[0059] The embodiments of the present application will be further described below with reference to the drawings:

[0060] As shown in the drawings, a transmission mechanism of a packaging machine comprises a frame, a first guide shaft 1, a second guide shaft 2, a mounting seat 3 between the first guide shaft 1 and the second guide shaft 2, a transmission assembly and a bag clamping assembly connected to the first guide shaft 1 and the second guide shaft 2 respectively, a sliding assembly fixedly installed on the mounting seat 3 and a bumping assembly slidingly installed on the mounting seat 3, the bag clamping assembly being slidingly installed on the sliding assembly, the first guide shaft 1 being connected to the bag clamping assembly in linkage, the second guide shaft 2 being connected to the bumping assembly in linkage, and the bag clamping assembly and the bumping assembly being in contact and cooperation.

[0061] The first guide shaft 1 and the second guide shaft 2 can both be lifted and rotated under the drive of the transmission assembly.

[0062] The first guide shaft 1 can drive the bag clamping assembly to slide left and right on the sliding assembly when the first guide shaft 1 rotates.

[0063] The second guide shaft 2 can drive the bag clamping assembly to open and close through the bumping assembly when the second guide shaft 2 rotates. The present technical solution drives the first guide shaft and the second guide shaft to realize two actions of lifting and rotating. When the first guide shaft and the second guide shaft are lifted at the same time, the first guide shaft and the second guide shaft rotate again. The rotation of the first guide shaft can drive the bag clamping assembly to slide linearly along the sliding assembly, so that the bag clamping assembly moves from above the sub-clamping mechanism to above the bag storage assembly. When the first guide shaft and the second guide shaft are lowered at the same time, the rotation of the second guide shaft drives the bumping assembly to move, so that the bag clamping assembly is closed and clamps the packaging bag. Then the first guide shaft drives the bag clamping assembly to slide linearly through rotation. In the sliding process, the second guide shaft rotates and drives the bag clamping assembly to open the folded edge of the packaging bag through the bumping assembly, so that the sub-clamping mechanism can more easily clamp the folded edge of the packaging bag. When the packaging bag is transported to above the sub-clamping mechanism, the sub-clamping mechanism clamps the four edges of the folded edge of the packaging bag, and then the bag clamping assembly completely separates from the folded edge of the packaging bag. Then the above process is repeated to complete the above actions in a cycle, which has the advantages of good continuity of actions and good stability of work.

[0064] The bag clamping assembly comprises a cover plate 4 and a suction cup base 5, the first suction cup support 6 and the second suction cup support 7 are installed on both sides of the suction cup base 5, a plurality of position-adjustable first suction cup pieces 8 are installed on the first suction cup support 6, a plurality of position-adjustable second suction cup pieces 9 are installed on the second suction cup support 7, the first suction cup pieces 8 and the second suction cup pieces 9 are oppositely arranged, the suction cup base 5 is provided with linkage components for driving the first suction cup support 6 and the second suction cup support 7 to move synchronously towards or away from each other, the contact component is in contact with the linkage components, the positions of the first suction cup pieces and the second suction cup pieces are adjustable, and the bag clamping assembly can adapt to packaging bags of various sizes.

[0065] The entire detailed action flow of the bag clamping assembly is as follows:

[0066] Step 1: After the first guide shaft and the second guide shaft rise simultaneously, the two rotate, the rotation of the first guide shaft can drive the bag clamping assembly to move linearly along the sliding assembly, so that the bag clamping assembly moves from above the sub-clamping mechanism to above the bag storage assembly;

[0067] Step 2: After the first guide shaft and the second guide shaft descend simultaneously, the rotation of the second guide shaft drives the contact component to move, so that the bag clamping assembly is closed and clamps the packaging bag;

[0068] Step 3: The first guide shaft drives the bag clamping assembly to move linearly by rotating, so that the packaging bag is transported to above the sub-clamping mechanism, in the movement process, the second guide shaft rotates and drives the first suction cup support 6 and the second suction cup support to move a proper distance to the two sides through the contact component to open the gusset packaging bag, so that the sub-clamping mechanism can clamp the gusset packaging bag more easily, but the first suction cup piece and the second suction cup piece are still in the state of vacuum adsorption on the packaging bag, after reaching above the sub-clamping mechanism, the sub-clamping mechanism clamps the four edges of the gusset packaging bag, then the first suction cup piece and the second suction cup piece stop vacuum adsorption, and the bag clamping assembly completely releases the packaging bag.

[0069] The above three steps are cyclically performed, and at the end of step three, the bag clamping assembly is separated from the packaging bag before the first guide shaft and the second guide shaft rise simultaneously, so as to prevent the packaging bag from being hooked.

[0070] In addition, the rotation of the first guide shaft and the second guide shaft in step 1 can be performed synchronously or in steps.

[0071] When the rotation is performed synchronously, the first roller of the bag clamping assembly is always in the high position of the contact block during the linear movement, and the bag clamping assembly is in the open state;

[0072] When the rotation is performed in steps, the bag clamping assembly is first closed during the linear movement, and then opened after the bag clamping assembly is in place; there is an exception, when the stroke of the high position of the contact block is long enough, the bag clamping assembly is always in the open state during the linear movement.

[0073] Similarly, the rotation of the first guide shaft and the second guide shaft in step 3 can be synchronous or step by step. When the rotation is synchronous, the bag clamping assembly will always be in a closed state during the linear motion, and the first suction disc and the second suction disc will be in a state of vacuum adsorbing the packaging bag. When the rotation is step by step, the bag clamping assembly will be opened during the linear motion, and then the sub-clamping mechanism will clamp the four edges of the packaging bag, and then the first suction disc and the second suction disc will stop vacuum adsorbing the packaging bag.

[0079] In addition, the elastic members on the first optical axis and the second optical axis provide pre-tightening force for the reset of the first suction disc support and the second suction disc support, so that the first suction disc support and the second suction disc support move towards each other, and the first rack and the second rack drive the gear to reverse.
