[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0028] In this embodiment, as Figures 1 to 4 As shown, the sealing device is used to seal packaging bags. The sealing device includes: a base 1, a turntable 2, a sewing device, a support member, and a flipping member 6. The turntable 2 is rotatably mounted on the base 1. The sewing device is fixedly mounted on the base 1 and located on one side of the turntable 2. The support member is fixedly mounted on the turntable 2 and supports the packaging bag. The turntable 2 rotates to rotate the support member, which rotates to have a sealing position below the sewing device and a filling position on one side of the sewing device. The flipping member 6 is flipped to the upper end of the support member, and flips to have a closed state near a first side of the support member and an open state near a second side of the support member, with the first and second sides of the support member opposite each other. When the flipping member 6 is in the closed state, the opening of the packaging bag is restricted between the flipping member 6 and the first side of the support member, allowing the opening of the packaging bag to close. When the flipping member 6 is in the open state, the opening of the packaging bag overlaps the upper end of the support member.

[0029] In this way, when the turntable 2 is in the loading position, the packaging bag on the support can receive the damaged electricity meter output from the meter breaking machine. At this time, the support is located on one side of the sewing device, which reduces interference. When the flipping part 6 is in the open state, the opening of the packaging bag can be opened so that the damaged electricity meter can enter the packaging bag. After the damaged electricity meter enters the packaging bag, the flipping part 6 switches from the open state to the closed state, so that the opening of the packaging bag can be closed by the flipping part 6, so as to facilitate subsequent sewing operations. Then, the turntable 2 is switched to the sealing position, so that the packaging bag on the support is located below the sewing device, and the sewing device can sew the opening of the closed packaging bag for transportation. In this way, through the setting of the support, flipping part 6, turntable 2 and sewing device, the opening of the packaging bag can be automatically sewn, avoiding manual sewing, simplifying the operation and improving the sealing efficiency. Therefore, the technical solution of this embodiment effectively solves the problem of the cumbersome operation of manually sewing the opening of the packaging bag in related technologies.

[0030] like Figures 1 to 5 As shown, the support includes two opposing upright plates 3 and a support ring 4 connected to the top of the two upright plates 3. A flipping element 6 is flipped and disposed on the upper surface of the support ring 4. This structure can stably support the packaging bag, ensuring accurate positioning of the packaging bag during the sealing process and when the meter enters the packaging bag, thus improving the sealing quality. The support ring 4 can support the opening of the packaging bag. The packaging bag can be accommodated between the two opposing upright plates 3 or removed from between the two opposing upright plates 3. The support has a simple structure and is easy to manufacture.

[0031] like Figures 1 to 5As shown, the sealing device also includes a fixing ring 5 fixedly disposed on the upper surface of the support ring 4. When the flipping member 6 is in the closed state, the opening of the packaging bag is restricted between the flipping member 6 and the fixing ring 5. The flipping member 6 is provided with a first clearance hole 8 penetrating through two opposing surfaces of the flipping member 6 and a plurality of first positioning protrusions 7. The first positioning protrusions 7 are provided to position the opening of the packaging bag so that the opening of the packaging bag can be more reliably placed on the support ring 4. The first clearance hole 8 is provided to prevent the needle of the sewing device from passing through, so as to facilitate the sewing of the opening of the packaging bag by the sewing device. The fixing ring 5 is provided with a second clearance hole penetrating through two opposing surfaces of the fixing ring 5 and a plurality of second positioning protrusions. The second positioning protrusions are provided to position the opening of the packaging bag so that the opening of the packaging bag can be more reliably placed on the support ring 4. The second clearance hole is provided to prevent the needle of the sewing device from passing through, so as to facilitate the sewing of the opening of the packaging bag by the sewing device. By setting the first and second clearance holes, the needle and sewing thread can be prevented from being blocked. At the same time, the first and second positioning protrusions can better position the opening of the packaging bag, ensuring the accuracy and firmness of the seal.

[0032] In this embodiment, the fixing ring 5 is provided with a first circular hole 30 that can accommodate the first positioning protrusion 7. The flipping member 6 is provided with a second circular hole that can accommodate the second positioning protrusion. Thus, when the flipping member 6 is switched to the closed state, the first positioning protrusion 7 can extend into the first circular hole 30, and the second positioning protrusion can extend into the second circular hole, so that the connection between the flipping member 6 and the fixing ring 5 is more reliable when they are closed, so as to reliably close the opening of the packaging bag.

[0033] In other embodiments, the sealing device further includes a fixing ring 5 fixedly disposed on the upper surface of the support ring 4. When the flipping member 6 is in the closed state, the opening of the packaging bag is restricted between the flipping member 6 and the fixing ring 5. The flipping member 6 is provided with a first clearance hole 8 penetrating through two opposing surfaces of the flipping member 6 and a plurality of first positioning protrusions 7. Alternatively, the fixing ring 5 is provided with a second clearance hole penetrating through two opposing surfaces of the fixing ring 5 and a plurality of second positioning protrusions.

[0034] like Figures 1 to 5As shown, the sealing device also includes a connecting rod 9 connected to the flipping component 6, a first gear 12 connected to the connecting rod 9, and a support shaft 11 disposed on the support ring 4. The support shaft 11 is connected to the first gear 12 and spaced apart from the connecting rod 9. The support ring 4 is provided with a through hole 10, and the first gear 12 is rotatably disposed on the outside of the support ring 4. The connecting rod 9 passes through the through hole 10, and the rotation of the first gear 12 drives the flipping component 6 to flip via the connecting rod 9. Thus, when the first gear 12 rotates, it can drive the connecting rod 9 to swing around the support shaft 11, thereby driving the flipping component 6 to flip, so that the flipping component 6 can switch between a closed state and an open state. The through hole 10 can prevent the swinging of the connecting rod 9. This structure can smoothly control the flipping of the flipping component 6, improving the stability and service life of the equipment.

[0035] In this embodiment, the via 10 is an arc-shaped elongated hole.

[0036] like Figures 1 to 5 As shown, the sealing device also includes a first telescopic rod 13 and a rack 14 meshing with a first gear 12. The first cylinder of the first telescopic rod 13 is fixedly mounted on the vertical plate 3, and the first piston rod of the first telescopic rod 13 is telescopically mounted within the first cylinder. The rack 14 is fixedly connected to the first piston rod; the extension and retraction of the first piston rod drives the rack 14 to move, and the movement of the rack 14 drives the first gear 12 to rotate. Thus, when the first piston rod extends and retracts within the first cylinder, it can drive the rack 14 to move, thereby driving the first gear 12 to rotate, which in turn causes the flipping component 6 to flip. The above configuration is simple in structure and reliable in transmission. Through the cooperation of the first telescopic rod 13 and the rack 14, the automatic flipping of the flipping component 6 can be achieved, improving the automation level of the sealing device.

[0037] like Figures 1 to 5 As shown, the sealing device also includes a fixed plate 16 fixedly mounted on the vertical plate 3 and a slide rod 15 fixedly connected to the rack 14. The fixed plate 16 has a first guide hole, and the slide rod 15 passes through and guides the rack 14 within the first guide hole. Thus, when the first piston rod drives the rack 14 to move, the slide rod 15 can move relative to the fixed plate 16, and the guide engagement of the slide rod 15 with the first guide hole makes the movement of the rack 14 more stable and reliable. This structure ensures the smooth movement of the rack 14, improving the stability and accuracy of the sealing device.

[0038] like Figures 1 to 5As shown, the sealing device also includes a first motor 18 fixedly mounted on a base 1, a gearbox 19 driven by the first motor 18, a second gear 17 rotatably mounted on the base 1, and a third gear 20 rotatably mounted on the base 1. The third gear 20 is driven by the gearbox 19, the second gear 17 meshes with the third gear 20, and the second gear 17 is fixedly connected to the turntable 2. The first motor 18 drives the third gear 20 to rotate via the gearbox 19, which in turn drives the turntable 2 to rotate via the second gear 17. The gearbox 19 can adjust the rotational speed of the third gear 20, thereby controlling the rotational speed of the turntable 2. Through the cooperation of the first motor 18, the second gear 17, and the third gear 20, precise rotation of the turntable 2 can be achieved, improving the automation level and accuracy of the equipment. The above configuration is reliable in transmission and simple in structure.

[0039] like Figures 1 to 5 As shown, the sewing device includes a mounting plate 21 fixedly connected to a base 1 and a sewing machine 23 movably mounted on the mounting plate 21. The sewing machine 23 moves in a horizontal plane with a first moving direction and a second moving direction, forming an angle between the first and second moving directions. This design enables the sewing machine 23 to move in both directions, achieving reliable sewing of the opening of the packaging bag and improving the sealing strength.

[0040] like Figures 1 to 5 As shown, the sealing device also includes a second telescopic rod 24 mounted on the mounting plate 21, with its second cylinder fixedly mounted on the mounting plate 21. The second piston rod of the second telescopic rod 24 is telescopically mounted within the second cylinder along a first moving direction, passing through the mounting plate 21 and fixedly connected to the sewing machine 23. Thus, when the second piston rod extends or retracts within the second cylinder, it drives the sewing machine 23 to move relative to the mounting plate 21 along the first moving direction. The second telescopic rod 24 has a simple structure, facilitating processing and assembly. The mounting plate 21 has a second guide hole, and the sealing device also includes a guide rod 25 fixedly connected to the sewing machine 23. The guide rod 25 is movably inserted into the second guide hole and guides the sewing machine 23 accordingly. When the second piston rod drives the sewing machine 23 relative to the mounting plate 21, the guide rod 25 moves within the second guide hole, and the guide rod 25 guides the sewing machine 23, making its movement smoother. This structure ensures precise movement of the sewing machine 23 in the first moving direction, improving the accuracy and quality of the sealing.

[0041] like Figures 1 to 5As shown, the sewing device also includes a connecting block 29 fixedly connected to the sewing machine 23, a frame 22 connected to the mounting plate 21, a drive screw 26 rotatably disposed within the frame 22, and a second motor 27 drivenly connected to the drive screw 26. The connecting block 29 has a threaded hole capable of threadedly engaging with the drive screw 26. The axis of the drive screw 26 extends along a second moving direction. The second motor 27 drives the drive screw 26 to rotate, thereby driving the sewing machine 23 to move along the second moving direction via the connecting block 29. Thus, when the drive screw 26 rotates, it can drive the connecting block 29 to move relative to the frame 22 along the second moving direction, thereby driving the sewing machine 23 to move along the second moving direction. The sewing device also includes a limiting rod 28 fixedly disposed on the frame. The connecting block 29 has a third guide hole, and the limiting rod 28 passes through and is guided within the third guide hole. When the connecting block 29 moves relative to the frame 22 along the second moving direction, the connecting block 29 can move relative to the limiting rod 28, and the third guide hole on the connecting block 29 can guide and cooperate with the third guide hole, making the movement of the connecting block 29 and the sewing machine 23 more stable. This design can ensure the precise movement of the sewing machine 23 in the second moving direction. Combined with the control of the first moving direction, it can realize the precise movement of the sewing machine in all directions in the horizontal plane, improving the accuracy and quality of sealing.

[0042] In this embodiment, the frame 22 is fixedly connected to the second piston rod so that the frame 22 can move relative to the mounting plate 21 along a first moving direction. The first moving direction is the diameter direction of the turntable 2.

[0043] The inventors discovered that in addition to inspecting newly acquired electrical equipment such as meters and transformers, power supply service centers also need to uniformly dispose of recycled scrapped meters. Scrapped meters require drilling to destroy the internal memory chips to prevent them from being reused and affecting the accuracy of electricity bill deductions. Due to the large volume of old meters being recycled, manual dismantling is limited in speed, resulting in accumulation and space occupation. Therefore, a meter dismantling machine integrating sorting, automatic scanning, and dismantling was specially customized. Existing meter dismantling machines suffer from insufficient equipment compatibility design; the machines cannot automatically bag and seal the dismantled meters. Typically, a person is stationed at the machine's exit to collect the scrapped meters in woven bags. Once a bag is full, the opening is tied with rope or sewn shut and labeled, then piled in a designated location to await centralized transportation for further crushing. This process results in low work efficiency.

[0044] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" 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 utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0045] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0046] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
