Technical Field
The invention relates to the technical field of die cutting equipment manufacturing and die cutting forming processing, in particular to a same-die multi-section asynchronous die cutting device.
Background
The conventional die cutting mode in the existing die cutting processing technology is that a substrate is attached to a main material, or a release film is attached to the main material, then die cutting or multiple small hole sleeve position die cutting is carried out through a cutting die, redundant waste materials are discharged, and a product area needing to be reserved is obtained, namely a processed finished product. In the existing die cutting processing technology, the typesetting clearance of die cutting products is large, and the utilization rate of main materials is low. And thus asynchronous cutting machines have been developed.
The existing market asynchronous mode is limited to one-segment asynchronization in the X direction no matter single asynchronization, double asynchronization or even more asynchronization, and does not relate to multiple-segment asynchronization in the Y direction. If the position of the asynchronous material is not on the same horizontal line, the mould needs to be opened separately and independently, the corresponding equipment also needs to be additionally provided with more stations for installing the mould and the composite material, the requirements on the number of the moulds and the stations of the equipment are increased, and the processing cost is high.

The invention provides a same-die multi-section asynchronous die cutting, which can solve one or more of the problems in the prior art.
According to one aspect of the invention, the same-die multi-section asynchronous die cutting device comprises a rack, wherein a first channel and a cutting mechanism are arranged on the rack, a material to be cut penetrates through the first channel, and the material to be cut is cut into discontinuous materials through the cutting mechanism; the first channel can convey a plurality of materials simultaneously; the cutting mechanism comprises a knife roll; the knife roll is rotatably arranged on the frame, and a plurality of knife heads are arranged along the axial direction of the knife roll.
The material can convey along the X direction along first passageway, and many materials are arranged along the Y direction at first passageway. Set up a plurality of tool bits that are used for cutting the material along the axial on cutting mechanism's the rotor, a plurality of tool bits are also arranged along the Y in the top of first passageway. Many materials that convey on the first passageway can be cut simultaneously through cutting the mechanism to realize that Y cuts to asynchronous. A plurality of tool bits that distribute along the axial on the rotor of cutting mechanism can disperse on the axial plane of rotor, when the rotor rotates, can not be in same time and material contact, and the position that each tool bit carries out the material and cuts is different, realizes that X is to asynchronous cutting. Therefore, the multi-purpose function of the same mold is realized, the utilization rate of materials is improved, the mold opening cost is reduced, the utilization rate of a machine table is improved, the cost is reduced, and the competitiveness of the same industry is improved. The material can be cut off when the cutter head is in contact with the material, so that the discontinuous material is obtained.
In some embodiments, the rack is provided with a conveying mechanism, and the conveying mechanism can feed materials intermittently. Therefore, the material to be cut can be conveyed to the cutting mechanism from one end of the equipment through the driving of the conveying mechanism, and the cut product is conveyed to the other end of the equipment. The intermittent feeding of the conveying mechanism can conveniently control the contact point between the cutter head on the cutting mechanism and the material, and the position of the cutter head on the cutter roller is matched through adjusting the running time and the stop time of the conveying mechanism in the conveying process, so that the length of the cutter head for cutting the material along the X direction can be adjusted as required.
In some embodiments, the conveying mechanism comprises a first rotating roller and a first pressing roller which are in transmission connection, the first rotating roller and the first pressing roller are rotatably mounted on the rack side by side, and a first channel is formed between the first rotating roller and the first pressing roller; the first rotating roller is connected with a first motor; the first motor can drive the first rotating roller to intermittently rotate. First compression roller and first rotation roller can be connected through mode transmission such as gear, chain or conveyer belt, and first rotation roller is connected with the pivot of first motor, and from this, first rotation roller can rotate and drive first compression roller along with the function of first motor and rotate to the material of treating to cut can pass between first rotation roller and the first compression roller, and, the material can be avoided droing at the data send process to the extrusion of first rotation roller and first compression roller. First motor drive first rotation roller intermittent type nature rotates to the conveying of material is also intermittent type nature, and the convenient adjustment cuts the mechanism and cuts the length of material along X to cutting.
In some embodiments, a second rotating roller is arranged below the knife roller, the second rotating roller and the knife roller are arranged on the rack in a side-by-side rotating mode, the second rotating roller is in transmission connection with the knife roller, and the material to be cut penetrates through the space between the knife roller and the second rotating roller; the knife roll is connected with a second motor, and the second motor can drive the knife roll to rotate continuously.

The knife roll rotates continuously under the drive of the second motor, and when the knife head rotates along with the knife roll to be in contact with the material, the knife head cuts the material, so that the discontinuous material is obtained.
In some embodiments, the cutting head is elongated, the transverse section of the cutting head is triangular, and the tip of the cutting head is directed to the outer side of the knife roll. Therefore, when the cutter head cuts materials, the sharp cutting edge of the cutter head is in contact with the materials, the cutting surface of the product is smooth, and the materials are burred. The material is conveyed along the X direction, and the axial direction of the knife roll is consistent with the Y direction; the long edge of the cutter head is arranged along the axial direction of the cutter roller, so that the material can be cut along the Y direction; when the long edge of the cutter head forms a certain included angle with the axial direction of the cutter roller, the cutting surface also forms a certain included angle with the Y direction. In addition, the cutter heads with different lengths can be selected for cutting according to different widths of materials.
In some embodiments, the knife roller can be divided into a plurality of knife die areas along the axial direction, and the plurality of materials conveyed by the first channel correspond to the knife die areas one by one. From this, each material of conveying on the first passageway can both contact with the tool bit to be cut by the tool bit, so can rational utilization space resource and power resource, improve the utilization ratio of board.
In some embodiments, the plurality of cutting dies are each configured with no less than one cutting head. The number of the tool bits can be selected according to the size of a required product, the rotating speed of the knife roll, the material conveying speed and the interval time in each cutting die area, and the utilization rate of the machine table is improved. When the size of the required spacing material product is long, the cutting die area corresponding to the material can be set to set a small number of tool bits, so that when the knife roller rotates for a circle, the number of times for cutting the material is small. When the size of the material product is shorter at required intervals, the cutting die area which can be used for setting the material to correspond is provided with a plurality of tool bits, so that when the knife roller rotates for a circle, the number of times for cutting the material is less.
