Description

Technical Field

[0001] This utility model relates to the field of knitted fabric processing technology, and more specifically, to a steam setting device for knitted fabrics. Background Technology

[0002] After weaving, knitted fabrics have a loose fiber structure and poor overall flatness, making them prone to wrinkles, width fluctuations, and dimensional instability. They must undergo a steam setting process for moist heat shaping to reorganize and reposition the internal fibers, thereby improving the flatness, structural stability, and subsequent quality of the knitted fabric. Therefore, steam setting equipment has become an indispensable core processing equipment in the knitted fabric production line.

[0003] Currently, most traditional steam setting equipment for knitted fabrics on the market adopts a fixed fabric conveyor structure combined with a fixed steam jet method. It relies on the conveyor mechanism to drive the fabric to move continuously and completes the setting process by directly spraying steam onto the fabric surface. The structure is simple and the function is limited, making it difficult to adapt to the setting production needs of knitted fabrics of various specifications.

[0004] In actual operation, traditional setting equipment has certain problems: On the one hand, the fabric lacks flexible support and adaptive tension control during continuous fabric feeding, and cannot adapt the conveying tension in real time according to different materials and weights of knitted fabrics, which easily causes fabric deviation, local wrinkling, excessive stretching and deformation, and poor overall uniformity of fabric setting; on the other hand, traditional equipment lacks an effective gathering and circulation guiding structure after steam injection, and a large amount of steam directly dissipates and leaks outward, resulting in low thermal energy utilization, high production energy consumption, and the inability to form a stable steam covering environment in the fabric feeding area, leading to inconsistent fabric setting effects; at the same time, conventional equipment lacks a preheating treatment stage, and the fabric directly enters the high-temperature steam area, where the temperature difference between hot and cold easily generates internal stress, further affecting the quality of the finished knitted fabric. Therefore, we urgently need a steam setting device for knitted fabrics to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a steam setting device for knitted fabrics. By arranging layered guide roller groups, a steam guiding and collecting structure, and a preheating and tension adjustment mechanism, the device enables the smooth conveying of knitted fabrics and uniform steam setting on both sides, thereby reducing steam energy consumption, avoiding internal stress and deformation wrinkles in the fabric, and adapting to the setting and processing needs of knitted fabrics of various specifications.

[0006] According to a first aspect of this utility model, a steam setting device for knitted fabric is provided, comprising a frame and a conveyor belt symmetrically mounted on the frame for transporting fabric. A mounting frame is fixedly connected to the frame, forming a steam chamber between the mounting frame and the conveyor belt. The device also includes uprights symmetrically mounted on the mounting frame, with guides symmetrically and rotatably arranged on the uprights for transporting the fabric. Each guide includes a first guide group symmetrically arranged within the steam chamber, the first guide group consisting of two first rollers. The uprights are arranged in an X-shape, and mounting rods are rotatably connected to each of the four corners of the uprights. The end is provided with a meshing tooth, and the two ends of the first roller are respectively rotatably connected to the side of the corresponding mounting rod. The two sets of the first guide groups are respectively set in the gas covering area of ​​the corresponding guide hood to form a flexible support area for the fabric in the gas covering area. The steam chamber is provided with two sets of guide hoods for spraying steam. One set of guide hoods is fixedly installed on the top wall of the mounting frame, and the other set of guide hoods is fixedly installed between the two sets of conveyor belts and connected to the frame. Both sets of guide hoods are connected to the air supply unit in the frame through the first transmission pipe. The upright is fixedly installed with a guide for forming steam return.

[0007] Optionally, the upright frame has symmetrically rotating gears adapted to meshing teeth. The gears are located between two sets of mounting rods and mesh with the meshing teeth on the two sets of corresponding mounting rods. The upright frame is symmetrically mounted with drive motors, and the output end of the drive motors is connected to the corresponding gears. When the drive motor drives the gears to work, the gears drive the mounting rods on both sides to swing synchronously in opposite directions around their hinge points through meshing teeth.

[0008] Optionally, a second guide group is symmetrically arranged inside the steam chamber. The second guide group consists of two second rollers. Guide frames are symmetrically installed on the mounting frame, with two guide frames on each side. The upright frame is located between the two guide frames. A sliding groove is provided on the guide frame, and two sets of moving blocks are slidably arranged in the sliding groove. The two ends of the second rollers are rotatably connected to the corresponding moving blocks. First hydraulic rods for driving the moving blocks are symmetrically installed on the guide frame. One set of first hydraulic rods is connected to the upper moving block, and the other set of first hydraulic rods is connected to the lower moving block. When the two sets of first hydraulic rods are working, the two sets of moving blocks move relative to each other or move away from each other to form a tension control zone for the fabric.

[0009] Optionally, the guide includes symmetrically mounted gas collecting hoods on the upright frame. The longitudinal section of both sets of gas collecting hoods is trapezoidal, and the short sides of the two sets of gas collecting hoods are arranged opposite each other, with their long sides corresponding to the gas outlet of the guide hood to form a steam return channel. The short sides of the gas collecting hoods are arranged in a rectangular array with exhaust holes, and a fabric passage cavity is formed between the two sets of gas collecting hoods. When the steam output from the guide hood is guided through the gas collecting hood and exhaust holes, a steam encapsulation area is formed in the fabric passage cavity.

[0010] Optionally, support rollers are symmetrically installed on both sets of gas collection hoods to support the fabric.

[0011] Optionally, a first auxiliary roller is fixedly connected to one side of the mounting frame via a second hydraulic rod, and two sets of second auxiliary rollers are fixedly installed on the other side of the mounting frame via a connecting plate, for guiding the fabric along a path.

[0012] Optionally, a preheating plate is installed in both sets of conveyor belts, and the preheating plate is connected to the air supply equipment in the frame through a transmission pipe; when the preheating plate is working, a preheating zone for the fabric is formed at the conveyor belt.

[0013] 1. According to one embodiment of this disclosure, the steam setting device for knitted fabrics can preheat and soften the fabric during the fabric conveying process by setting a preheating plate inside the conveyor belt, effectively eliminating residual internal stress from the knitted fabric weaving; at the same time, it is equipped with a swingable adjustable first roller and a sliding adjustable second roller, and uses gear and tooth meshing transmission and a first hydraulic rod tension control structure to adapt to knitted fabrics of different widths and weights, maintains the fabric conveying tension evenly throughout the process, effectively prevents the fabric from running off-center, local slack, excessive stretching and surface wrinkling and deformation, and greatly improves the stability of fabric conveying and the processing adaptability range.

[0014] 2. According to one embodiment of this disclosure, the steam setting device for knitted fabric achieves simultaneous steam setting on both sides of the fabric by symmetrically arranging guide hoods on the upper and lower sides. Combined with the guiding and converging effect of the trapezoidal gas collecting hood on the upright frame, a stable steam return channel can be formed, reducing the disorderly dispersion and leakage of high-temperature steam. Furthermore, combined with the rectangular array of exhaust holes on the gas collecting hood, a uniform steam coverage area is formed in the fabric passage cavity between the two sets of gas collecting hoods, allowing the fabric to fully contact the high-temperature steam, resulting in more uniform and thorough setting. This not only improves the flatness and dimensional stability of the knitted fabric, but also increases the thermal energy utilization rate and reduces the energy consumption of the equipment.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figure 1-8 As shown, a steam setting device for knitted fabric includes a frame 1 and conveyor belts 2 symmetrically mounted on the frame 1 for transporting fabric. A mounting frame 3 is fixedly connected to the frame 1, and a steam chamber 4 is formed between the mounting frame 3 and the conveyor belts 2. Preheating plates 23 are installed in both sets of conveyor belts 2, and the preheating plates 23 are connected to the air supply equipment in the frame 1 through a transmission pipe. When the preheating plates 23 are working, a preheating zone for the fabric is formed at the conveyor belts 2.

[0031] Here, the frame 1 serves as the main load-bearing structure of the entire machine, stably supporting the conveyor belt 2, mounting frame 3, and other functional components of the equipment, ensuring the overall assembly strength and operational stability of the equipment. The conveyor belt 2 is symmetrically arranged on the frame 1, enabling continuous and stable conveying of knitted fabrics. The mounting frame 3 is fixed above the frame 1 and works in conjunction with the conveyor belt 2 to form the steam chamber 4, providing an independent and sealed space for internal steam setting operations.

[0032] Furthermore, the preheating plate 23 is built into the two sets of conveyor belts 2, relying on the original conveying path layout of the conveyor belts 2, without the need to occupy additional external space for separate preheating components, resulting in a compact and reasonable overall layout. The preheating plate 23 is directly connected to the internal air supply equipment of the frame 1 through pipelines, realizing centralized heat source supply and unified control.

[0033] Furthermore, as the fabric is conveyed along the conveyor belt 2, it can be heated simultaneously by the preheating plate 23, which softens the knitted fabric fibers in advance, eliminates the internal stress remaining from the fabric weaving process, and prevents the fabric from directly entering the high-temperature steam chamber 4 and encountering temperature changes that cause shrinkage, wrinkles, and deformation defects, effectively improving the basic quality of subsequent steam setting processing.

[0034] It also includes uprights 5 symmetrically mounted on mounting frame 3. Uprights 5 are symmetrically and rotatably equipped with guides for transmitting fabric. The guides include first guide groups symmetrically arranged in steam chamber 4. The first guide group consists of two first rollers 7. Uprights 5 are arranged in an X shape. Mounting rods 8 are rotatably connected to the four corners of uprights 5. The ends of mounting rods 8 are provided with teeth 9. The two ends of the first rollers 7 are rotatably connected to the sides of the corresponding mounting rods 8. The two first guide groups are respectively set in the gas-enclosed area of ​​the corresponding guide cover 6 to form a flexible support area for the fabric in the gas-enclosed area.

[0035] Here, the upright frame 5 is symmetrically fixedly assembled on the mounting frame 3. The X-shaped overall structure has good mechanical support performance and strong resistance to deformation, and can stably support various guide and transmission components inside the steam chamber 4. Mounting rods 8 are hinged at the four corners of the upright frame 5, giving the mounting rods 8 the freedom of movement to swing and adjust around the hinged positions.

[0036] Furthermore, the first guide assembly consists of two first rollers 7, with both ends of the first rollers 7 rotatably mounted on the sides of the mounting rod 8. During fabric movement, the first rollers 7 can rotate freely, reducing sliding friction resistance during fabric conveying and preventing tearing damage to the fabric surface. The teeth 9 at the end of the mounting rod 8 provide a structural basis for subsequent mechanical transmission adjustments.

[0037] Furthermore, the two sets of first guide groups are arranged inside the gas-enclosed area formed by the guide cover 6, which can provide multi-point flexible support for the knitted fabric passing through, preventing the fabric from becoming loose and collapsing or shifting in width when it travels a long distance in the steam chamber 4. At the same time, the fabric is kept within the steam coverage of the guide cover 6 throughout the process, ensuring that the fabric is shaped and heated evenly.

[0038] A gear 10, which is adapted to the meshing teeth 9, is symmetrically rotated on the upright frame 5. The gear 10 is located between two sets of mounting rods 8, and the gear 10 meshes with the meshing teeth 9 on the two sets of corresponding mounting rods 8. A drive motor 11 is symmetrically mounted on the upright frame 5, and the output end of the drive motor 11 is connected to the corresponding gear 10. When the drive motor 11 drives the gear 10 to work, the gear 10 drives the mounting rods 8 on both sides to swing synchronously in opposite directions around their hinge points through the meshing teeth 9.

[0039] Here, gear 10 is rotatably mounted on the stand 5 and positioned between the two sets of mounting rods 8. Gear 10 meshes with the teeth 9 at the ends of the mounting rods 8 on both sides. The transmission layout of single gear linkage with double-sided components is adopted, which has a high degree of structural integration and occupies little internal space in the steam chamber 4.

[0040] Furthermore, the drive motor 11 is fixedly mounted on the support frame 5 and its output end is directly connected to the gear 10. The power transmission path is short, and there is no need to add intermediate transmission transition components. The power transmission loss is low, and the start-stop and speed control response is sensitive and reliable.

[0041] Furthermore, during the rotation of the drive motor 11 and the drive gear 10, the meshing gear 9 can drive the mounting rods 8 on both sides to swing synchronously in opposite directions around their own hinge positions, thereby synchronously adjusting the relative position of the first roller 7, achieving centered support and adaptation for knitted fabrics of different widths and materials, maintaining balanced force on the fabric conveying, and effectively avoiding fabric deviation and unilateral stretching deformation problems.

[0042] A second guide group is symmetrically arranged inside the steam chamber 4. The second guide group consists of two second rollers 12. Guide frames 13 are symmetrically installed on the mounting frame 3. There are two guide frames 13 on each side. The upright frame 5 is located between the two guide frames 13. A sliding groove 14 is opened on the guide frame 13. Two sets of moving blocks 15 are slidably arranged in the sliding groove 14. The two ends of the second rollers 12 are rotatably connected to the corresponding moving blocks 15. First hydraulic rods 16 for driving the moving blocks 15 are symmetrically installed on the guide frame 13. One set of first hydraulic rods 16 is connected to the upper moving block 15, and the other set of first hydraulic rods 16 is connected to the lower moving block 15. When the two sets of first hydraulic rods 16 are working, the two sets of moving blocks 15 move relative to each other or move away from each other to form a tension control zone for the fabric.

[0043] Here, the second guide group is symmetrically arranged inside the steam chamber 4, and works in conjunction with the first guide group to form a multi-layer, multi-directional roller guide structure, which can meet the process requirements of multi-path bypass and reversing conveying of knitted fabrics. The guide frames 13 are fixed in pairs on the mounting frame 3 and are arranged on both sides of the upright frame 5, with a regular overall layout and symmetrical force distribution.

[0044] Furthermore, a sliding groove 14 is provided on the surface of the guide frame 13. The sliding groove 14 can form a linear limiting guide for the internally assembled moving block 15, ensuring that the moving block 15 can only slide smoothly along the preset trajectory of the sliding groove 14, and avoiding the moving block 15 from deviating and getting stuck during the sliding process. The two ends of the second roller 12 are rotatably connected to the moving block 15, and can move synchronously with the moving block 15 while maintaining a free rotation state.

[0045] Furthermore, the first hydraulic rods 16 arranged at the top and bottom independently drive the corresponding moving blocks 15 to move towards or away from each other, which can flexibly adjust the distance between the upper and lower second rollers 12, precisely change the tension of the knitted fabric during its movement, adapt to the tension adjustment needs of knitted fabrics with different weights and elasticities, form a stable and controllable fabric tension control area, and eliminate processing defects such as the fabric being too loose and wrinkling or too tight and stretching.

[0046] The steam chamber 4 is equipped with two sets of guide hoods 6 for steam injection. One set of guide hoods 6 is fixedly installed on the top wall of the mounting frame 3, and the other set of guide hoods 6 is fixedly installed between the two sets of conveyor belts 2 and connected to the frame 1. Both sets of guide hoods 6 are connected to the air supply unit in the frame 1 through the first transmission pipe.

[0047] Here, two sets of guide covers 6 are fixed at the top and bottom positions respectively on the top wall of the mounting frame 3 and the upper part of the frame 1. The corresponding upper and lower positions can spray high-temperature steam towards the upper and lower surfaces of the knitted fabric to achieve synchronous steam setting of the fabric on both sides.

[0048] Furthermore, the guide cover 6 is fixed on the mounting frame 3 and the frame 1 respectively. The mounting point is firm and not easily displaced by the steam flow and fabric vibration, so as to keep the steam jet direction and the fabric travel path accurately aligned at all times.

[0049] Furthermore, the two sets of guide covers 6 are connected to the internal air supply unit of the frame 1 through the first transmission pipe to achieve centralized and unified steam delivery and distribution. The steam supply pressure is stable and the flow rate is uniform, which can continuously output uniform high-temperature steam into the steam chamber 4, ensuring a stable steam atmosphere during the fabric setting process and improving the overall setting uniformity.

[0050] A guide component for forming steam reflux is fixedly installed on the upright frame 5. The guide component includes a steam collection hood 17 symmetrically installed on the upright frame 5. The longitudinal section of the two sets of steam collection hoods 17 is trapezoidal. The short sides of the two sets of steam collection hoods 17 are arranged opposite each other, and their long sides correspond to the air outlet of the guide hood 6 to form a steam reflux channel. The short sides of the steam collection hoods 17 are arranged in a rectangular array with exhaust holes 18. A fabric passage cavity is formed between the two sets of steam collection hoods 17. When the steam output from the guide hood 6 is guided through the steam collection hoods 17 and exhaust holes 18, a steam encapsulation area is formed in the fabric passage cavity.

[0051] Here, the gas collecting hood 17 is symmetrically and fixedly mounted on the support frame 5. Its central installation position on the support frame 5 is located in the core area of ​​the steam chamber 4, facilitating the reception of the steam flow ejected from the guide hood 6. The gas collecting hood 17 adopts a trapezoidal cross-section structure, possessing the function of guiding and converging natural gas flow.

[0052] Furthermore, the large end of the gas collecting hood 17 is set to correspond to the gas outlet end of the guide hood 6, and the small ends are arranged opposite each other. This can collect and guide the steam ejected from the guide hood 6, naturally forming a regular steam return channel, reducing the disorderly dispersion and leakage of steam into the outer space of the steam chamber 4, and improving the efficiency of thermal energy utilization.

[0053] Furthermore, the small end of the gas collection hood 17 is arrayed with exhaust holes 18. The steam collected by the gas collection hood 17 can be evenly overflowed into the fabric passage cavity between the two sets of gas collection hoods 17 through the exhaust holes 18, forming a stable and sealed steam-covered area around the fabric passage cavity, so that the knitted fabric passing through it is fully soaked and shaped by high-temperature steam, and the shaping effect is uniform and long-lasting.

[0054] Support rollers 19 are symmetrically installed on both sets of air collection hoods 17 to support the fabric. A first auxiliary roller 21 is fixedly connected to one side of the mounting frame 3 via a second hydraulic rod 20, and two sets of second auxiliary rollers 22 are fixedly installed on the other side of the mounting frame 3 via a connecting plate to guide the fabric.

[0055] Here, the support rollers 19 are symmetrically installed outside the air collection hood 17, which can provide auxiliary support for the knitted fabric passing around the air collection hood 17, make up for the gap between the roller support points, and prevent the fabric from hanging down and touching the surface of the air collection hood 17, causing scratch damage.

[0056] Furthermore, the first auxiliary roller 21 is connected to the mounting frame 3 via the second hydraulic rod 20. The second hydraulic rod 20 can drive the first auxiliary roller 21 to achieve fine-tuning of its position, adapting to the fabric feeding requirements of different stitching heights and possessing a certain degree of adaptability and adjustment capability. The second auxiliary roller 22 is fixed to the other side of the mounting frame 3 via a connecting plate, ensuring a stable mounting structure and fixed guide angle.

[0057] Furthermore, the first auxiliary roller 21 and the two sets of second auxiliary rollers 22 are placed on both sides of the equipment to form a complete guide layout for material feeding and discharging. This can regulate and limit the path of the knitted fabric as it enters and leaves the steam chamber 4, preventing the fabric from deviating from its position at the inlet and outlet, and ensuring that the fabric is smoothly conveyed along the preset trajectory throughout the entire process.

[0058] In this invention, the knitted fabric is first conveyed by the conveyor belt 2 on the feeding side of the device. The preheating plate 23 in the conveyor belt 2 preheats the fabric in contact with it, eliminating the internal stress generated during weaving. After preheating, the fabric first enters the shaping section in the steam chamber 4 through the first auxiliary roller 21 on the right side of the mounting frame 3, and then moves along a set path: the fabric first passes around the second roller 12 and support roller 19 of the upper second guide group, and then moves to the first roller 7 on the upper side of the upright frame 5. At this time, the surface of the fabric is facing the steam outlet of the upper guide cover 6, receiving the first high-temperature steam shaping. The drive motor 11 can drive the gear 10 to rotate, and through meshing with the meshing teeth 9 at the end of the mounting rod 8, it drives the mounting rods 8 on both sides to swing synchronously in opposite directions, adjusting the position of the first roller 7. In conjunction with the first hydraulic rod 16 on the guide frame 13, it drives the moving block 15 in the sliding groove 14 to adjust the position of the second roller 12, realizing the adaptive control of the fabric tension and avoiding deviation or stretching deformation. Then the fabric moves from another... The fabric exits from the upper first roller 7 on the side, then passes through the support roller 19 and the second roller 12 in sequence, and is then guided by the inner second auxiliary roller 22 to enter the fabric passage cavity between the two sets of gas collecting hoods 17. The trapezoidal structure of the gas collecting hood 17 gathers the steam ejected from the guide hood 6 to form a return channel. The exhaust hole 18 on the short side evenly sprays steam into the cavity to form a stable steam-enclosed environment for secondary shaping of the fabric. After the fabric passes through the fabric passage cavity, it passes through the second roller 12 and the support roller 19 of the lower second guide group, and then moves to the first roller 7 on the lower side of the stand 5. At this time, the other side of the fabric faces the steam outlet of the lower guide hood 6 to receive the third high-temperature steam shaping. The shaped fabric exits from the lower first roller 7, passes through the support roller 19 and the second roller 12 on the other side in sequence, and is then guided by the outer second auxiliary roller 22 to enter the conveyor belt 2 on the discharge side of the device. It is then conveyed away from the device by the conveyor belt 2, completing the entire steam shaping process of the knitted fabric.
