Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans, and in particular relates to a transmission connection mechanism for synchronous belt packaging and sealing bags and an intelligent trash can. Background Art

[0002] As a temporary storage device for garbage, trash cans are essential equipment in daily life. When replacing garbage bags in existing traditional trash cans, you need to manually tie the garbage bag tightly, take it out, and then manually put on a new garbage bag, which requires two actions to complete. Traditional trash cans cannot achieve automatic packaging, and traditional garbage bags are not designed to be automatically sealed. Human labor is required to manually seal the bag first; manual sealing is time-consuming, and human hands are likely to touch domestic garbage, which is not conducive to cleaning and hygiene.

[0003] The current technology is: the motor drives the flexible belt to gather the plastic bags for packaging and sealing. After packaging and sealing, the motor reverses to drive the synchronous belt to retreat and reset. This mechanism causes jamming due to the change of direction of the motor. The motor drive gear and the synchronous belt are no longer synchronized. The angle of motor rotation and the angle of synchronous belt laying are inconsistent, causing the synchronous belt to not reset and get stuck. In order to solve the problem of synchronous belt reset and jamming, a new solution and solution idea is needed.

[0004] For example, Chinese patent CN111977218A discloses a flexible packaging mechanism for garbage bags and a garbage can, including a mounting plate, a driving device, a closing mechanism, and a sealing device arranged on the mounting plate. The mounting plate is provided with a mounting plate through hole, and a flexible belt limiting groove is arranged around the mounting plate through hole on the mounting plate. The driving device includes a motor and a reduction transmission gear driven by the motor; the closing mechanism includes a flexible belt arranged around the mounting plate through hole, the head end of the flexible belt is fixed to the mounting plate, the middle part bypasses the sealing end face of the sealing device, and is meshed with the reduction transmission gear, and the end moves back and forth along the flexible belt limiting groove with the rotation of the reduction transmission gear; the flexible belt has high temperature resistant insulation characteristics at least in the part in contact with the sealing end face, and the driving device and the sealing device are communicatively connected to the control device. In this bag sealing and packaging mechanism, the closing mechanism relies entirely on the driving device to drive the reciprocating motion, which has poor reliability and is easy to get stuck and cannot be reset for cyclic packaging.

[0006] The technical solution adopted in the embodiment of the utility model is a transmission connection mechanism for packing and sealing a garbage bag with a synchronous belt, which includes a lower cover. The lower cover is annular. A packing and sealing mechanism is installed on the lower cover. The packing and sealing mechanism includes a heating body, a synchronous belt, and a first motor gear assembly. The heating body is fixed on the inner edge of the lower cover. One end of the synchronous belt is fixed at the place where the heating body is located on the lower cover. The first motor gear assembly is installed on the lower cover and is located on the side of the heating body away from the center of the lower cover. The synchronous belt cooperates with the first motor gear assembly, and the first motor gear assembly is used to tighten / deliver the synchronous belt. It further includes a synchronous laying mechanism for laying the synchronous belt. It can realize the sealing and packing of the garbage bag in the trash can. By tightening / delivering the synchronous belt, the garbage bag is tightened / released. When the synchronous belt is tightened, it cooperates with the heating body to melt and cut the garbage bag to realize the packing and sealing of the garbage bag.

[0007] Further, the synchronous laying mechanism includes a positioning ring block and a second motor gear assembly. The positioning ring block is coaxially fixed on the inner edge of the lower cover. The second motor gear assembly is installed on the lower cover.

A gear set and a pin are installed on the first toothed ring. The gear set meshes with the second toothed ring. The synchronous belt passes between the gear set and the pin, and the gear set and the pin clamp the synchronous belt to lay the synchronous belt following the rotation of the first toothed ring. The synchronous laying mechanism lays the synchronous belt, which helps to improve the reliability of the mechanism and avoid the synchronous belt being stuck and unable to reset for cyclic packing.

[0008] Further, the inner edge of the second toothed ring is configured as a toothed part. The toothed part of the second toothed ring meshes with the gear set, and the diameter of the second toothed ring is larger than that of the first toothed ring. The second toothed ring with a toothed inner edge is convenient for installation and can be fixed from the outer edge of the second toothed ring.

[0012] Further, the heating element is an electric heating block or an electric heating plate.

[0013] Further, a placement groove for cooperating with the synchronous belt is provided on the lower cover, and the free end of the synchronous belt is inserted into the placement groove. The placement groove is used to place the free end of the synchronous belt to prevent the free end from being stuck in the retracted state of the synchronous belt.

The synchronous belt 3 passes between the gear set 9 and the pin 10, and the gear set 9 and the pin 10 clamp the synchronous belt 3 to lay the synchronous belt 3 following the rotation of the first tooth ring 7. The synchronous laying mechanism is used to make the rotation angle of the first tooth ring 7 synchronous with the laying angle of the synchronous belt 3. The gear set 9 includes one or more gears. The gear parameters in the gear set 9 are coordinated to ensure that the rotation angle of the first tooth ring 7 is consistent with the laying angle of the synchronous belt 3.

[0033] The inner edge of the second tooth ring 8 is configured as a tooth part.
