[0023] The wrapping paper containing tissue paper is placed on the workbench 1, and the connecting rod 33 is pulled so that the connecting rod 33 drives the fixing plate 34 to move upward, thereby driving the spring 32 to be squeezed, and then the wrapping paper containing tissue paper passes through the positioning plate 31 and the fixing frame 2 in sequence, and then the connecting rod 33 is loosened so that the squeezing force of the spring 32 is reduced, and then the connecting rod 33 is moved downward by the elasticity of the spring 32, thereby driving the fixing plate 34 to move downward to squeeze the wrapping paper that has passed through the positioning plate 31, and then the wrapping paper is fixed on the workbench 1, and then the wrapping paper that has passed through the fixing frame 2 is heated and sealed by the sealing mechanism 6, and then the positioning member 3 is provided to prevent the seal from tilting during the sealing process.

[0024] The sealing mechanism 6 includes a hydraulic cylinder 61, a heating element 62, a heat-conducting cover 63 and a movable plate 64. The hydraulic cylinder 61 is fixed to the top of the fixed frame 2. The telescopic end of the hydraulic cylinder 61 passes through the fixed frame 2 and is fixedly connected to the movable plate 64. The heat-conducting cover 63 is movably connected to the movable plate 64. The heating element 62 is fixed on the movable plate 64 and is located between the movable plate 64 and the heat-conducting cover 63.

[0025] By placing the packaging paper on the workbench 1, the hydraulic cylinder 61 is started to extend the telescopic end of the hydraulic cylinder 61, and then the movable plate 64 is moved, and then the heating element 62 is started to increase its temperature, and then the heat generated by the heating element 62 is transferred to the heat-conducting cover 63, so that the temperature of the heat-conducting cover 63 increases, and as the movable plate 64 moves downward, the heat-conducting cover 63 is driven to move until the heat-conducting cover 63 contacts the packaging paper, and then the packaging bag is heated and sealed.

[0026] The heat-conducting cover 63 is detachably connected to the sliding plate. Four connecting plates 8 arranged in a rectangular shape are fixed on the heat-conducting cover 63. The four connecting plates 8 are provided with claws 9. The movable plate 64 is provided with four connecting grooves 10 corresponding to the four connecting plates 8. The connecting plate 8 is also provided with four card slots 11 respectively connected to the four connecting grooves 10. The four connecting plates 8 are respectively extended into the four connecting grooves 10 and the claws 9 on the four connecting plates 8 are respectively placed in the four card slots 11 for card connection;

[0027] By squeezing the claw 9 so that the claw 9 extends into the slot 11 until the claw 9 moves into the connecting slot 10, the heat-conducting cover 63 is taken out from the movable plate 64, thereby achieving the disassembly effect of the heat-conducting cover 63 on the movable plate 64, and then the disassembled heat-conducting cover 63 is cleaned and replaced, thereby extending the service life of the heat-conducting cover 63.

[0029] The motor 42 is started to drive the shaft 7 to rotate, and the shaft 7 drives the fan 43 to rotate, so that the fan 43 rotates to generate wind force, and the generated wind force quickly cools the heated and sealed packaging bag through the air vents 5, thereby preventing the seal from cooling slowly and causing it to open again.

[0030] The fixed frame 2 has two corresponding guide grooves 12, and guide blocks 13 are provided on both sides of the movable plate 64. The two guide blocks 13 are respectively placed in the corresponding guide grooves 12 for movement;

[0031] The guide block 13 plays a guiding role, so that the hydraulic cylinder 61 drives the moving plate 64 to move more stably.

[0032] Working principle: first, place the packaging bag containing tissue paper on the workbench 1, then stretch the connecting rod 33 upward to drive the fixed plate 34 to move upward, and at the same time, the fixed plate 34 squeezes the spring 32 to make the spring 32 contract, and then the packaging paper passes through the positioning plate 31 and the fixing frame 2 in sequence, and then the connecting rod 33 is loosened to reduce the squeezing force of the spring 32, and then the spring 32 is elastically moved downward until the fixed plate 34 is squeezed with the packaging bag passing through the positioning plate 31, and when the hydraulic cylinder 61 is started, the telescopic end of the hydraulic cylinder 61 is extended to drive the moving plate 64 to move, and then the moving plate 64 drives the guide block 13 to move in the guide groove 12, At the same time, the heating element 62 is heated, and the temperature generated by the heating element 62 is transferred to the heat-conducting cover 63, so that the surface temperature of the heat-conducting cover 63 rises, until the heat-conducting cover 63 is pressed against the packaging bag passing through the fixing frame 2 to heat and seal it, and at the same time, the motor 42 is started to operate, thereby driving the rotating shaft 7 to rotate, and the rotating shaft 7 drives the fan 43 to rotate, thereby generating wind force, and the cold wind is transferred to the packaging bag that is being heat-sealed through ventilation to quickly cool it, thereby avoiding slow cooling of the seal and causing it to open again, and finally the telescopic end of the hydraulic cylinder 61 is contracted, thereby driving the movable plate 64 to move upward, thereby moving the heat-conducting cover 63 away from the packaging bag.
