Description

A paper feeding path guiding device Technical Field

[0001] This utility model relates to the field of paperboard guiding technology, and more specifically, to a paper feeding path guiding device. Background Technology

[0002] In the production of cardboard packaging, the die-cutting machine is one of the essential pieces of equipment. It is used to precisely cut and creasing cardboard using die-cutting rollers to meet different packaging needs. However, the fiber orientation of the cardboard has a significant impact on its resistance to deformation. When cardboard is transported into the die-cutting machine along the fiber direction (co-grain direction), its strength is higher and deformation is smaller; conversely, if the cardboard enters the die-cutting machine transversely (cross-grain direction), its strength is lower and it is more prone to deformation. Therefore, optimizing the paper feed direction so that its fiber direction is consistent with the transport direction and thus with the cutting direction of the die-cutting machine can effectively reduce deformation during the cutting process, improve product stability, and increase the pass rate of subsequent processing.

[0003] Traditional methods typically involve manual observation and stopping the equipment to manually adjust the cardboard, which is labor-intensive and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a paper feeding path guiding device that optimizes the paper feeding direction of the cardboard, adjusting the cardboard from the cross-grain direction to the grain direction, thereby aligning its fiber direction with the transport direction and thus with the cutting direction of the die-cutting machine.

[0029] Furthermore, the detection component includes a spring 9 with one end connected to the outside of the sliding sleeve 8, and a receiving plate 10 connected to the other end of the spring 9. A pressure sensor 11 electrically connected to the controller is provided between the receiving plate 10 and the inner wall of the side plate 4. The pressure detection mechanism corresponding to the upper extrusion roller 5 is located above the sliding sleeve 8, and the pressure detection mechanism corresponding to the lower extrusion roller 5 is located below the sliding sleeve 8.

[0030] Furthermore, the texture reversing table 2 includes a base 14 and a turning table 15 rotatably connected above the base 14 via a rotating assembly. The turning table 15 has multiple mounting slots 16 with top openings arranged inside along the transport direction of the cardboard. Multiple first mounting plates 17 and second mounting plates 18 are slidably disposed inside the mounting slots 16, with the first mounting plates 17 and second mounting plates 18 spaced apart and staggered. A second transport roller 19 is rotatably connected to the top of the first mounting plate 17, and the second transport roller 19 is driven to rotate by a first motor. The rotation direction of the second transport roller 19 is the same as the transport direction of the cardboard. The top of the second mounting plate 18 is provided with multiple rollers 21 driven to rotate by a second motor 20. The rotation direction of the rollers 21 is perpendicular to the transport direction of the cardboard. A switching assembly is provided below the first mounting plate 17 and the second mounting plate 18 to switch between raising and lowering them. The first motor and the second motor 20 are electrically connected to the controller.

[0031] Furthermore, the rotating assembly includes a drive ring 22 disposed below the steering platform 15. The drive ring 22 is rotatably disposed inside the base 14. The inner side of the drive ring 22 is provided with drive teeth. The base 14 is provided with a third motor 23 electrically connected to the controller. The output end of the third motor 23 is provided with a gear 24 that cooperates with the drive teeth.

[0032] Furthermore, the switching assembly includes a mounting rod 25 rotatably disposed inside the turntable 15. The mounting rod 25 is driven to rotate by a fourth motor 26 electrically connected to the controller. The fourth motor 26 is connected to the mounting rod 25 via a transmission belt mechanism. A plurality of first cams 27 and second cams 28 are coaxially fixedly sleeved on the outside of the mounting rod 25. The first cams 27 and second cams 28 are arranged alternately at intervals. The outer peripheral surfaces of the first cams 27 and second cams 28 respectively abut against the bottom of the first mounting plate 17 and the second mounting plate 18. The included angle between the protrusions of the first cams 27 and the protrusions of the second cams 28 is 180°.

[0033] Furthermore, it also includes a die-cutting machine docking transport table 29, on the top of which a plurality of third transport rollers 30 are rotatably mounted. The first end of the die-cutting machine docking transport table 29 is docked with the tail end of the texture reversing table 2, and the tail end of the die-cutting machine docking transport table 29 is docked with the transport inlet of the die-cutting machine.

[0034] Furthermore, the third transport roller 30, located at the front end of the die-cutting machine docking transport table 29, is driven to rotate by a fourth motor 26 electrically connected to the controller.

[0035] Furthermore, the first transport roller 3 located at the front end of the texture detection transport table 1 is driven to rotate by a fifth motor electrically connected to the controller.

[0036] In use, the fifth motor drives the corresponding first transport roller 3 to rotate, moving the cardboard and pressing it between the two extrusion rollers 5. The cardboard overcomes the elastic force of the spring 9 and applies force to the pressure sensor 11. If the cardboard is in the same direction as the grain, it will apply a constant pressure to the pressure sensor 11 during its forward movement. If the cardboard is in the opposite direction, it will apply fluctuating pressure to the pressure sensor 11 during its forward movement (because the cardboard has a certain softness, the pressure will fluctuate when the extrusion roller 5 rolls over the opposite grain). If the cardboard is detected to be in the same direction as the grain, when the cardboard reaches the turntable 15, the second transport roller 19 at the top of the first mounting plate 17 drives the cardboard to continue moving forward under the drive of the first motor. The cardboard passes through the third transport roller 30 at the top of the die-cutting machine docking transport table 29 and enters the die-cutting machine for die-cutting operation. If the cardboard is detected to be in the cross-grain direction, after the cardboard detaches from the final squeeze roller 5, it reaches the top of the second transport roller 19 of the turntable 15. At this point, the second transport roller 19 stops rotating, and then the third motor 23 rotates, causing the gear 24 to drive the drive ring 22 to rotate 90°, which in turn drives the turntable 15 to rotate 90° relative to the base 14. From this point, the cardboard changes from cross-grain to longitudinal grain. Then, the fourth motor 26 drives the mounting rod 25 to rotate 180°. At this time, all the first cams 27 rotate synchronously, causing all the first mounting plates 17 to descend synchronously and detach from the bottom surface of the cardboard. The second cams 28 rotate synchronously, pushing the second mounting plate 18 upward so that the roller 21 abuts against the bottom surface of the cardboard. Then, under the rotation of the second motor 20, the roller 21 drives the cardboard to continue moving forward in the longitudinal grain direction.

[0037] It is worth mentioning that the controller uses an S7-200 SMART industrial PLC controller. Additionally, the fourth motor 26 and the fifth motor provide increased driving force for the cardboard's forward movement.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
