Detailed Implementation

[0034] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0035] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0036] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

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

[0039] Example 1: See Figure 1 , Figure 2 A garbage bag melting mechanism includes: a main clamping block 1 and 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, which 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 to the narrowing plates for squeezing the two sides of the garbage bag towards the middle; when the driving mechanism drives the main clamping block 1 and the auxiliary clamping block 2 to clamp together, the narrowing plates 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] In implementation, this technical solution is installed inside a trash can. When the trash can collects trash, the main clamping block 1 and the auxiliary clamping block 2 are in an open clamping state, and the trash bag passes through the gap between the main clamping block 1 and the auxiliary clamping block 2. When it is necessary to seal the trash bag, the drive mechanism drives the main clamping block 1 and the auxiliary clamping block 2 to close. The shrinking plate squeezes the two sides of the trash bag towards the center, so that the upper end of the trash bag is shrinking and located between the main clamping block 1 and the auxiliary clamping block 2. Then, the heating device heats the main clamping block 1 and / or the auxiliary clamping block 2. The temperature of the main clamping block 1 and the auxiliary clamping block 2 rises rapidly and melts the trash bag. When the trash bag melts, the upper end of the lower part of the trash bag is sealed, sealing the trash inside; the lower end of the upper part of the trash bag is sealed, forming a new trash bag.

[0041] It is understandable that when the drive mechanism drives the main clamping block 1 and the auxiliary clamping block 2 to clamp or open, the drive mechanism can drive only one of the main clamping block 1 and the auxiliary clamping block 2 to move, while the other remains in a fixed position; the drive mechanism can also drive the main clamping block 1 and the auxiliary clamping block 2 to move simultaneously, such as by using a finger-clamping cylinder. In this embodiment, it is preferable to drive the main clamping block 1 and the auxiliary clamping block 2 to move simultaneously. In this embodiment, the drive mechanism is connected to the main clamping block 1 and the auxiliary clamping block 2 respectively, driving the main clamping block 1 and the auxiliary clamping block 2 to move simultaneously.

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

[0043] Similarly, when setting the narrowing piece, it can be set on only one of the main clamping block 1 and the secondary clamping block 2, or it can be set on both the main clamping block 1 and the secondary clamping block 2.

[0044] See Figure 4 , Figure 5 , Figure 6 At least one side of the main clamping block 1 and the auxiliary clamping block 2 is connected to a guide member, and the main clamping block 1 and the auxiliary clamping 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 clamping block 1 and the auxiliary clamping block 2, and the two ends of the main ring 6 extend into the main clamping block 1 and the auxiliary clamping block 2 respectively with main drive rods 61 (see Figure 12 The main clamping block 1 and the auxiliary clamping block 2 are respectively provided with main moving grooves 11 that cooperate with the main drive rod 61. The main drive rod 61 extends into the corresponding main moving groove 11. When the power device 7 drives the main ring 6 to rotate, the main drive rods 61 at both ends of the main ring 6 move along the main moving grooves 11 and drive the main clamping block 1 and the auxiliary clamping block 2 to move along the guide rod 8. The main clamping block 1 and the auxiliary clamping block 2 clamp together or open.

[0045] This technical solution, combined with the use of garbage bags, employs a main ring 6 to drive the main clamping block 1 and the auxiliary clamping block 2. During use, the garbage bag passes through the main ring 6, and the movement of the main ring 6 has little or no impact on the garbage bag. The main ring 6 is driven to rotate by a power device 7. As the main ring 6 rotates, the main drive rods 61 at both ends move towards the center, simultaneously moving within their corresponding main moving slots 11. The two main drive rods 61 drive the main clamping block 1 and the auxiliary clamping block 2 to move towards the center along the guide rod 8. The constricting plates at the lower ends of the main clamping block 1 and the auxiliary clamping block 2 also move towards each other simultaneously, squeezing the garbage bag from its four corners towards the center. The upper end of the garbage bag is gradually constricted, and finally, it is clamped by the main clamping block 1 and the auxiliary clamping block 2 and then heated to melt from the center.

[0046] Secondly, it is understandable that: to facilitate the directional movement of the main clamping block 1 and the auxiliary clamping block 2, this technical solution includes guide members. These guide members must not interfere with the central garbage bag; therefore, they need to be positioned outside the space through which the garbage bag passes. In this embodiment, the guide members are positioned on both sides of the main clamping block 1 and the auxiliary clamping block 2, although they could also be positioned on one side. The guide members are used to guide the directional movement of the main clamping block 1 and the auxiliary clamping block 2. The guide members can be guide rails, etc. In this embodiment, the guide members are two parallel guide rods 8. The main clamping block 1 and the auxiliary clamping block 2 each have guide holes that cooperate with the guide rods 8, and the main clamping block 1 and the auxiliary clamping block 2 are respectively sleeved with the guide rods 8. When the main clamping block 1 and the auxiliary clamping block 2 are pushed by the main drive rod 61, they will move towards or away from each other along the guide rods 8 on both sides, thereby achieving clamping or opening.

[0047] See Figure 4 , Figure 5 as well as Figure 7 The driving mechanism also includes a secondary ring 3. The power unit 7 is driven to the secondary ring 3 and drives the secondary ring 3 to rotate. The rotation direction of the secondary ring 3 is opposite to that of 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 extend into the main clamping block 1 and the secondary clamping block 2 respectively, with secondary driving rods 31. The main clamping block 1 and the secondary clamping block 2 are respectively provided with secondary moving grooves 12 that cooperate with the secondary driving rods 31. The secondary driving rods 31 extend into the corresponding secondary moving grooves 12. The secondary moving grooves 12 are arranged adjacent to the main moving grooves 11.

[0048] When using a main ring 6, when the power device 7 drives the main ring 6 to rotate, and the main drive rod 61 rotates along the main ring 6, the main drive rod 61 will abut against the side wall of the main moving groove 11. Pressure is formed between the main drive rod 61 and the side wall of the main moving groove 11. This pressure can be decomposed into two components: one component is perpendicular to the side wall and parallel to the direction of the guide rod 8, and the other component is parallel to the side wall. Since both the main clamping block 1 and the auxiliary clamping block 2 move along the direction of the guide rod 8, the other component... The force component will cancel out the frictional force between the main clamping block 1, the auxiliary clamping block 2, and the guide rod 8, resulting in wear between the main clamping block 1, the auxiliary clamping block 2, and the guide rod 8. After prolonged use, the guide hole diameter of the guide rod 8 will continue to increase, affecting the stability of the movement of the main clamping block 1 and the auxiliary clamping block 2. To avoid this situation, this technical solution provides an auxiliary ring 3, which is positioned vertically above the main ring 6. It can be understood that the auxiliary ring 3 can be positioned above or below the main ring 6. In this embodiment, the auxiliary ring 3 is positioned below the main ring 6.

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

[0050] Secondly, the lower ends of both the main drive rod 61 and the auxiliary drive rod 31 are connected to rotating parts, which can rotate relative to the main drive rod 61 or the auxiliary drive rod 31.

[0051] The rotating component can be a roller, bearing, or ball. With the rotating component, neither the main drive rod 61 nor the auxiliary drive rod 31 will directly abut against the side wall of the corresponding main moving groove 11 or auxiliary moving groove 12. Instead, they abut against the corresponding side wall through the rotating component. When the main drive rod 61 and the auxiliary drive rod 31 move relative to each other, the rotating component moves relative to the corresponding side wall and rotates. This changes the previous sliding friction into rolling friction, effectively reducing the coefficient of friction with the side wall, reducing wear, and extending service life.

[0052] See Figure 5 , Figure 7 as well as Figure 8The power unit 7 includes a motor 71, which is connected to the main ring 6 and the secondary ring 3 via a transmission mechanism. The main ring 6 has an arc-shaped main rack 5 or is connected to a main gear on its side, and the secondary ring 3 has an arc-shaped secondary rack 4 or is connected to a secondary gear on its side. The transmission mechanism includes a first driven gear 76 and a second driven gear 77. The first driven gear 76 meshes with the main rack 5 or the main gear, and the second driven gear 77 meshes with the secondary rack 4 or the secondary gear.

[0053] To facilitate the connection and driving of the transmission mechanism with the main ring 6 and the auxiliary ring 3, this technical solution provides racks or gears on the sides of the main ring 6 and the auxiliary ring 3. The transmission mechanism also includes a corresponding first driven gear 76 and a second driven gear 77. These gears mesh to connect the transmission mechanism to the main ring 6 and the auxiliary ring 3. When the first driven gear 76 and the second driven gear 77 are connected to the motor 71, they can be driven by a belt drive mechanism. For example, the first driven gear 76 is connected to a coaxial first pulley, and the second driven gear 77 is connected to a coaxial second pulley. The motor 71 is connected to a third pulley, which is connected to the first and second pulleys via a belt. The first and second pulleys are located on the inner and outer sides of the belt, respectively. When the motor 71 drives the third pulley to rotate, the third pulley moves the belt, which in turn drives the second and first pulleys to rotate. It is understood that this belt drive mechanism can also include several other pulleys. The first and second pulleys are located on opposite sides of the belt, and their rotation directions are opposite, thus driving the first driven gear 76 and the second driven gear 77 to rotate in opposite directions. Consequently, the main ring 6 and the auxiliary ring 3 also rotate in opposite directions.

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

[0055] This technical solution transmits power from the motor 71 via a worm gear 72 and a worm 73, while simultaneously performing speed reduction transmission. During operation, the motor 71's shaft drives the worm 73 to rotate, which in turn drives the worm gear 72. The driving gear 74, coaxially connected to the worm gear 72, also rotates. The worm gear 72 and the driving gear 74 can be connected via a shaft or integrally. The driving gear 74 directly drives the first driven gear 76 to rotate, and through an intermediate gear 75, it drives the second driven gear 77 to rotate. 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.

[0056] Secondly, the arrangement of the worm gear 72 and worm 73 can avoid the need for the installation space of the motor 71 to be higher than that of the transmission mechanism, thus facilitating the installation of the motor 71 and making reasonable use of space; at the same time, it can also serve as a speed reduction mechanism.

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

[0058] In this embodiment, the main pinch-opening piece 13 and the secondary pinch-opening piece 23 cooperate to squeeze the two sides of the garbage bag towards the center. The main pinch-opening piece 13 and the secondary pinch-opening piece 23 are located on both sides. When the main clamping block 1 and the secondary clamping block 2 clamp the garbage bag, the main pinch-opening piece 13 and the secondary pinch-opening piece 23 move towards each other and pinch the garbage bag. The inner surface of the pinch-opening piece is clean or arc-shaped. When the inner surface comes into contact with the garbage bag, it gradually squeezes the sides of the garbage bag towards the center. To facilitate the relative movement of the main pinch-opening piece 13 and the secondary pinch-opening piece 23, this technical solution places the main pinch-opening piece 13 above the secondary pinch-opening piece 23, and at the same time, a gap 24 is provided below the secondary clamping block 2 for the main pinch-opening piece 13 to pass through. The main pinch-opening piece passes through the gap 24 when pinching the garbage bag.

[0059] Secondly, the closure sheet compresses the garbage bag during the closure process; at the same time, it is also subjected to the compression of the garbage bag. To provide strength to the closure sheet, a main reinforcing block 15 and a secondary reinforcing block 26 are respectively provided at the outer ends of the main closure sheet 13 and the secondary closure sheet 23.

[0060] See Figure 10 , Figure 11 The lower end of the inner side of the auxiliary clamping block 2 is provided with an installation notch 22, and a sealing strip 9 is provided in the installation notch 22. A middle protrusion 91 that cooperates with the installation notch 22 is provided in the middle of one side of the sealing strip 9. The lower end of the inner side of the main clamping block 1 is provided with a notch 14, and the lower end of the other side of the sealing strip 9 is provided with a lower protrusion 92 that cooperates with the notch 14. The heating device is provided on the upper bottom surface of the notch 14.

[0061] In the specific setup, the heating device uses a heating wire. The main clamping block 1, connected to the heating wire, has an electrical wire mounting hole. The heating wire is connected to an electrical wire and connected to an external power source. During welding, the main clamping block 1 and the auxiliary clamping block 2 move towards each other. The main shrinking piece 13 and the auxiliary shrinking piece 23 squeeze the two sides of the garbage bag towards the center. The main clamping block 1 and the auxiliary clamping block 2 clamp together, and the inner side of the main clamping block 1 abuts against the other side of the sealing strip 9. The cooperation between the sealing strip 9 and the main clamping block 1 forms a lateral Z-shape in the middle of the garbage bag. The clamped part of the garbage bag consists of an upper vertical section, a middle horizontal section, and a lower vertical section. The clamped part is heated, and the middle horizontal section is in contact with the heating wire and has the highest temperature. The middle horizontal section is melted, while the upper and lower vertical sections are welded together. The garbage bag is sealed at the upper and lower vertical sections. When the clamp is opened, the broken part falls off under its own weight.

[0062] See Figure 3 , Figure 4 as well as Figure 5 , Figure 16 It also includes a middle shell 16, with a garbage bag inlet 18 in the middle of the middle shell 16, and a guide tube 17 extending downward from the garbage bag inlet 18. The lower end of the guide tube 17 is fitted inside the upper end of the main ring 6, and the lower end of the inner side of the main ring 6 extends downward to form a lower convex ring 62. The upper end of the secondary ring 3 is fitted outside the lower convex ring 62.

[0063] To facilitate the rotation of the main ring 6 and the secondary ring 3, this technical solution includes a middle shell 16, which is sleeved on the upper inner side of the main ring 6 via a guide cylinder 17. This allows the main ring 6 to rotate around the guide cylinder 17 and thus rotate on its own axis. Similarly, the lower inner side of the main ring 6 extends to form a lower convex ring 62, which is sleeved on the upper end of the secondary ring 3, allowing the secondary ring 3 to rotate on its own axis. In a specific configuration, an annular groove that mates with the lower convex ring 62 can be provided on the upper inner side of the secondary ring 3.

[0064] See Figure 4 , Figure 5 as well as Figure 16 The lower end of the main ring 6 is provided with multiple extension posts, which abut against the inner surface of the secondary ring 3. The extension posts reduce the contact area between the secondary ring 3 and the main ring 6, thus reducing friction between them.

[0065] Furthermore, it also includes a bottom shell 19, which is connected to the middle shell. The bottom shell 19 and the middle shell form an accommodating space to house the main ring 6, the secondary ring 3, the main clamping block 1, the secondary clamping block 2, etc., preventing external interference. The middle shell has connecting ears along its downward edge, and the connecting ears are provided with connecting holes and connected to the guide rod 8, thus fixing the guide rod 8.
