A spacing adjustment mechanism 50 is connected between the two telescopic columns 40. A cylinder 60 is fixedly installed on the top surface of the installation top plate 10, which can drive the spacing adjustment mechanism 50 to move up and down. The bottom end of the cylinder 60 is fixedly installed on the top of the spacing adjustment mechanism 50, and a pair of extrusion mechanisms 70 are fixedly installed at the bottom of the spacing adjustment mechanism 50. A hose inner wall heating mechanism 80 is installed at one end of the spacing adjustment mechanism 50.

[0023] Specifically, the spacing adjustment mechanism 50 includes a long box 51, a flange 52 is installed on the front side of the long box 51, a gear is provided inside the long box 51 and is transmission-connected to the flange 52, the upper and lower inner walls of the long box 51 are slidably connected to racks 53, the two racks 53 are meshed with the gears, the two racks 53 extend to the outside of the long box 51, and the ends of the two racks 53 away from the long box 51 are fixedly connected to a long plate 54.

[0024] In this embodiment, the rotating flange 52 can drive the gear to rotate, and the gear drives the two racks 53 to move closer to each other or move away from each other, so as to adjust the distance between the electric heating block 83, the electric heating sheet 100 and the clamping plate 200. After adjustment, align the round holes on the flange 52 with the mounting holes on the front of the long box 51 and fix them with bolts, so that it can be applied to packaging hoses placed at different distances, further improving the scope of use and meeting the actual needs.

[0025] Specifically, the extrusion mechanism 70 includes a pair of connecting rods 71. Slide seats 72 are slidably inserted into the sides of the two connecting rods 71 close to each other. Extrusion plates 73 are fixedly connected to the sides of the two slide seats 72 close to each other. A pair of connecting slots 74 are opened on the sides of the two extrusion plates 73 away from each other. Lifting slide members 75 are inclinedly inserted into the tops of the two extrusion plates 73.

[0026] In this embodiment, when the lifting slide member 75 moves downward, it can drive the two extrusion plates 73 to move closer to each other, thereby realizing the function of clamping and extrusion.

[0027] Specifically, electric heating sheets 100 that are snap-connected to the connecting slots 74 are provided on the sides of one pair of extrusion plates 73 close to each other, and clamping plates 200 that are snap-connected to the connecting slots 74 are provided on the sides of the other pair of extrusion plates 73 close to each other.

[0028] In this embodiment, the electric heating sheet 100 heats the outer wall of the packaging hose and plays a role in preliminary sealing, while the clamping plate 200 further extrudes the seal, which can improve the sealing quality.

[0029] Specifically, one of the lifting slide members 75 is fixedly installed on the bottom surface of the long box 51, and the other lifting slide member 75 is fixedly installed on the bottom surface of one of the long plates 54. A pair of second chutes 300 are opened on the bottom surface of the mounting top plate 10. Second sliders 400 are slidably connected to the two second chutes 300. One pair of connecting rods 71 is fixedly installed on the bottom surface of the second slider 400, and the other pair of connecting rods 71 is fixedly installed on the bottom surface of the mounting top plate 10.

[0030] In this embodiment, it plays a role in fixedly installing the connecting rod 71 and does not interfere with the distance adjustment of the distance adjustment mechanism 50.

[0031] Specifically, the inner wall heating mechanism 80 of the hose includes a mounting sleeve 81. The mounting sleeve 81 is fixedly installed on the long plate 54. The bottom end of the mounting sleeve 81 is threadedly connected with a long rod 82. The bottom end of the long rod 82 is fixedly connected with an electric heating block 83.

[0032] In this embodiment, it can be inserted into the un-sealed packaging hose when moving downward, and can heat the inner wall of the packaging hose, thus facilitating subsequent sealing.

[0033] Working principle and usage process of the utility model: The conveyor belt below transports the packaging hoses filled with items (such as toothpaste, cosmetics, food, etc.). When it moves below the packaging hose sealing device, the air cylinder 60 is started to drive the entire spacing adjustment mechanism 50 to move downward. At this time, the telescopic column 40 extends. Since the inner wall heating mechanism 80 of the hose is fixedly installed on the spacing adjustment mechanism 50, the electric heating block 83 in the inner wall heating mechanism 80 of the hose is inserted into the packaging hose to achieve inner wall heating. At the same time, the lifting slider 75 in the extrusion mechanism 70 moves downward and drives the sliding seat 72 to move horizontally. At this time, the two extrusion plates 73 move closer to each other, and the electric heating sheet 100 heats the outer wall of the packaging hose and performs preliminary sealing, while the clamping plate 200 extrudes the sealed packaging hose to achieve final sealing.
