Description

Technical Field

[0001] This application relates to the field of roll diameter measurement technology, and in particular to roll diameter fine-tuning fixtures. Background Technology

[0002] In unwinding and winding equipment, it is necessary to limit the maximum diameter of the material roll to prevent it from becoming too large and affecting other equipment. This is typically achieved by using sensors to monitor the roll diameter. When the roll diameter exceeds a threshold, an alarm sounds, stopping the unwinding and winding equipment. In actual production, a hollow, columnar support exists near the roll, containing multiple cables. The sensor is mounted on the outer surface of the support, emitting a signal from above towards the roll's axis. As the roll winds up, its diameter gradually increases. After the sensor emits a signal, it falls on the roll and reflects back to the sensor, thus monitoring the roll diameter.

[0003] In related technologies, to set an alarm threshold for the roll diameter, a connecting rod is typically used, resting against both the roll drum and the support. A scale is positioned on the connecting rod, and a sliding baffle is installed on the connecting rod or scale. The distance between the baffle and the support axis is read using the scale, allowing the baffle to slide to the maximum roll diameter. At this point, the baffle reflects the signal from the sensor, which is then used as the alarm threshold. However, because the scale measures the distance between the support axis and the roll drum axis, it cannot measure the distance from the sensor signal transmitter to the roll drum axis. This results in a discrepancy between the measured data and the required value, causing detection errors in subsequent winding and unwinding operations. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a roll diameter fine-tuning fixture that can accurately measure the distance between the sensor and the maximum roll diameter.

[0005] This application provides a roll diameter fine-tuning fixture, which includes a main body and a measuring mechanism. The main body includes a connecting rod, a hinge seat, a first positioning member, and a second positioning member. The hinge seat is connected to the connecting rod, and the two opposite ends of the connecting rod are respectively connected to the first positioning member and the second positioning member. The first positioning member is used to abut against the material cylinder, and the second positioning member is used to abut against the support. The measuring mechanism includes a rotating rod, a slider, and a baffle. The rotating rod is hinged to the hinge seat, and the plane of the rotation path of the rotating rod is parallel to the plane of the rotation path of the connecting rod. The slider is mounted on the rotating rod and slides along the length direction of the rotating rod. The baffle is fixed to the slider, and the surface of the baffle is perpendicular to the length direction of the rotating rod.

[0006] Furthermore, the hinge seat is slidably connected to the connecting rod, the hinge seat slides along the width direction of the connecting rod, and the connecting rod is provided with a first fixing member, which is used to fix the relative position of the hinge seat and the connecting rod.

[0007] Furthermore, the connecting rod has a hollow hole that extends along the width of the connecting rod, and the hinge seat has a fixing hole. The first fixing member passes through the hollow hole and is connected to the fixing hole, and the first fixing member slides along the extension direction of the hollow hole.

[0008] Furthermore, the measuring mechanism also includes a second fixing member, which is used to fix the relative position of the hinge seat and the rotating rod.

[0009] Furthermore, the baffle is located on the side of the slider closer to the first positioning member.

[0010] Furthermore, the measuring mechanism also includes a third fixing member, which is mounted on the slider and is used to fix the relative position of the slider and the rotating rod.

[0011] Furthermore, the third fixing member is a bolt, which is screwed to the slider, and passes through the slider and abuts against the rotating rod.

[0012] Furthermore, the first positioning member is slidably connected to the connecting rod, and the first positioning member slides along the length direction of the connecting rod.

[0013] Furthermore, the side of the first positioning member away from the second positioning member is an arc surface.

[0014] Furthermore, the side of the second positioning member that is away from the first positioning member is an arc surface.

[0015] The technical solution provided in this application may include the following beneficial results: by hinged to the hinge seat, the baffle can slide along the length direction of the rotating rod, so that the length direction of the rotating rod can be parallel to the detection direction of the sensor by rotating relative to the connecting rod. This makes it easier for the staff to measure the distance between the sensor and the baffle more accurately, so that an alarm can be triggered when the roll reaches the maximum roll diameter, avoiding detection errors in subsequent winding and unwinding operations.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] In related technologies, since the scale measures the distance between the support axis and the drum axis, it cannot measure the distance from the sensor signal transmitter to the drum axis. This leads to a discrepancy between the measured data and the required value, causing detection errors in subsequent winding and unwinding operations. To address the above problem, this application provides a roll diameter fine-tuning fixture that can accurately measure the distance between the sensor and the maximum roll diameter.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 and Figure 2 The roll diameter fine-tuning fixture includes a main body 1 and a measuring mechanism 2. The main body 1 includes a connecting rod 11, a hinge seat 12, a first positioning member 13, and a second positioning member 14. The hinge seat 12 is connected to the connecting rod 11, and the two opposite ends of the connecting rod 11 are respectively connected to the first positioning member 13 and the second positioning member 14. The first positioning member 13 is used to abut against the material cylinder 4, and the second positioning member 14 is used to abut against the support 6. In actual use, by abutting the first positioning member 13 against the material cylinder 4 and the second positioning member 14 against the support 6, the connecting rod 11 is fixed relative to the material cylinder 4 and the support 6, thereby positioning the position of the connecting rod 11.

[0027] See Figure 1 and Figure 2The measuring mechanism 2 includes a rotating rod 21, a slider 22, and a baffle 23. The rotating rod 21 is hinged to a hinge seat 12 and can rotate relative to the hinge seat 12 and relative to the connecting rod 11. The plane containing the rotation path of the rotating rod 21 is parallel to the plane containing the rotation path of the connecting rod 11. The slider 22 is mounted on the rotating rod 21 and slides along the length of the rotating rod 21. The baffle 23 is fixed to the slider 22. When the slider 22 slides along the length of the rotating rod 21, the baffle 23 moves accordingly along the length of the rotating rod 21, thereby adjusting the position of the baffle 23 relative to the rotating rod 21. The surface of the baffle 23 is perpendicular to the length of the rotating rod 21, ensuring that the surface of the baffle 23 can abut against the coil 3 on the material cylinder 4.

[0028] In the actual production process of the electrode sheet, the support 6 is located on one side of the material roll 3, and a sensor 5 is installed on the support 6. The sensor 5 can be a roll diameter measuring sensor. The sensor 5 can detect the roll diameter of the material roll 3, and the diameter of the material cylinder 4 can be measured in advance. When the sensor 5 detects that the roll diameter of the material roll 3 reaches a threshold, the alarm will sound. The sensor 5 needs to be calibrated before use to ensure that the alarm sounds when the sensor 5 detects a certain value, that is, when the distance between the sensor 5 and the material roll 3 reaches a certain value. When installing the roll diameter fine-tuning fixture, first place the first positioning part 13 against the material cylinder 4, and place the second positioning part 14 against the support 6. Then, rotate the rotating rod 21 relative to the connecting rod 11 so that the length direction of the rotating rod 21 is parallel to the detection direction of the sensor 5. Next, slide the slider 22 so that the baffle 23 reaches the maximum roll diameter of the material roll 3, which is the position where an alarm should be triggered when the material roll 3 exceeds this diameter. At this time, the detection direction of the sensor 5 is directly facing the surface of the baffle 23. The baffle 23 can reflect the laser or infrared light irradiated by the sensor 5. Set the value read by the sensor 5 at this position as the threshold for the alarm. It is best to remove the roll diameter fine-tuning fixture from the support 6 and the material cylinder 4. During the winding process of the material roll 3, the sensor 5 collects the roll diameter data of the material roll 3 in real time. When the material roll 3 reaches the maximum roll diameter, the alarm receives the data collected by the sensor 5 and analyzes that the material roll 3 has reached the maximum roll diameter, and the alarm sounds.

[0029] This application hinges the rotating rod 21 to the hinge seat 12, allowing the baffle 23 to slide along the length of the rotating rod 21. This enables the rotating rod 21 to rotate relative to the connecting rod 11, making its length parallel to the detection direction of the sensor 5. This allows workers to more accurately measure the distance between the sensor 5 and the baffle 23, thus triggering an alarm when the roll 3 reaches its maximum diameter, preventing detection errors in subsequent winding and unwinding operations.

[0030] See Figure 1-3The hinge seat 12 is slidably connected to the connecting rod 11. The hinge seat 12 slides along the width direction of the connecting rod 11. When the length direction of the rotating rod 21 is parallel to the detection direction of the sensor 5, the operator can slide the hinge seat 12 along the width direction of the connecting rod 11 to make the detection direction of the sensor 5 face the baffle 23, ensuring that the sensor 5 can collect the infrared or laser light reflected back by the baffle 23. The connecting rod 11 is provided with a first fixing member 112, which is used to fix the relative position of the hinge seat 12 and the connecting rod 11, preventing the hinge seat 12 from shaking relative to the connecting rod 11 when adjusting the sensor 5, and facilitating the operator to adjust the sensor 5.

[0031] See Figure 1 and Figure 4 The connecting rod 11 has a hollow hole 111 extending along the width direction of the connecting rod 11. In some embodiments, the hinge seat 12 has a fixing hole, and the first fixing member 112 passes through the hollow hole 111 and is connected to the fixing hole. The first fixing member 112 can slide along the extension direction of the hollow hole 111. The fixing hole has an internal thread, and the first fixing member 112 is a bolt. The first fixing member 112 is screwed to the fixing hole. When it is necessary to fix the relative position of the hinge seat 12 and the connecting rod 11, the friction between the hinge seat 12 and the connecting rod 11 can be increased by tightening the first fixing member 112, thereby fixing the hinge seat 12 and the connecting rod 11 relative to each other. In some embodiments, the hinge seat 12 has a metal rod passing through the hollow hole 111. The metal rod can slide along the extension direction of the hollow hole 111. The first fixing member 112 is a snap-fit ​​member. The first fixing member 112 is fastened to the hinge seat 12, thereby fixing the connecting rod 11 and the hinge seat 12 relative to each other.

[0032] See Figure 1 and Figure 2The measuring mechanism 2 also includes a second fixing member 24, which is used to fix the relative position of the hinge seat 12 and the rotating rod 21. When the rotating rod 21 rotates relative to the connecting rod 11 to a suitable angle, so that the detection direction of the sensor 5 is parallel to the length direction of the connecting rod 11, the relative position of the hinge seat 12 and the rotating rod 21 can be fixed by the second fixing member 24, so that the hinge seat 12 and the rotating rod 21 are relatively fixed, preventing the sensor 5 from deflecting during the debugging process and avoiding affecting the debugging of the sensor 5. In some embodiments, the second fixing member 24 is a bolt and a nut. The second fixing member 24 passes through the hinge seat 12 and the rotating rod 21, and the hinge seat 12 and the rotating rod 21 are sandwiched between the second fixing member 24. When it is necessary to fix the relative position of the hinge seat 12 and the rotating rod 21, the operator can tighten the second fixing member 24 to increase the friction between the hinge seat 12 and the rotating rod 21, thereby fixing the hinge seat 12 and the rotating rod 21 relatively. In some embodiments, the second fixing member 24 may be a fastener, which fastens the rotating rod 21 and the hinge seat 12 relative to each other by fastening the second fixing member 24 to the hinge seat 12.

[0033] See Figure 1-3 In some embodiments, the baffle 23 is located on the side of the slider 22 near the first positioning member 13. Since the material roll 3 has a large volume, in order to ensure that the baffle 23 can be attached to the material roll, the baffle 23 is set on the side of the slider 22 near the first positioning member 13 to avoid the slider 22 obstructing the baffle 23 from being attached to the material roll 3, so that the staff can more accurately measure the distance between the sensor 5 and the baffle 23.

[0034] See Figure 1-3 In some embodiments, the rotating rod 21 is a ruler. When setting the maximum diameter of the material roll 3, in addition to using the sensor 5 to measure the distance between the sensor 5 and the baffle 23, the operator can also read the distance value between the sensor 5 and the baffle 23 using the ruler, thereby manually setting the alarm threshold. In some embodiments, the operator can use an external measuring ruler to measure the distance between the baffle 23 and the detection port of the sensor 5.

[0035] See Figure 1 and Figure 2The measuring mechanism 2 also includes a third fixing member 25, which is installed on the slider 22. The third fixing member 25 is used to fix the relative position of the slider 22 and the rotating rod 21. When the operator moves the baffle 23 to the maximum roll diameter of the material roll 3, the relative position of the slider 22 and the rotating rod 21 can be fixed by the third fixing member, so as to prevent the slider 22 from sliding again due to gravity and affecting the debugging of the sensor 5. Specifically, the third fixing member 25 is a bolt, which is screwed to the slider 22. The third fixing member 25 passes through the slider 22 and abuts against the rotating rod 21. When the operator needs to fix the relative position of the slider 22 and the rotating rod 21, the third fixing member 25 can be tightened to increase the pressure of the third fixing member 25 on the rotating rod 21, so that the slider 22 is stuck on the rotating rod 21. When the operator needs to slide the slider 22, the third fixing member 25 can be loosened to make the third fixing member 25 leave the rotating rod 21. At this time, the operator can slide the slider 22 along the length of the rotating rod 21.

[0036] See Figure 1-3 In some embodiments, the first positioning member 13 is slidably connected to the connecting rod 11. The first positioning member 13 slides along the length of the connecting rod 11. Specifically, one end of the connecting rod 11 extends into the first positioning member 13. The surface of the first positioning member 13 is provided with at least one fixing screw, which passes through the first positioning member 13 and abuts against the surface of the connecting rod 11. When it is necessary to adjust the relative position of the first positioning member 13 and the connecting rod 11, the fixing screw can be loosened, and then the length of the connecting rod 11 extending into the first positioning member 13 can be adjusted, thereby changing the relative position of the first positioning member 13 and the connecting rod 11. When it is necessary to fix the relative position of the first positioning member 13 and the connecting rod 11, the operator can tighten the fixing screw, so that the fixing screw abuts against the surface of the connecting rod 11 and increases the pressure of the fixing screw on the connecting rod 11, so that the first positioning member 13 is stuck on the connecting rod 11, thereby fixing the first positioning member 13 and the connecting rod 11 relatively. When the operator needs to position the connecting rod 11 relative to the material cylinder 4 and the support 6, the first positioning part 13 can be slid relative to the connecting rod 11 to increase the length of the part of the connecting rod 11 inserted into the first positioning part 13, thereby reducing the maximum length of the entire roll diameter fine adjustment fixture. Then, the second positioning part 14 is placed against the support 6. Next, the first positioning part 13 is aligned with the material cylinder 4, and then the first positioning part 13 is slid relative to the connecting rod 11 to extend the maximum length of the entire roll diameter fine adjustment fixture until the first positioning part 13 abuts against the material cylinder 4, thus completing the positioning of the connecting rod 11 by the material cylinder 4 and the support 6.

[0037] See Figure 1 and Figure 2The side of the first positioning member 13 away from the second positioning member 14 is an arc surface. Preferably, the side of the first positioning member 13 away from the second positioning member 14 matches the side shape of the material cylinder 4, so that the first positioning member 13 can fit better with the material cylinder 4, which facilitates the positioning of the relative position of the connecting rod 11 and the material cylinder 4.

[0038] See Figure 1 and Figure 2 The side of the second positioning member 14 away from the first positioning member 13 is an arc surface. Preferably, the side of the second positioning member 14 away from the first positioning member 13 matches the side shape of the support 6, so that the second positioning member 14 can fit better with the support 6, which facilitates the positioning of the relative position of the connecting rod 11 and the support 6.
