Description

Technical Field

[0001] This invention relates to the technical field of the packaging industry, specifically to a vertical direct-pressure groove shoulder device and its operating method. Background Technology

[0002] In the aluminum can processing of the packaging industry, the grooved shoulder machine is a key piece of equipment used to groove and press aluminum cans to ensure their structural stability, sealing performance, and aesthetic appearance. A traditional grooved shoulder machine typically consists of a base, a central support point, three pressure rollers, and an angled cone. Its working principle is based on the coordinated movement of the cone and bearings, with the central support point enabling the three sets of pressure rollers to simultaneously press the aluminum can. Specifically, the pressure rollers are connected to the base via a rotating shaft and move along a specific trajectory guided by the cone, thereby forming grooves on the outer wall of the aluminum can. However, this design has significant technical shortcomings in practical applications, making it difficult to meet the high-precision machining requirements of modern industry.

[0003] First, the pressure rollers of traditional grooved shoulder presses inevitably exhibit an arc-shaped motion trajectory during the pressing process. Because the contact point between the pressure roller and the outer wall of the aluminum can changes continuously with the rotation of the cone, the direction of the force exerted by the pressure roller on the aluminum can shifts periodically. This instability in force direction easily leads to deviations in groove depth, width, and curvature. Especially under high-speed production or complex process conditions, dimensional errors may be further amplified, ultimately resulting in decreased compatibility between the aluminum can and its matching container, and even affecting sealing performance. Second, traditional structures rely on the mechanical fit between the cone and bearings. Their motion accuracy is highly dependent on the machining accuracy and assembly tolerances of the components. After long-term operation, wear can easily lead to distortion of the motion trajectory, further exacerbating fluctuations in processing quality. Furthermore, existing technology has poor adaptability to various aluminum can sizes. The installation position, tilt angle, and pressing force of the pressure roller are difficult to adjust quickly, requiring frequent component replacement or manual intervention, increasing equipment maintenance costs and production preparation time.

[0004] More importantly, traditional grooved shoulder presses lack real-time monitoring and dynamic adjustment capabilities for the processing, and cannot adaptively adjust according to the aluminum can material, thickness, or groove design requirements. For example, when pressing high-strength aluminum, the pressure roller may undergo plastic deformation due to excessive force, or the groove may be incompletely formed due to insufficient pressure. At the same time, the frictional heat generated by the arc motion can accelerate the wear of the pressure roller and reduce the service life of the equipment. Summary of the Invention

[0005] To address the significant shortcomings of existing technologies mentioned in the background section regarding pressing accuracy, adaptability, and intelligence, this invention provides a vertical direct-pressure groove shoulder machine and its operating method. By utilizing the cooperation of ball bearings and rails, vertical linear pressing by the rollers is achieved, ensuring precise groove placement. It features multi-specification adaptability, intelligent control, and multi-functional modules, forming a novel groove shoulder machine that provides linear vertical pressing, stable force direction, and compatibility with various aluminum can sizes, thereby improving processing efficiency and product quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: One objective of this invention is to provide a vertical direct-pressure groove shoulder, comprising: The base 1 has a central support point 3 at the top; The rotary drive assembly includes a motor, a belt, and a large pulley 2. The motor drives the large pulley 2 to rotate via the belt. The large pulley 2 is fixedly connected to the rotating cylinder 4 and drives it to rotate around the central axis of the base 1. The roller adjustment assembly includes three rollers 9 evenly distributed in a circle, a roller seat 7 and a rotating shaft (6). The rollers 9 are evenly distributed in a circle outside the middle support point 3 and are hinged to the roller seat 7. The roller assembly includes an outer roller 10 and a conformal track 5. The outer roller 10 is sleeved on the outside of the rotating cylinder 4 and rotates synchronously. The conformal track 5 is disposed on the inner wall of the outer roller 10. The end of the roller seat 7 is provided with a single ball and rolls in contact with the conformal track 5. The conformal track 5 includes a guide section, a pressing section and a reset section. The radial dimension of the guide section gradually decreases along the rotation direction. The pressing section has a constant diameter structure. The radial dimension of the reset section gradually increases along the rotation direction. The rotating shaft 6 is fixed coaxially with the outer roller 10, and the roller seat 7 is slidably connected to the outer roller 10. The sliding connection between the roller seat 7 and the base 1 is provided with a guide structure distributed radially along the aluminum can. The surface of the roller 9 is hardened and the edge is provided with an arc-shaped pressing surface that matches the curvature of the groove in the aluminum can.

[0007] As a further improvement to the vertical direct-pressure groove shoulder, the positioning boss of the intermediate support point 3 is an adjustable structure, including a manually adjustable bolt or a telescopic mechanism driven by a servo motor.

[0008] As a further improvement to the vertical direct-pressure groove shoulder, the rotating shaft 6 has an adjustable angle structure, and the tilt angle of the roller 9 can be adjusted by manually adjusting the handle or by driving the servo motor.

[0009] As a further improvement to the vertical direct-pressure shoulder tool, the roller adjustment assembly also includes a shoulder-gathering roller 8, which is rotatably connected to the roller seat 7 via a pin and is used to assist in forming the shoulder of the aluminum can.

[0010] As a further improvement to the vertical direct-pressure groove shoulder, the sliding connection between the roller seat 7 and the base 1 is provided with a sliding groove, and the inner wall of the sliding groove is provided with a nickel plating layer to reduce frictional resistance.

[0011] As a further improvement to the vertical direct-pressure groove shoulder, the guide section and the pressing section of the conformal track 5 are connected by a transition section, and the radial dimension of the transition section gradually changes to smooth the movement state of the roller seat 7.

[0012] The second objective of this invention is to provide an operating method for a vertical direct-pressure groove shoulder, comprising the following steps: Install the shoulder piece onto the production equipment fixing device and confirm that the base 1 is connected to the equipment interface; Place the aluminum can to be processed at the middle support point 3, and make the positioning boss match the inner hole at the bottom of the aluminum can; Start the motor, and drive the large pulley 2 via belt to drive the rotating drum 4 and the outer roller 10 to rotate synchronously. The grinding disc moves closer to the fixed turntable, the aluminum can moves with the grinding disc and comes into contact with the groove shoulder support ring, and the roller seat 7 separates from the outer wall of the aluminum can under the action of centrifugal force. The guide section of the conformal track 5 on the inner wall of the outer roller 10 pushes the roller seat 7 to move perpendicularly towards the aluminum can along the sliding direction of the base 1, and the roller 9 gradually approaches the outer wall of the aluminum can. When the ball enters the pressing section of the conformal track 5, the roller seat 7 stops moving, and the roller 9 presses the groove with constant pressure in a direction perpendicular to the outer wall of the aluminum can. After the ball enters the reset section, the roller seat 7 resets, the roller 9 disengages from the aluminum can, the mold disc separates in the opposite direction, and the aluminum can moves out of the pressing area.

[0013] As a further improvement to the operating method, it also includes a pressure sensor that monitors the pressing force of the roller 9 in real time and dynamically adjusts the movement trajectory of the roller seat 7 through a central processing unit.

[0014] As a further improvement to the operating method, a multi-station switching device is also included, which realizes automatic switching between different stations through a rotary table and positioning pins, adapting to the processing of aluminum cans of various specifications.

[0015] As a further improvement to the operating method, a multi-functional processing head switching step is also included, which achieves groove repair or polishing by changing roller 9, shoulder roller 8 and auxiliary tools.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This technology achieves vertical linear pressing of the rollers through the cooperation of conformal tracks and balls, completely eliminating the force offset caused by traditional arc motion, ensuring precise and stable groove dimensions, and significantly improving processing accuracy and product consistency.

[0017] It supports compatibility with multiple aluminum can sizes, and the positions of the central support point and rollers are adjustable. Combined with intelligent control and multi-functional modules, it effectively solves the problem of insufficient adaptability of traditional equipment to different sizes and processes, and improves the equipment's versatility and production efficiency.

[0018] Integrating pressure / position sensors and dynamic adjustment functions enables real-time monitoring and adaptive adjustment of the processing, reducing manual intervention and enhancing the automation level of the equipment; at the same time, the roller quenching treatment and guide structure design extend the service life, taking into account both high precision and high reliability.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Vertical direct-pressure groove shoulder device based on conformal track guidance.

[0023] This embodiment provides a vertical direct-pressure groove shoulder press based on a conformal track. The conformal track on the inner wall of the outer roller engages with the ball bearings at the end of the roller seat, ensuring that the roller maintains a linear feed motion perpendicular to the outer wall of the aluminum can throughout the pressing process. This solution uses a motor-driven belt to rotate a large pulley, which in turn drives the rotating cylinder and the outer roller to rotate synchronously. Simultaneously, the contour change of the conformal track guides the sliding of the roller seat, enabling the roller to achieve precise linear pressing during the groove pressing process on the aluminum can.

[0024] Please see Figures 1-3 A vertical direct-pressure groove shoulder device includes a base 1, a rotary drive assembly, a roller adjustment assembly, and a roller mating assembly.

[0025] The base 1 has a central support point 3 at its top. The rotary drive assembly includes a motor, a belt, and a large pulley 2. The motor drives the large pulley 2 to rotate via the belt. The large pulley 2 is fixedly connected to the rotating cylinder 4 and drives it to rotate around the central axis of the base 1. The roller adjustment assembly includes three rollers 9, a roller seat 7, and a rotating shaft 6. The three rollers 9 are evenly distributed in a circle on the outside of the central support point 3 and are hinged to the roller seat 7. The roller mating assembly includes an outer roller 10, a single ball bearing, and a conformal track 5. The outer roller 10 is fitted on the outside of the rotating cylinder 4 and rotates synchronously. The conformal track 5 is located on the inner wall of the outer roller 10. The single ball bearing is embedded in the end of the roller seat 7 and rolls in contact with the conformal track 5. The contour of the conformal track 5 guides the roller seat 7 to drive the roller 9 to make a linear feed motion perpendicular to the outer wall of the aluminum can. The rotating shaft 6 is fixed coaxially with the outer roller 10, and the roller seat 7 is slidably connected to the outer roller 10.

[0026] In this embodiment, by starting the motor, the motor transmits power to the large pulley 2 through the belt. The large pulley 2 is fixedly connected to the rotating cylinder 4, thus driving the rotating cylinder 4 to rotate around the central axis of the base 1. At the same time, the outer roller 10 sleeved on the outside of the rotating cylinder 4 moves in a circular motion synchronously with the rotating cylinder 4, providing basic power for the subsequent pressing action. Then, the aluminum can to be processed is placed at the middle support point 3 on the top of the base 1, and the middle support point 3 provides stable support for the aluminum can. At this time, the mold disc and the fixed turntable are not in contact. The roller seat 7, roller 9 and shoulder roller 8 are separated from the outer wall of the aluminum can under the action of centrifugal force, ensuring that the aluminum can is fed smoothly and is not affected by the initial external force. When the mold disc moves relative to the fixed turntable, the aluminum can moves with the mold disc and gradually contacts the support ring of the shoulder device, triggering the pressing preparation action. The conforming track 5 on the inner wall of the outer roller 10 rotates with the roller. The radial dimension of its guide section gradually decreases along the rotation direction and contacts the single ball at the end of the roller seat 7. The ball is pushed by the contour change of the conforming track 5, which in turn drives the roller seat 7 to move towards the aluminum can perpendicular to the central axis of the aluminum can along the sliding direction of the base 1. At the same time, the roller 9 moves synchronously with the roller seat 7 and gradually approaches the outer wall of the aluminum can. The shoulder roller 8 also moves towards the shoulder of the aluminum can with the roller seat 7. When the single ball enters the equal diameter structure of the pressing section of the conforming track 5, the roller seat 7 stops moving towards the aluminum can and maintains a stable position. At this time, under the constraint of the rotating shaft 6, the roller 9 presses the aluminum can in a direction perpendicular to the outer wall of the aluminum can. Since the three rollers 9 are evenly distributed in a circle and projected as an equilateral triangle, with the center coinciding with the central axis of the middle support point 3, the pressing force is evenly applied to the surface of the aluminum can, avoiding the force offset caused by the arc motion in the traditional technology, and ensuring that the groove is formed according to the preset size. At the same time, the shoulder roller 8 moves synchronously with the roller seat 7, and cooperates with the roller 9 to assist in the forming of the shoulder of the aluminum can, ensuring the connection accuracy between the shoulder of the aluminum can and the groove.

[0027] Additional explanation: The contour of the conformal track 5 is stepped. The conformal track 5 includes a guide section, a pressing section, and a reset section. The radial dimension of the guide section gradually decreases along the rotation direction, pushing the roller seat 7 to move the roller 9 closer to the aluminum can. The pressing section has a constant diameter structure, which allows the roller 9 to maintain constant pressure and press the aluminum can vertically. The radial dimension of the reset section gradually increases along the rotation direction, which allows the roller 9 to detach from the surface of the aluminum can. The surface of the roller 9 is hardened, and the edge surface of the roller 9 has an arc-shaped pressing surface with the same curvature as the groove design of the aluminum can. The sliding connection between the roller seat 7 and the base 1 has a guide structure distributed radially along the aluminum can. The guide structure restricts the roller seat 7 to only make linear movements perpendicular to the central axis of the aluminum can, avoiding radial movement during the pressing of the roller 9. The sliding connection between the offset roller seat 7 and the base 1 is provided with a guide structure distributed radially along the aluminum can. The guide structure restricts the roller seat 7 to only make linear movements perpendicular to the central axis of the aluminum can, so as to avoid radial offset when the roller 9 is pressing. The surface of the rotating cylinder 4 is nickel-plated, and its inner wall is provided with a sliding groove that cooperates with the roller seat 7. Both ends are rotatably connected to the base 1 through bearings, and the acute angles are blunted. The roller adjustment assembly also includes a shoulder roller 8, which is rotatably connected to the roller seat 7 through a pin. The top of the intermediate support point 3 is provided with a positioning boss. The diameter of the positioning boss is adapted to the inner hole of the bottom of the aluminum can and is used for axial positioning when pressing the aluminum can. The three rollers 9 are distributed in an equilateral triangle, and their center coincides with the central axis of the intermediate support point 3 to ensure uniform distribution of pressing force. As the radial dimension of a single ball enters the reset section of the conformal track 5 and gradually increases along the rotation direction, the contour change of the conformal track 5 causes the ball to move away from the aluminum can. The roller seat 7 resets synchronously with the ball, which in turn causes the roller 9 and the shoulder roller 8 to detach from the surface of the aluminum can. At this time, the mold disk separates from the fixed turntable in the opposite direction, and the aluminum can moves out of the pressing area with the mold disk, completing one groove pressing process.

[0028] The specific operating steps are as follows: Install the shoulder piece onto the fixing device of the production equipment, ensuring that the base 1 is securely connected to the installation interface of the equipment. Check whether the motor, belt, and large pulley 2 of the rotary drive assembly are operating normally, and ensure that the rotating drum 4 can rotate stably.

[0029] The aluminum can to be processed is placed at the middle support point 3 on the top of the base 1. The positioning boss of the middle support point 3 is adapted to the inner hole at the bottom of the aluminum can to ensure that the aluminum can maintain axial stability during the pressing process.

[0030] The motor is started, and power is transmitted to the large pulley 2 via a belt, driving the rotating drum 4 to rotate around the central axis of the base 1. The outer roller 10 rotates synchronously with the rotating drum 4, providing basic power for subsequent pressing operations.

[0031] As the grinding disc moves relative to the fixed turntable, the aluminum can moves with the grinding disc and gradually comes into contact with the support ring of the groove shoulder. At this time, the roller seat 7 remains separated from the outer wall of the aluminum can under the action of centrifugal force, ensuring that the aluminum can is fed smoothly and is not affected by the initial external force.

[0032] As the mold disc and the fixed turntable approach each other, the conformal track 5 on the inner wall of the outer roller 10 begins to act on the roller seat 7. Individual balls contact the guide section of the conformal track 5, pushing the roller seat 7 towards the aluminum can along the sliding direction of the base 1, perpendicular to the central axis of the aluminum can. The roller 9 moves synchronously with the roller seat 7, gradually approaching the outer wall of the aluminum can and beginning to press the aluminum can.

[0033] When a single ball enters the pressing section of the conformal track 5, the roller seat 7 stops moving towards the aluminum can and maintains a stable position. At this time, under the constraint of the rotating shaft 6, the roller 9 applies constant pressure to the aluminum can in a direction perpendicular to the outer wall of the aluminum can. Since the three rollers 9 are evenly distributed circumferentially, the pressing force is applied evenly to the surface of the aluminum can, avoiding the force displacement caused by the arc motion in traditional technology.

[0034] When a single ball enters the reset section of the conformal track 5, the contour change of the conformal track 5 causes the ball to move away from the aluminum can. The roller seat 7 resets synchronously with the ball, which in turn causes the roller 9 and the shoulder roller 8 to detach from the surface of the aluminum can. At this time, the mold disc separates from the fixed turntable in the opposite direction, and the aluminum can moves out of the pressing area with the mold disc, completing one groove pressing process.

[0035] After each pressing cycle, inspect the surface wear of roller 9 and replace or repair it if necessary. Simultaneously, inspect the wear of the conformal track 5 to ensure the accuracy of its contour changes. Regularly lubricate and clean the rotary drive assembly to extend the equipment's lifespan.

[0036] This embodiment achieves efficient and stable pressing of aluminum can grooves through precise structural design and motion control. The vertical direct pressing motion of roller 9 avoids the force displacement caused by the arc motion in traditional technologies, ensuring that the groove dimensions meet design requirements. The stepped design of the conformal track 5 allows roller 9 to maintain constant pressure during pressing, improving the accuracy of groove processing. The quenching treatment and arc pressing surface design of roller 9 enhance its wear resistance and processing effect, extending the service life of the equipment. In addition, the guiding structure of roller seat 7 effectively limits radial displacement, further improving the stability of pressing.

[0037] Example 2: Vertical direct pressure groove shoulder fitting for multi-specification aluminum cans.

[0038] This embodiment provides a specific implementation of a multi-specification aluminum can adaptable vertical direct-pressure groove shoulder tool, aiming to achieve efficient processing of aluminum cans of different specifications through modular design and adjustable structure. Based on the basic groove shoulder tool, this tool adds an adjustable intermediate support point 3 and a positioning device with rollers 9 to adapt to the processing needs of aluminum cans of different sizes.

[0039] The diameter of the intermediate support point 3 is designed to be adjustable. A retractable positioning boss allows it to adapt to the bottom inner hole of aluminum cans of different sizes. The positioning boss can be adjusted manually or automatically. Manual adjustment is achieved by rotating the adjusting bolt, while automatic adjustment is achieved by a servo motor driving the extension and retraction of the positioning boss to automate the process.

[0040] The roller adjustment assembly incorporates an adjustable positioning device, allowing the installation position of roller 9 to be adjusted according to the size of the aluminum can. The positioning device includes a sliding guide rail and a positioning pin. The sliding guide rail is located at the bottom of the roller seat 7, and the positioning pin is fixed to the sliding guide rail via a threaded connection to limit the movement range of roller 9. By adjusting the position of the positioning pin, the contact point between roller 9 and the outer wall of the aluminum can can be changed, adapting to the processing requirements of aluminum cans of different sizes.

[0041] The rotating shaft 6 of the roller adjustment assembly features an adjustable angle design, allowing the tilt angle of the roller 9 to be adjusted according to the groove design of the aluminum can. The rotating shaft 6 can be adjusted manually or automatically. Manual adjustment is achieved by rotating the adjustment handle, while automatic adjustment uses a servo motor to drive the rotation of the rotating shaft 6 for precise angle control.

[0042] The specific operating steps include: Install the shoulder piece onto the fixing device of the production equipment, ensuring that the base 1 is securely connected to the installation interface of the equipment. Check whether the motor, belt, and large pulley 2 of the rotary drive assembly are operating normally, and ensure that the rotating drum 4 can rotate stably.

[0043] According to the specifications of the aluminum can, adjust the diameter of the positioning boss at the intermediate support point 3 to match the inner hole at the bottom of the aluminum can. At the same time, adjust the positioning device of the roller adjustment assembly to ensure that the installation position of the roller 9 matches the contact point with the outer wall of the aluminum can.

[0044] The motor is started, and power is transmitted to the large pulley 2 via a belt, driving the rotating drum 4 to rotate around the central axis of the base 1. The outer roller 10 rotates synchronously with the rotating drum 4, providing basic power for subsequent pressing operations.

[0045] As the grinding disc moves relative to the fixed turntable, the aluminum can moves with the grinding disc and gradually comes into contact with the support ring of the groove shoulder. At this time, the roller seat 7 remains separated from the outer wall of the aluminum can under the action of centrifugal force, ensuring that the aluminum can is fed smoothly and is not affected by the initial external force.

[0046] As the mold disc and the fixed turntable approach each other, the conformal track 5 on the inner wall of the outer roller 10 begins to act on the roller seat 7. Individual balls contact the guide section of the conformal track 5, pushing the roller seat 7 towards the aluminum can along the sliding direction of the base 1, perpendicular to the central axis of the aluminum can. The roller 9 moves synchronously with the roller seat 7, gradually approaching the outer wall of the aluminum can and beginning to press the aluminum can.

[0047] When a single ball enters the pressing section of the conformal track 5, the roller seat 7 stops moving towards the aluminum can and maintains a stable position. At this time, under the constraint of the rotating shaft 6, the roller 9 applies constant pressure to the aluminum can in a direction perpendicular to the outer wall of the aluminum can. Since the three rollers 9 are evenly distributed circumferentially, the pressing force is applied evenly to the surface of the aluminum can, avoiding the force displacement caused by the arc motion in traditional technology.

[0048] When a single ball enters the reset section of the conformal track 5, the contour change of the conformal track 5 causes the ball to move away from the aluminum can. The roller seat 7 resets synchronously with the ball, which in turn causes the roller 9 and the shoulder roller 8 to detach from the surface of the aluminum can. At this time, the mold disc separates from the fixed turntable in the opposite direction, and the aluminum can moves out of the pressing area with the mold disc, completing one groove pressing process.

[0049] After each pressing cycle, inspect the surface wear of roller 9 and replace or repair it if necessary. Simultaneously, inspect the wear of the conformal track 5 to ensure the accuracy of its contour changes. Regularly lubricate and clean the rotary drive assembly to extend the equipment's lifespan.

[0050] This embodiment achieves efficient processing of aluminum cans of different specifications through modular design and adjustable structure. The adjustable intermediate support point 3 and the positioning device of the roller 9 enable the shoulder cutter to adapt to the processing needs of aluminum cans of various sizes, improving the versatility and flexibility of the equipment. The adjustable angle design of the roller adjustment assembly further enhances the shoulder cutter's adaptability to different groove designs, ensuring the accuracy and consistency of groove processing. Furthermore, the guiding structure of the roller seat 7 effectively limits radial offset, improving the stability of pressing.

[0051] Example 3: Intelligent control type vertical direct pressure groove shoulder.

[0052] This embodiment provides a specific implementation of an intelligent control type vertical direct pressure groove shoulder tool, aiming to achieve real-time monitoring and automatic adjustment of the aluminum can groove processing process by introducing sensors and a control system. Based on the basic groove shoulder tool, this tool adds pressure sensors, position sensors, and an intelligent control system to improve processing accuracy and the level of equipment intelligence.

[0053] The intelligent control system includes a central processing unit, a sensor module, and an actuator. The central processing unit receives data from the sensor module and controls the action of the actuator according to preset processing parameters. The sensor module includes a pressure sensor and a position sensor, used to monitor the pressing force of the roller 9 and the moving position of the roller seat 7, respectively.

[0054] A pressure sensor is integrated into the bottom of roller 9 to monitor the pressing force of roller 9 on the aluminum can in real time. The data from the pressure sensor is transmitted to the central processing unit via a wireless transmission module. The central processing unit adjusts the pressing action of roller 9 according to a preset pressing force threshold to ensure that the pressing force remains constant.

[0055] A position sensor is integrated into the sliding connection of the roller holder 7 to monitor the movement position of the roller holder 7 in real time. The data from the position sensor is transmitted to the central processing unit via a wireless transmission module. The central processing unit adjusts the movement trajectory of the roller holder 7 according to the preset movement distance to ensure that the pressing process of the roller 9 proceeds smoothly.

[0056] The specific operating steps include: Install the shoulder piece onto the fixing device of the production equipment, ensuring a secure connection between the base 1 and the equipment's mounting interface. Check that the motor, belt, and large pulley 2 of the rotary drive assembly are operating normally, ensuring that the rotating drum 4 can rotate stably. Simultaneously, check that the sensor module and central processing unit of the intelligent control system are functioning correctly.

[0057] The aluminum can to be processed is placed at the middle support point 3 on the top of the base 1. The positioning boss of the middle support point 3 is adapted to the inner hole at the bottom of the aluminum can to ensure that the aluminum can maintain axial stability during the pressing process.

[0058] The motor is started, and power is transmitted to the large pulley 2 via a belt, driving the rotating drum 4 to rotate around the central axis of the base 1. The outer roller 10 rotates synchronously with the rotating drum 4, providing basic power for subsequent pressing operations.

[0059] As the grinding disc moves relative to the fixed turntable, the aluminum can moves with the grinding disc and gradually comes into contact with the support ring of the groove shoulder. At this time, the roller seat 7 remains separated from the outer wall of the aluminum can under the action of centrifugal force, ensuring that the aluminum can is fed smoothly and is not affected by the initial external force.

[0060] As the mold disc and the fixed turntable approach each other, the conformal track 5 on the inner wall of the outer roller 10 begins to act on the roller seat 7. Individual balls contact the guide section of the conformal track 5, pushing the roller seat 7 towards the aluminum can along the sliding direction of the base 1, perpendicular to the central axis of the aluminum can. The roller 9 moves synchronously with the roller seat 7, gradually approaching the outer wall of the aluminum can and beginning to press the aluminum can.

[0061] During the pressing process, the pressure sensor monitors the pressing force of the roller 9 in real time and transmits the data to the central processing unit (CPU). The CPU adjusts the pressing action of the roller 9 according to a preset pressing force threshold to ensure that the pressing force remains constant. Simultaneously, the position sensor monitors the movement position of the roller seat 7 in real time and transmits the data to the CPU. The CPU adjusts the movement trajectory of the roller seat 7 according to a preset movement distance to ensure that the pressing process of the roller 9 proceeds smoothly.

[0062] When a single ball enters the reset section of the conformal track 5, the contour change of the conformal track 5 causes the ball to move away from the aluminum can. The roller seat 7 resets synchronously with the ball, which in turn causes the roller 9 and the shoulder roller 8 to detach from the surface of the aluminum can. At this time, the mold disc separates from the fixed turntable in the opposite direction, and the aluminum can moves out of the pressing area with the mold disc, completing one groove pressing process.

[0063] After each pressing cycle, check the operating status of the pressure and position sensors to ensure the accuracy of their data acquisition. Simultaneously, check the central processing unit and actuators of the intelligent control system to ensure they are functioning properly, performing maintenance and calibration as necessary.

[0064] This embodiment introduces an intelligent control system to achieve real-time monitoring and automatic adjustment of the aluminum can grooving process. The integrated design of pressure and position sensors allows the grooving shoulder to dynamically adjust the pressing force and movement trajectory according to the actual processing conditions, ensuring the accuracy and consistency of the grooving process. The introduction of the intelligent control system improves the automation level of the equipment, reduces manual intervention, and increases production efficiency and equipment reliability. Furthermore, the intelligent control type grooving shoulder is suitable for complex processes and high-precision processing scenarios, meeting the higher requirements of the modern packaging industry for product quality and production efficiency.

[0065] Example 4: Multifunctional vertical direct pressure groove shoulder.

[0066] This embodiment provides a specific implementation of a multifunctional vertical direct-pressure groove shoulder tool, aiming to meet diverse needs for grooving aluminum cans by integrating multiple functional modules. Based on the basic groove shoulder tool, this tool adds a multi-axis adjustment mechanism, a multi-station switching device, and a multifunctional processing head to improve the flexibility and applicability of the equipment.

[0067] The multi-axis adjustment mechanism includes a rotating shaft 6 and a sliding guide rail, allowing the roller 9 to be adjusted in multiple directions. The rotating shaft 6 is driven by a high-precision servo motor to achieve precise angle adjustment of the roller 9. The sliding guide rail is located at the bottom of the roller seat 7, allowing the roller 9 to be finely adjusted radially and axially to accommodate groove designs of different shapes.

[0068] The multi-station switching device includes a rotary table and locating pins, allowing the shoulder piece to switch between different stations. The rotary table is located on top of the base 1 and is driven to rotate by a servo motor to achieve automatic station switching. The locating pins are fixed to the rotary table by threaded connections to ensure the accuracy of station switching.

[0069] The multi-functional processing head includes rollers 9, shoulder-retracting rollers 8, and auxiliary tools, which can be replaced according to processing needs. Rollers 9 and shoulder-retracting rollers 8 feature a modular design for easy and quick replacement and maintenance. Auxiliary tools include scrapers and polishing wheels for subsequent treatment of the grooves, improving processing quality.

[0070] The specific operating steps include: Install the shoulder piece onto the mounting device of the production equipment, ensuring a secure connection between the base 1 and the equipment's mounting interface. Check the operating status of the multi-axis adjustment mechanism, multi-station switching device, and multi-functional processing head to ensure that each functional module is working properly.

[0071] The aluminum can to be processed is placed at the middle support point 3 on the top of the base 1. The positioning boss of the middle support point 3 is adapted to the inner hole at the bottom of the aluminum can to ensure that the aluminum can maintain axial stability during the pressing process.

[0072] The motor is started, and power is transmitted to the large pulley 2 via a belt, driving the rotating drum 4 to rotate around the central axis of the base 1. The outer roller 10 rotates synchronously with the rotating drum 4, providing basic power for subsequent pressing operations.

[0073] Based on processing requirements, a suitable workstation is selected using a multi-station switching device. The rotary table is driven to rotate by a servo motor, and positioning pins ensure the accuracy of workstation switching.

[0074] The angle and position of roller 9 are adjusted by a multi-axis adjustment mechanism to accommodate groove designs of different shapes. A servo motor drives the rotating shaft 6 to ensure precise angle adjustment of roller 9.

[0075] As the mold disc and the fixed turntable approach each other, the conformal track 5 on the inner wall of the outer roller 10 begins to act on the roller seat 7. Individual balls contact the guide section of the conformal track 5, pushing the roller seat 7 towards the aluminum can along the sliding direction of the base 1, perpendicular to the central axis of the aluminum can. The roller 9 moves synchronously with the roller seat 7, gradually approaching the outer wall of the aluminum can and beginning to press the aluminum can.

[0076] During the pressing process, the multi-functional processing head can be changed as needed. For example, a scraper can be used to trim the grooves, or a polishing wheel can be used to polish the groove surface to improve the processing quality.

[0077] When a single ball enters the reset section of the conformal track 5, the contour change of the conformal track 5 causes the ball to move away from the aluminum can. The roller seat 7 resets synchronously with the ball, which in turn causes the roller 9 and the shoulder roller 8 to detach from the surface of the aluminum can. At this time, the mold disc separates from the fixed turntable in the opposite direction, and the aluminum can moves out of the pressing area with the mold disc, completing one groove pressing process.

[0078] After each pressing cycle, check the operating status of the multi-axis adjustment mechanism, multi-station switching device, and multi-functional processing head to ensure that each functional module is working properly. Perform maintenance and cleaning as necessary.

[0079] This embodiment integrates a multi-axis adjustment mechanism, a multi-station switching device, and a multi-functional processing head to meet diverse needs in aluminum can groove processing. The precise angle adjustment function of the multi-axis adjustment mechanism allows the groove shoulder to adapt to different groove shapes, improving equipment flexibility. The automatic switching function of the multi-station switching device reduces manual intervention and improves production efficiency. The multi-functional processing head design enables the groove shoulder to perform multiple processing tasks, enhancing equipment applicability. Furthermore, the multi-functional vertical direct-pressure groove shoulder is suitable for complex processes and diverse production needs, meeting the modern packaging industry's higher requirements for efficient and flexible processing.
