The arrangement of the conveying device 3 can realize the clamping and conveying of the packaging bag, and the packaging bag at the bag feeding mechanism 1 is clamped and conveyed to the next station, and this embodiment drives the clamping mechanism 32 to transport the packaging bag to the feeding mechanism 2 for feeding by the driving mechanism 31, thereby changing the existing problems of complicated processing procedures and movements at the same station, further improving the packaging efficiency, and the efficiency can be as high as 3600 pieces / h, and when in use, the packaging bags are clamped one by one to the clamping opening of the clamping mechanism 32 through the action of the bag feeding mechanism 1, so that the bag feeding is accurate, and the phenomenon of the packaging bag falling will not occur, and the uniformity of the bag opening is guaranteed, and the packaging quality is improved, which has substantial characteristics and progress.

[0031] Example 2

[0032] This embodiment discloses a bag feeding packaging machine, wherein a conveying device 3 is arranged between a bag feeding mechanism 1 and a feeding mechanism 2, and the conveying device 3 comprises a driving mechanism 31 and a clamping mechanism 32, wherein the driving mechanism 31 drives the clamping mechanism 32 to rotate along the material transportation direction, and at the same time, the driving mechanism 31 can drive the bag feeding mechanism 1 to automatically feed bags, and the driving mechanism 31 can drive the feeding mechanism 2 to reciprocate along the vertical direction. The clamping mechanism 32 is arranged in a circular array on the driving mechanism 31 and is located between the bag feeding mechanism 1 and the feeding mechanism 2, and is used to clamp and transport the packaging bags on the bag feeding mechanism 1 to the feeding mechanism 2. Driven by the driving mechanism 31, the clamping mechanism 32 reciprocates between the bag loading mechanism 1 and the feeding mechanism 2 along the rotation axis of the driving mechanism 31. In this embodiment, the clamping mechanism 32 reciprocates between the bag loading mechanism 1 and the feeding mechanism 2 along the rotation axis of the driving mechanism 31 under the drive of the driving mechanism 31. The packaging bag is clamped and conveyed to the feeding mechanism 2. During the conveying process, the packaging can be kept from tilting, falling or hanging on one side.

[0033] The packaging bag is clamped by the clamping mechanism 32 at the bag loading mechanism 1 station and then transported to the feeding mechanism 2. When the feeding mechanism 2 enters the next action to introduce the material into the packaging belt, after the packaging belt of the bag loading mechanism 1 is supported and transported away, the next packaging belt can be immediately separated at this station and wait for clamping and transportation. After the feeding mechanism 2 completes the action and is transported away, the clamping mechanism 32 can also quickly clamp and transport the next packaging bag from the bag loading mechanism 1 to the feeding mechanism 2, which can effectively improve the packaging efficiency.

[0034] Example 3

[0035] This embodiment discloses a bag feeding packaging machine, wherein a conveying device 3 is arranged between a bag feeding mechanism 1 and a feeding mechanism 2, and the conveying device 3 comprises a driving mechanism 31 and a clamping mechanism 32, wherein the driving mechanism 31 drives the clamping mechanism 32 to rotate along the material transportation direction, and at the same time, the driving mechanism 31 can drive the bag feeding mechanism 1 to automatically feed bags, and the driving mechanism 31 can drive the feeding mechanism 2 to reciprocate along the vertical direction. The clamping mechanism 32 is arranged in a circular array on the driving mechanism 31 and is located between the bag feeding mechanism 1 and the feeding mechanism 2, and is used to clamp and transport the packaging bags on the bag feeding mechanism 1 to the feeding mechanism 2.

[0036] On the basis of the above embodiment, the bag-feeding packaging machine further includes a bag-opening mechanism 4, which is arranged on the circumferential side of the rotation direction of the clamping mechanism 32, and is used to open the packaging bag transported to the bag-opening mechanism 4; the bag-opening mechanism 4 is driven by the driving mechanism 31 to reciprocate in the vertical direction to fully open the packaging bag. In this embodiment, the bag-opening mechanism 4 of the bag-feeding packaging machine is arranged between the bag-loading mechanism 1 and the feeding mechanism 2, and is arranged along the circumference of the driving mechanism 31, and is used to open the packaging bag conveyed by the bag-loading mechanism 1. Before the material is loaded into the packaging bag, it must pass through the bag-opening mechanism 4 and extend into the packaging bag to fully open it. The clamping mechanism 32 is arranged directly below the bag-opening mechanism, which can effectively shorten the telescopic distance of the bag-opening mechanism 4 and improve the bag-opening efficiency. In addition, the feeding mechanism 2 is pre-positioned under the bag-opening mechanism 4, which can effectively avoid damage to the packaging bag when the material enters the packaging bag.

Further, the structure of the first bag opening component 43 and the second bag opening component 44 are consistent. The first bag opening component 43 includes an optical axis with gears at one end, and a vacuum suction cup component is fixedly connected to the other end of the optical axis; at the same time, a cylinder for providing lifting and lowering movement and a slidable ejector are fixedly arranged on the vacuum suction cup component; wherein the cylinder can drive the ejector to move back and forth along the vertical direction. Specifically, when the clamping mechanism 32 delivers the packaging tape to the bag opening mechanism 4, the vacuum suction cup components respectively suck the front and rear parts of the packaging bag. At this time, the servo motor driver 42 starts to drive the first bag opening component 43 and the second bag opening component 44 to move relative to each other, and open the packaging tape. While opening, it cooperates with the retraction of the clamping mechanism 32 to open it quickly. Then the cylinder moves to push the ejector into the packaging bag, and the wrinkled parts on both sides of the packaging bag are pushed open by the ejector. When the blowing component 45 stops blowing, the packaging bag can still be opened when the first bag opening component 43 and the second bag opening component 44 are moved apart, ensuring that the materials on the subsequent feeding mechanism 2 can enter the packaging bag smoothly, which can effectively improve the packaging efficiency.

[0038] Based on the above embodiment, the ejector member includes an ejector base for support, on which an ejector rod is adjustably provided; a push piece is adjustably provided at the end of the ejector rod; and a sensor is also provided on the ejector base.
