[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0040] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.
[0041] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0042] like Figures 1 to 5 As shown, a cardboard limiting device for a cardboard die-cutting machine according to an embodiment of the present invention includes:
[0043] The die-cutting machine body 1 is equipped with a paper feeding assembly 2 and a discharge assembly 3 for feeding and unloading paperboard. The die-cutting machine body 1 is also equipped with a die-cutting assembly 4 and a limiting assembly 5 for die-cutting and limiting the paperboard.
[0044] Limiting component 5, disposed on the die-cutting machine body 1, is used to limit the cardboard. Limiting component 5 includes:
[0045] The reset electromagnet 51 is fixedly installed on the main body 1 of the die-cutting machine;
[0046] The limiting plate 52 is rotatably fitted on the die-cutting machine body 1. The limiting plate 52 rotates relative to the die-cutting machine body 1 through the die-cutting assembly 4. The limiting plate 52 is magnetically fitted with the reset electromagnet 51.
[0047] Positioning plate 53 is rotatably fitted on limiting plate 52, and positioning plate 53 is slidably fitted with die-cutting machine body 1;
[0048] The positioning spring 54 is fixedly installed on the positioning plate 53;
[0049] The telescopic plate 55 is fixedly installed on the positioning spring 54, and the telescopic plate 55 is in sliding fit with the positioning plate 53.
[0050] The limit bracket 56 is fixedly installed on the telescopic plate 55.
[0051] Specifically, as a further embodiment of this utility model, the die-cutting component 4 includes:
[0052] Die-cutting assembly 4, disposed on the die-cutting machine body 1, is used for die-cutting cardboard. Die-cutting assembly 4 includes:
[0053] A die-cutting cylinder 41 is fixedly installed on the main body 1 of the die-cutting machine, and a die-cutting cutter 42 is fixedly installed on the output shaft of the die-cutting cylinder 41.
[0054] Mounting bracket 43 is fixedly mounted on die-cutting tool 42, and power electromagnet 44 is fixedly mounted on mounting bracket 43;
[0055] The power electromagnet 44 is magnetically engaged with the limiting plate 52;
[0056] In this embodiment of the utility model, during actual application, the paper feeding assembly 2 conveys the cardboard to the die-cutting machine body 1. The die-cutting cylinder 41 pushes the die-cutting cutter 42 downward, which causes the mounting frame 43 to drive the power electromagnet 44 downward synchronously. Due to the magnetic repulsion, the limiting plate 52 rotates, and the positioning plate 53 is pushed by the force of the rotation of the limiting plate 52. The limiting frame 56 presses and adheres to both sides of the cardboard. As the positioning plate 53 moves, the telescopic plate 55 will extend and retract into the positioning plate 53. Then, through the force of the positioning spring 54, the stability of the limiting frame 56 in limiting the cardboard is increased until the die-cutting cutter 42 completes the die-cutting of the cardboard. Subsequently, the die-cutting cutter 42 resets, and the reset electromagnet 51 and the limiting plate 52 repel each other magnetically, causing the limiting frame 56 to also reset.
[0057] By setting up the die-cutting component 4 and the limiting component 5, the two sides of the cardboard can be pressed and limited while the cardboard is being die-cut, thereby avoiding the cardboard from shifting position during die-cutting, increasing the accuracy of the die-cutting, and ensuring that the cardboard is in the center position of the die-cutting cutter 42 during die-cutting.
[0058] like Figure 2 and Figure 4 As shown, as a further embodiment of the present utility model, the die-cutting machine body 1 is provided with a first slide groove 11 for limiting the stroke of the positioning plate 53, and the die-cutting machine body 1 is also provided with a second slide groove 12 for limiting the stroke of the mounting bracket 43.
[0059] In this embodiment of the utility model, in actual application, the first slide groove 11 and the second slide groove 12 respectively limit the movement distance of the positioning plate 53 and the mounting bracket 43, thereby preventing excessive pressure on both sides of the cardboard and avoiding damage to the cardboard.
[0060] like Figure 3 and Figure 5 As shown, in a further embodiment of this utility model, the paper feeding assembly 2 includes:
[0061] A paper feeding motor 21 is fixedly installed on the main body 1 of the die-cutting machine, and a paper feeding roller 22 is fixedly installed on the output shaft of the paper feeding motor 21.
[0062] The paper feeding conveyor belt 23 is rotatably fitted on the die-cutting machine body 1, and the paper feeding conveyor belt 23 is rotatably fitted with the die-cutting machine body 1 through the paper feeding auxiliary roller;
[0063] Specifically, as a further embodiment of this utility model, the emission component 3 includes:
[0064] A paper discharge motor 31 is fixedly installed on the main body 1 of the die-cutting machine, and a paper discharge roller 32 is fixedly installed on the output shaft of the paper discharge motor 31.
[0065] The paper discharge conveyor belt 33 is rotatably fitted on the paper discharge roller 32, and the paper discharge conveyor belt 33 is rotatably fitted with the die-cutting machine body 1 through the paper discharge auxiliary roller;
[0066] In this embodiment of the present invention, in actual application, the paper feeding motor 21 feeds the cardboard through the paper feeding roller 22. After the cardboard is die-cut, the paper feeding conveyor belt 23 continues to feed the cardboard, which pushes the die-cut cardboard. The die-cut cardboard is then pushed onto the paper discharge conveyor belt 33 by the paper discharge motor 31 and the paper discharge roller 32. The paper discharge conveyor belt 33 then transports the die-cut cardboard.
[0067] like Figure 1 and Figure 5 As shown, as a further embodiment of the present utility model, it also includes a leveling component 6, which is disposed on the die-cutting machine body 1 and is used to press and level the cardboard. The leveling component 6 includes:
[0068] The fixing plate 61 is fixedly installed on the main body 1 of the die-cutting machine;
[0069] Gravity plate 62 is rotatably fitted onto fixed plate 61;
[0070] The fixed block 63 is rotatably fitted onto the gravity plate 62;
[0071] Gravity roller 64 is rotatably fitted onto fixed block 63;
[0072] The positioning rope 65 is connected to the fixing plate 61 and the gravity plate 62 respectively;
[0073] In this embodiment of the utility model, when the paper feeding conveyor belt 23 feeds the paperboard, the paperboard will be subjected to the squeezing force of the gravity roller 64, which will make the surface of the paperboard flattened. In addition, the gravity roller 64 can be rotated downwards to adjust according to the thickness of the paperboard, so that the paperboard is flattened well and the accuracy of paperboard die-cutting is improved.
[0074] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
