Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present invention will be described in detail below with reference to the accompanying drawings. Figures 1 to 3 shown.

[0039] Example 1: See Figure 1 , Figure 2 A garbage bag fusing mechanism, comprising: a main clamping block 1, a secondary clamping block 2 and a driving mechanism, the driving mechanism is used to drive the main clamping block 1 and the secondary clamping block 2 to clamp or open; the main clamping block 1 and / or the secondary clamping block 2 are provided with a heating device, the heating device is used to heat the garbage bag; The lower ends of the main clamping block 1 and / or the auxiliary clamping block 2 are respectively connected with shrinkage pieces for squeezing the two sides of the garbage bag toward the middle; when the driving mechanism drives the main clamping block 1 and the auxiliary clamping block 2 to clamp, the shrinkage pieces push the two sides of the garbage belt to the middle, the main clamping block 1 and the auxiliary clamping block 2 clamp the garbage belt, and the heating device heats the clamped part of the garbage belt and melts it from the middle.

[0040] When the technical solution is implemented, it is installed in a trash can; when the trash can collects garbage, the main clamp block 1 and the auxiliary clamp block 2 are in an open clamp state, and the garbage bag passes through the gap between the main clamp block 1 and the auxiliary clamp block 2. When the garbage bag needs to be sealed, the driving mechanism drives the main clamp block 1 and the auxiliary clamp block 2 to clamp together, and the shrinking plate squeezes the two sides of the garbage bag toward the middle, so that the upper end of the garbage bag is shrunken and located between the main clamp block 1 and the auxiliary clamp block 2. Then the heating device heats the main clamp block 1 and / or the auxiliary clamp block 2, and the temperature of the main clamp block 1 and the auxiliary clamp block 2 rises rapidly, and the garbage bag is melted. When the garbage bag is melted, the upper end of the garbage bag part located below is sealed to seal the garbage inside; the lower end of the garbage bag part located above is sealed to form a new garbage bag.

[0041] It can be understood that when the driving mechanism drives the main clamping block 1 and the auxiliary clamping block 2 to close or open the clamping block, the driving mechanism can only drive one of the main clamping block 1 and the auxiliary clamping block 2 to move, while the other one remains in the same position; the driving mechanism can also drive the main clamping block 1 and the auxiliary clamping block 2 to move at the same time, such as using a clamping finger cylinder. In this embodiment, it is preferred to drive the main clamping block 1 and the auxiliary clamping block 2 to move at the same time. In this embodiment, the driving mechanism is connected to the main clamping block 1 and the auxiliary clamping block 2 respectively, and the main clamping block 1 and the auxiliary clamping block 2 are driven to move at the same time.

[0042] Secondly, the heating device can be separately arranged on the main clamping block 1 or the auxiliary clamping block 2, or can be arranged on both the main clamping block 1 and the auxiliary clamping block 2.

[0043] Similarly, when the shrinking piece is provided, it can be provided on only one of the main clamping block 1 and the auxiliary clamping block 2, or it can be provided on both the main clamping block 1 and the auxiliary clamping block 2.

[0044] See also Figure 4 , Figure 5 , Figure 6 At least one of the two sides of the main clamp block 1 and the auxiliary clamp block 2 is connected to a guide member, and the main clamp block 1 and the auxiliary clamp block 2 can move along the guide member respectively; the driving mechanism includes a main ring 6 and a power device 7 for driving the main ring 6 to rotate, the main ring 6 is located above the main clamp block 1 and the auxiliary clamp block 2, and the two ends of the main ring 6 extend to the main clamp block 1 and the auxiliary clamp block 2 respectively. Main driving rods 61 (see Fig.12 ), the main clamping block 1 and the auxiliary clamping block 2 are respectively provided with a main moving groove 11 matched with the main driving rod 61, and the main driving rod 61 extends into the corresponding main moving groove 11; when the power device 7 drives the main ring 6 to rotate, the main driving rods 61 at both ends of the main ring 6 move along the main moving groove 11 and drive the main clamping block 1 and the auxiliary clamping block 2 to move along the guide rod 8, and the main clamping block 1 and the auxiliary clamping block 2 are clamped or opened.

[0045] The present technical solution combines the use of garbage bags, and adopts the main ring 6 to drive the main clamping block 1 and the auxiliary clamping block 2; when in use, the garbage bag passes through the main ring 6, and the movement of the main ring 6 has no effect or little effect on the garbage bag; the main ring 6 is driven to rotate (self-rotate) by the power device 7, and when the main ring 6 rotates, the main driving rods 61 at both ends thereof also move toward the middle with the main ring 6, and at the same time, the main driving rods 61 move in the corresponding main moving groove 11, and the two main driving rods 61 respectively drive the main clamping block 1 and the auxiliary clamping block 2 to move toward the middle along the guide rod 8; the shrinking piece at the lower end of the main clamping block 1 and the shrinking piece at the lower end of the auxiliary clamping block 2 also move toward each other at the same time, and the two shrinking pieces squeeze the garbage bag from the four end corners to the middle; the upper end of the garbage bag is gradually shrunken, and finally clamped by the main clamping block 1 and the auxiliary clamping block 2, and then heated and melted from the middle.

[0046] Secondly, it can be understood that: in order to facilitate the directional movement of the main clamp block 1 and the auxiliary clamp block 2, the technical solution is provided with a guide member, and the guide member cannot affect the garbage bag in the middle, so it is necessary to set the guide member on the outside of the garbage bag passing space. In this embodiment, the guide member is set on both sides of the main clamp block 1 and the auxiliary clamp block 2, and of course it can also be set on one side; the guide member is used to guide the directional movement of the main clamp block 1 and the auxiliary clamp block 2; the guide member can be a guide rail, etc. In this embodiment, the guide member is two parallel guide rods 8, the main clamp block 1 and the auxiliary clamp block 2 are respectively provided with guide holes that match the guide rods 8, and the main clamp block 1 and the auxiliary clamp block 2 are respectively connected with the guide rods 8. When the main clamp block 1 and the auxiliary clamp block 2 are pushed by the main driving rod 61, the main clamp block 1 and the auxiliary clamp block 2 will move toward or away from each other along the guide rods 8 on both sides, thereby achieving closing or opening of the clamp.

[0047] See also Figure 4 , Figure 5 as well as Figure 7 The driving mechanism also includes a secondary ring 3, and the power device 7 is drivingly connected to the secondary ring 3 and drives the secondary ring 3 to rotate. The secondary ring 3 rotates in the opposite direction to the main ring 6. The secondary ring 3 is located above or below the main ring 6. The two ends of the secondary ring 3 are respectively extended with secondary driving rods 31 toward the main clamping block 1 and the secondary clamping block 2. The main clamping block 1 and the secondary clamping block 2 are respectively provided with secondary moving grooves 12 matched with the secondary driving rods 31. The secondary driving rods 31 extend into the corresponding secondary moving grooves 12, and the secondary moving grooves 12 are adjacent to the main moving grooves 11.

[0048] When a main ring 6 is used, when the power device 7 drives the main ring 6 to rotate, the main driving rod 61 rotates along the main ring 6, the main driving rod 61 will abut against the side wall of the main moving groove 11, and pressure is formed between the main driving rod 61 and the side wall of the main moving groove 11. The pressure can be decomposed into two directions of force, one of which is perpendicular to the side wall and parallel to the direction of the guide rod 8, and the other is parallel to the side wall; since the main clamping block 1 and the auxiliary clamping block 2 both move along the direction of the guide rod 8; the other The component force will be offset by the friction between the main clamp block 1, the auxiliary clamp block 2 and the guide rod 8, thereby causing wear between the main clamp block 1, the auxiliary clamp block 2 and the guide rod 8. After long-term use, the guide hole diameter of the guide rod 8 will continue to increase, which will affect the stability of the movement of the main clamp block 1 and the auxiliary clamp block 2. To avoid this situation, the technical solution provides a secondary ring 3, which is arranged above and below the main ring 6. It can be understood that the secondary ring 3 can be arranged above the main ring 6 or below the main ring 6. In this embodiment, the secondary ring 3 is arranged below the main ring 6.

[0049] Secondly, the secondary ring 3 and the main ring 6 rotate in opposite directions. Therefore, when the driving device drives the secondary ring 3 and the main ring 6 to rotate, in the direction perpendicular to the main movable groove 11, the movement directions of the main driving rod 61 and the secondary driving rod 31 are the same; in the direction parallel to the main movable groove 11, the movement directions of the main driving rod 61 and the secondary driving rod 31 on the same side are opposite; the pressure of the main driving rod 61 on the main movable groove 11 forms a component force N1 in the length direction of the main movable groove 11, and the pressure of the secondary driving rod 31 on the secondary movable groove 12 forms a component force N2 in the length direction of the secondary movable groove 12. The directions of the component force N1 and the component force N2 are opposite and cancel each other out, thereby avoiding the lateral extrusion of the main clamping block 1 and the secondary clamping block 2 on the guide rod 8 caused by the component force N1 and the component force N2, which leads to increased wear.

[0050] Secondly, the lower ends of the main driving rod 61 and the auxiliary driving rod 31 are both connected with a rotating member, and the rotating member can rotate relative to the main driving rod 61 or the auxiliary driving rod 31 .

[0051] The rotating part can be a roller, a bearing or a ball; after adopting the rotating part, the main driving rod 61 or the auxiliary driving rod 31 will not directly abut against the side walls of the corresponding main movable groove 11 and the auxiliary movable groove 12, but will abut against the corresponding side walls through the rotating part. When the main driving rod 61 and the auxiliary driving rod 31 move relatively, the rotating part moves and rotates relative to the corresponding side wall; thereby, the previous sliding friction is converted into the current rolling friction, which effectively reduces the friction coefficient between the side wall, reduces wear, and extends the service life.

[0052] See also Figure 5 , Figure 7 as well as Figure 8The power device 7 includes a motor 71, which is connected to the main ring 6 and the auxiliary ring 3 through a transmission mechanism. The side of the main ring 6 is provided with a main rack 5 arranged in an arc shape or connected with a main gear, and the side of the auxiliary ring 3 is provided with an auxiliary rack 4 arranged in an arc shape or connected with an auxiliary gear. The transmission mechanism includes a first driven gear 76 and a second driven gear 77. The first driven gear 76 is meshed with the main rack 5 or the main gear, and the second driven gear 77 is meshed with the auxiliary rack 4 or the auxiliary gear.

[0053] In order to facilitate the connection of the transmission mechanism with the main ring 6 and the secondary ring 3 and implement the drive; the technical solution is provided with a rack or gear on the side of the main ring 6 and the secondary ring 3, and the transmission mechanism is provided with a corresponding first driven gear 76 and a second driven gear 77, and the transmission mechanism is connected with the main ring 6 and the secondary ring 3 by meshing; when the first driven gear 76 and the second driven gear 77 are connected with the motor 71, a belt transmission mechanism can be used, such as: the first driven gear 76 is connected with a coaxial first pulley, the second driven gear 77 is connected with a coaxial second pulley, the motor 71 is connected with a third pulley, and the third pulley is connected with the first pulley and the second pulley through a belt, wherein the first pulley and the second pulley are respectively located on the inner side and the outer side of the belt. When the motor 71 drives the third pulley to rotate, the third pulley drives the belt to move, and the belt drives the second pulley and the first pulley to rotate. It can be understood that: the belt transmission mechanism can also be provided with a number of other pulleys. The first pulley and the second pulley are respectively located on both sides of the belt, and the first pulley and the second pulley rotate in opposite directions, so that the first driven gear 76 and the second driven gear 77 rotate in opposite directions. Therefore, the main ring 6 and the secondary ring 3 rotate in opposite directions.

[0054] See also Figure 7 The transmission mechanism also includes a worm wheel 72 and a worm 73 connected to each other, the motor 71 is connected to the worm 73, the worm wheel 72 is coaxially connected to a driving gear 74, the driving gear 74 is meshed with a first driven gear 76, and the driving gear 74 is connected to a second driven gear 77 through an intermediate gear 75.

[0055] This technical solution transmits the power of the motor 71 through the worm wheel 72 and the worm 73, and at the same time performs a reduction transmission; when working, the rotating shaft of the motor 71 drives the worm 73 to rotate, and the worm 73 drives the worm wheel 72 to rotate, and the driving gear 74 coaxially connected to the worm wheel 72 also rotates, and the worm wheel 72 and the driving gear 74 can be connected by a shaft or integrally connected. The driving gear 74 directly drives the first driven gear 76 to rotate, and the driving gear 74 drives the second driven gear 77 to rotate through the intermediate gear 75. The first driven gear 76 and the second driven gear 77 rotate in opposite directions, so the main ring 6 and the secondary ring 3 rotate in opposite directions.

[0056] Secondly, the setting of the worm wheel 72 and the worm 73 can avoid the need for the installation space of the motor 71 to be higher than the transmission mechanism when the motor 71 is set, thereby facilitating the setting of the motor 71 and making rational use of space; at the same time, it can also serve as a speed reduction mechanism.

[0057] See also Fig.14 , Fig.15 , the two sides of the lower end of the main clamping block 1 are respectively connected with the shrinking pieces, which are the main shrinking pieces 13; the middle part of the auxiliary clamping block 2 extends downward to form an extension block 21, and the lower end of the extension block 21 is connected with a connecting piece 25, and a gap 24 is formed between the connecting piece 25 and the auxiliary clamping block 2 for the main shrinking piece 13 to pass through, and the two sides of the connecting piece 25 are respectively connected with the shrinking pieces, which are the auxiliary shrinking pieces 23, and the main shrinking piece 13 is located above the auxiliary shrinking piece 23. The outer end of the main shrinking piece 13 is connected with the main reinforcing block 15, and one end of the main reinforcing block 15 is connected to the main clamping block 1; the outer end of the auxiliary shrinking piece 23 is connected with the auxiliary reinforcing block 26, and one end of the auxiliary reinforcing block 26 is connected to the auxiliary clamping block 2.

[0058] In this embodiment, the main shrinking piece 13 and the auxiliary shrinking piece 23 cooperate to squeeze the parts on both sides of the garbage bag toward the middle. The main shrinking piece 13 and the auxiliary shrinking piece 23 are respectively located on both sides. When the main clamping block 1 and the auxiliary clamping block 2 are clamped, the main shrinking piece 13 and the auxiliary shrinking piece 23 move toward each other and shrink the garbage bag. The inner side of the shrinking piece is clean or arc-shaped. When the inner side abuts against the garbage bag, it gradually squeezes the side of the garbage bag toward the middle. In order to facilitate the relative movement of the main shrinking piece 13 and the auxiliary shrinking piece 23, the technical solution arranges the main shrinking piece 13 above the auxiliary shrinking piece 23, and at the same time arranges a gap 24 for the main shrinking piece 13 to pass through below the auxiliary clamping block 2. When shrinking, the main shrinking piece passes through the gap 24.

[0059] Secondly, the shrinking piece squeezes the garbage bag when shrinking; at the same time, it is also squeezed by the garbage bag. In order to provide strength for the shrinking piece, a main reinforcing block 15 and a secondary reinforcing block 26 are respectively provided at the outer ends of the main shrinking piece 13 and the secondary shrinking piece 23.
