Description

Technical Field

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

[0002] Ice silk fabric is a type of fabric primarily made of synthetic fibers (such as polyester, nylon, or spandex), processed through special weaving techniques and finishing treatments to achieve a smooth surface, a cool feel, and a softness and luster similar to silk. During processing, ice silk fabric requires cutting to separate large pieces of raw fabric into the required components according to the dimensions and shapes outlined in the design drawings. This ensures accurate dimensions and neat edges during subsequent sewing and splicing, thereby improving product quality.

[0003] In existing technologies, ice silk fabric has an extremely smooth texture and strong drape. Currently, it relies on operators to manually lay and position the fabric. When laying the ice silk fabric, it is difficult to maintain uniform tension when applied manually. It is very easy to unintentionally stretch the ice silk fabric or leave fine wrinkles. Subsequently, the ice silk fabric is very prone to slippage or wrinkling on the cutting platform, which will cause the ice silk fabric to shift during the cutting process and cause deviations in the size of the cut pieces. Therefore, we propose a fabric cutting machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fabric cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fabric cutting machine includes a vibrating knife cutting machine body. A cylinder is fixedly connected inside the vibrating knife cutting machine body. A U-shaped plate is fixedly connected to the outer wall of the cylinder's output end. A rotating shaft is rotatably embedded in the outer wall of the U-shaped plate. A drive shaft is rotatably connected inside the vibrating knife cutting machine body. Rubber sleeves are fixedly fitted onto the outer walls of both the rotating shaft and the drive shaft. A servo motor is fixedly connected inside the vibrating knife cutting machine body. One end of the servo motor's output shaft is fixedly connected to the outer wall of the drive shaft. Two ear plates are fixedly connected to the outer wall of the vibrating knife cutting machine body. A limiting component is provided on the outer wall of the vibrating knife cutting machine body.

[0007] Preferably, the limiting component includes a stepper motor, a device frame is fixedly connected to the outer wall of the vibrating knife cutting machine body, the inside of the device frame is fixedly connected to the outer wall of the stepper motor, an extrusion plate is rotatably connected between the two ear plates, one end of the output shaft of the stepper motor is fixedly connected to the outer wall of the extrusion plate, a rubber strip is fixedly connected to the outer wall of the extrusion plate, and the extrusion plate, in conjunction with the rubber strip, extrudes one end of the fabric to the outer side of the vibrating knife cutting machine body.

[0008] Preferably, the outer wall of the U-shaped plate is fixedly connected to two guide rods, and the outer wall of each guide rod is slidably fitted with a guide sleeve. One end of each guide sleeve is fixedly connected to the inner wall of the vibrating knife cutting machine body. The guide rods and guide sleeves cooperate to form a guiding structure, ensuring that the U-shaped plate always moves in a straight line when it moves with the cylinder output end.

[0009] Preferably, a vibrating cutter head is installed on the top of the vibrating cutter body. The vibrating cutter head achieves efficient cutting of the fabric through high-speed vibration and is moved by an external linear motor of the vibrating cutter body.

[0010] Preferably, one of the ear plates and the outer wall of the device frame are provided with a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the stepper motor output shaft.

[0011] Preferably, the top of the vibrating knife cutting machine body is hinged with an opening and closing door, and a handle is fixedly connected to the outer wall of the opening and closing door.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses a stepper motor to drive the extrusion plate to rotate, utilizing the good friction between the rubber strip and the fabric to press and fix the fabric end to the outer side of the cutting machine, preventing end displacement. At the other end, a cylinder pushes the U-shaped plate to move, so that the rubber sleeve on the rotating shaft and the drive shaft together press the fabric surface, forming a bidirectional limit to prevent the ice silk fabric from slipping during the cutting process. A servo motor drives the drive shaft to rotate, automatically feeding the remaining waste fabric downwards, realizing unified waste recycling and creating favorable conditions for the continuous development of the next processing stage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a fabric cutting machine is disclosed, comprising a vibrating knife cutting machine body 1 (CHSD1625). A vibrating knife head 2 is mounted on the top of the vibrating knife cutting machine body 1 (CHSD1625). The vibrating knife head 2 achieves efficient cutting of the fabric through high-speed vibration. A cylinder 3 is fixedly connected inside the vibrating knife cutting machine body 1 (CHSD1625). The cylinder 3 can quickly drive the rotating shaft 5 to approach or move away from the drive shaft 6, thereby achieving rapid pressing or releasing of the fabric. The drive shaft 6 and the rotating shaft 5 are at the same horizontal position. After the two rubber sleeves 7 are squeezed together, the drive shaft 6 cannot rotate due to the self-locking of the servo motor 8. A U-shaped plate 4 is fixedly connected to the outer wall of the output end of the cylinder 3. The rotating shaft 5 is rotatably embedded in the outer wall of the U-shaped plate 4. The drive shaft 6 is rotatably connected inside the vibrating knife cutting machine body 1 (CHSD1625) through existing roller bearings. Rubber sleeves 7 are fixedly fitted on the outer walls of both the rotating shaft 5 and the drive shaft 6. The rubber sleeves 7 have good elasticity and coefficient of friction.

[0021] A servo motor 8 is fixedly connected inside the vibrating knife cutting machine body 1 (CHSD1625). One end of the output shaft of the servo motor 8 is fixedly connected to the outer wall of the drive shaft 6. Two guide rods 9 are fixedly connected to the outer wall of the U-shaped plate 4. Guide sleeves 10 are slidably sleeved on the outer wall of each of the two guide rods 9. One end of each guide sleeve 10 is fixedly connected to the inner wall of the vibrating knife cutting machine body 1 (CHSD1625). The guide rods 9 and guide sleeves 10 cooperate to form a guide structure, which can limit the movement trajectory of the U-shaped plate 4 and ensure that the U-shaped plate 4 always moves in a straight line when it moves with the output end of the cylinder 3.

[0022] Two ear plates 11 are fixedly connected to the outer wall of the vibrating knife cutting machine body 1 (CHSD1625). The top of the vibrating knife cutting machine body 1 (CHSD1625) is hinged with an opening and closing door 15. A handle 16 is fixedly connected to the outer wall of the opening and closing door 15. The opening and closing door 15 prevents personnel from touching the drive shaft 6 and the rotating shaft 5.

[0023] The outer wall of the vibrating knife cutting machine body 1 (CHSD1625) is provided with a limiting component, which includes a stepper motor 12. One of the ear plates 11 and the outer wall of the equipment frame are both provided with round holes. The inner wall of the round holes is rotatably connected to the outer wall of the output shaft of the stepper motor 12. The equipment frame is fixedly connected to the outer wall of the vibrating knife cutting machine body 1 (CHSD1625). The inside of the equipment frame is fixedly connected to the outer wall of the stepper motor 12. The outer wall of the equipment frame is provided with multiple heat dissipation holes for heat dissipation of the stepper motor 12. An extrusion plate 13 is rotatably connected between the two ear plates 11 through an existing bearing. One end of the output shaft of the stepper motor 12 is fixedly connected to the outer wall of the extrusion plate 13 and rotates under the drive of the stepper motor 12. The extrusion plate 13, together with the rubber strip 14, extrudes one end of the fabric to the outer side of the vibrating knife cutting machine body 1 (CHSD1625) to achieve reliable fixation of the fabric end. The rubber strip 14 is fixedly connected to the outer wall of the extrusion plate 13.

[0024] Add existing electromagnetic brakes or mechanical brake pads to the output shafts of servo motor 8 and stepper motor 12 to achieve hard self-locking.

[0025] Working principle: When in use, the ice silk fabric to be cut is laid flat on the working surface of the vibrating knife cutting machine body 1. The two ends of the ice silk fabric are respectively placed on the extrusion plate 13 and the rubber sleeve 7. The stepper motor 12 drives the extrusion plate 13 to rotate. The rubber strip 14 on the outer wall of the extrusion plate 13 contacts the ice silk fabric with good friction, and extrudes one end of the ice silk fabric to the outer side of the vibrating knife cutting machine body 1, thus fixing the position of one end of the ice silk fabric.

[0026] At the same time, the output end of cylinder 3 pushes the U-shaped plate 4 to move, so that the rubber sleeve 7 on the outer wall of the rotating shaft 5 cooperates with the rubber sleeve 7 on the drive shaft 6 to press the surface of the ice silk fabric, and fix the other end of the ice silk fabric in position. The servo motor 8 runs to drive the drive shaft 6 to rotate, thereby straightening the ice silk fabric through the squeezing and rotational force of the two rubber sleeves 7, ensuring its flatness in subsequent processing.

[0027] The vibrating head 2 at the top of the vibrating cutter body 1 is activated and vibrates at high speed according to the preset cutting path to cut the fixed ice silk fabric. After the cutting is completed, the cut ice silk fabric parts are collected. Then, the stepper motor 12 is driven to reset and drive the rubber strip 14 away from the end of the ice silk fabric. The servo motor 8 drives the drive shaft 6 to rotate and send the remaining waste ice silk fabric downward. It can be placed in an existing frame for collection. The waste ice silk fabric will then be processed and enter the next processing stage.

[0028] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the servo motor 8 and the stepper motor 12 to facilitate the control of the overall operation.
