Among the prior art, the garbage bin that has automatic packing function packs through disposal bag packaging mechanism usually, and disposal bag packaging mechanism includes binding off mechanism and closing device, and closing device usually draws in the disposal bag melting and the sealing of closing off mechanism to closing device department through electric heating element. The commonly used sealing device comprises a heating wire for hot melting and sealing and a base with high-temperature-resistant insulating property for supporting and fixing the heating wire. However, the sealing device of the prior art has the following technical disadvantages.

Firstly, the tensioning of the heating wire is achieved by a relatively complex tensioning structure. The difficulty of processing and forming the base is increased, and the production cost is increased.

Secondly, according to the difference of the structure of the closing mechanism, the base matched with the closing mechanism is different in adaptability. The sealing end face of the base in the prior art is a plane, and is generally suitable for a closing mechanism for closing a single rigid pressure rod or a closing mechanism for closing a crossed rigid pressure rod (for example, a packaging mechanism disclosed in CN 108584238A). For the closing mechanism using flexible belt (such as rope) to close, it needs to be improved on the basis of the existing base structure, so as to make it better suitable for the sealing requirement of the flexible packaging mechanism (such as closing by flexible belt such as rope).

In addition, in the current packaging mechanism for flexible binding off, the heater of base is difficult for tensioning, fixed, causes the heater deflection easily, directly leads to sealing the asymmetry, seals intensity quality and descends, and the heater deflects high temperature resistant base when serious, leads to the garbage bin structure to be scalded by the high temperature of heater and destroys, makes the potential safety hazard appear in the machine, even unable use. In order to limit the heating wire, a heating wire limiting groove is usually formed in the sealing end face of the base, but the melting and impurity stain accumulation of the garbage bag is easily caused in the limiting groove, so that the sealing quality is influenced. Meanwhile, through holes or through grooves are formed in two ends of the base so as to limit the heating wire, and the heating wire is prevented from being deviated. However, the through holes or the through grooves are formed, the overall processing difficulty of the base is increased, the production cost is high, the garbage bag melting impurity stains are easy to accumulate in the through holes or the through grooves, and the potential safety hazard of the device is increased.

Therefore, how to simply and reliably fix the heating wire so that the heating wire is always kept in a tensioning state and is positioned in the middle position of the base, the safety and the reliability of the sealing device in the flexible closing garbage bag packaging mechanism are further improved, the sealing quality is improved, the automatic packaging cost is reduced, and the important technical problem to be solved by professionals in the field is solved.
