Description

Ribbon conveying mechanism for anti-jamming materials

Technical Field

The utility model relates to the technical field of ribbon machines, in particular to a ribbon conveying mechanism capable of preventing materials from being blocked.

Background

The strapping machine is a mechanical device for replacing manual strapping, and generally comprises a strapping transfer mechanism which functions to separate and guide out the strapping (typically nylon strapping) thereof one by one, thereby facilitating strapping and cutting.

The authority bulletin number CN213384876U discloses a ribbon conveying mechanism of a ribbon machine, and particularly discloses a feeding mechanism for conveying a ribbon to a pushing mechanism, the pushing mechanism for pushing the ribbons separately one by one and a guiding mechanism for guiding out the pushed ribbons; the pushing mechanism comprises a pushing cylinder, a pushing seat, a guide rail, a pushing rod and a pushing block; the pushing seat is fixed on an output shaft of the pushing cylinder and can be arranged on the guide rail in a front-back sliding manner; a pushing groove extending along the front-back direction is arranged on one side edge of the pushing block, and the pushing groove is used for placing a binding belt; the pushing rod is fixed with one side of the pushing seat and is positioned on the pushing groove; the front end of the pushing rod is L-shaped and used for limiting the ribbon, and the pushing rod is used for pushing the ribbon. The pushing block is also provided with an optical fiber sensor for detecting the in-place binding belt.

However, there is room for improvement in the above-described band conveying mechanism, such as: when the feeding mechanism sends the ribbon to the pushing groove of the pushing mechanism, the head of the ribbon can be correspondingly clamped into the L-shaped front end of the pushing rod. However, in the use process of the machine, due to vibration or other objective reasons of the machine, the situation that the head of the ribbon on the pushing groove is not matched and attached with the L-shaped front end of the pushing rod before being pushed can possibly occur, and even the ribbon is separated from the detection range of the optical fiber sensor; if the head of the ribbon is not matched and attached with the L-shaped front end of the pushing rod (namely, the loosening condition occurs), when the pushing rod pushes the ribbon, the ribbon can possibly incline due to the action of pushing force, so that the ribbon cannot be accurately sent to a preset position of the material guiding mechanism, namely, the follow-up material blocking (also called stacking) is easy to cause, and then the ribbon needs to be dredged; if the ribbon breaks away from the detection range of the optical fiber sensor before pushing, the optical fiber sensor can send out the model that no ribbon exists on the pushing groove to the control center, so that the feeding mechanism can continuously send in new ribbon on the pushing groove, and then at least two ribbons exist on the pushing groove at the same time, and finally the two ribbons can not be accurately sent to the preset position of the guide mechanism, thus the follow-up clamping is caused, and then the ribbon needs to be dredged.

Accordingly, improvements in the art are needed.
