[0036] In use, before the inner wall of the firebrick mold 2 is sprayed, the position of the mold 2 needs to be fixed to prevent shaking during spraying, which may cause errors. According to the embodiment of the application, the double-head rotary rod 3 is electrified and rotated to extrude the internal threads of the thin shaft 26, the thin shaft 26 moves along the inner cavity of the base 1, the push plate 25 is driven to move towards the inside of the mold 2, the plug 24 is attached to the side of the mold 2, and the two push plates 25 gradually clamp the mold 2. The plug 24 is made of rubber and is used to buffer the side of the mold 2, thereby improving the stability of the mold 2.

[0037] When the inner wall of the refractory brick mold 2 needs to be sprayed, first twist off the paint cover and add paint to the paint tank 31, then close the paint cover, start the double-end rotating rod 3, and the double-end rotating rod 3 rotates to extrude the internal thread of the thin shaft 26.

[0038] In combination Figure 6 , Figure 8 , Figure 9The bottom of the pushing box 30 is provided with a uniform assembly, which is used for uniform treatment of paint residue in the mold 2 through lifting and stretching, and the uniform assembly comprises an electric telescopic cylinder 301 installed at the bottom of the pushing box 30, a telescopic piece 302 telescopically connected at the inner cavity of the electric telescopic cylinder 301, a liquid conveying pipe 303 connected at the inner cavity of the telescopic piece 302, a roller 304 fixedly connected to the outer surface of the liquid conveying pipe 303, the roller 304 being made of rubber, and a plurality of wiping strips 305 fixedly connected to the outer surface of the roller 304; two inclined seats 306 are clamped at the bottom of the telescopic piece 302, the inclined seats 306 are located in front of the telescopic piece 302, recessed grooves two are formed in the middle of the inclined seats 306, induction chips 307 are installed on the inner side walls of the two inclined seats 306, an electric telescopic plate 300 is installed at the rear of one of the inclined seats 306, and the inclined seats 306 are internally provided with sliding rails matched with the liquid conveying pipe 303; the telescopic piece 302 is internally provided with a recessed groove 308, the recessed groove 308 is formed in the side surface of the telescopic piece 302 and has a "V" shape; the electric telescopic cylinder 301 is hollow, a sliding groove corresponding to the telescopic piece 302 is formed at the bottom of the electric telescopic cylinder 301, and the plurality of wiping strips 305 are made of rubber; the roller 304 is slidingly connected to the inner wall of the mold 2, and the pushing box 30 is internally provided with a recessed area, so that the roller 304 is hidden in the recessed area, thereby preventing the problem of hindering the overall spraying.

[0039] During work, after spraying, there may be uneven spraying in the mold 2, some places have more paint, and the bottom wall of the mold 2 forms a residue, the paint on one side of the inner 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 pushing box 30 is turned over, the pushing box 30 drives the electric telescopic cylinder 301 to move synchronously. After the electric telescopic cylinder 301 receives the motion electric signal, the signal is fed back to the telescopic piece 302. At this time, the electric telescopic cylinder 301 is powered on to stretch the telescopic piece 302. The telescopic piece 302 drives the roller 304 to move, the roller 304 drives the liquid conveying pipe 303 to move, the liquid conveying pipe 303 directly falls in the middle of the "V" type of the recessed groove 308 and is clamped, the roller 304 is stretched to the inner bottom wall of the mold 2, the roller 304 gradually contacts the residue, and the roller 304 and the wiping strips 305 gradually wipe the inner side wall of the mold 2, thereby wiping the inner side wall of the mold 2 through lifting, improving the degree of uniform spraying, and prolonging the service life of the mold 2. It should be noted that the electric telescopic cylinder 301 and the paint tank 31 are not in the same plane, the liquid conveying pipe 303 moves upward to be recycled to the bottom of the pushing box 30 and is located behind the paint tank 31, and the roller 304 is by default shrunk in the inside of the pushing box 30, so that the spraying solution is not blocked during use.

[0040] Although the uniform processing of the inner bottom wall of the mold 2 can be completed, it is difficult to uniformly wipe the entire surface of the inner bottom wall of the mold 2. Using the embodiment of the application, when the telescopic part 302 is extended, the telescopic part 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 abuts against the inner bottom wall of the mold 2. After the rubber material of the roller 304 abuts against the mold 2, a buffer is generated. The force driving the roller 304 upward drives the roller 304 upward, and the infusion tube 303 moves synchronously. The infusion tube 303 is by default in the middle of the “V”-shaped recessed groove 308. At this time, the infusion tube 303 gradually separates from the middle of the “V”-shaped recessed groove 308 and slides into the inclined seat 306 in front. The recessed groove 308 in front of the telescopic part 302 loses the limiting force, and after the infusion tube 303 separates from the “V”-shaped notch of the recessed groove 308, the infusion tube 303 falls between the two inclined seats 306. The recessed groove two in the inclined seat 306 limits the infusion tube 303. The infusion tube 303 moves downward along the slope surface of the recessed groove two, thereby gradually sliding forward along the inclination angle of the inclined seat 306, wiping the inner bottom wall of the mold 2, and further having the functions of automatic and rapid wiping and automatic movement in the forward and backward directions, so as to enable the roller 304 to quickly and uniformly process the paint liquid in the forward and backward directions of the inner bottom wall.

[0041] When wiping the excess paint liquid, there will be a blind area that cannot be wiped on the back of the inclined seat 306. Therefore, using the embodiment of the application, after the infusion tube 303 enters the inclined seat 306, the infusion tube 303 will contact the sensing chip 307 when continuously moving to the bottom. The sensing chip 307 feeds back the received electrical signal to the electric telescopic plate 300. After the electric telescopic plate 300 is electrified, it gradually elongates to perform secondary wiping treatment on the position of the blind area. It should be noted that after processing is completed, during the reset process, the strong torsional spring between the rotating shaft 28 and the pushing box 30 gradually works. The pushing box 30 drives the paint liquid tank 31 to turn back, the paint liquid tank 31 drives the electric telescopic cylinder 301 to turn back, the electric telescopic cylinder 301 drives the telescopic part 302 to turn back synchronously, the electric telescopic cylinder 301 loses the electrical signal and gradually contracts the telescopic part 302. When turning back, the infusion tube 303 tends to move from bottom to top. The infusion tube 303 moves from the inside of the inclined seat 306 to 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.

[0042] In combination Figure 7The top of the press 5 is provided with a lifting assembly for lifting or lowering the press 5, the top of the press 5 is fixedly connected with a top plate 51, a plurality of guide strips 53 are connected through 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 two is fixedly connected to the top end of the screw rod 52, the output end of the servo motor two is connected with the output end of the screw rod 52, a belt 54 is drivingly connected to the middle of the two screw rods 52, and the screw rod 52 is fixed above the mold 2; the top of the screw rod 52 is provided with a round turntable, the two screw rods 52 are driven to rotate synchronously through the belt 54, and the inside of the top plate 51 is provided with a thread corresponding to the outer surface of the screw rod 52; the inside of the press 5 is matched with the inside of the mold 2 in size, 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 the turning and spraying, and the inside of the water tank 4 contains a water pump.

[0043] When the raw material of the refractory brick needs to be formed, the rotation shaft 28 is often blocked, which affects the subsequent spraying or refractory brick forming process. By using the embodiment of the application, the servo motor two drives the screw rod 52 to move after starting, the screw rod 52 rotates counterclockwise, the screw rod 52 rotates to gradually twist the top plate 51, the texture of the top plate 51 is matched with that of the screw rod 52, the top plate 51 is twisted and rises, the top plate 51 drives the press 5 to gradually move upward, and the distance between the press 5 and the rotation shaft 28 is lengthened. At this time, the servo motor two is turned off to prevent the inside wall of the mold 2 from being sprayed, thereby improving the versatility of use.

[0044] After the spraying process is completed, the refractory brick forming process needs to be performed. The top plate 51 is driven to press downward, and then the top plate 51 drives the press 5 to move synchronously, the press 5 is extruded into the mold 2, and after extrusion forming, heating and cooling are performed to complete the production of the refractory brick. It should be noted that after the spraying is completed, the spraying equipment needs to be reset, the push box 30 is reset to the initial vertical state by the strong torsional spring, and space is left for the downward movement of the press 5, so that the press 5 does not block the inside of the mold 2 when it presses downward.

[0045] Working principle: Before the inside wall of the refractory brick mold 2 is sprayed, the position of the mold 2 needs to be fixed to prevent shaking during spraying, which causes errors.
