Description

Technical Field

[0001] The aluminum silicate fiber refractory brick forming device belongs to the field of brick pressing machine technology. Background Technology

[0002] Refractory bricks are typically produced by pressing. Powdered material is fed into the mold of the brick press, and then the press applies pressure to the mold, thus producing refractory bricks. To ensure consistent production quality, the quality of the powdered material fed into the mold each time must be guaranteed.

[0003] Invention patent CN105690550B discloses an automatic mold for a cylindrical refractory brick press, a fully automatic hydraulic brick press, and a brick pressing process. In this invention, powder material in the product hopper is conveyed to a weighing mechanism via a first conveyor belt. Once the set weight is reached, the weighing mechanism transfers the powder to a second conveyor belt, which then feeds the powder into a distribution trolley. From there, a material distributor delivers the powder into the mold. However, in actual operation, because the first conveyor belt continuously conveys powder to the weighing mechanism, when the powder in the weighing mechanism reaches the braking weight, the first conveyor belt stops conveying powder. However, some powder continues to fall into the weighing mechanism, but the weight of the powder in the weighing mechanism exceeds the set weight. This fully automatic hydraulic brick press cannot accurately control the weight of the powder fed into the mold. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a molding device for aluminosilicate fiber refractory bricks that can ensure the precise quality of powder addition and thus ensure the stable quality of refractory bricks.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: the aluminum silicate fiber refractory brick forming device includes a hopper and a brick press body, as well as a frame, a transfer hopper, a shut-off device and a feeding device. The output port of the hopper is connected to the inlet of the transfer hopper. The transfer hopper is mounted on the frame in a liftable manner. An elastic device is provided between the transfer hopper and the frame. The shut-off device is located at the bottom of the transfer hopper. A transmission device is provided between the shut-off device and the frame, and the shut-off device closes as the transfer hopper rises. The shut-off device is connected to a locking device or the outlet of the transfer hopper is also connected to a slide valve. The feeding device is located between the bottom of the transfer hopper and the brick press body.

[0006] Preferably, the transmission device includes a gear, a fixed rack, a worm, and a worm wheel. The fixed rack is vertically mounted on the frame, and the gear is rotatably mounted on one side of the transfer chamber. The gear meshes with the fixed rack, the worm wheel is connected to the shut-off device, and the worm is fixedly connected to the gear and rotates synchronously. The worm meshes with the worm wheel. The gear moves up and down synchronously with the transfer chamber, thereby driving the shut-off device to open or close via the worm wheel and worm. This allows the shut-off device to automatically adjust the flow rate according to the position of the transfer chamber and to automatically close or open.

[0007] Preferably, the shut-off device includes a mounting plate, sealing plates, and a pushing device. The mounting plate is rotatably mounted on the bottom of the transfer chamber, and a discharge port for material outlet is provided in the center of the mounting plate. Several sealing plates are arranged around the mounting plate, each sealing plate closing the discharge port of the mounting plate. Each sealing plate is slidably connected to the mounting plate. The pushing device is simultaneously connected to each sealing plate and synchronously sets each sealing plate along the radial direction of the mounting plate. The pushing device is connected to a transmission device. The pushing device pushes the sealing plates to move radially along the mounting plate, thereby opening or closing the bottom of the transfer chamber and adjusting the discharge speed of the powder in the transfer chamber.

[0008] Preferably, the pushing device includes a turntable rotatably mounted on the underside of the mounting plate. A transmission device is connected to the turntable. The turntable is annular and has elongated guide holes that correspond one-to-one with the sealing plates. Each sealing plate has a pin that is slidably mounted within its corresponding inclined guide hole. The guide holes, through which the pins push the sealing plates to open or close synchronously, respectively. The transmission device drives the turntable to rotate, which in turn drives the sealing plates to move synchronously, thereby opening or closing the bottom of the transfer compartment.

[0009] Preferably, the elastic device includes a return spring and a transfer frame. The transfer frame is vertically and flexibly mounted on the machine frame. The transfer chamber is fixedly connected to the transfer frame. The return spring is in a compressed state, with its bottom supported on the machine frame and its top supported on the transfer chamber. Several return springs are arranged around the transfer chamber. The return spring pushes the transfer chamber to reset, so that when the weight reduction in the transfer chamber reaches a specified value, the return spring pushes the transfer chamber up a specified distance. This ensures that the weight of the powder delivered from the transfer chamber is accurate and constant, eliminating the need for a weighing mechanism.

[0010] Preferably, the elastic device further includes guide rods and limiting nuts. An outward-facing flange is provided around the top of the transfer chamber. The top of the guide rod is fixedly connected to the outward-facing flange, and the lower end of the guide rod slidably passes through the frame and is threadedly connected to the limiting nut. A return spring is fitted around each guide rod, positioned between the frame and the outward-facing flange. The guide rods guide the transfer chamber, and the compression degree of the return spring can be adjusted by the limiting nut, thereby adjusting the relative position of the transfer chamber and the frame, thus allowing for adjustment of the single-batch discharge volume.

[0011] Preferably, the system also includes a conveyor belt, with the hopper located on one side of the top of the transfer silo, and the conveyor belt positioned between the hopper and the transfer silo. The conveyor belt transports the powder material from the hopper to the transfer silo, thus enabling continuous feeding into the transfer silo.

[0012] Preferably, the feeding device includes a linear module, a carriage, and a sealing device. The carriage is slidably mounted on the frame. The linear module is connected to the carriage and pushes the carriage between the transfer bin and the main body of the brick press. A temporary storage bin is provided on the carriage, and the sealing device is located at the bottom of the temporary storage bin. The sealing device seals the bottom of the temporary storage bin to prevent material leakage. When the linear module pushes the temporary storage bin to directly above the mold of the main body of the brick press, the sealing device opens, allowing all the material to enter the mold.

[0013] Preferably, the sealing device includes a sealing trough and a discharge cylinder. One end of the sealing trough is rotatably mounted on the vehicle body, and the discharge cylinder is positioned between the sealing trough and the vehicle body, pushing the sealing trough to open or close the temporary storage bin. The discharge cylinder pushes the sealing bin to swing, which can both close and open the bottom of the temporary storage bin, allowing the powder to enter the mold.

[0014] Preferably, the sealing device further includes a guide trough and a limiting rod. The guide trough is rotatably mounted on the vehicle body and is located below the closed trough. The limiting rod is located below the closed trough, and the discharge cylinder is located between the guide trough and the vehicle body. When the limiting cylinder pushes the guide trough downward, the closed trough moves downward synchronously under gravity and is positioned on the limiting rod. At this time, the bottom of the temporary storage bin is spaced apart from the closed trough, and the closed trough is spaced apart from the guide trough. The powder in the temporary storage bin enters the guide trough through the closed trough and is then fed into the mold through the guide trough. This ensures that the bottom of the temporary storage bin is reliably sealed and that the powder is smoothly fed into the mold, avoiding the problem of powder being sent to the outside of the mold due to the excessive length of the closed trough when using only the closed trough.

[0015] Compared with the prior art, the beneficial effects of this invention are:

[0016] The initial weight of the material in the transfer hopper of this aluminosilicate fiber refractory brick forming device is greater than the specified weight. When the powder is fed into the feeding device, the weight in the transfer hopper gradually decreases as the powder is fed out. At this time, the transfer hopper gradually rises under the action of the elastic device. Under the action of the transmission device, the shut-off device gradually closes. That is, when the weight of the powder in the transfer hopper decreases by the specified weight, the elastic device pushes the transfer hopper up a specified distance, at which point the shut-off device is completely closed. By precisely controlling the discharge rate, the amount of powder entering the feeding device is controlled, thereby ensuring the accuracy of the weight of the powder entering the feeding device and thus ensuring the stable quality of the produced refractory bricks. When adding material to the transfer hopper, since the shut-off device is closed at this time, the locking device locks the shut-off device or the slide valve closes, thereby ensuring that the bottom of the transfer hopper is closed when powder is added.

[0027] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention necessarily exceeds the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but still fall within the protection scope of this application.

[0028] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the accompanying drawings. Figures 1-9 The present invention will be further described below.

[0029] The aluminum silicate fiber refractory brick forming device includes a hopper 1 and a brick press body 7, as well as a frame 3, a transfer chamber 4, a shut-off device 12, and a feeding device. The output port of the hopper 1 is connected to the inlet of the transfer chamber 4. The transfer chamber 4 is mounted on the frame 3 in a liftable manner. An elastic device is provided between the transfer chamber 4 and the frame 3. The shut-off device 12 is located at the bottom of the transfer chamber 4. A transmission device is provided between the shut-off device 12 and the frame 3, and the shut-off device 12 closes as the transfer chamber 4 rises. The shut-off device 12 is connected to a locking device, or the outlet of the transfer chamber 4 is also connected to a slide valve. The feeding device is located between the bottom of the transfer chamber 4 and the brick press body 7. The initial weight of the material in the transfer chamber 4 of this aluminosilicate fiber refractory brick forming device is greater than the specified weight. When the powder is fed into the feeding device, the weight of the transfer chamber 4 gradually decreases as the powder is fed out. At this time, the transfer chamber 4 gradually rises under the action of the elastic device. Under the action of the transmission device, the stop device 12 gradually closes. That is, when the weight of the powder in the transfer chamber 4 decreases by the specified weight, the elastic device pushes the transfer chamber 4 up a specified distance, and the stop device 12 is completely closed. By precisely controlling the discharge rate, the amount of powder entering the feeding device is controlled, thereby ensuring the accuracy of the weight of the powder entering the feeding device and thus ensuring the stable quality of the produced refractory bricks. When adding material to the transfer chamber 4, since the stop device 12 is closed at this time, the locking device locks the stop device or the slide valve closes, thereby ensuring that the bottom of the transfer chamber 4 is closed when adding powder.

[0030] Specifically, such as Figure 1 As shown: The hopper 1 is located on the upper side of the frame 3, and the transfer chamber 4 is vertically adjustable and located on the right side of the frame 3. A conveyor belt 2 is installed on the top of the frame 3. The input end of the conveyor belt 2 is located below the hopper 1, and the output end of the conveyor belt 2 is located above the transfer chamber 4, thus enabling the material powder in the hopper 1 to be fed into the transfer chamber 4. Since the conveying speed of the conveyor belt 2 is constant, in this embodiment, the amount of material powder in the transfer chamber 4 is controlled by controlling the feeding time of the conveyor belt 2. It is only necessary to ensure that the weight of the material powder in the transfer chamber 4 is greater than the weight of the material powder used in a single operation.

[0031] The feeding device is located at the lower part of the frame 3. The feeding device is mounted on the frame 3. The input end of the feeding device is located directly below the transfer chamber 4, and the output end extends into the brick press body 7, so as to feed the powder into the mold of the brick press body 7 to realize the automatic feeding of the brick press body 7.

[0032] like Figure 2As shown: The elastic device includes a return spring 10 and a transfer frame 8. The transfer frame 8 is slidably mounted on one side of the frame 3, and an outward flange is provided around the top of the transfer compartment 4. The top of the transfer frame 8 is fixedly connected to the outward flange. The return spring 10 is disposed between the transfer compartment 4 and the frame 3. In this embodiment, the return spring 10 is disposed between the outward flange and the frame 3, and the return spring 10 pushes the frame 3 upward through the outward flange. Two return springs 10 are provided at intervals at both ends of the transfer compartment 4, thereby ensuring more stable lifting and lowering of the transfer compartment 4.

[0033] Furthermore, the elastic device also includes a guide rod 9 and a limiting nut 11. The guide rod 9 corresponds to the return spring 10. The guide rod 9 is vertically arranged on the lower side of the outer flange. The upper end of the guide rod 9 is fixedly connected to the outer flange of the transfer chamber 4. The lower end of the guide rod 9 can slide through the frame 3 and is threadedly connected to the limiting nut 11. The return spring 10 is sleeved on the corresponding guide rod 9 and is in a compressed state. The lower end of the return spring 10 is supported on the frame 3 and the upper end is supported on the outer flange of the transfer chamber 4, thereby pushing the transfer chamber 4 to move upward.

[0034] The shut-off device 12 is located at the bottom of the transfer chamber 4. A discharge pipe 15 is located at the bottom of the transfer frame 8. The discharge pipe 15 is vertically arranged and faces the discharge port of the shut-off device 12, so that the powder discharged from the transfer chamber 4 can be sent into the feeding device.

[0035] During operation, the conveyor belt 2 feeds the powder into the transfer bin 4. The weight of the powder in the transfer bin 4 is slightly greater than the weight of the powder to be fed into the mold each time. When the shut-off device 12 is opened, the powder is fed into the feeding device through the discharge pipe 15. As the material decreases, the return spring 10 pushes the transfer bin 4 upward. At this time, due to the action of the transmission device and the shut-off device 12, the shut-off device 12 gradually closes. When the weight of the powder in the transfer bin 4 decreases by a specified amount, the transfer bin 4 rises a specified distance, that is, the shut-off device 12 closes the transfer bin 4. By controlling the discharge amount of the transfer bin 4, the weight of the powder is precisely controlled, ensuring more accurate control of the powder weight.

[0036] That is, mg = kx, where m is the weight reduction of the material in transfer chamber 4, x is the deformation of the return spring 10, k is the elastic coefficient, and g is the acceleration due to gravity. This means that when the material in transfer chamber 4 decreases by a specified weight, the deformation of the return spring 10 is also fixed, and the deformation of the return spring 10 is directly proportional to the weight reduction of the material in transfer chamber 4. The deformation of the return spring 10 is the distance the transfer chamber 4 rises.

[0037] like Figure 2 , 3As shown: The transmission device includes a fixed rack 13, a gear 14, a worm 16, and a worm wheel. A mounting shaft 17 is rotatably mounted on the side of the transfer frame 8 near the machine frame 3. The mounting shaft 17 is horizontally positioned, and both the worm 16 and gear 14 are coaxially mounted on the mounting shaft 17, rotating synchronously with it. The fixed rack 13 is vertically mounted on the machine frame 3 and meshes with the gear 14. The worm wheel is mounted on the stop device 12 and meshes with the worm 16.

[0038] As the material powder is discharged, the transfer bin 4 gradually rises. Simultaneously, the gear 14 rises. Due to the fixed rack 13, the gear 14 gradually rotates during its ascent, thereby gradually closing the shut-off device 12. The worm gear mechanism has a reverse self-locking characteristic, ensuring more stable operation of the shut-off device 12. By adjusting the number of teeth on the gear 14, the relationship between the rising distance of the transfer bin 4 and the rotation angle of the shut-off device 12 can be adjusted. Gears with a smaller number of teeth are preferred for the gear 14 to ensure a wider range of rotation angles for the shut-off device 12.

[0039] like Figures 4-6 As shown: The shut-off device 12 includes a mounting plate 18, a sealing plate 19, and a pushing device, wherein the pushing device includes a turntable 20.

[0040] The mounting plate 18 is annular, and a discharge port is formed in the middle of the mounting plate 18, which is directly opposite the discharge port of the transfer chamber 4. The mounting plate 18 is fixedly connected to the transfer chamber 4. A plurality of guide grooves 1801 are provided at the bottom of the mounting plate 18, arranged radially around the mounting plate 18 and evenly spaced around it. In this embodiment, four guide grooves 1801 are evenly spaced around the mounting plate 18.

[0041] Each sealing plate 19 corresponds to a guide groove 1801. The sealing plates 19 are fan-shaped, and they cooperate to close the material discharge port of the mounting plate 18. Each sealing plate 19 has a mounting part 1901 on its upper side, and each mounting part 1901 is slidably disposed in the guide groove 1801. The guide groove 1801 guides the movement of the sealing plate 19, causing it to move radially along the mounting plate 18, thereby ensuring that each sealing plate 19 reliably closes the material discharge port of the mounting plate 18. Each sealing plate 19 has a pin 1902 on its lower side, which is fixedly connected to the corresponding sealing plate 19 and moves synchronously with it.

[0042] The discharge pipe 15 is located on the lower side of the mounting plate 18, and the discharge pipe 15 is directly opposite the discharge port of the mounting plate 18 to ensure that the powder sent out through the discharge port can fall into the discharge pipe 15.

[0043] The turntable 20 is annular and coaxially mounted on the outside of the discharge pipe 15, allowing it to rotate relative to the discharge pipe 15. The turntable 20 has several guide holes 2001, each corresponding to a sealing plate 19. The pins 1902 of each sealing plate 19 can slidably extend into the corresponding guide hole 2001. The guide holes 2001 are inclined, allowing the sealing plates 19 to move synchronously along the corresponding guide grooves 1801 during the rotation of the turntable 20. A worm gear is fixedly connected to the turntable 20. The turntable 20 can also be used directly as a worm gear.

[0044] When the transfer chamber 4 discharges the powder, the transfer chamber 4 gradually moves upward. The gear 14 rotates and drives the turntable 20 to rotate through the worm gear 16 and worm wheel. Then, through the guide hole 2001 and the pin 1902, the sealing plate 19 is pushed to move inward. When the weight of the released powder reaches the specified weight, the sealing plate 19 just closes the discharge port of the mounting plate 18.

[0045] In this embodiment, the mounting shaft 17 can be connected to a locking device, which can be an electromagnetic brake. This locks the mounting shaft 17 after the transfer chamber 4 moves to the upper side and the sealing plate 19 closes the material inlet of the mounting disc 18. When adding powder to the transfer chamber 4, the gear 14 and the fixed rack 13 prevent the transfer chamber 4 from moving downwards, thus preventing the sealing plate 19 from opening and facilitating control of the powder weight within the transfer chamber 4. Once the powder in the transfer chamber 4 is fully added, the electromagnetic brake releases, causing the transfer chamber 4 to move downwards, at which point the sealing plate 19 opens. Furthermore, the electromagnetic brake is gradually released, causing the transfer chamber 4 to move downwards slowly to avoid impacting the equipment. Alternatively, instead of setting a locking device, a slide gate valve can be installed at the discharge port of the transfer chamber 4. When adding powder into the transfer chamber 4, the slide gate valve is closed. After the powder in the transfer chamber 4 has been added, the slide gate valve is opened. At this time, the powder passes through the slide gate valve and is sent out through the discharge port of the mounting plate 18.

[0046] like Figure 1 As shown: The feeding device includes a linear module, a conveyor frame 5, and a feeding trolley 6. The conveyor frame 5 is mounted on the machine frame 3. Guide rails are installed on both sides of the top of the conveyor frame 5. The two sides of the feeding trolley 6 are slidably connected to the guide rails on the corresponding sides. The linear module is mounted on the conveyor frame 5 and connected to the feeding trolley 6, and pushes the feeding trolley 6 to move between the brick press body 7 and the transfer chamber 4.

[0047] like Figures 7-9As shown: The feeding trolley 6 includes a body 22, a temporary storage bin 21, a material leveling device, and a sealing device. The bottom sides of the body 22 are slidably connected to corresponding guide rails. A linear module is connected to the body 22 and drives the body 22 in reciprocating motion. The temporary storage bin 21 is located on the upper part of the body 22, fixedly connected to the body 22, and moves synchronously with the body 22. The sealing device is installed on the body 22, sealing the bottom of the temporary storage bin 21. The material leveling device is installed on the body 22, located below the sealing device.

[0048] The temporary storage bin 21 can receive the powder sent from the transfer bin 4. The vehicle body 22 drives the temporary storage bin 21 and the material equalization device to move to the top of the mold of the brick press body 7. The sealing device opens, allowing the powder in the temporary storage bin 21 to enter the material equalization device, and then the material equalization device makes the powder enter the mold.

[0049] The temporary storage bin 21 gradually tapers from top to bottom, which facilitates the receiving of powder from the transfer bin 4 and the precise delivery of the powder into the equalization device.

[0050] The sealing device includes a closed material trough 23, a guide material trough 24, a limit rod 26, and a discharge cylinder 25.

[0051] The closed material trough 23 and the guide material trough 24 are located on opposite sides of the temporary storage bin 21. The structure and installation method of the closed material trough 23 are the same as those of the guide material trough 24. In this embodiment, the structure and installation method of the closed material trough 23 are used as an example to describe the structure and installation method of the guide material trough 24 and the closed material trough 23. One end of the closed material trough 23 is provided with a material trough shaft 2302. The closed material trough 23 is rotatably mounted on the vehicle body 22 through the material trough shaft 2302. The opening of the closed material trough 23 faces upward. Both sides of the closed material trough 23 are inclined baffles 2301 that gradually slope outward from bottom to top, so that they can cooperate with the lower part of the temporary storage bin 21, so that the bottom of the closed material trough 23 can press against the bottom of the temporary storage bin 21, thereby sealing the bottom of the temporary storage bin 21 to prevent material powder leakage, and also to prevent material powder from leaking through the sides of the closed material trough 23.

[0052] The guide trough 24 is located below the closed trough 23. The length of the guide trough 24 is less than the length of the closed trough 23. The longer length of the closed trough 23 ensures that the bottom of the temporary storage bin 21 is completely sealed. The shorter length of the guide trough 24 ensures that the powder is smoothly guided into the equalization device. The guide trough 24 can cover the outside of the closed trough 23.

[0053] A limiting rod 26 is located on the lower side of the closed material trough 23. The limiting rod 26 can limit the bottom of the closed material trough 23, keeping the closed material trough 23 in an open state, so as to ensure that the powder in the temporary storage bin 21 can smoothly enter the guide material trough 24. The discharge cylinder 25 is located between the vehicle body 22 and the guide material trough 24. The discharge cylinder 25 is located on the upper side of the guide material trough 24. The discharge cylinder 25 is inclined from top to bottom, gradually approaching the temporary storage bin 21. The discharge cylinder 25 is rotatably mounted on the vehicle body 22. The piston rod of the discharge cylinder 25 is rotatably connected to the guide material trough 24.

[0054] When the bottom of the temporary storage bin 21 is closed, the discharge cylinder 25 retracts. At this time, the free end of the guide chute 24 moves upward and pushes the free end of the sealing chute 23 upward until the sealing chute 23 seals the bottom of the temporary storage bin 21. At this time, the guide chute 24 is stacked on the bottom of the sealing chute 23 and presses the sealing chute 23 tightly against the bottom of the temporary storage bin 21 to ensure reliable sealing of the temporary storage bin 21. When the temporary storage bin 21 discharges material, the discharge cylinder 25 actuates and pushes the free end of the guide chute 24 downward. At this time, the free end of the sealing chute 23 moves downward under the action of gravity until the bottom of the sealing chute 23 is positioned on the limit rod 26. At this time, the sealing chute 23 and the bottom of the temporary storage bin 21 are spaced apart so that the powder in the temporary storage bin 21 can smoothly enter the guide chute 24. The discharge cylinder 25 continues to operate and pushes the free end of the guide trough 24 to continue to move downward. At this time, since the closed trough 23 is limited by the limit rod 26, the closed trough 23 no longer moves. The guide trough 24 moves until its free end is directly opposite the feed inlet of the equalization device. At this time, the discharge cylinder 25 stops operating. The powder enters the guide trough 24 through the closed trough 23 and then enters the equalization device through the guide trough 24.

[0055] The material distribution device includes a contouring groove 27, a feeding motor 30, and a feeding disc 33. The contouring groove 27 is a vertically arranged cylindrical shape, and its cross-sectional shape matches the shape of the mold cavity to allow the powder to smoothly enter the mold cavity. A retaining groove 28 is provided on one side of the top of the contouring groove 27. The retaining groove 28 is located on the side of the contouring groove 27 away from the guide groove 24, and its opening faces the guide groove 24. When the free end of the guide groove 24 moves downward, it extends into the retaining groove 28 to prevent powder from being added to the outside of the contouring groove 27, ensuring that all powder can enter the mold through the contouring groove 27, thereby ensuring more accurate weight of the powder entering the mold.

[0056] An installation sleeve is fixedly installed in the middle of the contour groove 27. The installation sleeve is fixedly connected to the contour groove 27 by a horizontal installation rod. A material feeding shaft 29 is rotatably installed on the installation sleeve. The middle of the material feeding shaft 29 is rotatably connected to the installation sleeve. The upper end of the material feeding shaft 29 extends upward out of the installation sleeve and is connected to a passive synchronous pulley. The bottom of the material feeding shaft 29 extends downward out of the installation sleeve. A material feeding disc 33 is installed at the bottom of the material feeding shaft 29. The material feeding motor 30 is installed on the right side of the vehicle body 22. An active synchronous pulley is installed on the output shaft of the material feeding motor 30. The active synchronous pulley and the passive synchronous pulley are connected by a synchronous belt 31. The material feeding motor 30 drives the material feeding disc 33 to rotate through the synchronous belt 31, thereby evenly distributing the powder entering the mold and spreading the powder throughout the cavity of the mold.

[0057] Furthermore, the synchronous belt 31 and the feeding motor 30 are positioned directly below the guide trough 24, so the powder will not be spilled onto the synchronous belt 31 or the feeding motor 30. In order to ensure stable operation, a protective cover can also be installed on the outside of the synchronous belt 31.

[0058] A guide frame 32 is also provided inside the contour groove 27. The guide frame 32 is coaxially mounted on the feeding shaft 29 and is located above the feeding disc 33. The guide frame 32 is fixedly connected to the feeding shaft 29, while the feeding disc 33 is detachably connected to the guide frame 32. The guide frame 32 gradually increases in size from top to bottom and can rotate synchronously with the feeding shaft 29, so that the powder entering from one side of the contour groove 27 is evenly dispersed into the outer ring of the mold cavity.

[0059] The bottom of the feeding plate 33 is provided with feeding blades 3301. Feeding blades 3301 are arc-shaped with the outer end inclined to the front in the direction of rotation. The guide frame 32 can distribute the powder in the outer ring of the mold cavity. Feeding blades 3301 can push the powder in the outer ring to the middle of the cavity, so that the powder is evenly distributed in the cavity of the mold, thereby ensuring that the powder fills the entire cavity of the mold.

[0060] The working process of this aluminosilicate fiber refractory brick forming device is as follows: In this embodiment, a slide gate valve is installed at the bottom of the transfer chamber 4. When the slide gate valve is closed, the conveyor belt 2 transports the powder material into the transfer chamber 4. As the weight of the transfer chamber 4 gradually increases, the transfer chamber 4 gradually moves downward until the powder material is added. At the same time, the turntable 20 rotates and pushes the sealing plate 19 outward, gradually opening the discharge port of the mounting plate 18. At this time, because the slide gate valve is closed, the powder material will not be sent out. During this process, the gear 14 and the fixed rack 13 remain engaged.

[0061] When the powder in the transfer bin 4 reaches the specified amount, the conveyor belt 2 stops conveying the powder, and the gate valve opens. At this time, the powder in the transfer bin 4 is gradually fed downwards and falls into the temporary storage bin 21 on the lower side. During the downward feeding of the powder in the transfer bin 4, the weight of the transfer bin 4 gradually decreases. The return spring 10 pushes the transfer bin 4 to move upwards, and the fixed rack 13 causes the gear 14 to rotate, which in turn drives the turntable 20 to rotate through the worm gear 16 and worm wheel. The turntable 20 pushes the sealing plate 19 to move inwards through the guide hole 2001, so that the opening of the discharge port of the transfer bin 4 gradually decreases and the discharge speed of the powder gradually slows down until the weight change of the transfer bin 4 reaches the specified value. Since the deformation of the return spring 10 is linearly related to the weight change of the transfer bin 4 under a certain elastic coefficient, the sealing plate 19 just closes the discharge port of the transfer bin 4, ensuring the accurate weight of the powder in the temporary storage bin 21. During this process, the inner end of the sealing plate 19 remains inserted into the feed inlet of the transfer chamber 4. The opening of the feed inlet is adjusted only by how much it extends into the feed inlet. That is, the sealing plate 19 will not be fully opened, ensuring accurate output weight.

[0062] The linear module pushes the vehicle body 22 until the contour groove 27 is directly above the cavity of the mold. At this time, the discharge cylinder 25 actuates, pushing the free end of the guide groove 24 downward. Simultaneously, the free end of the closed groove 23 moves downward until the bottom of the closed groove 23 is positioned on the limit rod 26. Then, the guide groove 24 moves downward a specified distance. The powder in the temporary storage bin 21 enters the contour groove 27 through the closed groove 23 and the guide groove 24.

[0063] The feeding motor 30 drives the feeding shaft 29 to rotate, which in turn drives the guide frame 32 and the feeding disc 33 to rotate synchronously. When the guide frame 32 rotates, it makes the powder evenly enter the outer circle of the cavity of the mold. When the powder fills the cavity, the feeding disc 33 uses the feeding blades 3301 to push the excess powder on the outside of the cavity to the middle of the cavity, so that the powder fills the entire cavity. The linear module drives the carriage 22 to reset. At this time, the main body 7 of the brick press works and completes the pressing of refractory bricks through the mold.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
