Description

Technical Field

[0001] This utility model belongs to the field of fabric production technology, and in particular relates to a stretching and shaping device based on fabric cutting. Background Technology

[0002] With the development of the textile industry, my country is at a critical stage of upgrading its textile industry. A large number of emerging textile enterprises are participating in the fierce market competition by relying on technological progress. The focus of the competition is the adjustment of product structure and the improvement of product grade and quality. The fundamental shortcut to improving product grade is to accelerate the pace of technological progress in the weaving industry. Experts have summarized the development trend of textile machinery technology as follows: high speed and high output, high quality and high efficiency are still the goals pursued by the development of textile machinery; efforts should be made to expand the technological performance of machinery to adapt to the changing market demand for textiles.

[0003] However, existing technologies have some problems: In the existing technology, after pulling out a certain length of fabric for stretching and shaping, the fabric is pressed on one side and then cut. However, when the cutter cuts, because there is pressure on one side and no pressure on the other side, the cut fabric will shift or twist during the cutting process, which will affect the cutting accuracy and make the cut messy and uneven. Therefore, we propose a stretching and shaping device based on fabric cutting. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a stretching and shaping device based on fabric cutting. By setting a connecting cylinder and a pressure rod on the cutter, pressure is applied to both sides during cutting, so that the fabric cut position always maintains pressure balance, thereby ensuring cutting accuracy and achieving a smooth cut.

[0005] This utility model is implemented as follows: a stretching and shaping device based on fabric cutting includes a frame, a roller holder on the frame, a material placing roller rotatably connected to the roller holder, a worktable on the frame, a support plate fixedly connected to the side of the worktable, a heating element on the frame, a stretching element on the frame, a cutting element on the worktable, a cutting blade on the cutting element, a slide rail on the support plate, a sliding rod on the slide rail, and a gripper on the sliding rod.

[0006] Optionally, the air-heating assembly includes an air-heating box, which is fixedly connected to the frame. A hot air blower is installed on the air-heating box, and a control panel is installed on the hot air blower. Exhaust pipes are installed on both sides of the hot air blower. An air outlet is installed inside the air-heating box, and the air outlet is connected to the exhaust pipe. A first guide roller is installed on the air-heating box, and a dustproof plate is installed on the air-heating box.

[0007] Optionally, the stretching assembly includes a hot press roller, which is rotatably connected to the air-heated box. An clearance groove is provided on the support plate, and a pressure telescopic rod is fixedly connected inside the clearance groove. A pressure roller is rotatably connected to the output end of the pressure telescopic rod. Two second guide rollers are rotatably connected to the support plate, and the two second guide rollers are symmetrically distributed on both sides of the pressure roller.

[0008] Optionally, the cutting assembly includes a boss and a bracket, both of which are fixedly connected to the worktable. A cylinder is fixedly connected to the bracket, and a pressure plate is fixedly connected to the output end of the cylinder. A rubber texture is fixedly connected to the lower end of the pressure plate.

[0009] Optionally, a motor is fixedly mounted on the bracket, a lead screw is fixedly connected to the output end of the motor, the lead screw is rotatably connected to the bracket, a slider is rotatably connected to the lead screw, the slider is slidably connected to the bracket, an electronic telescopic rod is fixedly connected to the lower end of the slider, and a cutting blade is fixedly connected to the output end of the electronic telescopic rod.

[0010] Optionally, a connecting plate is fixedly connected to the cutting blade, a connecting cylinder is fixedly connected to the lower end of the connecting plate, a pressure rod is slidably connected inside the connecting cylinder, a guide wheel is rotatably connected to the lower end of the pressure rod, a spring is provided inside the connecting cylinder, one end of the spring is fixedly connected to the connecting cylinder, and the other end of the spring is fixedly connected to the pressure rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By incorporating a connecting plate, connecting cylinder, pressure rod, guide wheel, and spring into the cutting blade, the pressure plate presses down on one side of the fabric during cutting. As the cutting blade presses down, the connecting plate is simultaneously pressed down, and the guide wheel contacts the fabric before the cutting blade, causing the pressure rod to retract the connecting cylinder and compress the spring. This ensures that the guide wheel always presses the fabric firmly. When the cutting blade moves to cut, it simultaneously drives the guide wheel to press the fabric, ensuring that the pressure on both sides of the fabric is always balanced when the cutting blade contacts the fabric. This achieves sufficient precision in the fabric cut and improves the overall efficiency and quality of fabric cutting and stretching.

[0013] 2. By setting pressure rollers, the elastic telescopic rod drives the pressure rollers to continuously press down, applying uniform pressure to the fabric, making it smoother during the stretching and shaping process, reducing wrinkles and wavy deformation, thereby improving the shaping effect of the fabric, making the fibers in the fabric denser, reducing burrs, bubbles and defects, and enhancing the density, strength and surface quality of the fabric.

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] like Figures 1 to 8As shown in the figure, the present invention provides a stretching and shaping device based on fabric cutting, including a frame 1, a roller holder 11 on the frame 1, a material placing roller 12 rotatably connected to the roller holder 11, a worktable 13 on the frame 1, a support plate 14 fixedly connected to the side of the worktable 13, a heat exchanger 2 on the frame 1, a stretching assembly 3 on the frame 1, a cutting assembly 4 on the worktable 13, a cutting blade 5 on the cutting assembly 4, a slide rail 15 on the support plate 14, a slide rod 16 on the slide rail 15, and a gripper 17 on the slide rod 16.

[0026] Furthermore, the stable conveying of the fabric is achieved through the cooperation of the feeding roller 12 and the worktable 13; the air-heating component 2 effectively preheats and sets the fabric, improving its quality; the stretching component 3 ensures that the fabric maintains uniform tension during stretching, avoiding deformation; the precise cooperation between the cutting component 4 and the gripper 17 enables efficient and accurate cutting of the fabric, while the design of the slide rail 15 and the slide bar 16 enhances the flexibility and convenience of operation, thus improving the overall efficiency and quality of fabric cutting and stretching.

[0027] Specifically, the air-heating assembly 2 includes an air-heating box 21, which is fixedly connected to the frame 1. A hot air blower 22 is installed on the air-heating box 21, and a control panel 23 is installed on the hot air blower 22. Exhaust pipes 24 are installed on both sides of the hot air blower 22. An air outlet 25 is installed inside the air-heating box 21, which is connected to the exhaust pipe 24. A first guide roller 26 is installed on the air-heating box 21, and a dustproof plate 27 is installed on the air-heating box 21.

[0028] Furthermore, the hot air blower 22 precisely controls the temperature and wind speed through the control panel 23, and has multiple air outlets 25 that are evenly distributed to ensure that the fabric is heated evenly and efficiently shaped. The first guide roller 26 guides the fabric smoothly through the hot air zone, while the dustproof plate 27 effectively blocks external dust and protects the fabric from contamination. This not only improves the fabric sizing effect but also ensures a clean and efficient working environment, providing strong support for fabric cutting and stretching.

[0029] Specifically, the tensioning assembly 3 includes a hot press roller 31, which is rotatably connected to the air-heat box 21. A clearance groove 32 is provided on the support plate 14. A pressure telescopic rod 33 is fixedly connected inside the clearance groove 32. A pressure roller 34 is rotatably connected to the output end of the pressure telescopic rod 33. A second guide roller 35 is rotatably connected to the support plate 14. There are two second guide rollers 35, which are symmetrically distributed on both sides of the pressure roller 34.

[0030] Furthermore, by setting pressure roller 34, the elastic telescopic rod drives pressure roller 34 to continuously press down, applying uniform pressure to the fabric, making it smoother during the stretching and shaping process, reducing wrinkles and deformation, thereby improving the shaping effect of the fabric, and making the fibers in the fabric more compact, reducing burrs, bubbles and defects, and enhancing the density, strength and surface quality of the fabric.

[0031] Specifically, the cutting component 4 includes a boss 41 and a bracket 42. Both the boss 41 and the bracket 42 are fixedly connected to the worktable 13. A cylinder 43 is fixedly connected to the bracket 42. A pressure plate 44 is fixedly connected to the output end of the cylinder 43. A rubber texture 45 is fixedly connected to the lower end of the pressure plate 44.

[0032] Furthermore, the cutting component 4 is securely connected to the bracket 42 via the boss 41, ensuring the stability of the cutting operation; the cylinder 43 serves as a power source, and the pressure plate 44 connected to its output end can precisely control the downward pressure to achieve stable pressing of the fabric; the rubber texture 45 set at the lower end of the pressure plate 44 not only increases the friction between the pressure plate and the fabric to prevent the fabric from sliding during cutting, but also protects the fabric surface from damage due to its softness.

[0033] Specifically, a motor 46 is fixedly installed on the bracket 42, a lead screw 47 is fixedly connected to the output end of the motor 46, the lead screw 47 is rotatably connected to the bracket 42, a slider 48 is rotatably connected to the lead screw 47, the slider 48 is slidably connected to the bracket 42, an electronic telescopic rod 49 is fixedly connected to the lower end of the slider 48, and a cutting blade 5 is fixedly connected to the output end of the electronic telescopic rod 49.

[0034] Furthermore, the motor 46 drives the lead screw 47 to rotate, and through the threaded engagement between the slider 48 and the lead screw 47, the slider 48 achieves precise sliding on the bracket 42, thereby ensuring the precise movement of the cutter 5 in the horizontal direction. The introduction of the electronic telescopic rod 49 further enables the flexible adjustment of the cutter 5 in the vertical direction, making the cutting process more flexible and versatile, and able to meet the cutting needs of fabrics of different sizes and shapes. This not only improves the accuracy and efficiency of cutting, but also enhances the adaptability and flexibility of the cutting component 4.

[0035] Specifically, a connecting plate 51 is fixedly connected to the cutter 5, a connecting cylinder 52 is fixedly connected to the lower end of the connecting plate 51, a pressure rod 53 is slidably connected inside the connecting cylinder 52, a guide wheel 54 is rotatably connected to the lower end of the pressure rod 53, a spring 55 is provided inside the connecting cylinder 52, one end of the spring 55 is fixedly connected to the connecting cylinder 52, and the other end of the spring 55 is fixedly connected to the pressure rod 53.

[0036] Working principle: During cutting, the pressure plate 44 presses down on one side of the fabric of the cutter 5. When the cutter 5 presses down, it simultaneously drives the connecting plate 51 to press down. The guide wheel 54 contacts the fabric before the cutter 5, driving the pressure rod 53 to retract the connecting cylinder 52 and compress the spring 55, so that the guide wheel 54 always presses the fabric. When the cutter 5 moves to cut, it simultaneously drives the guide wheel 54 to press the fabric, so that when the cutter 5 contacts the fabric, the pressure on both sides of the fabric is always balanced, so that the fabric cut maintains sufficient precision, and the overall efficiency and quality of fabric cutting and stretching are improved.
