For intelligent trash cans with automatic bagging mechanisms, the automatic bagging mechanisms typically include a closing mechanism that draws in and compresses the trash bag opening, and a sealing device that seals and cuts the trash bag from the closing mechanism.

In the automatic packaging mechanism in the prior art, the closing mechanism adopts two crossed bag-collecting pressure rods and a closing-up bag-sealing pressure rod, the bag-collecting pressure rods firstly collect the opening of a garbage bag to the front of a sealing device under the drive of two sets of driving devices, and then the closing-up bag-sealing pressure rods further close up and tightly press the garbage bag concentrated in the front of the sealing device on the sealing device to finish the sealing and packaging. And some automatic packing mechanisms adopt a single pressure rod to pack the opening of the garbage bag to the front of the sealing device on one side of the garbage can, and at the moment, the length of the base meeting the sealing requirement is distributed along one side of the garbage putting opening. The depression bar further compresses tightly and seals the disposal bag in base the place ahead, accomplishes and seals the packing, and foretell disposal bag packing structure is stable relatively, seals the effect better.

In the automatic packing mechanism in the prior art, the sealing device having both sealing and cutting functions generally includes a heating wire and a base for supporting the heating wire. However, in the existing sealing device, when the closing bag sealing pressure rod draws the garbage bag to the sealing end surface on the base, because the garbage bag material is not uniformly distributed along the sealing end surface of the base, the base at the thick part of the garbage bag material is stressed greatly, and the base at the thin part of the garbage bag material is stressed less; or the compression bar generates small deformation, so that the stress is larger when the garbage bag at the position where the compression bar is tightly contacted with the base is sealed, the sealing quality is higher, the stress is smaller when the garbage bag at the position where the compression bar is looser contacted with the base is sealed, the sealing quality is poorer, the phenomena of unsealed garbage bag seal, weak sealing strength, continuous cutting and the like occur, and the sealing and cutting quality of the garbage bag is influenced.

In addition, in the existing sealing device, the heating wire is easy to loose and shift on the base, so that the garbage bag is unevenly heated during sealing, and the sealing quality is reduced.

Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings by specific embodiments. It should be understood that the following examples are illustrative only and are not intended to limit the scope of the present invention.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus or methods consistent with certain aspects of the application, as detailed in the claims that follow.

As shown in fig. 1 to 3, the sealing device for garbage bags according to the first embodiment of the present invention comprises a heating wire 10, a base 20 for supporting the heating wire 10, and two adjusting springs 30 for adjusting the force balance of the base 20, wherein:

After the sealing device for the garbage bag is assembled, one end of the adjusting spring 30 abuts against the second end surface 212 of the base, the other end abuts against the garbage can, and the base 20 is deflectably mounted on the garbage can.

When the sealing operation is performed, the end of the base 20, which is subjected to a larger force, deflects toward the second end surface 212, and the adjusting spring 30 at the corresponding end is compressed, thereby maintaining the force balance of the base 20.

It should be noted that, in the prior art, the base 20 can be mounted on the trash can in a plurality of ways, such as:

In this fixing manner, when the sealing operation is performed, since the base 20 is unevenly stressed, the base 20 rotates around the fixing member as an axis, so that the end of the base 20 with a larger stress deflects toward the second end surface 212, and the adjusting spring 30 at the end with a larger stress is compressed, thereby maintaining the stress balance of the base 20.

Note that the inside diameter of the fixing hole 21 is slightly smaller than the outside diameter of the head of the fixing member (screw head), so that the base 20 is only rotatable but not freely movable in the length direction of the fixing member (for example, when the base is horizontally installed, the base cannot be moved up and down).

Alternatively, as shown in fig. 4, two elongated second fixing holes 22 are symmetrically formed in the base 20, and two fixing members (e.g., screws) respectively penetrate through the corresponding second fixing holes 22 to mount the base on the trash can.

It should be noted that the range of the deflection is not arbitrary, and the range defined by the second fixing hole 20 and the reaction force of the adjustment spring 30 are defined together.

Preferably, the fixing hole 22 is a waist hole. Further preferably, the fixing holes 22 are arc-shaped waist holes, and the arc-shaped waist holes respectively use the axial center of the other opposite fixing piece as the center of a circle.

The utility model discloses a disposal bag closing device, after the disposal bag binding off, the disposal bag material is inhomogeneous on base 20's the terminal surface that seals, or when the depression bar takes place to deform, the great one end of base 20 atress to second terminal surface 211 one side deflects, and the adjusting spring 30 that corresponds one end is compressed, so that the less one end of base 20 atress and the contact that the depression bar can be more abundant, thereby ensure the base reaches the atress balance, simultaneously the less one end of base atress with the heater contact is more even, makes the quality of sealing of disposal bag keeps the homogeneous on the length of sealing of base. Compare in base 20 and the complete fixed connection's of garbage bin structure, the utility model discloses a disposal bag closing device can reply the back base that closes up more reliably and seal the terminal surface on the disposal bag material inhomogeneous, or the depression bar takes place the condition of deformation, can ensure to seal the quality more even unanimity, has improved closing device's compatibility and self-adaptation ability, has improved the stability of system, can adapt to the more complicated condition of sealing.

In this embodiment, the fixing member may also be a combination of a screw and a washer.

Further, the base 20 is mounted on a mounting plate of the trash can.

According to the utility model discloses, adjusting spring 30 mainly plays the guarantee base 20 is whole seals the effect of balanced stress on the length to the heater fully contacts with the disposal bag when guaranteeing to seal, and guarantees to seal the firmness even unanimous, guarantees to seal the quality. Preferably, the adjusting spring 30 is a compression spring.

Moreover, the ceramic also has good insulating and heat-insulating properties and can resist the working temperature of the heating wire during working. When the temperature of the heating wire is higher, the base can be prevented from being deformed and damaged by high temperature, and the leakage of the equipment can be prevented. Moreover, the adhesion of the garbage bags can be prevented, the garbage bags are prevented from being damaged, dirt accumulation of the hot melting device is avoided, and the automatic packaging quality and the stability and reliability of the performance of the intelligent garbage can are improved. Of course, the material of the base 20 is not limited to the ceramic material, and may be other heat-resistant insulating material or other material subjected to heat-resistant insulating treatment.

Further, the first end face 211 of the base 20 is provided with an anti-sticking coating, when the heating wire is in contact with the garbage bag and is subjected to hot melting, the molten garbage bag is not easily adhered to the hot melting device, and the good performance of the hot melting device is ensured.
