Rack transmission type garbage bag sealing device

Abstract

The invention creatively discloses a rack transmission type garbage bag sealing device. The device comprises a driving mechanism, a folding and clamping mechanism and a hot melting mechanism, whereinthe hot melting mechanism is fixed in the middle of the left side of a barrel cover, the folding and clamping mechanism comprises a screw rod, a main push rod, a transmission gear, a front-back push rod and an up-down rack, the screw is arranged on the rear side of a garbage throwing opening, the main push rod is arranged on the screw rod, the transmission gear is arranged on the left side of thegarbage throwing opening, the up-down rack is correspondingly meshed on the transmission gear, the driving mechanism drives the screw rod and the transmission gear to rotate, the main push rod pushesa garbage bag to be folded towards the hot melting mechanism, the transmission gear drives the front-back push rod to push the garbage bag to be folded towards the middle through the up-down rack, andthe front-back push rod and the main push rod are together used for making the garbage bag to be clamped on the hot melting mechanism for fusing and up-down sealing. After the structure is adopted, the advantages that the structure is simple and reasonable, folding and pressing of the garbage bag is stable and reliable, the sealing quality is good, and the speed is high are achieved.

Description

technical field [0001] The invention relates to an intelligent garbage can, in particular to a rack-driven garbage bag sealing device suitable for sealing the pull-type garbage bag of the intelligent garbage can. Background technique [0002] With the rapid development of the economy and the continuous improvement of living standards, people have higher and higher requirements for hygiene, and trash cans have also been continuously improved. The open-top trash cans used in the early days have the advantages of simple structure, convenient use, and low production cost, but there are the following problems in the process of use: the garbage is directly exposed to people's sight without a cover, which is very unsightly, and the garbage in the bucket smells bad. Emanating from the delivery port will still cause secondary pollution to the surrounding environment. The clamshell trash can used in the later period uses the foot pedal to drive the push rod to drive the lid to open t...

Problems solved by technology

The open-top trash cans used in the early days have the advantages of simple structure, convenient use, and low production cost, but there are the following problems in the process of use: the garbage is directly exposed to people's sight without a cover, which is very unsightly, and the garbage in the bucket smells bad. Emanating from the discharge port will still cause secondary pollution to the surrounding environment

The smart trash cans currently in use generally realize the function of automatically opening the lid through a sensor device, and there is no contact with the trash can and garbage when putting in the trash. Other advantages and disadvantages are basically the same as those of the flip-top trash can.

Although the above three types of garbage cans can use plastic garbage bags to clean up the garbage without leaving dirt, because the garbage bags cannot be automatically sealed, not only can you see the garbage when you change the garbage bag, but you will also smell the peculiar smell of the garbage. In summer, the garbage smells bad and smells bad, needs further improvement

[0003] In order to solve the above problems, the Chinese invention patent application publication number CN108584238A discloses a garbage bag packing mechanism and an intelligent garbage can. At the handover position of the second fixed side, the garbage bags gathered to the handover position are hot-melt-sealed through the hot-melt device, so as to solve the problem that the existing intelligent garbage can has no automatic packing mechanism or can only pack garbage bags semi-automatically and the garbage bags are packed and sealed. However, there are the following problems in the process of use: First, because the garbage bag is folded to the corner of the handover position for sealing, the length of the pull out is inconsistent when sealing, resulting in garbage at the corner of the handover position. The bag is subjected to a large pulling force, even breaking the garbage bag, and there is still the problem of not being able to pull it

The third is that two motors need to be driven step by step to complete the collection of garbage bags. The sealing time is long, the efficiency is low, and the production cost is high. Further improvement is needed.

For this reason, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out.
