Description

Technical Field

[0001] This invention relates to the field of cotton knitted blanket production and processing, specifically to an intelligent ironing and shaping device for cotton knitted blankets. Background Technology

[0002] In the production of knitted blankets, ironing and shaping are crucial processes for improving product appearance, eliminating wrinkles, and stabilizing dimensions. Existing shaping-ironing machines generally use fixed-width box-type steam chambers or roller-type ironing belts, with their effective working width set to a single maximum value at the factory, commonly in sizes of 2 meters, 3 meters, and 4 meters. However, with the increase in personalized orders, the same production line needs to switch between carpet blanks of 1.6 meters, 2.2 meters, 3.3 meters, 4.2 meters, and even narrower or wider widths within a short period. Traditional equipment exhibits the following shortcomings when dealing with carpets of "non-standard width": When the width of the steam chamber is greater than the width of the carpet, the steam jets on both sides that are not covered by the carpet continuously emit high-temperature steam, causing 30% to 50% of the steam to escape directly into the workshop. This not only wastes energy and increases the boiler load, but also causes fogging and condensation on site, worsening the working conditions and making the carpet edges too wet, resulting in color differences.

[0003] When the width of the steam chamber is smaller than the width of the carpet, the sides of the carpet cannot be ironed, requiring the machine to be stopped and the chamber or the entire ironing strip of the corresponding width replaced. The replacement process requires disassembling the insulation cover, lifting the chamber, and reconnecting the piping and transmission, which takes a long time and severely disrupts the continuous production cycle; at the same time, the large inventory of spare chambers / ironing strips ties up capital and space.

[0004] To accommodate different widths, some companies have adopted a "large cover small" approach for a long time, always using the widest cavity, resulting in increased annual steam consumption and exceeding carbon emission standards. Other companies have arranged multiple narrow cavities in segments and staggered positions, but there are temperature dead zones in the seam area, obvious ironing marks, and a downgrade in the quality of the finished product.

[0005] In summary, existing fixed-width ironing devices cannot achieve dynamic matching of steam energy and mechanical width in scenarios with varying carpet widths. There is an urgent need for a technical solution that can adjust the effective ironing width in real time on the same unit according to changes in carpet width, in order to solve the pain points of resource waste, frequent changeovers, and uneven ironing quality.

[0006] Therefore, an intelligent ironing and shaping device for cotton knitted blankets is proposed to address the above problems. Summary of the Invention

[0009] Preferably, each of the movable shells has a double-layer structure on its inner and outer sidewalls, and the end of the fixed shell is slidably and sealed within the double-layer structure of the movable shell.

[0010] Preferably, the ironing module has a roller pressing module on one side. The roller pressing module includes multiple rollers, and the ends of the rollers are provided with support rods. The ends of the support rods are rotatably connected to support plates, and the support plates can support the rollers on the surface of the platform.

[0011] Preferably, a sleeve is provided between the end of the support rod and the roller body. One end of the sleeve is fitted onto the outer surface of the roller body, and the other end of the sleeve is fitted onto the support rod. The other end of the sleeve is connected to the end face of the roller body through a compression spring, which is fitted onto the support rod. A nut is threaded onto the support rod.

[0012] Preferably, a channel is provided at the axial position of each of the support rods and rollers, multiple through holes are provided on the surface of the rollers, and an auxiliary pipe is rotatably connected to the end of the support rod.

[0013] Preferably, the ironing module is provided with a preheating module on the other side, and the preheating module includes a strip shell, which is arranged along the width direction of the platform. A negative pressure pipe is connected to the top of the strip shell, and strip holes are symmetrically opened on both sides of the bottom of the strip shell. Hollow plates are provided on both sides of the strip shell, and multiple steam holes are opened on the lower surface of each hollow plate.

[0014] Preferably, two rotating rollers are symmetrically arranged inside the strip-shaped shell. The two rotating rollers are located below the opening of the negative pressure pipe. Both rotating rollers are provided with roller brushes on their surfaces. The bottom surface of the strip-shaped shell below the two rotating rollers is provided with strip-shaped protrusions.

[0015] Preferably, the strip shell is further provided with a slapping assembly. The slapping assembly has a hollow plate near the other side of the strip shell. The slapping assembly includes multiple rotating rods arranged along the length of the strip shell. Multiple fixing blocks are evenly arranged on each rotating rod. An elastic rod is fixed to the outer surface of each fixing block. A slapping ball is fixed to the end of the elastic rod.

[0016] Preferably, a groove is formed on the other side of the upper surface of the platform, and multiple steam nozzles are arranged in the groove.

[0019] 2. In this invention, a movable sleeve is provided at the end of the roller body. By rotating the nut, two sleeves on the same roller body move towards each other, moving away from or towards each other synchronously. At this time, the sleeves coincide with the end of the roller body, which can increase the diameter of the end of the roller body, so that the squeezing force of the roller body acts on the sleeves, and the sleeves squeeze the edge of the width of the cotton knitted blanket, thereby achieving effective squeezing and smoothing of the fibers in the width direction of the entire cotton knitted blanket.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Reference Figure 1 - Figure 12A smart ironing and shaping device for cotton knitted blankets includes a platform 1, an ironing module on the platform 1, and an ironing module including a strip-shaped heat-insulating shell 2. The heat-insulating shell 2 is set along the width direction of the platform 1, and the bottom of the heat-insulating shell 2 is hollowed out. The heat-insulating shell 2 is symmetrically provided with movable shells 3. Rectangular openings 4 are opened at the opposite edges of the bottom of the two movable shells 3. A fixed shell 5 is provided between the two movable shells 3, and the two ends of the fixed shell 5 extend into the movable shell 3. The two movable shells 3 have their relatively far end faces connected by a common threaded screw 6, the end of which extends through to the outside of the insulation shell 2; the upper end face of the insulation shell 2 has a rectangular hole 7 symmetrically opened, and an air supply pipe 8 is slidably connected inside the rectangular hole 7. The air supply pipe 8 is connected to the inside of the movable shell 3 and to an external air pump. The air pump injects high-temperature steam into the insulation shell 2 and discharges it from the hollowed-out surface at the bottom of the insulation shell 2, spraying it onto the surface of the cotton knitted blanket; In this embodiment of the invention, the end of the heat insulation shell 2 is also provided with a servo motor that drives the lead screw 6 to rotate. The output end of the servo motor can be connected to the lead screw 6 by a gear set drive. At the same time, the servo motor is controlled by a PLC, and a vision sensor is set on the other side of the heat insulation shell 2. The vision sensor captures and acquires the image of the distance between the two sides of the knitted blanket, uploads the image to the image processing system, and determines the width of the knitted blanket that needs to be ironed. Then, it controls the servo motor to rotate, drives the lead screw 6 to move the two moving shells 3 towards each other, which has a certain degree of intelligence. The top of the fixed shell 5 is fixed to the top position inside the insulation shell 2 via the air supply pipe 8. The two ends of the fixed shell 5 are aligned with the movable shell 3. When the lead screw 6 rotates, since the lead screw 6 is threadedly connected to the movable shell 3, the two movable shells 3 move synchronously towards each other, controlling the size of the steam outlet formed by the two rectangular openings 4. This allows for flexible adaptation to ironing cotton knitted blankets of different widths. At the same time, the distance between the two rectangular openings 4 can be infinitely adjusted, making it suitable for ironing various non-standard width cotton knitted blankets. Furthermore, it eliminates the need for operations such as disassembling the insulation cover during the process, allowing for quick start to ironing operations. It also adapts to the width of the cotton knitted blanket, reducing steam consumption, saving heat resources, and meeting carbon emission standards.

[0024] Reference Figure 1 - Figure 12 Each of the movable shells 3 has a double-layer structure on its inner and outer sidewalls, and the end of the fixed shell 5 is sealed and slidably connected inside the double-layer structure of the movable shell 3. Considering the fluidity and permeability of steam, and the ability of high-temperature steam to contact the surface of cotton knitted blankets in a timely manner, the sidewalls of the movable shell 3 are designed with a double-layered structure, such as... Figure 11As shown, the end of the fixed shell 5 can be sealed and slidably connected within the double-layer structure of the inner and outer side wall to reduce the amount of steam overflow. At the same time, the sealed and slidable connection between the movable shell 3 and the fixed shell 5 can also improve the stability of the movable shell 3 during movement. That is, when the drive screw 6 rotates, the movable shell 3 can smoothly make opposite movement movements, reducing the possibility of jamming.

[0025] Reference Figure 1 - Figure 4 ,as well as Figure 17 - Figure 18 The ironing module has a roller pressing module on one side. The roller pressing module includes multiple rollers 9. The ends of the rollers 9 are provided with support rods 10. The ends of the support rods 10 are rotatably connected to support plates 11. The support plates 11 can support the rollers 9 on the upper surface of the platform 1. Adjustable bolts 12 are provided at the bottom of both ends of the heat-insulating shell 2. Rotating the adjustable bolts 12 can control the distance between the bottom of the heat-insulating shell 2 and the upper surface of the platform 1, thus adapting to ironing cotton knitted blankets of different thicknesses. By controlling the distance, the heat-insulating shell 2 can exert pressure on the surface of the cotton knitted blanket. However, when the pressure is too high, it is difficult for steam to escape, and the steam adhesion range is limited, failing to cover all the fibers on the surface of the cotton knitted blanket. Therefore, a separate roller pressing stage is required. The roller pressing stage is used to alleviate the pressure on the cotton knitted blanket and flatten it. Specifically, adjustable bolts 12 are also provided on the support plate 11. These adjustable bolts 12 can control the distance between the roller 9 and the upper surface of the platform 1, thus controlling the pressure on the cotton knitted blanket. After the cotton knitted blanket comes into contact with steam, the surface of the cotton knitted blanket still has residual heat. Then, under the pressing action of multiple rollers 9, the cotton knitted blanket is flattened, improving the quality of the cotton knitted blanket.

[0026] Reference Figure 1 - Figure 4 ,as well as Figure 17 - Figure 18 A sleeve 13 is provided between the end of the support rod 10 and the roller body 9. One end of the sleeve 13 is sleeved on the outer surface of the roller body 9, and the other end of the sleeve 13 is sleeved on the support rod 10. The other end of the sleeve 13 is connected to the end face of the roller body 9 through a compression spring 14. The compression spring 14 is sleeved on the support rod 10, and a nut 15 is threaded on the support rod 10. Considering that the edges of cotton knitted blankets are thinned, meaning the fiber height at the edges is less than the fiber height in the middle, the ends of rollers 9 cannot reach the edges when the blankets are pressed. Therefore, a sleeve 13 is provided. The sleeve 13 can move along the axis of roller 9. Specifically, rotating the nut 15 presses the sleeve 13, which in turn presses the internal spring 14. Two sleeves 13 on the same roller 9 move towards each other, moving away or closer simultaneously. At this point, the sleeve 13 overlaps with the end of roller 9, increasing the diameter of the roller 9 end. This allows the pressing force of roller 9 to act on the sleeve 13, which then presses against the edges of the cotton knitted blanket, effectively smoothing and pressing the fibers throughout the width of the blanket.

[0027] Reference Figure 1 - Figure 4 ,as well as Figure 17 - Figure 18 Each of the support rods 10 and rollers 9 has a channel 16 at its axial position, and multiple through holes 17 are formed on the surface of the rollers 9. The end of the support rod 10 is rotatably connected to an auxiliary pipe. Considering the varying thicknesses of cotton knitted blankets, some thicker blankets require longer steam ironing times. In this embodiment of the invention, the ironing time is extended by supplementing steam twice. Specifically, the auxiliary pipe and the air supply pipe 8 are connected to an external air pump. High-temperature steam is injected into the channel 16 and discharged from multiple through holes 17 on the surface of the roller 9. At the same time, multiple through holes 17 are also opened on the surface of the sleeve 13. The sleeve 13 is fitted onto the end of the roller 9, and the steam is discharged along the through holes 17, which can also take care of ironing the wide edges of the cotton knitted blanket. The roller 9 squeezes and smooths the cotton knitted blanket while discharging steam, extending the steam ironing time of the cotton knitted blanket, so that the steam can fully penetrate to the root of the cotton knitted blanket fiber connection and improve the squeezing and smoothing effect.

[0028] Reference Figure 1 - Figure 4 ,as well as Figure 13 - Figure 16 The ironing module is provided with a preheating module on the other side, and the preheating module includes a strip shell 18. The strip shell 18 is arranged along the width direction of the platform 1. The top of the strip shell 18 is connected to a negative pressure pipe 19, which is connected to an external negative pressure pump. The bottom of the strip shell 18 has symmetrical strip holes 20 on both sides, and both sides of the strip shell 18 are provided with hollow plates 21. Each hollow plate 21 has multiple steam holes on its lower surface. The preheating module first performs preliminary steam heating on the cotton knitted blanket for pretreatment. Specifically, the hollow plate 21 is connected to an external air pump through the air supply pipe 8, and steam can be discharged from multiple steam holes. The cotton knitted blanket is heated according to 4 and... Figure 13 The state shown extends through the lower surface of the hollow board 21 and the strip shell 18. Steam preheats the cotton knitted blanket, making the moisture content of each part of the cotton knitted blanket uniform. Because the moisture content of the surface layer and the core layer of the thick carpet is different, it can be preheated to about 100°C to allow the moisture to migrate outwards and reduce the moisture content difference between each part. This will prevent bubbling or white spots from forming due to the instantaneous expansion of water vapor in the subsequent high-temperature stage. At the same time, it relieves the internal stress of each part of the cotton knitted blanket. Because there is tension and bending stress inside the carpet after weaving and gluing, the fibers shrink freely by 1-2% during the preheating stage. After the stress is released, it is pressed and shaped to avoid the reappearance of "ruffles" or "bowed weft" after cooling. Furthermore, it can pre-cure the adhesive layer of each part of the cotton knitted blanket. Preheating allows the adhesive to initially form a film, so that it will not flow during the formal high-temperature ironing and will not be squeezed onto the carpet surface by the rollers to form adhesive spots. During the preheating process of the cotton knitted blanket, the fibers on its surface become fluffy, and the fibers that are detached from the glue or broken are drawn off by the suction of the negative pressure tube 19, which serves to pre-clean the surface of the cotton knitted blanket.

[0029] Reference Figure 1 - Figure 4 ,as well as Figure 13 - Figure 16 The strip shell 18 is symmetrically provided with two rotating rollers 22. The two rotating rollers 22 are located below the opening of the negative pressure pipe 19. The surface of the two rotating rollers 22 is provided with a roller brush. The bottom surface of the strip shell 18 below the two rotating rollers 22 is provided with a strip-shaped protrusion 23. The two rotating rollers 22 are equipped with independent motor drives, such as Figure 13 As shown, the left roller 22 rotates counterclockwise and the right roller 22 rotates clockwise. Both rollers are equipped with brushes on their surfaces. When the rollers 22 rotate, the brushes can clean out the fibers deeper into the cotton knitted blanket and remove them under the adsorption of the negative pressure tube 19, further cleaning the cotton knitted blanket. The protrusions lift the cotton knitted blanket and bring it closer to the opening of the negative pressure tube 19, improving the adsorption effect.

[0030] Reference Figure 1 - Figure 4 ,as well as Figure 13 - Figure 16The strip shell 18 is also provided with a slapping assembly. The slapping assembly is provided with a hollow plate 21 near the other side of the strip shell 18. The slapping assembly includes a plurality of rotating rods 24 arranged along the length of the strip shell 18. A plurality of fixing blocks are evenly arranged on each rotating rod 24. An elastic rod is fixed to the outer surface of each fixing block. A slapping ball 25 is fixed to the end of the elastic rod. Hollow plates 21 are provided on both sides of the strip-shaped shell 18, such as Figure 13 As shown, the hollow plate 21 on the right preheats the cotton knitted blanket to give it a certain degree of fluffiness. Then, under the high-frequency beating of the beating component, the cotton knitted blanket becomes even fluffier. Specifically, the rotating rod 24 is set up vertically, and the end of the rotating rod 24 is connected to an external motor. The motor drives the rotating rod 24 to rotate, and the beating ball 25 hits the upper surface of the cotton knitted blanket at a high frequency, making it fluffy. When the hollow plate 21 on the left preheats the cotton knitted blanket again, the steam can fully penetrate the deep layers of the cotton knitted blanket, improving the preheating effect.

[0031] Reference Figure 1 - Figure 4 ,as well as Figure 13 - Figure 16 A groove 26 is provided on the other side of the upper surface of the platform 1. Multiple steam nozzles 27 are provided in the groove 26. The steam nozzles 27 are connected to an external air pump. A hollow plate 28 is provided at the opening of the groove 26. The upper surface of the plate 28 is flush with the upper surface of the platform 1. The groove 26 is provided, and multiple steam nozzles 27 are provided in the groove 26. All steam nozzles 27 are arranged facing upwards and are connected to an external air pump. The steam nozzles 27 are used to preheat the lower surface of the cotton knitted blanket. Specifically, the steam passes through the perforated plate 28 and comes into contact with the lower surface of the cotton knitted blanket to preheat it, so that the cotton knitted blanket can be preheated from all directions, further improving the preheating effect.

[0032] Reference Figure 1 - Figure 4 ,as well as Figure 19 - Figure 20 The roller pressing module is provided with a rapid cooling module on one side, and the rapid cooling module includes a base shell 29 arranged along the width direction of the platform 1. The base shell 29 is provided with a cooling pipe 30 and an adsorption pipe 31. The cooling pipe 30 is located between the adsorption pipe 31 and the roller pressing module. The outlet end of the cooling pipe 30 is provided with a first cover 32, and the inlet end of the adsorption pipe 31 is provided with a second cover 33. The rapid cooling module is designed to quickly cool the heated cotton knitted blanket, instantly freezing its flattened state and forcibly fixing the fibers or adhesive layer, thus stabilizing the ironed state of the cotton knitted blanket. Specifically, cooling pipe 30 is connected to an external pump, which injects dry, cold air into cooling pipe 30. The cold air is all within the first cover 32 and acts on the surface of the cotton knitted blanket. Figure 20 As shown, the cotton knitted blanket moves to the left while being cooled by the cold air. Under the action of the cotton knitted blanket moving to the left, the gas after heat exchange is brought into the second cover 33. At the same time, the second cover 33 extracts the gas after heat exchange. The adsorption pipe 31 is connected to an external negative pressure pump, which can continuously and stably extract the gas from the base shell 29.
