Description

Technical Field

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

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. Their function is to block the spread of fire and the diffusion of smoke, and to ensure the safe evacuation of personnel. Fire doors are generally composed of plywood and fire-resistant boards.

[0003] A search revealed a Chinese patent disclosure for a hot pressing device for fireproof boards (authorization announcement number CN201856432U), which includes upper and lower bases, with several support rods fixedly connected between the upper and lower bases. A pressure plate is installed between the support rods through a sliding fit. A hydraulic cylinder is installed on the upper base, with the piston rod of the hydraulic cylinder pressing against the outside of the pressure plate. A heating device is provided on one side of the lower base, and the pressure plate is connected to the heating device through a heat transfer wire. Multiple layers of fireproof boards are placed on the upper surface of the lower base. Although this patented technology can hot press pre-processed multi-layer fireproof boards into shape as needed using a heat-conducting pressure plate.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the hot pressing device does not have a positioning device for the semi-finished fire doors, which will cause the semi-finished fire doors to be misaligned during the handling, gluing and hot pressing process, thus affecting the fire resistance quality of the fire doors. In addition, after the hot pressing process is completed, the hot-pressed fire doors need to be moved to the conveyor, but the above-mentioned device lacks a feeding structure for the fire doors. Utility Model Content

[0006] The technical solution of this utility model is as follows: a fire door hot pressing device includes a base, a working frame fixedly connected to the top of the base, and a sliding groove opened at both ends inside the working frame. A slider b and a slider a are slidably installed inside the sliding groove. A fixed rod is fixedly connected between the two slider bs, and a bidirectional lead screw is rotatably connected between the two slider as. Clamping plates are threaded to both ends of the outer side of the bidirectional lead screw. The clamping plates are slidably connected to the outer side of the fixed rod. A connecting piece is fixedly connected between the slider a and the slider b.

[0007] By adopting the above technical solution, the rotation of the bidirectional screw can drive the two clamping plates to move in opposite directions, thereby achieving the purpose of clamping and positioning the semi-finished fire door with the help of the two clamping plates, so as to reduce the misalignment of the semi-finished fire door during the glue application and hot pressing process.

[0008] In a preferred embodiment, the work frame is provided with a pushing assembly, which includes a servo motor opened inside the work frame.

[0009] By adopting the above technical solution, the piston rod of the cylinder extends to push the slider b to slide inside the servo motor, and then the connecting piece can be used to pull the slider a, thereby moving the hot-pressed fire door onto the conveyor.

[0010] In a preferred embodiment, a monitoring component is provided on the outer side of the base, the monitoring component including a pressure sensor embedded inside the clamping plate, and a controller is fixedly installed on the outer side of the base.

[0011] By adopting the above technical solution, the pressure sensor can monitor the squeezing force of the clamping plate. When the clamping force reaches the preset value, the information will be transmitted to the controller, and the controller will control the drive source at the work frame to shut down.

[0012] In one preferred embodiment, a servo motor is fixedly mounted on the outer side of one of the sliders a, and the output shaft of the servo motor is fixedly connected to a bidirectional lead screw.

[0017] By adopting the above technical solution, the piston rod of the hydraulic cylinder can be extended and retracted to push the upper pressure plate downward, thereby achieving the purpose of heat pressing the fire door.

[0018] In a preferred embodiment, an electric heating plate is fixedly installed on the side of the upper pressure plate that is close to the work frame, and a through groove is provided inside the machine base to cooperate with the work frame.

[0019] By adopting the above technical solution and setting the through groove, the hot-pressed fire door can be pushed onto the conveyor.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4A fire door hot pressing device includes a base 1, a work frame 2 fixedly connected to the top of the base 1, and two sliding grooves 10 opened at both ends inside the work frame 2. Sliding sliders b12 and a11 are slidably installed inside the sliding grooves 10. A fixed rod 6 is fixedly connected between the two sliding sliders b12, and a bidirectional screw 7 is rotatably connected between the two sliding sliders a11. Clamping plates 15 are threaded to both ends of the outer side of the bidirectional screw 7. The clamping plates 15 are slidably connected to the outer side of the fixed rod 6. Connecting parts 14 are fixedly connected between the sliding sliders a11 and b12. Before hot pressing the semi-finished fire door, the operator can place the semi-finished fire door on the work frame 2. By rotating the bidirectional screw 7, the two clamping plates 15 can be driven to move in opposite directions. The two clamping plates 15 can be used to clamp and position the semi-finished fire door, thereby reducing the misalignment of the semi-finished fire door during the gluing and hot pressing process and improving the fire resistance quality of the fire door.

[0030] Specifically, the work frame 2 is equipped with a pushing assembly, which includes a servo motor 9 inside the work frame 2. Cylinders 13 are fixedly installed on the inner wall of each servo motor 9. The piston rod of each cylinder 13 is fixedly connected to a corresponding slider b12. By extending the piston rod of the cylinder 13, the slider b12 can be pushed to slide within the servo motor 9, thereby pulling the slider a11 using the connecting piece 14. This allows the hot-pressed fire door to be transferred to the conveyor 3 without the need for manual handling, improving the loading efficiency of the fire door. A monitoring component is installed on the outer side of the machine base 1 to monitor... The measuring components include a pressure sensor 16 embedded inside the clamping plate 15, and a controller 8 fixedly installed on the outside of the base 1. Through the action of the pressure sensor 16, the squeezing force of the clamping plate 15 can be monitored. When the clamping force reaches the preset value, the information will be transmitted to the controller 8, and the controller 8 will control the drive source at the work frame 2 to shut down, so as to stop the clamping plate 15 from continuing to clamp the fire door, thereby avoiding excessive clamping force and damage to the surface of the fire door. A servo motor 9 is fixedly installed on the outside of one of the sliders a11, and the output shaft of the servo motor 9 is fixedly connected to the bidirectional lead screw 7.

[0031] Specifically, the servo motor 9 is located below the slide 10, the conveyor 3 is fixedly installed on the outside of the base 1, and the hydraulic cylinder 5 is fixedly installed on the top of the base 1. The piston rod of the hydraulic cylinder 5 passes through the base 1 and is fixedly connected to the upper pressure plate 17. By extending and retracting the piston rod of the hydraulic cylinder 5, the upper pressure plate 17 can be pushed downward, thereby achieving the purpose of hot pressing the fire door. The side of the upper pressure plate 17 that is close to the work frame 2 is fixedly installed with an electric heating plate. The inside of the base 1 is provided with a through groove 4 that works with the work frame 2 so as to push the hot-pressed fire door onto the conveyor 3.

[0032] Working principle: First, before the hot-pressing process of the semi-finished fire door, the worker can place the semi-finished fire door on the work rack 2. Then, the controller 8 controls the servo motor 9 to start, and the rotation of the bidirectional lead screw 7 can drive the two clamping plates 15 to move in opposite directions. Thus, the two clamping plates 15 can be used to clamp and position the semi-finished fire door. When the clamping force of the clamping plates 15 reaches the preset value of the pressure sensor 16, the information will be transmitted to the controller 8, and the controller 8 will control the servo motor 9 at the work rack 2 to close. The clamping plate 15 can be closed to stop the continued clamping of the fire door, thereby avoiding excessive clamping force that could damage the surface of the fire door. Then, the hydraulic cylinder 5 can be started to achieve the hot pressing operation of the fire door. Finally, the cylinder 13 can be started. By extending the piston rod of the cylinder 13, the slider b12 can be pushed to slide in the servo motor 9. Then, the slider a11 can be pulled by the connecting piece 14, so that the hot-pressed fire door can be transferred to the conveyor 3 without the need for personnel to move it in the middle, thereby improving the loading efficiency of the fire door.
