Whether it is mass production of standardized scarves or customized and small-batch specialty products, the cutting equipment needs to have high precision, high efficiency and good fabric adaptability to meet the production needs of different orders. At present, the common scarf fabric cutting equipment on the market mostly adopts traditional mechanical structures, such as manually assisted positioning of the fabric and driving the cutting tool to move by using ordinary mechanical transmission devices.

DETAILED DESCRIPTION

[0018] The following will be described in detail in combination with the accompanying drawings Figure 1 - the accompanying drawings Figure 10 , the present application will be further described in detail.

[0019] The present application provides a kind of based on scarf fabric processing's equal length cutting equipment, including processing table 1, the top of processing table 1 is fixedly connected with two gantries 2, linear module one 3 is installed on the outside of gantry 2, two linear module one 3 are installed on the moving seat of linear module two 4, laser cutting head 5 is installed on the moving seat of linear module two 4, tension leveling mechanism 6 is provided on the outside of processing table 1, sampling mechanism 7 is arranged in the inside of processing table 1, two fixed frames 8 are fixedly connected on the top of processing table 1, conveying belt one 9 is arranged on the similar side of two fixed frames 8, conveying belt two 10 is arranged in the inside of processing table 1, conveying belt two 10 is located below conveying belt one 9, discharge chute 11 is set in the end of processing table 1 close to conveying belt one 9. The pulling flattening mechanism 6 comprises two groups of fixed plates 601 and a compression roller 615, and the two groups of fixed plates 601 are fixedly connected to the outer sides of the processing table 1 respectively, and the number of each group of fixed plates 601 is two. The proximal sides of the two fixed plates 601 are rotatably connected with a reciprocating screw rod 602, and the outer side of the fixed plate 601 is provided with a servo motor 603, and the output end of the servo motor 603 is fixedly connected with one end of the reciprocating screw rod 602.

[0020] The moving speed and position accuracy of the clamping block 606 directly affect the effect of fabric pulling, and the servo motor 603 can ensure that the clamping block 606 moves at a stable and accurate speed by accurately controlling the rotation angle and speed of the reciprocating screw rod 602. For example, when processing fabrics of different thicknesses and materials, the output of the servo motor 603 can be adjusted according to the preset parameters, and for thinner and easily deformed fabrics, the moving speed of the clamping block 606 is reduced to prevent the fabric from being damaged by excessive pulling; for thicker and strong fabrics, the moving speed is appropriately increased to improve the working efficiency. The outer side of the reciprocating screw rod 602 is threadedly connected with a threaded block 604, the top of the threaded block 604 is provided with a pneumatic cylinder 605, the output end of the pneumatic cylinder 605 and the outer side of the threaded block 604 are fixedly connected with a clamping block 606, the top of the processing table 1 is provided with two movable grooves 607, the outer side of the lower clamping block 606 is slidably connected with the inner side of the movable groove 607, and the bottom of the two fixed plates 601 is fixedly connected with a guide rod 619. The inner side of the threaded block 604 is slidably connected with the outer side of the guide rod 619. The outer side of the reciprocating screw rod 602 is threadedly connected with a threaded block 604, the top of the threaded block 604 is provided with a pneumatic cylinder 605, the output end of the pneumatic cylinder 605 and the outer side of the threaded block 604 are fixedly connected with a clamping block 606, the top of the processing table 1 is provided with two movable grooves 607, the outer side of the lower clamping block 606 is slidably connected with the inner side of the movable groove 607, and the bottom of the two fixed plates 601 is fixedly connected with a guide rod 619. The inner side of the threaded block 604 is slidably connected with the outer side of the guide rod 619. The pressure roller 615 plays a key role in the fabric flattening process. With the pulling of the fabric by the clamping blocks 606, the pressure roller 615 is always in close contact with the fabric under the action of the spring 618. The spring 618 has a carefully designed spring constant, which can provide sufficient pressure to effectively smooth out the small wrinkles on the surface of the fabric, and will not cause damage to the fabric due to excessive pressure. When the fabric is locally uneven during the conveying process, the pressure roller 615 will adaptively adjust the pressure under the buffering action of the spring 618, ensuring the overall flatness of the fabric. The outer side of the pressure roller 615 is in close contact with the top of the processing table 1. The sampling mechanism 7 includes a mounting cover 701, a servo motor 702 is mounted on the outside of the mounting cover 701, two cylindrical gears 703 are rotatably connected to the inside of the mounting cover 701, the two cylindrical gears 703 are meshed, the output end of the servo motor 702 is fixedly connected to the outside of one of the cylindrical gears 703, and a discharge port 705 is formed in the inside of the processing table 1. Two rotating plates 704 are rotatably connected to the inside of the discharge port 705, and the rotating shafts on the outside of the rotating plates 704 are fixedly connected to the outside of the cylindrical gears 703.

[0021] The servo motor 702 is started according to the set time interval, drives the two cylindrical gears 703 to rotate, and in turn drives the rotating plates 704 to rotate and open the discharge port 705. The setting of the time interval can be adjusted according to factors such as production batch, fabric quality stability, etc. For example, for a stable quality fabric batch, the sampling interval time can be appropriately extended; for a new batch or a fabric with large quality fluctuations, the sampling interval is shortened, and the sampling frequency is increased. At the discharge port 705, a sensor can also be provided to detect the discharge of the fabric, to ensure that the fabric can be smoothly discharged for quality detection by the staff each time.

[0022] Specifically, first, the staff places one end of the fabric on the top of the processing table 1, passes through the bottom of the pressure roller 615, and then pulls it to the middle of the two clamping blocks 606. Starting the air cylinder 605 can make the upper clamping block 606 move down, so that the two clamping blocks 606 can clamp the fabric, and then starting the servo motor 1 603 drives the reciprocating lead screw 602 to rotate, in turn drives the threaded block 604 to move the two clamping blocks 606, so that one end of the fabric can be pulled to the bottom of the conveyor belt 1, and under the elastic force of the spring 618 in the movable frame 616, the pressure roller 615 can press the fabric tightly to avoid wrinkles. When the laser cutting head 5 is cutting, the two linear modules 1 and 3 and the linear module 4 work together. The linear module 1 is mainly responsible for adjusting the position of the laser cutting head 5 in the direction of the gantry 2, realizing the positioning of the cutting position in the length direction of the fabric; the linear module 4 is fine-tuned in the direction perpendicular to the linear module 1, to ensure the accuracy of the cutting position.

[0023] Through the high-precision control system, the cutting path and size parameters can be pre-set, and the linear module one 3 and the linear module two 4 drive the laser cutting head 5 to move according to the parameters, so as to ensure the position accuracy of each cutting within a very small error range, thereby realizing the equal-length cutting of the scarf fabric. The cut fabric is pushed to the discharge chute 11 by the conveyor belt one 9 and the conveyor belt two 10, and a special fabric collecting container can be arranged below the discharge chute 11. The conveyor belt one 9 and the conveyor belt two 10 cooperate with each other during the fabric conveying and discharging process. The conveyor belt one 9 conveys the cut fabric from the processing area to the discharge chute 11, and the conveyor belt two 10 is located below the conveyor belt one 9, which plays a supporting and pushing role, ensuring that the fabric remains stable during the conveying process and does not deviate or fall due to gravity or other factors.

[0024] At the discharge chute 11, a sensor can be arranged to detect the discharge of the fabric. When the fabric is detected to be accumulated to a certain extent, an automatic cleaning device can be started by the control system to timely transfer the accumulated fabric to the collection container, ensuring the continuous and stable operation of the equipment. The cylinder 605 reciprocates, so that the compression roller 615 can roll the fabric, further improving the flatness of the fabric. A sensor can be arranged outside the clamping block 606 to detect the position of the fabric, or the speed of the servo motor one 603 can be set to correspond to the start of the cylinder 605 to pull and cut the next piece of fabric.

[0025] In addition, the servo motor two 702 can be started at regular intervals to make the two cylindrical gears 703 rotate, so that the two rotating plates 704 rotate to open the channel of the discharge port 705, allowing a piece of fabric to be discharged from the discharge port 705 at regular intervals, which facilitates the staff to conduct sampling inspection.

[0026] Working principle: first, the staff places one end of the fabric on the top of the processing table 1, and passes through the bottom of the compression roller 615, then pulls it to the middle of the two clamping blocks 606, starts the cylinder 605 to make the upper clamping block 606 move down, so that the two clamping blocks 606 can clamp the fabric, then starts the servo motor one 603 to drive the reciprocating screw rod 602 to rotate, and then drives the threaded block 604 to move the two clamping blocks 606, so that one end of the fabric can be pulled to the bottom of the conveyor belt one 9, and the compression roller 615 is pressed tightly under the elastic force of the spring 618 in the movable frame 616, to avoid fabric wrinkles.

[0027] Then start two linear module 3 and linear module 2 4 to adjust the position of the laser cutting head 5, cutting fabric, the fabric will be cut by the conveyor belt 9 and conveyor belt 2 10 push to the discharge chute 11 place discharge, below the discharge chute 11 can be set to collect fabric containers, and the cylinder 605 reciprocating movement, so that the pressure roller 615 can be rolled on the fabric, further improve the flatness of the fabric effect, can be set outside the sensor to detect the position of the fabric, or set the speed of the servo motor 1 603 and the cylinder 605 corresponding relationship to start the next piece of fabric to pull cutting.

[0028] In addition, can be started regularly servo motor 2 702 so that the two cylindrical gear 703 rotation, so that the two rotating plate 704 rotation, open discharge port 705 channel, can be regularly let a piece of fabric from the discharge port 705 discharge, facilitate staff to carry out sampling inspection.

[0029] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, the scope of the present application being defined by the appended claims and their equivalents.
