[0024] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a suspended asynchronous die-cutting device 100 according to an embodiment of an implementation mode of the present invention; Figure 2 yes Figure 1A schematic diagram of the three-dimensional structure of the cutting die 31, the upper die 33 and the limit block 32 of the die-cutting die 30 in the suspended asynchronous die-cutting device 100. The embodiment of the present invention provides a suspended asynchronous die-cutting device 100, which includes a first feeding device 10, a second feeding device 20 and a die-cutting die 30. The first feeding device 10 is used to convey the material belt 200, and the second feeding device 20 is used to convey the main material 300. The feeding speed of the second feeding device 20 is lower than the feeding speed of the first feeding device 10. The die-cutting die 30 includes a cutting die 31, a limiting block 32, an upper die 33 and a lower die 34. The upper die 33 and the lower die 34 are arranged opposite to each other. The lower die 34 is used to carry the material strip 200. The cutting die 31 and the limiting block 32 are both arranged on the upper die 33. The limiting block 32 is provided with a limiting groove 321. The limiting groove 321 is used to accommodate the main material 300 and limit the swinging of the main material 300 along the width direction. In the length direction of the main material 300, the cutting die 31 is opposite to the limiting block 32. The cutting die 31 is used to cut the main material 300.

[0025] Specifically, the conveying directions of the first feeding device 10 and the second feeding device 20 are the same, and are parallel to the length direction of the material strip 200 and the length direction of the main material 300. The upper die 33 is located on the top side of the lower die 34, and the knife die 31 and the limit block 32 are arranged on the bottom side of the upper die 33. The knife die 31 is provided with a knife head (not shown) for cutting the main material 300. The suspended asynchronous die-cutting device 100 also includes a driving mechanism (not shown), which can drive the upper die 33 and the lower die 34 to close the mold. During the closing process, the knife die 31 cuts off the product part on the main material 300, and makes the product part compound with the material strip 200 on the lower die 34. The waste part left after the main material 300 is cut continues to be driven by the second feeding device 20 for recycling.

[0026] In some embodiments, in the width direction, the main material 300 abuts against the inner wall of the limiting groove 321, and the main material 300 cannot swing along the width direction, so that the main material 300 can always be aligned with the cutting head of the cutting die 31, and the main material 300 can be cut accurately, reducing the risk of material shortage.

[0027] In other embodiments, in the width direction, the main material 300 and the inner wall of the limiting groove 321 are relative to each other at a small distance, and the main material 300 can only swing slightly along the width direction, which has little impact on the die-cutting of the main material 300. The main material 300 can still be cut accurately, reducing the risk of material shortage and cutting.

[0028] By setting a limit block 32 on the upper mold 33, the limit block 32 has a limit groove 321. The limit groove 321 can accommodate the main material 300 and limit the swing of the main material 300 along the width direction, thereby reducing the swing of the main material 300 in the upper mold 33. The main material 300 can be accurately cut by the cutting die 31, reducing the risk of material shortage and cutting, and improving the stability of the die-cutting process. In addition, the width of the main material 300 does not need to be set too large, thereby improving the utilization rate of the main material 300.

[0029] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The second feeding device 20 includes a feeding roller 21 and a waste collecting roller 22. In the length direction, the feeding roller 21 and the waste collecting roller 22 are respectively arranged on both sides of the limiting groove 321, and the distance between the feeding roller 21 and the die-cutting mold 30 is equal to the distance between the waste collecting roller 22 and the die-cutting mold 30. The feeding roller is used to feed the main material 300 to the die-cutting mold 30, and the waste collecting roller 22 is used to roll away the main material 300 that has been die-cut. It should be noted that the distance between the feeding roller 21 and the die-cutting mold 30 refers to the distance from the feeding roller 21 to the die-cutting mold 30, and the distance between the waste collecting roller 22 and the die-cutting mold 30 refers to the distance from the die-cutting mold 30 to the waste collecting roller 22. In this arrangement, the die-cutting die 30 is located in the middle of the feeding roller 21 and the scrap collecting roller 22, and the limit block 32 can better limit the swing of the main material 300, which is beneficial to improve the accuracy of die-cutting and reduce the risk of material shortage and cutting.

[0030] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The number of the limit blocks 32 is multiple, and the knife die 31 is arranged between two adjacent limit blocks 32. Such an arrangement can better limit the swing of the main material 300, so that the knife die 31 can accurately cut the main material 300.

[0031] In this embodiment, there are two limit blocks 32, and the two limit blocks 32 are respectively arranged at the front side and the rear side of the cutting die 31. In other embodiments, the number of the limit blocks 32 may also be greater than or equal to three.

[0032] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , Figure 3 yes Figure 2 A schematic cross-sectional view of a cutting die 31, an upper die 33 and a limiting block 32; Figure 4 yes Figure 2Schematic diagram of the structure of the limiting block 32. The limiting groove 321 includes a top wall 3211 and a first side wall 3212 and a second side wall 3213 opposite to each other. The top wall 3211 connects the first side wall 3212 and the second side wall 3213. The first side wall 3212 is provided with a relatively protruding first boss 322, and / or the second side wall 3213 is provided with a relatively protruding second boss 323. In this way, the main material 300 can be limited from leaving the limiting groove 321 along the thickness direction.

[0033] In this embodiment, the first side wall 3212 is provided with a first boss 322, and the second side wall 3213 is provided with a second boss 323, and the first boss 322 and the second boss 323 can abut against the bottom surface of the main material 300 to limit the main material 300 from leaving the limiting groove 321. In other embodiments, only the first side wall 3212 may be provided with the first boss 322, or only the second side wall 3213 may be provided with the second boss 323.

[0034] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 In the width direction, the first boss 322 and the second boss 323 are spaced apart from each other. In this way, the gap between the first boss 322 and the second boss 323 can be inserted into the main material 300, so that the main material 300 can be placed in the limiting groove 321, which improves the convenience of processing.

[0035] In one embodiment of this implementation, please refer to Figure 5 , Figure 5 It is a schematic diagram of the structure of the limit block 32 under another embodiment of the embodiment of the present invention. In the width direction, the first boss 322 can slide relative to the first side wall 3212 to get close to or away from the top wall 3211; and / or, the second boss 323 can slide relative to the second side wall 3213 to get close to or away from the top wall 3211. With such a configuration, the size of the limit groove 321 in the thickness direction can be adjusted so that the size of the limit groove 321 is adapted to the main material 300, which will neither subject the main material 300 to a large friction force, causing the main material 300 to wear, nor provide too much space for the main material 300 to slip or flip, thereby reducing the risk of material shortage and cutting, and improving the reliability of the die-cutting process.

[0036] In this embodiment, the first boss 322 and the second boss 323 can slide relative to the first side wall 3212 and the second side wall 3213, respectively, to approach or move away from the top wall 3211. In other embodiments, one of the first boss 322 and the second boss 323 can be configured to slide relative to the corresponding side wall, and the other can be configured to be fixed relative to the corresponding side wall.

[0037] Specifically, the first boss 322 can slide on the first side wall 3212 by means of a slider and a slide groove. For example, the first boss 322 is provided with a slider, and the first side wall 3212 is provided with a slide groove. The slider and the slide groove slide together so that the first boss 322 can slide along the first side wall 3212 to approach or move away from the top wall 3211. In this way, a worker can push the first boss 322 to slide the first boss 322 along the first side wall 3212 to a suitable position so that the size of the limiting groove 321 is adapted to the main material 300. The way the second boss 323 slides on the second side wall 3213 can refer to the first boss 322 and the first side wall 3212, or it can be different from them.

[0038] In one embodiment of this implementation, please refer to Figure 6 , Figure 6 3 is a schematic diagram of the structure of a limit block 32 under another embodiment of the present invention. The limit block 32 includes a first limit portion 3202, a connecting portion 3201, and a second limit portion 3203 which are sequentially connected and enclosed to form a limit groove 321, the connecting portion 3201 is connected to the upper mold 33, the surface of the first limit portion 3202 facing the second limit portion 3203 is a first side wall 3212, the surface of the second limit portion 3203 facing the first limit portion 3202 is a second side wall 3213, and the first limit portion 3202 and / or the second limit portion 3203 can slide relative to the connecting portion 3201 to adjust the distance between the first side wall 3212 and the second side wall 3213. With such a configuration, the width dimension of the limiting groove 321 can be adjusted so that the first side wall 3212 and the second side wall 3213 can abut against the two sides of the limiting groove 321 in the width direction or have a suitable distance, ensuring that the main material 300 will not be subjected to a large friction force, causing the main material 300 to be worn, and will not cause the main material 300 to slip or flip, thereby reducing the risk of material shortage and cutting, and improving the reliability of the die-cutting process.

[0039] In this embodiment, the first limiting portion 3202 and the second limiting portion 3203 can slide relative to the connecting portion 3201, that is, the first limiting portion 3202 and the second limiting portion 3203 can move closer to or farther from each other to adjust the width of the limiting groove 321. In addition, the first limiting portion 3202 and the second limiting portion 3203 can slide relative to the connecting portion 3201 in the same direction to adjust the relative position of the limiting groove 321 in the upper mold 33 to meet different processing requirements. For example, when processing different products, it is necessary to cut different positions of the main material 300, and the worker can adjust the relative position of the limiting groove 321 in the upper mold 33 through the first limiting portion 3202 and the second limiting portion 3203, so that the designated area of ​​the main material 300 can be aligned with the cutting die 31.

[0040] In one embodiment of this implementation, please refer to Figure 7 , Figure 7 3 is a schematic diagram of the structure of a limiting block 32 in another embodiment of the present invention. There are multiple limiting grooves 321, and multiple limiting grooves 321 are arranged along the width direction. In this way, multiple main materials 300 can be limited at the same time, thereby improving the processing efficiency and reliability.

[0041] In one embodiment of this implementation, please refer to Figure 3 The limit block 32 is provided with a connection hole 324, the upper die 33 is provided with a fixing hole 331, and the die-cutting die 30 includes a fastener (not shown), one end of the fastener abuts against the limit block 32, and the other end of the fastener passes through the connection hole 324 and matches with the fixing hole 331. In this way, the limit block 32 and the upper die 33 can be detachably connected, so that different limit blocks 32 can be replaced according to different processing requirements.

[0042] In this embodiment, the connecting hole 324 is a stepped through hole, the fixing hole 331 is a threaded hole, and the locking piece is a screw. The locking piece can pass through the connecting hole 324 and be threadedly connected to the fixing hole 331, and the head of the locking piece abuts against the stepped bottom surface of the stepped through hole, so that the limit block 32 and the upper mold 33 are relatively fixed.

[0043] In one embodiment of this implementation, please refer to Figure 8 , Figure 8 3D schematic diagram of the three-dimensional structure of the cutting die 31, the upper die 33 and the limit block 32 in another embodiment of the present invention. The connecting hole 324 is a strip hole extending along the width direction. In this way, the relative position of the limit block 32 and the upper die 33 can be adjusted through the strip hole to meet different processing requirements.

[0044] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
