DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Combination Figure 1 and Figure 2 As shown, a refractory brick mold inner wall spraying device described in an embodiment of the present invention includes a base 1, a mold 2 is clamped on the top of the base 1, a double-headed rotary rod 3 is rotatably connected to the inner cavity of the base 1, a guide rail is arranged on the upper surface of the base 1, one end of the double-headed rotary rod 3 is externally connected to a servo motor 1, and the output end of the double-headed rotary rod 3 is connected to the output end of the servo motor 1, a water tank 4 is fixedly connected to one of the corners on the top of the base 1, a press 5 is slidably connected to the inside of the mold 2, a flushing pipe 6 is elastically connected to the top of the water tank 4, and the flushing pipe 6 is used to flush the inner wall of the mold 2, a paint spraying assembly is installed on the outer edge of the top of the mold 2, and the paint spraying assembly sprays paint on various parts of the inner wall of the mold 2 by extrusion and flipping, and a paint liquid tank 31 is rotatably connected above the mold 2, and a paint cover is provided on the side of the paint liquid tank 31, and the spray paint liquid can be filled by twisting the paint cover.

[0024] During operation, in the process of spraying the inner wall of the refractory brick mold 2, there are many spraying structures, the operation is inconvenient, and it is easy to disperse more spray liquid. Using the embodiment of the present invention, the use scenario of the equipment is in a refractory brick spraying factory. First, the mold 2 is placed on the top of the base 1, and then the paint cover is twisted, and the spray paint liquid is added into the paint liquid tank 31, and then the servo motor 1 is powered on. The output end of the servo motor 1 is powered on and rotated to drive the double-headed rotary rod 3 to move. The double-headed rotary rod 3 is arranged to penetrate the paint spraying component. When the double-headed rotary rod 3 rotates, it will be squeezed with the paint spraying component, and the paint spraying component is twisted by the double-headed rotary rod 3 As the paint spraying assembly approaches the mold 2 along the guide rail, it is squeezed against the mold 2 and gradually fits against the side of the mold 2 to improve stability. After the paint spraying assembly is rotated and squeezed by the double-headed rotary rod 3, the paint spraying assembly will squeeze the paint liquid stored in the paint liquid tank 31. After squeezing, the paint liquid gradually sprays out. When spraying out, the inner wall of the mold 2 is sprayed. By rotating on the outer edge of the mold 2, the direction and position of the spraying are adjusted to complete the spraying of all surfaces of the inner wall of the mold 2. After the spraying is completed, it is left to stand for a certain period of time and then cooled to complete. The equipment is easy to operate, has relatively few structures, and has the function of rapid spraying.

[0025] After cooling, refractory brick materials are added to the mold 2, and the press 5 is started to move downward to compact the refractory brick materials. After the sintering and cooling processes, it reaches the predetermined shape. It should be noted that squeezing will continue to spray. The reason why squeezing will continue to spray is that it is designed as a continuous spraying mechanism. When the spray paint assembly is squeezed with the mold 2, the air pressure system inside the device will be activated, causing the paint to spray out continuously until it is no longer squeezed. Combination Figures 1 to 5As shown, the paint spraying assembly includes two limit plates 21 installed on both sides of the mold 2, a conveying groove 22 is opened in the middle of the base 1, a blocking block 24 is slidably connected to the side of the mold 2, a pushing plate 25 is fixedly connected to the side of the blocking block 24 away from the mold 2, and the conveying groove 22 is used to introduce wind to the bottom of the pushing plate 25, a thin shaft 26 is transferred to the inner cavity of the base 1, the pushing plate 25 is fixedly connected to the thin shaft 26, and a mounting plate 27 is fixedly connected to the top of the pushing plate 25; a rotating shaft 28 is transferred to the top of the mold 2, an extrusion disk 29 is fixedly connected to the outer surface of the rotating shaft 28, and a push box 30 is fixedly connected to the end of the extrusion disk 29, the rotating shaft 28 passes through the interior of the push box 30, and a strong torsion spring is arranged between the rotating shaft 28 and the push box 30, buckles for transferring the rotating shaft 28 are arranged on both sides of the top of the mold 2, and the push box 3 0 is fixedly connected to the paint liquid tank 31 at the bottom, and paint spray heads 32 are fixedly connected to both sides of the paint liquid tank 31. The paint liquid tank 31 has an induction switch on the outside, and a hydraulic pump is installed inside the paint liquid tank 31. The induction switch is electrically connected to the hydraulic pump. The push box 30 and the paint liquid tank 31 form a "T" shape. The double-headed rotary rod 3 passes through the interior of the thin shaft 26, and the interior of the thin shaft 26 is provided with a texture matching the double-headed rotary rod 3, and the top of the thin shaft 26 is fixedly connected to the push plate 25; it should be noted that the pushing force of the mounting plate 27 is greater than the self-weight of the push box 30, and the mounting plate 27 is in the shape of the number "7". When the mounting plates 27 are brought close, the more protruding part of the top will first hit the push box 30, and the push box 30 is sleeved on the outside of the rotating shaft 28. After the push box 30 is hit, it rotates with the rotating shaft 28 as the rotating axis.

[0026] During operation, before spraying the inner wall of the refractory brick mold 2, the position of the mold 2 needs to be fixed first to prevent shaking during spraying and causing errors. Using the embodiment of the present invention, the double-headed rotary rod 3 is powered on and rotated to squeeze the internal thread of the thin shaft 26. The thin shaft 26 moves along the inner cavity of the base 1. The thin shaft 26 drives the push plate 25 to move. The push plate 25 moves toward the inside of the mold 2. The block 24 is attached to the side of the mold 2. The two push plates 25 gradually clamp the mold 2. The block 24 is made of rubber and is used to buffer the side of the mold 2, thereby improving the stability of the mold 2. When the inner wall of the refractory brick mold 2 needs to be sprayed, first twist open the paint cover and add paint liquid into the paint liquid box 31, then close the paint cover and start the double-headed rotary rod 3. After the double-headed rotary rod 3 is started, it rotates and squeezes the internal thread of the thin shaft 26. The thin shaft 26 slides in the inner cavity of the base 1. The thin shaft 26 drives the push plate 25 and the mounting plate 27 to move. The mounting plate 27 changes its position and moves toward the push box 30. The push box 30 is initially in an upright state. The top of the mounting plate 27 hits the upright push box 30 and moves. The top of the push box 30 is hit and tilted. After tilting, the push box 30 drives the rotating shaft 28 to move. The push box 30 tends to rotate. The extrusion plate 29 and the paint liquid box 31 move synchronously with the push box 30. The push box 30 rotates forty-five degrees. The push box 30 becomes horizontal at this time, and the push box 30 blocks the upper surface of the mold 2 when it is horizontal. The paint liquid box 31 rotates to the middle of the inner wall of the mold 2. The induction switch inside the paint liquid box 31 receives the electrical signal. After the induction switch is activated, the electrical signal is input into the hydraulic pump and the paint spray head. 32, the hydraulic pump inside the paint tank 31 rotates and works, the paint spray head 32 is opened, the hydraulic pump rotates inside the paint tank 31, the hydraulic pump rotates to stir the paint liquid, and the paint liquid is sprayed out through the paint spray head 32. The paint spray head 32 has multiple spray holes, and multiple surfaces of the inner wall are sprayed through the multiple spray holes, so as to achieve the purpose of quickly spraying the inner wall of the mold 2 and reduce unnecessary spraying steps; it should be noted that when the push box 30 becomes horizontal, the multiple spray holes will move to the middle of the inner wall of the mold 2 after rotation, To facilitate uniform spraying around the inner wall; after spraying, the strong torsion spring gradually resets, and the spraying device returns to its initial horizontal position, and the position occupied by the horizontal state is outside the press 5, which will not interfere with the downward stamping of the press 5, and prevent the stamping space from being blocked when the mold is pressed down. Then wait for the spraying solution to cool down, then put in the refractory brick raw material, start the motor to drive the press 5, and extrude the refractory brick raw material from top to bottom, so that the raw material placed in the mold 2 is extruded and formed, thereby completing the processing of the refractory brick.

[0027] Combination Figure 6 , Figure 8 , Fig. 9As shown: a uniform component is installed at the bottom of the push box 30, and the uniform component is used to uniformly treat the paint liquid residue inside the mold 2 by lifting and telescoping. The uniform component includes an electric telescopic cylinder 301 installed at the bottom of the push box 30, and a telescopic member 302 is telescopically connected to the inner cavity of the electric telescopic cylinder 301, and an infusion tube 303 is transferred to the inner cavity of the telescopic member 302. A roller 304 is fixedly connected to the outer surface of the infusion tube 303, and the roller 304 is made of rubber. A plurality of wiping strips 305 are fixedly connected to the outer surface of the roller 304; two inclined seats 306 are clamped at the bottom of the telescopic member 302, and the inclined seat 306 is located directly in front of the telescopic member 302, and a recessed groove 2 is opened in the middle of the inclined seat 306, and the inner side walls of the two inclined seats 306 are An induction chip 307 is installed, and an electric telescopic plate 300 is installed behind one of the tilting seats 306. A sliding track compatible with the infusion tube 303 is arranged inside the tilting seat 306. A recessed groove 308 is opened inside the telescopic part 302. The recessed groove 308 is opened on the side of the telescopic part 302, and the recessed groove 308 is in a "V" shape; the interior of the electric telescopic cylinder 301 is hollow, and a sliding groove corresponding to the telescopic part 302 is opened at the bottom of the electric telescopic cylinder 301, and multiple wiping strips 305 are made of rubber; the roller 304 is slidably connected to the inner wall of the mold 2, and a recessed area is arranged inside the push box 30 so that the roller 304 can be hidden in the recessed area to prevent the problem of hindering comprehensive spraying.

[0028] During operation, after spraying, the inside of the mold 2 will be unevenly sprayed. In some places, more paint liquid is sprayed, and residues are formed on the bottom wall of the mold 2. The paint liquid on one side of the bottom wall of the mold 2 is higher than that on the other side, which is not conducive to the subsequent use of the mold 2. When the push box 30 is turned over, the push box 30 will drive the electric telescopic cylinder 301 to move synchronously. After receiving the electric signal of the movement, the electric telescopic cylinder 301 is fed back to the telescopic member 302. At this time, the electric telescopic cylinder 301 is energized to extend the telescopic member 302. The telescopic member 302 drives the roller 304 to move, and the roller 304 drives the infusion tube 303 to move. The infusion tube 303 directly falls into the recessed groove 3 The "V" shape of 08 is stuck in the middle, the roller 304 extends to the inner bottom wall of the mold 2, the roller 304 gradually contacts the residual part, the roller 304 and the wiping strip 305 gradually wipe the inner wall of the mold 2, and then wipe the inner wall of the mold 2 by lifting and lowering, so as to improve the degree of uniform spraying and improve the service life of the mold 2; it should be noted that the electric telescopic cylinder 301 and the paint liquid box 31 are not on the same plane, when the infusion tube 303 moves upward and is recovered to the bottom of the push box 30, and is located behind the paint liquid box 31, the roller 304 is retracted inside the push box 30 by default, so there will be no situation of blocking the spraying solution when in use; Although the inner bottom wall of the mold 2 can be evenly treated, it is difficult to evenly wipe the entire surface of the inner bottom wall of the mold 2. When the telescopic member 302 is extended, the telescopic member 302 drives the infusion tube 303 to move synchronously. When the infusion tube 303 is about to move to the inner bottom wall of the mold 2, the roller 304 first contacts the inner bottom wall of the mold 2, and the wiping strip 305 rolls and wipes the inner bottom wall of the mold 2. The inner bottom wall of the mold 2 contacts the roller 304, and the roller 304 and the inner bottom wall of the mold 2 move against each other. The rubber material of the roller 304 and the mold 2 will produce a buffer after being abutted. The force of the roller 304 driving upward drives the roller 304 upward, and the infusion tube 303 moves accordingly. The infusion tube 303 defaults to the "V" of the recessed groove 308. The infusion tube 303 is in the middle of the "V" shape, and gradually detaches from the middle of the "V" shape of the recessed groove 308 at this time, and the infusion tube 303 slides to the inclined seat 306 in front. The recessed groove 308 in front of the telescopic member 302 loses its limiting force. After the infusion tube 303 detaches from the "V"-shaped notch of the recessed groove 308, the infusion tube 303 falls between the two inclined seats 306, and the recessed groove 2 in the inclined seat 306 limits it. The infusion tube 303 moves downward along the slope surface of the recessed groove 2, and thus gradually slides forward with the inclination angle of the inclined seat 306, wiping the inner bottom wall of the mold 2, thereby having the function of automatic and rapid wiping and the function of automatic forward and backward movement, so that the roller 304 can quickly and evenly process the paint liquid in the forward and backward directions of the inner bottom wall; When wiping the excess paint liquid, there will be a blind area on the back of the tilt seat 306 that cannot be wiped. Therefore, using the embodiment of the present invention, after the infusion tube 303 enters the tilt seat 306, the infusion tube 303 continues to move to the bottom and contacts the sensor chip 307. The sensor chip 307 feeds back the received electrical signal to the electric telescopic plate 300. After the electric telescopic plate 300 is powered on, it gradually extends, and the position of the blind area is wiped twice. It should be noted that after the processing is completed, during the reset process, the rotating shaft 28 and the push box 3 0, the strong torsion spring gradually works, the push box 30 drives the paint liquid box 31 to flip back, the paint liquid box 31 drives the electric telescopic cylinder 301 to flip, the electric telescopic cylinder 301 drives the telescopic member 302 to flip synchronously, the electric telescopic cylinder 301 loses the electrical signal and gradually shrinks the telescopic member 302. When flipping back, the infusion tube 303 forms a trend of moving from bottom to top, the infusion tube 303 moves from the inside of the tilting seat 306 to the direction of the initial position, and when passing through the recessed groove 308, the infusion tube 303 is embedded into the recessed groove 308 again to form a reset.

[0029] Combination Figure 7As shown: the top of the press 5 has a lifting assembly, which is used to raise or lower the press 5. The top of the press 5 is fixedly connected to a top plate 51, and a plurality of guide strips 53 are connected to the top of the top plate 51. Two screw rods 52 are rotatably connected to the middle of the top of the top plate 51. A servo motor 2 is fixedly connected to the top of the screw 52. The output end of the servo motor 2 is connected to the output end of the screw 52. A belt 54 is connected to the middle of the two screw rods 52. The screw 52 is fixedly connected above the mold 2. A round turntable is provided on the top of the screw 52. The two screws 52 are driven to rotate synchronously through the belt 54. The top of the top plate 51 is provided with a thread corresponding to the outer surface of the screw 52. The size of the inside of the press 5 is adapted to that of the inside of the mold 2. The guide strips 53 extend through the inside of the top plate 51 to the top of the mold 2. The distance between the press 5 and the mold 2 is greater than the distance occupied during flip spraying. The water tank 4 contains a water pump.

[0030] During operation, when the refractory brick raw material needs to be molded, it is often blocked by the rotating shaft 28, resulting in the subsequent spraying or refractory brick molding being affected. Using the embodiment of the present invention, the servo motor 2 is started to drive the screw 52 to move, and the screw 52 rotates counterclockwise. The rotation of the screw 52 gradually twists the top plate 51, and the texture of the top plate 51 and the screw 52 are adapted. The top plate 51 is affected by the twisting and rises upward. The top plate 51 drives the press 5 to gradually move upward, and the distance between the press 5 and the rotating shaft 28 is lengthened. At this time, the servo motor 2 is turned off to prevent obstruction when spraying the inner wall of the mold 2, thereby improving the versatility of use. After the spraying process is completed, when the refractory brick forming processing is required, the top plate 51 is pressed down by driving the screw 52, ​​and then the top plate 51 pushes the press 5 to move synchronously, and the press 5 is squeezed into the mold 2. After extrusion and molding, the refractory brick production is completed after heating and cooling. It should be noted that after the spraying is completed, the spraying equipment needs to be reset first. After the push box 30 is reset to the initial vertical state by the strong torsion spring, space is left for the press 5 to move downward to avoid obstruction when the press 5 presses down the mold 2.

[0031] Working principle: Before spraying the inner wall of the refractory brick mold 2, the position of the mold 2 needs to be fixed first to prevent shaking during spraying and causing errors. Using the embodiment of the present invention, the double-headed rotary rod 3 is powered on and rotated to squeeze the internal thread of the thin shaft 26, and the thin shaft 26 moves. The thin shaft 26 drives the push plate 25 to move, and the push plate 25 moves toward the inside of the mold 2. The block 24 is attached to the side of the mold 2, and the two push plates 25 gradually clamp the mold 2. The block 24 is made of rubber and is used to buffer the side of the mold 2, thereby improving the stability of the mold 2. When the inner wall of the refractory brick mold 2 needs to be sprayed, the double-headed rotating rod 3 rotates and gradually twists the push plate 25 to move. The movement of the push plate 25 drives the thin shaft 26 and the mounting plate 27 to move synchronously. The mounting plate 27 changes its position. The mounting plate 27 hits the push box 30 to move. The push box 30 rotates with the center of the rotating shaft 28 as a reference. The push box 30 rotates, and the rotating shaft 28 rotates at the outer edge of the top of the mold 2. The extrusion plate 29 rotates ninety degrees, and the push box 30 changes from the initial erected state to a flat state. The push box 30 drives the paint liquid The box 31 moves, the paint liquid box 31 vibrates, the induction switch of the paint liquid box 31 is started, the hydraulic pump inside the paint liquid box 31 rotates and works, the hydraulic pump rotates inside the paint liquid box 31, the rotation of the hydraulic pump stirs the paint liquid, and the paint liquid is sprayed out through the paint spray head 32. The paint spray head 32 contains multiple spray holes. The spraying of the inner wall of the mold 2 is completed by different spraying, which reduces unnecessary spraying steps and prevents occupying more space. It should be noted that after the rotating shaft 28 rotates, the strong torsion spring generates a twisting force, and the equipment is reset after twisting.

[0032] When the refractory brick raw material needs to be molded, it is often blocked by the rotating shaft 28, resulting in the subsequent spraying or refractory brick molding being affected. Using the embodiment of the present invention, the servo motor 2 is started to drive the screw 52 to move, and the screw 52 rotates counterclockwise. The rotation of the screw 52 gradually twists the top plate 51, and the texture of the top plate 51 and the screw 52 are adapted. The top plate 51 is affected by the twisting and rises upward. The top plate 51 drives the press 5 to gradually move upward, and the distance between the press 5 and the rotating shaft 28 is lengthened. At this time, the servo motor 2 is turned off to prevent obstacles from occurring when spraying the inner wall of the mold 2, thereby improving the versatility of use. At the same time, after the spraying process is completed, when refractory brick forming processing is required, the top plate 51 can be pressed down by driving the screw 52, ​​and then the top plate 51 pushes the press 5 to move synchronously, and the press 5 squeezes into the mold 2. After extrusion molding, the refractory brick production is completed after heating and cooling.
