[0033] like Figure 2 As shown, in order to facilitate the connection and fixation of the sleeve plate 31 to the support rod, as a preferred embodiment of the present invention, the deformation sleeve 3 is connected to the support rod 2 on the corresponding side through a connecting portion 4; the connecting portion 4 is arranged on the sleeve plate 31 or on the hinge shaft between the sleeve plates 31.

[0034] like Figure 4 As shown, in order to facilitate the assembly and disassembly of the clamping sleeve 6, as a preferred embodiment of the present invention, the side edges of the clamping sleeve 6 are vertically disconnected and then connected to each other through a detachable connector. The connector 65 is a zipper, a snap button, or a Velcro.

[0035] like Figure 1 As shown in a preferred embodiment, the support rod 2 is composed of a cross bar 21 and a hanging piece 22; the deformation sleeve 3 is arranged on the cross bar 21; and the sealing and separating device 8 is arranged on the hanging piece 22.

[0039] In a preferred embodiment, a heating wire is provided on the main sealing member 81 .

[0040] In a preferred embodiment, two or three heating wires are arranged parallel to each other at intervals. One of the heating wires performs a sealing operation on the soft bag, and the other heating wire performs a fusing operation on the soft bag. The cross section of the heating wire at the upper end is flat, and the heating wire at the lower end is cylindrical.

The closing sleeve 61 is used to be connected and fixed with the deformation sleeve 3 or connected and fixed with the fence member 5.

[0045] The method of using the device includes the following steps:

[0046] Preset packaging bag: open the clamping sleeve 6, fold the soft bag 9 of the long sleeve structure with open ends or one end open and the other end sealed in an N-shaped tube shape or in a retractable threaded tube shape or curled tube shape, and put it on the deformation sleeve 3, or set it in the clamping sleeve 6, that is, in the storage cavity between the clamping sleeve 6 and the deformation sleeve 3. If one end of the soft bag 9 is sealed, turn the sealed end downward, and then use the clamping sleeve 6 to clamp the soft bag 9 folded in the storage cavity, and extend the lower end of the soft bag 9 from the lower end of the clamping sleeve 6. If the deformation sleeve 3 is provided with a fence 5, the soft bag 9 is put on the outer wall of the deformation sleeve 3 and is located in the gap between the fence 5 and the deformation sleeve 3.

[0047] Preparation before loading: When the preset soft bag 9 is open at both ends, the first sealing is required first, the lower end of the soft bag 9 is extended, and the lower end of the soft bag 9 extends downward beyond the position of the sealing separation device 8, and the sealing separation device 8 is started, so that the sealing separation device 8 seals the lower end of the soft bag 9, and then enters the fourth step of loading; when the lower end of the preset soft bag 9 is sealed, the fourth step of loading can be directly entered;

[0048] First sealing: first control the support rod 2 to close, so that the main sealing member 81 and the auxiliary sealing member 82 are closed to clamp the soft bag, and at the same time, the heating wire 83 is energized to seal the lower end of the soft bag; if there are two heating wires on the main sealing member 81, the lower end of the soft bag can be sealed and then separated.

[0049] Loading: Open the two support rods 2 to open the deformation sleeve 3, and load the items to be loaded into the soft bag 9 from the end of the deformation sleeve 3;

[0050] Sealing separation: Control the support rod 2 to close, so that the main sealing part 81 and the auxiliary sealing part 82 are closed to clamp the soft bag, and then start the motor or pull the control rod to start the sealing separation device 8, so that the auxiliary sealing part 82 is turned over and cooperates with the main sealing part 81 to clamp the soft bag. At the same time, the heating wire 83 is energized to seal the lower end of the soft bag; if there are two heating wires on the main sealing part 81, the lower end of the soft bag can be sealed and then separated.

[0051] Bag taking: Take out the separated soft bag 9 filled with items from below the sealing and separating device.

[0052] When the device of the present invention performs a sealing operation on a soft packaging bag, the opening of the soft packaging bag can be melted and sealed by heating the material of the soft packaging bag at the opening, or the opening of the soft packaging bag can be sewed by a binding device, or the sealing effect can be achieved by tying with tape or rope; when the sealed soft packaging bag is separated, the upper and lower separation can be achieved by cutting and pressing with a single blade or cutting back and forth, or the separation effect can be achieved by shearing with the knives interlocking with each other.
