Description

Technical Field

[0001] The utility model belongs to the technical field of trash cans, and particularly relates to a motion mechanism and an intelligent trash can that can be reset after being folded up. Background Art

[0002] As a device for temporarily storing garbage, trash cans are essential equipment in daily life. The existing technology is as follows: a motor drives a flexible belt to fold and seal a plastic bag. After the plastic bag is folded and sealed, the motor rotates in reverse to drive the synchronous belt to retreat and reset. However, this mechanism gets stuck due to the motor changing direction, and the motor-driven gear is no longer synchronized with the synchronous belt. The angle of rotation of the motor is inconsistent with the angle of the synchronous belt laying, resulting in the synchronous belt not being reset and getting stuck. To solve the problem of the synchronous belt getting stuck during reset, a new solution and idea are needed.

[0003] For example, Chinese Patent CN111977218A discloses a garbage bag flexible packing mechanism and a trash can, including a mounting plate, a driving device, a bag closing mechanism, and a sealing device arranged on the mounting plate. The mounting plate is provided with a mounting plate through hole, and a flexible belt limiting groove is arranged around the mounting plate through hole on the mounting plate. The driving device includes a motor and a reduction drive gear driven by the motor. The bag closing mechanism includes a flexible belt arranged around the mounting plate through hole. The head end of the flexible belt is fixedly arranged on the mounting plate, the middle part bypasses the sealing end face of the sealing device, and is meshed and connected with the reduction drive gear. The tail end reciprocally moves along the flexible belt limiting groove as the reduction drive gear rotates. The flexible belt has high-temperature resistant insulation characteristics at least at the part in contact with the sealing end face. The driving device and the sealing device are communicably connected to the control device. In this bag sealing and packing mechanism, the reliability of the bag closing mechanism driven by the driving device to reciprocate is poor, and it is easy to get stuck and unable to reset for cyclic packing. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the purpose of the embodiments of the present utility model is to provide a motion mechanism and an intelligent trash can that can be reset after being folded up.

[0005] The technical solution adopted in the embodiment of the present utility model is a motion mechanism that resets after folding, including a lower cover. The lower cover is annular, and a packing and sealing mechanism and a laying mechanism are installed on the lower cover. The packing and sealing mechanism includes a synchronous belt and a first motor gear assembly. One end of the first motor gear assembly and the synchronous belt is fixed on the lower cover, and the first motor gear assembly drives the synchronous belt to tighten / send out. The laying mechanism includes a positioning ring block and a second motor gear assembly. The positioning ring block is coaxially fixed on the inner edge of the lower cover, the second motor gear assembly is installed on the lower cover, a first toothed ring is coaxially sleeved on the positioning ring block, the second motor gear assembly meshes with and drives the first toothed ring, a synchronous release mechanism is installed on the first toothed ring, the synchronous belt is constrained by the synchronous release mechanism, and the synchronous release mechanism follows the first toothed ring to rotate and release the synchronous belt. A positioning rib is installed on the first toothed ring, and a positioner cooperating with the positioning rib is installed on the lower cover. When the synchronous release mechanism rotates 180° to 360° following the first toothed ring starting from the fixed end of the synchronous belt, the positioning rib contacts the positioner, and when the positioner contacts the positioning rib, a signal is sent to make the second motor gear assembly reverse and operate, and the first motor gear assembly stops operating. This technical solution realizes the sealing and packing action through the packing and sealing mechanism and the laying mechanism, achieves the tightening / release in the packing action by folding / sending out the synchronous belt, and the laying mechanism is used to regularize the synchronous belt to prevent the synchronous belt from being unable to reset and jam. Among them, the positioning rib cooperating with the positioner is used to control the synchronous release mechanism to reset after the synchronous belt is laid, so as to be able to perform a cyclic packing action.

[0006] Further, the synchronous release mechanism includes a second toothed ring. The second toothed ring is installed on the lower cover, and the second toothed ring is coaxially arranged with the first toothed ring. A gear set and a pin are installed on the first toothed ring. The gear set meshes with the second toothed ring, and the synchronous belt passes between the gear set and the pin, and the gear set and the pin clamp the synchronous belt to lay the synchronous belt following the rotation of the first toothed ring. The synchronous release mechanism is used to make the rotation angle of the first toothed ring 7 synchronous with the laying angle of the synchronous belt 3.

[0007] Further, the inner edge of the second toothed ring is configured as a toothed part. The toothed part of the second toothed ring meshes with the gear set, and the diameter of the second toothed ring is larger than that of the first toothed ring. The second toothed ring with a toothed inner edge is convenient for installation and can be fixed from the outer edge of the second toothed ring.

[0009] Further, the gear set includes one or more gears, and at least one of the gears meshes with the tooth surface of the synchronous belt. By matching the gear parameters in the gear set, the rotation angle of the first toothed ring can be ensured to be consistent with the laying angle of the synchronous belt.

[0010] Further, a roller is sleeved on the pin. The roller reduces the friction between the synchronous belt and the pin, ensuring the smooth laying of the synchronous belt.

[0011] Further, a cutting and sealing mechanism is further included. The cutting and sealing mechanism is fixed at the inner edge of the lower cover corresponding to the fixed end of the synchronous belt, and the cutting and sealing mechanism is an electric heating block or an electric heating plate.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted in this utility model.

[0031] Refer to Figures 1 to 7, an embodiment of the present utility model provides a motion mechanism that resets after folding, including a lower cover 1. The lower cover 1 is annular. A packing and sealing mechanism and a laying mechanism are installed on the lower cover 1. The packing and sealing mechanism includes a synchronous belt 3 and a first motor gear assembly 4. One end of the first motor gear assembly 4 and the synchronous belt 3 is fixed on the lower cover 1. The first motor gear assembly 4 drives the synchronous belt 3 to tighten / send out. The laying mechanism includes a positioning ring block 5 and a second motor gear assembly 6. The positioning ring block 5 is coaxially fixed on the inner edge of the lower cover 1. The second motor gear assembly 6 is installed on the lower cover 1. A first toothed ring 7 is coaxially sleeved on the positioning ring block 5. The second motor gear assembly 6 meshes with and drives the first toothed ring 7. A synchronous release mechanism is installed on the first toothed ring 7. The synchronous belt 3 is constrained by the synchronous release mechanism. The synchronous release mechanism follows the rotation of the first toothed ring 7 to release the synchronous belt 3. A positioning rib 12 is installed on the first toothed ring 7. A positioner 13 that cooperates with the positioning rib 12 is installed on the lower cover 1. When the synchronous release mechanism follows the first toothed ring 7 to rotate 180° to 360° starting from the fixed end of the synchronous belt 3, the positioning rib 12 contacts the positioner 13. When the positioner 13 contacts the positioning rib 12, a signal is sent to make the second motor gear assembly 6 reverse and operate, and the first motor gear assembly 4 stops operating. This technical solution realizes the sealing and packing action through the packing and sealing mechanism and the laying mechanism. The packing action is achieved by tightening / sending out the synchronous belt. The laying mechanism is used to regularize the synchronous belt to prevent the synchronous belt from getting stuck due to inability to reset. Among them, the positioning rib cooperates with the positioner to control the synchronous release mechanism, and the synchronous release mechanism resets after laying the synchronous belt, so that a cyclic packing action can be achieved. This technical solution can be used in trash cans or packaging machinery. When applied to trash cans, it can realize the sealing and packing of garbage bags in the trash can, and tighten / release the garbage bags by tightening / sending out the synchronous belt. And the synchronous release mechanism cooperating with the positioning rib and positioner can realize the reset of the synchronous release mechanism after laying the synchronous belt, so that a cyclic packing can be achieved.

[0032] The synchronous release mechanism includes a second toothed ring 8. The second toothed ring 8 is installed on the lower cover 1. The second toothed ring 8 is coaxially arranged with the first toothed ring 7. A gear set 9 and a pin 10 are installed on the first toothed ring 7. The gear set 9 meshes with the second toothed ring 8. The synchronous belt 3 passes between the gear set 9 and the pin 10, and the gear set 9 and the pin 10 clamp the synchronous belt 3 to lay the synchronous belt 3 following the rotation of the first toothed ring 7. The synchronous release mechanism is used to make the rotation angle of the first toothed ring 7 synchronous with the laying angle of the synchronous belt 3.

[0033] The inner edge of the second toothed ring 8 is configured as a toothed portion. The toothed portion of the second toothed ring 8 meshes with the gear set 9, and the diameter of the second toothed ring 8 is larger than that of the first toothed ring 7. The second toothed ring 8 with a toothed portion on its inner edge is convenient for installation, which can be fixed from the outer edge of the second toothed ring 8. The outer edge of the second toothed ring 8 can be directly fixedly connected to the lower cover 1.

[0034] The tooth surface for cooperating with the gear set 9 and the first motor gear assembly 4 is provided on the synchronous belt 3. The toothed portion on the synchronous belt 3 is beneficial for its cooperation with the gear set 9 to achieve the synchronization of the rotation angle of the first toothed ring 7 and the laying angle of the synchronous belt 3; and is beneficial for the first motor gear assembly 4 to retract / feed out the synchronous belt 3

[0035] The gear set 9 includes one or more gears, and at least one of the gears meshes with the tooth surface on the synchronous belt 3. The gear parameters in the gear set 9 are coordinated to ensure that the rotation angle of the first toothed ring 7 is consistent with the laying angle of the synchronous belt 3.

[0036] A roller 11 is sleeved on the pin 10. The roller 11 reduces the friction between the synchronous belt 3 and the pin 10 and ensures the smooth laying of the synchronous belt 3.

[0037] It further includes a cutting and sealing mechanism 2, which is fixed at the corresponding position of the inner edge of the lower cover 1 corresponding to the fixed end of the synchronous belt 3. The cutting and sealing mechanism 2 is an electric heating block or an electric heating plate. When the synchronous belt is retracted, it cooperates with the cutting and sealing mechanism 2 to thermally cut the garbage bag, realizing the packing and sealing of the garbage bag.

[0038] Refer to Figure 1 , when working and retracting, the first motor gear assembly 4 works to retract the synchronous belt 3. As shown in the figure, it is retracted into the groove, and then the cutting and sealing mechanism 2 works to generate heat and cut the garbage bag.

[0039] Refer to Figure 1 、 2 and 3. After the garbage bag is thermally cut, the synchronous belt 3 performs a reset movement: the first motor gear assembly 4 feeds out the synchronous belt 3. As shown in the figure, it is fed out of the groove. At the same time, the second motor gear assembly 6 works. The second motor gear assembly 6 drives the first toothed ring 7 to rotate counterclockwise until the positioning rib 12 of the first toothed ring 7 touches the positioner 13. At this time, the first motor gear assembly 4 stops working, and then the second motor gear assembly 6 reverses its operation. The second motor gear assembly 6 drives the first toothed ring 7 to rotate clockwise, and the synchronous release mechanism follows the reverse operation until it returns to the initial position (such as Figure 1 ) to complete the synchronous belt reset action.

[0040] Refer to Figures 1 to 9, the embodiment of the present utility model further provides an intelligent trash can, including a barrel body 14, and a movement mechanism that retracts and then resets as described above is installed at the opening of the barrel body 14. It further includes an upper cover 15, and the upper cover 15 covers the movement mechanism that retracts and then resets.

[0041] The upper cover 15 is annular, and a garbage bag box 16 is installed on the upper cover 15. The garbage bag box 16 is annular, and an annular placement groove 17 is coaxially opened on the garbage bag box 16, and the opening of the annular placement groove 17 faces downward. When in use, a continuous tubular plastic bag can be selected as the garbage bag. The continuous tubular plastic bag is coaxially retracted into the annular placement groove 17, and by using the hot melt cutting of the transmission connection mechanism for synchronously belt-packing and sealing the bag, it can be realized that a section of the garbage bag is hot melt packed after being used for a period.

[0042] The above description is intended to be illustrative rather than restrictive, and those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of their solutions) can be used in combination with each other, and it is considered that these embodiments can be combined with each other in various combinations or arrangements.
