Description

Technical Field

[0001] This invention relates to the field of pressing device technology, specifically a pressing device for a shielding door. Background Technology

[0002] Shielding doors typically contain radiation-shielding lead plates and other materials to achieve their shielding purpose and protect the human body from various types of radiation. Therefore, during the manufacturing process, shielding doors require pressing to ensure the lead plates and other materials are properly pressed into the door.

[0003] Current shielding door pressing devices consist of a pressing mold and a pressing plate. During pressing, the pressing material is placed inside the pressing mold, and then an external drive component drives the pressing plate to apply pressure to the material inside the mold, thus obtaining the pressed shielding door. However, because the pressing mold contains a groove, after the shielding door is pressed, it will be completely embedded inside the groove. When unloading, it needs to be pried up from the side, which affects the unloading efficiency and is inconvenient. It also requires manual lifting and unloading, which is time-consuming and labor-intensive. Furthermore, after pressing, some debris and impurities remain inside the pressing mold. If not cleaned in time, it will affect the quality of subsequent pressing. Summary of the Invention

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-9As shown, the pressing device for a shielding door according to the present invention includes a frame 1, a pressing mold 2 fixedly connected to the top of the frame 1, a pressing structure 3 installed on the top of the pressing mold 2, a top material structure 4 provided on the pressing structure 3, a pushing structure 5 installed on the pressing mold 2, a flipping structure 6 and an anti-reset structure 7 provided on the pushing structure 5, a collecting structure 8 installed on the right side of the pressing mold 2, and a conveying assembly 9 arranged on the left side of the pressing mold 2.

[0032] The pressing structure 3 includes a pressing plate 303. A column 301 is installed on the back of the frame 1. A hydraulic press 302 is installed at the top and bottom of the column 301. The bottom of the hydraulic press 302 is detachably connected to the pressing plate 303. When the hydraulic press 302 works, it drives the pressing plate 303 to the top, so that the top of the pressing mold 2 has enough operating space. Then, the shielding door material to be pressed is placed inside the pressing mold 2, and then the pressing plate 303 is driven to start pressing the shielding door inside the pressing mold 2.

[0033] The top material structure 4 includes a top material plate 401, which is slidably connected inside the mold groove of the pressing mold 2. Two guide pillars 402 are fixedly connected to the bottom end of the top material plate 401, and the two guide pillars 402 penetrate the pressing mold 2 and are slidably connected to the pressing mold 2. Each of the two guide pillars 402 is provided with a lifting groove 403. Two connecting rods 404 are fixedly connected to the pressing plate 303, and the two connecting rods 404 penetrate the side of the pressing mold 2 and are slidably connected to the pressing mold 2. The bottom ends of the two connecting rods 404 slide inside the lifting groove 403. The rectangular pressing mold 2 has a rectangular mold groove inside, and the shape and size of the top material plate 401 and the pressing plate 303 are the same as the shape and size of the mold groove.

[0034] The hydraulic press 302 drives the pressing plate 303 to rise. Since the top of the connecting rod 404, which slides inside the lifting groove 403, is connected to the pressing plate 303, the connecting rod 404 will start to rise under the drive of the pressing plate 303. At this time, the connecting rod 404 is still sliding inside the lifting groove 403. When the connecting rod 404 slides to the top of the lifting groove 403, it will start to rise against the two guide posts 402. Since the guide posts 402 are connected to the top plate 401 inside the pressing mold 2, the top plate 401 can be driven to rise and lift the shielding door inside the pressing mold 2 at the same time as the pressing plate 303 rises and resets. This allows the pressed shielding door to be fully exposed in the pressing mold 2, making it convenient to unload the shielding door.

[0035] Specifically, the pushing structure 5 includes a housing 501. A hollow housing 501 is installed on the side wall of the pressing mold 2. A lead screw 508 is rotatably connected inside the housing 501. A threaded block 503 is threadedly connected to the outside of the lead screw 508. The threaded block 503 is slidably connected inside the housing 501. A groove 507 is provided on the front wall of the housing 501. A slider 504 is slidably connected inside the groove 507. The slider 504 is connected to the threaded block 503. An mounting plate 505 is fixedly connected to the front end of the slider 504. A pushing plate 506 is fixedly connected to the bottom of the mounting plate 505. A motor 502 is installed on the right side of the housing 501. The output shaft of the motor 502 is connected to the end of the lead screw 508 through a coupling. The slider 504 has a cuboid structure.

[0036] Motor 502 drives lead screw 508 to rotate, which in turn drives threaded block 503 to slide to the left inside housing 501. Since mounting plate 505 is connected to threaded block 503 via slider 504 and rotating rod 601, push plate 506 at the bottom of mounting plate 505 slides to the left side of the equipment. This pushes the shielding door of the pressing mold 2 from the pressing mold 2 to the left, and finally pushes it onto conveying assembly 9 for transport to the next process. This achieves fully automatic unloading, which is convenient, fast, and greatly improves unloading efficiency, while also saving labor.

[0037] Specifically, the flipping structure 6 includes a rotating rod 601, which is rotatably connected inside the threaded block 503. The front end of the rotating rod 601 is fixedly connected to the slider 504, and the rear end of the rotating rod 601 is fixedly connected to a gear 602. Racks 603 are installed at both the left and right ends inside the housing 501, and the gear 602 can mesh with the two racks 603. Transfer grooves 605 are provided at both the left and right ends of the slide groove 507, and the height of the transfer grooves 605 is greater than the height of the slide groove 507. A cleaning brush 604 is detachably connected to the top of the mounting plate 505.

[0038] Specifically, the anti-reset structure 7 includes an abutment block 701, which is fixedly connected to the bottom end of the threaded block 503. The bottom end of the abutment block 701 has a smooth arc-shaped structure. Both racks 603 are slidably connected to the housing 501. A connecting plate 702 is fixedly connected to the opposite ends of the two racks 603. An abutment post 703 is fixedly connected to the front end of the connecting plate 702. The abutment block 701 can abut against the abutment post 703, thereby driving the racks 603 downward. A sliding plate 705 is fixedly connected inside the housing 501. An L-shaped abutment groove 706 is formed on the fixed plate 705. An abutment post 703 is slidably connected inside the abutment groove 706. An L-shaped hook rod 709 is also movably connected inside the housing 501. A sliding plate 710 is fixedly connected to the left side of the hook rod 709. A fixed post 711 is also fixedly connected inside the housing 501. An inclined groove is formed on the sliding plate 710. 712, the sliding plate 710 is movably connected to the fixed column 711 via the inclined groove 712. The top of the sliding plate 710 has a trapezoidal structure, and in the normal state, its top surface is higher than the bottom surface of the threaded block 503. A roller 704 is rotatably connected to the abutting column 703, and the abutting block 701 slides against the roller 704. Two first guide rods 707 are fixedly connected to the bottom ends of the two racks 603, and the two racks 603 are respectively connected to the two first guide rods 707. The rod 707 is slidably connected to the housing 501. Two first springs 708 are installed at the bottom of the two racks 603 respectively to allow the racks 603 to reset after being pressed down. Two second guide rods 713 are fixedly connected at the bottom of the two hook rods 709 at an incline. The two hook rods 709 are slidably connected to the housing 501 at an incline through the two second guide rods 713 respectively. Two second springs 714 are installed at the bottom of the two hook rods 709 respectively to allow the hook rods 709 to reset after being pressed down.

[0039] When the threaded block 503 slides to the left and pushes the shielding door out completely, the shielding door will be conveyed away by the conveying assembly 9. At this time, the gear 602 on the rotating rod 601 will mesh with the rack 603. Since the length of the rack 603 is only half the circumference of the gear 602, when the gear 602 has completely passed the rack 603, the rotating rod 601 will have rotated half a turn, or 180°. At this time, the pusher plate 506 and the cleaning brush 604 on the mounting plate 505 will be interchanged, and the cleaning brush 604 will be at its lowest point. Moreover, because there is sufficient rotational friction between the rotating rod 601 and the threaded block 503, it can be ensured that the rotating rod 601 will not rotate on its own after rotation. Furthermore, because there are openings at both ends of the slide groove 507... A sufficiently high transfer groove 605 is provided. This means that when the slider 504 slides inside the groove 507, the groove 507 limits the slider 504, allowing it to slide horizontally left and right without rotation. Only when the slider 504 disengages from the groove 507 and reaches the position of the transfer groove 605, which is exactly when the gear 602 meshes with the rack 603, will the rotating rod 601 drive the slider 504 to rotate. This ensures the normal switching between pushing and cleaning. After the rotating rod 601 rotates 180°, the gear 602 has completely passed the rack 603. At this point, the abutment block 701 at the bottom of the threaded block 503 will begin to abut against the abutment post 703 on the mounting plate 505. Because the rack 60... 3. The rack 603 slides up and down with the housing 501 via the first spring 708 and the first guide rod 707. Under normal conditions, the rack 603 is at its highest point under the elastic force of the first spring 708 to ensure that the gear 602 can mesh with the rack 603. When the abutment block 701 abuts against the abutment post 703, the abutment block 701 applies pressure to the abutment post 703, and the abutment post 703 slides down under the pressure of the abutment block 701, simultaneously driving the rack 603 down. When the abutment post 603 slides down to the lowest end of the abutment groove 706, since the abutment groove 706 has an L-shaped structure, the abutment post 703 slides into the bottom horizontal groove of the abutment groove 706, at which point the abutment post 703 is limited, which is the point at which... When rack 603 slides down to the point where it no longer meshes with gear 602, it ensures that when threaded block 503 is reverse-driven by screw 508 to clean to the right, gear 602 will no longer mesh with rack 603. This prevents gear 602 from driving rotating rod 601 back to its original position, ensuring normal cleaning operation. When threaded block 503 slides to the right, since the top surface of sliding plate 710 is higher than the bottom surface of threaded block 503, it will first contact sliding plate 710, driving sliding plate 710 to move. Because sliding plate 710 will tilt downwards under the action of fixed post 711 and inclined groove 712, threaded block 503 will drive sliding plate 710 to tilt downwards.Until the sliding plate 710 no longer abuts against the threaded block 503, the threaded block 503 will slide directly past the sliding plate 710. While the sliding plate 710 is tilting and sliding, it will also drive the hook rod 709 to push out the abutment post 703 inside the abutment groove 706. When the abutment post 703 slides into the vertical groove of the abutment groove 706, it will automatically reset under the elastic force of the first spring 708, ensuring the normal operation of the next switching operation. When the cleaning brush 604 slides to the right, it can be flipped back again by the flipping structure 6, thus preparing for the next material pushing operation.

[0040] Specifically, the collection structure 8 includes an anti-detachment groove 802. An anti-detachment groove 802 with a trapezoidal cross-section is provided on the right side of the pressing mold 2. An anti-detachment block 803 with a trapezoidal cross-section is slidably connected inside the anti-detachment groove 802. The anti-detachment block 803 is fixedly connected to the collection box 801. The collection box 801 is detachably connected to the pressing mold 2 through the anti-detachment groove 802 and the anti-detachment block 803. The debris and debris swept back by the cleaning brush 604 will flow into the collection box 801 for collection and storage to avoid polluting the ground. The collection box 801 can also be quickly disassembled and assembled through the anti-detachment groove 802 and the anti-detachment block 803, which is convenient and practical.

[0041] In use, the hydraulic press 302 is first connected to an external hydraulic system, and the motor 502 is electrically connected to an external power source to ensure the normal operation of the entire power system. Then, the hydraulic press 302 operates, driving the pressing plate 303 to rise to the top, leaving sufficient operating space at the top of the pressing mold 2. The shielding door material to be pressed is then placed inside the pressing mold 2, and the pressing plate 303 is driven to begin pressing the shielding door inside the pressing mold 2. After pressing is complete, the hydraulic press 302 begins to lift the pressing plate 303. The connecting rod 404, which slides inside the lifting groove 403, connects to the pressing plate 303 at its top. At this time, the connecting rod 404 will start to rise under the drive of the pressing plate 303. That is, the connecting rod 404 is still sliding inside the lifting groove 403. When the connecting rod 404 slides to the top of the lifting groove 403, the connecting rod 404 will start to rise against the two guide posts 402. Since the guide posts 402 are connected to the top plate 401 inside the pressing mold 2, that is, while the pressing plate 303 rises and resets, it can drive the top plate 401 to rise and lift the shielding door inside the pressing mold 2. That is, it can make the pressed shielding door completely exposed in the pressing mold 2, which makes it convenient to unload the shielding door.

[0042] Then, motor 502 starts working, driving lead screw 508 to rotate. Lead screw 508 then drives threaded block 503 to slide to the left inside housing 501. Since mounting plate 505 is connected to threaded block 503 via slider 504 and rotating rod 601, pusher plate 506 at the bottom of mounting plate 505 slides to the left side of the equipment. This pushes the shielding door ejected from pressing mold 2 to the left, finally onto conveyor assembly 9 and then to the next process, thus achieving fully automatic unloading. This is convenient, fast, and greatly improves unloading efficiency, while also saving labor. When threaded block 503 slides to the left and fully pushes the shielding door out, the shielding door is then conveyed... As component 9 is conveyed away, the gear 602 on the rotating rod 601 meshes with the rack 603. Since the length of the rack 603 is only half the circumference of the gear 602, when the gear 602 has completely passed the rack 603, the rotating rod 601 has rotated exactly half a turn, or 180°. At this point, the pusher plate 506 on the mounting plate 505 and the cleaning brush 604 are interchanged, meaning the cleaning brush 604 is now at its lowest point. Furthermore, sufficient rotational friction between the rotating rod 601 and the threaded block 503 ensures that the rotating rod 601 will not rotate on its own axis. Additionally, because a sufficiently high transfer groove 605 is provided at each end of the slide groove 507, when the slider 504 is in the slide groove 507... When sliding inside the 07, the slider 504 is limited by the slide groove 507, so the slider 504 can only slide horizontally left and right and will not rotate. Only when the slider 504 disengages from the slide groove 507 and reaches the position of the transfer groove 605, that is, when the gear 602 and the rack 603 are engaged, will the rotating rod 601 drive the slider 504 to rotate, thus ensuring the normal switching between pushing and cleaning. When the rotating rod 601 rotates 180°, the gear 602 has completely passed the rack 603, and the abutment block 701 at the bottom of the threaded block 503 will start to abut against the abutment post 703 on the mounting plate 505. Since the rack 603 is connected to the housing 50 by the first spring 708 and the first guide rod 707, the rotation rod 601 will drive the slider 504 to rotate, thus ensuring the normal switching between pushing and cleaning. 1. The rack 603 slides up and down. Under normal conditions, the rack 603 is at its highest point under the elastic force of the first spring 708, ensuring that the gear 602 can mesh with the rack 603. When the contact block 701 contacts the contact post 703, the contact block 701 applies pressure to the contact post 703, causing the contact post 703 to slide down under the pressure of the contact block 701, simultaneously driving the rack 603 down. When the contact post 603 slides down to the lowest end of the contact groove 706, because the contact groove 706 has an L-shaped structure, the contact post 703 slides into the bottom transverse groove of the contact groove 706. At this point, the contact post 703 is stopped, meaning that the rack 603 no longer meshes with the gear 602.This ensures that when the threaded block 503 is reverse-driven to the right by the lead screw 508 for cleaning, the gear 602 will no longer mesh with the rack 603, thus preventing the gear 602 from driving the rotating rod 601 back to its original position, ensuring the normal operation of the cleaning work. When the threaded block 503 slides to the right, since the top surface of the sliding plate 710 is higher than the bottom surface of the threaded block 503, the threaded block 503 will first contact the sliding plate 710, driving the sliding plate 710 to move. Because the sliding plate 710 will tilt downwards under the action of the fixed post 711 and the inclined groove 712, the threaded block 503 will drive the sliding plate 710 to tilt downwards until the sliding plate 710 no longer contacts the threaded block 503. Block 503 will then slide directly over the sliding plate 710 and continue sliding. As the sliding plate 710 slides at an angle, it will also cause the hook rod 709 to push out the contact post 703 inside the contact groove 706. When the contact post 703 slides into the vertical groove of the contact groove 706, it will automatically reset under the elastic force of the first spring 708, ensuring the normal operation of the next switching operation. When the sweeping brush 604 slides to the right, it can flip back again through the flipping structure 6, thus preparing for the next material pushing operation. The debris swept back by the sweeping brush 604 will flow into the collection box 801 for collection and storage to prevent ground contamination. The collection box 801 can also be quickly disassembled and assembled using the anti-detachment groove 802 and the anti-detachment block 803, making it convenient and practical.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
