Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a coiled material cutting machine with a cutting blade automatic replacement function. Background Art

[0002] Coil cutting machines are widely used in industrial production to cut large coils into sheets or strips of varying sizes as needed. While traditional coil cutting machines can meet basic cutting requirements, they still present operational challenges. An existing waste-reducing coil cutting machine (publication number: CN211003855U) suffers from the following drawbacks, requiring further improvement.

[0003] 1. Traditional equipment does not have the function of automatic tool replacement, so tool replacement relies entirely on manual operation. The operator needs to monitor the status of the tool at all times during the cutting process, and when the tool is worn and needs to be replaced, the machine must be manually shut down. The tool replacement process after shutdown is cumbersome, requiring the worn tool to be removed, the new tool to be reinstalled, and then adjustments and debugging to ensure cutting accuracy. This series of operations is time-consuming and directly affects the continuity and efficiency of production. In large-scale, high-frequency production lines, frequent shutdowns to change tools not only extend the production cycle, but also increase labor costs. If the tool is not replaced in time, the cutting quality will be reduced, and even material waste and equipment damage will occur. Therefore, there is an urgent need for a cutting machine with automatic tool replacement function.

[0004] 2. Traditional equipment does not have a dedicated waste disposal function. Waste generated during the cutting process, such as scraps and debris, will directly accumulate near the equipment or be scattered on the workbench. This increases the burden of cleaning work, affects the cleanliness of the operating area, and even poses a hidden danger to safe operation in some cases. In traditional equipment without a sliding waste collection function, operators need to stop the machine regularly to manually clean the waste. This process is time-consuming and labor-intensive, especially when cutting a large number of coils. The waste cleaning work becomes even more cumbersome. Since waste is not centrally handled, it is easy to accumulate inside or around the equipment. If it is not cleaned for a long time, it may affect the normal operation of the equipment and even cause equipment failure. Waste accumulation in the transmission components or cutting area will cause mechanical jamming or uneven cutting, thus affecting the smoothness of the entire production process. Therefore, there is an urgent need for a cutting machine with a sliding waste collection function.

[0005] 3. Traditional equipment has difficulty accurately estimating the remaining service life of a tool and relies on changes in cutting results to determine whether the tool needs to be replaced. This approach is not only inaccurate but also brings a series of problems. If the operator fails to detect tool wear in a timely manner, continued use of the tool will lead to a decrease in cutting accuracy, affecting the quality of the final product. In some high-precision production tasks, tool wear may lead to material waste or even scrap. Secondly, overused tools will damage the equipment itself and increase equipment maintenance costs. Due to the lack of a clear tool life management mechanism and the irregular tool replacement cycle, operators are prone to overlooking potential safety risks when maintaining the tool. Prolonged use of worn tools may increase safety hazards in production. Therefore, there is an urgent need for a cutting machine with a tool life reminder function. Utility Model Content

[0006] The main purpose of the utility model is to provide a coil cutting machine with an automatic cutting blade replacement function, which can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: there is a coil cutting machine with the function of automatic replacement of cutting tools, a cutting main unit is installed above the base plate, a driving device is installed above the cutting main unit, a main cutter head is installed on one side of the base plate, a mechanical arm is installed on one side of the main cutter head, a controller is installed on one side of the mechanical arm, a secondary cutter head is installed on one side of the controller, and a waste collection box is installed above the base plate.

[0008] Preferably, a counter is installed above the waste collection box, an infrared sensor is installed above the counter, and a display is installed on one side of the counter.

[0009] Preferably, the outside of the bottom plate adopts a rounded corner design.

[0010] Preferably, the primary cutting head is rotatable via an internal shaft.

[0011] Preferably, there are several bolt holes below the cutting main unit.

[0012] Preferably, the waste collection box is designed to be detachable.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By incorporating a robotic arm, primary and secondary cutter heads, and a controller, this utility model can rapidly replace the primary cutter head with a secondary cutter head when it reaches a preset wear level. The entire process is precisely controlled by the controller, ensuring accurate and stable replacement. This eliminates the need for operators to frequently monitor tool status, reducing the potential for human error. Furthermore, the automatic tool replacement function allows for uninterrupted operation during the production process, significantly improving production efficiency. This is particularly true in large-scale, high-intensity production environments, allowing production lines to operate continuously and shortening production cycles.

[0015] 2. The utility model adds a waste collection box, which can automatically enter the collection box during the cutting process, and the sliding design allows the operator to easily pull it out for dumping and cleaning. The biggest advantage of this design is that it can centrally process waste, keep the work area tidy, reduce the accumulation of debris around the equipment, and effectively avoid equipment failure and production interruptions caused by waste accumulation. In addition, the sliding design also makes the waste cleaning process more efficient, and operators no longer need to frequently stop the machine for manual cleaning, thereby saving valuable production time. When cutting a large number of coils, the amount of waste is large, and the cleaning burden of traditional equipment is particularly prominent. Through the waste collection box, these wastes can be processed quickly and centrally, greatly reducing the time and energy required for cleaning work, ensuring the smoothness of the production process, and reducing the maintenance cost of the equipment.

[0016] 3. The present invention can monitor the use of the tool in real time by adding an infrared sensor, a counter, and a display. The counter records the number of times each cutting operation is performed, and through a preset threshold, when the number of times the tool is used reaches a predetermined value, the display issues a reminder to inform the operator that the tool needs to be replaced. This design ensures that the service life of the tool is within a controllable range, which not only avoids the decline in cutting quality due to excessive use of the tool, but also protects the equipment from excessive wear, thereby extending the service life of the equipment. More importantly, the tool life reminder function provides operators with clear replacement instructions, reduces the uncertainty of relying on experience-based operations, and ensures safety and stability in the production process. In some production tasks that require high-precision cutting, timely replacement of tools is particularly critical to product quality. Therefore, this function can effectively improve the stability and consistency of production, avoid defective or waste products due to tool wear, and thus improve production efficiency and product qualification rate.

[0025] A coil cutting machine with an automatic cutting tool replacement function, wherein a cutting host 2 is installed above the base plate 1, a driving device 3 is installed above the cutting host 2, a main cutter head 4 is installed on one side of the base plate 1, a mechanical arm 5 is installed on one side of the main cutter head 4, a controller 6 is installed on one side of the mechanical arm 5, a secondary cutter head 7 is installed on one side of the controller 6, and a waste collection box 8 is installed above the base plate 1.

[0026] The following are specific implementations of the components of the utility model:

[0027] 1. Baseplate: The baseplate is the foundation of the entire machine, supporting and stabilizing all components. It is typically designed to be flat and sturdy to ensure the stability of the machine during operation. Several bolt holes are designed into the baseplate to secure the cutting machine and other components, ensuring the safety and stability of the machine.

[0028] 2. Cutting Machine: Mounted above the baseplate, the cutting machine is a core component of the machine, responsible for driving the cutting head. Powered by a drive unit, the cutting machine achieves precise cutting of the coiled material. Bolt holes located below the cutting machine are used to secure it, ensuring it remains stable during operation.

[0029] 3. Drive Unit: Mounted above the cutting machine, the drive unit is responsible for powering the cutting process. This unit typically uses a motor or hydraulic system to provide sufficient force to drive the cutter head to cut the material. The drive unit's mounting position ensures it can directly transmit power to the cutter head, ensuring precise cutting results.

[0030] 4. Main Cutting Head: Mounted to the side of the base plate, the main cutting head rotates on an internal axis to cut the material. This head is responsible for performing the cutting operation and is the part of the machine that comes into direct contact with the material. The rotating axis design of the cutting head ensures that the tool can complete the cutting task with high precision.

[0031] 5. Robotic Arm: The robotic arm is mounted on the side of the main cutting head and is mainly used to assist in the movement or replacement of the cutting tool. The robotic arm can automatically or manually adjust the angle or position of the cutting head by cooperating with the controller, thereby improving cutting efficiency and flexibility.

[0032] 6. Controller: Mounted on the side of the robotic arm, the controller controls the overall operation of the machine.

This counter helps operators better manage equipment maintenance and prevent degradation of cutting quality due to overuse of the tool.

[0036] 10. Infrared Sensor: Mounted above the counter, the infrared sensor monitors the tool's condition and usage. By monitoring tool wear and cutting performance, the infrared sensor accurately identifies when a tool needs replacement. This, combined with the counter, provides a tool life reminder, ensuring optimal equipment operation.

[0037] 11. Display: The display is installed on the side of the counter and is used to display the operating status of the equipment and the use of the tool in real time. By connecting the controller and sensor, the display can provide a clear operation interface, allowing operators to timely understand the working status of the equipment and ensure the smooth progress of the cutting process.

[0038] The following is a specific technical logic implementation method of the innovative point of this utility model:

[0039] 1. Technical logic implementation of automatic tool replacement function

[0040] The automatic tool replacement function of this utility model is achieved through the precise coordination of a robotic arm, primary cutter head, secondary cutter head, and controller. First, the controller uses sensors to monitor the usage of the primary cutter head in real time, particularly its wear status. When the cutter reaches a preset wear threshold, the controller issues a replacement command, triggering the robotic arm to operate. The robotic arm is fixed to one side of the device and has sufficient degrees of freedom to accurately position and perform the tool replacement task. During operation, the robotic arm first grasps the secondary cutter head and moves it to the designated tool position. It then removes the worn primary cutter head and moves it to a spare position. To ensure accurate tool replacement, the robotic arm is equipped with high-precision positioning sensors to ensure proper alignment of the cutter heads during replacement and reduce operational errors. The entire process is fully automated by the controller, ensuring smooth primary cutter head replacement and minimizing operator error. Furthermore, the secondary cutter head's mounting position and fixture are designed for quick assembly and disassembly, thereby increasing replacement speed. This function enables tool replacement without interrupting production, making it particularly suitable for large-scale, high-intensity production environments, ensuring continuous production line operation, reducing downtime, and improving production efficiency.

[0041] 2. Technical logic implementation of waste collection function

[0042] The core design of the waste collection function lies in the coordination of the waste collection box's sliding structure with the overall equipment. First, a guide mechanism is designed between the cutting area of ​​the equipment and the waste collection box to ensure that scraps and waste generated during the cutting process can smoothly enter the waste collection box. The waste collection box is located at the bottom of the equipment and mounted on a dedicated slide rail. It has a removable design. When the cutting operation begins, the waste generated by cutting naturally slides into the waste collection box through the guide plate inside the equipment. The slide rail design allows the waste collection box to be easily pulled out of the equipment, conveniently allowing the operator to clean it. The advantage of this design lies in its automatic waste disposal capability, which can maintain a clean work area while the equipment continues to operate. In addition, the sliding structure has locking and limit functions to ensure that the waste collection box does not move due to vibration during operation, which would affect waste collection. The waste collection box is easy to install and remove, and the operator can remove the waste box for cleaning as needed, reducing equipment downtime. Especially when cutting a large number of coils, waste accumulates quickly and traditional equipment needs to be frequently stopped for cleaning. This innovative design greatly reduces the cleaning frequency and optimizes the operating efficiency of the equipment while keeping the work area clean.

[0043] 3. Technical logic implementation of tool life reminder function

[0044] The tool life reminder function uses an infrared sensor, a counter, and a display to precisely monitor and remind operators of tool usage. First, an infrared sensor is installed in the cutting area to monitor tool usage and wear in real time. At the start of each cutting operation, the sensor detects whether the tool is in proper working order and transmits this data to the counter. The counter tracks tool usage by recording the number of cuts. When the tool usage reaches a preset threshold, the counter sends a signal to the controller, which triggers a replacement reminder on the display. The display visually reminds the operator that the tool needs to be replaced, thus preventing wear and damage caused by excessive use. Furthermore, the system can set different tool replacement thresholds based on the cutting requirements of different materials, ensuring that tool life is managed within a reasonable range. This intelligent monitoring and reminder eliminates the need for operators to rely on experience to determine tool status, reducing the possibility of misjudgment. The core logic of this technology ensures that tools are replaced at the appropriate time, preventing excessive tool wear from affecting cutting quality and reducing additional equipment maintenance costs. This function is particularly suitable for high-precision production tasks, ensuring consistent product quality and improving production efficiency and equipment reliability.

[0050] 5. Automatic tool replacement: When the primary cutter head is worn and needs to be replaced, the robotic arm starts and replaces the secondary cutter head with the primary cutter head. The entire replacement process is precisely controlled by the controller.

[0051] 6. Waste cleaning: During the cutting process, waste automatically enters the waste collection box. The operator can pull the waste box out of the slide rail according to the accumulation of waste, clean the waste and put it back.

[0052] 7. Tool life reminder: When the number of times the tool is used reaches the set threshold, the display will issue a reminder to replace the tool. The operator will replace the tool in time according to the prompt to avoid affecting the cutting quality due to excessive use of the tool.

[0053] 8. End of operation: After completing the cutting task, the operator turns off the power of the equipment and performs necessary equipment inspection and maintenance to ensure that the equipment is in good condition.
