In addition, the mechanism can adjust the target gathering position, the adjusting range is in a circular ring shape, and the requirements of specific work can be met. The automatic bag binding device is particularly suitable for an automatic bag binding link in an intelligent closestool and an intelligent garbage can.

Description

Technical Field

[0001] The utility model relates to the technical field of plastic bag sealing, in particular to an annular flexible rope tightening mechanism. Background Art

[0002] In recent years, with the rapid growth of my country's economy and the significant increase in national income, people's lives have gradually moved towards automation and intelligence. Among them, plastic bag sealing has basically achieved the transformation from manual to automatic. Most plastic bag sealing technologies use a closing mechanism. However, the traditional closing mechanism has a single closing position and causes serious wear and tear on plastic bags. Therefore, the traditional closing mechanism cannot meet the needs of various plastic bags to complete automatic sealing, and it is very urgent to find a new closing mechanism.

[0003] Patent CN106275783A discloses a plastic bag sealing clamp, including a first movable part and a second movable part, one end of the first movable part and one end of the second movable part are rotatably connected, the other end of the first movable part is provided with a fixing hole, the other end of the second movable part is provided with a wedge block, and the wedge block matches the fixing hole. The advantages of the plastic bag sealing clamp of this utility model are: fewer parts, simpler structure, lower production cost, reliable quality, able to firmly fix the plastic bag, and simple and convenient operation. However, this sealing clamp seems convenient but does not seal tightly, and requires manual operation to achieve the sealing operation. Although it will not wear the plastic bag, it cannot be sealed if there is not enough room left at the bag opening.

[0004] Patent CN108438370A discloses a plastic bag sealing machine, whose structure includes a heat-conducting layer, a packaging operation device, a rotating shaft, a pressing and cooling device, a pressure-assisting block, a heat-conducting pressing block, a purification liquid access terminal, and a protective base. It is characterized in that: the packaging operation device includes a power box to be triggered, a sliding purification cover, an electric heating device, a constant temperature heat exhaust device, a press-release purification box, an air pump push device, a telescopic push bracket, a reset pull wheel, and a protective shell; the power box to be triggered is installed on the inner surface of the protective shell, the sliding purification cover is embedded and installed inside the protective shell, and the electric heating device is installed above the sliding purification cover. However, this sealing machine only seals the plastic bag in a straight line. Although it will not cause wear and tear to the plastic bag, the sealing shape is not suitable, resulting in a decrease in the strength of the plastic bag after sealing. Utility Model Content
