[0035] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0036] The floating roller weighing device measures the real-time weight of the floating roller and displays it on the display screen. This device uses a hydraulic cylinder to extend and retract a telescopic rod, which in turn moves the weight hammer back and forth, adjusting the weight. Based on the lever principle, the length of the telescopic rod's extension and retraction balances the weight of the floating roller. A desired weight range is set; if the weight is within this range, no adjustment is needed. If it exceeds this range, it indicates that the floating roller is applying excessive pressure to the component, requiring a weight balancing process. The PLC controls the hydraulic cylinder to extend and retract the telescopic rod, with adjustable steps for each extension and retraction until the excess weight is balanced and the desired weight range is reached. If the measured weight of the floating roller exceeds the set range, the hydraulic cylinder extends the telescopic rod, causing the weight hammer to extend as well, balancing the excess weight until the weight reaches the desired range. If the weight is below this range, adjust accordingly. The hydraulic cylinder will retract the telescopic rod, and the weight hammer will also retract to neutralize the weight of the floating rod when it is below this range, until the weight of the floating rod reaches the required setting range.

[0037] This invention realizes the automatic adjustment process of the floating roller weight. The adjustment mechanism is complete and the adjustment method is novel. The PLC control adjustment has a high degree of automation and high adjustment accuracy, which is of great significance in actual production.

[0056] Preferably, the floating rod weight balance self-adjusting device is installed between the first conveying device 9 and the second conveying device 10. The first conveying device 9 includes a mounting bracket 91, in which a conveying group 15 is installed. The first bracket 11 is fixedly connected to the output side of the mounting bracket 91, and the support frame 4 is fixedly connected to the output side of the mounting bracket 91.

[0057] Preferably, the support frame 4 is located above the first connecting mechanism.

[0058] Preferably, the first connecting mechanism includes:

[0059] The first connecting block 13 is fixedly connected to the output side of the horizontal shaft 12, and a floating rod 1 is connected to the first connecting block 13.

[0060] Preferably, the counterweight structure includes:

[0061] Hydraulic cylinder 6, which is fixedly connected to horizontal shaft 12;

[0062] Telescopic rod 7, which is connected to hydraulic cylinder 6, and floating rod 1 and telescopic rod 7 are located on opposite sides of the axial direction of horizontal axis 12;

[0063] The weight hammer 8 is fixedly connected to the telescopic end of the telescopic rod 7.

[0064] Preferably, the conveying direction of the first conveying device 9 and the second conveying device 10 is both the front-to-back direction, the first support 11 consists of two sets spaced apart from left to right, the horizontal shaft 12 is rotatably connected to the two sets of first support 11, and the first connecting block 13 consists of two sets spaced apart from left to right.

[0065] Preferably, both sets of first connecting blocks 13 are provided with a plurality of connecting holes 14, the connecting holes 14 of the two sets of first connecting blocks 13 are opposite to each other, and the two ends of the floating rod 1 are respectively connected to the opposite connecting holes 14.

[0066] Preferably, the mounting bracket 91 includes: an upper frame 911, support legs 912, and connecting brackets 913. A plurality of support legs 912 are fixedly arranged at intervals at the lower end of the upper frame 911. The conveying group 15 is connected to the upper frame 911, and the connecting brackets 913 are fixedly connected between the support legs 912.

[0067] During the actual production process of the semi-finished parts, the floating roller 1 is used for weight adjustment. However, the floating roller 1 itself has gravity, which exerts a certain downward pressure on the semi-finished parts and causes a certain amount of stretching. Therefore, the weight of the floating roller 1 needs to be adjusted and neutralized. To address the above problems, this invention proposes an automatic floating roller weight adjustment device and its operating mechanism. This device balances the weight of the floating roller during the production process, automatically balancing the gravity exerted on the semi-finished parts by the floating roller during production, thus maintaining a zero-pressure, relaxed and stretched state on the tire tread.

[0068] The working principle and beneficial effects of the above technical solution are as follows:

[0069] The floating rod weighing device 3 weighs the floating rod 1 in real time and displays the real-time weight of the floating rod 1 on the floating rod weighing display 2. This device uses a hydraulic cylinder 6 to drive the telescopic rod 7 to extend and retract, thereby driving the weight hammer 8 to extend and retract, realizing the extension and retraction adjustment process of the weight hammer 8. Based on the lever principle, the weight of the floating rod 1 is balanced by the extension and retraction of the telescopic rod 7, setting a required weight range for the floating rod 1. If the weight is within this range, no adjustment is made. If it exceeds this range, it means that the weight pressure exerted by the floating rod 1 on the half-part exceeds the required range, and a weight pressure balancing and neutralization process of the floating rod 1 needs to be performed. The PLC controls the hydraulic cylinder 6 to drive the telescopic rod 7 to extend and retract, and the extension and retraction process is adjustable at each step until the excess weight of the floating rod 1 is neutralized until the weight of the floating rod 1 reaches the required weight range. If the weighed weight of the floating rod 1 is higher than the set range, the hydraulic cylinder 6 drives the telescopic rod 7 to extend forward, and the weight hammer 8 extends forward to neutralize the excess weight of the floating rod 1 until the weight of the floating rod 1 reaches the required set range. If the weight is below this range, adjust accordingly. The hydraulic cylinder 6 drives the telescopic rod 7 to retract, and the weight hammer 8 retracts to neutralize the weight of the floating rod 1 when it is below this range, until the weight of the floating rod 1 reaches the required setting range.

[0070] This invention realizes the automatic adjustment process of the floating roller weight. The adjustment mechanism is complete and the adjustment method is novel. The PLC control adjustment has a high degree of automation and high adjustment accuracy, which is of great significance in actual production.

[0072] The first speed sensor is used to detect the conveying speed of the upper part of the first conveying device 9;

[0073] The second speed sensor is used to detect the conveying speed of the upper part of the second conveying device 10;

[0074] A distance sensor is installed on the output side of the first conveying device 9 to detect the distance between the location of the distance sensor and the target point on the horizontal axis 12. The number of distance sensors is several.

[0075] Force sensors are installed at the connection between the horizontal shaft 12 and the bearing 5 to detect the pressure of the horizontal shaft 12 on the bearing 5. Each bearing 5 corresponds to at least one force sensor.

[0076] An oil inlet detection device is used to detect the oil inlet information of the oil inlet of the telescopic rod 7, wherein the oil inlet information of the oil inlet of the telescopic rod 7 includes: the oil inlet flow rate of the oil inlet of the telescopic rod 7;

[0077] The control device comprises a first alarm and a second alarm. The controller is electrically connected to a first speed sensor, a second speed sensor, a distance sensor, a force sensor, an oil inlet detection device, the first alarm, and the second alarm. The controller controls the first alarm and the second alarm to sound based on the first speed sensor, the second speed sensor, the distance sensor, the force sensor, and the oil inlet detection device. This includes:

[0078] The control device periodically determines a first evaluation value based on a first speed sensor, a second speed sensor, a distance sensor, a force sensor, and a third speed sensor. When the first evaluation value is not within the corresponding preset range, the control device controls the first alarm to sound.

[0079]

[0080] P k This is the first evaluation value for the k-th detection cycle. δ1, δ2, and δ3 are the first, second, and third influence coefficients, respectively (values ​​greater than 0 and less than 1, considering the conveying speed of the half-parts). N is the total number of force sensors, and F... ki1 F is the average value of the actual detection value of the i-th force sensor in the k-th detection cycle. ki2 F is the preset reference value of the i-th force sensor in the k-th detection cycle. ki0 For |F ki1 -F ki2 | The corresponding maximum permissible deviation value, d kj2 Let d be the actual detection value of the j-th distance sensor in the k-th detection cycle. kj1 v is the preset reference value of the j-th distance sensor in the k-th detection cycle. k2v is the average value of the actual detected values ​​of the second velocity sensor in the k-th detection cycle. k1 v is the average value of the first velocity sensor reading in the kth detection cycle; k3 v is the preset reference value of the second velocity sensor in the k-th detection cycle. k0 For |v k2 -v k1 | Corresponding preset baseline value, d kj0 For |d kj2 -d kj1 | The corresponding maximum allowable deviation value;

[0081] When the first alarm does not sound, the second evaluation value τ is determined based on the first speed sensor, the second speed sensor, the oil inlet detection device, and the first evaluation value. If the second evaluation value τ is not within the corresponding preset range, the control device controls the second alarm to sound.

[0082]

[0083] Q is the actual oil flow rate detected by the oil inlet detection device, γ is the preset coefficient, S is the area of ​​the oil inlet chamber of the telescopic rod along the direction perpendicular to the oil inlet, Q0 is the preset maximum allowable oil flow rate of the oil inlet of the telescopic rod 7, and ln is the natural logarithm.

[0084] The beneficial effects of the above technical solution are as follows: by setting a first speed sensor, a second speed sensor, a distance sensor, a force sensor, and an oil inlet detection device, the working status of the balancing mechanism of the present invention (composed of a first support 11, a horizontal shaft 12, a first connecting mechanism, a counterweight structure, a support frame 4, and a floating roller weight weighing device 3) can be monitored in real time to obtain the real-time feeding status (detection value of the first speed sensor), discharging status (detection value of the second speed sensor), position deviation status information of the floating roller (detection values ​​of multiple distance sensors and multiple force sensors), and oil inlet status information of the telescopic rod (detection value of the oil inlet detection device). Then, based on the periodic feeding status, discharging status, position deviation status information of the floating roller, and oil inlet status information of the telescopic rod, the stability of the balancing mechanism is comprehensively evaluated to obtain the first evaluation value of the current detection cycle. When the first evaluation value is not within the corresponding preset range, the control device controls the first alarm to alarm, indicating that the balancing mechanism is in an abnormal stable state. At this time, the alarm is used to repair the balancing mechanism. In the corresponding formula (1): The horizontal axis is judged to be properly supported by the state of multiple support points of the horizontal axis and bearings, and the state of the horizontal axis is judged to be normal by whether the position of multiple points of the horizontal axis deviates, so as to avoid the abnormal state of the horizontal axis affecting the balance effect. The feeding and discharging speeds of the half-parts at the floating roller are used to determine whether the conveying status of the half-parts is normal. When the conveying status of the half-parts is abnormal, the balancing mechanism may not be able to work normally and reliably.

[0085] When the balancing mechanism is in a stable state, the second evaluation value τ is determined based on the stable state of the balancing mechanism, the first speed sensor, the second speed sensor, the oil inlet detection device, and the first evaluation value; in formula (2), γv2S reflects the working speed of the telescopic rod. It reflects the reaction state of the equilibrium mechanism. When the conveying speed of the semi-component is abnormal compared to the working speed of the telescopic rod, it may be due to the slow response of the balancing mechanism causing the floating roller to squeeze and deform the semi-component. Furthermore, the second evaluation value takes into account the overall balance state of the balancing mechanism (while the first evaluation value obtained solely from the overall balance state of the balancing mechanism may not be sufficient for the first alarm, a deviation in the overall balance state, or the responsiveness of the balancing mechanism, could affect the overall balance effect and trigger an alarm), making the evaluation more reliable. Monitoring allows for reliable detection of the entire balancing mechanism's operation, providing timely alarms and reminders for maintenance in case of abnormalities.

[0086] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
