Therefore, the above terms should not be understood as limiting the present invention.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0023] Example 1: Please refer to Figure 1-12 A feeding device for a graphic cutting machine includes a frame 1, and further includes: a cutting unit 2 arranged on the frame 1, which processes the graphic cutting in sections through the cutting unit 2, and a loading rack 3 is arranged on one side of the frame 1, and a winding roller 4 is arranged on the loading rack 3, and a feeding unit 5 adapted to the winding roller 4 is arranged on the loading rack 3, and the feeding unit 5 is used to lift the winding roller 4 to feed the material, and; a feeding unit 6 arranged on the frame 1, and the feeding unit 6 is used to transport the material to the cutting unit 2 for processing; In this solution, the winding roller 4 is placed on the feeding unit 5, and the feeding unit 5 transfers the winding roller 4 to the loading mechanism 61, and the loading mechanism 61 prompts the winding roller 4 to the specified position and pulls the material to the feeding unit 6, which then uniformly transports the material to the cutting unit 2, and the cutting unit 2 cuts the material into sections for processing; Among them, the frame 1 is provided with a discharge mechanism 15 located below the cutting knife 13, and the discharge mechanism 15 is used to discharge the cut material. The discharge mechanism 15 includes: a carrier 16 is fixed on the frame 1, and a conveyor roller 17 is connected to the carrier 16 and the frame 1 for rotating together. The two conveyor rollers 17 are connected by a conveyor belt 18. A servo motor a19 is fixed on the carrier 16, and a sprocket 20 is fixed to one end of the output shaft of the conveyor roller 17 and the servo motor a19, and the sprocket 20 is meshed and driven by a chain 21. A discharge hopper is fixed on the carrier 16; It should be noted that the setting of the unloading mechanism 15 can ensure that the materials that have completed the cutting process are smoothly output to the pre-designated unloading position at a uniform and stable speed. This setting effectively avoids the unloading stagnation phenomenon caused by excessive accumulation of cut materials, thereby significantly reducing the bottleneck problem in the production process, not only optimizing the material cutting process, but also further improving the work efficiency of the entire unloading link, providing a strong guarantee for the cutting operation of graphic materials; In this solution, the unloading mechanism 15 is used to unload the material after cutting: the sprocket 20 is rotated by the drive of the servo motor a19, and the transmission effect between the sprocket 20 and the chain 21 is utilized to drive the conveyor roller 17 to rotate synchronously, and then drive the conveyor belt 18 to operate to unload the material after cutting.

[0024] Furthermore, the cutting unit 2 includes: a shaft a7 rotatably connected to the frame 1, and a drive motor a9 is fixed to the frame 1 through a support frame a8, the drive motor a9 is coaxially fixed to the shaft a7, at least two eccentric wheels 10 are fixed to the shaft a7, and a movable plate 11 is slidably connected to the frame 1, a hinge seat 12 hinged to the eccentric wheel 10 is fixed to the movable plate 11, a cutting knife 13 is installed on the movable plate 11, and the cutting knife 13 is installed between the movable plate 11 through a knife seat, which is convenient for replacing cutting tools of different specifications and models for cutting processing, and a pad 14 is fixed to the frame 1 directly below the cutting knife 13; Among them, a support 70 is fixed on the frame 1, and a guide rod 71 is fixed on the support 70. The movable plate 11 and the guide rod 71 are slidably arranged to penetrate each other, and the pad 14 is fixed to the guide rod 71. The addition of the guide rod 71 plays a guiding role for the movable plate 11, so that the movable plate 11 maintains relative stability when it moves up and down. It should be noted that the configuration of the cutting unit 2 achieves a high degree of reliability in the material cutting process. Specifically, by precisely adjusting the speed parameters of the drive motor a9 to achieve an optimal match with the required material length, the accuracy and stability of the cutting operation are ensured. This not only improves the cutting efficiency but also significantly reduces the cutting error, making the entire cutting process more reliable and efficient. In this solution, the cutting unit 2 is used to cut the material according to the following principle: the drive motor a9 is used to drive the shaft a7 to rotate synchronously, thereby driving the eccentric shaft to rotate, and the transmission force of the eccentric shaft and the hinge seat 12 is used to drive the movable plate 11 to move up and down along the guide rod 71, causing the cutting knife 13 to move synchronously with it, and the cutting knife 13 and the pad 14 are squeezed to complete the material cutting processing.

[0025] Furthermore, the feeding unit 6 includes: a feed roller a45 is rotatably connected to the frame 1, a drive motor b47 is fixed to the frame 1 through a support frame b46, the drive motor b47 is coaxially fixed to the feed roller a45, a pressing roller 48 is provided on the frame 1, and an adjusting member 49 adapted to the pressing roller 48 is provided on the frame 1, the adjusting member 49 is used to adjust the distance between the pressing roller 48 and the feed roller a45, a supporting plate 50 is fixed on the frame 1, and the supporting plate 50 is located between the pad 14 and the feed roller a45, a transmission shaft 51 is rotatably connected to the frame 1, the transmission shaft 51 and the feed roller a45 are connected for transmission via a pulley 52 and a belt 53, a feed roller b54 is rotatably connected to the frame 1, the feed roller b54 and the transmission shaft 51 are meshed for transmission via two transmission gears 55, and the feed roller a45 and the feed roller b54 turn in opposite directions; The adjusting member 49 includes: a slide groove 56 is provided on the frame 1, and the press roller 48 is slidably connected in the slide groove 56; a frame 57 is fixed on the frame 1; the press roller 48 is rotatably connected to a loading block 58 that is slidably connected to the frame 57; one of the loading blocks 58 is fixed to a slide rod 59 that slides through the frame 57; and the other loading block 58 is rotatably connected to a screw rod 60 that is threadedly connected to the frame 57; It should be noted that the configuration of the feeding unit 6 can ensure that the material to be cut is accurately transported to the cutting sampling area at a stable and uniform speed. During this process, the specially arranged feeding roller device can effectively smooth out any wrinkles that may appear on the surface of the material, thereby effectively avoiding the occurrence of poor cutting effects caused by wrinkles on the surface of the material. This comprehensive setting not only improves the material transmission efficiency, but also significantly improves the cutting quality. It should also be noted that by rotating the screw 60, the distance between the pressing roller 48 and the feeding roller a45 is adjusted by utilizing the thread transmission effect between the screw 60 and the frame 57, thereby ensuring that the material remains in contact with the feeding roller a45; In this scheme, the feeding unit 6 is used to transport the material to the cutting sampling principle: the feed roller a45 is rotated synchronously by the drive motor b47, so that the material is transported from between the feed roller a45 and the pressure roller 48 to the supporting plate 50, and the transmission action of the pulley 52 and the belt 53 is utilized to make the transmission shaft 51 rotate synchronously, and the meshing transmission action of the transmission gear 55 is utilized to drive the feed roller b54 to rotate, so as to achieve the purpose of the feed roller b54 and the feed roller b54 turning in opposite directions, and the feed roller b54 transports the material to the pad 14, and the material is cut and processed by the cutting unit 2.

[0026] In this solution, the specific process of cutting and loading graphic materials includes the following steps: The first step is to place the winding roller 4 containing the graphic material in the guide groove b24 and ensure that the winding roller 4 is in the restricted position by the limiting mechanism 25; In the second step, the feed unit 5 lifts the guide groove b24 and the synchronous linkage limit mechanism 25 releases the limit on the winding roller 4, causing the winding roller 4 in the guide groove b24 to slide onto the feeding mechanism 61 after being forced. The feeding mechanism 61 then flips the winding roller 4 to a suitable feeding position. In the third step, the staff manually pulls the material through the feeding unit 6 to the cutting processing area, and then feeds the material into the cutting unit 2 through the feeding unit 6; In the fourth step, the material is cut by the cutting unit 2, and the cut material is output by the conveyor belt 18 to complete the unloading work.

[0027] Example 2: Please refer to Figure 8 - Figure 12 This embodiment further explains the first embodiment, and the difference lies in a method of feeding the winding roller 4.

[0028] Specifically, the feeding unit 5 includes: a guide groove a22 fixed on the loading frame 3, the guide groove a22 is rotatably connected to the guide groove b24 through the rotating rod 23, the loading frame 3 is provided with a limiting mechanism 25 adapted to the winding roller 4, the limiting mechanism 25 is used to limit the winding roller 4 sliding in the guide groove b24, the guide groove b24 is provided with a groove 26, the loading frame 3 is provided with an inclined groove 27, and the inclined groove 27 is slidably connected to the extrusion block 28 abutting the groove 26, the loading frame 3 is provided with a connecting groove 29 connected to the inclined groove 27, and the extrusion block 28 is fixed with an arc block 30 slidably connected to the connecting groove 29, the loading frame 3 is rotatably connected to the screw rod 31 through the bearing seat, and the loading frame 3 is fixed with a servo motor b32 coaxially fixed with the screw rod 31. A transmission plate 33 is threadedly connected to the rod 31, and an extrusion inclined plate 34 is fixed on the transmission plate 33 to abut against the arc block 30, and a guide rod 35 is fixed on the loading frame 3 to allow the transmission plate 33 to slide through, and a mounting seat 36 is fixed on the loading frame 3. A tension spring 38 is hung between the mounting rod 37 and the mounting seat 36 on the arc block 30, and a limit block 66 is fixed on the guide groove a22. By adding the limit block 66, it plays a limiting role on the winding roller 4, which can prevent the winding roller 4 from moving too far. A limiting groove 68 is opened on the frame 1, and a limiting plate 69 is fixed on the extrusion inclined plate 34 to be slidably connected to the limiting groove 68. The setting of the limiting plate 69 plays a limiting role on the extrusion inclined plate 34, ensuring that the stroke of the extrusion inclined plate 34 moves within the limiting groove 68; The limiting mechanism 25 comprises: a rotating shaft 39 is rotatably connected to the loading frame 3 through a mounting block, and at least two channels 40 are provided on the loading frame 3, a limiting rod 41 is fixed on the rotating shaft 39 and slidably connected in the channel 40, and one end of the limiting rod 41 is provided with a positioning groove 42 which is engaged with the winding roller 4, a pinion 43 is fixed on the rotating shaft 39, and a rack 44 which is meshed with the pinion 43 is fixed on the transmission plate 33. Through the setting of the limiting mechanism 25, the position of the winding roller 4 is restricted to prevent the winding roller 4 from accidentally sliding to the feeding area of ​​the feeding mechanism 61, and when the feeding unit 5 sends the winding roller 4 to the feeding mechanism 61, the limiting state of the winding roller 4 can be synchronously released, and when the guide groove b24 and the loading frame 3 are in a horizontal state, the winding roller 4 is limited. A limiting seat adapted to the limiting rod 41 is fixed on the loading frame 3 to ensure that the maximum rotation angle of the limiting rod 41 is ninety degrees. It should be noted that the number of teeth on the rack 44 is one-fourth the number of teeth on the pinion 43, ensuring that the maximum rotation angle of the limit rod 41 is ninety degrees. When the guide groove b24 and the carrier 3 are in a horizontal fit, the limit rod 41 is in a vertical state to limit the winding roller 4. When the guide groove b24 rotates, the limit rod 41 can be linked to flip ninety degrees to release the limit state of the winding roller 4. It should also be noted that, through the provision of the feeding unit 5, the winding roller 4 placed flat on the material carrier 3 can be efficiently and accurately fed into the feeding mechanism 61. This process not only greatly reduces the labor intensity of the staff in the process of carrying and placing the winding roller 4, effectively reducing the physical burden of the staff, but also can significantly improve the efficiency of material loading, making the entire loading process smoother and faster. Compared with the traditional loading method that relies on manual operation, this device shows a high degree of automation, which not only reduces the manual operation links, but also greatly reduces the error rate caused by human factors, thereby ensuring the accuracy and stability of the loading process. In this solution, the feeding unit 5 is used to send the winding roller 4 to the loading mechanism 61. The principle is: first, the winding roller 4 needs to be placed stably inside the guide groove b24, and ensure that the winding roller 4 is in the limited state of the limiting mechanism 25, adjust the angle of the load-bearing arm 63, ensure that the load-bearing arm 63 and the loading rack 3 are in a mutually horizontal state, and the servo motor b32 is driven to make the screw rod 31 rotate synchronously, and the threaded transmission effect between the screw rod 31 and the transmission plate 33 is utilized, and the guiding effect of the transmission plate 33 and the guide rod 35 is coordinated to ensure that the transmission plate 33 is subjected to force and performs a translational movement along the guide rod 35, thereby driving the extrusion inclined plate 34 synchronously. The movement is carried out by utilizing the extrusion transmission effect between the inclined surface of the extrusion ramp 34 and the arc block 30, thereby driving the extrusion block 28 to move along the opening direction of the inclined groove 27, and utilizing the arc block 30 to be squeezed with the groove 26 on the guide groove b24. At this time, the tension spring 38 is in a stretched state, and utilizing the elastic effect of the tension spring 38, not only ensures that the arc block 30 and the extrusion ramp 34 are always in a fit state, but also can play a role in resetting the arc block 30, and can drive the guide groove b24 to flip a certain angle along the axis of the rotating rod 23, causing the winding roller 4 stored in the guide groove b24 to slide into the card slot 65 on the load-bearing arm 63 under force.

[0029] Furthermore, a feeding mechanism 61 adapted to the winding roller 4 is provided on the frame 1. The feeding mechanism 61 includes: a load-bearing arm 63 rotatably connected to the frame 1 via a central axis 62, a cylinder 64 rotatably connected to the frame 1 via a rod a, a rod b rotatably connected to the output end of the cylinder 64 is fixed on the load-bearing arm 63, and a slot 65 for engaging the winding roller 4 is provided on the load-bearing arm 63; Specifically, a limiting rod connected to the card slot 65 is inserted on the load-bearing arm 63 to prevent the winding roller 4 from deviating and to limit the winding roller 4 in the card slot 65. A round rod 67 for limiting the load-bearing arm 63 is fixed on the frame 1. The addition of the round rod 67 limits the load-bearing arm 63 and ensures that the maximum downward rotation angle of the load-bearing arm 63 is forty-five degrees. It should be noted that, through the configuration of the feeding mechanism 61, the present device can efficiently and accurately lift and flip the winding roller 4 to the optimal angle position, thereby smoothly performing the feeding operation. Compared with the traditional method of relying on manual handling for feeding, the present device significantly reduces the consumption of manual labor and avoids heavy physical labor. At the same time, it greatly improves the speed of material feeding and optimizes the efficiency of the entire production process. This automated feeding mechanism not only reduces the labor burden of workers, but also ensures the stability and accuracy of the feeding process. In this solution, the feeding mechanism 61 is used to flip the winding roller 4 to the appropriate feeding position. The principle is: first, ensure that the load-bearing arm 63 and the loading frame 3 remain parallel to each other. When the winding roller 4 is engaged with the slot 65 in the load-bearing arm 63, the limiting rod is inserted into the limit position to limit the position of the winding roller 4. Through the drive of the cylinder 64, the load-bearing arm 63 is subjected to force and flipped along the axial direction of the center axis 62, thereby flipping the winding roller 4 to the appropriate feeding angle position.
