[0033] The present application is further described in detail below in conjunction with the accompanying drawings.
[0034] See also Figure 1-5 As shown, a label paper die-cutting mechanism for convenient waste discharge is shown, which includes a machine base 8, a lower die 1 arranged on the machine base 8, an upper die 2 arranged above the lower die 1 and capable of being lifted and lowered, and a driving module 3 for driving the upper die 2 to lift and lower. The driving module 3 is a cylinder arranged on the machine base 8. Four guide rods 9 are also arranged at the peripheral end of the lower die 1, and the peripheral end of the upper die 2 is slidably connected with the four guide rods 9. A first die-cutting piece 4 is arranged on the upper die 2, and the first die-cutting piece 4 includes a die-cutting groove 41 opened at the bottom of the upper die 2, a waste discharge groove 42 arranged in the upper die 2 and one end of which is connected to the die-cutting groove 41, and a waste discharge port 43 formed at the other end of the waste discharge groove 42. A second die-cutting piece 5 is arranged on the lower die 1, and the second die-cutting piece 5 includes a die-cutting knife 51 arranged at the top of the lower die 1 and located directly below the die-cutting groove 41.
[0035] When the label paper passes between the upper die 2 and the lower die 1, the upper die 2 descends, and the label paper is die-cut with the cooperation of the die-cutting groove 41 and the die-cutting knife 51. The die-cutting waste will be pushed into the waste discharge groove 42 by the die-cutting knife 51. The die-cutting waste generated after multiple die-cutting will adhere to each other under the multiple pushing actions of the cutting knife and gradually be discharged from the waste discharge port 43. There is no need to stop the machine specifically to clean the die-cutting waste, which not only reduces the workload of workers but also improves the die-cutting efficiency.
[0036] In this embodiment, combined with Figure 3 As shown, the waste discharge groove 42 extends in the vertical direction and its length is greater than the length of the die cutting knife 51. The vertically extending waste discharge groove 42 can effectively eliminate the dead corner of waste discharge, and prevent the die cutting waste from remaining in the waste discharge groove 42 and affecting the subsequent waste discharge; at the same time, the length of the waste discharge groove 42 is greater than the length of the die cutting knife 51, which can effectively prevent the die cutting knife 51 from directly pushing the die cutting waste out of the waste discharge groove 42, so that the waste discharge groove 42 can collect and discharge the die cutting waste.
[0037] In this embodiment, combined again Figure 3 As shown, the upper die 2 includes an upper die base 21, an upper die block 22 disposed at the bottom of the upper die base 21, a waste discharge groove 42 is disposed through the upper die block 22, and a waste discharge port 43 and a die-cutting groove 41 are respectively provided at the upper and lower sides of the upper die block 22. Among them, there are multiple first die-cutting pieces 4, and there are also multiple die-cutting grooves 41, waste discharge grooves 42 and waste discharge ports 43 constituting the first die-cutting pieces 4. The multiple die-cutting grooves 41 are arranged at intervals along the length direction of the upper die block 22.
[0038] like Figure 3 and Figure 5As shown, a temporary storage groove 6 is provided at the top of the upper module 22 along the length direction thereof, and a waste outlet 43 is provided at the bottom of the temporary storage groove 6. A plurality of waste outlets 43 are provided in the temporary storage groove 6 at intervals along the length direction of the temporary storage groove 6. A large number of die-cutting wastes that are bonded to each other and output from the waste outlets 43 can be temporarily stored in the temporary storage groove 6, so that the die-cutting wastes are prevented from being scattered around after being output from the waste outlets 43, so that workers can clean up the die-cutting wastes after they have accumulated to a certain amount, which greatly saves labor costs.
[0039] In this embodiment, if Figure 1 and Figure 3 As shown, a waste taking groove 7 is provided on the upper die base 21, and the waste taking groove 7 is arranged to penetrate the upper die base 21 along the vertical direction, and the projection of the waste outlet 43 on the upper die base 21 is located in the waste taking groove 7. The waste taking groove 7 can accommodate die-cutting waste, so that workers can conveniently take out the die-cutting waste discharged from the waste outlet 43 through the waste taking groove 7, thereby improving the cleaning efficiency of the die-cutting waste; at the same time, the diameter of the upper end notch of the waste taking groove 7 is larger than the diameter of the lower end notch, so that it is convenient for workers to put their hands into the waste taking groove 7 and clean the die-cutting waste.
[0040] In this embodiment, a soft first anti-collision layer 23 is attached to the bottom of the upper module 22 , and a communication port communicating with the die-cutting groove 41 is opened on the first anti-collision layer 23 .
[0041] like Figure 2 and Figure 5 As shown, the lower die 1 includes a lower die base 11, a lower module 12 disposed on the lower die base 11, a die cutter 51 is disposed on the top of the lower module 12, and the second die-cutting member 5 includes a plurality of die cutters 51 arranged at intervals along the length direction of the lower module 12. The projection of the upper module 22 on the lower die base 11 overlaps with the lower module 12, and the plurality of die cutters 51 correspond one to one with the plurality of die-cutting grooves 41. A soft second anti-collision layer 13 is attached to the top of the lower module 12, and the die cutter 51 is disposed through the second anti-collision layer 13.
[0042] The first anti-collision layer 23 and the second anti-collision layer 13 are both made of rubber material.
[0043] The implementation principle of a label paper die-cutting mechanism in the embodiment of the present application is:
[0044] The label paper is conveyed through the label paper die-cutting mechanism. When the label paper is located between the upper die 2 and the lower die 1, the upper die 2 descends, and the label paper is first die-cut in cooperation with the die-cutting groove 41 and the die-cutting knife 51. The waste after die-cutting will be pushed into the waste discharge groove 42 by the die-cutting knife 51.
[0045] Then the label paper is continuously conveyed forward, the upper die 2 is lifted and lowered for multiple times, the die-cutting groove 41 and the die-cutting knife 51 cooperate with each other and perform multiple die-cutting on the label paper, and the die-cutting waste generated after multiple die-cutting is bonded to each other under the multiple pushing actions of the cutter and gradually discharged from the waste outlet 43;
[0046] The die-cutting waste output from the waste outlet 43 is temporarily stored in the temporary storage tank 6, and then the gradually increasing die-cutting waste enters and is accommodated in the waste taking tank 7. When the die-cutting waste in the waste taking tank 7 accumulates to a certain amount, the worker reaches into the waste taking tank 7 and takes out the die-cutting waste.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
