Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for thin film processing, and in particular relates to a soft rope-shaped intelligent anti-tangling thin film static elimination device. Background Technology

[0002] Currently, in the film processing industry (such as plastic film slitting, printing, and winding processes), due to the material characteristics of the film and the friction and peeling during high-speed movement, the surface of the film is prone to accumulating static charge. The presence of static electricity not only causes the film to attract dust, lint and other impurities, affecting the appearance and quality of the product, but may also cause safety hazards due to electrostatic discharge. At the same time, static electricity can also cause the film to stick together and shift its position during the processing, interfering with the normal production process.

[0003] Traditional static eliminators are often installed with rigid supports. When the film moves at high speed (especially in dynamic processing scenarios such as slitting machines and winding machines), the film surface will cause the surrounding air to form turbulent airflow. These airflows can easily cause the supporting components of the device (such as connecting brackets and cables) to become entangled with the film, or cause wrinkles on the film surface due to airflow disturbance. Entanglement not only forces the production line to stop for cleaning, seriously affecting production efficiency, but may also cause the film to tear or break, increasing raw material loss. Wrinkles, on the other hand, will directly lead to the finished film not meeting the flatness standards, reducing the product qualification rate and causing economic losses to enterprises.

[0004] There is an urgent need for improvement, so we propose a soft rope-like intelligent anti-tangling film static elimination device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a soft, rope-like intelligent anti-tangling film static elimination device, which achieves the effect of preventing the film from getting tangled during movement.

[0006] In view of this, the present invention provides a flexible rope-shaped intelligent anti-tangling film static elimination device, comprising: a flexible circuit board, on which an electrostatic voltage sensor, a negative ion generator, a microcontroller, and a three-color LED indicator are sequentially mounted along its length, and the electrostatic voltage sensor, the negative ion generator, and the three-color LED indicator are electrically connected to the microcontroller. The electrostatic voltage sensor is used to collect the electrostatic voltage signal on the film surface and transmit it to the microcontroller. The microcontroller is used to control the negative ion generator according to the received electrostatic voltage signal. The three-color LED indicator is used to display the working status of the device according to the control signal of the microcontroller. A rope is provided on both sides of the flexible circuit board, and an anti-tangling guiding mechanism is provided on the rope. The anti-tangling guiding mechanism is used to guide the airflow generated during the movement of the film and divert it to both sides of the flexible circuit board. An installation adjustment component is provided at the other end of the rope. The installation adjustment component is used to position the flexible circuit board and adjust the gap between the flexible circuit board and the film. A connection positioning component is provided at both ends of the rope. The connection positioning component is used to connect both ends of the rope to the flexible circuit board and the installation adjustment component, respectively.

[0007] Furthermore, the anti-tangling guiding mechanism includes a spiral guiding groove formed on the rope body.

[0008] Furthermore, the installation adjustment assembly includes a mounting frame disposed at the outer end of the rope body, two first bolts being threaded onto the side wall of the mounting frame, an adjustment cylinder being disposed at one end of the mounting frame, an adjustment cavity being provided inside the adjustment cylinder, and the adjustment cavity being slidably connected to one end of the mounting frame.

[0009] Furthermore, the mounting bracket is inverted J-shaped, and the inner side of the mounting bracket corresponds to the slitting machine bracket.

[0010] Furthermore, a second bolt is threaded onto the side wall of the adjusting cylinder, the second bolt penetrating the adjusting cylinder to the inner cavity of the adjusting cylinder and abutting against the side wall of the mounting bracket.

[0011] Furthermore, the connection positioning assembly includes connectors that pass through both ends of the two ropes. The four connectors are respectively fixedly connected to the side walls of the two adjusting cylinders and both sides of the flexible circuit board. Each end of the rope has a rope head, and a wire rope clamp is detachably installed on the outside of the rope head. The wire rope clamp abuts against the side wall of the connector.

[0012] Furthermore, the connector has a through hole in the middle, which corresponds to the end of the rope.

[0013] The beneficial effects of this utility model are: By integrating an electrostatic voltage sensor, a negative ion generator, a microcontroller, and a three-color LED indicator on a flexible circuit board, the device can monitor the electrostatic voltage on the film surface in real time and precisely trigger the negative ion generator to eliminate static electricity through the microcontroller. The three-color LED indicator provides intuitive feedback on the device's operating status, solving the problem of blind elimination and opaque status in traditional static elimination devices, thus improving the accuracy and controllability of static elimination. An anti-entanglement guiding mechanism is set on the rope, which can guide the airflow generated during film movement and divert it to both sides, avoiding airflow turbulence that could cause the rope to entangle with the film or wrinkles on the film surface. This reduces equipment downtime or film damage caused by entanglement and improves production efficiency. Attached Figure Description

[0020] Reference Figures 1 to 3 A soft, rope-like intelligent anti-tangling film static eliminator includes: A flexible circuit board 1 is provided, on which an electrostatic voltage sensor 11, a negative ion generator 12, a microcontroller 13, and a tri-color LED indicator 14 are sequentially mounted along its length. The electrostatic voltage sensor 11, the negative ion generator 12, and the tri-color LED indicator 14 are electrically connected to the microcontroller 13. The electrostatic voltage sensor 11 is used to collect the electrostatic voltage signal on the surface of the thin film and transmit it to the microcontroller 13. The microcontroller 13 is used to control the negative ion generator 12 according to the received electrostatic voltage signal. The tri-color LED indicator 14 is used to display the working status of the device according to the control signal of the microcontroller 13. The flexible circuit board 1 has ropes 2 on both sides, and anti-entanglement guiding mechanisms are provided on the ropes 2. The anti-entanglement guiding mechanisms are used to guide the airflow generated during the movement of the film and divert it to both sides of the flexible circuit board 1. An adjustment assembly is installed at the other end of the rope 2. The adjustment assembly is used to position the flexible circuit board 1 and adjust the gap between the flexible circuit board 1 and the film. The connecting positioning components are located at both ends of the rope body 2 and are used to connect both ends of the rope body 2 to the flexible circuit board 1 and the installation adjustment component, respectively.

[0021] During operation, the electrostatic voltage sensor 11 on the flexible circuit board 1 continuously detects the electrostatic voltage on the film surface and transmits the detected voltage signal to the microcontroller 13 in real time. The microcontroller 13 analyzes and processes the signal. When the detected electrostatic voltage exceeds a preset threshold, it immediately sends a start command to the negative ion generator 12. The negative ion generator 12 starts and releases negative ions, which neutralize the static charge on the film surface, thus eliminating static electricity. At the same time, the microcontroller 13 controls the three-color LED indicator 14 to switch between different colors according to the equipment's operating status, providing intuitive feedback on the equipment's operation so that operators can monitor the status in real time. During high-speed film movement (such as slitting and winding), the film surface will drive the surrounding air to form an airflow. The anti-winding guide mechanism on the rope 2 guides this airflow. After entering the anti-winding guide mechanism, the airflow is directed to both sides to prevent the airflow from forming turbulent vortices near the rope 2. Turbulent vortices are the cause of the rope 2 and film entanglement. The main reason for surface wrinkles is that the directional diversion of airflow ensures that the rope 2 and the film maintain a relatively stable positional relationship and do not become entangled. During installation, the device is fixed on the target bracket (such as a slitting machine bracket) by installing the adjustment component. First, determine the approximate installation position of the device, and then adjust the gap between the device and the film by adjusting the component. This ensures that the negative ions released by the negative ion generator 12 can effectively cover the film surface. If the gap is too large, the number of negative ions reaching the film surface will decrease, and static electricity will not be completely eliminated. If the gap is too small, the device is prone to friction with the film, which may generate new static electricity or damage the film. Through the precise control of the adjustment component, the gap can be stabilized within the optimal range to meet the needs of different film specifications. The connection positioning component connects the rope 2 to the flexible circuit board 1 and the rope 2 to the installation adjustment component. During the operation of the device, the connection part must withstand the tension of the rope 2 to avoid excessive local stress that may cause the connection to loosen or fall off, and ensure that all functional components can work together continuously.

[0022] In the example of this application, the anti-tangling guide mechanism includes a spiral guide groove 21 opened on the rope body 2.

[0023] As a preferred example of this utility model, when the membrane moves at high speed, it pushes the surrounding air to form an airflow along the direction of membrane movement. If this airflow directly acts on the rope 2, it is easy to form irregular vortices around the rope 2. The vortices will cause the rope 2 to deviate towards the membrane, thereby causing entanglement. The spiral guide groove 21 on the rope 2 has a specific spiral trajectory. When the airflow comes into contact with the spiral guide groove 21, it will flow along the spiral path of the guide groove. The spiral structure allows the airflow to be gradually guided to both sides of the rope 2, realizing directional diversion and avoiding the accumulation of airflow around the rope 2 to form vortices. At the same time, the trajectory design of the spiral guide groove 21 makes the airflow diversion process smoother and more uniform, and will not generate new local airflow disturbances due to diversion, further reducing the risk of entanglement.

[0024] In the example of this application, the installation adjustment component includes a mounting bracket 3 provided at the outer end of the rope body 2. The side wall of the mounting bracket 3 has a first screw hole, and two first bolts 31 are installed in the internal thread of the first screw hole. One end of the mounting bracket 3 is provided with an adjustment cylinder 32, and an adjustment cavity 33 is provided inside the adjustment cylinder 32. The adjustment cavity 33 is slidably connected to one end of the mounting bracket 3.

[0025] As a preferred example of this utility model, during installation, the contact surface of the mounting frame 3 is aligned with the outer wall of the equipment support (such as the slitting machine support) so that the mounting frame 3 fits tightly against the support. At this time, the two first bolts 31 on the side wall of the mounting frame 3 correspond to different fixing points of the support. Tightening the two first bolts 31 will cause the bolt ends to abut tightly against the outer wall of the support, generating clamping force and firmly fixing the mounting frame 3 to the support. The adjustment cavity 33 inside the adjustment cylinder 32 and one end of the mounting frame 3 have a sliding fit structure, and the two can slide relative to each other along the length direction of the mounting frame 3. When it is necessary to adjust the gap between the equipment and the film, there is no need to disassemble the mounting frame 3. Just push the adjustment cylinder 32, and the adjustment cylinder 32 will drive the rope 2 connected to it. The rope 2 will then drive the flexible circuit board 1 to move synchronously, thereby changing the distance between the flexible circuit board 1 and the film and realizing the gap adjustment.

[0026] In the example of this application, the mounting bracket 3 is inverted J-shaped, and the inner side of the mounting bracket 3 corresponds to the slitting machine bracket.

[0027] As a preferred example of this utility model, the slitting machine support is mostly a frame structure. The inner shape of the inverted J-shaped mounting bracket 3 matches the outer wall contour of the slitting machine support. During installation, the inner side of the inverted J-shaped mounting bracket 3 can completely fit against the outer wall of the support. The inverted J-shaped structure has a larger contact area and a tighter contact, which can effectively distribute the weight of the mounting bracket 3 itself and the equipment, avoid local stress concentration caused by the mounting bracket 3 not fitting tightly, and reduce the risk of loosening.

[0028] In the example of this application, the side wall of the adjusting cylinder 32 is provided with a second screw hole, and a second bolt 34 is installed in the internal thread of the second screw hole. The second bolt 34 abuts against the side wall of the mounting bracket 3.

[0029] As a preferred example of this utility model, after adjusting the gap between the equipment and the film using the adjusting cylinder 32, the position of the adjusting cylinder 32 needs to be fixed to prevent the adjusting cylinder 32 from sliding due to vibration during equipment operation, which would cause the gap to shift. At this time, the second bolt 34 on the side wall of the adjusting cylinder 32 is tightened. Since the bolt and the adjusting cylinder 32 are connected by threads, the bolt will move along the thread axis towards the mounting frame 3 during the tightening process until the end of the bolt is tightly abutted against the side wall of the mounting frame 3. Static friction will be generated between the end of the bolt and the side wall of the mounting frame 3. This static friction can counteract the sliding tendency of the adjusting cylinder 32 caused by vibration, thereby locking the position of the adjusting cylinder 32 and ensuring that the gap between the equipment and the film is kept at the optimal value after adjustment, thus ensuring the stability of the electrostatic elimination effect. When the gap needs to be adjusted again, simply loosen the second bolt 34, the static friction will disappear, and the adjusting cylinder 32 can slide along the mounting frame 3 again to adjust the gap. The operation is convenient and supports repeated adjustments according to changes in film specifications.

[0030] In the example of this application, the connection positioning component includes connectors 23 that pass through both ends of the two ropes 2. The four connectors 23 are fixedly connected to the side walls of the two adjusting cylinders 32 and the two sides of the flexible circuit board 1, respectively. Both ends of the ropes 2 are provided with rope heads 22. A wire rope clamp 25 is detachably installed on the outside of the rope head 22. The wire rope clamp 25 abuts against the side wall of the connector 23.

[0031] As a preferred example of this utility model, the two ends of the rope 2 are respectively inserted into the through holes 24 of the connector 23. The four connectors 23 are respectively fixed to the side wall of the adjusting cylinder 32 and the two sides of the flexible circuit board 1. This connection can transmit the tension of the rope 2 to the adjusting cylinder 32 and the flexible circuit board 1. Steel wire rope clips 25 are installed on the outside of the rope ends 22 at both ends of the rope 2. Tightening the steel wire rope clips 25 will generate a clamping force on the rope ends 22, so that the rope ends 22 are fixed in the through holes 24 of the connector 23. The outside of the clips is in close contact with the side wall of the connector 23, preventing the rope 2 from loosening or falling out of the connector 23, and ensuring the reliability of the overall structure.

[0032] It should be noted that the wire rope clamp 25 has a detachable structure. When the rope body 2 needs to be replaced due to wear, breakage or other reasons caused by long-term use, simply loosen the bolt of the wire rope clamp 25 to remove the clamp from the rope head 22. Then, pull the old rope body 2 out of the through hole 24 of the connector 23. After replacing the new rope body 2, reinstall the wire rope clamp 25 and tighten it.

[0033] In the example of this application, a through hole 24 is provided through the middle of the connector 23, and the through hole 24 corresponds to the rope end 22.

[0034] As a preferred example of this utility model, the inner diameter of the through hole 24 matches the outer diameter of the rope end 22. During assembly, the rope end 22 can be directly inserted into the through hole 24. The inner wall of the through hole 24 guides the rope end 22, preventing it from shifting or misaligning during insertion and ensuring that the rope end 22 can be quickly and accurately inserted into the connector 23, thereby improving assembly efficiency.

[0035] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
