Gear drive type garbage bag side-edge sealing device

Abstract

The invention discloses a gear drive type garbage bag side-edge sealing device which comprises a drive mechanism, a converging and clamping mechanism and a hot melting mechanism. The converging and clamping mechanism comprises a left screw rod, a right screw rod, a pressing plate, a left pressing rod, a right pressing rod, a front push rod, a back push rod and rack moving rods; the left screw rodand the right screw rod are arranged on two sides of a garbage throwing port; the pressing plate is arranged on the left screw rod and the right screw rod; the rack moving rods are arranged on the left side and the right side of the garbage throwing port; the front push rod and the back push rod are arranged on the left side and the right side of the garbage throwing port through a drive gear anda driven gear meshing with each other; the other ends of the front push rod and the back push rod are slidably arranged on the left pressing rod and the right pressing rod; the drive gear meshes withstraight tooth grooves on the rack moving rods; and during work, the left screw rod and the right screw rod drives the pressing plate, the pressing plate drives the left pressing rod and the right pressing rod to push a garbage bag to converge and press tightly through the front push rod and the back push rod. By adopting the structure, the gear drive type garbage bag side-edge sealing device hasthe advantages of simple and reasonable structure, stability and reliability in converging and pressing the garbage bag, good sealing quality, fast speed and the like.

Description

technical field [0001] The invention relates to an intelligent garbage can, in particular to a gear-driven garbage bag side 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 o...

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 first pressing rod and the second pressing rod are intersected on the first fixing rod and the second fixing rod, the first pressing rod When moving with the second pressure rod, one end is stressed, and the stability is poor, especially when the garbage in the garbage bag is heavy, it will be deformed, resulting in the garbage bag not being pressed tightly, and the phenomenon of continuous melting and non-sealing occurs when sealing

The second is that because the garbage bag is gathered to the corner of the handover position for sealing, the length of the pull out is inconsistent when sealing, resulting in a large pulling force on the garbage bag at the opposite corner of the handover position, and even the garbage bag is broken. moving problem

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.
