[0107] The gap between the anvil roller 6 and the cutter roller 8 is adjusted through the gap adjusting device 2.

[0108] The waste separation roller 3 can rotate at the same speed as the cutter roller 8 through the transmission mechanism 9, or the waste separation roller 3 can be driven to rotate at the same speed as the cutter roller 8 by the friction force between the outer surface of the waste separation roller 3 and the outer surface of the cutter roller 8 when the cutter roller 8 and the waste separation roller 3 rotate, which is within the protection scope of the embodiments.

[0109] In this way, the outer surface of the waste separation roller 3 is covered with the elastic material 31, and when the waste separation roller 3 is in contact with the outer circular surface of the cutter roller 8 under the action of the separation roller pressing mechanism 4, a certain extrusion force is generated, the elastic material 31 is extruded into the blade, which is beneficial to completely separate the waste in the hole after cutting; the transmission mechanism 9 ensures that the rotational linear speed of the cutter roller 8 and the waste separation roller 3 is the same; and the gap adjusting device 2 facilitates adjustment of the gap between the anvil roller 6 and the cutter roller 8.

[0110] The embodiments also provide a flexible material high-speed online hole cutting device for performing the flexible material high-speed online hole cutting process according to any one of the above embodiments, which comprises the cutter roller 8, the waste separation roller 3, the anvil roller 6, the adsorption transfer mechanism 7, and the waste collection mechanism 5.

[0111] The outer circle of the cutter roller 8 is provided with a ring-shaped closed blade 81, the ring-shaped closed blade 81 is provided with a through hole 82, and the through hole 82 is in communication with the adsorption transfer mechanism 7.

[0112] Anvil roller 6 is located on one side of cutter roller 8, and the outer surface of anvil roller 6 is in contact with the outer surface of cutter roller 8. Waste separation roller 3 is located behind the contact surface between anvil roller 6 and cutter roller 8 in the production direction, and waste separation roller 3 is located on one side of cutter roller 8, and the outer surface of waste separation roller 3 is in contact with the outer surface of cutter roller 8.

[0113] The waste collection mechanism 5 is located behind the contact surface between the waste separation roller 3 and the cutter roller 8 in the production direction.

[0114] In this embodiment, the high-speed online hole cutting device for flexible materials includes a mold frame 1, a cutting roller 8, an anvil roller 6, an adsorption and transfer mechanism 7, a waste separation roller 3, a separation roller pressurization mechanism 4, a gap adjustment device 2, and a waste collection mechanism 5.

[0115] The outer surface of the cutting roller 8 is provided with annular closed cutting edges 81 for cutting the required hole shape. The cutting edge angle and depth on the cutting roller are selected according to the properties of the material being cut. The cutting edge angle is usually smaller on the inside and larger on the outside. Figure 4 As shown, this design avoids the waste material from being squeezed in and becoming difficult to remove, while also ensuring the strength of the blade.

[0116] Each annular closed blade 81 has one or more through holes 82 arranged radially along the roller body inside, and the through holes 82 are interconnected with the gas channels 83 arranged axially along the roller body of the cutter roller 8.

[0117] In other embodiments, the gas channel 83 may not be provided inside the cutter roller 8. As long as the adsorption and transfer mechanism 7 can provide negative or positive pressure gas to the through hole 82, it is within the protection scope of this embodiment.

[0118] The cutting roller 8 and the anvil roller 6 are rotatably mounted on the mold frame 1 in the vertical direction (as indicated by arrow b in the figure), and the cutting roller 8 and the waste separation roller 3 are rotatably mounted on the mold frame 1 in the horizontal direction (as indicated by arrow a in the figure).

[0119] The outer surface of the waste separation roller 3 is covered with an elastic material 31. A separation roller pressing mechanism 4 and a 1:1 transmission mechanism 9 are provided between the cutter roller 8 and the waste separation roller 3 (to ensure that the cutting roller and the waste separation roller rotate at the same linear speed). Under the action of the separation roller pressing mechanism 4, when the waste separation roller 3 contacts the outer surface of the cutter roller 3, a certain squeezing force will be generated, and the elastic material 31 will be squeezed into the blade, which is conducive to the complete separation of waste in the cut hole.

[0120] The separating roller pressurizing mechanism 4 adopts cylinder pressurization, oil cylinder pressurization and screw pressurization; the gap adjustment device 2 adopts a mechanism for adjusting the center distance between the cutter roller 8 and the anvil roller 6, such as shims, screw pressurization and cylinder pressurization.

[0121] like Figure 8As shown, the waste collection mechanism 5 includes a collection port 51 and a collection channel 52. The collection port 51 is located below the cutter roller 8, and the collection channel 52 is connected to the collection port 51.

[0122] In this embodiment, the cutting roller 8 is provided with an annular closed blade 81, and the annular closed blade 81 is provided with a through hole 82, which is connected to the adsorption and transfer mechanism 7; the waste separation roller 3 is located behind the contact surface between the anvil roller 6 and the cutting roller 8 in the production direction, and the waste collection mechanism 5 is located behind the contact surface between the waste separation roller 3 and the cutting roller 8 in the production direction.

[0123] Thus, the cutter roller 8 and the anvil roller 6 come into contact with each other and rotate relative to each other under a certain working pressure. The annular closed blade set on the cutter roller 8 can cut small holes in flexible materials 14, improving the aesthetics of the materials and improving product quality. The waste separation roller 3 squeezes the waste on the cutter roller 8, and the combination of the adsorption transfer mechanism 7 and the waste collection mechanism 5 can effectively transfer and collect the waste after punching, improving production efficiency.

[0124] According to some embodiments of this application, optionally, the adsorption transfer mechanism 7 includes an air suction area 71 and an air blowing area 72. The air suction area 71 extends from the contact surface between the anvil roller 6 and the cutter roller 8, the contact surface between the waste separation roller 3 and the cutter roller 8, to the area near the waste collection mechanism 5. The air blowing area 72 is disposed relative to the waste collection mechanism 5.

[0125] The adsorption and transfer mechanism 7 is set on both sides of the cutter roller 8. The gas distribution groove and gas distribution hole in the adsorption and transfer mechanism 7 are connected to the through hole 82 on the cutter roller 8. Negative pressure gas (so that the flexible material semi-finished product and waste are adsorbed on the outer surface of the cutter roller and rotated together with the cutter roller) or positive pressure gas (so that the waste is blown out from the inside of the cutter roller blade and falls into the waste collection mechanism 5) is delivered to the roller surface through the through hole 82.

[0126] like Figure 3 As shown, the adsorption transfer mechanism 7 is fixed on the bearing and is connected to the bearing of the cutter roller 8. The adsorption transfer mechanism 7 will not rotate, but the cutter roller 8 will rotate.

[0127] The positions of the blowing area 72 and the suction area 71 of the adsorption transfer mechanism 7 are determined during the design of the adsorption transfer mechanism 7. The adsorption transfer mechanism 7 is fixed and will not change due to the rotation of the cutter roller 8. The blowing area 72 is located near the waste collection mechanism 5.

[0128] Thus, the suction area 71 provides suction force for the cutter roller 8 to suck the flexible material 14, and the contact surface between the anvil roller 6 and the cutter roller 8, the contact surface between the waste separation roller 3 and the cutter roller 8, and the area close to the waste collecting mechanism 5 are all the suction area 71, which facilitates the transportation of the flexible material and the suction of the waste, and the area above the waste collecting mechanism 5 is the blowing area 72, which facilitates the blowing of the waste out of the cutter roller 8 and into the waste collecting mechanism 5.

[0129] According to some embodiments of the present application, the flexible material high-speed online hole cutting device further comprises a first material guide wheel 12 and a second material guide wheel 13, the first material guide wheel 12 is behind the waste separation roller 3 in the production direction, and the second material guide wheel 13 is behind the first material guide wheel 12 in the production direction.

[0130] Thus, the first material guide wheel 12 and the second material guide wheel 13 guide the flexible material semi-finished product.

[0131] According to some embodiments of the present application, the flexible material high-speed online hole cutting device further comprises a front auxiliary waste suction device 10 and a back auxiliary waste suction device 11, the front auxiliary waste suction device 10 and the back auxiliary waste suction device 11 are used to suck the waste attached to the flexible material semi-finished product, the front auxiliary waste suction device 10 and the back auxiliary waste suction device 11 are located between the first material guide wheel 12 and the second material guide wheel 13, the front auxiliary waste suction device 10 is located on the front of the flexible material semi-finished product, and the back auxiliary waste suction device 11 is located on the back of the flexible material semi-finished product.

[0132] Thus, the front auxiliary waste suction device 10 and the back auxiliary waste suction device 11 can prevent individual waste from being separated from the flexible material semi-finished product after passing through the waste separation roller and being attached to the flexible material semi-finished product and being brought into the next process to cause substandard waste.

[0133] According to some embodiments of the present application, the flexible material high-speed online hole cutting device further comprises a separation roller pressing mechanism 4, a transmission mechanism 9, and a gap adjusting device 2, the separation roller pressing mechanism 4 is connected with the waste separation roller 3, the separation roller pressing mechanism 4 is used to drive the waste separation roller 3 to approach or move away from the cutter roller 8 and apply working pressure, the waste separation roller 3 is in transmission connection with the cutter roller 8 through the transmission mechanism 9, and the gap adjusting device 2 is used to adjust the center distance between the cutter roller 8 and the anvil roller 6.

[0134] Thus, when the waste separation roller 3 contacts the outer circular surface of the cutter roller 8 under the action of the separation roller pressing mechanism 4, a certain extrusion force is generated, the elastic material 31 is extruded into the cutting edge, which is beneficial to the complete separation of the waste in the hole after cutting; the transmission mechanism 9 ensures that the rotational linear speed of the cutter roller 8 and the waste separation roller 3 is the same; and the gap adjusting device 2 facilitates the adjustment of the center distance between the cutter roller 8 and the anvil roller 6.

[0135] In use, the anvil roller 6, the cutter roller 8, the waste separation roller 3, the adsorption transfer mechanism 7, the gap adjusting device 2 and the waste collection mechanism 5 are installed on the die frame. The anvil roller 6 is brought into contact with the cutter roller 8 through the gap adjusting device 2, the cutter roller 8 is brought into contact with the waste separation roller 3 through the separation roller pressing mechanism 4, and a certain force is applied between them.

[0137] The hole cutter blade angle and the blade depth on the cutter roller 8 are selected according to the performance of the material to be cut. An adsorption through hole 82 is needed to be processed on the inner wall of each hole, and the adsorption gas passage 83 in the cutter roller 8 is penetrated. After the hole cutting device is installed, the distance between the cutter roller 8 and the waste separation roller 3 is adjusted according to the diameters of the cutter roller 8 and the waste separation roller 3, the fitting depth is set, and the grinding is carried out to make the cutter type of the waste separation roller 3 completely fit the cutter type of the cutter roller 8. The surface elastic material 31 of the waste separation roller 3 is embedded in the cutter type of the cutter roller 8 by 0.5mm to 2mm, and can extrude the waste in the flexible material on the cutter roller 8;

[0138] Then, the gap between the anvil roller 6 and the cutter roller 8 is adjusted through the gap adjusting device 2. The gap adjusting device 2 can adopt a gasket, a screw pressing, a cylinder pressing or other adjusting in-out mechanism. The material is put in for trial cutting, and the product and the waste are wrapped in the cutter roller 8;

[0139] The adsorption transfer mechanism 7 on both sides is used to transfer the waste to the waste collection mechanism 5.
