Description

Technical Field

[0001] This invention relates to the field of hot stamping and die-cutting machine technology, specifically to a longitudinal hot stamping and die-cutting machine. Background Technology

[0002] The main function of the paper conveying mechanism in a hot stamping and die-cutting machine is to accurately and stably transport the paper to be processed to the hot stamping / die-cutting station, directly affecting the hot stamping accuracy, die-cutting quality, and equipment production efficiency. To improve the automation level of paper conveying, Chinese invention patent document CN106629158B discloses a hot stamping and die-cutting machine, including an upper template, a lower template, and a paper conveying device. Its paper conveying device uses a robotic arm transfer mechanism in conjunction with a transmission mechanism to achieve paper conveying. Specifically, a power source drives a swing arm to swing left and right, which drives the input transmission wheel to rotate. After two stages of speed-increasing acceleration by a speed-increasing bridge wheel, it drives the output transmission wheel and sprocket chain to move. Suction cups on the chain adsorb the paper, conveying it from the bottom to the lower template worktable. During the process of the lower template flipping and fitting with the upper template, the main shaft drives a cam and a cable to pull a push gauge, completing the lateral positioning of the paper. However, in actual high-speed hot stamping and die-cutting production, this existing technology still suffers from insufficient conveying accuracy and poor hot stamping positioning stability. Firstly, the paper is not clamped and fixed during the hot stamping process, making it prone to displacement and resulting in decreased accuracy. In this solution, the suction cup only holds the paper during the conveying stage and releases it after it reaches the lower template worktable. Throughout the hot stamping process, the paper is in a clamp-free state, temporarily fixed only by the pressure and static friction when the upper and lower templates are attached. Under the combined effects of the impact force at the moment the templates close, the paper's rebound, and equipment vibration, the paper is highly susceptible to slight displacement or deflection, directly leading to hot stamping misregistration, die-cutting position deviation, and increased scrap rate. Especially under high-speed production conditions, the paper displacement problem is more prominent, directly affecting the accuracy of hot stamping or die-cutting.

[0003] Secondly, the existing conveying system requires multiple stages of transmission, including a motor, drive wheel, connecting rod, swing arm, input transmission wheel, speed-increasing bridge wheel, output transmission wheel, sprocket, and chain. The lengthy transmission chain results in high energy loss and low transmission efficiency. Furthermore, the meshing clearance of each gear accumulates progressively, further reducing transmission accuracy. At the same time, as a flexible transmission component, the chain has inherent elastic deformation and wear elongation issues. After long-term use, the chain pitch increases, and the conveying positioning accuracy gradually decreases. Moreover, the chain exhibits polygonal effects and vibrations during operation, resulting in poor conveying stability at high speeds, making it difficult to meet the positioning requirements of high-precision hot stamping and die-cutting. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a longitudinal hot stamping and die-cutting machine that addresses the shortcomings of the prior art, with a short transmission chain, good motion stability, high conveying accuracy, and the ability to continuously clamp the paper throughout the hot stamping process to prevent displacement and improve the hot stamping and die-cutting accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a longitudinal hot stamping and die-cutting machine, comprising a frame and a paper feeding device, a hot stamping and die-cutting device, a paper receiving device, and a clamping and conveying device disposed on the frame; the paper feeding device includes a liftable upper paper platform, a paper conveying platform disposed at the discharge end of the upper paper platform, and a paper suction feeder disposed above the upper paper platform for transferring paper from the upper paper platform to the paper conveying platform; the hot stamping and die-cutting device is disposed on the side of the paper conveying platform; the hot stamping and die-cutting device includes an execution module, a main drive cylinder for driving the execution module to reciprocate vertically, and a hot stamping and die-cutting worktable fixed on the frame and distributed below the execution module; a foil unwinding roller group and a foil winding roller group are respectively disposed on both sides of the execution module; characterized in that: the clamping and conveying device includes a feeding device extending from the paper feeding device to the paper receiving device. The system comprises a horizontally arranged guide rail mechanism, a main moving plate that slides along the horizontal guide rail mechanism, and an eccentric linkage drive mechanism that drives the main moving plate to reciprocate along the horizontal guide rail mechanism. Two clamping manipulators are mounted on the main moving plate, arranged sequentially along the horizontal guide rail mechanism. The eccentric linkage drive mechanism includes a floating drive arm and an eccentric wheel. The upper part of the floating drive arm is rotatably connected to the main moving plate. An upper linkage component slides along the middle part of the floating drive arm, and a lower linkage component slides along the lower part of the floating drive arm. The lower linkage component is rotatably positioned on the frame. The upper linkage component is eccentrically mounted on the eccentric wheel and rotatably connected to it. A servo motor that drives the eccentric wheel to rotate is linked to the middle part of the eccentric wheel, and the servo motor is fixed to the frame.

[0006] By adopting the above technical solution, the clamping robot installed on the main moving plate continuously clamps the paper during the conveying and hot stamping die-cutting process. The paper remains clamped and is not released when it is sent to the hot stamping die-cutting device for processing. This avoids the problem in the prior art where the paper shifts or deflects due to the impact force when the template closes, the paper rebounds, and the vibration of the equipment after the suction cup releases the paper. This effectively improves the hot stamping accuracy and die-cutting position accuracy and reduces the scrap rate. Furthermore, this solution directly drives the eccentric wheel with a servo motor, and through an eccentric linkage drive mechanism consisting of an upper linkage, a floating drive arm, and a lower linkage, directly converts the rotational motion into the horizontal reciprocating motion of the main moving plate. This shortens the transmission path and overcomes the problems of high energy loss, low transmission efficiency, and decreased transmission accuracy caused by the multi-stage transmission of "motor, drive wheel, linkage, swing arm, input transmission wheel, speed-increasing bridge wheel, output transmission wheel, sprocket, and chain" in existing technologies. At the same time, because this solution eliminates the chain as a flexible transmission component, it avoids the problem of increased pitch due to the inherent elastic deformation and wear elongation of the chain, which leads to a gradual decrease in conveying and positioning accuracy. It also avoids the polygonal effect and vibration of the chain during operation, thus maintaining stable conveying even at high speeds and meeting the positioning requirements of high-precision hot stamping and die-cutting.

[0007] Preferably, the horizontal guide rail mechanism includes two parallel second guide rails. Each clamping manipulator includes a clamping mounting base fixed to the main moving plate and a clamping cylinder fixed below the clamping mounting base. Several clamping springs are mounted above the clamping mounting base and arranged sequentially along the second guide rails. A fixed clamping piece is provided below each clamping spring. The fixed clamping piece is fixed to the clamping mounting base. One end of the clamping spring is fixedly connected to the clamping mounting base, and the other end of the clamping spring is connected to a connecting rod. A bent clamping hook is provided at this end. The output rod of the clamping cylinder is linked to a clamping lifting plate. The clamping lifting plate is simultaneously connected to several connecting rods. A strip-shaped clearance hole is opened on the fixed clamping piece corresponding to the connecting rod.

[0008] The above technical solution guides the main moving plate through two parallel second guide rails, ensuring the straightness and anti-deflection capability of the main moving plate and the clamping robot mounted on it during horizontal reciprocating movement. This prevents the main moving plate from deflecting during movement and provides a stable conveying guide foundation for the subsequent accurate clamping of paper by the clamping robot. Furthermore, a clamping cylinder drives the clamping lifting plate, which, through multiple connecting rods, simultaneously links the free ends of multiple clamping springs. This allows the clamping springs, arranged sequentially along the second guide rails, to be raised or lowered synchronously and uniformly. When the clamping hook is pressed down, the bent clamping hook hooks onto the edge of the paper and cooperates with the fixed clamping piece to form an elastic clamp, creating a hook-like anti-detachment constraint on the paper. This keeps the paper in a clamped state throughout the hot stamping and die-cutting process, effectively preventing the paper from slipping off the clamping end during high-speed conveying or mold closing impact, thereby avoiding paper displacement and improving hot stamping and die-cutting position accuracy. At the same time, the strip-shaped clearance hole on the fixed clamping piece corresponding to the connecting rod provides clearance space for the lifting and lowering action of the connecting rod, avoiding interference between the connecting rod and the fixed clamping piece, and ensuring smooth and reliable clamping action.

[0009] Preferably, the clamping mounting base includes an upper clamping fixing plate and a lower clamping fixing plate arranged on the side of the upper clamping fixing plate; the upper clamping fixing plate is fixed to the upper surface of the main moving plate by screws, and the clamping spring and the fixed clamping piece are both installed on the upper clamping fixing plate; a connecting block is connected to the middle of the lower clamping fixing plate, the connecting block is fixedly connected to the side of the main moving plate by screws, and a guide slider is installed on the side of the lower clamping fixing plate; a third guide slide rail is fixed on the frame and slides with the guide slider, the third guide slide rail being arranged parallel to the second guide slide rail; the clamping cylinder is installed in the middle of the lower clamping fixing plate, and guide sleeves are installed on both sides of the lower clamping fixing plate; each guide sleeve is slidably fitted with a guide rod, and the upper end of the guide rod is fixedly connected to the clamping lifting plate.

[0010] By adopting the above technical solution, the clamping mounting base is set as a separate structure of upper clamping fixing plate and lower clamping fixing plate. The clamping spring and fixed clamping plate for clamping paper are installed on the upper clamping fixing plate, and the clamping cylinder and lifting guide structure are installed on the lower clamping fixing plate, realizing the partitioned arrangement of clamping functional components and driving functional components. In addition, the guide slider on the side of the lower clamping fixing plate slides in cooperation with the third guide rail on the frame, which is parallel to the second guide rail. This allows the clamping robot to be guided and constrained by the second and third guide rails simultaneously during horizontal conveying. This enhances the straightness and lateral force resistance of the clamping mechanism in horizontal reciprocating motion, and prevents the clamping robot from deflecting or swaying due to uneven force during conveying, further ensuring the positioning accuracy of paper conveying. Furthermore, the lifting and lowering motion of the clamping lifting plate is guided by the sliding cooperation between the guide sleeves and guide rods on both sides of the lower clamping fixed plate, ensuring that the clamping lifting plate always rises and falls smoothly in the vertical direction without tilting under the drive of the clamping cylinder. This ensures that multiple connecting rods synchronously and evenly drive the free end of the clamping spring to lift or press down, so that the clamping hook of the clamping spring and the fixed clamping plate can achieve a smooth and accurate clamping and releasing action.

[0011] Preferably, the floating drive arm includes a floating drive plate and a first guide rail fixed to the floating drive plate by screws; the upper linkage component includes an upper linkage slider and a first rotating component fixedly connected to the upper linkage slider, the upper linkage slider slidingly engaging with the first guide rail, the eccentric wheel having a first linkage hole eccentrically provided on it, a first bearing being provided in the first linkage hole, and the end of the first rotating component away from the upper linkage slider being rotatably mounted at the first bearing; the lower linkage component includes a lower linkage slider and a second rotating component fixedly connected to the lower linkage slider, the lower linkage slider slidingly engaging with the first guide rail, a mounting plate fixedly provided below the eccentric wheel on the frame, a second linkage hole being provided on the mounting plate, a second bearing being provided in the second linkage hole, and the end of the second rotating component away from the lower linkage slider being rotatably mounted at the second bearing.

[0012] By adopting the above technical solution, by setting a first bearing in the first linkage hole of the eccentric wheel and a second bearing in the second linkage hole of the frame mounting plate, the rotational friction between the upper linkage component and the eccentric wheel, and between the lower linkage component and the frame, is converted into rolling friction. This significantly reduces the frictional resistance of each rotating pair during the eccentric wheel drive process, reduces energy loss, and improves transmission efficiency. At the same time, it avoids wear and heat generated by direct sliding friction, improves the durability and service life of each rotating pair, and ensures the smooth transmission of the eccentric wheel's rotational motion to the floating drive arm. Furthermore, by having both the upper and lower linkage sliders slide in cooperation with the same first guide rail, the upper and lower linkage components always maintain collinear motion trajectories and no relative deflection during the driving process of the floating drive arm. This ensures that the rotational motion of the eccentric wheel is stably converted into the oscillation of the floating drive arm, and avoids interference and jamming caused by asynchronous movement between the upper and lower linkage components. As a result, the horizontal reciprocating motion of the main moving plate driving the clamping robot along the horizontal guide rail mechanism is more stable and precise, further improving the conveying accuracy and hot stamping positioning stability of the hot stamping die-cutting machine.

[0013] Preferably, the first rotating member has a first positioning groove on its end face facing the upper linkage slider, and a plurality of first screw holes are provided in the first positioning groove. The upper linkage slider is inserted into the first positioning groove and is fastened to the first screw holes by screws. The second rotating member has a second positioning groove on its end face facing the lower linkage slider, and a plurality of second screw holes are provided in the second positioning groove. The lower linkage slider is inserted into the second positioning groove and is fastened to the second screw holes by screws.

[0014] By adopting the above technical solution, a first positioning groove is opened on the end face of the first rotating component and the upper linkage slider is inserted into the first positioning groove; a second positioning groove is opened on the end face of the second rotating component and the lower linkage slider is inserted into the second positioning groove. This allows for rapid and accurate initial positioning between the upper linkage slider and the first rotating component, and between the lower linkage slider and the second rotating component, during assembly. This ensures the alignment accuracy between the two components and avoids motion deviation caused by assembly eccentricity. Furthermore, a number of first and second screw holes in the positioning grooves are used to fasten the connection with screws, forming a firm and reliable fixed connection between the upper linkage slider and the first rotating component, and between the lower linkage slider and the second rotating component. This ensures that there is no loosening or relative displacement between the upper linkage slider and the first rotating component, and between the lower linkage slider and the second rotating component, under the working state of high-speed rotation drive of the eccentric wheel and reciprocating swing of the floating drive arm. This ensures that the sliding of the upper linkage slider along the first guide rail and the sliding of the lower linkage slider along the first guide rail are both stable and accurate. In turn, this ensures the transmission accuracy of the rotational motion of the eccentric wheel to the floating drive arm and then to the horizontal reciprocating motion of the main moving plate, further improving the stability and positioning accuracy of the entire machine's conveying.

[0015] Preferably, the paper feeding device further includes a plurality of paper-blocking mechanisms mounted on the frame and positioned above the discharge end of the paper conveying table. The plurality of paper-blocking mechanisms are arranged sequentially along the second guide slide rail. Each paper-blocking mechanism includes a paper-blocking frame fixed on the frame, a front-blocking cylinder fixed on the paper-blocking frame, and a first motor fixed on the frame. The output rod end of the front gear cylinder is fixed with a downward pressure paper block; The output end of the first motor is linked to a lead screw via a belt drive assembly. The two ends of the lead screw are rotatably positioned on the paper stop frame. The lead screw is threadedly connected to an adjusting sleeve. The adjusting sleeve is linked to an adjusting frame. A rear stop cylinder is fixed on the adjusting frame. The output rod of the rear stop cylinder is linked to a rear baffle. Several rear paper stop rods are fixed on the rear baffle. The paper feeding device also includes a paper pressing spring, one end of which is fixed to the frame and the other end of which is distributed above the paper conveying table.

[0016] By employing the above technical solution, several paper-blocking mechanisms and their rear paper-blocking rods arranged sequentially along the second guide rail block the front end of the paper when it enters the predetermined position between the clamping spring and the fixed clamping plate. This prevents the paper from moving too far forward due to conveying inertia and ensures that the paper stops at a position that the clamping robot can accurately grip, providing accurate initial positioning for subsequent hot stamping and die-cutting processes. Furthermore, the first motor drives the lead screw to rotate, and the adjusting screw sleeve drives the adjusting frame and the rear paper-blocking cylinder to adjust the position of the rear paper-blocking rod. This allows multiple paper-blocking mechanisms to automatically correct the direction of the paper, correcting any skewing that occurs during the conveying process and ensuring accurate paper conveying direction. Furthermore, the paper-pressing block driven by the front cylinder presses down on the paper surface, and the paper-pressing spring presses the paper from above, keeping the paper flat and reliably positioned on the paper conveying table. This prevents the paper from warping, shifting, or deviating before being gripped, thus ensuring that the gripping spring and fixed clamping plate of the clamping robot can accurately and stably grip the predetermined part of the paper, improving the positioning accuracy of paper conveying, and providing a reliable guarantee for the whole machine to achieve high-precision hot stamping and die-cutting positioning.

[0017] Preferably, a belt drive shaft is provided below each of the two ends of the paper conveying table, a paper conveying belt is linked between the two belt drive shafts, a drive source is connected to one of the belt drive shafts, and a paper pressing roller is provided above the end of the paper conveying table facing the upper paper table.

[0018] By adopting the above technical solution, a continuous and flat paper conveying plane is constructed through belt drive shafts located below both ends of the paper conveying table and a paper conveying belt linked between the two belt drive shafts. This allows the paper to move smoothly along the conveying direction on the paper conveying table, and the two ends of the paper conveying belt operate synchronously and are subjected to uniform force, ensuring a uniform and stable paper conveying speed. In addition, by setting a pressure roller above the end of the paper conveying table facing the upper paper table, the paper transferred by the paper suction flyer is pressed by the pressure roller when it enters the paper conveying belt. The pressure roller and the paper conveying belt work together to clamp and convey the paper, preventing the paper from warping, deviating, or shifting when it first enters the paper conveying table due to lack of restraint. This ensures that the paper can enter the conveying path accurately and smoothly and maintain the conveying direction, thereby providing a stable and reliable paper conveying guarantee for the positioning of the subsequent paper blocking mechanism and the accurate gripping of the clamping robot.

[0019] Preferably, the paper receiving device includes a liftable paper receiving platform and a paper feeding mechanism disposed above the paper receiving platform. The paper feeding mechanism includes a left paper feeding block and a right pusher plate disposed opposite to each other. The right pusher plate is linked to a right pusher cylinder fixed on the frame. A rear pusher plate and a front paper feeding assembly are disposed between the left paper feeding block and the right pusher plate, which are arranged opposite to each other. The rear pusher plate is linked to a rear pusher cylinder fixed on the frame. The front paper feeding assembly includes a mounting rod fixed on the frame, a first front paper feeding component sleeved on the mounting rod, and a front paper feeding seat sleeved on the mounting rod. A second front paper feeding component is fixed to the side of the front paper feeding seat away from the mounting rod.

[0020] Using the above technical solution, the paper falling into the receiving table is organized in four directions: left-side paper handling, right-side paper pushing, rear-side paper pushing, and front-side paper handling assembly. The right-side paper pushing cylinder drives the right-side paper pushing plate, and the rear-side paper pushing cylinder drives the rear-side paper pushing plate, applying lateral and longitudinal forces to the paper respectively. This ensures the paper is organized and aligned under the constraint of four directions, guaranteeing that the paper is neatly stacked and edge-aligned on the liftable receiving table, preventing the paper from scattering or misaligning, and facilitating subsequent packaging and processing. Furthermore, the front-side paper handling assembly includes a first front-side paper handling component sleeved on the mounting rod, a front-side paper handling seat sleeved on the mounting rod, and a fixed... The second front paper feeder is positioned on the side of the front paper feeder away from the mounting rod. When the paper size is small, the second front paper feeder and the front paper feeder can be selectively removed, and only the first front paper feeder is used to limit the front side of the paper to accommodate smaller paper sizes. When the paper size is large, the front paper feeder and the second front paper feeder are assembled on the mounting rod. During assembly, it is only necessary to keep the first and second front paper feeders at the same level to accommodate larger paper sizes. Thus, through the modular assembly method of the front paper feeder assembly, the paper feeding mechanism can flexibly adapt to different paper sizes, expanding the applicability of the equipment. At the same time, the structure is simple and the adjustment is convenient.

[0021] Preferably, a mold frame is detachably mounted on the frame and positioned above the paper receiving device. Several spaced positioning grooves are machined on both sides of the mold frame. A positioning rod is provided on the frame corresponding to each positioning groove. The positioning rod is detachably mounted on the frame by screws. Each positioning rod is rotatably connected to a first roller at its end facing the paper receiving device. Two sets of symmetrically arranged support arms are provided on the side of the mold frame away from the hot stamping and die-cutting device. A second roller and a third roller are provided at both ends of each support arm. A support plate fixed to the support arm is provided between the second roller and the third roller.

[0022] By adopting the above technical solution, the mold frame and the machine frame can be detached and installed separately. The mold frame does not participate in processing during normal operation of the hot stamping and die-cutting machine and can be removed at any time. It is only installed and used when it is necessary to clean or repair the stamping plate. This provides an operable carrier for the maintenance of the stamping plate without affecting normal processing. In addition, the positioning grooves arranged at intervals on both sides of the mold frame cooperate with the corresponding positioning rods on the machine frame to achieve accurate positioning of the mold frame on the machine frame. The first roller rotatably connected to the end of the positioning rod, and the second and third rollers at both ends of the support arm provide rolling support for the extraction or insertion of the stamping plate and the mold frame, reducing the frictional resistance during the extraction process. This allows the stamping plate to be extracted easily and smoothly, thus solving the problem of the small space inside the stamping carriage and the inability to reach in to clean the stamping plate. It reduces the difficulty and safety hazards of cleaning the stamping plate for operators and improves the convenience and safety of equipment maintenance.

[0023] The beneficial effects of this invention are as follows: On the one hand, the clamping robot mounted on the main moving plate continuously clamps the paper throughout the entire process of conveying and hot stamping die-cutting. The paper is always in a controlled state and is not released, avoiding paper displacement or deflection caused by the impact force of the template closing moment, paper springback, and equipment vibration. This effectively improves the hot stamping accuracy and die-cutting position accuracy and reduces the scrap rate. On the other hand, the eccentric wheel is directly driven by a servo motor, and the eccentric linkage drive mechanism composed of the upper linkage, floating drive arm, and lower linkage directly converts the rotational motion into the horizontal reciprocating motion of the main moving plate. The transmission path is significantly shortened and there are no intermediate flexible transmission links such as chains. This overcomes the problems of high energy loss, low transmission efficiency, and the gradual accumulation of gear meshing gaps leading to a decrease in transmission accuracy caused by multi-stage transmission in the prior art. It also avoids the impact of chain elastic deformation, wear elongation, polygonal effect, and vibration on the smoothness of conveying. This makes the overall structure simpler, the transmission more efficient, and the conveying smoother, meeting the positioning requirements of high-speed and high-precision hot stamping and die-cutting.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 14 The longitudinal hot stamping and die-cutting machine shown includes a frame 1 and a paper feeding device 2, a hot stamping and die-cutting device 3, a paper receiving device 4, and a material clamping and conveying device 5, all mounted on the frame 1.

[0029] The paper feeding device 2 includes a liftable paper loading platform 21, a paper conveying platform 22 located at the discharge end of the paper loading platform 21, and a paper suction flyer 23 located above the paper loading platform 21 for transferring paper from the paper loading platform 21 to the paper conveying platform 22. Belt drive shafts are respectively located below both ends of the paper conveying platform 22, and a paper conveying belt 27 is linked between the two belt drive shafts. One belt drive shaft is connected to a drive source, preferably a servo motor, for driving the paper conveying belt 27. A paper pressing roller 26 is located above the end of the paper conveying platform 22 facing the paper loading platform 21 to press the paper. Wheel 26 cooperates with paper conveyor belt 27 to clamp and convey the paper, allowing it to smoothly enter the conveying path of paper conveyor table 22 and preventing warping or deviation of the paper upon entry. The paper feeding device 2 also includes several paper blocking mechanisms 24 mounted on the frame 1 and positioned above the discharge end of paper conveyor table 22. The several paper blocking mechanisms 24 are arranged sequentially along the second guide rail 54. Each paper blocking mechanism 24 includes a paper blocking frame 241 fixed on the frame 1, a front blocking cylinder 242 fixed on the paper blocking frame 241, and a first motor 243 fixed on the frame 1. The output rod end of motor 42 is fixed with a pressing paper block 244, which is used to press down and hold the paper surface when the paper reaches a predetermined position. The output end of the first motor 243 is linked to a lead screw 246 through a belt drive assembly. The two ends of the lead screw 246 are rotatably positioned on the paper stop frame 241. The lead screw 246 is threadedly connected to an adjusting sleeve 247, which is linked to an adjusting frame 248. A rear stop cylinder 249 is fixed on the adjusting frame 248. The output rod of the rear stop cylinder 249 is linked to a rear baffle 2410, and several rear stops are fixed on the rear baffle 2410. The paper stop bar 245 is used to stop the front end of the paper when it enters the clamping position to prevent the paper from moving too far forward. At the same time, the first motor 243 adjusts the position of the paper stop bar 245 through the lead screw 246 and the adjusting screw sleeve 247, so that the multiple paper stop mechanisms 24 can automatically correct the direction of the paper. The paper feeding device 2 also includes a paper pressing spring 25. One end of the paper pressing spring 25 is fixed on the frame 1, and the other end of the paper pressing spring 25 is distributed above the paper conveying table 22 to apply a pressing force to the paper on the paper conveying table 22 from above, so as to prevent the paper from warping or shifting before being clamped.

[0030] The hot stamping and die-cutting device 3 is located on the side of the paper feeding table 22. The hot stamping and die-cutting device 3 includes an execution module 31, a main drive cylinder 32 that drives the execution module 31 to move vertically reciprocally, and a hot stamping and die-cutting worktable 33 fixed on the frame 1 and distributed below the execution module 31. A foil unwinding roller group 34 and a foil winding roller group 35 are respectively arranged on both sides of the execution module 31. When the main drive cylinder 32 drives the execution module 31 to move downward, it applies hot stamping or die-cutting pressure to the paper placed on the hot stamping and die-cutting worktable 33. At the same time, the foil unwinding roller group 34 unwinds the foil and the foil winding roller group 35 winds up the used foil, so that the foil is covered with the paper surface to complete the hot stamping process.

There are a second roller 435 and a third roller 436, and a support plate 437 fixed to the support arm 434 is provided between the second roller 435 and the third roller 436. The mold frame 43 can be left unmounted on the frame 1 during normal operation. It is only installed and used when the stamping plate needs to be cleaned or repaired. Positioning is achieved by the positioning groove 431 cooperating with the positioning rod 432. The first roller 433, the second roller 435 and the third roller 436 provide rolling support for the stamping plate to be pulled out or pushed in, which solves the problem of the small space inside the stamping car and the inability of people to reach in to clean the stamping plate.

Two clamping manipulators 52 are mounted on the main moving plate 51, arranged sequentially along the horizontal guide rail mechanism. The horizontal guide rail mechanism includes two parallel second guide rails 54. The main moving plate 51 slidably engages with the second guide rails 54 and reciprocates horizontally along the direction from the paper feeding device 2 to the paper receiving device 4 under the parallel guidance constraint of the two second guide rails 54, ensuring straightness and stability during movement. The eccentric linkage drive mechanism 53 includes a floating drive arm 531 and an eccentric wheel 532. The upper part of the floating drive arm 531 is rotatably connected to the main moving plate 51. The upper linkage 533 is slidably fitted in the middle of the boom 531, and the lower linkage 534 is slidably fitted in the lower part of the floating drive boom 531. The lower linkage 534 is rotatably positioned on the frame 1. The upper linkage 533 is eccentrically set on the eccentric wheel 532 and is rotatably connected to the eccentric wheel 532. A servo motor 535 that drives the eccentric wheel 532 to rotate is linked at the center of the eccentric wheel 532. The servo motor 535 is fixed on the frame 1. A U-shaped rotating seat 511 is fixed below the main moving plate 51. The upper part of the floating drive boom 531 is inserted into the middle of the U-shaped rotating seat 511, and the upper part of the floating drive boom 531 is rotatably connected to the U-shaped rotating seat 511 through a rotating shaft. The U-shaped rotating seat 511 provides double-sided support for the upper part of the floating drive boom 531, avoiding uneven force and torsion caused by single-sided cantilever support.

[0034] The floating drive arm 531 includes a floating drive plate 5311 and a first guide rail 5312 fixed to the floating drive plate 5311 by screws. The upper linkage member 533 includes an upper linkage slider 5331 and a first rotating member 5332 fixedly connected to the upper linkage slider 5331. The upper linkage slider 5331 slides with the first guide rail 5312. The eccentric wheel 532 has an eccentrically provided first linkage hole, and a first bearing 538 is provided in the first linkage hole. The end of the first rotating member 5332 away from the upper linkage slider 5331 is rotatably mounted at the first bearing 538, thereby converting the rotational friction between the upper linkage member 533 and the eccentric wheel 532 into rolling friction, reducing frictional resistance and improving transmission efficiency. The lower linkage member 534 includes a lower linkage slider 5341 and a second rotating member 5342 fixedly connected to the lower linkage slider 5341. The lower linkage slider 5341 slides with the first guide rail 5312. In a dynamic coordination mechanism, a mounting plate 536 is fixed on the frame 1 and positioned below the eccentric wheel 532. The mounting plate 536 has a second linkage hole, and a second bearing 537 is installed inside the second linkage hole. The end of the second rotating component 5342 away from the lower linkage slider 5341 is rotatably mounted in the second bearing 537, thereby rotatably mounting the lower linkage component 534 onto the frame 1 via the second bearing 537, forming a rotatable support fulcrum for the lower part of the floating drive arm 531. The upper linkage slider 5331 and the lower linkage slider 5341 both slide along the same first guide rail 5312, ensuring that the upper linkage component 533 and the lower linkage component 534 always maintain a collinear motion trajectory during the movement, avoiding interference and jamming. The floating drive plate 5311 has several first weight-reducing holes 5313, and the eccentric wheel 532 has several second weight-reducing holes 5321 that penetrate the eccentric wheel 532, used to reduce the inertial force during high-speed reciprocating motion.

[0035] The first rotating component 5332 has a first positioning groove 5333 on its end face facing the upper linkage slider 5331. The first positioning groove 5333 has a plurality of first screw holes 5334.

The second rotating component 5342 has a second positioning groove on its end face facing the lower linkage slider 5341. The second positioning groove has a plurality of second screw holes. The lower linkage slider 5341 is inserted into the second positioning groove and is fastened to the second screw holes by setting screws, so as to ensure that there is no loosening or relative displacement when the eccentric wheel 532 is rotating at high speed.

[0036] Each clamping robot 52 includes a clamping mounting base 521 fixed to the main moving plate 51 and a clamping cylinder 522 fixed below the clamping mounting base 521. Several clamping springs 523 are mounted above the clamping mounting base 521 and arranged sequentially along the second guide rail 54. A fixed clamping piece 524 is provided below each clamping spring 523 and is fixed to the clamping mounting base 521. One end of each clamping spring 523 is fixedly connected to the clamping mounting base 521, and the other end is connected to a connecting rod 525. This end is also provided with a bent clamping hook 528 for... The paper is hooked to the edge to form a hook-type anti-detachment constraint. The output rod of the clamping cylinder 522 is linked to the clamping lifting plate 526. The clamping lifting plate 526 is connected to several connecting rods 525 at the same time. The fixed clamping plate 524 has a strip-shaped clearance hole 527 corresponding to the connecting rod 525 to provide clearance space for the lifting and lowering action of the connecting rod 525. When the clamping cylinder 522 drives the clamping lifting plate 526 to lift or lower, the clamping lifting plate 526 simultaneously drives the free end of the corresponding clamping spring 523 to lift or press down through multiple connecting rods 525, so that the clamping hook 528 moves closer to or away from the fixed clamping plate 524, thereby realizing the clamping and release of the paper.

[0037] The clamping mounting base 521 includes an upper clamping fixing plate 5211 and a lower clamping fixing plate 5212 arranged on the side of the upper clamping fixing plate 5211. The upper clamping fixing plate 5211 is fixed to the upper surface of the main moving plate 51 by screws. The clamping spring 523 and the fixed clamping piece 524 are both installed on the upper clamping fixing plate 5211 to realize the partitioned arrangement of the clamping functional components. A connecting block 5213 is connected to the middle of the lower clamping fixing plate 5212. The connecting block 5213 is fixedly connected to the side of the main moving plate 51 by screws. A guide slider 5214 is installed on the side of the lower clamping fixing plate 5212. A third guide slider that slides with the guide slider 5214 is fixed on the frame 1. The third guide rail 5215 is set parallel to the second guide rail 54, so that the clamping robot 52 is simultaneously guided and constrained by the second guide rail 54 and the third guide rail 5215 during horizontal conveying, which enhances straightness and resistance to lateral forces. The clamping cylinder 522 is installed in the middle of the lower clamping fixed plate 5212. Guide sleeves 5216 are installed on both sides of the lower clamping fixed plate 5212. Each guide sleeve 5216 is slidably fitted with a guide rod 5217. The upper end of the guide rod 5217 is fixedly connected to the clamping lifting plate 526, ensuring that the clamping lifting plate 526 always rises and falls smoothly in the vertical direction without tilting under the drive of the clamping cylinder 522.

[0038] The overall working principle of this embodiment is as follows: The paper feeder 23 transfers the paper from the upper paper table 21 to the paper conveying table 22. The paper is then conveyed along the feeding direction to the predetermined position at the discharge end of the paper conveying table 22 by the paper pressure roller 26 and the paper conveying belt 27. The paper blocking mechanism 24's rear paper blocking rod 245 blocks the front end of the paper, the lower paper blocking block 244 presses down on the paper surface, and the paper pressing spring 25 presses the paper, completing the positioning and straightening of the paper at the paper feeding station. Subsequently, the clamping cylinder 522 of the clamping robot 52 drives the clamping lifting plate 526 to drive the clamping spring 523 to press down through the connecting rod 525. The clamping hook 528 hooks the edge of the paper and cooperates with the fixed clamping piece 524 to form an elastic clamp, clamping and fixing the paper. The servo motor 535 drives the eccentric wheel. 532 rotates, and the upper linkage 533 is eccentrically mounted on and rotatably connected to the eccentric wheel 532, transmitting the rotational motion of the eccentric wheel 532 to the floating drive arm 531. Simultaneously, the upper linkage 533 slides along the first guide rail 5312 in the middle of the floating drive arm 531, adaptively coordinating the relative pose changes between the rotation of the eccentric wheel 532 and the movement of the floating drive arm 531. The lower linkage 534 is rotatably positioned on the frame 1 and slides along the first guide rail 5312, forming a rotational fulcrum constraint at the lower part of the floating drive arm 531, causing the floating drive arm 531 to swing regularly around this fulcrum under the drive of the eccentric wheel 532. The upper part of the floating drive arm 531 is connected to the U-shaped rotating seat 5. 11 is rotatably connected to the main moving plate 51, transmitting the swing of the floating drive arm 531 to the main moving plate 51. Under the guidance and constraint of the main moving plate 51 slidingly engaged with the two second guide rails 54, the main moving plate 51 drives two clamping manipulators 52 arranged sequentially along the second guide rails 54 to move horizontally back and forth from the paper feeding device 2 to the hot stamping and die-cutting device 3 and then to the paper receiving device 4. The two clamping manipulators 52 work synchronously, cooperating alternately along the paper transport direction—the clamping manipulator 52 located in the paper feeding direction clamps the paper at the paper feeding device 2 and moves along the second guide rails 54 towards the hot stamping and die-cutting device 3, transporting the paper to the hot stamping and die-cutting worktable 33, while the other clamping manipulator 52 located in the paper receiving direction... After the paper is picked up at the hot stamping and die-cutting device 3, the clamping robot 52 continues to move along the second guide rail 54 toward the paper receiving device 4, releasing the paper to the receiving table 41. Thus, the alternating cooperation of the two clamping robots 52 realizes the one-way flow-through conveying of paper between the paper feeding station, the hot stamping and die-cutting station, and the paper receiving station, improving production efficiency. When the paper is clamped and conveyed to the hot stamping and die-cutting worktable 33 by the clamping robot 52, the main drive cylinder 32 drives the execution module 31 to apply downward pressure. At the same time, the foil unwinding roller group 34 and the foil winding roller group 35 cooperate to complete the foil lamination, realizing the hot stamping and die-cutting process. During the processing, the clamping robot 52 continuously clamps the paper without releasing it to prevent the paper from shifting.After processing, the clamping robot 52 continuously clamps the paper and transports it along the second guide rail 54 to the liftable receiving table 41 of the receiving device 4. The clamping cylinder 522 drives the clamping lifting plate 526 to lift the clamping spring 523 via the connecting rod 525. The clamping hook 528 releases the paper, which falls into the receiving table 41. The right push paper cylinder 423 of the paper feeding mechanism 42 drives the right push paperboard 422, and the rear push paper cylinder 426 drives the rear push paperboard 424. The paper is sorted and stacked in four directions: left paper feeding block 421, right push paperboard 422, rear push paperboard 424, and front paper feeding assembly.

[0039] During normal production of the hot stamping and die-cutting machine, the mold frame 43 is not installed on the frame 1, which does not affect the normal hot stamping and die-cutting process. When it is necessary to clean or repair the stamping plate of the hot stamping and die-cutting device 3, the mold frame 43 is installed on the frame 1, so that the mold frame 43 is located above the paper receiving device 4. The mold frame 43 is accurately positioned by the cooperation of the positioning groove 431 and the positioning rod 432. The stamping plate is placed on the support plate 437 and can be easily pulled out along the rolling direction of the first roller 433, the second roller 435, and the third roller 436. After the maintenance operation is completed, it can be pushed back, thereby solving the problem of the small space inside the stamping carriage and the inability of the hand to reach in to clean the stamping plate. At the same time, it does not affect the normal processing of the whole machine, thus completing the fully automated operation of paper feeding, hot stamping and die-cutting, and paper receiving.
