Description

Technical Field

[0001] This utility model relates to the field of fire door manufacturing technology, and in particular to a fire door forming device. Background Technology

[0002] Wooden fire doors are made of fire-resistant front and back panels, and fire-resistant filler sandwiched between the front and back panels, glued together.

[0003] Because waiting for the adhesive to dry naturally takes too long, it significantly extends the production cycle of fire doors, increases production costs, and greatly affects production efficiency. Therefore, existing technology uses a hydraulic device as a molding device to press and shape the fire doors. This not only reduces the drying time of the adhesive but also improves the bonding effect after the fire doors are assembled, resulting in significant performance benefits.

[0004] However, in the use of existing technology, during the molding process of fire doors by hydraulic devices, the adhesive between the layers will overflow from the edges of the board under pressure. The overflowing adhesive will come into contact with the pressure-applying components of the hydraulic device and adhere to them. In subsequent work, this will not only cause impurities in the air to stick to the pressure-applying components, but may also cause the pressure-applying components to stick to the fire door panel, affecting the unloading work after the fire door molding is completed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing molding devices where adhesives easily adhere to the pressing components, and to propose a fire door molding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a fire door forming device, including a load-bearing beam, a hydraulic cylinder fixedly connected to the bottom of the load-bearing beam, a connecting frame fixedly connected to the output end of the hydraulic cylinder, a ball seat fixedly connected to the bottom of the connecting frame, a rotating body rotatably installed inside the ball seat, pressure plates connected to the upper and lower sides of the rotating body through a connecting structure, multiple high-pressure nozzles for cleaning are provided on the top of the connecting frame, and a driving structure is provided inside the rotating body to drive the rotating body to rotate inside the ball seat.

[0008] Preferably, the connecting structure includes a slide tube, which is fixedly connected to the end face of the rotating body, and a slider is slidably fitted inside the slide tube, with the pressure plate horizontally fixed to the slider.

[0009] Preferably, the drive structure includes a fixed shaft and a rotating tube. The fixed shaft is horizontally fixed to the ball seat. An installation groove is provided inside the rotating body. One end of the fixed shaft passes through the rotating body and extends into the installation groove. The fixed shaft and the rotating body are rotatably engaged.

[0010] For the fixed shaft located in the mounting slot:

[0011] A bushing is rotatably mounted on a fixed shaft. The bushing is coaxially and fixedly connected to a rotating tube. A rotating seat is rotatably mounted on the bushing. A spur gear is fixedly connected to the outer wall of the rotating seat. A rack is vertically fixed to the slider. The rack matches the spur gear.

[0012] Multiple second pawls are hinged to the rotating seat, and a second ratchet is fixed coaxially to the bushing. The second pawls and the second ratchet are matched.

[0013] For the rotating tube: The rotating tube is fixedly installed on the inner wall of the mounting groove. The rotating tube is sleeved on the fixed shaft, and a spring is provided inside the rotating tube. One end of the spring is fixed to the inner wall of the rotating tube, and the other end is fixed to the fixed shaft.

[0014] Preferably, the inner wall of the mounting groove is provided with a one-way transmission structure to allow the rotating tube to rotate in one direction. The one-way transmission structure includes a first ratchet and a first pawl. The first ratchet is fixedly mounted on the rotating tube, and the first pawl is hinged to the inner wall of the mounting groove. The first pawl matches the first ratchet.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-5 A fire door forming device includes a load-bearing beam 1, a hydraulic cylinder 2 fixedly connected to the bottom of the load-bearing beam 1, a connecting frame 3 fixedly connected to the output end of the hydraulic cylinder 2, a ball seat 4 fixedly connected to the bottom of the connecting frame 3, a rotating body 5 rotatably installed inside the ball seat 4, pressure plates 9 connected to the upper and lower sides of the rotating body 5 through a connecting structure, a plurality of high-pressure nozzles 301 for cleaning are provided on the top of the connecting frame 3, and a driving structure is provided inside the rotating body 5 to drive the rotating body 5 to rotate inside the ball seat 4.

[0028] When pressing the fire door, the fire door is placed flat under the pressure plate 9. Then, the hydraulic cylinder 2 on the load-bearing beam 1 is activated. The hydraulic cylinder 2 drives the connecting frame 3 to move down. The moving of the connecting frame 3 causes the ball seat 4 to move down. The moving of the ball seat 4 causes the rotating body 5 to move down. The pressure plate 9 on the rotating body 5 moves down together. During the downward movement of the pressure plate 9, it comes into contact with the fire door below and applies pressure to the fire door to shape it, ensuring the tightness of the bonding between the layers of the fire door, so as to complete the pressing work.

[0029] For the adhesive adhering to the surface of the pressure plate 9, after the pressure plate 9 has finished molding, the hydraulic cylinder 2 drives the connecting frame 3 to reset. After the connecting frame 3 is reset, the rotating body 5 rotates 180 degrees around a horizontal axis in the ball seat 4. After the rotating body 5 rotates 180 degrees, the pressure plate 9 located below will flip to the top of the rotating body 5. At this time, high-pressure fluid cleaning agent is introduced into the high-pressure nozzle 301 and then high-pressure gas is introduced. The adhesive and impurities adhering to the surface of the pressure plate 9 are cleaned and dried through the high-pressure nozzle 301.

[0030] like Figure 3 and Figure 5 As shown, the connecting structure includes a slide tube 7, which is fixedly connected to the end face of the rotating body 5. A slider 8 is slidably fitted inside the slide tube 7, and a pressure plate 9 is horizontally fixed to the slider 8.

[0031] When the pressure plate 9 is pressing the fire door, after the pressure plate 9 comes into contact with the fire door, the slider 8 will slide and retract a certain distance in the slide tube 7 under the action of the reverse force.

[0032] like Figures 3-9 As shown, the drive structure includes a fixed shaft 11 and a rotating tube 12. The fixed shaft 11 is horizontally fixed to the ball seat 4. An installation groove 6 is provided inside the rotating body 5. One end of the fixed shaft 11 passes through the rotating body 5 and extends into the installation groove 6. The fixed shaft 11 and the rotating body 5 are rotatably engaged.

[0033] like Figure 4 and Figure 6 As shown, for the fixed shaft 11 located in the mounting slot 6:

[0034] A bushing 16 is rotatably mounted on a fixed shaft 11, and a rotating seat 17 is rotatably mounted on the bushing 16. A spur gear 18 is fixedly connected to the outer wall of the rotating seat 17. A rack 10 is vertically fixedly connected to the slider 8. The rack 10 matches the spur gear 18. Multiple second pawls 20 are hinged to the rotating seat 17. A second ratchet 19 is coaxially fixed to the bushing 16. The second pawls 20 match the second ratchet 19.

[0035] like Figure 5 As shown, since the rack 10 is fixedly connected to the slider 8, during the retraction of the slider 8 in the slide tube 7, the slider 8 will cause the rack 10 to move upward. The upward movement of the rack 10 will drive the spur gear 18 to rotate counterclockwise. As can be seen from the figure, when the rack 10 rotates counterclockwise, it will drive the rotating seat 17 to rotate counterclockwise. Due to the presence of the second pawl 20 and the second ratchet 19, when the rotating seat 17 rotates counterclockwise, the rotating seat 17 and the bushing 16 are essentially fixedly connected. Therefore, when the spur gear 18 rotates counterclockwise, it will drive the bushing 16 to rotate counterclockwise.

[0036] like Figure 4 and Figure 6As shown, the bushing 16 is coaxially fixedly connected to the rotating tube 12. The rotating tube 12 is fixedly installed on the inner wall of the mounting groove 6. The rotating tube 12 is sleeved on the fixed shaft 11, and a spring 13 is provided inside the rotating tube 12. One end of the spring 13 is fixedly connected to the inner wall of the rotating tube 12, and the other end is fixedly connected to the fixed shaft 11. A one-way transmission structure is provided on the inner wall of the mounting groove 6 to make the rotating tube 12 rotate in one direction. The one-way transmission structure includes a first ratchet 14 and a first pawl 15. The first ratchet 14 is fixedly installed on the rotating tube 12, and the first pawl 15 is hinged to the inner wall of the mounting groove 6. The first pawl 15 matches the first ratchet 14.

[0037] like Figure 4 and Figure 9 As shown, when the bushing 16 rotates counterclockwise, it will drive the rotating tube 12 to rotate counterclockwise. However, the first pawl 15 and the first ratchet 14 will not limit the counterclockwise rotation of the rotating tube 12. Therefore, the counterclockwise rotation of the rotating tube 12 will only charge the mainspring 13.

[0038] After the mainspring 13 is fully charged, the release of energy from the mainspring 13 requires the rotating tube 12 to rotate clockwise. Due to the presence of the first pawl 15 and the first ratchet 14, the rotating tube 12 is essentially fixedly connected to the inner wall of the mounting groove 6 during this clockwise rotation. That is, the energy released by the mainspring 13 will drive the rotating body 5 to rotate clockwise through the rotating tube 12.

[0039] In this embodiment, the maximum energy that the spring 13 can store can drive the rotating body 5 to rotate 180 degrees. After the rotating body 5 rotates 180 degrees, the positions of the pressure plates 9 located on the upper and lower sides of the rotating body 5 will be swapped, so that the clean pressure plate 9 located above the ball seat 4 will be flipped to the lower side of the ball seat 4, while the pressure plate 9 originally located below will be flipped to the upper side of the ball seat 4.

[0040] Compared with the prior art, the fire door forming device provided in this application uses two pressure plates 9 that can be interchanged to form the fire door. During the continuous forming process, the pressure plates 9 can be cleaned without stopping the machine to prevent the adhesive on the surface of the pressure plates 9 from affecting the forming process.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
