Description

Technical Field

[0001] The invention belongs to the technical field of intelligent trash cans, and in particular relates to a trash can structure for automatically packing trash bags. Background Art

[0002] At present, intelligent home products are constantly improving people's quality of life, and smart trash cans are one of them. Trash cans are a household product that people often use in their daily lives. As people pursue higher and higher quality home environments, they have gradually evolved from the initial simple trash cans to modern smart trash cans.

[0003] For example, the Chinese invention patent document with authorization publication number CN109319332B discloses an automatically sealed trash can, including a trash can body, a trash bag storage device is provided above the trash can body, a trash bag feeding device and a trash bag sealing device are provided below the trash bag storage device, the trash bag feeding device and the trash bag sealing device are controlled by a control circuit, the control circuit is connected to a power supply, the trash bag feeding device includes a first trash bag feeding roller and a second trash bag feeding roller which are arranged relatively and can move relative to each other, a trash bag feeding roller driving mechanism is connected to the first trash bag feeding roller or the second trash bag feeding roller, the trash bag sealing device includes a first slide and a second slide which are arranged relatively and can move relative to each other, a trash bag sealing member is provided on the first slide or the second slide, and the trash bag sealing member is located on the end surface where the first slide and the second slide are connected. Relative arrangement means that the first bag-feeding roller and the second bag-feeding roller are located on the left and right sides respectively. When the first bag-feeding roller and the second bag-feeding roller need to feed the garbage bag, the two bag-feeding rollers move from the two sides to the middle. After the two rollers come into contact, the friction between the rollers and the plastic film of the garbage bag tube drives the garbage bag tube to move into the main body of the garbage bin to achieve bag feeding. After the bag feeding is completed, the two bag-feeding rollers can move from the middle to the opposite directions on both sides and return to the initial position. The garbage bag sealing part includes an electric heating round wire, and an electric heating flat wire is provided on one side or both sides of the electric heating round wire. Multiple sealing and cutting can be achieved, making the sealing more reliable.

[0004] In the technical solution of the above patent document, the first slide and the second slide are brought close to each other to clamp the garbage bag film, and the flat wire on the second slide heat-seals the garbage bag film, and the round wire cuts the garbage bag; thus, a flat seal can be formed at the bottom and top of the garbage bag. However, the seal at the bottom of the garbage bag is formed by two layers of film being welded together to form a straight seal. Since the mechanical strength of the garbage bag film is not high, it is easy to cause cracks at the seal position.

[0005] In order to overcome the technical defects of the above-mentioned patent document, the Chinese invention patent document with authorization announcement number CN111977218B discloses a flexible packaging mechanism for garbage bags and a garbage can, including a mounting plate, a driving device, a closing mechanism, and a sealing device arranged on the mounting plate, wherein: the mounting plate is provided with a mounting plate through hole for the garbage bag and the garbage to pass through, a flexible belt limiting groove is arranged on the mounting plate around the mounting plate through hole, the driving device includes a motor and a reduction transmission gear driven by the motor, and the sealing device is fixedly arranged at a position on one side of the mounting plate through hole, and is used to perform a sealing operation on the closed garbage bag; the closing mechanism includes a flexible belt arranged around the mounting plate through hole, the head end of the flexible belt is fixedly arranged with the mounting plate, the middle part bypasses the sealing end face of the sealing device, and is meshed with the reduction transmission gear, and the end moves back and forth along the flexible belt limiting groove with the rotation of the reduction transmission gear, so that the rotation of the reduction transmission gear can drive the flexible belt to tighten or reset around the sealing device; the flexible belt has high temperature resistant insulation characteristics at least at the part in contact with the sealing end face, and the driving device and the sealing device are communicatively connected with the control device. A flexible belt is used for closing, and the flexible belt is meshed and connected with the reduction transmission gear device of the driving device. Under the driving action of the driving device and the guiding and limiting action of the flexible belt limiting groove, the garbage bag can be effectively gathered to the sealing end surface, and cooperate with the sealing device to realize the packaging and sealing operation. Compared with the existing flexible packaging mechanism for garbage bags with rigid pressure rod packaging and sealing, the flexible packaging mechanism for garbage bags of the present invention has fewer structural parts, which greatly reduces the processing and assembly accuracy requirements for each spare part, reduces the production and assembly costs, and has a simplified structure, a low failure rate, and better reliability. At the same time, when the amount of garbage in the garbage bag exceeds the closing plane, the flexible packaging mechanism for garbage bags of the present invention can still achieve good sealing and packaging, while ensuring the sealing and packaging quality.

[0006] It can be seen that in the technical solution of the above patent document, a flexible belt is used to gather the garbage bag film on the positioning block, and the garbage bag is heat-sealed and cut at the same time by the heating wire on the positioning block. The heat seal is completed after the heat seal is gathered, which can increase the strength of the seal, and a gathered heat seal is formed at the top and bottom of the garbage bag, thereby forming a hand-held position for picking up. However, in the patent document CN111977218B, when the garbage bag is pulled onto the positioning block by a flexible belt, there is a corner at the contact position of the flexible belt and the positioning block, and the corner position cannot make the flexible belt and the positioning block completely fit. When the garbage belt is pulled to the corner or the back of the positioning block, it will cause the problem that the position cannot be heat-sealed, which will lead to leakage.

[0035] In one embodiment of the garbage bin structure for automatically packing garbage bags of the present invention, please refer to Figures 1 to 8 , a trash can with automatic trash bag packaging can realize automatic transportation and heat-sealing packaging of trash bags, realize intelligence, and meet the needs of the market and users. Specifically, the trash can includes a barrel body 100, an upper shell 200 and a heat-sealing device 300. Among them, a accommodating chamber 101 is provided in the barrel body 100, and the upper shell 200 is arranged at the top of the barrel body 100, and covers the accommodating chamber 101. An installation chamber 210 and a heat-sealing chamber 220 are provided in the upper shell 200, and the installation chamber 210 is used to store the trash bag film roll to be heat-sealed. An input port 211 is provided on the top side of the installation chamber 210, so that the trash can be put into the trash bag in the trash can from the input port 211, and an air-avoiding port 212 is provided on the bottom side, so that the trash bag can be inserted into the accommodating chamber 101.

[0036] Please refer to Figure 4 and Figure 5The heat sealing device 300 is arranged in the heat sealing chamber 220, and is used to heat seal the bottom and mouth of the garbage bag film, and cut and pack the garbage bags. Specifically, the heat sealing device 300 includes a pad 310, a clamping plate 320, a roll 330, a driving mechanism 340 and an electric heating element. The pad 310 and the driving mechanism 340 are installed in the heat sealing chamber 220, and one end of the clamping plate 320 is pivotally connected to the pad 310, and between the clamping plate 320 and the pad 310. Specifically, a connection position is provided on the pad 310, and the clamping plate 320 is connected to the connection position through a pivot, so that the clamping plate 320 can rotate around the pivot. One end of the roll 330 is connected to the clamping plate 320, and the other end is connected to the driving mechanism 340, so that the roll 330 forms a zoom structure with the clamping plate 320 and the pad 310. The electric heating element is arranged on the inner side of the pad 310 or the clamping plate 320. Preferably, the electric heating element is arranged on the pad 310, so that it is more convenient to connect the electric heating element to electricity. Specifically, the electric heating element includes a heat-sealing heating element 350 and a heating wire 360. Preferably, the heat-sealing heating element 350 is divided into two groups, one of which is used for packaging and sealing the garbage bag, and the other group of heat-sealing heating elements 300 is used for heat sealing the bottom of the next garbage bag. Specifically, the two heat-sealing heating elements 350 and the heating wire 360 ​​are arranged on the inner side of the pad 310 or the splint 320, and the heating wire 360 ​​is located between the two heat-sealing heating elements 350. Among them, the heat-sealing heating element 350 adopts an electric heating block, or uses a heating wire wound on a carrier of a flat heat-insulating material, so as to ensure the heating surface and increase the area of ​​heat sealing.

[0037] In the garbage bin structure for automatic packaging of garbage bags of this embodiment, the garbage bag films that are orderly stored can be loaded into the installation cavity 210, and the free ends of the garbage bag films are heat-sealed and extended into the accommodating cavity 101. When the garbage bags are heat-sealed and packaged, the driving mechanism 340 drives the reel 330 to shrink. During the shrinking process, the reel 330 gathers the garbage bags and pushes them between the clamping plate 320 and the pad 310. When the driving mechanism 340 continues to drive the reel 330, the clamping plate 320 and the pad 310 clamp and press the garbage bags. The electric heating wire 360 ​​can cut the garbage bags, and the cut garbage bags are heated and fused under the action of the two heat-sealing heating elements 300 to achieve the sealing effect. At the same time, the bottom of the next garbage bag that needs to be filled with garbage is sealed to form a bottom seal of the garbage bag. The heat-sealed seal after being folded can form a hand-held position, which is convenient for picking up garbage bags, and by setting up two different elements for heat sealing and cutting, the length from the heat-sealing position to the incision position can be increased, thereby increasing the hand-held position, making it more convenient to take out the packaged garbage bags from the accommodating chamber 101. Since the drive mechanism 340 is used to drive the roll belt, the roll belt 330 pulls the clamping plate 320 and the pad 310 to clamp the garbage bag, it can ensure that sufficient heat-sealing pressure is applied to the garbage bag, so that the seal of the garbage bag can be completely heat-sealed to avoid leakage. In addition, cutting and heat sealing are implemented separately using two independent structures, so as to avoid the seal being located at the cutting position, which can further increase the stability after cutting and heat sealing.

[0038] Further, refer to Figures 1 to 3 A cover plate 201 is rotatably connected to the top side of the upper shell 200, and the input port 211 is closed by the cover plate 201. When garbage needs to be put in, the cover plate 201 can be opened.

[0039] For further information, please refer to Figure 3 The cover plates 201 are arranged in two groups and are symmetrically arranged, and are opened and closed electrically. Specifically, the cover plates 201 are provided with rotating shafts 202 in sequence, and are rotatably connected to the upper shell 200 through the rotating shafts 202. The ends of the rotating shafts 202 are provided with transmission gears 203. The upper shell 200 is provided with a transmission shaft 204, and the two ends of the transmission shaft 204 are provided with disc gears 205, and the disc gears 205 are meshed with the corresponding transmission gears 203. The transmission shaft 204 is connected to the driving motor 206. Therefore, the two cover plates 201 can be opened and closed by the driving motor 206.

[0040] Furthermore, the upper shell 200 can be pivotally connected to the barrel body 100, so that the barrel body 100 can be opened through the connection position between the upper shell 200 and the barrel body 100, and the garbage bag in which the garbage is packed can be taken out.

[0041] Furthermore, the electric heating element is arranged on the backing plate 310, and a soft pad 370 is arranged on the inner side of the clamping plate 320, which is used to support the electric heating element to clamp the garbage bag. Specifically, when the clamping plate 320 and the backing plate 310 clamp the garbage bag, the soft pad 370 plays a role of flexible support for the garbage bag, which is more convenient to cut and heat-seal the garbage bag. Furthermore, a support pad 380 is also arranged on the soft pad 370, and the support pad 380 cooperates with the electric heating wire 360, which further helps the electric heating wire 360 ​​to cut the garbage bag. In addition, the support pad can also be arranged on the backing plate 310, and the electric heating wire 360 ​​is arranged on the support pad, thereby increasing the height of the electric heating wire 360, which helps the electric heating wire 360 ​​to cut the garbage bag.

[0042] Further, refer to Figure 6 and Figure 7 , there are two rolls 330, and they are respectively arranged on both sides of the clamping plate 320. In this embodiment, two rolls 330 are used to apply tension to the clamping plate 320, thereby increasing the stability of the force applied to the clamping plate 320 and ensuring the stability of the heat sealing of the garbage bag. In addition, when the two rolls 330 are rolled together, the area where the garbage bag needs to be heat-sealed and cut is limited between the two rolls 330, and the area where the garbage bag needs to be heat-sealed and cut is limited by the two rolls 330, thereby avoiding the problem of deviation of the cutting and heat-sealing areas of the garbage bag.

[0043] Furthermore, refer to Figure 6 and Figure 7 The garbage bin structure for automatic packaging of garbage bags is also provided with a steering structure, one end of the roll 330 passes through the steering structure and is connected to the driving mechanism 340; the steering mechanism is used to limit the roll 330 to be located on one side of the heat-sealing area formed by the electric heating element. Thus, when the roll 330 collects the garbage bag, the collected garbage bag can be completely located in the heat-sealing area. Further, the steering structure is arranged on the guide hole 311 on the pad, and the steering hole 311 is located on one side of the heat-sealing area formed by the electric heating element. Specifically, one end of the roll 330 passes through the guide hole 311 and is connected to the driving mechanism 340. The steering position of the roll 330 is completely located on one side of the length direction of the heat-sealing heating element 350. In this embodiment, when the driving mechanism 340 pulls the roll 330, the roll 330 can completely collect the garbage bag on the heat-sealing heating element 350, avoid the phenomenon of leakage of the garbage bag, and provide the stability of the heat seal. More preferably, a guide is further provided in the guide hole 311, and the guide guide guides the roll 330 to avoid the wear of the roll 330. In addition, the steering mechanism is also provided as a steering shaft provided in the heat sealing chamber 220, or directly as a driving mechanism 340.

[0044] Further, refer to Figures 4 to 7The driving mechanism 340 includes a motor 341 and a traction wheel 342 . The motor 341 is disposed in the heat sealing chamber 220 . The traction wheel 342 is connected to the motor 341 . The winding belt 330 is connected to the traction wheel 342 .

[0045] Further, a specific embodiment of the traction wheel 342, specifically, the traction wheel 342 is connected to the gear of the motor 341, and a limiter 343 is also provided on one side of the gear, and a limit gap is formed between the limiter 343 and the gear, and the belt 330 is a toothed belt passing through the limit gap, and the belt 330 is meshed with the gear. More specifically, a bracket 390 is also provided on one side of the pad 310, and the bracket 390 is provided with a reduction box, and the reduction box is provided with two output shafts, and the output shafts are provided with gears, and the motor 341 is connected to the input end of the reduction box. The two gears are connected to the belt 330. In this embodiment, the motor 341 drives the two gears to rotate synchronously through the reduction box, and drives the belt 330 to pull the clamping plate 320 and the pad 310.

[0046] Furthermore, another embodiment of the traction wheel 342 is, specifically, the traction wheel 342 can be a ratchet wheel, and the belt 330 is provided with equidistant holes that cooperate with the ratchet wheel. The teeth of the ratchet wheel cooperate with the equidistant holes, thereby achieving pulling of the belt 330.

[0047] The traction wheel 342 may also be composed of two rollers. Since the two rollers clamp and convey the web 330 , the conveyance of the web 330 is achieved.

[0048] Further, refer to Figure 4 and Figure 5 A track groove 221 is also provided in the heat sealing cavity 220 , and the free end of the roll tape 330 passes through the limiting gap and then extends into the track groove 221 .

[0049] Further, refer to Figure 2 A negative pressure device 110 is provided in the receiving chamber 101 of the barrel 100, which is used to form a negative pressure in the receiving chamber 101, so as to absorb the garbage bag and transport it downward and fit it to the inner wall of the receiving chamber 101. Specifically, after the packed garbage bag is taken out, the negative pressure device 110 can be used to absorb the film of the garbage bag downward so that the garbage bag fits to the inner wall of the receiving chamber 101, so as to facilitate garbage collection.

[0050] Further, refer to Figure 2 The accommodating chamber 101 is also provided with an identification device 120. The garbage bag is provided with a label. The identification device 120 is used to identify the label and distinguish the height position of the garbage bag in the accommodating chamber. The identification device is connected to the controller of the garbage bin. After the identification device identifies the label, the controller can control the heat sealing device to avoid the garbage bag not being heat-sealed at the heat-sealing position, thereby ensuring the normal heat sealing.
