Description

Technical Field

[0001] This utility model belongs to the field of warp knitting technology in the textile industry, specifically, it relates to a fully automated splitting machine. Background Technology

[0002] Splitting machines are widely used in the warp knitting machine industry both domestically and internationally. These machines cut warp-knitted products in half, ensuring both sides have the same pile length. A splitting machine is a textile device used to cut double-layered fabrics into single-sided pile layers. It is mainly used in the processing of cylindrical fabrics such as blankets and knitted fabrics. Its core function is to cut and flatten the fabric through mechanical structure, improving the fabric's softness, moisture absorption, and ease of subsequent processing.

[0003] Traditionally, the operation of a splitting machine involves operators manually collecting the burr lengths of side A and side B, and then manually comparing the burr lengths of side A and side B. When the burr lengths of side A and side B are not equal and there is a deviation, the operator manually adjusts the gantry to move forward (or backward) to correct the deviation. This requires high technical skills from the operators, is labor-intensive, and makes it difficult to automate the splitting process.

[0004] There are currently no effective solutions to the problems in the relevant technologies.

[0005] Therefore, in order to solve the above problems, this utility model provides a fully automated web cutting machine. Utility Model Content

[0006] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a fully automated web cutting machine.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A fully automated splitting machine includes a splitting machine frame and a double-layer fabric. The splitting machine frame is internally equipped with a first feed guide roller, a spreading roller, a feed traction roller, and a second feed guide roller for guiding, widening, and pulling the double-layer fabric. A belt cutter is installed above the inside of the splitting machine frame to perform the splitting operation on the double-layer fabric, splitting it into A-side fabric and B-side fabric. Two sets of gantry bars for controlling the pile length of the A-side and B-side fabrics are installed inside the splitting machine frame, distributed on both sides of the belt cutter. An A-side fabric density measuring instrument and a B-side fabric density measuring instrument are installed inside the splitting machine frame for detecting the pile length of the A-side and B-side fabrics. Two sets of adjustment components for adjusting the position of the gantry bars are also installed inside the splitting machine frame.

[0009] Furthermore, one side of the slitting machine frame is provided with a fabric inlet for the double-layer fabric to enter, and the opposite sides of the slitting machine frame are also provided with outlets for the A-side fabric and B-side fabric after slitting to flow out.

[0010] Furthermore, the first fabric feed guide roller is mounted below the frame of the splitting machine, the widening roller is positioned to the upper left of the first fabric feed guide roller, two sets of fabric feed traction rollers are provided, both positioned above the widening roller, and the second fabric feed guide roller is positioned above the traction roller.

[0011] Furthermore, the right side of the inside of the slitting machine frame is equipped with a first A-side guide roller, an A-side traction roller, and a second A-side guide roller. The first A-side guide roller is located inside the upper part of the slitting machine frame and is located to the right of the blade. The A-side traction roller is located below the first A-side guide roller and below the A-side fabric density measuring instrument. The second A-side guide roller is located below the A-side traction roller.

[0012] Furthermore, the left side of the interior of the slitting machine frame is equipped with a first B-side guide roller, a B-side traction roller, and a second B-side guide roller. The first B-side guide roller is located inside the upper part of the slitting machine frame and to the left of the blade. The B-side traction roller is located below the first B-side guide roller and below the B-side fabric density measuring instrument. The second B-side guide roller is located below the B-side traction roller.

[0013] Furthermore, the adjustment assembly includes a slide rail mounting base, a slide rail, a slider, a motor base, a servo motor, and a lead screw;

[0014] The slide rail mounting base is assembled on the frame of the splitting machine. The slide rail and the motor base are both assembled on the slide rail mounting base. A slider is installed on the slide rail and the slider is connected to the gantry. A servo motor is fixedly installed on the motor base. The output end of the servo motor is connected to one end of a lead screw through a coupling. The lead screw is threadedly connected to the slider.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, the device is a continuous automated process with "double-layer fabric input - pretreatment - cutting - quality control - output" as the main line. The whole process relies on the linkage of various structures to achieve efficient and high-precision cutting.

[0017] 2. In this invention, the density of the A-side fabric and the B-side fabric after cutting is monitored in real time using an A-side fabric density measuring instrument and a B-side fabric density measuring instrument. The A-side fabric density measuring instrument and the B-side fabric density measuring instrument operate on the same principle, both using a low-energy X-ray emitter to emit X-rays that penetrate the fabric. After the X-rays penetrate the fabric, they are received by an X-ray sensor. The strength of the received signal reflects the density of the fabric. As long as the densities of the A-side fabric and the B-side fabric are the same, the pile height of the A-side fabric and the B-side fabric will be the same. When the pile length of the A-side fabric is greater than that of the B-side fabric, the adjustment component of the A-side fabric area will move the gantry at that position toward the B-side fabric area. Similarly, when the pile length of the B-side fabric is greater than that of the A-side fabric, the adjustment component of the B-side fabric area will move the gantry at that position toward the A-side fabric area, thereby adjusting the pile length deviation to make the pile lengths of the A and B sides the same. This method can achieve automated adjustment, reduce the labor intensity of workers, and improve efficiency. Attached Figure Description

[0022] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0023] Please see Figure 1According to an embodiment of the present invention, a fully automated fabric splitting machine includes a splitting machine frame 1 and a double-layer fabric 16. The splitting machine frame 1 is internally equipped with a first feed guide roller 3, a spreading roller 4, a feed traction roller 5, and a second feed guide roller 6 for guiding, spreading, and pulling the double-layer fabric 16. The first feed guide roller 3 is mounted below the splitting machine frame 1 and initially guides the fabric in. The spreading roller 4 is located to the upper left of the first feed guide roller 3 and is used to flatten the fabric, eliminate wrinkles, and prevent deformation during splitting. Two sets of feed traction rollers 5 are provided, both positioned above the spreading roller 4, and provide stable traction force to control the fabric feed speed. To prevent slippage or deviation, the second feed guide roller 6 is positioned above the traction roller 5. The second feed guide roller 6 ensures a smooth fabric transition. The cooperation of the first feed guide roller 3, the widening roller 4, the feed traction roller 5, and the second feed guide roller 6 prepares the fabric for the cutting process, ensuring its flatness and freedom from uneven tension. Inside the upper part of the slitting machine frame 1, a blade 7 is installed to cut the double-layer fabric 16. The double-layer fabric 16 is cut by the blade 7 into A-side fabric 17 and B-side fabric 18. The blade 7 is the core tool of the slitting machine, commonly used in the textile industry to separate double-layer fabrics. The cutting with the blade 7 ensures precise and efficient cutting, reducing fabric damage. Inside the slitting machine frame 1, two sets of control... The gantry 22 for measuring the pile length of fabric A 17 and fabric B 18 has two sets of gantry 22 distributed on both sides of the blade 7. The two sets of gantry 22 directly contact fabric A 17 and fabric B 18 to ensure clean cutting edges. The frame 1 of the splitting machine is equipped with fabric A density measuring instruments 9 and 13 for measuring the pile length of fabric A 17 and fabric B 18. Both fabric A density measuring instruments 9 and 13 are electrically connected to the PLC controller on the splitting machine (the PLC controller is not shown in the diagram; it is a mature product in existing technology, and its specific structure and working principle will not be described here). 13. Real-time monitoring of the density of fabric A 17 and fabric B 18 after cutting. The principle of fabric A density measuring instrument 9 and fabric B density measuring instrument 13 is the same. They both use a low-energy X-ray emitter to emit X-rays that penetrate the fabric. After the X-rays penetrate the fabric, they are received by the X-ray sensor. The strength of the received signal reflects the size of the fabric density. As long as the density of fabric A 17 and fabric B 18 is the same, the pile height of fabric A 17 and fabric B 18 will be the same. The frame 1 of the cutting machine is also equipped with two sets of adjustment components for adjusting the position of the gantry 22. The adjustment components can not only realize automatic adjustment according to the data detected by the measuring instrument, but also adapt to different fabric types and improve the cutting consistency.

[0024] Please see Figure 1The frame 1 of the slitting machine is provided with a fabric inlet 2 on one side for the double-layer fabric 16 to enter. The opposite sides of the frame 1 of the slitting machine are also provided with outlets for the A-side fabric 17 and B-side fabric 18 to flow out after slitting. The A-side fabric 17 and B-side fabric 18 flow out from different outlets to achieve diversion operation.

[0025] Please see Figure 1 The right side of the inside of the slitting machine frame 1 is equipped with a first A-side guide roller 8, an A-side traction roller 10, and a second A-side guide roller 11. The first A-side guide roller 8 is located inside the upper part of the slitting machine frame 1 and to the right of the blade 7. The A-side traction roller 10 is located below the first A-side guide roller 8 and below the A-side fabric density measuring instrument 9. The second A-side guide roller 11 is located below the A-side traction roller 10. The first A-side guide roller 8 and the second A-side guide roller 11 ensure smooth output of the A-side fabric 17 and avoid tangling. The A-side traction roller 10 provides output power. The combination of the first A-side guide roller 8, the A-side traction roller 10, and the second A-side guide roller 11 realizes the guiding and traction operation of the slitting A-side fabric 17.

[0026] Please see Figure 1 The left side of the interior of the slitting machine frame 1 is equipped with a first B-side guide roller 12, a B-side traction roller 14, and a second B-side guide roller 15. The first B-side guide roller 12 is located inside the upper part of the slitting machine frame 1 and to the left of the blade 7. The B-side traction roller 14 is located below the first B-side guide roller 12 and below the B-side fabric density measuring instrument 13. The second B-side guide roller 15 is located below the B-side traction roller 14. The first B-side guide roller 12 and the second B-side guide roller 15 ensure smooth output of the B-side fabric 18 and avoid tangling. The B-side traction roller 14 provides output power. The combination of the first B-side guide roller 12, the B-side traction roller 14, and the second B-side guide roller 15 realizes the guiding and traction operation of the slitting B-side fabric 18.

[0027] Please see Figure 1 The adjustment components include a slide rail mounting base 19, a slide rail 20, a slider 21, a motor base 23, a servo motor 24, and a lead screw 25. The slide rail mounting base 19 is mounted on the frame 1 of the splitting machine to provide a support base. The slide rail 20 and the motor base 23 are both mounted on the slide rail mounting base 19. The slider 21 is mounted on the slide rail 20 and is connected to the gantry 22. The servo motor 24 is fixedly mounted on the motor base 23. The output end of the servo motor 24 is connected to one end of the lead screw 25 through a coupling. The lead screw 25 is threadedly connected to the slider 21. The servo motor 24 drives the slider 21 to move through the lead screw 25. The movement of the slider 21 drives the gantry 22 to move, achieving precise positioning. The servo motor 24 provides high-precision control, and the lead screw 25 transmission ensures fast response and an error of less than 0.1mm.

[0028] The working principle of this fully automated splitting machine is as follows: A double-layer fabric 16 enters the machine frame through the fabric inlet 2. The first feed guide roller 3 initially guides the fabric, and the spreading roller 4 laterally flattens the fabric to eliminate wrinkles. The feed traction roller 5 and the second feed guide roller 6 work together to pull the fabric forward at a uniform speed, ensuring even tension. This stage prepares for splitting, preventing fabric deviation or deformation. Then, the double-layer fabric 16 moves through the middle of two sets of gantry 22 to the position of the blade 7. The blade precisely splits the double-layer fabric 16 into independent A-side fabric 17 and B-side fabric 18. The splitting process is completed above the machine frame. Utilizing the sharp edge of the blade, fiber damage is reduced, and the splitting accuracy can reach millimeter level. After splitting, the A-side fabric 17 and B-side fabric 18 are respectively guided out of the machine frame by the cooperation of their respective guide rollers and traction rollers. During this process, the A-side fabric 17 and B-side fabric 18... 8 will detect the pile length of the fabric using the A-side fabric density measuring instrument 9 and the B-side fabric density measuring instrument 13 respectively. The A-side fabric density measuring instrument 9 measures the density of the A-side fabric 17, and the B-side fabric density measuring instrument 13 measures the density of the B-side fabric 18. By comparing the density difference between the A and B sides, the pile length difference between the A and B sides can be calculated. The A-side fabric density measuring instrument 9 and the B-side fabric density measuring instrument 13 transmit the measured values ​​to the PLC controller built into the splitting machine. When the pile length of the A-side fabric 17 is greater than that of the B-side fabric 18, the adjustment component of the A-side fabric 17 area will drive the gantry 22 at that position to move towards the B-side fabric 18 area. Similarly, when the pile length of the B-side fabric 18 is greater than that of the A-side fabric 17, the adjustment component of the B-side fabric 18 area will drive the gantry 22 at that position to move towards the A-side fabric 17 area, thereby adjusting the pile length deviation so that the pile lengths of the A and B sides are the same.
