[0036] like Figure 1 As shown, the double-layer conveyor line 1 is used to transport the turnover tooling, which is used to place paper sheets, foam, and base plates, etc. The front-end elevator 2 and the rear-end elevator 9 are used to realize the interchange of the turnover tooling between the upper and lower layers of the double-layer conveyor line 1, realizing the cyclical transport of the turnover tooling. Multiple blocking mechanisms and positioning mechanisms are also installed on the double-layer conveyor line 1 for positioning the turnover tooling. In this embodiment, the double-layer conveyor line 1, turnover tooling, front-end elevator 2, gluing mechanism 5, rear-end elevator 9, blocking mechanisms, and positioning mechanisms all adopt existing technologies, and their structures will not be described in detail in this embodiment.

[0037] like Figures 1-4 As shown, the paper feeding and forming mechanism 3 is used to form paper sheets and transport the formed paper sheets to the corresponding turnover tooling on the double-layer conveyor line 1. In this embodiment, the paper feeding and forming mechanism 3 adopts the prior art, and its specific structure will not be described in detail here. However, in order to improve the paper sheet forming effect, it is necessary to fold the corners of the paper sheet before forming. For this reason, the aforementioned corner folding device is installed on the paper feeding and forming mechanism 3.

[0038] like Figure 1 and Figure 5 As shown, the foam feeding mechanism 4 includes a first frame 15, a storage frame 16, a foam hopper 17, a pushing component, a receiving component, and a picking component.

The receiving plate 21 is connected to the output end of the receiving cylinder 20. Symmetrically distributed receiving guide plates 22 are installed on the inner sides of both sides of the storage frame 16. When the foam is pushed, the receiving cylinder 20 drives the receiving plate 21 to move closer to each other. The foam pushed by the pushing block 19 is restricted between the receiving plate 21 and the receiving guide plate 22.

[0041] The material handling assembly includes a lifting actuator 23, a material handling adjustment plate 24, and a material handling head 25. The lifting actuator 23 is mounted on the double-layer conveyor line 1 via a column. The material handling adjustment plate 24 is mounted on the output end of the lifting actuator 23. The lifting actuator 23 drives the material handling adjustment plate 24 to move up and down. The material handling head 25 is mounted on the material handling adjustment plate 24. The position of the material handling head 25 can be adjusted on the material handling adjustment plate 24 according to the different specifications of the base tray. After the foam is pushed to the receiving assembly, the material handling head 25 descends and absorbs the foam. The receiving cylinder 20 drives the receiving tray 21 to retract. The positioning mechanism lifts the turnover fixture. The material handling head 25 installs the absorbed foam in the turnover fixture. In this embodiment, the lifting actuator 23 adopts, but is not limited to, a cylinder + guide rail structure. Other structures that can drive the material handling adjustment plate 24 to achieve lifting are also applicable.

[0042] like Figure 1 , Figure 6 and Figure 7 As shown, the bottom plate feeding mechanism 6 includes a second frame 37, a bottom plate hopper assembly 38, a pulling assembly 39, a feeding assembly 40, and a bottom plate adsorption assembly 41.

In this embodiment, the bottom plate hopper assembly 38, the pulling assembly 39, and the bottom plate adsorption assembly 41 all adopt existing technology, and their structures will not be described in detail in this embodiment.

[0043] The feeding assembly 40 includes a second pusher 42 and a feeding guide rail 43, both of which are mounted on the second frame 37. The second pusher 42 and the feeding guide rail 43 are distributed in parallel. A feeding frame 44 is connected between the output end of the second pusher 42 and the feeding guide rail 43. The second pusher 42 drives the feeding frame 44 to move along the feeding guide rail 43. A feeding tray 45 and a feeding profile 46 are mounted on the feeding frame 44. There are two feeding profiles 46 distributed on both sides of the feeding tray 45. Feeding push blocks 47 are installed on the feeding profiles 46. During feeding, the feeding tray 45 and the two feeding profiles 46 support the base plate and are pushed and moved by the feeding push blocks 47. The installation position of the feeding push blocks 47 on the feeding profiles 46 can be adjusted to meet the pushing needs of base plates of different specifications. In this embodiment, the second pusher 42 adopts, but is not limited to, a rodless cylinder. Other mechanisms are also applicable.

[0044] like Figure 1 and Figure 8 As shown, the pressing mechanism 7 includes a mounting frame 26, an upper fixing plate 27 and a lower fixing plate 28. The upper fixing plate 27 and the lower fixing plate 28 are both connected to the mounting frame 26 and are distributed at intervals. A pressing component is installed on the upper fixing plate 27 and a lifting component is installed on the lower fixing plate 28.

[0045] The pressing assembly includes a pressing actuator 29, an intermediate connecting plate 30, and a pressing plate 31. The fixed end of the pressing actuator 29 is mounted on the upper fixed plate 27. The output end of the pressing actuator 29 is connected to a first floating joint 32, which is connected to the intermediate connecting plate 30. The pressing plate 31 is connected to the intermediate connecting plate 30 through a rubber shock absorber. When pressing, the rubber shock absorber maintains a stable relative position to prevent damage caused by impact. Pressing guide rods are installed on the upper fixed plate 27 on both sides of the pressing actuator 29. The pressing guide rods pass through the upper fixed plate 27 and are connected to the intermediate connecting plate 30 to guide the lifting and lowering of the intermediate connecting plate 30. A guide sleeve can be installed at the position where the pressing guide rod passes through the upper fixed plate 27 to reduce the friction of the pressing guide rod.

[0046] The lifting assembly includes a lifting actuator 33 and a lifting plate 34. The fixed end of the lifting actuator 33 is connected to the lower fixed plate 28, and the output end of the lifting actuator 33 is connected to a second floating joint 35. The lifting plate 34 is connected to the lifting actuator 33 through the second floating joint 35. A positioning plate 36 is installed on the upper surface of the lifting plate 34. Lifting guide rods are installed on both sides of the lower fixed plate 28 and located on both sides of the lifting actuator 33. The lifting guide rods pass through the lower fixed plate 28 and are connected to the lifting plate 34 to guide the lifting of the lifting plate 34. A guide sleeve can be installed at the position where the lifting guide rod passes through the lower fixed plate 28 to reduce the friction of the lifting guide rod.

[0047] After the turnover tooling is in place, the blocking mechanism blocks it, the lifting actuator 33 drives the lifting plate 34 to rise, the positioning plate 36 positions the turnover tooling, and the pressing actuator 29 drives the intermediate connecting plate 30 and the pressing plate 31 to fall, applying a certain pressure to the formed paper and foam on the turnover tooling after they have been coated with glue and to the base plate, so that the base plate is firmly bonded to the paper and foam and prevents cracking.

[0048] like Figure 1 As shown, the die-cutting and unloading mechanism 8 includes a flatbed die-cutting machine 81, a linear module 82, and a robot arm 83. There are two linear modules 82 and two robot arms 83. The two linear modules 82 are installed on both sides of the flatbed die-cutting machine 81, and each linear module 82 is equipped with a corresponding robot arm 83. One linear module 82 drives the robot arm 83 to pick up the product to be cut from the turnover tooling and place it in the flatbed die-cutting machine 81. The other linear module 82 drives the robot arm 83 to take out the die-cut product from the flatbed die-cutting machine 81 and place it on the unloading conveyor line 10. By setting up two linear modules 82, each can be controlled and work independently, avoiding control confusion and reducing installation difficulty. In this embodiment, both the flatbed die-cutting machine 81 and the robot arm 83 adopt existing technology, and their structure will not be described in detail in this embodiment.

[0049] The working principle of this utility model is as follows:

[0050] In use, the front-end elevator 2 lifts the turnover tooling on the double-layer conveyor line 1 from the lower layer to the upper layer. The double-layer conveyor line 1 then conveys the turnover tooling to the paper feeding and forming mechanism 3. The paper feeding and forming mechanism 3 forms the paper and places it into the turnover tooling. Before the paper is formed, the corner folding component folds the corners to improve the quality of the paper forming. After the paper feeding is completed, the turnover tooling is conveyed to the foam feeding mechanism 4. The foam feeding mechanism 4 places the filling foam into the turnover tooling. The turnover tooling with the filling foam is then conveyed to the gluing mechanism 5. The gluing mechanism 5 applies glue to the paper and filling foam on the turnover tooling. After passing through the gluing mechanism 5, the turnover tooling is conveyed to the bottom plate feeding mechanism 6. The bottom plate is conveyed by the bottom plate feeding mechanism 6 onto the turnover tooling and is bonded to the paper and filling foam inside the turnover tooling. After the bottom plate is bonded... The turnover tooling is conveyed to the pressing mechanism 7 for pressing, so that the base plate and the foam filling of the paper sheet machine are well bonded. The turnover tooling is then conveyed to the die-cutting and unloading mechanism 8. The linear module 82, which is close to the double-layer conveyor line 1, drives the robot arm 83 to take out the product to be cut from the turnover tooling and place it in the flatbed die-cutting machine 81. After die-cutting, the robot arm 83, which is close to the double-layer conveyor line 1, takes out the product to be cut from the double-layer conveyor line 1 again. At the same time, the linear module 82, which is far away from the double-layer conveyor line 1, drives the robot arm 83 to take out the cut product from the flatbed die-cutting machine 81 and place it on the unloading conveyor line 10 to complete the unloading. After unloading the product, the turnover tooling moves to the rear lifting machine 9 and is transferred down to the lower layer of the double-layer conveyor line 1 by the rear lifting machine 9. The whole action is completed, realizing the production of the base tray.
