Description

Technical Field

[0001] This utility model belongs to the field of cutting technology, and specifically relates to a right-angle fully automatic cutting device. Background Technology

[0002] In the aluminum profile processing, door and window profile industry, and solar photovoltaic fields, cutting machines are widely used for processing aluminum profiles, plastic profiles, and other alloy profiles. In actual production, for already formed long strip profiles, it is usually necessary to first perform segmented cutting to facilitate product transportation and sales. Alternatively, for special requirements, the two ends may be finely cut in various ways. The precision of the segmented cutting process directly determines the accuracy of subsequent cutting processes and product quality.

[0003] Currently, most cutting machines on the market use a vertical up-and-down movement of the cutting blade to cut long strips of profiles. This method results in uneven force on the cutting blade during operation, leading to poor cutting stability and a tendency for cutting deviation, making it difficult to meet high-precision processing requirements. Furthermore, while some cutting machines exist with horizontally moving cutting blades, both vertical and horizontal models typically use cylinder-driven blades. Due to the unstable power output of cylinder drives, significant vibrations occur during operation, reducing cutting accuracy and affecting equipment stability. This results in larger dimensional errors in the cut profiles, lower yield rates, and difficulty in meeting the high-precision and high-efficiency requirements of modern industrial production.

[0004] Meanwhile, during the cutting process, a large amount of shavings are generated and fly everywhere, easily adhering to key components of the cutting machine such as the cylinder and guide rod. These adhering shavings increase the frictional resistance between components, hindering the normal extension and retraction of the cylinder and the smooth sliding of the guide rod, thereby further affecting the stability of the cutting movement, causing phenomena such as jamming and shaking during the cutting process, resulting in a significant decrease in cutting accuracy.

[0005] Furthermore, before cutting, long strips of material need to be clamped and secured to ensure stability during the cutting process. Existing equipment typically uses cylinders for clamping. However, most existing clamping cylinders are fixed structures, and their installation position cannot be adjusted according to actual needs. This means that when cutting materials of different widths and specifications, the clamping cylinder cannot adapt to the actual size of the material and cannot properly clamp it. This makes the material prone to displacement and shaking during the cutting process, affecting cutting accuracy, potentially causing safety hazards, and reducing production efficiency and product qualification rate.

[0006] Furthermore, current cutting machines require the material to stop before cutting can begin, making continuous cutting impossible. This is because existing conveying devices and cutting equipment lack effective coordination; the conveying device must pause during cutting, and the next segment of material can only be conveyed after the previous segment is completed. This cutting method results in significant waiting time throughout the production process, leading to a substantial decrease in cutting efficiency and making it difficult to meet the demands of large-scale industrial production. Therefore, improving the structural design of cutting machines, enhancing the precision and stability of segmented cutting processes, mitigating the adverse effects of cutting chips on equipment operation, and optimizing the structure of the pressure cylinder to accommodate different material specifications, thereby achieving continuous cutting and improving efficiency, have become pressing technical problems in this field. Summary of the Invention

[0007] The present invention aims to solve the existing technical problem by providing a right-angle fully automatic cutting device that can be matched with profile production equipment. As the profile is discharged, its cutting device can be synchronized with the discharge of the profile, thereby achieving continuous cutting, improving production efficiency while maintaining accuracy, and meeting actual production needs.

[0008] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0009] This utility model discloses a right-angle fully automatic cutting equipment, including a frame and a cutting device mounted on the frame. The cutting device achieves translation relative to the frame through a first translation mechanism, and the direction and speed of translation are consistent with the material discharge direction and discharge speed of the profile.

[0010] The cutting device includes a moving table and a cutting machine mounted on the moving table. The cutting machine moves relative to the moving table through a second translation mechanism, and the direction of movement of the cutting machine is perpendicular to the direction of movement of the cutting device. During the profile unloading process, this vertical movement of the cutting machine, combined with the horizontal movement of the cutting device and the profile in sync, can accurately cut a regular right-angle cut, ensuring cutting accuracy and meeting high-standard production requirements.

[0011] The cutting machine includes a cutting cover, a cutting blade installed inside the cutting cover, and a drive motor fixed to the cutting cover and connected to the cutting blade. A portion of the cutting blade is located in the cutting groove of the moving table.

[0012] The second translation mechanism is a belt conveyor device that drives the cutting cover to move. It includes a second servo motor, a drive wheel, a driven wheel, and a conveyor belt. The conveyor belt is wound between the drive wheel and the driven wheel. The drive wheel is driven by the second servo motor. The drive wheel and the driven wheel are respectively matched with chip blowing devices. The chip blowing devices blow off the chips generated during cutting that are stuck on the drive wheel and the driven wheel, preventing the drive wheel and the driven wheel from getting stuck.

[0013] The cutting cover is equipped with a material pressing device.

[0014] Compared to traditional drive methods, belt conveyors offer significant advantages, effectively improving the stability and efficiency of the moving platform, thereby enhancing cutting precision and efficiency. The conveyor belt is tightly wound between the drive and driven pulleys, forming a stable transmission circuit. When the second servo motor starts, it drives the drive pulley to rotate at a constant speed, smoothly transmitting power to the conveyor belt and driving the cutting cover to move smoothly along the predetermined direction. The working characteristics of the belt conveyor structure make the moving platform more stable during operation. On one hand, the belt itself has a certain degree of elasticity and flexibility, which can absorb and buffer some of the impact forces generated by motor starting, stopping, or load changes during transmission, reducing vibration and swaying of the moving platform. On the other hand, the contact area between the belt and the drive and driven pulleys is large, and the transmission process is smooth, avoiding problems such as tooth skipping and jamming that may occur with traditional chain drives, or excessive vibration that may occur with cylinder drives. This ensures that the moving speed of the cutting cover is uniform and stable, thus improving the overall stability of the moving platform.

[0015] During the cutting process, a large amount of fine and lightweight chips are generated, which are easily scattered and adhere to the belt, drive pulley, and driven pulley under the influence of the airflow generated during cutting and the vibration of the equipment. With prolonged operation, these chips gradually accumulate. On the one hand, the chips accumulating between the belt and the pulley grooves alter the contact state between the belt and the grooves, disrupting the originally stable frictional balance and causing belt slippage. This results in fluctuations in the moving speed of the cutting hood, preventing it from moving precisely along the predetermined trajectory and severely affecting cutting accuracy. On the other hand, chip accumulation on the bearings and rotating parts of the drive and driven pulleys increases frictional resistance between components, accelerates bearing wear, and may even cause bearing seizure, hindering the operation of the entire belt conveyor mechanism, causing equipment failure, significantly increasing maintenance costs and downtime, and severely impacting production progress. A chip blowing device continuously cleans the surface and surrounding area of ​​the drive and driven pulleys during equipment operation using high-pressure airflow or other effective methods. When the chips just splash onto the drive and driven wheels, the chip blowing device can blow them off in time, preventing them from accumulating. This effectively avoids problems such as belt slippage and component wear caused by chip accumulation, ensuring that the belt conveyor mechanism is always in a stable and efficient operating state, and ensuring that the cutting device can continuously and accurately complete the cutting task.

[0016] Before the cutting operation, the pressing device can press and fix the profile placed in the cutting hood. Because the pressing device is fixed relative to the moving table, and the moving table is consistent with the output direction and speed of the profile, it ensures that the profile will not shift or shake during the cutting process, providing a reliable guarantee for achieving high-precision right-angle cutting. At the same time, it reduces the safety risks caused by profile movement and improves the safety of equipment operation.

[0017] The cutting cover includes an upper cover and a lower cover. The upper cover is fixed on a moving platform, and the lower cover is fixed on a conveyor belt. A guide mechanism is provided between the lower cover and the moving platform.

[0018] The guiding mechanism includes two guide columns fixed on the moving platform and a guide block set on the guide columns, and the guide block is fixedly connected to the lower cover.

[0019] This split design allows for better integration of the cutting cover's movement with the belt conveyor structure. When the second translation mechanism moves the cutting cover, the guide columns and guide blocks work together to provide precise guidance for the lower cover's movement, limiting unnecessary offset or swaying during movement and ensuring the cutting cover moves smoothly along the predetermined vertical direction, further improving cutting accuracy and stability. Simultaneously, this structural design enhances the overall structural strength and rigidity of the cutting cover, making it less prone to deformation during frequent movements and extending its service life.

[0020] The bottom of the lower cover is provided with a discharge port, and a receiving tray is provided below the frame directly opposite the discharge port. The receiving tray is installed on the frame in the form of a drawer, and inclined guide plates are provided on both sides of the receiving tray.

[0021] The drawer-style receiving tray allows workers to easily remove and clean it when full, making operation convenient and quick. Furthermore, inclined guide plates are located on both sides of the tray; the angle of these guide plates is rationally designed to effectively collect and guide the chips generated during the cutting process.

[0022] The first translation mechanism is a lead screw conveying device, including a first servo motor, a lead screw, a lead screw seat, and a nut block. The nut block is fixed on the moving platform, and the lead screw is screwed into the nut block. One end of the lead screw is connected to the first servo motor, and the other end is matched on the lead screw seat. The moving platform is mounted on two guide rails via two linear bearings, and a dust cover is provided on the guide rails. The dust cover has a corrugated structure and a guide groove. The guide groove matches the guide rails, so that the dust cover remains connected to the guide rails when compressed or stretched, preventing dust from corroding the guide rails.

[0023] When the first servo motor drives the lead screw to rotate, the nut block converts the rotational motion into linear motion, driving the moving table to precisely translate along the lead screw axis. This lead screw transmission method has advantages such as high transmission accuracy, accurate positioning, and strong rigidity, ensuring that the translational speed of the moving table is precisely matched with the profile output speed, achieving synchronous movement between the cutting device and the profile, and effectively improving the stability and accuracy of continuous cutting. In addition, a small amount of chips will leak out during the cutting process. To prevent chips from corroding the guide rail, the dust cover in this design is always connected to the guide rail, effectively avoiding chip corrosion during cutting, ensuring smooth sliding of the linear bearing on the guide rail, extending the service life of the guide rail and linear bearing, and reducing equipment maintenance costs. The corrugated dust cover has good extensibility and flexibility, adapting to the frequent reciprocating motion of the moving table on the guide rail, and its smooth surface does not easily accumulate dust, further enhancing the dustproof effect.

[0024] The pressing device is installed on the long groove of the upper cover, directly opposite the feeding opening of the upper cover. The relative position of the pressing device to the feeding opening of the upper cover can be adjusted according to the feeding position. The pressing device includes a cylinder and a pressing block.

[0025] This adjustable design allows the clamping device to flexibly adapt to profiles of different widths and specifications. During actual cutting operations, operators can slide the clamping device left and right along the long groove according to the specific dimensions of the profile, ensuring that the clamping device is always positioned at the center line of the profile – the optimal position for effective clamping. Once the profile is conveyed to the upper cover's feed opening, the cylinder drives the clamping block downwards, firmly pressing the profile onto the moving table. This effectively prevents the profile from shifting or shaking during cutting, providing a reliable guarantee for high-precision right-angle cutting. Simultaneously, this clamping method reduces safety risks caused by profile movement, improves equipment operating safety, and further enhances production efficiency and product qualification rate.

[0026] The chip blowing device includes an air pipe and an air nozzle. The air pipe is connected to an air pump, and the air nozzle has a solenoid valve, which serves as a switch for whether the air nozzle sprays air or not.

[0027] This design enables precise airflow control of the chip blowing device. When the equipment is running, the solenoid valve opens or closes according to the control system's commands, thus controlling whether the air nozzles release air. During the cutting process, the solenoid valve opens in a timely manner, and the air nozzles spray high-pressure air to promptly blow away chips that splash onto the drive and driven wheels, preventing chip accumulation from affecting the normal operation of the belt conveyor. When the equipment stops running or chip blowing is not required, the solenoid valve closes, stopping the airflow and avoiding unnecessary energy consumption. This controllable chip blowing method ensures the stable operation of the belt conveyor and achieves rational energy utilization, further improving the equipment's reliability and economy.

[0028] This utility model also includes a film-coating device, which includes a width guiding mechanism and a height guiding mechanism. The width guiding mechanism includes a left guide wheel and a right guide wheel spaced apart from each other, and a left film winder and a right film winder are respectively provided at the positions of the left guide wheel and the right guide wheel. The height guiding mechanism includes two upper guide wheels and a lower guide wheel spaced apart from each other, and an upper film winder and a lower film winder are respectively provided at the positions of the upper guide wheel and the lower guide wheel. The distance between the left guide wheel and the right guide wheel can be adjusted left and right, and the distance between the upper guide wheel and the lower guide wheel can be adjusted up and down.

[0029] The moving platform is equipped with a guide device, which is set on the path of the profile moving towards the feed opening. The guide device includes a left guide plate and a right guide plate. The left guide plate and the right guide plate are movably fixed on the moving platform, so that the distance between them can be adjusted to accommodate profiles of different widths.

[0030] In summary, the beneficial effects of this utility model are:

[0031] Compared with existing technologies, the right-angle fully automatic cutting equipment of this invention effectively solves many problems existing in traditional cutting machines and has significant beneficial effects. In terms of cutting efficiency, the design of the cutting device and the profile output are synchronized, eliminating the drawback of the need to pause the profile feeding during traditional equipment cutting, realizing continuous cutting, greatly reducing the waiting time in the production process, and significantly improving production efficiency, which can fully meet the needs of large-scale industrial production.

[0032] In terms of cutting precision and stability, the first translation mechanism adopts a lead screw conveyor, and the second translation mechanism adopts a belt conveyor structure. Compared with the traditional drive method, the power output is more stable and the vibration of the equipment operation is reduced. The guide mechanism of the cutting cover ensures its precise movement and the cutting blade is subjected to balanced force, effectively avoiding problems such as cutting deviation and jamming, thereby ensuring cutting precision and improving product quality.

[0033] The reliability of equipment operation has also been enhanced. The dust cover on the guide rail, the chip blowing device on the drive and driven wheels, and the guide plate design of the receiving tray effectively prevent the erosion and impact of chips on the key components of the equipment, reduce component wear, lower the equipment failure rate, extend the service life of the equipment, and reduce maintenance costs.

[0034] Furthermore, the adjustable clamping device can adapt to profiles of different specifications, ensuring material stability during cutting, thus improving cutting accuracy and ensuring production safety. The coating device meets diverse production needs, further enhancing the equipment's practicality. Overall, through optimized structural design, this equipment achieves efficient, precise, and stable cutting operations, bringing significant technological advancements and economic benefits to the profile processing field.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0045] Please see Figures 1 to 9 This utility model provides a right-angle fully automatic cutting device, mainly composed of a frame 1 and a cutting device 2 mounted on the frame 1. Through the precise design and coordinated operation of each component, it achieves efficient and precise cutting operations. The specific implementation scheme is as follows:

[0046] The cutting device 2 is based on the first translation mechanism 3, which employs a lead screw conveyor design and includes key components such as the first servo motor 4, lead screw 5, lead screw seat 6, and nut block 7. The nut block 7 is securely fixed to the moving table 8. The lead screw 5 is threadedly connected to the nut block 7, with one end connected to the first servo motor 4 and the other end embedded in the lead screw seat 6. When the first servo motor 4 drives the lead screw 5 to rotate, the nut block 7 converts the rotational motion into linear motion, driving the moving table 8 to precisely translate along the axis of the lead screw 5. Thanks to the high precision, accurate positioning, and strong rigidity of the lead screw 5, the translation speed of the moving table 8 is precisely synchronized with the profile output speed, ensuring that the cutting device 2 and the profile conveying rhythm are consistent, achieving stable and high-precision continuous cutting. Meanwhile, the moving table 8 is mounted on two guide rails 10 with the help of two linear bearings 9. The guide rails 10 are equipped with a corrugated dust cover 11, whose guide groove 12 fits tightly with the guide rails 10. During the movement of the moving table, whether compressed or stretched, the dust cover 11 always remains connected to the guide rails 10, effectively preventing the cutting debris from eroding the guide rails, ensuring the smooth sliding of the linear bearings 9, extending the service life of the guide rails 10 and the linear bearings 9, reducing equipment maintenance costs, and its good extensibility and smooth surface further enhance the dustproof effect.

[0047] The cutting device 2 consists of a moving table 8 and a cutting machine 13. The cutting machine 13 moves relative to the moving table 8 via a second translation mechanism 14, and its direction of movement is perpendicular to the overall direction of movement of the cutting device 2. During the profile unloading process, the vertical movement of the cutting machine 13 and the horizontal movement of the cutting device 2 following the profile work together to accurately cut neat right-angle cuts, meeting high-standard production requirements. The second translation mechanism 14 uses a belt conveyor, consisting of a second servo motor 15, a drive wheel 16, a driven wheel 17, and a conveyor belt 18. The conveyor belt 18 forms a stable transmission circuit between the drive wheel 16 and the driven wheel 17. After the second servo motor 15 starts, it drives the drive wheel 16 to rotate at a constant speed, smoothly transmitting power to the conveyor belt 18, which in turn drives the cutting cover 19 to move smoothly in a predetermined direction. This conveyor belt can be a regular belt or a synchronous belt. Polyurethane is preferred as the material, with an integrally molded steel wire core, resulting in better overall corrosion resistance, wear resistance, and tensile strength. Compared to traditional drive methods, belt conveyors have significant advantages. The elasticity and flexibility of the belt itself can absorb the impact force generated by the motor starting, stopping, or load changes, reducing the vibration of the moving table. The larger contact area and stable transmission process avoid the problems of skipping teeth and jamming in chain drives and the large vibration of cylinder drives, ensuring that the moving speed of the cutting cover 19 is uniform and stable, effectively improving the stability and moving efficiency of the moving table 8, and thus improving the cutting accuracy and efficiency.

[0048] Inside the cutting machine 13, the cutting cover 19, the cutting blade 21, and the drive motor 22 work together to complete the cutting task. The cutting blade 21 is installed inside the cutting cover 19, with its central hole connected to the shaft of the drive motor 22, and the other part located in the cutting groove 23 of the moving table 8. The cutting cover 19 adopts a split design, consisting of an upper cover 24 and a lower cover 25. The upper cover 24 is fixed on the moving table 8 and moves synchronously with it, while the lower cover 25 is fixed on the conveyor belt. A guide mechanism is provided between the lower cover 25 and the moving table 8, consisting of two guide posts 26 fixed on the moving table 8 and a guide block 27 connected to the lower cover 25. When the second translation mechanism 14 moves the cutting cover 19, the guide posts 26 and the guide block 27 cooperate to provide precise guidance for the movement of the lower cover 25, limiting its offset and sway, ensuring that the cutting cover 19 moves smoothly in the vertical direction, enhancing the structural strength and rigidity of the cutting cover 19, extending its service life, and simultaneously allowing the movement of the cutting cover 19 to better integrate with the belt conveyor structure. The bottom of the lower cover 25 is equipped with a discharge port 28, through which the cutting debris is discharged. A drawer-type receiving tray 29 is provided under the frame 1, which is convenient for workers to pull out and clean when it is full. The inclined guide plates 30 on both sides of the receiving tray 29 are designed with a reasonable angle to collect the debris scattered during the cutting process, prevent the debris from accumulating around the equipment, maintain a clean working environment, and improve the orderliness of production and the stability of equipment operation.

[0049] Of course, the cut profiles are then gripped by external equipment (such as a robotic arm) and placed in a designated area.

[0050] To ensure the normal operation of the belt conveyor mechanism, the driving wheel 16 and driven wheel 17 are equipped with corresponding chip blowing devices. These devices consist of air pipes and air nozzles 31. One end of the air pipe is connected to the air nozzle 31, and the other end is connected to an air pump. An electromagnetic valve is installed at the air nozzle 31 to control the airflow. Of course, the electromagnetic valve can be set at any position on the chip blowing device, as long as it can control whether the air nozzle 31 sprays air. During equipment operation, the electromagnetic valve opens or closes according to the control system's instructions. During the cutting process, the air nozzle 31 is opened in a timely manner to spray high-pressure airflow, promptly blowing off the chips that splash onto the driving wheel 16 and driven wheel 17, preventing chip accumulation from affecting the belt conveyor. When the equipment stops or chip blowing is not required, the electromagnetic valve is closed to avoid energy waste, achieve precise airflow control, ensure the stable operation of the belt conveyor mechanism, and improve equipment reliability and economy.

[0051] Before the cutting operation, the pressing device plays a crucial role. It is screwed onto the elongated groove 32 of the upper cover 24, directly opposite the feed opening 33, and its position is adjustable. It consists of a cylinder 34 and a pressing block 35. The operator can slide and adjust the position of the pressing device along the elongated groove 32 according to the profile size, placing it in the optimal pressing position along the profile's centerline. When the profile is conveyed to the feed opening 33 of the upper cover 24, the cylinder 34 drives the pressing block 35 to move downwards, firmly pressing the profile onto the moving table 8. This prevents the profile from shifting or shaking during cutting, ensuring the accuracy of right-angle cutting, reducing safety risks, and improving production efficiency and product qualification rate. Synchronously, the first translation mechanism 3 and the second translation mechanism 14 work. The first translation mechanism 3 controls the moving table 8 to move along the moving direction of the profile and ensures synchronous movement. The second translation mechanism 14 pushes the cutting machine 13 to move vertically toward the profile, thereby completing the cutting of the profile. After the cutting is completed, the first translation mechanism 3 and the second translation mechanism 14 drive the corresponding moving table 8 and cutting machine 13 to reset.

[0052] The moving table 8 is equipped with a guiding device, which is positioned along the path of the profile moving towards the feed opening 33. The guiding device includes a left guide plate 48 and a right guide plate 49, which are movably fixed to the moving table 8, allowing adjustment of the distance between them to accommodate profiles of different widths. Specifically, the moving table 8 has several screw holes, and the left guide plate 48 and right guide plate 49 each have several elongated holes 50. Bolts pass through the elongated holes 50 and are screwed into them. By loosening the bolts, the left-right position of the elongated holes 50 relative to the bolts is adjusted, thereby adjusting the distance.

[0053] In addition, this equipment is also equipped with a film coating device 36, which is placed before the right-angle fully automatic cutting equipment of this utility model. This device can coat and protect the surface of the profile 37 before cutting, meeting diverse production needs and further improving the practicality and applicability of the equipment. The film coating device includes a width guiding mechanism 38 and a height guiding mechanism 39. The width guiding mechanism 38 includes a left guide wheel 40 and a right guide wheel 41 spaced apart, with a left film winder 42 and a right film winder 43 corresponding to the positions of the left and right guide wheels 40 and 41, respectively. The height guiding mechanism 39 includes two upper guide wheels 44 and a lower guide wheel 45 spaced apart vertically, with an upper film winder 46 and a lower film winder 47 corresponding to the positions of the upper and lower guide wheels 44 and 45, respectively. To adapt to different specifications of profiles, the left guide wheel 40 and the right guide wheel 41 can be adjusted horizontally, and the upper guide wheel 44 and the lower guide wheel 45 can be adjusted vertically. During use, the operator pre-adjusts the spacing of each guide roller according to the actual width and height of the profile 37. Then, the left film winder 42, right film winder 43, upper film winder 46, and lower film winder 47 work together to guide the protective film through the guide rollers and accurately cover the surface of the profile 37. Before cutting, it can protect the profile 37 and avoid surface damage; after cutting, it can protect the finished product and prevent scratches, wear and other problems during transportation and storage.

[0054] The above provides a detailed description of the right-angle fully automatic cutting equipment provided in the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the technical solutions disclosed in this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
