Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering and automation control technology, specifically to a light-blocking PE film fixing device with heat preservation function. Background Technology

[0002] In industrial production, agricultural planting, and packaging and storage, PE film is widely used in scenarios such as shading and heat preservation due to its good flexibility, weather resistance and cost advantages.

[0003] Currently, when PE films expand and contract due to temperature changes, the fixing devices cannot adjust the clamping force in time, which can lead to the film becoming loose or tearing due to excessive tightness, thereby damaging the integrity of the insulation layer. In addition, some fixing devices lack the ability to monitor and automatically adjust key parameters such as ambient temperature and film tension in real time, and cannot dynamically optimize the fixing state according to actual working conditions, thus limiting the stability and accuracy of the insulation function. Existing technologies have not organically combined the optimization of insulation performance with mechanical structure and control system, making it difficult to meet the needs of high-precision insulation scenarios, and therefore there is room for improvement. Utility Model Content

[0004] To address the problems mentioned in the background section, a light-blocking PE film fixing device with heat insulation function is proposed. The technical solution adopted by this utility model is as follows:

[0005] A light-blocking PE film fixing device with heat insulation function includes a main frame, an elastic gripper, and an adjustment system. The main frame adopts a nested structure, comprising a base frame and a telescopic frame from the inside out. The base frame and the telescopic frame are connected by a linear guide slider mechanism. The base frame is welded into a rectangle and fixed to a production line bracket with bolts. The two sides of the base frame are connected to the gripper bracket via hinges. The elastic gripper includes a gripper base and a gripper body. The gripper body is hinged to the gripper base via a hinge shaft. The gripper base is connected to the gripper bracket via a universal joint. The adjustment system includes a mechanical adjustment structure, an electrical control system, and a human-machine interface. The mechanical adjustment structure is used for... The current fixing device allows for adjustment of position, angle, and clamping force. The mechanical adjustment structure includes X-axis, Y-axis, and Z-axis adjustment components. The X-axis adjustment component adjusts the lateral spacing of the grippers, the Y-axis adjustment component adjusts the telescopic length of the frame, and the Z-axis adjustment component adjusts the height of the pressure plate. The electrical control system includes a sensor network, a PLC controller, and a drive module. The sensor network collects clamping force, displacement, and PE film tension parameters in real time. The PLC controller uses model prediction based on the sensor data to control the drive module to drive the mechanical adjustment structure. The human-machine interface includes a touchscreen for preset adjustment parameters and manual fine-tuning.

[0006] By adopting the above technical solution, in the nested main frame, the reference frame and the telescopic frame are connected by a linear guide slider mechanism to ensure structural stability. The telescopic length of the frame can be flexibly controlled by the Y-axis adjustment component, which can adapt to the production needs of PE film of different specifications. When not in use, it reduces the space occupied and improves the space utilization of the production line. The hinge connection between the gripper bracket and the reference frame, together with the hinge shaft and universal joint design of the elastic gripper, enables the elastic gripper to have multi-angle adjustment capability. It can not only fit tightly against the surface of the heat insulation and light-blocking PE film, but also accurately control the height of the film pressing plate through the Z-axis adjustment component, ensuring that the heat insulation and light-blocking PE film is flat and wrinkle-free when fixed, thus improving the product forming quality.

[0007] The collaborative operation of the mechanical adjustment structure, electrical control system, and human-machine interface constructs an intelligent control system. The mechanical adjustment components enable precise adjustment of position, angle, and clamping force, while the X-axis adjustment components flexibly adjust the lateral spacing of the grippers to adapt to PE films of different widths. In the electrical control system, a sensor network monitors clamping force, displacement, and film tension in real time. The PLC controller uses model prediction to drive the mechanical structure, forming a closed-loop feedback control to avoid damage or insecure fixation due to uneven stress on the film material. The human-machine interface balances convenience and accuracy, with preset parameters and manual fine-tuning functions on the touchscreen to meet standardized production requirements and allow operators to flexibly adjust according to actual working conditions. This significantly improves equipment applicability and production efficiency, reduces manual intervention costs, and provides comprehensive technical support for the stable and efficient production of heat-insulating and light-shielding PE films.

[0008] Optionally, the guide rail slider mechanism of the reference frame and the telescopic frame is a linear guide rail slider to ensure the accuracy of the telescopic movement.

[0009] By adopting the above technical solution, the linear guide slider has extremely high guiding accuracy, which can ensure that the telescopic frame remains stable during movement and avoid deviation, shaking and other situations. It can accurately control the displacement of the telescopic frame, so that the fixing device can precisely adjust the overall length according to the production needs of different specifications of heat insulation and light-blocking PE film, effectively adapt to diverse production scenarios, and improve the versatility of the equipment.

[0010] Optionally, a butterfly spring is installed inside the gripper base, and the clamping force is adjusted by the compression of the butterfly spring.

[0011] By adopting the above technical solution, the butterfly spring has unique mechanical properties, which can provide a large amount of elastic deformation and stable clamping force in a limited space. When the gripper contacts the heat-insulating and light-blocking PE film, the spring is compressed. By controlling the amount of compression, the pressure of the gripper on the heat-insulating and light-blocking PE film can be precisely adjusted to ensure that the heat-insulating and light-blocking PE film is firmly fixed, avoiding problems such as displacement and slippage during the production process. It can also prevent excessive pressure from damaging the surface of the film material, thus ensuring the integrity and quality of the heat-insulating and light-blocking PE film.

[0012] Optionally, the clamping surface of the gripper body is provided with an anti-slip silicone layer to enhance the fixing effect on the PE film.

[0013] By adopting the above technical solution, the clamping surface of the gripper body is provided with an anti-slip silicone layer. The silicone itself is soft and highly elastic, which can closely adhere to the surface of the heat-insulating and light-blocking PE film. Even if there are slight unevennesses on the surface of the film, the silicone layer can also adaptively fill the gaps, increase the contact area, and improve the friction between the gripper and the heat-insulating and light-blocking PE film. The anti-slip properties of the silicone effectively prevent the gripper from sliding or misaligning during the fixing of the heat-insulating and light-blocking PE film, ensuring the stability of the film material during production and processing, and avoiding quality problems such as wrinkles and damage caused by displacement. The anti-slip silicone layer also has good chemical stability and weather resistance, and is not prone to chemical reaction with the heat-insulating and light-blocking PE film, so it will not affect the heat-insulating and light-blocking properties of the film material.

[0014] Optionally, the drive module includes a servo motor drive component, which is connected to the X-axis, Y-axis and Z-axis adjustment components.

[0015] By adopting the above technical solution, the drive module uses a servo motor drive component connected to the X, Y, and Z axis adjustment components. The servo motor has high-precision position and speed control capabilities, and can precisely drive the operation of each axis adjustment component according to the instructions of the electrical control system. This enables fine adjustments to the lateral spacing of the grippers, the extension and retraction length of the frame, and the height of the pressure plate, ensuring that the heat-insulating and light-blocking PE film is in a precise position during the fixing process. This meets the installation requirements of different specifications of film materials. The data feedback from the servo motor and the sensor network work together to monitor the adjustment status in real time and correct errors, ensuring the accuracy and stability of each axis adjustment. The servo motor drive component has high reliability and long service life, reducing the equipment failure rate and maintenance costs. This ensures the long-term stable operation of the heat-insulating and light-blocking PE film fixing device, providing a solid power guarantee for the continuous and high-precision production of heat-insulating and light-blocking PE film.

[0016] Optionally, the sensor network includes a pressure sensor, a displacement sensor, and a tension sensor, which respectively collect clamping force, frame expansion and contraction displacement, and PE film tension data.

[0017] By adopting the above technical solutions, the sensor network integrates pressure, displacement, and tension sensors to construct a comprehensive data monitoring system. This provides core support for the precise operation of the thermal insulation and light-blocking PE film fixing device. The pressure sensor captures the clamping force data of the gripper in real time, avoiding damage to the thermal insulation and light-blocking PE film due to excessive pressure or fixing failure due to insufficient pressure. This ensures that the film material is always under safe and stable stress during the production process. The displacement sensor accurately monitors the expansion and contraction displacement of the frame, ensuring that the device can flexibly adapt to the production needs of thermal insulation and light-blocking PE films of different specifications, achieving rapid and accurate size adjustment. The tension sensor provides real-time feedback on the tension status of the thermal insulation and light-blocking PE film. If abnormal tension fluctuations occur, the data can be transmitted to the PLC controller in a timely manner. Combined with preset parameters, an alarm or automatic adjustment mechanism is triggered to prevent problems such as wrinkles and breakage of the film material due to uneven tension. The three types of sensors work together to form a complete data closed loop. Based on this real-time data, the PLC controller uses model prediction to drive the servo motor and other actuators to perform precise actions, achieving dynamic optimization of the fixing device's position, angle, and clamping force. This significantly improves the equipment's intelligence level and production stability, and increases production efficiency and product quality.

[0018] Optionally, the electrical control system further includes an alarm module, which determines whether parameters collected by the sensor network exceed a preset threshold and issues an audible and visual alarm.

[0019] By adopting the above technical solution, the electrical control system is equipped with an alarm module that performs threshold judgment and audible and visual alarms based on sensor network data. Parameters collected in real time by sensors such as pressure, displacement, and tension are analyzed and compared by the alarm module. When situations such as excessive clamping force that may damage the membrane material, excessive frame expansion and contraction displacement leading to abnormal device operation, or tension imbalance of the heat-insulating and light-shielding PE film that is on the verge of breakage occur, the alarm module will immediately trigger an audible and visual alarm. The alarm module can also record the specific parameters at the time of the alarm to provide accurate data support for fault diagnosis and equipment maintenance, helping technicians to quickly locate the root cause of the problem and reduce downtime for maintenance.

[0020] Optionally, the human-computer interaction adjustment interface also includes a physical adjustment knob, which is electrically connected to the X-axis, Y-axis, and Z-axis adjustment components and the angle adjustment structure to achieve quick parameter adjustment.

[0021] By adopting the above technical solution, the human-machine interface electrically connects the physical adjustment knobs with the X, Y, and Z axes and angle adjustment structure, bringing an intuitive and efficient operating experience to the thermal insulation and light-blocking PE film fixing device. Operators do not need complex programming or multi-level menu operations; they can quickly adjust the lateral spacing of the grippers, the extension length of the frame, the height of the pressure plate, and the gripper angle by simply rotating the physical adjustment knobs. This significantly shortens the parameter setting time and improves production preparation efficiency. When dealing with the production needs of thermal insulation and light-blocking PE films of different specifications, the instant feedback characteristic of the knob adjustment allows operators to quickly observe changes in equipment operation and make timely fine adjustments to the ideal state, avoiding film material fixing deviations due to improper parameter settings.

[0022] The beneficial effects of this utility model's light-blocking PE film fixing device with heat preservation function are as follows:

[0023] 1. Through the nested main frame design, the base frame and the telescopic frame are connected by a linear guide slider mechanism, which ensures the stability of the structure. The Y-axis adjustment component can flexibly control the telescopic length of the frame to adapt to the production needs of different specifications of heat-insulating and light-blocking PE film. When not in use, it reduces the space occupied and effectively improves the space utilization rate of the production line.

[0024] 2. The elastic gripper is connected to the gripper bracket via a hinge shaft and universal joint. With the Z-axis adjustment component, it can precisely control the height of the pressure plate, enabling the gripper to have multi-angle adjustment capability. It can closely fit the surface of the heat insulation and light-blocking PE film, ensuring that the heat insulation and light-blocking PE film is flat and wrinkle-free when fixed.

[0025] 3. The closed-loop control system, consisting of a sensor network, PLC controller, and servo motor drive components, can collect clamping force, displacement, and membrane tension data in real time and drive the dynamic adjustment of the mechanical structure through model prediction. This avoids problems such as membrane material breakage or insecure fixation due to uneven force, greatly improving the stability and reliability of equipment operation.

[0026] 4. By combining the touch screen preset parameters and manual fine-tuning function with the quick operation of physical adjustment knobs in the human-machine interface, the system meets the needs of standardized production. Operators can flexibly adjust the system according to the actual working conditions, which greatly improves the applicability and production efficiency of the equipment while reducing the cost of manual intervention, thus achieving an organic unity of intelligence and humanization.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a light-blocking PE film fixing device with heat preservation function.

[0034] Reference Figure 1 In practical applications, the fixing device uses a reference frame 11 bolted to the production line support. The linear guide rail slider 2 mechanism between the reference frame 11 and the telescopic frame 12 ensures high precision in telescopic movement. When it is necessary to fix different specifications of heat-insulating and light-blocking PE film 6, the operator inputs the film material parameters on the touch screen 530 of the human-machine interface 53. The system drives the mechanical adjustment structure 51 to move: the X-axis adjustment component 510 adjusts the lateral spacing of the gripper, the Y-axis adjustment component 511 controls the telescopic frame 12 to extend and retract along the guide rail slider to match the length of the film material, and the Z-axis adjustment component precisely controls the height of the pressure plate. The elastic gripper 4 is hinged to the reference frame 11 through the gripper bracket 3. The gripper body 42 is connected to the gripper base 41 through the hinge shaft. With the help of the universal joint, multi-angle adjustment is achieved to ensure that the gripper surface is tightly attached to the surface of the heat-insulating and light-blocking PE film 6. The butterfly spring in the gripper base 41 automatically adjusts the compression amount according to the thickness of the film material to maintain the clamping force within a reasonable range. The anti-slip silicone layer on the gripping surface of the gripper body 42 enhances the friction and prevents the film from sliding.

[0035] During operation, pressure sensor 525, displacement sensor 526, and tension sensor 527 collect data in real time and transmit it to PLC controller 521. PLC controller 521 uses model prediction to drive servo motors to dynamically adjust the position of each axis. When the heat-insulating and light-shielding PE film 6 expands and contracts due to temperature changes, sensor network 520 monitors tension changes in real time. The system automatically adjusts the frame extension length and clamping force to prevent the film from tearing due to excessive tightness or loosening and displacement. If the parameters exceed the preset threshold, alarm module 523 immediately issues an audible and visual alarm. Operators can quickly and finely adjust parameters such as gripping angle and pressure plate height using physical adjustment knob 531 to ensure that the PE film remains flat during the fixing process, achieving efficient and precise production operations.

[0036] Reference Figure 2 The nested structure of the main frame 1 is the core foundation for the device to achieve adaptive adjustment. The reference frame 11 is welded into a rectangle and fixed to the production line support with bolts. The two sides are connected to the gripper support 3 through hinges. The external telescopic frame 12 is connected to the reference frame 11 through the linear guide slider 2. When it is necessary to adapt to different lengths of heat-insulating and light-blocking PE film 6, the Y-axis adjustment component 511 drives the telescopic frame 12 to slide smoothly along the linear guide slider 2. When the length of the heat-insulating and light-blocking PE film 6 is adjusted from 20 meters to 30 meters, the operator sends a command through the touch screen 530. The servo motor drives the Y-axis adjustment component 511 to make the telescopic frame 12 complete the extension of 10 meters. The displacement sensor 526 monitors the extension and retraction in real time and feeds back to the PLC controller 521 to ensure that the frame length accurately matches the film size. This nested frame design allows the device to meet the fixing requirements of different specifications of film while ensuring that the heat-insulating and light-blocking PE film 6 always remains flat and wrinkle-free.

[0037] Reference Figure 3 The adjustment system 5, which is composed of a mechanical adjustment structure 51, an electrical control system 52, and a human-machine interface 53, is the core module for the device to achieve intelligent control. The X-axis, Y-axis, and Z-axis adjustment components in the mechanical adjustment structure 51 are connected to the servo motor drive component 524. When the operator inputs the specifications of the heat-insulating and light-shielding PE film 6 into the human-machine interface 53, the PLC controller 521 generates adjustment commands based on the data collected by the sensor network 520 and through model prediction.

[0038] The sensor network 520 of the electrical control system 52 continuously collects key parameters: the pressure sensor 525 monitors the clamping force of the gripper on the membrane material in real time. When the thickness of the heat-insulating and light-shielding PE film 6 is 0.2mm, the system automatically maintains the clamping force at about 40N. The tension sensor 527 is installed on the membrane material conveying path. When the tension fluctuation exceeds ±15%, the PLC controller 521 immediately instructs the Y-axis adjustment component 511 to extend the frame and simultaneously fine-tune the height of the Z-axis pressure plate. The alarm module 523 performs threshold judgment on the sensor data. When the clamping force or tension exceeds the set threshold, it immediately triggers an audible and visual alarm and displays the fault location on the touch screen 530, pausing the equipment operation to protect the membrane material.

[0039] The human-machine interface 53 combines automation and flexibility. The touch screen 530 can preset commonly used membrane material parameters. After clicking the corresponding mode, the system will automatically complete the adjustment. The physical adjustment knob 531 is used for real-time fine adjustment. When the operator rotates the knob, the gripper base 41 rotates synchronously through the universal joint and adjusts in conjunction with the hinge shaft to ensure that the gripper surface is completely attached to the membrane material surface. This intelligent control system enables the device to maintain a stable fixing effect under complex working conditions.

[0040] Reference Figure 4The workflow of the adjustment system 5 constitutes the core logic of the intelligent operation of the device. When the device is started, the pressure sensor 525, displacement sensor 526, and tension sensor 527 in the sensor network 520 simultaneously begin data acquisition, monitoring the clamping force of the gripper, the telescopic displacement of the frame, and the tension state of the heat-insulating and light-shielding PE film 6 in real time. During the fixing process of the heat-insulating and light-shielding PE film 6, the tension sensor 527 continuously feeds back the tension value of the film on the conveying path. If the heat-insulating and light-shielding PE film 6 expands due to the increase in ambient temperature, the tension value will gradually decrease from the initial value. The tension sensor 527 transmits the data to the PLC controller 521. The PLC controller 521 predicts and calculates the distance that the frame needs to be extended through a preset model and sends a command to the drive module 522. After receiving the command, the servo motor drive component 524 in the drive module 522 immediately drives the mechanical adjustment mechanism. The Y-axis adjustment component 511 of the mechanical adjustment mechanism slowly extends the telescopic frame 12 along the linear guide slider 2, and the Z-axis adjustment component finely adjusts the height of the pressure plate to adapt to the change of the film. At the same time, the displacement... Sensor 526 monitors the frame's expansion and contraction in real time. When the calculated elongation reaches a certain value, it sends feedback to PLC controller 521. PLC controller 521 then instructs the servo motor to stop, ensuring that the tension of the thermal insulation and light-blocking PE film 6 remains within a safe range. If the parameters collected by the sensor exceed the preset threshold, alarm module 523 will immediately trigger an audible and visual alarm. If pressure sensor 525 detects that the clamping force of a certain gripper reaches 60N, while the safety threshold is 50N, alarm module 523 will issue an alarm and highlight the position of the gripper on the touchscreen 530 of the human-machine interface 53, automatically pausing the mechanical adjustment structure 51 to prevent the thermal insulation and light-blocking PE film 6 from breaking due to excessive force. Operators can view real-time data through touchscreen 530 and manually adjust the gripper angle and pressure plate height using physical adjustment knob 531. The device can be restarted after the parameters return to normal, ensuring that the thermal insulation and light-blocking PE film 6 maintains a stable fixation effect during production or installation, effectively improving the automation level and reliability of the equipment.

[0041] The implementation principle of a light-blocking PE film fixing device with heat insulation function in this application embodiment is as follows:

[0042] When the fixing device is used, the heat-insulating and light-shielding PE film 6 is dynamically and accurately fixed. The main frame 1 of the device adopts a nested structure. The reference frame 11 and the telescopic frame 12 are connected by a linear guide rail slider 2 to ensure the stability of the device structure. The telescopic frame 12 is driven to slide along the guide rail by the Y-axis adjustment component 511. The operator adjusts the overall size of the frame according to the length specification of the PE film to avoid the film from tearing due to excessive tension. During this process, the displacement sensor 526 will monitor the telescopic displacement of the frame in real time and feed it back to the PLC controller 521 to ensure the adjustment accuracy.

[0043] The elastic gripper 4 is connected to the gripper bracket 3 via a hinge shaft and a universal joint, enabling the elastic gripper 4 to have multi-angle adjustment capabilities. It can closely fit different curvatures or uneven areas on the surface of the heat-insulating and light-shielding PE film 6. The butterfly spring in the gripper base 41 automatically adjusts the compression amount according to the film thickness, thereby controlling the magnitude of the clamping force. The anti-slip silicone layer on the clamping surface of the gripper body 42 increases the friction and prevents the film from sliding during the fixing process, further improving the fixing effect.

[0044] The operation of the adjustment system 5 is based on a closed-loop control system consisting of sensor network 520, PLC controller 521 and drive module 522. When the device is started, pressure sensor 525, displacement sensor 526 and tension sensor 527 will synchronously collect data on clamping force, frame telescopic displacement and PE film tension and transmit these parameters to PLC controller 521 in real time. The preset model prediction in PLC controller 521 will calculate the optimal action parameters of each adjustment component based on historical data and current working conditions.

[0045] During the adjustment and execution phase, the servo motor drive component 524 in the drive module 522 precisely controls the X-axis, Y-axis, and Z-axis adjustment components according to the instructions of the PLC controller 521. When the Y-axis adjustment component 511 adjusts the extension and retraction length of the frame, the servo motor drives the extension frame 12 to slowly extend along the linear guide slider 2. The displacement sensor 526 provides real-time feedback on the displacement with a sampling accuracy of 0.1 mm. When the calculated value is reached, a stop signal is immediately sent to the controller to ensure that the adjustment error does not exceed ±0.3 mm. If a parameter exceeds the safety threshold during the debugging process, the alarm module 523 will simultaneously trigger an audible and visual alarm and highlight the abnormal gripper position on the touch screen 530. The operator can manually fine-tune the gripper angle or the pressure plate height through the physical adjustment knob 531. This debugging mechanism, which integrates real-time data acquisition, intelligent algorithm decision-making, precise execution adjustment, and human-machine collaborative intervention, ensures that the device always keeps the fixed error within a very small range under complex working conditions such as thermal expansion and contraction and thickness changes of the PE film, thus ensuring the stability of the heat preservation and light-shielding performance.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
