Technical Field

[0001] The utility model belongs to the field of trash cans, and in particular relates to a swing arm bag collecting mechanism of a trash can. Background Art

[0002] With the increasing importance of environmental protection, more and more people are aware that improper garbage disposal may cause pollution to the environment, so the demand for automatic bag collection equipment has increased. With the development of technologies such as machinery, automation and artificial intelligence, more and more companies are committed to developing automatic bag collection equipment to improve efficiency, reduce manual intervention and reduce costs. Some regions have implemented garbage sorting policies, which require more automatic bag collection equipment to handle different types of garbage bags. With the improvement of people's living standards, the amount of garbage generated is also increasing, which provides a broad market for automatic garbage bag collection equipment. Most of the existing garbage bins are manually packed, which is inconvenient. They need to directly contact various types of garbage during the packaging process, and the operation is not clean and hygienic. Some automatic packaging devices with mechanical structures are complex in design and fail to achieve fully automatic packaging.

[0003] The Chinese patent with publication number CN213833104U discloses an automatic packing type trash can, which is mainly packed by pulling the drawstring of the trash bag by a pulling assembly. There are problems such as loose packing during the packing process, and full automatic packing is not achieved.

[0004] Therefore, in view of the problems existing in the prior art, it is urgently necessary to provide a swing arm bag collecting mechanism for a trash can to solve the problems existing in the prior art. Summary of the invention

By setting a structure of two holding rods and a pressure rod, the two holding rods rotate to form a Y-shaped holding rod, and the pressure rod translates to clamp the trash bag together with the two holding rods and fuse the seal to achieve automatic bag collection.

[0006] The utility model is achieved in this way:

[0007] A swing arm bag collecting mechanism for a trash can comprises a driving frame arranged in a trash can cover and a pressure rod movable in the driving frame, wherein the driving frame comprises a driving rod and transmission frames connected to both ends of the driving rod, the pressure rod is located between the two transmission frames, and the pressure rod reciprocates along the transmission frame under the action of the driving rod;

[0008] A fixed shaft and two holding rods are also provided on one side away from the driving rod in the direction of the transmission frame. One end of the two holding rods is fixed on the fixed shaft, and the other end extends to the transmission frames on both sides respectively. When one end of the two holding rods rotates around the fixed shaft together, the other end thereof is driven to move on the transmission frames on both sides respectively. The rotation directions of the two holding rods are opposite.

[0009] A welding portion is also provided at the position of the fixed axis, and a welding joint is provided on the side of the pressure rod facing the fixed axis; when the two holding rods rotate around the fixed axis, the angle between the two holding rods becomes smaller, and the pressure rod begins to move along the transmission frame toward the welding portion and crosses with the two holding rods, tightening the garbage bag in the enclosed area, and at the same time the welding portion is connected to the welding joint to melt the garbage bag.

[0010] Preferably, a transmission rod is respectively provided in the middle of the two holding rods, and a rotating shaft is provided at both ends of the transmission rod, one end of which is connected to the holding rod through the rotating shaft, and the other end is connected to the guide rod through the rotating shaft;

[0013] Specifically, when the bags are not collected, the two arms will be in a straight line and stop together with the transmission rod on the left and right of the fixed axis. When the bags are collected, the two arms will rotate around the fixed axis to form a Y shape, and the angle formed between the two arms is less than 90 degrees.

[0014] Preferably, the two guide rods are arranged in parallel on a side of the fixed shaft away from the pressure rod;

[0015] Part of the sections of the two guide rods on the opposite sides are sawtooth surfaces, a driving gear is arranged between the two sawtooth surfaces, and the driving gear is meshed with the two sawtooth surfaces;

[0016] When the driving gear rotates, it drives the two guide rods to move in parallel, and the two guide rods move in opposite directions.

[0017] Specifically, the two guide rods drive the transmission rod to move through translational motion, and the transmission rod drives the two holding rods to rotate around the fixed axis.

[0018] Preferably, the guide rod far from the fixed axis is a first guide rod, and the guide rod close to the fixed axis is a second guide rod;

[0031] Preferably, guide rods are respectively provided between the conveyor belt and the transmission frame, the guide rods are parallel to the transmission frame, through holes adapted to the positions of the guide rods are provided at both ends of the pressure rod, and the guide rods pass through the through holes at both ends of the pressure rod.

[0033] Preferably, two ends of the transmission frame are respectively provided with a direction-changing switch, and the direction-changing switch is located at a layer corresponding to the pressure rod.

[0034] Specifically, when the pressure rod contacts the direction-changing switch on the side where the fixed shaft is located while moving along the transmission frame, the garbage bag is clamped, the pressure rod stops moving and fuses the garbage bag; when the pressure rod contacts the direction-changing switch on the other side, it stops moving and resets.

[0035] Specifically, an annular groove is provided at the upper end of the barrel cover, and the garbage bag is placed in the annular groove.

[0036] Specifically, the garbage bag is a ring-shaped garbage bag, which is arranged at the upper end of the bag collecting mechanism, and the sealing and disconnection between the garbage bags are achieved by fusing.
