Description

Technical Field

[0001] The utility model belongs to the technical field of garbage collection devices, and in particular relates to a packaging and sealing mechanism with a pressure regulating mechanism and an intelligent garbage can. Background Art

[0002] When packing garbage bags, smart trash cans usually use heating elements to heat-melt seal the garbage bags, heat-sealing the garbage to the inside of the garbage bags, making the placement of garbage bags more convenient.

[0003] However, in conventional packaging and sealing mechanisms, the start and stop of the heating element and the power level are pre-set in the program. Regardless of the packaging conditions, the working state of the heating element is the same. When the garbage bag is not completely packed to a certain point, the heating element will not be fully squeezed, resulting in incomplete sealing. At the same time, excessive squeezing will also cause burns to the packaging and pressing mechanism.

[0004] Therefore, it is necessary to design a packaging and sealing mechanism with a built-in pressure regulating mechanism and apply it to the smart trash can to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The following is a detailed description of specific embodiments to illustrate the overall and partial structural schematic diagram of the packaging and sealing mechanism with a built-in pressure regulating mechanism of the utility model.

[0030] A packaging and sealing mechanism with a pressure regulating mechanism comprises a driving mechanism 1, a rotating shaft 2, a synchronous belt, a connecting rod mechanism, a guide rod, a packaging connecting rod and a packaging pressure rod.

[0031] The driving mechanism 1 is a servo motor, and gears meshing with each other are fixedly sleeved on the output shaft of the servo motor and the middle of the rotating shaft 2. When the servo motor rotates, it drives the rotating shaft 2 to rotate synchronously. The first rotating gear 5 and the second rotating gear 6 are fixedly sleeved on both ends of the rotating shaft 2.

[0032] There are two groups of synchronous belts, guide rods, packing links and packing pressure rods, which are: a first synchronous belt 3 and a second synchronous belt 4 arranged in parallel; a first guide rod 7 arranged in parallel on the outside of the first synchronous belt 3, and a second guide rod 8 arranged in parallel on the outside of the second synchronous belt 4; a first packing link 9 and a second packing link 10 arranged side by side and in parallel on the inner sides of the first synchronous belt 3 and the second synchronous belt 4; the first packing link 9 and the second packing link 10 are both hollow structures, and a first packing pressure rod 11 and a second packing pressure rod 12 are vertically penetrated inside the first packing link 9 and the second packing link 10.

[0033] The first packing connecting rod 9, the second packing connecting rod 10, the first packing pressing rod 11 and the second packing pressing rod 12 together enclose a garbage delivery port.

[0034] A garbage bag sealing mechanism is provided on the second packing pressure rod 12 on one side facing the first packing pressure rod 11 . The garbage bag sealing mechanism includes a base 13 and a thermal resistance wire 14 fixed on the base 13 . A pressure sensor 15 is fixedly installed at each end of the thermal resistance wire 14 .

[0035] The pressure sensor 15 is connected to the MCU, and the MCU is connected to the thermal resistance wire circuit and controls the power of the thermal resistance wire 14 . The MCU receives the pressure signal from the pressure sensor 15 , and then adjusts the power of the power device, thereby controlling the operation of the thermal resistance wire 14 .

[0036] One end of the first synchronous belt 3 is internally meshed and rotatably connected to the outside of the first rotating gear 5 , and one end of the second synchronous belt 4 is internally meshed and rotatably connected to the outside of the second rotating gear 6 .

[0037] A first driven gear 16 is meshed and rotatably connected inside the other end of the first synchronous belt 3 , and a second driven gear 17 is meshed and rotatably connected inside the other end of the second synchronous belt 4 .

[0038] There are four groups of connecting rod mechanisms in total, two groups of connecting rod mechanisms are arranged between the first guide rod 7 and the first packing connecting rod 9, and another two groups of connecting rod mechanisms are arranged between the second guide rod 8 and the second packing connecting rod 10.

[0039] Each set of link mechanisms includes a rotating rod 18 and a sleeve 19. In the two sets of link mechanisms between the first guide rod 7 and the first packing link 9, one end of the rotating rod 18 is rotatably connected to the first packing link 9, and the other end is rotatably connected to the sleeve 19. A through hole is provided at each end of the sleeve 19. The sleeve 19 is movably sleeved on the first guide rod 7 through the through hole, and one end of the first packing pressure rod 11 (or the second packing pressure rod 12) is sleeved on the first guide rod 7 and located between the two sleeved through holes. In these two sets of link mechanisms, the rotating rod 18 of one set is located above the first packing link 9, and the rotating rod 18 of the other set is located below the first packing link 9.

[0040] The connection method of the two sets of connecting rod mechanisms between the second guide rod 8 and the second packing connecting rod 10 is the same as above.

[0041] Working principle: When the packing and sealing mechanism is not started, the garbage delivery port is opened, the first packing link 9 and the second packing link 10 are close to the first synchronous belt 3 and the second synchronous belt 4 respectively, the first packing pressure rod 11 is closest to the rotating shaft 2, and the second packing pressure rod 12 is farthest from the rotating shaft 2, and the end of the first packing pressure rod 11 abuts against the end of the sleeve 19 on the side closest to the rotating shaft 2, and the end of the second packing pressure rod 12 abuts against the end of the other sleeve 19 on the side farthest from the rotating shaft 2.

[0042] When packing begins, the servo motor starts to rotate, and drives the rotating shaft 2 to rotate through the gear transmission, and drives the first synchronous belt 3 and the second synchronous belt 4 to rotate synchronously. Due to the meshing action, the first packing pressure rod 11 and the second packing pressure rod 12 move toward the middle of the garbage delivery port. When the end of the first packing pressure rod 11 moves to the other end of the sleeve 19, the end of the second packing pressure rod 12 moves synchronously to the other end of the other sleeve 19, driving the two sleeves 19 to move toward the middle of the first guide rod 7. At the same time, it will drive the rotating rod 18 to rotate, and drive the first packing link 9 and the second packing link 10 to move toward the middle of the garbage delivery port. The middle part, finally, the first packing link, the second packing link 10, the first packing pressure rod 11 and the second packing pressure rod 12 will be close to each other, and the garbage bags set in the garbage delivery port will be gathered to the center of the garbage delivery port.

[0043] At this time, the pressure sensor 15 senses the pressure and feeds back the pressure value to the MCU. When the pressure of the two pressure sensors 15 at both ends of the thermal resistance wire 14 reaches above the set value, the MCU outputs a signal, adjusts the power, and the thermal resistance wire 14 starts to seal, and stops after the sealing reaches the set time. This ensures that the pressure above the thermal resistance wire 14 is uniform, and the sealing pressure on the garbage bag is consistent, so that the sealing effect of the thermal resistance wire 14 is better, the edge is more beautiful, and uneven sealing is avoided.

[0044] The above are only preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the utility model should be included in the protection scope of the utility model.
