Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0027] Figure 1 This is a structural schematic diagram of the automatic grouting system for fire door cores provided in an embodiment of this disclosure. Figure 1 As shown, the automatic grouting system for fire door cores provided in this embodiment includes a main material storage device 1, a cement storage device 2, a weighing device 3, a first transport device 4, a second transport device 5, and a grouting mechanism 6. The main material storage device 1 and the cement storage device 2 are disposed above the weighing device 3, and the first transport device 4 is located between the weighing device 3 and the grouting mechanism 6. The weighing device 3 is configured to weigh the grouting main material discharged from the main material storage device 1 and the cement material discharged from the cement storage device 2.

The grouting mechanism 6 is configured to inject the grouting main material and the cement material into the door skin assembly.

[0028] In the automatic grouting system for fire door cores provided in this disclosure, the first transport device 4 can transport the main grouting material and cement material to the grouting mechanism 6, and the second transport device 5 can transport the door skin assembly to the grouting mechanism 6, so that the grouting mechanism 6 can inject the main grouting material and cement material into the door skin assembly, thereby producing a fire door with an integrated door core. The automatic grouting system for fire door cores provided in this disclosure does not require the use of standard panels for assembly and cutting, which improves the production efficiency of fire doors and can produce door cores with better fire resistance.

[0029] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0030] See Figure 1The automatic grouting system for fire door cores provided in this embodiment includes a main material storage device 1, a cement storage device 2, a weighing device 3, a first transport device 4, a second transport device 5, and a grouting mechanism 6. The main material storage device 1 and the cement storage device 2 are positioned above the weighing device 3, and respectively store grouting main material and cement material. The first transport device 4 is located between the weighing device 3 and the grouting mechanism 6, and is used to transport the materials discharged from the main material storage device 1 and the cement storage device 2 into the grouting mechanism 6. The weighing device 3 is configured to weigh the grouting main material discharged from the main material storage device 1 and the cement material discharged from the cement storage device 2, in order to control the weight of the materials transported to the grouting mechanism 6. The second transport device 5 is used to transport the door skin assembly to the grouting mechanism 6, which is configured to inject the grouting main material and cement material into the door skin assembly, thereby producing a fire door with an integrated door core.

[0031] In some embodiments of this disclosure, such as Figure 1 As shown, the weighing device 3 includes a first conveying mechanism 301 and a second conveying mechanism 302. The first conveying mechanism 301 and the second conveying mechanism 302 are located below the outlets of the main material storage device 1 and the cement storage device 2, respectively. The first conveying mechanism 301 and the second conveying mechanism 302 are each equipped with a weighing sensor. The first conveying mechanism 301 and the second conveying mechanism 302 can weigh the grouting main material and the cement material respectively, so that the grouting main material and the cement material are mixed according to a preset ratio.

[0032] For example, both the first conveying mechanism 301 and the second conveying mechanism 302 are conveyor belts, and the grouting material and cement material can fall onto the first conveying mechanism 301 and the second conveying mechanism 302 respectively, thereby transporting the grouting material and cement material to the first transport device 4.

[0033] In some embodiments of this disclosure, such as Figure 1 As shown, the automatic grouting system for fire door cores also includes a mixing device 7. The mixing device 7 has a funnel structure. The inlet of the mixing device 7 is located below the first conveying mechanism 301 and the second conveying mechanism 302, and the outlet of the mixing device 7 is located above the first conveying device 4. The first conveying device 4 can be a conveyor belt or a screw feeder. The mixing device 7 is used to initially mix the grouting main material and cement material to ensure that the grouting main material and cement material are accurately discharged onto the first conveying device 4, preventing the grouting main material and cement material from scattering.

[0034] Optionally, see Figure 1Both the main material storage device 1 and the cement storage device 2 are funnel structures made of steel plates, and vibrating motors are installed on the outer walls of both devices. The volume of the main material storage device 1 and the cement storage device 2 can be determined according to the output and buffer time of the fire door core. The vibrating motors are used to vibrate the grouting main material and cement material to prevent them from clogging the bottom opening of the funnel structure.

[0035] Figure 2 This is a front view of a portion of the structure of an automatic grouting system for fire door cores provided in an embodiment of this disclosure. In some embodiments of this disclosure, such as... Figure 1-2 As shown, the second transport device 5 includes a suction cup assembly 501, a moving assembly 502, and a conveying assembly 503. The moving assembly 502 is connected to the suction cup assembly 501, and the conveying assembly 503 is disposed below the moving assembly 502 and the grouting mechanism 6. The suction cup assembly 501 is used to pick up the door skin assembly. See details... Figure 2 The moving component 502 uses the suction cup component 501 to grab the door skin component from the unloading point, and then automatically transports the door skin component to the conveying component 503. After the sensor on the conveying component 503 detects the door skin component, the motor starts and the door skin component is transported forward. Simultaneously, the limit lifting action of the door skin grouting station begins. The suction cup component 501 includes a clamping cylinder, an industrial suction cup, and a gripper bracket. The clamping cylinder is a self-locking clamping cylinder with a dead point to prevent the fire door from falling off the suction cup in the event of an electrical power failure. The moving component 502 is a three-axis transport truss, enabling X, Y, and Z axis linkage transport. The moving component 502 uses a gear and rack mechanism for transmission, and has advantages such as compact structure, light weight, high transmission efficiency, good stability, and high reliability.

[0036] In some embodiments of this disclosure, see Figure 1 The grouting mechanism 6 has a funnel structure. One end of the first conveying device 4 is located above the inlet of the grouting mechanism 6, and the other end of the first conveying device 4 is located below the mixing device 7. The conveying assembly 503 is located below the outlet of the grouting mechanism 6. The first conveying device 4 can directly convey the material discharged from the mixing device 7 into the interior of the grouting mechanism 6.

[0037] The moving assembly 502 is equipped with a micro-vibration system for loosening and smoothing the material, ensuring that the grouting material fills the door skin assembly. The moving assembly 502 has multiple rollers arranged side-by-side, driven by chains, which offers high transmission efficiency, accurate transmission ratio, and strong load-bearing capacity, making it suitable for long-distance transmission.

[0038] In some embodiments of this disclosure, such as Figure 1As shown, the automatic grouting system for fire door cores also includes a water injection device 8, which is located above the inlet of the grouting mechanism 6. The water injection device 8 is used to inject water into the grouting mechanism 6. The water injection device 8 can inject an appropriate amount of water into the grouting mechanism 6 by coordinating the set values ​​controlled by the flow sensor and the weighing funnel with the water pump according to the requirements of various material ratios.

In some embodiments of this disclosure, such as... Figure 1 , 3 As shown, the automatic grouting system for fire door cores also includes a mixing device 9, which is located above the inlet of the grouting mechanism 6. The mixing device 9 is configured to mix the grouting material, cement material, and water entering the mixing device 9. The mixing device 9 can fully mix the grouting material, cement material, and water, so that the material of each part of the fire door core is evenly distributed.

[0040] Optionally, the main grouting materials involved in the embodiments of this disclosure include fly ash, refractory clay, and water glass. For example, the composition of the main grouting materials is: 85%–92% fly ash, 4%–15% refractory clay, and 1%–4% water glass.

[0041] In some embodiments of this disclosure, such as Figure 1 As shown, the automatic grouting system for fire door cores also includes a controller 10, which is electrically connected to the main material storage device 1, cement storage device 2, weighing device 3, first conveying device 4, second conveying device 5, and grouting mechanism 6. The controller 10 adopts PLC centralized control to control the pneumatic operation and shutdown of each device in the entire automatic grouting system for fire door cores, safety protection, material batching control selection, delayed start of each stage, and opening and closing of gates.

[0042] In some embodiments of this disclosure, such as Figure 1 As shown, the automatic grouting system for fire door cores also includes a pneumatic controller 11 and a conveying device 12. The conveying device 12 is located at the end of the moving assembly 502 away from the suction cup assembly 501. After the door skin assembly is grouted, the moving assembly 502 transports the door skin assembly to the conveying device 12, which is used to transport the grouted door skin assembly. The pneumatic controller 11 is used to control the pneumatic components in the conveying device 12 and the second transport device 5, such as the suction cup assembly 501.
