Description

Technical Field

[0001] The present invention relates to the technical field of paper cutting equipment, and more specifically, to a paper feeding and cutting machine. Background Art

[0002] With the development of technology, the level of industrial automation has been continuously improved, and new types of paper cutting machines have gradually replaced traditional manual cutting methods. Paper cutting machines can cut various papers such as process paper, packaging cartons, book covers, and self-adhesive labels, and have higher quality and processing efficiency than manual cutting.

[0003] The existing paper cutting machine completes cutting by a cutter head installed on the machine head passing over the paper. The cutter head is eccentrically installed on the tool holder, and the cutter head can rotate freely relative to the tool holder. The paper processed by it will leave redundant cutting lines at the starting position of the cutting line. Specifically, at the beginning of cutting, the electrical equipment controls the movement of the machine head. After moving to the cutting position, the machine head descends to make the cutter head contact the paper. However, at this time, the rotation angle of the cutter head stays at the angle at the end of the previous cut, and the angle is uncontrollable. When the cutter head contacts the paper, there will be a rotational resistance. When the machine head moves, the cutter head will automatically rotate to a suitable angle to complete the cutting. However, during the process from the initial contact of the cutter head with the paper to rotating to a suitable angle, the cutter head will cut the paper and leave redundant marks, and generally a small arc cutting line will be left at the front end of the cutting line. That is, the cutting line of the existing paper cutting machine has defects and cannot cut the integrity of the graphic. Summary of the Invention

[0004] The problem solved by the present invention is that no redundant cutting lines should appear during the cutting operation of the paper feeding and cutting machine, and the integrity of the cutting graphic should be ensured.

[0051] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings.

[0052] In the description of the present invention, it should be noted that the terms indicating directions such as "upper", "lower", "front", "rear", etc. in each embodiment are only used to simplify the description of the positional relationship based on the drawings of the specification, and do not represent that the indicated elements and devices must operate according to the specific directions, limited operations, methods, and structures described in the specification. Such terms indicating directions do not constitute a limitation to the present invention.

[0053] In addition, the terms "first" and "second" mentioned in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0054] Combined with Figures 1 to 19 As shown, the embodiments of the present invention provide a paper - feeding cutting machine, which is used to cut papers such as packaging paper boxes, book covers, and self - adhesive labels, can automatically complete the cutting work according to user needs, and can improve the paper - cutting accuracy and production efficiency.

[0055] Combined with Figure 1 and Figure 2As shown in the figure, the paper feeding and cutting machine includes a frame 1, in which control components of the paper feeding and cutting machine are installed. On the frame 1, there are a paper placing platform 2, a cutting table 3, a material receiving hopper 4 and a cross beam 5. The paper placing platform 2 is used for placing the paper to be cut. The paper cutting work is completed on the cutting table 3. The material receiving hopper 4 is used for collecting the cut paper. The cross beam 5 can move back and forth. A machine head 6 is arranged on the cross beam 5, and a cutting component is arranged on the machine head 6. The machine head 6 can move left and right along the cross beam 5 for cutting operations. This paper feeding and cutting machine is highly automated and can automatically complete the whole set of processes of paper feeding, cutting and material receiving according to the settings, without manual operation.

[0056] Combined with Figures 1 to 3 As shown in the figure, three feeding baffles 24 are arranged on the paper placing platform 2, which are respectively used to limit the positions of the left side, right side and rear side of the paper. The bottom of the feeding baffle 24 is magnetically connected to the paper placing platform 2. The magnetic connection method enables the feeding baffle 24 to move arbitrarily on the paper placing platform 2, adjust the limiting position according to the paper size, which is convenient to operate and has good practical value. In other embodiments, the number of the feeding baffles 24 can be adjusted according to needs, and the limiting effect is better when the number of the feeding baffles 24 is increased. A platform lifting mechanism 23 is arranged at the bottom of the paper placing platform 2, which is used to drive the paper placing platform 2 to move up and down and adjust the height of the paper placing platform 2. The platform lifting mechanism 23 automatically lifts and lowers according to the placing height of the paper to ensure that the paper on the paper placing platform 2 can be sent to the cutting table 3.

[0057] The cutting table 3 includes rollers arranged on the front and rear sides and a conveyor belt sleeved on the rollers. When one of the rollers rotates, it drives the conveyor belt to move, and the other roller rotates accordingly. After the paper is cut on the cutting table 3, the conveyor belt moves to transfer the paper to the material receiving hopper 4. In the prior art, the cutting table 3 is welded and fixed to the frame 1. The assembly method of the conveyor belt is to wrap the whole piece of felt or rubber around the rollers on both sides, and then bond the two ends of the felt or rubber together. The bonding operation needs to be completed on the frame 1, which is inconvenient to operate and has a poor bonding effect. The joint of the conveyor belt is uneven and easy to come off. In this embodiment, the whole cutting table 3 is erected on the frame 1, and it is fixedly connected to the frame 1 by screws and can be removed as a whole. In this way, the conveyor belt can complete the bonding operation on an external processing platform, and then directly sleeve the annular conveyor belt on the rollers, making the joint of the conveyor belt smoother, with good connection effect and extended service life of the conveyor belt. Moreover, the cutting table 3 and the frame 1 can be detachably connected, which is convenient for part inspection and replacement.

[0058] The paper on the cutting table 3 is conveyed to the receiving hopper 4 through a conveyor belt. The upper surface of the receiving hopper 4 is inclined downward towards the discharging direction, facilitating the sliding of the paper in the receiving hopper 4. An independent receiving rack can be arranged on the front side of the receiving hopper 4 to collect the paper sliding out of the receiving hopper 4. Two discharging baffles 41 are provided on the receiving hopper 4 to limit the discharging position of the paper. The bottom of the discharging baffle 41 is magnetically connected to the receiving hopper 4, and the discharging baffle 41 can move freely on the receiving hopper 4. The placement position of the discharging baffle 41 is adjusted according to the discharging position of the paper to ensure the limiting effect. In this embodiment, the discharging baffles 41 are arranged on the left and right sides of the receiving hopper 4, and the rear part of the discharging baffle 41 has an inclined guiding surface. The guiding surfaces of the two discharging baffles 41 on both sides have opposite inclined directions, forming a guiding structure with a gradually decreasing opening. This structure is beneficial for the receiving hopper 4 to collect the paper entering from different positions.

[0059] Linear guide rails 51 are provided on the left and right sides of the frame 1. The two sides of the cross beam 5 are connected to the linear guide rails 51, and the cross beam 5 can move back and forth along the linear guide rails 51. A head moving mechanism is arranged inside the cross beam 5 to drive the cutting head 6 to move left and right on the cross beam 5. Through the movement of the cross beam 5 and the cutting head 6, the cutting component can move to any position on the cutting table 3 to meet various cutting requirements.

[0060] Combined Figures 3 to 8 As shown, the paper feeding and cutting machine of this embodiment has a paper feeding structure, which can convey the paper placed on the paper placing platform 2 to the cutting table 3, and it is necessary to ensure that only one piece of paper placed on the top is conveyed each time to avoid waste of paper caused by multiple pieces of paper entering the cutting table 3 simultaneously. An adsorption device is provided at the bottom of the cross beam 5. The adsorption device includes a plurality of suction cups. During paper feeding, the cross beam 5 moves along the linear guide rail 51 to the upper part of the paper placing platform 2. The suction cups contact the top paper and pump air to suck it. Then the cross beam 5 moves along the linear guide rail 51 to the upper part of the cutting table 3, and the suction cups release air, and the paper falls onto the conveyor belt for subsequent cutting operations. Combined Figure 3 As shown, a plurality of ventilation holes 21 are provided on the paper placing platform 2. The ventilation holes 21 are arranged at the front part of the paper placing platform 2, corresponding to the position where the adsorption device sucks the paper. The ventilation holes 21 can prevent the paper placed at the bottom from sticking to the paper placing platform 2 and ensure that the paper at the bottom can be sucked up. A paper placing sensor 22 is also provided on the paper placing platform 2 to confirm whether there is still paper on the paper placing platform 2, so that the user can find out in time when the paper is used up.

[0061] However, the stacked papers are likely to stick to each other, especially when sucking air-permeable paper, the adsorption device is likely to suck multiple pieces of paper at one time. To solve the above problems, the paper feeding and cutting machine of this embodiment has a blowing plate 8 and a paper pressing mechanism. The blowing plate 8 is arranged between the paper placing platform 2 and the cutting table 3. Combined Figure 4 and Figure 5As shown, a plurality of air-distributing grooves 82 are provided on the air-blowing plate 8, and air-blowing holes 81 are provided in the air-distributing grooves 82. The air-blowing holes 81 are vertical linear holes, and the air outflow velocity is high. When the adsorption device sucks the paper, the air-blowing holes 81 blow air towards the paper placing platform 2, and the blown air is rectified in the air-distributing grooves 82 and then blows towards the paper, which can create gaps between adjacent papers and separate them from each other. The air-blowing plate 8 is integrally formed, which can ensure that the air-distributing grooves 82 and the air-blowing holes 81 on the air-blowing plate 8 have the same setting height, so that the air outlet heights of the air-blowing holes 81 in the left-right direction are consistent, improving the paper separation effect.

[0062] Combined with Figures 6 to 8 As shown, a paper pressing member 70 and a paper pressing driving mechanism are provided on the cross beam 5. The paper pressing driving mechanism is connected to the paper pressing member 70 and is used to drive the paper pressing member 70 to press or release the paper. When the cross beam 5 moves to the paper sucking position, the paper pressing driving mechanism drives the paper pressing member 70 to move downwards to press the front part of the paper. The air-blowing plate 8 blows air to blow open the paper at the top. The suction cup at the bottom of the cross beam 5 sucks the uppermost separated paper. The paper pressing driving mechanism drives the paper pressing member 70 to move upwards to release the paper, and the cross beam 5 moves to transfer the paper to the cutting table 3.

[0063] In this embodiment, the paper pressing driving mechanism is a paper pressing cylinder 74. In other embodiments, the paper pressing driving mechanism can also be other driving mechanisms such as a motor. The paper pressing member 70 includes a paper pressing rotating shaft 71, two side extension rods 73 and a paper pressing rod 72. The paper pressing rotating shaft 71 is fixed on the cross beam 5. The paper pressing cylinder 74 is connected to the paper pressing rotating shaft 71. The extension rods 73 extend from both sides of the paper pressing rotating shaft 71 towards the paper placing platform 2. The paper pressing rod 72 is connected to the extension ends of the extension rods 73. The extension length of the extension rods 73 determines the part of the paper pressed by the paper pressing rod 72. When the paper pressing rod 72 presses the middle front part of the paper, the paper separation effect is good. When the paper pressing mechanism works, the paper pressing cylinder 74 pushes the paper pressing rotating shaft 71 to rotate, drives the extension rods 73 to rotate downwards, and makes the paper pressing rod 72 press the paper. When the paper pressing mechanism releases, the paper pressing cylinder 74 retracts, the paper pressing rotating shaft 71 rotates in the reverse direction and drives the extension rods 73 to rotate upwards, and makes the paper pressing rod 72 move upwards to release the paper.

[0064] Preferably, the paper pressing cylinder 74 is connected to the paper pressing rotating shaft 71 through a paper pressing spring 75. When the paper pressing cylinder 74 pushes the paper pressing rotating shaft 71 to rotate, the paper pressing spring 75 will be stretched. After the cylinder retracts, the deformation of the paper pressing spring 75 is restored, so that the paper pressing rotating shaft 71 and the paper pressing rod 72 return. The setting of the paper pressing spring 75 enables the pressure generated by the paper pressing member 70 to have an adjustment space, which can improve the paper separation effect and is beneficial for the paper pressing member 70 to return to the initial position.

[0065] Combined with Figures 9 to 19As shown, the machine head 6 includes a connecting plate 601, a fixing plate 602, a tool rest 603, a cutting component, a machine head lifting mechanism, and a machine head rotating mechanism. The connecting plate 601 is assembled with the cross beam 5 and can move on the cross beam 5. The fixing plate 602 is fixedly connected to the connecting plate 601. A tool rest guide rod 605 is provided on the fixing plate 602. The tool rest 603 is connected to the tool rest guide rod 605 and can move up and down along the tool rest guide rod 605. The cutting component is installed on the tool rest 603. Specifically, the cutting component includes a plurality of tool head assemblies. A tool seat 604 is provided on the tool rest 603, and the tool head assemblies are installed on the corresponding tool seats 604. The machine head lifting mechanism is connected to the tool rest 603 and is used to drive the tool rest 603 to move up and down. The machine head rotating mechanism is connected to the tool head assemblies and is used to drive each tool head assembly to rotate. Each tool head assembly controls the rotation angle through the machine head rotating mechanism, and the rotation angle of each tool head assembly is controllable. When the machine head 6 cuts, the tool head assembly that needs to perform the cutting work is moved to an appropriate height through the machine head lifting mechanism, the tool head assembly is controlled to rotate through the machine head rotating mechanism, and the angle of the tool head assembly is adjusted at any time according to the set cutting line. The cutting line cut by this machine head 6 has no defects and completely coincides with the set cutting line, ensuring the integrity of the cutting pattern.

[0066] A positioning mechanism is provided on the tool rest 603 for determining the cutting position and ensuring the cutting accuracy. The positioning mechanism includes a positioning camera 671 and a lighting lamp 672. The positioning camera 671 can position the cutting part of the paper so that the cutting component cuts according to the set walking path; the lighting lamp 672 provides illumination and is inclinedly installed on the tool rest 603 to prevent reflection.

[0067] Combined with Figure 9 As shown, the machine head lifting mechanism includes a lifting motor 611, a lead screw 612, and a lifting nut 613. The motor shaft of the lifting motor 611 is connected to the lead screw 612. The lifting nut 613 is assembled on the lead screw 612, and the lifting nut 613 is fixedly connected to the tool rest 603. When the lifting motor 611 works, it drives the lead screw 612 to rotate. The lifting nut 613 will move up and down along the lead screw 612. When the lifting nut 613 moves, the tool rest 603 moves up and down along the tool rest guide rod 605. The machine head lifting mechanism can control the movement of the tool rest 603 and adjust the height of the tool rest 603, that is, it can control the height of the tool head assembly so that the cutting part of the tool head assembly contacts the paper on the cutting table 3.

[0068] Combined with Figure 12As shown in the figure, in this embodiment, the cutting component includes three cutter head assemblies, namely a full-cut cutter head assembly 63, a half-cut cutter head assembly 64, and a pressure wheel cutter head assembly 65. Among them, the full-cut cutter head assembly 63 can cut the paper completely through, mainly used for paper splitting and cutting hollow patterns; the half-cut cutter head 644 will not cut the paper through, but will leave a deeper cut mark on the paper surface, which can be used for cutting self-adhesive labels, etc.; the pressure wheel cutter head assembly 65 is used to press a crease on the paper to facilitate paper folding, and is often used for cutting the paper of packaging boxes. The head rotation mechanism includes a rotation motor 621, a synchronous belt 622, and synchronous gears. The number of synchronous gears is the same as the number of cutter head assemblies. The cutter head assembly has a rotating sleeve, and the rotating sleeve is installed in the tool holder 604 and can rotate relative to the tool holder 604. Each synchronous gear is respectively connected to a rotating sleeve to control the rotation of the corresponding cutter head assembly.

[0069] In this embodiment, the number of synchronous gears is three, namely the first synchronous gear 623, the second synchronous gear 624, and the third synchronous gear 625. The full-cut cutter head assembly 63 includes a first rotating sleeve 632, the half-cut cutter head assembly 64 includes a second rotating sleeve 642, and the pressure wheel cutter head assembly 65 includes a third rotating sleeve 651. The first synchronous gear 623 is connected to the first rotating sleeve 632 and moves synchronously. The second synchronous gear 624 is connected to the second rotating sleeve 642 and moves synchronously. The third synchronous gear 625 is connected to the third rotating sleeve 651 and moves synchronously. The synchronous belt 622 surrounds the three synchronous gears and plays a transmission role among the three synchronous gears. The pressure wheel cutter head assembly 65 includes a connecting shaft 657. The motor shaft of the rotation motor 621 is fixedly connected to the connecting shaft 657. When the rotation motor 621 works, the pressure wheel cutter head assembly 65 rotates accordingly. The rotation of the third synchronous gear 625 causes the synchronous belt 622 to move, thereby driving the first synchronous gear 623 and the second synchronous gear 624 to rotate. The full-cut cutter head assembly 63 and the half-cut cutter head assembly 64 will also rotate accordingly. Therefore, in this embodiment, the third synchronous gear 625 is the driving wheel, and the first synchronous gear 623 and the second synchronous gear 624 are the driven wheels. In other embodiments, the motor shaft of the rotation motor 621 can be connected to any one of the cutter head assemblies. The cutter head assembly directly connected to the rotation motor 621 rotates, and then drives other cutter head assemblies to rotate, so that the rotation angles of multiple cutter head assemblies can be controlled by one rotation motor 621 to meet the needs of cutting operations.

[0070] Combined with Figure 14 and Figure 15As shown, the full-cut cutter head assembly 63 includes a first rotating sleeve 632, a first cutter sleeve, a full-cut cutter head 634, and a full-cut cutter handle 635. The first cutter sleeve is fixedly installed inside the first rotating sleeve 632. The full-cut cutter head 634 is installed on the full-cut cutter handle 635. A clamping groove is provided on the full-cut cutter handle 635, and a first sealing ring 638 is clamped in the clamping groove. The full-cut cutter handle 635 is inserted into the first cutter sleeve, and the first sealing ring 638 is clamped with the assembly groove of the first cutter sleeve, so that the full-cut cutter handle 635 is fixed in the first cutter sleeve. The connection between the full-cut cutter handle 635 and the first cutter sleeve is reliable and convenient to disassemble. A first positioning groove 636 is provided at the tail of the full-cut cutter handle 635, and a first positioning pin 637 is arranged in the positioning groove. Both ends of the first positioning pin 637 are fixed on the first cutter sleeve, so that the full-cut cutter handle 635 cannot rotate freely. The rotation angle of the full-cut cutter head 634 is controlled by the head rotation mechanism. The tip of the full-cut cutter head 634 is located on the rotation axis of the full-cut cutter head assembly 63, reducing the rotational resistance during cutting of the full-cut cutter head 634 and avoiding cutter head damage.

[0071] Combined with Figure 16 and Figure 17 As shown, the half-cut cutter head assembly 64 includes a second rotating sleeve 642, a second cutter sleeve, a half-cut cutter head 644, a half-cut cutter handle 645, a cutter head end cover 649, and a cutter head spring 640. The second cutter sleeve is fixedly installed inside the second rotating sleeve 642. The half-cut cutter head 644 is installed on the half-cut cutter handle 645. A clamping groove is provided on the half-cut cutter handle 645, and a second sealing ring 648 is clamped in the clamping groove. The half-cut cutter handle 645 is inserted into the second cutter sleeve, and the second sealing ring 648 is clamped with the assembly groove of the second cutter sleeve, so that the half-cut cutter handle 645 is fixed in the second cutter sleeve. The connection between the half-cut cutter handle 645 and the second cutter sleeve is reliable and convenient to disassemble. The cutter head end cover 649 is sleeved on the front part of the half-cut cutter head 644 and is used to control the cutting depth of the half-cut cutter head 644. The cutting depth is the part exposed from the cutter head end cover 649. The cutter head spring 640 is sleeved outside the half-cut cutter handle 645 and abuts against the cutter head end cover 649 at one end, which can control the exposed length of the half-cut cutter head 644, that is, control the cutting depth and prevent cutting through. A second positioning groove 646 is provided at the tail of the half-cut cutter handle 645, and a second positioning pin 647 is arranged in the positioning groove. Both ends of the second positioning pin 647 are fixed on the second cutter sleeve, so that the half-cut cutter handle 645 cannot rotate freely. The rotation angle of the half-cut cutter head 644 is controlled by the head rotation mechanism. The tip of the half-cut cutter head 644 is located on the rotation axis of the half-cut cutter head assembly 64, reducing the rotational resistance during cutting of the half-cut cutter head 644 and avoiding cutter head damage.

[0072] Combined with Figure 18 and Figure 19As shown in the figure, the pressing wheel cutter head assembly 65 includes a third rotating sleeve 651, a pressing wheel cutter head 652, and a pressing wheel cutter handle 653. The pressing wheel cutter head 652 is installed on the pressing wheel cutter handle 653. A clamping groove is provided on the pressing wheel cutter handle 653, and a third sealing ring 656 is clamped in the clamping groove. The pressing wheel cutter handle 653 is inserted into the third rotating sleeve 651, and the third sealing ring 656 is clamped with the assembly groove of the third rotating sleeve 651, so that the pressing wheel cutter handle 653 is fixed in the third rotating sleeve 651. The connection between the pressing wheel cutter handle 653 and the third rotating sleeve 651 is reliable and convenient to disassemble. A third positioning groove 654 is provided at the tail of the pressing wheel cutter handle 653, and a third positioning pin 655 is arranged in the positioning groove. Both ends of the third positioning pin 655 are fixed on the third rotating sleeve 651, so that the pressing wheel cutter handle 653 cannot rotate freely, and the rotation angle of the pressing wheel cutter head 652 is controlled by the head rotation mechanism.

[0073] The cutter heads of the three cutter head assemblies cannot rotate freely, and the rotation angle of each cutter head can be controlled by the head rotation mechanism, so that cutting can be completed according to the setting. The cutting line has no defects, improving the cutting accuracy.

[0074] During the cutting operation of the paper feeding cutting machine, only one cutter head assembly works each time. Therefore, the cutter head assemblies need to be set at different heights to avoid multiple cutter heads cutting the paper simultaneously and damaging the paper. In this embodiment, the height of the pressing wheel cutter head assembly 65 is the lowest, and the full-cut cutter head assembly 63 and the half-cut cutter head assembly 64 are at higher positions. The full-cut cutter head assembly 63 has a first air cylinder 631 that can adjust the height of the full-cut cutter head 634, and the half-cut cutter head assembly 64 has a second air cylinder 641 that can adjust the height of the half-cut cutter head 644. When the pressing wheel cutter head assembly 65 needs to perform cutting, the first air cylinder 631 and the second air cylinder 641 are in the retracted state. The head lifting mechanism controls the lifting of the tool rest 603 so that the pressing wheel cutter head 652 contacts the paper. At this time, the full-cut cutter head 634 and the half-cut cutter head 644 do not contact the paper. The cross beam 5 and the head 6 move to control the cutting position, and the head rotation mechanism controls the rotation angle of the pressing wheel cutter head 652, that is, a scoring tangent line can be made on the paper according to the setting. When the full-cut cutter head 634 is needed for cutting, the first air cylinder 631 extends, so that the height of the full-cut cutter head 634 is lower than that of the pressing wheel and the half-cut cutter head 644. The head lifting mechanism adjusts the position of the tool rest 603, and the tip of the full-cut cutter head 634 contacts the paper. Cutting is completed by controlling the movement of the head 6 and the rotation of the full-cut cutter head 634. When the half-cut cutter head 644 is needed for cutting, the first air cylinder 631 retracts, and the second air cylinder 641 extends, so that the height of the half-cut cutter head 644 is lower than that of the pressing wheel and the full-cut cutter head 634. The head lifting mechanism adjusts the position of the tool rest 603, and the tip of the half-cut cutter head 644 contacts the paper. The cutting operation is completed by controlling the movement of the head 6 and the rotation of the half-cut cutter head 644.

[0075] Combined Figure 9 、 Figure 10 、 Figure 11 andFigure 13 As shown, a marking component 66 is further provided on the tool rest 603 for marking on the paper. The marking component 66 includes a pen holder 661, a pen holder guide rod 662, a marker pen 663 and a third cylinder 665. The pen holder 661 is connected to the pen holder guide rod 662 and can move up and down along the pen holder guide rod 662. The third cylinder 665 is connected to the pen holder 661. A pen clip 664 is provided on the pen holder 661, and the marker pen 663 is fixed to the pen holder 661 through the pen clip 664. When the machine head 6 performs cutting operations, the height of the marker pen 663 should be higher than that of the cutting component to prevent unnecessary marks from appearing on the paper. When marking is required, the third cylinder 665 extends to push the pen holder 661 downward, and the tip of the marker pen 663 is lower than the cutting head of the cutting component. The machine head lifting mechanism adjusts the position of the tool rest 603 so that the tip of the marker pen 663 contacts the paper, and when the machine head 6 moves, marks can be left on the paper.
