Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting equipment manufacturing and die-cutting forming processing, in particular to a same-die multi-stage asynchronous die-cutting device. Background Art

[0002] The conventional die-cutting process currently involves laminating a substrate and a main material, or a release film, to the main material. This is then followed by die-cutting or multiple small hole-forming punching. Excess material is removed, leaving the desired product area, which is then the finished product. This current die-cutting process results in large gaps between the die-cut products and low material utilization. This has led to the rapid development of asynchronous cutting machines.

[0003] Existing asynchronous methods in the market, whether single, dual, or even multiple asynchronous methods, are limited to one-segment asynchronous operation in the X-direction and do not include multi-segment asynchronous operation in the Y-direction. If the asynchronous materials are not aligned, separate molds must be opened for asynchronous operation. The corresponding equipment also requires additional stations for mounting molds and composite materials, increasing the number of molds and equipment stations required, and increasing processing costs. Summary of the Invention

[0004] The present invention provides a same-mode multi-segment asynchronous die-cutting method, which can solve one or more of the above-mentioned problems in the prior art.

[0005] According to one aspect of the present invention, there is provided a same-mold multi-segment asynchronous die-cutting machine, comprising a frame, on which a first channel and a cutting mechanism are arranged, wherein the material to be cut passes through the first channel and is cut into discontinuous material by the cutting mechanism; the first channel is capable of conveying multiple strips of material at the same time; the cutting mechanism comprises a knife roller; the knife roller is rotatably mounted on the frame, and the knife roller is provided with a plurality of knife heads along the axial direction.

[0006] The material can be conveyed along the first channel in the X-direction, with multiple strips of material arranged along the first channel in the Y-direction. The cutting mechanism's blade roller is axially equipped with multiple cutting heads for cutting the material. These heads are also arranged above the first channel in the Y-direction. The cutting mechanism can simultaneously cut multiple strips of material conveyed along the first channel, achieving asynchronous cutting in the Y-direction. The multiple axially distributed blade heads on the cutting mechanism's blade roller can be dispersed along the roller's axial surface. As the blade roller rotates, they can contact the material at different times, each cutting the material at a different location, achieving asynchronous cutting in the X-direction. This enables multiple uses of the same mold, improves material utilization, reduces mold opening costs, and increases machine utilization, reducing costs and enhancing competitiveness in the industry. When the blade heads come into contact with the material, they cut the material, producing discontinuous material.

[0007] In some embodiments, the frame is equipped with a conveyor mechanism capable of intermittent material feeding. Thus, the conveyor mechanism can transport the material to be cut from one end of the device to the cutting mechanism, and the resulting cut product can be conveyed to the other end of the device. This intermittent feeding mechanism facilitates control over the point at which the cutting head contacts the material. By adjusting the operating and resting times of the conveyor mechanism and coordinating the position of the cutting head on the cutter roller, the length of the material cut along the X-axis can be adjusted as needed.

[0008] In some embodiments, the conveying mechanism includes a first rotating roller and a first pressing roller in a transmission connection. The first rotating roller and the first pressing roller are mounted side by side on a frame for rotation, with a first passage formed between the first rotating roller and the first pressing roller. The first rotating roller is connected to a first motor, which is capable of driving the first rotating roller to rotate intermittently. The first pressing roller and the first rotating roller can be connected to each other via a gear, chain, or conveyor belt, and the first rotating roller is connected to the rotating shaft of the first motor. As a result, the first rotating roller rotates with the operation of the first motor and drives the first pressing roller to rotate, allowing the material to be cut to pass between the first rotating roller and the first pressing roller. The squeezing action between the first rotating roller and the first pressing roller prevents the material from falling during conveyance. The first motor drives the first rotating roller to rotate intermittently, thereby intermittently conveying the material, facilitating adjustment of the length of the material cut along the X-axis by the cutting mechanism.

[0009] In some embodiments, a second rotating roller is provided below the cutter roller. The second rotating roller and the cutter roller are mounted on the frame for rotational alignment. The second rotating roller and the cutter roller are connected by a transmission mechanism, and the material to be cut passes between the two rollers. The cutter roller is connected to a second motor, which can drive the cutter roller to rotate continuously. The second rotating roller and the cutter roller can be connected by a transmission mechanism such as gears, a chain, or a conveyor belt. Thus, the material to be cut travels along the first channel to the cutting mechanism under the action of a conveyor mechanism. The material passes between the cutter roller and the second rotating roller, and the material, squeezed by the cutter roller and the second rotating roller, comes into contact with a cutter head mounted on the cutter roller. The cutter roller rotates continuously under the drive of the second motor. When the cutter head rotates with the cutter roller until it contacts the material, it cuts the material, thereby producing discontinuous material.

[0010] In some embodiments, the cutter head is elongated, with a triangular cross-section, and the tip of the cutter head pointing outward from the cutter roller. This ensures that the sharp, pointed blade contacts the material as it cuts, resulting in a smooth, burr-free cut surface. The material is conveyed along the X-direction, with the axial direction of the cutter roller aligned with the Y-direction. If the long side of the cutter head is positioned along the axial direction of the cutter roller, the material can be cut along the Y-direction. When the long side of the cutter head forms a certain angle with the axial direction of the cutter roller, the cutting surface also forms a certain angle with the Y-direction. Furthermore, depending on the width of the material, cutter heads of different lengths can be used for cutting.

[0011] In some embodiments, the blade roller can be divided into multiple cutting die zones along the axial direction, and the multiple strips of material conveyed by the first channel correspond to the cutting die zones one by one. Thus, each strip of material conveyed on the first channel can contact and be cut by the blade, thereby rationally utilizing space and power resources and improving machine utilization.

[0012] In some embodiments, each of the multiple cutting die areas is configured with at least one cutting head. The number of cutting heads in each cutting die area can be selected based on the size of the desired product, the rotation speed of the cutting roller, the material conveying speed, and the interval time, thereby improving machine utilization. When the desired spacing material product is longer in size, the cutting die area corresponding to the material can be configured with fewer cutting heads, so that the material is cut less frequently during one rotation of the cutting roller. When the desired spacing material product is shorter in size, the cutting die area corresponding to the material can be configured with more cutting heads, so that the material is cut less frequently during one rotation of the cutting roller.

[0013] In some embodiments, the cutting heads within the same die zone can be arranged evenly or unevenly around the cutting roller. Thus, when the cutting heads within the same die zone are evenly arranged, the material cut in that die zone can produce discontinuous products of uniform size. When the cutting heads within the same die zone are unevenly arranged, the material cut in that die zone can produce discontinuous products of inconsistent size. This can meet various cutting requirements and enhance the practicality of the equipment.

[0014] In some embodiments, the frame of the same-die multi-stage asynchronous die-cutting device further includes a second channel for conveying materials, the second channel being located below the first channel. The second channel aligns with the first channel in conveying direction, thereby enabling other materials to be conveyed below the first channel, such as a backing film to receive the resulting product material after cutting.

[0015] In some embodiments, the transmission mechanism further includes a second pressure roller and a spacing roller; the second pressure roller is disposed between the first rotating roller and the first pressure roller; the second pressure roller is in transmission connection with the first rotating roller, and a second channel is formed between the first rotating roller and the second pressure roller; the spacing roller is disposed between the first pressure roller and the second pressure roller, and both the first pressure roller and the second pressure roller are in transmission connection with the spacing roller; and a first channel is formed between the first pressure roller and the spacing roller. The second pressure roller and the first rotating roller can be in transmission connection with each other via gears, chains, or conveyor belts, and the first and second pressure rollers can be in transmission connection with the spacing roller via gears, chains, or conveyor belts. Thus, both the second channel and the first channel can transmit materials under the action of the first rotating roller, thereby simultaneously transmitting the main material and auxiliary materials, thereby facilitating cutting, saving space, improving the utilization of power resources, and reducing cost investment.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figures 1 to 3 A schematic diagram illustrates a multi-stage asynchronous die-cutting device for the same die according to one embodiment of the present invention. As shown, the device comprises a frame 10, on which a first channel 20 and a second channel 30 are provided along the X-direction. Multiple strips of main material to be cut can be conveyed through the first channel 20, with the strips distributed along the Y-direction on the first channel 20. A base film can be conveyed through the second channel 30. The frame 10 is also provided with a conveying mechanism 40 and a cutting mechanism 50. The conveying mechanism 40 drives the material along the X-direction, and the cutting mechanism 50 cuts the material into discontinuous strips.

[0022] A conveyor mechanism 40 is mounted on the frame 10. The conveyor mechanism 40 includes a first rotating roller 41, a first pressure roller 42, a second pressure roller 43, and a spacing roller 44, which are connected in a transmission manner. The first rotating roller 41 and the first pressure roller 42 are mounted side by side on the frame 10. The first rotating roller 41 is connected to a first motor, which drives the first rotating roller 41 to rotate intermittently. A second pressure roller 43 is positioned between the first rotating roller 41 and the first pressure roller 42, and a spacing roller 44 is positioned between the first pressure roller 42 and the second pressure roller 43. The first pressure roller 42, spacing roller 44, second pressure roller 43, and first rotating roller 41 are arranged one above the other on the frame 10. The first pressure roller 42, spacing roller 44, second pressure roller 43, and first rotating roller 41 are connected by intermeshing gears. A first passage 20 is defined between the first pressure roller 42 and the spacing roller 44, while a second passage 30 is defined between the second pressure roller 43 and the first rotating roller 41.

[0023] The first channel 20 can simultaneously convey multiple strips of material. Figure 1As shown, four main materials are conveyed simultaneously in the first channel 20, and a wider auxiliary material support film is conveyed in the second channel 30. Driven by the conveying mechanism 40, the main materials and the support film to be cut are respectively conveyed along the first channel 20 and the third channel 30 to the cutting mechanism 50.

[0024] The cutting mechanism 50 includes a blade roller 51, with a second rotating roller 52 positioned below the blade roller 51. The blade roller 51 and the second rotating roller 52 are connected via a gear transmission. The blade roller 51 is connected to a second motor and is driven by the second motor for continuous rotation. Both the multiple main materials in the first channel 20 and the auxiliary materials in the second channel 30 can pass between the blade roller 51 and the second rotating roller 52. As the main materials and auxiliary materials pass through, the cutting mechanism 50 only cuts the main materials.

[0025] like Figure 4 As shown, four cutting die areas 511 are provided on the cutting roller 51 along the axial direction, and each cutting die area 511 is provided with a plurality of cutting heads 512. The four cutting die areas 511 can correspond one to one to the four materials conveyed by the first channel 20. The cutting head 512 is long and the long side of the cutting head 512 is arranged along the axial direction of the cutting roller 51. The cross-section of the cutting head 512 is triangular, and the tip of the cutting head 512 points from the cutting roller 51 to the outside of the cutting roller 51. The multiple cutting heads 512 in each cutting die area 511 are unevenly arranged around the cutting roller 51. As the cutting roller 51 rotates, the cutting head 512 can cut the main material when it contacts the main material, and separate the material into discontinuous materials.

[0026] The blades 512 of each die zone 511 are unevenly distributed around the cutter roller 51, enabling asynchronous cutting of the same strip of material in the X-direction. The size of the resulting product can be adjusted by controlling the rotational speed of the cutter roller 511, the distance between adjacent blades 512 in the corresponding die zone 511, and the material conveying speed and dwell time. Multiple die zones 511 on the cutter roller 51 cut multiple strips of material arranged in the Y-direction, achieving asynchronous Y-direction cutting. This allows for multiple uses of the same die, improving the equipment's practicality and applicability.

[0027] Along the first and second channels 20 and 30, downstream of the cutting mechanism 50, a laminating mechanism can be provided for laminating the resulting products. The laminating mechanism includes a third pressure roller 62 and a third rotating roller 61. The third pressure roller 62 and the third rotating roller 61 are meshed with each other via gears, and both the first and second channels 20 and 30 pass between the third pressure roller 62 and the third rotating roller 61. The second channel 30 can be used to convey the base film. The discontinuous material obtained by separating the material in the first channel 20 through the cutting mechanism 50 and the base film can be laminated through the extrusion between the third pressure roller 62 and the third rotating roller 61.

[0028] The device has a compact structure and strong practicality, can reasonably utilize power resources, improve the utilization rate of the machine, reduce the mold opening cost, and can be adjusted according to cutting requirements, and has a wide range of applications.

[0029] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all fall within the scope of protection of the present invention.
