Technical Field

[0001] This application relates to the field of fabric cutting machines, and more particularly to a fabric cutting machine with a positioning device. Background Technology

[0002] Polyester composite yarn imitation wool 3D blankets are widely used due to their excellent performance. They offer advantages such as a soft, fluffy feel and good warmth retention. In the production process of polyester composite yarn imitation wool 3D blankets, fabric cutting machines are typically used to cut the fabric.

[0003] Chinese Patent CN219326951U discloses a fabric cutting machine, including a worktable. The worktable has two parallel sliding grooves on its two sides along its length. The worktable has two drive components corresponding to the two sliding grooves. Two first mounting blocks are slidably mounted on the worktable, with their bottoms corresponding to the two drive components. A cutting wheel with a sliding direction perpendicular to the length of the worktable is slidably mounted between the two first mounting blocks. Two lower clamping rollers for clamping fabric passing through the worktable are rotatably mounted on the worktable. Two sets of fabric pulling components for pulling the fabric are slidably mounted on the worktable.

[0004] Regarding the aforementioned technologies, when the cutter moves and cuts various fabrics, the force applied by the cutter to the fabric can easily cause irregular wrinkles. These wrinkles can hinder the cutter from moving smoothly along the predetermined path, resulting in skewed or offset cutting lines and affecting the cutting effect. Utility Model Content

[0005] In order to reduce fabric wrinkles and improve cutting results, this application provides a fabric cutting machine with a positioning device.

[0006] The fabric cutting machine with a positioning device provided in this application adopts the following technical solution:

[0007] A fabric cutting machine with a positioning device includes a frame, a cutter, and a moving assembly. The moving assembly is used to drive the cutter to move. The cutter has pressure plates on both sides along the fabric transport direction. The pressure plates are used to contact the fabric. The pressure plates are connected to a lifting component, which is connected to the frame. The lifting component is used to drive the pressure plates to move and move the pressure plates closer to or away from the fabric.

[0008] By adopting the above technical solution, when the cutter cuts the fabric, the lifting component drives the pressure plate to press the fabric, so that the fabric on both sides of the cutter is pressed by the pressure plate, thereby reducing the fabric wrinkles caused when the cutter moves to cut the fabric and improving the cutting effect.

[0009] Optionally, the lifting component is connected to a drive assembly and a fabric pulling roller. There are two fabric pulling rollers, which are respectively located on both sides of the fabric width direction. The fabric pulling rollers are used to contact the fabric. The drive assembly is used to drive the fabric pulling rollers to move and flatten the fabric. The lifting component is used to drive the fabric pulling rollers to contact the fabric with the pressure plate in sequence.

[0010] By adopting the above technical solution, during use, the lifting component drives the fabric pulling roller to move and make the fabric pulling roller contact with the fabric. After the fabric pulling roller contacts the fabric, the drive component drives the two fabric pulling rollers to move and make the fabric pulling rollers flatten the fabric. After the fabric is flattened, the lifting component drives the pressure plate to move and make the pressure plate contact with the fabric, thereby reducing the wrinkles of the fabric and improving the cutting effect.

[0011] Optionally, the lifting component is connected to a mounting plate, the mounting plate having a moving groove, the driving assembly including a threaded rod, a first motor, and a slider, the length direction of the threaded rod being consistent with the length direction of the moving groove, the threaded rod being rotatably connected to the inner wall of the moving groove, the threaded rod including a positive thread section and a negative thread section, two sliders being provided, one slider being threaded onto the positive thread section, and the other slider being threaded onto the negative thread section, each of the fabric pulling rollers being connected to each slider, the first motor being connected to the mounting plate, and the output shaft of the first motor being connected to one end of the threaded rod.

[0012] By adopting the above technical solution, the first motor drives the threaded rod to rotate, thereby driving the two sliders to slide and connect in the moving groove along the length direction of the moving groove. The sliders drive the fabric pulling roller to move, thereby driving the two fabric pulling rollers to move closer or further apart, which facilitates the movement of the fabric pulling rollers.

[0013] Optionally, the cutter is provided with adjusting rollers on both sides along the fabric transport direction. The adjusting rollers are connected to adjusting components, which are used to drive the adjusting rollers to move and cause the adjusting rollers to tension the fabric.

[0014] By adopting the above technical solution, the adjusting roller tensions the fabric during use, thereby further reducing fabric wrinkles and improving the cutting effect.

[0015] Optionally, the adjusting component includes a spring and a movable block. The adjusting roller is rotatably connected to the movable block. The frame has a connecting hole. The movable block is slidably fitted into the connecting hole. One end of the spring is connected to the connecting hole, and the other end of the spring is connected to the movable block. The spring drives the movable block to move and causes the adjusting roller to tension the fabric.

[0016] By adopting the above technical solution, during use, the spring drives the moving block to move according to the fabric tension, and the adjusting roller follows the moving block to make the adjusting roller tighten the fabric and reduce fabric wrinkles.

[0017] Optionally, the fabric roller has several protrusions connected to its periphery for contacting the fabric.

[0018] By adopting the above technical solution, protrusions are added to increase the friction between the fabric roller and the fabric, making it easier for the fabric roller to flatten the fabric.

[0019] Optionally, a dust suction hood is provided below the fabric pulling roller. The dust suction hood is located on one side of the frame along the width of the fabric. The dust suction hood is connected to an air pump, and the opening of the dust suction hood faces upward.

[0020] By adopting the above technical solution, after the fabric is cut, the drive component drives the fabric pulling roller to approach the dust collection hood, and the air pump draws air into the dust collection hood, so that negative pressure is formed inside the dust collection hood, thereby sucking impurities on the surface of the fabric pulling roller into the dust collection hood, thereby reducing impurities on the surface of the fabric pulling roller and reducing secondary pollution to the fabric caused by impurities on the surface of the fabric pulling roller.

[0021] Optionally, a brush roller is rotatably connected to the inner wall of the dust hood, the brush roller being used to contact the fabric roller, and a rotating component is connected to the dust hood, the rotating component being used to drive the brush roller to rotate.

[0022] By adopting the above technical solution, when the dust hood cleans the fabric roller, the brush roller contacts the fabric roller, and the rotating part drives the brush roller to rotate. While the brush roller cleans the fabric roller, it also drives the fabric roller to rotate, which makes it easier for the dust hood to clean the periphery of the fabric roller and further reduce impurities on the surface of the fabric roller.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the cutter cuts the fabric, the lifting device drives the pressure plate to press the fabric, so that the fabric on both sides of the cutter is pressed by the pressure plate, thereby reducing the wrinkles in the fabric caused by the movement of the cutter and improving the cutting effect.

[0025] 2. During use, the lifting component drives the fabric pulling roller to move and make the fabric pulling roller contact with the fabric. After the fabric pulling roller contacts the fabric, the drive component drives the two fabric pulling rollers to move and make the fabric pulling rollers flatten the fabric. After the fabric is flattened, the lifting component drives the pressure plate to move and make the pressure plate contact with the fabric, thereby reducing the wrinkles of the fabric and improving the cutting effect.

[0026] 3. When using, adjust the roller to tension the fabric, thereby further reducing fabric wrinkles and improving the cutting effect. Attached Figure Description

The length direction of the pressure plates 300 is consistent with the width direction of the fabric, and the two pressure plates 300 are located on both sides of the cutter along the fabric transport direction. The cutter 200 is used to cut the fabric. The pressure plates 300 are used to press down on the fabric when the cutter 200 cuts the fabric. When the cutter 200 cuts the fabric, the pressure plates press down on the fabric, thereby reducing the wrinkles in the fabric when the cutter 200 moves and improving the cutting effect.

[0035] Reference Figure 1 and Figure 3The cutter 200 has adjusting rollers 400 on both sides along the fabric transport direction. The length direction of the adjusting rollers 400 is consistent with the width direction of the fabric, and the adjusting rollers 400 are connected to the frame 100 through adjusting members 500. The adjusting members 500 are used to drive the adjusting rollers 400 to move and drive the adjusting rollers 400 to tension the fabric. The frame 100 has a connecting hole 110 at the beginning. The length direction of the connecting hole 110 is consistent with the vertical direction. The adjusting member 500 is connected in the connecting hole 110. The adjusting member 500 includes a spring 510 and a moving block 520.

[0036] Reference Figure 1 and Figure 3 The adjusting roller 400 is rotatably connected to the movable block 520, which slides vertically against the inner wall of the connecting hole 110. The spring 510 is aligned with the vertical direction in length. The bottom end of the spring 510 is connected to the bottom inner wall of the connecting hole 110, and the top end of the spring 510 is connected to the movable block 520. The spring 510 drives the movable block 520 to move and causes the adjusting roller 400 to tension the fabric.

[0037] Reference Figure 3 The pressure plate 300 includes a first plate 330 and a second plate 340. The length direction of the first plate 330 is consistent with the width direction of the fabric, and the length direction of the second plate 340 is consistent with the fabric transport direction. The second plate 340 is connected to the middle of the first plate 330. The second plate 340 is provided with a lifting component, which is a first cylinder 120. The first cylinder 120 is connected to the frame 100, and the length direction of the first cylinder 120 is consistent with the vertical direction. The first cylinder 120 is provided with a mounting plate 600.

[0038] Reference Figure 3 The length of the mounting plate 600 is aligned with the width of the fabric. The second plate 340 is connected to the mounting plate 600 via a movable rod 310. The bottom end of the movable rod 310 is connected to the top of the second plate 340. The length of the movable rod 310 is aligned with the vertical direction. The movable rod 310 passes through and slides along its length onto the mounting plate 600. A support plate 320 is connected to the top of the movable rod 310, and the piston rod of the first cylinder 120 is connected to the support plate 320. A limiting plate 311 is connected to the end of the movable rod 310 near the second plate 340. The limiting plate 311 is located below the mounting plate 600 and is designed to contact the bottom of the mounting plate 600.

[0039] Reference Figure 3 and Figure 4The mounting plate 600 is equipped with fabric pulling rollers 610. Two fabric pulling rollers 610 are provided, positioned on either side of the second plate 340 along the width direction of the fabric. The length of the fabric pulling rollers 610 is aligned with the fabric transport direction. The fabric pulling rollers 610 are connected to the mounting plate 600 via a drive assembly 700. Several protrusions 611, made of rubber, are connected to the periphery of the fabric pulling rollers 610. These protrusions 611 are for contacting the fabric.

[0040] Reference Figure 3 and Figure 4 The mounting plate 600 has a moving groove 620, the length of which is aligned with the width of the fabric. The drive assembly 700 includes a threaded rod 710, a first motor 720, and sliders 730. The threaded rod 710 is rotatably connected to the inner wall of the moving groove 620, and includes a positive thread section 711 and a negative thread section 712. Two sliders 730 are provided, sliding along the width of the fabric and engaging with the inner wall of the moving groove 620. One slider 730 is threaded onto the positive thread section 711, and the other slider 730 is threaded onto the negative thread section 712. Each fabric pulling roller 610 is connected to its respective slider 730. The first motor 720 is connected to one end of the mounting plate 600 along its length, and the output shaft of the first motor 720 is connected to one end of the threaded rod 710. When in use, after the fabric roller 610 comes into contact with the fabric, the first motor 720 drives the threaded rod 710 to rotate, thereby driving the two fabric rollers 610 to move and flatten the fabric, thereby reducing the wrinkles of the fabric. After flattening, the two fabric rollers 610 press the two ends of the fabric respectively, thereby improving the cutting effect.

[0041] Reference Figure 3 and Figure 5The frame 100 is connected to a second cylinder 130, the length of which is aligned with the vertical direction. The piston rod of the second cylinder 130 is connected to a moving plate 140, the length of which is aligned with the width of the fabric. The moving plate 140 is connected to a moving assembly 800. The moving plate 140 has a sliding groove 141, the length of which is aligned with the length of the moving plate 140. The moving assembly 800 includes a lead screw 810, a second motor 820, and a connecting block 830. The lead screw 810 is rotatably connected to the inner wall of the sliding groove 141, the second motor 820 is connected to the moving plate 140, and the output shaft of the second motor 820 is connected to the lead screw 810. The connecting block 830 is threaded onto the lead screw 810 and slides along the length of the moving plate 140 within the sliding groove 141. The cutter 200 is rotatably connected to the bottom of the connecting block 830. The connecting block 830 is connected to the third motor 831. The third motor 831 is connected to the connecting block 830. The output shaft of the third motor 831 is connected to the cutter 200. The central axis of the output shaft of the third motor 831 is collinear with the central axis of the cutter 200.

[0042] Reference Figure 1 and Figure 4 Dust hoods 900 are installed at both ends of the mounting plate 600 along its length. The dust hoods 900 are connected to the frame 100, and their length is aligned with that of the fabric roller 610. The openings of the dust hoods 900 face upwards. An air extraction pipe 910 is connected to the dust hood 900, and the other end of the air extraction pipe 910 is connected to an air pump 920. A collection box 930 is connected to the middle of the air extraction pipe 910, and the collection box 930 is located between the dust hood 900 and the air pump 920. A filter plate 931 is connected inside the collection box 930, and the filter plate 931 is located at the end of the collection box 930 closest to the air pump 920.

[0043] Reference Figure 1 and Figure 4 A brush roller 940 is rotatably connected to the inner wall of the dust collection hood 900. The brush roller 940 is positioned along its length to contact the fabric spreading roller 610. A rotating component, a fourth motor 950, is connected to the dust collection hood 900 and is attached to the outer wall of one end along its length. The output shaft of the fourth motor 950 is connected to one end of the brush roller 940. After the fabric spreading roller 610 flattens the fabric, the drive assembly 700 moves the fabric spreading roller 610 above the dust collection hood 900. When the fabric spreading roller 610 is positioned above the dust collection hood 900, the air pump 920 draws air from inside the dust collection hood 900, creating a negative pressure inside the dust collection hood 900. This draws impurities from the surface of the fabric spreading roller 610 into the dust collection hood 900, thereby reducing impurities on the surface of the fabric spreading roller 610 and minimizing secondary contamination of the fabric.

[0044] The implementation principle of a fabric cutting machine with a positioning device according to an embodiment of this application is as follows: During use, the fabric is transported to below the cutter 200. The first cylinder 120 drives the support plate 320 to move downwards in the vertical direction, causing the moving rod 310 and the mounting plate 600 to move downwards along with the support plate 320, thus driving the fabric pulling roller 610 to contact the fabric. After the fabric pulling roller 610 contacts the fabric, the first motor 720 drives the threaded rod 710 to rotate, thereby driving two sliders 730 to slide along the width direction of the fabric and connect to the moving groove 620. The fabric pulling roller 610 moves with the sliders 730, driving the two fabric pulling rollers 610 to move away from each other, thereby flattening the fabric. After the fabric is flattened, the first cylinder 120 continues to drive the support plate 320 to move downward in the vertical direction. The moving rod 310 and the pressure plate 300 follow the support plate 320 to move downward, so that the pressure plate 300 contacts the fabric and presses the fabric, thereby minimizing the occurrence of wrinkles in the fabric when the cutter 200 cuts the fabric and improving the cutting effect.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
