[0002] The secondary bagging packaging equipment, also known as the secondary packaging equipment, generally refers to the equipment that completes the packaging process in indirect contact with the object to be packaged. It is commonly seen in industries such as food, medicine, cosmetics, and chemicals. Through a series of conveyors and packaging machinery, small bag products are automatically loaded into large bags in a certain arrangement and quantity, and then sealed and output. With the continuous upgrading of the consumer market and the increasing requirements of consumers for product packaging, the demand for secondary bagging packaging equipment in the market will continue to grow. Especially in industries such as food, medicine, and cosmetics, the application of secondary packaging equipment will be more extensive.

[0003] Chinese Patent CN216734878U discloses a secondary bagging mechanism for bagged powder, including a bag body placement mechanism, a bag body opening mechanism, and a discharging mechanism. Among them, a bag body opening mechanism is arranged on one side of the bag body placement mechanism, a first sliding component is arranged on the bag body placement mechanism, a secondary packaging bag with an opened bag mouth is clamped inside the bag body opening mechanism, and a lifting component for lifting the powder bag body is arranged inside the bag body opening mechanism and the lifting component gives way to the bag body placement mechanism; a discharging mechanism is arranged on one side of the bag body opening mechanism; it is convenient to perform secondary packaging on the powder packaging through an automatic packaging method, so the packaging efficiency is relatively high and the labor intensity of workers is relatively low, but there are still the following deficiencies.

[0004] When the existing secondary packaging equipment performs secondary bagging, although it can successfully open the bag mouth, during the process of loading materials into the packaging bag, the materials are extremely easy to adhere to the edge of the bag mouth and cause the bag mouth to fold. This phenomenon seriously affects the subsequent processing process. Therefore, the inventor proposes a reciprocating secondary bagging packaging equipment and a packaging method for powder bagging to solve the above problems. Summary of the Invention

[0005] To solve the above problems, a reciprocating secondary bagging packaging device and a packaging method for powder bagging are provided. By symmetrically arranging a plurality of second cylinders at the bottom of the third fixing frame, fixing a fourth fixing frame at the output end of the second cylinder, and then fixing the third cylinder inside the third cylinder, the third cylinder drives the suction cup to move horizontally through the fixing plate. After the suction cup contacts the surface of the packaging bag, the third cylinder opens the packaging bag opening through the fixing plate and the suction cup. Then, the second cylinder drives the third cylinder to move upward through the fourth fixing frame, so that the packaging bag can be sleeved outside the output end of the feeding leak and clamped, realizing that the packaging bag opening can be fully opened during the bagging process of the packaging device, and solving the problem that the packaging bag opening cannot be fully opened, thus affecting the bagging efficiency.

[0006] To solve the problems of the prior art, the present invention provides a reciprocating secondary bagging packaging device, including a frame.

[0010] As a technical solution of the present invention, two groups of slide rails are symmetrically and fixedly installed at both ends of the inner top end of the machine frame near the third fixing bracket and the plastic sealing device. A slider is slidably installed on the outside of the slide rail. A third flange is fixedly installed on the side surface of one end of the slider.

[0014] As a technical solution of the present invention, a feeding table for support is provided at the center inside the frame, and the feeding table is directly below the feeding leak. At the other end inside the frame, there is a finished product output device capable of outputting the packaged items. One end of the top of the frame is fixed with a stepping feeding device for conveying materials, so that the stepping feeding device conveys the raw materials to be secondary packaged into the feeding leak, so that the raw materials to be packaged are guided through the feeding leak into the packaging bag.

[0015] The present invention also provides a packaging method for powder bagging of a reciprocating secondary bagging packaging device, including the following steps of a reciprocating secondary bagging packaging device:

[0016] S1. By placing the packaging bag on the upper end face of the packaging bag feeding device, the packaging bag feeding device drives the packaging bag to move intermittently. When the packaging bag moves to the end of the packaging bag feeding device, the second telescopic component drives the swing arm to rotate along the first fixed rod through the first flange, and then the first rotating driving part drives the first telescopic component to rotate and adjust the angle. Then, the second rotating driving part drives the first cylinder to rotate and adjust the angle, so that the first cylinder drives the bag clamping device to extend forward, so that the bag clamping device clamps the packaging bag and moves the packaging bag to the bottom of the feeding leak;

[0017] S2. The second cylinder drives the fourth fixed frame to move downward, so that the fourth fixed frame drives the third cylinder to move downward. Then, the third cylinder drives the suction cup to move downward through the fixed plate. When the suction cup is on both sides of the packaging bag, the third cylinder drives the working end of the suction cup to contact the surface of the packaging bag through the fixed plate, so that the suction cup adsorbs the packaging bag, and the third cylinder drives the suction cup to retract through the fixed plate, so as to open the packaging bag. Then, the second cylinder drives the third cylinder through the fourth fixed frame, so that the third cylinder drives the packaging bag to move upward through the fixed plate and the suction cup, so that the packaging bag is sleeved outside the output end of the feeding leak. At the same time, a stepping feeding device is arranged at the top of the frame to drive the materials to be secondary packaged to be conveyed into the feeding leak one by one, and conveyed into the packaging bag through the feeding leak;

[0018] S3. Drive the slider to slide horizontally along the slide rail through the fifth telescopic component. After the fifth telescopic component drives the slider to move to both ends of the third fixing frame, the third telescopic component arranged inside the second flange drives the telescopic adjustment frame to adjust the angle through the fifth fixing frame, so that the telescopic adjustment frame drives the clamping plate to adjust the angle through the third mounting frame and the movable frame, so that the clamping plates are on both sides of the packaging bag. Then, the fourth telescopic component arranged at the top of one side of the third mounting frame drives the movable frame to rotate, so that the fourth telescopic component drives the clamping plates to approach each other through the movable frame, so as to clamp the packaged packaging bag. Then, drive the slider to move along the slide rail through the fifth telescopic component, so that the packaged packaging bag moves to the bottom of the plastic sealing device. When the telescopic adjustment frame contracts, at the same time, drive the top end of the packaging bag to enter the inside of the two plastic sealing clamp blocks through the cooperation of the third mounting frame, the movable frame and the clamping plate, so that the plastic sealing clamp blocks seal the packaging bag and place it on the upper end face of the finished product output device, so that the finished product output device outputs the finished product after packaging.

[0020] In this application, a number of second cylinders are symmetrically arranged at the bottom of the third fixing frame, and a fourth fixing frame is fixed at the output end of the second cylinder. Then, the third cylinder is fixed inside the third cylinder, so that the third cylinder drives the suction cup to move horizontally through the fixing plate. After the suction cup contacts the surface of the packaging bag, the third cylinder opens the packaging bag opening through the fixing plate and the suction cup. Then, the second cylinder drives the third cylinder to move upward through the fourth fixing frame, so that the packaging bag can be sleeved outside the output end of the feeding funnel and clamped, realizing that the packaging bag opening can be completely opened during the bagging process of the packaging equipment, and solving the problem that the packaging bag opening cannot be completely opened, thus affecting the bagging efficiency.
