Referring to fig. 1 to 6, the present embodiment further provides a garbage bag for automatic bagging, which aims to solve the following problems: how to cooperate and trade a bag garbage bin automatically and realize trading the bag automatically, prevent that people from forgetting to sheathe in new disposal bag before losing rubbish. The bag comprises a bag body 100, wherein the bag body 100 is provided with a bag surface A110 and a bag surface B120 which are oppositely arranged, a bag surface C130 and a bag surface D140 which are used for connecting the bag surface A110 and the bag surface B120 are arranged between the bag surface A110 and the bag surface B120, the bag body 100 which can contain garbage is formed by the bag surface A110, the bag surface B120, the bag surface C130 and the bag surface D140, a bag surface A is respectively provided with a bag part A, a bag part B is respectively provided on the bag surface B120, and the bag parts A and B are used for enabling a bag mechanism 600 to separate the bag surface A110 and the bag surface B120 so that the bag body 100 is unfolded to form an area for containing garbage.

When the garbage bag is used, the bag dividing mechanism 600 separates the bag faces 110 and 120 by moving the bag dividing portions a and B away from each other, and the bag body 100 is unfolded to form an area capable of containing garbage.

The garbage bag for automatic bagging provided by the embodiment can be implemented by matching with an automatic bagging garbage can, and is a bag body 100 for containing garbage and composed of a bag surface A110, a bag surface B120, a bag surface C130 and a bag surface D140, wherein the bag surface A110 and the bag surface B120 are respectively provided with a bag part A and a bag part B, and the bag part A and the bag part B are operated by a bag separating mechanism 600 on the automatic bagging garbage can when in use, so that the bag surface A110 and the bag surface B120 are separated to enable the bag body 100 to be unfolded.

In order to use the garbage bag conveniently, the lifting mechanism 150 for lifting the bag body 100 is arranged on the bag body 100, and the bag body can be taken out from the garbage can after the garbage bag is filled with garbage by arranging the lifting mechanism 150, so that the garbage can be lifted by a person conveniently or the garbage can be packed and treated.

Specifically, the lifting mechanism 150 includes an a lifting portion 151 and a B lifting portion 152, and the a lifting portion 151 and the B lifting portion 152 are respectively provided on the a bag surface 110 and the B bag surface 120. The A lifting part 151 and the B lifting part 152 are respectively arranged at the upper parts of the A bag surface 110 and the B bag surface 120, so that an operator can conveniently lift the garbage bag by using A, B lifting parts 152 after taking the garbage bag from the garbage can; if the a lifting part 151 and the B lifting part 152 are provided on the C bag surface 130 and the D bag surface 140, respectively, it is necessary to change the posture after the disposal bag is removed to lift the disposal bag, which is obviously inconvenient.

The bag dividing part A is composed of a limiting mechanism A, the limiting mechanism A is used for limiting the movement of the bag surface A110 to the side close to the bag surface B120, so that the phenomenon that the bag surface A110 moves to the bag surface B120 when the bag dividing mechanism 600 separates and unfolds the bag surface A110 and the bag surface B120 can be prevented, the bag dividing mechanism 600 can reliably unfold the garbage bag, and automatic bag sleeving is realized.

The bag B dividing portion is configured by a B connecting mechanism for connecting the bag B surface 120 and the bag dividing mechanism 600. The bag body 100 can be unfolded by limiting the movement of the bag surface A110 to the bag surface B120 by the limiting mechanism A, connecting the bag connecting mechanism B with the bag separating mechanism 600, and moving the bag surface B120 to the side far away from the bag surface A110 by the bag separating mechanism 600.

The B-link mechanism is formed by a B-cut portion 121 provided on the upper side portion of the B-pocket surface 120, a position on the a-pocket surface 110 corresponding to the B-cut portion 121 is referred to as an a-pocket surface portion 113, and the a-pocket surface portion 113 prevents the bag-dispensing mechanism 600 from passing through the a-pocket surface 110 when the bag-dispensing mechanism 600 separates A, B the bag surface 120. When the bag separating mechanism 600 separates the garbage bags, the garbage bags pass through the B vacancy 121 and are connected with the upper side edge part of the B bag surface 120, the A bag surface part 113 can prevent the bag separating mechanism 600 from passing through the A bag surface 110, so that the bag separating mechanism 600 can be reliably connected with the B bag surface 120 at the B vacancy 121, and the A limiting mechanism can limit the A bag surface 110 to move towards the B bag surface 120 in the bag separating process, so that the bag separating mechanism 600 can reliably separate the B bag surface 120 from the A bag surface 110.

Referring to fig. 2 and 5, specifically, the a limiting mechanism is formed by a fixing hole 111 formed on the a bag surface 110, and the a fixing holes 111 are arranged at intervals along the width direction of the a bag surface 110. When the cooperation is automatic to be overlapped bag garbage bin and is used, be provided with on the garbage bin and supply to pass A fixed orifices 111 in order to carry out the about pole 310 that props up with the disposal bag, the tip of about pole 310 sets up limit structure such as dog, and limit structure's such as dog size is greater than A fixed orifices 111 to when minute bag mechanism 600 divides the disposal bag, limit structure such as dog can prevent the A bag face 110 of disposal bag to be close to the removal to B bag face 120 with the cooperation of A fixed orifices 111.

Referring to fig. 1 to 6, after the garbage bag is used and filled with garbage, the garbage bag needs to be taken out from the garbage can, since the a bag surface 110 of the garbage bag is provided with the a fixing hole 111, which forms a limit fit with a limit structure such as a stop block on the restriction rod 310 in the garbage can, so that the garbage bag is inconvenient to take off, in order to solve this problem, in this embodiment, preferably, the periphery of the a fixing hole 111 is provided with the tear mark 112, and when the tear mark 112 is in a tear state, the a bag surface 110 can be separated from the fixing mechanism for fixing the a bag surface 110. Because the tearing mark 112 is arranged on the periphery of the A fixing hole 111, when the A bag surface 110 is taken down, the tearing mark 112 can be torn only by light force, so that the A bag surface 110 can be conveniently slid off and detached from limit structures such as a stop block.

Referring to fig. 1 to 6, the a fixing hole 111 is disposed at the a bag surface 110, and when the a bag surface 110 and the B bag surface 120 are separated, the a fixing hole 111 and the bag dividing mechanism 600 are arranged in a staggered manner. By arranging the a fixing hole 111 and the bag dividing mechanism 600 in a staggered manner, the bag dividing mechanism 600 can be prevented from interfering with a structure for limiting the movement of the a fixing hole 111 on the fixing mechanism, so that the bag dividing mechanism 600 can be reliably connected with the B connecting mechanism on the B bag surface 120.

Further, the position of the a fixing hole 111 is higher than the height of the upper side portion of the B bag surface 120 at the B space. Therefore, the upper side part of the bag face B120 at the vacancy B is conveniently poked with a notch, and then is connected with the upper side part of the bag face B120 at the vacancy B through the bag separating mechanism 600; if the position of the a fixing hole 111 is lower than the height of the upper side portion of the bag B surface 120 at the B vacancy, a problem occurs in the bag dividing process, because before the bag dividing process, it is usually necessary to first open a notch at the upper portion of the garbage bag, then position-limit the bag a surface 110, and then move the bag B surface 120. The opening of the upper portion of the garbage bag may be performed by blowing air, and the blowing direction is generally directed obliquely downward toward the bag surface a 110, and if the position of the fixing hole a 111 is lower than the height of the upper side portion of the bag surface B120 at the gap B, the air flow is easily flowed away from the fixing hole a 111, and compared with the case where the position of the fixing hole a 111 is set higher than the height of the upper side portion of the bag surface B120 at the gap B, the opening of the upper portion of the bag body 100 by blowing air cannot be reliably performed.

In order to save space occupied by the bag surfaces 130 and 140 of the bag C and the bag D on the garbage can in the unfolded state of the bag body 100, the bag surfaces 140 of C, D are arranged between the bag surfaces 120 of A, B in a folded mode.

Referring to fig. 7 to 15, if the garbage bag is applied to the garbage can with automatic bagging, the garbage can needs to adopt a fixing mechanism for fixing the garbage bag of the garbage can with automatic bagging, which is mainly used for assembling the garbage bag in the garbage can.
