[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a conveying structure for double-layer cardboard pressing, including a support frame 1, which supports the entire equipment. A conveyor belt 2 is installed inside the support frame 1 to convey the cardboard. A protective shell 10 is fixedly connected to the bottom of the support frame 1 to protect internal parts from damage. A limiting mechanism is installed inside the protective shell 10 to adjust the cardboard conveying sequence for subsequent processing. A loss-reducing mechanism is installed outside the limiting mechanism to prevent damage during adjustment. To prevent damage to the cardboard, a positioning post 7 is fixedly connected to the top of the bracket 1. The positioning post 7 allows the rotating wheel 6 to be adjusted according to the cardboard thickness. A slider 26 is slidably connected to the outside of the positioning post 7, facilitating the adjustment of the crossbar 5. A locking mechanism is installed on the outside of the slider 26 to lock the crossbar 5. The limiting mechanism includes a transmission component, a moving component, and a stabilizing component. The transmission component includes rack one 14 and rack two 15, which are slidably connected inside the protective shell 10. The limiting mechanism uses rack one 14 and rack two 15 to... Adjustable according to the width of the cardboard, the protective shell 10 has a gear 16 rotatably connected inside, which drives rack 14 and rack 2 15 to move. Rack 14 and rack 2 15 mesh with gear 16. A motor 11 is fixedly connected to the bottom of the protective shell 10, which drives gear 16 to rotate. The output end of motor 11 is fixedly connected to gear 16. The moving component includes two moving plates 8, which are slidably connected inside the protective shell 10. Other components are supported by the moving plates 8. One of the moving plates 8 is fixedly connected to a gear on its outside. The first rack 14 and the second rack 15 are fixedly connected to the outside of the other movable plate 8. The movable plate 8 is fixedly connected to the outside of the connecting frame 9. The clamping block 18 is connected to the connecting frame 9 for movement. The clamping block 18 is fixedly connected to the outside of the connecting frame 9 for limiting and adjusting the cardboard. The stabilizing component includes a fixing rod 12, which is fixedly connected to the outside of the movable plate 8. The first rack 14 and the second rack 15 are both provided with grooves 13. The fixing rod 12 and the grooves 13 are interlocked. The fixing rod 12 moves in the grooves 13 to make the limiting mechanism more stable.

[0034] Reference Figure 1 , Figure 2 and Figure 5The latching mechanism includes a plug-in assembly and a return assembly. The plug-in assembly includes a housing 27, which protects the internal parts from damage. The housing 27 is fixedly connected to the middle of the slider 26. A pin 28 is slidably connected inside the housing 27 to fix the crossbar 5. The positioning post 7 has several insertion holes 25 in the middle. The pin 28 and the insertion holes 25 are interlocked. The pin 28 can be inserted into the corresponding insertion hole 25 as needed. The return assembly includes a limiting plate 17, which is fixedly connected to the outside of the pin 28. The limiting plate 17 can prevent the pin 28 from being ejected due to excessive elasticity of the second spring 29, which would cause damage to the equipment. The second spring 29 is sleeved on the outside of the pin 28, which allows the pin 28 to return to the center quickly, improving the user's work efficiency.

[0035] Reference Figure 1 and Figure 4 The damage reduction mechanism includes a sliding component and a telescopic component. The sliding component includes a fixed block 19, which is fixedly connected to the inside of the clamping block 18 and supports other components. A movable block 20 is slidably connected inside the fixed block 19, and a movable rod 22 is fixedly connected to the middle of the movable block 20. A pulley 21 is rotatably connected to the outside of the movable rod 22, which reduces damage to the cardboard. The telescopic component includes a spring 23, which is fixedly connected inside the fixed block 19. The spring 23 allows the movable block 20 to quickly return to its original position and move together with the pulley 21. A movable groove 24 is provided inside the fixed block 19. Spring 23 is fixedly connected to movable block 20, which is slidably connected to the outside of movable groove 24. The cardboard is squeezed by pulley 21, which moves movable block 20 in movable groove 24 while squeezing spring 23. This reduces damage to the cardboard and adjusts the cardboard position. An auxiliary block 4 is fixedly connected to the top of bracket 1, and a crossbar 5 is fixedly connected to the outside of the auxiliary block 4. The crossbar 5 is fixed by the auxiliary block 4. A rotating wheel 6 is rotatably connected to the outside of the crossbar 5. The rotating wheel 6 squeezes the cardboard by rotating on the crossbar 5. A processing box 3 is fixedly connected to the top of bracket 1. The cardboard is initially processed and transported by the processing box 3.

[0036] Working principle: First, when the conveyor belt 2 transports cardboard, the cardboard may become misaligned on the conveyor belt 2, affecting the next processing step. At this time, the motor 11 is started, which will drive the gear 16 connected to it to rotate. At this time, the rack 14 and rack 2 15 meshing with the gear 16 will move horizontally and drive the moving plate 8 to move. At this time, the connecting frame 9 connected to the moving plate 8 will move closer to each other, and the clamping block 18 connected to the connecting frame 9 will move and move closer, finally limiting the cardboard according to the size of the cardboard. At the same time, the pulley 21 inside the clamping block will assist the cardboard to move. The fixed blocks 19 on both sides of the pulley 21 are equipped with spring 23. The moving rod 22 connected to the pulley 21 will drive the moving block 20 sliding in the moving groove 24 to squeeze the spring 23, so that the cardboard can be limited and adjusted without being damaged by the rigidity of the equipment.

[0037] Secondly, when it is necessary to press cardboard of different thicknesses, the pressing thickness of the rotating wheel 6 can be adjusted by adjusting the height of the crossbar 5. At this time, the pin 28 can be pulled, and the limiting plate 17 outside the pin 28 will move with the pin 28 and squeeze the spring 29 outside the pin 28. When the pin 28 is completely pulled out from the insertion hole 25 on the positioning post 7, the height of the crossbar 5 is adjusted so that the slider 26 slides along the positioning post 7. When the desired height is reached, the hand pulling the pin 28 is released. Due to the elasticity of the spring 29, the pin 28 will immediately return to the center and be inserted into the corresponding insertion hole 25. Due to the effect of the limiting plate 17, the pin 28 will be prevented from being ejected due to excessive elasticity, which would cause damage to the parts.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
