Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, specifically to a digital die-cutting and stripping device. Background Technology

[0002] Currently, digital die-cutting equipment is mainly used for die-cutting (full cut, half cut) and creasing of non-metallic materials, self-adhesive labels, EVA, double-sided tape, etc. In the industrial manufacturing field, strip-shaped materials are a common material receiving state. By winding strip-shaped materials into circular strips, the utilization rate of material storage space can be greatly increased. Strip-shaped material strips are also often used as a material carrier. By fixing various materials to the bottom material strip for support, centralized storage and transportation are facilitated.

[0003] For certain special materials, further processing on the material strip is required, such as label paper. After the strip of label paper is attached to the bottom material strip, it needs to be cut from the continuous strip structure into sheet-like structures for subsequent use. The cutting process generally uses die-cutting to complete the cutting of the label paper. For example, patent number 2023215088575 discloses a fully automatic feeding, die-cutting, peeling, and collecting machine, including a support mechanism, a feeding mechanism, a die-cutting mechanism, a winding mechanism, a peeling mechanism, and a collecting mechanism. The support mechanism is horizontally arranged and includes interconnected horizontal and vertical support surfaces; the feeding mechanism is located at one end of the vertical support surface of the support mechanism; the die-cutting mechanism is located on one side of the material strip exiting the feeding mechanism; the winding mechanism is located on one side of the material strip exiting the die-cutting mechanism; the peeling mechanism is located on one side of the material strip exiting the die-cutting mechanism. After die-cutting, the strip of die-cut material adhered to it enters the peeling mechanism, which peels the material off the strip; the collecting mechanism is located below the die-cutting mechanism. This invention integrates automatic feeding, die-cutting, stripping, and collection into one unit, effectively reducing the material conveying path during die-cutting, reducing its positional deviation, jamming, and surface wrinkles, and effectively improving die-cutting quality while improving die-cutting efficiency.

[0004] The aforementioned die-cutting methods have inherent defects: First, the die-cutting pattern is determined by a fixed die-cutting block. Once the product shape or size needs to be changed, the entire die-cutting block must be replaced, resulting in extremely poor equipment flexibility and an inability to meet the current demand for multi-variety, small-batch production. Second, traditional equipment lacks effective tension buffering and precise clamping and positioning mechanisms during the start-up, shutdown, and conveying of the conveyor belt. It is prone to positional shifts or wrinkles due to sudden changes in conveyor belt tension. Especially in the peeling process, the traditional fixed peeling plate is difficult to adapt to materials of different thicknesses and viscosities, and the peeling success rate needs to be improved.

[0005] Therefore, existing die-cutting and stripping equipment generally suffers from problems such as limited die-cutting modes, high changeover costs, inability to digitally cut complex shapes, insufficient strip tension control, and inadequate stripping accuracy. Furthermore, some equipment uses separate processes for die-cutting and stripping, resulting in material waste and slow changeover efficiency. Addressing these pain points, developing an automated device with high flexibility, high precision, and high efficiency has become a pressing technical challenge in this field. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing a digital die-cutting and stripping device. This solution overcomes the common issues of existing die-cutting and stripping equipment, such as limited die-cutting modes, high changeover costs, inability to digitally cut complex shapes, insufficient strip tension control and stripping accuracy, and the use of separate processes for die-cutting and stripping in some devices, resulting in material waste and slow changeover efficiency. By integrating digital trajectory cutting, dynamic tension buffering, and adaptive back-retreat stripping functions, this invention solves the problems of poor flexibility, high impact, unstable tension, and low stripping success rate of traditional equipment. By combining digital cutting and stripping functions, it effectively improves efficiency and reduces production costs.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows:

[0008] A digital die-cutting and stripping device includes: a chassis and a human-machine interface for controlling the operation of the device. The chassis is equipped with a feeding mechanism for placing materials and pulling and conveying the bonding strip, a digital die-cutting unit driven by the control system of the human-machine interface to cut the bonding strip into the required pattern or texture according to a set trajectory, and a retraction stripping mechanism for peeling the cut finished product from the strip. The feeding mechanism includes an upper film feeding assembly and a lower film feeding assembly for placing the material roll, a film pressing assembly for pressing the upper and lower film strips together and pulling them for the first time, a film clamping assembly to prevent the bonding strip from moving when the digital die-cutting unit is cutting, a pulling assembly for pulling the bonding strip a second time and peeling the upper film, and a waste collection assembly. The digital die-cutting unit is located between the film clamping assembly and the waste collection assembly.

[0009] Both the membrane clamping assembly and the waste collection assembly are equipped with buffer assemblies on their sides. The buffer assemblies are used to automatically buffer the material belt. They include a gravity tensioning component. The material belt passes through the gravity tensioning component, and the gravity tensioning component pulls the material belt down to the set position according to its own weight.

[0010] The digital die-cutting unit is equipped with two cutting head components, and the spacing between the two cutting head components is adjusted by a spacing adjustment component set on the Y-axis moving module.

[0011] The retraction stripping mechanism includes a feeder pulling assembly for pulling the lower film to move the sheet material toward the stripping slide. After the lower film passes over the top surface of the stripping slide, it folds down along the tip of the stripping slide and wraps around to the lower side of the stripping slide, where it connects with the feeder pulling assembly. When the strip advances on the stripping slide, the feeder retraction assembly drives the stripping slide to retract, while the feeder pulling assembly pulls the strip, causing the sheet material to be stripped from the lower film by the tip of the stripping slide and received by the stripping platform on the front side of the stripping slide. A take-up die assembly, driven by the feeder pulling assembly and used to take up the lower die, is provided on the side of the feeder pulling assembly.

[0012] Furthermore, the gravity tensioning component includes a vertically arranged guide rail and a gravity roller that is perpendicular to the guide rail and slidably connected to the guide rail. After being bonded, the bonding material strip passes around the bottom of the gravity roller and then passes through the film clamping assembly.

[0013] One end of the gravity roller is provided with a slider that slides in cooperation with the guide rail. The slider is provided with a connecting plate, and the connecting plate extends along the length direction to form an installation area. One end of the gravity roller is fixed in the installation area. The side wall of the connecting plate is provided with an L-shaped sensing plate.

[0014] Mounting strips are provided on the upper and lower sides of the guide rail, and the two mounting strips are parallel to the guide rail. The mounting strips have an inner groove along their length, and the inner groove has a sliding opening that communicates with the outside. The width of the sliding opening is smaller than the width of the inner groove. A slotted sensor that senses the L-shaped induction plate is provided on the sliding opening. The position of the slotted sensor can be adjusted up and down along the sliding opening.

[0015] Furthermore, the digital die-cutting unit includes a cutting platform fixed on the chassis. On the chassis on both sides of the cutting platform, there are X-axis moving modules and X-axis guide rails extending along the length of the cutting platform, respectively. The moving base of the X-axis moving module is provided with a truss that spans the cutting platform and slides across the X-axis guide rail. A Y-axis moving module is provided on the truss. Two cutting head components are provided on the Y-axis moving module, and the spacing is adjusted by a spacing adjustment component.

[0016] It also includes a cutter head height detection component, located on the side of the cutting platform, for detecting the cutter head height; the cutter head height detection component is electrically connected to the cutting cutter head component.

[0017] Furthermore, the cutting head component includes a movable seat mounted on the spacing adjustment assembly, and a Z-axis slide rail is provided on the movable seat; a movable block is slidably mounted on the Z-axis slide rail, and a cutting head is fixedly mounted on the side wall of the movable block. The movable block has a screw hole with its axis parallel to the Z-axis slide rail, and a Z-axis lead screw is connected in the screw hole. The movable seat is provided with a first servo motor whose output end is connected to the Z-axis lead screw; the first servo motor drives the Z-axis lead screw to rotate, so that the movable block drives the cutting head to move up and down along the Z-axis slide rail to adjust the height of the cutting head.

[0018] Furthermore, the spacing adjustment component includes an L-shaped moving plate fixed on a moving seat of the Y-axis moving module. The front side of the L-shaped moving plate is provided with a set of Y-axis guide rails, and the moving seats slide on the Y-axis guide rails. The upper side of the front side of the L-shaped moving plate is rotatably provided with a Y-axis bidirectional lead screw threaded to each moving seat. The side of the L-shaped moving plate is provided with a second servo motor whose output end is connected to the Y-axis bidirectional lead screw. The second servo motor drives the Y-axis bidirectional lead screw to rotate, driving the two moving seats to operate in opposite directions along the Y-axis guide rails to adjust the spacing between the two cutting heads.

[0019] Furthermore, the material pulling assembly includes two spaced-apart side plates, the front side edges of which are arc-shaped; a large-diameter roller is rotatably arranged between the two side plates, and one of the side plates is provided with a first drive motor whose output shaft is connected to the large-diameter roller via a coupling;

[0020] Two movable pressure roller components are provided on the arc-shaped side along the rotation direction of the large diameter roller to press the material strip against the surface of the large diameter roller. Upper film peeling blades are provided on the two side plates between the two movable pressure roller components.

[0021] The upper film peeler is equipped with a rotating rod that is rotatably connected to the two side plates. The two side plates are equipped with locking devices to lock the rotating rod. One end of the rotating rod is equipped with a lever for moving the rotating rod to move the tip of the upper film peeler away from or close to the surface of the large-diameter roller. The end face of the rotating rod along the axial direction is set as a plane, and the upper film peeler is installed on the plane.

[0022] Furthermore, the retraction stripping mechanism also includes a feeder clamping assembly for pressing the material strip and having the same structure as the film clamping assembly. When the feeder retraction assembly retracts, the feeder clamping assembly presses the material strip to prevent it from retracting. The feeder clamping assembly includes a frame and a slide bar assembly that slides on both sides of the top of the frame. The end of the slide bar assembly is provided with a pressure plate that can move up and down within the frame to press the material strip. The bottom surface of the pressure plate is provided with an elastic plate. The top of the frame is also provided with a pressing cylinder whose output end passes through the frame and is connected to the pressure plate.

[0023] Furthermore, the cutting platform has several adsorption holes for adsorbing the material strip, and the bottom surface of the cutting platform is equipped with a vacuum box corresponding to the adsorption holes. The vacuum box is connected to an external vacuum pumping device through a pipe.

[0024] Furthermore, the membrane pressing assembly includes a support plate and a support frame disposed opposite to the support plate. A main drive roller and a pressing roller that presses against and is driven by the main drive roller are provided between the support plate and the support frame. One end of the pressing roller is provided with a rotating handle for turning the pressing roller. A second drive motor that drives the main drive roller to rotate is provided on one side of the main drive roller.

[0025] The support plate and support frame have slots on the upper side that allow the two ends of the pressing roller to slide up and down. The two slots are provided with elastic pressing components that always push the pressing roller to press against the main drive roller.

[0026] The elastic pressing component includes a floating block connected to the pressing roller and slidably disposed in the slot, and a fixed block fixed on the port of the slot. The fixed block is provided with a guide slide shaft with one end extending into the slot and slidably connected to the floating block. The guide slide shaft is fitted with a compression spring that abuts against the floating block.

[0027] Furthermore, the feeder material pulling assembly includes a coating active roller rotatably located at the bottom of the frame, a driven pressing roller component that is pressed against the coating active roller and driven by the coating active roller to rotate and pull the lower film, and a motor and belt drive component that drive the coating active roller to rotate.

[0028] The driven pressing roller assembly includes a toggle connecting shaft located on the side of the rubber-coating drive roller. One end of the toggle connecting shaft is provided with a lever for rotating the toggle connecting shaft. A flipping frame is fixed on the toggle connecting shaft. The flipping frame is provided with a driven knurling roller that presses against the rubber-coating drive roller. When the driven knurling roller and the rubber-coating drive roller are pressed together, their shaft cores are located on the same horizontal plane.

[0029] The present invention has the following outstanding advantages over the prior art:

[0030] By installing a feeding mechanism, a digital die-cutting unit, and a retraction peeling mechanism on the chassis, the upper and lower film strips are placed on the upper and lower film feeding assemblies. The free ends of the upper and lower film strips sequentially pass through the film pressing assembly, buffer assembly, film clamping assembly, digital die-cutting unit, and pulling assembly. The free end of the upper film strip winds around to the waste collection assembly and is wound up by it. The free end of the lower film strip passes through the buffer assembly, feeder pressing assembly, and peeling assembly. The material slide and feeder assembly then wind the material around to the take-up die assembly, where it is wound up. During operation, the membrane pressing assembly pulls the upper and lower membrane strips, causing them to adhere together to form a bonded strip. Under the gravity of the clamping component, a section of material is buffered. Simultaneously, the bonded strip moves towards the digital die-cutting unit under the pull of the feeding assembly. When the bonded strip reaches the cutting position of the digital die-cutting unit, the membrane clamping assembly... The bonding material strip is pressed and positioned. At this time, the control system controls the digital die-cutting unit to drive the cutting head to move along the X, Y, and Z axes to cut the material into patterns or textures according to the set trajectory. After cutting, the film clamping assembly resets, causing the material pulling assembly to pull the bonding material strip again. When the cut bonding material strip passes the material pulling assembly, the upper film is wound up by the waste material collection assembly, and the upper film peeling knife peels the sheet from the upper film, so that the sheet is pulled by the lower film material strip. The lower film material strip passes through the buffer assembly, so that the buffer assembly buffers a section of material. The lower film material strip is moved to the peeling platform by the feeder pulling assembly and the lower die collection assembly. When the lower film material strip moves the sheet to the end of the peeling slide, the sheet is peeled out of the lower film, and the peeled part of the sheet is received by the peeling platform. At the same time, the feeder retraction assembly drives the peeling slide to retract, and the feeder pulling assembly pulls the material strip, so that the sheet is completely peeled from the lower film by the tip of the peeling slide, completing the material peeling.

[0031] By setting up a digital die-cutting unit, the cutting head cuts according to a preset trajectory, completely eliminating the limitations of fixed die-cutting blocks and realizing flexible digital cutting of any pattern. Changeover only requires calling the program, greatly reducing changeover costs and time. By configuring a gravity tension buffer component, the gravity roller's own weight is used to buffer the material strip tension in real time in a purely mechanical way, effectively absorbing the tension changes during the start-up, stop, and speed change of the material strip, preventing wrinkles and positional deviations. The film clamping component reliably clamps and positions the material strip during cutting, ensuring cutting accuracy. The movable pressure roller component on the feeding component and the upper film peeling blade work together to achieve stable peeling of the upper film. The retraction peeling mechanism drives the peeling slide to actively retract through the feeder retraction component, which, together with the continuous feeding of the feeder feeding component, forms an efficient relative peeling motion. The feeder clamping component presses the material strip during peeling, resulting in less impact on the material strip during the peeling process. This greatly improves the success rate and accuracy of peeling materials of different thicknesses and viscous materials. The overall equipment has a high degree of automation and operates stably and efficiently. This invention highly integrates functional modules such as precision pressing, digital dual-blade cutting, adaptive buffering, precise material pulling and waste removal, and high-performance retraction peeling and waste collection, forming an automated production line from roll material to finished sheet material. Its compact structure and reasonable layout effectively shorten the material conveyor path and reduce the cumulative error caused by long paths, thereby improving processing efficiency while ensuring long-term operational stability and product yield.

[0044] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0045] Please see Figures 1 to 10 This embodiment provides a digital die-cutting and stripping device, including a chassis 1 serving as the mounting base, and a human-machine interface 2 for operating the device and interacting with the machine. The chassis 1 integrates a complete automated production line, comprising a feeding mechanism 3 for storing and outputting upper and lower film strips, a digital die-cutting unit 4 for cutting the strips according to a digital path, and a retraction stripping mechanism 5 for automatically stripping and collecting the cut finished sheets from the lower film. Through the control system within the human-machine interface 2, the operating trajectory of the digital die-cutting unit 4 can be set and driven to achieve fully automated feeding, die-cutting, and stripping operations.

[0046] like Figure 3 As shown, the feeding mechanism 3 mainly consists of an upper film feeding assembly 31, a lower film feeding assembly 32, a film pressing assembly 33, a film clamping assembly 34, a pulling assembly 35, a waste collection assembly 36, and two buffer assemblies 37. The upper film feeding assembly 31 is used to hold the roll of material with the upper film (such as a laminate, protective film, or face material) wound on it, and the lower film feeding assembly 32 is used to hold the roll of material with the lower film (i.e., the bottom layer carrier film) wound on it. The film pressing assembly 33 is located downstream of both of them, and its function is to press the upper and lower film strips together into a bonding strip under a certain pressure, and to act as the initial power source to pull the two strips. The bonding strip then passes through the first buffer assembly 37 and enters the film clamping assembly 34. The digital die-cutting unit 4 is located between the film clamping assembly 34 and the waste collection assembly 36. During the cutting operation of the digital die-cutting unit 4, the film clamping assembly 34 firmly presses the bonding material strip onto the cutting platform 41 to prevent the strip from moving, thereby ensuring the accuracy of the cutting trajectory. After cutting, the film clamping assembly 34 is released, and the material pulling assembly 35 pulls the bonding material strip a second time to a fixed length. At the same time, the upper film peeling blade 355 on it peels the upper film off the bonding material strip. The peeled upper waste film is wound and recycled by the upper waste material collection assembly 36. On the side of the material pulling assembly 35, a second buffer assembly 37 is also configured to coordinate the speed difference between the intermittent pulling of the material pulling assembly 35 and the continuous or intermittent pulling of the retraction peeling mechanism 5.

[0047] like Figure 4 As shown, the retraction stripping mechanism 5 receives the strip containing only the lower film and cut sheet material after the upper film has been stripped. It mainly consists of a feeder clamping assembly 51, a feeder pulling assembly 52, a stripping slide 53, a feeder retraction assembly 54, a stripping platform 55, and a lower film receiving assembly 56. The lower film strip, carrying the cut sheet material, enters the retraction stripping mechanism 5, first passing through the feeder clamping assembly 51, and then resting on the top surface of the stripping slide 53. After passing around the tip of the stripping slide 53, the strip folds downwards, loops back from the underside of the stripping slide 53, is clamped by the feeder pulling assembly 52, and is pulled backwards. The feeder pulling assembly 52 provides stable traction, pulling the entire lower film strip forward. Simultaneously, as the sheet is partially peeled off at the tip, the feeder retraction assembly 54 drives the peeling slide 53 to move in the opposite direction (retract), while the feeder pulling assembly 52 continues to pull, preventing the sheet from bending downwards with the lower film at the tip. The sheet is then forcibly peeled off and falls naturally onto the peeling platform 55, completing the automatic take-up. The unloaded lower film after peeling is then wound up by the take-up assembly 56, which is located to the side of the feeder pulling assembly 52 and driven by it.

[0048] like Figure 5 As shown, before cutting, the upper and lower film strips are bonded together by the film bonding assembly 33 so that the digital die-cutting unit 4 can cut them. The specific structure of the film bonding assembly 33 includes a support plate 331 and a support frame 339 parallel to it. A main drive roller 333, driven by a second drive motor 332 via a belt or chain, is installed between the support plate 331 and the support frame 339, along with a pressing roller 334 parallel to and elastically pressed against the main drive roller 333. Vertical slots 335 are machined on the top of the support plate and the support frame 339, and the two ends of the pressing roller 334 pass through the slots 335, allowing them to slide up and down within the slots 335.

[0049] In addition, one of the buffer components 37 is disposed on the support plate 331, and the upper film feeding component 31 and the lower film feeding component 32 are respectively disposed on the upper and lower sides of the support plate 331.

[0050] To allow the pressing roller 334 to move up and down at the slot 335, moving it away from or close to the main drive roller 333, an elastic pressing component is installed in each slot 335. This elastic pressing component includes a floating block 336 rotatably connected to the shaft of the pressing roller 334, and a fixed block 337 fixed to the top end of the slot by screws. A guide shaft 338 is vertically fixed to the fixed block 337, extending into the slot and slidingly engaging with a hole in the floating block 336. A compression spring is fitted on the guide shaft 338, with its two ends abutting against the fixed block 337 and the floating block 336 respectively, thereby generating an elastic force that always presses the pressing roller 334 downward against the surface of the main drive roller 333. One end of the pressing roller 334 is also fixed with a rotating handle 330. When material needs to be fed or cleaned, the rotating handle 330 can be turned upwards to lift the pressing roller 334 by overcoming the spring force through the eccentric mechanism or by directly lifting it, making it easier for the material strip to pass through. Turning the rotating handle 330 back will automatically press the pressing roller 334 back by the spring force. During operation, the second drive motor 332 rotates, driving the main drive roller 333, which drives the pressing roller 334 to rotate synchronously by friction. The two layers of material strip are evenly squeezed and bonded when passing through the pressing line between the two rollers. The setting of the elastic pressing component can not only adapt to the total thickness variation of the material strip within a certain range, but also play a role in buffering and absorbing vibration, ensuring constant pressing force, and the bonded material strip is flat and free of air bubbles, ensuring the quality of the sheet material cut in the subsequent process.

[0051] like Figure 6 As shown, the buffer component 37 is crucial in this invention for maintaining stable tape tension and preventing positional shifts or wrinkles caused by instantaneous impacts. Specifically, this gravity tensioning component includes a set of guide rails 371 vertically fixed to the wall panel of the housing 1, and a gravity roller 373 perpendicular to the guide rails 371 and slidably engaged with a slider 372. The gravity roller 373 itself has sufficient weight. During tape feeding, the tape wraps around the bottom of the gravity roller 373. Utilizing its own weight, the gravity roller 373 naturally droops, tensioning the tape downwards and buffering a certain length. When the rear-end pulling component 35 or feeder pulling component 52 pulls the tape rapidly and instantaneously, the tape tension increases abruptly. The tape overcomes the weight of the gravity roller 373, lifting it upwards along the guide rails 371, thereby releasing the previously buffered tape length, compensating for the displacement requirements during the pulling process, and preventing the tape from being pulled too hard and causing tensile deformation or breakage. When the material feeding stops or the speed decreases, the tension of the material belt decreases, and the gravity roller 373 descends again under its own weight to reabsorb the slack material belt, keeping the material belt taut at all times and eliminating the risk of slack and sagging.

[0052] To monitor the position of the gravity roller 373, a connecting plate 374 is fixed to the slider 372. A portion of the connecting plate 374 extends along its length out of the mounting area, and the shaft end of the gravity roller 373 is fixed to this mounting area. An L-shaped sensing plate 375 is also fixed to the side wall of the connecting plate 374. Two mounting strips 376 are fixed vertically and horizontally to the side of the guide rail 371. Each mounting strip 376 has a T-shaped or dovetail-shaped inner groove, which communicates with the outside through a sliding opening narrower than the inner groove width. A slotted sensor 377, whose position can be adjusted vertically along the sliding opening, is installed on the sliding opening. When the gravity roller 373 moves the L-shaped sensing plate 375 vertically into the optical path of the slotted sensor 377, a signal is triggered. By adjusting the positions of the two slotted sensors 377, the upper and lower limits of the gravity roller 373's movement can be set. When the conveyor belt runs out or breaks, the gravity roller 373 will fall to the bottom, triggering the lower limit sensor, and the system can alarm and stop. When the conveyor belt is jammed or the tension is too high, pulling the roller to the highest point, triggering the upper limit sensor, it can also take protective action. This design utilizes the conveyor belt's own gravity for adaptive tension adjustment, requiring no external power such as motors or cylinders. It has a simple structure, high reliability, and the adjustable position sensor allows for flexible adaptation to different tension requirements and conveyor belt materials, greatly improving the equipment's adaptability to material differences.

[0053] After the upper and lower film strips are pressed and bonded together by the film pressing assembly 33, the bonding material strip is pulled to the digital die-cutting unit 4 by the material pulling assembly 35 for die-cutting. Before die-cutting in the digital die-cutting unit 4, the film clamping assembly 34 presses the bonding material strip together and, together with the material pulling assembly 35, straightens the bonding material strip to prevent wrinkles or movement during cutting, thereby improving the accuracy of die-cutting and the quality of the material.

[0054] like Figure 3 and Figure 7 As shown, the film clamping assembly 34 is used to press the bonding strip onto the cutting platform 41 during cutting by the digital die-cutting unit 4. It employs a cylinder-driven pressure plate structure, specifically including a frame 341 and sliding rod assemblies 342 mounted on both sides of the top of the frame 341 and capable of sliding up and down. A pressure plate 343 is connected to the lower end of the sliding rod assembly 342. The sliding rod assembly 342 slides in conjunction with the frame 341 via linear bearings. An elastic plate 344, which can be made of urethane or polyurethane, is attached to the bottom surface of the pressure plate 343. A downward-pressing cylinder 345 is fixed to the top of the frame 341, and its piston rod passes through the frame 341 and is fixed to the pressure plate 343.

[0055] In other words, just before the digital die-cutting unit 4 begins cutting, the pressing cylinder 345 actuates, pushing the pressure plate 343 downwards. The elastic plate 344 contacts the bonding strip and deforms, providing uniform and sufficiently large frictional force to prevent the bonding strip from moving in the XY direction within the plane. The pulling assembly 35 then tightens the bonding strip, and the elastic contact prevents damage or scratching of the strip surface. After cutting, the pressing cylinder 345 retracts, and the pressure plate 343 lifts to release the bonding strip. This clamping action, coordinated with the cutting, effectively solves the problem of micro-displacement caused by auxiliary airflow, vibration, or the release of internal stress in the strip during cutting, ensuring micron-level cutting repeatability and clean, burr-free cutting edges.

[0056] like Figure 8 and Figure 9 As shown, the digital die-cutting unit 4 is used to die-cut the bonding strip. The die-cutting path is preset by the operator on the control system, which then controls the digital die-cutting unit 4 to perform the die-cutting according to the preset path. The digital die-cutting unit 4 includes a planar cutting platform 41 fixed to the housing 1. On both sides of the cutting platform 41, on the housing 1, are respectively installed an X-axis moving module 42 extending along the length direction of the platform (defined as the X-axis) and an X-axis guide rail 43 that provides auxiliary support and guidance. The X-axis moving module 42 is typically a lead screw guide module, with its moving base driven by a servo motor. A rigid truss 44 spans above the cutting platform 41, one end of which is fixed to the moving base of the X-axis moving module 42, and the other end is slidably supported on the X-axis guide rail 43 via a slider. A Y-axis moving module 45 is mounted on the truss 44, and the Y-axis moving module 45 is also servo-driven.

[0057] Two sets of cutting head components 46 are provided on the Y-axis moving module 45. The two sets of cutting head components 46 are adjusted in the Y-axis direction by a set of spacing adjustment components 47 to adapt to the cutting of different widths of the panel or to cut two workpieces at the same time, thereby doubling the cutting efficiency.

[0058] Specifically, in this embodiment, the cutting head component 46 comprises a movable base 461 driven by a spacing adjustment assembly 47. A vertical (Z-axis) Z-axis slide rail 462 is fixed to the front of the movable base 461. A movable block 463 is slidably fitted onto the Z-axis slide rail 462, and a cutting head 464 is fixed to the side wall of the movable block 463 via a bracket. A threaded hole parallel to the Z-axis slide rail 462 is machined on the movable block 463, and a Z-axis lead screw 465 is screwed into the threaded hole. A first servo motor 466 is mounted on the top of the movable base 461, and its output shaft is connected to the Z-axis lead screw 465. When the first servo motor 466 is rotated under control, the Z-axis lead screw 465 rotates, driving the movable block 463 to precisely raise and lower the cutting head 464 along the Z-axis slide rail 462. Cutting requires maintaining the optimal position on the material surface; the cutting head height needs to be adjusted accordingly for materials of different thicknesses.

[0059] In one embodiment, the spacing adjustment assembly 47 includes an L-shaped movable plate 471. The back of the L-shaped movable plate 471 is fixed to the movable seat of the Y-axis movable module 45, and a set of parallel Y-axis guide rails 472 are horizontally arranged on its front side. Two movable seats 461 are slidably mounted on the two Y-axis guide rails 472 via sliders. Above the front side of the L-shaped movable plate 471, a Y-axis bidirectional lead screw 473 extending along the Y-axis direction is rotatably arranged. The left and right ends of the lead screw are machined with threads in opposite directions, which are threadedly connected to nuts on the two movable seats 461 respectively. A second servo motor 474 is fixed to the end of the L-shaped movable plate 471, and its output end is connected to the Y-axis bidirectional lead screw 473. When the second servo motor 474 drives the Y-axis bidirectional lead screw 473 to rotate, because the threads at both ends are reversed, the two movable seats 461 will move synchronously closer to each other or synchronously move away from each other along the Y-axis guide rails 472, thereby symmetrically adjusting the spacing between the two cutting heads 464. This setting allows operators to simply input the layout spacing on the human-machine interface 2, and the equipment will automatically adjust the position of the dual cutter heads. There is no need for tedious manual disassembly and alignment, and the line change speed is extremely fast, making it especially suitable for high-efficiency production modes such as one-to-one or one-to-two outputs.

[0060] In one embodiment, to compensate for variations in material thickness or to ensure the accuracy of the cutting head height position after each material change, this equipment also includes a cutting head height detection component 48. For example... Figure 7As shown, the cutter head height detection component 48 is installed on the side edge of the cutting platform 41. It can be a contact-type tool setter or a displacement sensor, and its signal is electrically connected to the control system of the first servo motor 466. In the automatic cutter head height adjustment program, the cutting cutter head 464 moves above the cutter head height detection component 48, and the Z-axis drives the cutter head to slowly descend. When the tip of the cutter head touches the contact of the cutter head height detection component 48 or reaches the set displacement value, the system records the current Z-axis coordinate and automatically calculates the surface height of the material to be processed according to the preset parameters. The first servo motor 466 can then automatically adjust the cutting cutter head 464 to the required height. This automated process eliminates the tediousness and experience dependence of manual cutter head height adjustment, ensuring the consistency of cutting quality between the first piece and the batch.

[0061] The cutting platform 41 serves as the supporting reference surface during cutting, and its flatness and stability directly affect the cutting quality. Therefore, the upper surface of the cutting platform 41 is densely covered with several adsorption holes, and the bottom surface of the cutting platform 41 is equipped with a vacuum box communicating with the adsorption holes. The vacuum box is connected to an external vacuum pumping device via a pipe. Simultaneously or before the membrane clamping assembly 34 presses the material strip, the vacuum pumping device is activated, generating negative pressure in the adsorption holes, firmly adsorbing and flattening the material strip onto the cutting platform 41. Through this dual fixing method—clamping on all four sides and vacuum adsorption at the bottom—the local flatness of the material strip is maximized, completely eliminating the problem of uneven cutting depth caused by material strip warping or local bulging.

[0062] After the digital die-cutting unit 4 completes the cutting, the film clamping assembly 34 releases, and the material pulling assembly 35 continues to operate, pulling out the cut strip section and simultaneously peeling off the upper film. Figure 11 As shown, the feeding assembly 35 has two spaced-apart side plates 351, and another buffer assembly 37 is disposed on one of the side plates 351. The front edges of both side plates 351 are designed to be arc-shaped. A large-diameter roller 352 is rotatably disposed between the two side plates 351. The upper surface of the large-diameter roller 352 is on the same horizontal plane as the top surface of the cutting platform 41 to pull the bonding strip and avoid wrinkles in the bonding strip due to uneven height. A first drive motor 353 is fixed on one of the side plates 351, and its output shaft directly drives the large-diameter roller 352 to rotate through a coupling. Two movable pressure roller components 354 are arranged on the arc-shaped front edges of the two side plates 351, and the material strip is pressed against the surface of the large-diameter roller 352 by the movable pressure roller components 354. When the first drive motor 353 drives the large-diameter roller 352 to rotate at a set angle, the bonding strip can be moved forward by one step.

[0063] In one embodiment, movable grooves are formed on both side plates 351. The movable pressure roller component 354 includes a small pressure roller with guide sliders at both ends that can slide axially along the movable groove. A connecting block is fixed at the top of the groove opening, and a guide rod is provided on the connecting block, which slides through the connecting block and is connected to the guide slider. A spring is provided on the upper part of the guide rod, which contacts the end face of the guide slider. A handle is provided on one side of the small pressure roller, and the small pressure roller is rotated by turning the handle. In addition, U-shaped blocks are fixed on both side plates 351 near the bottom of the movable groove. U-shaped notches are formed at both ends of the small pressure roller. When the small pressure roller is rotated, the U-shaped notches are inserted into the U-shaped blocks, and the spring pushes the small pressure roller to press the material strip tightly against the arc surface of the large diameter roller 352. Since the pressure rollers are distributed on both sides of the arc, the wrap angle of the material strip with the large diameter roller 352 is extremely large, and the friction is also very large, so slippage will not occur during the material pulling process.

[0064] To peel off the upper film and prevent the cut sheet from peeling off along with it, allowing the sheet to move with the lower film, an upper film peeling knife 355 is installed in the side plate 351 area between the two movable pressure roller components 354. The upper film peeling knife 355 is rotatably connected between the two side plates 351 via a rotating rod 356. The rod end of the rotating rod 356 extends beyond the side plate 351 and is equipped with a lever handle. Locking elements (such as locking screws) are provided on the two side plates 351 to lock the angle of the rotating rod 356. A flat surface is machined along the axial direction of the rotating rod 356, and the upper film peeling knife 355 is fixed to this surface. By turning the lever handle, the distance and cutting angle between the blade of the upper film peeling knife 355 and the surface of the large-diameter roller 352 can be changed. As the laminating strip is pulled by the large-diameter roller 352 past the tip of the upper film peeling blade 355, the upper film strip is deflected upwards by the blade tip and eventually wound up to the waste collection assembly 36. Meanwhile, the attached sheet material, under the action of the upper film peeling blade 355, continues to move along the roller surface with the lower film, thus peeling off the upper film. Since the gap between the blade and the roller surface can be finely adjusted by the rotating rod 356, it can adapt to the peeling requirements of upper films of different thicknesses, from extremely thin films to thicker coatings, without problems such as continuous peeling or scratching of the sheet material.

[0065] In one scheme, such as Figure 12As shown, the waste collection assembly 36 is used to collect the film-coating waste. This assembly is positioned above the material pulling assembly 35 and includes a vertical frame 360. Inside the vertical frame are a magnetic powder clutch 361, a drive motor 362 connected to the main shaft of the magnetic powder clutch 361 via a synchronous belt, and a hand-operated shaft 363 connected to the other end of the main shaft of the magnetic powder clutch 361 via another synchronous belt. The hand-operated shaft 363 is fixed to the upper end of the vertical frame 360 ​​by a block, and the block has a bearing assembly connected to the hand-operated shaft 363. Baffles 364 are provided at both ends of the hand-operated shaft 363. The drive motor 362 drives the main shaft of the magnetic powder clutch 361 to rotate, thereby causing the hand-operated shaft 363 to rotate and collect the film-coating waste.

[0066] In one embodiment, a spare feed shaft 365 is provided on the side of the waste collection assembly 36, and the feed shaft 365 is installed on the retraction stripping mechanism 5. The spare feed shaft 365 allows the next roll of raw material to be processed to be pre-loaded onto the spare feed shaft after the waste roll has been replaced in a single processing task, eliminating the need to stop the machine to complete the material replacement and preparation. This effectively reduces the equipment's standby time and improves the continuous processing efficiency of the entire machine.

[0067] When the strip, having had its upper film removed, carries the sheet material into the retraction peeling station, it is crucial to ensure the stability of the strip during the later stages of the peeling process. Therefore, a feeder clamping assembly 51 is installed. The structure of the feeder clamping assembly 51 is identical to that of the aforementioned film clamping assembly 34, also including a frame, a slide bar assembly, a pressure plate with an elastic plate, and a pressing cylinder. Just before the feeder retraction assembly 54 is about to retract, the pressing cylinder of the feeder clamping assembly 51 extends, pressing the strip firmly against the reference surface of the frame. Because the peeling slide 53 exerts a backward pulling force on the strip during retraction, if it is not clamped, the entire strip may be dragged backward, causing wrinkles at the cutting station or pulling back the peeled sheet material. The feeder clamping assembly 51 thus serves to fix the strip in place.

[0068] In this embodiment, as Figure 4 and Figure 10As shown, the feeder pulling assembly 52 is the power source for pulling the lower film. It includes a coating drive roller 521 rotatably mounted at the bottom of the feeder pressing assembly 51 frame, and a driven pressing roller component 522 that can be pressed or separated from it. The coating drive roller 521 is driven to rotate by a motor and belt drive component 523. The driven pressing roller component 522 specifically includes a toggle connecting shaft 5221 located on the side of the coating drive roller 521. One end of the toggle connecting shaft 5221 extends out of the wall plate and is fixed with a lever 5222. The lever 5222 can be manually moved to rotate the toggle connecting shaft 5221 by a certain angle. A flipping frame 5223 is fixed on the shaft of the toggle connecting shaft 5221, and a driven knurling roller 5224 is rotatably mounted on the flipping frame 5223. When material feeding is required, the lever 5222 is moved, causing the flipping frame 5223 and the driven knurling roller 5224 to flip upwards, away from the coating drive roller 521, leaving a feeding gap. After the lower film passes around the peeling slide 53, it is pulled between the two rollers, and then the lever 5222 is reversed, causing the driven knurling roller 5224 to fall and press against the coating drive roller 521. At this time, since the axes of the driven knurling roller 5224 and the coating drive roller 521 are exactly on the same horizontal plane, they can form a stable and well-aligned pressing line, and the material strip is clamped in it. When the motor and belt drive component 523 drives the coating drive roller 521 to rotate, it drives the driven knurling roller 5224 to rotate through friction, thereby pulling the clamped lower film, providing a stable and precise feeding step, and at the same time driving the lower film take-up assembly 56 to wind up the lower film waste.

[0069] The stripping slide 53 is a plate-shaped or block-shaped part with a sharp leading edge. The lower film strip is conveyed from back to front, passes over the top surface of the stripping slide 53, rounds a very small corner at the tip, and then folds down almost 180 degrees to the bottom of the stripping slide 53 before connecting to the feeder pulling assembly 52. ​​The feeder retraction assembly 54 can be a cylinder or a lead screw module driven by a servo motor. Its moving end is connected to the stripping slide 53, enabling it to drive the stripping slide 53 to make a short-stroke, rapid movement in the opposite direction of the strip conveying (retraction).

[0070] The specific coordination and principle of the aforementioned retraction stripping mechanism 5 are as follows:

[0071] When the feeder assembly 52 pulls the feeder forward one step, and the first cut sheet is placed at the tip edge of the stripping slide 53, the control system issues a command.

[0072] First, the feeder clamping assembly 51 clamps the material belt, causing the stripping slide 53 to move the sheet material on the material belt from the stripped portion to the stripping platform 55, so that the stripping platform 55 receives the sheet material.

[0073] Subsequently, the feeder retraction component 54 moves instantly, driving the stripping slide 53 to move backward a small distance with a certain acceleration.

[0074] At this time, because the feeder pulling assembly 52 maintains a constant tension in clamping the lower film, the lower film is still subjected to a backward tension below the peeling slide 53. However, because the tip of the peeling slide 53 pulls the lower film and sheet material covering it backward together, the sheet material, due to its own rigidity and the edge not adhered to the lower film, cannot follow the lower film to make a sharp downward bending motion around the tip. Its front end is scooped up by the tip and separated from the lower film. The peeling platform 55 receives the sheet material, and then the sheet material on the peeling platform 55 is removed by manual labor or the conveying mechanism of the next station.

[0075] After the sheet is peeled off, the feeder retraction assembly 54 resets, and the feeder pulling assembly 52 immediately pulls the lower film forward one step, sending the next sheet to the tip. By actively retracting the peeling slide 53, the peeling plate is effectively pulled away from under the sheet, greatly reducing the instantaneous peeling angle and peeling force, making the peeling process extremely gentle and with a high success rate.

[0076] After being peeled off, the lower film is wound up by the lower film take-up assembly 56 after passing over the coating drive roller 521. The lower film take-up assembly 56 is linked to the drive part of the feeder feeding assembly 52 via gears or belts to ensure that the winding speed is synchronized with the feeding speed and maintain constant tension of the lower film.

[0077] This invention ensures absolute flatness and precise positioning of the material strip during conveying and cutting by using the film pressing, gravity buffering, and film clamping of the feeding mechanism 3. The digital die-cutting unit 4, with its dual-blade head, three-axis linkage, and adsorption platform, achieves flexible and efficient cutting of arbitrary shapes, and ensures cutting accuracy by automatically adjusting the blade height. The material pulling assembly 35 and the upper film peeling blade 355 reliably peel off the upper film and effectively recycle it. The retraction peeling mechanism 5 effectively peels off the sheet material with extremely low stress through the cooperation of feeder pressing, feeder pulling, and active retraction of the peeling slide. This invention, through the organic integration of a series of mechanical and CNC technologies, fundamentally solves the inherent defects of traditional equipment, such as single die-cutting mode, high changeover cost, inability to cut complex shapes, poor tension control, and low peeling accuracy, achieving the expected goals of high flexibility, high precision, and high efficiency.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
