Description

Technical Field

[0001] This utility model relates to the field of moxa stick processing technology, specifically to a pre-made moxa stick bag film packaging machine. Background Technology

[0002] Moxa sticks have a wide range of applications, and during transportation and storage, they require packaging to ensure their integrity, prevent moisture and mold, and maintain the quality of the moxa wool. Traditional packaging methods rely on manual labor, which is inefficient. Therefore, automated packaging equipment has been designed. However, existing automated packaging equipment is cumbersome, often using film-coating or pre-arranging and positioning before packaging. For example, Chinese invention patent CN110123626B, entitled "Automated Moxa Stick Cutting and Packaging Equipment," describes a method where each moxa stick is inserted into a corresponding slot. This requires specialized positioning equipment, and the insertion position of each moxa stick must be accurate. This packaging method is cumbersome, inefficient, and prone to errors, leading to shortages, omissions, or uneven packaging. Therefore, a packaging machine with a simple process and high efficiency is needed. Utility Model Content

[0040] Working process: Moxa sticks are placed one by one on the feeding conveyor belt 1 in the front-to-back direction. As it moves to the bottom of the pressure plate, it is shaped for the first time. A set of baffles 401 in the feeding synchronous belt 4 stops corresponding to the material-aligning cylinder. Then, the material-aligning cylinder pushes a predetermined number of moxa sticks between the baffles 401. Then, it waits for the moxa sticks to be pushed again, forming two layers of moxa sticks between the same baffles 401. The feeding synchronous belt 4 moves to the right until the moxa sticks correspond to the unloading cylinder 402. The pre-made bag lifting mechanism 11 lifts the pre-made bag 1101 until the top pre-made bag can be sucked by the bag-retrieving suction cup 1001. After the bag-retrieving suction cup 1001 picks up a pre-made bag 1101, it is driven by the bag feeding cylinder to place the pre-made bag 1101 on the support frame 9. At the same time, the suction cup 7 on the bag support and the support frame 9 are also in operation. Between the suction cups 8 under the bag, the sensor senses a pre-made bag on the support frame 9. The pre-made bag is then sucked up by the bag-making cylinder 502. After being sucked up, the two are separated by the bag-making cylinder 502, causing the pre-made bag 1101 to open. The opening and closing cylinder 67 extends and pushes the gripper seat 64 to rotate, which eventually causes the front ends of the two grippers 65 to move relative to each other. Then, the moving mechanism drives the bag-making cylinder 502, which in turn drives the pre-made bag 1101 to move the supporting structure, and finally puts the pre-made bag 1101 on the outside of the two grippers 65. Then, the movable end of the opening and closing cylinder 67 retracts, and the gripper seat 64 returns to its original position under the action of the tension spring 66. The front ends of the two grippers 65 separate and open the pre-made bag 1101 to the left and right. Air is sprayed into the opening of the pre-made bag 1101 as needed.

[0041] The rotary motor 62 is started, causing the upper support structure to rotate to correspond with the pushing cylinder 402. The pushing cylinder 402 is activated, pushing the moxa stick connected to the pre-made bag 1101 into the discharge conveyor belt 15. As it moves to the right, the remaining portion of the pre-made bag 1101 is located between the first electric heating cutter 1203 and the second electric heating cutter 1204. The discharge conveyor belt 15 stops, the film cutting cylinder 1201 extends, and the first electric heating cutter 1203 and the second electric heating cutter 1204 close to cut off the remaining portion of the pre-made bag. The bag is separated and initially sealed; the waste-clamping cylinder 1801 extends, the rotary cylinder 1802 rotates to adjust the angle, the waste-clamping claw 1803 clamps the cut-off amount, then the movable end of the waste-clamping cylinder 1801 retracts, and then the waste-clamping claw 1803 throws the remaining amount into the recycling box; the suction cup negative pressure gauge 13 monitors the status of each suction cup, and is used to monitor whether the pre-made bag supply and bagging are smooth; the temperature control display 14 ensures that the temperature of the first electric heating cutter 1203 and the second electric heating cutter 1204 is conducive to cutting and separation.
