Description

An automatic removal device and method for brick blank imprints from a continuous roller press. Technical Field

[0001] This application relates to the technical field of brick blank imprint removal, and in particular to an automatic removal device and method for brick blank imprints from a continuous roller press. Background Technology

[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 slabs. This equipment, through the synergistic action of upper and lower rollers, enables efficient and continuous pressure molding of ceramic raw materials, thereby producing ceramic slabs of unlimited length and greatly improving production efficiency and product quality. However, in actual production, due to downstream equipment failures, raw material supply interruptions, or other unforeseen factors, continuous roller presses inevitably encounter temporary shutdowns.

[0003] During downtime, the interruption of continuous pressure from the roller press leaves noticeable marks on the partially formed ceramic tile blanks at the point of interruption. These marks not only damage the appearance integrity of the ceramic tile blanks but also severely affect their overall quality, reducing the product's market competitiveness.

[0004] Currently, ceramic manufacturers generally address this issue through manual monitoring and handling. Specifically, when a continuous roller press stops and restarts, dedicated operators must immediately inspect the ceramic brick blanks on the production line, manually identifying and separating those with marks. These substandard brick blanks are then sent to a crusher for processing and recycling. While this method ensures that substandard brick blanks do not flow into subsequent production lines, avoiding greater resource waste, it heavily relies on manual operation, increasing production costs and reducing efficiency. Furthermore, the accuracy of manual judgment fluctuates, making it difficult to guarantee that all marked brick blanks can be accurately identified and handled. Summary of the Invention

[0005] To overcome at least one of the defects described in the prior art, this application provides an automatic removal device and method for brick blank imprints from a continuous roller press. This solves the uncertainty problem associated with manual identification and processing of brick blanks. Through automatic control of the cutting process, only a section of the brick blank with imprints is removed, eliminating the need for cutting according to the dimensions of the whole brick. Therefore, it saves material waste and costs to a certain extent, while also achieving automated operation and avoiding uncertainties caused by manual intervention.

[0006] The technical solution adopted in this application to solve its problem is:

[0007] An automatic removal device for brick blank imprints from a continuous roller press includes: a continuous roller press body having a feed end and a discharge end for continuously pressing brick blanks; a conveying device installed behind the discharge end; a brick blank cutter mounted on the conveying device for transversely cutting brick blanks; a brick blank length measuring sensor mounted on the conveying device and located upstream of the brick blank cutter for real-time measurement and feedback of the brick blank's moving length; and a controller electrically connected to the continuous roller press body, the conveying device, the brick blank cutter, and the brick blank length measuring sensor for receiving the values ​​fed back by the brick blank length measuring sensor and calculating the position parameters of the brick blank to be cut, thereby driving the brick blank cutter to cut the brick.

[0008] By adopting the above scheme, the device receives data from the sensors via a controller and automatically calculates the positional 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, improving accuracy and efficiency. Since the device can only cut off the brick blank with marks, rather than the entire brick blank, it can save material waste to a certain extent and reduce production costs. Automated operation reduces human intervention, improves production efficiency, and enables the production line to operate more stably and efficiently.

[0009] In some embodiments, a crushing device is also included, which is electrically connected to the controller and is installed behind the conveying device for crushing the brick blanks with imprints.

[0010] By adopting the above solution, the crushing device is electrically connected to the controller. This means that when the controller identifies the location of the brick blank with the indentation that needs to be removed, it can not only drive the brick blank cutting machine to make precise cuts, but also instruct the crushing device to crush the brick blank with the indentation. This process is fully automated, requiring no manual intervention, which greatly improves processing efficiency and accuracy. The crushing device breaks down unqualified brick blanks into smaller particles or powder, and these crushed materials can be reintroduced into the raw material cycle of ceramic production, achieving effective resource recovery and reuse. This not only helps reduce production costs but also aligns with the concept of sustainable development. With the addition of the crushing device, the entire processing flow is more automated, reducing the need for manual intervention. This not only reduces labor costs but also avoids resource waste and product quality problems caused by improper operation or misjudgment.

[0011] In some embodiments, a plurality of passive rollers are provided between the conveying device and the continuous roller press body to support the brick blanks rolled out from the continuous roller press body and convey them to the conveying device.

[0012] By adopting the above scheme, the passive rollers can support the brick blanks rolled out from the continuous roller press body, preventing them from suddenly falling or being impacted under gravity, thus avoiding additional damage or marks on the surface of the brick blanks. By setting multiple passive rollers, a smooth transition zone can be formed, allowing the brick blanks to be smoothly transferred from the continuous roller press body to the conveying device. This helps maintain the integrity and consistency of the brick blanks, ensuring the smooth progress of subsequent processing steps.

[0013] In some embodiments, the brick blank cutting machine includes: a cutting frame mounted above the conveying device; a cutting motor located between the conveying device and the cutting frame; a lifting mechanism connected at one end to the cutting frame and at the other end to the cutting motor, for driving the cutting motor downward toward the brick blank or upward away from the brick blank; and a cross-cutting blade driven by the cutting motor, for cross-cutting the brick blank when the lifting mechanism drives the cutting motor to move downward.

[0014] By adopting the above scheme, when the brick blank needs to be cut, the lifting mechanism drives the cutting motor and the cross-cutting blade downwards, so that the blade contacts and cuts the brick blank. After cutting, the lifting mechanism then drives the cutting motor and the blade upwards, removing them from the brick blank. The entire process can be precisely controlled and adjusted by the control system to achieve automated and efficient production.

[0015] An automatic removal method for brick blank imprints from a continuous roller press, employing an automatic removal device for brick blank imprints from a continuous roller press, includes the following steps: A controller continuously records the value fed back by the brick blank length measuring sensor each time the brick blank cutter cuts the brick blank, and records the value recorded during the last cut as S2; when the continuous roller press stops, the controller records the current value fed back by the brick blank length measuring sensor as S0; the controller calculates the brick blank imprint position S1, the length of the brick blank exceeding the cross-cutting blade S3, the total length of the uncut brick blank S4, and the number of brick blanks that can be completely cut N based on parameters S0 and S2; after the continuous roller press restarts, the controller controls the brick blank cutter to automatically remove the brick blanks with imprints based on the current value fed back by the brick blank length measuring sensor and the calculation results.

[0016] By adopting the above scheme, and through precise recording, calculation, and automatic control, the automatic removal of brick blank imprints from continuous roller presses is achieved. This not only improves production efficiency but also ensures the quality of the brick blanks. Furthermore, this method offers flexibility and adaptability, allowing for adjustments and optimization based on different production conditions and needs.

[0017] In some embodiments, the brick blank imprint position S1 is calculated as follows: S1=S0+L1; where L1 is the distance between the pressure roller of the continuous roller press and the cross-cutting blade of the brick blank cutter.

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

[0019] In some embodiments, the length S3 of the brick blank exceeding the cross-cutting blade is calculated as follows: S3 = S0 - S2; then the total length S4 of the uncut brick blank 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 aimed at the brick blank with the imprint, avoiding miscutting or missing cutting, thereby improving the accuracy of cutting. After knowing the total length S4 of the uncut brick blank, subsequent cutting operations can be planned in a reasonable manner, avoiding unnecessary waiting and waste, thereby improving cutting efficiency. At the same time, the brick blank material can be utilized to the maximum extent, reducing waste and improving material utilization.

[0021] In some implementations, the number N of brick blanks that can be completely cut is calculated as follows: N = S4 ÷ L0; where L0 is the standard length of each brick blank.

[0022] By employing the above method and calculating N, we can accurately determine how many complete brick blanks can be cut from the remaining uncut brick blanks. This helps in developing a more rational cutting plan, avoiding waste during the cutting process, ensuring maximum utilization of remaining brick blank material, and reducing material waste caused by improper cutting.

[0023] In some embodiments, the control steps for the controller to control the brick cutting machine are as follows: the controller judges the change of the brick length measuring sensor value S0 in real time; when the controller detects that the current value S0 < 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 = S2 + N × L0, the controller controls the brick cutting machine to start cutting off one side of the brick with the imprint; when the controller detects that the current value S0 > L1 + L3, where L3 is the width of the brick imprint, the controller controls the brick cutting machine to cut off the other side of the brick imprint.

[0024] By adopting the above scheme and accurately judging the change in the value of S0, the controller can accurately control the timing of the brick cutting machine's action, ensuring that only the brick blank with the mark is cut off, avoiding miscutting or missing cuts.

[0025] In some embodiments, when an automatic removal device for brick blank imprints in a continuous roller press includes a crushing device, the controller further includes a control method for the crushing device: the controller records the brick blank length measurement sensor value as S5 when the brick blank cutter removes the other side of the brick blank imprint; the distance between the cross-cutting blade and the crushing device is known to be L2; then when the controller detects the current value S0 = S2 + N × L0 + L2, the controller controls the crushing device to execute a command to approach the brick blank and start the brick crushing operation; when the controller detects the current value S0 = S5 + L2, the controller controls the crushing device to execute a stop grinding operation and detach from the brick blank surface.

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

[0027] In summary, the automatic removal device and method for brick blank imprints from a continuous roller press provided in this application have the following technical advantages:

[0028] 1. The automated cutting device can quickly respond to and process brick blanks 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 cut off only the marked part instead of the whole brick blank, which reduces unnecessary waste and improves production efficiency.

[0029] 2. The automatic cutting device can accurately identify and cut off the brick blanks with marks, preventing unqualified products from flowing into the subsequent production line, thereby ensuring the quality and consistency of the final product. Compared with manual identification, the automated device has higher accuracy and stability, and reduces errors and uncertainties caused by human factors.

[0030] 3. Automated processing reduces the need for manual monitoring and handling, thereby reducing labor costs. Because it can accurately cut off the parts with marks, it reduces the waste of whole brick blanks and lowers material costs.

[0031] 4. The automated cutting device can work continuously and stably, unaffected by human factors, thereby enhancing the stability and reliability of the production line;

[0032] 5. The device and method have a certain degree of flexibility and adaptability, and can be adjusted and optimized according to different production conditions and needs. For example, the cutting parameters can be adjusted to adapt to different sizes of brick blanks or different imprint positions. Attached Figure Description

[0036] To facilitate understanding of the embodiments of this application, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments, and the various embodiments do not constitute a limitation on the embodiments of this application.

[0037] In the description of this application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Embodiment 1 of this application, as shown in Figures 1-2, discloses an automatic removal device for brick blank imprints from a continuous roller press. The device includes 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). The continuous roller press body 1 has an inlet end 11 and an outlet end 12, used for continuously pressing brick blanks 7 from the inlet end 11 and sending them out from the outlet end 12. The conveying device 2 is installed behind the outlet end 12 to receive the brick blanks 7 sent out from the outlet end 12 and continue conveying them backward. Optionally, the conveying device 2 may include, but is not limited to, a conveyor belt or conveyor rollers. The brick blank cutter 3... The device is mounted on the conveying device 2 for transverse cutting of the brick blank 7. The brick blank length measuring sensor 4 is mounted on the conveying device 2 and located upstream of the brick blank cutting machine 3. It is used to measure and provide feedback on the moving length of the brick blank 7 in real time. The controller is electrically connected to the continuous roller press body 1, the conveying device 2, the brick blank cutting machine 3, and the brick blank length measuring sensor 4. It is used to receive the values ​​fed back by the brick blank length measuring sensor 4 and calculate the position parameters of the brick blank 7 that need to be cut, so as to drive the brick blank cutting machine 3 to cut the brick. Optionally, the controller may include, but is not limited to, a programmable logic controller, an embedded controller, an industrial computer, or an industrial control computer. This device receives the data fed back by the sensor through the controller and automatically calculates the position parameters of the brick blank 7 that need to be cut, thereby driving the brick blank cutting machine 3 to perform precise cutting. This avoids the uncertainty of manual identification and processing, and improves accuracy and efficiency. Since this device can cut only the part of the brick blank 7 with marks, rather than the whole brick blank 7, it can save material waste 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.

[0039] Specifically, in some embodiments, the continuous roller press body 1 includes an upper driven roller 13, an upper forming roller 14, an upper driving roller 15, a lower driven roller 16, a lower forming roller 17, and a lower driving roller 18. The upper forming roller 14 and the lower forming roller 17 are arranged opposite to each other, with a roller pressing surface 19 between them, used to roll the material into brick blanks 7. A conveyor steel belt is wound around the upper driven roller 13, the upper forming roller 14, and the upper driving roller 15, and a conveyor steel belt is wound around the lower driven roller 16, the lower forming roller 17, and the lower driving roller 18. The area between the upper driven roller 13 and the lower driven roller 16 is the feed end 11, and the area between the upper driving roller 15 and the lower driving roller 18 is the discharge end 12. After the material enters from the feed end 11, it is pressed into brick blanks 7 through the roller pressing surface 19 between the upper forming roller 14 and the lower forming roller 17 and then sent out from the discharge end 12.

[0040] It should be noted that the upper roller surfaces of the lower driven roller 16, the lower forming roller 17, and the lower driving roller 18 are on the same horizontal plane to maintain the horizontal conveying of the brick blank 7.

[0041] Because 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 may be pressed down by gravity during the conveying process, resulting in it being unable to be conveyed to the conveying device 2. Therefore, in some embodiments, multiple passive rollers 5 are provided between the conveying device 2 and the continuous roller press body 1 to support the brick blank 7 rolled out of the continuous roller press body 1 and convey it to the conveying device 2. The passive rollers 5 can support the brick blank 7 rolled out of the continuous roller press body 1, preventing it from suddenly falling or being impacted under gravity, thereby avoiding additional damage or marks on the surface of the brick blank 7. By providing multiple passive rollers 5, a smooth transition area can be formed, allowing the brick blank 7 to be smoothly transferred from the continuous roller press body 1 to the conveying device 2. This helps maintain the integrity and consistency of the brick blank 7, ensuring the smooth progress of subsequent processing steps.

[0042] It should be noted that the upper roller surfaces of the multiple passive rollers 5 are all on the same horizontal plane as the upper roller surfaces of the lower driven roller 16, the lower forming roller 17, and the lower driving roller 18, so as to provide stable and horizontal conveying conditions.

[0043] In some embodiments, for more detailed operation of the brick blank cutting machine 3, the brick blank cutting machine 3 needs 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. 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. It is used to drive the cutting motor 32 downward toward or upward away from the brick blank 7. The cross-cutting blade 34 is driven by the cutting motor 32 and is used to cross-cut the brick blank 7 when the lifting mechanism 33 drives the cutting motor 32 downward. Thus, when the brick blank 7 needs to be cut, the lifting mechanism 33 drives the cutting motor 32 and the cross-cutting blade 34 downward, so that the blade contacts and cuts the brick blank 7. After cutting, the lifting mechanism 33 then drives the cutting motor 32 and the blade upward, away from the brick blank 7. The entire process can be precisely controlled and adjusted through a control system to achieve automated and efficient production. Optionally, the lifting mechanism 33 may include, but is not limited to, a hydraulic rod, a cylinder, or a lead screw motor, capable of controlling the up-and-down movement of the cross-cutting blade 34 to complete the cutting.

[0044] In some embodiments, to facilitate the crushing operation after cutting, a crushing device 6 is also provided at the end or rear of the conveying device 2. The crushing device 6 is electrically connected to the controller. Installed behind the conveying device 2, the crushing device 6 is used to crush the brick blanks 7 with indentations. By electrically connecting the crushing device 6 to the controller, it means that when the controller identifies the location of the brick blank 7 with indentations to be cut, it can not only drive the brick blank cutting machine 3 to perform precise cutting, but also instruct the crushing device 6 to crush the brick blanks 7 with indentations. This process is fully automated, requiring no manual intervention, greatly improving processing efficiency and accuracy. The crushing device 6 crushes the unqualified brick blanks 7 into smaller particles or powder. These crushed materials can be reintroduced into the raw material cycle of ceramic production, achieving effective resource recovery and reuse. This not only helps reduce production costs but also aligns with the concept of sustainable development. Adding the crushing device 6 further automates the entire process, reducing the need for manual intervention. This not only reduces labor costs but also avoids resource waste and product quality problems caused by improper operation or misjudgment.

[0045] In some embodiments, the crushing device 6 includes a crusher 61 and a crushing lifting mechanism 62 for controlling the lifting and lowering 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, 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 blank 7. The cutting device includes components such as a cutter, a cutter mounting plate, and a longitudinal screw drive mechanism. The longitudinal screw drive mechanism provides power to drive the cutter to move vertically and horizontally, thereby realizing the cutting operation of the brick blank 7. In other embodiments, the specific structure of the crushing device 6 is not limited, as long as the crushing effect can be achieved. This embodiment does not impose specific limitations.

[0046] This application also relates to an automatic removal method for brick blank imprints from a continuous roller press, employing the aforementioned automatic removal device for brick blank imprints from a continuous roller press, comprising the following steps:

[0047] Parameter recording:

[0048] The controller continuously records the value fed back by the brick blank length measuring sensor 4 each time the brick blank cutter 3 cuts the brick blank 7. Hereinafter, the brick blank length measuring sensor 4 will be referred to as BQ1. When the continuous roller press body 1 stops, the controller records the current value fed back by BQ1, denoted as S0. The value S0 represents the length of the brick blank 7 at the sensor position when the machine stops. Simultaneously, the controller also extracts the value of BQ1 at the start of the previous transverse cutting action of the brick blank cutter 3, denoted as S2, for subsequent calculation of the length of the brick blank 7 that has already been transversely cut.

[0049] Parameter calculation:

[0050] Because there is a certain distance L1 between the roller pressing surface 19 and the cross-cutting blade 34, when the machine stops, the position on the brick blank 7 at a distance L1 from the cross-cutting blade 34 is the location of the imprint. Therefore, the imprinted position S1 on the brick blank 7 is S0 + L1. Since the imprint is usually produced under the action of the pressure roller, the position of the imprint can be considered as the point where the roller pressing surface 19 contacts the brick blank 7 and produces the imprint.

[0051] The length S3 of the brick blank 7 that has been transversely cut is equal to the length S0 of the brick blank 7 at position BQ1 when the machine stops, minus the value S2 of sensor BQ1 at the start of the last transverse cutting action of the brick blank cutting machine 3. That is, the length S3 of the brick blank 7 that exceeds the transverse cutting blade 34 is S0-S2.

[0052] The total length S4 of the uncut brick blank 7 is equal to the distance L1 between the roller surface 19 and the cross-cutting blade 34 plus the length S3 of the brick blank 7 that has already been cross-cut, i.e., the total length S4 of the uncut brick blank 7 = L1 + S3 = L1 + S0 - S2. By accurately calculating S3 and S4, it can be ensured that the cutting operation is only aimed at the part of the brick blank 7 with the marks, avoiding miscutting or missing cutting, thereby improving the accuracy of cutting. Knowing the total length S4 of the uncut brick blank 7, subsequent cutting operations can be planned in a reasonable way, avoiding unnecessary waiting and waste, thereby improving cutting efficiency. At the same time, the material of the brick blank 7 can be utilized to the maximum extent, reducing waste and improving material utilization rate.

[0053] The number N that can be completely cut into brick blanks 7 is equal to the total length S4 of the uncut brick blanks 7 divided by the current cutting length L0 of the brick blank 7, where L0 is the standard length of each brick blank 7. Therefore, the number of completely cut brick blanks 7 is N = S4 ÷ L0. Since the number of brick blanks 7 is an integer, N is rounded to the nearest integer. By calculating N, we can accurately determine how many complete brick blanks 7 can be cut from the remaining uncut brick blanks 7. This helps to develop a more reasonable cutting plan, avoid waste during the cutting process, ensure maximum utilization of the remaining brick blanks 7 material, and reduce material waste caused by improper cutting.

[0054] Subsequent automatic removal: The controller controls the brick cutting machine 3 to automatically remove the brick blanks 7 with imprints based on the values ​​fed back from the current brick blank length measuring sensor 4 and the calculation results. Through precise recording, calculation, and automatic control, automatic removal of brick blank imprints from the continuous roller press is achieved. This not only improves production efficiency but also ensures the quality of the brick blanks 7. In addition, this method has a certain degree of flexibility and adaptability, and can be adjusted and optimized according to different production conditions and needs.

[0055] Specifically, when the continuous roller press body 1 restarts, the controller will judge the change of the BQ1 value in real time. When the BQ1 value S0 < S2 + N × L0, it means that the current brick blank 7 has not yet reached the position with an imprint. At this time, the controller controls the brick blank cutter 3 to perform the brick cutting action normally. The brick blank 7 cut at this time is normal and without an imprint. When the controller detects that the current value S0 = S2 + N × L0, it means that the current brick blank 7 has reached the position with an imprint. At this time, the controller controls the brick blank cutter 3 to start cutting off one side of the brick blank 7 with an imprint. When the controller detects that the current value S0 > L1 + L3, where L3 is the width of the imprint of the brick blank 7, it means that the current brick blank 7 has completely passed through the cross-cutting blade 34. At this time, the controller controls the brick blank cutter 3 to cut off the other side of the imprint of the brick blank 7. By accurately judging the change of the value of S0, the controller can accurately control the timing of the action of the brick blank cutter 3.

[0056] In some embodiments, an automatic removal device for brick blank imprints in a continuous roller press includes a crushing device 6. The controller also includes a control method for the crushing device 6: the controller records the brick blank length measurement sensor 4 value as S5 when the brick blank cutter 3 cuts off the other side of the brick blank imprint 7; the distance between the cross-cutting blade 34 and the crushing device 6 is known to be L2; then when the controller detects the current value S0 = S2 + N × L0 + L2, it indicates that the brick blank 7 with the imprint has been cut off and is about to reach the position of the crushing device 6. At this time, the controller controls the crushing device 6 to execute a command to approach the brick blank 7 and begin the brick crushing operation; when the controller detects the current value S0 = At step S5+L2, it indicates that the brick blank 7, after having its imprint removed and undergoing crushing, has left the position of the crushing device 6. At this point, the controller instructs the crushing device 6 to stop grinding and detach from the surface of the brick blank 7. The controller can precisely determine and control the timing of the crushing device 6's action, ensuring that it starts working at the correct position and time, improving brick crushing efficiency, avoiding excessive contact and damage to subsequent brick blanks 7 or equipment, and guaranteeing production continuity and equipment integrity. The entire control process is completed automatically by the controller without manual intervention. This increases the automation level of the production line, reduces labor costs, and minimizes errors and safety hazards caused by human operation.

[0057] It should be noted that the brick blank length measuring sensor 4 includes, but is not limited to, a laser displacement sensor, a photoelectric switch, an inductive sensor, or a capacitive sensor. This embodiment does not impose a specific limitation. These sensors have different working principles, but each has its own advantages and applicable range. When selecting a sensor, it is necessary to comprehensively consider the specific application scenario and requirements. Factors such as measurement accuracy, measurement range, and working environment need to be considered to ensure the accuracy and reliability of the measurement results.

[0058] In summary, the automatic removal device and method for brick blank imprints from a continuous roller press provided in this application have the following technical advantages:

[0059] 1. The automated cutting device can quickly respond to and process brick blanks 7 with imprints without manual intervention, thereby greatly shortening the processing time and improving the overall production efficiency. Through precise calculation and control, the device can cut off only the imprinted part instead of the whole brick blank 7, which reduces unnecessary waste and improves production efficiency.

[0060] 2. The automatic cutting device can accurately identify and cut off 7 parts of brick blanks with imprints, preventing unqualified products from flowing into subsequent production lines, thereby ensuring the quality and consistency of the final product.
