DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 —The embodiment shown in 5.

[0029] A waste storage bag packaging structure comprises a mounting frame 1, wherein the mounting frame 1 is used for mounting and fixing; a heat sealing assembly 2, wherein two heat sealing assemblies 2 are slidably mounted on the mounting frame 1, and the two heat sealing assemblies 2 move toward each other to cut off the heat seal of the storage bag between the two; a driving assembly 3, wherein the driving assembly 3 drives the two heat sealing assemblies 2 to move toward or away from the storage bag; and a tearing-off bag-feeding assembly 4, wherein the two tearing-off bag-feeding assemblies 4 move synchronously with the heat sealing assemblies 2 on the same side, and the two tearing-off bag-feeding assemblies 4 move toward each other to pull downward the heat-sealed storage bag between the two, so as to separate the heat-sealed storage bag from the unheat-sealed storage bag.

[0030] See also Figures 1 to 4As shown, during the heat sealing process, the heat sealing components 2 on both sides are first driven by the driving components 3 on both sides to move toward the storage bag, and the heat sealing and cutting of the bag mouth are completed when the two heat sealing components 2 are in contact with the storage bag. Incomplete cutting may occur during the heat sealing and cutting. In order to ensure that the heat-sealed storage bag and the unheat-sealed storage bag are separated from each other, after the heat sealing and cutting are completed, the heat-sealed storage bag below is pulled down by tearing off the bag feeding component 4, so that the incompletely cut heat-sealed storage bag is separated from the unheat-sealed storage bag, ensuring that the heat-sealed storage bag and the unheat-sealed storage bag can be completely separated after each heat sealing and cutting.

[0031] Moreover, after the heat-sealed storage bag is torn apart, the unheat-sealed bag is pulled downward by tearing the bag feeding component 4, so that the unheat-sealed bag's to-be-heat-sealed area enters between the heat-sealing components 2 and waits for the next heat-sealing, thereby realizing automatic bag feeding of the unheat-sealed bag.

[0032] It should be noted here that the cutting mentioned above can be performed by melting at the heat sealing area or by cutting with a cutter. The cutting method can be selected according to needs, and the heat sealing and cutting operations of the bag opening can be completed in the heat sealing process.

[0033] See also Figure 5 As shown, the cutting position is in the heat-sealing area, so that the lower bag opening of the unheat-sealed storage bag can be ensured to be in a closed state, ensuring that garbage cannot fall from the lower bag opening when stored, that is, each heat sealing will close the upper bag opening of the lower storage bag and the lower bag opening of the upper storage bag.

[0034] The mounting frame 1 includes guide groove plates 11 arranged on the left and right sides, and two pairs of slide plates 12 sliding on the guide groove plates 11 on the left and right sides. The heat sealing assembly 2 is installed between the two slide plates 12 located on the same side of the storage bag; a connecting rod 13 is fixedly installed between the two slide plates 12 located on the same side of the storage bag.

[0035] See also Figure 1 and Figure 2 As shown, the slide plates 12 on the left and right sides can move relative to each other under the guidance of the guide groove plate 11, thereby driving the heat sealing component 2 and the tear-off bag-introducing component 4 to approach each other, so that the heat sealing component 2 heat-seals the storage bag and tears the heat-sealed storage bag below the tear-off bag-introducing component 4 apart.

[0036] The two driving assemblies (3) have the same structure. The driving assembly 3 includes two first driven gears 32 that mesh with each other. A driven rod 33 is hingedly installed on the outer circumference of each of the first driven gears 32. A transmission rod 34 that transmits power to the heat sealing assembly 2 is installed at the other end of each of the driven rods 33. It also includes a heat sealing drive motor 35 that drives the two first driven gears 32 to rotate. The first driven gear 32 rotates to drive the transmission rod 34 to fold inward or extend outward.

[0037] The driving assembly 3 further includes a first driving gear 31 installed at the power output end of the heat sealing driving motor 35 , and the first driving gear 31 is meshed with one of the two first driven gears 32 for transmission.

[0038] See also Figure 1 and Figure 2 As shown, in the present embodiment, the transmission rod 34 is transmission-connected with the heat sealing assembly 2. It can be understood that the transmission rod 34 can transmit power to the heat sealing assembly 2 and drive the heat sealing assembly 2 to move. The transmission connection can be in the form of a hinged connection, thereby driving the heat sealing assembly 2 to move, and the two ends of the heat sealing assembly 2 are connected to the slide plate 12, so that during the movement of the slide plate 12, the slide plate 12 can also be driven to slide under the guidance of the guide groove plate 11.

[0039] Specifically, the first driving gear 31 is driven to rotate by the heat sealing driving motor 35. Since the first driving gear 31 is meshed with one of the two first driven gears 32 and the two first driven gears 32 are meshed with each other, the two first driven gears 32 can also be driven to rotate while the first driving gear 31 rotates. As the first driven gear 32 rotates, the driven rod 33 and the transmission rod 34 move toward the storage bag, thereby driving the heat sealing components 2 on the left and right sides to move toward each other, and heat sealing and cutting the storage bag between the two.

[0040] The tear-off bag-introducing assembly 4 includes two first tear-off bag-introducing structures 4a and two second tear-off bag-introducing structures 4b. The two first tear-off bag-introducing structures 4a are located below the two driving assemblies 3, and the two second tear-off bag-introducing structures 4b are located above the two driving assemblies 3. A first tear-off bag-introducing structure 4a and a second tear-off bag-introducing structure 4b are respectively arranged above and below each of the driving assemblies 3. The first tear-off bag-introducing structure 4a and the second tear-off bag-introducing structure 4b have the same structure.

[0041] The first tearing bag feeding structure 4a tearing bag feeding component includes a rotating shaft 41 that moves synchronously with the heat sealing component 2, and a plurality of eccentric wheels 42 are axially installed on the outer surface of the rotating shaft 41. The eccentric wheels 42 rotate around the rotating shaft 41 to make eccentric movements toward or away from the storage bag.

[0042] The power input end of the rotating shaft 41 is equipped with a second driven gear 43, and also includes a tearing motor 45. The power output end of the tearing motor 45 is equipped with a second driving gear 44 that meshes with the second driven gear 43 and also includes a mounting block 46 installed on the connecting rod 13, and the tearing motor 45 is fixedly mounted on the mounting block 46.

[0043] See also Figure 1 and Figure 2 As shown, the rotating shaft 41 is installed between the two slides 12 located on one side of the storage bag, and the rotating shaft 41 can rotate. Since the mounting block 46 is fixedly connected to the connecting rod 13, when the slide 12 and the connecting rod 13 move under the drive of the driving assembly 3, the tear-off bag feeding assembly 4 will also move accordingly, so that the pulling blocks 47 located on both sides of the storage bag can move toward the storage bag. In this embodiment, the connecting rod 13 is located in the avoidance groove 48.

[0044] Specifically, in the tearing process, first, the two first tearing bag feeding structures 4a below are brought close to each other to pull down and tear off the heat-sealed storage bag between them, so as to separate the heat-sealed storage bag from the unheat-sealed storage bag. When the heat-sealed storage bag needs to be torn apart, first, the tearing motors 45 of the two first tearing bag feeding structures 4a below transmit power to the rotating shaft 41 through the meshing of the second driven gear 43 and the second driving gear 44, and drive the rotating shaft 41 to rotate. When the rotating shaft 41 rotates, it will drive the The multiple eccentric wheels 42 on its outer surface also rotate and make eccentric motion. Similarly, the pulling block 47 located on the outer surface of the eccentric wheel 42 will make eccentric motion. Therefore, during the rotation process, the two pulling blocks 47 close to the ends of the storage bag will come into contact to pull down the storage bag. Since the pulling blocks 47 will move in the lateral direction during the rotation, in order to prevent the pulling blocks 47 from interfering with the connecting rod 13, an avoidance groove 48 is designed to avoid the interference. In addition, the connecting rod 13 also supports the ends of the pulling blocks 47 to a certain extent.

[0045] After the heat-sealed storage bag is torn apart in the above-mentioned process, the two driving components 3 drive the two heat-sealing components 2 to move away from each other, and the storage bag is in a heat-sealed state with contact heat sealing. Next, the two first tear-off bag-feeding structures 4a at the bottom and the two second tear-off bag-feeding structures 4b at the top work together at the same time. The two first tear-off bag-feeding structures 4a approach each other and the two second tear-off bag-feeding structures 4b approach each other to pull the unheat-sealed storage bag downward, so that the storage bag is pulled between the two heat-sealing components 2, thereby realizing the bag feeding of the storage bag. The specific pulling process is the same as the above-mentioned tearing process and will not be elaborated here.

[0046] The heat sealing assembly 2 includes a heating element and a heat sealing plate. The heating element transfers heat to the heat sealing plate to heat-seal the storage bag.

[0047] The utility model also discloses a toilet, comprising the above-mentioned waste storage bag packaging structure, the toilet comprises a toilet body, the waste storage packaging structure can be installed on the side of the toilet body, so that after the toilet is used, the waste gas can be thrown into the storage bag of the above-mentioned packaging structure, which is convenient to use, or the waste storage packaging structure is arranged under a trash can, and the trash can is placed on one side of the toilet.

[0048] The utility model also discloses a trash can, comprising the above-mentioned waste storage bag packaging structure, the trash can is connected from top to bottom, a barrel-shaped storage bag is sleeved on the outer surface of the trash can, and the waste storage bag packaging structure is located at the lower opening of the trash can.

[0049] The working process of the utility model is as follows: first, the heat sealing driving motor 35 drives the two first driven gears 32 to rotate through the transmission of the first driving gear 31. When the first driven gear 32 rotates, the driven rod 33 and the transmission rod 34 will move in the opposite direction to the storage bag, thereby driving the two heat sealing components 2 to move closer to each other to cut off the heat seal of the storage bag. When the two components move closer to each other, the slides 12 on both sides will also be driven closer to each other. The two first tearing bag feeding structures 4a at the bottom tear the heat-sealed storage bag apart to separate it from the unheat-sealed storage bag. For this reason, after the heat sealing is completed, the tearing motor 45 in the two first tearing bag feeding structures 4a at the bottom moves through the second driven gear 43 and the second main gear 44. The meshing transmission of the moving gear 44 drives the rotating shaft 41 to rotate, causing the eccentric wheel 42 and the pulling block 47 to make an eccentric movement. During the eccentric movement, the two pulling blocks 47 approach each other and pull downward the heat-sealed storage bag located between them, thereby separating the heat-sealed storage bag below from the unheat-sealed storage bag above, completing the heat-sealing cutting and tearing operations. After the tearing is completed, the two driving components 3 drive the two heat-sealing components 2 to move away from each other in a contact heat-sealing state, and then the two first tearing bag-feeding structures 4a and the two second tearing bag-feeding structures 4b pull the unheat-sealed storage bag downward, so that the heat-sealed area of ​​the unheat-sealed storage bag is located between the two heat-sealing components 2, thereby achieving bag feeding and waiting for the next heat sealing.
