Description

Technical Field

[0001] This utility model relates to the field of fabric cutting technology, and in particular to an automatic fabric cutting device with adjustable width. Background Technology

[0002] UD fabric, also known as unidirectional fabric, is a type of non-woven material / fabric. It is characterized by having a large amount of woven glass yarn or untwisted roving in one direction (usually the warp) and only a small amount of usually finer yarn in the other direction. This structure makes the full strength of UD fabric concentrated in the first direction, while the weft yarn mainly plays a reinforcing role. UD fabric has a wide range of applications in many fields.

[0003] Publication No. CN222251467U discloses an automatic UD fabric cutting device, including a worktable. A mounting frame is slidably mounted on the top of the worktable. Inside the mounting frame is a cutting mechanism for cutting the UD fabric. The cutting mechanism includes two sets of electric cylinders, symmetrically fixedly mounted on the inner top of the mounting frame. One end of the piston rod of each of the two sets of electric cylinders is fixedly connected to a mounting plate. A cutting blade is fixedly mounted at the center of the bottom of the mounting plate. Three sets of buffer components are mounted on both sides of the mounting plate on the cutting blade. A limiting plate for limiting the UD fabric is mounted at the bottom of the three sets of buffer components. Grooves are formed on both sides of the worktable. A drive mechanism for driving the mounting frame is installed inside each of the two grooves. A guiding mechanism for guiding the UD fabric is installed at one end of the worktable. This invention, through the design of the cutting mechanism and buffer components, uses the limiting plate to press and limit the UD fabric during cutting, thus improving the cutting accuracy of the UD fabric.

[0004] Existing cutting equipment requires long changeover and adjustment times and a lot of manual intervention, making it difficult to accurately locate fabric dimensions for cutting and reducing work efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an automatic fabric cutting device with adjustable width. The existing cutting equipment has the problems of long changeover and machine adjustment time, excessive manual intervention, inability to accurately locate the fabric size for cutting, and reduced work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An adjustable width automatic fabric cutting device includes a worktable. The top of the worktable is provided with two fabric guiding mechanisms and a fabric flattening mechanism. The fabric flattening mechanism is located between the two fabric guiding mechanisms. The top of the worktable is also provided with a fabric detection mechanism, a fabric cutting mechanism and a fabric pulling mechanism, which are arranged sequentially from left to right.

[0008] Preferably, the fabric guiding mechanism includes two first support plates, both of which are fixedly installed on the top of the workbench, and two guide rollers are rotatably installed between the two first support plates for guiding the fabric.

[0009] Preferably, the fabric flattening mechanism includes two linear motors, both of which are fixedly installed on the top of the worktable. The top of the two linear motors is equipped with the same U-shaped frame, and a flattening roller is rotatably installed inside the U-shaped frame. The two linear motors push the U-shaped frame to adjust its height, and the flattening roller supports the fabric, thus flattening the fabric.

[0010] Preferably, the fabric detection mechanism includes two second support plates, both of which are fixedly installed on the top of the workbench. A common top plate is fixedly installed on the top of both second support plates, and two laser sensors are mounted on the top of the top plate. Electric push rods are fixedly installed on the outer sides of both second support plates, and fabric guide rails are mounted on the output shafts of both electric push rods. Arc-shaped sliding surfaces are provided on the inner sides of both fabric guide rails. The two electric push rods push the two fabric guide rails to move, adjusting the distance between them to accommodate different fabric widths, limiting the fabric movement, and preventing the fabric from deviating during transport.

[0011] Preferably, the fabric cutting mechanism includes a cutting seat mounted on top of the workbench. The top of the cutting seat has a threaded rod with a cutting groove. Support rods are installed at the four corners of the top of the cutting seat. A horizontal plate is mounted on the top of the four support rods. Two cylinders are mounted on the top of the horizontal plate. A slide rail is mounted on the output shaft of the two cylinders. A slider is slidably mounted inside the slide rail. A mounting plate is fixedly mounted on the bottom of the slider. A cutting blade holder is mounted on the bottom of the mounting plate. A cutting motor is mounted on the cutting blade holder. A cutting blade is mounted on the output shaft of the cutting motor. The threaded rod with the cutting groove is rotatably mounted inside the slide rail via a bearing. A servo motor is mounted on the outside of the slide rail. The slider is threadedly connected to the outside of the threaded rod with the cutting groove. The servo motor drives the threaded rod with the cutting groove to rotate, which in turn drives the slider to move, thereby moving the cutting blade to the same size as the fabric, preventing the cutting blade from running idle and improving work efficiency.

[0012] Preferably, the material pulling mechanism includes two third support plates, both of which are fixedly installed on the top of the workbench. Two material pulling rollers are rotatably installed between the two third support plates. Two synchronous motors are installed on the outer side of one of the three third support plates. The output shafts of the two synchronous motors are fixedly installed with the two material pulling rollers. The two synchronous motors drive the two material pulling rollers to rotate, and the two material pulling rollers pull the fabric.

[0013] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0014] When the fabric enters the measurement module, the laser sensor scans the actual width of the fabric and uploads the data to the control terminal. The system compares the data with the preset cutting width and drives the servo motor to adjust the lateral position of the cutting mechanism. During the cutting process, the system continuously monitors the fabric width fluctuations and dynamically corrects the tool trajectory.

[0015] This device uses a sliding guide rail and laser sensor for coordinated adjustment: the cutting mechanism moves laterally along the guide rail, and the laser sensor detects the edge of the fabric in real time to achieve dynamic adjustment of the cutting width.

[0016] This device solves the problems of long changeover and machine adjustment time and excessive manual intervention in traditional cutting equipment by using sliding guide rail mechanical adjustment and laser sensing digital closed-loop control. It significantly improves the efficiency and accuracy of cutting multiple varieties and small batches of fabrics and is suitable for flexible manufacturing scenarios such as clothing and home textiles.

The fabric flattening mechanism 3 is located between the two fabric guiding mechanisms 2. The top of the worktable 1 is also provided with a fabric detection mechanism 4, a fabric cutting mechanism 5 and a material pulling mechanism 6, which are arranged from left to right.

[0026] like Figure 1 , Figure 2 As shown, in this embodiment, the fabric guiding mechanism 2 includes two first support plates 21, both of which are fixedly installed on the top of the workbench 1, and two guide rollers 22 are rotatably installed between the two first support plates 21 for guiding the fabric.

[0027] like Figure 1 , Figure 2 As shown, in this embodiment, the fabric flattening mechanism 3 includes two linear motors 31, both of which are fixedly installed on the top of the workbench 1. The top of the two linear motors 31 is equipped with the same U-shaped frame 32, and a flattening roller 33 is rotatably installed inside the U-shaped frame 32. The two linear motors 31 push the U-shaped frame 32 to adjust its height, and the flattening roller 33 supports the fabric, which can flatten the fabric.

[0028] like Figure 1 , Figure 2As shown, in this embodiment, the fabric detection mechanism 4 includes two second support plates 41, both of which are fixedly installed on the top of the workbench 1. The top of the two second support plates 41 is fixedly installed with the same top plate 42. Two laser sensors 43 are installed on the top of the top plate 42. Electric push rods 44 are fixedly installed on the outer sides of the two second support plates 41. Fabric guide rails 45 are installed on the output shafts of the two electric push rods 44. Arc-shaped sliding surfaces 46 are provided on the inner sides of the two fabric guide rails 45. The two electric push rods 44 push the two fabric guide rails 45 to move, adjust the distance between the two fabric guide rails 45 to adapt to different sizes of fabric width, limit the fabric, and prevent the fabric from deviating during transmission.

[0029] Specifically, the fabric feeding module pre-feeds 1m of material, and the laser sensor calibrates the reference width of the fabric width. The sensor model can be either Keyence IL-300 or equivalent (±0.05mm).

[0030] like Figure 4 , Figure 5 As shown, in this embodiment, the fabric cutting mechanism 5 includes a cutting seat 51, which is installed on the top of the workbench 1. A cutting groove threaded rod 511 is provided on the top of the cutting seat 51. Support rods 53 are installed at the four corners of the top of the cutting seat 51. A common horizontal plate 52 is installed on the top of the four support rods 53. Two cylinders 55 are installed on the top of the horizontal plate 52. A common slide rail 54 is installed on the output shaft of the two cylinders 55. A slider 57 is slidably installed inside the slide rail 54. A mounting plate 58 is fixedly installed at the bottom of the slider 57, and a cutting blade is installed at the bottom of the mounting plate 58. A cutting motor 512 is mounted on the cutter holder 59, and a cutting blade 510 is mounted on the output shaft of the cutting motor 512. A cutting groove threaded rod 511 is rotatably mounted in the slide rail 54 via a bearing. A servo motor 56 is mounted on the outside of the slide rail 54, and a slider 57 is threadedly connected to the outside of the cutting groove threaded rod 511. The servo motor 56 drives the cutting groove threaded rod 511 to rotate, and the cutting groove threaded rod 511 drives the slider 57 to move, which in turn drives the cutting blade 510 to move to the same size as the fabric, thus avoiding the cutting blade 510 running idle and improving work efficiency.

[0031] Specifically, it uses a servo motor (Panasonic MINAS A6 series, 750W) and a ball screw (32mm diameter, 10mm lead).

[0032] like Figure 1 , Figure 2As shown, in this embodiment, the material pulling mechanism 6 includes two third support plates 62, both of which are fixedly installed on the top of the workbench 1. Two material pulling rollers 61 are rotatably installed between the two third support plates 62. Two synchronous motors 63 are installed on the outer side of one of the three third support plates 62. The output shafts of the two synchronous motors 63 are fixedly installed with the two material pulling rollers 61. The two synchronous motors 63 drive the two material pulling rollers 61 to rotate, and the two material pulling rollers 61 pull the fabric.

[0033] Specifically, it features an upper and lower roller design, with the surface coated with high-friction coefficient silicone (Shore hardness 70-80HA) and a diameter of Φ100mm.

[0034] In this embodiment, the operation is as follows: When in use, the power supply and control terminal (embedded controller, such as the STM32F4 series, which calculates the average fabric width in real time and eliminates abnormal fluctuations) are connected. The fabric is passed through the two guide mechanisms 2, specifically between the two guide rollers 22, and wrapped around the top side of the flattening roller 33. It then passes through the other two guide rollers 22, extending between the two fabric guide rails 45, and through the two pulling rollers 61. Two synchronous motors 63 drive the two pulling rollers 61 to rotate, pulling the fabric. Two infrared monitors 43 monitor the fabric, scanning the actual fabric width and uploading the data to the control terminal. Electric push rod 44 moves two fabric guide rails 45, adjusting the distance between them to accommodate different fabric widths and limiting the fabric to prevent it from deviating during transport. After obtaining the fabric dimensions, two cylinders 55 push slide rail 54 downward. Slide rail 54 drives cutter 510 downward through slider 57, mounting plate 58, and cutter holder 59. Cutting motor 512 drives cutter 510 to rotate and cut the fabric. Servo motor 56 drives cutting groove threaded rod 511 to rotate. Cutting groove threaded rod 511 drives slider 57 to move, which in turn drives cutter 510 to move to the same size as the fabric, preventing cutter 510 from running idle and improving work efficiency.
