The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1 to 19, a garbage bag packing mechanism according to a preferred embodiment of the present application is disposed on a mounting base 100, the mounting base 100 is provided with a garbage input port 200, the garbage input port 200 has four boundaries, namely a front boundary 201, a rear boundary 202, a left boundary 203, and a right boundary 204, and a hot melt component 300 is disposed at the rear boundary 202 of the garbage input port 200; the disposal bag baling mechanism includes:

the extrusion rod 1 is movably arranged on the mounting base 100, and is arranged opposite to the hot melting assembly 300; that is, the initial position of the pressing rod 1 is set at the front boundary 201 of the garbage chute 200, and the pressing rod 1 can move from front to back to the rear boundary 202 and butt against the hot melt assembly 300.

The furling rod 2 is movably arranged on the mounting base 100, and is crossed with the extrusion rod 1; the initial position of the furling rod 2 in this embodiment is set at the right border 204 of the garbage input port 200, and the furling rod 2 can move from right to left and reach the hot melt assembly 300.

The auxiliary rod 3 is movably arranged on the mounting base 100, and is opposite to the furling rod 2; in this embodiment, the auxiliary rod 3 is rotatably disposed at the junction between the rear boundary 202 and the left boundary 203, and the auxiliary rod 3 can be rotated into and out of the trash inlet 200.

A driving component 4, wherein the driving component 4 is suitable for driving the extrusion rod 1 and/or the gathering rod 2 to move.

As shown in fig. 3 and 4, the pressing rod 1 and the furling rod 2 move towards the inner side of the garbage input port 200 under the driving action of the driving assembly 4, and form a bidirectional furling area defined by the pressing rod 1, the furling rod 2 and the double boundaries (in this case, the rear boundary 202 and the left boundary 203) of the garbage input port 200. As shown in fig. 5 and 6, the extrusion rod 1 and the folding rod 2 continue to move, and the bidirectional folding area gradually decreases until the extrusion rod 1 abuts against the auxiliary rod 3, the extrusion rod 1 pushes the auxiliary rod 3 to move towards the inner side of the garbage throwing port 200, and a three-way folding area defined by a single boundary (in this case, the rear boundary 202) of the extrusion rod 1, the folding rod 2, the auxiliary rod 3 and the garbage throwing port 200 is formed; the extrusion rod 1 and the furling rod 2 move continuously, and the three-way furling area is gradually reduced until the extrusion rod 1 approaches the hot melt assembly 300 to finish sealing.

The key point of the present application is that the auxiliary rod 3 is added on the basis of the existing double-rod crossing structure of the folding rod 2 and the extrusion rod 1, and the folding process of the garbage bag packaging mechanism is divided into two stages, namely a two-way folding stage (in the time period when the extrusion rod 1, the folding rod 2 and the garbage throwing port 200 move in a double boundary to form a two-way folding area) and a three-way folding stage (in the time period when the extrusion rod 1, the folding rod 2 and the auxiliary rod 3 move to form a three-way folding area). In the bidirectional furling stage, the furling rod 2 and the extrusion rod 1 are used as two movable edges, the rear border 202 and the left border 203 are used as two fixed edges, and the movable edges gradually push the garbage bag to one side of the fixed edges to furl; in the three-way folding stage, the folding rod 2, the extrusion rod 1 and the auxiliary rod 3 are used as three movable edges, the rear boundary 202 is used as a fixed edge, and the three movable edges surround the garbage bag to one side of the fixed edge to close the garbage bag.

It is foreseeable that through the setting of three-dimensional district of drawing in, can realize that the disposal bag is more even, stable binding off action, and then guarantee the reliability that the disposal bag sealed. In contrast, as shown in fig. 20, the technical solution adopts a cross structure of two pressing rods, the two pressing rods can close the garbage bag to one corner of the garbage input port 200, and then the garbage bag is sealed, in this process, the path through which the garbage bag at the lower right corner passes is longest, and the garbage bag at the upper left corner remains static, which can cause serious non-uniformity of the closing of the garbage bag, and further cause non-uniformity of the sealing, especially the situation that the garbage bag at the upper left corner is still easy to be unsealed in place, which affects the sealing performance of the whole garbage bag; and the setting of auxiliary rod 3 can be when closing up with the disposal bag in the upper left corner to hot melt subassembly 300 and draw in 2 directions of pole and impel in, form the trend of encircleing, can avoid the disposal bag in the upper left corner not in time to reach hot melt subassembly 300 and take place to seal the condition not in place on the one hand, and on the other hand makes the position of sealing of disposal bag draw close to the centre, and then guarantees the homogeneity and the reliability that the disposal bag card was sealed.

It is worth mentioning that the auxiliary rod 3 of the embodiment does not need to be driven by the driving component 4, but moves along with the extrusion rod 1, and the auxiliary rod has the advantages of simple and compact structure, stable and reliable operation, low requirements on machining and assembling precision, convenience in installation and low cost. In contrast, as shown in fig. 21, a three-pressure-bar surrounding structure is adopted in the technical scheme, and although the structure can overcome the problem of uneven sealing of two pressure bars to a great extent, adding one pressure bar inevitably requires a more complicated driving device, a larger accommodating space, higher assembly precision and the like, so that the garbage bag packaging mechanism has a more complicated structure, greater assembly difficulty and higher manufacturing cost; and the auxiliary rod 3 of this embodiment is used for replacing third depression bar, guaranteeing under simple structure, with low costs the prerequisite, can also realize evenly closing in, the function of sealing.

In addition, the existing garbage bag packaging mechanism with double compression bars is easy to cause the phenomenon of bag clamping. Specifically, as shown in fig. 20, during the folding process, the garbage bag is easily caught in the gap at the intersection E of the two pressing rods, thereby affecting the effect of the further sealing operation. For this reason, the embodiment further improves the folding rod 2, specifically as follows:

as shown in fig. 10, the gathering rod 2 is divided into a first gathering part 21 and a second gathering part 22; as shown in fig. 3 and 4, the bidirectional furling zone comprises a primary furling zone S1 and a secondary furling zone S2 which are gradually reduced, wherein when the extrusion rod 1 and the first furling part 21 intersect in fig. 3, the extrusion rod 1, the first furling part 21, the second furling part 22 and the double boundaries of the garbage input port 200 (in this case, the rear boundary 202 and the left boundary 203) define a primary furling zone S1, and when the extrusion rod 1 and the second furling part 22 intersect in fig. 4, the extrusion rod 1, the second furling part 22 and the double boundaries of the garbage input port 200 (in this case, the rear boundary 202 and the left boundary 203) define a secondary furling zone S2; as shown in fig. 9, the intersection a of the pressing rod 1 and the first gather portion 21 is located outside the intersection B of the pressing rod 1 and the extension line of the second gather portion 22.

The sectional arrangement of the furling rod 2 enables the bidirectional furling stage of the garbage bag packaging mechanism to be subdivided into a furling stage (namely, in the time period that the extrusion rod 1, the first furling part 21, the second furling part 22 and the garbage throwing-in opening 200 move to form a furling zone S1) and a secondary furling stage (in the time period that the extrusion rod 1, the second furling part 22 and the garbage throwing-in opening 200 move to form a secondary furling zone S2), wherein the primary furling stage is a key stage for avoiding bag clamping, and the purpose of preventing the bag clamping is realized mainly due to the following aspects:

(1) as shown in fig. 8, the sectional arrangement of the folding rod 2 actually divides the one-time folding area S1 into a slow folding area S11 and a fast folding area S12 by taking the junction of the first folding part 21 and the second folding part 22 as a boundary, the slow folding area S11 and the fast folding area S12 divide the garbage bags into sections, and part of the garbage bags folded in the slow folding area S11 enter the fast folding area S12 through the guiding of the first folding part 21 under the synchronous action of the pressing rod 1, so that the garbage bags can be effectively reduced or even prevented from being "stuck" under the effects of the sections and the guiding.

(2) As shown in fig. 20, it is expected that the garbage bag is easy to gather and pile up at the intersection E of the two pressing rods during the folding process, and excessive pile-up can cause the garbage bag to be "dragged" into the gap at the intersection E due to friction force, so that the "bag clamping" occurs; in contrast, as shown in fig. 9, the intersection a of the pressing rod 1 and the first furling part 21, the intersection B of the pressing rod 1 and the extension line of the second furling part 22, and the intersection C of the first furling part 21 and the second furling part 22 of the present embodiment form a triangular concession cavity T, and the presence of the concession cavity T allows a garbage bag to have a larger receding space, reduces the accumulation of the garbage bag at a, and thus effectively reduces or even avoids the garbage bag "jamming".

(3) As shown in fig. 20, when the linear movement speeds of the two pressing rods are the same or in a linear relationship, the movement locus N of the intersection E of the two pressing rods is a linear path, and the movement speed of the intersection E in the middle period can be regarded as constant, that is, the intersection E has the characteristic of constant diameter and constant speed, when a small part of the garbage bags enter the gap of the intersection E, a larger part of the garbage bags are "dragged" into the gap along the inherent path and speed of the point E, resulting in serious "bag jamming"; in contrast, as shown in fig. 19, when the moving speeds of the pressing rod 1 and the second closing part 22 are the same or in a linear relationship in this embodiment, the moving locus M1 of the intersection a of the pressing rod 1 and the first closing part 21 is a non-linear path, and the moving speed of the intersection a in the intermediate period is constantly changed, i.e. the intersection a has the characteristic of variable diameter and variable speed, even if a small part of the garbage bags enter the gap of the intersection a, due to the constantly changing path and speed of the point a, the garbage bags of other parts are not easy to enter the gap of the intersection a according to a certain rule, and a small part of the garbage bags originally entering the gap of the intersection a can be "pulled" out of the gap, thereby effectively reducing or even avoiding the garbage bags from being "jammed". Incidentally, as shown in fig. 19, in the second folding stage and later, the movement locus M2 of the intersection point D of the pressing rod 1 and the second folding part 22 is also a linear path, but at this time, the garbage bag is basically folded and gradually starts to close, and will not be described in detail.

It should be noted that the folding rod 2 arranged in segments in this embodiment has the effect of reducing or even avoiding the bag jamming of the garbage bag, which is demonstrated by multiple computer simulation and physical comparison tests, and the reasons for achieving the effect include, but are not limited to, the three points described above.

As can be seen from the perspective views of fig. 1, 10 and 11, the first folding portion 21 and the second folding portion 22 are separately arranged, the second folding portion 22 is suitable for linear movement, one end of the first folding portion 21 is movably connected to the mounting base 100, the other end of the first folding portion 21 is movably connected to the second folding portion 22, the second folding portion 22 is suitable for driving the first folding portion 21 to move, and the first folding portion 21 has a certain and unique movement track. Further specifically, the driving assembly 4 is connected to one end of the second folding portion 22, the other end of the second folding portion 22 is hinged to one end of the first folding portion 21, the other end of the first folding portion 21 is provided with a waist-shaped hole 21a, and the mounting base 100 is fixedly provided with a limiting shaft 101 adapted to the waist-shaped hole 21 a.

As shown in fig. 15 and 16, the first furled portion 21 includes an extension section 211 and an action section 212 rigidly connected, the extension section 211 is movably connected to the mounting base 100, and the action section 212 is movably connected to the second furled portion 22, wherein an included angle β between the extension section 211 and the action section 212 is greater than 90 ° and smaller than 180 °, and β is 135 ° in this embodiment. The bending structure of the first furling part 21 mainly takes the problems of space layout and motion path into consideration; specifically, in the initial stage, the first closing part 21 and the second closing part 22 cannot intrude into the garbage input port 200, and in the first closing stage, the first closing part 21 and the second closing part 22 should meet the requirement of not "sticking" the moving path, and considering the above two points together, it is a preferable scheme that the first closing part 21 adopts a bent structure.

As shown in fig. 2 and fig. 9, also considering the spatial layout and the motion path, the included angle α between the action section 212 and the second furled part 22 is greater than 90 °, and during the packing process, the included angle α between the action section 212 and the second furled part 22 gradually decreases, wherein the initial angle of the included angle α between the action section 212 and the second furled part 22 is 180 °, and the second furled part 22 is perpendicular to the pressing rod 1.

Preferably, the pressing rod 1 is adapted to move linearly, and the moving speed of the pressing rod 1 is greater than the moving speed of the second gather portion 22. The folding rod 2 folds the garbage bags at a slow running speed, so that the garbage bags can be folded more smoothly, the extrusion of the extrusion rod 1 is facilitated, and the folding and packing effects are better.

The auxiliary rod 3 is movably connected to the mounting base 100, the movable connection includes but is not limited to sliding connection, rotational connection, and compound movement connection, but preferably, the auxiliary rod 3 is rotatably connected to the mounting base 100 (i.e. hinged), the hinge has the advantages of simple structure, stable operation, and low cost, and a reset member 5 is further disposed between the auxiliary rod 3 and the mounting base 100, and the reset member 5 forces the auxiliary rod 3 to rotate toward the outside of the garbage input port 200.
