[0025] The core of this utility model is to provide a pneumatic control system for a composite filter rod assembly machine. The pneumatic control system of the composite filter rod assembly machine adopts a modular design, which is convenient to adapt to different cigarette manufacturing processes.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , Figure 1 A schematic diagram of the pneumatic control system for the pre-jointing device of a multi-component filter rod joining machine; Figure 2 A schematic diagram of the pneumatic control system for the splicing device of a multi-component filter rod splicing machine; Figure 3 A front view of the pneumatic control system provided in a specific embodiment of this utility model. Figure 4 This is a side view of the pneumatic control system provided in a specific embodiment of the present invention.

[0028] In one specific embodiment, the pneumatic control system of the composite filter rod assembly machine provided by this utility model includes a pre-joining pneumatic control unit 1 and a joining pneumatic control unit 10 connected to an air source through an air inlet. Both the pre-joining pneumatic control unit 1 and the joining pneumatic control unit 10 have multiple branch air outlets. It also includes a cooling section pneumatic control unit 4, a hollow section pneumatic control unit 3, a smoke generation section pneumatic control unit 2, and a filter section pneumatic control unit 5, each connected to one of their respective branch air outlets through their air inlets. Furthermore, it includes a cooling section base rod supply pneumatic control unit 8, a hollow section base rod supply pneumatic control unit 7, a smoke generation section base rod supply pneumatic control unit 6, and a filter section base rod supply pneumatic control unit 9, which are connected one-to-one with the air outlets of the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, the smoke generation section pneumatic control unit 2, and the filter section pneumatic control unit 5.

[0029] In the above structure, the pneumatic control system includes multiple modular pneumatic control units. The air inlets of the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10 are connected to the main air source, providing air to the pre-jointing device and the joining device. The pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10, as main air source distribution units, have multiple branch air outlets responsible for providing air to subsequent functional sections. Specifically, the multiple branch air outlets of these two units are respectively connected to the pneumatic control units of the cooling section, the hollow section, the smoke generation section, and the filter section, providing air to the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, the smoke generation section pneumatic control unit 2, and the filter section pneumatic control unit 5.

[0030] The outlet of the cooling section pneumatic control unit 4 is connected to the cooling section base rod supply pneumatic control unit 8, and the air source for the cooling section base rod supply pneumatic control unit 8 is provided by the cooling section pneumatic control unit 4. The outlet of the hollow section pneumatic control unit 3 is connected to the hollow section base rod supply pneumatic control unit 7, and the air source for the hollow section base rod supply pneumatic control unit 7 is provided by the hollow section pneumatic control unit 3. The outlet of the smoke-generating section pneumatic control unit 2 is connected to the smoke-generating section base rod supply pneumatic control unit 6, and the air source for the smoke-generating section base rod supply pneumatic control unit 6 is provided by the smoke-generating section pneumatic control unit 2. The outlet of the filter section pneumatic control unit 5 is connected to the filter section base rod supply pneumatic control unit 9, and the air source for the filter section base rod supply pneumatic control unit 9 is provided by the filter section pneumatic control unit 5.

[0031] The pneumatic control system of the composite filter rod assembly machine provided by this utility model adopts a modular design. Regardless of the layout of the new tobacco products or the type of equipment required by the customer (e.g., some require cooling, hollow core, smoke generation, and filter rods, while others only require three types of base rods rolled together, or the order of the four base rods varies, to produce a qualified ternary or quaternary heated cigarette product, cigarette manufacturers have multiple process routes to choose from: "1+1+1+1", "1+1+1", "2+1", "2+2", "3+1", "3+0", "4+0", etc.), the corresponding pneumatic system can be quickly configured according to different process routes without redesigning. Without disassembling the entire system, the pneumatic components can be arbitrarily interchanged, making it flexible, versatile, and easy to install. It not only meets basic production needs but also reduces the complexity and maintenance difficulty of the system.

[0032] Based on the above specific embodiments, the air inlets of the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, and the smoke generation section pneumatic control unit 2 are connected to the air outlet of the pre-twisting pneumatic control unit 1, and the air inlet of the filter section pneumatic control unit 5 is connected to the air outlet of the twisting pneumatic control unit 10.

[0033] In one specific embodiment, the air source for the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, and the smoke generation section pneumatic control unit 2 is provided by the pre-jointed pneumatic control unit 1. The pre-jointed pneumatic control unit 1 provides a unified air source distribution for these units, ensuring that the pneumatic components of each unit can obtain stable pressure and flow.

[0034] The air source for the filter section pneumatic control unit 5 is provided by the splicing pneumatic control unit 10, and the air source is adjusted independently by the splicing pneumatic control unit 10.

[0035] The pre-jointing pneumatic control unit 1 and the jointing pneumatic control unit 10 serve as the core of the air source distribution, providing stable air source support for the gas control units of different functional sections, which can ensure the efficient operation of the pneumatic system.

[0036] Based on the above specific embodiments, the air inlet of the stitching pneumatic control unit 10 is connected to one air outlet of the pre-stitching pneumatic control unit 1.

[0037] In one specific embodiment, the pre-jointing pneumatic control unit 1 can provide air supply not only to the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, and the smoke-generating section pneumatic control unit 2, but also to the joining pneumatic control unit 10 and the filter section pneumatic control unit 5. In this case, the air inlet of the joining pneumatic control unit 10 can be connected only to the air outlet of the pre-jointing pneumatic control unit 1. As the main air source distribution unit of the entire system, the pre-jointing pneumatic control unit 1 centrally manages the air source of all units. By adjusting its output pressure and flow rate, it can uniformly manage the pneumatic requirements of the entire system, reducing problems caused by mismatched air source pressure or flow rate. The air source of the joining pneumatic control unit 10 is directly obtained from the pre-jointing pneumatic control unit 1, reducing the need for additional air source processing units or branch air paths, simplifying the air path layout, and reducing the complexity of air source distribution. Centralized management makes it easier to filter, depressurize, and lubricate the air source, thereby improving system reliability and maintenance efficiency. The modular design facilitates system expansion or modification as needed. For example, if more functional units are needed in the future, a branch can be added directly at the air outlet of the pre-connected pneumatic control unit 1.

[0038] It should be noted that the pneumatic control unit 10 for pre-jointing can also be connected to an air source at the same time, and the air inlet of the pneumatic control unit 5 for the filter section can also be connected to the pneumatic control unit 10 for pre-jointing. If the pressure or flow of the pneumatic control unit 1 for pre-jointing is insufficient, an air source can be provided for the pneumatic control unit 10 for pre-jointing and the pneumatic control unit 5 for the filter section as an alternative solution to meet the needs of all connected units.

[0039] Based on the above specific embodiments, an air source processing unit is also included, which is connected between the air source and the pre-twisting pneumatic control unit 1 and the twisting pneumatic control unit 10. There are two air source processing units, wherein the first air source processing unit 11 is connected to the pre-twisting pneumatic control unit 1 and the second air source processing unit 12 is connected to the twisting pneumatic control unit 10.

[0040] In one specific embodiment, two air sources are respectively connected to a first air source processing unit 11 and a second air source processing unit 12. The first air source processing unit 11 is connected between the air source and the pre-jointing pneumatic control unit 1. The second air source processing unit 12 is connected between the air source and the joining pneumatic control unit 10. Through these two independent air source processing units, the parameters of the two air sources can be adjusted and optimized separately to meet the needs of different functional stages, providing high-quality air sources for both the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10. For example, the pre-jointing stage may require lower pressure and higher flow rate, while the joining stage may require higher pressure and a stable airflow.

[0041] The primary function of the air source preparation unit is to ensure that the quality, pressure, and flow rate of compressed air meet the requirements of the pneumatic control unit. The air source preparation unit typically includes a filter and a pressure reducing valve. The filter removes impurities and moisture from the compressed air, ensuring air cleanliness. The pressure reducing valve regulates the air source pressure to the rated pressure required by the pneumatic components and maintains pressure stability, ensuring the normal operation of the pre-connected pneumatic control unit 1 and the connection pneumatic control unit 10. The air source preparation unit is usually installed near the air-consuming equipment, directly connecting between the air source and the pneumatic control unit. Its modular design makes installation and maintenance more convenient, and the configuration can be flexibly adjusted as needed.

[0042] Based on the above specific embodiments, the air outlet of the stitching pneumatic control unit 10 is connected to the air inlet of the pre-stitching pneumatic control unit 1.

[0043] In one specific embodiment, to provide a backup air source, the air inlet of the pre-jointing pneumatic control unit 1 can be connected to both the air source and the air outlet of the joining pneumatic control unit 10. The air source for the joining pneumatic control unit 10 comes from the second air source processing unit 12, and its air outlet is connected to the air inlet of the pre-jointing pneumatic control unit 1 as a backup air source. In the event of a main air source failure or insufficient main air source pressure, the system's continuous operation is ensured by switching to the air outlet of the joining pneumatic control unit 10 as a backup air source.

[0044] Two independent gas sources and gas processing units provide redundancy. If the first gas source or the first gas processing unit 11 fails, the system can switch to the second gas source and the second gas processing unit 12, thus ensuring continuous system operation. Gas source switching can be controlled automatically or manually, for example, through solenoid valves or mechanical switching valves, ensuring a smooth transition of the gas source and avoiding equipment failure due to pressure fluctuations.

[0045] Based on the above specific embodiments, both the pre-stitching pneumatic control unit 1 and the stitching pneumatic control unit 10 have at least two parallel air inlets, one of which is connected to the first air source processing unit 11 and the other is connected to the second air source processing unit 12.

[0046] In one specific embodiment, the first air source processing unit 11 is connected to a first air source, and after filtration, pressure reduction, and lubrication, provides an air source for the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10. The second air source processing unit 12 is connected to a second air source, and after similar processing, provides a backup air source for the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10. Similarly, the first air source processing unit 11 can provide a backup air source for the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10, while the second air source processing unit 12 provides an air source for the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10.

[0047] One air inlet of the pre-jointing pneumatic control unit 1 is connected to the first air source processing unit 11, and the other air inlet is connected to the second air source processing unit 12. One air inlet of the joining pneumatic control unit 10 is connected to the first air source processing unit 11, and the other air inlet is connected to the second air source processing unit 12. Both the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10 receive air from the source through two parallel air inlets, ensuring a seamless switch to the other air source in the event of a failure in one air source or air source processing unit.

[0048] The first and second air source processing units safeguard the backup air source. By connecting two air inlets in parallel, the system has redundancy. When the main air source fails, it can switch to the backup air source, ensuring the continuity of the production process, improving the reliability and stability of the system, and reducing downtime caused by air source interruptions.

[0049] Based on the above specific embodiments, the first air source processing unit 11 is located directly behind the pre-jointing pneumatic control unit 1 and is connected via a rubber hose, and the second air source processing unit 12 is located directly behind the jointing pneumatic control unit 10 and is connected via a rubber hose.

[0050] In one specific embodiment, the first air source processing unit 11 and the second air source processing unit 12 are located directly behind the pre-jointing pneumatic control unit 1 and the jointing pneumatic control unit 10, respectively. By placing the air source processing units directly behind their respective pneumatic control units, the complexity of the air path is reduced, and pressure loss in the air path is lowered. This layout makes the entire system structure more compact, saves space, and shortens the length of the connecting pipes between the air source processing units and the pre-jointing pneumatic control units 1 and 10. Connecting the first air source processing unit 11 and the second air source processing unit 12 to the pre-jointing pneumatic control units 1 and 10 is also more convenient. The pneumatic control units are connected by flexible hoses to achieve rapid and convenient air supply.

[0051] Based on the above specific embodiments, the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, the smoke generation section pneumatic control unit 2, the pre-jointing pneumatic control unit 1, the filter section pneumatic control unit 5, and the joining pneumatic control unit 10 are arranged in sequence.

[0052] In one specific embodiment, the base rods cut by the cooling section base rod cutting device are transferred to the hollow section base rod cutting device, and together with the base rods cut by the hollow section base rod cutting device, they move to the smoke generation section base rod cutting device, and together with the base rods cut by the smoke generation section base rod cutting device, they move to the pre-jointing device for pre-jointing processing. The base rods from both the pre-jointing device and the filter section base rod cutting device enter the joining device for joining processing. Therefore, the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, and the smoke generation section pneumatic control unit 2 are located on the first side of the pre-jointing pneumatic control unit 1, with the cooling section pneumatic control unit 4 being the furthest from the first side of the pre-jointing pneumatic control unit 1, and the smoke generation section pneumatic control unit 2 being the closest to the first side of the pre-jointing pneumatic control unit 1. The filter section pneumatic control unit 5 and the joining pneumatic control unit 10 are located on the other side of the pre-jointing pneumatic control unit 1, and the various pneumatic control units are arranged horizontally in sequence. By arranging the pneumatic control units sequentially, the system can realize a continuous process flow from cooling, hollow core, smoke generation, pre-twisting, filter tip to twisting, which facilitates system integration and management, while ensuring the coordinated operation between the functional sections.

[0053] Based on the above specific embodiments, the pre-jointing pneumatic control unit 1 is located in the upper part of the pre-jointing device, the joining pneumatic control unit 10 is located in the upper part of the joining device, and the connecting pipes of the pre-jointing pneumatic control unit 1, the cooling section pneumatic control unit 4, the hollow section pneumatic control unit 3, and the smoke generation section pneumatic control unit 2 are arranged in sequence at their heights.

[0054] In one specific embodiment, the pre-jointing pneumatic control unit 1 and the joining pneumatic control unit 10 are located in the upper part of their respective devices. Centralizing the pneumatic control units in the upper part of the device allows maintenance personnel easier access and operation of these units, facilitating maintenance and repair. The piping connections of the cooling section, hollow section, and smoke generation section pneumatic control units are arranged sequentially. Piping connections should avoid crossing to ensure unobstructed airflow. This effectively utilizes vertical space, reduces the floor space, and achieves space optimization and process continuity. Optimized piping layout reduces pressure loss during airflow transmission, improving the overall system efficiency.

[0055] The air inlet and outlet of the pneumatic control unit can use standard threaded interfaces or quick couplings. When connecting, ensure the interface is sealed; O-rings or sealant can be used.

[0056] Based on the above specific embodiments, the pneumatic control unit 8 for supplying the base rod of the cooling section, the pneumatic control unit 7 for supplying the base rod of the hollow section, the pneumatic control unit 6 for supplying the base rod of the smoke generation section, and the pneumatic control unit 9 for supplying the base rod of the filter section are respectively arranged directly above the pneumatic control unit 4 for supplying the base rod of the cooling section, the pneumatic control unit 3 for supplying the base rod of the hollow section, the pneumatic control unit 2 for supplying the smoke generation section, and the pneumatic control unit 5 for supplying the base rod of the filter section, with the corresponding connecting pipes along the vertical direction.

[0057] In one specific embodiment, the base rod supply pneumatic control unit is located directly above the corresponding functional section pneumatic control unit for convenient material supply. At the same time, the entire system is laid out vertically, effectively utilizing vertical space and reducing the floor area. The vertically arranged pipelines and centralized control units make maintenance and repair more convenient. The vertical connecting pipelines reduce bends and resistance in the airflow transmission process, thereby reducing pressure loss and improving the overall efficiency of the system.

[0058] The pneumatic control device of the pneumatic control system provided by this utility model includes a panel and components connected to the panel. The pneumatic components are connected by air pipes. The panel includes a frame composed of two vertical profiles and two horizontal profiles, as well as horizontal and vertical profiles connected within the frame. The components are connected to the profiles by connectors, and the profiles and connectors are slidably connected.

[0059] In the above structure, the pneumatic control device is applied in equipment for the production of new tobacco products. Components are connected to the panel and include an air source device, valve island, pressure reducing valve, precision pressure reducing valve, throttle valve, throttle valve mounting plate, pressure sensor, fine filter, solenoid valve, pneumatic control valve, air distribution block, air pipe connectors, air circuit accessories, and other pneumatic components. These components are conventional parts in existing technology. The air source device provides the system with stable and clean compressed air. Pneumatic components are connected by air pipes, typically made of nylon, polyurethane, or rubber, which offer good flexibility and pressure resistance. The air pipes can be connected to the component interfaces via quick-connect fittings, ensuring reliable and airtight connections while facilitating quick disassembly and replacement. The electrical program controls the valve plate's movement, thereby controlling the movement of each pneumatic actuator; the pressure reducing valve and precision pressure reducing valve adjust the pressure of each branch; the throttle valve regulates the flow rate of each branch; the pressure sensor digitally displays the pressure of the main line and branches and can upload the data; the gas passing through the fine filter can be used for components with high gas requirements.

[0060] Two vertical profiles serve as the main supporting structure for the panel. Two horizontal profiles connect with the vertical profiles to form a rectangular frame. The frame internally contains both horizontal and vertical profiles to further reinforce the structure and provide more mounting positions for components. The profiles are typically made of aluminum alloy or high-strength steel, possessing good mechanical properties and corrosion resistance.

[0061] Components are secured to the profile via connectors. These connectors are typically designed with a sliding structure, such as a slider or adjusting nut, allowing the component to slide and adjust its position along the length of the profile. This sliding connection between the profile and the connector allows for flexible adjustment of the component's mounting position according to actual needs. After adjustment to the appropriate position, the connector is secured to the profile using bolts or locking devices to ensure the component remains stable during operation.

[0062] The pneumatic control device provided by this invention can integrate various components, which are easy to install and disassemble, facilitating quick replacement and maintenance and reducing equipment downtime. The panel is made of profile material, eliminating the need for drilling. The sliding connection design allows for adjustment of component installation positions according to specific equipment needs, enabling flexible installation and adjustment, facilitating optimized layout and functional expansion. It supports modular design, allowing different functional modules to be installed and debugged independently, facilitating equipment upgrades and maintenance. The robust design of the profile and connectors ensures system stability, maintaining performance even under frequent adjustments and long-term operation. It is particularly suitable for the complex automation control requirements of tobacco product equipment, effectively improving equipment operating and maintenance efficiency.

[0063] The profile and connector include at least two connection methods. In the first method, the profile includes a front groove, one end of the connector has a slider and the other end has a connecting part, the slider is inserted into the front groove and slidably connected with the front groove, and the components are connected to the connecting part.

[0064] In one specific embodiment, the profile serves as the frame foundation of the pneumatic control device. The profile has a front groove for mounting and securing connectors. The connector is a key component for fixing elements to the profile. One end of the connector has a slider that inserts into the front groove on the profile and slides within it. This sliding connection allows the connector to move freely along the groove on the profile. The other end of the connector has a connecting portion for securing elements, such as by bolts or other fixing methods. This allows the position of components to be adjusted according to actual needs, optimizing the layout of the pneumatic system.

[0065] Preferably, the front groove can be a T-groove or a dovetail groove, which facilitates the installation of the connector and prevents the slider from falling out of the groove.

[0066] In the second method, the connector is a sliding sleeve fitted onto the profile, and the components are connected to the connecting part of the sliding sleeve, so that the sliding sleeve and the profile are slidably connected.

[0067] In one specific embodiment, a sliding sleeve is a type of connector whose main function is to fix components to a profile and allow the components to slide along the profile to adjust their position. The sliding sleeve includes a sliding portion, a connecting portion, and a locking device. The sliding sleeve is fitted onto the profile, and its internal shape matches the outer shape of the profile. The internal part of the sliding sleeve is clearance-fitted with the profile to ensure that the sliding sleeve can move freely and slide smoothly along the length of the profile. To ensure smooth sliding between the sliding sleeve and the profile, ball bearings can be provided between the sliding sleeve and the profile.

[0068] A connecting part can be provided at one end or on the side of the sliding sleeve for fixing pneumatic components. The connecting part is usually designed with threaded holes, mounting grooves or other fixing structures, and the components are fixed to the connecting part of the sliding sleeve by bolts, nuts or other fasteners.

[0069] To ensure the sleeve is securely fixed to the profile after being adjusted to the correct position, it is typically equipped with a locking device, such as a locking screw or locking nut. By tightening the locking device, the sleeve is firmly secured to the profile, preventing it from loosening during operation.

[0070] Based on the above specific embodiments, the panel includes fixed profiles and movable profiles. Two vertical fixed profiles 13 and two horizontal fixed profiles 16 form a frame. The two ends of the horizontal movable profile 14 are slidably connected to the two vertical fixed profiles 13. One end of the vertical movable profile 15 is slidably connected to the horizontal movable profile 14, and the other end is slidably connected to either the horizontal movable profile 14 or the horizontal fixed profile 16.

[0071] In one specific embodiment, two vertically fixed profiles serve as the main supporting structure for the panel. Two horizontally fixed profiles are connected to the vertical fixed profile 13, forming a stable rectangular frame. The fixed profiles provide basic support for the entire panel, ensuring the stability of the structure.

[0072] The horizontally movable profile 14 is slidably connected at both ends to the vertically fixed profile 13.

[0074] Based on the above specific embodiments, the horizontal movable profile 14 slides independently, and the vertical profiles connected between the horizontal movable profiles 14 are telescopic profiles.

[0075] In one specific embodiment, the horizontal movable profile 14 is slidably connected to the vertical fixed profile 13 at both ends, and slides independently in the vertical direction. A vertical movable profile 15 is connected between the horizontal movable profiles 14. The vertical movable profile 15 is a telescopic profile, comprising an inner sleeve and an outer sleeve respectively connected to the two horizontal profiles. It can extend and retract to adjust the distance between the horizontal movable profiles 14, avoiding interference from the fixed-length vertical profiles on the movement of the horizontal movable profiles 14. This allows for free and flexible adjustment of the component installation positions, meeting complex layout requirements and facilitating system expansion and upgrades.

[0076] Based on the above specific embodiments, a component is connected to multiple parallel synchronous profiles, and a group of synchronous profiles move synchronously.

[0077] In one specific embodiment, the component is fixed to two or more synchronously moving profiles by means of a sliding sleeve or connector, so as to fully position the component, prevent it from rotating during the movement, and ensure that the component remains stable during the movement.

[0078] Synchronous profiles can be connected by linkages, so that if one profile moves, the other profiles move synchronously. It should be noted that in this application, the movement of the movable profiles can be driven manually, or by a motor or telescopic rod to transmit power to the profiles, achieving synchronous movement.

[0079] Based on the above specific embodiments, the movable profile has sliders at both ends. The profile includes a back slide groove that mates with the sliders. The sliders are connected to and slidably connected to the back slide groove. The mating of the sliders and the back slide groove allows the movable profile to slide freely in the direction of the slide groove, thereby achieving profile position adjustment. The slider is usually fixed to the movable profile by screws or other fasteners. The slider can also be replaced by a pulley to reduce friction and ensure stability during sliding.

[0080] Based on the above specific embodiments, the front groove is provided on the front side of the profile, and the back groove is provided on the back side of the profile.

[0081] In one specific embodiment, the profile has grooves on both the front and back sides, or the front side of the profile is a sliding rod and the back side has grooves. The front groove is used to connect the connector of the component. The sliding sleeve cooperates with the sliding rod, or the connector cooperates with the groove through a slider, to achieve a sliding connection of the component. The back groove is used to connect the slider of the movable profile. The slider is inserted into the groove on the back side and slidably connected with the groove, thereby realizing the sliding of the movable profile.

[0082] The specific installation process for the movable profiles includes:

[0083] Insert the slider of the movable profile into the groove on the back of the profile.

[0084] Adjust the position of the movable profiles to meet the system layout requirements.

[0085] The movable profile is fixed to the profile by locking devices such as screws.

[0086] The component installation process includes:

[0087] Install the sliding sleeve onto the profile or insert the slider into the groove on the front of the profile.

[0088] Fix the components to the connecting part of the connector.

[0089] Adjust the position of the components to meet functional requirements.

[0090] The sliding sleeve or connector is fixed to the profile by a locking device.

[0091] The simultaneous connection of components and movable profiles is achieved through two sliding grooves on both sides of the profile, simplifying the installation process and reducing the number of connecting parts; the cooperation between the slider and the sliding groove reduces the installation difficulty and makes the connection convenient.

[0092] Based on the above specific embodiments, the slide is provided with a positioning groove in the length direction. The positioning groove is connected to the slide and is perpendicular to the slide. The slider is inserted into the positioning groove for positioning.

[0093] In one specific embodiment, a slide groove is provided along the length of the profile for mounting a slider, enabling a sliding connection of components or movable profiles. A positioning groove is perpendicularly connected to the slide groove and is used to fix the slider for rapid positioning. The positioning groove is typically designed in an L-shape or T-shape so that the slider can engage with the positioning groove after sliding to a designated position.

[0094] The slider is installed in a groove and can slide freely within it. When positioning is required, the slider engages in a positioning groove. The structure of the positioning groove restricts the movement of the slider, thereby achieving precise positioning.

[0095] Based on the aforementioned specific embodiments, the connector is provided with an elongated hole for floating connection with components. This design allows the components to float within a certain range, thus providing greater flexibility during installation and adjustment. Floating connection can reduce the impact of installation errors on system accuracy, while improving system stability and reliability.

[0096] Based on the above specific embodiments, the profile is provided with scale values, which are evenly distributed along the length of the profile. This is used to accurately measure and adjust the position of components or movable profiles, reducing human error and ensuring that the installation position of each component meets the design requirements.

[0097] The symmetrical scale values ​​of parallel profiles of the same length ensure rapid alignment and positioning during installation and adjustment, guaranteeing the system's symmetry and consistency. The intuitive scale values ​​allow operators to quickly locate the required installation position, simplifying the process and reducing adjustment time and errors. The precision of the scale values ​​improves the overall reliability of the system, reducing operational problems caused by installation errors.
