[0027] Example 1: Reference Figure 1-4A sofa internal sponge forming device comprises a workbench 1, one side of the workbench 1 is fixedly connected with four supporting legs 101, one side of the workbench 1 is fixedly connected with a cutting mechanism 2, one side of the workbench 1 is fixedly connected with a fixing frame 3, the interior of the fixing frame 3 is fixedly connected with a forming component 4, the cutting mechanism 2 comprises a transverse cutting component 201 and a longitudinal cutting component 202, the transverse cutting component 201 comprises two fixing plates 2011, one side of the two fixing plates 2011 is fixedly connected with one side of the workbench 1, one side of the two fixing plates 2011 is fixedly connected with two limiting shells 2012, the moving block 2017 is restricted by the limiting shell 2012 to prevent the first threaded rod 2013 from driving the moving block 2017 to rotate when it rotates, so that the moving block 2017 will not rotate with the first threaded rod 2013 when it rotates, and then the moving block 2017 will move along the first threaded rod 2013.

[0028] The two fixing plates 2011 are internally rotatably connected to two first threaded rods 2013 , and the exteriors of the two first threaded rods 2013 are both rotatably connected to the interior of the limiting shell 2012 .

[0029] The outside of the two first threaded rods 2013 is fixedly connected to a pulley 2014, and the outsides of the two pulleys 2014 are rotationally connected via a belt. The two pulleys 2014 rotate synchronously via the belt, so that the two first threaded rods 2013 rotate synchronously.

[0030] One side of one of the fixed plates 2011 is fixedly connected to a connecting plate 2015, one side of the connecting plate 2015 is fixedly connected to a first motor 2016, the output end of the first motor 2016 is fixedly connected to one side of one of the first threaded rods 2013, and the output end of the first motor 2016 drives one of the first threaded rods 2013 to rotate, so that the first threaded rod 2013 drives one of the pulleys 2014 to rotate, and then the two first threaded rods 2013 are rotated synchronously through the two pulleys 2014.

[0031] The outer surfaces of the two first threaded rods 2013 are threadedly connected to a moving block 2017, and the exteriors of the two moving blocks 2017 are slidably connected to the interior of the limiting shell 2012. When the two first threaded rods 2013 rotate inside the fixed plate 2011 and the limiting shell 2012, the two moving blocks 2017 move synchronously along the first threaded rods 2013 inside the limiting shell 2012, thereby driving the two first cutting knives 2019 to move to cut the formed sofa sponge.

[0032] One side of each moving block 2017 is fixedly connected to a cylinder 2018, and one side of each cylinder 2018 is fixedly connected to a first cutting knife 2019. The first cutting knife 2019 is pushed up and down by the output end of the cylinder 2018. When the transverse cutting component 201 is used, the first cutting knife 2019 is pushed down by the output end of the cylinder 2018, so that the moving block 2017 drives the cylinder 2018 and the first cutting knife 2019 to move and perform transverse cutting on the sofa sponge. After the cutting is completed, the output end of the cylinder 2018 drives the first cutting knife 2019 to rise.

[0033] The longitudinal cutting assembly 202 includes two fixed shells 2021 . The exteriors of the two fixed shells 2021 are fixedly connected to the interior of the fixed frame 3 . The two fixed shells 2021 are symmetrically distributed.

[0034] A second motor 2022 is fixedly connected to the inside of the two fixed shells 2021, and a second threaded rod 2023 is fixedly connected to the output ends of the two second motors 2022. A telescopic rod 2024 is threadedly connected to the outer surfaces of the two second threaded rods 2023. The second threaded rod 2023 is driven to rotate inside the fixed shell 2021 by the output end of the second motor 2022, so that the telescopic rod 2024 moves inside the fixed shell 2021 along the second threaded rod 2023.

[0035] The outside of the two telescopic rods 2024 is fixedly connected to a limit ring 2025, and the outsides of the two telescopic rods 2024 and the two limit rings 2025 are slidably connected to the inside of the fixed shell 2021. A clamping block is provided inside the fixed shell 2021, and a groove is provided on one side of the limit ring 2025. The clamping block cooperates with the groove so that when the second threaded rod 2023 rotates, the telescopic rod 2024 will not rotate with it, thereby realizing the movement of the telescopic rod 2024. One side of the two telescopic rods 2024 is fixedly connected to a second cutting knife 2026, and the second cutting knife 2026 is driven to move by the movement of the telescopic rod 2024 to cut the formed sofa sponge longitudinally.

[0036] The molding assembly 4 includes two hydraulic cylinders 401, the exteriors of the two hydraulic cylinders 401 are fixedly connected to the interior of the fixed frame 3, and the output ends of the two hydraulic cylinders 401 are fixedly connected to a molding plate 402, and the molding plate 402 is pushed up and down by the output ends of the two hydraulic cylinders 401. When the sofa sponge is molded, the molding plate 402 is pushed down by the output ends of the hydraulic cylinders 401 to compress and mold the sofa sponge. After the compression molding of the sofa sponge is completed, the output ends of the hydraulic cylinders 401 drive the molding plate 402 to rise.

[0037] The first motor 2016, the second motor 2022, etc. that appear in the utility model are all connected to the external main controller and the 220V AC power through a transformer, and the main controller can be a conventional known device that controls a computer, etc. The electrical components provided by the utility model are only used for the technical solution according to the structural characteristics of the product.

Therefore, the technical personnel in this field can clearly obtain the corresponding use effect through the technical solution provided by the utility model.

[0038] Embodiment 2: A cleaning component can be provided on the basis of embodiment 1, through which the waste cut from the molding sponge can be cleaned and collected, which is beneficial to improving the cleanliness of the molding device and reducing the labor intensity of the operators.

[0039] In the utility model, the operator places the sofa sponge to be processed on the workbench 1, and the molding assembly 4 pushes the molding plate 402 to rise and fall through the output ends of the two hydraulic cylinders 401. When the sofa sponge is molded, the molding plate 402 is pushed down by the output end of the hydraulic cylinder 401 to compress and mold the sofa sponge. After the compression molding of the sofa sponge is completed, the transverse cutting assembly 201 of the cutting mechanism 2 drives one of the first threaded rods 2013 to rotate through the output end of the first motor 2016, so that the first threaded rod 2013 drives one of the first threaded rods 2013 to rotate. The pulley 2014 rotates, and then the two first threaded rods 2013 are rotated synchronously through the two pulleys 2014. The two pulleys 2014 rotate synchronously through the belt, so that the two first threaded rods 2013 rotate synchronously. When the two first threaded rods 2013 rotate inside the fixed plate 2011 and the limiting shell 2012, the two moving blocks 2017 move synchronously along the first threaded rods 2013 inside the limiting shell 2012, and the first cutting knife 2019 is pushed up through the output end of the cylinder 2018. When the transverse cutting assembly 201 is used, the output end of the cylinder 2018 pushes the first cutting knife 2019 to descend, so that the moving block 2017 drives the cylinder 2018 and the first cutting knife 2019 to move and cut the sofa sponge transversely. After the cutting is completed, the output end of the cylinder 2018 drives the first cutting knife 2019 to rise, and then the longitudinal cutting assembly 202 drives the second threaded rod 2023 to rotate inside the fixed shell 2021 through the output end of the second motor 2022, so that the telescopic rod 2024 moves along the second threaded rod 2023. The interior of the fixed shell 2021 moves, and the telescopic rod 2024 moves to drive the second cutting knife 2026 to move to cut the molded sofa sponge longitudinally. After the molding device compresses and molds the sofa sponge, the molded sofa sponge can be cut by the cutting mechanism 2, which eliminates the need for operators to cut the molded sofa sponge later. This solves the problem that the molding device still requires operators to cut the size of the sofa sponge after molding it, which is beneficial to improving the working efficiency of the molding device and reducing the labor intensity of the operators.
