Description

Technical Field

[0001] This invention relates to the technical field of cast iron furnace frame spraying, but is not limited to, the field of cast iron furnace frame spraying, and particularly to a spraying equipment for the production and processing of enamel cast iron furnace frames. Background Technology

[0002] During the production and processing of cast iron furnace frames, it is necessary to spray enamel glaze onto their surface. This is mainly because spraying enamel glaze can provide long-term corrosion protection. Since enamel has the characteristics of acid resistance, alkali resistance, and high temperature resistance, it can effectively resist corrosion and extend the service life of the furnace frame. Moreover, the surface of cast iron furnace frames is generally relatively rough, which makes it easy to accumulate dust and scale, affecting the appearance and cleanliness. Spraying enamel glaze can form a smooth and solid surface, preventing the adhesion of iron filings, dust and other debris, and facilitating cleaning and maintenance.

[0003] Patent publication number CN 113695116 A discloses a high-efficiency spraying processing device suitable for furnace frames. Under the action of the adjustment mechanism, the height of the hopper, the material pipe and the spraying chamber below can be adjusted to meet the spraying purpose of furnace frames of different thicknesses. By setting a clamping mechanism, it can meet the clamping purpose of furnace frames of different sizes, which is highly practical. Under the action of the drive motor, it can achieve uniformity of furnace frame spraying and has a good working effect.

[0004] The aforementioned patent has the following defects:

[0005] Once the cast iron furnace frame is clamped, its position is fixed, and the spraying equipment can only spray one side of it. After one side is finished, the cast iron furnace frame needs to be flipped over and repositioned before the other side can be sprayed. This means that the front and back sides of the cast iron furnace frame cannot be sprayed continuously.

[0006] After the cast iron furnace frame is fixed, its front and back surfaces are perpendicular to the spraying direction. The sprayed enamel glaze falls directly onto the cast iron furnace frame. The rotation of the cast iron furnace frame by the drive motor ensures that only the front and back surfaces are effectively sprayed. However, the inner and outer ring walls of the cast iron furnace frame are parallel to the spraying direction. Although the sprayed enamel glaze moves downward irregularly, allowing the inner and outer ring walls of the cast iron furnace frame to be sprayed with enamel glaze, the sprayed enamel glaze is unstable and uneven. Summary of the Invention

[0007] In view of the problem that the front and back surfaces of cast iron furnace frames, as well as their inner and outer ring surfaces, cannot be continuously and uninterruptedly sprayed in the existing technology, a spraying equipment for the production and processing of enamel cast iron furnace frames is proposed.

[0008] One aspect of this application provides a spraying device for the production and processing of enamel cast iron furnace frames, the purpose of which is to achieve continuous and uninterrupted uniform spraying of the front and back surfaces of the cast iron furnace frame, as well as its inner and outer ring walls.

[0009] The technical solution of the present invention is: a spraying equipment for the production and processing of enamel cast iron furnace racks, including a table, a spraying rack set on the table, and also including a material feeding unit, a spraying unit and a rotating unit;

[0010] The material placement unit is mounted on the spraying frame and is used to support and rotate the cast iron furnace frame;

[0011] The material feeding unit includes: a driving component, which is mounted on the spraying frame and is used to drive the cast iron furnace frame to move and provide power for the rotation of the cast iron furnace frame;

[0012] The storage component, mounted on the drive component, is used to support the cast iron furnace frame;

[0013] The storage component includes a U-shaped frame mounted on the drive component, a Z-shaped rod mounted inside the U-shaped frame, an L-shaped rod at one end of the Z-shaped rod, a cylindrical tube at the bottom of the L-shaped rod, a concave disc at the bottom of the cylindrical tube, a hydraulic cylinder mounted inside the cylindrical tube, a movable disc at the output end of the hydraulic cylinder, the movable disc sliding within the concave disc, and four hinge rods mounted on the movable disc. A support rod is mounted at the end of each hinge rod away from the movable disc, and the support rod movably passes through the concave disc.

[0014] A flipping component, mounted on the storage component, is used to rotate the cast iron furnace frame.

[0015] The spraying unit is installed on the material feeding unit and is used to spray enamel glaze onto the surface of the cast iron furnace frame on the material feeding unit.

[0016] The rotating unit is mounted on the material feeding unit and is used to drive the cast iron furnace frame to rotate while moving.

[0017] Using the above technical solution, the cast iron furnace frame is placed outside the concave disc of the placement component. The hydraulic cylinder extends and drives the moving disc to move down the concave disc. The downward movement of the concave disc drives the hinge rod to rotate and drives the support rod to move closer to the inner ring wall of the cast iron furnace frame. When the support rod and the inner ring wall of the cast iron furnace frame abut against each other, the cast iron furnace frame is supported by four support rods.

[0018] Furthermore, the driving component includes a servo motor mounted on the spray frame, a lead screw mounted on the output end of the servo motor, a nut mounted on the lead screw, a limiting slider mounted on the nut, and a limiting groove mounted on the inner side wall of the spray frame, wherein the limiting slider is slidably connected in the limiting groove.

[0019] Using the above technical solution, the servo motor is started to drive the lead screw to rotate, which in turn drives the nut to move. The movement of the nut causes the limit slider on it to move in the limit groove, which in turn drives the U-shaped frame on the limit slider to move. When the U-shaped frame moves, it drives the cast iron furnace frame in the storage component to move accordingly.

[0020] Furthermore, the flipping component includes a guide groove disposed on the spraying rack. The guide groove includes three sets of horizontal grooves and two sets of inclined grooves. The heights of the three sets of horizontal grooves from the table surface are different. The vertical distance between the uppermost horizontal groove and the middle horizontal groove is less than the vertical distance between the middle horizontal groove and the lowermost horizontal groove. The two sets of inclined grooves are used to connect adjacent horizontal grooves. A roller is disposed at the other end of the Z-shaped rod and is slidably connected in the guide groove.

[0021] Using the above technical solution, when the roller at one end of the Z-shaped rod moves from one set of horizontal grooves to another set of horizontal grooves, the Z-shaped rod will pass through the inclined groove between adjacent horizontal grooves. The rotation of the Z-shaped rod through the inclined groove will cause the placement component and the cast iron furnace frame inside it to rotate, thereby changing the coating surface of the cast iron furnace frame. After the Z-shaped rod moves from the uppermost horizontal groove to the middle horizontal groove, it can coat the inner ring wall and outer ring surface of the cast iron furnace frame. After the Z-shaped rod moves from the middle horizontal groove to the lowermost horizontal groove, it can coat the bottom surface of the cast iron furnace frame.

[0022] Furthermore, the spraying unit includes: a spraying component, disposed above the placement component, for spraying enamel glaze onto the surface of the cast iron furnace frame;

[0023] The spraying component includes a spraying device mounted on a table, a guide hose mounted on the spraying device, a guide tube mounted on the guide hose, a slot on the spraying frame for the guide tube to slide, a storage box mounted at the end of the guide tube, and multiple nozzles mounted at the bottom of the storage box.

[0024] A pushing component, located above the spraying component, is used to push the spray head to move as the cast iron furnace frame rotates.

[0025] Using the above technical solution, during the movement of the cast iron furnace frame, the spray nozzle on the spraying device will continuously spray the cast iron furnace frame. After the cast iron furnace frame is flipped, its position will also change. The pushing component will drive the storage box and the spray nozzle to move, changing the position of the spray nozzle so that the spray nozzle is moved directly above the cast iron furnace frame.

[0026] Furthermore, the pushing component includes a guide plate disposed outside the guide tube, a rectangular groove disposed on the top of the U-shaped frame, the guide plate being slidably fitted within the rectangular groove, guide grooves disposed on the two side walls of the rectangular groove, guide blocks disposed on both sides of the guide plate, the guide blocks being slidably fitted within the corresponding guide grooves, a cylindrical block disposed on the guide plate, a pushing plate disposed on the top of the U-shaped frame, a pushing groove disposed within the pushing plate, the pushing groove being inclined, the cylindrical block being slidably fitted within the pushing groove, a limiting U-shaped clamping plate disposed on the top of the U-shaped frame, a limiting groove disposed on the top of the pushing plate, the limiting U-shaped clamping plate being slidably fitted within the limiting groove, and a connecting assembly disposed on the pushing component. When the flipping component is working, the pushing component is driven to work through the connecting assembly. The connecting assembly includes a rotating rod disposed on the pushing plate, a moving rod disposed at one end of the rotating rod, a guide plate disposed on the inner wall of the U-shaped frame, the moving rod being movably inserted through the U-shaped frame and the guide plate, a connecting rod disposed at the bottom of the moving rod, and a toggle rod disposed at one end of the connecting rod, the other end of the toggle rod being fixed to the outer side of the Z-shaped rod.

[0027] Using the above technical solution, the rotation of the Z-shaped rod as it moves from one horizontal slot to another will cause the actuating rod to rotate. When the actuating rod rotates, it causes the connecting rod to rotate. When the connecting rod rotates, it causes the moving rod to move upward, which in turn causes the rotating rod to rotate. When the rotating rod rotates, it causes the pushing plate to move. When the pushing plate moves, it causes the cylindrical block to slide in the pushing slot, thereby moving the nozzle to directly above the cast iron furnace frame.

[0028] Furthermore, the rotating unit includes: a self-rotating component, disposed above the placement component, for driving the cast iron furnace frame to rotate;

[0029] The self-rotating component includes a first rotating shaft mounted on a cylindrical tube, which movably passes through an L-shaped plate; a bevel gear mounted at the end of the first rotating shaft; a second rotating shaft mounted within a U-shaped frame; an end face gear mounted at one end of the second rotating shaft, with the bevel gear meshing with the end face gear; a gear mounted at the other end of the second rotating shaft, with the second rotating shaft and the gear rotatably connected by a first bearing; and a single-sided toothed groove mounted within a spray frame, where the gear rolls and meshes with the single-sided toothed groove.

[0030] The separation component, located on the rotating component, is used to separate the synchronous rotation between the end face gear and the gear.

[0031] Using the above technical solution, when the drive component moves the U-shaped frame, the U-shaped frame will move the second rotating shaft. When the second rotating shaft moves, it will cause the gear at one end to roll in the single-sided tooth groove, so that the gear will rotate when it moves. The rotation of the gear will drive the second rotating shaft and the end face toothed disc to rotate. When the end face toothed disc rotates, it will drive the bevel gear, which in turn will drive the cylindrical cylinder to rotate, so that the cast iron furnace frame will rotate around the cylindrical cylinder as the axis.

[0032] Furthermore, the separating component includes a plurality of triangular teeth evenly and equidistantly arranged in a ring on the end face of the gear, an annular sleeve disposed outside the second rotating shaft, a plurality of triangular grooves evenly and equidistantly arranged in a ring on the end face of the annular sleeve, wherein the triangular teeth and the triangular grooves mesh with each other, a pressure plate disposed outside the annular sleeve, wherein the annular sleeve and the pressure plate are rotatably connected by a second bearing, two sets of extrusion plates disposed inside the spray frame, wherein the positions of the two sets of extrusion plates correspond to the positions of the inclined grooves in the guide groove, four protrusions disposed inside the annular sleeve, four slots disposed outside the second rotating shaft, wherein the protrusions slide into the corresponding slots, a guide rod disposed inside the slots, wherein the guide rod passes through the protrusions and slides within the protrusions, and an elastic element disposed outside the guide rod, wherein the two ends of the elastic element abut against the protrusions and the inner walls of the slots, respectively.

[0033] Using the above technical solution, the movement of the second rotating shaft will cause the annular sleeve to move accordingly. Before the Z-shaped rod moves into the inclined groove of the guide groove (before the Z-shaped rod drives the cast iron furnace frame to rotate), the pressure plate is squeezed by the extrusion plate, causing the pressure plate to drive the annular sleeve to move away from the gear. When the triangular teeth on the gear and the triangular groove on the annular sleeve separate, the cast iron furnace frame drives the bevel gear to rotate when it rotates. The rotation of the bevel gear drives the end face gear to rotate. When the second rotating shaft moves, it will continue to drive the gear to rotate. At this time, the gear rotation and the end face gear rotate independently and are not constrained by each other. When the cast iron furnace frame has completed the rotation, when the extrusion plate no longer squeezes the pressure plate, the elastic force of the elastic element drives the annular sleeve and the pressure plate to move. At this time, the triangular groove on the annular sleeve and the triangular teeth on the gear mesh. That is, when the second rotating shaft continues to move, the rotation of the gear will drive the second rotating shaft to rotate, which in turn drives the end face gear to rotate, thereby driving the bevel gear and the cast iron furnace frame to rotate.

[0034] This application also provides a method for using a spraying equipment for the production and processing of enamel cast iron furnace frames, including the following steps:

[0035] When the roller rolls from the uppermost horizontal groove in the guide groove to the middle horizontal groove, the Z-shaped rod rotates 80°. The Z-shaped rod drives the L-shaped rod to rotate and the cast iron furnace frame to rotate 80°. At this time, the spraying component sprays the inner ring wall and outer ring surface of the cast iron furnace frame. When the Z-shaped rod continues to move, after the roller rolls from the middle horizontal groove in the guide groove to the lowermost horizontal groove, the Z-shaped rod rotates 100°. The Z-shaped rod drives the L-shaped rod and the cast iron furnace frame to rotate 100°. The spraying component sprays enamel glaze onto the bottom surface of the cast iron furnace frame.

[0036] Using the above technical solution, when the Z-shaped rod moves in the three sets of horizontal grooves of the guide groove, it drives the L-shaped rod to rotate, thereby causing the cast iron furnace frame to flip, so that the front and back of the cast iron furnace frame, as well as its inner and outer ring walls, can be sprayed.

[0037] Furthermore, the Z-shaped rod drives the nozzle to move during both rotations. When the cast iron furnace frame rotates 80°, the position of the cast iron furnace frame changes, and the nozzle will move to the top of the rotated cast iron furnace frame. After the cast iron furnace frame continues to rotate 100°, the nozzle will also move to the top of the cast iron furnace frame.

[0038] Using the above technical solution, after one side of the cast iron furnace frame is coated, it will automatically flip over. The position of the cast iron furnace frame changes after flipping, and the position of the spray nozzle will also change after the cast iron furnace frame flips over. The spray nozzle will always move to the top of the cast iron furnace frame after flipping over, so that the spray nozzle can effectively coat the cast iron furnace frame.

[0039] Furthermore, as the U-shaped frame moves, it drives the cast iron furnace frame to rotate. Before the Z-shaped rod drives the cast iron furnace frame to flip, the pressure plate on the annular sleeve is squeezed by the extrusion plate, causing the pressure plate to drive the annular sleeve to move away from the gear. When the triangular teeth on the gear and the triangular groove on the annular sleeve separate, the cast iron furnace frame drives the bevel gear to flip when it flips. The flipping of the bevel gear drives the end face gear to rotate, and the second rotating shaft continues to drive the gear to rotate when it moves. At this time, the gear rotation and the end face gear rotate independently and are not constrained by each other. When the cast iron furnace frame has finished flipping, when the extrusion plate no longer squeezes the pressure plate, the elastic force of the elastic element drives the annular sleeve and the pressure plate to move. At this time, the triangular groove on the annular sleeve and the triangular teeth on the gear mesh. That is, when the second rotating shaft continues to move, the rotation of the gear will drive the second rotating shaft to rotate, which in turn drives the end face gear to rotate, thereby driving the bevel gear and the cast iron furnace frame to rotate.

[0040] Using the above technical solution, during the movement of the cast iron furnace frame, the bevel gear is driven to rotate by the end face toothed disc, thereby driving the cast iron furnace frame to rotate. Before the cast iron furnace frame needs to be flipped, the ring sleeve and the gear are separated, so that the gear rotates and the end face toothed disc rotates independently, without being constrained by each other, thus avoiding the phenomenon of tooth jamming when the cast iron furnace frame is flipped.

[0041] The beneficial effects of this invention are:

[0042] When the U-shaped frame moves, the Z-shaped rod moves within three sets of horizontal slots. When the roller rolls from the uppermost horizontal slot in the guide slot to the middle horizontal slot, the Z-shaped rod rotates the cast iron furnace frame 80°. At this point, the inner and outer ring walls of the cast iron furnace frame can be sprayed. As the Z-shaped rod continues to move, the roller rolls from the middle horizontal slot in the guide slot to the lowermost horizontal slot. At this point, the Z-shaped rod rotates the cast iron furnace frame 100°. At this point, the bottom surface of the cast iron furnace frame can be sprayed. In other words, the front and back of the cast iron furnace frame, as well as its inner and outer ring walls, can be continuously sprayed.

[0043] When the cast iron furnace frame is rotated for the first time, its position changes, and at the same time, the position of the nozzles also changes. The nozzles will move directly above the cast iron furnace frame as it rotates. When the cast iron furnace frame is rotated again, the nozzles will also move accordingly, moving directly above the cast iron furnace frame once more, ensuring that the nozzles are always directly above the cast iron furnace frame and guaranteeing effective coverage.

[0044] As the cast iron furnace frame moves, it drives the second rotating shaft to rotate via gears, and drives the bevel gear to rotate via the end face gear plate, thereby enabling the cast iron furnace frame to rotate automatically, which improves the uniformity of spraying. The rotation of the cast iron furnace frame is particularly important when spraying the inner ring wall and outer ring surface of the cast iron furnace frame. Attached Figure Description

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0057] Example 1, referring to Figure 1-4 The first embodiment of the present invention provides a spraying device for the production and processing of enamel cast iron furnace frames, including a table 1, a spraying frame 2 connected to the table 1, a material feeding unit 3, a spraying unit 4, and a rotating unit 5; the spraying unit 4 is installed on the material feeding unit 3, and the spraying unit 4 can be a spray gun or a disc atomizer, used to spray enamel glaze onto the surface of the cast iron furnace frame on the material feeding unit 3; the rotating unit 5 is installed on the material feeding unit 3, and the rotating unit 5 can be a rotary motor, used to drive the material feeding unit 3 to rotate.

[0058] Reference Figure 1-3The material placement unit 3 is installed on the spraying frame 2 and is used to support and rotate the cast iron furnace frame. The material placement unit 3 includes: a drive component 31, which is set on the spraying frame 2 and is used to drive the cast iron furnace frame to move and provide power for the rotation of the cast iron furnace frame; the drive component 31 includes a servo motor 311 installed on the spraying frame 2, a lead screw 312 installed on the output end of the servo motor 311, a nut 313 installed on the lead screw 312, and a limiting slider 314 connected to the nut 313. A limiting groove 315 is opened on the inner side wall of the spraying frame 2, and the limiting slider 314 is slidably connected in the limiting groove 315.

[0059] Specifically, after the servo motor 311 is started, it drives the lead screw 312 to rotate, which in turn causes the lead screw 312 to move the nut 313. When the nut 313 moves, it drives the limit slider 314 to move accordingly. When the limit slider 314 moves within the limit groove 315, the path of the limit slider 314 remains stable.

[0060] Reference Figure 3-4 The placement component 32 is mounted on the drive component 31 and is used to support the cast iron furnace frame. The placement component 32 includes a U-shaped frame 321 mounted on the drive component 31. The U-shaped frame 321 and the limiting slider 314 are fixed together. A Z-shaped rod 322 is rotatably connected inside the U-shaped frame 321. An L-shaped rod 323 is connected to one end of the Z-shaped rod 322. A cylindrical tube 324 is located at the bottom of the L-shaped rod 323. A concave disc 325 is connected to the bottom of the cylindrical tube 324. A hydraulic cylinder 326 is installed inside the cylindrical tube 324. A movable disc 327 is installed at the output end of the hydraulic cylinder 326 and slides inside the concave disc 325. Four hinge rods 328 are hinged on the movable disc 327. A support rod 329 is hinged to the end of the hinge rod 328 away from the movable disc 327 and passes through the concave disc 325 and slides inside the concave disc 325.

[0061] Specifically, the cast iron furnace frame is placed outside the concave disc 325. The hydraulic cylinder 326 extends and drives the moving disc 327 to move down the concave disc 325. When the concave disc 325 moves down, it drives the hinge rod 328 to rotate. When the hinge rod 328 rotates, it drives the support rod 329 to move closer to the inner ring wall of the cast iron furnace frame. When the support rod 329 abuts against the inner ring wall of the cast iron furnace frame, the cast iron furnace frame is supported and fixed by the four support rods 329.

[0062] Reference Figure 3The flipping component 33 is installed on the placement component 32 and is used to drive the cast iron furnace frame to flip. The flipping component 33 includes a guide groove 331 opened on the spraying frame 2. The guide groove 331 includes three sets of horizontal grooves 3311 and two sets of inclined grooves 3312. The height of the three sets of horizontal grooves 3311 to the table surface 1 is different. The vertical distance between the uppermost horizontal groove 3311 and the middle horizontal groove 3311 is smaller than the vertical distance between the middle horizontal groove 3311 and the lowermost horizontal groove 3311. The two sets of inclined grooves 3312 are used to connect adjacent horizontal grooves 3311. The roller 332 is installed on the other end of the Z-shaped rod 322 and rolls in the guide groove 331.

[0063] Specifically, when the roller 332 rolls in the uppermost horizontal groove 3311 of the guide groove 331, the front of the cast iron furnace frame can be sprayed. When the roller 332 rolls from the uppermost horizontal groove 3311 to the middle horizontal groove 3311, it needs to pass through the inclined groove 3312 between the uppermost horizontal groove 3311 and the middle horizontal groove 3311. During the process of passing through the inclined groove 3312, the Z-shaped rod 322 will rotate 80°. When the Z-shaped rod 322 rotates, it will drive the L-shaped rod 323 to rotate. The cast iron furnace frame is rotated. When the roller 332 moves into the horizontal groove 3311 in the middle, the cast iron furnace frame is rotated. At this time, the spraying component 41 sprays the inner ring wall and outer ring surface of the cast iron furnace frame. When the Z-shaped rod 322 continues to move, the roller 332 moves into the horizontal groove 3311 at the bottom. Then, the Z-shaped rod 322 drives the L-shaped rod 323 and the cast iron furnace frame to rotate 100°. After two rotations, the cast iron furnace frame is rotated exactly 180°. After the rotation, the bottom surface of the cast iron furnace frame is sprayed with enamel glaze.

[0064] During use, the extension of the hydraulic cylinder 326 drives the hinge rod 328 to rotate, which in turn drives the support rod 329 to support and fix the cast iron furnace frame. Then, the servo motor 311 is started to drive the lead screw 312 to rotate, which in turn drives the nut 313 and the limiting slider 314 on the nut 313 to move. When the limiting slider 314 moves, it drives the U-shaped frame 321 to move. When the U-shaped frame 321 moves, it drives the Z-shaped rod 322 to move. When the Z-shaped rod 322 moves, it drives the roller 332 to roll in the guide groove 331. When the roller 332 rolls in the uppermost horizontal groove 3311 of the guide groove 331, the roller 332 rolls in the guide groove 331. After moving into the horizontal groove 3311 in the middle, the Z-shaped rod 322 rotates 80°, and drives the L-shaped rod 323 to rotate and the cast iron furnace frame to rotate 80°. At this time, the spraying component 41 sprays the inner ring wall and outer ring surface of the cast iron furnace frame. When the Z-shaped rod 322 continues to move, the roller 332 rolls from the horizontal groove 3311 in the middle of the guide groove 331 to the horizontal groove 3311 at the bottom. Then, the Z-shaped rod 322 drives the L-shaped rod 323 and the cast iron furnace frame to rotate 100°, so that the bottom surface of the cast iron furnace frame is turned upward. The spraying component 41 can spray enamel glaze onto the bottom surface of the cast iron furnace frame.

[0065] Example 2, refer to Figure 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the spraying unit 4 includes: a spraying component 41, which is disposed above the placement component 32 and is used to spray enamel glaze onto the surface of the cast iron furnace frame. The spraying component 41 includes a spraying device 411 mounted on the table 1, a guide hose 412 mounted on the spraying device 411, a guide tube 413 connected to the guide hose 412, a slot 414 opened on the spraying frame 2 for the guide tube 413 to slide, a storage box 415 connected to the end of the guide tube, and a plurality of spray nozzles 416 mounted on the bottom of the storage box 415.

[0066] Specifically, the two rotations of the Z-shaped rod 322 cause the position of the cast iron furnace frame to change, and the pushing component 42 will drive the storage box 415 and the nozzle 416 to move, thereby changing the position of the nozzle 416 so that the position of the nozzle 416 after the movement is always directly above the cast iron furnace frame. In addition, after the Z-shaped rod 322 first drives the cast iron furnace frame to rotate 80°, there is a 10° angle difference between the cast iron furnace frame and the nozzle 416, so that the enamel glaze sprayed by the nozzle 416 can be sprayed more fully onto the inner ring wall and outer ring surface of the cast iron furnace frame.

[0067] Reference Figure 5-6A pushing component 42, positioned above the spraying component 41, is used to push the spray nozzle 416 to move as the cast iron furnace frame rotates. The pushing component 42 includes a guide plate 421 connected to the outside of the material guide tube 413, a rectangular groove 422 formed on the top of the U-shaped frame 321, in which the guide plate 421 is slidably fitted, guide grooves 423 formed on the side walls of the rectangular groove 422, guide blocks 424 connected to both sides of the guide plate 421, in which the guide blocks 424 are slidably fitted, and cylindrical blocks 425 connected to the guide plate 421, a pushing plate 426 set on the top of the U-shaped frame 321, a pushing groove 427 formed in the pushing plate 426, the pushing groove 427 being inclined, in which the cylindrical blocks 425 are slidably fitted, and a limiting U-shaped clamping plate 42 connected to the top of the U-shaped frame 321. 8. A limiting groove is formed on the top of the push plate 426, and the limiting U-shaped card plate 428 is slidably fitted in the limiting groove. A connecting component 429 is set on the push component 42. When the flipping component 33 is working, the connecting component 429 drives the push component 42 to work. The connecting component 429 includes a rotating rod 4291 hinged to the top of the push plate 426. One end of the rotating rod 4291 is hinged to a moving rod 4292. A guide plate 4293 is connected to the inner wall of the U-shaped frame 321. The moving rod 4292 passes through the U-shaped frame 321 and the guide plate 4293 and slides within the U-shaped frame 321 and the guide plate 4293. A connecting rod 4294 is hinged to the bottom of the moving rod 4292. A toggle rod 4295 is hinged to the bottom of the connecting rod 4294. The end of the toggle rod 4295 away from the connecting rod 4294 is fixed to the outer side of the Z-shaped rod 322.

[0068] Specifically, when the Z-shaped rod 322 rotates, it drives the actuating rod 4295 and the connecting rod 4294 to rotate. When the connecting rod 4294 rotates, it drives the moving rod 4292 to move upward. When the moving rod 4292 moves upward, it drives the rotating rod 4291 to rotate. When the rotating rod 4291 rotates, it drives the pushing plate 426 to move. When the pushing plate 426 moves, it causes the pushing groove 427 to push the cylindrical block 425 and drive the guide plate 421 and the nozzle 416 to move. This causes the nozzle 416 to move to the top of the cast iron furnace frame after it is flipped. However, due to the setting of the limiting U-shaped card plate 428 and the limiting groove, the movement path of the pushing plate 426 is constrained. In addition, due to the guide groove 423 and the guide blocks 424 on both sides of the guide plate 421, when the nozzle 416 moves, the guide blocks 424 move with it in the guide groove 423, thus constraining the movement path of the nozzle 416. The nozzle 416 is always located above the cast iron furnace frame.

[0069] During use, as the cast iron furnace frame moves, the spray nozzle 416 continuously sprays the frame. When the Z-shaped rod 322 rotates the cast iron furnace frame, it first rotates the actuating rod 4295 and the furnace frame by 80°. At this time, the rotation of the actuating rod 4295 causes the connecting rod 4294 to rotate, which in turn moves the moving rod 4292 upwards and rotates the rotating rod 4291. This, in turn, moves the pushing plate 426, causing it to move the spray nozzle 416, positioning it directly above the rotated cast iron furnace frame. Meanwhile, the connecting rod 4294 and the moving rod... There is still an angle difference between 4292 and the lever 4295. When the cast iron furnace frame is rotated 100° for the second time, the bottom surface of the cast iron furnace frame is rotated to the top. This process can be understood as rotating 10° plus rotating 90°. When rotating 10°, the nozzle 416 will continue to move in the direction of the first movement. After rotating 10°, the moving lever 4292, the connecting lever 4294, and the lever 4295 are in a straight line. Then, it is rotated 90° again, which drives the nozzle 416 to move in the opposite direction and move to the initial position, that is, to move directly above the cast iron furnace frame.

[0070] The remaining structure is the same as that in Example 1.

[0071] Example 3, referring to Figure 2-3 as well as Figure 6-9 This is the third embodiment of the present invention, which differs from the second embodiment in that: the rotating unit 5 includes: a self-rotating component 51, disposed above the placement component 32, for driving the cast iron furnace frame to rotate; the self-rotating component 51 includes a first rotating shaft 511 connected to the cylindrical tube 324, and the first rotating shaft 511 passes through the L-shaped plate and is rotatably connected to the L-shaped plate through an embedded bearing; a bevel gear 512 is connected to the top of the first rotating shaft 511; a second rotating shaft 513 is rotatably connected inside the U-shaped frame 321; an end face gear 514 is connected to one end of the second rotating shaft 513, and the bevel gear 512 and the end face gear 514 mesh with each other; a gear 515 is connected to the other end of the second rotating shaft 513, and the second rotating shaft 513 and the gear 515 are rotatably connected through a first bearing; a single-sided toothed groove 516 is opened in the spray frame 2, and the gear 515 rolls in the single-sided toothed groove 516 and meshes with the single-sided toothed groove 516.

[0072] Specifically, when the U-shaped frame 321 moves, it drives the second rotating shaft 513 to move accordingly. When the second rotating shaft 513 moves, it drives the gear 515 to roll in the single-sided tooth groove 516. When the gear 515 rotates, it drives the second rotating shaft 513 and the end face toothed disc 514 to rotate. When the end face toothed disc 514 rotates, it drives the bevel gear 512 and the first rotating shaft 511 to rotate. When the first rotating shaft 511 rotates, it drives the cylindrical cylinder 324 and the cast iron furnace frame to rotate. This allows the cast iron furnace frame to rotate while moving, so that the cast iron furnace frame can be sprayed more evenly. Especially when spraying the inner ring wall and outer ring surface of the cast iron furnace frame, the rotation of the cast iron furnace frame allows the enamel glaze to be sprayed better on its surface.

[0073] Reference Figure 7-8 Separating component 52, positioned above rotating component 51, is used to decouple the synchronous rotation between end face gear disk 514 and gear 515. Separating component 52 includes multiple triangular teeth 521 connected to the end face of gear 515, with the multiple triangular teeth 521 arranged in a ring with uniform and equidistant spacing. An annular sleeve 522 is fitted outside the second rotating shaft 513. One end face of the annular sleeve 522 has multiple triangular grooves 523 arranged in a ring with uniform and equidistant spacing, and the triangular teeth 521 and triangular grooves 523 mesh with each other. A pressure plate 524, rotatably connected to the outside of the annular sleeve 522 via a second bearing, is connected to the inner side of the spray frame 2. Two sets of extrusion plates 525, the positions of the two sets of extrusion plates 525 correspond to the positions of the inclined grooves 3312 in the guide groove 331, four protrusions 526 connected to the inner side of the annular sleeve 522, four slots 527 opened on the outer side of the second rotating shaft 513, and the protrusions 526 slidingly engaged with the corresponding slots 527, the guide rods 528 connected in the slots 527, and the guide rods 528 passing through the protrusions 526 and sliding within the protrusions 526, and the elastic element 529 sleeved outside the guide rods 528, and the two ends of the elastic element 529 abutting against the protrusions 526 and the inner walls of the slots 527 respectively.

[0074] Specifically, before the cast iron furnace frame flips, the pressure plate 524 on the annular sleeve 522 moves to the position of the extrusion plate 525. As it continues to move, the pressure plate 524 is squeezed by the extrusion plate 525, causing the pressure plate 524 to drive the annular sleeve 522 away from the gear 515. When the triangular teeth 521 on the gear 515 and the triangular grooves 523 on the annular sleeve 522 separate, the cast iron furnace frame flips, causing the bevel gear 512 to flip as well. The flipping of the bevel gear 512 causes the end face gear disk 514 to rotate. Meanwhile, the second rotating shaft 513 continues to drive the gear 515 to rotate as it moves. At this time, the rotation of the gear 515 and the end face gear disk 514 rotate independently, without being constrained by each other, thus preventing the rotation of the gear 515 from causing... The end face gear 514 rotates, and the bevel gear 512 also rotates, causing the end face gear 514 to rotate. The two movements are mutually exclusive. By allowing the gear 515 to rotate and the end face gear 514 to rotate independently, without being constrained by each other, the problem of gear jamming is avoided. After the cast iron furnace frame completes its rotation, the pressure plate 524 moves off the extrusion plate 525. Under the rebound force of the elastic element 529, it drives the annular sleeve 522 and the pressure plate 524 to move. At this time, the triangular groove 523 on the annular sleeve 522 meshes with the triangular tooth 521 on the gear 515. That is, when the second rotating shaft 513 continues to move, the rotation of the gear 515 will drive the second rotating shaft 513 to rotate, which in turn drives the end face gear 514 to rotate, and then drives the cast iron furnace frame to rotate again.

[0075] During use, the elastic element 529 can be a spring or similar device. In its normal state, the triangular teeth 521 on the gear 515 and the triangular groove 523 on the annular sleeve 522 are meshed. When the second rotating shaft 513 moves, it drives the gear 515 to rotate within the single-sided tooth groove 516, thus causing the gear 515 to rotate the annular sleeve 522. The rotation of the annular sleeve 522 then drives the second rotating shaft 513 to rotate, which in turn drives the end face gear disc 514 to rotate, thereby driving the bevel gear 512 to rotate. The rotation of the bevel gear 512 then drives the cast iron furnace frame to rotate. Before the cast iron furnace frame is rotated, the extrusion plate 525 presses against the pressure plate 5. 24, causing the pressure plate 524 to move the annular sleeve 522, causing the triangular groove 523 on the annular sleeve 522 and the triangular tooth 521 on the gear 515 to separate. Moreover, the second rotating shaft 513 and the gear 515 are rotatably connected through the first bearing, so that the subsequent rotation of the gear 515 will not drive the second rotating shaft 513 to rotate. When the cast iron furnace frame flips, it drives the bevel gear 512 to flip. When the bevel gear 512 flips, it drives the end face gear disk 514 to rotate, which in turn drives the second rotating shaft 513 to rotate. In this process, the rotation of the second rotating shaft 513 will not drive the gear 515 to rotate. That is, the rotation of the gear 515 and the end face gear disk 514 rotate independently and are not constrained by each other.

[0076] The remaining structure is the same as that in Example 2.

[0077] Example 4, refer to Figure 1-9 The fourth embodiment of the present invention provides a method for using a spraying device for the production and processing of enamel cast iron furnace frames, comprising the following steps:

[0078] S1: Place the cast iron furnace frame outside the concave disc 325. The hydraulic cylinder 326 retracts, causing the moving disc 327 to move upward. The moving disc 327 moves upward, causing the support rod 329 to move closer to the inner ring wall of the cast iron furnace frame. When the support rod 329 abuts against the inner ring wall of the cast iron furnace frame, the cast iron furnace frame is fixed. At this time, the spraying component 41 sprays enamel glaze onto the front of the cast iron furnace frame.

[0079] S2: Simultaneously, the motor is started, causing the lead screw to rotate, which in turn moves the limit block, U-shaped frame 321, and cast iron furnace frame. As the U-shaped frame 321 moves, it drives the Z-shaped rod 322 to move. As the Z-shaped rod 322 moves, its roller 332 at one end rolls within the guide groove 331. When the roller 332 rolls from the uppermost horizontal groove 3311 to the middle horizontal groove 3311 within the guide groove 331, the Z-shaped rod 322 rotates 80°. The Z-shaped rod 322 then drives the L-shaped... As rod 323 rotates and cast iron furnace frame rotates 80°, spraying component 41 sprays the inner ring wall and outer ring surface of cast iron furnace frame. When Z-shaped rod 322 continues to move, roller 332 rolls from the middle horizontal groove 3311 in guide groove 331 to the bottom horizontal groove 3311. Z-shaped rod 322 rotates 100°, and Z-shaped rod 322 drives L-shaped rod 323 and cast iron furnace frame to rotate 100°. Spraying component 41 sprays enamel glaze onto the bottom surface of cast iron furnace frame.

[0080] S3: During both rotations, the Z-shaped rod 322 drives the nozzle 416 to move. The rotation of the Z-shaped rod 322 drives the actuating rod 4295 to rotate, which in turn drives the connecting rod 4294 to rotate. The rotation of the connecting rod 4294 then drives the moving rod 4292 to move upwards. The upward movement of the moving rod 4292 drives the rotating rod 4291 to rotate, which in turn drives the push plate 426 to move, causing the push groove 427 to push the cylindrical block. 425 and drive the guide plate 421 and the nozzle 416 to move. When the cast iron furnace frame is rotated 80°, and it is necessary to spray enamel glaze on the inner ring wall and outer ring surface of the cast iron furnace frame, the position of the cast iron furnace frame changes. At this time, the nozzle 416 will move to the top of the rotated cast iron furnace frame. After the cast iron furnace frame continues to rotate 100°, when it is necessary to spray enamel glaze on the bottom surface of the cast iron furnace frame, the nozzle 416 will also move to the top of the cast iron furnace frame.

[0081] S4: When the U-shaped frame 321 moves, it drives the cast iron furnace frame to rotate. When the U-shaped frame 321 moves, it drives the second rotating shaft 513 to move. When the second rotating shaft 513 moves, it drives the gear 515 to roll in the tooth groove, which in turn drives the second rotating shaft 513 and the end face gear plate 514 to rotate. When the end face gear plate 514 rotates, it drives the bevel gear 512, the cylindrical tube 324 and the cast iron furnace frame to rotate.

[0082] S5: Before the Z-shaped rod 322 drives the cast iron furnace frame to rotate, the movement of the second rotating shaft 513 will drive the moving disc to move accordingly. Before the Z-shaped rod 322 moves into the inclined groove 3312 of the guide groove 331, the pressure plate 524 on the moving disc is squeezed by the extrusion plate 525, causing the pressure plate 524 to drive the moving disc to move away from the gear 515. When the triangular teeth 521 on the gear 515 separate from the triangular groove 523 on the moving disc, the cast iron furnace frame drives the bevel gear 512 to rotate when it rotates. The rotation of the bevel gear 512 drives the end face gear disc 514 to rotate, while the second rotating shaft 513... During movement, the gear 515 will continue to rotate. At this time, the gear 515 and the end face gear 514 rotate independently and are not constrained by each other. When the cast iron furnace frame has completed its rotation, the pressing plate 525 no longer presses the pressure plate 524. Under the rebound force of the elastic element 529, the moving disc and the pressure plate 524 move. At this time, the triangular groove 523 on the moving disc and the triangular tooth 521 on the gear 515 mesh. That is, when the second rotating shaft 513 continues to move, the rotation of the gear 515 will drive the second rotating shaft 513 to rotate, which in turn drives the end face gear 514 to rotate, thereby driving the bevel gear 512 and the cast iron furnace frame to rotate.
