Description

Technical Field

[0001] This invention belongs to the field of ceramic technology, specifically relating to a method for rapidly cutting brick dividing lines and cutting bricks. Background Technology

[0002] Most existing ceramic cutting lines adopt the form of sawing the top and then clamping the bogie. The process is that after the ceramic is sawn and cut, the cut surfaces of the two bricks are aligned on the same side by clamping and rotating. Then, the bricks are pushed to merge and enter the subsequent edge grinding process. This method reduces the production cost of small-sized ceramic tiles and improves production efficiency. Taking sawing the top of ceramic tiles as an example, the fastest production speed of this step currently reaches 30 pieces / min.

[0003] With technological advancements, the industry has placed higher demands on the brick cutting and splitting process, requiring faster processing speeds and higher work efficiency to increase production capacity. However, the existing production process for sawing, cutting, and then clamping the bogie is insufficient to meet these higher output requirements. This is mainly due to the limitations of the clamping and turning misalignment process. The working speed of the clamping and turning misalignment process is relatively slow compared to other stages, making it difficult to improve the overall production speed. For example, in patent CN2018116486785, a foam ceramic cutting production line uses a turning machine to turn ceramic bricks. Obviously, this turning machine is separate from the preceding and following equipment. If the efficiency of the turning machine is not improved, the overall production efficiency will also be difficult to increase.

[0004] Based on this, the present invention aims to provide a production line for rapid brick cutting and splitting, thereby improving the overall production efficiency of the line. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the purpose of this invention is to provide a rapid brick-cutting line and a method for cutting and separating bricks, thereby solving the bottleneck of production output, improving the overall production efficiency of the production line, and enabling the fastest production speed of sawing and cutting to reach 50 pieces / min.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides a method for rapidly cutting brick dividing lines, comprising:

[0008] The sawing and cutting module is used to form stress lines on the top surface of ceramic tiles and cut along the stress lines to form two ceramic tiles side by side.

[0009] The steering module includes a second frame and a steering conveying assembly, a main conveying assembly, and a transfer device disposed within the second frame. The main conveying assembly is connected to the sawing and cutting module. The transfer device is disposed between the main conveying assembly and the steering conveying assembly. Transfer devices are disposed at both the front and rear of the steering conveying assembly. One end of the transfer device is connected to one end of the steering conveying assembly, and the other end of the transfer device is connected to the main conveying assembly.

[0010] Preferably, the steering and conveying assembly includes an auxiliary conveying mechanism and a differential steering mechanism;

[0013] More preferably, the number of differential steering mechanisms is greater than or equal to one; more preferably, the number of differential steering mechanisms is two.

[0014] Preferably, the steering conveyor assembly is disposed above the main conveyor assembly;

[0015] The second frame includes an upper frame and a lower frame. The upper frame is located above the lower frame. The steering conveyor assembly is located on the upper frame. The main conveyor assembly is located on the lower frame. The top end of the transfer device is connected to one end of the steering conveyor assembly, and the bottom end of the transfer device is connected to the main conveyor assembly.

[0016] More preferably, the transfer device includes a movable support, a lifting cylinder, and a guide conveyor belt. The top end of the movable support is movably connected to the upper support, and the bottom end of the movable support is above the lower support. The lifting cylinder is located outside the lower support, and the piston of the lifting cylinder is hinged to the bottom end of the movable support. The guide conveyor belt is located inside the movable support, and the top end of the guide conveyor belt is connected to one end of the steering conveyor assembly. The bottom end of the guide conveyor belt enters the main conveyor assembly.

[0017] More preferably, the movable support includes a fixed rod, a bottom rod, a connecting rod, and a support rod. The two ends of the fixed rod are rotatably connected to the upper frame. The bottom rod is located above the main conveying assembly. The bottom rod is parallel to the fixed rod, and the bottom rod and the fixed rod are connected and fixedly connected by the connecting rod. The end of the bottom rod is hinged to the piston of the lifting cylinder. The support rod is disposed between the bottom rod and the fixed rod, and the support rod is parallel to the bottom rod. The two ends of the support rod are fixedly connected to the connecting rod.

[0018] The guide conveyor belt includes a fixed wheel, a movable wheel, a belt, and a belt frame. The fixed wheel and the movable wheel are rotatably disposed at both ends of the belt frame. The belt is sleeved on the fixed wheel and the movable wheel. The fixed wheel is sleeved on a fixed rod and is rotatably connected to the fixed rod. The bottom rod and the support rod pass through the belt frame and are both fixedly connected to the belt frame.

[0019] Preferably, the main conveying assembly includes a feeding conveying mechanism, a main conveying mechanism, and a discharging conveying mechanism connected end to end. The feeding conveying mechanism is connected to the sawing and cutting module. One of the transfer devices connects the feeding conveying mechanism to the front end of the turning conveying assembly, and another transfer device connects the discharging conveying mechanism to the rear end of the turning conveying assembly.

[0020] Preferably, the rapid brick-cutting line further includes a brick-pushing module, which includes a third frame and a second conveying device and a brick-pushing mechanism disposed within the third frame. The second conveying device is connected to the main conveying assembly, and the brick-pushing mechanism is disposed on the second conveying device.

[0021] More preferably, the brick pushing mechanism includes a brick pushing bracket, a brick pushing cylinder, and a brick pushing wheel assembly. The brick pushing bracket is mounted on the second conveying device. The two brick pushing cylinders are located on both sides of the second conveying device and are fixedly connected to the brick pushing bracket. The piston of the brick pushing cylinder is connected to the brick pushing wheel assembly, and the brick pushing wheel assembly is parallel to the conveying direction of the second conveying device.

[0022] Preferably, the sawing and cutting module includes a first frame and a first conveying device, a sawing mechanism and a cutting mechanism disposed within the first frame, wherein the sawing mechanism is located in front of the cutting mechanism along the feeding direction.

[0023] Preferably, the rapid brick-cutting line further includes a front-mounted conveying module, which is located in front of the sawing and cutting module and is connected to the first conveying device.

[0024] In a second aspect, the present invention proposes a method for cutting and separating bricks, as follows:

[0025] (1) The whole ceramic tile enters the sawing and cutting module. First, stress lines are drawn on the top surface of the ceramic tile. Then, the ceramic tile is cut to form two ceramic tiles side by side. The two ceramic tiles move forward in the sawing and cutting module at the same speed.

[0026] (2) Two ceramic bricks enter the main conveying component of the steering module. One of the ceramic bricks enters the steering conveying component along the transfer device and achieves a 180° turn in the transfer device. At the same time, the other ceramic brick continues to move forward along the main conveying component. The two ceramic bricks move at different speeds. When one of the ceramic bricks completes the turn, it returns to the main conveying component along the other transfer device and moves forward in a staggered manner with the other ceramic brick.

[0027] (3) Ceramic bricks that do not need to be turned and ceramic bricks that have been turned enter the brick pushing module. The two ceramic bricks are pushed to the center area of ​​the brick pushing module respectively, and then the two ceramic bricks continue to move forward in the same straight line to enter the subsequent processing steps.

[0028] Beneficial effects:

[0029] This invention integrates the segmentation and splitting of ceramic tiles onto a single production line. During forward transport, the ceramic tiles are turned and aligned in the subsequent tile-pushing module, allowing two ceramic tiles to merge for the subsequent edge-grinding process.

[0030] This invention solves the problem that existing equipment has a slow turning speed for ceramic bricks, which cannot keep up with the efficiency of other equipment. The production speed of the rapid brick cutting line can even reach 50 pieces / min, which matches the efficiency of the preceding and following processes. The overall automation level of the production line is high, saving labor costs and greatly improving production efficiency and product qualification rate. Attached Figure Description

[0058] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0059] like Figure 1-13 As shown, this invention proposes a rapid brick-cutting line, comprising a sawing and cutting module 1 and a turning module 2. In this invention, the turning module 2 serves both turning and transport functions. The ceramic bricks are divided into two parallel sections in the sawing and cutting module 1. After entering the turning module 2, the two sections of ceramic bricks advance at different speeds, with one side of the ceramic bricks completing the turning process while the other side continues in its original state. Ultimately, the ceramic bricks, originally arranged side-by-side, are transformed into a staggered arrangement, advancing towards subsequent processes. The technical solution of this invention will be described in detail below with a specific structural description.

[0060] In this invention, the sawing and cutting module 1 can be an existing sawing and cutting device, whose function is to divide the ceramic tile into two parallel parts as evenly as possible. This invention also proposes a feasible structure for the sawing and cutting module 1, as follows:

[0061] like Figure 2 As shown, the sawing and top-breaking module 1 includes a first frame 13, a first conveying device 14, and a sawing mechanism 11 and a top-breaking mechanism 12 arranged sequentially in the first frame 13. The sawing mechanism 11 is located above the first conveying device 14, and the top-breaking mechanism 12 is located below the first conveying device 14. After the sawing mechanism 11 scratches stress lines on the top surface of the ceramic tile, the top-breaking mechanism 12 applies force to the ceramic tile, causing the ceramic tile to be divided into two parts along the stress lines.

[0062] Preferably, the first conveying device 14 is a conveyor belt device, which has multiple parallel conveyor belts inside. The top-breaking mechanism 12 is arranged between the parallel conveyor belts, and the ceramic bricks are placed on the conveyor belt device for conveying. It is easy to understand that the first conveying device 14 can also be a conveying device of other structures, such as a chain conveyor device, as long as it can cooperate with the top-breaking mechanism 12.

[0063] Specifically, the sawing mechanism 11 includes a saw blade 111 and a sawing lifting device 112. The sawing lifting device 112 is mounted on the first frame 13, and the saw blade 111 is connected to the sawing lifting device 112, with the saw blade 111 arranged along the conveying direction of the first conveying device 14. The sawing lifting device 112 can be a motor lifting device, a hydraulic lifting device, or a saw blade cylinder.

[0064] Taking the sawing lifting device 112, which is a scribing cylinder, as an example, specifically, the number of scribing cylinders is greater than or equal to two. With two scribing cylinders as an example, the cylinder bodies of the two scribing cylinders are mounted on the first frame 13. The pistons of the two scribing cylinders are fixedly connected to the top surfaces of the front and rear ends of the scribing blade 111, respectively. When stress lines need to be drawn, the scribing cylinders lower the scribing blade 111 to contact the top surface of the ceramic tile. As the ceramic tile moves forward, the scribing blade 111 forms stress lines on the top surface of the ceramic tile. It is easy to understand that when the scribing blade 111 does not lower, stress lines are not formed on the surface of the ceramic tile, and the first conveying device 14 directly drives the ceramic tile forward.

[0065] Preferably, the sawing mechanism 11 further includes an upper limit wheel set 113 and a side limit wheel set 114. Multiple upper limit wheel sets 113 are disposed above the first conveying device 14, and two side limit wheel sets 114 are respectively disposed on both sides of the first conveying device 14. It is easy to understand that the function of the upper limit wheel set 113 and the side limit wheel set 114 is to restrict the position of the ceramic tile. Used in conjunction with the saw blade 111, during the process of drawing stress lines, the upper limit wheel set 113 contacts the top surface of the ceramic tile, and the side limit wheel set 114 contacts the side surface of the ceramic tile. Therefore, as the ceramic tile moves forward, the saw blade 111 can more easily draw stress lines on the top surface of the ceramic tile.

[0066] It is easy to understand that the side limiting wheel set 114 can be used in conjunction with the centering cylinder. After the ceramic tile enters the area of ​​the side limiting wheel set 114, the centering cylinders on both sides are activated to center the ceramic tile, which facilitates subsequent marking.

[0067] The breaking mechanism 12 includes a breaking lifting device and a breaking wheel assembly 121. The breaking lifting device is located below the first conveying device 14, and the breaking wheel assembly 121 is located on the breaking lifting device. The breaking lifting device drives the breaking wheel assembly 121 to contact the bottom surface of the ceramic tile, causing the ceramic tile to be divided into left and right parts along the stress line. The breaking lifting device can be a motor-driven lifting device, a hydraulic lifting device, or a breaking cylinder.

[0068] The top-breaking wheel assembly 121 is preferably a single-row wheel assembly, and more preferably, the top-breaking wheel assembly 121 and the scriber 111 are both arranged along the axis of the first conveyor belt.

[0069] Taking the top-breaking lifting device as an example, specifically, the number of top-breaking cylinders is greater than or equal to two. Taking two top-breaking cylinders as an example, the cylinder bodies of the two top-breaking cylinders are connected to the first frame 13, and the pistons of the two top-breaking cylinders are respectively connected to the bottom surface of the top-breaking wheel assembly 121. The top-breaking cylinders control the top-breaking wheel assembly 121 to rise and apply force to the bottom surface of the ceramic tile, so that the ceramic tile is divided into two parts along the stress line.

[0070] Furthermore, the top-breaking mechanism 12 also includes upper limit positioning members 122 that cooperate with the top-breaking wheel assembly 121. The two upper limit positioning members 122 are located above the first conveying device 14 and on both sides of the top-breaking wheel assembly 121. When the top-breaking wheel assembly 121 rises and applies force to the ceramic tile, the top surface of the ceramic tile contacts the two upper positioning members, and the ceramic tile cannot continue to rise. At this time, the two upper positioning members are on both sides of the stress line, and the top-breaking wheel assembly 121 continues to apply force, and the ceramic tile is divided into two parts along the stress line.

[0071] As is easy to understand, the sawing and cutting module is also equipped with multiple photoelectric proximity switches to sense the position of the ceramic tile within the sawing and cutting module 1.

[0072] Furthermore, the rapid brick-cutting line may also include a front conveyor module 4, which is located before the sawing and cutting module 1 and is connected to the first conveying device 14. Preferably, the front conveyor module 4 can be a conveyor belt device. More preferably, centering guide wheel sets 41 are provided on both sides of the front conveyor module 4, and the centering guide wheel sets 41 on both sides are located at the end of the front conveyor module 4 that is connected to the first conveying device 14, such as... Figure 1 As shown, the centering guide wheel group 41 on both sides contacts the two sides of the ceramic tile, and after adjusting the position of the ceramic tile, the ceramic tile enters the sawing and cutting module 1.

[0073] like Figure 9 As shown, after the ceramic tile is broken off, two bricks are formed side by side. On the first conveying device 14 of the sawing and breaking module 1, the two ceramic bricks move forward side by side.

[0074] like Figure 3-8As shown, the steering module 2 includes a second frame 24 and a steering conveying assembly 22, a main conveying assembly 21 and a transfer device 23 disposed within the second frame 24. The main conveying assembly 21 is connected to the first conveying device 14. The transfer device 23 is disposed between the main conveying assembly 21 and the steering conveying assembly 22. The transfer device 23 is disposed at both the front and rear of the steering conveying assembly 22. One end of the transfer device 23 is connected to one end of the steering conveying assembly 22, and the other end of the transfer device 23 is connected to the main conveying assembly 21.

[0075] The transfer device 23 can take various forms. For example, it can be a conveyor belt, a robotic arm, or a gripper transfer device, etc., as long as the transfer device 23 achieves the effect of transferring ceramic bricks from the main conveying assembly 21 to the turning conveying assembly 22. Preferably, the transfer device 23 is a common conveyor belt.

[0076] Taking the two ceramic bricks formed after the top-breaking ceramic brick as the left brick and the right brick respectively as an example, the left brick and the right brick enter the main conveying assembly 21 from the first conveying device 14 at the same speed. The right brick enters the turning conveying assembly 22 along the first transfer device 23, turns in the turning conveying assembly 22, and returns to the main conveying assembly 21 along the second transfer device 23. At the same time, the left brick continues to move forward along the main conveying assembly 21. The forward speed of the left brick and the right brick is different. After the right brick turns and enters the main conveying assembly 21, it continues to move forward on the main conveying assembly 21 with the left brick in front and the right brick behind, and enters the subsequent process.

[0077] It is easy to understand that the overall transport length of the main conveying component 21 is greater than the overall transport length of the turning conveying component 22. Since the ceramic bricks cannot move forward normally during the turning process, the average speed of the ceramic bricks that need to be turned is lower than the average speed of the ceramic bricks that are moving normally. In the end, the ceramic bricks that do not need to be turned normally and the ceramic bricks that have been turned move forward in a front-back manner.

[0078] In this invention, the arrangement of the main conveying assembly 21 and the steering conveying assembly 22 can be varied, and the two transfer devices 23 serve to connect the main conveying assembly 21 and the steering conveying assembly 22.

[0079] To shorten unnecessary transport distances, the main conveying assembly 21 and the steering conveying assembly 22 are preferably arranged in parallel. For example, the steering conveying assembly 22 is located on one side of the main conveying assembly 21 (not shown in the attached figure). More preferably, for a more compact overall structure of the steering module 2, the present invention preferably places the steering conveying assembly 22 above the main conveying assembly 21. The second frame 24 includes an upper frame 223 and a lower frame 214. The upper frame 223 is located above the lower frame 214. The steering conveying assembly 22 is located on the upper frame 223, and the main conveying assembly 21 is located on the lower frame 214. The top end of the transfer device 23 is connected to one end of the steering conveying assembly 22, and the bottom end of the transfer device 23 is connected to the main conveying assembly 21. More preferably, the transfer device 23 is located on one side of the main conveying assembly 21, between two adjacent ceramic bricks inside the main conveying assembly 21. One ceramic brick will move upward along the transfer device 23 into the steering conveying assembly 22, while the other ceramic brick continues to move forward along the main conveying assembly 21.

[0080] In this invention, the structure of the steering and conveying assembly 22 can be varied. It can be a combination of existing common steering and conveying structures, such as the combination of a conveyor belt and a steering structure. The steering structure can also be varied.

[0081] Preferably, the present invention proposes a feasible steering and conveying assembly 22 structure, which realizes the steering of ceramic bricks through differential steering. The overall structure of the steering and conveying assembly 22 is more compact, and it realizes the transportation function during the steering process. Figure 3-8 As shown, the steering and conveying assembly 22 includes an auxiliary conveying mechanism 221 and a differential steering mechanism 222. The front and rear ends of the auxiliary conveying mechanism 221 are respectively connected to a transfer device 23. The differential steering mechanism 222 includes two side conveyor belts 2221, which are arranged on both sides of the auxiliary conveying mechanism 221, and the top surfaces of the two side conveyor belts 2221 are higher than the top surface of the auxiliary conveying mechanism 221.

[0082] Combination Figure 3-8 It is known that each side conveyor belt 2221 is driven by an independent motor 2222. Therefore, within the same differential steering mechanism 222, the speeds of the two side conveyor belts 2221 can be different. When a ceramic brick enters a differential steering mechanism 222, the speed difference between the two side conveyor belts 2221 causes the ceramic brick to rotate at a certain angle, thus achieving forward transport during the steering process. It is easy to understand that the speed difference between the two side conveyor belts 2221 is actually a comparison of their speeds. For example, the speed of one side conveyor belt 2221 can be zero, and even the rotation directions of the two side conveyor belts 2221 can be opposite.

[0083] The number of differential steering mechanisms 222 is greater than or equal to one. Each time a ceramic tile passes a differential steering mechanism 222, it can rotate a certain angle. The number and arrangement of the differential steering mechanisms 222 are determined based on the design of the rotation angle. It is easy to understand that the purpose of this invention is to rotate one side of the ceramic tile by 180°, so that its cross-section faces the same direction as the cross-section of the other side. Taking a differential steering mechanism 222 rotating the ceramic tile by 90° as an example, at least two differential steering mechanisms 222 need to be installed within the steering and conveying assembly 22.

[0084] Preferably, the auxiliary conveying mechanism 221 is provided with first limiting guide wheel groups 224 on both sides of its rear end. The first limiting guide wheel groups 224 are located outside the differential steering mechanism 222. The rear half of the differential steering mechanism 222, which is located outside the rear end of the auxiliary conveying mechanism 221, is located between the two first limiting guide wheel groups 224. When the ceramic brick turns for the second time, the first limiting guide wheel groups 224 have a limiting effect on the ceramic brick, guiding the ceramic brick from the auxiliary conveying mechanism 221 into the transfer device 23.

[0085] Preferably, the auxiliary conveying mechanism 221 can also be a conveyor belt device. The present invention does not impose specific limitations on the auxiliary conveying mechanism 221.

[0086] In this invention, the main conveying assembly 21 can take various forms, as long as it is a device that can transport ceramic bricks forward. Preferably, the main conveying assembly 21 is a conveyor belt device. The main conveying assembly 21 includes a feeding conveying mechanism 211, a main conveying mechanism 212, and a discharging conveying mechanism 213 connected end to end. The feeding conveying mechanism 211 is connected to the first conveying device 14. A transfer device 23 connects the feeding conveying mechanism 211 to the front end of the auxiliary conveying mechanism 221, and another transfer device 23 connects the discharging conveying mechanism 213 to the rear end of the auxiliary conveying mechanism 221.

[0087] Preferably, a second limiting guide wheel assembly 2121 is provided at both the front and rear ends of the main conveying mechanism 212, and the second limiting guide wheel assembly 2121 is located on the outside of the main conveying mechanism 212. Specifically, the second limiting guide wheel assembly 2121 is provided on both sides of the front end of the main conveying mechanism 212 that connects with the feeding conveying mechanism 211 to guide the ceramic bricks from the feeding conveying mechanism 211 into the main conveying mechanism 212, and the second limiting guide wheel assembly 2121 is provided on both sides of the rear end of the main conveying mechanism 212 that connects with the discharge conveying mechanism 213 to guide the ceramic bricks from the main conveying mechanism 212 into the discharge conveying mechanism 213.

[0088] More preferably, a third limit guide wheel group 2131 is provided on both sides of the discharge conveying mechanism 213.

[0089] The present invention also proposes a feasible structure for the transfer device 23, as follows:

[0090] The transfer device 23 includes a movable support, a lifting cylinder 235, and a guide conveyor belt, such as Figure 4 As shown, the top of the movable support is movably connected to the upper support, and the bottom of the movable support is above the lower support. The lifting cylinder 235 is located on the outside of the lower support, and the piston of the lifting cylinder 235 is hinged to the bottom of the movable support. The guide conveyor belt is located inside the movable support, and the top of the guide conveyor belt is connected to one end of the auxiliary conveying mechanism 221. The bottom of the guide conveyor belt enters the feeding conveying mechanism 211 or the discharging conveying mechanism 213.

[0091] It is easy to understand that the bottom end of the cylinder body of the lifting cylinder 235 is hinged to the side of the lower support, and the piston of the lifting cylinder 235 is hinged to the movable support. Since the top end of the movable support is rotatably connected to the upper support, the lifting cylinder 235 drives the bottom end of the movable support to rise and fall, thereby driving the bottom end of the guide conveyor belt to enter or move away from the main conveyor assembly 21.

[0092] The transfer device 23 and the main conveying assembly 21 can be connected or disconnected via the lifting cylinder 235. When the transfer device 23 is connected to the main conveying assembly 21, the steering conveying assembly 22 is engaged, steering one of the ceramic bricks formed by the breakage, thereby achieving that the cross-sections of the two ceramic bricks are in the same direction and the two ceramic bricks move forward in a front-and-back manner. When the transfer device 23 is disconnected from the main conveying assembly 21, the steering conveying assembly 22 is not used, and the main conveying assembly 21 normally conveys ceramic bricks that have not been sawn and broken, or normally conveys the two ceramic bricks formed by the breakage.

[0093] Furthermore, the guide conveyor belt can be equipped with its own power source, or it can be without a power source.

[0094] like Figure 4 As shown, the movable support includes a fixed rod 231, a bottom rod 232, a connecting rod 233, and a support rod 234. Both ends of the fixed rod 231 are rotatably connected to the upper frame 223. The bottom rod 232 is positioned above the main conveying assembly 21, parallel to the fixed rod 231, and is fixedly connected to the fixed rod 231 via the connecting rod 233. The end of the bottom rod 232 is hinged to the piston of the lifting cylinder 235. The support rod 234 is positioned between the bottom rod 232 and the fixed rod 231, parallel to the bottom rod 232, and both ends of the support rod 234 are fixedly connected to the connecting rod 233. The lifting cylinder 235 drives the bottom rod 232 to rise and fall, thereby causing the movable support to rotate about the fixed rod 231 as an axis.

[0095] The guide conveyor belt includes a fixed wheel 236, a movable wheel 237, a belt 239, and a belt frame 238. The fixed wheel 236 and the movable wheel 237 are rotatably mounted at both ends of the belt frame 238. The belt 239 is fitted onto the fixed wheel 236 and the movable wheel 237. The fixed wheel 236 is fitted onto a fixed rod 231, and the fixed wheel 236 and the fixed rod 231 are rotatably connected. The bottom rod 232 and the support rod 234 pass through the belt frame 238, and both the bottom rod 232 and the support rod 234 are fixedly connected to the belt frame 238.

[0096] like Figure 4 As shown, the lifting cylinder 235 drives the bottom end of the guide conveyor belt to descend into the main conveyor assembly 21, and the movable wheel 237 of the guide conveyor belt is located inside the main conveyor assembly 21. Taking the ceramic brick entering the steering conveyor assembly 22 as an example, when the ceramic brick moves to the position of the movable wheel 237, the ceramic brick will move upward along the belt 239 to the end of the auxiliary conveyor mechanism 221. After the auxiliary conveyor mechanism 221 contacts the ceramic brick, it drives the ceramic brick into the auxiliary conveyor mechanism 221. It is easy to understand that the length of the ceramic brick along the conveying direction is greater than the conveying distance of the guide conveyor belt. The ceramic brick has already entered the steering conveyor assembly 22 before it has completely left the main conveyor assembly 21. Similarly, when the ceramic brick leaves the steering conveyor assembly 22, it has already entered the main conveyor assembly 21 before it has completely left the steering conveyor assembly 22.

[0097] like Figure 4 As shown, there are two or more guide conveyor belts located on one side inside the main conveying assembly 21, serving only to transfer ceramic bricks on one side. In this invention, the position of the guide conveyor belts within the movable support can be adjusted. Since the guide conveyor belts are only connected to the bottom rod 232 and support rod 234 of the movable support via the belt frame 238, the belt frame 238 can be moved to the other side of the movable support and then fixedly connected to the bottom rod 232 and support rod 234. It is easy to understand that the guide conveyor belts need to cooperate with the transfer conveying assembly. When the position of the guide conveyor belts is adjusted, the positions of the auxiliary conveying mechanism 221 and the differential steering mechanism 222 within the transfer conveying assembly are also adjusted accordingly. This allows for the selection of ceramic bricks on the other side for steering.

[0098] Multiple photoelectric proximity switches are also installed in the steering module 2 to sense the position of the ceramic bricks within the steering module 2.

[0099] In this invention, the rapid brick-cutting line also includes a brick-pushing module 3. The brick-pushing module 3 includes a third frame 33 and a second conveying device 31 and a brick-pushing mechanism 32 disposed within the third frame 33. The second conveying device 31 is connected to the main conveying assembly 21. The brick-pushing mechanism 32 is disposed on the second conveying device 31. Specifically, the brick-pushing mechanism 32 includes a brick-pushing bracket 321, a brick-pushing cylinder 322, and a brick-pushing wheel assembly 323. The brick-pushing bracket 321 is disposed on the second conveying device 31. The two brick-pushing cylinders 322 are located on both sides of the second conveying device 31 and are fixedly connected to the brick-pushing bracket 321. The piston of the brick-pushing cylinder 322 is connected to the brick-pushing wheel assembly 323. The brick-pushing wheel assembly 323 is parallel to the conveying direction of the second conveying device 31.

[0100] like Figure 9-10 As shown, the two ceramic bricks leave the steering module 2 in a staggered manner, one in front of the other. They are positioned on the left and right sides of the second conveying device 31, respectively. When the ceramic brick in front reaches the position of the pushing mechanism 32, the pushing cylinder 322 on the same side drives the pushing wheel assembly 323 to extend, pushing the ceramic brick towards the center of the second conveying device 31. Similarly, the ceramic brick in the rear is also pushed towards the center of the second conveying device 31, so that both ceramic bricks move forward along the center line of the second conveying device 31 to enter the subsequent edge grinding process.

[0101] The second conveying device 31 is preferably a conveyor belt device. A fourth limiting guide wheel group 34 is provided on both sides of the second conveying device 31, and the fourth limiting guide wheel group 34 is located behind the brick pushing mechanism 32.

[0102] Multiple photoelectric proximity switches are also installed in the brick-pushing module 3 to sense the position of the ceramic bricks within the module 3.

[0103] Based on the above-mentioned rapid brick-cutting line, this invention also proposes a method for cutting and dividing bricks, as follows:

[0104] (1) The whole ceramic tile enters the sawing and cutting module 1. First, stress lines are drawn on the top surface of the ceramic tile. Then, the ceramic tile is cut to form two ceramic tiles side by side. The two ceramic tiles move forward in the sawing and cutting module 1 at the same speed.

[0105] Specifically, when the whole ceramic tile enters the sawing and cutting module 1, it first reaches the area of ​​the sawing mechanism 11. The sawing blade 111 of the sawing mechanism 11 cuts stress lines along the top surface of the ceramic tile. Then the ceramic tile enters the area of ​​the cutting mechanism 12. The cutting wheel group 121 of the cutting mechanism 12 applies force to the bottom surface of the ceramic tile from bottom to top, causing the ceramic tile to be divided into two ceramic tile blocks side by side along the stress lines.

[0106] (2) Two ceramic bricks enter the main conveying assembly 21 of the steering module 2. One of the ceramic bricks enters the steering conveying assembly 22 along the transfer device 23 and achieves a 180° turn in the transfer device 23. At the same time, the other ceramic brick continues to move forward along the main conveying assembly 21. The two ceramic bricks move at different speeds. When one of the ceramic bricks completes the turn, it returns to the main conveying assembly 21 along the other transfer device 23 and moves forward with the other ceramic brick in a front-back manner.

[0107] Specifically, two parallel ceramic bricks enter the feeding conveyor mechanism 211 of the main conveying assembly 21 at the same speed. The bottom end of the movable support of the transfer device 23 is lowered by the lifting cylinder 235. The movable wheel 237 of the guide conveyor belt enters the feeding conveyor mechanism 211, and the guide conveyor belt is connected to the conveying area of ​​the feeding conveyor mechanism 211. The ceramic brick that needs to be turned enters the auxiliary conveyor mechanism 221 of the turning conveying assembly 22 along the guide conveyor belt, and then enters the first differential turning mechanism 222, completing the first 90° turn, and then enters the second differential turning mechanism 222 along the auxiliary conveyor mechanism 221. On the differential steering mechanism 222, a second 90° turn is completed, thus completing a 180° turn of the ceramic brick. The cross-sections of the two ceramic bricks are on the same side. The movable wheel 237 of the guide conveyor belt of the second transfer device 23 descends into the discharge conveyor mechanism 213. Finally, the ceramic brick that has completed the turn enters the discharge conveyor mechanism 213 of the main conveyor assembly 21 along the auxiliary conveyor mechanism 221 and the second transfer device 23. During the turning and transportation of one ceramic brick, the other ceramic brick continues to move forward through the main conveyor mechanism 212 and enters the discharge conveyor mechanism 213.

[0108] Since the two ceramic bricks pass through different areas, the ceramic brick that does not need to turn continues forward at its original speed, while the ceramic brick that needs to turn is slower overall due to the differential turning process. Finally, the two ceramic bricks are in a front-and-back state on the discharge conveyor 213, and also in a left-and-right state on the discharge conveyor 213. That is, after the ceramic brick that needs to turn completes the turn, it still moves forward in the original direction.

[0109] It should be noted that during continuous production, the two transfer devices 23 remain connected to the main conveying component 21. When it is not necessary to turn the ceramic brick or when it is necessary to transport a whole ceramic brick that has not been sawn off, the bottom of the two transfer devices 23 is raised, and the turning conveying component 22 is separated from the main conveying component 21.

[0110] (3) The ceramic bricks that do not need to be turned and the ceramic bricks that have been turned enter the brick pushing module 3. The two ceramic bricks are pushed to the central area of ​​the brick pushing module 3 respectively, and then the two ceramic bricks continue to move forward to enter the subsequent processing steps.

[0111] Specifically, when the ceramic tile in the front moves to the area of ​​the pushing mechanism 32, the pushing cylinder 322 on the same side as the ceramic tile drives the pushing wheel assembly 323 to push out and contact the side of the ceramic tile. Under the lateral push and the action of the second conveying device 31, the ceramic tile moves to the center area of ​​the second conveying device and continues to move forward. Similarly, when the ceramic tile in the rear room moves to the area of ​​the pushing mechanism 32, the pushing cylinder 322 on the same side as the ceramic tile (i.e., the pushing cylinder 322 on the other side) drives the pushing wheel assembly 323 to push out, pushing the ceramic tile towards the center area of ​​the second conveying device. Thus, the two ceramic tiles remain in a straight line and enter the subsequent edge grinding process in an orderly manner.

[0112] In this invention, electrical components such as cylinders, photoelectric proximity switches, motors, conveying devices, and conveying assemblies are controlled by a control system, such as a PLC. Figure 9-13 As shown:

[0113] The invention can be divided into a sawing and top-cutting area, a turning and transporting area, and a brick-pushing and centering area, each of which is controlled by a PLC control system.

[0114] like Figure 11 As shown, within the sawing area, the specific position of the ceramic tile is detected by a photoelectric proximity switch. When the ceramic tile is transported to the sensing range of the photoelectric proximity switch, the feedback is sent to the PLC control system. After secondary processing by the system, the cylinder solenoid valve is opened to achieve ceramic tile centering, preparing for the next step of scratching stress lines on the surface of the ceramic tile.

[0115] The position of the scriber is then controlled by a high-precision cylinder. The operation of the scriber on / off by the cylinder's solenoid valve is controlled to determine whether the scriber performs a scribe on the ceramic tile surface. When the solenoid valve is activated, the scriber descends, maintaining its current position to process the surface of the conveyed ceramic tile, marking stress lines. When the solenoid valve is deactivated, the scriber rises, and the ceramic tile surface is not processed; it merely passes over the tile.

[0116] Once stress lines are drawn on the surface of the ceramic tile, the subsequent breaking component remains operational. A photoelectric proximity switch detects the specific position of the ceramic tile during breaking. When the ceramic tile is conveyed to the breaking component area, two high-precision cylinders control the position of the breaking wheel assembly 121. The starting and stopping of the cylinder solenoid valves controls whether the breaking wheel assembly 121 performs breaking processing on the ceramic tile surface. When the cylinder solenoid valves are activated, the breaking wheel assembly 121 lifts the ceramic tile, dividing it along the stress lines into two equal pieces, as shown below. Figure 9-10 Block 1 and Block 2 are shown.

[0117] like Figure 12 As shown, in the turning transport area, blocks 1 and 2 arrive at this area. The speeds of the turning conveyor assembly 22, the main conveyor assembly 21, and the transfer device 23 are controlled by a frequency converter and motor, causing blocks 1 and 2 to be staggered, as shown... Figure 9-10 As shown, blocks 1 and 2 are staggered, maintaining a certain distance. Block 2 travels in a straight line in the turning and transporting area via the main conveyor assembly 21. Block 1 arrives at the turning and transporting assembly 22 via the transfer device 23. The turning and transporting assembly 22 adjusts the speeds of the two belts of the differential steering mechanism 222 via a frequency converter, creating a speed difference between the two belts. When block 1 passes the first differential steering mechanism 222, due to the speed difference between the left and right belts, block 1 will rotate during transport. The rotation angle is controlled by adjusting the frequency converter. Depending on the processing requirements, if block 1 needs to rotate 180° to be evenly distributed between the two steering frames, then it needs to rotate 90° in the first differential steering mechanism 222, and also 90° in the second differential steering mechanism 222. Finally, block 1 returns to the main conveyor assembly 21 via the transfer device 23, and is transported on the same horizontal plane as block 2.

[0118] like Figure 13 As shown, in the brick-pushing centering area, when block 2 reaches the sensing area of ​​the left-side photoelectric proximity switch, feedback is sent to the PLC control system. After secondary processing by the system, the solenoid valve of the left-side brick-pushing cylinder 322 is opened, pushing block 2 from the left side of the third frame 33 to the center position of the third frame 33. When block 1 reaches the sensing area of ​​the right-side photoelectric proximity switch, feedback is sent to the PLC control system. After secondary processing by the system, the solenoid valve of the right-side brick-pushing cylinder is opened, pushing block 1 from the right side of the third frame 33 to the center position of the third frame 33. This ensures that blocks 1 and 2 are located at the center of the third frame 33, aligned and orderly entering the subsequent edge-grinding area.

[0119] This invention integrates ceramic tile cutting and splitting into a single production line. After sawing and top-cutting, the split ceramic tiles enter the turning module 2. During forward transport, the tiles are turned and aligned in the subsequent pushing module 3, completing the splitting process. This invention solves the problem of slow tile turning speed in existing equipment, which cannot keep up with the efficiency of other equipment. The production speed of this rapid cutting and splitting line can even reach 50 pieces / min, matching the efficiency of the preceding and following processes. The production line has a high degree of automation, saving labor costs and significantly improving production efficiency and product qualification rate. Compared with conventional production lines, this invention can increase output per unit time by 1.5 times.
