Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, and in particular to a cloth detection device for shirt production. Background Art

[0002] Fabric quality testing is a crucial step in the shirt production process, primarily involving appearance quality testing, dimensional stability testing, and tensile and tear strength testing. For tensile and tear strength testing, a fabric sample is secured in a fixture and a gradually increasing force is applied in a straight line until the fabric breaks. A tensile tester then measures the force at break. To obtain accurate test results, the warp or weft direction of the fabric must be aligned with the direction of the tension. This allows for separate evaluation of the fabric's tensile properties in both the warp and weft directions, providing a comprehensive understanding of the fabric's mechanical properties.

[0003] When using existing tensile testing devices to test fabrics, testers need to use a fabric direction meter to determine the warp and weft directions of the fabric, mark them, and then fix the fabric on a fixture based on the marks. This operation process is overly dependent on external auxiliary devices and is cumbersome, resulting in low fabric testing efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings mentioned in the above background, the present invention provides a cloth detection device for shirt production.

[0005] The technical solution of the present invention is: a fabric detection device for shirt production, comprising: a detection platform, a drive module is installed on the detection platform, and a tension detector is installed at the power output end of the drive module; two fixed seats, respectively fixed to the tension detector and the detection platform, two symmetrical first driving members are installed on the fixed seat, and the telescopic ends of the first driving members are fixed to the first clamping member; two symmetrical second driving members are both fixed to the fixed seat near the tension detector, and the telescopic ends of the second driving members are fixed to the second clamping member.

[0006] Advantageously, the central axis of the second clamping member is perpendicular to the horizontal plane.

[0007] Advantageously, the opposite sides of the two first clamping members on the same fixing seat are both provided with wavy surfaces.

[0008] Advantageously, it further comprises: a clamping and winding mechanism, having two, respectively provided on the two fixing seats, for winding and fixing the cloth, the clamping and winding mechanism comprising: an elastic telescopic rod, fixed to the adjacent fixing seats; a fixing frame, fixed to the telescopic end of the elastic telescopic rod, the fixing frame being rotatably connected to a support bar; a third clamping member, having two, both slidably connected to the support bar; a driving assembly, provided on the fixing frame, for driving the corresponding two third clamping members to move toward each other, thereby clamping the cloth.

[0009] Advantageously, the third clamping member is a semi-cylinder, and the opposite sides of the two third clamping members on the same fixing seat are vertical planes.

[0010] Advantageously, the two first clamping members on the same fixing seat are both provided with an arcuate surface on one side close to the corresponding third clamping member, and the radius of the circle where the arcuate surface is located is greater than the radius of the circle where the third clamping member is located.

[0011] Advantageously, a midpoint of a line connecting two of the first clamping members, a midpoint of a line connecting two of the second clamping members, and a midpoint of a line connecting two of the third clamping members on the same fixing seat are all located on the same vertical plane.

[0012] Advantageously, the drive assembly includes: a third drive member, fixed to the fixed frame, the telescopic end of the third drive member being fixed to the first plate; a second plate, rotatably connected to the side of the first plate away from the third drive member; two pulling rods, both hinged to the side of the second plate away from the first plate, the pulling rods being hinged to the corresponding third clamping members.

[0013] Advantageously, a driving motor is mounted on the fixing frame, and a gear set is used to transmit power between the output shaft of the driving motor and the first plate.

[0014] Advantageously, an elastic member is fixed between the first plate and the second plate.

[0015] The effect achieved by the present invention is as follows: the present invention folds the fabric to be tested in half and forms the fabric into a "cylindrical" shape, then inserts the "cylindrical" fabric into one of the second clamping members, and makes the "cylindrical" fabric fit the outer side of the second clamping member, so that the fabric is perpendicular to the horizontal plane, thereby ensuring that the warp or weft of the fabric is consistent with the direction of the tension, ensuring the accuracy of the tensile test on the fabric, and at the same time, does not require auxiliary equipment, thereby improving the detection efficiency, simplifying the operation steps, and reducing the risk of unexpected situations.

[0016] The present invention clamps the cloth by two third clamping members on the same fixed seat, and cloth is left on the upper and lower parts of the two third clamping members. The upper and lower parts of the cloth are then rolled up by the rotation of the two third clamping members, so that the upper and lower parts of the cloth are in contact with and squeezed with each other. The cloth is fixed by relying on the friction and squeezing force between the cloths, and the probability of relative sliding between the cloth and the third clamping members is reduced, thereby ensuring the stability of the first clamping member in clamping the cloth, and ensuring the accuracy of the cloth detection result.

[0017] The present invention compresses the cloth by means of two third clamping members and the adjacent first clamping members, thereby further reducing the probability of relative sliding between the cloth and the first clamping members.

[0018] The present invention applies a rotational force to the third clamping member through the stored force state of the elastic member, thereby causing the third clamping member to have a tendency to continue to reel in the fabric, while ensuring a close fit of the fabric thereon, improving the stability of the fabric, and ensuring the accuracy of the detected data.

DETAILED DESCRIPTION

[0029] The above scheme is further described below with reference to specific embodiments. It should be understood that these embodiments are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the embodiments can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments. In this application, the first drive member, the second drive member, and the third drive member mentioned are all telescopic push rods, which can be hydraulically driven, electrically driven, or gas-driven, and can be adjusted according to the use environment.

[0030] Example 1: A fabric detection device for shirt production, referring to Figures 1-4 and Figure 8 , including: a testing platform 1, a driving module 2 is installed on the testing platform 1, and a tension detector 3 is installed at the power output end of the driving module 2; a fixing seat 4, which has two, which are respectively fixed to the tension detector 3 and the testing platform 1, and two symmetrical first driving members 5 are installed on the fixing seat 4, and the telescopic end of the first driving member 5 is fixed to the first clamping member 6; the opposite sides of the two first clamping members 6 on the same fixing seat 4 are both provided with a wave surface; a second driving member 7, which has two symmetrical ones, both fixed to the fixing seat 4 close to the tension detector 3, and the telescopic end of the second driving member 7 is fixed to the second clamping member 8; the central axis of the second clamping member 8 is perpendicular to the horizontal plane.

[0031] In the above scheme, a control terminal is installed on one side of the detection table 1, and a display is provided on the control terminal. The control terminal is electrically connected to all the following electrical components. The driving module 2 is an existing structure, which is used to drive the upper fixing seat 4 to move, thereby completing the stretching of the fabric; the tension detector 3 is used to detect the tension applied to the fabric, and its tension value is displayed on the display of the control terminal; the wavy surface on the first clamping member 6 is used to increase its contact area with the fabric and reduce the probability of the fabric slipping when stretched; the second clamping member 8 is in a vertical state to ensure that the subsequently clamped fabric is also in a vertical state. The second clamping member 8 is a cylinder.

[0032] Workflow: When it is necessary to use this device to test the tensile strength of the fabric, the operator first folds the fabric to be tested in half (taking folding it in half along its warp direction as an example) to align the edges of the fabric. The folded fabric will form a "cylindrical" shape. The operator then inserts the "cylindrical" fabric into one of the second clamping members 8 so that the upper side of the fabric fits against the fixing seat 4 (at this time the fabric is located between the corresponding two first clamping members 6). Subsequently, the operator pulls the fabric forward, and the back side of the "cylindrical" fabric fits against the outer side of the second clamping member 8. At this time, since the second clamping member 8 is in a vertical state and the fabric is in a folded state, that is, the weft of the fabric and the axis of the second clamping member 8 are perpendicular to each other, and the warp of the fabric and the axis of the second clamping member 8 are parallel, so that the warp of the fabric corresponds to the direction of the pulling force.

[0033] After the cloth is fitted with the outer side of the second clamping member 8, the control terminal turns on the two second driving members 7, and the telescopic ends of the two second driving members 7 respectively drive the adjacent second clamping members 8 to move in opposite directions and clamp the "cylindrical" cloth. Then the operator releases the cloth and the two second driving members 7 stop working. At this time, the cloth is opened and located in the middle between the corresponding two first clamping members 6, and the cloth is perpendicular to the horizontal plane, that is, the warp of the cloth corresponds to the direction of the tension. Then the control terminal turns on all the first driving members 5, and all the first driving members 5 respectively drive the adjacent first clamping members 6 to move until the corresponding two first clamping members 6 clamp the cloth together. Then all the first driving members 5 stop working, and the cloth is fixed at this time (such as Figure 8 shown).

[0034] After the cloth is clamped, the control terminal controls the two second driving members 7 to reset their telescopic ends and drive the adjacent second clamping members 8 to reset, thereby breaking contact between the second clamping members 8 and the cloth.

[0035] After the two second clamping members 8 are reset, the control terminal turns on the driving module 2. The power output end of the driving module 2 drives the upper fixing seat 4 to move upward through the tension detector 3, thereby stretching the fabric (along its warp direction). The tension detector 3 transmits the data to the control terminal until the fabric breaks, and the operator records the data.

[0036] After the test is completed, the control terminal controls the drive module 2 to drive the tension detector 3 and the upper fixing base 4 to reset. The above operation is then repeated to test the remaining fabrics. At the same time, the operator can fold the fabric in half according to the weft, so that the weft is aligned with the direction of tension, thus realizing the stretch detection of the fabric weft.

[0037] Example 2: Based on Example 1, Figure 2 、 Figure 3 and Figure 5-Figure 9, also includes: a clamping and winding mechanism, which has two, respectively arranged on two fixed seats 4, for winding and fixing the cloth, and the clamping and winding mechanism includes: an elastic telescopic rod 21, fixed to the adjacent fixed seat 4; a fixing frame 22, fixed to the telescopic end of the elastic telescopic rod 21, and the fixing frame 22 is rotatably connected to the support bar 23; a third clamping member 24, which has two, both of which are slidably connected to the support bar 23; a driving component is provided on the fixing frame 22, for driving the corresponding two third clamping members 24 to move toward each other, thereby winding the cloth Clamping; the third clamping piece 24 is a semi-cylinder, and the opposite sides of the two third clamping pieces 24 on the same fixed seat 4 are vertical planes; the two first clamping pieces 6 on the same fixed seat 4 are provided with an arcuate surface on one side close to the corresponding third clamping piece 24, and the radius of the circle where the arcuate surface is located is greater than the radius of the circle where the third clamping piece 24 is located; the midpoint of the line between the two first clamping pieces 6 on the same fixed seat 4, the midpoint of the line between the two second clamping pieces 8 and the midpoint of the line between the two third clamping pieces 24 are all located on the same vertical plane.

[0038] In the above scheme, the elastic telescopic rod 21 is equipped with a tension spring, and the fixing frame 22 is composed of a connecting plate, a square frame and a circular frame. The circular frame is used for rotating the support bar 23; the arc surface on the first clamping member 6 is used to position the adjacent third clamping member 24 to ensure the stability of the third clamping member 24; the support bar 23 is provided with two symmetrically distributed slide grooves, and the third clamping member 24 slides in the adjacent slide grooves; the vertical plane of the third clamping member 24 is used to ensure that it is in full contact with the fabric; by limiting the positions of the two first clamping members 6, the two second clamping members 8 and the two third clamping members 24, the flatness of the fabric stretching is ensured, while the force direction of the fabric is ensured; Figure 8 and Figure 9 The figure only shows the status of the fabric.

[0039] refer to Figure 3 and Figure 5-Figure 7The driving assembly includes: a third driving member 31, which is fixed to the fixing frame 22, and the telescopic end of the third driving member 31 is initially in an extended state. The telescopic end of the third driving member 31 is fixed to the first plate 32; the second plate 33 is rotatably connected to the front side of the first plate 32; a pulling rod 34 has two, both of which are hinged to the front side of the second plate 33, and the pulling rod 34 is hinged to the corresponding third clamping member 24. The pulling rod 34 makes the corresponding two third clamping members 24 move relative to each other, so that the two third clamping members 24 complete the clamping and fixing of the fabric; the fixing frame 22 is installed with The drive motor 51, the output shaft of the drive motor 51 and the first plate 32 are transmitted through a gear set, and the output shaft of the drive motor 51 and the first plate 32 are fixedly connected with spur gears, and the spur gears of the two are meshed with each other. The length of the spur gear on the output shaft of the drive motor 51 is greater than the distance moved by the first plate 32, ensuring that the spur gear on the first plate 32 and the spur gear on the output shaft of the drive motor 51 are always in a meshing state; an elastic member 41 is fixedly connected between the first plate 32 and the second plate 33, and the elastic member 41 is a torsion spring, which is used to transmit the rotation of the first plate 32 to the second plate 33.

[0040] Workflow: After all the first clamping members 6 clamp the fabric, the control terminal turns on the two third driving members 31. The following content is described according to the third driving member 31 on the upper side and the parts thereon. The telescopic end of the third driving member 31 is retracted and drives the first plate 32 to move backward. The first plate 32 drives the two pull rods 34 thereon to move through the adjacent second plate 33. The two pull rods 34 respectively drive the adjacent third clamping members 24 to move. The two third clamping members 24 slide along the support bar 23 until the two third clamping members 24 contact and clamp the fabric. The control terminal then turns off the third driving member 31. At this time, the state of the fabric is as follows: Figure 8 shown.

[0041] After the two third clamping members 24 clamp the fabric, the control terminal controls the two second driving members 7 to reset their telescopic ends and drive the adjacent second clamping members 8 to reset. Then the control terminal turns on the drive motor 51, and the output shaft of the drive motor 51 drives the first plate 32 to rotate counterclockwise through the gear set ( Figure 1 The first plate 32 drives the second plate 33 to rotate through the elastic member 41, and the second plate 33 drives the two third clamping members 24 to rotate through the two pull rods 34. The two third clamping members 24 jointly drive the support bar 23 to rotate counterclockwise along the circular frame of the fixing frame 22.

[0042] During the rotation of the two third clamping members 24, when the two third clamping members 24 rotate to 90°, the two third clamping members 24 drive the cloth located on the upper side thereof to swing to the left (the part of the cloth close to the second clamping member 8, referred to as section A below), and drive the cloth located on the lower side thereof to swing to the right (the part of the cloth close to the first clamping member 6, referred to as section B below), and the third clamping member 24 located on the left side gradually contacts section B.

[0043] During the rotation of the two third clamping members 24, the two third clamping members 24 pull section B. Since section B is clamped by the two first clamping members 6, section B applies a downward pulling force to the two third clamping members 24. The two third clamping members 24 move downward. The third clamping members 24 drive the fixing frame 22 to move downward through the support bar 23. The fixing frame 22 drives the telescopic end of the elastic telescopic rod 21 to move downward, and the tension spring on the elastic telescopic rod 21 stores force.

[0044] After the two third clamping members 24 rotate to 180°, the two third clamping members 24 drive section A to rotate to the lower side and make section A contact with section B. At this time, the third clamping member 24 on the left side is in contact with section B, and the two third clamping members 24 continue to move downward, and the telescopic end of the elastic telescopic rod 21 continues to extend.

[0045] After the two third clamping members 24 rotate to 180 degrees, the two third clamping members 24 continue to rotate, and the third clamping member 24 on the right gradually contacts section A, and section B gradually wraps section A. When the two third clamping members 24 rotate to 360 degrees, the states of the two third clamping members 24 and their upper and lower parts are as follows: Figure 9 As shown, as the two third clamping members 24 continue to rotate, section B completely wraps section A. At the same time, since section B applies a downward force to the two third clamping members 24, section B squeezes section A, and the squeezing force gradually increases as the downward movement distance of the third clamping members 24 increases. In this way, the upper and lower parts of the fabric are squeezed against each other by the two third clamping members 24, and the friction between the fabrics is used to fix the fabric, thereby reducing the probability of relative movement between the fabric and the third clamping members 24.

[0046] As the two third clamping members 24 rotate and move downward, the two third clamping members 24 continue to wrap around section B. When the two third clamping members 24 are blocked by the adjacent first clamping members 6 and cannot move further, the two third clamping members 24 will rotate slightly and tighten the fabric thereon until the two third clamping members 24 cannot rotate anymore. The fabric wrapped around the two third clamping members 24 is in close contact with the curved surface on the first clamping member 6. At the same time, the first clamping member 6 and the adjacent third clamping members 24 squeeze the fabric between them to ensure that the fabric is fixed.

[0047] When the two third clamping members 24 cannot rotate, the two pulling rods 34 and the second plate 33 cannot rotate, and the output shaft of the drive motor 51 continues to drive the first plate 32 to rotate, causing the elastic member 41 to twist and accumulate force. Then the control terminal turns off the drive motor 51, thereby stopping the rotation of the first plate 32. At this time, under the action of the elastic member 41, the second plate 33 always tends to rotate counterclockwise, so that the two third clamping members 24 always have the force to reel in the fabric, thereby ensuring the fixing force on the fabric.

[0048] After turning off the drive motor 51, the control terminal starts to perform stretching detection on the fabric according to the operating steps of Example 1. During the fabric detection process, the friction between the fabrics wrapped around the two third clamping members 24 and the squeezing force of the third clamping members 24 and the adjacent first clamping members 6 on the fabric are used to improve the fixing effect of the fabric and reduce the probability of relative sliding between the fabric and the third clamping members 24 and the first clamping members 6, thereby ensuring the accuracy of the detection data.

[0049] After the fabric inspection is completed, the control terminal turns on the drive motor 51, causing its output shaft to rotate in the opposite direction, and the two third clamping members 24 to rotate in the opposite direction, thereby releasing the fabric wrapped thereon. During this process, the telescopic end of the elastic telescopic rod 21 moves upward under the action of the tension spring thereon, and the telescopic end of the elastic telescopic rod 21 drives the two third clamping members 24 to move upward and reset through the fixing frame 22 and the support bar 23, until the telescopic end of the elastic telescopic rod 21 is reset, and the two third clamping members 24 return to their initial height. Then the control terminal turns off the drive motor 51 and turns on the telescopic end of the third driving member 31 to extend and drive the two third clamping members 24 to move backward, so that the two third clamping members 24 are reset. After all parts are reset, the operator removes the fabric that has been inspected and repeats all the above processes to continue stretching the subsequent fabrics.

[0050] The above description is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the scope of protection of the present invention.
