[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1 As shown, combined Figure 2 An embodiment of the present invention provides a fabric tension adjustment device 10 , including a first roller 110 , a second roller 120 and an adjustment mechanism 130 .

[0031] The first roller 110 and the second roller 120 are arranged opposite to each other and there is a material passing gap between them for the fabric 20 to pass through. The outer peripheral surface of the first roller 110 and / or the outer peripheral surface of the second roller 120 has a tooth comb structure. When the fabric 20 passes through the material passing gap between the first roller 110 and the second roller 120, the tooth comb structure of the outer peripheral surface of the first roller 110 and / or the outer peripheral surface of the second roller 120 will press the fabric 20, so that the fabric 20 has a certain tension, and further, the density of the weft structure or the warp structure of the fabric 20 becomes uniform.

[0032] It can be understood that the tooth comb structure in this embodiment can be that only the outer peripheral surface of the first roller 110 has the tooth comb structure, and the outer peripheral surface of the second roller 120 does not have the tooth comb structure; it can be that only the outer peripheral surface of the second roller 120 has the tooth comb structure, and the outer peripheral surface of the first roller 110 does not have the tooth comb structure; it can also be that both the outer peripheral surface of the first roller 110 and the outer peripheral surface of the second roller 120 have the tooth comb structure.

[0033] Preferably, the outer circumference of the first roller 110 and the outer circumference of the second roller 120 both have a tooth comb structure, and the comb teeth 140 on the tooth comb structure on the outer circumference of the first roller 110 and the comb teeth 140 on the tooth comb structure on the outer circumference of the second roller 120 are arranged at intervals to form a staggered fit. When the fabric 20 passes through the material passing interval between the first roller 110 and the second roller 120, both the front and back sides of the fabric 20 can be evenly pressed by the comb teeth 140, and the comb teeth 140 arranged at intervals can increase the force area of ​​the fabric 20 being pressed, which is more conducive to improving the density uniformity of the weft structure or the warp structure of the fabric 20.

[0034] The adjustment mechanism 130 is connected to the first roller 110 and / or the second roller 120, and is used to adjust the size of the material feeding gap. By adjusting the size of the material feeding gap between the first roller 110 and the second roller 120, the top pressure exerted on the fabric 20 when passing through the material feeding gap between the first roller 110 and the second roller 120 can be adjusted, thereby adjusting the tension of the fabric 20. Specifically, when the material feeding gap between the first roller 110 and the second roller 120 increases, when the fabric 20 passes through the material feeding gap between the first roller 110 and the second roller 120, the top pressure exerted by the tooth comb structure on the first roller 110 and / or the second roller 120 on the fabric 20 becomes smaller, thereby reducing the tension of the fabric 20. When the material transfer gap between the first roller 110 and the second roller 120 decreases and the fabric 20 passes through the material transfer gap between the first roller 110 and the second roller 120, the pressing force of the comb structure on the first roller 110 and / or the second roller 120 on the fabric 20 increases, thereby increasing the tension of the fabric 20.

[0035] It is understandable that the adjustment mechanism 130 may be connected only to the first roller 110, or only to the second roller 120, or both to the first roller 110 and the second roller 120. It is understandable that when the adjustment mechanism 130 is connected to both the first roller 110 and the second roller 120, the first roller 110 and the second roller 120 may be connected to different adjustment mechanisms 130, or the first roller 110 and the second roller 120 may be connected to the same adjustment mechanism 130.

[0036] In a specific example, the fabric tension adjustment device 10 further includes a machine platform, a first rotating shaft 150, a second rotating shaft 160 and a third rotating shaft 170, wherein the first rotating shaft 150 is connected to the machine platform, and one of the second rotating shaft 160 and the third rotating shaft 170 is connected to the machine platform, and the other rotating shaft is not connected to the machine platform, that is, in a suspended state. The adjustment mechanism 130 includes a connecting member 131, wherein the connecting member 131 is connected to the first rotating shaft 150, the first roller 110 is connected to the second rotating shaft 160, the second roller 120 is connected to the third rotating shaft 170, and the connecting member 131 is also connected to a rotating shaft not connected to the machine platform, and the connecting member 131 rotates around the first rotating shaft 150 to drive the roller connected to the rotating shaft not connected to the machine platform to rotate around the first rotating shaft 150.

[0037] It can be understood that the rollers rotate under the drive of the rotating shaft, thereby driving the fabric 20 to pass through the material passing gap between the first roller 110 and the second roller 120. By adopting a setting mode in which one of the second rotating shaft 160 and the third rotating shaft 170 is connected to the machine platform and the other rotating shaft is not connected to the machine platform, that is, in a suspended state, the position of one of the rollers can be fixed accordingly. When the other roller rotates around the first rotating shaft 150 due to the connecting member 131, the connecting member 131 will drive the rotating shaft not connected to the machine platform to rotate around the first rotating shaft 150. Further, due to the rotation of the rotating shaft not connected to the machine platform around the first rotating shaft 150, the position of the corresponding roller will be moved, further, the distance between the second rotating shaft 160 of the first roller 110 and the third rotating shaft 170 of the second roller 120 will be changed, further, the material passing gap between the first roller 110 and the second roller 120 will be changed, and further, the tension on the fabric 20 will be changed.

[0038] It can be understood that since the position of the corresponding roller needs to be moved by the rotation axis not connected to the machine platform rotating around the first rotation axis 150 , the rotation axis not connected to the machine platform does not coincide with the first rotation axis 150 .

[0039] It can be understood that since the roller corresponding to the rotating shaft not connected to the machine rotates around the first rotating shaft 150, this rotation is a circular motion, which can ensure that the corresponding roller moves within a limited distance, and can effectively avoid the device from losing control due to misoperation.

[0040] For example, the second rotating shaft 160 may be connected to the machine platform, and the third rotating shaft 170 may not be connected to the machine platform. Accordingly, the position of the first roller 110 is fixed, and the position of the second roller 120 moves under the drive of the connecting member 131. For another example, the third rotating shaft 170 may be connected to the machine platform, and the second rotating shaft 160 may not be connected to the machine platform. Accordingly, the position of the second roller 120 is fixed, and the position of the first roller 110 moves under the drive of the connecting member 131.

[0041] Furthermore, the connecting member 131 may be, for example, a connecting rod, or other connecting components, but is not limited thereto.

[0042] In a specific example, the adjustment mechanism 130 includes a driving assembly 132 , and the driving assembly 132 is connected to the connecting member 131 to drive the connecting member 131 to rotate. Further, the driving assembly 132 is used to drive the connecting member 131 to rotate around the first rotation axis 150 .

[0043] In a specific example, the fabric tension adjustment device 10 further includes a controller 180, and the drive assembly 132 includes a motor, the drive shaft of the motor is connected to the connecting member 131 for driving the connecting member 131 to rotate, and the motor is also electrically connected to the controller 180. It can be understood that when the drive shaft of the motor is braked, the connecting member 131 will be pulled to rotate around the first rotating shaft 150. The controller 180 may include, for example, a switch button. When the on button is pressed, the drive shaft of the motor starts to drive the connecting member 131 to rotate. When the off button is pressed, the drive shaft of the motor is turned off, and the connecting member 131 no longer rotates. The controller 180 may also include, for example, a command setting for the rotation direction and rotation amplitude of the connecting member 131. For example, when the material feeding interval is too large, resulting in too small tension, the controller 180 may set a command for the rotation direction and rotation amplitude of the connecting member 131, so that the connecting member 131 moves in a direction that can drive the first roller 110 or the second roller 120 to rotate so that the material feeding interval is reduced to increase the tension. More specifically, the controller 180 controls the connection member 131 to rotate about the first rotation axis 150 in a direction that can reduce the distance between the second rotation axis 160 of the first roller 110 and the third rotation axis 170 of the second roller 120 .

[0044] In a specific example, the adjustment mechanism 130 further includes a human-machine interactive input-output component 133, and the human-machine interactive input-output component 133 is electrically connected to the controller 180. It can be understood that the human-machine interactive input-output component 133 can realize remote control of the drive component 132, for example, the motor can be controlled to be turned on or off through the human-machine interactive input-output component 133. Further, the human-machine interactive input-output component 133 can be, for example, but not limited to, a display screen. Further, the display content of the display screen can, for example, include a button for controlling the start and stop of the drive component 132, for example, can also include a button for controlling the rotation direction and rotation amplitude of the connecting member 131, for example, can also include a display of the tension value data of the fabric 20, and so on, but is not limited to this.

[0045] In a specific example, the adjustment mechanism 130 further includes a monitoring component 134, which is connected to the connecting member 131, and the monitoring component 134 is used to monitor the rotation change value of the connecting member 131. It can be understood that by monitoring the rotation change value of the connecting member 131, the distance change value between the second rotating shaft 160 of the first roller 110 and the third rotating shaft 170 of the second roller 120 can be obtained, and further, the material passing interval between the first roller 110 and the second roller 120 can be obtained, and further, the tension of the fabric 20 can be obtained.

[0046] Furthermore, the monitoring component 134 includes a mechanical indicating part 1341, which includes an indicating scale 1341a and an indicating dial 1341b. The indicating scale 1341a is connected to the connecting member 131, and the indicating dial 1341b is used to indicate the position of the indicating scale 1341a. The position change value of the indicating scale 1341a corresponds to the rotation change value of the connecting member 131.

[0047] Further, the monitoring component 134 includes an electrical signal indicating part 1342, and the electrical signal indicating part 1342 includes a sliding resistor 1342a and a signal conversion part 1342b. One end of the sliding resistor 1342a is connected to the connecting member 131, and the other end is connected to the signal conversion part 1342b. The signal conversion part 1342b is used to calculate the rotation change value of the connecting member 131 according to the resistance change value of the sliding resistor 1342a. Specifically, the signal conversion part 1342b can be, for example, a programmable logic controller (PLC), and the signal of the sliding resistor 1342a can be calculated by the PLC. More specifically, when the connecting member 131 rotates around the first rotating shaft 150, the resistance value of the sliding resistor 1342a changes, and the PLC calculates according to the received resistance signal to obtain the rotation change value of the connecting member 131. Furthermore, the PLC can further calculate the material passing interval between the first roller 110 and the second roller 120. Furthermore, the PLC can further calculate the tension value of the fabric 20 .

[0048] It can be understood that the monitoring component 134 may include only the mechanical indicating part 1341, but not the electric signal indicating part 1342; the monitoring component 134 may include only the electric signal indicating part 1342, but not the mechanical indicating part 1341; the monitoring component 134 may also include both the mechanical indicating part 1341 and the electric signal indicating part 1342. Preferably, the monitoring component 134 includes both the mechanical indicating part 1341 and the electric signal indicating part 1342.

[0049] Furthermore, there may be multiple connecting members 131 , and the multiple connecting members 131 are fixedly connected to each other.

[0050] In a specific example, the monitoring component 134 includes a mechanical indication part 1341 and an electrical signal indication part 1342, and the connecting member 131 includes a first connecting member 1311 and a second connecting member 1312, and the first connecting member 1311 and the second connecting member 1312 are fixedly connected, one of the connecting members 131 is connected to the first rotating shaft 150, one end of the first connecting member 1311 is connected to the mechanical indication part 1341, and one end of the second connecting member 1312 is connected to the electrical signal indication part 1342, and the other end of the first connecting member 1311 or the other end of the second connecting member 1312 is also connected to a rotating shaft not connected to the machine.

[0051] It can be understood that the fixedly connected first connecting member 1311 and the second connecting member 1312 can be arranged at any angle, for example, the first connecting member 1311 and the second connecting member 1312 are arranged in a straight line, for example, the first connecting member 1311 and the second connecting member 1312 are arranged at an acute angle, for example, the first connecting member 1311 and the second connecting member 1312 are arranged at an obtuse angle, and so on.

[0052] It is understandable that the first connecting member 1311 may be connected to the first rotating shaft 150, or the second connecting member 1312 may be connected to the first rotating shaft 150. It is understandable that when the first rotating shaft 150 is disposed at the connection between the first connecting member 1311 and the second connecting member 1312, the first connecting member 1311 and the second connecting member 1312 may be connected to the first rotating shaft 150 at the same time.

[0053] It can be understood that when the other end of the first connecting member 1311 or the other end of the second connecting member 1312 is connected to a rotating shaft not connected to the machine, it is sufficient to ensure that the rotating shaft not connected to the machine does not overlap with the first rotating shaft 150. Whether the first rotating shaft 150 is connected to the first connecting member 1311 or the second connecting member 1312, it has no effect on the setting position of the rotating shaft not connected to the machine.

[0054] In a specific example, the human-machine interactive input-output component 133 is electrically connected to the signal converter 1342b. It can be understood that the human-machine interactive input-output component 133 is combined with the signal converter 1342b. After the signal converter 1342b calculates the rotation change value of the connecting member 131 according to the resistance value of the sliding resistor 1342a, the human-machine interactive input-output component 133 can automatically receive the data of the rotation change value of the connecting member 131, which is more conducive to intelligent operation. Specifically, for example, the human-machine interactive input-output component 133 is a display screen, and the rotation change value of the connecting member 131 can be displayed on the display screen. Further, the material passing interval between the first roller 110 and the second roller 120 can be displayed on the display screen. Further, the tension value of the fabric 20 can also be displayed on the display screen.

[0055] In a specific example, the connection member 131 includes a first connection member 1311 and a second connection member 1312 , and when the second connection member 1312 is connected to the electrical signal indicating unit 1342 , the human-computer interaction input and output component 133 receives data of the rotation change value of the second connection member 1312 .

[0056] It can be understood that the rotation change values ​​of the connecting member 131 reflected by the mechanical indicating portion 1341 and the electrical signal indicating portion 1342 are the same.

[0057] An embodiment of the present invention further provides a method for adjusting the tension of a fabric 20, wherein the fabric 20 is processed using the fabric tension adjusting device 10 in any of the above embodiments, and the method comprises the following steps:

[0058] The fabric 20 passes through the material transfer gap between the first roller 110 and the second roller 120 , and the tooth comb structure of the first roller 110 and / or the second roller 120 presses the fabric 20 to give the fabric 20 tension.

[0059] Furthermore, the tension of the fabric 20 is adjusted by adjusting the size of the material feeding interval through the adjusting mechanism 130 .

[0060] Furthermore, when the tension of the fabric 20 is too small, the material transfer interval between the first roller 110 and the second roller 120 is reduced by the adjusting mechanism 130 , and when the tension of the fabric 20 is too large, the material transfer interval between the first roller 110 and the second roller 120 is increased by the adjusting mechanism 130 .

[0061] It can be understood that the above-mentioned fabric tension adjustment device 10 can be used to adjust the weft tension or warp tension of the fabric 20, and further, it can be used to adjust the density uniformity of the weft structure or warp structure of the fabric 20, and further, it is beneficial to improve the gloss and color uniformity of the fabric 20 after mercerizing.

[0062] An embodiment of the present invention further provides a mercerizing device, comprising a fabric tension adjusting device 10 as described in any of the above examples.

[0063] The following are specific embodiments:

[0064] Embodiment 1:

The electrical signal indicator part 1342 includes a sliding resistor 1342a and a signal converter 1342b. The signal converter 1342b is a PLC. One end of the sliding resistor 1342a is connected to the other end of the second connecting member 1312. The other end of the sliding resistor 1342a is connected to the signal converter 1342b. The signal converter 1342b is used to calculate the rotation change value of the second connecting member 1312 according to the resistance change value of the sliding resistor 1342a.

[0074] The human-machine interactive input-output component 133 is electrically connected to the signal conversion component 1342 b.

[0075] According to the rotation change value of the first connecting member 1311 reflected by the position change value of the indicating scale 1341a in the mechanical indicating part 1341, or the rotation change value of the second connecting member 1312 calculated by the signal conversion component 1342b and displayed by the human-computer interaction input and output component 133, the size of the material transfer interval between the first roller 110 and the second roller 120 can be obtained, and further, the current tension value of the fabric 20 can be obtained, and data such as the material transfer interval and the tension value can be directly displayed on the display screen. If the tension is too low, the parameters for increasing the tension can be set through the human-machine interactive input and output component 133, such as setting the rotation direction and rotation amplitude of the first connecting member 1311 and the second connecting member 1312, and the driving component 132 receives the instruction of the human-machine interactive input and output component 133, and starts the driving shaft of the motor to drive the first connecting member 1311 to rotate around the first rotating shaft 150, and in a direction that can reduce the distance between the second rotating shaft 160 of the first roller 110 and the third rotating shaft 170 of the second roller 120, so that the material passing interval between the first roller 110 and the second roller 120 is reduced, the tension is increased, and the human-machine interactive input and output component 133 displays the latest tension value, and vice versa. The device can accurately control the tension of the fabric, with less manual intervention and high efficiency.
