Description

Technical Field

[0001] This invention relates to the field of welding or cutting equipment or process technology, and in particular to a filter element circumferential seam welding device. Background Technology

[0002] In the existing filter element processing and manufacturing process, welding is a crucial step. Especially between the end caps and the outer shell of the filter element, or between the filter element body and the support frame, circumferential welding is often required to ensure sealing and robustness. However, most widely used filter element welding devices are based on the principle of spot welding or partial welding. This involves spot welding the workpiece at a fixed position using electrodes or welding heads, and then relying on a worker or a simple rotating mechanism to rotate the workpiece, thus completing the overall welding in the circumferential direction. This method has significant shortcomings: Firstly, spot welding is difficult to guarantee in terms of precision and consistency, and circumferential welds are prone to incomplete welds or uneven welds, directly affecting the sealing effect and service life of the filter element. Secondly, the rotation of the workpiece relies on a simple mechanical structure, resulting in insufficient positioning accuracy. Especially when filter element sizes vary, replacing and adjusting the device is time-consuming and labor-intensive, making it difficult to adapt to the mass production needs of different specifications. Furthermore, these devices are functionally limited, only capable of circumferential welding in a single direction, lacking pre-processing capabilities, and unable to meet the welding requirements when the filter element surface condition varies.

[0003] A more prominent problem is that existing filter element circumferential welding devices generally lack the function of pre-welding treatment of the workpiece. In actual production, filter elements often have scale, rust, moisture, or oil adhering to their surface due to transportation, storage, or preliminary processing. If these impurities are not removed in advance, they can easily lead to porosity, slag inclusions, or insufficient weld strength during welding, seriously reducing product quality. However, existing equipment mostly places the filter element directly on the welding fixture, lacking pre-processing such as rust removal, drying, and cleaning. This necessitates setting up an additional independent process during production, increasing labor and equipment costs and reducing production efficiency. At the same time, existing welding positions are mostly fixed at the top of the device, resulting in a single welding posture and making it difficult to adjust the welding angle and weld position according to different product structures, thus narrowing the applicability of the device. Especially given the wide variety and complex structure of filter elements, this type of fixed-position welding device cannot meet the actual needs of various situations. There is an urgent need for an improved filter element circumferential welding device that can take into account pre-welding treatment, welding flexibility, and weld quality.

[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a filter element circumferential seam welding device, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to design an improved filter element circumferential weld device that can take into account pre-welding treatment, welding flexibility, and weld quality.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A filter element circumferential weldment device includes a base, a drive box, a rotating jaw, a fixed rotating shaft, an adjustment assembly, a moving platform, an installation platform, and a welding mechanism. The base is mounted on the ground, the drive box is mounted on top of the base, and a drive component is installed inside the drive box. The rotating jaw is mounted on the output end of the drive box. The fixed rotating shaft is mounted on top of the base. Three adjustment assemblies are provided, respectively mounted on the side of the fixed rotating shaft, the side of the moving platform, and the side of the installation platform. The moving platform is mounted on top of the base and can slide laterally on the base. The installation platform is mounted on top of the moving platform, and the welding mechanism is mounted on top of the installation platform. The welding mechanism contains a rotating assembly that rotates under the drive of a drive gear, thereby adjusting the position distribution of the working components. This, in conjunction with the rotating jaw, drives the filter element workpiece to rotate, allowing for adaptive adjustments to complete the circumferential weldment process for different filter elements.

[0007] As a preferred embodiment of the filter element circumferential welding device of the present invention, the welding mechanism includes a mounting base plate, a fixing component, a rotating component, a connecting component, and a working component. The mounting base plate is mounted on the mounting platform and is double-sided clamped and fixed by the mounting platform. The fixing component is mounted on the mounting base plate. The rotating component is installed inside the fixing component and can rotate within the fixing component to adjust the angle of the working component. The connecting component is installed on the inner side of the rotating component and is used to install different working components to adapt to different working requirements. The working component is installed inside the connecting component. The working component is mainly a welding part and can also be configured as a rust remover nozzle, a high-pressure nozzle, or a hot air nozzle for welding the filter element and for pre-welding preparation.

[0008] In a preferred embodiment of the filter element annular seam welding device of the present invention, the fixing component is configured as an annular shape, including a fixing ring, a limiting groove, a rotating groove, an mounting groove, a drive gear, and a telescopic rod. The fixing ring is installed on the top of the mounting base plate by welding. The fixing ring is the main body of the fixing component. The limiting groove is located inside the fixing ring, and the rotating groove is located on the inner side of the fixing ring. The limiting groove and the rotating groove are annular structures to accommodate the rotating component. The mounting groove is located inside the fixing ring and is connected to the limiting groove. The drive gear is installed inside the mounting groove, with the drive gear on the side closest to the limiting groove. The drive gear can mesh with the rotating teeth on the rotating ring, and a micro motor inside the fixing ring drives the drive gear to rotate the rotating ring. The telescopic rod is located inside the fixing ring and can extend and retract within the limiting groove. A micro cylinder is provided at one end of the telescopic rod, allowing it to extend and retract.

[0009] As a preferred embodiment of the filter element circumferential welding device of the present invention, the limiting groove and the rotating groove are connected and the cross-sectional shape of their combination is "convex". The "convex" structure can help ensure the stability of the rotating component during rotation and improve the integrity of welding and pre-welding preparation. The cross-sectional shape of the telescopic rod is set to cross. The cross-shaped telescopic rod is conducive to being snapped into the control hole and the cross groove, thereby fixing the rotating component. The telescopic rods are arranged in a circumferential array. Multiple telescopic rods are used to stabilize the rotating component and improve the welding quality.

[0010] As a preferred embodiment of the filter element circumferential welding device of the present invention, the rotating assembly includes a rotating ring, rotating teeth, a control hole, and a cross groove. The rotating ring is installed inside the fixed assembly and is used to rotate under the drive of the drive gear, thereby moving different working components to a suitable position. The rotating teeth are set on the outer surface of the rotating ring and are used to cooperate with the drive gear, so that the rotating ring can rotate under the drive of the drive gear. The control hole is opened on the outer surface of the rotating ring, and the cross groove is opened on the inner side of the control hole. The control hole and the cross groove are configured with a telescopic rod. After the working component has rotated to the correct position, the telescopic rod is extended and engaged into the control hole and the cross groove to achieve clamping and fixation, ensuring stability during the welding process.

[0011] As a preferred embodiment of the filter element circumferential welding device of the present invention, the rotating assembly further includes a mounting hole, a cooling channel, and a conductive post. The mounting hole is located on the inner side of the rotating ring and is used to install the connecting device. The cooling channel is located inside the rotating ring and is circular. Water or other highly thermally conductive liquid is placed inside the cooling channel to cool the entire rotating assembly and ensure its temperature stability, thereby ensuring the working efficiency of various internal electronic components. The conductive post is installed in the mounting hole and has an insulating and waterproof layer on its outside. The two sides of the conductive post are respectively connected to the mounting hole and the control hole. The conductive post is used to connect the working component and the fixed component to provide power to the working component. Since the working component needs to rotate as needed, the traditional power supply line mode is easily messed up. In this solution, the power supply line is pre-embedded inside the fixed component, and a conductor is set in the middle of the telescopic pole. The telescopic pole, the connecting component, and the working component are electrically connected through the conductive post, realizing timely power supply.

[0012] As a preferred embodiment of the filter element circumferential welding device of the present invention, the connecting assembly includes a connecting sleeve, a mounting block, and a conductive block; the connecting sleeve is installed inside the rotating assembly, the mounting block is disposed on the inner side of the connecting sleeve, the conductive block is disposed at the bottom of the connecting sleeve, and the conductive block and the conductive post are electrically connected.

[0013] As a preferred embodiment of the filter element circumferential welding device of the present invention, the mounting block is configured as an arch shape, which can be used to engage and fix the mounting block and the positioning groove to ensure the working stability of the working component. The mounting blocks are arranged in a ring array on the inner side of the connecting sleeve. The conductive block is provided with a conductor coating on its surface. The conductor coating is used to electrically connect with the outer shell column to supply power to the working component.

[0014] As a preferred embodiment of the filter element circumferential welding device of the present invention, the working component includes a housing column, a working head, and a locking nut; the housing column is the main body of the working component, the lower part of the housing column is the power supply part, the bottom surface of the housing column is made of conductive material, the working head is located at one end of the housing column, and the working head can be configured as a welding head, a water spray head, or a high-pressure air gun head, thereby realizing welding, rust removal, drying and other processes as needed; the locking nut is installed on the outer side of the housing column and is used to limit the position of the working component.

[0015] As a preferred embodiment of the filter element circumferential welding device of the present invention, the working component further includes a positioning groove and a through groove; the positioning groove is formed on the outer surface of the outer shell column and is configured as an annular groove; the through groove is formed below the positioning groove and extends to the bottom surface of the outer shell column; when installing the working component, the mounting block can enter the positioning groove through the through groove and then be locked in place according to the shape of the two, so as to achieve quick installation, and at this time the bottom surface of the outer shell column and the top surface of the conductive block are in contact to achieve electrical connection.

[0016] The beneficial effects of this invention are: 1. This invention achieves continuous rotation and high-precision positioning of filter element workpieces during circumferential welding through the coordinated design of the rotating component and rotating jaws. The working component can be flexibly replaced with a welding head, rust removal nozzle, or high-pressure air gun head according to different process requirements, enabling the device to not only complete welding but also perform pre-weld treatment and drying processes, thereby improving the continuity and automation of the entire production process. This multi-functional integrated design effectively reduces manual operation and process changeover time, improves production efficiency, and is highly adaptable, meeting the processing needs of various filter element specifications.

[0017] 2. This invention employs a combined positioning design of telescopic poles, locking slots, and cross slots, supplemented by a power supply structure with conductive posts and built-in wires, achieving stable fixation and reliable power supply for the working component during rotation. A cooling channel is installed inside the rotating component, allowing for the circulation of a highly thermally conductive liquid to control the temperature of the entire rotating component, thereby ensuring the stability of electronic components and the working component during long-term continuous operation. These measures significantly improve welding precision and process reliability, ensuring uniform circumferential weld quality and reducing problems such as incomplete welds, porosity, or uneven weld seams.

[0018] 3. The invention features a compact and rational overall structure. The combination of the base, moving platform, and mounting platform enables flexible adjustment and multi-directional positioning of the workpiece and welding mechanism. Through the ring-shaped snap-fit ​​design and ring gear transmission, the device can quickly change and adjust the working components, achieving efficient switching between different processes. Simultaneously, the stable cooperation between the fixed, rotating, and working components ensures operational safety and reliability, significantly improving the device's versatility and applicability. This makes it suitable not only for traditional filter element welding but also for various complex processes, enhancing overall production efficiency and product quality.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figures 1-10As shown, a filter element circumferential welded device includes a base 1, a drive box 2, a rotating jaw 3, a fixed rotating shaft 4, an adjusting assembly 5, a moving platform 6, an mounting platform 7, and a welding mechanism 8. The device uses the base 1 as its main frame, which is mounted on the ground and provides stable support for the entire device, preventing vibration or displacement from affecting welding accuracy during the welding process. The drive box 2 is mounted above the base 1 and contains a drive component that provides power for rotation and welding actions. The output end of the drive box 2 is equipped with a rotating jaw 3, which clamps and drives the filter element workpiece to rotate, ensuring continuous and uniform circumferential welds during welding. To improve the stability and adaptability of the device, a fixed rotating shaft 4 is also mounted above the base 1. The fixed rotating shaft 4 limits the position of the workpiece, keeping it balanced during rotation and preventing shaking or displacement.

[0023] In terms of the adjustment mechanism design, the device is equipped with three adjustment components 5, which are respectively installed on the side of the fixed rotating shaft 4, the side of the moving platform 6, and the side of the mounting platform 7. Through the cooperation of these three sets of adjustment components 5, flexible adjustments can be made to the workpiece clamping angle, the position of the welding mechanism 8, and the platform's movement range, thereby meeting the welding requirements of filter element workpieces of different sizes and structures. The moving platform 6 is installed above the base 1 and can slide along the transverse track of the base 1. This structural design facilitates the adjustment of the relative position between the workpiece and the welding head, contributing to precise weld positioning. The mounting platform 7 is fixed above the moving platform 6, serving as the support platform for the welding mechanism 8 and providing a stable mounting foundation for the welding process.

[0024] like Figure 3 As shown, the welding mechanism 8 is mounted above the mounting platform 7, and a rotating component 83 is installed inside. Driven by the drive gear 825, the rotating component 83 can rotate, thereby flexibly adjusting the position distribution of the welding workpiece 85. This design effectively controls the movement trajectory of the welding head on the circumferential seam and, in conjunction with the synchronous drive of the rotating jaw 3, ensures that the welding mechanism 8 maintains a stable welding angle and uniform heat input while the filter element workpiece rotates. This not only guarantees the continuity and strength of the weld but also allows for adaptive adjustments for filter elements of different specifications, improving the versatility and flexibility of the device. Overall, this device, through the stable support of the base 1, the power output of the drive box 2, the workpiece rotation of the rotating jaw 3, the flexible adjustment of the adjusting component 5, and the precise control of the welding mechanism 8, enables a highly efficient, stable, and adaptable circumferential seam welding process for filter elements, significantly improving the problems of traditional equipment's single function, fixed welding position, and insufficient adaptability.

[0025] The welding mechanism 8 includes a mounting base plate 81, a fixing component 82, a rotating component 83, a connecting component 84, and a working component 85. The mounting base plate 81, serving as the load-bearing structure of the entire welding mechanism 8, is firmly mounted above the mounting platform 7 and is stably constrained by the double-sided clamping mechanism of the mounting platform 7. This structure effectively avoids uneven weld seams caused by vibration or displacement during welding, ensuring welding accuracy and reliability. The fixing component 82 is located above the mounting base plate 81, providing mounting space and support for the rotating component 83. The rotating component 83 is installed inside the fixing component 82, enabling smooth rotation within the fixing component 82, thereby driving the connecting component 84 and the working component 85 below to adjust their angles. Through the design of the rotating component 83, the working component 85 can flexibly change the welding angle and welding path, allowing the device to not only complete welding at a single location but also perform circumferential or multi-angle welding operations depending on the workpiece structure.

[0026] Furthermore, the connecting component 84 is installed on the inner side of the rotating component 83. The function of the connecting component 84 is to provide an installation interface for different working components 85, enabling the entire device to have good compatibility and expandability. By replacing different working components 85, the welding mechanism 8 can adapt to various production process requirements. The working components 85 are installed inside the connecting component 84. Typically, the working components 85 are mainly configured as welding parts, used to complete the circumferential welding operation of the filter element. At the same time, depending on the actual process requirements, the working components 85 can also be replaced with rust remover nozzles, high-pressure nozzles, or hot air nozzles to respectively achieve rust removal and cleaning of the filter element surface, impurity blowing, and pre-welding drying. This multi-functional design greatly enhances the applicability of the welding mechanism 8, enabling the device not only to complete high-quality welding but also to undertake the key pre-welding treatment, thereby improving the continuity of the overall process and production efficiency.

[0027] like Figure 5As shown, the fixing component 82 is configured as a circular structure, mainly including a fixing ring 821, a limiting groove 822, a rotating groove 823, a mounting groove 824, a drive gear 825, and a telescopic pole 826. The fixing ring 821, as the main body of the fixing component 82, is firmly installed on top of the mounting base plate 81 using welding, ensuring sufficient stability and load-bearing capacity during operation and preventing loosening due to external forces or mechanical vibration. The fixing ring 821 acts as the core framework of the overall structure, with a limiting groove 822 and a mounting groove 824 inside, and a rotating groove 823 on its inner side. Both the limiting groove 822 and the rotating groove 823 are circular structures. The circular design facilitates the containment and restriction of the rotating component 83, allowing it to maintain stable rotation under the constraint of the fixing ring 821, preventing displacement or detachment. Meanwhile, the limiting groove 822 is not only used to limit the movement trajectory of the rotating component 83, but also, with the cooperation of the telescopic pole 826, to further position and fix the rotating component 83, thereby improving the overall operating accuracy.

[0028] An installation groove 824 is provided inside the fixed ring 821, which communicates with the limiting groove 822, providing installation space for the drive gear 825. The drive gear 825 is installed inside the installation groove 824 and positioned close to the limiting groove 822, allowing it to directly mesh with the rotating teeth 832 on the rotating ring 831. Through this gear transmission, when the micro-motor inside the fixed ring 821 is activated, it drives the drive gear 825 to rotate, thereby driving the rotating ring 831 and causing the rotating component 83 to rotate stably along a preset trajectory. This achieves angle adjustment of the working component 85 and continuity of circumferential welding. This design is compact, has high transmission efficiency, effectively reduces energy loss, and ensures rotational synchronization.

[0029] In addition, the fixed assembly 82 is equipped with a telescopic pole 826, which can extend and retract within the limiting groove 822. One end of the telescopic pole 826 is connected to a miniature cylinder, which drives the extension and retraction of the pole. During operation, the telescopic pole 826 not only provides auxiliary support for the rotating assembly 83 but can also be locked and released when necessary, improving the flexibility and safety of the device under different working conditions. Overall, the fixed assembly 82, through the stable support of the fixed ring 821, the precise constraint between the limiting groove 822 and the rotating groove 823, the efficient transmission of the drive gear 825, and the auxiliary positioning of the telescopic pole 826, achieves stable driving and multi-angle adjustment of the rotating assembly 83, providing a solid guarantee for the reliable operation of the welding mechanism 8.

[0030] The limiting groove 822 and the rotating groove 823 are interconnected, and the cross-sectional shape formed after their combination is designed as a "convex" shape structure. The geometric characteristics of this "convex" shape can provide multi-directional limiting support during the rotation of the rotating component 83, enabling the rotating component 83 to always operate within a predetermined trajectory and preventing it from shaking or shifting due to inertia or external disturbances. This not only ensures the continuity and stability of the weld seam during welding but also enables the preparatory work such as rust removal, cleaning, and drying before welding to be successfully completed, further enhancing the integrity and reliability of the overall process.

[0031] In terms of the fixing method, the cross-sectional shape of the telescopic electric rod 826 is designed as a cross shape. Compared with ordinary circular or rectangular cross-sections, the cross-shaped cross-section is more likely to achieve precise clamping and alignment with the control hole 833 and the cross groove 834, thereby effectively improving the firmness of the fixation. The telescopic electric rods 826 are distributed inside the fixing ring 821 in a circumferential array. By simultaneously acting on the rotating component 83 through multiple telescopic electric rods 826, uniform support and restraint can be provided in different directions of the rotating component 83, preventing it from experiencing eccentric rotation. This design not only significantly improves the stability of the rotating component 83 during operation but also plays a key role in enhancing the weld seam uniformity and welding quality, providing a structural guarantee for the whole machine to achieve high-precision and high-reliability circumferential welding.

[0032] As Figure 6-8 shown, the rotating component 83 mainly consists of a rotating ring 831, rotating teeth 832, a control hole 833, and a cross groove 834. The rotating ring 831 is installed inside the fixing component 82 and is the main part of the rotating component 83. Its main function is to achieve smooth rotation under the drive of the driving gear 825, thereby moving different types of working components 85 one by one to appropriate working positions. In this way, the device can flexibly switch different functional modules on the same platform, such as welding parts, rust removal nozzles, or drying nozzles, to meet the continuous processing requirements of different processes. To achieve reliable transmission, rotating teeth 832 are uniformly arranged on the outer surface of the rotating ring 831. The rotating teeth 832 form a meshing relationship with the driving gear 825. When the driving gear 825 rotates, it can effectively drive the rotating ring 831 to rotate self, and ensure the smoothness and synchronism of its rotation, thereby preventing slipping or uneven rotation.

[0033] For positioning and fixing, the outer surface of the rotating ring 831 is provided with several control holes 833, and the inner side of each control hole 833 is further provided with a cross groove 834. This design allows the control holes 833 and the cross groove 834 to work together with the telescopic pole 826. When the rotating ring 831 completes a predetermined angle of rotation and rotates the target working component 85 to the designated working position, the telescopic pole 826 can extend under control command and engage with the control holes 833 and the cross groove 834. Due to the special geometry of the cross groove 834, which provides multi-directional limiting effect, the telescopic pole 826 can form a firm locking effect on the rotating ring 831 after engagement, preventing it from shifting due to vibration or force during welding or pre-welding treatment. This structure not only effectively ensures the stability of the welding process but also improves the uniformity of the weld and the reliability of the process. Overall, the rotating component 83, through its design of "driving rotation + precise positioning + reliable locking", enables the working component 85 to be quickly switched and securely fixed between different workstations, providing important support for the multi-functionality and high-precision welding of the device.

[0034] like Figure 9 As shown, the rotating assembly 83 also includes additional structures such as mounting holes 835, cooling channels 836, and conductive posts 837 to further enhance its functional versatility and operational stability. Specifically, the mounting holes 835 are formed on the inner surface of the rotating ring 831. The function of the mounting holes 835 is to provide a reliable mounting position for the connecting assembly 84, allowing the connecting assembly 84 to be securely embedded therein, thereby facilitating the replacement and installation of different working components 85. Through this structural arrangement, the versatility and expandability of the rotating assembly 83 in the assembly process can be effectively improved, meeting the needs of various welding and pre-welding treatment processes.

[0035] To prevent performance degradation of the rotating component 83 due to temperature rise during prolonged operation, a cooling channel 836 is incorporated internally. This cooling channel 836 is arranged in a circular, surrounding pattern and can be filled with water or other highly thermally conductive liquids, such as cooling oil or liquid metal coolant. These highly thermally conductive liquids rapidly absorb and conduct the heat generated during operation, thus cooling the entire rotating component 83. The cooling circulation through the cooling channel 836 effectively ensures the temperature stability of the rotating component 83, preventing damage to electronic components or decreased precision due to overheating. This, in turn, ensures the internal electrical components operate at high efficiency for extended periods, significantly improving the durability and continuous operation capability of the device.

[0036] Furthermore, the rotating component 83 is internally designed with conductive posts 837, which are installed in the mounting hole 835 and covered with an insulating and waterproof layer to ensure power transmission while preventing safety hazards such as short circuits or leakage. The two ends of the conductive post 837 communicate with the mounting hole 835 and the control hole 833, respectively, enabling electrical connection between the working component 85 and the fixed component 82. Since the working component 85 needs to rotate with the rotating ring 831 during use, a traditional power supply line would easily suffer from cable twisting, tangling, or excessive bending, affecting its lifespan and even causing power outages. This solution innovatively embeds the power supply line inside the fixed component 82, while a conductor is installed in the middle of the telescopic pole 826, with the conductive post 837 extending and connecting the conductive path. Thus, when the telescopic pole 826 cooperates with the connecting component 84 and the working component 85, power can be transmitted to the working component 85 in a timely and stable manner, ensuring continuous power supply to the welding components or nozzle components.

[0037] In summary, the rotating component 83 achieves efficient docking with the connecting component 84 through the mounting hole 835, achieves precise temperature control of the overall system through the cooling channel 836, and solves the problem of power supply for rotation through the conductive post 837 combined with internal wiring. This design not only ensures the long-term stable operation of the rotating component 83 under complex working conditions, but also enables the working component 85 to maintain a reliable working state in high-intensity continuous operation environments, thereby significantly improving welding quality and the overall service life of the device.

[0038] like Figure 10 As shown, the connecting assembly 84 mainly comprises three parts: a connecting sleeve 841, a mounting block 842, and a conductive block 843. The connecting sleeve 841 is installed inside the rotating assembly 83, serving as the main structure for support and positioning, providing a stable mounting base for different working components 85. The mounting block 842 is located on the inner side of the connecting sleeve 841, used to limit and lock the inserted working component 85, preventing it from shaking or falling off during operation and ensuring the stability of welding and pretreatment operations. The conductive block 843 is installed at the bottom of the connecting sleeve 841 and achieves a reliable electrical connection with the conductive post 837, thereby smoothly transferring electrical energy to the inside of the working component 85, providing continuous and stable power support for welding components or other functional nozzles.

[0039] The mounting blocks 842 are designed with an arched structure. This arched design allows for a tighter and more secure engagement with the locking slots 854, effectively preventing loosening due to vibration or stress during operation and further enhancing the overall stability and reliability of the working component 85. The mounting blocks 842 are evenly distributed in a ring array on the inner side of the connecting sleeve 841. This arrangement not only ensures uniform force distribution on each block and extends its service life, but also provides more convenient operating space when disassembly or installation is required. The upper surface of the conductive block 843 is covered with a conductive coating, which reduces contact resistance and enhances conductivity, ensuring stable current transmission. The conductive coating is reliably electrically connected to the outer casing post 851, enabling efficient power transmission to the working component 85, providing continuous and stable power support, and ensuring the entire device maintains efficient and safe operation.

[0040] The working assembly 85 comprises three parts: a housing column 851, a working head 852, and a locking nut 853. The housing column 851, as the main body of the working assembly 85, possesses excellent strength and stability, providing reliable support for all components during operation. The lower part of the housing column 851 is designed as a power supply section, with its bottom surface made of a highly conductive material, ensuring stable power transmission when in contact with the conductive block 843, guaranteeing a continuous supply of power to the working head 852. The working head 852 is mounted at one end of the housing column 851 and can be flexibly replaced according to different process requirements. For example, when configured as a welding head, it enables efficient welding of filter element circumferential seams; when configured as a water spray head, it can clean or remove rust from workpieces; and when configured as a high-pressure air gun head, it can quickly dry the workpiece surface, providing multi-functional process support. The locking nut 853 is installed on the outer side of the housing column 851. Its main function is to limit and fix the working component 85 to prevent displacement or loosening during operation, and to ensure that the entire device can maintain a stable, safe and efficient operating state.

[0041] The working component 85 also includes two structural parts: a locking groove 854 and a passage groove 855. These two parts work together to enable quick installation and secure fixation of the working component 85. Specifically, the locking groove 854 is formed on the outer surface of the housing post 851 and is designed as an annular groove structure. This annular groove provides a precise limiting position for the mounting block 842, ensuring that the housing post 851 does not shift during operation. The passage groove 855 is formed below the locking groove 854 and extends axially along the housing post 851 to its bottom surface. During installation, the mounting block 842 can be smoothly inserted through the passage groove 855, then enters the locking groove 854, and finally achieves a tight snap-fit ​​fixation based on the geometry of both parts. This design not only improves the efficiency of assembly and disassembly of the working component 85 but also greatly enhances the reliability of the connection. Meanwhile, when the outer casing post 851 is fixed in the slot 854, its bottom surface will be in close contact with the upper surface of the conductive block 843, thereby completing the electrical connection, so that electrical energy can be efficiently transferred to the inside of the working component 85, ensuring its stable operation under different working conditions.

[0042] In operation, the filter element circumferential welder of this invention mainly includes several steps: workpiece installation, station adjustment, welding and pre-welding treatment, and the rotating component 83 driving the working component 85 to complete the circumferential weld. First, the filter element workpiece to be welded is placed in the rotating jaw 3, which clamps and fixes the workpiece. Simultaneously, the fixed rotating shaft 4 provides additional positioning support to ensure the workpiece remains stable during rotation. The moving platform 6 can be adjusted laterally via the adjusting component 5 according to the workpiece size. The mounting platform 7 carries the welding mechanism 8 and performs high-precision positioning, ensuring the relative position between the welding mechanism 8 and the workpiece reaches the optimal state.

[0043] During welding or pretreatment, the operator first determines an adaptive plan based on the filter element's condition. The working head 852 of the working component 85 is configured with the corresponding rust remover nozzle, high-temperature air gun, and welding head. The rust remover nozzle and high-temperature air gun are activated to treat the filter element joints. Then, the welding head is activated for welding. Before welding begins, the welding point location needs to be determined. The telescopic rod 826 is first disengaged from the control hole 833 and cross groove 834, and the drive gear 825 is activated to drive the rotating ring 831 to rotate, thus achieving continuous circumferential movement of the working component 85. After the working component 85 reaches the designated position, the power supply to the drive gear 825 is paused, and the telescopic rod 826 is extended and engaged into the control hole 833 and cross groove 834, establishing the circuit connection of "telescopic rod 826 - conductive post 837 - conductive block 843 - outer shell post 851 - working head 852," thus providing power to the working component 85. This ensures stable welding or spraying processes. The cooling channel 836 inside the rotating component 83 circulates a highly thermally conductive liquid, ensuring the temperature stability of the rotating component 83 and preventing overheating of electronic components. After rotation, the telescopic rod 826 engages with the control hole 833 and the cross groove 834 to lock and fix the working component 85, further improving welding accuracy. During welding, the rotating jaw 3 and the fixed rotating shaft 4 drive the filter element workpiece to rotate synchronously, thereby achieving circumferential welding.

[0044] The working principle of this invention is based on the coordinated movement of the rotating component 83 and the working component 85. The rotating ring 831 is driven by a gear 825, enabling the working component 85 to move along the circumference of the filter element. This, combined with the outer shell column 851 and the working head 852, completes welding or pretreatment operations. Simultaneously, electrical energy is transmitted to the working component 85 through the conductive column 837, conductive block 843, and built-in wires, achieving efficient power supply to the welding head or nozzle. The telescopic pole 826 provides positioning and fixing functions, while the cooling channel 836 ensures stable system temperature, thereby achieving high-precision welding and multi-functional processing of the filter element's circumferential seams. The overall process emphasizes the synchronization of workpiece rotation, working component 85 movement, and power supply to ensure welding quality and device reliability.
