Knotting mechanism for strapping machine and knotting method

Abstract

The invention relates to a knotting mechanism for a strapping machine. The knotting mechanism comprises a fixed seat, wherein a cam-shaped column body is arranged at one end of the fixed seat; a rotatable eagle nozzle used for knotting is arranged on the cam-shaped column body; a rotating shaft of the eagle nozzle penetrates through the fixed seat to be connected with a one-way bearing through a connecting pin; the tail part of the eagle nozzle is provided with a positioning sliding sleeve used for rotating around the cam-shaped column body to drive the eagle nozzle to open and close when theeagle nozzle rotates; a driving assembly which matches with the one-way bearing and is used for driving the one-way bearing to rotate in one direction to drive the eagle nozzle to rotate is arranged below the fixed seat; and the other end of the fixed seat is connected with a reset driving block used for driving the eagle nozzle to reset through a pin shaft. Compared with the prior art, when the knotting mechanism rotates in the forward direction, the one-way bearing synchronously rotates to drive the eagle nozzle to rotate to carry out knotting action; and when a gear seat rotates reversely,the eagle nozzle can be quickly reset under the action of the reset driving block and a reset spring, so that the eagle nozzle returns to positive position after each knotting is guaranteed, and the mechanism is simple and convenient.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of strapping machines, in particular to a knotting mechanism for a strapping machine and a knotting method. Background technique [0002] The strapping machine is a machine that bundles packages with strapping straps to complete the strapping operation. In the strapping machine, a knotter is generally used to tie the straps. The existing knotter generally includes an olecranon for knotting and a drive mechanism for driving the olecranon to rotate. The drive mechanism drives the olecranon to perform 360° During the rotation, the olecranon will automatically open and close to tie the straps. However, in existing knotters, when the drive mechanism drives the olecranon to rotate, the olecranon rotates with the drive mechanism, and when the drive mechanism resets, the olecranon also resets with the drive mechanism, so that during the drive and reset process, Due to errors during the stroke...

Problems solved by technology

However, in existing knotters, when the drive mechanism drives the olecranon to rotate, the olecranon rotates with the drive mechanism, and when the drive mechanism resets, the olecranon also resets with the drive mechanism, so that during the drive and reset process, Due to errors during the stroke, the olecranon cannot fully return to its normal position, and the olecranon may remain open for a long time, which is convenient for the next knotting action
