Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable tape processing and production technology, and in particular to a heat shrinkable tape production winding device. Background Technology

[0002] In the modern electrical engineering industry, heat shrinkable tape plays a crucial role due to its unique properties. In the laying and maintenance of power cables, heat shrinkable tape is commonly used at cable joints and terminals. During operation, joints and terminals of power cables are susceptible to environmental factors such as moisture and oxidation. Heat shrinkable tape tightly wraps these areas, forming a reliable insulating and sealing protective layer, effectively preventing moisture intrusion and avoiding faults such as leakage and short circuits caused by decreased insulation performance, thus ensuring the stability and safety of power transmission. During the production process of heat shrinkable tape, slitting requires the use of a winding device for winding.

[0003] Existing heat shrinkable tape production winding devices cannot effectively control the tension of the heat shrinkable tape during the winding process, resulting in wrinkles and deformation of the product during winding. For example, utility model patent CN221796404U discloses a heat shrinkable tape winding mechanism, including a frame, a traction device on one side of the frame, a receiving groove on the top of the frame, multiple heating rods at the bottom of the receiving groove, multiple guide rollers between the two side walls of the receiving groove, a winding seat on the side of the frame away from the traction device, a winding motor mounted on the winding seat, a winding roller connected to the output shaft of the winding motor, and a winding sleeve fitted onto the winding roller. Anti-rotation elements are provided on the winding roller and at both ends of the winding sleeve, and anti-rotation grooves are respectively provided on the inner walls of both ends of the winding sleeve for the anti-rotation elements to pass through.

[0004] While the aforementioned utility model patent allows for quick removal of the heat shrinkable tape from the take-up roller by using a sleeve fitted onto the take-up roller, enabling direct removal of the sleeve with the heat shrinkable tape during unloading, it lacks a device for monitoring and adjusting the tension of the heat shrinkable tape. During actual winding, as the diameter of the heat shrinkable tape on the take-up roller increases, its tension gradually changes, and the current device cannot effectively control this change. Excessive tension can easily lead to overstretching, deformation, or even breakage of the heat shrinkable tape; conversely, insufficient tension can result in loose winding and wrinkles, all of which negatively impact the product quality.

[0005] Therefore, it is necessary to develop a heat shrinkable tape production and winding device to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a heat shrinkable tape production winding device that can dynamically adjust the tension of the heat shrinkable tape by controlling the change in the roll diameter during the winding process, thereby improving product quality.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a heat shrinkable tape production and winding device, comprising a base frame, characterized in that: a winding drum is rotatably connected to one end of the base frame, and a first motor for driving the winding drum to rotate is fixedly connected to the base frame; a limit component is provided at the other end of the base frame, the limit component being used to limit the two ends of the heat shrinkable tape; a tension adjustment component is provided between the winding drum and the limit component; a controller is fixedly connected to the outer wall of the base frame, and the first motor, the limit component, and the tension adjustment component are all electrically connected to the controller.

[0009] Furthermore, the limiting component includes a mounting plate, which is fixedly connected to the top surface of the base frame. Two sliding plates are slidably connected to both ends of the top surface of the mounting plate. A limiting plate is fixedly connected to the top surface of the two sliding plates. A driving component is provided on the mounting plate, which is used to drive the two sliding plates to move closer to each other and further away from each other at the same time.

[0010] Furthermore, the driving component includes a second motor and a bidirectional lead screw. The bottom surface of the mounting plate has a first sliding groove along its length. The bidirectional lead screw is rotatably connected to the inner wall of the first sliding groove. Slider blocks are threaded onto both the positive and negative thread sections of the bidirectional lead screw. The two sliders are respectively fixedly connected to the two sliding plates. The second motor is electrically connected to the controller.

[0011] Furthermore, a first roller is rotatably connected to one side of the two limiting plates that are close to each other, and a second roller that cooperates with the first roller is rotatably connected above the first roller. The limiting plates are provided with an adjusting member for adjusting the distance between the first roller and the second roller.

[0012] Furthermore, the adjusting component includes an adjusting screw, a second sliding groove is vertically provided on the side wall of the limiting plate, a first mounting block is slidably connected in the second sliding groove, one end of the second roller is rotatably connected to the first mounting block, the adjusting screw is vertically arranged and its bottom end is rotatably connected to the top surface of the first mounting block, and the top end of the adjusting screw passes through the limiting plate and is threadedly connected to it.

[0013] Furthermore, the tension adjustment assembly includes two guide rollers rotatably connected to the base frame; a gantry frame is disposed between the two guide rollers and fixedly connected to the base frame; a U-shaped mounting seat is slidably connected to the inner wall of the gantry frame; a telescopic member is fixedly connected to the top of the gantry frame, and the telescopic end of the telescopic member is fixedly connected to the gantry frame; mounting grooves are formed on the inner walls of both ends of the U-shaped mounting seat; a pressure sensor is fixedly connected to the bottom surface of the mounting groove; a second mounting block is disposed in the mounting groove, and the second mounting block is in contact with the pressure sensor; a tension adjustment roller is rotatably connected between the two second mounting blocks; the telescopic member, the pressure sensor, and the controller are electrically connected.

[0014] Furthermore, two flattening rollers are rotatably connected to the end of the base frame away from the winding drum.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This invention incorporates a tension adjustment component and a controller. Both the first motor and the tension adjustment component are electrically connected to the controller. The controller can control the tension adjustment component, dynamically adjusting the tension of the heat shrinkable tape based on changes in the tape's diameter during winding. This maintains a constant tension throughout the winding process, preventing excessive stretching, deformation, or even breakage due to excessive tension, and also preventing loose winding and wrinkles due to insufficient tension, thus ensuring the quality of the heat shrinkable tape.

[0017] Meanwhile, by setting the limiting components, the two ends of the shrink tape can be limited to prevent the heat shrink tape from deviating during the winding process, so that the heat shrink tape can be neatly wound on the winding drum, further improving the winding quality and product quality.

[0024] The core of this utility model is to provide a heat shrinkable tape production winding device that can dynamically adjust the tension of the heat shrinkable tape by controlling the change in the roll diameter during the winding process, thereby improving product quality.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In one specific embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the device includes a base frame 1, with a take-up drum 2 rotatably connected to one end of the base frame 1. A first motor 3 for driving the take-up drum 2 to rotate is fixedly connected to the base frame 1. A limit assembly 4 is provided at the other end of the base frame 1 to limit the two ends of the heat shrinkable tape 5. A tension adjustment assembly 6 is provided between the take-up drum 2 and the limit assembly. A controller 7 is fixedly connected to the outer wall of the base frame 1. The first motor 3, the limit assembly 4, and the tension adjustment assembly 6 are all electrically connected to the controller 7.

[0028] In one specific embodiment of this utility model, such as Figure 1 and Figure 2As shown, the limiting component 4 includes a mounting plate 401, which is fixedly connected to the top surface of the base frame 1. Two sliding plates 402 are slidably connected to both ends of the top surface of the mounting plate 401. A limiting plate 403 is fixedly connected to the top surface of the two sliding plates 402. A driving component is provided on the mounting plate 401, which is used to drive the two sliding plates 402 to move closer to each other and further away from each other at the same time.

[0029] By setting the slide plate 402 and the limiting plate 403, the edges on both sides of the heat shrinkable tape 5 can be limited. The driving component can flexibly adjust the distance between the two limiting plates 403 according to the width of the heat shrinkable tape 5 to adapt to heat shrinkable tapes 5 of different specifications and improve the versatility of the device.

[0030] Specifically, the driving components include a second motor 404 and a bidirectional lead screw 405. A first groove 406 is provided on the bottom surface of the mounting plate 401 along its length. The bidirectional lead screw 405 is rotatably connected to the inner wall of the first groove 406. A slider 407 is threaded onto both the positive and negative thread sections of the bidirectional lead screw 405. The two sliders 407 are fixedly connected to two slide plates 402 respectively. The second motor 404 is electrically connected to the controller 7.

[0031] Driven by the motor 404, the bidirectional lead screw 405 is rotated. Due to the characteristics of the forward and reverse thread sections of the bidirectional lead screw 405, its rotation will cause the two sliders 407 to move closer to each other or further away from each other at the same time, thereby driving the two sliding plates 402 and the limiting plate 403 to move, so as to realize the automatic adjustment of the distance between the two limiting plates 403.

[0032] Specifically, a first roller 408 is rotatably connected to one side of the two limiting plates 403 that are close to each other, and a second roller 409 that cooperates with the first roller 408 is rotatably connected above the first roller 408. An adjusting component is provided on the limiting plate 403 for adjusting the distance between the first roller 408 and the second roller 409.

[0033] By using the first roller 408 and the second roller 409, the friction between the heat shrinkable tape 5 and the limiting plate 403 can be reduced, preventing damage to the surface of the heat shrinkable tape 5. The adjusting component can adjust the distance between the first roller 408 and the second roller 409 according to the thickness of the heat shrinkable tape 5, ensuring that it can provide good limiting and protection for heat shrinkable tapes 5 of different thicknesses.

[0034] Specifically, the adjusting component includes an adjusting screw 410, a second sliding groove 411 vertically opened on the side wall of the limiting plate 403, a first mounting block 412 slidably connected in the second sliding groove 411, a second roller 409 rotatably connected at one end to the first mounting block 412, the adjusting screw 410 being vertically set and its bottom end being rotatably connected to the top surface of the first mounting block 412, and the top end of the adjusting screw 410 penetrating through the limiting plate 403 and being threadedly connected to it.

[0035] By rotating the adjusting screw 410, which is threadedly connected to the limiting plate 403 and rotatably connected to the first mounting block 412 at its bottom end, and the first mounting block 412 sliding in the second slide groove 411, the rotation of the adjusting screw 410 can drive the first mounting block 412 to move up and down in the second slide groove 411, thereby adjusting the distance between the first roller 408 and the second roller 409, and achieving clamping and limiting of both ends of the heat shrinkable tape 55.

[0036] In one specific embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the tension adjustment assembly 6 includes two guide rollers 601, which are rotatably connected to the base frame 1. A gantry frame 602 is provided between the two guide rollers 601 and is fixedly connected to the base frame 1. A U-shaped mounting seat 603 is slidably connected to the inner wall of the gantry frame 602. A telescopic component 604 is fixedly connected to the top of the gantry frame 602, and the telescopic end of the telescopic component 604 is fixedly connected to the gantry frame 602. Mounting grooves 605 are provided on the inner walls of both ends of the U-shaped mounting seat 603. A pressure sensor 606 is fixedly connected to the bottom surface of the mounting groove 605. A second mounting block 607 is provided in the mounting groove 605 and is in contact with the pressure sensor 606. A tension adjustment roller 608 is rotatably connected between the two second mounting blocks 607. The telescopic component 604, the pressure sensor 606, and the controller 7 are electrically connected.

[0037] Specifically, the telescopic component 604 adopts one of the following: a hydraulic cylinder, an electric cylinder, or an electric push rod.

[0038] The heat shrinkable tape 5 is guided by guide roller 601. Gantry 602 provides mounting support for U-shaped mounting base 603 and telescopic component 604. Pressure sensor 606 monitors the pressure of the heat shrinkable tape 5 on tension adjusting roller 608 in real time, converting the pressure signal into an electrical signal and transmitting it to controller 7. Controller 7 determines the tension of the heat shrinkable tape 5 based on the pressure signal. When the tension is abnormal, it controls the telescopic component 604 to extend or retract, causing U-shaped mounting base 603 to move up and down, thereby adjusting the pressure of tension adjusting roller 608 on heat shrinkable tape 5, achieving dynamic adjustment of the tension of heat shrinkable tape 5, and ensuring winding quality. Specifically, pressure sensor 606 is a Honeywell 1750 diffused silicon pressure sensor. During installation, pressure sensor 606 is placed on the bottom surface of mounting grooves 605 on the inner walls of both ends of U-shaped mounting base 603, and the pressure sensor is firmly fixed in the mounting grooves 605 using screws or glue, with the sensing surface of pressure sensor 606 facing upwards. Place the second mounting block 607 into the mounting slot 605 so that it is in close contact with the sensing surface of the pressure sensor 606.

[0039] In one specific embodiment of this utility model, such as Figure 1 and Figure 3As shown, two flattening rollers 8 are rotatably connected to the end of the base frame 1 away from the winding drum 2. The distance between the two flattening rollers 8 is adjustable, which is existing technology and will not be described in detail here. Before the heat shrinkable tape 5 enters the winding process, the flattening rollers 8 flatten the heat shrinkable tape 5 to eliminate any wrinkles or unevenness that may exist in the heat shrinkable tape 5, so that the heat shrinkable tape 5 is wound in a flat state, further improving the winding quality.

[0040] The working principle of this utility model is as follows: When using the heat shrinkable tape production and winding device, one end of the heat shrinkable tape 5 is first passed through two parallel and rotatably connected flattening rollers 8 at the end of the base frame 1 away from the winding drum 2, so that the heat shrinkable tape 5 is tightly adhered to the outer circumferential surface of the two flattening rollers. Under the rotation of the flattening rollers, the upper and lower surfaces of the heat shrinkable tape 5 are subjected to pressure, and unevenness such as wrinkles and bends generated during the production process is eliminated, allowing it to continue moving forward in a flat state.

[0041] Next, the heat shrinkable tape 5 enters the limiting assembly 4, passing between the two limiting plates 403, and is positioned between the first roller 408 and the second roller 409 on the side of the limiting plates that are close to each other. Previously, the operator had driven the bidirectional lead screw 405 to rotate by the second motor 404 according to the width of the heat shrinkable tape 5, which in turn drove the slider 407 on the positive and negative threaded sections, thereby moving the slide plate 402 and the limiting plate 403 fixedly connected to the slider, and adjusting the appropriate distance between the two limiting plates 403. At the same time, according to the thickness of the heat shrinkable tape 5, the first mounting block 412, which is rotatably connected to the bottom end of the screw and slides in the second slide groove 411, is moved by rotating the adjusting screw 410, thereby adjusting the distance between the first roller 408 and the second roller 409, ensuring that the heat shrinkable tape 5 can pass smoothly and be clamped and limited.

[0042] Subsequently, the heat shrinkable tape 5 enters the tension adjustment assembly 6, first bypassing one of the guide rollers 601 rotatably connected to the base frame 1, then moving upwards around the tension adjustment roller 608 rotatably connected between the two second mounting blocks 607, and then downwards around the other guide roller 601. During this process, the pressure applied by the heat shrinkable tape 5 to the tension adjustment roller is transmitted through the second mounting blocks to pressure sensors 606 mounted on the bottom surface of the mounting grooves 605 on both ends of the U-shaped mounting base 603. The pressure sensors monitor the tension of the heat shrinkable tape 5 in real time and convert the pressure signal into an electrical signal, feeding it back to the controller 7. The controller 7 determines whether the tension of the heat shrinkable tape 5 is within a suitable range based on the received signal. If the tension is abnormal, it controls the telescopic component 604 to extend or retract, causing the U-shaped mounting base and the tension adjustment roller to move up and down, changing the degree of curvature of the heat shrinkable tape 5 as it bypasses the tension adjustment roller, thus achieving dynamic adjustment of the tension of the heat shrinkable tape 5.

Similar or identical parts between embodiments can be referred to interchangeably.
