Description

Technical Field

[0001] This utility model relates to the field of textile equipment, and more specifically, it relates to a dual-purpose fabric feeder for knitting and weaving. Background Technology

[0002] Fabric feeders are devices used in textile printing and dyeing enterprises to transport fabrics. They are primarily used to smoothly and neatly convey the fabric to subsequent processing equipment to ensure the smooth operation of textile printing and dyeing processes. Their structure generally includes:

[0003] Frame structure: This is the supporting part of the fabric rack. It is usually made of metal materials, such as steel, and has a certain strength and stability to support the weight of the fabric and other components.

[0004] Fabric guide rollers: Installed on the main frame, in varying numbers, and rotatable. Their function is to guide the fabric, enabling it to move along a predetermined path, while also providing support and reducing friction during fabric transport.

[0005] Correction structure: Used to detect the position of the fabric on the feed roller and correct its alignment through corresponding actions, ensuring the fabric is always in the correct centered position and preventing it from slipping and affecting subsequent processing. Common correction structures include correction movement units, correction rollers, and detection probes.

[0006] Fabric spreading structure: Located near the fabric inlet, it is mainly used to spread the fabric out, preventing folds and wrinkles and facilitating subsequent processes. For example, the spreading roller spreads the fabric through its split threads. On the contact surface between the fabric and the split threads, the rotation of the split threads expands outward, thus spreading the fabric outward.

[0007] Power unit: Some fabric feeders are equipped with motors or other power units to provide power for the rotation of the fabric feed rollers or the movement of other components, enabling smoother fabric transport. For example, a belt pulley drive mechanism rotates the first drive roller, which in turn drives the other fabric feed rollers to rotate, thus achieving fabric transport.

[0008] Tension adjustment device: It can adjust the tension of the fabric during the conveying process, so that the fabric maintains the appropriate tightness and prevents the fabric from wrinkling due to being too loose or stretching and deforming due to being too tight.

[0009] Its working principle is as follows: The fabric is placed at the starting position of the fabric feeding frame, and is gradually conveyed forward by the rotation of the fabric guide roller. The power unit drives the active fabric guide roller to rotate, and the friction between the active fabric guide roller and the fabric drives the fabric to move. At the same time, the passive fabric guide roller plays an auxiliary support and guiding role, so that the fabric moves smoothly along the predetermined path. The detection probe monitors the position of the fabric edge or center in real time. When the detection probe detects that the fabric deviates from the center position, it transmits a signal to the controller. The controller controls the movement of the correction unit, which drives the correction roller to move left or right or rotate, applying a lateral force to the fabric and bringing it back to the appropriate center position. The fabric spreading roller in the spreading structure contacts the fabric through the split thread. When the spreading roller rotates, the rotation direction of the split thread expands outward, thereby spreading the fabric. The shape and spacing of the split thread are reasonably designed, which can effectively spread out folded or wrinkled fabric step by step, so that it enters the subsequent process in a flat state.

[0010] However, existing fabric feeders are often only suitable for processing one type of fabric: knitted or woven. Knitted fabrics are formed by interlocking loops, are highly elastic and extensible, and are easily stretched and deformed under stress (such as horizontal or vertical extension). They are also prone to curling and wrinkling when relaxed. Woven fabrics, on the other hand, are formed by vertically interlacing warp and weft yarns, have a stable structure, low elasticity, and are not easily stretched. However, they are prone to wrinkling or warp and weft yarn misalignment due to uneven tension. Therefore, knitted fabrics need to avoid excessive stretching, requiring extremely precise tension adjustment of the fabric feeder. Woven fabrics, on the other hand, require sufficient tension to maintain flatness. The tension requirements of the two are almost opposite, resulting in a contradiction in the compatibility of fabric feeders. Specifically, the tension of knitted fabrics needs to be controlled within a very low range (usually 0.5–2 N / cm) and needs to be dynamically adjusted in real time (such as automatically reducing pressure as the fabric roll diameter changes). Otherwise, the loops will be stretched, leading to unstable fabric dimensions. Woven fabrics require high tension (2-5 N / cm) and must be kept constant to ensure that the warp and weft yarns are aligned neatly and to avoid misalignment of patterns during printing and dyeing. Existing tension adjustment systems for fabric feeders cannot simultaneously meet the requirements of "low tension dynamic control" (knitting) and "high tension constant control" (woven fabrics).

[0011] Therefore, a new solution is needed to address this problem. Utility Model Content

[0012] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric feeder that can be used for both knitting and weaving.

[0013] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dual-purpose fabric feeder for knitting and weaving, comprising:

[0014] frame;

[0015] Flattening rollers are used to initially unfold knitted fabric from a fabric rolling machine;

[0016] The shear force correction mechanism is located downstream of the flattening roller and corrects the knitted fabric once through lateral shear force.

[0017] The knitted fabric edge detection mechanism is located downstream of the shear force correction mechanism. It monitors the edge position of the knitted fabric in real time and generates a feedback signal. The shear force correction mechanism upstream then corrects the subsequent knitted fabric.

[0018] The tension relief cavity is located downstream of the knitted fabric edge detection mechanism and is used to eliminate the tension generated in the knitted fabric during the conveying process.

[0019] The first tensioning unit is located downstream of the tension release cavity, providing a tension of 0.5 to 2 N / cm to the knitted fabric;

[0020] The spoke correction roller is located downstream of the first tensioning unit and is used for secondary correction of knitted or woven fabrics.

[0021] The universal edge detection mechanism is located downstream of the spoke correction roller. It monitors the edge position of the knitted or woven fabric in real time and generates a feedback signal. It then corrects the subsequent fabric through the upstream spoke correction roller.

[0022] Woven fabric rollers are used to hold rolls of woven fabric.

[0023] The second tensioning unit is located between the woven fabric roller and the spoke correction roller to provide a tension of 2 to 5 N / cm for the woven fabric.

[0024] The spoke correction roller serves as a shared correction component for both knitted and woven fabrics.

[0025] The present invention is further configured such that the spoke straightening roller comprises:

[0026] The rotating shaft is rotatably mounted on the frame and driven by a motor;

[0027] Several axially sliding spokes are evenly distributed around the outer periphery of the rotating shaft, and the inner side of the spokes is connected to the rotating shaft through a slider-guide rail pair;

[0028] The swing arm assembly includes a pair of swing arms rotatably connected to the frame and located at both ends of the pivot shaft. The swing arms are connected to the ends of the spokes via a universal joint structure. The movable ends of the swing arms are driven by a linear reciprocating drive mechanism.

[0029] The linear reciprocating drive mechanism drives the swing arm to swing according to the signal from the universal edge detection mechanism. The swing arm drives all the spokes to generate axial displacement synchronously through the universal joint structure. As a result, the spokes form a spiral surface with a controllable angle to the fabric conveying direction during rotation, generating a dynamic lateral force for lateral correction of the fabric.

[0030] The present invention is further configured such that both the knitted fabric edge detection mechanism and the general edge detection mechanism include photoelectric sensors, and the deviation is calculated in real time by a PLC.

[0031] The present invention is further configured such that the front and rear sidewalls of the tension release cavity are inclined toward the interior of the cavity, forming a gradually narrowing channel structure.

[0032] The present invention is further configured such that the shear force correction mechanism includes:

[0033] The first and second straightening rollers, arranged in parallel intervals, are used to form a conveying channel for the fabric to pass through.

[0034] Two swing brackets are rotatably connected to the frame and correspond one-to-one with the ends of the first and second correction rollers. The swing brackets can swing around the hinge point with the frame.

[0035] A cylinder drive assembly is connected to one of the swing brackets to drive the swing bracket to swing, and through the linkage of the first correction roller and the second correction roller, drives the other swing bracket to swing synchronously.

[0036] The present invention is further configured such that: a plurality of conveying rollers are rotatably connected to the frame and disposed between the second tensioning unit and the spoke correction roller, and the plurality of conveying rollers are used to convey woven fabric.

[0037] The present invention is further configured such that the distance between the second tensioning unit and the spoke correction roller is less than 50cm.

[0038] The present invention is further configured such that the distance between the universal edge detection mechanism and the spoke correction roller is less than 20cm.

[0039] The present invention is further configured such that the distance between the knitted fabric edge detection mechanism and the shear force correction mechanism is less than 20cm.

[0040] In summary, this utility model has the following beneficial effects: Compatibility with two fabrics: By using zoned tensioning units and different functional correction mechanisms, the incompatibility between knitted and woven fabrics is resolved, allowing one set of equipment to meet diverse processing needs. Precise tension control: The first tensioning unit provides low tension (0.5–2 N / cm) for knitted fabrics and dynamically adjusts it; the second tensioning unit provides high tension (2–5 N / cm) for woven fabrics and maintains it constant, ensuring fabric processing quality. Efficient correction and flattening of knitted fabrics: The shear force correction mechanism works in conjunction with the spoke correction roller to achieve two-stage correction. Combined with the flattening roller and tension release cavity, it effectively avoids fabric wrinkles and deviation, improving the flatness of the fabric conveying. Attached Figure Description

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0048] A dual-purpose fabric feeder for both knitting and weaving, such as Figure 1 and Figure 2 As shown, the system includes a frame 1, which is welded from high-strength steel, possessing good strength and stability, and serving as the base for installing various components. Along the fabric conveying direction (from the feed to the subsequent processing equipment), the following components are arranged in sequence: a flattening roller 2, a shear force correction mechanism 11, a knitted fabric edge detection mechanism 3, a tension release cavity 4, a first tensioning unit 5, a spoke correction roller 6, and a general edge detection mechanism 7. The woven fabric roller 8 is also arranged on the front side of the frame 1, and a second tensioning unit 9 is set between it and the spoke correction roller 6. Optional auxiliary components such as a rotatably connected conveyor roller 10 can also be installed on the frame 1 as needed.

[0049] like Figure 1 and Figure 3As shown, the flattening roller 2 is mounted on the frame 1 in an arc shape. When the knitted fabric 23 is output from the fabric cart and comes into contact with the flattening roller 2, the fabric (or roll) runs in contact with the arc-shaped flattening roller 2. Due to the arc-shaped structure of the roller surface, the running path length and linear speed of different parts of the fabric are different. Because of the arc-shaped structure, the running path of the fabric is longer on both sides, which will extend to both sides, thus producing a stretching effect on the fabric to both sides. This initially unfolds the knitted fabric 23, which may be folded or wrinkled, providing the basic conditions for subsequent processing.

[0050] like Figure 1 and Figure 3 As shown, the shear force correction mechanism 11 includes: a first correction roller 12 and a second correction roller 13 arranged in parallel at intervals. Both are made of rubber-coated metal rollers. The rubber layer increases the friction with the fabric, and the metal rollers ensure strength, forming a conveying channel for the fabric to pass through; two swing brackets 14, which are rotatably connected to the frame 1 respectively, and each corresponds to the end of the first correction roller 12 and the second correction roller 13. The swing brackets 14 can swing around the hinge point with the frame 1; a cylinder drive assembly 15 is connected to one of the swing brackets 14. Specifically, the moving part of one swing bracket 14 is connected to the frame 1 through a cylinder. The cylinder, the frame 1, and the swing bracket 14 are all rotatably connected. The cylinder extends and retracts to drive the swing bracket 14 to swing. The first correction roller 12 and the second correction roller 13 are linked together to drive the other swing bracket 14 to swing synchronously. When the fabric conveying shows a deviation trend, the subsequent knitted fabric edge detection mechanism 3 detects it and generates a feedback signal. The cylinder drives the swing bracket 14 to swing, forming a shear force difference in the transverse direction of the fabric (perpendicular to the conveying direction). This shear force difference acts on the deviated fabric, generating a transverse correction force, pulling the fabric back to the preset conveying path, and realizing the correction. The shear force correction mechanism 11 and the knitted fabric edge detection mechanism 3 form a closed-loop control circuit. The shear force direction and force are adjusted in real time according to the detection data. In actual operation, if the fabric deviates to the left, the swing bracket drives the two rollers to adjust the angle. The transverse friction force of the right roller on the fabric is greater than that on the left. Through the shear force difference, the fabric is pushed to the right to return to the center, completing the initial large-scale correction operation of the knitted fabric 23, laying a good foundation for the subsequent secondary correction.

[0051] like Figure 1As shown, the knitted fabric edge detection mechanism 3 uses a photoelectric sensor and is installed at the corresponding position on the frame 1, downstream of the shear force correction mechanism 11. The distance between the knitted fabric edge detection mechanism 3 and the shear force correction mechanism 11 is less than 20cm; in this embodiment, 15cm is used to ensure timely detection. The photoelectric sensor emits light to detect the edge position of the knitted fabric 23, converting the light signal into an electrical signal. The PLC (Programmable Logic Controller) calculates the fabric deviation in real time. When the deviation exceeds a set threshold, a feedback signal is immediately generated and sent to the drive component of the shear force correction mechanism 11 to trigger the correction action, ensuring the accurate conveying position of the knitted fabric 23.

[0052] like Figure 1 As shown, the tension release channel 4 is welded from metal plates, with the front and rear sidewalls inclined inwards to form a gradually narrowing channel structure. After one correction, the knitted fabric 23 enters the tension release channel 4. The gradually narrowing structure releases the internal tension of the fabric as it passes through. The principle is to utilize the changing channel space to gradually relax the fabric during transport, eliminating the tension generated by the initial transport and correction, and preventing the knitted fabric 23 from stretching and deforming due to tension concentration. Before entering the channel, the fabric experiences localized tension concentration; after being transported through the gradually narrowing channel, the tension is released evenly, and the fabric returns to its natural state.

[0053] like Figure 1 As shown, the first tensioning unit 5 includes: a drive assembly, a tension roller group consisting of two parallel tension rollers 16, and a rotating frame 17 serving as the mounting base for the tension roller group. The rotating frame 17 can rotate within a certain angle range around its own axis 18 to adjust the relative position and wrap angle between the tension roller group and the fabric. The drive assembly uses a servo motor with a reduction transmission mechanism (such as gear transmission or synchronous belt transmission) connected to the rotating frame 17 to drive the two tension rollers 16 to rotate synchronously. By adjusting the swing angle of the rotating frame 17, the wrap angle between the fabric and the tension roller group is changed, thereby controlling the tension. The knitted fabric 23 is passed through the two tension rollers 16 in an S-shaped winding manner. The control system sends a command to the drive assembly according to the tension requirements of the knitted fabric 23 (0.5~2N / cm). The first tensioning unit 5 reduces the wrap angle by controlling the swing angle of the rotating frame 17 to provide a precise tension of 0.5~2N / cm for the knitted fabric 23. In this embodiment, it provides a tension of 1N / cm to achieve low-tension dynamic control, protect the coil structure of the knitted fabric 23, and avoid stretching deformation.

[0054] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the spoke correction roller 6 comprises the following structure: a rotating shaft 18 is a steel cylindrical structure, rotatably mounted on the frame 1 and driven by a servo motor; several axially sliding spokes 19 are evenly distributed around the outer periphery of the rotating shaft 18, and the inner side of the spokes 19 is connected to the rotating shaft 18 through a slider-guide pair and can achieve axial sliding; the swing arm assembly includes a pair of steel swing arms 20 rotatably connected to the frame 1 and located at both ends of the rotating shaft 18, the swing arms 20 are connected to the ends of the spokes 19 through a universal joint structure 21 (using a ball joint to ensure flexible rotation and force transmission), and the movable end of the swing arm 20 is driven by a linear reciprocating drive mechanism 22 (such as a servo cylinder or ball screw structure). In this embodiment, the linear reciprocating drive mechanism 22 uses a servo cylinder. For the knitted fabric 23, after passing through the first tensioning unit 5, it is conveyed to the spoke correction roller 6. A general edge detection mechanism 7 detects the edge position of the fabric. If there is a deviation, the linear reciprocating drive mechanism 22 drives the swing arms 20 to swing according to the detection signal. The swing arm 20 drives all spokes 19 to synchronously generate axial displacement through the universal joint structure 21, so that the spokes 19 form a spiral surface with a controllable angle to the fabric conveying direction during rotation, generating dynamic lateral force to perform secondary correction on the knitted fabric 23. For the woven fabric 24, after being output from the woven fabric roller 8 and passing through the second tensioning unit 9, it is conveyed to the spoke correction roller 6. When the universal edge detection mechanism 7 detects the deviation, it also corrects the deviation by using the lateral force of the spiral surface through the action of the spokes 19, thus realizing the shared correction function.

[0055] like Figure 1 and Figure 2 As shown, the general edge detection mechanism 7 includes a photoelectric sensor, which is mounted on the frame 1 and located downstream of the spoke correction roller 6, at a distance of less than 20cm. In this embodiment, 15cm is used to ensure timely detection. Its working principle is the same as that of the knitted fabric edge detection mechanism 3. The photoelectric sensor detects the edge position of the knitted or woven fabric 24, and the PLC calculates the deviation in real time, generating a feedback signal that is sent to the linear reciprocating drive mechanism 22 of the spoke correction roller 6 to correct the fabric deviation in a timely manner. Regardless of the type of fabric, it can accurately monitor and provide feedback.

[0056] like Figure 2 As shown, the woven fabric roller 8 is made of steel or aluminum alloy and is used to hold the woven fabric roll 24. It can be rotatably mounted on the frame 1 via bearings, facilitating the rotation and feeding of the fabric roll. After the fabric roll is placed, the woven fabric 24 is output from the roller and enters subsequent components such as the second tensioning unit 9.

[0057] like Figure 2As shown, the second tensioning unit 9 has the same structure as the first tensioning unit 5. It is located between the woven fabric roller 8 and the spoke correction roller 6, at a distance of less than 50cm from the spoke correction roller 6. In this embodiment, 30cm is used, which allows for immediate correction and entry into subsequent processing equipment, avoiding tension fluctuations. The second tensioning unit 9 provides a constant tension of 2-5N / cm for the woven fabric 24. In this embodiment, it provides a tension of 3N / cm. After the woven fabric 24 is output from the roller, the tension of the fabric is controlled by the second tensioning unit 9, ensuring that the warp and weft yarns are aligned neatly and preventing misalignment of the printing and dyeing patterns due to uneven tension. This meets the requirements of high tension and constant control for the woven fabric 24.

[0058] like Figure 2 As shown, several conveying rollers 10 are set between the second tensioning unit 9 and the spoke correction roller 6 on the frame 1. The conveying rollers 10 are mounted on the frame 1 through bearing seats. When the woven fabric 24 passes through the conveying rollers 10, the conveying rollers 10 support the fabric to ensure stable fabric tension and smooth conveying.

[0059] Knitted fabric 23 conveying process: fabric cart → flattening roller 2 (initial flattening) → shear force correction mechanism 11 (first correction) → knitted fabric edge detection mechanism 3 (detection feedback, assisting first correction) → tension release cavity 4 (releasing tension) → first tensioning unit 5 (providing low tension of 0.5~2N / cm and dynamically adjusting) → spoke correction roller 6 (secondary correction) → general edge detection mechanism 7 (detection feedback, assisting secondary correction) → subsequent processing equipment.

[0060] Woven fabric 24 conveying process: Woven fabric roller 8 → Second tensioning unit 9 (provides 2~5N / cm high tension and keeps it constant) → Spoke correction roller 6 (first correction) → General edge detection mechanism 7 (detection feedback, assisting correction) → Subsequent processing equipment.

[0061] Through the above implementation methods, this dual-purpose fabric feeder for knitting and weaving can effectively meet 24 different processing needs of knitted and woven fabrics, achieve precise tension control, efficient deviation correction and flattening, ensure stable fabric delivery to subsequent processes, and improve the quality and efficiency of textile printing and dyeing processing.

[0062] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
