Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and more specifically, to an extruder for preparing fireproof building materials. Background Technology

[0002] An extruder for preparing fireproof building materials is a piece of equipment specifically designed for producing fireproof building materials. It uses extrusion molding technology to process raw materials into shapes and is widely used in the production of building materials such as fireproof boards, fireproof pipes, and fireproof strips. This equipment features high efficiency and continuous production.

[0003] In existing technologies, firstly, some raw materials cannot be fully mixed before entering the extruder, which may lead to agglomeration or stratification of the raw materials, thus affecting the quality and performance of the products. The mixing and conveying mechanism is responsible for stably conveying the mixed materials to the extrusion section. Its absence may lead to unstable material supply, thus affecting subsequent extrusion and molding processes. Secondly, some equipment cannot complete the plasticizing and extrusion processes of the materials, which may lead to material accumulation or blockage inside the equipment, affecting production efficiency. Finally, some equipment cannot stop the operation in time when the conveyor shaft or motor is overloaded, which may lead to motor burnout or mechanical damage. Long-term overload operation will increase the wear and tear of the equipment, reduce the service life of the equipment, and increase maintenance costs. Overload may cause component breakage or other malfunctions, threatening the safety of operators. Utility Model Content

[0029] Please see Figures 1-5An extruder for preparing fireproof building materials includes a conveying box 1, a mixing conveying mechanism, an extrusion conveying mechanism, and an overload protection mechanism. The mixing conveying mechanism includes a mixing box 2, a wall groove 3, an open wall 4, a side box 5, a hydraulic cylinder 6, and a push plate 7. The wall groove 3 is disposed on the side wall of the mixing box 2, and the side box 5 is connected to the side wall of the mixing box 2. The hydraulic cylinder 6 is mounted on the side box 5, and the push plate 7 is mounted on one end of the hydraulic cylinder 6. The push plate 7 is slidably guided inside the mixing box 2. The open wall 4 is mounted on one end face of the push plate 7, and the open wall 4 can be sealed and connected with the wall groove 3. The extrusion conveying mechanism includes a conveying extrusion box 8, a conveying motor 9, a conveying shaft 10, conveying extrusion blades 11, and an outlet groove 12. The conveying extrusion box 8 is installed at the bottom end of the mixing box 2. The output end of the conveying motor 9 is connected to the conveying shaft 10 for transmission. One end of the conveying shaft 10 extends into the interior of the conveying extrusion box 8. The conveying extrusion blades 11 are mounted on the conveying shaft 10, and the outlet groove 12 is installed at the bottom of one end of the conveying extrusion box 8.

[0030] In this embodiment, the mixing and conveying mechanism is mainly used to uniformly mix the raw materials in the mixing box 2 and convey the mixed material to the extrusion conveying mechanism. The mixing motor 23 installed on the top of the mixing box 2 drives the output shaft 24 to rotate, and the stirring blade assembly 25 on the output shaft 24 starts to operate, which fully mixes the raw materials in the mixing box 2. The rotation of the stirring blade assembly 25 can make the material form a uniform flow state, avoid material stratification or accumulation, and ensure the mixing quality. After the mixing is completed, the hydraulic cylinder 6 is activated, pushing the push plate 7 installed at its end to slide in the mixing box 2, so that the opening wall 4 separates from the wall groove 3, and the material is extruded. The material is introduced to the next stage. The extrusion conveying mechanism is used to further convey and extrude the mixed material. After the material at the bottom of the mixing box 2 is pushed into the conveying extrusion box 8, the conveying motor 9 starts. Its output end drives the conveying shaft 10 to rotate through the transmission connection. The conveying extrusion blades 11 installed on the conveying shaft 10 start to rotate, pushing the material forward along the inside of the conveying extrusion box 8. The conveying extrusion blades 11 generate extrusion force on the material during rotation, ensuring that the material can flow evenly to the bottom of one end of the conveying extrusion box 8. The material is finally discharged from the outlet groove 12 at one end of the conveying extrusion box 8, completing the extrusion molding process.

[0031] The overload protection mechanism includes an overload protection tube 13, an overload protection rod 14, an insertion groove 15, a movement groove 16, an overload protection spring 17, a transverse frame 18, and a moving block 19. One end of the overload protection rod 14 extends into the interior of the overload protection tube 13. The insertion groove 15 is located on the side wall of the overload protection rod 14. The movement groove 16 is longitudinally slidably located on the side wall of the overload protection tube 13. The overload protection spring 17 is installed in the movement groove 16. One end of the moving block 19 is connected to the overload protection spring 17 and is longitudinally slidably located within the movement groove. The overload protection spring 17 pushes the moving block 19, and the moving block 19 pushes the insertion rod into the insertion groove 15, thereby linking the overload protection tube 13 and the overload protection rod 14 together.

[0032] In this embodiment, the output end of the conveyor motor 9 is connected to the conveyor shaft 10 through the overload protection tube 13. When the load is within the normal range, the overload protection rod 14 is linked with the overload protection tube 13, and the conveyor shaft 10 can operate normally to complete the conveying and extrusion of materials. If the load on the conveyor shaft 10 exceeds the set range due to excessive or hard materials, the overload protection rod 14 will be subjected to excessive resistance. The moving block 19 pushes the overload protection spring 17 in the opposite direction, and the moving block 19 and the extension rod disengage from the extension groove 15 to prevent the conveyor motor 9 from continuing to drive the conveyor shaft 10, thereby cutting off the power transmission and protecting the equipment from damage.

[0033] Please see Figures 1-5 As a supplementary embodiment of an extruder for preparing fireproof building materials, which includes a mixing conveying mechanism, an extrusion conveying mechanism, and an overload protection mechanism: one end of the overload protection pipe 13 is connected to the output end of the conveying motor 9; an mounting plate 20 is installed on the side of the conveying box 1, and the conveying motor 9 is mounted on the mounting plate 20; a connecting plate 21 is installed on one end of the overload protection rod 14, and the connecting plate 21 is connected to one end of the conveying shaft 10; a frame 22 is installed at the bottom of the conveying box 1, and the conveying extrusion box 8 is installed at the top of the frame 22; a mixing motor 23 is installed at the top of the mixing box 2, and an output shaft 24 is installed at the output end of the mixing motor 23, and a stirring blade assembly 25 is installed on the output shaft 24; a connecting leg 26 is installed at the bottom of the mixing box 2, and the connecting leg 26 is fixedly installed to the top of the conveying box 1; an upper support block 27 is fixedly installed inside the moving groove 16, and one end of the overload protection spring 17 is connected to the upper support block 27.

[0034] More specifically, the raw materials for fire-resistant building materials are fed into the mixing chamber 2. The mixing motor 23 starts, driving the stirring blade assembly 25 to operate within the mixing chamber 2, completing the uniform mixing of the materials. After mixing, the hydraulic cylinder 6 starts, and the push plate 7 slides to push the mixed material through the bottom of the mixing chamber 2 into the conveying extrusion chamber 8. The opening wall 4 and the wall groove 3 are sealed together to prevent material leakage. The conveying motor 9 starts, driving the conveying shaft 10 and the conveying extrusion blade 11 to rotate, gradually advancing the material within the conveying extrusion chamber 8, and extruding it through the outlet groove 12 to form the final fire-resistant building material. During the conveying and extrusion process, if the material is too hard or accumulates too much, causing overload, the anti-overload mechanism will automatically cut off the power transmission of the conveying shaft 10 to protect the conveying motor 9 and other components. After the overload is eliminated, the anti-overload mechanism will automatically reset, and the device will continue to operate. The extruded material will be discharged from the outlet groove 12, completing the entire preparation process of the fire-resistant building material.

[0035] In summary, during the use or operation of the overall equipment: When the mixing and conveying mechanism is required, it is mainly used to uniformly mix the raw materials in the mixing box 2 and convey the mixed material to the extrusion conveying mechanism. The mixing motor 23 installed on the top of the mixing box 2 drives the output shaft 24 to rotate, and the stirring blade assembly 25 on the output shaft 24 starts to operate, which fully mixes the raw materials in the mixing box 2. The rotation of the stirring blade assembly 25 can make the material form a uniform flow state, avoid material stratification or accumulation, and ensure the mixing quality. After the mixing is completed, the hydraulic cylinder 6 is started, pushing the push plate 7 installed at its end to slide in the mixing box 2, so that the opening wall 4 separates from the wall groove 3, and introduces the material into the next stage.

[0036] When the extrusion conveyor is in operation, it is used to further convey and extrude the mixed material. After the material at the bottom of the mixing box 2 is pushed into the extrusion box 8, the conveyor motor 9 starts and its output end drives the conveyor shaft 10 to rotate through the transmission connection. The extrusion blades 11 installed on the conveyor shaft 10 start to rotate, pushing the material forward along the inside of the extrusion box 8. The extrusion blades 11 generate extrusion force on the material during rotation, ensuring that the material can flow evenly to the bottom of one end of the extrusion box 8. The material is finally discharged from the outlet groove 12 at one end of the extrusion box 8, completing the extrusion process.

[0037] When the overload protection mechanism is required, the output end of the conveyor motor 9 is connected to the conveyor shaft 10 through the overload protection pipe 13. When the load is within the normal range, the overload protection rod 14 is linked with the overload protection pipe 13, and the conveyor shaft 10 can operate normally to complete the material conveying and extrusion. If the load on the conveyor shaft 10 exceeds the set range due to excessive or hard material, the overload protection rod 14 will be subjected to excessive resistance. The moving block 19 pushes the overload protection spring 17 in the opposite direction, and the moving block 19 and the extension rod disengage from the extension groove 15 to prevent the conveyor motor 9 from continuing to drive the conveyor shaft 10, thereby cutting off the power transmission and protecting the equipment from damage.

[0038] The raw materials for fireproof building materials are fed into the mixing chamber 2. The mixing motor 23 starts, driving the stirring blade assembly 25 to rotate within the mixing chamber 2, completing the uniform mixing of the materials. After mixing, the hydraulic cylinder 6 starts, and the push plate 7 slides to push the mixed material through the bottom of the mixing chamber 2 into the conveying extrusion chamber 8. The opening wall 4 and the wall groove 3 are sealed together to prevent material leakage. The conveying motor 9 starts, driving the conveying shaft 10 and the conveying extrusion blade 11 to rotate, gradually pushing the material into the conveying extrusion chamber 8, and extruding it through the outlet groove 12 to form the final fireproof building material. During the conveying and extrusion process, if the material is too hard or accumulates too much, causing overload, the overload prevention mechanism will automatically cut off the power transmission of the conveying shaft 10 to protect the conveying motor 9 and other components. After the overload is eliminated, the overload prevention mechanism will automatically reset, and the device will continue to operate. The extruded material will be discharged from the outlet groove 12, completing the entire preparation process of the fireproof building material.

For all the fixed connections mentioned above, welding is preferred.
