Description

Technical Field

[0001] The invention relates to the technical field related to the removal of brick blank marks, and in particular to an automatic removal device and method for brick blank marks of a continuous roller press. Background Art

[0002] With the continuous advancement of ceramic production technology, continuous roller presses, as key equipment in modern ceramic production, have been widely used in the large-scale production of ceramic plates. Through the synergistic effect of the upper and lower rollers, this equipment can achieve efficient and continuous pressurization of ceramic raw materials, thereby producing ceramic plates with unlimited length, greatly improving production efficiency and product quality. However, in the actual production process, due to failures of downstream equipment, interruptions in raw material supply or other unforeseen factors, continuous roller presses will inevitably encounter temporary shutdowns.

[0003] During the downtime, due to the interruption of the continuous pressure of the roller press, the partially formed ceramic tiles will leave obvious marks at the stop position. These marks not only destroy the appearance integrity of the ceramic tiles, but also seriously affect its overall quality and reduce the market competitiveness of the products.

[0004] At present, ceramic manufacturers generally adopt manual monitoring and manual processing to deal with this problem. Specifically, when the continuous roller press is shut down and restarted for some reason, a dedicated operator needs to immediately check the ceramic tiles on the production line, manually identify and separate the tiles with imprints. Subsequently, these unqualified tiles will be sent to the crusher for crushing and recycling. Although this method can ensure that unqualified tiles do not flow into subsequent production lines and avoid greater waste of resources, it is highly dependent on manual operation, which not only increases production costs, but also reduces production efficiency. At the same time, the accuracy of manual judgment also fluctuates to a certain extent, and it is difficult to ensure that all imprinted tiles can be accurately identified and processed. Summary of the invention

[0005] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides an automatic cutting device and method for the imprint of brick blanks of a continuous roller press. The uncertainty problem of manual identification and processing of brick blanks can be solved. The equipment automatically controls the cutting, and only a section of the brick blank with the imprint is cut off, and it is not necessary to cut according to the size of the whole brick. Therefore, the material loss and cost are saved to a certain extent, and the automatic operation can be realized at the same time, avoiding the uncertainty caused by manual intervention.

[0006] The technical solution adopted by the present invention to solve the problem is:

[0007] A device for automatically cutting off the imprint of brick blanks produced by a continuous roller press, comprising: a continuous roller press body, the continuous roller press body having a feed end and a discharge end, and being used for continuously pressing brick blanks; a conveying device, the conveying device being installed behind the discharge end; a brick blank cutter, the brick blank cutter being arranged on the conveying device, and being used for cross-cutting brick blanks; a brick blank length measuring sensor, the brick blank length measuring sensor being arranged on the conveying device and being located upstream of the brick blank cutter, and being used for real-time measurement and feedback of the moving length of the brick blank; and a controller, the controller being electrically connected to the continuous roller press body, the conveying device, the brick blank cutter and the brick blank length measuring sensor, and being used for receiving the value fed back by the brick blank length measuring sensor and calculating the position parameters of the brick blank that need to be cut, so as to drive the brick blank cutter to cut bricks.

[0008] By adopting the above solution, the device receives data fed back by the sensor through the controller, and automatically calculates the position parameters of the brick blank to be cut, thereby driving the brick blank cutting machine to perform precise cutting. This avoids the uncertainty of manual identification and processing, and improves accuracy and efficiency; since the device can only cut off the part of the brick blank with the imprint, rather than the entire brick blank, it can save material loss to a certain extent and reduce production costs; automated operation reduces manual intervention, improves production efficiency, and enables the production line to operate more stably and efficiently.

[0009] Furthermore, it also includes a crushing device, which is electrically connected to the controller and installed behind the conveying device to crush the bricks with marks.

[0010] By adopting the above solution, the crushing device is electrically connected to the controller, which means that when the controller recognizes the position of the imprinted brick that needs to be cut, it can not only drive the brick cutting machine to perform precise cutting, but also further instruct the crushing device to crush the imprinted brick. This process is fully automated and does not require human intervention, which greatly improves the processing efficiency and accuracy; the crushing device crushes unqualified bricks into smaller particles or powders, and these crushed materials can be re-entered into the raw material cycle of ceramic production to achieve effective recycling and reuse of resources. This not only helps to reduce production costs, but also conforms to the concept of sustainable development; after adding the crushing device, the entire processing process is more automated, reducing the links of human intervention. This not only reduces labor costs, but also avoids waste of resources and product quality problems caused by improper manual operation or misjudgment.

[0011] Furthermore, a plurality of passive rollers are arranged between the conveying device and the continuous roller press body, for supporting and delivering the bricks rolled out from the continuous roller press body to the conveying device.

[0012] By adopting the above scheme, the passive roller can support the bricks rolled out from the continuous roller press body, preventing them from falling suddenly or being impacted under the action of gravity, thereby avoiding additional damage or marks on the surface of the bricks; by setting up multiple passive rollers, a smooth transition area can be formed, so that the bricks can be smoothly transferred from the continuous roller press body to the conveyor. This helps to maintain the integrity and consistency of the bricks and ensure the smooth progress of subsequent processing steps.

[0013] Furthermore, the brick blank cutting machine includes: a cutting frame, which is assembled above the conveying device; a cutting motor, which is located between the conveying device and the cutting frame; a lifting mechanism, one end of which is connected to the cutting frame, and the other end is connected to the cutting motor, and is used to drive the cutting motor downward to approach the brick blank or upward to move away from the brick blank; a cross-cutting blade, which is drivingly connected to the cutting motor and is used to cross-cut the brick blank when the lifting mechanism drives the cutting motor to move downward.

[0014] By adopting the above solution, when the brick needs to be cut, the lifting mechanism drives the cutting motor and the cross-cutting blade to move downward, so that the blade contacts and cuts the brick. After the cutting is completed, the lifting mechanism drives the cutting motor and the blade to move upward and leave the brick. The whole process can be precisely controlled and adjusted by the control system to achieve automated and efficient production.

[0015] The invention discloses an automatic cutting method for the imprint of a continuous roller press brick blank, which adopts an automatic cutting device for the imprint of a continuous roller press brick blank, and comprises the following steps: a controller continuously records the value fed back by a brick blank length measuring sensor each time a brick blank cutting machine cuts a brick blank, and records the value recorded at the last cutting as S2; when the continuous roller press stops, the controller records the value S0 fed back by the current brick blank length measuring sensor; the controller calculates the position S1 of the brick blank imprint, the length S3 of the brick blank exceeding the cross-cutting blade, the total length S4 of the uncut brick blank, and the number N of brick blanks that can be completely cut according to parameters S0 and S2; after the continuous roller press is restarted, the controller controls the action of the brick blank cutting machine according to the value fed back by the current brick blank length measuring sensor and the calculation result, so as to automatically cut off the brick blank with the imprint.

[0016] By adopting the above scheme, the automatic cutting of the brick blank imprint of the continuous roller press is realized through precise recording, calculation and automatic control. This not only improves the production efficiency, but also ensures the quality of the brick blank. In addition, the method also has certain flexibility and adaptability, and can be adjusted and optimized according to different production conditions and needs.

[0017] Furthermore, the calculation method of the brick blank imprint position S1 is as follows: S1=S0+L1; wherein L1 is the distance between the pressing roller of the continuous roller press and the cross-cutting blade of the brick blank cutting machine.

[0018] By adopting the above scheme, since the mark is usually produced by the pressure roller, the position of the mark can be considered as the position of the point where the pressure roller contacts the brick and produces the mark. Since the distance between the front end of the brick and the pressure roller when the machine is stopped is S0, and the distance between the pressure roller and the cross-cutting blade is L1, the mark position S1 is the sum of S0 and L1, so the calculation is accurate and efficient.

[0019] Furthermore, the length S3 of the brick that exceeds the cross-cutting blade is calculated as follows: S3=S0-S2; and the total length S4 of the uncut brick is calculated as follows: S4=L1+S3=L1+S0-S2.

[0020] By adopting the above scheme and accurately calculating S3 and S4, it can be ensured that the cutting operation is only for the part of the brick with the imprint, avoiding miscutting or missing cutting, thereby improving the accuracy of cutting; after knowing the total length S4 of the uncut brick, the subsequent cutting operation can be reasonably planned to avoid unnecessary waiting and waste, thereby improving the cutting efficiency, and at the same time, the brick material can be used to the maximum extent, reducing waste and improving material utilization.

[0021] Furthermore, the number N of bricks that can be completely cut is calculated as follows: N=S4÷L0; wherein L0 is the standard length of each brick.

[0022] By adopting the above scheme, by calculating N, it is possible to accurately know how many complete bricks can be cut from the remaining uncut bricks. This helps to formulate a more reasonable cutting plan, avoid waste in the cutting process, ensure the maximum utilization of the remaining brick materials, and reduce material waste caused by improper cutting.

[0023] Furthermore, the control steps of the controller for controlling the action of the brick cutting machine are as follows: the controller determines the change of the brick length measurement sensor value S0 in real time; when the controller detects that the current value S0 is less than S2+N×L0, the controller controls the brick cutting machine to perform the brick cutting action normally; when the controller detects that the current value S0 is equal to S2+N×L0, the controller controls the brick cutting machine to start cutting one side of the brick with the mark; when the controller detects that the current value S0 is greater than L1+L3, L3 is the width of the brick mark, and the controller controls the brick cutting machine to cut off the other side of the brick mark.

[0024] By adopting the above scheme, by accurately judging the value change of S0, the controller can accurately control the action timing of the brick cutting machine to ensure that only the brick part with the mark is cut off to avoid miscutting or missing cutting.

[0025] Furthermore, when a crushing device is included in an automatic cutting device for brick imprints of a continuous roller press, the controller also includes a control method for the crushing device: the controller records the value of the brick length measurement sensor when the brick cutting machine cuts off the other side of the brick imprint as S5; it is known that the distance between the cross-cutting blade and the crushing device is L2; ​​when the controller detects that the current value S0=S2+N×L0+L2, the controller controls the crushing device to execute the approach brick instruction and start the brick crushing operation; when the controller detects that the current value S0=S5+L2, the controller controls the crushing device to stop the grinding operation and leave the brick surface.

[0026] By adopting the above solution, the controller can accurately judge and control the action timing of the crushing device, ensuring that the crushing device starts working at the correct position and time, improving the efficiency of brick crushing, avoiding excessive contact and damage of the crushing device to subsequent bricks or equipment, and ensuring the continuity of production and the integrity of the equipment. The entire control process is automatically completed by the controller without manual intervention. This improves the automation level of the production line, reduces labor costs, and reduces errors and safety hazards caused by human operation.

[0027] In summary, the automatic removal device and method for the continuous roller press brick blank imprint provided by the present invention has the following technical effects:

[0028] 1. The automated cutting device can quickly respond and process bricks with marks without manual intervention, which greatly shortens the processing time and improves the overall production efficiency. Through precise calculation and control, the device can only cut off the part with the mark instead of the whole brick, which reduces unnecessary waste and further improves production efficiency.

[0029] 2. The automatic cutting device can accurately identify and cut off the part of the brick with the mark, avoiding the flow of unqualified products into the subsequent production line, thus ensuring the quality and consistency of the final product. Compared with manual identification, the automatic device has higher accuracy and stability, reducing the errors and uncertainties caused by human factors;

[0030] 3. Through automated processing, the need for manual monitoring and processing is reduced, thereby reducing labor costs. Since the parts with imprints can be accurately cut off, the waste of the entire brick is reduced, further reducing material costs;

[0031] 4. The automatic cutting device can work continuously and stably without being affected by human factors, thus enhancing the stability and reliability of the production line;

[0032] 5. The device and method have certain flexibility and adaptability, and can be adjusted and optimized according to different production conditions and requirements. For example, the cutting parameters can be adjusted to adapt to bricks of different sizes or different imprint positions. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0040] Embodiment 1 of the present invention refers to Figure 1-Figure 2 As shown, an automatic cutting device for a continuous roller press brick blank imprint is disclosed, comprising a continuous roller press body 1, a conveying device 2, a brick blank cutter 3, a brick blank length measuring sensor 4 and a controller (not shown in the figure), wherein the continuous roller press body 1 has a feed end 11 and a discharge end 12, and is used for feeding from the feed end 11 to continuously press the brick blank 7 and delivering it from the discharge end 12, the conveying device 2 is installed behind the discharge end 12 to receive the brick blank 7 delivered from the discharge end 12 and continue to deliver it backwards, and optionally, the conveying device 2 includes but is not limited to a conveyor belt or a conveyor roller; the brick blank cutter 3 is arranged on the conveying end 11 to continuously press the brick blank 7 and deliver it from the discharge end 12. The device 2 is used to cross-cut the brick 7; the brick length measuring sensor 4 is arranged on the conveying device 2 and is located upstream of the brick cutting machine 3, and is used to measure and feedback the moving length of the brick 7 in real time. The controller is electrically connected with the continuous roller press body 1, the conveying device 2, the brick cutting machine 3 and the brick length measuring sensor 4, and is used to receive the value fed back by the brick length measuring sensor 4 and calculate the position parameter of the brick 7 to be cut, so as to drive the brick cutting machine 3 to cut bricks; optionally, the controller includes but is not limited to a programmable logic controller, an embedded controller, an industrial computer or an industrial computer. The device receives the data fed back by the sensor through the controller, and automatically calculates the position parameter of the brick 7 to be cut, so as to drive the brick cutting machine 3 to perform precise cutting. This avoids the uncertainty of manual identification and processing, and improves accuracy and efficiency; since the device can only cut off the part of the brick 7 with the imprint, rather than the whole brick 7, it can save material loss to a certain extent and reduce production costs; the automated operation reduces manual intervention, improves production efficiency, and enables the production line to operate more stably and efficiently.

[0041] Specifically, in some embodiments, the continuous roller press body 1 includes an upper driven roller 13, an upper forming roller 14, an upper active roller 15, a lower driven roller 16, a lower forming roller 17, and a lower active roller 18. The upper forming roller 14 and the lower forming roller 17 are arranged opposite to each other, and a rolling surface 19 is formed between the two, which is used to roll the material into a brick 7. A conveying steel belt is wound around the upper driven roller 13, the upper forming roller 14, and the upper active roller 15, and a conveying steel belt is wound around the lower driven roller 16, the lower forming roller 17, and the lower active roller 18. The upper driven roller 13 and the lower driven roller 16 are between the feed end 11, and the upper active roller 15 and the lower active roller 18 are between the discharge end 12. After the material enters from the feed end 11, it passes through the rolling surface 19 between the upper forming roller 14 and the lower forming roller 17 and is pressed into a brick 7, and then sent out from the discharge end 12.

[0042] It should be noted that the upper roller surfaces of the lower driven roller 16 , the lower forming roller 17 , and the lower active roller 18 are on the same horizontal plane to maintain the horizontal transmission of the brick blanks 7 .

[0043] Since there is a gap between the discharge end 12 of the continuous roller press body 1 and the conveying device 2, the brick blank 7 will be pressed down by gravity during the conveying process, so that it cannot be conveyed to the conveying device 2. For this reason, in some embodiments, a plurality of passive rollers 5 are also arranged between the conveying device 2 and the continuous roller press body 1, which are used to support and convey the brick blank 7 rolled out from the continuous roller press body 1 to the conveying device 2. The passive rollers 5 can support the brick blank 7 rolled out from the continuous roller press body 1 to prevent it from suddenly falling or being impacted under the action of gravity, thereby avoiding additional damage or marks on the surface of the brick blank 7; by setting a plurality of passive rollers 5, a smooth transition area can be formed, so that the brick blank 7 can be smoothly transferred from the continuous roller press body 1 to the conveying device 2. This helps to maintain the integrity and consistency of the brick blank 7 and ensure the smooth progress of subsequent processing steps.

[0044] It should be noted that the upper roller surfaces of the plurality of passive roller bodies 5 are all in the same horizontal plane as the upper roller surfaces of the lower driven roller 16 , the lower forming roller 17 , and the lower active roller 18 , so as to provide stable and horizontal conveying conditions.

[0045] In some embodiments, in order to perform more specific and detailed operations on the green brick cutting machine 3, the green brick cutting machine 3 is required to include at least a cutting frame 31, a cutting motor 32, a lifting mechanism 33 and a cross-cutting blade 34. The cutting frame 31 is mounted above the conveying device 2, and the cutting motor 32 is located between the conveying device 2 and the cutting frame 31. One end of the lifting mechanism 33 is connected to the cutting frame 31, and the other end is connected to the cutting motor 32, which is used to drive the cutting motor 32 downward to approach the green brick 7 or upward to move away from the green brick 7. The cross-cutting blade 34 is drivingly connected to the cutting motor 32, which is used to cross-cut the green brick 7 when the lifting mechanism 33 drives the cutting motor 32 to move downward. According to this arrangement, when the green brick 7 needs to be cut, the lifting mechanism 33 drives the cutting motor 32 and the cross-cutting blade 34 to move downward, so that the blade contacts and cuts the green brick 7. After the cutting is completed, the lifting mechanism 33 drives the cutting motor 32 and the blade to move upward and leave the green brick 7. The whole process can be precisely controlled and adjusted by the control system to achieve automated and efficient production. Optionally, the lifting mechanism 33 includes but is not limited to a hydraulic rod, a cylinder or a screw motor, which can control the cross-cutting blade 34 to move up and down to complete the cutting.

[0046] In some embodiments, in order to facilitate the crushing operation after cutting, a crushing device 6 is further provided at the end or rear of the conveyor 2, and the crushing device 6 is electrically connected to the controller. The crushing device 6 is installed at the rear of the conveyor 2 and is used to crush the imprinted brick 7. By electrically connecting the crushing device 6 to the controller, it means that when the controller recognizes the position of the imprinted brick 7 that needs to be cut, it can not only drive the brick cutter 3 to perform precise cutting, but also further instruct the crushing device 6 to crush the imprinted brick 7. This process is fully automated, without manual intervention, and greatly improves the processing efficiency and accuracy; the crushing device 6 crushes the unqualified brick 7 into smaller particles or powders, and these crushed materials can re-enter the raw material cycle of ceramic production to achieve effective recycling and reuse of resources. This not only helps to reduce production costs, but also conforms to the concept of sustainable development; after adding the crushing device 6, the entire processing process is more automated, reducing the links of manual intervention. This not only reduces labor costs, but also avoids waste of resources and product quality problems caused by improper manual operation or misjudgment.

[0047] In this embodiment, the crushing device 6 includes a crusher 61 and a crushing and lifting mechanism 62 for controlling the lifting of the crusher 61. Optionally, the crushing device 6 includes but is not limited to a shearing mechanism or a cutting device, the shearing mechanism includes components such as a slide seat, a mold support frame, a shearing mold, and a hydraulic cylinder, the hydraulic cylinder provides power to drive the shearing mold to cut the brick 7; the cutting device includes components such as a cutter, a cutter mounting plate, and a longitudinal screw transmission mechanism, the longitudinal screw transmission mechanism provides power to drive the cutter to move vertically and horizontally, thereby realizing the cutting operation of the brick 7. In other embodiments, the specific structure of the crushing device 6 is not limited, and it only needs to be able to achieve the crushing effect, and this embodiment does not make any specific limitations.

[0048] The present invention also relates to a method for automatically removing the imprint of a continuous roller press brick blank, which uses the above-mentioned automatic removal device for removing the imprint of a continuous roller press brick blank, and comprises the following steps:

[0049] Parameter record:

[0050] The controller continuously records the value fed back by the brick length measuring sensor 4 each time the brick cutting machine 3 cuts the brick 7. The brick length measuring sensor 4 is referred to as BQ1 below. When the continuous roller press body 1 stops, the controller records the current feedback value of BQ1, which is recorded as S0. The value S0 represents the length of the brick 7 at the sensor position when the machine stops. At the same time, the controller also extracts the value of BQ1 at the start of the last cross-cutting action of the brick cutting machine 3, which is recorded as S2, for subsequent calculation of the length of the brick 7 that has been cross-cut.

[0051] Parameter calculation:

[0052] Since there is a certain distance L1 between the rolling surface 19 and the cross-cutting blade 34, when the machine is stopped, the position on the brick 7 that is L1 away from the cross-cutting blade 34 is the position where the mark is. Therefore, the position S1 of the mark on the brick 7 = S0 + L1. Since the mark is usually produced under the action of the pressure roller, the position of the mark can be considered as the position of the point where the rolling surface 19 contacts the brick 7 and produces the mark.

[0053] The length S3 of the brick 7 that has been cross-cut is equal to the length S0 of the brick 7 at the BQ1 position when the machine is stopped minus the value S2 of the sensor BQ1 when the brick cutting machine 3 started the last cross-cutting action, that is, the length S3 of the brick 7 exceeding the cross-cutting blade 34 = S0-S2.

[0054] The total length S4 of the uncut brick 7 is equal to the distance L1 between the rolling surface 19 and the cross-cutting blade 34 plus the length S3 of the brick 7 that has been cross-cut, that is, the total length S4 of the uncut brick 7 = L1 + S3 = L1 + S0-S2. By accurately calculating S3 and S4, it can be ensured that the cutting operation is only for the part of the brick 7 with the mark, avoiding miscutting or missing cutting, thereby improving the accuracy of cutting; after knowing the total length S4 of the uncut brick 7, the subsequent cutting operation can be reasonably planned to avoid unnecessary waiting and waste, thereby improving the cutting efficiency, and at the same time, the brick 7 material can be used to the maximum extent, reducing waste and improving material utilization.

[0055] The number of blocks N of completely cut bricks 7 is equal to the total length S4 of the uncut bricks 7 divided by the current brick 7 cutting length L0, L0 being the standard length of each brick 7, that is, the number of completely cut bricks 7 N = S4 ÷ L0. Since the bricks 7 are cut in integers, N is the integer part. By calculating N, it is possible to accurately know how many complete bricks 7 can be cut from the remaining uncut bricks 7. This helps to formulate a more reasonable cutting plan, avoid waste in the cutting process, ensure the maximum use of the remaining brick 7 materials, and reduce material waste caused by improper cutting.

[0056] Subsequent automatic cutting: The controller controls the action of the brick cutting machine 3 according to the value fed back by the current brick length measurement sensor 4 and the calculation result, so as to automatically cut off the brick 7 with the mark. Through accurate recording, calculation and automatic control, the automatic cutting of the brick marks of the continuous roller press is realized. This not only improves the production efficiency, but also ensures the quality of the brick 7. In addition, the method also has certain flexibility and adaptability, and can be adjusted and optimized according to different production conditions and requirements.

[0057] Specifically, when the continuous roller press body 1 is started again, the controller will judge the change of the BQ1 value in real time. When the BQ1 value S0 is less than S2+N×L0, it means that the current brick 7 has not reached the position with the mark. At this time, the controller controls the brick cutting machine 3 to perform the brick cutting action normally. At this time, the cut brick 7 is normal and has no mark; when the controller detects that the current value S0 is equal to S2+N×L0, it means that the current brick 7 has reached the position with the mark. At this time, the controller controls the brick cutting machine 3 to start cutting one side of the brick 7 with the mark; when the controller detects that the current value S0 is greater than L1+L3, L3 is the width of the mark of the brick 7, which means that the current brick 7 has completely passed through the cross-cutting blade 34. At this time, the controller controls the brick cutting machine 3 to cut off the other side of the mark of the brick 7. By accurately judging the value change of S0, the controller can accurately control the action timing of the brick cutting machine 3.

[0058] Preferably, in some embodiments, a device for automatically cutting off the imprint of a brick blank of a continuous roller press includes a crushing device 6, and the controller also includes a control method for the crushing device 6: the controller records the value of the brick blank length measuring sensor 4 when the brick blank cutting machine 3 cuts off the other side of the imprint of the brick blank 7 as S5; it is known that the distance between the cross-cutting blade 34 and the crushing device 6 is L2; ​​then when the controller detects that the current value S0 = S2 + N × L0 + L2, it means that the brick blank 7 with the imprint has been cut off and is about to reach the position of the crushing device 6, and the controller controls the crushing device 6 to execute the instruction of approaching the brick blank 7 and start crushing the bricks Operation: When the controller detects that the current value S0=S5+L2, it means that the brick 7 with the cut mark and crushed has left the position of the crushing device 6. At this time, the controller controls the crushing device 6 to stop the grinding operation and leave the surface of the brick 7. The controller can accurately judge and control the action timing of the crushing device 6, ensuring that the crushing device 6 starts working at the correct position and time, improving the efficiency of brick crushing, avoiding excessive contact and damage of the crushing device 6 to the subsequent brick 7 or equipment, and ensuring the continuity of production and the integrity of the equipment. The entire control process is automatically completed by the controller without manual intervention. This improves the automation level of the production line, reduces labor costs, and reduces errors and safety hazards caused by human operations.

[0059] It should be noted that the brick length measurement sensor 4 includes but is not limited to a laser displacement sensor, a photoelectric switch, an inductive sensor or a capacitive sensor, which is not specifically limited in this embodiment. The working principles of these sensors are different, but they all have their own advantages and scope of application. When selecting a sensor, it is necessary to make a comprehensive consideration based on the specific application scenario and requirements. When selecting a sensor, it is necessary to consider factors such as measurement accuracy, measurement range, and working environment to ensure the accuracy and reliability of the measurement results.

[0060] In summary, the automatic removal device and method for the continuous roller press brick blank imprint provided by the present invention has the following technical effects:

[0061] 1. The automated cutting device can quickly respond to and process the bricks 7 with marks without manual intervention, thereby greatly shortening the processing time and improving the overall production efficiency. Through precise calculation and control, the device can only cut off the part with the mark instead of the whole brick 7, which reduces unnecessary waste and further improves production efficiency;

[0062] 2. The automatic cutting device can accurately identify and cut off the 7 parts of the brick with marks, avoiding the flow of unqualified products into the subsequent production line, thus ensuring the quality and consistency of the final product. Compared with manual identification, the automatic device has higher accuracy and stability, reducing the errors and uncertainties caused by human factors;
