Description

[Technical Field]

[0001] This invention relates to the field of foamed brick production equipment technology, and in particular to a foamed brick slitting production line and slitting method. [Background Technology]

[0002] Foamed bricks, also known as foamed cement bricks or foamed concrete bricks, are a new type of energy-saving building material that utilizes waste, is environmentally friendly, energy-efficient, inexpensive, and non-combustible. They possess excellent properties such as lightweight, heat insulation, sound insulation, and fire resistance, making them ideal for non-load-bearing walls. Foamed bricks are made by adding chemical or physical foaming agents to a slurry composed of cementitious materials, admixtures, modifiers, and brine, followed by mixing, pouring, and natural curing to form a concrete product with numerous closed pores and considerable strength.

[0003] Currently, in the manufacturing of foamed bricks, large bricks are typically cast first, and then cut into smaller pieces of the required size. Therefore, a brick cutting device is an essential piece of equipment in foamed brick production. For example, Chinese invention patent application number CN201710233231.0 discloses a block cutting production line, which includes a frame and a main conveying device mounted on the frame. A first cutter, a second cutter, and a third cutter are sequentially mounted on the frame. A transverse material distribution and flipping mechanism that rotates the blocks 90 degrees is set between the first and second cutters, and a reversing mechanism that changes the direction of the blocks is set between the second and third cutters. This block cutting production line is suitable for cutting concrete blocks and foamed brick blocks, and can automatically cut the blocks on all six sides with high production efficiency.

[0004] Existing cutting production lines typically involve first slicing large bricks into sheet bricks, and then further cutting these sheet bricks into smaller foamed bricks. However, the applicant discovered that during actual casting, the top of the mold frame is open, resulting in an uneven top surface on the large bricks. This leads to uneven end faces on the foamed bricks positioned above the large bricks after cutting, affecting the quality of the foamed bricks. Grinding the uneven end faces of each foamed brick individually would significantly reduce production efficiency. In light of these problems, the inventors conducted in-depth research, leading to this application. [Summary of the Invention]

[0005] The technical problem to be solved by the present invention is to provide a foamed brick slitting production line and slitting method, which adopts the method of smoothing the top surface of large bricks before cutting them, so as to ensure the cutting production efficiency of foamed bricks and the quality of foamed bricks after cutting, thereby effectively solving the problem that the uneven top surface of large bricks affects the quality of foamed bricks.

[0006] This invention is implemented as follows:

[0007] In a first aspect, a foamed brick slitting production line includes a production line conveyor, a finishing mechanism, and a first cutting machine; the finishing mechanism and the first cutting machine are both mounted on the production line conveyor, and the finishing mechanism is located upstream of the first cutting machine.

[0008] Furthermore, the finishing mechanism includes a support structure, a plurality of finishing cutter discs disposed above the conveyor belt, and a plurality of drive motors fixed on the support structure; each finishing cutter disc is on the same horizontal plane, and each finishing cutter disc can cover the top surface of a large brick during finishing; each finishing cutter disc is connected to the output end of one of the drive motors.

[0009] Furthermore, the face trimming mechanism also includes a cutter head connecting seat, the face trimming cutter head is locked to the bottom surface of the cutter head connecting seat, and the outer diameter of the face trimming cutter head is larger than the outer diameter of the bottom surface of the cutter head connecting seat; a bushing is provided with an upward extension from the top center of the cutter head connecting seat, the output shaft of the drive motor is fixedly sleeved in the bushing, and the upper end of the bushing abuts against the support structure.

[0010] Furthermore, a boss is formed in the middle of the top surface of the cutter head connecting seat, and the bushing is disposed in the middle of the boss; a material-stopping inclined surface is formed between the edge of the boss and the edge of the cutter head connecting seat.

[0011] Furthermore, the conveyor belt is provided with a first trimming cutter disc, a second trimming cutter disc, and a third trimming cutter disc at an upper spacing, and the rotation centers of the first trimming cutter disc, the second trimming cutter disc, and the third trimming cutter disc form the three vertices of a triangle.

[0012] The rotation centers of the first and second trimming cutter discs are distributed along the width direction of the conveyor belt on the same straight line. The distance between the two far-away endpoints of the first and second trimming cutter discs in the width direction of the conveyor belt is greater than the width of the large brick. The third trimming cutter disc is positioned between the first and second trimming cutter discs along the conveying direction of the conveyor belt. When the first, second, and third trimming cutter discs are projected horizontally onto a vertical plane, the two ends of the third trimming cutter disc along the width direction of the conveyor belt overlap with the two close ends of the first and second trimming cutter discs, respectively.

[0013] Furthermore, the rotation centers of the first, second, and third face trimmers form an isosceles triangle.

[0014] Furthermore, it also includes a flipping mechanism and a second cutting machine; both the flipping mechanism and the second cutting machine are installed on the production line conveyor, and the flipping mechanism is located downstream of the first cutting machine, and the second cutting machine is located downstream of the flipping mechanism.

[0015] Furthermore, a first positioning mechanism is provided upstream of the face-shaving mechanism, and a second positioning mechanism is provided between the face-shaving mechanism and the first cutting machine.

[0016] Secondly, a method for cutting foamed bricks, wherein the cutting method uses the aforementioned foamed brick cutting production line; the cutting method includes the following steps:

[0017] Large bricks are transported to the finishing mechanism via a conveyor belt. The finishing mechanism is controlled to finish the top of the large bricks, making the top of the large bricks flat.

[0018] The large bricks after finishing are transported to the first cutting machine via a conveyor belt. The first cutting machine is then controlled to cut the large bricks into several sheet-like bricks.

[0019] Furthermore, before the large bricks are transported to the finishing mechanism via the assembly line conveyor, the process further includes: placing the cast large bricks onto the assembly line conveyor, transporting the large bricks to the first positioning mechanism via the assembly line conveyor, and controlling the first positioning mechanism to position the large bricks.

[0020] Before the large bricks after surface finishing are transported to the first cutting machine via the assembly line conveyor, the method further includes: transporting the large bricks after surface finishing to the second positioning mechanism via the assembly line conveyor, and controlling the second positioning mechanism to position the large bricks after surface finishing.

[0021] After the first cutting machine cuts a large brick into several sheet bricks, the process further includes: conveying the cut sheet bricks to a flipping mechanism via a conveyor belt; controlling the flipping mechanism to flip the sheet bricks flat one by one; and conveying the flattened sheet bricks to a second cutting machine via a conveyor belt; controlling the second cutting machine to cut the sheet bricks into several small foamed bricks; and conveying the cut small foamed bricks to the next workstation via a conveyor belt.

[0022] By adopting the technical solution of the present invention, at least the following beneficial effects are achieved:

[0023] 1. By installing a finishing mechanism upstream of the first cutting machine, the top surface of the large brick can be leveled before it is transported to the first cutting machine. This effectively avoids unevenness at the end face of the smaller foamed bricks on top of the large brick due to unevenness of the top surface of the large brick, thus ensuring the quality of the smaller foamed bricks. At the same time, by leveling the top surface of the large brick in one go before cutting, compared with leveling each brick one by one later, production efficiency can be effectively improved.

[0024] 2. By using a bushing set in the middle of the top of the cutter head connecting seat, the output shaft of the drive motor is fixedly sleeved in the bushing, and the upper end of the bushing abuts against the bottom surface of the horizontal support structure. This can effectively ensure that the waste generated during the finishing process will not hit the output shaft of the drive motor, thereby helping to improve the service life of the drive motor.

[0025] 3. By designing a boss in the center of the top surface of the cutter head connecting seat, and forming a retaining slope between the boss and the edge of the cutter head connecting seat, the waste generated during the cutting and trimming of the top of large bricks will impact the retaining slope, thereby better breaking the waste into small particles. Under the centrifugal force of the rotation of the cutter head connecting seat, the broken waste is thrown outward, ensuring that the waste will not get stuck between the cutter head connecting seat and the horizontal support structure.

[0026] 4. The finishing mechanism is designed with three cutting discs—a first, a second, and a third—located above the conveyor belt. The rotation centers of these three discs form the three vertices of a triangle. When projected horizontally onto a vertical plane, the cutting discs are continuous and uninterrupted, effectively covering the entire top surface of the large brick, thus ensuring a smooth finish. The flatness of the top surface of the entire large brick is ensured; at the same time, the first, second and third trimming cutter discs are arranged in a triangular structure, which allows the first and second trimming cutter discs to trim the top surface of the large brick from both sides during the cutting process, while the third trimming cutter disc can trim the top surface of the large brick from the middle. Therefore, the waste material can be broken into multiple pieces during cutting. In addition, the inclined surface design of the cutter disc connecting seat can effectively break the waste material into small particles and throw them out.

[0027] 5. By setting a first positioning mechanism upstream of the finishing mechanism, the large brick can be accurately positioned to the required position before being transported to the finishing mechanism for finishing, thereby ensuring that the finishing mechanism can finish the top surface of the entire large brick; by setting a second positioning mechanism between the finishing mechanism and the first cutting machine, the large brick can be accurately positioned to the required position before being cut by the first cutting machine, thereby ensuring the cutting accuracy of the large brick by the first cutting machine.

Detailed Implementation Methods

[0051] To better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0053] Example 1

[0054] Please see Figures 1 to 13 As shown, a preferred embodiment of a foamed brick slitting production line 100 of the present invention includes a conveyor belt, a finishing mechanism 2, and a first cutting machine 3. Both the finishing mechanism 2 and the first cutting machine 3 are mounted on the conveyor belt, with the finishing mechanism 2 located upstream of the first cutting machine 3. In this invention, "upstream" refers to a position closer to the input end of the conveyor belt, while "downstream" refers to a position closer to the output end. When processing large bricks, the foamed brick slitting production line 100 first transports the large bricks to the finishing mechanism 2 for finishing via the conveyor belt, and then transports the finished large bricks to the first cutting machine 3 via the conveyor belt for slitting into sheet-shaped bricks.

[0055] This invention employs a finishing mechanism 2 located upstream of the first cutting machine 3. This allows the finishing mechanism 2 to level the top surface of the large brick before it is transported to the first cutting machine 3 for cutting. This effectively prevents unevenness in the top surface of the large brick, which would result in uneven end faces for the smaller foamed brick pieces located above the large brick after cutting, thus ensuring the quality of the smaller foamed brick pieces. Furthermore, by leveling the top surface of the large brick in one go before cutting, compared to leveling each brick individually later, production efficiency is significantly improved.

[0056] In a preferred embodiment of the present invention, please refer to the following: Figures 2 to 7As shown, the finishing mechanism 2 includes a support structure, several finishing cutter discs disposed above the conveyor belt, and several drive motors 23 fixed on the support structure. Each finishing cutter disc is on the same horizontal plane, specifically, the lower ends of each cutting cutter disc are on the same horizontal plane to ensure the flatness of the top surface of the large brick after finishing. During finishing, each finishing cutter disc can cover the top surface of the large brick to ensure flatness after finishing. Each finishing cutter disc is connected to the output end of a drive motor 23, so that the drive motor 23 outputs power to drive the finishing cutter disc to rotate and achieve finishing. In specific implementation, the height of the finishing cutter disc can be designed according to the height of the large brick, so that the finishing cutter disc can cut off a certain thickness from the top of the large brick (the specific thickness can be set according to actual needs). By designing the finishing mechanism 2 with multiple finishing cutter discs, this invention allows the waste material to be broken into multiple pieces during operation, enabling better crushing of the waste material.

[0057] In a specific implementation of the present invention, the support structure includes a horizontal support structure 21 and a vertical support structure 24. The horizontal support structure 21 is arranged above the assembly line conveyor along the width direction of the assembly line conveyor. Both ends of the horizontal support structure 21 are fixedly connected to both sides of the assembly line conveyor through the vertical support structure 24, so as to effectively support the trimming cutter discs and drive motors 23 using the horizontal support structure 21. Each trimming cutter disc is located below the horizontal support structure 21, and each drive motor 23 is fixed to the top of the horizontal support structure 21.

[0058] More specifically, the finishing mechanism 2 also includes a blade holder 25, on which the finishing blade is locked to the bottom surface of the blade holder 25. Each finishing blade is equipped with a blade holder 25, and the outer diameter of the finishing blade is larger than the outer diameter of the bottom surface of the blade holder 25, ensuring that the blade holder 25 will not affect the finishing of the finishing blade. A bushing 251 extends upward from the top center of the blade holder 25, and the output shaft of the drive motor 23 is fixedly sleeved in the bushing 251. The upper end of the bushing 251 abuts against the support structure, specifically against the bottom surface of the horizontal support structure 21. The present invention employs a bushing 251 set in the middle of the top of the cutter head connecting seat 25, and fixes the output shaft of the drive motor 23 inside the bushing 251, with the upper end of the bushing 251 abutting against the bottom surface of the horizontal support structure 21. This effectively ensures that the waste generated during the finishing process will not hit the output shaft of the drive motor 23, thereby helping to improve the service life of the drive motor 23.

[0059] More specifically, a boss 252 is formed in the middle of the top surface of the cutter head connecting seat 25, and the bushing 251 is disposed in the middle of the boss 252; a retaining slope 253 is formed between the edge of the boss 252 and the edge of the cutter head connecting seat 25. This invention, by designing a boss 252 in the middle of the top surface of the cutter head connecting seat 25 and a retaining slope 253 between the boss 252 and the edge of the cutter head connecting seat 25, ensures that when the finishing cutter head is cutting and finishing the top of a large brick, the waste generated from cutting will impact the retaining slope 253, thereby better breaking the waste into small particles. Under the centrifugal force of the rotation of the cutter head connecting seat 25, the broken waste is thrown outwards, ensuring that the waste does not get stuck between the cutter head connecting seat 25 and the horizontal support structure 21.

[0060] More specifically, above the assembly line conveyor (i.e. below the horizontal support structure 21), a first trimming cutter disc 221, a second trimming cutter disc 222, and a third trimming cutter disc 223 are provided at intervals, that is, three trimming cutter discs are provided, and the three trimming cutter discs do not contact each other. The rotation centers of the first trimming cutter disc 221, the second trimming cutter disc 222, and the third trimming cutter disc 223 form the three vertices of a triangle.

[0061] The rotation centers of the first trimming cutter disc 221 and the second trimming cutter disc 222 are distributed along the same straight line along the width direction of the conveyor. The distance between the two mutually distant endpoints of the first trimming cutter disc 221 and the second trimming cutter disc 222 in the width direction of the conveyor is greater than the width of the large brick, ensuring that the first trimming cutter disc 221 and the second trimming cutter disc 222 can cover both sides of the top surface of the large brick during trimming. The width direction of the conveyor refers to the direction perpendicular to the conveying direction, and the width of the large brick refers to the side length along the width direction of the conveyor. The side length along the conveying direction of the conveyor is the length of the large brick. The third... The finishing cutter disc 223 is positioned between the first finishing cutter disc 221 and the second finishing cutter disc 222 along the conveying direction of the assembly line conveyor. When the first finishing cutter disc 221, the second finishing cutter disc 222, and the third finishing cutter disc 223 are projected horizontally onto a vertical plane, the two ends of the third finishing cutter disc 223 along the width direction of the assembly line conveyor overlap with the two adjacent ends of the first finishing cutter disc 221 and the second finishing cutter disc 222, respectively. This ensures that the first finishing cutter disc 221, the second finishing cutter disc 222, and the third finishing cutter disc 223 can effectively cover the top surface of the entire large brick during finishing, thereby ensuring that the top surface of the entire large brick is flat after finishing.

[0062] This invention designs a finishing mechanism 2 comprising a first finishing cutter disc 221, a second finishing cutter disc 222, and a third finishing cutter disc 223 positioned above a conveyor belt. The rotation centers of these three discs form the three vertices of a triangle. Furthermore, when the first finishing cutter disc 221, the second finishing cutter disc 222, and the third finishing cutter disc 223 are projected horizontally onto a vertical plane, they are continuous and uninterrupted, effectively covering the entire top surface of a large brick. This ensures the flatness of the top surface of the entire large brick after finishing. At the same time, the first finishing cutter head 221, the second finishing cutter head 222, and the third finishing cutter head 223 are arranged in a triangular structure. This allows the first finishing cutter head 221 and the second finishing cutter head 222 to finish the top surface of the large brick from both sides during the cutting process, while the third finishing cutter head 223 can finish the top surface of the large brick from the middle. Therefore, the waste material can be broken into multiple pieces during cutting. Combined with the material-blocking inclined surface 253 design of the cutter head connecting seat 25, the waste material can be broken into small particles and thrown out.

[0063] Preferably, the rotation centers of the first face trimmer 221, the second face trimmer 222, and the third face trimmer 223 form an isosceles triangle.

[0064] More specifically, each of the finishing cutter discs (specifically including the first finishing cutter disc 221, the second finishing cutter disc 222, and the third finishing cutter disc 223) has a center with an assembly positioning through hole 224. The bottom of the cutter disc connecting seat 25 is provided with positioning protrusions 254 that are tightly fitted to the assembly positioning through holes 224. At the same time, a number of first locking through holes 225 are provided around the assembly positioning through holes 224 on the finishing cutter discs (specifically including the first finishing cutter disc 221, the second finishing cutter disc 222, and the third finishing cutter disc 223). The cutter disc connecting seat 25 is provided with a second locking through hole 255 corresponding to each of the first locking through holes 225. The cutter disc connecting seat 25 and the finishing cutter disc can be locked and fixed together by bolts and nuts (not shown). The finishing cutter discs have cutter heads evenly distributed in the circumferential direction to cut the top of large bricks.

[0065] More specifically, to ensure sufficient support strength for the horizontal support structure 21 and the vertical support structure 24, the horizontal support structure 21 includes a horizontal support plate 211, with first reinforcing ribs 212 fixedly attached to the top surface of the horizontal support plate 211 at its perimeter and center. The drive motor 23 is locked and fixed to the horizontal support plate 211. The vertical support structure 24 includes a vertical support plate 241, with second reinforcing ribs 242 fixedly attached to the outer perimeter and center of the vertical support plate 241. Simultaneously, during operation, the horizontal support plate 211 and the vertical support plate 241 can also block waste generated during the finishing process, preventing waste from flying outwards from the sides and top, thus ensuring production safety.

[0066] Preferably, the drive motor 23 is an asynchronous three-phase motor.

[0067] In a preferred embodiment of the present invention, the foamed brick slitting production line 100 further includes a flipping mechanism 4 and a second cutting machine 5; both the flipping mechanism 4 and the second cutting machine 5 are mounted on the production line conveyor, with the flipping mechanism 4 located downstream of the first cutting machine 3 and the second cutting machine 5 located downstream of the flipping mechanism 4. After the first cutting machine 3 cuts large bricks into sheet bricks, the sheet bricks are conveyed to the flipping mechanism 4 via the production line conveyor. The flipping mechanism 4 flips the sheet bricks one by one, and finally, the flipped sheet bricks are conveyed one by one to the second cutting machine 5 via the production line conveyor for cutting into small foamed bricks.

[0068] In a preferred embodiment of the present invention, a first positioning mechanism 6 is provided upstream of the finishing mechanism 2, and a second positioning mechanism 7 is provided between the finishing mechanism 2 and the first cutting machine 3. Since it is impossible to guarantee that the large brick is in an accurate position when it is placed on the conveyor belt, the first positioning mechanism 6 is provided upstream of the finishing mechanism 2. This allows the large brick to be accurately positioned to the required position before being conveyed to the finishing mechanism 2 for finishing, thus ensuring that the finishing mechanism 2 can flatten the top surface of the entire large brick. Simultaneously, since the large brick may slightly shift during the finishing process, the second positioning mechanism 7 is provided between the finishing mechanism 2 and the first cutting machine 3. This allows the large brick to be accurately positioned to the required position before being cut by the first cutting machine 3, thus ensuring the cutting accuracy of the large brick by the first cutting machine 3.

[0069] For more specific details, please refer to the following: Figure 8As shown, the first positioning mechanism 6 includes a first roller 61, a first telescopic cylinder 62, and a first push block 63; the conveyor belt is provided with a first support frame 64 and a second support frame 65 on both sides respectively. A plurality of first rollers 61 are arranged on the upper end of the first support frame 64 along the conveying direction, and each first roller 61 is rotatably mounted on the first support frame 64 on the side close to the second support frame 65 in the vertical direction; the first telescopic cylinder 62 is fixed to the upper end of the second support frame 65, and the movable end of the first telescopic cylinder 62 is fixedly connected to the first push block 63. The first push block 63 is located inside the second support frame 65, that is, on the side close to the first support frame 64; preferably, the first telescopic cylinder 62 can be a hydraulic cylinder or a pneumatic cylinder. During positioning, the first telescopic cylinder 62 drives the first push block 63 to move forward. The first push block 63 pushes the large brick that is conveyed between the first roller 61 and the first push block 63 forward, so that one side of the large brick is close to the first roller 61, thereby achieving the positioning of the large brick. After positioning is completed, the first telescopic cylinder 62 drives the first push block 63 to retract backward, and the assembly line conveyor conveys the positioned large brick to the finishing mechanism 2.

[0070] For more specific details, please refer to the following: Figure 9 As shown, the second positioning mechanism 7 includes a second roller 71, a second telescopic cylinder 72, and a second push block 73; a third support frame 74 and a fourth support frame 75 are respectively provided on both sides of the assembly line conveyor. Several second rollers 71 are arranged along the conveying direction on the upper end of the third support frame 74, and each second roller 71 is rotatably arranged on the third support frame 74 on the side close to the fourth support frame 75 in the vertical direction; the second telescopic cylinder 72 is fixed to the upper end of the fourth support frame 75, and the movable end of the second telescopic cylinder 72 is fixedly connected to the second push block 73. The second push block 73 is located inside the fourth support frame 75, that is, on the side close to the third support frame 74. During positioning, the second telescopic cylinder 72 drives the second push block 73 to move forward. The second push block 73 pushes the large brick that is conveyed between the second roller 71 and the second push block 73 forward, so that one side of the large brick is close to the second roller 71, thereby achieving positioning of the large brick. After positioning is completed, the second telescopic cylinder 72 drives the second push block 73 to retract backward, and the assembly line conveyor conveys the positioned large brick to the first cutting machine 3.

[0071] In a preferred embodiment of the present invention, the assembly line conveyor includes a first conveyor 11, a second conveyor 12, a third conveyor 13, a fourth conveyor 14, a fifth conveyor 15, a corner transition conveyor 16, a sixth conveyor 17, and a seventh conveyor 18 arranged sequentially along the assembly line; wherein the second conveyor 12, the fourth conveyor 14, and the seventh conveyor 18 are all belt conveyors, and the first conveyor 11, the third conveyor 13, the fifth conveyor 15, and the sixth conveyor 17 are all roller conveyors;

[0072] The first positioning mechanism 6 is located above the output end of the first conveyor 11, the surface trimming mechanism 2 is located above the second conveyor 12, and the second positioning mechanism 7 is located above the third conveyor 13. The first cutting machine 3 is located above the fourth conveyor 14 to cut the large bricks conveyed on the fourth conveyor 14. The fifth conveyor 15 is perpendicular to the corner transition conveyor 16, which can convey the sheet bricks to the flipping mechanism 4 in a direction perpendicular to the fifth conveyor 15. The flipping mechanism 4 is located at the input end of the sixth conveyor 17 to flip the cut sheet bricks one by one onto the sixth conveyor 17. The second cutting machine 5 is located above the seventh conveyor 18 to cut the sheet bricks conveyed on the seventh conveyor 18.

[0073] In a preferred embodiment of the present invention, please refer to the following: Figure 11 As shown, the corner transition conveyor 16 includes a transition frame 161, a lifting assembly 162, and a transition conveyor roller group 163;

[0074] The transition frame 161 is positioned close to the output end of the fifth conveyor 15. The transition frame 161 spans the fifth conveyor 15 along its width direction, and the upper end of the transition frame 161 is lower than the upper end of the fifth conveyor 15, allowing the sheet bricks output from the fifth conveyor 15 to smoothly enter the transition frame 161. The lifting assembly 162 is positioned within the transition frame 161 corresponding to the output end of the fifth conveyor 15. The transition conveying roller group 163 is positioned above the lifting assembly 162. A baffle plate 164 is provided on the side of the transition frame 161 away from the output end of the fifth conveyor 15. The pushing assembly (not shown) is provided at the end of the transition frame 161 away from the flipping mechanism 4. In operation, when the slit brick pieces are conveyed to the fifth conveyor 15, the lifting assembly 162 drives the transition conveyor roller group 163 to rise, so that the top of the transition conveyor roller group 163 is level with the top of the fifth conveyor 15. The fifth conveyor 15 then conveys the slit brick pieces forward, allowing them to enter the top of the transition conveyor roller group 163. During this process, the baffle plate 164 blocks the slit brick pieces, preventing them from falling. After all the slit brick pieces from a large brick have been conveyed to the top of the transition conveyor roller group 163, the lifting assembly 162 drives the transition conveyor roller group 163 to descend back to its original position. At the same time, the pushing assembly pushes the slit brick pieces at the top of the transition conveyor roller group 163 towards the flipping mechanism 4, allowing the slit brick pieces to enter the flipping mechanism 4 one by one.

[0078] Example 2

[0079] Please see Figures 1 to 13As shown, this invention provides a method for cutting foamed bricks. The cutting method uses the aforementioned foamed brick cutting production line 100. For the specific structure of the foamed brick cutting production line 100, please refer to the detailed description in Embodiment 1, which will not be repeated here. The cutting method includes the following steps:

[0080] Step S1: The large brick is conveyed to the finishing mechanism 2 by the assembly line conveyor. The finishing mechanism 2 is controlled to finish the top of the large brick to form a flat surface. This can ensure the quality of the small foamed bricks that are cut later.

[0081] Step S2: The large bricks after surface finishing are transported to the first cutting machine 3 by the assembly line conveyor, and the first cutting machine 3 is controlled to cut the large bricks into several pieces.

[0082] This invention employs a finishing mechanism 2 to level the top of the large brick before cutting it, effectively preventing unevenness in the end faces of the smaller foamed bricks located on top of the large brick after cutting, thus ensuring the quality of the smaller foamed bricks. Furthermore, by leveling the top of the large brick in one go before cutting, compared to leveling each brick individually later, production efficiency is significantly improved.

[0083] In a preferred embodiment of the present invention, before the large bricks are conveyed to the finishing mechanism 2 by the assembly line conveyor, the method further includes:

[0084] Step S0: Place the cast brick onto the assembly line conveyor. The assembly line conveyor transports the brick to the first positioning mechanism 6. The first positioning mechanism 6 is controlled to position the brick so that when the brick enters below the finishing mechanism 2, the finishing mechanism 2 can accurately finish the top of the brick without the brick being unable to finish the top of the brick completely due to excessive offset.

[0085] Before the large, finished bricks are conveyed to the first cutting machine 3 via the assembly line conveyor, the process also includes:

[0086] Step S21: The large bricks after surface finishing are transported to the second positioning mechanism 7 by the assembly line conveyor. The second positioning mechanism 7 is controlled to position the large bricks after surface finishing, so that when the large bricks enter the lower part of the first cutting machine 3, the first cutting machine 3 can accurately cut the large bricks, and there will be no situation where the first cutting machine 3 cannot accurately cut the large bricks due to excessive deviation of the large bricks.

[0087] After the first cutting machine is used to cut a large brick into several sheet-like bricks, the method further includes:

[0088] Step S3: The cut sheet bricks are conveyed to the flipping mechanism 4 via a conveyor belt. The flipping mechanism 4 flips the cut sheet bricks 90° to facilitate further cutting. The flipping mechanism 4 is controlled to flip the sheet bricks flat one by one and conveys them to the second cutting machine 5 via the conveyor belt. The second cutting machine 5 is controlled to cut the sheet bricks into several small foamed bricks. The small foamed bricks are conveyed to the next workstation via the conveyor belt for further processing.

[0089] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
