[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0026] As attached Figure 1 To be continued Figure 10 As shown, this invention discloses a tension control device 1 capable of automatically calibrating tension, comprising a base plate 101 and a vertical plate 102 perpendicularly disposed to the base plate 101. The vertical plate 102 is provided with a drive roller 20 and a first drive source 30 connected to the drive roller 20, the first drive source 30 being used to drive the drive roller 20 to rotate for conveying the crown belt 100; and a tension roller 40 and a tension control element 50 (such as a hysteresis device). The tension roller 40 and the tension control element 50 are disposed downstream of the drive roller 20 (with reference to the flow direction of the crown belt 100). The tension control element 50 is disposed on the vertical plate 102 and connected to the tension roller 40, and the tension control element 50 is used to control the winding of the belt onto the tension roller. The system includes: tension of the crown band 100 on the drive roller 20; a floating roller assembly 60 disposed between the drive roller 20 and the tension roller 40 and movable up and down on the vertical plate 102, the floating roller assembly 60 being used to adjust the speed difference between the drive roller 20 and the tension roller 40; a plurality of transition rollers 70 for tensioning the crown band 100; and a tension detection device 80 and a tension calibration device 90, the tension detection device 80 and the tension calibration device 90 being disposed downstream of the tension roller 40 (with reference to the flow direction of the crown band 100), the tension detection device 80 being used to detect the tension of the crown band 100 in real time, and the tension calibration device 90 being used to calibrate the tension detection device 80.

[0027] Furthermore, the tension calibration device 90 of the present invention includes a crown band separation device, a calibration element 902, and a calibration element moving device. The crown band separation device is used to separate the crown band 100 from the support roller 801 during tension calibration, so that the crown band 100 does not contact the support roller 801. The calibration element moving device is used to fix and move the calibration element 902 onto the tension detector 802 (such as a tension sensor) during tension calibration, and to remove the calibration element 902 from the tension detector 802 when crown band tension is detected, so that the calibration element 902 no longer contacts the tension detector 802.

[0028] With the above configuration, tension control and detection of the crown band 100 can be achieved. When needed, the tension detection device 80 is automatically calibrated by the tension calibration device 90 to ensure the reliable operation of the tension detection device 80. When tension calibration is performed, the crown band separation device first separates the crown band 100 from the support roller 801, so that the crown band 100 is no longer in contact with the support roller 801. That is, during tension calibration, the tension detector 802 will not be affected by the tension of the crown band 100. The calibration component moving device moves the calibration component 902 and places it on the tension detector 802, and calibrates the tension detector 802 through the calibration component 902. When tension detection is performed, the crown band separation device returns to its original position, the crown band 100 is conveyed on the support roller 801, the calibration component moving device fixes the calibration component 902 and removes the calibration component 902 from the tension detector 802, so that the calibration component 902 is no longer in contact with the tension detector 802. The tension detector 802 detects the tension on the crown band 100 in real time through the support roller 801.

[0029] The tension detection device 80 of this invention includes a support roller 801 fixedly mounted on a vertical plate 102 and a tension detector 802. The tension detector 802 is mounted on a base plate 101 and connected to the support roller 801 via a first connector 803. When the crown belt 100 is being conveyed, it travels on the support roller 801, and the tension detector 802 detects the tension on the crown belt 100 in real time via the support roller 801. The tension detected by the tension detector 802 is compared with a tension value set by the system. When the detected tension value is outside the set tension value range, the hysteresis valve 50 is adjusted to change the tension magnitude, ultimately adjusting it to the desired predetermined tension value range.

[0030] The floating roller assembly 60 of this invention includes a rotatable floating roller 601, a fixed shaft 602, and a fixed base 603. The fixed shaft 602 is fixedly mounted on the fixed base 603. The floating roller 601 is rotatably connected to the fixed shaft 602. The fixed base 603 can move up and down on the vertical plate 102 via a linear slide rail 604, thereby driving the floating roller 601 to move up and down on the vertical plate 102. The floating roller assembly 60 is used to adjust the speed difference between the tension roller 40 and the drive roller 20. Specifically, when the speed of the tension roller 40 is greater than the speed of the drive roller 20, the floating roller 601 moves upward under the tension of the crown belt 100. When the speed of the tension roller 40 is less than the speed of the drive roller 20, the floating roller 601 moves downward under its own weight. When the speed of the tension roller 40 is close to the speed of the drive roller 20, the floating roller 601 hardly moves. The vertical movement of the floating roller 601 is detected in real time by a ranging element 605 mounted on the vertical plate 102, and the detection result is sent to the control system (not shown). The control system adjusts the rotational speed of the first drive source 30 based on the position of the floating roller 601 detected by the ranging element 605, thereby adjusting the speed of the drive roller 20, and ultimately adjusting the speed difference between the drive roller 20 and the tension roller 40, i.e., speed matching. The ranging element 605 can be a laser rangefinder or a linear displacement sensor, etc.

[0031] Furthermore, the tension roller 40 of the present invention is also connected to an encoder 501, which can be connected to the tension roller 40 via a shaft connection or a synchronous belt and synchronous pulley. The encoder 501 is used to detect the rotational speed of the tension roller 40 and feed the rotational speed of the tension roller 40 back to the control system, thereby controlling the first drive source 30 to adjust the rotational speed of the drive roller 20. Through the encoder 501, the floating roller assembly 60, and the ranging element 605, the speed difference between the drive roller 20 and the tension roller 40 is adjusted, thereby matching the speeds of the drive roller 20 and the tension roller 40.

[0032] Specifically, the crown band separation device of the present invention includes a lifting rod 9011, a second drive source 9012, and a second connecting member 9013. The second drive source 9012 is fixedly disposed on the side of the upright plate 102 away from the crown band 100. The drive end of the second drive source 9012 is fixedly connected to the second connecting member 9013. The lifting rod 9011 is fixedly disposed on the second connecting member 9013 and moves synchronously with the second connecting member 9013. The lifting rod 9011 is disposed on the same side as the crown band 100 and is disposed below the crown band 100 in the area of ​​the support roller 801. The second drive source 9012 can drive the lifting rod 9011 to move upward to lift and raise the crown band 100, thereby separating it from the support roller 801. When the crown belt 100 is being conveyed, the lifting rod 9011 is positioned below the crown belt 100 and does not interfere with the conveying of the crown belt 100 on the support roller 801. When tension calibration is being performed, the second drive source 9012 drives the lifting rod 9011 to move upward and lift the crown belt 100, thereby separating the crown belt 100 from the support roller 801 and performing the tension calibration operation.

[0033] In addition, the calibration component moving device of the present invention includes a third driving source 9031 and a support component 9032 connected to the third driving source 9031. The third driving source 9031 is fixedly disposed on the side of the upright plate 102 away from the crown belt 100. The support component 9032 is disposed through a first slot (not shown) on the upright plate 102 and can move up and down at the first slot. A through hole (not shown) is provided in the middle of the calibration component 902. The size of the through hole is larger than the size of the support component 9032, so that the support component 9032 can pass through the calibration component 902 without contacting the calibration component 902. When performing a tension test on the crown strap 100, the third drive source 9031 drives the support member 9032 upwards and, after contacting the calibration member 902, lifts the calibration member 902, thus separating it from the tension detector 802. When calibrating the tension detector 802, the third drive source 9031 drives the support member 9032 downwards, placing the calibration member 902 on the tension detector 802. The third drive source 9031 continues to drive the support member 9032 downwards, preventing it from contacting the calibration member 902, ensuring that the weight of the support member 9032 is not applied to the tension detector 802 during calibration. During calibration, the known weight of the calibration member 902, in conjunction with the control system, allows the control system to calibrate the tension detector 802 when it is placed on the tension detector 802. The tension detector 802 can be automatically calibrated within a specified time by the control system, or calibrated when the tension detected by the tension detector 802 is not within the required tension range. The calibration element 902 has a known weight; preferably, the calibration element 902 is a weight.

[0034] As a second embodiment of the present invention, the main differences compared to the first embodiment lie in the crown band separation device and the calibration piece moving device; all other structures are the same, and the following description focuses only on the differences. Besides the aforementioned method of actively lifting the crown band to separate it from the support roller, the crown band can also be separated from the support roller by driving the support roller away from the crown band. Specifically, as shown in the attached... Figures 6 to 8As shown, the crown band separation device of the present invention includes a lifting rod 9011, a fourth drive source 9015, and a connecting shaft 9014. The fourth drive source 9015 is fixedly disposed on the side of the upright plate 102 away from the crown band 100. The lifting rod 9011 is disposed on the same side as the crown band 100 and fixedly disposed on the upright plate 102, and the lifting rod 9011 is disposed below the crown band 100 in the area of ​​the support roller 801. The driving end of the fourth drive source 9015 is fixedly connected to the tension detector 802 through the connecting shaft 9014. The fourth drive source 9015 is used to drive the tension detector 802 to move, thereby driving the support roller 801 to move, thereby driving the support roller 801 to contact or separate from the crown band 100. When the support roller 801 separates from the crown band 100, the lifting rod 9011 supports the crown band 100.

[0035] The calibration component moving device of the present invention includes a third driving source 9031 and a support component 9032 connected to the third driving source 9031. The third driving source 9031 is fixedly mounted on the tension detector 802. The driving end of the third driving source 9031 is fixedly connected to the support component 9032. A second slot (not shown) is provided on the first connecting component 803. A through hole is provided in the middle of the calibration component 902. The size of the through hole is larger than the size of the support component 9032, so that the support component 9032 passes through the second slot and penetrates the calibration component 902 without contacting the calibration component 902. The third driving source 9031 is used to drive the support component 9032 to lift or lower the calibration component 902. When the crown strap 100 is tested for conveying tension, the third drive source 9031 drives the support member 9032 to move upward and contact the calibration member 902, thus supporting the calibration member 902 and keeping it away from the tension detector 802, i.e., not in contact with the tension detector 802. When the tension detector 802 is calibrated, the third drive source 9031 drives the support member 9032 to move downward and place the calibration member 902 on the tension detector 802. The third drive source 9031 continues to drive the support member 9032 downward so that the support member 9032 does not contact the calibration member 902, so that the weight of the support member 9032 will not be loaded on the tension detector 802 during the calibration.

[0036] It should be noted that, in addition to lifting the crown band by means of a lever, the lever 9011 can also be replaced by a gripper mechanism to grasp the crown band. The gripper, driven by a drive source, grips and removes the crown band 100, ensuring that the crown band 100 does not contact the support roller 801 during tension detector 802 calibration. The support member 9032 can also be replaced by a gripper mechanism. The gripper mechanism, driven by a drive source, moves the calibration member 902. During tension detector 802 calibration, the calibration member 902 is placed on the tension detector 802; when not calibrating the tension detector 802, the calibration member 902 does not contact the tension detector 802.

[0037] As attached Figure 9 As shown, the present invention also discloses a crown band extrusion coating production line 1000, which includes a spindle frame 1001 for providing steel wire or nylon wire; an extruder device 1002 disposed downstream of the spindle frame 1001 for extruding rubber onto the steel wire or nylon to form a crown band 100; a traction cooling device 1003 disposed downstream of the extruder device 1002 for traction and cooling of the crown band 100; and a first storage device 1004 disposed downstream of the traction cooling device 1003 for traction and cooling of the crown band 100. 0 is temporarily stored; the crown band winding device 1005 (for specific structure and principle, please refer to the technical content disclosed in the applicant's invention patent No. 2021109657273) is used to wind the crown band 100 onto the H-beam or winding shaft to form a crown band roll; it also includes the tension control device 1 that can automatically calibrate the tension as described in this invention, the tension control device 1 is disposed between the storage device 1004 and the crown band winding device 1005, and is used to control the tension of the crown band 100 when the crown band is wound onto the H-beam or winding shaft.

[0038] Furthermore, the tension control device described in this invention can also be used in a crown belt winding production line to wind the crown belt onto the belt drum.

[0039] Therefore, as attached Figure 10 As shown, the present invention also discloses a crown band winding production line 2000, which includes: a crown band guiding device 2001 for guiding the crown band roll; a second storage device 2002 disposed downstream of the crown band guiding device 2001 for temporarily storing the guided crown band 100; a winding head 2003 (for the specific structure and principle, please refer to the technical content disclosed in the applicant's invention patent application No. 2019104661720) for pulling and winding the crown band 100 onto the belt drum; and a tension control device 1 disposed between the winding head 2003 and the second storage device 2002 for controlling the tension of the crown band 100 when winding it onto the belt drum.

[0040] In summary, the technical solution disclosed in this invention provides a tension control device capable of automatically calibrating tension. During the calibration of the tension detector 802, the crown belt 100 is separated from the support roller 801 by the crown belt separation device in the tension calibration device 90. The calibration component 902 is moved by the calibration component moving device, thereby achieving an automatically calibrated tension control device. This tension control device has advantages such as simple structure, ease of use, and suitability for integration with other automated equipment to form an automated production line.
