It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0055] As described in the background technology, the cat litter scoop in the existing cat litter box separates the condensed excrement from the cat litter and scoops the excrement to the packing mechanism, but most of the existing packing mechanisms are complicated to operate or have low reliability. To this end, the present application provides a new type of packing mechanism, which can solve the problems of complicated operation and low reliability of the packing mechanism in the prior art. The packing mechanism of the present application will be described in detail below with reference to the accompanying drawings.

[0056] It should be noted that the “first direction” of this application is the Figure 5 The direction indicated by the letter X.

[0057] See also Figures 1 to 9 As shown, the present application provides a packaging mechanism, which is at least used to package packaging bags 50. The packaging mechanism includes a base (not shown in the drawings), a first clamping and hot-pressing assembly 10 and a second clamping and hot-pressing assembly 20.

[0058] Specifically, the first clamping and hot pressing assembly 10 is arranged on the first side of the base, and the first clamping and hot pressing assembly 10 includes a heating part 11 and a first clamping part 12, and the first clamping parts 12 are arranged on two opposite sides of the heating part 11; the second clamping and hot pressing assembly 20 is arranged on the second side of the base opposite to the first side, and the second clamping and hot pressing assembly 20 includes a top part 21 and a second clamping part 22, and the second clamping parts 22 are arranged on two opposite sides of the top part 21.

[0059] Among them, at least one of the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 is movably arranged on the base, and the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 have a first position state in which they abut against each other and a second position state in which they are separated from each other. When the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 are in the first position state, the first clamping part 12 and the second clamping part 22 have a clamping position 60 for at least packaging the packaging bag 50, the heating part 11 and the abutting top part 21 have a hot pressing position 70 for at least hot pressing the packaging bag 50, and the clamping position 60 and the hot pressing position 70 are staggered.

[0060] It can be understood that in the present application, "at least one of the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 is movably disposed on the base" includes the following three situations: (1) the first clamping and hot-pressing assembly 10 is movably disposed on the first side of the base, and the second clamping and hot-pressing assembly 20 is fixed on the second side of the base; (2) the first clamping and hot-pressing assembly 10 is fixed on the first side of the base, and the second clamping and hot-pressing assembly 20 is movably disposed on the second side of the base; (3) the first clamping and hot-pressing assembly 10 is movably disposed on the first side of the base, and the second clamping and hot-pressing assembly 20 is movably disposed on the second side of the base.

[0061] It can be understood that the present application clamps the packing bag 50 by the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 to achieve clamping, sealing and cutting of the packing bag 50. The entire packing process does not require manual processing, is simple to operate, effectively avoids human hands from contacting the packaged objects, is clean and hygienic, and improves the packing efficiency to a certain extent. Among them, the first clamping part 12 and the second clamping part 22 cooperate with each other to achieve the clamping of the packing bag 50, and the heating part 11 and the top part 21 cooperate with each other to achieve the packaging and cutting of the packing bag 50.

[0062] Specifically, in the present application, when the packaging mechanism is actually processed, the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 are both arranged on the base, and the first clamping and hot-pressing assembly 10 is located on the first side of the base, and the second clamping and hot-pressing assembly 20 is located on the second side of the base, and the packaging mechanism also includes a bag box, and the bag box contains a packaging bag 50. Before the packaging mechanism starts packaging, the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 are in a second position state separated from each other and are respectively located on opposite sides of the packaging bag 50. When the cat litter ball enters the packaging bag 50, the first clamping and hot-pressing assembly 10 and / or the second clamping and hot-pressing assembly 20 are controlled to move (i.e., the first clamping and hot-pressing assembly 10 is controlled to move from the first side of the base toward the second side and / or the second clamping and hot-pressing assembly 20 is controlled to move from the second side of the base toward the first side) to clamp and package the packaging bag 50 containing the cat litter ball part.

[0063] When the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 move to the first position state, the first clamping portion 12 and the second clamping portion 22 abut against each other, and the heating portion 11 and the abutting top portion 21 abut against each other, so that the packing bag 50 filled with cat litter and drooping naturally can be clamped. At this time, the packing bag 50 is sealed and melted by the cooperation between the heating portion 11 and the abutting top portion 21. In this process, since the clamping position 60 and the hot pressing position 70 are staggered, the clamped portion of the packing bag 50 can be pulled in a staggered manner, so that the clamped portion of the packing bag 50 is deformed due to the staggered pulling, and then the packing bag 50 can be cut more easily during the melting process, which effectively ensures the normal operation of the subsequent packing work of the packing mechanism and improves the reliability of the packing mechanism. It should be noted that "the clamping position 60 and the hot pressing position 70 are staggered" means that the first plane where the clamping position 60 is located and the second plane where the hot pressing position 70 is located do not overlap. Figure 2 as well as Figure 4 The clamping position 60 and the heat pressing position 70 are shown in two misaligned states.

[0064] That is to say, compared with the packaging mechanism in the prior art, the present application can perform offset pulling on the clamped portion of the packaging bag 50 by staggering the clamping position 60 of the first clamping portion 12 and the second clamping portion 22 with the hot pressing position 70 of the heating portion 11 and the abutting top portion 21, thereby deforming the clamped portion of the packaging bag 50, effectively ensuring that the packaging bag 50 can be more easily cut off when the heating portion 11 is melted, thereby ensuring that the next packaging of the packaging mechanism can proceed normally, and the entire packaging process is simple to operate and effectively improves the reliability of the packaging mechanism.

[0065] Further, see Figure 6 to Figure 7 As shown, the first clamping hot pressing assembly 10 in this embodiment also includes a first installation body 13, the first installation body 13 is arranged on the base, and the heating part 11 and the first clamping part 12 are both arranged on the first installation body 13. Such an arrangement has a simple structure and is convenient for processing and assembling the heating part 11 and the first clamping part 12. Specifically, the heating part 11 and the first clamping part 12 are both arranged on the side of the first installation body 13 close to the second clamping hot pressing assembly 20, so that they can move from the first side of the base to the second side under the drive of the first installation body 13, and then can cooperate with the second clamping hot pressing assembly 20 to achieve clamping, packaging and cutting of the packaging bag 50.

[0066] Further, see Figures 8 to 9As shown, the second clamping and hot pressing assembly 20 in this embodiment also includes a second installation body 23, which is arranged on the base, and the abutting top portion 21 and the second clamping portion 22 are both arranged on the second installation body 23. Such an arrangement has a simple structure and is convenient for processing and assembling the abutting top portion 21 and the second clamping portion 22. Specifically, the abutting top portion 21 and the second clamping portion 22 are both arranged on the side of the second installation body 23 close to the first clamping and hot pressing assembly 10, so that they can move from the second side of the base toward the first side under the drive of the second installation body 23, and then can cooperate with the first clamping and hot pressing assembly 10 to achieve the clamping, packaging and cutting of the packaging bag 50.

[0067] Specifically, at least one of the first installation body 13 and the second installation body 23 in this embodiment is movably disposed on the base. That is to say, in this embodiment, the first installation body 13 can be movably disposed on the base, while the second installation body 23 is fixed on the base; the first installation body 13 can also be fixed on the base, while the second installation body 23 can be movably disposed on the base; the first installation body 13 can also be movably disposed on the base, while the second installation body 23 can be movably disposed on the base, and this application does not make specific limitations here.

[0068] Further, see Figure 7 As shown, the first clamping portion 12 of the present embodiment is provided with at least one first extension section 14, and the first extension section 14 extends along the first direction; a first elastic member 15 is sleeved on the first extension section 14, one end of the first elastic member 15 abuts against the first extension section 14, and the other end of the first elastic member 15 abuts against the first installation body 13. In this way, the clamping position 60 of the first clamping portion 12 and the second clamping portion 22 can be staggered with the hot pressing position 70 of the heating portion 11 and the abutting top portion 21, so that the packing bag 50 is staggered and pulled to increase the deformation of the packing bag 50, and then the packing bag 50 can be more easily cut off when the heating portion 11 melts, thereby ensuring that the next packing of the packing mechanism can be carried out normally.

[0069] It is understandable that in this embodiment, at least one first extension section 14 is provided on the first clamping portion 12, that is, the first extension section 14 may include one, two, three or more than three, which is not specifically limited in this application and can be designed according to actual processing requirements. Figure 7The figure shows the situation when there are two first extension sections 14, and the two first extension sections 14 are arranged at intervals. Such arrangement can prevent the first clamping part 12 from being skewed when it abuts against the second clamping part 22, thereby preventing the skewed first clamping part 12 from contacting other positions of the first clamping hot pressing assembly 10 and being worn, and to a certain extent prolonging the service life of the first clamping hot pressing assembly 10, effectively ensuring the normal operation of the packaging mechanism, and improving the reliability of the packaging mechanism.

[0070] Specifically, in the embodiment shown in the present application, at least one first extension section 14 is provided on the first clamping part 12, while the first extension section 14 is not provided on the second clamping part 22. In this way, when the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 are in the first position state, the first clamping part 12 and the second clamping part 22 are in contact with each other. At this time, since the first elastic member 15 is elastic and can be extended and retracted when subjected to external force, the first clamping part 12 will compress the first elastic member 15 under the abutment of the second clamping part 22, so that the first clamping part 12 moves toward the direction close to the first installation body 13, thereby driving the clamping position 60 of the first clamping part 12 and the second clamping part 22 to shift toward the direction of the first installation body 13, so as to realize the staggered setting of the clamping position 60 and the hot pressing position 70, thereby increasing the deformation of the clamped part of the packing bag 50, effectively ensuring that the packing bag 50 is easier to be cut, and the operation is simple, and the reliability of the packing mechanism is effectively improved.

[0071] Of course, in another embodiment of the present application that is not shown, the first clamping part 12 is not provided with the first extension section 14, and the second clamping part 22 is provided with at least one first extension section 14. In this way, when the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 are in the first position state, the first clamping part 12 and the second clamping part 22 are in contact with each other. At this time, since the first elastic member 15 is elastic and can be extended and retracted when subjected to external force, the second clamping part 22 will compress the first elastic member 15 under the abutment of the first clamping part 12, so that the second clamping part 22 is offset in the direction close to the second installation body 23, so as to realize the staggered setting of the clamping position 60 and the hot pressing position 70, increase the deformation of the clamped part of the packaging bag 50, effectively ensure that the packaging bag 50 is easier to be cut, simple to operate, and effectively improve the reliability of the packaging mechanism.

[0072] Specifically, the first elastic member 15 in this embodiment can be a spring, or an elastic gasket, an elastic sleeve, etc., and any other deformation methods based on the concept of this application are within the protection scope of this application. Figure 7 The case where the first elastic member 15 is a spring is shown.

[0073] Further, see Fig. 9 As shown, in the embodiment shown in the present application, the abutting top portion 21 is provided with at least one second extension section 24, and the second extension section 24 extends along the first direction; the second mounting body 23 is provided with an abutting portion 25, and the abutting portion 25 is provided with a limited position section 251; a second elastic member 26 is sleeved on the limited position section 251, and one end of the second elastic member 26 abuts against the second extension section 24, and the other end of the second elastic member 26 abuts against the abutting portion 25. In this way, the hot pressing position 70 of the heating portion 11 and the abutting top portion 21 can be staggered with the clamping position 60 of the first clamping portion 12 and the second clamping portion 22, so as to pull the packing bag 50 in a staggered manner to increase the deformation of the packing bag 50, and then the packing bag 50 can be more easily cut off when the heating portion 11 is melted, thereby ensuring that the next packing of the packing mechanism can be carried out normally, and effectively improving the reliability of the packing mechanism. It is understandable that in this embodiment, at least one second extension section 24 is provided on the abutment portion 21, that is, the second extension section 24 may include one, two, three or more than three, which is not specifically limited in this application and can be designed according to actual processing requirements. Fig. 9 The figure shows the situation when there are two second extension sections 24, and the two second extension sections 24 are arranged at intervals. Such arrangement can prevent the abutting top portion 21 from being skewed when abutting against the heating portion 11, thereby preventing the abutting top portion 21 from being in contact with other positions of the second clamping and hot pressing assembly 20 and being worn, thereby extending the service life of the second clamping and hot pressing assembly 20 to a certain extent, and effectively ensuring the normal operation of the packaging mechanism.

[0074] Specifically, in the present embodiment, when the first clamping hot pressing assembly 10 and the second clamping hot pressing assembly 20 are in the first position state, the first clamping portion 12 and the second clamping portion 22 are abutted together. At this time, since the second elastic member 26 is elastic and can be retracted and contracted when subjected to external force, the abutting top portion 21 will compress the second elastic member 26 under the abutment of the heating portion 11, thereby causing the abutting top portion 21 to move toward the direction close to the second installation body 23, thereby driving the hot pressing position 70 of the heating portion 11 and the abutting top portion 21 to shift toward the direction of the second installation body 23, so as to realize the staggered setting of the clamping position 60 and the hot pressing position 70, thereby increasing the deformation of the clamped part of the packaging bag 50, effectively ensuring that the packaging bag 50 is easier to be cut, and improving the reliability of the packaging structure.

[0075] Of course, in another embodiment not shown in the present application, the second extension section 24 is not provided on the abutting top portion 21, and at least one second extension section 24 is provided on the heating portion 11. In this way, when the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 are in the first position state, the first clamping portion 12 and the second clamping portion 22 are abutted together. At this time, since the second elastic member 26 is elastic and can be extended and retracted when subjected to external force, the heating portion 11 will compress the second elastic member 26 under the abutment of the abutting top portion 21, so that the heating portion 11 is offset in the direction close to the first installation body 13, so as to realize the staggered setting of the clamping position 60 and the hot pressing position 70, increase the deformation of the clamped part of the packaging bag 50, effectively ensure that the packaging bag 50 is easier to be cut, and improve the reliability of the packaging structure.

[0076] Specifically, the second elastic member 26 in this embodiment can be a spring, or an elastic gasket, an elastic sleeve, etc., and any other deformation methods based on the concept of this application are within the protection scope of this application. Fig. 9 The case where the second elastic member 26 is a spring is shown.

[0077] It can be understood that, in one embodiment of the present application, when the first clamping and hot-pressing assembly 10 is movably disposed on the first side of the base, and the second clamping and hot-pressing assembly 20 is fixed on the second side of the base, the first clamping and hot-pressing assembly 10 can be driven by the first driving assembly 30 to move from the first side of the base toward the second side of the base, while the second clamping and hot-pressing assembly 20 does not move, so as to clamp and pack the packing bag 50 containing the cat litter ball portion; in another embodiment of the present application, when the first clamping and hot-pressing assembly 10 is fixed on the first side of the base, and the second clamping and hot-pressing assembly 20 is movably disposed on the second side of the base, the second clamping and hot-pressing assembly 20 can be driven by the second driving assembly 40 to move from the second side of the base toward the first side of the base The first clamping and hot-pressing assembly 10 moves sideways, while the first clamping and hot-pressing assembly 10 does not move, so as to clamp and pack the packing bag 50 containing the cat litter ball portion; in another embodiment of the present application, when the first clamping and hot-pressing assembly 10 is movably arranged on the first side of the base, and the second clamping and hot-pressing assembly 20 is movably arranged on the second side of the base, the first driving assembly 30 can be used to drive the first clamping and hot-pressing assembly 10 to move from the first side of the base toward the second side of the base, and at the same time, the second clamping and hot-pressing assembly 20 can be driven by the second driving assembly 40 to move from the second side of the base toward the first side of the base (that is, the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 move toward each other), so as to clamp and pack the packing bag 50 containing the cat litter ball portion.

[0078] Further, as shown in the figure, the first installation body 13 in this embodiment has a first installation cavity 130, and a first driving assembly 30 is arranged in the first installation cavity 130. The first driving assembly 30 is connected to the first clamping and hot pressing assembly 10 to drive the first clamping and hot pressing assembly 10 to move between the first position state and the second position state. That is to say, this embodiment can drive the first clamping and hot pressing assembly 10 to move from the first side of the base toward the second side and abut against the second clamping and hot pressing assembly 20 by utilizing the driving action of the first driving assembly 30. The structure is simple and easy to control, which reduces the difficulty of operating the packaging mechanism and effectively ensures the stability of the packaging mechanism. At the same time, the first driving assembly 30 can accurately control the displacement of the first clamping and hot pressing assembly 10, so that the first clamping and hot pressing assembly 10 can achieve efficient and accurate clamping and hot pressing operations.

[0079] Further, see Figure 7 As shown, the first driving assembly 30 in this embodiment includes a first driving motor, a first gear set 32 ​​and a first rack. Among them, the first driving motor is arranged in the first installation cavity 130; the first gear set 32 ​​is arranged on the first installation body 13; the first rack (not shown in the drawings) is arranged on the base, and the first rack is meshed with the first gear set 32; the first driving motor is connected to the first gear set 32 ​​to drive the first gear set 32 ​​to drive the first clamping and hot pressing assembly 10 to reciprocate along the first rack between the first position state and the second position state. With such a configuration, the first clamping and hot pressing assembly 10 can be accurately displaced, so that the first clamping and hot pressing assembly 10 can achieve efficient and accurate clamping and hot pressing operations.

[0080] Specifically, the first drive motor is a power source responsible for providing driving force, and installing the first drive motor in the first installation cavity 130 can protect the first drive motor and prevent the first drive motor from being affected by external structures. At the same time, the overall volume of the first clamping and hot pressing assembly 10 is reduced, and the weight of the packaging mechanism is reduced; the first gear set 32 ​​is connected to the first drive motor and can convert the driving force of the first drive motor into the required form of motion, thereby driving the first clamping and hot pressing assembly 10 to reciprocate between the first position state and the second position state; the first rack plays a guiding role. This embodiment utilizes the first rack to mesh with the first gear set 32, which can achieve precise positioning and repetitive movement of the first gear set 32.

[0081] Furthermore, the first gear set 32 ​​in this embodiment includes a plurality of gears, a portion of which is disposed in the first mounting cavity 130, another portion of which is disposed on the outer periphery of the first mounting body 13 and located on opposite sides of the first mounting body 13 along the first direction, and each gear is in transmission connection with each other. In other words, the gears in this embodiment may include two, three, four or more than four, which is not specifically limited in this application. Figure 7 The figure shows the situation when the first gear set 32 ​​includes four gears, wherein the first gear 321 and the second gear 322 are located in the first installation cavity 130, the first gear 321 is connected to the first driving motor, and the first gear 321 rotates under the drive of the first driving motor, thereby driving the second gear 322 to rotate; the third gear 323 and the fourth gear 324 are located on the outer periphery of the first installation body 13 and are located at opposite ends of the first installation body 13 along the first direction, the third gear 323, the second gear 322 and the fourth gear 324 are sequentially arranged on the first transmission shaft, and the first transmission shaft drives the third gear 323 and the fourth gear 324 to rotate under the rotation of the second gear 322, and the third gear 323 and the fourth gear 324 are meshed with the first rack.

[0082] Further, see Fig. 9 As shown, the second mounting body 23 in this embodiment has a second mounting cavity 230, and a second driving assembly 40 is arranged in the second mounting cavity 230. The second driving assembly 40 is drivingly connected to the second clamping and hot pressing assembly 20 to drive the second clamping and hot pressing assembly 20 to move between the first position state and the second position state. That is to say, this embodiment can drive the second clamping and hot pressing assembly 20 to move from the second side of the base toward the first side and abut against the first clamping and hot pressing assembly 10 by utilizing the driving action of the second driving assembly 40. The structure is simple and easy to control, which reduces the difficulty of operating the packaging mechanism and effectively ensures the stability of the packaging mechanism. At the same time, the second driving assembly 40 can accurately control the displacement of the second clamping and hot pressing assembly 20, so that the second clamping and hot pressing assembly 20 can achieve efficient and accurate clamping and hot pressing operations.

[0083] Further, see Fig. 9As shown, the second drive assembly 40 in this embodiment includes a second drive motor 41, a second gear set 42 and a second rack. Specifically, the second drive motor 41 is arranged in the second mounting cavity 230; the second gear set 42 is arranged on the second mounting body 23; the second rack is arranged on the base (not shown in the drawings), and the second rack is meshed with the second gear set 42; wherein the second drive motor 41 is drivingly connected to the second gear set 42 to drive the second gear set 42 to drive the second clamping and hot pressing assembly 20 to reciprocate along the second rack between the first position state and the second position state. With such a configuration, the second clamping and hot pressing assembly 20 can be accurately displaced, so that the second clamping and hot pressing assembly 20 can achieve efficient and accurate clamping and hot pressing operations.

[0084] Specifically, the second drive motor 41 is a power source responsible for providing driving force, and installing the second drive motor 41 in the second installation cavity 230 can protect the second drive motor 41 and prevent the second drive motor 41 from being affected by the external structure. At the same time, the overall volume of the second clamping and hot pressing assembly 20 is reduced, and the weight of the packaging mechanism is reduced; the second gear set 42 is driven and connected to the second drive motor 41, and can convert the driving force of the second drive motor 41 into the required form of motion, thereby driving the second clamping and hot pressing assembly 20 to reciprocate between the first position state and the second position state; the second rack plays a guiding role. This embodiment utilizes the second rack to mesh with the second gear set 42, which can achieve precise positioning and repetitive movement of the second gear set 42.

[0085] Furthermore, the second gear set 42 in this embodiment includes a plurality of gears, a portion of which is disposed in the second mounting cavity 230, another portion of which is disposed on the outer periphery of the second mounting body 23 and located on opposite sides of the second mounting body 23 along the first direction, and each gear is in transmission connection with each other. In other words, the gears in this embodiment may include two, three, four or more than four, which is not specifically limited in this application. Fig. 9 The figure shows the situation when the second gear set 42 includes four gears, wherein the fifth gear 421 and the sixth gear 422 are located in the first installation cavity 130, the fifth gear 421 is drivingly connected to the second drive motor 41, and the fifth gear 421 rotates under the drive of the second drive motor 41, thereby driving the sixth gear 422 to rotate; the seventh gear 423 and the eighth gear 424 are located on the outer periphery of the second installation body 23 and at opposite ends of the second installation body 23 along the first direction, the seventh gear 423, the sixth gear 422 and the eighth gear 424 are sequentially arranged on the second transmission shaft, and the second transmission shaft drives the seventh gear 423 and the eighth gear 424 to rotate under the rotation of the sixth gear 422, and the seventh gear 423 and the eighth gear 424 are meshed with the second rack.

[0086] Further, in order to ensure stable clamping between the first clamping portion 12 and the second clamping portion 22, see Figure 2 , Figure 4 , Figure 7 as well as Fig. 9 As shown, in this embodiment, a clamping groove 221 is provided on one of the side of the first clamping portion 12 close to the second clamping portion 22 and the side of the second clamping portion 22 close to the first clamping portion 12, and a butting protrusion 121 adapted to the clamping groove 221 is provided on the other. Wherein, the first clamping portion 12 is a first clamping block, and the second clamping portion 22 is a second clamping block, and a clamping groove 221 is provided on one of the side of the first clamping block close to the second clamping block and the side of the second clamping block close to the first clamping block, and a butting protrusion 121 adapted to the clamping groove 221 is provided on the other. It can be understood that when the clamping groove 221 is provided on the first clamping block, the butting protrusion 121 is provided on the second clamping block; when the first clamping block is provided with the butting protrusion 121, the clamping groove 221 is provided on the second clamping block. In this embodiment, the attachment Figure 7 as well as Fig. 9 The figure shows a situation where the first clamping block is provided with a butting protrusion 121 and the second clamping block is provided with a clamping groove 221. In this way, the first clamping block and the second clamping block can be tightly combined, so that the packing bag 50 can be tightly clamped by the first clamping block and the second clamping block, thereby improving the packing efficiency of the packing bag 50. Moreover, through the stable clamping of the first clamping block and the second clamping block, the damage of the packing bag 50 caused by uneven friction can be reduced, thereby extending the service life of the packing bag 50.

[0087] Furthermore, the clamping groove 221 in this embodiment is a V-shaped groove or a U-shaped groove. Such a configuration has a simple structure, is easy to process, and reduces the manufacturing cost.

[0088] Optionally, in this embodiment, the first clamping portion 12 and the second clamping portion 22 include elastic structures such as foam or foamed silicone, which is not specifically limited in the present application. As long as it is other deformation methods based on the concept of the present application, they are within the protection scope of the present application.

[0089] Further, see Figure 7As shown, the heating part 11 in this embodiment includes a heating wire holder 111, and the heating wire holder 111 includes a base 1111 and a heating wire 1112. The base 1111 is arranged on the first installation body 13, and the heating wire 1112 is embedded in the base 1111 and protrudes from the outer surface of the base 1111 away from the first installation body 13. In this embodiment, the heating wire holder 111 can be used to pack, seal and fuse the packing bag 50, so that the packing bag 50 containing the cat litter balls falls. Such a setting has a simple structure, does not require additional sealing components, and simultaneously achieves sealing and fusing, and does not require additional blades for cutting, which effectively improves the sealing effect of the packing bag 50.

[0090] Furthermore, the first clamping hot pressing assembly 10 and the second clamping hot pressing assembly 20 in this embodiment both include anti-sticking cloths, which are respectively coated on the heating portion 11 and the abutting top portion 21. Such a configuration can prevent the molten adhesive generated by the hot melting of the heating portion 11 from adhering to the heating portion 11 and the abutting top portion 21, and effectively ensure that the heating portion 11 and the abutting top portion 21 can perform normal hot pressing sealing and fusing on the packaging bag 50.

[0091] Furthermore, the anti-sticking cloth in this embodiment includes Teflon high temperature cloth. Specifically, Teflon high temperature cloth has the advantages of good temperature resistance and good anti-sticking, and the Teflon high temperature cloth is respectively coated on the heating part 11 and the top part 21, which effectively prevents the molten glue generated by the heat melting of the packaging bag 50 in the heating part 11 from adhering to the heating part 11 and the top part 21.

[0092] Further, see Figure 6 to Figure 7 As shown, the first clamping hot pressing assembly 10 in this embodiment further includes a first gathering portion 90, which is disposed on the first installation body 13. The first gathering portion 90 has two first gathering arms 91 extending in the same direction, and the two first gathering arms 91 are arranged at intervals to form a first opening groove 92, and the notch of the first opening groove 92 is gradually expanded. Specifically, the arrangement of the first gathering portion 90 can gather the side wall of the packing bag 50 from the circumference of the packing bag 50, which is conducive to the first clamping portion 12 and the second clamping portion 22 to clamp the packing bag 50, and at the same time, it is conducive to the heating portion 11 and the top portion 21 to encapsulate the packing bag 50.

[0093] Further, see Figures 8 to 9As shown, the second clamping hot pressing assembly 20 in this embodiment further includes a second gathering portion 100, which is disposed on the second mounting body 23. The second gathering portion 100 has two second gathering arms 101 extending in the same direction, and the two second gathering arms 101 are arranged at intervals to form a second opening groove 102, and the notch of the second opening groove 102 is gradually expanded. Specifically, the second gathering portion 100 can gather the side wall of the packing bag 50 from the circumference of the packing bag 50, which is conducive to the first clamping portion 12 and the second clamping portion 22 to clamp the packing bag 50, and at the same time, it is conducive to the heating portion 11 and the top portion 21 to package the packing bag 50.

[0094] Specifically, the working principle of the packaging mechanism of this application is as follows:

[0095] First, the packing bag 50 is installed so that the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 are located on opposite sides of the packing bag 50;

[0096] Secondly, the first driving assembly 30 drives the first installation body 13 to move from the first side of the base toward the second side, and the second driving assembly 40 drives the second installation body 23 to move from the second side of the base toward the first side, so that the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 are in contact with each other to compress, seal and fuse the packaging bag 50, wherein the first clamping portion 12 and the heating portion 11 move following the first installation body 13, and the second clamping portion 22 and the abutting portion 21 move following the second installation body 23;

[0097] Since the first clamping portion 12 is provided with a first elastic member 15 and the abutting portion 21 is provided with a second elastic member 26, when the first clamping and hot-pressing assembly 10 and the second clamping and hot-pressing assembly 20 meet and clamp the naturally hanging packing bag 50 filled with cat litter, the first clamping portion 12 abuts against the second clamping portion 22, thereby compressing the first elastic member 15, and then the first clamping portion 12 and the second clamping portion 22 both move toward the direction close to the first installation body 13, and at the same time, the heating portion 11 abuts against the abutting portion 21, thereby compressing the second elastic member 26. , thereby causing the heating portion 11 and the abutting top portion 21 to move toward the direction close to the second mounting body 23. During this process, the clamping positions 60 of the first clamping portion 12 and the second clamping portion 22, and the hot pressing positions 70 of the heating portion 11 and the abutting top portion 21 are staggered, which can perform staggered pulling on the clamped portion of the packing bag 50, causing the clamped portion of the packing bag 50 to be deformed due to the staggered pulling, thereby making the packing bag 50 easier to be cut off during the melting process, thereby effectively ensuring the normal operation of the subsequent packing work of the packing mechanism.

[0098] On the other hand, see Fig.10As shown, the embodiment of the present application further provides a cat litter box, which includes the above-mentioned packing mechanism, and therefore, the cat litter box includes all the technical effects of the above-mentioned packing mechanism. Since the technical effects of the packing mechanism have been described in detail above, they will not be repeated here.

[0099] Specifically, see Fig.10 As shown, the packaging mechanism in this embodiment is overall configured as a drawer type, has an inward buckled handle, and is installed on the cat litter box to receive and package the cat litter balls.

[0100] On the other hand, the embodiment of the present application also provides a control method of a packaging mechanism, which is executed by the above-mentioned packaging mechanism, and therefore, the control method of the packaging mechanism includes all the technical effects of the above-mentioned packaging mechanism. Since the technical effects of the packaging mechanism have been described in detail above, they will not be repeated here.

[0101] Specifically, the control method of the packaging mechanism in this embodiment includes:

[0102] Step S1: Control the first clamping and hot pressing assembly 10 and / or the second clamping and hot pressing assembly 20 to move to a first position state, so that the clamping position 60 and the hot pressing position 70 are staggered.

[0103] Specifically, during the operation of the packaging mechanism, the first clamping and hot pressing assembly 10 and / or the second clamping and hot pressing assembly 20 can be controlled to move to the first position state by the first driving assembly 30 and / or the second driving assembly 40, so that the clamping position 60 and the hot pressing position 70 are staggered. That is to say, the first clamping and hot pressing assembly 10 can be driven by the first driving assembly 30 to move toward the second clamping and hot pressing assembly 20, while the second clamping and hot pressing assembly 20 remains stationary; the second clamping and hot pressing assembly 20 can also be driven by the second driving assembly 40 to move toward the first clamping and hot pressing assembly 10, while the first clamping and hot pressing assembly 10 remains stationary; the first clamping and hot pressing assembly 10 can also be driven by the first driving assembly 30 to move toward the second clamping and hot pressing assembly 20, and the second clamping and hot pressing assembly 20 can be driven by the second driving assembly 40 to move toward the first clamping and hot pressing assembly 10 (i.e., the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 move toward each other).

[0104] Step S2: After the clamping position 60 and the hot pressing position 70 are staggered, and before controlling the heating part 11 to heat the packaging bag 50, the control method of the packaging mechanism also includes: controlling the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 to reciprocate along the first direction to stretch the packaging bag 50 to a predetermined length.

[0105] Specifically, in the actual control process, the first driving assembly 30 and the second driving assembly 40 can be used to control the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 to reciprocate along the first direction (i.e., after the first clamping and hot pressing assembly 10 and the second clamping and hot pressing assembly 20 clamp the packing bag 50, they reciprocate along the first direction to pull the new packing bag 50 out of the bag box). It should be noted that the "predetermined length" in this embodiment is not specifically limited here and can be designed according to actual needs.

[0106] Step S3: Control the heating unit 11 to heat the packing bag 50 to perform heat-melt sealing on the packing bag 50. Thereafter, the heating unit 11 stops heating for a first predetermined time T1, and then controls the first clamping hot-pressing assembly 10 and / or the second clamping hot-pressing assembly 20 to move to a second position state.

[0107] Specifically, during the actual operation, the heating unit 11 is turned on to perform heat-melt sealing on the packing bag 50. After the heating is completed, the heating unit 11 stops running for the first predetermined time T1. At this time, sufficient cooling time can be provided for the heating unit 11 to prevent the seal of the packing bag 50 from being torn apart during the process of the first clamping and hot-pressing assembly 10 and / or the second clamping and hot-pressing assembly 20 moving to the second position state. Then, the first driving assembly 30 and / or the second driving assembly 40 controls the first clamping and hot-pressing assembly 10 and / or the second clamping and hot-pressing assembly 20 to move to the second position state, so that the packing bag 50 after heat-melt sealing is separated from the packing bag to be used.

[0108] Further, in this embodiment, the step of controlling the heating unit 11 to heat the packing bag 50 to perform heat-melt sealing on the packing bag 50 includes: controlling the heating unit 11 to operate at a predetermined temperature C1 for a second predetermined time T2 to perform heat-melt sealing on the packing bag 50 .

[0109] Specifically, when the heating unit 11 is heating the packing bag 50, it only needs to operate at the predetermined temperature C1 for the second predetermined time T2 to seal the packing bag 50 currently in use, and at the same time, it can seal the bottom of the packing bag 50 to be used next, so as to ensure the normal use of the packing bag 50 to be used.

[0110] Furthermore, the first predetermined time in this embodiment satisfies the relationship: 2s≤T1≤6s, for example, 2s, 3s, 4s, 5s, 6s and any value therebetween.

[0111] Further, the predetermined temperature C1 in this embodiment satisfies the relationship: 200°C≤C1≤250°C, for example, 200°C, 210°C, 220°C, 230°C, 240°C, 250°C and any value therebetween.

[0112] Furthermore, the second predetermined time T2 in this embodiment satisfies the relationship: 15s<T2<17s, for example, 15.2s, 15.4s, 15.6s, 15.8s, 16s, 16.2s, 16.4s, 16.6s, 16.8s and any value between 15s and 17s.

[0113] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0114] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0115] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
