Description

Technical Field

[0001] This invention belongs to the field of mechanical processing and automation control technology, specifically a composite plate and strip size automatic adjustment device and its working method. Background Technology

[0002] With the widespread application of composite sheet and strip materials in the industrial field, the requirements for their dimensional accuracy and automatic adjustment capabilities are increasing. Although existing dimensional adjustment devices can meet production needs to a certain extent, they still have shortcomings in terms of automation, adjustment accuracy, and adaptability, making it difficult to fully meet the requirements of efficient and intelligent production.

[0003] A search revealed a size adjustment method and device, publication number CN115556023B, published on September 30, 2025. This patent achieves quantitative and multi-level size adjustment through the relative rotation of a first and second turntable, exhibiting high precision. However, this technical solution relies heavily on mechanical structure design and lacks automated control methods, resulting in high technical requirements for operators in practical applications and difficulty in achieving real-time dynamic adjustment. Furthermore, the device's applicability is relatively limited, making it difficult to flexibly adapt to the size adjustment needs of composite plates and strips of different materials and thicknesses.

[0004] A search revealed a patent with publication number CN112156451B, which discloses a handle and its size adjustment method, system, and device, published on July 22, 2022. This patent achieves personalized handle size adjustment by acquiring user hand feature point location data and combining it with an automated control system, improving operational comfort. However, this technical solution is designed for specific application scenarios (such as handles), and its adjustment logic and algorithm are difficult to directly apply to the size adjustment of composite sheet materials. Furthermore, the adjustment accuracy of this device is limited by the accuracy of sensor data and the complexity of the algorithm, and may not meet the requirements for high-precision processing of composite sheet materials.

[0005] The aforementioned problems indicate that existing size adjustment devices still have certain shortcomings in terms of automation control capabilities, adjustment accuracy, and adaptability to composite sheet and strip materials. Therefore, this invention provides an automatic size adjustment device for composite sheet and strip materials and its operating method. The aim is to improve the automation level and adjustment accuracy of the device by introducing intelligent control technology and optimizing the adjustment logic, while simultaneously enhancing its adaptability to composite sheet and strip materials of different materials and thicknesses, thereby meeting the demands of modern industry for efficient and intelligent production equipment. Summary of the Invention

[0006] The present invention addresses the problem of providing an automatic size adjustment device for composite strip materials and its operating method. It solves the technical problems of existing size adjustment devices that rely on mechanical structure design, which suffer from insufficient automated control, inadequate real-time dynamic adjustment capabilities, and limited adaptability to composite strip materials of different materials and thicknesses. Furthermore, to address the issue that the accuracy of sensor data and the complexity of algorithms may affect adjustment precision, the present invention improves adjustment precision and enhances adaptability by introducing an intelligent control system combined with optimized structural design.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An automatic size adjustment device for composite sheet strips includes a base, a sliding frame, adjustment modules, a drive unit, and sensing components. A sliding frame that slides along a guide rail is mounted on the top of the base, and the guide rail is fixed to the worktable of the processing equipment. Support beams are provided on both sides of the base, and the support beams are connected to the base by several reinforcing bolts. A linear guide rail is provided on the sliding frame, and several adjustment modules are slidably mounted on the linear guide rail. A clamping mechanism is installed at the bottom of each adjustment module. A hydraulic pipe seat is mounted on the base, and adjacent adjustment modules and adjustment modules are connected to the hydraulic pipe seat via flexible hydraulic pipes. The hydraulic pipe seat is connected to a hydraulic pump via a main hydraulic pipe. An adaptive adjustment mechanism is installed on each adjustment module.

[0008] The adjustment module has a cavity with hydraulic channels on both sides, and the hydraulic channels are connected to flexible hydraulic pipes.

[0009] The adaptive adjustment mechanism includes a sleeve mounted on top of the adjustment module, a piston assembly installed in the sleeve and cavity, the inner diameter of the sleeve being the same as the diameter of the cavity, a sealing ring being provided on the outer side of the piston assembly, and a return spring being installed at the bottom of the piston assembly and located in the cavity.

[0010] The sleeve has an air inlet, which is connected to an air pipe via an air nozzle. The air pipe is connected to an auxiliary hydraulic pipe. The piston assembly has an air groove at the bottom and an exhaust port communicating with the air groove on the side wall of the piston assembly.

[0011] An air pipe connector is installed on the base, and the auxiliary hydraulic pipe is connected to the air pipe connector. The air pipe connector is connected to the air source through the main air pipe.

[0012] The adjustment module is equipped with several rollers that are adapted to the linear guide rail. The adjustment module contains a first servo motor, and the output end of the first servo motor is connected to one of the rollers.

[0013] A second servo motor is installed at the end of the support beam. A guide groove is opened on the support beam, and a lead screw is installed at the output end of the second servo motor in the guide groove.

[0014] The lead screw is threadedly connected to the slider, and a bracket is installed on the slider. An electric push rod is installed on the bracket, and a pressure block is installed through the telescopic end of the electric push rod.

[0015] A method for operating an automatic size adjustment device for composite board strips, the specific operating steps of which are as follows: Step 1: The first servo motor drives the roller to rotate, which in turn moves the adjustment module on the sliding frame. According to the width distribution of the composite strip, the spacing of the adjustment modules is adjusted to adjust the spacing of the pressing mechanism. During the adjustment process, the interconnection between the adjustment modules is ensured by the flexible hydraulic pipe. Step 2: The hydraulic pump works to deliver hydraulic oil through the main hydraulic pipe and hydraulic pipe seat to the flexible hydraulic pipe, and then through the flexible hydraulic pipe to the cavity of the adjustment module. Pressure is applied by the clamping mechanism, and the device moves along the guide rail through the sliding frame to achieve the overall movement of the device. Step 3: The second servo motor drives the lead screw to rotate, which in turn moves the threaded slider along the support beam. After the initial adjustment of the module spacing, when the spacing is too large, the excess adjustment modules at the end of the support beam are idle. The slider moves to the first idle adjustment module, and the electric push rod moves the pressure block down to contact the piston assembly. The piston assembly moves down in the sleeve and cavity until the hydraulic channel is closed, completing the sealing of the clamping mechanism and the hydraulic channel. If the clamping mechanism malfunctions, the piston assembly moves down to align the exhaust port with the air inlet port, thus connecting the auxiliary hydraulic pipe to the cavity. The air source connects to the corresponding cavity through the main air pipe, air pipe connector, and auxiliary hydraulic pipe. The air source generates pulsed negative pressure in the cavity, drawing in abnormal impurities. These impurities then enter the air source through the auxiliary hydraulic pipe, air pipe connector, and main air pipe, and are filtered and discharged through the filter on the air source. When the pressure block moves up, the compressed return spring moves the piston assembly up to return to its original position, restoring the connection between the hydraulic channel and the cavity.

[0016] The beneficial effects of this invention are: by adopting a linear guide rail and adjustment module design, the rollers are driven by a first servo motor to realize flexible adjustment of the spacing of the pressing mechanism, adapting to composite strips with different width distributions; the sliding frame and base have a dual-movement design, which can move horizontally along the guide rail, while the pressing mechanism on the sliding frame can be longitudinally positioned to form a three-dimensional precise adjustment network. The electric push rod controls the pressing block piston assembly to block the hydraulic channel and connect the air passage, automatically starting the abnormal handling process without stopping the machine. It generates negative pressure through the air source to draw abnormal impurities from the pressing mechanism into the cavity and discharge them through the air pipe, automatically completing the abnormal handling and greatly improving work efficiency. The screw rotates, which in turn drives the threaded slider to move along the support beam to the idle adjustment module. The pressure block presses down to close the hydraulic channel, cutting off the hydraulic supply to the clamping mechanism and activating only the clamping mechanism that needs to be operated, thus reducing hydraulic energy consumption. Through four core innovations—dynamic adjustment, adaptive processing, energy-saving zoning, and intelligent control—it solves the pain points of traditional composite board and strip size adjustment devices, such as insufficient adaptability, low efficiency in handling abnormalities, high energy consumption, and reliance on manual labor.

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.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5The present invention provides an automatic adjustment device for the size of composite strip. Its specific implementation is as follows: A sliding frame 2 is installed on the top of a base 1. The sliding frame 2 is connected to the worktable of the processing equipment via a guide rail 6. The guide rail 6 is fixed on the worktable, and the sliding frame 2 can move horizontally along the guide rail 6. Support beams 7 are provided on both sides of the base 1. The support beams 7 are connected to the base 1 by several reinforcing bolts 8 to enhance the stability of the overall structure. A linear guide rail 9 is provided on the sliding frame 2. Several adjustment modules 3 are slidably installed on the linear guide rail 9. A pressing mechanism 10 is installed at the bottom of the adjustment modules 3 to apply pressure to the composite strip. A hydraulic pipe seat 11 is installed on the base 1. Adjacent adjustment modules 3 and adjustment modules 3 and hydraulic pipe seat 11 are connected by flexible hydraulic pipes 12. The flexible hydraulic pipes 12 have a certain degree of flexibility and can adapt to the movement of the adjustment modules 3 on the linear guide rail 9. The hydraulic pipe seat 11 is connected to a hydraulic pump 14 via a main hydraulic pipe 13. The hydraulic pump 14 provides hydraulic power to drive the pressing mechanism 10. An adaptive adjustment mechanism is installed on the adjustment modules 3 to achieve the blocking of hydraulic channels and the connection of air channels. The regulating module 3 has a cavity 16, with hydraulic channels 17 on both sides. The hydraulic channels 17 are connected to the flexible hydraulic pipe 12 to realize the flow of hydraulic oil. The adaptive regulating mechanism includes a sleeve 15 installed on the top of the regulating module 3. A piston assembly 18 is installed in the sleeve 15 and the cavity 16. The inner diameter of the sleeve 15 is the same as the diameter of the cavity 16. A sealing ring 19 is provided on the outside of the piston assembly 18 to ensure the sealing of the hydraulic channel 17 and prevent hydraulic oil leakage. A return spring 20 is installed at the bottom of the piston assembly 18 and inside the cavity 16. The return spring 20 is used to restore the piston assembly 18 to its original shape after being subjected to force. The sleeve 15 has an air inlet 21. The air inlet 21 is connected to the air pipe through an air nozzle. The air pipe is connected to the auxiliary hydraulic pipe 25. The bottom of the piston assembly 18 has an air groove 22. The side wall of the piston assembly 18 has an exhaust hole 23 that communicates with the air groove 22. The base 1 is equipped with an air pipe connector 24. The auxiliary hydraulic pipe 25 is connected to the air pipe connector 24. The air pipe connector 24 is connected to the air source 26 through the main air pipe. The air source 26 is used to provide gas power to generate negative pressure during abnormal handling. The adjustment module 3 is equipped with several rollers 27 adapted to the linear guide rail 9. The adjustment module 3 is equipped with a first servo motor 28. The output end of the first servo motor 28 is connected to one of the rollers 27. The first servo motor 28 drives the roller 27 to rotate, thereby moving the adjustment module 3 along the linear guide rail 9. The end of the support beam 7 is equipped with a second servo motor 29. The support beam 7 has a guide groove 30. The output end of the second servo motor 29 is located in the guide groove 30. A lead screw 31 is installed. The lead screw 31 is threadedly connected to the slider 32. A bracket 33 is installed on the slider 32. An electric push rod 34 is installed on the bracket 33. The telescopic end of the electric push rod 34 passes through the bracket 33. A pressure block 35 is installed on the pressure block 35. The pressure block 35 is used to press down the piston assembly 18 to achieve the blocking of the hydraulic channel 17 and the connection of the air channel. In actual operation, the first servo motor 28 drives the roller 27 to rotate, which in turn moves the adjustment module 3 on the sliding frame 2. The spacing of the adjustment modules 3 is adjusted according to the width distribution of the composite strip to adjust the spacing of the pressing mechanism 10. During the adjustment process, the flexible hydraulic pipe 12 ensures the interconnection between the adjustment modules 3 and ensures the uniform distribution of hydraulic oil. The hydraulic pump 14 works to deliver hydraulic oil through the main hydraulic pipe 13 and the hydraulic pipe seat 11 to the flexible hydraulic pipe 12, and then through the flexible hydraulic pipe 12 to the cavity 16 of the adjustment module 3. The hydraulic oil is pressurized by the pressing mechanism 10, and at the same time, the sliding frame 2 moves along the guide rail 6 to realize the overall movement of the device. The second servo motor 29 drives the lead screw 31 to rotate, which in turn drives the threaded slider 32 to move along the support beam 7. After the initial adjustment of the spacing of the adjustment modules 3, when the spacing of the adjustment modules 3 is too large, the excess adjustment modules 3 at the end of the support beam 7 are in an idle state. At this time, the slider 32 moves to the first idle adjustment module 3, and the electric push rod 34 drives the pressure block 35 to move down and contact the piston assembly 18. The piston assembly 18 moves down in the sleeve 15 and the cavity 16 until the hydraulic channel 17 is closed, completing the sealing of the clamping mechanism 10 and the hydraulic channel 17. When the clamping mechanism 10... When an abnormality occurs, the piston assembly 18 moves down to align the exhaust port 23 with the intake port 21. At this time, the auxiliary hydraulic pipe 25 is connected to the cavity 16. The air source 26 connects to the corresponding cavity 16 via the main air pipe, air pipe connector 24, and auxiliary hydraulic pipe 25. The air source 26 operates within the cavity 16, generating a pulsed negative pressure that draws abnormal impurities into the cavity 16. These impurities then enter the air source 26 via the auxiliary hydraulic pipe 25, air pipe connector 24, and main air pipe. They are then filtered and discharged through the filter installed on the air source 26. When the pressure block 35 moves up, the compressed return spring 20 drives the piston assembly 18 to move up, restoring its original position. The hydraulic channel 17 is then connected to the cavity 16 again. In the above embodiments, the first servo motor 28 drives the roller 27 through the linear guide rail 9 and the adjustment module 3 to achieve flexible adjustment of the spacing of the pressing mechanism 10 to adapt to different width distributions of composite strip materials. The sliding frame 2 and the base 1 have a dual-movement design that can move horizontally along the guide rail 6. At the same time, the pressing mechanism 10 on the sliding frame 2 can be longitudinally positioned to form a three-dimensional precise adjustment network. The electric push rod 34 controls the pressing block 35 to press down the piston assembly 18 to achieve the sealing of the hydraulic channel 17 and the connection of the air passage. The abnormal handling process is automatically started without machine shutdown. The negative pressure generated by the air source 26 draws abnormal impurities from the pressing mechanism 10 into the cavity 16 and discharges them through the air pipe, automatically completing the abnormal handling process. The rotation of the lead screw 31 drives the threaded slider 32 to move along the support beam 7 to the idle adjustment module 3. The pressure block 35 presses down to close the hydraulic channel 17, cutting off the hydraulic supply to the clamping mechanism 10. Only the clamping mechanism 10 that needs to be operated is activated, reducing hydraulic energy consumption. Through four core innovations—dynamic adjustment, adaptive processing, energy-saving zoning, and intelligent control—the invention solves the pain points of traditional composite board strip size adjustment devices, such as insufficient adaptability, low efficiency in abnormal handling, high energy consumption, and reliance on manual labor. In order to enable those skilled in the art to fully understand and implement the invention, the following supplementary explanation of the specific implementation principle of the invention is given in conjunction with a specific application scenario.

[0026] During the processing of composite strip, the composite strip to be processed is first placed on the worktable of the processing equipment, ensuring its initial alignment with the sliding frame 2. The first servo motor 28 is activated via the controller, driving the rollers 27 on the adjustment module 3 to rotate. The rollers 27 then move the adjustment module 3 along the linear guide rail 9. At this time, the spacing between the adjustment modules 3 is dynamically adjusted according to the actual width distribution of the composite strip to accommodate different width requirements. Throughout this process, the flexible hydraulic pipe 12 maintains hydraulic connectivity between adjacent adjustment modules 3, ensuring that hydraulic oil is evenly distributed in each cavity 16. The hydraulic pump 14 delivers hydraulic oil to the flexible hydraulic pipe 12 through the main hydraulic pipe 13 and hydraulic pipe seat 11. The hydraulic oil enters the cavity 16 of the adjustment module 3 through the flexible hydraulic pipe 12 and is pressured by the clamping mechanism 10, completing the initial fixing operation of the composite strip. Simultaneously, the sliding frame 2 moves horizontally along the guide rail 6 to achieve overall positioning of the device.

[0027] After the spacing of the adjustment modules 3 is adjusted, the second servo motor 29 starts, driving the lead screw 31 to rotate. The lead screw 31 drives the slider 32 to move along the support beam 7 via threaded transmission. During the initial adjustment process, if the spacing of the adjustment modules 3 is too large, the portion of the adjustment modules 3 located at the end of the support beam 7 will be idle. At this time, the slider 32 moves to the first idle adjustment module 3, and the electric push rod 34 drives the pressure block 35 to move down and contact the piston assembly 18. The pressure block 35 pushes the piston assembly 18 down within the sleeve 15 and cavity 16 until the piston assembly 18 completely closes the hydraulic channel 17, cutting off the hydraulic supply to the adjustment module 3. This process ensures that only the pressing mechanism 10 that needs to operate is activated, thereby reducing hydraulic energy consumption and improving work efficiency.

[0028] During processing, if the clamping mechanism 10 malfunctions, such as due to impurities clogging or hydraulic instability, the piston assembly 18 will move further downwards, aligning the exhaust port 23 with the air inlet port 21. At this time, the auxiliary hydraulic pipe 25 connects to the cavity 16, and the air source 26 injects gas into the cavity 16 through the main air pipe, air pipe connector 24, and auxiliary hydraulic pipe 25, generating a pulsed negative pressure. Under the negative pressure, abnormal impurities are drawn into the cavity 16 and discharged to the air source 26 through the auxiliary hydraulic pipe 25, air pipe connector 24, and main air pipe, where they are finally filtered by the filter installed on the air source 26. After the malfunction is resolved, the electric push rod 34 moves the pressure block 35 upwards, the return spring 20 pushes the piston assembly 18 back to its original position, the hydraulic channel 17 reconnects with the cavity 16, and the system returns to normal operation.

[0029] Furthermore, during the longitudinal positioning of the composite strip, the sliding frame 2 moves horizontally along the guide rail 6, forming a three-dimensional precision adjustment network in conjunction with the dynamic adjustment of the adjustment module 3. Through the coordinated work of the first servo motor 28 and the second servo motor 29, the adjustment module 3 can flexibly adapt to composite strips of different materials and thicknesses, significantly improving the adaptability of the device. At the same time, the operation of the electric push rod 34 controlling the pressure block 35 to press down the piston assembly 18 realizes the sealing of the hydraulic channel 17 and the connection of the air channel, automatically initiating the abnormal handling process, and completing the removal of abnormal impurities without manual intervention, greatly improving work efficiency.

[0030] In the above embodiments, through four core innovations—dynamic adjustment, adaptive processing, energy-saving zoning, and intelligent control—the shortcomings of traditional composite sheet and strip size adjustment devices in terms of adaptability, anomaly handling efficiency, energy consumption, and reliance on manual labor are solved. The technical solution of this invention not only meets the demands of modern industry for efficient and intelligent production equipment but also provides more reliable technical support for the field of composite sheet and strip processing.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
