[0002] Calendering is a common and fundamental process in rubber processing. It involves using a calender to produce a uniformly thick rubber sheet or fabric coating from rubber. Specific uses for calendering include sheeting, profiling, gluing, rubbing, laminating, thinning, and straining. Calendering also transports rubber on certain production lines and connects upstream and downstream processes. Currently, calenders in the tire industry primarily target steel cord and fiber cord fabrics. Accurate calendering of these fabrics is crucial to the tire's structure and lifespan.

[0003] At present, during the operation of the production line, people usually observe the rubber material between the calender rollers with the naked eye and manually adjust the amount of rubber supplied. This control method cannot achieve precise control of automated production and is not conducive to improving the qualified rate of cord adhesive attachment in calendering production.

[0075] V1=VH n -VQ n

[0076] V T =VH T -VQ T ;

[0078] 5) Display the real-time segmented volume and total volume of the irregularly accumulated rubber between the two rollers in the form of block histograms and numerical values ​​on the screen (such as Figure 4 shown).

[0079] The present invention provides a method for controlling the total amount of accumulated rubber between the upper and lower rollers of a calender, the method comprising the following steps:

[0080] 1. If Figure 5 As shown, the PLC host reads the quantitative data of the accumulated glue between the upper two rollers and the lower two rollers in real time through the network.

[0081] 2. If Figure 6As shown, based on the total amount of material accumulated between the upper and lower rollers; by comparing the total amount of glue supplied and the matching speed of the glue supply conveyor belt, within the speed difference range of the upper and lower glue supply conveyor belts, the system automatically determines the control mode and automatically adjusts the speed mode and speed & width mode according to the situation;

[0082] Upper tape speed frequency P 上 , the frequency of the tape supply is P 下 ;P=P 上 -P 下 ,

[0083] -3.5HZ<=P<=3.5HZ system enters speed mode;

[0084] When P<-3.5HZ or P>3.5HZ, the system enters speed & width mode.

[0085] When the system is in speed mode (-3.5HZ<=P<=3.5HZ), the system scans the total amount of rubber accumulated between the two rollers every 30 seconds, updates it to the current total amount of rubber accumulated, and automatically compares it with the total amount of rubber accumulated between the standard rollers to determine the five intervals: interval ① glue filling value, interval ② glue filling value - stable glue value 1, interval ③ stable glue value 1 - stable glue value 2, interval ④ stable glue value 2 - overflow value, interval ⑤ overflow value; different proportional constants are matched in different intervals;

[0086] Interval ① glue filling value: within a 30-second cycle, the conveyor belt frequency is linearly increased by 2.75HZ within 2 seconds

[0087] Range ②Glue replenishment value - glue stabilization value: within a 30-second cycle, the conveyor belt frequency increases linearly by 0.75HZ within 0.5 seconds.

[0088] Range ③: Stable glue value 1 - Stable glue value 2: No action

[0089] Range ④ Stable glue value 2-overflow value: within a 30-second cycle, the conveyor belt frequency is linearly reduced by 0.75HZ within 0.5 seconds.

[0090] Interval ⑤ Overflow value: Within a 30-second period, the conveyor belt frequency is linearly reduced by 2.75HZ within 2 seconds

[0091] like Figure 7 As shown in the figure, according to the different total amounts of accumulated rubber, the system quickly adjusts the speed compensation of the corresponding rubber supply conveyor belt motor frequency; at the same time, the training machine is automatically and quickly matched immediately to achieve a stable total amount of accumulated rubber supplied between the two rollers.

[0092] For example, for a certain specification of cord fabric, the upper two rollers are set to have a glue filling value of 1.50L, a stable glue value of 9.00L, a stable glue value of 11.5L, and an overflow value of 26.00; the upper supply speed runs at a frequency of 28.15HZ, the lower supply tape speed runs at a frequency of 27.20HZ, and the real-time accumulation of glue on the upper two rollers is 7.9L;

[0093] The system compares the frequencies of the upper and lower supply tapes in real time. P = P_up - P_down = 28.15 HZ - 27.20 HZ = 0.95 HZ, -3.5 HZ < P < 3.5 HZ. The system determines to enter the speed adjustment mode and passes. At the same time, the total accumulated glue volume read by scanning in 30 seconds is VT = 7.9 L (1.50 L < 7.9 L < 9.00 L), which belongs to interval ②. During the 30-second scanning turnover time, the system controls the upper supply glue conveyor belt to linearly increase the frequency by 0.75 HZ within 0.5 seconds. The upper supply belt will speed up to 28.15 + 0.75 = 28.9 HZ to supply materials between the two rollers; to balance the stability of the accumulated glue between the upper two rollers.

[0094] In the speed & width comprehensive adjustment mode (P < -3.5 HZ, P > 3.5 HZ), according to the total volume of the accumulated glue between the two rollers and the speed frequency of the supply belt, the system comprehensively judges and calculates to implement the conveying speed condition of the supply glue conveyor belt and the compensation adjustment of the rubber strip width; when starting the width adjustment, the system controls the supply glue cutter motor to adjust the width of the rubber strip according to the calculated data of the system, increasing & decreasing the width of the supplied rubber strip to achieve the stability of the total volume of the accumulated glue supplied between the two rollers.
