[0028] The following referenceFigures 1 to 2 Describe the buffer mechanism of the embodiment of the present utility model and the flat die-cutting device having the same.

[0029] As Figure 1 As shown, the buffer mechanism according to the embodiment of the present utility model includes: a mounting frame 100, a guiding member 200, a guiding roller assembly 300, and an elastic member 400; the guiding member 200 is erected on the mounting frame 100; the guiding roller assembly 300 is vertically slidably connected to the guiding member 200; the elastic member 400 is connected to the guiding roller assembly 300 and is used to provide an elastic force for lifting the guiding roller assembly 300.

[0030] It can be understood that such a buffer mechanism includes a mounting frame 100, a guiding member 200, a guiding roller assembly 300, and an elastic member 400; during use, when the die-cutting machine presses down on the material tape for flat die-cutting, the material tape can drive the guiding roller assembly 300 to press down, the guiding roller assembly 300 can descend along the guiding member 200 and deform the elastic member 400, and the elastic member 400 generates an elastic force for lifting the guiding roller assembly 300. Subsequently, during the process of feeding the material tape, the downward pressure of the material tape on the guiding roller assembly 300 decreases, so that the guiding roller assembly 300 can drive the material tape to rise under the action of the elastic force of the elastic member 400, thereby continuing to tighten the material tape, preventing the material tape from shifting left and right. When the die-cutting machine presses down on the material tape for flat die-cutting again, the material tape presses down and the guiding roller assembly 300 descends, so as to always keep the material tape taut, avoid the offset of the material tape in the width direction during the die-cutting process, and further improve the material utilization rate and reduce the phenomena of edge waste and defective products; therefore, the buffer mechanism of the present application can cooperate with the die-cutting machine to perform flat die-cutting on the material tape, play a role in flexibly tightening the material tape, reduce the offset of the material tape in the width direction, and improve the material utilization rate.

[0031] It can be understood that a first connecting member 500 and a limiting member 600 are further included. The limiting member 600 and the first connecting member 500 are respectively arranged at the upper end and the lower end of the guiding member 200, and the guiding roller assembly 300 is limited between the limiting member 600 and the first connecting member 500. For example, as Figure 1 As shown, in this embodiment, by arranging a limiting member 600 at the upper end of the guiding member 200 and a first connecting member 500 at the lower end, the lifting height of the guiding roller assembly 300 is limited between the limiting member 600 and the first connecting member 500.

[0032] It can be understood that the elastic member 400 is a tension spring. For example, as Figure 1 As shown, in this embodiment, the elastic member 400 is a tension spring. In some other embodiments, the elastic member 400 can also be set as a compression spring.

[0033] It can be understood that the elastic member 400 is connected to the limiting member 600 and the guiding roller assembly 300. For example, as Figure 1As shown, in this embodiment, the tension spring is arranged between the limiting member 600 and the guide roller assembly 300. Therefore, when the guide roller assembly 300 descends under the pressing force of the material tape, the tension spring can be driven to elongate. Thus, when the pressing force of the material tape on the guide roller assembly 300 decreases, the guide roller assembly 300 can rise under the elastic force of the tension spring.

[0034] It can be understood that the guide roller assembly 300 includes a guide shaft 310 and a rotating roller 320. The end of the guide roller is fixedly arranged on the first connecting member 500, and the rotating roller 320 is rotatably connected to the guide shaft 310. For example, as Figure 2 shown, in this embodiment, the guide roller assembly 300 includes a guide shaft 310 and a rotating roller 320 rotatably connected to the guide shaft 310. Thus, when the material tape feeds through the guide roller assembly 300, the rotating roller 320 can be driven to rotate, thereby reducing the friction force received by the material tape, reducing the wear of the material tape, and also increasing the feeding speed.

[0035] It can be understood that there are two guide members 200 arranged side by side, and both are guide posts. For example, as Figure 1 shown, in this embodiment, the guide member 200 is a guide post, and two are provided, thereby improving the stability and smoothness of the lifting of the guide roller assembly 300.

[0036] It can be understood that it further includes a second connecting member 700 and a locking member. The second connecting member 700 is arranged below the first connecting member 500. The guide member 200 is connected to the mounting frame 100 through the second connecting member 700. The mounting frame 100 is provided with a waist-shaped hole 110, and the second connecting member 700 is provided with a connecting hole. The locking member connects the connecting hole and the waist-shaped hole 110, and can adjust the height and horizontal position of the second connecting member 700. For example, as Figure 2 shown, in this embodiment, by connecting the connecting hole of the second connecting member 700 and different positions of the waist-shaped hole 110 of the mounting frame 100 through the locking member, the position of the second connecting member 700 is adjusted, and further the position of the guide roller assembly 300 in the horizontal and vertical directions is adjusted to avoid interference with other components when used in cooperation with a die-cutting machine.

[0037] It can be understood that the mounting frame 100 is provided with a weight-reducing hole 120. For example, as Figure 2 shown, in this embodiment, the weight-reducing hole 120 provided on the mounting frame 100 can reduce the overall weight of the buffer mechanism, so that when it is installed on the corresponding equipment for use, the stability during use can be improved.

[0038] The flat die-cutting device according to the second aspect embodiment of the present invention includes the buffer mechanism in the first aspect embodiment, and further includes a die-cutting machine. The buffer mechanism is arranged on the material tape input side of the die-cutting machine.

[0039] It can be understood that such a flat die-cutting device includes a die-cutting machine and a buffer mechanism used in cooperation with the die-cutting machine. Therefore, the buffer mechanism can improve the yield rate of the products die-cut by the die-cutting machine, reduce the edge waste, and improve the material utilization rate.

[0040] It can be understood that it further includes a feeder and a rewinder. The feeder, the buffer mechanism, the die-cutting machine, and the rewinder are arranged in sequence along the feeding direction of the material tape. The feeder is used for intermittent feeding, and the rewinder is used for winding the material tape. For example, in this embodiment, the feeder, the buffer mechanism, the die-cutting machine, and the rewinder are arranged in sequence along the feeding direction of the material tape. When the die-cutting machine presses down on the material tape for flat die-cutting, the material tape presses down on the guide roller assembly 300 in the buffer mechanism. Subsequently, the rewinder winds up, and the feeder feeds the material tape in the direction of the buffer mechanism, and the pressure of the material tape on the guide roller assembly 300 decreases. Thus, the guide roller assembly 300 can drive the material tape to move upward under the action of the elastic member 400, so as to realize the tensioning of the material tape. Subsequently, the die-cutting machine continues to press down on the material tape for die-cutting, and the material tape is tensioned again and presses down on the guide roller assembly 300. Therefore, such a flat die-cutting device can improve the tensioning degree of the material tape, thereby avoiding the deviation of the material tape in the width direction, and further improving the material utilization rate and the yield rate of the die-cutting by the die-cutting machine.

[0041] The above has described the embodiments of the present application in detail with reference to the drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application. In addition, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
