Description

Technical Field

[0001] The utility model relates to the field of fabric correction technology, and in particular to a fabric correction feeding device. Background Technology

[0002] With continuous technological advancements, automated garment manufacturing equipment is becoming increasingly common. Introducing automated equipment into garment factories not only significantly improves production efficiency but also ensures a high degree of consistency in product quality. However, due to the soft nature of fabrics, they are prone to shifting during the sewing process. Fabric correction devices have emerged to address this issue, ensuring that the fabric maintains the correct position and orientation throughout the sewing process. When fabric shifts due to various factors, this device uses mechanical structures to promptly correct the deviation, thereby guaranteeing the stable operation of the production line and product quality.

[0003] Currently, most existing fabric correction devices on the market simply use correction wheels or fingers to guide the fabric during sewing. However, these devices often fail to adequately consider the fabric's capacity, typically placing the gears or correction wheels used to guide the fabric in a single row. As a result, when the fabric is guided, any wrinkles or bulges have nowhere to go, easily shifting to one side. Furthermore, because the correction wheels are arranged in a row, only a portion of the fabric is guided, leaving the sides unaffected. This leads to uneven fabric distribution after correction, resulting in jagged wrinkles on the garment's surface and severely impacting its appearance.

[0004] The technical content disclosed in the Chinese patent document (Publication No.: CN215251601U, Patent Title: Fabric Correction and Feeding Auxiliary Device and its Fabric Correction Mechanism) is as follows: at least a portion of the gear extends out of the mounting hole, and a first rotary drive device is connected to the screw. The first rotary drive device drives the screw to rotate in both directions, and drives the gear to rotate in both directions, thereby correcting the fabric that comes into contact with the gear.

[0005] The patent documents above show that this correction mechanism uses gears to correct the fabric's deviation. However, the patent's illustrations reveal that the gears are arranged in a row, with no space between them to accommodate the fabric. This causes the fabric to drift or pile unevenly when it is moved, as there is nowhere for it to go. Utility Model Content

[0006] The utility model overcomes the shortcomings of the prior art and provides a fabric correction feeding device. The staggered distribution of the correction transmission group makes the transmission mechanism and transmission gap on the same axis alternately arranged, thereby realizing a more comprehensive and detailed correction operation on the fabric.

[0007] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0008] A fabric correction and feeding device includes a rotary table, with a first motor externally connected to the rotary table to achieve self-rotation of the rotary table;

[0009] The rotary seat is internally connected to a central drive structure, which includes a central rotating shaft. A second motor is externally connected to the central rotating shaft. The rotary seat is fixedly connected to a mounting center seat, which is connected to a correction transmission group. The correction transmission group includes several transmission mechanisms, which are arranged in a ring shape, with a transmission gap between each pair of transmission mechanisms.

[0010] The misaligned distribution of the correction transmission groups at both ends of the mounting base results in the transmission mechanism and transmission gap on the same axis being arranged alternately.

[0011] The transmission mechanism includes a correction belt, and the rotation of the central shaft ultimately drives the correction belt to rotate. A portion of the correction belt is exposed outside the mounting base. When the correction belt rotates, it applies a lateral pushing force to the fabric. The rotation plane of the correction belt is orthogonal to the rotation axis of the central drive structure.

[0012] The mounting base is provided with a accommodating arc groove in the middle, which is used to accommodate the fabric that is wrinkled when it is moved.

[0013] Furthermore, the central rotating shaft is connected to the central worm gear;

[0014] The transmission mechanism includes an internal gear, which meshes with a central worm gear, and the side of the internal gear away from the central worm gear meshes with an external gear.

[0015] The correction belt is sleeved on the external gear.

[0016] Furthermore, the correction belt is a round belt, and the external gear is provided with at least one embedded arc groove, into which the correction belt is fitted.

[0017] Furthermore, the transmission mechanism includes an inner rotating shaft, which is connected to an inner gear via a fourth bearing; and an outer gear is connected to an outer rotating shaft via a third bearing.

[0018] Furthermore, both sides of the mounting base are provided with several inner shaft grooves, and the first and last ends of the several inner shaft grooves are connected to form a polygonal groove, in which the inner rotating shaft is fitted.

[0019] An internal gear groove is vertically provided at the center of the inner shaft groove, and the internal gear groove is used to accommodate the internal gear.

[0020] The mounting base is provided with an outer shaft groove near the accommodating arc groove. The outer rotating shaft is fitted into the outer shaft groove. A third belt groove is provided perpendicular to the outer shaft groove. A part of the correction belt is fitted into the third belt groove.

[0021] Furthermore, the mounting base is connected to an end cap on the side away from the rotating base, the rotating base is provided with a second groove, and the end cap is provided with a first groove;

[0022] The first groove and the third groove on one side of the mounting base are directly connected to form the first correction mounting cavity. A part of the correction belt is fitted into the first correction mounting cavity, and the other part is exposed outside the rotating base and the mounting base.

[0023] The second groove and the third groove on the other side of the mounting base are directly connected to form the second correction mounting cavity. A part of the correction belt is fitted into the second correction mounting cavity, and the other part is exposed outside the rotating base and the mounting base.

[0024] Furthermore, the central shaft is connected to several second bearings, and the outer rings of the second bearings are connected to the rotating base and the end cover.

[0025] Furthermore, one end of the rotating shaft is connected to a coupling.

[0026] Furthermore, the correction belt is made of rubber.

[0027] Compared with existing technologies, the advantages of this utility model are:

[0028] 1. By setting a accommodating arc groove in the middle of the mounting base, the accumulation and damage of the fabric due to wrinkles during the correction process are avoided, ensuring the uniformity of the wrinkle distribution formed by the sewing, so that the fabric can be smoothly processed in subsequent operations, thus ensuring the normal operation of the garment equipment and the quality of fabric processing.

[0029] 2. The staggered distribution of the correction transmission group allows the transmission mechanism and transmission gap on the same axis to be arranged alternately, thereby achieving a more comprehensive and detailed correction operation on the fabric. This overcomes the limitation of traditional structures that set the power point for moving the fabric in a straight line, ensuring that the fabric is effectively corrected throughout its width. In addition, the existence of transmission gaps allows the fabric to move after being moved and forming folds, preventing excessive accumulation of fabric in a certain position. The fabric can move and adjust more freely in the transmission gaps, avoiding the impact of local accumulation on the fabric's transport and processing quality. As a result, the folds in the stitches are evenly distributed, resulting in a better appearance of the sewn fabric and improving product quality and market competitiveness.

[0037] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0038] like Figures 1 to 5 As shown, a fabric deviation correction feeding device can effectively realize the directional conveying and automatic deviation correction of fabric, improving the working efficiency of garment manufacturing equipment and the quality of fabric processing. It includes a rotary table 5, with a first motor externally connected to the rotary table 5, thereby enabling the rotary table 5 to rotate independently.

[0039] The rotary base 5 is internally connected to a central drive structure 1, which includes a central rotating shaft 101. One end of the central rotating shaft 101 is connected to a coupling 105, which in turn connects to a second motor. The coupling 105 effectively transmits power and, to a certain extent, buffers and dampens vibrations, reducing vibration and impact between the motor and the central rotating shaft 101, thus extending the service life of the components. The central rotating shaft 101 is connected to several second bearings 103, the outer rings of which are connected to the rotary base 5 and the end cover 3. The second bearings 103 reduce the frictional resistance of the central rotating shaft 101 during rotation, improving the smoothness and stability of rotation and ensuring the efficiency of power transmission.

[0040] The rotating base 5 is fixedly connected to the mounting base 4, and the mounting base 4 is connected to the correction transmission group 2. The correction transmission group 2 includes several transmission mechanisms 201, which are arranged in a ring shape, and a transmission gap is formed between every two transmission mechanisms 201. This ring shape and transmission gap design allows the fabric to contact the transmission mechanism 201 more smoothly when passing through the device, avoiding the fabric from getting stuck and tangled, and improving the efficiency of fabric correction and feeding. The offset transmission groups 2 located at both ends of the mounting base 4 are staggered, so that the transmission mechanism 201 and the transmission gap on the same axis are arranged alternately. Therefore, unlike the traditional structure in which the power point of moving the fabric is set in a straight line, the offset distribution of the offset transmission groups 2 allows for a more comprehensive and detailed offset operation on the fabric, ensuring that the fabric can be effectively offset in the entire width direction, improving the accuracy of offset. Moreover, due to the existence of the transmission gap, the fabric has room to move after being moved and forming folds, thus preventing the fabric from excessively piling up in a certain position. As a result, the folds of the sewn fabric are evenly distributed, making the appearance of the sewn fabric better.

[0041] The transmission mechanism 201 includes a correction belt 2014. The rotation of the central shaft 101 ultimately drives the correction belt 2014 to rotate. A portion of the correction belt 2014 is exposed outside the mounting base 4. When the correction belt 2014 rotates, it applies a lateral correction force to the fabric. The rotation plane of the correction belt 2014 is orthogonal to the rotation axis of the central drive structure 1. This design allows the correction belt 2014 to apply a lateral correction force perpendicular to the feed direction to the fabric while it is being fed. The correction belt 2014 is made of rubber, which has good elasticity and friction, allowing for better contact with the fabric and effectively applying a lateral correction force, thus improving the correction effect. Simultaneously, the rubber material also has a certain degree of wear resistance, extending the service life of the correction belt 2014.

[0042] The mounting base 4 has a accommodating arc groove 401 in the middle. The accommodating arc groove 401 is used to accommodate the fabric that is wrinkled due to being moved, which avoids the accumulation and damage of the fabric due to wrinkles during the correction process, and ensures the flatness and integrity of the fabric, so that the fabric can be smoothly processed in subsequent operations.

[0043] In the specific structure of the transmission mechanism 201, the central shaft 101 is connected to the central worm gear 104. The transmission mechanism 201 includes an internal gear 2017, which meshes with the central worm gear 104. The side of the internal gear 2017 away from the central worm gear 104 meshes with an external gear 2013. This gear-meshing transmission method can accurately transmit power, ensuring the stability and reliability of the rotation of the correction belt 2014. At the same time, gear transmission has high transmission efficiency, effectively transmitting the power of the central shaft 101 to the correction belt 2014.

[0044] The central shaft 101 is connected to several second bearings 103, and the outer ring of the second bearings 103 is connected to the rotating seat 5 and the end cover 3.

[0045] A correction belt 2014 is fitted onto the external gear 2013. The correction belt 2014 is a round belt. The external gear 2013 has at least one inlaid arc groove 20131, and the correction belt 2014 is fitted into the inlaid arc groove 20131. The design of the inlaid arc groove 20131 ensures that the correction belt 2014 is firmly fitted onto the external gear 2013, preventing slippage during rotation and ensuring the accuracy and stability of power transmission. The transmission mechanism 201 also includes an inner rotating shaft 2015, which is connected to the inner gear 2017 via a fourth bearing 2016; the external gear 2013 is connected to the outer rotating shaft 2011 via a third bearing 2013.

[0046] The bearing arrangement reduces the frictional resistance when the inner shaft 2015 and the outer shaft 2011 rotate, improves the flexibility and stability of rotation, and ensures the normal operation of the transmission mechanism 201.

[0047] Both sides of the mounting base 4 are provided with several inner shaft grooves 402. The inner shaft grooves 402 are connected end to end to form a polygonal groove, in which the inner rotating shaft 2015 is fitted. An inner gear groove 403 is vertically provided at the center of the inner shaft groove 402, which is used to accommodate the inner gear 2017. An outer shaft groove 404 is provided near the receiving arc groove 401 of the mounting base 4. The outer rotating shaft 2011 is fitted into the outer shaft groove 404. A third belt groove 405 is provided perpendicular to the outer shaft groove 404, in which a part of the correction belt 2014 is fitted. The arrangement of these grooves provides accurate installation positions for each component, ensures the fitting accuracy between components, and makes the structure of the entire device more compact and stable.

[0048] The mounting base 4 is connected to the end cap 3 on the side away from the rotating base 5. The rotating base 5 has a second groove 501, and the end cap 3 has a first groove 301. The first groove 301 and the third groove 405 on one side of the mounting base 4 are directly opposite each other to form a first correction mounting cavity. A portion of the correction actuating band 2014 is fitted into the first correction mounting cavity, and the other portion is exposed outside the rotating base 5 and the mounting base 4. The second groove 501 and the third groove 405 on the other side of the mounting base 4 are directly opposite each other to form a second correction mounting cavity. A portion of the correction actuating band 2014 is fitted into the second correction mounting cavity, and the other portion is exposed outside the rotating base 5 and the mounting base 4. The first and second correction mounting cavities provide a stable mounting space for the correction actuating band 2014, ensuring the stability and reliability of the correction actuating band 2014 during rotation.

[0049] During the operation of the device, the rotation of the central drive structure 1 generates fabric feeding power, driving the correction belt 2014 to move laterally perpendicular to the feeding direction, applying a lateral correction force to the fabric through its exposed portion. The vector synthesis of the feeding motion and the correction motion achieves the directional conveying and automatic correction functions of the fabric. This design, which combines feeding and correction functions, allows the fabric to complete both feeding and correction operations simultaneously as it passes through the device, improving the working efficiency of the garment manufacturing equipment and the quality of fabric processing.

[0050] This utility model's fabric correction and feeding device, by setting a accommodating arc groove 401 in the middle of the mounting base 4, avoids the accumulation and damage of fabric caused by wrinkles during the correction process, ensuring the uniformity of wrinkle distribution formed during sewing. This allows the fabric to proceed smoothly to subsequent processing operations, guaranteeing the normal operation of the garment manufacturing equipment and the quality of fabric processing. The staggered distribution of the correction transmission group 2 allows the transmission mechanism 201 and the transmission gap on the same axis to be arranged alternately, thereby achieving a more comprehensive and detailed correction operation on the fabric. This overcomes the limitation of traditional structures that set the power point for moving the fabric in a straight line, ensuring effective correction of the fabric throughout its width. Furthermore, the existence of the transmission gap provides space for the fabric to move after being moved and forming wrinkles, preventing excessive accumulation of fabric at a certain position. The fabric can move and adjust more freely within the transmission gap, avoiding the impact of local accumulation on fabric conveying and processing quality. Therefore, it enables a uniform distribution of wrinkles during sewing, resulting in a better appearance of the sewn garment and improving product quality and market competitiveness.

[0051] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
