Description

Technical Field

[0001] This utility model relates to the technical field of material processing equipment, and in particular to a variable width switching safety locking device. Background Technology

[0002] In continuous material processing such as films, fabrics, and metal strips, due to diversified market demands, a single production line needs to be capable of processing materials of various widths in order to effectively improve equipment utilization and reduce production line configuration costs. This requires the related supporting equipment to have a certain degree of flexibility and adaptability. For this reason, the winding device usually uses a material shaft lateral adjustment component to drive the material shaft drive component to move along a linear guide rail to achieve the winding of materials of different widths.

[0003] Existing transverse adjustment assemblies for material shafts mostly employ a ball screw structure driven by a motor. After the width is adjusted, positioning is achieved through the self-locking force of this structure. However, during equipment operation, this positioning method is prone to displacement problems due to factors such as equipment vibration and material tension fluctuations. This can lead to deviations in winding width, decreased processing accuracy, and even equipment collision accidents, affecting production efficiency and equipment safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a variable width switching safety locking device that provides stable positioning and locking to prevent displacement and ensure safe operation of equipment.

[0005] This utility model discloses a variable width switching safety locking device, comprising a locking drive, a locking pin, a locking seat, and a locking detection component. The locking drive is mounted on the movable frame of the material shaft lateral adjustment assembly, and the locking pin is mounted on the output end of the locking drive. The locking seat is mounted on the fixed frame of the material shaft lateral adjustment assembly and extends parallel to the sliding direction of the movable frame. The locking seat is provided with an array of pin holes, which are distributed along the extending direction of the locking seat. The locking drive is used to drive the locking pin to insert into or withdraw from the pin holes, locking the movable frame at the position corresponding to the target width. The locking detection component is mounted in the pin holes and is provided corresponding to the protruding end of the locking pin, used to detect whether the locking pin is fully inserted into the pin holes.

[0011] As a preferred embodiment of this utility model, it also includes a position detection component, which is connected to the controller for detecting the real-time position of the movable frame; the controller controls the drive motor of the material shaft lateral adjustment component to stop when the movable frame reaches the target position based on the detection signal from the position detection component.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Reference Figures 1-3This embodiment provides a variable width switching safety locking device, including a locking drive 1, a locking pin 2, a locking seat 3, and a locking detection element 4. The locking drive 1 is fixedly mounted on the movable frame 5 of the material shaft lateral adjustment assembly. This mounting allows the locking drive 1 to move synchronously with the movable frame 5, ensuring that the locking drive 1 maintains a corresponding active position with the locking seat 3 when the movable frame 5 reaches any target width position. The locking pin 2 is coaxially fixed to the output end of the locking drive 1, allowing the locking drive 1 to directly drive the locking pin 2 in linear reciprocating motion. The locking seat 3 is fixedly mounted on the fixed frame 6 of the material shaft lateral adjustment assembly, and the extension direction of the locking seat 3 is parallel to the sliding direction of the movable frame 5. Its extension length is adapted to the moving length of the movable frame 5, ensuring that the locking pin 2 always maintains a corresponding position with the locking seat 3 when the movable frame 5 moves throughout the entire width adjustment range. The fixed seat 3 has an array of pin holes 31, which are evenly distributed or at preset width intervals along the extension direction of the locking seat 3. Each pin hole 31 corresponds to a target processing width. By setting the pin hole 31 array, precise positioning of multiple widths can be achieved. During operation, when the movable frame 5 drives the material shaft drive assembly to the position corresponding to the target width, the locking drive component 1 can receive the controller's command and drive the locking pin 2 to insert into the corresponding pin hole 31 axially. The mechanical cooperation between the locking pin 2 and the pin hole 31 achieves rigid locking of the movable frame 5, avoiding positioning displacement problems. When it is necessary to switch the width, the locking drive component 1 can drive the locking pin 2 to be pulled out of the pin hole 31. After the lock is released, the movable frame 5 can be moved and adjusted again. To ensure the reliability of the locking action, the locking detection element 4 is embedded in the pin hole 31, and its installation position corresponds to the protruding end of the locking pin 2. It can directly detect whether the locking pin 2 is fully inserted into the pin hole 31, avoiding locking failure due to the locking pin 2 not being fully inserted. Both the locking drive element 1 and the locking detection element 4 are connected to the controller of the winding device. When the locking detection element 4 detects that the locking pin 2 is fully inserted into the pin hole 31, it will send a position signal to the controller, and the controller will then allow the winding device to start running. If the position signal is not detected, the controller will prohibit the equipment from running and issue an alarm, forming a closed-loop control, improving the safety of equipment operation, and avoiding the decrease in processing accuracy and equipment collision accidents caused by locking failure.

[0018] To improve the stability and force balance of locking and avoid displacement or structural deformation caused by unilateral force on the movable frame 5, the locking drive component 1 and the corresponding locking pin 2, locking seat 3, and locking detection component 4 constitute a complete locking unit. At least two locking units are set, and the two sets of locking units are symmetrically arranged on both sides of the movable frame 5. The symmetrical arrangement can make the movable frame 5 subject to uniform locking force on both sides. When locking, the movable frame 5 will not generate overturning moment due to unilateral force, thereby further improving the positioning accuracy.

[0019] The locking drive component 1 can be selected from different types according to the power requirements, installation space, and cost budget of the actual application scenario. Specifically, it can be a cylinder, a hydraulic cylinder, or an electromagnetic drive component. Among them, the cylinder provides driving force through compressed air and has the advantages of fast response speed, simple structure, low maintenance cost, and cleanliness without oil stains. It is suitable for processing medium and light materials and scenarios with high locking speed requirements. The hydraulic cylinder can provide greater thrust and high locking strength. It is suitable for processing heavy materials and high tension scenarios and can effectively resist the effects of strong vibration and high tension. The electromagnetic drive component has the characteristics of compact structure, high control precision, frequent start and stop, and no noise. It is suitable for processing scenarios with limited installation space and high frequency amplitude switching.

[0020] To accommodate different machining accuracy requirements and installation error compensation needs, the pin hole 31 can be designed as a tapered hole, an oblong hole, or a round hole, and the end shape of the locking pin 2 matches the shape of the pin hole 31. When the pin hole 31 is a tapered hole, the end of the locking pin 2 is correspondingly designed as tapered. The tapered structure has an automatic guiding function. Even if there is a slight deviation in the stopping position of the movable frame 5, the locking pin 2 can be smoothly inserted into the pin hole 31 through the guiding effect of the tapered surface. At the same time, the tapered fit can increase the contact area, improve the locking firmness, and reduce the risk of damage. Loosening caused by vibration; when the pin hole 31 is an oblong hole, its length direction is consistent with the sliding direction of the movable frame 5, which can compensate for the small displacement caused by thermal expansion and contraction or material tension fluctuation due to installation errors, temperature changes, etc., and avoid jamming between the locking pin 2 and the pin hole 31, ensuring the smoothness of locking and unlocking actions; when the pin hole 31 is a round hole, the end of the locking pin 2 is cylindrical, the matching positioning accuracy of the round hole and the cylindrical surface is high, the structure is simple to process, and it is suitable for processing scenarios with strict positioning accuracy requirements and stable working conditions.

[0021] The locking detection component 4 can be either a proximity switch or a limit switch to adapt to different working environments. The proximity switch adopts a non-contact detection method, which determines whether the locking pin is in place by sensing the metal material at the end of the locking pin 2 or a preset sensing surface. It has the advantages of no mechanical wear, fast response speed, and long service life. It is suitable for high-frequency locking switching, dusty or humid processing environments, and can avoid detection errors caused by wear in contact detection. The limit switch adopts a contact detection method. Its trigger end corresponds to the end of the locking pin 2. When the locking pin 2 is fully inserted into the pin hole 31, the end of the locking pin 2 presses the trigger end of the limit switch, and the limit switch sends out a signal indicating that the locking pin is in place. This detection method has a simple structure, high detection accuracy, and strong anti-interference ability. It is suitable for processing scenarios with extremely high requirements for detection reliability and large vibration.

[0022] To further enhance the locking reliability between the locking pin 2 and the pin hole 31, and to extend the service life of the component, an anti-slip and wear-resistant layer is provided on the contact surface between the locking pin 2 and the pin hole 31. The anti-slip and wear-resistant layer can be made of tungsten carbide coating, ceramic coating, polyurethane wear-resistant layer, or titanium nitride coating, etc. Among them, tungsten carbide coating has high hardness and strong wear resistance, and is suitable for high tension and high frequency locking scenarios; ceramic coating has excellent high temperature resistance, wear resistance and anti-slip performance, and is suitable for material processing in high temperature environments; polyurethane wear-resistant layer has a certain degree of elasticity, which can buffer the impact force during locking, while increasing the friction of the contact surface and avoiding minor displacement caused by vibration; titanium nitride coating has the characteristics of wear resistance, corrosion resistance and low coefficient of friction, which can reduce the frictional resistance during locking and unlocking and improve the smoothness of operation. The anti-slip and wear-resistant layer can reduce the wear between the locking pin 2 and the pin hole 31 and extend the service life of the component.

[0023] Considering that the stopping position accuracy of the movable frame 5 directly affects the fitting effect between the locking pin 2 and the pin hole 31 during width adjustment, this device also includes a position detection component 7. The position detection component 7 is connected to the controller and is used to detect the position information of the movable frame 5 in real time and feed the detection signal back to the controller. Based on the feedback signal from the position detection component 7, the controller precisely controls the drive motor of the material shaft lateral adjustment component. When the movable frame 5 moves to the preset position corresponding to the target width, the controller issues a stop command, and the drive motor immediately stops running. Through the real-time monitoring of the position detection component 7, it can be ensured that the movable frame 5 can accurately stop at the target position, so that the locking pin 2 and the corresponding pin hole 31 are accurately aligned, avoiding the situation where the locking pin 2 cannot be inserted or is not inserted properly due to position deviation, further improving the accuracy of width adjustment and the reliability of locking action.

[0024] To achieve accurate identification and positioning of different target widths, the position detection component 7 includes a position sensor 71 and a position marker 72. The position markers 72 are fixedly set on the fixed frame 6 at preset intervals along the sliding direction of the movable frame 5, and each position marker 72 uniquely corresponds to a target processing width. The interval distance of the position markers 72 is preset according to the specifications of common processing widths to ensure coverage of all widths that need to be processed. The position sensor 71 is fixedly installed on the movable frame 5 and moves synchronously with the movable frame 5. When the movable frame 5 moves, the position sensor 71 scans the position markers 72 on the fixed frame 6 in real time. When it identifies a position marker 72 corresponding to the target width, it immediately sends a position signal to the controller. After receiving the signal, the controller controls the drive motor to stop, thereby achieving accurate positioning of the movable frame 5.

[0025] The types of position markers 72 and position sensors 71 can be flexibly selected according to the processing environment, accuracy requirements, and cost budget. Position markers 72 can be magnetic, optical, or mechanical, while the corresponding position sensors 71 can be magnetic, optical, or mechanically triggered. Magnetic markers use permanent magnets or magnetic patches, which have the advantages of strong anti-interference ability, moisture resistance, and dust resistance, making them suitable for harsh processing environments. The corresponding magnetic sensors identify position markers 72 by sensing changes in the magnetic field, with high detection accuracy and fast response speed. Optical markers can be QR codes, barcodes, or reflective markers, with extremely high positioning accuracy, capable of precise positioning with small amplitude increments, suitable for scenarios with stringent processing accuracy requirements. The corresponding optical sensors achieve position recognition by reading information from the optical markers, with a high degree of automation. Mechanical markers can use structures such as bosses, grooves, or positioning holes, with simple structures, low cost, and high reliability, suitable for scenarios with low accuracy requirements and limited maintenance conditions. The corresponding mechanically triggered sensors achieve position detection through physical contact with the mechanical markers, with extremely strong anti-interference ability.
