[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] like Figures 1-7 As shown, this utility model proposes an automatic measuring and cutting device for a multi-needle quilting machine, including a frame 1. The frame 1 is located at the tail of the multi-needle quilting machine. The frame 1 includes two symmetrically arranged side plates 10. Multiple conveying rollers 2 are provided at one end of the frame 1 near the multi-needle quilting machine. Figure 2As shown, multiple conveyor rollers 2 are arranged in a staggered manner, and the conveyor rollers 2 are rotatably positioned between two side plates 10. A guide roller 3 is provided at the top of the other end of the frame 1, and the guide roller 3 is arranged axially parallel to the conveyor rollers 2. This application includes a power unit for driving the conveyor rollers 2 and guide rollers 3 to rotate, serving as the driving force for fabric conveying. The power unit can be a motor as used in the prior art, or a motor combined with a belt and drive pulley to provide rotational power for all conveyor rollers 2 and guide rollers 3.
[0024] In this application, a meter counter 4 is provided above the guide roller 3, such as... Figure 1 and Figure 2 As shown, a crossbar 12 is provided at the top of the frame 1, and the measuring wheel is fixedly mounted on the crossbar 12. The measuring device 4 can calculate the length of the fabric it passes through. This measuring device 4 is existing technology, employing automated components and a structure that combines a rotary encoder and a measuring wheel. The measuring wheel is mounted on the input rotor of the rotary encoder. The measuring wheel presses the fabric against the guide roller 3, and the transmission is achieved through the contact between the measuring wheel and the fabric, maintaining a consistent speed between them. The rotation of the measuring wheel drives the rotor of the connected rotary encoder to rotate, converting the mechanical rotation into a series of electrical pulse signals. These signals are then processed to obtain the length of the fabric, thus achieving the effect of measuring the length of the fabric.
[0025] In this application, if Figure 2 As shown, a fixing plate 5 is provided below the guide roller 3, and the fixing plate 5 is fixedly disposed between two side plates 10. A cutting groove 50 is provided through the fixing plate 5 along its length. An electric slide rail 7 is slidably disposed on one side of the fixing plate 5. The electric slide rail 7 is arranged parallel to the fixing plate 5. A fabric clamping plate 6 is fixedly disposed on the side of the electric slide rail 7 near the fixing plate 5. Both ends of the fabric clamping plate 6 are provided with end plates 61. The end plates 61 are fixedly connected to the ends of the electric slide rail 7 by bolts, so that the fabric clamping plate 6 and the electric slide rail 7 are connected as one unit. At the same time, each end plate 61 is provided with an end block 62. The side plates 10 of the frame 1 are also provided with corresponding rails 11 that are slidably connected to the end blocks 62, so that the fabric clamping plate 6 and the electric slide rail 7 can slide synchronously. The fabric clamping plate 6 is provided with a through groove 60 along its length, which is arranged opposite to the cutting groove 50 and on the same horizontal plane. A cutting scissor is slidably mounted on the electric slide rail 7. The outer cutting edge of the cutting scissor passes through the through groove 60 and is located between the fixed plate 5 and the fabric clamping plate 6. Figure 5As shown, a slider 19 is slidably mounted on the electric slide rail 7. The electric slide rail 7 adopts existing technology, and the electric slide rail 7 drives the slider 19 to slide back and forth. A mounting plate 20 is provided on the side of the slider 19 near the fabric clamping plate 6. The cutting shears are located below the mounting plate 20, and the cutting shears are disc cutters 9. A stepper motor 15 is provided above the mounting plate 20 to drive the disc cutter 9 to rotate at high speed. The stepper motor 15 driving the disc cutter 9 to rotate at high speed for cutting is existing technology. The cutting outer edge of the disc cutter 9 passes through the through groove 60 and is located between the fixed plate 5 and the fabric clamping plate 6. In this application, a cylinder 8 is also provided on the side of the electric slide rail 7 away from the fabric clamping plate 6 to push it closer to or away from the fixed plate 5. The cylinder 8 is fixed on the frame 1, and the end of the piston rod of the cylinder 8 is fixedly connected to the electric slide rail 7.
[0026] In this application, the frame 1 is located at the tail of the multi-needle quilting machine. After the fabric is quilted by the multi-needle quilting machine, it enters the conveyor roller 2 on the frame 1 and is conveyed to the guide roller by the conveyor roller 2. When the fabric passes through the guide roller, the length of the fabric is measured by the meter counter 4. Then, it hangs down between the fixed plate 5 and the clamping plate 6. When the fabric reaches the set length, the cylinder 8 pushes the electric slide rail 7 and the clamping plate 6 to move closer to the fixed plate 5, so that the clamping plate 6 and the fixed plate 5 tightly clamp the fabric. Then, the stepper motor 15 drives the disc cutter 9 to rotate at high speed, and the electric slide rail 7 drives the slider 19 to move quickly, so that the disc cutter 9 quickly cuts the fabric along the length direction of the through groove 60. When the circular cutter 9 moves from one end of the electric slide rail 7 to the other, the fabric cutting is complete. At this time, the cylinder 8 drives the electric slide rail 7 and the fabric clamping plate 6 to move away from the fixed plate 5, and then the fabric is released. The cut fabric falls naturally, and the remaining fabric continues to repeat the above operation for the next cutting. The fabric is clamped by the fabric clamping plate 6 and the fixed plate 5 before cutting to ensure the stability of the fabric during the cutting process and avoid cutting off-center.
[0027] Furthermore, to avoid the danger caused by the exposed disc cutter 9, a protective component is provided on the outside of the disc cutter 9 in this application. For example... Figures 3-7As shown, the protective assembly includes a protective cover 13 and an adjustment section. The protective cover 13 is a hollow cuboid structure with openings at both ends. A square through-slot 130 is provided on the top of the protective cover 13, and the protective cover 13 is slidably connected to the mounting plate 20. The disc cutter 9 is located inside the protective cover 13. One end of the protective cover 13 near the fabric clamping plate 6 passes through the through-slot 60 and is flush with the outer cutting edge of the disc cutter 9 (wherein the open end of the protective cover 13 is flush with the outer cutting edge of the disc cutter 9). The protective cover 13 includes a top layer, side walls, and a bottom layer. The side walls and top layer are an integral structure, while the bottom layer is bolted to the side walls, so that the protective cover 13 can be easily placed over the disc cutter 9 during installation. In addition, the connection between the disc cutter 9 and the mounting plate 20 and the stepper motor 15 is located at the square through-slot 130, and the opening area of the square through-slot 130 is relatively large, so the setting of the protective cover 13 will not affect the sliding of the protective cover 13.
[0028] like Figures 3-7 As shown, the adjusting part is used to control the sliding of the protective cover 13 to expose or cover the cutting outer edge of the disc cutter 9. Wherein... Figure 6 As shown, the top of the protective cover 13 is provided with a slide bar 14, and the bottom of the mounting plate 20 is provided with a slide groove 200. The sliding direction of the slide groove 200 is perpendicular to the sliding direction of the electric slide rail 7, and the slide bar 14 is slidably connected to the slide groove 200. The adjustment part includes a spring 16, a protrusion 17, and a slide post 18. The spring 16 is located at the end of the slide groove 200 away from the fabric clamping plate 6, and the two ends of the spring 16 are fixedly connected to the end of the slide groove 200 and the end of the slide bar 14, respectively. Figure 5 As shown, the sliding column 18 is fixedly installed at the bottom of the protective cover 13; the protruding strip 17 is installed along the length of the fabric clamping plate 6 on the side of the fabric clamping plate 6 near the electric slide rail 7, and the protruding strip 17 is located below the through groove 60, as shown. Figure 7 As shown, both ends of the protruding strip 17 are provided with sloping transition portions 170, and the sliding column 18 is slidably connected to the protruding strip 17. There is a distance between the end of the protruding strip 17 and the corresponding end of the fabric clamping plate 6; the protruding strip 17 does not extend to both ends of the fabric clamping plate 6. When the disc cutter 9 is not cutting, the disc cutter 9 is located at the end of the fabric clamping plate 6. At this time, the protective cover 13 is flush with the outer cutting edge of the disc cutter 9, that is, the protective cover 13 completely covers the disc cutter 9. When the disc cutter 9 cuts the fabric, it moves from one end of the fabric clamping plate 6 to the other. When the disc cutter 9 moves to the protruding strip 17, as... Figure 5 As shown, the protruding strip 17 pushes the sliding column 18 away from the fabric clamping plate 6. At this time, the sliding column 18 drives the protective cover 13 to move a small distance away from the fabric clamping plate 6, and the protective cover 13 can then expose the cutting edge of the disc cutter 9, allowing the disc cutter 9 to cut the fabric. For example... Figure 7As shown, when the disc cutter 9 is located at the end of the fabric clamping plate 6, the corresponding end of the protrusion 17 extends to the corresponding position of the slide post 18. That is, once the disc cutter 9 starts to move, the protrusion 17 can immediately drive the slide post 18 to move, so that the protective cover 13 is exposed on the outer edge of the disc cutter 9.
[0029] In this application, by providing a protective cover 13 on the outside of the disc cutter 9, the disc cutter 9 can be completely covered inside the protective cover 13 when it is not in operation, thus preventing accidental injury to workers. When the disc cutter 9 is in operation, the outer edge of the cutting edge can be exposed, and at the same time, it is engaged by the cutting groove 50 on the fixing plate 5, so that the outer edge of the cutting edge of the disc cutter 9 will not be exposed.
[0030] The above description is only a preferred embodiment of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
