Description

Technical Field

[0001] The invention relates to a garbage can packing device, and in particular to a fully automatic garbage bag packing device and an intelligent garbage can. Background Art

[0002] As people's living standards improve day by day, the pace of life accelerates, and various types of garbage increase, garbage disposal has become an indispensable part of people's lives. Traditional trash cans only have the ability to store garbage, which can no longer meet people's needs.

[0003] In pursuit of a more convenient experience, some smart trash cans have been proposed in the prior art. For example, the invention application with application publication number CN 108584238 A discloses a garbage bag packing mechanism and a smart trash can, and the utility model patent with authorization announcement number CN 210012170 U discloses a garbage bag packing mechanism and a smart trash can. The above two types of trash cans can automatically open or close the garbage delivery port before and after the garbage is put in, and when the garbage in the garbage bag reaches a certain amount, it can also automatically pack and change bags, which greatly facilitates people's garbage disposal.

[0004] However, after the above-mentioned smart trash can is folded, the trash bag is sealed by heating and melting. This will cause the following problems: since the trash bag is very soft, it is loaded into the trash can. In addition, the shape of the collected trash is irregular, the posture of the trash bag is unpredictable, and overlapping and folding often occur. In addition, in the process of folding, the folded parts may gradually accumulate and thicken, making the final folded shape of the trash bag uneven, that is, the melting surface is unbalanced. This may cause the parts of the trash bag that are too thin to not be melted, and the parts that are too thick to be not melted sufficiently, so that a qualified sealing effect cannot be obtained, the sealing is not high, it is easy to leak, and the use quality is poor. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a fully automatic garbage bag packing device, which adopts a new sealing method and will not be affected by the final folded shape of the garbage bag. It can obtain a stable and qualified sealing effect and has the advantages of good sealing quality, high sealing, and not easy to leak.

[0006] Another object of the present invention is to provide a smart trash can.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A fully automatic garbage bag packaging device, comprising a folding mechanism for folding the unfolded garbage bags, a bundling mechanism for bundling the folded garbage bags, and a separating mechanism for cutting and separating the bundled and sealed garbage bags;

[0009] The folding mechanism is arranged at the upper part of the garbage bin, and comprises a folding rod and a folding driving mechanism, wherein the folding rod comprises a first folding rod and a second folding rod, and the first folding rod and the second folding rod are arranged perpendicularly to each other on both sides of the garbage bag delivery port; the folding driving mechanism drives the first folding rod to perform preliminary folding of the unfolded garbage bag, and the folding driving mechanism drives the second folding rod to fold the preliminary folded garbage bag again into the bundling station of the bundling mechanism; the bundling station is arranged on the side of the garbage bag delivery port opposite to the second folding rod;

[0010] The bundling mechanism is provided with two groups, which are used to bundle the upper opening of the garbage bag currently loaded with garbage and the lower opening of the next garbage bag respectively; the bundling mechanism comprises bundling nails for bundling the garbage bags, a bundling feeding mechanism for feeding the bundling nails, and a bundling forming mechanism for bundling the bundling nails on the garbage bags located in the bundling station; the bundling nails of the two groups of bundling mechanisms are respectively located on both sides of the bundling station, and the openings of the bundling nails are all facing the garbage bags; wherein the bundling nails used to bundle the upper opening of the garbage bag currently loaded with garbage are located at a position lower than the bundling nails used to bundle the lower opening of the next garbage bag;

[0011] The separation mechanism separates the integrated garbage bags between the upper opening binding nail of the garbage bag loaded with garbage and the lower opening binding nail of the next garbage bag.

[0012] The working principle of the above-mentioned fully automatic garbage bag packaging device is:

[0013] When the garbage in the garbage bag reaches a certain amount, the packaging work begins. The folding drive mechanism first drives the first folding rod to initially fold the unfolded garbage bag, and then drives the second folding rod to fold the initially folded garbage bag again into the bundling station, and then carries out the bundling work.

[0014] Prior to this, the two groups of bundling feeding mechanisms respectively transport the two bundling nails to the predetermined positions (the openings of the two bundling nails are both facing the garbage bag), wherein the two bundling nails are located at two different heights. Then, the two groups of bundling forming mechanisms respectively bundle the corresponding bundling nails on the garbage bag, and the two bundling nails located at different heights firmly pack and press the garbage bag, and respectively seal the upper opening of the garbage bag currently loaded with garbage and the lower opening of the next garbage bag. At this time, the straight-through garbage bag forms a three-section structure, and then the separation mechanism of the garbage bin divides the garbage bag at the position between the two bundling nails, so that one garbage bag is separated into two, the lower one is a completely sealed used garbage bag, and the upper one is a standby garbage bag ready for storing garbage, thereby completing the packaging work, and when the user takes the used garbage bag out of the garbage bin, garbage collection can be started again.

[0015] In a preferred embodiment of the present invention, there are two first gathering rods, which are respectively arranged on two opposite sides of the garbage bag delivery port; and there is one second gathering rod, which is arranged on the side of the garbage bag delivery port opposite to the bundling station. Through the above structure, the gathering drive mechanism can first drive the two first gathering rods to initially gather the garbage bags to the middle of the garbage bag delivery port, and then drive the second gathering rod to gather the initially gathered garbage bags to the bundling station. In this way, the bundling station can be arranged in the middle of the side of the garbage bag delivery port, which is beneficial to the structural arrangement of the bundling mechanism.

[0016] In a preferred embodiment of the present invention, the folding drive mechanism comprises a first folding drive mechanism for driving the first folding rod to move and a second folding drive mechanism for driving the second folding rod to move, and the driving direction of the first folding drive mechanism is perpendicular to the driving direction of the second folding drive mechanism;

[0017] The first folding rod is connected to a driving end of a first folding driving mechanism, and the second folding rod is connected to a driving end of a second folding driving mechanism.

[0018] Preferably, the first folding drive mechanism includes a first folding drive motor and a first folding transmission assembly, the first folding drive motor is fixed on the frame, the first folding transmission assembly includes a first screw transmission assembly, the screw of the first screw transmission assembly is parallel to the second folding rod; one end of the first folding rod is fixedly connected to the screw nut of the first screw transmission assembly.

[0019] Furthermore, the two first folding rods share a first folding drive mechanism; two opposite thread structures are provided at both ends of the screw of the first screw transmission assembly, screw nuts are provided on the two thread structures, and the two first folding rods are fixedly connected to the two screw nuts. In this way, the first folding drive motor can be used to synchronously drive the two first folding rods to move synchronously towards each other, which greatly simplifies the structure of components and reduces manufacturing costs.

[0020] Furthermore, the first folding transmission assembly also includes a synchronous wheel structure, the synchronous wheel structure includes a synchronous wheel and a synchronous belt, the synchronous wheel includes a driving wheel and a driven wheel, the driving wheel is coaxially arranged on the output shaft of the first folding drive motor, and the driven wheel is coaxially arranged on the screw rod.

[0021] Preferably, the second folding drive mechanism comprises a second folding drive motor and a second folding transmission assembly, the second folding drive motor is fixed on the frame, and the second folding rod is fixed on the belt of the second folding transmission assembly.

[0022] In a preferred embodiment of the present invention, a pressing member is provided on one side of the second gathering rod close to the bundling station, and the pressing member is used to further press the garbage bag at the bundling station to reduce the thickness of the garbage bag in the bundling direction;

[0023] The clamping member is provided with at least two clamping parts extending in the direction of the bundling station, and the clamping parts are arranged in the vertical direction; wherein, a bundling avoidance opening is formed between adjacent clamping parts, and the bundling nail passes through the bundling avoidance opening to receive the garbage bag inside. Through the above structure, when the second folding rod gathers the garbage bag to the bundling station, the clamping part of the clamping member enters the bundling station and squeezes the garbage bag in the bundling station. wherein, under the compression of the clamping part, the thickness of the garbage bag in the bundling direction can be reduced, so that the garbage bag here is completely located within the opening range of the bundling nail, ensuring that the bundling nail can receive the garbage bag inside when moving in the direction of the fixed pressure member, so as to be fully prepared for the bundling work, thereby obtaining a stable sealing quality.

[0024] Preferably, there are three pressing parts and two bundling avoidance openings, wherein the bundling nails for bundling the upper opening of the garbage bag being loaded with garbage pass through the upper bundling avoidance opening, and the bundling nails for bundling the lower opening of the next garbage bag pass through the lower bundling avoidance opening.

[0025] A preferred embodiment of the present invention is that two guide plates are provided at the opening of the bundling station, and a guide space gradually expanding outward from the bundling station is formed between the two guide plates. When the garbage bag approaches the bundling station, the two guide plates guide the garbage bag into the bundling station.

[0026] Preferably, a notch is provided on the guide plate for preventing the second gathering rod from approaching the bundling station.

[0027] A preferred embodiment of the present invention, wherein the bundling feeding mechanism includes a feeding frame, a supporting seat for supporting and placing bundling nails, and a feeding driving mechanism for driving the supporting seat to move upward, and a plurality of bundling nails are arranged vertically on the supporting seat and are lifted sequentially from top to bottom to the position to be bundled.

[0028] Preferably, the feeding drive mechanism includes a counterweight, a fixed pulley and a pull rope, wherein the fixed pulley is connected to the feeding frame in a transverse rotation, one end of the pull rope is connected to the counterweight, and the other end is connected to the support seat after passing the fixed pulley. Through the above structure, under the reverse transmission of the fixed pulley, the pull rope converts the gravity of the counterweight into the power to drive the support seat to move upward. When the top binding nail is tied to the garbage bag, the counterweight will drop a distance of the thickness of the binding nail, driving the support seat to move upward by the same distance, so that the binding nail at the top at this time rises to the position to be tied, ready for tying.

[0029] Furthermore, the supporting seats of the two groups of bundling and feeding mechanisms are fixedly connected, and the upper supporting surfaces of the two supporting seats are respectively located at two different heights; the two groups of bundling and feeding mechanisms share a feeding drive mechanism, and the other end of the pull rope is fixed between the two supporting seats. This can greatly simplify the structure of the bundling and feeding mechanism, making the structure more compact and occupying less space.

[0030] Furthermore, a vertical guide portion is provided on the loading frame, and a vertical guide groove is provided on the counterweight block to provide guidance when the counterweight block moves vertically.

[0031] In a preferred embodiment of the present invention, the bundling forming mechanism comprises a forming frame, an extrusion forming assembly and a forming driving mechanism, wherein a bundling channel extending laterally is provided in the forming frame; the extrusion forming assembly comprises a dynamic pressure piece and a fixed pressure piece, wherein in the driving direction of the forming driving mechanism, the fixed pressure piece and the dynamic pressure piece are respectively located at the front and rear of the bundling nail; the dynamic pressure piece and the bundling nail to be bundled are both arranged in the bundling channel, and the forming driving mechanism drives the dynamic pressure piece to squeeze the bundling nail onto the fixed pressure piece along the bundling channel;

[0032] The dynamic pressure piece is fixed on the driving end of the forming drive mechanism, and the fixed pressure piece is fixed on the forming frame; the fixed pressure piece is provided with a molding cavity on the side facing the bundling nail, and the bottom of the molding cavity is provided with an extrusion part; there are two extrusion parts, which respectively squeeze the two bundling feet of the bundling nail, and the extrusion surfaces of the two extrusion parts respectively extend obliquely toward each other's side walls at the two opposite side walls of the molding cavity, wherein the oblique direction includes the direction toward the inside of the molding cavity. Through the above structure, when the garbage bag is gathered to the bundling station, the forming drive mechanism drives the dynamic pressure piece to approach the bundling nail, and then drives the bundling nail to move toward the fixed pressure piece. In this process, since the opening of the bundling nail faces the garbage bag, and the garbage bag is located in the bundling station, as the forming drive mechanism continues to drive, after the bundling nail moves to the bundling station, the garbage bag is stuck in the bundling nail, and then continues to move toward the fixed pressure piece along with the bundling nail. When the bundling nail enters the molding cavity, the two bundling feet of the bundling nail respectively press against the extrusion surfaces of the two extrusion parts. Since the extrusion surfaces of the two extrusion parts are inclined toward the inside of the molding cavity to form inclined extrusion surfaces, the two bundling feet of the bundling nail are gradually pressed toward the opening along the corresponding extrusion surfaces under the drive of the molding drive mechanism to surround the garbage bag. The two bundling feet are directly wrapped around the garbage bag, thereby completing the bundling work, and the molding drive mechanism drives the dynamic pressure piece to reset.

[0033] Preferably, the inclined direction also includes a vertical direction, wherein the extrusion surface of one extrusion part is inclined upward, and the extrusion surface of the other extrusion part is inclined downward. The advantage of such a setting is that the two binding legs of the binding nail can be wrapped on the garbage bag in an up-down offset manner to prevent interference between the two, and at the same time, the binding circle can be as small as possible to improve the sealing effect of the garbage bag.

[0034] Preferably, a vertically extending feeding channel is further provided in the forming frame, and the top of the feeding channel is connected to the bundling channel; the overlapping portion of the bundling channel and the feeding channel constitutes a position to be bundled, and the bundling nails located at the top are placed at the position to be bundled.

[0035] Preferably, the forming drive mechanism is composed of a first folding drive mechanism for driving the first folding rod to move, and the dynamic pressure member and the first folding rod are simultaneously arranged on the driving end of the first folding drive mechanism; the two first folding rods are located at two different heights. Through the above structure, the first folding rod is first driven (at the same time, the dynamic pressure member also moves along and approaches the bundling nail, but no substantial bundling work has been performed) to perform preliminary folding work, and when the garbage bag is folded to the bundling station by the second folding rod, the dynamic pressure member is driven to perform bundling work. In this way, the same set of driving structures can be used to realize two different processes, which is conducive to simplifying the structure of components and reducing manufacturing costs.

[0036] Furthermore, the binding nails of the two groups of binding mechanisms are relatively arranged vertically on both sides of the binding station, and the forming drive mechanism drives the binding nails in opposite directions to bind the garbage bags.

[0037] Furthermore, the two bundling forming mechanisms share a forming drive mechanism, and two opposite thread structures are provided at both ends of the screw rod. In this way, one forming drive motor can be used to synchronously drive the two dynamic pressure members to move toward each other, and two stages of bundling work can be completed at the same time, which greatly simplifies the component structure and reduces the manufacturing cost.

[0038] In a preferred embodiment of the present invention, the separation mechanism comprises a heating wire for melting and cutting the garbage bag and a separation drive mechanism for driving the heating wire to approach the garbage bag.

[0039] Preferably, the separation drive mechanism is composed of a first folding drive mechanism for driving a first folding rod to move, and the heating wire is arranged on the first folding rod below; in terms of vertical height, the heating wire is located between two dynamic pressure members.

[0040] A smart trash can comprises a trash can body, a trash can cover and a packing device, wherein the packing device is arranged on the trash can cover.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The fully automatic garbage bag packaging device of the present invention can automatically complete the collection, bundling, sealing and separation of garbage bags, realizes fully automatic intelligent operation, and has good convenience of use.

[0043] 2. The fully automatic garbage bag packing device of the present invention adopts a bundling sealing method. By setting two sets of bundling mechanisms, the bundling nails are set at two different heights, so that the bundling nails located at the top seal the lower opening of the next garbage bag, ready to store garbage, and the bundling nails located at the bottom seal the upper opening of the garbage bag that is being loaded with garbage. Compared with the traditional melting sealing method, the sealing method of the present invention is more stable and will not be affected by the final shape of the garbage bag. The sealing quality is better, the sealing is high, and it is not easy to leak.

[0044] 3. Compared with the melt-sealed garbage bag, the opening of the garbage bag of the present invention is strongly tied by tying nails (metal nails), so the bag opening is more firm and can bear greater weight. BRIEF DESCRIPTION OF THE DRAWINGS

In this process, since the opening of the bundling nail 7 is facing the garbage bag, and the garbage bag is located in the bundling station 6, as the forming drive mechanism continues to drive, after the bundling nail 7 moves to the bundling station 6, the garbage bag is stuck in the bundling nail 7, and then continues to move in the direction of the fixed pressure piece 22 along with the bundling nail 7. When the tying nail 7 enters the molding cavity 22-1, the two tying feet of the tying nail 7 are respectively pressed against the extrusion surfaces of the two extrusion parts 22-2. Since the extrusion surfaces of the two extrusion parts 22-2 are inclined toward the inside of the molding cavity 22-1, an inclined extrusion surface is formed. Therefore, under the drive of the forming drive mechanism, the two tying feet of the tying nail 7 gradually press along the corresponding extrusion surface toward the opening direction to surround the garbage bag, and directly the two tying feet are completely wrapped around the garbage bag, thereby completing the tying work, and the forming drive mechanism drives the dynamic pressure piece 21 to reset. In addition, the tying forming mechanism in this embodiment can also adopt the structure of the aluminum nail machine in the prior art for pressurizing and wrapping the tying nail 7.

[0080] Furthermore, the tilting direction also includes a vertical direction, wherein the pressing surface of one pressing part 22-2 is tilted upward, and the pressing surface of the other pressing part 22-2 is tilted downward. The advantage of such a setting is that the two binding feet of the binding nail 7 can be wrapped on the garbage bag in an up-down offset manner to prevent interference between the two, and at the same time, the binding circle can be as small as possible to improve the sealing effect of the garbage bag.

[0081] See also Figure 16-17A vertically extending feeding channel 20-2 is also provided in the forming frame 20, and the top of the feeding channel 20-2 is connected to the bundling channel 20-1; the overlapping portion of the bundling channel 20-1 and the feeding channel 20-2 constitutes a position to be bundled, and the bundling nail 7 located at the top is placed at the position to be bundled.

[0082] See also Figure 7-9 In this embodiment, the forming drive mechanism is composed of the first folding drive mechanism, and the dynamic pressure piece 21 and the first folding rod 4 are simultaneously arranged on the driving end of the first folding drive mechanism, that is, arranged on the same screw nut; the two first folding rods are located at two different heights to avoid interference when the two move toward each other. Through the above structure, the first folding rod 4 is first driven (at the same time, the dynamic pressure piece 21 also moves along and approaches the bundling nail 7, but no substantial bundling work has been performed) to perform preliminary folding work, and when the garbage bag is folded to the bundling station 6 by the second folding rod 5, the dynamic pressure piece 21 is driven to perform bundling work. In this way, the same set of driving structure can be used to realize two different processes, which is conducive to simplifying the structure of components and reducing manufacturing costs.

[0083] See also Figure 7-9 The two groups of strapping mechanisms have their strapping nails 7 arranged vertically on both sides of the strapping station 6, and the forming drive mechanism drives the strapping nails 7 in opposite directions to strap the garbage bags. The two strapping forming mechanisms share a forming drive mechanism, and the two dynamic pressure members 21 are respectively connected to the two screw nuts 10 on the same screw 9. In this way, one driving motor can be used to synchronously drive the two dynamic pressure members to move in opposite directions, and two stages of strapping work can be completed at the same time, which greatly simplifies the component structure and reduces the manufacturing cost.

[0084] See also Figure 7-9 The separation mechanism includes a heating wire 23 for melting and cutting the garbage bag and a separation driving mechanism for driving the heating wire 23 to approach the garbage bag. In addition, the separation mechanism can also adopt other structures that can achieve cutting and separation, such as a shearing structure.

[0085] Furthermore, the separation drive mechanism is composed of a first folding drive mechanism for driving the first folding rod 4 to move, and the heating wire 23 is arranged on the first folding rod 4 located below; in terms of vertical height, the heating wire 23 is located between the two dynamic pressure members 21.

[0086] In this embodiment, there are two sets of electric drive mechanisms in total, one set is used to drive the two first folding rods 4, the two dynamic pressure parts 21 and the heating wire 23 to move laterally, which greatly optimizes the internal structure of the trash can and reduces the manufacturing cost; the other set is used to drive the second folding rod 5 to move laterally.

[0087] See also Figure 1-17 The working principle of the fully automatic garbage bag packaging device in this embodiment is:

[0088] When the garbage in the garbage bag reaches a certain amount, the packaging work begins. The folding drive mechanism first drives the first folding rod 4 to initially fold the unfolded garbage bag, and then drives the second folding rod 5 to fold the initially folded garbage bag again into the bundling station 6, and then carries out the bundling work.

[0089] Prior to this, the two groups of bundling feeding mechanisms respectively transport the two bundling nails 7 to the predetermined positions (the openings of the two bundling nails 7 are both facing the garbage bag), wherein the two bundling nails 7 are located at two different heights. Then, the two groups of bundling forming mechanisms respectively bundle the corresponding bundling nails 7 on the garbage bag, and the two bundling nails 7 located at different heights firmly pack and press the garbage bag, and respectively seal the upper opening of the garbage bag currently loaded with garbage and the lower opening of the next garbage bag. At this time, the straight-through garbage bag forms a three-section structure, and then the separation mechanism of the garbage bin divides the garbage bag at the position between the two bundling nails 7, so that one garbage bag is separated into two, the lower one is a completely sealed used garbage bag, and the upper one is a standby garbage bag ready for storing garbage, thereby completing the packaging work, and when the user takes the used garbage bag out of the garbage bin, garbage collection can be started again.

[0090] Example 2

[0091] See also Figure 18-19 , which is different from the first embodiment, the two extrusion parts 22-2 in the present embodiment are symmetrically arranged in the fixed cavity 22-1 of the fixed pressure member 22, and extend toward each other into the inside of the fixed cavity 22-1 to form two inclined extrusion surfaces. When the binding nail 7 is tied to the garbage bag, the binding nail 7 becomes a ring structure.

[0092] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
