[0024] Keel forming and cutting is a crucial step in the keel forming process, requiring high precision in shaping the keel. However, current production processes rely heavily on manual labor and have a low level of automation, which has become a major bottleneck restricting product development. To address these issues, this invention provides an automatic keel cutting system, aiming to overcome the shortcomings of low production efficiency and low automation in existing technologies. This system not only improves production efficiency and reduces manufacturing costs but also significantly enhances product quality and consistency, thereby promoting the further application and development of keel products in the building decoration field.

[0025] The following is combined Figures 1-3 This invention describes the specific implementation of the automatic keel cutting system.

[0026] like Figure 1As shown, this utility model provides an automatic keel cutting system, including: a first platform 100, on which a cutting device 110 and a first positioning device 120 are disposed, the first positioning device 120 being used to position the end of the keel, and a first positioning distance being between the cutting device 110 and the first positioning device 120; a second platform 200, adjacent to the first platform 100 and of the same height, the second platform 200 being provided with a punching device 210 and a conveying mechanism; the conveying mechanism being used to drive the keel through the punching device 210 and the cutting device 110 and convey it to the first platform 100 until the end of the keel is positioned by the first positioning device 120, the cutting device 110 being used to perform a cutting action on the keel at a distance from the first positioning device 120, and the punching device 210 being used to perform a punching action on the keel at its corresponding position. Specifically, this technical solution precisely controls the conveying mechanism to accurately convey the keel profile to a predetermined position and then stops, at which point one end of the keel is accurately positioned by the first positioning device 120. Subsequently, at the same workstation, the punching device 210 and the cutting device 110 work synchronously, completing the punching and cutting operations at preset positions respectively. This method not only improves processing efficiency but also ensures the accuracy and consistency of each processing step.

[0027] In practical applications, the aforementioned automatic keel cutting system enables a highly efficient and precise keel production process. For example, in the production of ceiling keels, once the keel is transported to the designated position and fixed, the punching and cutting processes are performed simultaneously, without the need for additional material movement or adjustment. This design significantly reduces the need for manual intervention, improving the overall efficiency of the production line and the consistency of product quality. Furthermore, in addition to basic punching and cutting functions, supplementary functions such as automatic detection systems can be added to monitor the quality during processing, ensuring that each finished product meets predetermined standards. Moreover, for keels of different specifications and sizes, the system can adjust parameter settings via software to flexibly adapt to various production needs, improving the equipment's versatility and practicality.

[0028] like Figure 2As shown, according to the present invention, an automatic keel cutting system includes a cutting device 110 comprising: a first frame 111 disposed on a first platform 100; a cutting die 112 disposed within the first frame 111 and located on the keel's conveying path; and a first drive cylinder 113 disposed on the first frame 111 for driving the cutting die 112 to perform opening and closing actions. Specifically, the cutting device 110 is powered by the first drive cylinder 113, driving the cutting die 112 to move up and down, thereby achieving precise cutting of the keel profile. The structure of the cutting die 112 matches the cross-sectional shape of the keel, ensuring that the cutting operation can be completed quickly and smoothly when pressure is applied, avoiding material deformation or burr generation. The first frame 111 provides a stable support foundation for the entire cutting process, ensuring stability and safety during processing. Furthermore, the position of the cutting die 112 maintains a precise first positioning distance from the first positioning device 120, thereby ensuring the consistency of the cutting length each time and meeting the high requirements for dimensional accuracy in mass production.

[0029] Furthermore, according to the automatic keel cutting system of this utility model, the first positioning device 120 includes: a second frame 121, disposed on the first platform 100 and having a first positioning distance between it and the first frame 111; a positioning stop 122, movably disposed within the second frame 121 and located on the keel's conveying path; and a second drive cylinder 123, disposed on the second frame 121, with the positioning stop 122 mounted on the drive end of the second drive cylinder 123, for driving the positioning stop 122 closer to or further away from the keel's conveying path via the second drive cylinder 123. The first positioning device 120, through the second drive cylinder 123 driving the positioning stop 122 to change position within the second frame 121, achieves precise positioning and release of the keel after it has been conveyed to the correct position. When the keel is conveyed to the preset position by the conveying mechanism, the second drive cylinder 123 pushes the positioning stop 122 into the conveying path, abutting against the end of the keel to form a precise positioning reference, ensuring that the distance between it and the cutting mold 112 remains a constant first positioning distance. After the punching and cutting operations are completed, the positioning stop 122 is retracted by the second drive cylinder 123, disengaging from the keel conveying path to facilitate the feeding of the next keel. This structural design features fast response and accurate positioning, avoiding the errors caused by traditional manual visual inspection or mechanical limits. It not only improves production efficiency but also significantly enhances processing consistency and automation, making it suitable for continuous, high-speed automated keel production lines. Furthermore, the positioning stop 122 can be replaced or adjusted according to the end shape of different keel specifications.

[0030] Furthermore, according to the automatic keel cutting system of this utility model, a second positioning device 130 is also provided on the first platform 100, which is spaced a second positioning distance from the cutting device 110; the structure of the second positioning device 130 is the same as that of the first positioning device 120; the second positioning distance is twice the first positioning distance. Specifically, the second positioning device 130 provided on the first platform 100 maintains a second positioning distance (which is twice the first positioning distance) with the cutting device 110, which provides a variety of length options for keel processing. For example, when the first positioning distance is set to 600mm, the second positioning distance is 1200mm, which means that the system can flexibly switch between the production of two different standard lengths of keels on the same production line as needed, without readjusting the equipment or changing the molds.

[0031] The second positioning device 130 has the same structure as the first positioning device 120, including a positioning stop 122 movably disposed within the frame and a corresponding drive cylinder. This cylinder controls the positioning stop 122 to move closer to or further away from the keel conveying path, ensuring that the second positioning device 130 can also achieve precise positioning and guarantee the consistency of each cut length. Through simple programming or an interface selection, operators can choose to use either the first positioning device 120 or the second positioning device 130 for positioning, thus quickly adapting to different production task requirements.

[0032] It is understood that, based on this implementation, two or more positioning devices with different positioning distances can be set, or the positioning distance of the first positioning device 120 or the second positioning device 130 can be set to be adjustable. Specifically, by arranging multiple positioning devices with the same structure but different distances from the cutting device 110 sequentially along the keel conveying direction on the first platform 100, the system can support automatic processing of keels of more specifications and lengths, thereby meeting diverse engineering needs. In addition, if the positioning device is designed as an adjustable structure, for example, connected between the cutting device 110 and the first positioning device 120, and between the first positioning device 120 and the second positioning device 130 by a connecting screw and a nut limiting member, an adjustable positioning distance can be achieved. Specifically, on the keel conveying path of the first platform 100, the relative position between each positioning device and the cutting device 110 can be precisely adjusted by the connecting screw and nut limiting member set between them. The operator can rotate the screw to change the distance between the devices according to the required processing length, and lock it with the nut, thereby flexibly setting the first positioning distance and the second positioning distance. This structure not only retains the high efficiency of the original dual positioning system, but also further expands its scope of application, enabling the system to adapt to more non-standard sizes or customized production needs.

[0033] like Figure 3As shown, according to the present invention, an automatic keel cutting system includes a conveying mechanism comprising multiple conveying rollers 201 arranged along the length of a second platform 200. The conveying rollers 201 are evenly distributed on the support surface of the second platform 200, forming a continuous and stable keel conveying channel. The conveying rollers 201 can be driven synchronously by multiple motors or a motor-driven transmission mechanism to ensure stable and unbiased operation of the keel during conveying. To further improve conveying accuracy, some conveying rollers 201 can be equipped with limiting guide wheels or V-groove structures to prevent lateral sliding or deflection of the keel during movement, ensuring accurate arrival at the positioning device's workstation. Furthermore, the conveying mechanism can be linked with the control system to switch between intermittent and continuous feeding modes. For example, after completing one punching and cutting operation, the system controls the conveying rollers 201 to start, precisely delivering the keel to the next processing position, and then stops to wait for the next round of operations.

[0034] Furthermore, according to the automatic keel cutting system of this utility model, a servo drive device is provided at the bottom of the first platform 100, and a first slide rail 101 is provided above the first platform 100; the cutting device 110 and the first positioning device 120 are both slidably engaged with the first slide rail 101, and the servo drive device is used to drive the cutting device 110 and the first positioning device 120 to move synchronously along the first slide rail 101. The servo drive device provided at the bottom of the first platform 100 is connected to the cutting device 110 and the first positioning device 120 on the first slide rail 101 through a synchronous transmission mechanism, so that it can move smoothly as a whole along the first slide rail 101. This movement process is precisely controlled by the control system, and the position of the entire assembly on the first platform 100 can be adjusted according to different keel length specifications, thereby adapting to various processing requirements. The relative position between the cutting device 110 and the first positioning device 120 remains constant. By driving the entire assembly to move on the slide rail, their positional relationship relative to the conveying mechanism can be changed, realizing precise processing of keels of different standard lengths.

[0035] Furthermore, the automatic keel cutting system according to this utility model also includes a length compensation mechanism, comprising: a slide table 102 slidably mounted on a first slide rail 101 and connected to the drive end of a servo drive device; and a cylinder 103 mounted on the slide table 102, the cylinder 103 containing pre-stored buffer gas, and the cylinder rod of the cylinder 103 connected to the cutting device 110. When the cutting device 110 performs a cutting action, if it encounters additional resistance or slight material deformation, the buffer gas in the cylinder 103 can be compressed or released, allowing the cutting device 110 to slightly adjust its position, avoiding excessive pressure on the keel or incomplete cutting. This length compensation mechanism not only absorbs the changes in mechanical clearance caused by long-term use of the equipment, ensuring processing accuracy under long-term operation, but also meets the needs of high-hardness or thick-walled keels, ensuring that each cut is completed under optimal conditions. The length compensation mechanism adds greater flexibility and reliability to the automatic keel cutting system.

[0036] Furthermore, according to the automatic keel cutting system of this utility model, a second slide rail 202 is provided on the second platform 200, and the extension direction of the second slide rail 202 is the same as that of the first slide rail 101; the punching device 210 is slidably disposed on the second slide rail 202; a mold connecting rod 203 is provided between the punching device 210 and the cutting device 110 to enable the punching device 210 to slide synchronously with the cutting device 110. When adjusting the processing length, the punching device 210 and the cutting device 110 can move as a whole, keeping their relative positions unchanged, thereby ensuring the accuracy of each punching and cutting operation. The mold connecting rod 203 not only provides a mechanical connection, but also transmits motion between the two, so that while the servo drive device drives the cutting device 110 to move, it also drives the punching device 210 to slide synchronously along the second slide rail 202, simplifying the design of the control system and improving the stability and consistency of equipment operation.

[0037] Furthermore, according to the automatic keel cutting system of this utility model, a plurality of punching devices 210 are slidably arranged on the second slide rail 202; a secondary connecting rod 204 is provided between the plurality of punching devices 210 to maintain the spacing between the punching devices 210. By setting the secondary connecting rod 204 between the plurality of punching devices 210, it can be ensured that the preset spacing of each punching device 210 remains unchanged during the movement along the second slide rail 202, which is particularly important for keel processing that requires multi-point punching. The secondary connecting rod 204 not only maintains the fixed distance between the punching devices 210, but also provides additional stability during the movement, avoiding positional displacement caused by vibration or external force. The entire system, through precisely designed mechanical connections and control logic, realizes an efficient, precise and flexible keel processing flow, meeting the stringent requirements of modern building decoration engineering for product quality and production efficiency.

[0038] The keel automatic cutting system according to the preferred embodiment of this application integrates high-precision servo control and multi-station linkage technology in its process flow, realizing integrated automatic processing from raw material feeding to forming, punching, and cutting. The raw material first enters the main rolling mill system through an uncoiling device. After continuously forming the keel cross-section by passing through 20 sets of bending and pressing rollers, it enters the subsequent processing platform. The system includes two main functional platforms: the first platform 100 is equipped with a hydraulic cutting die 112, and the second platform 200 is equipped with a hydraulic figure-eight punching die. Both platforms are mounted on linear guide rails to ensure high-precision reciprocating motion, and are mechanically rigidly connected by linkages to maintain synchronous movement.

[0039] Furthermore, a synchronous tracking servo mechanism is incorporated into the system and installed below the first platform 100 to drive the cutting action. Due to the significant inertia of the keel during high-speed movement, a large-diameter cylindrical cylinder 103 is installed between the length control end of the mold on the first platform 100 and the fixed end of the servo screw to prevent positioning deviations and to buffer and counteract inertial forces. Once the cylinder 103 has completed buffering and stabilization, the servo system activates, precisely controlling the synchronous back-and-forth movement of the first platform 100 and the second platform 200 to achieve high-precision punching and cutting operations on the keel. The entire process requires no manual intervention, significantly improving production efficiency and product consistency, while also meeting the need for rapid switching between various keel specifications, thus enhancing the automation level and flexible manufacturing capabilities of the production line.

[0040] This utility model also provides a production line for ceiling keel products, which includes the automatic keel cutting system described in the above embodiments. This allows for digital synchronization of the forming and cutting processes, improving product accuracy and production efficiency, and reducing product delivery time. The production line for ceiling keel products provided by this utility model is described below, and the description of the production line can be used in conjunction with the automatic keel cutting system described above.

[0041] The production line for ceiling keel products achieves fully automated control and digital management from the front-end raw material uncoiling and continuous roll forming to the rear-end automatic punching and cutting. The production line sequentially includes an uncoiling device, a main roll forming system (including multiple sets of folding rolls), an automatic conveying mechanism, a punching device 210, and a cutting device 110, and integrates a servo synchronous tracking and shearing control system and a length compensation mechanism. After continuous forming, the keel profile is conveyed to the punching station via the conveying mechanism on the second platform 200. After positioning, it continues to be conveyed to the first platform 100, where it is precisely positioned by the first positioning device 120 or the second positioning device 130, and then the punching and cutting operations are performed synchronously.

[0042] Furthermore, the various functional modules in this production line are preferably linked through a PLC central control system to achieve integrated management of parameter setting, status monitoring, and fault diagnosis. Simultaneously, the system preferably supports rapid switching between multiple keel specifications. By adjusting the servo drive device to move the cutting device 110 and the punching device 210 along the slide rail, it adapts to the processing requirements of different length standards, significantly improving the equipment's flexible production capacity. This production line not only improves the dimensional accuracy and consistency of keel products but also integrates multiple discrete processes in the traditional production mode into continuous operation, increasing overall production efficiency by approximately 67%, significantly shortening product delivery cycles, and reducing labor costs and energy consumption, demonstrating promising prospects for widespread application.
