Description

Technical Field

[0001] The present invention relates to the technical field of ceramic fiber blanket extrusion devices, and specifically relates to a multi-layer extrusion device for ceramic fiber blankets. Background Art

[0002] Ceramic fiber blankets are fiber products made of materials such as high-purity alumina and silica, and have characteristics such as high temperature resistance, corrosion resistance, and excellent heat insulation performance. They are widely used in industries, construction, aerospace and other fields. Ceramic fiber blankets are mainly made of fireclay, and are manufactured through processes such as melting, fiberizing, curing in a curing chamber, extrusion, and cutting. When ceramic fiber blankets are produced and processed, an extrusion device is usually used to extrude and form the raw materials of the ceramic fiber blankets.

[0003] However, during the processing of traditional extrusion devices, when the raw materials of ceramic fiber blankets enter the extrusion device, a guide plate usually plays a guiding role for the raw materials of the ceramic fiber blankets. Due to the large frictional force between the raw materials of the ceramic fiber blankets and the guide plate, the guide plate will affect the transportation of the raw materials of the ceramic fiber blankets. Moreover, the guide plate is installed on the conveying table through bolts. When ceramic fiber blankets of different widths need to be processed, it is not convenient to adjust the position of the guide plate, and the ceramic fiber blankets are usually extruded and formed through only one process, resulting in low-quality extruded and formed ceramic fiber blankets.

Detailed implementation manners

[0036] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0037] As Figures 1 - 13As shown in the figure, a multi-layer extrusion device for a ceramic fiber blanket according to the present invention includes a conveying table 1, and a guiding structure 2 is provided on the conveying table 1; a limiting structure 4 is provided on the guiding structure 2; the guiding structure 2 is fixed to the conveying table 1 through the limiting structure 4; a blowing structure 5 is provided on the guiding structure 2; an extrusion structure 3 is provided on the conveying table 1; a compaction structure 6 is provided on the conveying table 1;

[0038] The guiding structure 2 includes an installation frame 201. Two installation frames 201 are connected to the conveying table 1. The right installation frame 201 is fixedly connected to the conveying table 1. The left installation frame 201 is slidably connected to the conveying table 1 through a connecting rod 204. A connecting rod 204 is fixedly connected to the left installation frame 201, and the connecting rod 204 is slidably connected to the conveying table 1. A plurality of rotating rollers 202 are rotatably connected to the installation frame 201, and a first conveyor belt 203 is installed on the rotating rollers 202.

[0039] Specifically, the limiting structure 4 includes a limiting rod 401. The limiting rod 401 is slidably connected to the connecting rod 204, and the limiting rod 401 is engaged with a limiting groove 402 on the conveying table 1. A plurality of limiting grooves 402 matching the limiting rod 401 are provided on the conveying table 1. The limiting rod 401 is fixedly connected to a pressing block 403. The pressing block 403 is slidably connected to the connecting rod 204, and a first return spring 404 is fixedly connected between the pressing block 403 and the connecting rod 204. Two guide wheels 405 are rotatably connected to the connecting rod 204, and the two guide wheels 405 are in rolling connection with the conveying table 1. First, adjust the position of the left mounting frame 201 according to the width of the fiber blanket to be squeezed as needed. The pressing block 403 can be pressed downward. When the pressing block 403 slides downward, the first return spring 404 contracts. At the same time, the pressing block 403 will drive the limiting rod 401 to slide downward, so that the limiting rod 401 slides downward until it is no longer engaged with the limiting groove 402 on the conveying table 1. At this time, the connecting rod 204 can be pushed to drive the left mounting frame 201 to move. When the connecting rod 204 slides relative to the conveying table 1, the guide wheels 405 roll on the conveying table 1, making the sliding of the connecting rod 204 smoother. At the same time, when it slides to a certain position, by releasing the pressing block 403, the limiting rod 401 is engaged with one of the limiting grooves 402 under the action of the first return spring 404. At this time, the adjustment of the position of the left mounting frame 201 is completed. Thus, the rotating roller 202 and the first conveyor belt 203 are driven by the left mounting frame 201 to move, facilitating the rapid adjustment of the position of the first conveyor belt 203 according to the width of the fiber blanket to be squeezed as needed, improving flexibility. At the same time, by the engagement between the limiting rod 401 and the conveying table 1, it is convenient to fix the left mounting frame 201 and the conveying table 1, improving stability. At the same time, when the conveying table 1 conveys the fiber blanket raw material to contact the first conveyor belt 203, when the friction between the raw material and the first conveyor belt 203 is large, the first conveyor belt 203 will move relative to the rotating roller 202, reducing the friction, so as not to affect the conveying of the fiber blanket raw material, and at the same time, it can also play a guiding role.

[0040] Specifically, the air blowing structure 5 includes a mounting block 501. Mounting blocks 501 are fixedly connected to both of the mounting frames 201. A first connecting pipe 502 is installed on the mounting block 501. A plurality of air holes 503 are provided on the first connecting pipe 502. A second connecting pipe 504 is fixedly connected to the first connecting pipe 502. The other end of the second connecting pipe 504 is installed on the air outlet of an air pump 505. The air pump 505 is installed on the conveying table 1. When the first conveyor belt 203 rotates, the air pump 505 can be started. The airflow at the air outlet of the air pump 505 will enter the second connecting pipe 504, then enter the first connecting pipe 502 from the second connecting pipe 504, and finally be blown out from the plurality of air holes 503 on the first connecting pipe 502. The wind blown out from the air holes 503 can blow the fiber blanket raw material on the first conveyor belt 203 towards the middle of the conveying table 1, preventing the fiber blanket raw material from adhering to the first conveyor belt 203.

[0041] Specifically, the extrusion structure 3 includes a mounting frame 301. The mounting frame 301 is slidably connected to the conveying table 1. Two connecting columns 302 are rotatably connected to the mounting frame 301. A second conveyor belt 303 is mounted on the two connecting columns 302. A pressure roller 304 is rotatably connected to the mounting frame 301. Pulley 305 is fixedly connected to both of the two connecting columns 302 and the pressure roller 304. The pulleys 305 are driven by a belt. A first motor 306 is mounted on the mounting frame 301. The output shaft of the first motor 306 is fixedly connected to one of the connecting columns 302. A lead screw 307 is rotatably connected to the conveying table 1. The mounting frame 301 is threadedly connected to the lead screw 307. A handwheel 308 is fixedly connected to the lead screw 307. A guide rod 309 is fixedly connected to the conveying table 1. The mounting frame 301 is slidably connected to the guide rod 309. When the fiber blanket raw material is conveyed to a certain position, by starting the first motor 306, when the output shaft of the first motor 306 rotates, it will drive one of the connecting columns 302 to rotate. When the connecting column 302 rotates, it will drive the pulley 305 to rotate. When the pulley 305 rotates, it will drive the pressure roller 304 and the other connecting column 302 to rotate through the belt. When the two connecting columns 302 rotate, they will drive the second conveyor belt 303 to rotate. The fiber blanket raw material will first be preliminarily extruded and formed by the pressure roller 304, and then conveyed to the lower part of the second conveyor belt 303 through the conveying table 1, and is extruded and formed again by rotating the second conveyor belt 303. Thus, the fiber blanket raw material is subjected to two extrusion processes by the pressure roller 304 and the second conveyor belt 303, further improving the quality of the extruded product of the fiber blanket. At the same time, when the mounting frame 301 needs to be adjusted, by rotating the handwheel 308, when the handwheel 308 rotates, it will drive the lead screw 307 to rotate. When the lead screw 307 rotates, it will threadedly drive the mounting frame 301 to slide downward. When the mounting frame 301 slides downward, the guide rod 309 makes the mounting frame 301 slide more smoothly. Thus, by adjusting the position of the mounting frame 301, the distance between the pressure roller 304, the second conveyor belt 303 and the conveying table 1 can be adjusted, so that fiber blanket products of different thicknesses can be extruded, improving flexibility.

[0042] Specifically, the compaction structure 6 includes a slide bar 602. The slide bar 602 is slidably connected to the mounting frame 301. A pressing plate 601 is fixedly connected to the slide bar 602. A roller 604 is rotatably connected to the slide bar 602. The roller 604 is in rolling connection with a cam 605. The cam 605 is rotatably connected to the mounting frame 301. A second return spring 603 is fixedly connected between the slide bar 602 and the mounting frame 301. A second motor 606 is installed on the mounting frame 301. The output shaft of the second motor 606 is fixedly connected to the cam 605. At the same time, when the fiber blanket raw material is between the pressing roller 304 and the second conveyor belt 303, the second motor 606 can be started. When the output shaft of the second motor 606 rotates, it will drive the cam 605 to rotate. When the cam 605 rotates, it will cause rolling between the roller 604 and the cam 605. By the rolling connection between the roller 604 and the cam 605, the wear is reduced and the service life is improved. When the drop of the cam 605 moves to a certain position, the slide bar 602 will slide downward under the action of the second return spring 603. When the slide bar 602 slides downward, it will cause the pressing plate 601 to continuously pat the preliminarily extruded fiber blanket raw material, and then perform extrusion forming through the second conveyor belt 303. Thus, multiple processes are realized through the cooperation between the pressing plate 601 and the extrusion structure 3, improving the product quality of the fiber blanket. The fiber blanket after pressing and forming can be installed with a cutting component at the right end of the conveying table 1, and then the fiber blanket can be cut according to the required length.

[0043] When the present invention is in use, first, the position of the left mounting frame 201 is adjusted according to the width of the fiber blanket to be extruded as required. The pressing block 403 can be pressed downward. When the pressing block 403 slides downward, the first return spring 404 contracts. At the same time, the pressing block 403 drives the limiting rod 401 to slide downward until the limiting rod 401 no longer engages with the limiting groove 402 on the conveying table 1. At this time, the connecting rod 204 can be pushed to drive the left mounting frame 201 to move. When the connecting rod 204 slides between the conveying table 1, the guide wheel 405 rolls between the conveying table 1, making the sliding of the connecting rod 204 smoother. At the same time, when it slides to a certain position, by releasing the pressing block 403, the limiting rod 401 engages with one of the limiting grooves 402 under the action of the first return spring 404. At this time, the adjustment of the position of the left mounting frame 201 is completed. Thus, the rotating roller 202 and the first conveyor belt 203 are driven by the left mounting frame 201 to move, facilitating the rapid adjustment of the position of the first conveyor belt 203 according to the need to extrude fiber blankets of different widths, improving flexibility. At the same time, by the engagement between the limiting rod 401 and the conveying table 1, it is convenient to fix the left mounting frame 201 and the conveying table 1, improving stability. At the same time, when the conveying table 1 conveys the fiber blanket raw material to contact with the first conveyor belt 203, when the friction between the raw material and the first conveyor belt 203 is large, the first conveyor belt 203 will move relative to the rotating roller 202, reducing the friction, so as not to affect the conveying of the fiber blanket raw material, and at the same time, it can also play a guiding role;

[0044] When the first conveyor belt 203 rotates, the air pump 505 can be started. The air flow at the air outlet of the air pump 505 enters the second connecting pipe 504, then enters the first connecting pipe 502 from the second connecting pipe 504, and finally blows out from the plurality of air holes 503 on the first connecting pipe 502. The wind blown out from the air holes 503 can blow the fiber blanket raw material on the first conveyor belt 203 towards the middle of the conveying table 1, avoiding the adhesion of the fiber blanket raw material to the first conveyor belt 203;

[0045] When the fiber blanket raw material is conveyed to a certain position, by starting the first motor 306, when the output shaft of the first motor 306 rotates, it will drive one of the connecting columns 302 to rotate. When the connecting column 302 rotates, it will drive the pulley 305 to rotate. When the pulley 305 rotates, it will drive the pressing roller 304 and the other connecting column 302 to rotate through the belt. When the two connecting columns 302 rotate, they will drive the second conveyor belt 303 to rotate. The fiber blanket raw material will first be preliminarily extruded and formed by the pressing roller 304, and then conveyed to the lower part of the second conveyor belt 303 through the conveying table 1. It is extruded and formed again by rotating the second conveyor belt 303. Thus, the fiber blanket raw material is subjected to two extrusion processes by the pressing roller 304 and the second conveyor belt 303, further improving the quality of the extruded product of the fiber blanket. At the same time, when it is necessary to adjust the mounting frame 301, by rotating the handwheel 308, when the handwheel 308 rotates, it will drive the lead screw 307 to rotate. When the lead screw 307 rotates, it will drive the mounting frame 301 to slide downward in a threaded manner. When the mounting frame 301 slides downward, the guide rod 309 makes the sliding of the mounting frame 301 smoother. Thus, by adjusting the position of the mounting frame 301, the distance between the pressing roller 304, the second conveyor belt 303 and the conveying table 1 can be adjusted, so that fiber blanket products with different thicknesses can be extruded, improving flexibility;

[0046] At the same time, when the fiber blanket raw material is between the pressing roller 304 and the second conveyor belt 303, by starting the second motor 606, when the output shaft of the second motor 606 rotates, it will drive the cam 605 to rotate. When the cam 605 rotates, rolling will occur between the roller 604 and the cam 605. Through the rolling connection between the roller 604 and the cam 605, wear is reduced and the service life is improved. When the drop position of the cam 605 moves to a certain position, the slide bar 602 will slide downward under the action of the second return spring 603. When the slide bar 602 slides downward, it will cause the pressing plate 601 to continuously pat the preliminarily extruded and formed fiber blanket raw material, and then it is extruded and formed by the second conveyor belt 303. Thus, multiple processes are carried out between the pressing plate 601 and the extrusion structure 3, improving the product quality of the fiber blanket. The pressed fiber blanket can be installed with a cutting component at the right end of the conveying table 1, and then the fiber blanket is cut according to the required length.
