Description

Technical Field

[0001] This invention relates to the field of foamed ceramic production technology, and in particular to an automated production line and method for foamed ceramic prefabricated wall panels. Background Technology

[0002] Foamed ceramics are a new type of building material that has only been produced and applied in my country in recent years. It is a foamed material with ceramic physical characteristics, and also possesses excellent properties such as light weight, good wear resistance, low thermal conductivity, good fire resistance, good sound insulation, and a coefficient of thermal expansion of 0. Using prefabricated construction methods can shorten the construction period by 60% and save 40% in costs compared to brick and stone wall materials. While being economical in cost, it also significantly improves construction quality and efficiency.

[0003] Currently, the surface carving of foamed ceramics is processed using carving techniques and equipment similar to those used for stone and bricks. These processes rely on single machines and manual loading and unloading. Products such as relief carvings require multiple machines to be processed simultaneously, and standardized mass production is not possible. Therefore, to address the problems of difficulty in accurately aligning materials due to manual loading and unloading in existing technologies, and the risk of surface defects caused by bumps during the loading process, we propose a new type of automated production line and method for foamed ceramic prefabricated wall panels. Summary of the Invention

[0004] To overcome the aforementioned shortcomings in the prior art, the present invention aims to provide an automated production line and method for foamed ceramic prefabricated wall panels that can automatically feed materials and automatically adjust their position to facilitate subsequent CNC machine tool engraving.

[0005] In a first aspect, an automatic production line for foamed ceramic assembled walls is provided, including a carving module, a transfer mechanism, and a conveying mechanism supporting the transfer mechanism. The carving module includes a carving machine operation table with an upward opening and an overall rectangular box-like structure. On one outer wall of the carving machine operation table, a double-axis numerical control machine tool is provided, and a carving mechanism is arranged at the top of the double-axis numerical control machine tool. The transfer mechanism includes a support frame arranged on the side of the carving machine operation table away from the double-axis numerical control machine tool. A main bearing seat is fixed at the top of the support frame, and an anti-displacement bearing is clamped in the main bearing seat. A support pipe is rotatably connected in the anti-displacement bearing, and a rotary plate is fixed at the top of the support pipe. The overall rotary plate is in a long strip structure, and symmetrically hinged spoon-shaped support rods are respectively arranged near both ends of the upper surface of the rotary plate. Symmetric clamping plate mechanisms are respectively fixed at the ends of the two spoon-shaped support rods away from each other, and the hinge points of the spoon-shaped support rods are close to the spoon handle ends. The clamping plate mechanism includes a support plate body fixed at the end of the spoon-shaped support rod away from the spoon handle end. When the support plate body is in a horizontal state, it is lower than the top opening of the carving machine operation table, which can prevent the water used for flushing during carving from flowing out of the carving machine operation table. In the middle of the conveying machine frame, there is a downward concave conveyor belt, and the concave part of the conveyor belt is adapted to the overall clamping plate mechanism during feeding.

[0006] Preferably, the carving mechanism includes a telescopic cantilever fixed above the double-axis numerical control machine tool and extending above the carving machine operation table. A carving main body is fixed at the end of the telescopic cantilever, and a milling cutter head is arranged at the bottom of the carving main body. A water pump mechanism is fixed on the side of the double-axis numerical control machine tool away from the carving machine operation table, and two water delivery pipes are arranged at the output end of the water pump mechanism. Spray pipes communicated with the water delivery pipes are respectively fixed on both sides of the carving main body, and the spraying directions of the two spray pipes are spirally distributed on the outer wall of the milling cutter head, which can make the muddy water generated during carving generate vortices and centrifugal forces, and can quickly throw the muddy water out of the carving center position, reducing the interference to the carving position.

[0007] Preferably, symmetric support columns are respectively fixed at the four corners of the bottom of the groove of the carving machine operation table near the support plate body in a horizontal state, and the four support columns are of the same height and do not contact the support plate body. The length direction of the support plate body is perpendicular to the conveying direction of the conveyor belt, and the middle parts of the two long sides of the support plate body are simultaneously recessed towards the middle, making the entire support plate body in a waisted structure. Auxiliary rollers protruding by one-fourth are arranged near the four corners of the upper surface of the support plate body, and the axis lines of the auxiliary rollers are perpendicular to the conveying direction of the conveyor belt.

[0008] Preferably, a driven gear ring is fixed to the outer circumference of the support tube near the bottom end, and an electric push rod of the same height as the driven gear ring is fixed on the support frame. The extension center line of the electric push rod is tangent to the outer circumference of the driven gear ring, and a rack push-pull rod tangent to the driven gear ring is fixed to the end of the extension rod of the electric push rod, which can drive the two tilted clamping plate mechanisms and the return plate to rotate 180 degrees.

[0009] Preferably, the return plate has a central hole, and a hydraulic jack is fixedly engaged in the hole. Two symmetrical steel ropes are fixed to the top of the hydraulic jack's extension rod. Rectangular grooves, arranged symmetrically at both ends, are formed on the upper surface of the return plate. A convex hinge seat is fixed to the bottom of each of the two rectangular grooves away from the hydraulic jack. Two spoon-shaped support rods are hinged to the tops of the two convex hinge seats. Pulley grooves, arranged symmetrically at the bottom of each of the two rectangular grooves near the central hole, are formed on the bottom of each rectangular groove. A fixed pulley is rotatably connected to each of the two pulley grooves. The two steel ropes pass through the fixed pulley on their respective sides and are fixed to the handles of the corresponding spoon-shaped support rods. When the clamping mechanism needs to be lifted after loading, simply extend the hydraulic jack.

[0010] Preferably, the conveyor frame includes side guard plates that are parallel to each other on both sides of the conveyor belt, and the side guard plate near the return plate has an embedded groove recessed towards the return plate in the middle, and the bottom of the embedded groove is reserved with a slanted plate support block, which can ensure that when the spoon-shaped support rod lowers the clamping mechanism end as a whole, it will not lower too much and cause it to press against the surface of the conveyor belt, thereby playing a protective role for the conveyor belt.

[0011] Preferably, parallel steering top rods and steering bottom rods are fixed on both sides of the two side guard plates of the conveyor frame near the recess. The two steering top rods are of equal height and the same diameter, and the two steering bottom rods are of equal height and the same diameter. The distance between the two steering top rods is adapted to the width of the pallet body. Both the steering top rods and the steering bottom rods can rotate as a whole.

[0012] Preferably, the lower surface of the pallet body has two symmetrically spaced, interlocking grinding gears near the center. Between these grinding gears, two symmetrical angle steel rails are fixed to the lower surface of the pallet body. A single L-shaped double-sided toothed rod is slidably connected between the two angle steel rails. This L-shaped double-sided toothed rod meshes with both grinding gears, causing them to rotate in reverse. A clamping plate is located on the upper surface of the pallet body near the end of the L-shaped double-sided toothed rod. Parallel grinding gears are also provided on the lower surface of the pallet body near the narrow waist on both sides. The symmetrical rack and pinion rods mesh with two rubbing gears respectively. The lower surface of the support plate body is provided with shaft seats at both ends of the rack and pinion rods to guide their sliding. The ends of the two rack and pinion rods away from the first clamping plate are fixed with gate-shaped clamping plates that are parallel to the surface of the first clamping plate. The end of the L-shaped double-sided rack and pinion rod away from the first clamping plate is fixed with a return spring, and the other end of the return spring is fixed with a spring stop. The end of the L-shaped double-sided rack and pinion rod near the return spring is fixed with a steel wire, and the extension direction of the spoon-shaped support rod is consistent with the extension direction of the steel wire.

[0013] Preferably, an electric push rod 2 is fixed to the upper surface of the spoon-shaped support rod near the end of the spoon handle, and two pulley frames 1 are fixed to the end of the upper surface of the spoon-shaped support rod away from the electric push rod 2. Each pulley frame 1 is equipped with an anti-detachment pulley. The other end of the steel wire 1 passes around the two anti-detachment pulleys and is fixed to the end of the extension rod. When the steel wire 1 needs to be pulled, it is only necessary to control the extension rod of the corresponding electric push rod 2 to extend.

[0014] Secondly, an automated production method for foamed ceramic prefabricated wall panels is provided, including the following steps:

[0015] S1: Before loading, control the return plate to rotate so that both ends are directly opposite the recesses of the conveyor belt and the middle of the engraving machine operating table; then control the extension rod of the hydraulic push rod to retract to the initial state, that is, lower the clamping plate mechanism at both ends of the return plate, with the plate body of one end sinking into the recess of the conveyor belt and flush with the working surface of the conveyor belt; the plate body of the other clamping plate mechanism rests on the upper surface of the four support columns.

[0016] S2: Control the clamping mechanism on the conveyor belt to release clamping plate one and gate clamping plate two. After the first raw material plate is pushed between the two, clamp it again. Then control the extension rod of the hydraulic push rod to extend so as to lift the clamped first raw material plate and the clamping mechanism as a whole. At this time, the clamping mechanism near the end of the engraving machine operating table is also lifted. Then start the electric push rod one to change the position of the two clamping mechanisms as a whole. Finally, put the two clamping mechanisms down. At this time, the engraving module can be started to engrave.

[0017] S3: During engraving, the other end of the clamping mechanism is perfectly embedded in the recess, and then the second raw material plate is fed. After the engraving is completed, the previous repositioning action is performed again, and the first finished piece that has been engraved is rotated back to the recess above the conveyor belt. At the same time, the two clamping mechanisms are lowered. At this time, the second raw material plate at the engraving position continues to be engraved. The engraved finished product is then conveyed backward by the conveyor frame. Then, the third raw material plate that has not been engraved at the incoming end is pushed onto the clamping mechanism that has just been emptied and waits.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. By setting two mutually symmetrical clamping mechanisms, not only can automatic feeding and engraving be carried out simultaneously, but the position of the raw material plate does not need to be readjusted during engraving. Moreover, the engraved workpiece can be turned back to the feeding position and continued to be transported along the same conveyor line, saving space and conveyor lines.

[0020] 2. By setting auxiliary rollers protruding from the upper surface of the pallet body, the raw material plate can be loaded and positioned by simply pushing it with a little force during loading or unloading, thus reducing frictional wear on the raw material plate.

[0021] 3. When it is necessary to clamp the raw material plate above the pallet body by using the clamping plate and two counter-moving rack rods, simply pull the steel wire to move the clamping plate and the gate-shaped clamping plate to the center simultaneously, thereby fixing each raw material plate in a fixed position, which facilitates the precise identification and carving of the carving module.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In this embodiment, refer to Figures 1-11, this solution provides an automatic production line for foamed ceramic prefabricated walls, which includes a carving module, a transfer mechanism, and a conveying mechanism supporting the transfer mechanism. The carving module includes a carving machine operation table 1 with an upward opening and an overall cuboid box-like structure. On one outer wall of the carving machine operation table 1, there is a double-axis numerical control machine tool 15, and a carving mechanism is arranged at the top of the double-axis numerical control machine tool 15; the transfer mechanism includes a support frame 2 arranged on the side of the carving machine operation table 1 away from the double-axis numerical control machine tool 15. A main bearing seat 24 is fixed at the top of the support frame 2, and an anti-runaway bearing is clamped in the main bearing seat 24. A support tube 25 is rotatably connected in the anti-runaway bearing, and a rotating support plate 9 is fixed at the top of the support tube 25. The overall shape of the rotating support plate 9 is strip-shaped, and symmetrically hinged at both ends on the upper surface of the rotating support plate 9 are mutually symmetrical spoon-shaped support rods 13. At the ends of the two spoon-shaped support rods 13 away from each other, mutually symmetrical clamping plate mechanisms 5 are fixed respectively, and the hinge points of the spoon-shaped support rods 13 are close to the spoon handle ends. The clamping plate mechanism 5 includes a support plate body fixed at the end of the spoon-shaped support rod 13 away from the spoon handle end. When the support plate body is in a horizontal state, it is lower than the top opening of the carving machine operation table 1, which can prevent the water used for flushing during carving from flowing out of the carving machine operation table 1. In the middle of the conveying rack 7, there is a downwardly concave conveyor belt 8, and the concave part of the conveyor belt 8 is adapted to the overall clamping plate mechanism 5. During feeding, only need to rotate one of the clamping plate mechanisms 5 to the concave conveyor belt 8, that is, the support plate body is in a horizontal state. At this time, the whole clamping plate mechanism 5 just fits into the concave part, and the upper surface of the support plate body is flush with the conveying surface of the conveyor belt 8. Then, the raw material plate can be pushed into the clamping plate mechanism 5. After being clamped, lift the whole and rotate it 180 degrees, then the raw material plate can be rotated to the carving position. The finished product at the other end of the rotating support plate 9 and the other clamping plate mechanism 5 will rotate back above the concave part of the conveyor belt 8, and then lower the two clamping plate mechanisms 5 at the same time. At this time, the raw material plate at the carving position continues to be carved, and the finished product carved at the conveying rack 7 is continuously conveyed backward, and then the uncarved raw material plate at the feeding end is continuously pushed onto the just vacated clamping plate mechanism 5 and wait.

[0036] Refer to Figure 1 and Figure 11 , the carving mechanism includes a telescopic cantilever fixed above the double-axis numerical control machine tool 15 and extending above the carving machine operation table 1. A carving main body 14 is fixed at the end of the telescopic cantilever, and a milling cutter head 141 is arranged at the bottom of the carving main body 14; on one side of the double-axis numerical control machine tool 15 away from the carving machine operation table 1, a water pump mechanism 16 is fixed, and two conveying water pipes are arranged at the output end of the water pump mechanism 16. Spray pipes 21 connected to the conveying water pipes are respectively fixed on both sides of the carving main body 14, and the spraying directions of the two spray pipes 21 are spirally distributed on the outer wall of the milling cutter head 141. By setting like this, the muddy water generated during carving can generate vortex and centrifugal force, and the muddy water can be quickly thrown out of the carving center position, reducing the interference to the carving position.

[0037] Reference Figure 1 and Figure 10 The bottom of the engraving machine operating table 1 has four symmetrical support columns 17 fixed at the four corners of the horizontal pallet body. The four support columns 17 are of equal height and do not contact the pallet body. The length direction of the pallet body is perpendicular to the conveying direction of the conveyor belt 8. The two long sides of the pallet body are concave towards the middle, making the entire pallet body have a narrow waist structure. The upper surface of the pallet body is provided with auxiliary rollers 6 that protrude one-quarter of the way near the four corners. The axis of the auxiliary rollers 6 is perpendicular to the conveying direction of the conveyor belt 8. By setting the auxiliary rollers 6 that protrude from the upper surface of the pallet body, the material can be loaded and positioned by simply pushing the material plate with a little force when loading or unloading, thus reducing frictional wear on the material plate.

[0038] Reference Figure 1 , Figure 2 and Figure 5 A driven gear ring 20 is fixed near the bottom of the outer circumference of the support tube 25, and an electric push rod 3 of the same height as the driven gear ring 20 is fixed on the support frame 2. The extension center line of the electric push rod 3 is tangent to the outer circumference of the driven gear ring 20, and a rack push-pull rod 4 tangent to the driven gear ring 20 is fixed at the end of the extension rod of the electric push rod 3. The rack push-pull rod 4 can drive the two raised clamping plate mechanisms 5 and the return plate 9 to rotate 180 degrees.

[0039] Reference Figure 1 , Figure 5 and Figure 7 The return plate 9 has a circular hole 901 in the middle, and a hydraulic jack 10 is fixedly engaged in the circular hole 901. Two symmetrical steel ropes 23 are fixed to the top of the extension rod of the hydraulic jack 10. The upper surface of the return plate 9 has rectangular grooves 902 that are centrally symmetrically distributed near both ends. A convex hinge seat 12 is fixed to the bottom of each of the two rectangular grooves 902 away from the hydraulic jack 10. Two spoon-shaped support rods 13 are respectively hinged to the top of the two convex hinge seats 12. Furthermore, the bottom of the two rectangular grooves 902 near the end of the circular hole 901 is respectively provided with pulley grooves 903 that are centrally symmetrically distributed. Each of the two pulley grooves 903 is rotatably connected to a fixed pulley 11. Two steel ropes 23 pass through the fixed pulley 11 on their respective sides and are fixed to the handle of the corresponding spoon-shaped support rod 13. When it is necessary to lift the clamping mechanism 5 after feeding by means of the hydraulic push rod 10 and the steel ropes 23, it is only necessary to control the extension rod of the hydraulic push rod 10 to extend.

[0040] Reference Figures 5-6The conveyor frame 7 includes side guards that are parallel to each other on both sides of the conveyor belt 8. The side guards near the return plate 9 have an embedded groove recessed towards the return plate 9 in the middle. The bottom of the embedded groove is reserved with a slanted plate support block 701. The slanted plate support block 701 ensures that when the spoon-shaped support rod 13 lowers the end of the clamping mechanism 5 as a whole, it will not drop too much and press the entire surface of the conveyor belt 8, thus protecting the conveyor belt 8.

[0041] Reference Figures 5-6 Between the two side guard plates of the conveyor frame 7, near the recessed area, there are two parallel steering top rods 18 and steering bottom rods 19. The two steering top rods 18 are of the same height and diameter, and the two steering bottom rods 19 are of the same height and diameter. The distance between the two steering top rods 18 is adapted to the width of the pallet body. The steering top rods 18 and the steering bottom rods 19 can rotate as a whole. With this setting, it can be ensured that the conveyor belt 8 can still operate normally in the recessed area.

[0042] Reference Figure 5 , Figure 9 , Figure 10 Two symmetrical, gapped rubbing gears 27 are provided near the center of the lower surface of the pallet body. Two symmetrical angle steel slide rails 35 are fixed between the two rubbing gears 27 on the lower surface of the pallet body. A single L-shaped double-sided toothed rod 31 is slidably connected between the two angle steel slide rails 35. The L-shaped double-sided toothed rod 31 meshes with both rubbing gears 27 simultaneously, causing them to rotate in reverse. A clamping plate 30 is provided on the upper surface of the pallet body near the end of the L-shaped double-sided toothed rod 31. Parallel and symmetrical rack push rods 29 are provided on both sides of the lower surface of the pallet body near the narrow waist. The two rack push rods 29 mesh with the two rubbing gears 27 respectively. Guide rack push rods 29 are provided at both ends of the rack push rods 29 on the lower surface of the pallet body. The movable shaft seat 28 and the two rack top rods 29 are fixed with a gate-shaped clamping plate 32 parallel to the surface of the clamping plate 30 at the ends away from the clamping plate 30. The L-shaped double-sided rack 31 is fixed with a return spring 34 at the end away from the clamping plate 30, and a spring stop block 33 is fixed at the other end of the return spring 34. The L-shaped double-sided rack 31 is fixed with a steel wire 22 at the end near the return spring 34, and the extension direction of the spoon-shaped support rod 13 is consistent with the extension direction of the steel wire 22. When it is necessary to clamp the raw material plate above the support plate body by using the clamping plate 30 and the two rack top rods 29 running in opposite directions, it is only necessary to pull the steel wire 22 to move the clamping plate 30 and the gate-shaped clamping plate 32 to the middle at the same time, so that each raw material plate can be fixed in a fixed position, which facilitates the accurate identification and engraving of the engraving module.

[0043] Reference Figure 5 , Figure 9 , Figure 10 An electric push rod 2 is fixed to the upper surface of the spoon-shaped support rod 13 near the end of the spoon handle, and two pulley frames 26 are fixed to the end of the upper surface of the spoon-shaped support rod 13 away from the electric push rod 2. Each pulley frame 26 is equipped with an anti-detachment pulley. The other end of the steel wire 22 passes around the two anti-detachment pulleys and is fixed to the end of the extension rod. When the steel wire 22 needs to be pulled, it is only necessary to control the extension rod of the corresponding electric push rod 2 to extend.

[0044] This solution also provides an automated production method for foamed ceramic prefabricated wall panels, including the following steps:

[0045] S1: Before loading, control the return plate 9 to rotate until both ends are directly opposite the recesses of the conveyor belt 8 and the middle position of the engraving machine operating table 1; then control the extension rod of the hydraulic push rod 10 to retract to the initial state, that is, lower the clamping mechanism 5 at both ends of the return plate 9, with the plate body of one end sinking into the recess of the conveyor belt 8 and flush with the working surface of the conveyor belt 8; the plate body of the other clamping mechanism 5 rests on the upper surface of the four support columns 17.

[0046] S2: Control the clamping plate 30 and the gate-shaped clamping plate 32 on the clamping mechanism 5 on the control conveyor belt 8 to loosen. After the first raw material plate is pushed between the two, clamp it again. Then control the extension rod of the hydraulic push rod 10 to extend so as to lift the clamped first raw material plate and the clamping mechanism 5 as a whole. At this time, the clamping mechanism 5 near the end of the engraving machine operating table 1 is also lifted. Then start the electric push rod 3 to change the position of the two clamping mechanisms 5 as a whole. Finally, put the two clamping mechanisms 5 down. At this time, the engraving module can be started to engrave.

[0047] S3: During engraving, the other end clamping mechanism 5 is perfectly embedded in the recess, and the second raw material plate is then fed. After the engraving is completed, the previous repositioning action is performed again, and the first finished piece that has been engraved is rotated back to the recess of the conveyor belt 8. At the same time, the two clamping mechanisms 5 are lowered. At this time, the second raw material plate at the engraving position continues to be engraved. The engraved finished product is then conveyed backward at the conveyor frame 7. After that, the third raw material plate that has not been engraved at the incoming end is pushed onto the clamping mechanism 5 that has just been emptied and waits.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
