Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting device for embroidery machines. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby achieving the purpose of cutting the workpiece. Laser cutting is one of the thermal cutting methods.

[0003] Patent CN114101932B discloses a laser cutting device for embroidery machines, including a laser cutting unit, a cutting mounting frame, a water pipe assembly, and a smoke exhaust pipe assembly. The water pipe assembly and the laser cutting unit are respectively fixedly installed on the cutting mounting frame, and the water pipe assembly is connected to the laser cutting unit. In the actual assembly process, the structure of the cutting mounting frame is adjusted according to the model and size of the embroidery machine, and the length and assembly position of the light guide unit tube and the smoke exhaust unit tube in the laser cutting device are adjusted according to the installation environment to meet the installation requirements of different embroidery machines and improve the versatility of the laser cutting device. However, there is still a problem that the burrs remaining after cutting need to be manually polished, which is time-consuming and laborious. Therefore, a laser cutting device for embroidery machines is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a laser cutting device for embroidery machines, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a laser cutting device for an embroidery machine, comprising a welding chamber shell, a control block fixedly connected to the top of the welding chamber shell, an electric guide rail fixedly connected to the top of the welding chamber shell, a device frame slidably connected to the inner wall of the electric guide rail, a welding crossbeam provided inside the device frame, a welding head fixedly connected to the outer wall of the welding crossbeam, a rotating mechanism provided at the top of the welding chamber shell, a post-weld maintenance mechanism provided at the top of the welding chamber shell, and a slag collection rod provided inside the welding chamber shell.

[0006] The rotating mechanism includes a first spiral rod, a power box, a three-grip chuck, a device moving block, an inner slide rod, a grinding disc, and a transverse L-shaped rod. The first spiral rod is rotatably connected to the inner wall of the welding chamber shell. The power box is fixedly connected to the top of the welding chamber shell. The three-grip chuck is rotatably connected to the left side of the power box. The device moving block is movably connected to the outer circumferential surface of the first spiral rod. The inner slide rod is slidably connected to the inner wall of the device moving block. The grinding disc is fixedly connected to the outer wall of the device moving block. The transverse L-shaped rod is fixedly connected to the outer wall of the device moving block. The transverse L-shaped rod is slidably connected to the top inner wall of the welding chamber shell. A motor is installed on the left side of the first spiral rod.

[0007] The rotating mechanism further includes a lateral L-frame, a gripping rod, a lateral groove, a second helical rod, a limiting vertical rod, a vertical moving plate, and a fixed unloading plate. The lateral L-frame is fixedly connected to the outer wall of the device's moving block. The gripping rod is fixedly connected to the outer wall of the lateral L-frame. The lateral groove is opened on the right inner wall of the welding chamber. The lateral L-frame is slidably connected to the inner wall of the lateral groove. The second helical rod is rotatably connected to the top of the lateral L-frame. The limiting vertical rod is fixedly connected to the top of the lateral L-frame. The vertical moving plate is movably connected to the outer circumferential surface of the second helical rod. The vertical moving plate is slidably connected to the outer circumferential surface of the limiting vertical rod. The fixed unloading plate is fixedly connected to the outer wall of the vertical moving plate.

[0008] The rotating mechanism further includes a transmission block, a bidirectional screw, a fixed bottom semicircle, a top semicircle, a connecting telescopic rod, and a rotating shaft roller. The transmission block is movably connected to the circumferential surface of the screw. The bidirectional screw is rotatably connected to the inner wall of the transmission block. The fixed bottom semicircle is movably connected to the outer circumferential surface of the bidirectional screw. The connecting telescopic rod is fixedly connected to the top of the fixed bottom semicircle, and the top semicircle is fixedly connected to the top of the connecting telescopic rod. The rotating shaft roller is rotatably connected to the inner wall of the top semicircle, and the rotating shaft roller is rotatably connected to the fixed bottom semicircle. The device can cut tubular workpieces by manually rotating a bidirectional screw. During rotation, the bidirectional screw, through its bidirectional spiral grooves on the circumferential surface, causes the fixed bottom semicircles at both ends to converge towards the center. As the fixed bottom semicircles move towards the center, the top semicircle and the connecting telescopic rod also move towards the center, thus clamping one end of the tubular workpiece. Pulling the gripping rod moves the device's moving block along the circumferential surface of the screw, moving the grinding disc to the bottom of the circumferential surface of the workpiece to be cut. Then... The other end is clamped to the inner wall of the three-jaw chuck to complete the preliminary work before cutting the workpiece. Then, the second screw rod is manually rotated, and the spiral groove on the circumference of the second screw rod drives the vertical moving plate to move up or down under the limit of the vertical rod. During the movement of the vertical moving plate, the fixed unloading plate moves. During the movement of the fixed unloading plate, the pipe below is squeezed and limited, so that it is pressed down and the pipe is in close contact with the grinding plate. Then, the three-jaw chuck rotates and drives the pipe to be cut to rotate. During the rotation, the welding head starts to cut the tubular workpiece. During the cutting process, the three-jaw chuck rotates and drives the pipe to rotate. During the rotation and cutting process, the burrs generated on the edge of the pipe are ground by the grinding plate, avoiding the need for manual trimming of the pipe after cutting, thereby increasing work efficiency. At the same time, the motor is started to drive the first screw rod to rotate. During the rotation of the first screw rod, the transmission block moves under the limit of the welding chamber shell, thereby adjusting the distance between it and the power box to adapt to pipes of different lengths.

[0009] Preferably, the post-weld maintenance mechanism includes a shallow limiting groove, a transmission gear, a telescopic vertical plate, and a reciprocating screw. The shallow limiting groove is formed on the top outer wall of the welding chamber. The transmission gear is fixedly connected to the top outer wall of the welding chamber. One end of the telescopic vertical plate is fixedly connected to the bottom outer wall of the vertical plate, and the other end of the telescopic vertical plate is slidably connected to the inner wall of the shallow limiting groove. The reciprocating screw is rotatably connected to the inner wall of the telescopic vertical plate, and the reciprocating screw and the transmission gear are driven by gears.

[0010] The post-weld maintenance mechanism also includes a dust removal plate, a limiting block ball, and a vertical groove. The dust removal plate is movably connected to the outer circumferential surface of the reciprocating lead screw, the limiting block ball is fixedly connected to the left outer wall of the reciprocating lead screw, and the vertical groove is formed on the inner wall of the weld joint.

[0011] The post-weld maintenance mechanism also includes a sliding crossbar, a protective arc shell, and a retaining spring. The sliding crossbar is slidably connected to the inner wall of the welding head, the protective arc shell is fixedly connected to the outer wall of the sliding crossbar, and the retaining spring is fixedly connected to the outer wall of the welding head. The sliding crossbar and the retaining spring are connected by a spring. After the device has finished working, some debris and impurities will remain on the surface of the device. Then, pulling the gripping rod will move the vertical moving plate. During the movement of the vertical moving plate, the telescopic vertical plate at the bottom will move. During the movement of the telescopic vertical plate, the reciprocating screw will move. During the movement of the reciprocating screw, the gears and transmission gears mesh to drive the reciprocating screw... The rod rotates, and the reciprocating screw drives the slag removal blade to move back and forth under the limit of the welding chamber shell through the cross-shaped spiral grooves on the circumferential surface. During the movement, the slag removal blade pushes the welding slag adhering to the surface of the device into the gap of the shallow limiting groove, avoiding excessive accumulation of welding slag on the device, which would affect the welding efficiency. When the device moves downward during the welding process, the welding head contacts the surface of the workpiece, and the protective arc shell also contacts the pipe to be cut below it. After contacting the workpiece, the protective arc shell prevents the laser beam and sparks generated during the cutting process from flying everywhere, thus avoiding safety hazards in the workshop.

[0012] Preferably, the slag collection rod further includes a telescopic rod, a horizontal plate, and a dust sweeping brush. The telescopic rod is fixedly connected to the bottom of the vertical moving plate, the horizontal plate is fixedly connected to the bottom of the telescopic rod, and the dust sweeping brush is fixedly connected to the bottom of the horizontal plate.

[0013] The slag collection rod also includes an arc-shaped plate, a slag discharge door, and a connecting plate. The arc-shaped plate is fixedly connected to the bottom inner wall of the welding chamber shell, the slag discharge door is rotatably connected to the outer wall of the welding chamber shell, and the connecting plate is fixedly connected to the outer wall of the transverse L-frame.

[0014] The slag collection rod also includes a cold liquid chamber and an injection pipe. The cold liquid chamber is fixedly connected to the inner wall of the connecting plate, and the injection pipe is slidably connected to the top inner wall of the cold liquid chamber. Impurities on the device fall to the bottom of the device through the shallow limiting groove. Then, the vertical moving plate moves the telescopic rod, which in turn moves the horizontal plate at the bottom. The horizontal plate moves the dust sweeping brush, which pushes the impurities and dust on the top of the arc-shaped plate to the vicinity of the slag discharge door. Opening the slag discharge door allows the impurities to be directly discharged outside the device under the guidance of the arc-shaped plate, facilitating manual collection and treatment of welding slag inside the device. The injection pipe is inserted into the inner wall of the cold liquid chamber to inject coolant. Then, the connecting plate moves under the drive of the horizontal moving L-frame inside the device. The connecting plate moves the cold liquid chamber, and the coolant inside the cold liquid chamber coats the surface of the spiral rod, preventing the spiral rod from overheating and damaging its threads during long-term operation, thus preventing the device from malfunctioning.

[0015] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This laser cutting equipment for embroidery machines, with the cooperation of a three-jaw chuck, welding head, and grinding disc, rotates the three-jaw chuck to drive the pipe to be cut to rotate. During the rotation, the welding head starts to cut the tubular workpiece. During the cutting process, the three-jaw chuck rotates, which drives the pipe to rotate. During the rotational cutting process, the burrs generated on the edge of the pipe are ground off by the grinding disc, avoiding the need for manual trimming of the pipe after cutting, thereby increasing work efficiency.

[0016] 2. In this laser cutting equipment for embroidery machines, with the cooperation of the welding head, protective arc shell, and fixing plate, when the welding head contacts the surface of the workpiece, the protective arc shell also contacts the pipe to be cut below it. After contacting the workpiece, the protective arc shell prevents the laser beam and sparks generated during the cutting process from splashing everywhere, thus avoiding safety hazards in the workshop.

[0017] 3. In this laser cutting equipment for embroidery machines, the fixed plate moves the cold liquid chamber as the fixed plate moves, and the coolant inside the cold liquid chamber is then coated onto the surface of the spiral rod. This prevents the spiral rod from overheating during long-term operation, which could damage the threads on its surface and cause the device to malfunction. Attached Figure Description

[0025] The post-weld maintenance mechanism 8 includes a shallow limiting groove 801, a transmission gear 802, a telescopic vertical plate 803, and a reciprocating screw 804. The shallow limiting groove 801 is formed on the top outer wall of the welding chamber 1. The transmission gear 802 is fixedly connected to the top outer wall of the welding chamber 1. One end of the telescopic vertical plate 803 is fixedly connected to the bottom outer wall of the vertical moving plate 713, and the other end of the telescopic vertical plate 803 is slidably connected to the inner wall of the shallow limiting groove 801. The reciprocating screw 804 is rotatably connected to the inner wall of the telescopic vertical plate 803. The reciprocating screw 804 and the transmission gear 802 are driven by gears.

[0026] The post-weld maintenance mechanism 8 also includes a dust removal plate 805, a limiting ball block 806, and a vertical groove 807. The dust removal plate 805 is movably connected to the outer circumferential surface of the reciprocating screw 804, the limiting ball block 806 is fixedly connected to the left outer wall of the reciprocating screw 804, and the vertical groove 807 is opened on the inner wall of the welding head 6.

[0027] The post-weld maintenance mechanism 8 also includes a sliding crossbar 808, a protective arc shell 809, and a fixed spring plate 810. The sliding crossbar 808 is slidably connected to the inner wall of the welding head 6, the protective arc shell 809 is fixedly connected to the outer wall of the sliding crossbar 808, and the fixed spring plate 810 is fixedly connected to the outer wall of the welding head 6. The sliding crossbar 808 and the fixed spring plate 810 are connected by a spring. In this laser cutting equipment for embroidery machines, with the cooperation of the welding head 6, the protective arc shell 809, and the fixed plate 906, when the welding head 6 contacts the surface of the workpiece, the protective arc shell 809 also contacts the pipe to be cut below it. After contacting the workpiece, the protective arc shell 809, through its own shielding, prevents the laser beam and sparks generated during the cutting process from flying everywhere, thereby causing safety hazards in the workshop.

[0028] Working Principle: This device can cut tubular workpieces. Before operation, the bidirectional screw 716 is manually rotated. During rotation, the bidirectional spiral groove on the circumferential surface of the screw 716 drives the fixed bottom semicircles 717 at both ends to converge towards the center. As the fixed bottom semicircles 717 move towards the center, the top semicircle 718 and the connecting telescopic rod 719 also move towards the center, thus clamping one end of the tubular workpiece. Pulling the gripping rod 709 moves the device moving block 704 on the circumferential surface of the first screw 701, moving the grinding disc 706 to the bottom of the circumferential surface of the workpiece to be cut. Then, the other end is clamped on the inner wall of the three-grip chuck 703 to complete the preliminary work before cutting the workpiece. Subsequently, the second screw 711 is manually rotated, and the spiral groove on the circumferential surface of the second screw 711 drives the vertical moving plate 713 to move upward or downward at the limit of the limiting vertical rod 712. During the operation, the fixed unloading disc 714 moves, squeezing and limiting the pipe below, pressurizing it downwards to ensure close contact between the pipe and the grinding disc 706. Subsequently, the three-jaw chuck 703 rotates, causing the pipe to be cut to rotate as well. During this rotation, the welding head 6 starts cutting the tubular workpiece. The three-jaw chuck 703 rotates during the cutting process, causing the pipe to rotate as well. During the rotational cutting process, the burrs generated on the edges of the pipe are ground off by the grinding disc 706, avoiding the need for manual trimming after cutting, thus increasing work efficiency. At the same time, the motor starts, driving the screw rod 701 to rotate. During the rotation, the screw rod 701 drives the transmission block 715 to move under the limit of the welding chamber 1, thereby adjusting the distance between it and the power box 702 to accommodate pipes of different lengths.

[0029] After the device finishes its work, some debris and impurities will remain on its surface. Then, pulling the gripping rod 709 moves the vertical moving plate 713. During this movement, the vertical moving plate 713 moves the telescopic vertical plate 803 at the bottom. The telescopic vertical plate 803, in turn, moves the reciprocating screw 804. During this movement, the reciprocating screw 804 rotates through gear meshing with the transmission gear 802. As it rotates, the reciprocating screw 804, through the cross-shaped spiral grooves on its circumferential surface, drives the dust-sweeping plate 805 to clean the welding chamber 1. Under the limit, the device moves back and forth. During the movement, the slag removal plate 805 pushes the welding slag adhering to the surface of the device into the gap of the shallow limiting groove 801, so as to avoid excessive accumulation of welding slag on the device, which would affect the welding efficiency. When the device is welding, the welding head 6 moves downward. When the welding head 6 contacts the surface of the workpiece, the protective arc shell 809 also contacts the pipe to be cut below it. After contacting the workpiece, the protective arc shell 809 blocks the laser beam and sparks generated during the cutting process, thus preventing them from splashing everywhere and causing safety hazards in the workshop.

[0030] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the slag collecting rod 9 further includes a telescopic rod 901, a horizontal plate 902, and a dust sweeping brush 903. The telescopic rod 901 is fixedly connected to the bottom of the vertical moving plate 713, the horizontal plate 902 is fixedly connected to the bottom of the telescopic rod 901, and the dust sweeping brush 903 is fixedly connected to the bottom of the horizontal plate 902.

[0031] The slag collection rod 9 also includes an arc-shaped plate 904, a slag discharge door 905, and a connecting piece 906. The arc-shaped plate 904 is fixedly connected to the bottom inner wall of the welding chamber 1, the slag discharge door 905 is rotatably connected to the outer wall of the welding chamber 1, and the connecting piece 906 is fixedly connected to the outer wall of the transverse L-frame 708.

[0032] The slag collection rod 9 also includes a cold liquid chamber 907 and an injection pipe 908. The cold liquid chamber 907 is fixedly connected to the inner wall of the connecting plate 906, and the injection pipe 908 is slidably connected to the top inner wall of the cold liquid chamber 907. In this laser cutting device for embroidery machines, with the cooperation of the spiral rod 701, the cold liquid chamber 907, and the connecting plate 906, the connecting plate 906 moves the cold liquid chamber 907 during its movement. Subsequently, the coolant inside the cold liquid chamber 907 is coated onto the surface of the spiral rod 701 to prevent the spiral rod 701 from overheating during long-term operation, which could damage the threads on its surface and prevent the device from malfunctioning.

[0033] Working principle: Impurities on the device fall to the bottom of the device through the shallow limiting groove 801. Then, the movement of the vertical moving plate 713 drives the telescopic rod 901 to move. During the movement of the telescopic rod 901, the horizontal plate 902 at the bottom moves. During the movement of the horizontal plate 902, the dust sweeping brush 903 moves. During the movement of the dust sweeping brush 903, the impurities and dust on the top of the arc-shaped plate 904 are pushed to the vicinity of the slag discharge door 905. Then, opening the slag discharge door 905 allows the impurities to be guided by the arc-shaped plate 904. The slag is discharged directly to the outside of the device, facilitating manual collection and treatment of the welding slag inside the device. The injection pipe 908 is inserted into the inner wall of the cold liquid tank 907 to inject coolant. Then, the connecting plate 906 moves under the drive of the transverse L-frame 708 inside the device. During the movement of the connecting plate 906, the cold liquid tank 907 moves. Subsequently, the coolant inside the cold liquid tank 907 will coat the surface of the screw rod 701, preventing the screw rod 701 from overheating during long-term operation and causing damage to its surface threads, thus preventing the device from operating.
