Description

Technical Field

[0001] The utility model relates to the technical field of wooden fire doors, in particular to an extrusion resistance testing device for producing wooden fire doors. Background Art

[0002] A fire door is a special door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. This door not only has the basic functions of an ordinary door, but also plays an important role in preventing the spread of fire and smoke.

[0003] During the production and processing of existing wooden fire doors, they need to be tested using a compression resistance test device. During the test, the fire door is placed on a workbench, and then a test plate is pressed against the fire door by a hydraulic mechanism for testing. However, after the test is completed, the existing testing equipment requires the staff to remove the tested fire door from the workbench and then place the untested fire door on the workbench before testing. The test speed is slow and the use effect is poor. In addition, because the fire door is exposed to the external environment during the test process, when the wooden fire door is squeezed and damaged by the test plate, the debris generated by the damage can easily splash into the external environment and injure the staff, resulting in poor protection. To this end, we propose a compression resistance test device for wooden fire doors in production. Utility Model Content

When the protective cover is rotated to be perpendicular to the fixed plate, the protective cover covers both sides of the U-shaped frame. There is a gap between the bottom of the protective cover and the top of the conveyor belt, and there is a gap between the side of the protective cover and the strip movable plate and the edge of the pressure plate.

[0010] Both sides of each protective cover are equipped with mounting seats, and the side surface of each mounting seat is connected with a telescopic mechanism through a hinge seat, and the other end of each telescopic mechanism is rotatably connected to the side surface of the U-shaped frame.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-Figure 3 A compression resistance testing device for the production of wooden fire doors includes a base 1, a control box 14 is installed on the bottom edge of the base 1, and a controller is installed in the control box 14. The controller is one of a control motherboard, a host or a PLC logic controller.

[0026] like Figure 1 As shown, strip mounting plates 2 are installed on both sides of the top of the base 1, and the adjacent surfaces of the two strip mounting plates 2 are equidistantly connected to a number of support wheels 3, and the support wheels 3 on the same side are connected by a conveyor belt 5. The outer surface of each conveyor belt 5 is provided with a receiving groove 4, and the support wheel 3 at one end is connected to a drive motor 12, which is fixed on the side of the strip mounting plate 2. The drive motor 12 is connected to the controller through a wire. In actual use, the staff places the wooden fire door in the corresponding receiving groove 4, and then the drive motor 12 can drive the conveyor belt 5 to move under the action of the support wheel 3 to transport the wooden fire door.

[0027] like Figure 2 and Figure 3 As shown, a U-shaped frame 9 is installed on the top of the base 1, and a strip movable plate 19 is provided inside the U-shaped frame 9. The top of the strip movable plate 19 is connected to the U-shaped frame 9 through a hydraulic rod 8, and the hydraulic rod 8 is connected to the controller through a wire. In actual use, the position of the strip movable plate 19 can be adjusted by controlling the extension and retraction of the hydraulic rod 8, which is convenient to adjust.

[0028] like Figure 2 and Figure 3 As shown, a pressure plate 18 is provided at the bottom of the strip movable plate 19, and a plurality of guide rods 20 are vertically installed on the top edge of the pressure plate 18. The tops of the guide rods 20 all slide through the strip movable plate 19, and a pressure sensor 21 is installed on the top of the pressure plate 18. The top of the pressure sensor 21 is in contact with the bottom of the strip movable plate 19. The pressure sensor 21 is connected to the controller through a wire. In actual use, the conveyor belt 5 can move the wooden fire door to the bottom of the pressure plate 18, and then the hydraulic rod 8 can push the pressure plate 18 downward to squeeze the wooden fire door. At the same time, the pressure sensor 21 can detect the pressure on the wooden fire door, so that the pressure on the wooden fire door can be maintained at a preset value.

[0029] It should be noted that each guide rod 20 is provided with a spring 17 on its side, the top of the spring 17 abuts against the strip movable plate 19, and the bottom of the spring 17 abuts against the top of the pressure plate 18. During actual use, the spring 17 can buffer the pressure plate 18 to prevent the hydraulic rod 8 from applying excessive force and damaging the fire door.

[0030] like Figure 1 and Figure 2 As shown, a support platform 11 is installed on the top of the base 1. The support platform 11 is located below the pressure plate 18, and the top of the support platform 11 is flush with the bottom of the accommodating groove 4. When the conveyor belt 5 moves the wooden fire door to the bottom of the pressure plate 18, the bottom of the wooden fire door will contact the top of the support platform 11. The wooden fire door can be supported by the support platform 11, so that the fire door remains stable during inspection.

[0031] It should be noted that if Figure 2 As shown, grooves 22 are provided on both sides of the top of the support platform 11, and a photosensitive sensor 23 is installed inside each groove 22. The photosensitive sensors 23 are connected to the controller in the control box 14 through wires. In actual use, when the conveyor belt 5 moves the fire door to the bottom of the pressure plate 18, the photosensitive sensor 23 on the support platform 11 is blocked by the fire door. At the same time, the photosensitive sensor 23 can transmit the detected signal to the controller, and the controller can complete the positioning of the fire door by synchronously shutting down the drive motor 12, thereby avoiding the position deviation of the fire door and affecting the detection.

[0032] like Figure 1As shown, fixed plates 10 are installed on both sides of the top of the U-shaped frame 9, and one end of the fixed plate 10 is rotatably connected to a protective cover 6. When the protective cover 6 is rotated to be perpendicular to the fixed plate 10, the protective cover 6 covers both sides of the U-shaped frame 9. There is a gap between the bottom of the protective cover 6 and the top of the conveyor belt 5, and there is a gap between the side of the protective cover 6 and the strip movable plate 19 and the edge of the pressure plate 18. In actual use, the openings on both sides of the U-shaped frame 9 can be blocked by the protective cover 6. In this way, when the fire door is damaged during inspection, the flying debris will not injure the staff.

[0033] like Figure 1 As shown, each protective cover 6 is equipped with a mounting base 7 on both sides, and each mounting base 7 is connected to a telescopic mechanism 15 on one side through a hinged seat. The other end of each telescopic mechanism 15 is rotatably connected to the side of the U-shaped frame 9. The telescopic mechanism 15 is an electric push rod, a cylinder or a hydraulic cylinder, and the telescopic mechanism 15 is connected to the controller through a wire. In actual use, the protective cover 6 can be opened through the telescopic mechanism 15, exposing the strip movable plate 19 and the pressure plate 18 to the external environment for easy maintenance.

[0034] Specifically, when the present invention is in use, the staff places the wooden fire door in the corresponding receiving groove 4, and then controls the driving motor 12 to work through the controller. The driving motor 12 drives the conveyor belt 5 to move and moves the fire door to the inside of the U-shaped frame 9. When the fire door moves to the preset position on the support platform 11, the light-sensitive sensor 23 detects the position of the fire door and transmits the signal to the controller. The controller turns off the driving motor 12 and controls the hydraulic rod 8 to extend. The hydraulic rod 8 pushes the strip-shaped moving plate 19 downward so that the bottom of the pressure plate 18 contacts the top of the fire door, squeezing the fire door. At the same time, the pressure sensor 21 is acted upon by the reaction force of the pressure plate 18 and The pressure on the fire door is detected and the detection data is transmitted to the controller. When the fire door is squeezed by the preset pressure for a preset time, the controller controls the hydraulic rod 8 to retract and the pressure plate 18 to separate from the fire door. At the same time, the controller also controls the drive motor 12 to work, and the detected fire door is moved out from the inside of the U-shaped frame 9. At the same time, the fire door to be detected is synchronously moved into the U-shaped frame 9 for detection. The detection efficiency is high, and when re-detecting, the staff can control the telescopic mechanism 15 to retract through the controller, and rotate the protective cover 6 to a vertical position to cover the openings on both sides of the U-shaped frame 9. In this way, during the detection process, debris generated by the damage of the fire door will not splash into the external environment.

[0035] Furthermore, both sides of the strip movable plate 19 are slidably connected to the guide rails fixed on both sides of the inside of the U-shaped frame 9 through sliders, so that the strip movable plate 19 can remain stable, so that the detection results will not be adversely affected during detection.

[0036] Furthermore, if Figure 2As shown, an anti-slip block 16 is installed on the top of each guide rod 20. When the spring 17 is not compressed, the bottom of the anti-slip block 16 contacts the top of the strip movable plate 19. During actual use, the anti-slip block 16 can limit the pressure plate 18 to prevent the pressure plate 18 from detaching from the strip movable plate 19.

[0037] Furthermore, Figure 1 As shown, a plurality of legs 13 are evenly spaced on both sides of the bottom of the base 1 , and the base 1 can be supported by the legs 13 .

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
