Description

Technical Field

[0001] This utility model relates to the technical field of aseptic packaging printing production equipment, specifically a high-speed safety indentation and punching process connection device for aseptic packaging printing lines. Background Technology

[0002] In the printing production of aseptic packaging, such as aseptic paper-plastic composite films for food and pharmaceutical packaging, creasing and punching are critical processes that directly affect the subsequent forming and sealing quality. As market demands for production efficiency increase, printing line speeds have gradually exceeded 600 m / min. However, existing creasing and punching devices suffer from the following problems: at high speeds, paper is prone to deviation (width direction) or registration error (longitudinal direction), leading to creasing and punching position misalignment and a high scrap rate; the creasing and punching process is noisy, operators are prone to accidentally touching high-speed rotating parts, and there is significant accumulation of punching waste and paper dust contamination; mold adjustments require machine shutdowns, and waste accumulation leads to frequent speed reductions, making it unsuitable for high-speed production lines. Therefore, a high-speed, safe inline device for the creasing and punching process on aseptic packaging printing lines is needed.

[0003] According to the search, Chinese application number CN201420406786.2 discloses a punching and creasing device for ampoule packaging boxes. This utility model can meet the automatic punching and creasing needs of ampoule packaging boxes of different specifications, and improve production efficiency. The above-mentioned device has the following shortcomings: When the traditional device is in use, the tension of the packaging paper fluctuates greatly when it is at high speed, changes in roll diameter, or when it accelerates or decelerates, which can easily lead to stretching deformation or tearing, affecting product quality, making the device tension unstable, and reducing the working efficiency of the device.

[0004] To address the aforementioned issues, the development of an indentation and punching connection device capable of operating at speeds above 600 m / min and possessing precision, stability, and safety has become an urgent industry need. Utility Model Content

[0005] The purpose of this utility model is to provide a high-speed safety indentation and punching process connection device on an aseptic packaging printing line. By using this device, the problem of large tension fluctuations in packaging paper during high-speed operation, changes in roll diameter, or acceleration and deceleration in traditional devices is solved. This leads to stretching deformation or tearing, affecting product quality, and causing unstable tension in the device, thus reducing the working efficiency of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed safety indentation and punching process connection device for aseptic packaging printing line, comprising a fully automatic paper path correction system, a paper feed force control system, a longitudinal registration system, a paper cutter, a mold assembly, a paper path stabilizing roller, a vacuum waste collection system, and an output paper force stabilizing system arranged sequentially along the paper path direction, as well as a soundproof isolation chamber for accommodating the mold assembly and the paper path stabilizing roller, and further comprising a cantilever operation screen and an electrical control cabinet; the mold assembly includes a mold base and at least three indentation and punching mold stations, and the electrical control cabinet is electrically connected to each of the above systems to achieve coordinated control, and the device line speed can reach more than 600m / min; the mold assembly and the paper path stabilizing roller are located in the soundproof isolation chamber, the cantilever operation screen is electrically connected to the electrical control cabinet, and the electrical control cabinet is electrically connected to each system.

[0007] Preferably, the fully automatic paper path correction system can automatically correct material deviation in a high-speed production line, ensure the accuracy of the embossing and punching position in the width direction of the material, reduce waste and defective products caused by deviation, avoid frequent machine stops for adjustment caused by deviation, and prevent the material from excessively deviating and scraping the side wall of the equipment or getting caught in the roller.

[0008] With the above-mentioned structural design, the fully automatic paper path correction system is the key to achieving high-speed and stable production, as manual intervention is impossible on high-speed production lines.

[0009] Paper feed tension control: Ensuring that the printing paper maintains a stable and appropriate tension under various operating conditions such as high-speed operation, changes in roll diameter, acceleration, and deceleration is crucial for guaranteeing product quality, improving production efficiency, and protecting equipment safety. Placing this control on the paper feed side avoids tension instability caused by upstream processes, which could negatively impact production. Preferably, the paper feeding force control system is located on the paper feeding side, which can ensure that the printing paper bears stable and appropriate tension under conditions such as high-speed operation, roll diameter change, acceleration and deceleration, and avoid the instability of tension caused by the previous process affecting production.

[0010] The design employs the above-described high-precision synchronous tension control mechanism. A rack and pinion system ensures horizontal synchronization of the tension rollers, while a servo proportional valve precisely controls the air pressure to achieve the required paper tension. The horizontal rollers move up and down, providing feedback on the tension level. Simultaneously, the paper extension and retraction main shaft traction mechanism uses cylinder extension pressure to increase the pressure between the rubber-coated pressure roller and the traction roller via levers, thereby increasing friction. Subtle changes in linear velocity allow for fine-tuning of the tension, stabilizing it. The front and back sides of the paper contact water-circulating cooling rollers A and B respectively, stabilizing paper temperature, controlling paper elongation, and contributing to tension control. Longitudinal registration system: Real-time detection and automatic adjustment of indentation and punching, and the relative position of the pattern in the paper running direction (longitudinal direction); Paper cutter: In emergency situations during online operation, it cuts off the high-speed paper path to ensure the safety of the creasing and punching mold and prevent it from being scrapped due to excessive paper wrapping; Mold base: It has the function of quickly and efficiently positioning the mold. During the production process, the lateral position of the mold can be adjusted without stopping the machine, avoiding the reduction in production efficiency caused by frequent machine stops for adjustment.

[0011] Preferably, the paper feeding force control system includes a high-precision synchronous tension control mechanism. The mechanism uses a gear rack to ensure the horizontal synchronous movement of the tension roller, and uses a servo proportional valve to precisely control the air pressure to obtain the required paper tension. The horizontal roller can move up and down to provide feedback on the tension magnitude and compensate for paper expansion and contraction.

[0012] The above-mentioned structural design, with its mold station and ultra-high precision molds, is key to stable and high-speed production. The three-station mold combination can meet 95% of the market's product needs. Paper path stabilizing roller: Adjustable horizontally and vertically. Placed between the dies at each workstation, it stabilizes the paper path and prevents interference between workstations during operation. Soundproof isolation room: Equipped with an alarm light system, lighting system, safety isolation door, air conditioning system, and fresh air system. It absorbs high-decibel indentation and punching noise, provides high-speed air exchange, and isolates a safe and clean area. This prevents accidental contact during production, ensuring both operator safety and a clean production process.

[0013] Preferably, the paper feeding force control system further includes a main shaft traction mechanism. The mechanism uses the extension pressure of the cylinder to increase the pressure between the coated pressure roller and the traction roller through the lever to increase the friction force, and uses the slight change in linear velocity to fine adjust the tension. The main shaft traction mechanism includes a paper pressing cylinder, a force-applying lever, a traction main shaft, a coated pressure roller, a water-circulating cooling roller A, a water-circulating cooling roller B, and a paper feed roller. The cylinder drives the lever to increase the pressure of the pressure roller, and the front and back sides of the paper contact the water-circulating cooling roller A and the water-circulating cooling roller B respectively to stabilize the paper temperature and control the paper elongation.

[0014] The vacuum waste collection system, designed with the above structure, features a high-powered suction fan that rapidly removes waste generated during the punching process, preventing excessive waste accumulation and speed reduction. It is also equipped with a dust collector to absorb and filter paper dust generated during punching, and discharges clean air to ensure a safe production environment.

[0015] Preferably, the longitudinal registration system can detect and automatically adjust the relative positions of the indentation and punching patterns in the longitudinal direction of paper movement in real time, and achieve longitudinal registration accuracy control by identifying the indentation calibration line.

[0016] The paper tension stabilization system, designed with the above structure, maintains paper tension and eliminates the potential for tension instability caused by indentation and punching, which is one of the keys to the high-speed operation of the entire machine.

[0017] Preferably, the mold assembly has the function of quickly and efficiently positioning the mold, and can adjust the lateral position of the mold without stopping the machine during production, so as to avoid the reduction in production efficiency caused by frequent machine stops for adjustment.

[0018] With the above-described structure, the cantilever control panel allows for external operation of equipment alignment, tension settings, etc. The cantilever also enables convenient and quick movement of the display screen, and the remote touchscreen eliminates the need for close-range equipment operation, ensuring safety.

[0019] Preferably, the paper path stabilizing roller is disposed between each indentation and punching die station, and can be adjusted in the horizontal and vertical directions to stabilize the paper path and avoid mutual interference during operation of each station.

[0020] With the above-mentioned structural design, the brain and power source of the entire indentation and punching system of the electrical control cabinet are separated into strong and weak currents, air conditioning is provided for cooling, and all control cables are equipped with shielding layers, eliminating all adverse factors.

[0021] Preferably, the soundproof isolation room is equipped with an alarm light system, a lighting system, a safety isolation door, an air conditioning system, and a fresh air system, which can absorb the high-decibel noise generated by the indentation and punching, achieve high-speed air exchange, and isolate a safe and clean area to ensure the safety of operators and the cleanliness of the production environment.

[0022] The above-mentioned structural design ensures precision: guaranteeing the accuracy of the material width direction in the indentation and punching position; and improves product quality: reducing scrap and defective products caused by deviation.

[0023] Preferably, the vacuum waste collection system includes a high-powered suction fan and a dust collector. The suction fan can suck away the waste generated during the punching process at high speed to avoid accumulation and slowing down, while the dust collector can absorb and filter the paper dust generated during punching and discharge clean air.

[0024] The above-mentioned structural design improves production efficiency by avoiding frequent downtime for adjustments due to misalignment and protects equipment safety by preventing excessive material deviation from scraping the equipment sidewalls or getting caught in the rollers, which could lead to material tearing, equipment wear, or even damage.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The device, through the synergistic effect of fully automatic paper path correction (width direction), longitudinal alignment (longitudinal direction) and full-process tension control, can still ensure the creasing and punching accuracy (±0.1mm) at high speed, reduce the scrap rate, and has the characteristics of high speed and high precision. 2. The paper feeding and output paper force control system of the device, together with the paper path stabilizing roller, effectively suppresses paper expansion and contraction deformation, and reduces tension fluctuations under conditions such as changes in roll diameter and acceleration and deceleration. This improves the stability of continuous operation of the equipment and achieves high stability of the device. 3. The soundproof isolation room of the device reduces noise, the remote operation panel and paper cutter avoid the risk of personnel contact, and the vacuum waste collection system achieves zero waste accumulation and efficient paper dust filtration, improving the working environment and achieving high safety and environmental protection of the equipment. 4. The mold base of the device can be adjusted without stopping the machine and the three-station combination design reduces downtime, adapts to the needs of high-speed production lines, and achieves high efficiency of the device.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: The fully automatic paper path correction system 1 can automatically correct material deviation in high-speed production lines, ensuring the accuracy of the embossing and punching positions in the width direction of the material, reducing waste and defective products caused by deviation, avoiding frequent machine stops for adjustment due to deviation, and preventing excessive material deviation from scratching the side wall of the equipment or getting caught in the rollers.

[0033] The paper feeding force control system 2 is located on the paper feeding side, which can ensure that the printing paper is subjected to stable and appropriate tension under conditions such as high-speed operation, roll diameter change, acceleration and deceleration, and avoid the instability of tension caused by the previous process affecting production.

[0034] The paper feeding force control system 2 includes a high-precision synchronous tension control mechanism. The mechanism uses gears and racks to ensure the horizontal synchronous movement of the tension roller. It precisely controls the air pressure through a servo proportional valve to obtain the required paper tension. The horizontal roller can move up and down to provide feedback on the tension magnitude and compensate for paper expansion and contraction.

[0035] The paper feeding force control system 2 also includes a main shaft traction mechanism. The mechanism uses the extension pressure of the cylinder to increase the pressure between the coated pressure roller 18 and the traction roller through the lever to increase the friction force, and uses the slight change in linear velocity to fine adjust the tension.

The cylinder drives the lever to increase the pressure of the pressure roller, and the front and back sides of the paper contact the water-circulating cooling roller A19 and the water-circulating cooling roller B20 respectively to stabilize the paper temperature and control the paper elongation.

[0037] Mold assembly 5 has the function of quickly and efficiently positioning the mold, and can adjust the lateral position of the mold without stopping the machine during production, so as to avoid the reduction in production efficiency caused by frequent machine stops for adjustment.

[0038] The paper path stabilizing roller 7 is set between each creasing and punching die station and can be adjusted horizontally and vertically to stabilize the paper path and avoid mutual interference during operation of each station.

The suction fan can suck away the waste generated during the punching process at high speed to avoid accumulation and slowing down. The dust collector can absorb the paper dust generated during the punching process and discharge clean air.

[0041] In summary, the working principle is as follows: The fully automatic paper path correction system 1 is set at the paper path input end to detect the paper width direction deviation in real time and automatically adjust it to ensure the accuracy of the creasing / punching position in the width direction; it is linked with the servo drive mechanism through photoelectric sensors, with a response speed of ≤5ms and a correction accuracy of ±0.1mm.

[0042] Paper feed force control system 2: Located downstream of the fully automatic paper path correction system 1, it includes a high-precision synchronous tension control mechanism: the tension roller is driven to move horizontally synchronously through a gear rack, and the air pressure is precisely controlled by a servo proportional valve to achieve a stable tension control accuracy of ±1N; Main shaft traction mechanism: It consists of a rubber-coated pressure roller 18, a traction roller and water-circulating cooling rollers A and B. The pressure of the pressure roller is increased by a cylinder-driven lever, and the tension fluctuation is compensated by fine adjustment of the linear speed. At the same time, the cooling roller controls the paper temperature ±2℃ to suppress expansion and contraction. Longitudinal registration system 3: Located downstream of the paper feeding force control system 2, it identifies the indentation calibration line on the paper through an image sensor, calculates the longitudinal position deviation in real time, and drives the servo motor to adjust the mold position, with a registration accuracy of ±0.05mm. Paper cutter 4: Located between the longitudinal alignment system 3 and the mold station, it quickly cuts off the paper path in emergency situations such as paper entanglement or excessive deviation, protecting the mold from damage; Mold assembly: including mold base and three sequentially arranged indentation / punching mold stations No. 1, No. 2 and No. 3; the mold base has a horizontal non-stop adjustment function with an adjustment accuracy of ±0.03mm. The three-station mold combination can cover more than 95% of the needs of aseptic packaging products. Paper path stabilizing roller 7: Located between each mold station, it can be adjusted horizontally and vertically to stabilize the paper path and avoid mutual interference during operation of adjacent stations, such as positional displacement caused by vibration transmission. Soundproof isolation room: It encloses the mold components and paper path stabilizing roller 7, and has built-in alarm lights, lighting, safety isolation doors, air conditioning and fresh air system; its inner wall is made of sound-absorbing cotton with a noise reduction of ≥30dB, while forming a clean isolation space with a cleanliness level of ≥100,000 to prevent personnel from accidentally touching environmental dust pollution; Vacuum waste collection system 11: includes a high-power suction fan with a wind pressure ≥20kPa, waste pipes and a dust collector; the suction fan sucks away the punching waste at high speed through the suction port below the mold station, and the dust collector has a filter paper dust filtration efficiency of ≥99.5% to ensure that the exhaust air is clean; Paper output force stabilization system 12: Located at the paper output end, its structure is adapted to the paper feed force control system 2. It is used to eliminate tension fluctuations caused by the creasing / punching process and ensure that the paper enters the next process with stable tension. Control and electrical system: including cantilever operation panel 13 and electrical control cabinet 14; the cantilever operation panel 13 can remotely adjust the alignment parameters, tension value and other operating distance ≥1.5m to avoid personnel from coming into close contact with dangerous areas; the electrical control cabinet 14 adopts a strong and weak current separation design, and is equipped with air conditioning cooling and shielded cables to ensure circuit stability during high-speed operation.

[0043] Overall structure: like Figure 1 As shown, this device includes, in sequence along the paper path direction: a fully automatic paper path correction system 1, a paper feed force control 2, a longitudinal alignment system 3, a paper cutter 4, a mold base 5, a first-order creasing / punching mold station 6, a paper path stabilizing roller 7, a second-order creasing / punching mold station 8, a third-order creasing / punching mold station 7, a vacuum waste collection system 11, and an output paper force stabilizing system 12; the mold assembly and the paper path stabilizing roller 7 are located inside a soundproof isolation room 9, with an external cantilever operation panel 13 and an electrical control cabinet 14.

[0044] Working process of each component: Fully automatic paper path correction system 1: After the paper enters, the photoelectric sensor detects the edge position in real time. When the offset exceeds 0.1mm, the servo motor drives the correction roller to rotate and adjust the paper position to ensure the accuracy in the width direction.

[0045] Paper feed force control system 2: The high-precision synchronous tension control mechanism ensures the horizontal synchronous movement of the tension roller through a gear and rack mechanism. The servo proportional valve adjusts the air pressure according to the preset tension value, and the up-and-down movement of the tension roller provides real-time tension feedback to compensate for paper expansion and contraction. In the main shaft traction mechanism, the cylinder increases the pressure between the coated pressure roller 18 and the traction roller through the lever, and uses the linear speed fine adjustment to compensate for tension fluctuations; the water circulation cooling rollers A19 and B contact the front and back sides of the paper respectively, stabilize the temperature at 25±2℃, and suppress thermal deformation.

[0046] Longitudinal registration system 3: The image sensor captures the indentation calibration line on the paper and compares it with the preset position. If the deviation exceeds 0.05mm, the servo motor drives the mold to make fine adjustments along the longitudinal direction to ensure the longitudinal relative position accuracy of the indentation / punching and the printed pattern.

[0047] Die assembly operation: After the paper enters the die station, dies No. 1, No. 2 and No. 3 complete the creasing / punching operations in sequence (e.g., No. 1 does longitudinal creasing, No. 2 does transverse creasing, and No. 3 makes positioning holes); the die base 5 can be adjusted in the transverse position of the die during production without stopping the machine by handwheel or electric drive to adapt to different paper widths.

[0048] Paper path stabilizing roller 7: It is fixed between each mold station by bearing seats, and the horizontal angle (±5°) and longitudinal height (±10mm) can be manually adjusted to counteract the vibration during mold operation and stabilize the paper path trajectory.

[0049] Safety and environmental control: The soundproof isolation room 9 absorbs the noise from the indentation and punching through sound-absorbing cotton, the air conditioner maintains the internal temperature at 20-25℃, and the fresh air system changes the air 15 times per hour to ensure cleanliness; the safety isolation door is equipped with an infrared sensor, and the equipment automatically slows down to a stop when the door is opened. The vacuum waste collection system 11's suction fan starts the moment the mold is punched. The waste is sucked into the pipe through the suction port (5-10mm in diameter) under the mold. After being filtered by the dust collector, the clean air is discharged and the waste is collected in a sealed box (an alarm light indicates replacement when the box is full).

[0050] Paper output force stabilization system 12: It adopts the same structure as the paper feed force control system 2, eliminates local tension abrupt changes caused by indentation / punching, and ensures that the paper enters the next process with stable tension (deviation from the paper feed force ≤3%).

[0051] Operation: Operators can set tension values, alignment parameters, etc. through the cantilever control panel 13 (which can rotate 360° and move within a 2m radius around the equipment). The PLC in the electrical control cabinet 14 processes the signals from various sensors in real time and drives the actuators to achieve fully automated control.
