wrapped on a driving wheel in the moving process, and increase the friction force between the strapping belt wrapped on the driving wheel and the driving wheel by combining the tension force of the strapping belt during tightening with the tension force of the strapping belt during retracting, so that the tightening force of the strapping belt is enhanced.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model relates to a belt feeding and retracting structure of a strapping machine, which is characterized in that a driving wheel and a driven wheel form a strap feeding and retracting structure, and the guide belt structure changes the moving direction of the strapping belt; the driven wheel is close to the driving wheel in parallel, the driven wheel pushes the driven wheel to the driving wheel through the pressing structure, so that certain pressure exists between the driving wheel and the driven wheel, when the strapping tape passes through the tangent position of the driving wheel and the driven wheel, the motor rotates to drive the driving wheel to rotate, and the strapping tape performs corresponding tape feeding and withdrawing actions under the coordination of the driven wheel; the strapping tape is wound on the surface of the driving wheel due to the action of the conduction band structure, the friction force of the driving wheel to the strapping tape is increased when the strapping tape is wound, and the strapping tape is wound by a strong pulling force, so that the object is bundled more tightly, and the tightness of the bundling can be changed by adjusting the compression structure of the driven wheel.
The strapping tape can be partially wrapped on the driving wheel in the moving process.
The pressing structure consists of a pressing knob, a nut, a spring and a pressing belt seat.
The driven wheel is provided with a coded disc, an optical coupler is arranged on the edge of the coded disc, and the condition of belt feeding or belt retracting is detected through the optical coupler. The upper structure of the driving wheel is an arc-shaped guide belt structure, so that a certain angle is formed between the strap outlet of the strapping tape and the tangent point of the driving wheel and the driven wheel, and the strapping tape is tightly attached to the driving wheel in the moving process.
The utility model has the beneficial effects that: through changing the moving direction of the strapping tape, the friction force between the driving wheel and the strapping tape is increased during the tape collection, the tightening force of the tape collection is enhanced, and the strapped object is more compact.
