[0007] By adopting the above technical scheme, when the band-aid is packaged using an independent packaging device, the transmission component is started, and the transmission component drives the heat-sealing roller to rotate. At this time, the two packaging films are located between the heat-sealing rollers, and the heat-sealing rings are used to heat-seal the two lateral sides of the band-aid package. At the same time, when the heat-sealing blocks located on the circumferential outer walls of the two heat-sealing rollers are abutted, the packaging film in the length direction of the band-aid is also heat-sealed, thereby realizing the packaging of the band-aid.

[0009] By adopting the above technical solution, the transmission motor is started, and the transmission motor drives the heat sealing roller connected to the transmission motor to rotate. At this time, under the action of the driving gear, the kinetic energy is transmitted to the driven gear through the driving gear, thereby achieving the effect of driving the remaining heat sealing roller to rotate. At the same time, under the action of the transmission component, the packaging film can be transmitted in the same direction, and the effect of one power source driving the rotation of two heat sealing rollers is achieved.

When the external tool abuts against the unlocking rod, the unlocking rod drives the connecting rod to move toward the side close to each other, and at this time the connecting block moves toward the side close to each other, and at this time the connecting block is pulled out from the clamping hole, and then the connecting tube can be taken out from the plug-in hole, thereby achieving the effect of separating the heat sealing block from the heat sealing roller, thereby achieving the effect of improving the applicability of the independent guarantee equipment.

[0018] Preferably, the side walls of the connecting block which are away from each other are gradually inclined from the side close to the heat sealing block to the side far away from the heat sealing block toward the side close to each other.
