The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] To achieve the above objectives, this utility model provides a laser engraving equipment guide rail suspension protective door device, see reference. Figures 1-6 As shown, the device includes a base plate 1, a profile plate 2, a door cover 3, a magnetic sliding block 4, a sliding assembly 5, a guide assembly 6, a guide wheel 7, and a flexible tension spring 8. The base plate 1 is provided with a vertically connected profile plate 2. The left and right sides of the profile plate 2 are connected to the left and right inner sides of the door cover 3 through the sliding assembly 5. The lower left and right inner sides of the door cover 3 are fixedly connected with magnetic sliding blocks 4. The guide assembly 6 passes through the magnetic sliding blocks 4 and is fixedly installed on the base plate 1. The two sides of the profile plate 2 are integrally connected with partitions 9. The upper part of the partitions 9 is provided with guide wheels 7. One end of the flexible tension spring 8 is fixedly connected to the base plate 1, and the other end passes through the guide wheel 7 and is connected to the magnetic sliding block 4.
[0025] In this embodiment, the base plate 1 serves as the bottom support substrate, and the profile plate 2 is vertically installed. The door cover 3 slides up and down relative to the profile plate 2. The door cover 3 is assisted by the magnetic sliding block 4, the guide component 6, the guide wheel 7, and the flexible tension spring 8. The sliding of the door cover 3 is affected by the tension of the flexible tension spring 8 and the magnetic force of the magnetic sliding block 4, which allows it to slide up and down and hover precisely. The door cover 3 can slide up and down stably along the profile plate 2. Compared with traditional hinged doors, it greatly reduces the space occupation, and the sliding resistance is small and the operation is labor-saving. At the same time, the magnetic sliding block 4 is placed below the bearing 11, so that the sliding component 5 and the hovering component are spatially staggered and do not interfere with each other, ensuring that their functions can be performed independently and stably. The guide wheel 7 is installed on the upper part of the partition plate 9 on both sides of the profile plate 2. It is used to change the force direction of the flexible tension spring 8, so that the tension direction of the flexible tension spring 8 on the magnetic sliding block 4 is consistent with the sliding direction of the door cover 3. This ensures that the tension can effectively assist the sliding. The elastic characteristics of the flexible tension spring 8 can store and release energy. When the door cover 3 slides, the tension spring stretches or contracts to generate stored force. Together with the magnetic damping, it allows the door cover 3 to quickly stabilize after stopping the push, avoiding continued sliding due to inertia and improving the reliability of the hovering.
[0026] Furthermore, the sliding assembly 5 includes a slide rail 10 integrally formed on the profile plate 2 and several bearings 11 installed inside the door cover 3. The bearings 11 are fitted into the slide rail 10 to allow the door cover 3 to slide up and down relative to the profile plate 2. The magnetic sliding block 4 is located below the bearings 11. The magnetic sliding block 4 is provided with an assembly groove 12. A section of the flexible tension spring 8 is inserted into the assembly groove 12. The side of the magnetic sliding block 4 is provided with screw holes 13 for pressing the flexible tension spring 8. Magnets 14 are provided at both the upper and lower ends of the magnetic sliding block 4. A limiting metal sheet 15 is provided in the upper part of the profile plate 2. The magnets 14 at both ends of the magnetic sliding block 4 form a limiting damping arrangement with the limiting metal sheet 15 and the base plate 1, respectively.
[0027] In this embodiment, the magnetic sliding block 4 has both connection and positioning functions. The assembly groove 12 is used to insert one end of the flexible tension spring 8. The screw hole 13 on the side is used to press the end of the flexible tension spring 8 with screws to prevent the flexible tension spring 8 from falling off or loosening during the sliding process, thus ensuring the stability of power transmission. The magnets 14 embedded at the upper and lower ends of the magnetic sliding block 4 are used to form a corresponding magnetic attraction with the limiting metal piece 15 and the base plate 1 in the upper part of the profile plate 2. When the magnetic sliding block 4 moves, the magnet 14 generates magnetic damping between the limiting metal piece 15 and the base plate 1, which can effectively counteract the inertia when the door cover 3 slides, and achieve precise positioning during hovering.
[0028] Furthermore, the guide assembly 6 includes a guide shaft 16 and a limiting block 17. The guide shaft 16 is fixedly installed on the base plate 1, and the limiting block 17 is provided at the top of the guide shaft 16. The magnetic sliding block 4 is provided with a through shaft hole 18, and the guide shaft 16 slides through the shaft hole 18 for connection.
[0029] In this embodiment, the guide component 6 serves a dual function of auxiliary guidance and stroke limitation. The guide shaft 16 and the shaft hole 18 are slidably connected, and the slide rail 10 and the bearing 11 form a dual guide arrangement to improve the straightness of the sliding of the door cover 3 and avoid deviation or jamming. The limiting block 17 limits the maximum upward distance of the magnetic sliding block 4 to prevent the door cover 3 from sliding excessively and causing component collision damage, thus ensuring the safety of device operation.
[0030] Working principle: When the protective door needs to be opened or closed, the operator pushes and pulls the door cover 3 up and down. The bearing 11 slides along the slide rail 10 of the profile plate 2, providing the main sliding support for the door cover 3. The magnetic sliding block 4 moves synchronously along the guide shaft 16 through the shaft hole 18. The slide rail 10 and the bearing 11 form a double guide, ensuring that the sliding trajectory is accurate and without deviation. During the sliding process, the flexible tension spring 8 transmits the tension through the guide wheel 7. It is stretched or compressed as the magnetic sliding block 4 moves, storing elastic potential energy. The magnets 14 at the upper and lower ends of the magnetic sliding block 4 generate magnetic damping between the limiting metal plate 15 and the base plate 1, which counteracts the sliding inertia of the door cover 3. When the pushing force is stopped, the elastic stored force of the flexible tension spring 8 and the magnetic damping balance each other, and the door cover 3 quickly stabilizes in the current position, achieving precise hovering. The limiting metal plate 15 can limit the maximum upward height of the door cover 3, and the limiting block 17 at the top of the guide shaft 16 further strengthens the stroke constraint to avoid damage to the components due to overtravel.
[0031] In one embodiment of a laser engraving equipment, the working chamber protection requirements of various small and medium-sized laser engraving machines are adapted. During installation, the base plate 1 is simply fixed to the corresponding position on the equipment frame with bolts. The outer cover 3 can be customized according to the height and width of the equipment chamber without requiring significant modifications to the main structure of the equipment, offering strong compatibility. Operators can suspend the outer cover 3 at any height by pushing and pulling it up and down. Before processing, suspending the outer cover 3 facilitates the placement of the workpiece to be processed. During processing, suspending it allows observation of the workpiece engraving progress. After processing, suspending it facilitates the removal of the finished product, making operation convenient and efficient. The outer cover 3 effectively isolates the laser radiation, processing fumes, and fine debris generated during laser engraving, protecting operators from radiation and dust damage, preventing debris from contaminating the precision optical system inside the equipment, and extending the equipment's service life. It is suitable for laser engraving processing scenarios involving various materials such as wood, plastic, and metal.
[0032] In summary, this utility model provides a guide rail suspension protective door device for laser engraving equipment. By setting up a sliding component 5 and a guide component 6, the sliding can be guided more smoothly. The magnetic sliding block 4 can slide between the limiting metal plate 15 and the base plate 1 through the upper and lower magnets 14. The flexible tension spring 8 is used to make the door cover 3 slide and suspend with damping force storage, making the suspension more precise and the positioning more accurate. The protective door is safe and reliable, with a compact structure and convenient operation, better meeting the needs of users.
