Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a detection device for cable insulation wrapping tape. Background Technology

[0002] As a key material for ensuring the safe and stable operation of power transmission systems, cable insulation wrapping tape's insulation performance, mechanical strength, and environmental adaptability directly determine the cable's protective effect. Among various testing items, adhesion testing assesses the tightness of the wrapping tape's adhesion to the cable conductor, avoiding risks such as detachment and insulation failure after construction due to insufficient adhesion. Adhesion testing devices typically consist of an electronic tensile testing machine, a standard bonding roller, a test rod, and sample cutting tools.

[0003] A search revealed that CN218974135U discloses a tape peel force testing device, comprising: a base; a test substrate for bonding tape and connected to the base; and a tape clamp for peeling the tape from the test substrate, including a first jaw and a second jaw for clamping and fixing the peeling end of the tape, which are vertically coordinated with the base and positioned above the test substrate; a drive assembly for driving the tape clamp to move up and down is provided between the base and the tape clamp. The above-mentioned tape peel force testing device has a reasonable structure and can test the peel resistance of tape after it is bonded to an item.

[0004] Current testing equipment still relies on manual operation in the tape-to-test rod bonding process. This involves a tester holding a standard bonding roller and rolling and pressing the tape along the length of the test rod to achieve bonding. However, the force applied manually by the bonding roller is uncontrollable, causing the pressure on the tape to deviate from the standard requirements, resulting in inconsistent actual contact areas between the tape and the substrate. Utility Model Content

[0005] The purpose of this invention is to provide a testing device for cable insulation wrapping tape, addressing the problem that existing testing devices still rely on manual operation in the tape-test rod bonding process. This involves a tester holding a standard bonding roller and rolling and pressing the wrapping tape along the length of the test rod to achieve bonding. However, the force applied manually by the bonding roller is uncontrollable, causing the pressure on the wrapping tape to deviate from the standard requirements, resulting in inconsistent actual contact areas between the tape and the substrate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A detection device for cable insulation wrapping tape includes a detection base and further includes: A drive unit, mounted on a detection unit, is configured to reciprocate along the vertical direction of the detection unit; Two rotating arms, one end of which is rotatably mounted on the drive base, are arranged symmetrically. Two pressing seats are located below the drive seat, and the end of the rotating arm away from the drive seat is rotatably connected to the pressing seats; The detection rod is mounted on the detection base, and two pressing seats are set on the detection rod. These seats are used to move along the axis of the detection rod as the rotating arm swings, pressing the cable insulation wrapping tape to adhere it to the detection rod.

[0007] In one embodiment, the bottom of the drive seat is provided with a mounting groove, and a connecting seat is installed in the mounting groove. The connecting seat is installed in the mounting groove, and one end of the two rotating arms is rotatably connected to the connecting seat.

[0008] In one embodiment, the bottom of the connecting seat is provided with a groove, and one end of each of the two rotating arms is rotatably connected to the groove.

[0009] Preferably, a gear is installed at one end of each of the two rotating arms, and a control plate is installed on the inner wall of the mounting groove. One end of the control plate passes through the connecting seat and extends into the groove. Racks are installed on both sides of the control plate, and the two gears mesh with the two racks respectively.

[0010] In one embodiment, an elastic element is installed between the connector and the inner wall of the mounting groove.

[0011] In one embodiment, a connector is mounted on the pressing seat, and the end of the rotating arm away from the connector is rotatably connected to the connector.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A detection device for cable insulation wrapping tape includes a detection base 100 and further includes: A drive seat 200 is mounted on a detection seat 100 and is configured to reciprocate along the vertical direction of the detection seat 100. Two rotating arms 301 are rotatably mounted on the drive base 200 at one end, and the two rotating arms 301 are arranged symmetrically. Two pressing seats 302 are located below the drive seat 200, and the end of the rotating arm 301 away from the drive seat 200 is rotatably connected to the pressing seats 302; The detection rod 400 is mounted on the detection base 100. Two pressing seats 302 are set on the detection rod 400 and are used to move along the axial direction of the detection rod 400 as the rotating arm 301 swings, pressing the cable insulation wrapping tape to adhere to the detection rod 400.

[0025] In the above technical solution, the vertical reciprocating movement of the drive seat 200 drives the two symmetrically arranged rotating arms 301 to swing, causing the two pressing seats 302 to move synchronously towards or away from each other along the axis of the detection rod 400. This can form a stable pressing on cable insulation wrapping tapes of different widths, ensuring that the wrapping tapes are tightly attached to the detection rod 400 and avoiding detection errors caused by loose attachment. At the same time, the symmetrical structure design ensures that the wrapping tapes are evenly stressed on both sides, preventing deformation of the wrapping tapes caused by excessive local compression, improving the stability and reliability of the detection process. Furthermore, the pressing seats 302 can adapt to wrapping tapes of different thicknesses within a certain range.

[0026] The bottom of the drive base 200 is provided with a mounting groove, and a connecting base 300 is installed in the mounting groove. The connecting base 300 is installed in the mounting groove, and one end of the two rotating arms 301 is rotatably connected to the connecting base 300.

[0027] The bottom of the connecting seat 300 has a groove, and one end of each of the two rotating arms 301 is rotatably connected to the groove. A gear 304 is installed at one end of each of the two rotating arms 301. A control plate 201 is installed on the inner wall of the mounting groove. One end of the control plate 201 passes through the connecting seat 300 and extends into the groove. Racks are installed on both sides of the control plate 201, and the two gears 304 mesh with the two racks respectively. An elastic element 202 is installed between the connecting seat 300 and the inner wall of the mounting groove.

[0028] Specifically, the elastic element 202 is a spring, or it can be a spring block. By setting an mounting groove and a connecting seat 300 at the bottom of the drive seat 200, a stable mounting reference is provided for the rotating arm 301. The groove at the bottom of the connecting seat 300 can limit the rotation range of the rotating arm 301. When the drive seat 200 initially moves downward, the connecting seat 300 drives the rotating arm 301 and the pressing seat 302 to move downward synchronously until the pressing seat 302 contacts the detection rod 400 and stops moving due to the obstruction of the detection rod 400. At this time, the rotating arm 301 and the connecting seat 300 remain relatively stationary because they are connected to the pressing seat 302. When the drive seat 200 continues to move downward, the control plate 201 in its mounting groove moves downward synchronously with the drive seat 200, while the connecting seat 300 is restricted by the rotating arm 301 and cannot continue to move downward, causing the control plate 201 to move downward relative to the connecting seat 300. The displacement occurs when the racks on both sides of the control plate 201 mesh with the gears 304 at the ends of the rotating arms 301. The racks drive the gears 304 to rotate, which in turn drives the two rotating arms 301 to swing outward around the connection point with the connecting seat 300, thus achieving active opening. During this process, the elastic element 202 between the connecting seat 300 and the inner wall of the mounting groove is compressed. Through deformation, it absorbs the kinetic energy of the continuous downward movement of the drive seat 200, providing a buffer for the relative movement between the control plate 201 and the connecting seat 300, and ensuring that the gears 304 and the racks always maintain reliable meshing. This allows the continuous downward movement of the drive seat 200 to be stably converted into the continuous unfolding of the rotating arms 301, making the pressing pressure of the pressing seat 302 on the cable insulation wrapping tape more uniform. When the drive seat 200 resets, the elastic element 202 between the connecting seat 300 and the mounting groove assists the connecting seat 300 in returning to its initial position.

[0029] A connector 303 is installed on the pressing base 302, and the end of the rotating arm 301 away from the connector 300 is rotatably connected to the connector 303.

[0030] Specifically, the connector 303 is fixedly installed on the pressing seat 302, forming a transition connection structure between the rotating arm 301 and the pressing seat 302. The end of the rotating arm 301 away from the connecting seat 300 is rotatably connected to the connector 303 through a pin or bearing, so that the swing of the rotating arm 301 can transmit force and movement to the pressing seat 302 with the connector 303 as the fulcrum. When the rotating arm 301 swings outward or inward under the drive of the gear 304 rack, the connector 303 converts the rotational motion of the rotating arm 301 into the linear motion of the pressing seat 302 along the detection rod 400. Due to the fixed relationship between the connector 303 and the pressing seat 302, the additional torque on the pressing seat 302 when the rotating arm 301 swings can be avoided, ensuring that the pressing seat 302 always moves smoothly along the axis of the detection rod 400.

[0031] The detection seat 100 has a moving groove 101, and the drive seat 200 is connected to the moving groove 101.

[0032] The detection seat 100 includes: a first power source 102, which is installed on the detection seat 100. A lead screw 103 is connected to the power shaft of the first power source 102. The end of the lead screw 103 away from the power shaft is threadedly connected to the drive seat 200.

[0033] In the above technical solution, the first power source 102 is a servo motor, or it can be a stepper motor. The moving groove 101 of the detection seat 100 serves as a guide structure. Its inner wall forms a sliding fit or clearance fit with the outer wall of the drive seat 200, limiting the motion freedom of the drive seat 200 so that it can only move along the extension direction of the moving groove 101. When the first power source 102 is working, its power shaft drives the lead screw 103 to rotate synchronously. Since the lead screw 103 is threadedly connected to the drive seat 200 and the drive seat 200 is constrained by the moving groove 101 and cannot rotate with the lead screw 103, the rotational motion of the lead screw 103 is converted into the linear motion of the drive seat 200 along the axis of the lead screw 103. By controlling the forward and reverse rotation of the first power source 102, the up and down movement of the drive seat 200 can be realized. By controlling the rotation angle of the power shaft, the movement distance of the drive seat 200 can be precisely controlled.

[0034] The testing base 100 also includes: two movable plates 502, which are respectively installed on both sides of the testing base 100; two clamping heads 503, which are respectively installed on the bottom ends of the two movable plates 502, and the two clamping heads 503 are used to clamp the cable insulation wrapping tape; two second power sources 500, which are respectively installed on both sides of the testing base 100; and two tension sensors 501, which are respectively installed on the power shafts of the two second power sources 500, and the detection end of the tension sensor 501 is connected to the corresponding movable plate 502.

[0035] In the above technical solution, the second power source 500 can be a linear motor or a cylinder. The second power sources 500 on both sides of the detection seat 100 serve as power output components for the clamping action. Their power shafts are fixedly connected to one end of the tension sensor 501, and the detection end of the tension sensor 501 is connected to the moving plate 502. The driving force of the second power source 500 can be transmitted to the moving plate 502 through the tension sensor 501. At the same time, the tension sensor 501 can collect the force value data in real time during the transmission process. The clamping head 503 clamps from both ends of the wrapping strip. The second power source 500 drives the moving plate 502 to move the clamping head 503 in a direction away from the detection rod 400. At this time, the tension sensor 501 can collect the tension value during the process of the wrapping strip being pulled. This value directly corresponds to the magnitude of the adhesion between the wrapping strip and the detection rod 400.

[0036] During use, the cable insulation wrapping tape to be tested is attached to the testing rod 400. The first power source 102 is started, and its power shaft drives the lead screw 103 to rotate clockwise. The rotational motion of the lead screw 103 is converted into the linear motion of the drive seat 200 downward along the moving groove 101. The drive seat 200 simultaneously drives the connecting seat 300, rotating arm 301, and pressing seat 302 in the bottom mounting groove to move downward as a whole. The pressing seat 302 first contacts the cable insulation wrapping tape on the surface of the testing rod 400. At this time, the pressing seat 302 is blocked by the testing rod 400 and cannot move further downward. The rotating arm 301 connected to the pressing seat 302 and the connecting seat 302... The seat 300 also stops moving downwards, while the drive seat 200 continues to move downwards under the drive of the first power source 102. The elastic element 202 between the connecting seat 300 and the inner wall of the mounting groove of the drive seat 200 begins to be compressed to provide subsequent transmission buffer. As the drive seat 200 continues to move downwards, the control plate 201 in the mounting groove moves downwards synchronously with the drive seat 200, while the connecting seat 300 remains stationary. This causes the control plate 201 to move downwards relative to the connecting seat 300. The racks on both sides of the control plate 201 mesh with the gears 304 at the ends of the rotating arms 301. The racks drive the gears 304 to rotate, causing the two rotating arms 301 to engage with the gears 304 at the ends of the rotating arms 301. The connection point of the connecting seat 300 swings outward axially. The swing of the rotating arm 301 is converted into synchronous opposite movement of the pressing seat 302 along the axis of the detection rod 400 through the connecting head 303 on the pressing seat 302. The pressing seat 302 applies uniform pressure to the wrapping tape, tightly adhering the wrapping tape to the surface of the detection rod 400. After the wrapping tape is adhered, the first power source 102 drives the drive seat 200 to return to its original position upward, and the pressing seat 302 disengages from the detection rod 400. The clamping head 503 firmly clamps both ends of the wrapping tape. The second power source 500 drives the moving plate 502 to move slowly away from the detection rod 400. The moving plate 502 pulls the clamping head 503, applying a tensile force along the axis of the detection rod 400 to the packaging tape, causing the packaging tape to tend to separate from the detection rod 400. During this process, the tension sensor 501 collects the tension value transmitted from the second power source 500 to the moving plate 502 in real time, and converts the collected force data into an electrical signal and transmits it to the external control system. The system records the tension change curve and peak tension as the core data for adhesion detection. When the packaging tape is completely peeled off from the surface of the detection rod 400, or when the tension value reaches the preset threshold, the second power source 500 stops working, and the adhesion detection stage ends.
