Description

Technical Field

[0001] The present invention relates to the technical field of paper cutting equipment, and more particularly, to a cutting machine head and a 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 is rotatable relative to the tool holder. For the paper processed by paper cutting, there will be redundant cutting lines at the starting position of the cutting line. The specific reason is that 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 when the previous cutting was completed, and the angle is uncontrollable. After the cutter head contacts the paper, a force will be generated. 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 the rotation to a suitable angle, the cutter head will cut the paper and leave redundant traces. Generally, a small arc cutting line will be left at the front end of the cutting line. That is, the cutting lines of the existing paper cutting machine have defects and cannot guarantee the integrity of the cutting pattern. 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 cutting machine head, and the integrity of the cutting pattern is guaranteed.

[0005] To solve the above problems, the present invention provides a cutting machine head, including a fixing plate, a tool holder, a cutting component, a machine head lifting mechanism, and a machine head rotating mechanism. The tool holder is installed on the fixing plate. The machine head lifting mechanism is connected to the tool holder and is used to drive the tool holder to move up and down on the fixing plate.

[0043] To make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0044] In the description of the present invention, it should be noted that the term nouns such as "upper", "lower", "front", "rear" indicating directions in each embodiment are only used to simplify the description of the positional relationship based on the accompanying drawings of the specification, and do not represent that the indicated elements and devices, etc. must operate according to the specific directions and limited operations, methods and structures in the specification. Such directional nouns do not constitute a limitation to the present invention.

[0045] 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.

[0046] Combined with Figures 1 to 13As shown in the figure, an embodiment of the present invention provides a paper feeding and cutting machine, which is used to cut papers such as packaging cartons, book covers, and self-adhesive labels. It can automatically complete the cutting work according to user needs, and can provide paper cutting accuracy and production efficiency.

[0047] Combined with Figure 1 and Figure 2 As shown, the paper feeding and cutting machine includes a frame 1. The control elements of the paper feeding and cutting machine are installed inside the frame 1. A paper placing platform 2, a cutting table 3, a material receiving hopper 4, and a cross beam 5 are provided on the frame 1. The paper placing platform 2 is used to place the papers to be cut. The paper cutting work is completed on the cutting table 3. The material receiving hopper 4 is used to collect the cut papers. The cross beam 5 can move back and forth. A machine head 6 is provided on the cross beam 5, and a cutting component is provided 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 full set of processes of paper feeding, cutting, and material receiving according to the settings, without manual operation.

[0048] Three feeding baffles 24 are provided 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, with convenient operation and good practical value. In other embodiments, the number of feeding baffles 24 can be adjusted according to needs, and the limiting effect is better when the number of feeding baffles 24 is increased. A platform lifting mechanism 23 is provided 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 placement height of the paper, ensuring that the papers on the paper placing platform 2 can be sent to the cutting table 3.

[0049] The cutting table 3 includes rollers provided 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 entire 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, with inconvenient operation and poor bonding effect. The joint of the conveyor belt is uneven and easy to come off. However, in this embodiment, the cutting table 3 is integrally mounted 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 onto 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.

[0050] 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 slopes downward towards the discharging direction, facilitating the sliding of the paper in the receiving hopper 4. An independent receiving rack can be provided 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 arbitrarily 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 inclined directions of the guiding surfaces of the two discharging baffles 41 on both sides are opposite, forming a guiding structure with a gradually decreasing opening. This structure is conducive to the receiving hopper 4 collecting the paper entering from different positions.

[0051] Linear guide rails 51 are provided on the left and right sides of the frame 1, and both sides of the cross beam 5 are connected to the linear guide rails 51. 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 head 6 to move left and right on the cross beam 5. Through the movement of the cross beam 5 and the head 6, the cutting component can move to any position on the cutting table 3 to meet various cutting requirements.

[0052] Combined Figures 3 to 13 As shown, the head 6 includes a connecting plate 601, a fixing plate 602, a tool holder 603, a cutting component, a head lifting mechanism, and a 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 holder guide rod 605 is provided on the fixing plate 602. The tool holder 603 is connected to the tool holder guide rod 605 and can move up and down along the tool holder guide rod 605. The cutting component is installed on the tool holder 603. Specifically, the cutting component includes a plurality of tool head assemblies. A tool seat 604 is provided on the tool holder 603, and the tool head assemblies are installed on the corresponding tool seats 604. The head lifting mechanism is connected to the tool holder 603 to drive the tool holder 603 to move up and down. The head rotating mechanism is connected to the tool head assemblies to drive each tool head assembly to rotate. The rotation angles of the respective tool head assemblies are controlled by the head rotating mechanism, and the rotation angle of each tool head assembly is controllable. When the head 6 cuts, the tool head assembly that needs to perform the cutting work is moved to a suitable height through the head lifting mechanism, and the tool head assembly is controlled to rotate through the head rotating mechanism. The angle of the tool head assembly is adjusted at any time according to the set cutting line. The cutting line cut by this head 6 has no flaws and completely coincides with the set cutting line, ensuring the integrity of the cutting pattern.

[0053] The tool rest 603 is provided with a positioning mechanism 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 locate the cutting part of the paper, enabling the cutting component to perform cutting according to the set walking path; the lighting lamp 672 provides illumination and is inclinedly installed on the tool rest 603 to prevent reflection.

[0054] Combined with Figure 3 As shown, the 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 is fixedly connected to the tool rest 603. When the lifting motor 611 operates, it drives the lead screw 612 to rotate, and 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 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 cutter head assembly, so that the cutting part of the cutter head assembly contacts the paper on the cutting table 3.

[0055] Combined with Figure 6 As shown, in this embodiment, the cutting component includes three cutter head assemblies, namely a full-cut cutter head assembly 63, a semi-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 and is mainly used for paper splitting and cutting hollow patterns; the semi-cut cutter head 644 does not cut the paper through but leaves a deeper cut mark on the paper surface and 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 commonly used for cutting paper for 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.

[0056] 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 tool head assembly 63 includes a first rotating sleeve 632, the half-cut tool head assembly 64 includes a second rotating sleeve 642, and the pressing wheel tool 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 timing belt 622 slews the three synchronous gears and plays a role in transmission between the three synchronous gears. The pressing wheel tool head assembly 65 includes a connecting shaft 657. The motor shaft of the rotating motor 621 is fixedly connected to the connecting shaft 657. When the rotating motor 621 works, the pressing wheel tool head assembly 65 rotates accordingly. The rotation of the third synchronous gear 625 causes the timing belt 622 to move, thereby driving the first synchronous gear 623 and the second synchronous gear 624 to rotate. The full-cut tool head assembly 63 and the half-cut tool 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 rotating motor 621 can be connected to any one of the tool head assemblies. The tool head assembly directly connected to the rotating motor 621 rotates, and then drives the other tool head assemblies to rotate, so that the rotation angles of multiple tool head assemblies can be controlled by one rotating motor 621 to meet the needs of cutting operations.

[0057] Combined with Figure 8 and Figure 9 As shown, the full-cut tool head assembly 63 includes a first rotating sleeve 632, a first tool sleeve, a full-cut tool head 634, and a full-cut tool handle 635. The first tool sleeve is fixedly installed in the first rotating sleeve 632. The full-cut tool head 634 is installed on the full-cut tool handle 635. A clamping groove is provided on the full-cut tool handle 635, and a first sealing ring 638 is clamped in the clamping groove. The full-cut tool handle 635 is inserted into the first tool sleeve, and the first sealing ring 638 is clamped with the assembly groove of the first tool sleeve, so that the full-cut tool handle 635 is fixed in the first tool sleeve. The connection between the full-cut tool handle 635 and the first tool sleeve is reliable and easy to disassemble. A first positioning groove 636 is provided at the tail of the full-cut tool 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 tool sleeve, so that the full-cut tool handle 635 will not rotate freely. The rotation angle of the full-cut tool head 634 is controlled by the head rotation mechanism. The tip of the full-cut tool head 634 is located on the rotation axis of the full-cut tool head assembly 63, reducing the rotation resistance suffered by the full-cut tool head 634 during cutting and avoiding tool head damage.

[0058] Combined with Figure 10 and Figure 11As shown, the half-cut tool head assembly 64 includes a second rotating sleeve 642, a second tool sleeve, a half-cut tool head 644, a half-cut tool handle 645, a tool head end cap 649, and a tool head spring 640. The second tool sleeve is fixedly installed inside the second rotating sleeve 642. The half-cut tool head 644 is installed on the half-cut tool handle 645. A clamping groove is provided on the half-cut tool handle 645, and a second sealing ring 648 is clamped in the clamping groove. The half-cut tool handle 645 is inserted into the second tool sleeve, and the second sealing ring 648 is clamped with the assembly groove of the second tool sleeve, so that the half-cut tool handle 645 is fixed in the second tool sleeve. The connection between the half-cut tool handle 645 and the second tool sleeve is reliable and convenient to disassemble. The tool head end cap 649 is sleeved on the front part of the half-cut tool head 644 and is used to control the cutting depth of the half-cut tool head 644. The cutting depth is the part that exposes the tool head end cap 649. The tool head spring 640 is sleeved outside the half-cut tool handle 645, and one end abuts against the tool head end cap 649, which can control the exposed length of the half-cut tool 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 tool 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 tool sleeve, so that the half-cut tool handle 645 will not rotate freely. The rotation angle of the half-cut tool head 644 is controlled by the head rotation mechanism. The tip of the half-cut tool head 644 is located on the rotation axis of the half-cut tool head assembly 64, reducing the rotation resistance suffered by the half-cut tool head 644 during cutting and avoiding tool head damage.

[0059] Combined with Figure 12 and Figure 13 As shown, the press wheel tool head assembly 65 includes a third rotating sleeve 651, a press wheel tool head 652, and a press wheel tool handle 653. The press wheel tool head 652 is installed on the press wheel tool handle 653. A clamping groove is provided on the press wheel tool handle 653, and a third sealing ring 656 is clamped in the clamping groove. The press wheel tool 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 press wheel tool handle 653 is fixed in the third rotating sleeve 651. The connection between the press wheel tool 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 press wheel tool 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 press wheel tool handle 653 will not rotate freely. The rotation angle of the press wheel tool head 652 is controlled by the head rotation mechanism.

[0060] The tool heads of the three tool head assemblies will not rotate freely, and the rotation angle of each tool 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, and the cutting accuracy is improved.

[0061] During the cutting operation of the paper feeding and cutting machine, only one cutter head assembly works at a time. Therefore, it is necessary to set each cutter head assembly at a different height to avoid multiple cutter heads cutting 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 a higher position. 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 is required 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, the indentation tangent can be made on the paper according to the setting. When cutting with the full-cut cutter head 634, the first air cylinder 631 extends to make the height of the full-cut cutter head 634 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. The cutting is completed by controlling the movement of the head 6 and the rotation of the full-cut cutter head 634. When cutting with the half-cut cutter head 644, the first air cylinder 631 retracts and the second air cylinder 641 extends to make the height of the half-cut cutter head 644 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.

[0062] Combined with Figure 3 , Figure 4 , Figure 5 and Figure 7 as shown, a marking assembly 66 is further provided on the tool rest 603 for marking on the paper. The marking assembly 66 includes a pen holder 661, a pen holder guide rod 662, a marking pen 663 and a third air 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 air cylinder 665 is connected to the pen holder 661. A pen clip 664 is provided on the pen holder 661, and the marking pen 663 is fixed to the pen holder 661 through the pen clip 664. When the head 6 performs a cutting operation, the height of the marking pen 663 should be higher than that of the cutting assembly to prevent unnecessary marks from appearing on the paper. When marking is required, the third air cylinder 665 extends to push the pen holder 661 downward, and the tip of the marking pen 663 is lower than the cutter head of the cutting assembly. The head lifting mechanism adjusts the position of the tool rest 603 so that the tip of the marking pen 663 contacts the paper. When the head 6 moves, marks can be left on the paper.

[0063] An embodiment of the present invention provides a highly automated paper feeding and cutting machine. By means of a novel cutting machine head, it is ensured that the actual cutting line is consistent with the setting, and the cut paper is complete and flawless, achieving high-precision and high-efficiency paper cutting operations. Therefore, it has good industrial promotion value.

[0064] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
