Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a laser fabric cutting machine for processing container bags. Background Technology

[0002] The FIBC laser cutting equipment is an automated processing equipment specifically designed for cutting FIBC materials. It consists of a laser generator, CNC system, automatic feeding mechanism, cutting worktable and cooling system. It can automatically complete the cutting of FIBC body, straps, bottom and other parts according to preset drawings.

[0003] Because FIBCs are mostly made of thick woven fabric with low elasticity, they are generally pulled manually to cut the fabric and pull the uncut fabric to a suitable length before being cut by a laser cutting machine. This limits the overall cutting efficiency. Therefore, the existing Chinese utility model patent (CN213925608U) discloses a laser fabric cutting machine. This application uses an adsorption mechanism to hold the fabric, and a drive mechanism to move the fabric for feeding. After feeding, the adsorption mechanism releases the fabric, and the drive mechanism returns the adsorption mechanism to its original position, thus achieving fabric feeding. However, this traction method can only pull one end of the uncut fabric, and cannot unload the cut fabric. Furthermore, the woven fabric used in FIBCs is mostly polypropylene, with a smooth surface and large fiber gaps, resulting in poor sealing during adsorption and easy loss of vacuum, which damages the seal of the adsorption surface, leading to localized air leakage and ultimately causing the fabric to fall off.

[0008] As a further preferred embodiment of this utility model, the workbench has two lower insertion ports, and the two lower insertion ports are respectively located on the same extension line as the corresponding suspension plate, which enables the extended cantilever to drive the lower clamping blocks on both sides to be inserted into the lower insertion ports and located below the fabric cut.

[0009] As a further preferred embodiment of this utility model, two sliding grooves are provided on one side of the mounting groove to provide guiding conditions for the radial movement of the connecting block. A connecting through groove is also provided on the inner side of the mounting groove between the two sliding grooves, and the two mounting grooves are connected through the connecting through groove cavity. A pin is inserted and connected at the lower position of the mounting groove to provide conditions for the rotational connection of the lower clamping block in the mounting groove.

[0010] As a further preferred embodiment of this utility model, a fixing block is fixedly connected to one side of the lower clamping block, and the fixing block is rotatably connected to the pin shaft. The bottom of the lower clamping block is provided with a slope and is at the same angle as the bottom slope of the suspension plate, so that when the suspension plate moves down through the platform, it can pass through the connection between the cut and uncut pieces of fabric by utilizing the slope of the suspension plate and the bottom of the lower clamping block.

[0011] As a further preferred embodiment of this utility model, a connecting rod is inserted and connected at the center of the suspension plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the clamping structure of the upper clamping block and the lower clamping block that can be rotated under force allows the lower clamping block to be inserted under the cut and uncut fabrics, adapting to the characteristics of thick woven materials in container bags. With the help of a cylinder, connecting rod, limiting block, and connecting block, the upper clamping block is moved down, thereby causing the two sets of lower clamping blocks and upper clamping blocks on both sides of the suspension plate to clamp one end of the two pieces of fabric and move to one side, realizing the unloading of the cut fabric and the traction loading of the uncut fabric, preventing the fabric from slipping, requiring no manual intervention, and improving traction stability.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-7As shown, the present invention provides a laser fabric cutting machine for processing container bags, comprising a first frame 1, a worktable 2 fixedly connected inside the first frame 1, a first X-axis moving platform 3 movably connected to the first frame 1, a Y-axis moving platform 4 movably connected to the first X-axis moving platform 3, a Z-axis moving platform 5 movably connected to one side of the Y-axis moving platform 4, an extended cantilever 6 fixedly connected to one side of the Z-axis moving platform 5, a laser cutting head 7 fixedly connected to one side of the extended cantilever 6, a second frame 8 fixedly connected to the first frame 1 near the first X-axis moving platform 3, a second X-axis moving platform 9 movably connected to the second frame 8, and multiple mounting brackets fixedly connected to one side of the second X-axis moving platform 9. Mounting frame 10, with motor 11 fixedly connected to the top of mounting frame 10, and lead screw 12 rotatably connected inside mounting frame 10. The top of lead screw 12 is fixedly connected to the output end of motor 11. Platform 13 is slidably connected to one side of mounting frame 10, and internal threaded hole block is fixedly connected to the side of platform 13 relative to lead screw 12 and threadedly connected to lead screw 12. Bracket 14 is fixedly connected to platform 13, and cylinder 15 is fixedly connected to bracket 14. Suspension plate 16 is fixedly connected to the bottom of platform 13. Mounting grooves 17 are opened on both sides of suspension plate 16. Lower clamping block 18 is movably connected inside laser cutting head 7. Upper clamping block 20 is movably connected to mounting groove 17 above lower clamping block 18 through connecting block 19.

[0025] like Figure 1 As shown, the first X-axis moving platform 3, the Y-axis moving platform 4, the Z-axis moving platform 5, the laser cutting head 7, the second X-axis moving platform 9, and the motor 11 are electrically connected to an external main controller via cables. The cylinder 15 is connected to an external air pump via an air pipe, thereby cooperating with the external main controller to set parameters to realize the start and stop actions of the first X-axis moving platform 3, the Y-axis moving platform 4, the Z-axis moving platform 5, the laser cutting head 7, the second X-axis moving platform 9, and the motor 11.

[0026] like Figures 1-2 As shown, the workbench 2 has two lower insertion ports 21, and the two lower insertion ports 21 are respectively located on the same extension line as the corresponding suspension plate 16, which allows the extended cantilever 6 to drive the lower clamping blocks 18 on both sides to be inserted into the lower insertion ports 21 and located below the fabric cut.

[0027] like Figures 1-7As shown, two sliding grooves 22 are provided on one side of the mounting groove 17 to provide guidance for the radial movement of the connecting block 19. A connecting through groove 24 is also provided on the inner side of the mounting groove 17 between the two sliding grooves 22, and the two mounting grooves 17 are connected through the cavity of the connecting through groove 24. A pin 23 is inserted and connected at the lower position of the mounting groove 17 to provide conditions for the rotational connection of the lower clamping block 18 in the mounting groove 17. A fixing block 27 is fixedly connected to one side of the lower clamping block 18, and the fixing block 27 is rotatably connected to the pin 23. The bottom of the lower clamping block 18 is provided with a slope and is at the same angle as the bottom slope of the suspension plate 16, so that when the suspension plate 16 moves down through the platform 13, the slope of the bottom of the suspension plate 16 and the lower clamping block 18 can pass through the connection point of the cut and uncut pieces of fabric. A connecting rod 28 is inserted and connected at the center of the suspension plate 16. The bottom of the connecting rod 28 extends into the connecting through groove 24 and is fixedly connected to a limit block 29. The top of the connecting rod 28 is connected to the cylinder through a coupling. One end of the piston rod of cylinder 15 is fixedly connected. The cooperation between cylinder 15, connecting rod 28, limiting block 29, and connecting block 19 enables the two upper clamping blocks 20 to move radially synchronously on one side of suspension plate 16. A groove 25 is provided at the center of one side of connecting block 19. Multiple balls 26 are rotatably connected to the connecting blocks 19 located on both sides of the groove 25. The two connecting blocks 19 are slidably connected to one side of the corresponding mounting groove 17. The balls 26 are slidably connected in the corresponding sliding groove 22. The groove 25 is inserted and connected to the connecting rod 28 and limiting block 29 on one side. The two connecting blocks 19 and the two upper clamping blocks 20 are fixed by bolts. The two upper clamping blocks 20 are placed on one side of the connecting blocks 19 and the two connecting blocks 19 are slidably connected in the corresponding mounting groove 17 by bolts. The upper clamping blocks 20 can be driven to move radially by the cooperation of connecting rod 28, limiting block 29, and connecting block 19, so that the upper clamping blocks 20 and lower clamping blocks 18 can clamp one end of the fabric.

[0028] It should be noted that this utility model is a laser fabric cutting machine for processing FIBCs (Flexible Intermediate Bulk Containers). In use, the cutting parameters are first set via an external controller. Then, the FIBC fabric to be processed is laid flat on the worktable 2, ensuring that the area to be cut is aligned with the working position below the laser cutting head 7. After the parameters are set, the external controller sends a start signal via cable to the first X-axis moving platform 3, the Y-axis moving platform 4, and the Z-axis moving platform 5. The first X-axis moving platform 3 moves along the X-axis on the first frame 1, the Y-axis moving platform 4 adjusts its position along the Y-axis on the first X-axis moving platform 3, and the Z-axis moving platform 5 adjusts its height along the Z-axis on the Y-axis moving platform 4. These three components work together to move the extended cantilever 6 and the laser cutting head 7, ensuring that the laser cutting head 7 is precisely aligned with the area to be cut on the fabric. Then, the external controller controls the laser cutting head 7 to start, and the laser cutting head 7 emits a laser beam to cut the fabric. During the cutting process, the Z-axis moving platform 5 moves horizontally on the Y-axis moving platform 4, thus performing a transverse cut on the fabric.

[0029] After a section of fabric is cut, the cut fabric needs to be unloaded and the uncut fabric needs to be loaded. At this time, the external controller sends a signal to the second X-axis moving platform 9. The second X-axis moving platform 9 moves along the X-axis on the second frame 8, driving the mounting frame 10 to the fabric cut position. Then, the external controller controls the motor 11 to start. The output of the motor 11 drives the lead screw 12 to rotate inside the mounting frame 10. When the lead screw 12 rotates, it drives the platform 13 to slide downward along one side of the mounting frame 10. The platform 13 drives the suspension plate 16 to move downward synchronously until the bottom of the suspension plate 16 and the bottom of the lower clamping block 18 pass through the connection between the cut and uncut fabric. Since the cut points of the two sections of fabric are in contact with each other, the bottom of the lower clamping block 18 is limited by the fabric and rotates a certain angle on the pin 23 with the fixed block 27 as the axis. This ensures that the lower clamping block 18 and the lower end of the suspension plate 16 move smoothly to the position below the fabric and are inserted into the lower insertion port. Inside 21, the lower clamping block 18 resets itself due to gravity and remains perpendicular to the suspension plate 16. Then, the external air pump supplies air to the cylinder 15 through the air pipe. The piston rod of the cylinder 15 extends downward, driving the connecting rod 28 to move downward within the suspension plate 16. The limiting block 29 at the bottom of the connecting rod 28 moves downward synchronously and pushes the connecting block 19 to slide downward along the slide groove 22 within the mounting groove 17. The connecting block 19 drives the upper clamping block 20 to move downward synchronously, so that the upper clamping block 20 cooperates with the lower clamping block 18 to clamp the ends of the cut and uncut fabrics respectively. After clamping, the external main controller controls the second X-axis moving platform 9 to move in the opposite direction. The second X-axis moving platform 9 drives the mounting frame 10, the platform 13, the suspension plate 16, and the two clamped fabrics to move. The cut fabric moves with the clamping structure to the outside of the worktable 2 to complete the unloading. The uncut fabric is pulled a certain length so that the cutting position is at the processing position below the laser cutting head 7.

[0030] Then, the piston rod of cylinder 15 retracts upward, driving the connecting rod 28, limit block 29, connecting block 19 and upper clamping block 20 to move upward, releasing the clamping of the fabric. At the same time, motor 11 rotates in the opposite direction, driving the platform 13 and suspension plate 16 to move upward and reset through lead screw 12. The second X-axis moving platform 9 also moves and resets, preparing for the next cutting, unloading and loading cycle.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
