Disclosure of Invention

The invention aims to provide a bag opening mechanism which can effectively improve the working efficiency, save the labor, and is simple to operate and convenient to use.

In order to achieve the purpose, the invention adopts the following technical scheme:

a bag opening mechanism comprises a mounting seat, a left support and a right support, wherein the left support and the right support are L-shaped and are oppositely arranged on two sides of the mounting seat, the tail parts of the left support and the right support are connected through springs, and the middle parts of the left support and the right support are rotatably connected with the mounting seat through connecting rod assemblies;

the end parts of the left support and the right support are respectively provided with a L-shaped left clamping arm and a L-shaped right clamping arm, a transverse plate is arranged between the left support and the right support, the left clamping arm, the right clamping arm and the transverse plate form a box body structure with two open ends in a reset state, the left support and the right support can enable the left clamping arm and the right clamping arm to be opened outwards under the action of a power device, and the left clamping arm and the right clamping arm can be reset under the action of a spring.

As a further improvement of the above technical solution:

the transverse plate is rotatably connected with the connecting rod assembly through the middle block, and the middle block can drive the transverse plate to move back and forth under the action of the connecting rod assembly.

The connecting rod assembly comprises a plurality of long first connecting rods and a bent second connecting rod, and the left support and the right support are connected with each other through the first connecting rods and the second connecting rods to realize left and right opening and closing of the left support and the right support.

The cross-sectional area of the middle block is approximately L type, one end of the middle block is rotatably connected with the connecting rod assembly through a rotating shaft, the middle block is driven by the connecting rod assembly to move back and forth, and the other end of the middle block is used for fixing the transverse plate.

According to the technical scheme, the bag opening mechanism is simple in structure, simple to operate and convenient to use, and objects can accurately fall into the bag body from the opening direction of the box body conveniently, so that the working efficiency can be effectively improved, and the manpower is saved.
