Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0030] In the related art, the x-axis asynchronous jump distance of the existing feeding device can only reach the level of 1.5mm±0.8mm, and the utilization rate of the die-cutting material is relatively low, resulting in serious waste of die-cutting materials and excessively high material costs.

[0031] See also Figure 1 , Figure 1 It is a schematic diagram of the three-dimensional structure of a feeding device 100 under an embodiment of an embodiment of the present utility model. The embodiment of the present utility model provides a feeding device 100, including a mounting seat 10, a feeding roller shaft 20, a pressure roller shaft 30 and a supporting assembly 40. The mounting seat 10 is used to be set on a support surface. The feeding roller shaft 20 can be relatively rotatably set on the mounting seat 10, and the feeding roller shaft 20 is used to wind the die-cutting material. The pressure roller shaft 30 can be relatively rotatably set on the mounting seat 10 and is opposite to the feeding roller shaft 20. The supporting assembly 40 is set on the mounting seat 10 and connected to the pressure roller shaft 30. The supporting assembly 40 applies an elastic force toward the feeding roller shaft 20 to the pressure roller shaft 30, so that the pressure roller shaft 30 elastically resists the die-cutting material.

[0032] Specifically, the support surface can be the ground, the surface of other equipment, a wall, etc. The feed roller 20 and the press roller 30 are parallel to each other, and the axis about which the feed roller 20 rotates relative to the mounting base 10 is parallel to the axis about which the press roller 30 rotates relative to the mounting base 10. The support assembly 40 can be made of an elastic organic material such as rubber, silicone, or sponge to apply an elastic force toward the feed roller 20 to the press roller 30. The support assembly 40 can also be made of an elastic metal material such as a spring, a reed, or a shrapnel to apply an elastic force toward the feed roller 20. In this embodiment, the press roller 30 is located on the top side of the feed roller 20 in the vertical direction, and the support assembly 40 applies a downward elastic force to the press roller 30. In other embodiments, the press roller 30 can also be located on the bottom side of the feed roller 20 in the vertical direction, and the support assembly 40 applies an upward elastic force to the press roller 30. Alternatively, the nip roller shaft 30 is located on one side of the feed roller shaft 20 in the horizontal direction, and the supporting assembly 40 applies a horizontal elastic force toward the feed roller shaft 20 to the nip roller shaft 30 .

[0033] As you can understand, the support assembly 40 elastically clamps the nip roller 30 and feed roller 20 on either side of the die-cut material, compacting the material. This significantly reduces the x-axis asynchronous jump during transport. This allows the x-axis asynchronous jump to be reduced to 0.8mm ± 0.3mm, resulting in higher material utilization and lower material costs.

[0034] By setting the pressure roller shaft 30 and the supporting component 40, the supporting component 40 applies an elastic force to the pressure roller shaft 30 toward the feed roller shaft 20, and the pressure roller shaft 30 can elastically support the die-cutting material on the feed roller shaft 20, so that the die-cutting material is in the required compact state, reducing the x-direction asynchronous jump distance during processing, improving the utilization rate of the die-cutting material, and thus reducing costs.

[0035] In one embodiment of this embodiment, please refer to Figure 1 The supporting assembly 40 includes a pressing block 41, an elastic member 42 and a support block 43. The pressing block 41 is connected to the press roller shaft 30, the support block 43 is arranged on the mounting seat 10, and the elastic member 42 is arranged between the pressing block 41 and the support block 43 and is in a compressed state. Specifically, the pressing block 41 in this embodiment is fixed to the mounting seat 10 by screws. In other embodiments, the pressing block 41 can also be integrally formed with the mounting seat 10, and the pressing block 41 is a part of the structure of the mounting seat 10. By arranging the elastic member 42 between the pressing block 41 and the support block 43, and the elastic member 42 is in a compressed state, it is possible to apply an elastic force to the press roller shaft 30.

[0036] In one embodiment of this embodiment, please refer to Figure 1 The pressing block 41 and the supporting block 43 are arranged opposite each other. One end of the elastic member 42 is connected to the pressing block 41, and the other end of the elastic member 42 is connected to the supporting block 43. Specifically, in this embodiment, the elastic member 42 is configured as a spring. By arranging the pressing block 41 opposite the supporting block 43, the transmission of elastic force is facilitated.

[0037] In one embodiment of this embodiment, please refer to Figure 1 The abutting assembly 40 includes a limiting rod 44, which is inserted through the pressure block 41 and the support block 43, and an elastic member 42 is sleeved on the limiting rod 44. Specifically, the limiting rod 44 passes through the support block 43 from the side of the support block 43 facing away from the pressure block 41 and is fixedly connected to the pressure block 41. The elastic member 42 is a spring, which is sleeved on the limiting rod 44, and the two ends of the spring are respectively in abutment with the support block 43 and the pressure block 41. By providing the limiting rod 44, it is easy to install the elastic member 42, the structure is simple, and it is conducive to reducing costs.

[0038] In some embodiments, the limiting rod 44 is threadedly connected to the support block 43 or the pressure block 41, and one end of the elastic member 42 abuts the pressure block 41, while the other end of the elastic member 42 abuts the limiting rod 44. In this arrangement, the degree of compression of the elastic member 42 can be changed by rotating the limiting rod 44, thereby adjusting the elastic force to adapt to the different requirements of different die-cut materials for different degrees of compaction.

[0039] In one embodiment of this embodiment, please refer to Figure 1 The mounting base 10 is provided with a chute 101, and the pressing block 41 is slidably engaged with the chute 101. By providing the chute 101 on the mounting base 10 and the pressing block 41 slidably engaging with the chute 101, the pressing block 41 can drive the pressing roller shaft 30 to move along the chute 101 away from the feeding roller shaft 20, so as to facilitate loading and unloading of the die-cutting material.

[0040] Specifically, a handle 70 is provided at the end of the press roller shaft 30 , and the handle 70 is used for a worker to apply external force so that the pressing block 41 drives the press roller shaft 30 to move along the chute 101 away from the feed roller shaft 20 .

[0041] In one embodiment of this embodiment, please refer to Figures 1 to 3 , Figure 2 yes Figure 1 A schematic cross-sectional structural diagram of the roller shaft body 31; Figure 3 yes Figure 1 Schematic diagram of the front view structure of the mounting rod 32. The pressing roller 30 includes a roller body 31 and a mounting rod 32. The roller body 31 is provided with a rotation hole 301, and the mounting rod 32 is passed through the rotation hole 301. Both ends of the mounting rod 32 are connected to the mounting seat 10, and the supporting assembly 40 is connected to at least one end of the mounting rod 32, and the roller body 31 is opposite to the feeding roller 20. Specifically, the mounting rod 32 is clamped between the pressure block 41 and the mounting seat 10. The mounting rod 32 is clearance-matched with the rotation hole 301 to achieve relative rotation. In this embodiment, corresponding supporting assemblies 40 are provided at both ends of the mounting rod 32 to facilitate uniform distribution of the elastic supporting force of the pressing roller 30 on the die-cutting material. By arranging the roller body 31 and the mounting rod 32, the roller body 31 and the mounting seat 10 can be installed so that they can rotate relative to each other.

[0042] In one embodiment of this embodiment, please refer to Figure 1The feeding device 100 includes a feed roller 50, which is arranged on the mounting seat 10 and is used to wind the die-cutting material. The feed roller 50 is provided with a limiting structure 51, which is used to limit the axial displacement of the die-cutting material along the feed roller 50. Specifically, the feed roller 50 can rotate relative to the mounting seat 10, and the feed roller 50 is parallel to the feed roller shaft 20 and the pressure roller shaft 30. The limiting structure 51 is a plurality of limiting rings, and the die-cutting material is wound around the position between two adjacent limiting rings on the feed roller 50, so as to limit the axial movement of the die-cutting material along the feed roller 50 through the limiting rings, thereby ensuring the reliability of the die-cutting process.

[0043] In one embodiment of this embodiment, there are multiple feed rollers 50, and the multiple feed rollers 50 are arranged around the feed roller shaft 20 and the nip roller shaft 30. Specifically, in this embodiment, the number of feed rollers 50 is four. In other embodiments, the number of feed rollers 50 can also be other numbers, and the present invention does not specifically limit the number of feed rollers 50. By providing multiple feed rollers 50, and multiple feed rollers 50 being arranged around the feed roller shaft 20 and the nip roller shaft 30, the stability of conveying the die-cut material is improved.

[0044] In one embodiment of this embodiment, please refer to Figure 1 The feed mechanism 100 includes a magnetic powder brake 60 connected to the feed roller 20. The magnetic powder brake 60 is used to adjust the braking torque applied to the feed roller 20 during rotation relative to the mounting base 10. It is understood that workers can use the magnetic powder brake 60 to adjust the braking torque applied to the feed roller 20 during rotation, further compacting the die-cut material and further reducing the asynchronous jump in the x-axis. Because different die-cut materials require different degrees of compaction, the magnetic powder brake 60 can be used to adapt the braking torque to meet the compaction requirements of different die-cut materials.

[0045] See also Figure 1 The present invention also provides a die-cutting device comprising a feeder 100 and a die-cutting device (not shown). The feeder 100 is used to transport die-cutting material to the die-cutting device for die-cutting. By incorporating the feeder 100 provided in the present invention into the die-cutting device, the die-cutting material is kept in the desired compact state, reducing the x-axis asynchronous jump distance during processing, improving the utilization rate of the die-cutting material, and thus reducing costs.
