Description

Technical Field

[0001] This utility model belongs to the field of wind turbine blade processing, specifically a diamond-shaped mesh shallow groove intelligent processing equipment for producing wind turbine blade core materials. Background Technology

[0002] Wind turbine blades are key components of wind turbine generators. Their main body typically employs a sandwich structure made of composite materials to balance structural strength and lightweight requirements. This sandwich structure consists of two layers of high-strength fiber skins bonded together with a lightweight foam core (such as PVC, PET, or balsa wood) via resin vacuum infusion. The skins primarily bear bending loads, the core separates the two skin layers, increases the moment of inertia of the blade cross-section, thus providing significant bending stiffness, and the resin acts as a bonding matrix, impregnating the fiber skins and filling the pores of the core. After curing, the three are firmly bonded together as a whole, achieving effective load transfer.

[0003] To improve the resin's wetting effect on the core material during infusion and the interfacial peel strength between the skin and core material after curing, while controlling the resin dosage, shallow grooves are typically machined on the core material surface to create flow channels. Currently, most core material processing equipment used in the industry produces straight or cross-shaped shallow grooves, the structure of which can be found in [reference needed]. Figure 1 , Figure 2 These two types of grooves have the following disadvantages: A single-line shallow channel has a simple channel structure and a single direction. During resin pouring, the channel lacks an effective lateral flow guiding structure, which easily leads to the resin flowing rapidly in a single direction. Areas far from the channel may not be fully poured, affecting the consistency of product quality.

[0004] Cross-shaped shallow grooves offer bidirectional airflow guidance, overcoming the shortcomings of straight shallow grooves. However, the intersections of the groove lines are all right angles. On one hand, excessive resin concentration at these right angles after injection can lead to a sharp-angle effect. When external forces are transmitted to these sharp angles, they cannot be smoothly dispersed, resulting in stress concentration. Furthermore, as the resin hardens and becomes more brittle after curing, these sharp angles easily become the starting point for crack initiation, threatening the structural safety and fatigue life of the wind turbine blades. On the other hand, right-angle intersections can easily form resin retention zones, increasing the resin's residence time in these areas and leading to excessive resin absorption (resin absorption rate). This not only increases the cost of expensive resin materials but also increases the weight of the wind turbine blades, causing the finished blades to exceed weight limits and affecting their aerodynamic performance and power generation efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to provide an intelligent processing equipment for producing wind turbine blade core materials with shallow diamond-shaped mesh grooves, thereby eliminating stress concentration, optimizing resin flow, and reducing the amount of adhesive absorbed by the core material.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A smart processing device for producing diamond-shaped shallow grooves for wind turbine blade core materials includes a platform, which is divided into a feeding area, a grooving area, and a discharging area along the core material conveying direction. The feeding area includes a first conveyor roller rotatably mounted on the platform; the grooving area includes a conveyor belt and a saw blade assembly rotatably mounted on the platform above the conveyor belt; and the discharging area includes a second conveyor roller rotatably mounted on the platform. The working surfaces of the first conveyor roller, the conveyor belt, and the second conveyor roller are at the same height. The device also includes a control box for controlling the transmission of the first conveyor roller, the conveyor belt, the second conveyor roller, and the saw blade assembly. The saw blade assembly includes components arranged sequentially along the core material conveying direction. The equipment includes a first saw blade spindle and a second saw blade spindle, which are parallel and rotatably mounted on the equipment platform. Multiple parallel first saw blades are spaced apart on the first saw blade spindle, with the disc surface of each first saw blade forming a first angle of inclination with the axis of the first saw blade spindle. Multiple parallel second saw blades are spaced apart on the second saw blade spindle, with the disc surface of each second saw blade forming a second angle of inclination with the axis of the second saw blade spindle. The first and second angles are equal in value, and the first and second saw blades are tilted in opposite directions. On a horizontal projection plane, the cutting trajectories of the first and second saw blades intersect to form a rhomboid grid structure.

[0007] As a limitation of this utility model: the saw blade assembly also includes a third saw blade spindle rotatably mounted on the equipment platform, the first saw blade spindle is located between the third saw blade spindle and the second saw blade spindle, and multiple parallel third saw blades are installed at intervals on the third saw blade spindle. On the horizontal projection plane, the third saw blades are perpendicular to the third saw blade spindle.

[0008] As a further limitation of this utility model: a pressure roller is rotatably installed on the equipment platform at the upstream of the third saw blade spindle and the downstream of the second saw blade spindle, and a gap is formed between the pressure roller and the conveyor belt for the core material to pass through.

[0009] As a further limitation of this utility model: the interiors of the first saw blade spindle, the second saw blade spindle, and the third saw blade spindle are all hollow, and each of the first saw blade spindle, the second saw blade spindle, and the third saw blade spindle is provided with a number of air jet holes.

[0010] As a further limitation of this utility model: the equipment platform is provided with a cover for covering the pressure roller, the first saw blade spindle, the second saw blade spindle and the third saw blade spindle, and a dust suction pipe is provided on the cover. One end of the dust suction pipe extends into the cover and the other end is used to connect to the dust suction equipment.

[0011] As another limitation of this utility model: the feeding area is provided with a first lifting platform for placing core material, a first power component for driving the first lifting platform to lift, and a pushing mechanical arm assembly for pushing the core material into the first conveying roller; the output end of the first power component is connected to the input end of the first lifting platform, and the input end of the first power component and the control box, as well as the input end of the pushing mechanical arm assembly and the control box, are all signal connected.

[0012] As a further limitation of this utility model: the feeding area is also equipped with an infrared rangefinder for detecting the stacking height of the core material on the first lifting platform. The infrared rangefinder is fixedly installed directly above the first lifting platform. The signal output terminal of the infrared rangefinder is connected to the signal input terminal of the control box. The control box controls the first power component and the pushing robotic arm assembly to move according to the signal fed back by the infrared rangefinder.

[0013] As a further limitation of this utility model: the unloading area is provided with a transition platform and an unloading robotic arm that are connected to the second conveying roller. The transition platform is located on the discharge side of the second conveying roller, and the unloading robotic arm is suspended directly above the transition platform. The input end of the unloading robotic arm is connected to the control box for signal transmission.

[0014] As a further limitation of this utility model: the unloading area is also provided with a second lifting platform for placing the slotted core material and a second power component for driving the second lifting platform to rise and fall, and the input end of the second power component is connected to the control box signal.

[0015] As a further limitation of this utility model: the grooving area is provided with a drive mechanism that drives the first saw blade spindle, the second saw blade spindle, the third saw blade spindle and the pressure roller to rise and fall together. The input end of the drive mechanism is connected to the control box. The control box is configured to adjust the height of the first saw blade spindle, the second saw blade spindle, the third saw blade spindle and the pressure roller through the drive mechanism based on the core material thickness information measured by the infrared rangefinder.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: This invention improves upon existing core material processing equipment. The main improvement lies in the saw blade assembly, which includes a first saw blade spindle and a second saw blade spindle. The disc surface of the first saw blade on the first saw blade spindle is set at a first inclination angle to the axis of the first saw blade spindle; the disc surface of the second saw blade on the second saw blade spindle is set at a second inclination angle to the axis of the second saw blade spindle. The first and second inclination angles are equal in value and opposite in direction. On a horizontal projection plane, the cutting trajectories of the first and second saw blades intersect to form a rhomboid mesh structure. In practice, the first and second saw blades are used to groove the core material. The groove shape is a rhomboid mesh, and the angle at the intersection of the groove lines is 60° or 120°. When the resin passes through the intersection, it can disperse smoothly, which solves the problem of stress concentration caused by resin concentration at the right angle and avoids crack initiation. Furthermore, the smooth dispersion of resin can reduce the residence time of resin at the intersection, reduce the amount of resin absorbed by the core material, thereby reducing material costs. The weight of the wind turbine blade is also reduced, improving its aerodynamic performance and power generation efficiency.

[0017] In summary, this invention can eliminate stress concentration, improve resin flow at intersections, and reduce the amount of adhesive absorbed by the core material; this invention is applicable to all scenarios where diamond-shaped mesh grooves need to be created in the core material.

Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0022] The directional terms or positional relationships such as "left," "right," "front," and "back" used in the embodiments are based on the drawings in this utility model specification. Figure 6 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0023] like Figures 3 to 10As shown, this embodiment includes a device platform 1, which is divided into a loading area 2, a grooving area 3, and a unloading area 4 along the conveying direction of the core material 9 (i.e., from left to right). The loading area 2 includes multiple first conveying rollers 5 rotatably mounted on the device platform 1. These first conveying rollers 511 are parallel to each other and are driven by a single motor (not shown) via a sprocket. Their roller surfaces collectively form the conveying working surface of the core material 9. The grooving area 3 includes a conveyor belt 7 and a saw blade assembly rotatably mounted on the device platform 1 above the conveyor belt 7. The conveyor belt 7 receives the core material 9 from the loading area 2 and allows it to pass smoothly through the grooving area 3. The unloading area 4 includes multiple second conveying rollers 6 rotatably mounted on the device platform 1, driven in a similar manner to the first conveying rollers 5. The working surfaces of the first conveying rollers 5, the conveyor belt 7, and the second conveying rollers 6 are at the same height to ensure the core material 9 is conveyed smoothly. Here, the working surface refers to the roller surface of the first conveying roller 5, the belt surface of the conveyor belt 7, and the roller surface of the second conveying roller 6. It also includes a control box 8 for controlling the transmission of the first conveyor roller 5, the conveyor belt 7, and the second conveyor roller 6. The control box 8 integrates electrical control components such as a PLC, frequency converter, and human-machine interface. The control box 8 is electrically connected to the motors driving the first conveyor roller 5, the conveyor belt 7, and the second conveyor roller 6 via cables, and is used to coordinate and control their start / stop and speed, achieving automated continuous conveying of the core material 9. In implementation, the core material 9 is fed onto the first conveyor roller 5 and conveyed onto the conveyor belt 7. After being grooved by the saw blade group, it is unloaded by the second conveyor roller 6. This part is prior art.

[0024] The main improvement of this embodiment compared to the existing core material 9 processing equipment is as follows: I. Saw blade assembly; In this embodiment, as Figure 6 As shown, the saw blade assembly includes a first saw blade spindle 10 and a second saw blade spindle 11 arranged sequentially along the transport direction of the core material 9. The first saw blade spindle 10 and the second saw blade spindle 11 are each rotatably mounted on the equipment platform 1 via bearing seats (not shown in the figure). The first saw blade spindle 10 and the second saw blade spindle 11 are driven to rotate by independent servo motors (not shown in the figure), and the start, stop, and speed of the servo motors are precisely controlled by the control box 8.

[0025] like Figure 6 , 7 As shown, multiple parallel first saw blades 13 are installed at intervals on the first saw blade spindle 10, and the disc surface of the first saw blade 13 is set at a first inclination angle α with the axis of the first saw blade spindle 10.

[0026] Multiple parallel second saw blades 14 are also installed at intervals on the second saw blade spindle 11. The disc surface of the second saw blade 14 is set at a second inclination angle β with the axis of the second saw blade spindle 11.

[0027] The first tilt angle α and the second tilt angle β are equal in value, both being 30° in this embodiment, and the tilt directions of the first saw blade 13 and the second saw blade 14 are opposite, that is, as Figure 7 As shown, the first saw blade 13 is tilted to the right front, and the second saw blade 14 is tilted to the right rear. On the horizontal projection plane, the cutting paths of the first saw blade 13 and the second saw blade 14 intersect to form a diamond-shaped grid structure. (See Figure 14) Figure 10 .

[0028] As the core material 9 is carried by the conveyor belt 7 and passes sequentially beneath the rotating first saw blade spindle 10 and second saw blade spindle 11, the first saw blade 13 cuts a set of parallel oblique grooves on the surface of the core material 9. Subsequently, the second saw blade 14 cuts another set of oblique grooves in the opposite direction. On the horizontal projection plane, these two sets of oblique grooves intersect each other, naturally forming a continuous diamond-shaped grid-like shallow groove structure. The intersection angle of this diamond grid is 60° or 120°. Compared with the traditional 90° right-angle intersection, the resin can be smoothly dispersed when passing through the intersection point, avoiding stress concentration, thus significantly reducing the risk of cracks in the wind turbine blades at the groove intersection points during use. At the same time, this non-right-angle smooth structure also facilitates the flow and dispersion of resin during injection, reduces resin retention at corners, helps reduce the amount of resin absorbed by the core material 9, saves costs, and reduces blade weight.

[0029] Furthermore, such as Figure 6 , 7 As shown, the saw blade assembly also includes a third saw blade spindle 12 rotatably mounted on the equipment platform 1 via a bearing housing. The first saw blade spindle 10 is located between the third saw blade spindle 12 and the second saw blade spindle 11. Multiple parallel third saw blades 15 are spaced apart on the third saw blade spindle 12. See [reference needed] on the horizontal projection plane. Figure 6 The third saw blade 15 is perpendicular to the axis of the third saw blade spindle 12; in other words, the third saw blade 15 is mounted upright, not at an angle. During implementation, the core material 9 first passes through the third saw blade spindle 12. The rotating third saw blade 15 cuts a set of straight shallow grooves on its surface in the same direction as the feed. Subsequently, the core material 9 continues to advance, and is successively processed by the first saw blade 13 and the second saw blade 14 to create diamond-shaped mesh shallow grooves. On the horizontal projection plane, the straight grooves cut by the third saw blade 15 penetrate the diagonal of the diamond-shaped mesh shallow grooves, as shown... Figure 10 As shown, the straight grooves divide each rhombus grid into two triangles. The straight grooves provide a more direct and shorter flow path for resin injection. Together with the rhombus grids, they form an efficient three-dimensional flow guiding network, ensuring that the resin can quickly penetrate into all areas and avoid injection dead zones. This improves the wetting quality and further optimizes the amount of resin used.

[0030] This embodiment also adds a structure to ensure the flatness of the machining process. For example... Figure 6-8 As shown, on the equipment platform 1, a pressure roller 16 is rotatably mounted at positions upstream of the third saw blade spindle 12 (i.e., to the left of the third saw blade spindle 12) and downstream of the second saw blade spindle 11 (i.e., to the right of the second saw blade spindle 11). The pressure roller 16 is a solid steel roller with a smooth surface, forming a gap between the pressure roller 16 and the conveyor belt 7 for the core material 9 to pass through. In practice, before entering the third saw blade spindle 12 for grooving, the core material 9 passes under the pressure roller 16 on the left. The pressure roller 16 presses the core material 9 tightly against the conveyor belt 7, effectively preventing warping of the core material 9 itself or warping caused by the cutting force of the saw blade. Similarly, when the diamond groove is completed and the core material is about to leave the second saw blade spindle 11, the pressure roller 16 on the right flattens the core material 9 again. This structure ensures that the core material 9 remains flat and stable throughout the grooving process, thereby ensuring the consistency of depth and shape accuracy of the straight groove and the diamond groove. If the core material 9 warps up during cutting, it can cause uneven groove depth and even damage the saw blade and equipment.

[0031] The first saw blade spindle 10, the second saw blade spindle 11, and the third saw blade spindle 12 are all machined into hollow structures. During use, a high-pressure air source (such as an air compressor) is connected to one end of each of these spindles via a rotary joint. Figure 6 , 7 As shown, the first saw blade spindle 10, the second saw blade spindle 11, and the third saw blade spindle 12 are each equipped with several air jet holes 17. When the equipment is running, high-pressure gas is continuously introduced into the interior of the high-speed rotating first saw blade spindle 10, the second saw blade spindle 11, and the third saw blade spindle 12, and is ejected at high speed from each air jet hole 17. This design achieves two key functions: First, efficient cooling: The high-speed airflow blows directly onto the cutting contact area between the saw blade and the core material 9, which can quickly remove the heat generated by cutting, effectively preventing the saw blade from annealing or becoming dull due to overheating, significantly extending the service life of the saw blade, and ensuring the quality of the cut surface. Second, instant dust removal: Cutting the core material 9 will generate a large amount of fine dust. The high-speed airflow can instantly blow the newly generated dust from the saw blade gaps and cutting grooves, suspending it in the air and preventing dust from accumulating in the saw blade, spindle, or cutting groove, thus affecting the processing accuracy.

[0032] To improve this embodiment, such as Figure 3 , 5As shown, the equipment platform 1 is equipped with a cover 18 for covering the pressure roller 16, the first saw blade spindle 10, the second saw blade spindle 11, and the third saw blade spindle 12. Openings for the core material 9 to enter and exit are located at both the left and right ends of the cover 18. A dust extraction pipe 19 is installed on the top of the cover 18, with one end extending into the cover 18 and the other end connected to a dust extraction device. The cover 18 ensures operator safety, preventing accidental contact with the high-speed rotating saw blades and pressure roller 16 during equipment operation. It also continuously removes suspended dust blown up by the air jet 17, fundamentally solving the dust pollution problem of foam grooving, greatly improving the working environment, protecting employee health, and meeting environmental protection requirements.

[0033] II. Automatic feeding component; like Figure 3 , 4 As shown, the feeding area 2 is equipped with a first lifting platform 20 for placing the core material 9, a first power component 21 for driving the first lifting platform 20 to lift, and a pushing mechanical arm assembly for pushing the core material 9 into the first conveying roller 5.

[0034] The first power component 21 is a conventional hydraulic cylinder. The hydraulic cylinder controls the movement of the forks in the first lifting platform 20 to achieve the lifting and lowering of the first lifting platform 20. The structure and lifting method of the first power component 21 and the first lifting platform 20 are the same as those of the conventional scissor lift platform. The first lifting platform 20 is used to support stacks of multiple core materials to be processed.

[0035] The pushing robotic arm assembly includes a stand 22, a linear slide rail 23 fixed to the stand 22 and extending along the conveying direction of the core material 9, a slide block 24 driven by a hydraulic cylinder to move left and right on the linear slide rail 23, and a push plate 25 fixedly mounted on the slide block 24. The upper surface of the push plate 25 is in contact with the side surface of the core material 9. It should be noted that the hydraulic cylinder in the pushing robotic arm assembly is not shown in the figure.

[0036] The output end of the first power component 21 is connected to the input end of the first lifting platform 20. The input end of the first power component 21 is connected to the control box 8, the input end of the pushing robotic arm assembly (i.e., the input end of the hydraulic cylinder), and the control box 8.

[0037] In practice, after a stack of core materials 9 to be processed is placed on the first lifting platform 20, the layer number information is manually entered on the display screen of the control box 8, and the control box 8 can automatically complete the loading process. Specifically, the first power component 21 drives the first lifting platform 20 to rise, lifting the top layer of core materials 9 to a height level with the working surface of the first conveyor roller 5. Subsequently, the control box 8 instructs the pushing robotic arm assembly to move, and the slide 24 drives the push plate 25 to move to the right, smoothly pushing the top layer of single core material 9 onto the first conveyor roller 5, so that it enters the slotting area 3. After the pushing is completed, the push plate 25 returns to its original position, and the first lifting platform 20 rises again by the thickness of one plate, ready to push the next core material 9. The pushing robotic arm assembly replaces the traditional manual handling and pushing operations, reducing labor intensity and greatly improving the overall production efficiency.

[0038] Furthermore, the loading area 2 is also equipped with an infrared rangefinder 26 for detecting the stacking height of the core material 9 on the first lifting platform 20. The infrared rangefinder 26 is mounted on the upright frame 22. The infrared rangefinder 26 is fixedly installed directly above the first lifting platform 20, with its probe pointing vertically downwards. The signal output terminal of the infrared rangefinder 26 is connected to the signal input terminal of the control box 8, transmitting the measured distance data to the PLC in the control box 8 in real time. The control box 8 controls the first power component 21 and the pushing robotic arm assembly to move according to the signal fed back by the infrared rangefinder 26.

[0039] Working principle: During initialization, the infrared rangefinder 26 measures the distance to the unloaded surface of the first lifting platform 20, which is recorded as the reference value Z0. After the core material 9 is stacked on the first lifting platform 20, the infrared rangefinder 26 measures the distance Z to the upper surface of the stack of core material 9 in real time. The control box 8 calculates (Z0-Z) to obtain the total height of the current stack, and then, combined with the preset number of core material 9 layers, automatically calculates the accurate thickness of each core material 9. The control box 8 controls the lifting and lowering of the first lifting platform 20 to always maintain the upper surface of the top layer of core material 9 at a fixed target height (i.e., flush with the working surface of the first conveyor roller 5), ensuring that the pushing robotic arm assembly can accurately push the core material 9 into the first conveyor roller 5 each time. As the core material 9 is used one by one, the stack height decreases. When the distance value Z measured by the infrared rangefinder 26 returns to the initial reference value Z0, the control box 8 can determine that the core material 9 has been completely used up, and then automatically stop the operation of the pushing robotic arm assembly and the first lifting platform 20, thus realizing intelligent management.

[0040] III. Automatic feeding assembly; like Figure 3 , 5 As shown in Figures 9 and 1, the unloading area 4 is equipped with a transition platform 27 and an unloading robotic arm 28 that are connected to the second conveying roller 6.

[0041] The transition platform 27 is located on the discharge side of the second conveyor roller 6, and its working surface is flush with the roller surface of the second conveyor roller 6. Multiple unpowered, wide-spaced roller sets are installed on the transition platform 27, and the distance between two adjacent rollers 29 is significantly greater than the distance between two adjacent second conveyor rollers 6.

[0042] The unloading robotic arm 28 is suspended above the transition platform 27 via a rigid gantry 30. The input end of the unloading robotic arm 28 is connected to the control box 8, allowing it to move forward, backward, up, and down on the rigid gantry 30. The unloading robotic arm 28 is already implemented on current processing equipment and is considered prior art; its structure will not be detailed here. The drawing of the unloading robotic arm 28 in the figure is for illustrative purposes only. During implementation, the slotted core material 9 is fed out by the second conveyor roller 6 and slides onto the transition platform 27. At this time, the control box 8 commands the unloading robotic arm 28 to move. The unloading robotic arm 28 descends to the position of the core material 9, and the folding flap 281 folds inward (the folding flap 281 is located in the gap between two adjacent rollers 29), lifting the core material 9 from the bottom. Then, the unloading robotic arm 28 transfers the core material 9 to the designated stacking area.

[0043] To improve this embodiment, the unloading area 4 is further provided with a second lifting platform 31 for placing the slotted core material 9 and a second power component 32 for driving the second lifting platform 31 to rise and fall. The structure of the second lifting platform 31 is the same as that of the first lifting platform 20. The input terminal of the second power component 32 is connected to the control box 8 via a signal, and the structure of the second power component 32 is the same as that of the first power component 21.

[0044] The unloading robotic arm 28 moves the processed core material 9 to the top of the second lifting platform 31 and lowers it. The control box 8 records the number of stacked core materials 9. Each time a core material 9 is placed, the second power unit 32 drives the second lifting platform 31 to automatically descend by one plate thickness. Regardless of the number of stacked core materials 9, the top surface of the stack is always maintained at a fixed height that facilitates the unloading robotic arm 28 to place the materials. This achieves automated and neat stacking of finished core materials 9, eliminating the need for manual material stacking.

[0045] It should be further explained that the grooving area 3 is equipped with a drive mechanism that drives the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16 to move up and down together. Specifically, as shown... Figure 5 , 8As shown, a mounting frame 33 is slidably mounted on each end of the saw blade assembly on the equipment platform 1. The mounting frames 33 are connected to the equipment platform 1 via a slide rail assembly, allowing the mounting frames 33 to move up and down relative to the equipment platform 1. The ends of the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16 are all rotatably connected to the mounting frames 33 via bearing seats (not shown in the figure). The drive mechanism is a conventional hydraulic cylinder, and there are two drive mechanisms, both located at the bottom of the equipment platform 1. The output end of each drive mechanism is connected to a mounting frame 33, and the input end of the drive mechanism is connected to the control box 8 via a signal connection. The control box 8 is configured to adjust the height of the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16 through the drive mechanisms based on the core material 9 thickness information measured by the infrared rangefinder 26. For example, if the grooving depth is set to 2mm, then when the core material 9 is 20mm thick, the height of the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16 should be 18mm. When a new stack of core material 9 with a thickness of 22mm is placed, to ensure the grooving depth is 2mm, the height of the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16 needs to be raised to 20mm. This operation is achieved by the control box 8 receiving the precise thickness information of the currently feeding single core material 9, measured in real time by the infrared rangefinder 26, and then calculating and controlling the lifting and lowering of the drive mechanism to adjust the height of the mounting frame 33, thereby adjusting the height of the first saw blade spindle 10, the second saw blade spindle 11, the third saw blade spindle 12, and the pressure roller 16. The entire process requires no manual intervention or machine adjustment, ensuring absolute consistency in product quality.
