Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a material support structure and a roller laser cutting machine. Background Technology

[0002] Laser cutting machines for rollers and support structures are primarily used in laser cutting of roller-type workpieces. In many industries, such as machinery manufacturing, automotive parts processing, and electronic equipment manufacturing, precise cutting of rollers is often required to meet the production needs of different products. Laser cutting machines for rollers provide stable support and precise positioning, and utilize laser cutting technology to achieve efficient and high-precision cutting, thereby improving product quality and production efficiency. Currently, laser cutting machines for rollers and support structures typically require the following technologies in practical applications:

[0003] 1. Precise displacement control technology is used to accurately adjust the position of the material support structure to adapt to the support requirements of rollers of different sizes, ensuring the stability of the rollers during the cutting process.

[0004] 2. Reliable limiting and centering technology ensures that the roller can be accurately centered before cutting, avoiding cutting deviation and improving cutting accuracy.

[0005] 3. High-efficiency laser cutting technology, including high-power laser generators and precise laser focusing systems, to achieve rapid and high-quality cutting of roller materials.

[0006] 4. Stable mechanical structure design technology ensures that the entire equipment can withstand the impact and vibration generated by laser cutting during operation, guaranteeing the stability and reliability of the cutting process.

[0007] Currently, various equipment and methods are used to achieve laser cutting of rollers. Some equipment employs a simple manual material support structure, where the roller is manually placed on a fixed support base, and then cut using a laser cutting head. This method is easy to operate, but it has poor adaptability to rollers of different sizes and makes it difficult to guarantee cutting accuracy. Other equipment uses a semi-automatic material support structure, with a motor-driven lead screw adjusting the material support position. However, its centering and limiting functions are relatively weak, and the roller is prone to shaking during cutting, affecting the cutting quality. Furthermore, while some high-end equipment has automated material support and cutting functions, its complex structure, high cost, and difficult maintenance make it unaffordable for small and medium-sized enterprises.

[0008] However, the above method has some prominent problems. When using existing laser cutting equipment, there is usually no limiting function for the two ends of the roller. It is only supported by the material support structure. When laser cutting is performed, the laser beam is focused on the surface of the roller. The high energy released instantaneously melts or vaporizes the material. This process will generate a certain reaction force, causing the roller to vibrate. Without the limiting function at both ends, the stability of the roller on the material support structure is insufficient, and it is easy to shake, which will affect the neatness of the cut end face. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a material support structure and a roller laser cutting machine. It solves the problem that existing laser cutting devices typically lack limiting functions at both ends of the roller, relying solely on the material support structure for support. During laser cutting, the laser beam is focused on the roller surface, and the instantaneously released high energy melts or vaporizes the material. This process generates a certain reaction force, causing the roller to vibrate. Without limiting at both ends, the roller's stability on the material support structure is insufficient, easily causing wobbling, which affects the neatness of the cut end face.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A material support structure and a roller laser cutting machine include a rectangular mounting box. The rectangular mounting box contains a displacement mechanism for centering and limiting. The displacement mechanism includes a cross-shaped sliding frame and two rotating seats. The cross-shaped sliding frame is slidably connected inside the rectangular mounting box, and the two rotating seats are rotatably connected inside the rectangular mounting box. The cross-shaped sliding frame contains a linkage mechanism for synchronously pushing the two rotating seats to rotate. The linkage mechanism includes two arc-shaped connecting rods, both rotatably connected inside the cross-shaped sliding frame and respectively rotatably connected inside the two rotating seats. The cross-shaped sliding frame and the two rotating seats each contain a rotation mechanism for contact and limiting. The rotation mechanism includes three rubber rollers, each rotatably connected inside the cross-shaped sliding frame and the two rotating seats. A cutting machine body is fixedly connected to the outer surface of the rectangular mounting box. A cylinder is fixedly connected inside the cutting machine body and fixedly connected to the lower end of the cross-shaped sliding frame.

[0012] Preferably, both of the rotating seats have a round rod shaft fitted inside.

[0013] Preferably, the rectangular mounting box has two U-shaped sliding seats slidably connected inside, and each of the two U-shaped sliding seats is rotatably connected to a roller.

[0014] Preferably, the cutting machine body is internally connected to a bidirectional lead screw.

[0015] Preferably, the rectangular mounting box has two sliding grooves inside.

[0016] Preferably, a motor mounting bracket is fixedly connected to the upper end of the rectangular mounting box, and a drive motor is fixedly connected inside the motor mounting bracket.

[0017] Preferably, a cutting component mounting bracket is fixedly connected to the upper end of the rectangular mounting box.

[0018] Preferably, the cutting component mounting bracket is equipped with a laser cutter.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. During the sliding process of the cross-shaped sliding frame, it drives the two arc-shaped connecting rods inside to rotate. When the arc-shaped connecting rods rotate, they pull the rotating seat to rotate around the axis of the round rod. This can accommodate rollers of different sizes. During the roller limiting process, the rubber wheel contacts the roller surface, which not only allows the roller to rotate around its own axis for cutting, but also plays a role in buffering and stabilizing the contact during limiting. At the same time, through the cooperation of the two cross-shaped sliding frames and four rotating seats respectively set at both ends of the cylinder, the two ends of rollers of different sizes can be limited to ensure that the roller remains stable during laser cutting.

[0021] Second, when the bidirectional lead screw is turned, it can drive the two U-shaped sliding seats to slide in opposite directions (sliding towards or away from each other at the same time, while keeping the center point unchanged), so as to adapt to the different positions where the rollers are centered and clamped by the cross-shaped sliding frame and the rotating seat at both ends, ensuring that the idler roller can always support the roller well.

[0028] This application provides a material support structure and a roller laser cutting machine, effectively solving the problem that existing laser cutting devices typically lack limiting functions at both ends of the roller. They rely solely on the material support structure for support. During laser cutting, the laser beam is focused on the roller surface, and the instantaneously released high energy melts or vaporizes the material. This process generates a certain reaction force, causing roller vibration. Without limiting at both ends, the roller's stability on the material support structure is insufficient, easily leading to wobbling and affecting the neatness of the cut end face. During the sliding of the cross-shaped sliding frame, it drives two internally rotating arc-shaped connecting rods. The rotation of these arc-shaped connecting rods pulls the rotating seat to rotate around the circular rod axis, adapting to rollers of different sizes. During roller limiting, the rubber roller contacts the roller surface, allowing the roller to rotate around its own axis for cutting, and also providing buffering and stabilizing contact during limiting. Simultaneously, the two cross-shaped sliding frames and four rotating seats respectively located at both ends of the cylinder can limit the ends of rollers of different sizes, ensuring the roller remains stable during laser cutting.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that existing laser cutting devices typically lack limiting functions at both ends of the roller, relying solely on a material support structure for support. During laser cutting, the laser beam is focused on the roller surface, and the instantaneously released high energy melts or vaporizes the material. This process generates a certain reaction force, causing roller vibration. The lack of limiting at both ends results in insufficient stability of the roller on the material support structure, easily causing wobbling and affecting the neatness of the cut end face. The overall concept is as follows: A material support structure and a roller laser cutting machine, including a rectangular mounting box 11, the rectangular mounting box 11 having an internal structure... The system includes a displacement mechanism for centering and limiting. This mechanism comprises a cross-shaped sliding frame 12 and two rotating seats 13. The cross-shaped sliding frame 12 is slidably connected inside a rectangular mounting box 11, and the two rotating seats 13 are rotatably connected inside the rectangular mounting box 11. The cross-shaped sliding frame 12 contains a linkage mechanism for synchronously pushing the two rotating seats 13 to rotate. This linkage mechanism includes two arc-shaped connecting rods 14, each rotatably connected inside the cross-shaped sliding frame 12 and respectively rotatably connected inside the two rotating seats 13. Both the cross-shaped sliding frame 12 and the two rotating seats 13 contain a rotating mechanism for contact and limiting. The rotating mechanism includes three rubber rollers 15, which are rotatably connected to the cross-shaped sliding frame 12 and two rotating seats 13. A cutting machine body 16 is fixedly connected to the outer surface of a rectangular mounting box 11. A cylinder 17 is fixedly connected inside the cutting machine body 16 and is fixedly connected to the lower end of the cross-shaped sliding frame 12. The cylinder 17 acts as a power source to push the cross-shaped sliding frame 12 to slide. During the sliding process, the cross-shaped sliding frame 12 drives two arc-shaped connecting rods 14 to rotate and open or close. The rotation of the arc-shaped connecting rods 14 pulls the two rotating seats 13, which are rotatably connected to them, to rotate. This rotation is achieved through the inward movement of the cross-shaped sliding frame 12. The sliding pull causes the two rotating seats 13 to rotate and retract (and simultaneously rotate towards the center of the cross-shaped sliding frame 12), thereby limiting the smaller size roller. When the cross-shaped sliding frame 12 slides outward, it pushes the two rotating seats 13 to rotate and open (i.e., simultaneously rotate away from the center of the cross-shaped sliding frame 12). The cross-shaped sliding frame 12 and the two rotating seats 13 contact the roller surface through the rotating rubber wheel 15 inside, allowing the roller to rotate for cutting. By using the two cross-shaped sliding frames 12 and four rotating seats 13 respectively set at both ends of the cylinder 17 to limit the ends of rollers of different sizes, stability is ensured during laser cutting.

[0031] Both rotating seats 13 have round rod shafts 18 fitted inside, and both round rod shafts 18 are rotatably connected inside rectangular mounting boxes 11. Two U-shaped sliding seats 19 are slidably connected inside the rectangular mounting boxes 11, and each U-shaped sliding seat 19 has a roller 21 rotatably connected inside. A bidirectional lead screw 22 is rotatably connected inside the cutting machine body 16, and the two U-shaped sliding seats 19 are threaded onto the outer surface of the bidirectional lead screw 22. Two sliding grooves 23 are formed inside the rectangular mounting boxes 11, and the two U-shaped sliding seats 19 are slidably connected inside the two sliding grooves 23 respectively. A motor mounting bracket 24 is fixedly connected to the upper end of the rectangular mounting boxes 11, and a drive motor 25 is fixedly connected inside the motor mounting bracket 24. The drive motor 25 is located inside the two rollers 21. The rotating seats 13 rotate around the round rod shafts 18, placing the rollers on the two rectangular mounting boxes 11. The upper end of the box 11 is clamped and limited. At this time, the roller is placed on the surface of two support rollers 21. The U-shaped sliding seat 19 and the support roller 21 are combined to form a material support structure. The two rotatable support rollers 21 are attached to the surface of the roller to support it. The output shaft of the drive motor 25 installed on the upper end of the rectangular mounting box 11 can drive one support roller 21 to rotate. At this time, the other support roller 21, which is away from the drive motor 25, plays a driven auxiliary role. The two rotating support rollers 21 drive the roller to rotate one revolution and complete the cutting work at a single point. By turning the bidirectional screw 22, the two U-shaped sliding seats 19 can be driven to slide in opposite directions, that is, slide in the direction of approaching or moving away at the same time. By turning the bidirectional screw 22, the two U-shaped sliding seats 19 can be driven to slide in opposite directions, and their center point remains unchanged to adapt to the cross-shaped sliding frame 12 and the rotating seat 13 clamped at both ends.

[0032] A cutting component mounting bracket 26 is fixedly connected to the upper end of the rectangular mounting box 11. A laser cutter 27 is installed inside the cutting component mounting bracket 26. The laser cutter 27 and the U-shaped sliding seat 19 are on the same vertical line. The laser cutter 27 is supported by the cutting component mounting bracket 26. The laser cutter 27 emits laser vertically downward to cut the roller.

[0033] To address the problems existing in the prior art, this utility model provides a material support structure and a roller laser cutting machine. During the sliding process of the cross-shaped sliding frame 12, it drives the two arc-shaped connecting rods 14 connected inside to rotate. When the arc-shaped connecting rods 14 rotate, they pull the rotating seat 13 to rotate around the circular rod shaft 18 as the axis, which can adapt to rollers of different sizes. During the roller limiting process, the rubber roller 15 contacts the roller surface, which not only allows the roller to rotate around its own axis for cutting, but also plays a role in buffering and stabilizing the contact during limiting. At the same time, by the cooperation of the two cross-shaped sliding frames 12 and four rotating seats 13 respectively set at both ends of the cylinder 17, the two ends of rollers of different sizes can be limited to ensure that the roller remains stable during laser cutting.

[0034] Rectangular mounting box 11: Serves as the basic frame of the entire device, providing installation space and support structure for the internal components;

[0035] Cross-shaped sliding frame 12: It is a key component of the displacement mechanism. Under the push of cylinder 17, it can slide inside the rectangular mounting box 11. Its sliding drives the arc-shaped connecting rod 14 connected to it to move, thereby controlling the rotation of the rotating seat 13 through the arc-shaped connecting rod 14.

[0036] Rotating seat 13: Rotatably connected inside the rectangular mounting box 11, and rotates about the round rod shaft 18 as the axis;

[0037] Arc-shaped connecting rods 14 (two): As the main component of the linkage mechanism, their two ends are rotatably connected to the inside of the cross-shaped sliding frame 12 and the rotating seat 13 respectively; when the cross-shaped sliding frame 12 slides, it drives the arc-shaped connecting rods 14 to rotate. Utilizing its own arc-shaped structural characteristics, the linear motion of the cross-shaped sliding frame 12 is converted into the rotational motion of the rotating seat 13, thereby realizing the synchronous rotation of the two rotating seats 13.

[0038] Rubber rollers 15: As a key component of the rotating mechanism, they are in direct contact with the roller surface. On the one hand, they enable the roller to rotate freely around its own axis when it is constrained, meeting the requirement that the roller completes a single-point cut in one rotation during laser cutting. On the other hand, the rubber material has a certain elasticity, which plays a buffering role during the constraining process, reducing the damage that may be caused to the roller surface by the constraining action. At the same time, it increases the friction with the roller surface and improves the stability of the constraining. It is an important component to ensure the stable rotation of the roller and reduce surface damage. Usually, the rollers to be cut are relatively long. Therefore, the clamping and contact points at both ends are far away from the cutting point and will not affect the integrity of the rubber rollers 15 due to the heat on the material surface.

[0039] The main body 16 of the cutting machine: As the core load-bearing part of the entire equipment, it is fixedly connected to the rectangular mounting box 11, providing the installation foundation for the entire material support structure;

[0040] Cylinder 17: Fixed inside the main body 16 of the cutting machine and connected to the lower end of the cross-shaped sliding frame 12, serving as the power source of the displacement mechanism and providing power for the sliding of the cross-shaped sliding frame 12;

[0041] Round rod shaft 18: It is respectively sleeved inside the two rotating seats 13 and rotatably connected inside the rectangular mounting box 11, providing a rotation axis for the rotating seats 13, ensuring that the rotating seats 13 can rotate stably and accurately around the arc-shaped connecting rod 14 under its pull;

[0042] U-shaped sliding seat 19: slides in the groove 23 inside the rectangular mounting box 11, and is rotatably connected to the roller 21 inside, together with the roller 21 forming a material support structure;

[0043] Idler roller 21: Rotatably connected inside the U-shaped sliding seat 19, together with the U-shaped sliding seat 19 forming a material support structure, and conforming to the surface of the roller to support it; one idler roller 21 is driven to rotate by the drive motor 25, and the other is a driven auxiliary. The two idler rollers 21 work together to drive the roller to rotate one revolution, realizing single-point cutting.

[0044] The bidirectional lead screw 22 is rotatably connected inside the main body 16 of the cutting machine, and two U-shaped sliding seats 19 are threadedly connected to its outer surface. When the bidirectional lead screw 22 is screwed, the rotation of the lead screw is converted into the linear motion of the U-shaped sliding seats 19, which drives the two U-shaped sliding seats 19 to slide in opposite directions. This allows the distance between the two support rollers 21 to be adjusted according to the roller size, thereby adapting to different positions where the rollers are centered and clamped by the cross-shaped sliding frame 12 and the rotating seat 13 at both ends. This ensures that the support rollers 21 can always support the rollers well, and is a key transmission component for realizing the adaptive adjustment of the material support structure.

[0045] Slide groove 23: Provides sliding guidance for U-shaped slide seat 19, restricts the movement trajectory of U-shaped slide seat 19, and makes it slide in opposite directions only along the direction of slide groove 23;

[0046] Motor mounting bracket 24: fixed to the upper end of rectangular mounting box 11, providing a mounting position for drive motor 25;

[0047] Drive motor 25: Installed inside the motor mounting bracket 24 and located inside the two idler rollers 21, its output shaft drives one of the idler rollers 21 to rotate, providing power for the rotation of the rollers;

[0048] Cutting component mounting bracket 26: fixed to the upper end of rectangular mounting box 11, providing support for laser cutter 27 and ensuring that laser cutter 27 maintains a stable position and posture during operation;

[0049] Laser cutter 27: The high-energy laser beam emitted by the laser cutter 27 acts on the surface of the roller, causing the roller material to melt or vaporize instantly, thereby realizing the cutting process of the roller. It is the core execution component for realizing the roller cutting function.

[0050] Working principle:

[0051] The first step involves placing the roller on top of two rectangular mounting boxes 11. At this point, the roller is positioned on the surface of the rotatable support roller 21 connected inside two U-shaped sliding seats 19. The U-shaped sliding seats 19 and the support roller 21 together form a material support structure. The roller is supported by two rotatable support rollers 21 against its surface. A drive motor 25, installed in the motor mounting bracket 24 at the top of the rectangular mounting box 11, drives one support roller 21 to rotate, while the other support roller 21 acts as a driven auxiliary. In this way, the two rotating support rollers 21 can drive the roller to rotate one revolution, thus completing the cutting work at a single point. A bidirectional lead screw 22 is rotatably connected inside the cutting machine body 16, and the two U-shaped sliding seats 19 are threadedly connected to the outer surface of the bidirectional lead screw 22, respectively... The rectangular mounting box 11 slides within two grooves 23. When the bidirectional lead screw 22 is turned, it drives the two U-shaped sliding seats 19 to slide in opposite directions (sliding towards or away from each other while keeping the center point unchanged). This adapts to the different positions where the roller is centered and clamped by the cross-shaped sliding frame 12 and the rotating seat 13 at both ends, ensuring that the roller 21 can always support the roller well. The cutting component mounting frame 26 at the upper end of the rectangular mounting box 11 supports the laser cutter 27, and the laser cutter 27 and the U-shaped sliding seats 19 are on the same vertical line. When the roller is limited, supported and rotated, the laser cutter 27 emits a laser vertically downward to cut the roller, thereby completing the processing of the roller.

[0052] In the second step, cylinder 17, acting as a power source, is fixed inside the cutting machine body 16 and connected to the lower end of the cross-shaped sliding frame 12. When cylinder 17 is activated, it pushes the cross-shaped sliding frame 12 to slide inside the rectangular mounting box 11. During the sliding process, the cross-shaped sliding frame 12 drives the two arc-shaped connecting rods 14 rotatably connected inside it. Since the arc-shaped connecting rods 14 are rotatably connected to the two rotating seats 13 respectively, when the arc-shaped connecting rods 14 rotate, they pull the rotating seats 13 to rotate around the circular rod shaft 18. When the cross-shaped sliding frame 12 slides inward (in the upward sliding direction), the two arc-shaped connecting rods 14 retract, pulling the two rotating seats 13 to rotate simultaneously towards the center of the cross-shaped sliding frame 12, thus limiting the movement of the smaller roller. When the cross-shaped sliding frame 12 slides outward (downward sliding direction), the two arc-shaped connecting rods 14 open, pushing the two rotating seats 13 to rotate simultaneously away from the center of the cross-shaped sliding frame 12, which can accommodate larger rollers. The cross-shaped sliding frame 12 and the two rotating seats 13 are each equipped with three rubber rollers 15. During the roller limiting process, the rubber rollers 15 contact the roller surface, which not only allows the roller to rotate around its own axis for cutting, but also plays a role in buffering and stabilizing the contact during limiting. At the same time, by cooperating with the two cross-shaped sliding frames 12 and four rotating seats 13 respectively set at both ends of the cylinder 17, the two ends of rollers of different sizes can be limited to ensure that the roller remains stable during laser cutting.

[0053] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
