Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a multi-layer stacked material synchronous cutting device. Background Technology

[0002] In light industries such as packaging, footwear materials, apparel, and electronics, the cutting and processing of flexible materials is one of the core processes, and corresponding cutting devices are widely used. Currently, the mainstream products on the market include hydraulic cutting machines, laser cutting machines, ultrasonic cutting machines, and traditional mechanical cutting machines. Among them, hydraulic cutting machines dominate due to their stability advantage, laser cutting machines are suitable for precision cutting scenarios, and ultrasonic cutting machines are mostly used for processing needs that avoid burrs on edges. However, these devices all have obvious technical defects and are difficult to meet the high-efficiency integration requirements of modern production.

[0003] Existing flexible material cutting devices focus solely on material cutting, generally lacking integrated designs for simultaneous material feeding and stacking of the cut materials. During the cutting process, the flexible material must be transported manually or with additional feeding equipment. After cutting, the cut materials need to be manually collected, sorted, and stacked, which not only increases the intensity of manual labor but also makes the material prone to shifting and wrinkling due to human intervention, affecting cutting accuracy and subsequent processing efficiency.

[0004] Meanwhile, most existing devices can only perform single-layer flexible material cutting operations and cannot adapt to the simultaneous cutting of multi-layer materials, resulting in limited applications. For scenarios requiring batch processing of multi-layer flexible materials, the single-layer cutting process must be repeated multiple times, significantly reducing production efficiency. Furthermore, cutting multiple layers individually is prone to dimensional deviations, affecting product consistency.

[0005] The aforementioned problems result in low functional integration and low automation levels in existing flexible material cutting devices. This not only increases production processes and labor costs but also limits their application in batch processing and high-precision processing scenarios, failing to meet the current demand in the flexible material processing field for efficient, integrated, and multifunctional equipment. Therefore, developing a flexible material cutting device that can integrate cutting, synchronous material guiding, and material stacking, and is adaptable to multi-layer cutting, has become an urgent technical problem to be solved in this field. Summary of the Invention

[0006] The technical problem that this invention aims to solve is that existing flexible material cutting devices have low functional integration and low automation levels, which not only increases production processes and labor costs, but also limits their application in batch processing and high-precision processing scenarios, and cannot meet the current demand in the field of flexible material processing for efficient, integrated, and multifunctional equipment.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: a multi-layer stacked material synchronous cutting device, including a main frame, with rotating lateral guide roller groups movably mounted on both sides of the upper end of the main frame, and a top-suspended transverse cutting component and an electrically controlled translational guiding device movably mounted inside the main frame via a transverse guide rail. Several optical measuring components for monitoring material tension are fixedly mounted on the inner side wall of the main frame, and an electrically controlled stacking device is provided at the lower end of the main frame. The rotating lateral guide roller groups guide the material to the main frame, the electrically controlled translational guiding device pulls the material laterally, the top-suspended transverse cutting component cuts the material, and after cutting, the electrically controlled stacking device automatically stacks the material and completes the unloading process. The optical measuring components monitor the material tension in real time and provide feedback for adjustment, realizing integrated cutting, guiding, and stacking operations.

[0008] Furthermore, the upper end of the main frame has outwardly protruding lateral assembly shafts on both sides. The rotating lateral guide roller assembly includes a flipping bushing movably mounted on the lateral assembly shaft, lateral assembly frames installed on both sides of the flipping bushing, a first electrically controlled guide roller and a second electrically controlled guide roller movably mounted on the ends of the lateral assembly frames, and an angle adjustment support rod for controlling the flipping of the lateral assembly frames. The guide angle and height can be flexibly adjusted according to the material specifications to meet the needs of guiding multi-layer materials.

[0009] Furthermore, a forward-protruding horizontal assembly plate is fixedly installed inside the main frame, and the upper end of the horizontal guide rail is fixedly installed with the lower surface of the horizontal assembly plate. Each horizontal guide rail is equipped with an electrically controlled lead screw, which provides stable lateral movement guidance and power for the top-mounted horizontal cutting assembly and the electrically controlled translational material guiding device.

[0010] Furthermore, the top-mounted horizontal cutting assembly includes a first horizontal assembly frame threaded onto an electric control screw, an upper magnetic control cutting blade slidably mounted on the top surface of the first horizontal assembly frame, and a lower magnetic control cutting blade slidably mounted on the bottom surface of the first horizontal assembly frame. It adopts a bidirectional cutting design to ensure that multi-layer materials are cut smoothly and avoid burrs on the edges.

[0011] Furthermore, the electrically controlled translational material guiding device includes a second horizontal assembly frame threaded onto an electrically controlled lead screw, and magnetically controlled clamping modules installed on both sides inside the second horizontal assembly frame, which can stably clamp the material and pull it laterally to ensure the flatness of the material during cutting and improve cutting accuracy.

[0012] Furthermore, longitudinal guide rails are provided on the upper end of one side and the lower end of the other side of the first horizontal assembly frame. The upper and lower magnetic control cutting blades are composed of an electromagnet, an iron spring, a lateral extrusion block and a horizontal blade installed inside the longitudinal guide rail. The extension and retraction of the cutting blade are controlled by the electromagnet to achieve precise cutting, and the iron spring can play a buffering and reset role to protect the blade and the material.

[0013] Furthermore, an embedded lifting guide rail is fixedly mounted on the lower front of the main frame, and an electrically controlled lifting screw is movably mounted inside the embedded lifting guide rail to provide lifting power for the electrically controlled stacking device, adapting to stacking requirements of different heights.

[0014] Furthermore, the electrically controlled stacking device includes an internally threaded lifting frame threaded onto an electrically controlled lifting screw, an upper extension seat slidably mounted on the upper end of the internally threaded lifting frame, an inner translational support rod fixed inside the internally threaded lifting frame, and an embedded pressure detection plate mounted on the upper surface of the upper extension seat. It can automatically receive the cut materials and stack them neatly. The pressure detection plate can monitor the stacking thickness and trigger the feeding action in a timely manner.

[0015] Furthermore, the angle-adjustable strut controls the rotation of the lateral assembly frame via telescopic control. The rotation angle of the lateral assembly frame is 0°-90°, which can be flexibly adjusted according to the material thickness and material guiding requirements to adapt to the material guiding needs of different scenarios.

[0016] Furthermore, several inverted L-shaped internal supports for fixing optical measurement components are fixedly mounted on the lower surface of the horizontal assembly plate. Arc-shaped adjustment seats are fixedly mounted on the inner side of the internal supports. The optical measurement components are inserted into the arc-shaped adjustment seats through the arc-shaped mounting seats and fixedly mounted. The monitoring angle of the optical measurement components can be adjusted to ensure comprehensive monitoring of material tension.

[0017] The beneficial effects of this invention are:

[0018] (1) By integrating a rotating side guide roller group, a top-mounted transverse cutting component, an electrically controlled translational guide device, an optical measurement component, and an electrically controlled stacking device, this invention realizes the integrated operation of flexible material cutting, synchronous material guiding, automatic stacking, and unloading, and solves the problems of low functional integration and excessive manual intervention required by existing devices.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] Figure 1 , Figure 2 , Figure 3 , Figure 4 ,picture, Figure 6 , Figure 7 The multi-layer stacked material synchronous cutting device shown includes a main frame 1. The main frame 1 has outwardly protruding lateral assembly shafts 8 on both sides of its upper end. A flipping bushing 9 is movably fitted on the lateral assembly shaft 8. Lateral assembly frames 10 are installed on both sides of the flipping bushing 9. A first electrically controlled guide roller 11 and a second electrically controlled guide roller 12 are movably installed at the ends of the lateral assembly frames 10. An angle adjusting support rod 13 for controlling the flipping of the lateral assembly frames 10 is provided on one side of the flipping bushing 9. The angle adjusting support rod 13 controls the flipping of the lateral assembly frames 10 by extension and retraction. The flipping angle is 0°-90°, forming a rotating lateral guide roller group 2, which is used to stably guide multi-layer flexible materials into the interior of the main frame 1.

[0034] The main frame 1 has a forward-protruding horizontal assembly plate 14 fixedly mounted inside. A horizontal guide rail 3 is fixedly mounted on the lower surface of the horizontal assembly plate 14. Two independently controlled electric control screws 15 are installed inside the horizontal guide rail 3. A first horizontal assembly frame 16 is threaded onto the inner electric control screw 15, and a second horizontal assembly frame 19 is threaded onto the outer electric control screw. The first horizontal assembly frame 16 forms the installation base for the top-mounted horizontal cutting assembly 4, and the second horizontal assembly frame 19 forms the installation base for the electrically controlled translational material guiding device 5. Longitudinal side guide rails 21 are provided on the upper end of one side and the lower end of the other side of the first horizontal assembly frame 16. An electromagnet 22 and an iron spring 23 are installed inside the longitudinal side guide rail 21. A lateral extrusion block 24 is connected to one side of the electromagnet 22. A horizontal blade 25 is installed at the end of the lateral extrusion block 24, forming an upper magnetic control cutting blade 17 and a lower magnetic control cutting blade 18, realizing precise cutting in both directions. The second horizontal assembly frame 19 has magnetically controlled clamping modules 20 installed on both sides inside, which are used to clamp the material and pull it laterally to ensure the flatness of the material.

[0035] This device achieves fully automatic control of cutting size through electronic displacement, optical positioning, and servo closed-loop coordination: the target cutting length, width, number of cuts, and other parameters are input into the human-machine interface, and the system converts them into the stroke of the electronic control screw and the start and stop positions of the cutting components.

[0036] The electric control screw inside the horizontal guide rail 3 is driven by a servo motor and, in conjunction with an encoder, provides real-time feedback of displacement pulses to precisely control the horizontal start and stop position and travel distance of the top-mounted horizontal cutting component 4, achieving fixed length / fixed width positioning.

[0037] The optical measurement component synchronously monitors the edge position and lateral offset of the material. If the offset exceeds the tolerance, the system immediately corrects the clamping position and pulling force of the translation guide device 5 to ensure that the cutting edge line is consistent with the set size.

[0038] When the component reaches the set coordinate, the electromagnet 22 is energized to drive the horizontal blade 25 to quickly cut in both directions; after the cutting is completed, the spring returns to its original position, and the lead screw drives the component back to its original position, waiting for the next round of cutting. The entire process does not require manual alignment or manual control of the ruler.

[0039] Several inverted L-shaped internal supports 32 are fixedly mounted on the lower surface of the horizontal assembly plate 14. Arc-shaped adjustment seats 33 are fixedly mounted on the inner side of the internal supports 32. The optical measurement component 6 is inserted into the arc-shaped adjustment seat 33 through the arc-shaped mounting seat 34 and fixedly mounted. The angle can be adjusted along the arc-shaped adjustment seat 33. The optical measurement component 6 adopts the existing laser displacement optical probe. It emits an infrared laser beam to irradiate the surface of the material and receives the optical signal reflected by the material. It collects the sag, deformation amplitude and lateral displacement data of the material in real time, converts the physical signal into an electrical signal and transmits it to the central control system of the device to complete the real-time monitoring of the material tension.

[0040] During operation, the laser head emits a directional laser beam that illuminates the material surface. After reflection, the beam is received by the CCD / CMOS array inside the probe. Based on the position of the laser spot imaging, the real-time sag, lateral offset, and distance changes of the material are calculated, and the physical signals are converted into electrical signals and uploaded to the central control system. The system compares the signal with a preset tension threshold and adjusts it in real-time in a closed loop: if the material is too loose and the sag is too large, the guide roller speed is increased and the clamping force is increased to flatten the material; if the material is too tight and the deformation exceeds the limit, the guide roller speed is reduced and the clamping module is slightly retracted to release the tension. Through optical positioning and real-time feedback, the system ensures that the material is always in the optimal cutting posture—flat, without offset, and without wrinkles—providing positioning assurance for precise cutting.

[0041] An embedded lifting guide rail 26 is fixedly mounted on the lower front of the main frame 1. An electrically controlled lifting screw 27 is movably mounted inside the embedded lifting guide rail 26. An internally threaded lifting frame 28 is threaded onto the electrically controlled lifting screw 27. An upper extension seat 29 is slidably mounted on the upper end of the internally threaded lifting frame 28. An inner translation support rod 30 is fixed on the inner side of the internally threaded lifting frame 28. An embedded pressure detection plate 31 is mounted on the upper surface of the upper extension seat 29, which constitutes an electrically controlled stacking device 7 for receiving cut materials and automatically stacking them.

[0042] The working principle and process of this device are as follows: Before operation, depending on the running mode of the flexible material, top guiding or bottom cutting can be selected. The rotation angle of the side assembly frame 10 is adjusted (0°-90°) by the angle adjustment support rod 13. The material passes between the first electrically controlled guide roller 11 and the second electrically controlled guide roller 12. The material is adjusted by the forward and reverse rolling of the first electrically controlled guide roller 11 and the second electrically controlled guide roller 12. The monitoring angle of the optical measurement component 6 is adjusted by the arc-shaped adjustment seat 33 to ensure that the laser beam is vertically or obliquely aligned with the material conveying section, fully covering the material monitoring area and accurately collecting the material tension status data. The initial height of the electrically controlled stacking device 7 is adjusted so that the upper extension seat 29 corresponds to the cutting position.

[0043] During operation, flexible material is fed into the rotating lateral guide roller group 2. The first electrically controlled guide roller 11 and the second electrically controlled guide roller 12 rotate, smoothly guiding the material into the main frame 1. After the material enters, it is output downwards. The magnetic clamping module 20 of the electrically controlled translational guide device 5 is energized to clamp both sides of the material. The electrically controlled lead screw 15 drives the second transverse assembly frame 19 to move laterally, pulling the material laterally to a flat state. During this process, the optical measurement component 6 continuously emits lasers to monitor the material. When the material tension is detected to be too high (the material is taut and the sag is close to zero), the control is activated. The system immediately reduces the conveying speed of the first electrically controlled guide roller 11 and the second electrically controlled guide roller 12, while controlling the magnetically controlled clamping module 20 to slightly retract, reducing the lateral pulling force and quickly releasing the material tension. When it detects that the material tension is too low (material is too loose, sag is too large, or wrinkles appear), the system increases the speed of the guide rollers and increases the clamping force and lateral pulling stroke of the magnetically controlled clamping module 20 to quickly flatten the material. Through the linkage of optical monitoring and closed-loop electronic control adjustment, the material tension is always maintained within the preset reasonable range to avoid material deviation and wrinkles.

[0044] After the material is leveled, the electric control screw 15 drives the first horizontal assembly frame 16 to move to the cutting position. The electromagnet 22 inside the longitudinal side guide rail 21 is energized, pushing the lateral extrusion block 24 to extend and retract the horizontal blade 25. The upper magnetic control cutting blade 17 and the lower magnetic control cutting blade 18 cut the material in both directions. After the cutting is completed, the electromagnet 22 is de-energized, and the iron spring 23 drives the cutting blade to reset. The cut material falls onto the upper extension seat 29 of the electric control stacking device 7, and then the height is automatically adjusted according to gravity to achieve the effect of stacking the cut material. When the stacked material reaches the preset maximum height, the pressure threshold is measured by the embedded pressure detection plate 31. At this time, the inner translation support rod 30 pushes the upper extension seat 29 to move outward, making it easier for people to pick up and improving the safety of operation.

[0045] This application allows for feeding from one side or both sides simultaneously, and can be freely adjusted according to production efficiency requirements.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
