Its purpose is to perform longitudinal shearing of metal strips and rewind the slit strips into coils. It is easy to operate, has high cutting quality, high material utilization, and stepless speed regulation.

[0003] For example, in the prior art patent application with patent number CN218802480U, the front two sides of the fabric are placed on two hydraulic columns in the same group, and the middle and rear sections of the fabric are placed on two other hydraulic columns in the same group. At this time, the control panel is activated to control the hydraulic columns to clamp and start the conveyor belt to keep the fabric under tension. As the conveyor belt moves, the fabric is brought to the cutting point for cutting. After the cutting is completed, another set of hydraulic columns will rotate to the top of the worktable and repeat the above operation for the next round of cutting.

[0004] However, since it clamps the fabric during cutting, it is difficult to ensure that the longitudinal tension of the fabric remains stable. At the same time, it cannot quickly adjust the spacing between the blades as needed, which reduces work efficiency. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology uses clamping to compress the fabric during cutting, it is difficult to ensure that the longitudinal tension of the fabric remains stable, and it is also impossible to quickly adjust the spacing between the cutters as needed, which reduces work efficiency.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0022] Please see Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a multifunctional bonding and slitting machine for precise cutting of composite materials, including: Workbench 1; also includes: The lifting structure 4, adjusting structure 6, pressing structure 7, and cutting laser blade 8 are fixedly installed at the bottom of the worktable 1, the adjusting structure 6 is fixedly installed at the top of the lifting structure 4 and located at the top of the worktable 1, the pressing structure 7 is fixedly installed on both sides of the adjusting structure 6, and the cutting laser blade 8 is fixedly installed on both sides of the bottom of the adjusting structure 6.

[0023] For example, the lifting structure 4 includes a first telescopic rod 41, a connecting frame 42 is fixedly installed at the bottom of the first telescopic rod 41, and connecting arms 43 are fixedly connected to both sides of the top of the connecting frame 42.

[0024] Furthermore, the fixed frame 61 is a rectangular carbon steel welded frame with a length matching the width of the worktable 1. A through-flow groove 62 is provided inside along the length direction. The inner wall of the groove is coated with a polytetrafluoroethylene wear-resistant coating to reduce the sliding resistance of the slider. The slider 63 is a T-shaped slider that is adapted to the through-flow groove 62. The surface is also coated with a wear-resistant coating. The two sets of sliders 3 are respectively embedded on both sides of the through-flow groove 62. The bottom is reserved with bolt holes for installing the cutting laser knife 8, and the top is welded with a rotating shaft seat.

[0025] For example, the adjustment structure 6 includes a fixed frame 61, the inside of which is provided with a connecting groove 62, and sliders 63 are slidably connected to both sides inside the connecting groove 62. A second telescopic rod 65 is fixedly installed on the top of the fixed frame 61, and connecting rods 64 are rotatably connected to both sides of the output end of the second telescopic rod 65. The bottom of the connecting rod 64 is rotatably connected to the top of the slider 63.

[0026] Furthermore, the second telescopic rod 65 is a high-precision electric telescopic rod, which is fixedly installed at the top center of the fixed frame 61. The output end is welded with a cross-shaped connecting seat. The connecting rod 64 is a stainless steel connecting rod, with a total of 2 sets. Both ends are rotatably connected to the connecting seat of the second telescopic rod 65 and the rotating shaft seat of the slider 63 through bearings, forming a symmetrical transmission structure to ensure that when the second telescopic rod moves, the two sets of sliders slide synchronously towards or in opposite directions.

[0027] For example, the pressing structure 7 includes a mounting bracket 71. The mounting bracket 71 has fixing holes 72 on both the front and back sides. A pressing rod 73 is provided inside the fixing hole 72. A spring 75 is provided on the surface of the pressing rod 73 and at the bottom of the fixing hole 72. A pressing wheel 74 is fixedly installed at the bottom of the pressing rod 73.

[0028] Furthermore, the mounting bracket 71 is a U-shaped carbon steel frame, which is fixed to the outer wall of the fixing bracket 61 by welding on the inner side. The outer wall has two sets of fixing holes 72, one above the other. The pressing rod 73 is a stainless steel round rod that is inserted into the fixing hole 72. A limiting block is welded to the top to prevent it from falling off, and a wheel axle seat is welded to the bottom.

[0029] In use, the composite material roll to be cut is mounted on the spool of the left placement device 3. The free end of the roll is pulled out and passed sequentially above the left rotating auxiliary wheel of the cutting table 5, below the pressing wheel 74 of the pressing structure 7, and above the right rotating auxiliary wheel of the cutting table 5, finally fixed on the spool of the right winding device 2. The initial tension value is preset by the tension sensor of the winding device 2 to ensure that the material is in a slightly taut state without wrinkles.

[0030] Spacing adjustment stage: According to the preset cutting width, the second telescopic rod 65 of the adjustment structure 6 is activated. If the cutting width needs to be reduced, the output end of the second telescopic rod 65 extends and pushes the top connecting seat down. The two sets of connecting rods 64 transmit the thrust to both sides, causing the slider 63 to slide towards each other in the connecting groove 62 until the spacing between the two cutting laser blades 8 reaches the preset value. If the cutting width needs to be increased, the output end of the second telescopic rod 65 retracts, pulling the connecting seat upward. This causes the slider 63 to slide in the opposite direction via the connecting rod 64, completing the spacing adjustment. The entire adjustment process is electrically driven, ensuring precise positioning and requiring no manual intervention.

[0031] Height and Press Adjustment Phase: The first telescopic rod 41 of the lifting structure 4 is activated. When the first telescopic rod 41 retracts, it drives the adjustment structure 6 to descend as a whole through the connecting frame 42 and connecting arm 43. During the descent, the pressing wheel 74 first contacts the surface of the composite material. As the adjustment structure 6 continues to descend, the spring 75 is compressed, generating elastic pressure. The pressing wheel 74 forms a uniform elastic pressing on the material, and the pressure can be finely adjusted by the lifting height. When the bottom of the cutting laser knife 8 reaches the preset cutting height from the surface of the composite material, the first telescopic rod 41 stops moving, completing the height positioning.

[0032] In summary, by adopting an elastic pressing design: the continuous elastic pressure provided by the spring 75, combined with the rotatable pressing wheel 74, not only ensures the stability of the longitudinal tension of the material, but also avoids material damage or conveying jams caused by rigid clamping, reducing the burr rate of the cutting edge, greatly improving the cutting accuracy, and at the same time, it is convenient, efficient and versatile. Example

[0033] Please see Figure 5 This is the second embodiment of the present utility model.

[0034] For example, a cutting table 5 is fixedly installed on the top of the workbench 1, and rotating auxiliary wheels are provided on both sides of the cutting table 5.

[0035] Furthermore, spring 75: a cylindrical helical compression spring is selected and sleeved on the surface of the pressing rod 73, with its two ends abutting the bottom of the fixing hole of the mounting bracket 71 and the top of the pressing wheel 74 respectively, to provide elastic pressure.

[0036] For example, a winding device 2 is provided on the right side of the workbench 1 via a bracket, and a placement device 3 is provided on the left side of the workbench 1 via a fixed bracket.

[0037] Furthermore, the pressing wheel 74 is made of silicone and is mounted on the wheel axle seat at the bottom of the pressing rod 73 via a bearing. It can rotate flexibly and avoids sliding friction with the material.

[0038] For example, the top of the cutting laser blade 8 is fixedly mounted to the bottom of the slider 63 by bolts, and the inner side of the mounting bracket 71 is fixedly connected to the outer side of the fixing bracket 61.

[0039] Furthermore, the cutting laser blade 8 is a high-precision fiber laser blade. The top is detachably fixed to the bottom of the slider 63 by four hexagonal bolts. The laser emission direction is vertically downward and precisely aligned with the shallow groove of the cutting table 5. The laser blade is equipped with a cooling system to prevent the temperature from getting too high during long-term operation, which would affect the cutting accuracy. It also supports stepless power adjustment to adapt to the cutting of composite materials of different thicknesses.

[0040] During use, in the cutting and winding stages: the damping adjustment components of the cutting laser knife 8, the winding device 2, and the placement device 3 are activated simultaneously. The variable frequency motor of the winding device 2 drives the winding shaft to rotate, and pulls the composite material to the right at a preset speed. The rotating auxiliary wheel rotates synchronously with the material conveying to reduce the friction between the material and the cutting table 5. The cutting laser blade 8 emits a laser at a preset power to precisely cut the composite material that passes by at a constant speed. The laser energy is concentrated in the shallow groove of the cutting table 5 to avoid damaging the table surface and to ensure that the cut edge is flat and burr-free. The pressing roller 74 rotates synchronously during the material conveying process. The elasticity of the spring 75 ensures that the pressing roller 74 is always in contact with the material, compensating for slight fluctuations during the material conveying process in real time and maintaining stable longitudinal tension. The cut narrow strips of material are simultaneously wound up by the winding device 2. The tension sensor monitors the winding tension in real time and dynamically adjusts the motor speed to ensure that the winding is tight and not loose.

[0041] Stop and reset phase: After the composite material is cut, the sensor of the winding device 2 detects the end of the material and shuts down the cutting laser knife 8, the winding device 2 and the placement device 3 in sequence. Then the first telescopic rod 41 of the lifting structure 4 extends, driving the adjustment structure 6 to rise and reset. The pressing wheel 74 is removed from the material surface, completing one cutting operation.

[0042] In summary, the cutting height can be flexibly adjusted by the lifting structure 4, and with the stepless adjustment of the laser power, it can be adapted to various composite materials of different thicknesses, with a wide range of applications, while also being energy-saving and safe.
