Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and in particular to a material unloading device for a laser tube cutting machine. Background Technology

[0002] Laser cutting technology, with its advantages of high precision and high efficiency, has been widely used in the field of metal pipe processing. After the laser pipe cutting machine completes the pipe cutting, the cut pipe needs to be stably received and transferred to the collection area by a material unloading device to avoid disorderly accumulation or damage from impact.

[0003] However, traditional unloading devices often use fixed receiving platforms or simple slide structures, which are difficult to adapt to changes in pipe diameter, cutting position, and equipment model. When the length and weight of the cut pipes vary significantly, the fixed-height receiving mechanism can easily cause the pipes to slip and deviate, or even become stuck, requiring frequent manual adjustments and severely impacting continuous processing efficiency. Some unloading devices rely on manual operation to flip or move the pipes, which not only increases labor intensity but also poses safety hazards; while flipping mechanisms driven by a single motor lack synchronous control, making it easy for the two sides to move asynchronously, causing the pipes to tilt or fall during the tilting process. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a blanking device for a laser tube cutting machine, which effectively solves the problems of existing blanking devices having no height adjustment capability, reliance on manual operation for flipping or handling tubes, low automation level, and low efficiency.

[0005] This utility model adopts the following technical solution: a laser tube cutting machine unloading device, including a laser tube cutting machine frame, a fixed chuck frame, and a unloading slide rail. At least one pair of scissor-type lifting frames are provided on the unloading slide rail. A flipping support frame mechanism is provided on the top of the scissor-type lifting frame. The flipping support frame mechanism includes two sets of bearing seats, with a lead screw rotatably connected between each set of bearing seats. A sliding block is threaded onto the surface of the lead screw. A lifting frame is provided above the sliding block, and several lifting rollers are rotatably connected to the lifting frame. One end of the lifting frame is hinged to the top of two sliding blocks. L-shaped connecting rods are rotatably connected to both sides of the lifting frame. A fixed seat and a reduction motor are installed on the top of the scissor-type lifting frame. Both ends of the fixed seat are rotatably connected to one end of the L-shaped connecting rod. Two driving sprockets are connected to the output end of the reduction motor. A driven sprocket is connected to one end of each of the two lead screws. The driven sprockets are connected to the corresponding driving sprockets via chain drive.

[0006] Furthermore, a material discharge chute is provided on one side of the material discharge slide rail.

[0007] Furthermore, the scissor lift includes four steel connecting rods, which intersect in pairs to form two X-shaped hinge points. The top and bottom of the four steel connecting rods are respectively connected to the platform and the base. The base is equipped with four guide wheels, which roll in cooperation with the unloading slide rail. A connecting plate is provided between the lower ends of each pair of steel connecting rods. A threaded rod is provided between the two connecting plates. The threaded rod is rotatably connected to one of the connecting plates and threadedly connected to the other connecting plate. A hand crank is connected to one end of the threaded rod. The bearing seat and the reduction motor are both installed on the top of the platform.

[0008] Furthermore, guide blocks are arranged parallel to each other on both sides of the lead screw at the top of the platform, and the guide blocks are slidably connected to the sliding block.

[0009] Furthermore, the surface of the lifting roller is covered with a polyurethane anti-slip layer.

[0010] The advantages of this invention are as follows: The scissor lift frame adjusts its height by hand-cranking a threaded rod, and moves along the slide rail with guide wheels, precisely matching the cutting position of the fixed chuck to adapt to different pipe diameters or cutting heights, ensuring the lifting roller stably receives the cut pipe. A geared motor drives the synchronous rotation of two lead screws, and symmetrical movement of the sliding block is achieved through sprocket transmission. Combined with the lever effect of the L-shaped connecting rod, linear motion is converted into the flipping action of the lifting frame, enabling automatic tilting of the pipe into the slip hopper, reducing manual intervention and improving material discharge efficiency.

[0018] See Figure 1-4 As shown, a laser tube cutting machine unloading device includes a laser tube cutting machine frame 1, a fixed chuck frame 2, and an unloading slide rail 3. At least one pair of scissor-type lifting frames 4 are mounted on the unloading slide rail 3. A tilting support mechanism 5 is mounted on the top of the scissor-type lifting frames 4. The tilting support mechanism 5 includes two sets of bearing seats 501, with a lead screw 502 rotatably connected between each set of bearing seats 501. A sliding block 503 is threaded onto the surface of the lead screw 502. A lifting frame 504 is mounted above the sliding block 503, and several [unclear - possibly referring to components or components] are rotatably connected to the lifting frame 504. The lifting roller 505 and the lifting frame 504 are hinged at one end to the top of the two sliding blocks 503. Both sides of the lifting frame 504 are rotatably connected to L-shaped connecting rods 506. The top of the scissor lift frame 4 is equipped with a fixed seat 507 and a reduction motor 508. Both ends of the fixed seat 507 are rotatably connected to one end of the L-shaped connecting rod 506. The output end of the reduction motor 508 is connected to two drive sprockets 509. One end of each of the two lead screws 502 is connected to a driven sprocket 510. The driven sprockets 510 and the corresponding drive sprockets 509 are connected by chain drive.

[0019] A material discharge chute 6 is provided on one side of the material discharge slide rail 3, which uses the tilt angle to guide the pipe to slide down to the designated area by gravity.

[0020] The scissor lift frame 4 includes four steel connecting rods 41, which intersect in pairs to form two X-shaped hinge points. The top and bottom of the four steel connecting rods 41 are connected to the platform 42 and the base 43, respectively. The base 43 is equipped with four guide wheels 44, which roll in cooperation with the unloading slide rail 3. A connecting plate 45 is provided between the lower ends of each pair of steel connecting rods 41. A threaded rod 46 is provided between the two connecting plates 45. The threaded rod 46 is rotatably connected to one of the connecting plates 45 and threadedly connected to the other connecting plate 45. One end of the threaded rod 46 is connected to a hand crank 47. The bearing seat 501, the fixed seat 507, and the geared motor 508 are all installed on the top of the platform 42. The distance between the connecting plates 45 is adjusted by driving the threaded rod 46 through the hand crank 47, thereby changing the cross angle of the four steel connecting rods 41 and realizing the vertical lifting of the platform 42. The guide wheel 44 cooperates with the slide rail 3 to ensure the stability of movement. The manual adjustment structure is simple and reliable, with low maintenance costs. In addition, the guide wheel 44 is designed to avoid deviation during lifting and improving the height positioning accuracy.

[0021] The top of the platform 42 is provided with parallel guide blocks 511 on both sides of the lead screw 502. The guide blocks 511 are slidably connected to the sliding block 503, which restricts the sliding block 503 to move only along the axial direction of the lead screw 502, so as to avoid deflection or jamming caused by uneven force.

[0022] The surface of the lifting roller 505 is covered with a polyurethane anti-slip layer. The polyurethane material has both a high coefficient of friction and elasticity, which increases the friction between the lifting roller and the tube to prevent slippage.

[0023] Working principle: When the laser tube cutting machine starts working, the tube is clamped by the fixed chuck frame 2 and after being cut, the scissor lift frame 4 is pushed close to the tube drop position. Since the position of the fixed chuck frame 2 is fixed, the height of the lifting roller 505 needs to be adjusted so that the tube can be stably placed on the lifting roller 505 after cutting. The threaded rod 46 is driven to rotate by the hand crank 47, changing the spacing of the connecting plate 45, so that the X-shaped hinge structure of the scissor lift frame 4 deforms. The changing angle of the four steel connecting rods 41 causes the platform 42 to rise and fall vertically. The cut pipe is supported by the lifting roller 505. The reduction motor 508 drives the driven sprocket 510 on the lead screw 502 to rotate through the drive sprocket 509, which in turn drives the lead screw 502 to rotate. This causes the sliding block 503 to move along the surface of the lead screw. The sliding block 503 pushes the lifting frame 504 through the hinge point. The L-shaped connecting rod 506 converts the linear displacement into angular displacement, causing the lifting frame 504 to flip along the rotational connection between the L-shaped connecting rod 506 and the lifting frame 504. The pipe supported by the lifting roller 505 falls into the material dumping hopper 6 due to gravity and is collected.
