Description

Technical Field

[0001] This invention relates to the field of hot stamping and die-cutting technology, and in particular to an electronic registration and correction device and method based on hot stamping and die-cutting technology. Background Technology

[0002] Hot stamping and die-cutting is a combined process widely used in industries such as printing and packaging. It combines hot stamping and die-cutting techniques to achieve the desired effect in terms of appearance and shape.

[0003] Hot stamping primarily utilizes the principle of heat transfer. Metal foil (such as gold or silver foil) or pigment foil is passed through a heated hot stamping stencil under pressure, transferring the metallic sheen or pigment layer from the foil to the surface of the material to be stamped (such as paper, leather, or plastic). Hot stamping stencils are typically made of metals like copper or zinc, and their surfaces are engraved to create the desired pattern or text. When the hot stamping stencil is heated to a certain temperature (generally between 100-180℃, the exact temperature varies depending on the foil and material) and pressure is applied, the portion of the foil in contact with the stencil adheres tightly to the material, achieving the hot stamping effect.

[0004] Die-cutting is a process that uses a die-cutting blade and a pressure device to cut printed materials or other materials into a pre-designed shape. The die-cutting blade is typically made of steel, and its blade shape depends on the desired shape. During die-cutting, the material is placed between a die-cutting plate (usually a wooden or metal plate with a die-cutting blade and creasing blade mounted on it) and a pressure plate. When pressure is applied, the die-cutting blade cuts into the material, removing the unwanted portion and leaving the desired shape. Simultaneously, the creasing blade creates creases in the material, facilitating subsequent folding operations.

[0005] Currently, in the paper product processing, positional misalignment can lead to problems such as inaccurate cutting dimensions and misaligned printed patterns, resulting in a large number of defective products. If the paper is misaligned during the printing process, the originally exquisite patterns and text may be printed on the edge of the product or even beyond the product area, making the product unsellable. In traditional paper processing, in order to avoid positional misalignment, frequent manual inspection and adjustment are often required, which seriously affects the processing speed. Therefore, this device provides an electronic registration and correction device and method based on hot stamping and die-cutting process. Summary of the Invention

[0006] This invention provides an electronic registration and correction device and method based on hot stamping and die-cutting processes to solve the aforementioned technical problems.

[0007] The embodiments of the present invention adopt the following technical solution: including a belt conveyor and hot stamping die-cutting equipment, characterized in that it further includes an auxiliary pressing mechanism for pressing and assisting the movement of the product, a rotating mechanism for rotating the auxiliary pressing mechanism, a surrounding position conversion mechanism for rotating the rotating mechanism around the product, a lifting mechanism for adjusting and supporting the surrounding position conversion mechanism, and a sensor mechanism for multi-functional sensing of the paper product. The sensor mechanism includes a photoelectric sensor, a color mark sensor, an inductive sensor, an ultrasonic sensor, and a capacitive sensor. The hot stamping die-cutting equipment is located beside the auxiliary pressing mechanism, and the sensor mechanism is located below the front end of the hot stamping die-cutting equipment and is all facing downwards.

[0008] Furthermore, the lifting mechanism includes a lifting base, a lifting rod, a lifting hydraulic cylinder, and a lifting bracket. There are two lifting bases, which are symmetrically arranged on both sides of the belt conveyor and located on the ground. The lifting rod is mounted on one of the lifting bases, and the lifting hydraulic cylinder is mounted on the other lifting base. The lifting rod and the lifting hydraulic cylinder are symmetrically arranged. There are two lifting brackets, which are symmetrically arranged on corresponding lifting bases. The telescopic end of the lifting hydraulic cylinder passes through the corresponding lifting bracket, and the telescopic end of the lifting rod passes through the corresponding lifting bracket.

[0009] Furthermore, the surrounding position conversion mechanism includes a surrounding plate, a surrounding ring, a fixed shell, a surrounding gear, and a drive motor. The fixed shell is disposed on the output end of the lifting hydraulic cylinder. The two ends of the surrounding plate are respectively disposed on the upper ends of the fixed shell and the lifting rod. The drive motor is disposed on the surrounding plate, and the output end of the drive motor is disposed downward and passes through the surrounding plate and is located inside the fixed shell. The surrounding gear is disposed on the output end of the drive motor inside the fixed shell. The surrounding ring is rotatably connected to the lower end of the surrounding plate, and a plurality of teeth that are adapted to mesh with the surrounding gear are arranged around the surrounding ring.

[0010] Furthermore, the rotating mechanism includes a rotary motor, a rotating frame, a rotating shaft, a first transmission assembly, and a second transmission assembly. The rotary motor is located inside the surrounding ring, the rotating frame is located inside the surrounding ring, the output end of the rotary motor passes through the rotating frame and is rotatably connected, and the rotating shaft is located on the output end of the rotary motor. The first transmission assembly and the second transmission assembly have the same structure.

[0011] Furthermore, the auxiliary pressing mechanism includes a first shaft, a second shaft, a third shaft, and pressing rollers. The first shaft, the second shaft, and the third shaft are arranged at equal intervals and are all rotatably connected to the inner wall of the surrounding ring. There are a plurality of pressing rollers, which are arranged in three groups. The three groups of pressing rollers are respectively sleeved on the first shaft, the second shaft, and the third shaft. The second shaft is connected to the rotating shaft.

[0012] Furthermore, the first transmission assembly includes a driving wheel, a driven wheel, and a belt. The driving wheel is mounted on a rotating shaft and on a second shaft. The driven wheel is mounted on a third shaft, and the belt is mounted on the driving wheel and the transmission wheel.

[0013] Furthermore, the driving wheel in the second transmission assembly is mounted on the second shaft, and the driven wheel in the second transmission assembly is mounted on the first shaft.

[0014] Furthermore, the rotary motor is a DC motor.

[0015] An electronic registration and correction device and method based on hot stamping and die-cutting process, comprising the following steps:

[0016] S1: When the product is hot stamping and die-cutting, the belt conveyor drives the product to be transported. When the product is transported to the underside of the auxiliary pressing mechanism, the distance adjustment of the lifting mechanism allows the auxiliary pressing mechanism to press onto the product, which plays a supporting role in preventing the product from shifting during the operation.

[0017] S2: Before the product is transported into the hot stamping and die-cutting equipment for processing, in order to ensure the product processing position is accurate and prevent deviation, the product position is accurately monitored by a sensor mechanism. The photoelectric sensor detects whether the product has moved to the required detection position and checks whether the product position is correct.

[0018] S3: After the product is detected by the photoelectric sensor, the thickness and number of sheets of the product are detected by the ultrasonic sensor. Utilizing the characteristics of ultrasonic waves propagating in different media, the propagation time and intensity of ultrasonic waves will change when the product passes through the sensor. The sensor judges the thickness and number of sheets of the product based on these changes. If the number of sheets is greater than one, it is judged to be incorrect and an alarm is triggered.

[0019] S4: The capacitive sensor detects the material and humidity of the product. The sensor can detect changes in the material and humidity based on the product's dielectric constant. If the detected product fails to meet the requirements, an error is identified, and an alarm is triggered.

[0020] S5: The inductive sensor detects metal markings or magnetic materials on the product. The inductive sensor can detect these markings or materials by sensing changes in the magnetic field. The position of the inductive sensor matches the position of the corresponding metal marking on the product. In other words, if the two positions match, it is normal and the operation can continue. If there is an error, the auxiliary pressing mechanism, rotating mechanism, surrounding position conversion mechanism and lifting mechanism will work together to adjust the position of the product.

[0021] S6: Through a color mark sensor, it accurately identifies color markings on products. It is specifically designed to detect specific color markings on products and has high color recognition accuracy and stability. The color mark sensor can accurately detect the position and color information of the color mark on the product according to preset color parameters, providing accurate positioning signals for subsequent printing, cutting, packaging and other processes. After the color information of the color mark position set on the product corresponds to the position detected by the color mark sensor, that is, the two positions match, it is normal and the operation can continue. If an error is detected, the product position is adjusted by the coordinated operation of the auxiliary pressing mechanism, the rotating mechanism, the surrounding position conversion mechanism and the lifting mechanism.

[0022] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0023] Firstly, large-format products printed with errors due to product positioning cannot be repaired and must be discarded. Position conversion design can prevent these errors, allowing for full utilization of raw materials and reducing waste. For example, in commercial printing, paper costs typically account for a significant proportion of total costs. Precise position control ensures that every sheet of paper is used effectively, reducing raw material consumption and thus lowering production costs. For special-purpose papers, such as art paper and specialty paper, which are more expensive, minimizing waste due to positional errors is even more crucial. Position conversion mechanisms can precisely adjust the position during the processing of these high-value paper products, ensuring processing quality and preventing the discarding of expensive raw materials due to errors, thus saving costs for the company.

[0024] Secondly, when the paper product is misaligned, it may cause additional wear and tear on the processing equipment. For example, in paper cutting machines, misaligned paper may cause uneven force on the blades, leading to faster blade wear and requiring more frequent blade replacements. Precise position conversion ensures that the paper passes correctly through the cutting area, reducing abnormal blade wear, extending equipment lifespan, and lowering maintenance costs. In printing equipment, misalignment may cause collisions or abnormal contact between the print head and the paper product, damaging the print head. The position conversion system ensures the accurate position of the paper during the printing process, reducing the possibility of such damage, lowering equipment repair and replacement costs, and further reducing production costs. This automated position adjustment function can also be controlled through an intuitive operating interface. Operators can easily view the paper position information on the control panel and make simple parameter settings as needed, such as adjusting the accuracy and speed of position adjustment, further simplifying the operation process and improving ease of operation.

[0025] Thirdly, the position conversion system can be integrated with sensor mechanisms and control systems to achieve intelligent paper processing. For example, in conjunction with paper thickness sensors and tension sensors, the system can dynamically adjust the position conversion strategy based on the actual characteristics of the paper. If the paper thickness changes, the system can automatically adjust the force and angle to ensure positional accuracy. Simultaneously, the position conversion system can collect and analyze paper position data, providing valuable information for production management. Through the analysis of large amounts of data, patterns of paper position deviation can be discovered, such as deviations that are prone to occur under specific processing speeds, paper types, or environmental conditions. This allows for further optimization of the processing process, achieving intelligent production management and improving the enterprise's production management level and competitiveness.

[0026] Fourth, during product processing, positional deviations can lead to inaccurate cutting dimensions and misaligned printed patterns, resulting in a large number of defective products. By designing a positional conversion mechanism, paper positional deviations can be corrected in real time, ensuring that each processing step accurately targets the correct position of the paper. For example, in greeting card printing, if the paper is misaligned, the originally exquisite patterns and text may be printed on the edge of the card or even beyond its designated area, rendering the card unsellable. Precise positional adjustment ensures that the patterns and text are perfectly positioned on the card, greatly reducing the number of defective products caused by positional deviations and improving the product pass rate.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] This invention provides an electronic registration and correction device based on hot stamping and die-cutting technology, including a belt conveyor 1 and a hot stamping and die-cutting processing equipment 2. It also includes an auxiliary pressing mechanism 6 for pressing and assisting the movement of the product, a rotating mechanism 5 for rotating the auxiliary pressing mechanism 6, a surrounding position conversion mechanism 4 for rotating the rotating mechanism 5 around it, a lifting mechanism 3 for adjusting and supporting the surrounding position conversion mechanism 4, and a sensor mechanism 7 for multi-functional sensing of the paper product. The sensor mechanism 7 includes a photoelectric sensor 71, a color mark sensor 72, an inductive sensor 73, an ultrasonic sensor 74, and a capacitive sensor 75. The hot stamping and die-cutting processing equipment 2 is located beside the auxiliary pressing mechanism 6, and the sensor mechanism 7 is located below the front end of the hot stamping and die-cutting processing equipment 2, all facing downwards.

[0042] Large-format products printed with errors due to product positioning cannot be repaired and must be discarded. Position conversion design can prevent these errors, allowing for fuller utilization of raw materials and reducing waste. For example, in commercial printing, paper costs typically account for a significant proportion of total costs. Precise position control ensures that every sheet of paper is used effectively, reducing raw material consumption and thus lowering production costs. For special-purpose papers, such as art paper and specialty paper, which are more expensive, minimizing waste due to positional errors is even more crucial. Position conversion mechanisms can precisely adjust the position during the processing of these high-value paper products, ensuring processing quality and preventing the discarding of expensive raw materials due to errors, thus saving costs for the company.

[0043] When paper products are misaligned, it can cause additional wear and tear on processing equipment. For example, in paper cutting machines, misaligned paper can cause uneven force on the cutting tools, leading to faster tool wear and requiring more frequent tool replacements. Precise position conversion ensures that the paper passes correctly through the cutting area, reducing abnormal tool wear, extending equipment lifespan, and lowering maintenance costs. In printing equipment, misalignment can cause collisions or abnormal contact between the print head and paper products, damaging the print head. Position conversion systems ensure the accurate position of the paper during the printing process, reducing the possibility of such damage, lowering equipment repair and replacement costs, and further reducing production costs.

[0044] This automated position adjustment function can also be controlled through an intuitive user interface. Operators can easily view the paper position information on the control panel and make simple parameter settings as needed, such as adjusting the position adjustment accuracy and speed, which further simplifies the operation process and improves the convenience of operation.

[0045] The position conversion system can be integrated with sensor mechanism 7 and control system to achieve intelligent paper processing. For example, in conjunction with paper thickness sensors and tension sensors, the system can dynamically adjust the position conversion strategy according to the actual characteristics of the paper. If the paper thickness changes, the system can automatically adjust the force and angle to ensure position accuracy. Simultaneously, the position conversion system can collect and analyze paper position data, providing valuable information for production management. Through the analysis of large amounts of data, patterns of paper position deviation can be discovered, such as deviations that are prone to occur under specific processing speeds, paper types, or environmental conditions. This allows for further optimization of the processing process, achieving intelligent production management and improving the enterprise's production management level and competitiveness. The position conversion system described in this device is a collective term for all devices capable of changing the position of a product. The control system is integrated into the system, circuitry, and data of this device.

[0046] During product processing, positional deviations can lead to inaccurate cutting dimensions and misaligned printing patterns, resulting in a large number of defective products. By designing a positional conversion mechanism, paper positional deviations can be corrected in real time, ensuring that each processing step accurately targets the correct position on the paper. For example, in greeting card printing, if the paper is misaligned, the originally exquisite patterns and text may be printed on the edge of the card or even beyond the card's designated area, rendering the card unsellable. Precise positional adjustment ensures that the patterns and text are perfectly positioned on the card, significantly reducing the number of defective products caused by positional deviations and improving the product pass rate.

[0047] For multi-layered paper products, such as certain high-grade packaging papers, misalignment can cause the layers to malfunction, affecting the paper's strength and appearance. A positional adjustment system can precisely adjust each layer to its correct position, ensuring uniform quality of the laminated paper, avoiding defects caused by alignment issues, and improving overall production quality.

[0048] In traditional paper processing, frequent manual checks and adjustments are often required to avoid positional shifts, which severely impacts processing speed. With a position conversion design, the position can be automatically and quickly adjusted during high-speed transport of paper and other products, reducing processing interruptions caused by manual intervention. For example, on a high-speed production line, paper is prone to positional shifts during rapid transport, but the position conversion system can quickly correct this, making the production process smoother and increasing output per unit time.

[0049] This automatic position adjustment function also allows for better collaboration with other processing equipment. In integrated paper printing and cutting machines, the position conversion system ensures that the paper enters the cutting stage in the accurate position after printing, reducing waiting time between machines and making the entire processing flow more compact and efficient, thereby improving production efficiency.

[0050] Preferably, the lifting mechanism 3 includes a lifting base 31, a lifting rod 32, a lifting hydraulic cylinder 33, and a lifting bracket 34. There are two lifting bases 31, which are symmetrically arranged on both sides of the belt conveyor 1 and located on the ground. The lifting rod 32 is arranged on one of the lifting bases 31, and the lifting hydraulic cylinder 33 is arranged on the other lifting base 31. The lifting rod 32 and the lifting hydraulic cylinder 33 are symmetrically arranged. There are two lifting brackets 34, which are symmetrically arranged on corresponding lifting bases 31. The telescopic end of the lifting hydraulic cylinder 33 passes through the corresponding lifting bracket 34, and the telescopic end of the lifting rod 32 passes through the corresponding lifting bracket 34.

[0051] During the conveying operation of the product via the belt conveyor 1, the rotation frequency and speed of the rotary motor 51 are adjusted to match the conveying speed of the product via the belt conveyor 1. Then, the lifting hydraulic cylinder 33 drives the fixed shell 43 on the telescopic end of the hydraulic cylinder to move downward. The lifting rod 32 is in a coordinated telescopic state, which drives the surrounding position conversion mechanism 4 to move downward. The downward movement of the surrounding position conversion mechanism 4 drives the rotating mechanism 5 to move downward. The downward movement of the rotating mechanism 5 drives the auxiliary pressing mechanism 6 to move downward, which in turn drives several pressing rollers 64 to move downward, that is, to move towards the product. This causes the pressing rollers 64 to press against the product, thereby preventing the product from shifting position during the conveying operation via the belt conveyor 1. The lifting mechanism 3 is always in a coordinated operating state, and the height of the pressing rollers 64 is adjusted according to the product conveying situation, that is, the tightness of the pressing rollers 64 against the product is adjusted in real time.

[0052] Preferably, the rotating mechanism 5 includes a rotating motor 51, a rotating frame 52, a rotating shaft 53, a first transmission assembly 54, and a second transmission assembly 55. The rotating motor 51 is disposed inside the surrounding ring 42, and the rotating frame 52 is disposed inside the surrounding ring 42. The output end of the rotating motor 51 passes through the rotating frame 52 and is rotatably connected. The rotating shaft 53 is disposed on the output end of the rotating motor 51. The first transmission assembly 54 and the second transmission assembly 55 have the same structure. The auxiliary pressing mechanism 6 includes a first shaft 61, a second shaft 62, a third shaft 63, and a pressing roller 64. The first shaft 61, the second shaft 62, and the third shaft 63 are equidistantly arranged and are all rotatably connected to the inner wall of the surrounding ring 42. The pressing roller 64 is provided with several... The pressing rollers 64 are arranged in three groups, and the three groups of pressing rollers 64 are respectively sleeved on the first shaft 61, the second shaft 62 and the third shaft 63. The second shaft 62 is connected to the rotating shaft 53. The first transmission assembly 54 includes a driving wheel 541, a driven wheel 542 and a belt 543. The driving wheel 541 is sleeved on the rotating shaft 53, the driving wheel 541 is arranged on the second shaft 62, the driven wheel 542 is sleeved on the third shaft 63, and the belt 543 is sleeved on the driving wheel 541 and the transmission wheel. The driving wheel 541 in the second transmission assembly 55 is sleeved on the second shaft 62, and the driven wheel 542 in the second transmission assembly 55 is sleeved on the first shaft 61. The rotary motor 51 is a DC motor.

[0053] After the inductive sensor 73 detects the metal markings or magnetic materials on the product and the color mark sensor 72 accurately identifies the color markings on the product, if the positions of the inductive sensor 73 and the corresponding metal markings on the product match, then the operation is normal and can continue. If an error is detected, and the color information of the color mark position set on the product is matched with the position detected by the color mark sensor 72, then the operation is normal and can continue. If an error is detected, it proves that the product has shifted position during placement or transportation, which will affect the accuracy of product manufacturing. At this time, the operation of the lifting hydraulic cylinder 33 drives several pressing rollers 64 to press onto the required product. Then, according to the degree and direction of the product's positional shift, the drive motor 45 drives the circular gear 44 on the output end of the drive motor 45 to rotate. The rotation of the circular gear 44 drives the circular ring 42 to rotate, which changes the direction of the rotating mechanism 5. This allows for adjustment to a matching direction according to the required shift direction. Then, the rotation motor 51 drives... The rotating shaft 53 rotates, which drives the first transmission component 54 and the second transmission component 55 to rotate synchronously in one direction. This, in turn, drives the first shaft 61, the second shaft 62, and the third shaft 63 to rotate synchronously, ultimately driving several pressing rollers 64 to rotate. The rotation of the pressing rollers 64 can change the position of the product. For example, if several rollers rotate towards the hot stamping and die-cutting equipment 2, it means that the front of the product has moved out of the working position. If the direction of the hot stamping and die-cutting equipment 2 is taken as 30 degrees and the rollers rotate in the opposite direction, it means that the product position has deviated by 30 degrees and the front position has not reached the required working position. In summary, depending on different directions and distances, the auxiliary pressing mechanism 6, the rotating mechanism 5, the surrounding position conversion mechanism 4, and the lifting mechanism 3 can work together to adjust the position of the product to accurately carry out subsequent processing operations. Defective products caused by positional deviations mean waste of raw materials. The auxiliary pressing mechanism 6, the rotating mechanism 5, the surrounding position conversion mechanism 4, and the lifting mechanism 3 all have intelligent systems.

[0054] An electronic registration and correction device and method based on hot stamping and die-cutting process, comprising the following steps:

[0055] S1: When the product is hot stamping and die-cutting, the belt conveyor 1 drives the product to be transported. When the product is transported to the underside of the auxiliary pressing mechanism 6, the distance adjustment of the lifting mechanism 3 allows the auxiliary pressing mechanism 6 to press onto the product, which plays a supporting role in preventing the product from shifting during operation.

[0056] S2: Before the product is transported to the hot stamping and die-cutting processing equipment 2 for operation, in order to ensure the product processing position is accurate and prevent deviation, the sensor mechanism 7 accurately monitors the product position and the photoelectric sensor 71 detects whether the product has moved to the required detection position to check whether the product position is correct.

[0057] S3: After the product is detected by the photoelectric sensor 71, the thickness and number of sheets of the product are detected by the ultrasonic sensor 74. Utilizing the characteristics of ultrasonic waves propagating in different media, when the product passes through the sensor, the propagation time and intensity of the ultrasonic waves will change. The sensor judges the thickness and number of sheets of the product based on these changes. If the number of sheets is greater than one, it is judged to be incorrect, and an alarm is triggered.

[0058] S4: The material and humidity of the product are detected by the capacitance sensor 75. The capacitance sensor 75 can detect changes in the material and humidity of the product based on the dielectric constant of the product. If the detected product is unqualified, it is judged to be wrong and an alarm is triggered.

[0059] S5: The inductive sensor 73 detects metal markings or magnetic materials on the product. The inductive sensor 73 detects these markings or magnetic materials by sensing changes in the magnetic field. The position of the inductive sensor 73 matches the position of the corresponding metal marking on the product. If the positions match, the operation is normal and can continue. If an error is detected, the auxiliary pressing mechanism 6, rotating mechanism 5, surrounding position conversion mechanism 4, and lifting mechanism 3 work together to adjust the product's position.

[0060] S6: The color mark sensor 72 accurately identifies the color markings on the product. It is specifically designed to detect specific color markings on the product and has high color recognition accuracy and stability. The color mark sensor 72 can accurately detect the position and color information of the color mark on the product according to the preset color parameters, providing accurate positioning signals for subsequent printing, cutting, packaging and other processes. After the color information of the color mark position set on the product corresponds to the position detected by the color mark sensor 72, that is, the two positions match, it is normal and the operation can continue. If there is an error, the auxiliary pressing mechanism 6, the rotating mechanism 5, the surrounding position conversion mechanism 4 and the lifting mechanism 3 work together to adjust the position of the product.

Various modifications and variations can be made to the present invention by those skilled in the art.

7. A method for correcting the alignment of an electronic registration and correction device based on hot stamping and die-cutting process according to any one of claims 1-6, characterized in that, The correction method includes the following steps: S1: When the product is hot stamping and die cutting, the belt conveyor (1) drives the product to be transported. When the product is transported to the underside of the auxiliary pressing mechanism (6), the distance adjustment of the lifting mechanism (3) allows the auxiliary pressing mechanism (6) to press onto the product, which plays a role in assisting and preventing the product from shifting during operation. S2: Before the product is transported to the hot stamping and die-cutting equipment (2) for operation, in order to ensure the product processing position is accurate and prevent deviation, the product position is accurately monitored by the sensor mechanism (7), and the photoelectric sensor (71) is used to detect whether the product has moved to the required detection position and check whether the product position is present. S3: After the product is detected by the photoelectric sensor (71), the thickness and number of sheets of the product are detected by the ultrasonic sensor (74). The characteristics of ultrasonic waves propagating in different media are utilized. When the product passes through the sensor, the propagation time and intensity of the ultrasonic waves will change. The sensor judges the thickness and number of sheets of the product based on these changes. If the number of sheets is greater than one, it is judged to be wrong and an alarm is triggered. S4: The material and humidity of the product are detected by the capacitance sensor (75). The capacitance sensor (75) can detect the changes in the material and humidity of the product based on the dielectric constant of the product. If the detected product is unqualified, it is judged to be wrong and an alarm is triggered. S5: The inductive sensor (73) detects the metal markings or magnetic materials on the product. The inductive sensor (73) can detect these markings or materials by sensing changes in the magnetic field. The position of the inductive sensor (73) matches the position of the corresponding metal marking on the product. In other words, if the two positions match, it is normal and the operation can continue. If there is an error, the product position is adjusted by cooperating with the auxiliary pressing mechanism (6), the rotating mechanism (5), the surrounding position conversion mechanism (4), and the lifting mechanism (3). S6: The color mark sensor (72) accurately identifies the color mark on the product. It is specifically used to detect the specific color mark on the product and has high color recognition accuracy and stability. The color mark sensor (72) can accurately detect the position and color information of the color mark on the product according to the preset color parameters, and provide accurate positioning signals for subsequent printing, cutting and packaging processes. After the color information of the color mark position set on the product corresponds to the position detected by the color mark sensor (72), that is, the two positions match, it is normal and the operation can continue. If there is an error, the auxiliary pressing mechanism (6), the rotating mechanism (5), the surrounding position conversion mechanism (4) and the lifting mechanism (3) are used to coordinate the operation to adjust the position of the product.
