Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a cutting device for textiles with a guiding structure. Background Technology

[0002] In the textile industry, fabric processing often requires cutting rolls of fabric into finished or semi-finished products of varying widths to meet subsequent production needs, facilitating sewing, dyeing, and other processing steps. In these scenarios, specialized fabric cutting devices are typically used. These devices feed the fabric through a feeding component, which in turn works with a cutting component to complete the cutting operation. They are adaptable to the processing needs of various common textile fabrics, including cotton, synthetic fibers, and knitted fabrics, and are crucial equipment in the fabric pretreatment stage.

[0003] In existing fabric cutting devices, the cutting blades are mostly fixed, and the blades are prone to excessive wear in certain areas, requiring frequent machine stops to adjust the blades. This increases the amount of manual labor and interrupts continuous production. In addition, the fine fibers generated during cutting can easily adhere to the surface of the cut fabric or drift into the operating environment, affecting product quality and causing pollution to the site. To address the above problems, this invention proposes a textile fabric cutting device with a guiding structure. Summary of the Invention

[0004] This invention provides a cutting device for textile fabrics with a guiding structure, which overcomes the shortcomings of the prior art.

[0005] This invention provides the following technical solution:

[0006] A cutting device for textile fabrics with a guiding structure includes a frame, with an upper winding roller and two take-up rollers respectively installed at both ends of the frame;

[0007] The top of the frame is fixedly connected to two first guide rails, each of which is slidably connected to a slider. The opposite sides of the sliders are fixed with mounting plates by bolts. A cutter roller is fixedly connected between the mounting plates. A mounting frame is slidably fitted around the circumference of the cutter roller. An inclined cutter is fixed to one side of the mounting frame by bolts. The mounting frame and the cutter roller are fixed by set screws.

[0008] A guiding mechanism, which is located at the top of the frame, is used to guide the fabric;

[0009] A pair of drive mechanisms are respectively set on both sides of the frame to drive the cutter to move up and down. The drive mechanisms have the same structure and are arranged symmetrically.

[0010] Furthermore, the guiding mechanism includes a flattening roller and a fixed frame. The flattening roller is rotatably connected to the top of the frame, and the fixed frame is fixed to one side of the frame. A motor is fixedly connected to one side of the fixed frame, and one end of the motor output shaft is fixed to the flattening roller.

[0011] Furthermore, the driving mechanism includes a vertical plate fixed to the top of the frame, a second guide rail fixedly connected to one side of the vertical plate, a slide plate slidably connected inside the second guide rail, and a first support rod and a second support rod rotatably connected to both ends of the slide plate, with the first support rod rotatably connected to the slide block.

[0012] Furthermore, the drive mechanism also includes a mounting shaft, which is rotatably connected to one side of the fixed frame. Gears are fixedly connected to both the circumference of the mounting shaft and the circumference of the flattening roller, and the two gears mesh. A turntable is fixedly connected to one end of the mounting shaft, and an eccentrically set drive shaft is fixedly connected to one side of the turntable. The drive shaft is rotatably connected to the second support rod.

[0013] Furthermore, an exhaust box is fixedly connected to the top of the frame, with the exhaust box opening upward and located between the cutter and the take-up roller. A base plate is fixedly connected to the bottom of the frame, and a filter box and a fan are fixedly connected to the surface of the base plate. A filter screen is fixed inside the filter box, and the exhaust end of the fan is fixedly connected to the filter box. An exhaust pipe is fixedly connected between the bottom of the filter box and the exhaust box.

[0014] Furthermore, a support roller is rotatably connected between the two sides of the exhaust box. The support roller is made of rubber and has an arc shape in the middle, with the arc shape facing upwards.

[0015] Furthermore, both ends of the support roller are fixedly connected to drive rods, and the drive rods are rotatably connected to the sliders by third support rods.

[0016] Furthermore, multiple guide rollers are rotatably connected between the two sides of the frame.

[0017] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0018] In this invention, the flattening roller, motor, and multiple guide rollers work together. The motor drives the textured flattening roller to rotate, generating lateral tension on the fabric to flatten wrinkles. The guide rollers support the fabric along the conveying path to prevent deviation, ensuring the fabric always enters the cutting stage in a flat state. This effectively prevents cutting position deviations or incomplete cutting caused by fabric wrinkles, thus improving the accuracy of fabric cutting.

[0019] In this invention, the motor, gears, mounting shaft, turntable, support rod, slider and cutter are used in combination. The motor drives the mounting shaft and turntable to rotate through the gears. The eccentric drive shaft drives the slider to move up and down through the support rod, which in turn drives the cutter to move up and down. This allows the cutter blade to fully contact the fabric, avoiding excessive wear of the blade in certain areas. It eliminates the need for frequent machine stops to adjust the cutter, reduces manual labor, ensures continuous cutting operations, and improves production efficiency.

[0020] In this invention, the fan, exhaust box, filter box, filter screen and support roller work together to generate suction in the exhaust box. The support roller swings with the slider to separate the cut fabric, making it easier for fine fibers to be sucked into the exhaust box. Then, the fibers enter the filter box through the exhaust pipe and are intercepted by the filter screen. This not only prevents fibers from adhering to the fabric and affecting product quality, but also prevents fibers from scattering and polluting the environment, thus maintaining product quality and a clean operating environment.

[0032] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0033] Example 1

[0034] Reference Figures 1-7 A textile fabric cutting device with a guiding structure includes a frame 1. At each end of the frame 1 are an upper winding roller 2 and two take-up rollers 3. The upper winding roller 2 is used to hold the roll of fabric to be cut, serving as the supply end of the fabric. The two take-up rollers 3 are arranged vertically to collect and roll up the cut fabric. Multiple guide rollers 4 are rotatably connected between the two sides of the frame 1. These guide rollers 4 are evenly distributed along the fabric conveying path, providing support and guidance to the fabric, preventing it from shifting or sagging during conveying, and ensuring that the fabric always moves stably along the preset path.

[0035] At the top of the frame 1, two parallel first guide rails 10 are fixedly connected. Each first guide rail 10 has a slider 15 slidably connected inside, and the slider 15 can move up and down along the first guide rail 10. On the opposite side of the slider 15, a mounting plate 11 is fixedly fixed by bolts. The bolt connection facilitates subsequent disassembly and maintenance. A cutter roller 12 is fixedly connected between the two mounting plates 11. The cutter roller 12 is in a horizontal state, and its axis is perpendicular to the fabric conveying direction. On the circumferential surface of the cutter roller 12, multiple mounting brackets 13 are slidably sleeved. One side of the cutter roller 12 is provided with a plane that matches the mounting bracket 13, thereby preventing rotation after the mounting bracket 13 is inserted. The number of mounting frames 13 can be adjusted according to the number of fabric strips to be cut. Each mounting frame 13 has an inclined cutter 14 fixed to one side by bolts. The blade of the cutter 14 faces the fabric conveying direction, and the inclination angle can be finely adjusted according to the fabric thickness to ensure that the blade can smoothly cut into the fabric during cutting. The mounting frame 13 is fixed to the cutter roller 12 by a set screw. Loosening the set screw will push the mounting frame 13 to slide on the cutter roller 12. Adjusting the distance between two adjacent mounting frames 13 will adjust the distance between the cutters 14 to adapt to the cutting needs of fabrics of different widths. After adjustment, tightening the set screw will fix the position of the mounting frame 13.

[0036] To ensure the fabric remains flat before cutting, the device is equipped with a guiding mechanism, which includes a flattening roller 19 and a fixed frame 17. The flattening roller 19 is rotatably connected to the top of the frame 1 via a bearing seat, located on the fabric conveying path between the upper winding roller 2 and the cutter 14. The fixed frame 17 is fixed to one side of the frame 1, and a motor 18 is bolted to one side of the fixed frame 17. One end of the output shaft of the motor 18 passes through the side wall of the fixed frame 17 and is fixedly connected to one end of the flattening roller 19. In use, the fabric on the upper winding roller 2 is first guided to the flattening roller 19 by the guide roller 4. The motor 18 is started, and the output shaft of the motor 18 drives the flattening roller 19 to rotate. When the texture on the surface of the flattening roller 19 comes into contact with the fabric, it generates lateral tension on the fabric surface, thereby unfolding the wrinkles on the fabric surface and keeping the fabric flat for subsequent cutting. This avoids the cutting position shift or incomplete cutting due to fabric wrinkles.

[0037] Example 2

[0038] Reference Figures 1-7 Based on Example 1, an improved cutting device for textile fabrics with a guide structure is proposed.

[0039] The device also includes a pair of drive mechanisms, respectively located on both sides of the frame 1. The drive mechanisms on both sides have identical structures and are symmetrically distributed, used to drive the cutter 14 to move up and down. Each drive mechanism includes a vertical plate 16, which is vertically fixed to the top of the frame 1. A second guide rail 20 is bolted to one side of the vertical plate 16. The second guide rail 20 is horizontal, and a sliding plate 21 is slidably connected inside it. The sliding plate 21 can move along the length of the second guide rail 20. At both ends of the sliding plate 21, a first support rod 22 and a second support rod 26 are rotatably connected via pivots. The end of the first support rod 22 furthest from the sliding plate 21 is rotatably connected to the side of the slider 15 via a pivot.

[0040] The drive mechanism also includes a mounting shaft 24, which is rotatably connected to one side of the fixed frame 17 via bearings, and the axis of the mounting shaft 24 is parallel to the axis of the flattening roller 19. Gears 23 are fixedly connected by keys on both the circumferential surface of the mounting shaft 24 and the circumferential surface of the flattening roller 19. The two gears 23 mesh with each other to ensure that the flattening roller 19 can synchronously drive the mounting shaft 24 to rotate when it rotates, thereby reducing the rotational speed of the mounting shaft 24. A turntable 31 is fixed to the end of the mounting shaft 24 away from the gears 23 by bolts. An eccentrically set drive shaft 25 is fixedly connected to one side surface of the turntable 31. The axis of the drive shaft 25 does not coincide with that of the turntable 31. The end of the drive shaft 25 away from the turntable 31 is rotatably connected to the end of the second support rod 26 away from the slide plate 21 via a rotating shaft. When the flattening roller 19 rotates under the drive of the motor 18, it drives the mounting shaft 24 to rotate through two meshing gears 23. The mounting shaft 24 drives the turntable 31 to rotate synchronously. The drive shaft 25 on the turntable 31 moves in a circular motion with the turntable 31. Due to the eccentric setting of the drive shaft 25, it will continuously pull or push the second support rod 26 during rotation, thereby driving the slide plate 21 to move back and forth within the second guide rail 20. When the slide plate 21 moves, it will push and pull the slider 15 back and forth through the first support rod 22, causing the slider 15 to move up and down within the first guide rail 10. The slider 15 drives the mounting plate 11 and the cutter roller 12 to move up and down. The cutter roller 12 drives the cutter 14 to move up and down. In this way, when the cutter 14 cuts the fabric, the blade surface can make more comprehensive contact with the fabric, avoiding excessive wear of the blade in some areas, keeping the blade wear uniform, eliminating the need for frequent machine stops to adjust the blade, reducing manual labor, and improving overall production efficiency.

[0041] To handle the fine fibers generated during the cutting process, an exhaust box 9 is fixedly connected to the top of the frame 1. The opening of the exhaust box 9 faces upward and is positioned between the cutter 14 and the take-up roller 3, ensuring that the fabric can pass over the exhaust box 9 immediately after cutting. A base plate 5 is bolted to the bottom of the frame 1. The base plate 5 is a horizontally arranged metal plate used to install the filter box 6 and the fan 7. Both the filter box 6 and the fan 7 are fixed to the surface of the base plate 5. A filter screen 8 is fixed inside the filter box 6. The filter screen 8 is made of non-woven fabric and can effectively filter fine fibers. The exhaust end of the fan 7 is fixedly connected to one side of the filter box 6 through a pipe. The top of the filter box 6 and the bottom of the exhaust box 9 are fixedly connected through an exhaust pipe 30. The exhaust pipe 30 is made of rigid plastic to ensure stable airflow. When cutting the fabric, the blower 7 can be started. When the blower 7 is working, it will create a negative pressure inside the filter box 6. The negative pressure is transmitted to the exhaust box 9 through the exhaust pipe 30, which will generate suction at the opening of the exhaust box 9. The fine fibers produced after the fabric is cut by the cutter 14 will be sucked into the exhaust box 9 and then enter the filter box 6 through the exhaust pipe 30. They will be intercepted and filtered by the filter screen 8 inside the filter box 6. The filtered air will be discharged through the exhaust end of the blower 7. This not only prevents fine fibers from adhering to the cut fabric and ensuring product quality, but also prevents fibers from scattering into the air and keeping the on-site operating environment clean.

[0042] Between the two sides of the exhaust box 9, a support roller 27 is rotatably connected via bearings. The support roller 27 is made of rubber and has a certain degree of elasticity, which can prevent scratches on the fabric surface. The middle part of the support roller 27 is arc-shaped and the arc part is set upward to form an upward convex support surface. Both ends of the support roller 27 are fixed with drive rods 28 by welding. The drive rods 28 are in a horizontal state and extend away from the axis of the support roller 27. The end of each drive rod 28 away from the support roller 27 is rotatably connected to one end of a third support rod 29 via a rotating shaft. The other end of the third support rod 29 is rotatably connected to the bottom of the slider 15 via a rotating shaft. When the slider 15 moves up and down within the first guide rail 10, it pushes and pulls the drive rod 28 back and forth via the third support rod 29. The drive rod 28 drives the support roller 27 to swing back and forth between the two sides of the exhaust box 9. The arc-shaped structure in the middle of the support roller 27 can gently separate the cut fabric during the swinging process, so that a certain gap is maintained between the multiple cut fabric strips, making it easier for the fine fibers on the surface of the fabric to be exposed within the suction range of the exhaust box 9, thereby improving the fiber extraction effect and ensuring more thorough fiber collection.

[0043] However, as is well known to those skilled in the art, the working principles and wiring methods of the fan 7 and the motor 18 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0044] The working principle and usage process of this technical solution are as follows: When in use, the upper roller 2 is used to feed the material, and the winding roller 3 is used to roll up the cut fabric. The fabric is cut to the set width when it passes through the cutter 14.

[0045] During cutting, the motor 18 is started, which drives the flattening roller 19 to rotate. The texture on the flattening roller 19 guides the surface to make it flat. At the same time, the fan 7 can be started so that the fine fibers in the fabric after cutting can be drawn into the filter box 6 through the exhaust box 9 and then filtered by the filter screen 8 to maintain product quality and the on-site environment.

[0046] When the flattening roller 19 rotates, it also drives the mounting shaft 24 to rotate via the gear 23. The mounting shaft 24 drives the turntable 31 to rotate. The turntable 31 drives the slide plate 21 to move back and forth via the eccentric mounting drive shaft 25 and the second support rod 26. The slide plate 21 moves up and down by pushing and pulling the slider 15 back and forth via the first support rod 22, which in turn drives the cutter roller 12 and the cutter 14 to move. This makes the cutting edge of the cutter 14 more fully utilized and wear uniformly, avoids the need for cutter adjustment, improves production efficiency, and reduces manual labor.

[0047] During the up-and-down movement of the slider 15, the third support rod 29 reciprocates by pushing and pulling the drive rod 28, which in turn causes the support roller 27 to swing. The arc-shaped setting in the middle of the support roller 27 can separate the cut fabric, making it easier to extract the fibers and improving the extraction effect.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
