Embodiment Construction

[0040] The present invention will be further described in detail through the accompanying drawings and specific embodiments below.

[0041] Such as figure 1 Shown, a kind of rubber strip width closed-loop control method, comprises the following steps:

[0042] S1, obtaining the real-time width value of the rubber strip; further, in S1, when obtaining the width value of the rubber strip, the following steps are included: obtaining the position pixel where the infrared light source is blocked by the rubber strip and reflected on the reflector; calculate according to the position pixel The width value of the rubber strip can be specifically, according to the number of pixels between the counting position pixel and the relative two sides, it can be used as the real-time width value of the rubber strip. In this application, the infrared width measuring sensor is used to directly output the analog quantity of the measurement signal After converting the analog quantity to digital, t...

Abstract

The invention discloses a closed-loop control method and a closed-loop control device for the width of an adhesive tape. The method comprises the following steps: a real-time width value of the adhesive tape is acquired; the real-time width value is read in a time-sharing mode, timing interruption is set for PID calculation, the actual speed ratio value between an extruder and a profiling roller is calculated, and the obtained actual speed ratio value is compared with a preset standard speed ratio value; according to the difference value between the actual speed ratio and the preset standard speed ratio, the profiling speed of a profiling roller is adjusted; the real-time width value of the adhesive tape is collected again, and the steps are repeated to achieve closed-loop control over the width of the adhesive tape. The device is used for implementing the method, the width of the adhesive tape is obtained in real time, the width value of the adhesive tape is read in a time-sharing mode, whether the profiling / extrusion speed ratio meets the preset standard value or not is judged according to the width value of the adhesive tape through timing interruption, the profiling roller is adjusted, stretching / stacking of the adhesive outlet profiling adhesive tape is controlled, and therefore the width of the adhesive is controlled to be stable.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a closed-loop control method and a control device for the width of rubber strips. Background technique [0002] In the production and manufacture of tires, due to the higher requirements for splicing precision of high-end tire sections and the requirement that the special parts of giant tires cannot be extruded at one time, it is necessary to carry out profiling winding on tires, in order to ensure the stability of winding size and weight during winding , it is necessary to precisely control the section of the winding rubber strip, because the rubber strip extruded by the pressing roller presents a special trapezoid, the stretching angle of the rubber strip, the width data of the rubber strip can be detected and controlled, and the cross section of the rubber strip can be correlated with the mapping. Due to the vibration and deformation of the rubber strip under differ...
