Description

Technical Field

[0001] The invention relates to production equipment for Class A fireproof thermal insulation boards. Background Art

[0002] With the gradual improvement of safety awareness, in the process of building design, the fireproof grade of the insulation materials used is generally no longer satisfied with the traditional Class B requirements. More and more buildings use Class A non-combustible insulation materials in the process of design and construction. At present, Class A fireproof insulation materials are roughly divided into pure inorganic types (such as rock wool insulation board / belt, foam glass board, etc.) and organic-inorganic composite types (such as silicon graphene insulation board, inorganic modified polystyrene board, etc.). The rigidity indicators of the material such as compression, tension, bending deformation, and bending load are directly related to the safety after being installed on the wall. In the process of insulation material production, the rigidity of the insulation board is often improved by adding reinforcing mesh / ribs inside the material. However, due to the limitations of processing technology, the reinforcing mesh currently used is a sheet mesh that is manually laid out, which is inefficient, and the position and height of the mesh cannot be controlled, which has a great impact on product quality.

[0052] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0053] Example 1

[0054] like Figure 1 , Figure 2 and Figure 3As shown, the present embodiment discloses a production equipment for Class A fireproof insulation board, which includes: a cloth unit 1, which is used to place the lower mold 200 of the mold and put the raw material composition into the lower mold 200; a pressurizing unit 3, which is located downstream of the cloth unit 1 and is used to apply force on the mold so that the upper mold and the lower mold 200 are tightly abutted and connected; a mesh device 2, which is arranged between the cloth unit 1 and the pressurizing unit 3, and the mesh device 2 includes a conveying component 21, a mesh cutting mechanism 22, a side support 23 and a placement component 24, the conveying component 21 is used to convey the reinforcing net 100 to the side support 23, the mesh cutting mechanism 22 is arranged between the side support 23 and the conveying component 21 and is used to cut the reinforcing net 100 so that the cut reinforcing net 100 is placed on the side support 23, and the placement component 24 is used to place the reinforcing net 100 on the side support 23 into the lower mold 200.

[0055] The lower mold 200 will be placed on the material dispensing unit 1, and the raw material composition will be injected into the lower mold 200, and then the lower mold 200 will be transported to the mesh dispensing device 2. In the mesh dispensing device 2, the conveying component 21 will convey the reinforcing net 100 to the side support 23, and the mesh cutting mechanism 22 will be used to cut the reinforcing net 100. The cut reinforcing net 100 will be placed on the side support 23, and then the reinforcing net 100 on the side support 23 will be placed into the lower mold 200 by the placing component 24. The mesh dispensing device 2 realizes automation instead of the existing manual mesh dispensing; and achieves the effect of precise mesh dispensing, which improves the quality stability of the finished product.

[0056] After the automatic mesh laying operation is realized by the mesh laying device 2, the lower mold 200 will be transported to the pressurizing unit 3, and the pressurizing unit 3 will provide a force on the mold, so that the upper mold and the lower mold 200 are closely matched, and pressure is applied to the raw material composition. The raw material composition will be squeezed in the mold, increasing the density of the product, greatly improving the quality of the product, and expanding the applicability of the product. At the same time, a series of automated production lines such as the material laying unit 1 and the pressurizing unit 3 replace manual operations, reduce the safety hazards and uncontrollable risks of product quality caused by manual operations, further improve production efficiency, and increase output and economic benefits.

[0057] The conveying assembly 21 includes a flattening roller set 211 and a roller propulsion mechanism 212. The flattening roller set 211 is used to wind and place the reinforcing net 100. The roller propulsion mechanism 212 is used to push the reinforcing net 100 on the flattening roller set 211 forward to the side support 23 and straighten and flatten the reinforcing net 100 through the flattening roller set 211. The reinforcing net 100 is wound and placed on the flattening roller set 211, thereby achieving the purpose of using a "roll net" instead of a "sheet net". When in use, the reinforcing net 100 is pushed forward by the roller propulsion mechanism 212, and the flattening roller set 211 will rotate, so that the reinforcing net 100 is straightened and flattened by the flattening roller set 211. By straightening and flattening the reinforcing net 100, the purpose of using a "roll net" instead of a "sheet net" is achieved, which greatly reduces the raw material cost of the reinforcing net 100 and the corresponding transportation cost.

[0058] The placement component 24 is located above the side support 23, and the placement component 24 includes a lifting mechanism 241 and a linkage mechanism 242. The lifting mechanism 241 is connected to the top of the linkage mechanism 242 and is used to drive the linkage mechanism 242 to move up and down. The bottom of the linkage mechanism 242 has a plurality of push rods 243, and the outer peripheral surface of the push rods 243 has a blocking portion 244 protruding outward. The push rods 243 move downward through the reinforcing net 100 and extend into the lower mold 200. The blocking portion 244 abuts against the top surface of the reinforcing net 100 and drives the reinforcing net 100 to move downward into the lower mold 200.

[0059] When placing the reinforcing net 100, the lifting mechanism 241 will drive the linkage mechanism 242 to move downward, so that the several top rods 243 will move downward and pass through the reinforcing net 100, and the outwardly protruding blocking portion 244 will not be able to pass through the reinforcing net 100 and will abut against the top surface of the reinforcing net 100, thereby applying a downward force to the reinforcing net 100, so that the reinforcing net 100 is separated from the side support 23 and moves downward under the downward force, so as to be placed in the lower mold 200 directly below.

[0060] The bottom end of the top rod 243 will move downward and will abut against the bottom surface of the lower mold 200. The blocking parts 244 on the top rods 243 will drive the reinforcing mesh 100 to penetrate into the lower mold 200 and be located inside the raw material composition, thereby limiting the vertical height of the mesh. The position of the reinforcing mesh 100 in the Class A fireproof insulation board is accurately controlled to meet the preset requirements, thereby ensuring the overall structural strength of the Class A fireproof insulation board and improving the stability of the Class A fireproof insulation board.

[0061] In this embodiment, the number of the material distribution unit 1 and the number of the net distribution device 2 are both one. When a layer of reinforcing net 100 is arranged in the A-class fireproof insulation board, the net distribution device 2 can realize the arrangement of a layer of reinforcing net 100 in the A-class fireproof insulation board.

[0062] The mesh-laying device 2 further includes a transmission mechanism 25, the two ends of which are respectively connected to the fabric unit 1 and the mesh-laying device 2, and the transmission mechanism 25 is used to transport the lower mold 200 back and forth between the fabric unit 1 and the position directly below the side support 23. When two layers of reinforcing mesh 100 need to be arranged, one layer of reinforcing mesh 100 can be arranged on the raw material composition of the lower mold 200 through the fabric unit 1 and the mesh-laying device 2 once, and then the lower mold 200 is returned to the fabric unit 1 through the transmission mechanism 25, and the raw material composition is injected on the arranged reinforcing mesh 100 through the fabric unit 1, and then another layer of reinforcing mesh 100 will be arranged when passing through the mesh-laying device 2, thereby realizing the arrangement of two layers of reinforcing mesh 100. When multiple layers of reinforcing mesh 100 need to be arranged, the lower mold 200 can be returned and transported multiple times through the transmission mechanism 25, which is very convenient to use.

[0063] The stopper 244 can be moved up and down on the outer circumference of the top rod 243 to change the distance between the stopper 244 and the bottom end of the top rod 243, and the bottom end of the top rod 243 is against the bottom surface in the lower mold 200. The stopper 244 can be moved up and down on the outer circumference of the top rod 243, so that the distance between the stopper 244 and the bottom end of the top rod 243 can be adjusted, so that the position of the reinforcing net 100 in the lower mold 200 can be adjusted and controlled to meet the preset requirements. At the same time, by adjusting the movement of the control stopper 244, the placement component 24 can accurately set multiple layers of reinforcing nets 100 at different positions in the raw material composition, corresponding to the arrangement requirements of multiple layers of reinforcing nets 100 with different vertical heights, ensuring the overall structural strength of the Class A fireproof insulation board, greatly improving the stability of the Class A fireproof insulation board, and extending its service life.

[0064] The preset position of the reinforcing net 100 can be adjusted by adjusting the position of the stopper 244 on the top rod 243. Of course, the preset position of the reinforcing net 100 can also be adjusted by the lifting mechanism 241. The net-laying device 2 also includes a detection component, which is electrically connected to the lifting mechanism 241. The detection component is arranged on the predetermined moving path of the placement component 24 and is used to detect the placement component 24 to control the linkage mechanism 242 to stop moving downward. The detection component will be used to detect the descending distance of the placement component 24, so as to control the closing of the lifting mechanism 241, so that the descending distance of the reinforcing net 100 is accurately controlled, ensuring that the position of the reinforcing net 100 in the Class A fireproof insulation board meets the preset requirements.

[0065] The material distribution unit 1 may include a vibration spring and a vibration motor, and the lower mold 200 is placed on the vibration spring and the vibration motor, and the vibration spring and the vibration motor can drive the lower mold 200 to vibrate in the horizontal direction when distributing the material. The raw material composition is injected into the cavity on the lower mold 200, and the lower mold 200 is driven to vibrate by the vibration motor and the vibration spring to achieve uniform distribution of the material.

[0067] Among them, the production equipment for Class A fireproof insulation board is used to produce insulation materials containing siliceous materials, calcareous materials and polystyrene particles with a fireproof grade of A. The insulation materials containing siliceous materials, calcareous materials and polystyrene particles with a fireproof grade of A can ensure that under the condition of insulation materials of the same thickness, the strength meets the requirements of relevant product standards and the fireproof performance reaches Class A, without the need for additional composite inorganic plates to enhance its strength and fireproof performance. Preferably, the production equipment for Class A fireproof insulation board is used to produce silicon-graphene insulation materials with a fireproof grade of A.

[0068] The pressurizing unit 3 includes a hoisting upper mold component 31 and a pressing cover mold locking component 32. The lower mold 200 in the mold enters the hoisting upper mold component 31, and the hoisting upper mold component 31 will drive the upper mold to move downward and place it on the lower mold 200. The pressing cover mold locking component 32 is located downstream of the hoisting upper mold component 31. The pressing cover mold locking component 32 will apply a force to press the upper mold and the lower mold 200 against each other, and then the upper mold and the lower mold 200 are connected to each other through automatic locking by the pressing cover mold locking component 32 to maintain the pressure in the mold. Among them, the hoisting upper mold component 31 can be in the form of a hanging arm, and the hanging arm contains a device that can lift the upper mold.

[0069] The production equipment for Class A fireproof insulation board also includes at least one heating device 4, which is located downstream of the pressurizing unit 3 and is used to heat the mold.

The cooling unit 6 is located downstream of the heating device 4 and is used to cool the mold, thereby accelerating the cooling and shaping of the mold, improving the production efficiency of the production equipment for Class A fireproof insulation board, and also improving the output and economic benefits.

[0073] The production equipment for Class A fireproof insulation board also includes a lifting and stacking unit 7, which is arranged between the pressurizing unit 3 and the heating device 4, and is used to stack the molds. The lifting and stacking unit 7 is located upstream of the heating device 4, and the multiple molds that have been transported will be stacked and stacked by the lifting and stacking unit 7, so that several molds after stacking are simultaneously transported to the heating device 4 for heating, which improves the production efficiency of the production equipment for Class A fireproof insulation board, and improves the output and economic benefits. Among them, the number of heating devices 4 can be multiple, and simultaneous heating by multiple heating devices 4 further improves the production efficiency of the production equipment for Class A fireproof insulation board.

[0075] The production equipment for Class A fireproof insulation board also includes a scraping and finishing unit 9, which is placed between the material distribution unit 1 and the pressurizing unit 3, and is used to scrape and finish the raw material composition in the lower mold. The scraping and finishing unit 9 is located downstream of the material distribution unit 1, and is used to scrape and finish the raw material composition in the lower mold 200. The lower mold 200 after injection molding is further scraped and finished by the scraping and finishing unit 9 to ensure the flatness of the raw material composition in the lower mold 200.

[0076] The production equipment for Class A fireproof insulation board also includes a cleaning unit 10, which is located downstream of the demoulding device 5 and is used to remove the residue from the mold.

Of course, in other embodiments, the number of mesh devices 2 and cloth units 1 can be set accordingly according to the number of layers of reinforcing mesh 100.
