[0011] Figure 2 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figures 1-2 As shown, a sealing device includes a frame 1, a sealing machine 2, and a power supply 3. The power supply 3 is electrically connected to the sealing machine 2. It also includes a bag clamping mechanism 4, a rodless cylinder 5, and a first air valve 6. The first air valve 6 and the rodless cylinder 5 are connected via an air pipe. The rodless cylinder 5 includes a slider, and the first air valve 6 controls the slider's movement. The slider is connected to the sealing machine 2 to drive the sealing machine 2 to move horizontally. The bag clamping mechanism 4 includes two telescopic cylinders 41, an upper clamping rod 42, a lower clamping rod 43, and a second air valve 44. The second air valve 44 is connected to the telescopic cylinders 41 via an air pipe and controls the extension and retraction of the piston rod 411 of the telescopic cylinders 41. The lower clamping rod 43 is connected at both ends to the cylinder body of the telescopic cylinder 41, and the upper clamping rod 42 is connected at both ends to the piston rod 411 of the telescopic cylinder 41. The connection configuration of the upper clamping rod 42, lower clamping rod 43, and telescopic cylinder 41 is as follows: Figure 2 As shown, specifically, the lower clamping rod 43 has first through holes 411 at both ends that are sleeved on the piston rod 411, and two countersunk holes 432 on both sides of the first through holes 411. Bolts pass through the countersunk holes 432 to connect the lower clamping rod 43 to the telescopic cylinder 41. The bottom surface of the lower clamping rod 43 abuts against the boss 412 on the cylinder body of the telescopic cylinder 41. The upper clamping rod 42 has second through holes 421 at both ends that are sleeved on the piston rod 411. A step 413 is provided on the piston rod 411. The bottom surface of the upper clamping rod 42 abuts against the step 413 on the piston rod 411. A nut 45 is provided at the upper end of the piston rod 411. The nut 45 fixes the upper clamping rod 42 to the piston rod 411. In this embodiment, the rodless cylinder 5, the first air valve 6, the telescopic cylinder 41, and the second air valve 44 are all connected to the frame 1 by fasteners such as bolts; the rodless cylinder 5 is an RMT series magnetically coupled rodless cylinder; the first air valve 6 and the second air valve 44 are manual valves, but solenoid valves can also be used.

[0013] The system also includes a connecting frame 7 and a controller 8. The connecting frame 7 is positioned between the sealing machine 2 and the slider, with both the sealing machine 2 and the slider connected to the connecting frame 7. Inductive switches 71 are located on the left and right sides of the connecting frame 7. The inductive switches 71 and the controller 8 are electrically connected to the power supply 3, and the inductive switches 71 and the sealing machine 2 are also electrically connected to the controller 8. In this embodiment, the inductive switch 71 is a diffuse reflection photoelectric switch, and the controller 8 is an intermediate relay; other types of controllers, such as a PLC, can also be used.

[0014] The upper clamping rod 42 and the lower clamping rod 43 are arranged along the diagonal of the cylinder body of the telescopic cylinder 41 in the length direction. This arrangement ensures that the bolt and piston rod 411 are distributed in a straight line, and the width of the upper clamping rod 42 and the lower clamping rod 43 can be relatively small.

[0015] In use, first switch the second air valve 44 to raise the upper clamping rod 42, place the packaging bag on the lower clamping rod 43, then switch the second air valve 44 to lower the upper clamping rod 42. After the upper clamping rod 42 and the lower clamping rod 43 clamp the packaging bag, switch the first air valve 6 to make the slider of the slider rodless cylinder 5 drive the sealing machine 2 to move horizontally from left to right. When the right induction switch 71 senses the packaging bag, the induction switch 71 sends a control signal to the controller 8. The controller 8 starts the sealing machine 2. The sealing machine 2 moves horizontally and seals the packaging bag at the same time. When the sealing machine 2 continues to move to the right until the left induction switch 71 moves to the right side of the packaging bag, the sewing thread is broken. At this time, the induction switches 71 on both sides can no longer sense anything, and the induction switches 71 stop sending control signals. The controller 8 opens the sealing machine 2, switches the second air valve 44 to lower the upper clamping rod 42, remove the packaging bag, and switch the first air valve 6 to return the slider to its original position, thus completing one work cycle. By setting the sensor switch 71, the sewing machine can be started and stopped automatically during the translation process, eliminating the need for manual start and stop, making operation more convenient.

[0016] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Simple modifications and substitutions made by those skilled in the art without departing from the spirit and scope of this utility model are within its protection scope.
