Description

Technical Field

[0001] This invention relates to the field of cutting bed technology, and specifically to a cutting bed and method for multi-layer, large-volume fabrics. Background Technology

[0002] Chinese patent application CN120155965A discloses an annular air-blowing cooling structure for a cutting blade, including a pressure plate, a guide base, a cutting blade, and a blade rail. The guide base is rotatably mounted within the pressure plate, and the blade rail is mounted within the guide base. The cutting blade moves vertically up and down within the blade rail. The guide base includes an upper guide base and a lower guide base, with an annular air inlet chamber connected to an air source between the upper and lower guide bases. An axially arranged air guide hole is provided within the upper guide base, and the air guide hole is connected to the annular air inlet chamber via an annular air inlet gap. The diameter of the air guide hole gradually decreases from bottom to top, and its hole wall forms an inwardly converging air guide surface. The air guide surface guides the gas to flow upward along its profile to the cutting blade. This invention provides an annular air-blowing cooling structure for a cutting blade, which can guide the cooling airflow upward for better cooling of the cutting blade. However, this structure and existing technologies still have the following technical problems: 1. When processing large quantities of multi-layered fabrics continuously, relying solely on air blowing to remove heat from the blade is inefficient. Applying water mist will reduce fabric quality and affect subsequent processing of the fabric. 2. When cutting fabric, it is necessary to press and fix the fabric in front of and behind the cutter. However, due to the nature of the fabric and the cutting process, the thickness of the fabric in different positions is slightly different. If the fabric is pressed and fixed by a single pressure roller, the fabric will be more prone to crumbling due to uneven force, which will affect the quality of the cut fabric.

[0003] Based on this, the present invention designs a cutting bed and method for multi-layer, large-volume fabrics to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cutting bed and method for multi-layer, large-volume fabrics.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A cutting bed for multi-layer, high-volume fabric cutting includes a bed frame, a Y-axis linear module, an X-axis linear module, a Z-axis linear module, a first support frame, and a second support frame. A Y-axis linear module is fixedly installed at the upper end of the bed. A first support frame is fixedly installed at the moving end of the Y-axis linear module. An X-axis linear module is fixedly installed on the first support frame. A second support frame is fixedly installed at the moving end of the X-axis linear module. The Y-axis linear module is used to drive the first support frame to move along the length direction of the bed, and the X-axis linear module is used to drive the second support frame to move along the width direction of the bed. A Z-axis linear module is fixedly installed at the rear end of the second support frame. A reciprocating power device is fixedly installed at the moving end of the Z-axis linear module. The output end of the reciprocating power device is fixedly connected to the upper end of the cutting blade. The Z-axis linear module is used to drive the reciprocating power device and the cutting blade to move vertically up and down. The reciprocating power device is used to drive the cutting blade to vibrate vertically at high frequency to perform fabric cutting operations. A blade limiting mechanism is installed on the second support frame. The blade limiting mechanism is used to make the cutting blade move stably vertically to perform fabric cutting operations. The second support frame is also equipped with a blade water cooling mechanism, which includes a fixing block, a power unit, and an enveloping spray cooling component. The fixing block is installed on the blade limiting mechanism, and the enveloping spray cooling component is installed on the fixing block. The enveloping spray cooling component is used to spray and cool the blade of the cutting knife and to recover the sprayed material around the spray point. The power unit is fixedly installed on the second support frame and is used to provide power to the enveloping spray cooling component.

[0006] Furthermore, the enclosed spray cooling assembly includes a U-shaped groove, a nozzle, a stop block, and a collection groove. The fixing block has a U-shaped groove for the cutting blade to pass through, and the stop blocks are fixedly installed on both sides of the opening end of the U-shaped groove. The nozzle is fixedly installed in the middle of the inner wall of the U-shaped groove, and the nozzle is aligned with the cutting edge of the cutting blade. The inner wall of the U-shaped groove also has two collection grooves, which are located on the upper and lower sides of the nozzle, respectively.

[0007] Furthermore, the jet pump and the recovery pump are fixedly mounted on the second support frame. The outlet of the jet pump is connected to the nozzle through a pipeline, and the inlet of the recovery pump is connected to the collection tank through a pipeline.

[0008] Furthermore, the blade limiting mechanism includes an upper rotating disk, a lower pressure disk, a fabric pressing cylinder, a rotating power device, and a multi-directional limiting component. The upper rotating disk is rotatably mounted on the second support frame via bearings. The fabric pressing cylinder is fixedly mounted on the lower end of the upper rotating disk, and the output end of the fabric pressing cylinder is fixedly connected to the lower pressure disk. The rotating power device is mounted on the second support frame and is driven by the upper rotating disk. The lower pressure disk is fixedly connected to the fixed block.

[0009] Furthermore, the multi-directional limiting assembly includes an upper limiting wheel, a lower limiting wheel, a flange, and a limiting groove. Multiple upper limiting wheels for limiting the upper part of the cutting blade are rotatably mounted on the upper rotating disk via bearings, and multiple upper limiting wheels for limiting the lower part of the cutting blade are rotatably mounted on the lower pressure plate via bearings. Through slots for the cutting blade to pass through are respectively opened on the upper rotating disk and the lower pressure plate.

[0010] Furthermore, there are two sets of upper limit wheels, with each set of upper limit wheels located on opposite sides of the cutter. The four upper limit wheels work together to limit the four sides of the upper part of the cutter. There is one set of lower limit wheels, with each lower limit wheel located on one of the two sides of the cutter blade. A flange is provided in the middle of the lower limit wheel, and a limiting groove that mates with the flange is provided on the side of the cutter.

[0011] Furthermore, a segmented floating re-coating and pressing mechanism is installed on the first support frame. The segmented floating re-coating and pressing mechanism includes a lifting linear module, a film take-up and release assembly, and a pressing roller. Two lifting linear modules are symmetrically fixedly installed on the left and right sides of the first support frame. Support side plates are fixedly installed on the moving ends of the lifting linear modules. A film take-up and release assembly and a pressing roller are installed between the two support side plates. There are two pressing rollers, which are located on the front and rear sides of the cutter, respectively.

[0012] Furthermore, the pressing roller consists of a pressing shaft and a pressing sleeve. The pressing shaft is rotatably connected to the support side plate. The inner side of the pressing sleeve has an installation hole for the pressing shaft to pass through. The pressing sleeve is fitted on the outer side of the pressing shaft and rotates synchronously with the pressing shaft. The mounting hole of the pressing sleeve and the pressing shaft are connected by a clearance fit.

[0013] To better achieve the objectives of this invention, the present invention also provides a cutting bed and method for multi-layer, high-volume fabrics, comprising the following steps: Step 1: The reciprocating power device drives the cutting blade to vibrate and cut the fabric; Step 2: Four upper limit wheels work together to limit the upper part of the cutting blade, and two lower limit wheels work together to limit the lower part of the cutting blade. The lower limit wheels, through flanges and limiting grooves, enable the cutting blade to vibrate stably vertically even when extended. Step 3: During the fabric cutting process, the cutter moves within the U-shaped groove of the fixed block. The jet pump sprays low-temperature liquid or low-temperature mist from the nozzle to the cutting edge of the cutter. The recovery pump then controls the collection tanks on both sides of the nozzle to collect the heat-exchanged liquid, ensuring that the heat exchange medium only exists between the two collection tanks and does not leak onto the fabric being cut.

[0014] Compared to existing technologies, the advantages of this invention are as follows: A reciprocating power device provides power to the cutting blade, causing it to vibrate at high speed under the limiting action of the blade body limiting mechanism. The Y-axis linear module, X-axis linear module, and Z-axis linear module work together to control the position of the cutting blade, enabling it to cut the fabric. During the cutting operation, the power device powers the surrounding spray cooling component, which sprays heat to cool the blade edge and recovers the sprayed material around the spray point, thereby achieving cooling of the cutting blade. The efficient cooling system enables the cutter to continuously process large quantities of multi-layered fabric, preventing the blade from sticking to the fabric due to high temperatures and avoiding the fabric from being wetted by sprays or liquids, which would reduce the quality of the fabric. This facilitates subsequent processing of the fabric. While cutting the fabric, a segmented floating re-coating and pressing mechanism is used to press and fix the fabric on the front and back sides of the cutter to the bed, and to re-coat the cut areas of the fabric to ensure that the fabric does not shift during processing, thus significantly improving the cutting accuracy of the fabric.

[0020] In some embodiments, please refer to the accompanying drawings. Figures 1-10 A cutting bed for multi-layer, large-volume fabrics includes a bed body 10, a Y-axis linear module 11, an X-axis linear module 12, a Z-axis linear module 13, a first support frame 14, and a second support frame 15. A Y-axis linear module 11 is fixedly installed at the upper end of the bed 10. A first support frame 14 is fixedly installed at the moving end of the Y-axis linear module 11. An X-axis linear module 12 is fixedly installed on the first support frame 14. A second support frame 15 is fixedly installed at the moving end of the X-axis linear module 12. The Y-axis linear module 11 is used to drive the first support frame 14 to move along the length direction of the bed 10, and the X-axis linear module 12 is used to drive the second support frame 15 to move along the width direction of the bed 10. A Z-axis linear module 13 is fixedly installed at the rear end of the second support frame 15. A reciprocating power device 16 is fixedly installed at the moving end of the Z-axis linear module 13. The output end of the reciprocating power device 16 is fixedly connected to the upper end of the cutting blade 2. The Z-axis linear module 13 is used to drive the reciprocating power device 16 and the cutting blade 2 to move vertically up and down. The reciprocating power device 16 is used to drive the cutting blade 2 to vibrate vertically at high frequency to perform fabric cutting operations. A blade limiting mechanism 3 is installed on the second support frame 15. The blade limiting mechanism 3 is used to make the cutting blade 2 move stably vertically to perform fabric cutting operations. The second support frame 15 is also equipped with a blade water cooling mechanism 4. The blade water cooling mechanism 4 includes a fixing block 41, a power unit, and an enveloping spray cooling component. The fixing block 41 is installed on the blade limiting mechanism 3. The enveloping spray cooling component is installed on the fixing block 41. The enveloping spray cooling component is used to spray and cool the blade of the cutting knife 2 and to recover the sprayed material around the spray point. The power unit is fixedly installed on the second support frame 15 and is used to provide power to the enveloping spray cooling component. The first support frame 14 is equipped with a segmented floating re-coating and pressing mechanism 5. The segmented floating re-coating and pressing mechanism 5 is used to press and fix the fabric on the front and rear sides of the cutter 2 onto the bed 10, and to re-coat the area of ​​the fabric that has been cut.

[0021] In this embodiment, the Y-axis linear module 11 and the X-axis linear module 12 adopt a gear and rack module, and the Z-axis linear module 13 adopts a lead screw module.

[0022] In this embodiment, the reciprocating power device 16 adopts a crank-slider power structure.

[0023] In this invention, the reciprocating power device 16 provides power to the cutting blade 2, causing the cutting blade 2 to vibrate at high speed under the limiting action of the blade body limiting mechanism 3. The Y-axis linear module 11, X-axis linear module 12, and Z-axis linear module 13 work together to control the position of the cutting blade 2, enabling the cutting blade 2 to cut the fabric. During the cutting operation, the power device provides power to the surrounding spray cooling component, which sprays and cools the blade of the cutting blade 2, and recovers the sprayed material around the spray point, thereby achieving high temperature control of the cutting blade 2. Effective cooling allows the cutter 2 to continuously process large quantities of multi-layered fabric, preventing the blade from sticking to the fabric due to high temperatures and avoiding the fabric from being wetted by sprays or liquids, which would reduce the quality of the fabric. This facilitates subsequent processing of the fabric. While cutting the fabric, the segmented floating re-coating and pressing mechanism 5 is used to press and fix the fabric on the front and back sides of the cutter 2 onto the bed 10, and re-coating the cut areas of the fabric to ensure that the fabric does not shift during processing, thereby significantly improving the cutting accuracy of the fabric.

[0024] The enclosed spray cooling assembly includes a U-shaped groove 42, a nozzle 43, a stop block 44, and a collection groove 45. The fixing block 41 has a U-shaped groove 42 for the cutter 2 to pass through, and the stop blocks 44 are fixedly installed on both sides of the opening end of the U-shaped groove 42. The nozzle 43 is fixedly installed in the middle of the inner wall of the U-shaped groove 42, and the nozzle 43 is aligned with the blade of the cutter 2. The inner wall of the U-shaped groove 42 also has two collection grooves 45, which are located on the upper and lower sides of the nozzle 43, respectively. The spray pump 46 and the recovery pump 47 are fixedly installed on the second support frame 15. The outlet of the spray pump 46 is connected to the nozzle 43 through a pipeline, and the inlet of the recovery pump 47 is connected to the collection groove 45 through a pipeline.

[0025] The blade limiting mechanism 3 includes an upper rotating disk 31, a lower pressing disk 32, a cloth pressing cylinder 33, a rotary power device, and a multi-directional limiting component. The upper rotating disk 31 is rotatably mounted on the second support frame 15 via bearings. The cloth pressing cylinder 33 is fixedly mounted on the lower end of the upper rotating disk 31, and the output end of the cloth pressing cylinder 33 is fixedly connected to the lower pressing disk 32. The rotary power device is mounted on the second support frame 15 and is drivenly connected to the upper rotating disk 31. The lower pressing disk 32 is fixedly connected to the fixing block 41. The cloth pressing cylinder 33 controls the lower pressing disk 32 to move downward to perform the cloth pressing action. In this embodiment, the rotating power device includes a rotary motor 34 and a transmission assembly 35. The rotary motor 34 is fixedly mounted on the second support frame 15. The output end of the rotary motor 34 is connected to the upper rotating disk 31 through the transmission assembly 35. The transmission assembly 35 adopts a reduction gear transmission structure.

[0026] The multi-directional limiting assembly includes an upper limiting wheel 36, a lower limiting wheel 37, a flange 38, and a limiting groove 39. Multiple upper limiting wheels 36 for limiting the upper part of the cutting blade 2 are rotatably mounted on the upper rotating disk 31 via bearings. Multiple upper limiting wheels 36 for limiting the lower part of the cutting blade 2 are rotatably mounted on the lower pressure disk 32 via bearings. Through slots for the cutting blade 2 to pass through are respectively opened on the upper rotating disk 31 and the lower pressure disk 32. In this embodiment, two sets of upper limit wheels 36 are arranged in pairs, with the upper limit wheels 36 in each set located on opposite sides of the cutter 2. The four upper limit wheels 36 cooperate to limit the four surfaces of the upper part of the cutter 2. A set of lower limit wheels 37 are arranged in pairs, and the lower limit wheels 37 are located on two sides of the cutting edge of the cutter 2. A flange 38 is provided in the middle of the lower limit wheel 37, and a limiting groove 39 that cooperates with the flange 38 is provided on the side of the cutter 2. In this invention, when the reciprocating power device 16 drives the cutting blade 2 to vibrate and cut fabric, the rotary motor 34 drives the upper rotating disk 31 to rotate through the transmission assembly 35, thereby controlling the angle of the cutting blade 2. Four upper limit wheels 36 cooperate to limit the upper part of the cutting blade 2, and two lower limit wheels 37 cooperate to limit the lower part of the cutting blade 2. The lower limit wheels 37, through the flange 38 and the limiting groove 39, ensure that the cutting blade 2 can still vibrate stably vertically in its extended state, while also preventing contact with the blade edge of the cutting blade 2 and thus avoiding damage. The wear of the blade of the cutter 2 is reduced, and the accuracy of the cutter 2 in cutting the fabric is significantly improved. During the cutting process, the cutter 2 moves in the U-shaped groove 42 of the fixed block 41. The low-temperature liquid or low-temperature mist is sprayed from the nozzle 43 to the blade of the cutter 2 by the jet pump 46 for heat exchange. Then, the collection tanks 45 on the upper and lower sides of the nozzle 43 are controlled by the recovery pump 47 to collect the liquid after heat exchange. This ensures that the heat exchange medium only exists between the upper and lower collection tanks 45 and does not leak onto the cut fabric, thus reducing the quality of the fabric.

[0027] The segmented floating re-coating and pressing mechanism 5 includes a lifting linear module 51, a film take-up and release assembly, and a pressing roller 56. Two lifting linear modules 51 are symmetrically fixedly installed on the left and right sides of the first support frame 14. The moving ends of the lifting linear modules 51 are all fixedly installed with support side plates 52. The film take-up and release assembly and the pressing roller 56 are installed between the two support side plates 52. There are two pressing rollers 56, which are located on the front and rear sides of the cutter 2, respectively.

[0028] The film feeding and receiving assembly includes a film feeding roller 53, a film guiding roller 54, and a third motor 55. The film feeding roller 53 is rotatably connected to the support side plate 52. Two film guiding rollers 54 are provided and rotatably connected to the support side plate 52, and a gap is provided between the two film guiding rollers 54 for the film to pass through. The third motor 55 is fixedly connected to the support side plate 52, and the output end of the third motor 55 is fixedly connected to any one of the film guiding rollers 54. A tensioning device (not shown in the figure) for controlling the tension of the film is also installed between the film feeding roller 53 and the film guiding roller 54. The pressing roller 56 is composed of a pressing shaft 561 and a pressing sleeve 562. The pressing shaft 561 is rotatably connected to the support side plate 52. The inner side of the pressing sleeve 562 is provided with an installation hole for the pressing shaft 561 to pass through. The pressing sleeve 562 is sleeved on the outer side of the pressing shaft 561 and rotates synchronously with the pressing sleeve 562. Please see Figure 5 In this embodiment, the mounting hole of the pressing sleeve 562 and the pressing shaft 561 are connected by a clearance fit structure, so that after the pressing sleeve 562 is sleeved on the outside of the pressing shaft 561, the pressing sleeve 562 can rotate synchronously with the pressing shaft 561, and the pressing sleeve 562 can also have a certain relative movement space relative to the pressing shaft 561. Thus, during the pressing operation, the pressing sleeve 562 can adapt to the uneven height of the fabric.

[0029] In this embodiment, multiple pressure sleeves 562 are evenly spaced along the length of the pressure shaft 561, and each pressure sleeve 562 can move independently, thereby effectively increasing the flexibility of the pressure roller 56.

[0030] In this invention, when the cutter 2 is cutting the fabric, the lifting linear module 51 drives the support side plate 52 to move vertically downward, so that the pressing sleeve 562 of the pressing roller 56 presses down on the fabric, so that the fabric is pressed and fixed on the bed 10. During the back-and-forth movement of the first support frame 14, the third motor 55 drives the guide roller 54 to rotate. The two guide rollers 54 cooperate to pull the film roll on the film release roller 53 to realize automatic film release and re-coating of the cut fabric. The cooperation of multiple independent pressing sleeves 562 can evenly press the fabric and improve the accuracy of cutting.

[0031] In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, a method of using a cutting bed for multi-layer, large-volume fabrics includes the following steps: Step 1: The reciprocating power device 16 drives the cutting blade 2 to vibrate and cut the fabric; Step 2: The four upper limit wheels 36 cooperate to limit the upper part of the cutting blade 2, and the two lower limit wheels 37 cooperate to limit the lower part of the cutting blade 2. The lower limit wheels 37, through the flange 38 and the limiting groove 39, enable the cutting blade 2 to vibrate stably in the vertical direction even when it is extended. Step 3: During the fabric cutting process, the cutter 2 will move within the U-shaped groove 42 of the fixed block 41. The low-temperature liquid or low-temperature mist is sprayed from the nozzle 43 to the cutting edge of the cutter 2 by the jet pump 46. Then, the heat exchange liquid is collected by the collection tanks 45 on both sides of the nozzle 43 by the recovery pump 47, so that the heat exchange medium will only exist between the two collection tanks 45 and will not leak onto the cut fabric.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
