Description
Technical Field
[0001] The present invention relates to the technical field of roller adjustment devices, and in particular to a roller adjustment device for a tension-stabilized film laminating machine and a real-time monitoring method for web tension. Background Art
[0002] In modern industrial fields such as electronics, automobiles, and packaging, film laminating machines are becoming increasingly popular as key equipment for achieving product surface protection, decoration, and functionalization. During the film laminating process, the roller adjustment device directly affects the quality and efficiency of the film laminating. Stable tension control ensures that the film material is flat and wrinkle-free on the product surface, avoiding defects such as bubbles and offset, which is crucial to improving product quality and production efficiency.
[0003] However, during use, the existing roller adjustment devices of film laminating machines mostly rely on manual experience to adjust the roller pressure, making it difficult to dynamically adjust the tension in real time according to the film material characteristics and film laminating speed. This can easily lead to problems such as the film being too tight and deforming, or being too loose and wrinkling, affecting the film laminating effect and product qualification rate. Secondly, the pressure monitoring function is missing. Most devices lack an effective pressure detection mechanism, making it impossible to obtain pressure data between the roller and the film material in a timely manner, making it difficult to accurately analyze and control the tension changes during the film laminating process.
[0004] Traditional laminating machines often use fixed mechanical structures for roller adjustment, which cannot dynamically adjust sensitivity according to the film type. This results in highly elastic films being prone to stretching and deformation due to adjustment lag during high-speed lamination. In contrast, overly sensitive adjustment can lead to increased mechanical loss for thick, low-elastic films.
[0005] Therefore, the above technical problems need to be solved. Summary of the Invention

Mounting slots are provided on three sides of the sliding hole. An extrusion block is installed inside the mounting slot through an adjusting push rod.

If the push rod is extended by 1mm and the rubber pad is compressed by 0.8mm, then ); The elasticity of the rubber pad conforms to Hooke's law , is the elastic coefficient of the rubber pad (the measured Shore hardness of the rubber pad is 60A, );
[0048] The sensitivity of the fixed plate 4 can be understood as the response speed / displacement response of the fixed plate 4 to the change of tension. In essence, the friction force acts as a "resistance" to affect the dynamic characteristics of the fixed plate movement; the driving force generated by the tension change of the fixed plate 4 When moving, friction must be overcome ,Right now , is the equivalent mass data of the fixed plate 4 and the associated moving parts, is acceleration; sensitivity It can be defined as "the response acceleration of the fixed plate 4 under unit tension change", tension The amount of change Directly drive the fixed plate 4 to move, then , derive , that is, sensitivity , The proportional coefficient is obtained by adjusting the length of the push rod and the sensitivity change data of the fixed plate 4 during the adjustment process.

[0050] formula It is derived based on the mechanical model of the wrap angle of the coil to the extrusion roller. When the angle wraps around the extrusion roller, according to the principle of force balance, the component of force perpendicular to the axis of the roller is , which is equal to the pressure detected by the pressure sensor , so ; When the corner hour, , the formula is simplified to (in The equivalent contact diameter of the coil, approximately equal to the coil thickness ); For example, pressure is detected , extrusion roller diameter , coil thickness , then the tension ; In practical applications, the wrap angle It needs to be detected in real time by visual sensors. When there is a change (such as the film material deviates and causes the wrap angle to decrease), the system automatically corrects the calculation coefficient to ensure that the tension calculation error is ≤1%;
[0051] The value is set according to the film material precision requirement, such as high requirements for optical film, , that is, when Not present When abnormality is determined; For example, the allowed range is 48.5-51.5N, and an alarm will be triggered if it exceeds this range; Used to determine the deviation between the calculated value and the independent tension sensor (such as laser tension meter). , indicating the presence of mechanical interference (such as roller eccentricity) or calculation model errors; for example, , then the deviation threshold is 4N, if , , it is determined to be interference from external factors, and the influence of eccentricity or temperature and humidity needs to be checked;

[0053] After receiving the adjustment signal, the execution module obtains the corresponding adjustment strategy from the preset film material parameter database based on the coil material information input by the staff at the control box position, and adjusts the corresponding adjustment sensitivity according to the adjustment strategy;
[0054] The pressure data at the time when the tension was abnormal Record, if every time period Post-pressure data If the fluctuation occurs again, it is determined to be periodic. Calculate; obtain the speed data of the extrusion roller 12 , the rotation frequency of the extrusion roller 12 is ,like , it is determined that the tension detection is abnormal due to the eccentricity of the extrusion roller 12, an eccentricity warning signal is generated, and the eccentricity warning signal is transmitted to the execution module;

At this time, the radial runout of the roller is usually greater than 0.1mm and needs to be repaired;
[0056] After receiving the eccentricity warning signal, the execution module sends a buzzer warning through the buzzer module of the intelligent control component, and controls the yellow light of the three-color indicator light set on the outside of the control box to light up, informing the maintenance personnel that the abnormal tension warning is caused by the eccentricity of the extrusion roller 12;
[0057] If the extrusion roller 12 is not eccentric and the abnormal tension fluctuation is non-periodic, the temperature and humidity data of the surrounding environment within a set time period before and after the fluctuation moment are obtained, the ambient temperature and humidity data within the set time period are sorted according to the acquisition time, the difference between the temperature and humidity data of adjacent acquisition times is calculated, and the temperature and humidity change amount is calculated based on the difference. If the temperature and humidity change amount corresponding to the fluctuation moment exceeds the preset fluctuation threshold, it is determined that the tension detection abnormality is caused by the change in ambient temperature and humidity, and a temperature and humidity warning signal is generated and transmitted to the execution module;
[0058] Obtain temperature and humidity data 30 minutes before and after the abnormal moment, sort by time, and calculate the change of adjacent points 、 ; The preset threshold is or For example, the temperature rises suddenly from 25℃ to 28℃ ( ), triggering temperature and humidity compensation, the system automatically Correct the tension target value (0.02 is the temperature compensation coefficient, and the elastic modulus decreases by 2% for every 1°C increase in the measured PET film temperature);
[0059] After receiving the temperature and humidity warning signal, the execution module sends a buzzer warning through the buzzer module of the intelligent control component and controls the green light of the three-color indicator light set on the outside of the control box to light up, informing the maintenance personnel that the abnormal tension warning is caused by changes in ambient temperature and humidity;
[0060] If there is no abnormality in temperature and humidity, a warning signal is generated and transmitted to the execution module; after receiving the warning signal, the execution module sends a buzzer warning through the buzzer module of the intelligent control component, and controls the red light of the three-color indicator light set on the outside of the control box to light up, informing the maintenance personnel that the abnormal tension warning is not caused by eccentricity and changes in ambient temperature and humidity.
[0061] Working principle: When the present invention is used, the roller adjustment device first constructs a stable support frame through two guide plates 1 and a top plate 8 vertically arranged on the ground, and then fixes it horizontally through the support plate 2 between the guide plates 1 to provide a rotating installation basis for the support roller 3, and then rotates the fixing rod to fix it in the threaded hole 13. At this moment, the extrusion roller 12 is put on the outside, and then the movable plate 5 is moved by the second electric telescopic rod 10 to fix the extrusion roller 12. At this time, the film material passes through the gap between the support roller 3 and the extrusion roller 12. When the tension is too large, the fixed plate 4 will be lifted upward, so that the sensing end of the pressure sensor 7 on the lifting plate 11 detects the pressure data in real time, and feeds back the data, thereby controlling the first electric telescopic rod 9 to drive the lifting plate 11 to move up and down, and then adjust the height of the fixed plate 4 and the support roller 3, so that the film tension is kept within a stable range to ensure the quality of the film.
