Description

Technical Field

[0001] The invention relates to the technical field of water control and water removal of semi-components, in particular to a pulsating wind pressure regulating device. Background Art

[0002] The production of extruded rubber semi-components needs to go through a cooling process. Spraying, immersion and other methods are generally used in the cooling process, which causes water stains on the semi-components before they come off the line. Water stain treatment is required to control water removal.

[0003] At present, the water removal device mainly adopts the method of air knife water blowing. The air knife device spans the frame above the linkage line and is set on the top of the frame. It uses a high-pressure fan to provide wind pressure, thereby realizing the water removal and water control process of the semi-component. However, due to the different thicknesses of the semi-components, water is easily accumulated between the height differences of the semi-components, and the water blown to the edge of the tread is easy to cause water accumulation due to surface tension and tread warping. Using the same wind pressure cannot adapt to the changes in the above situation. This leads to problems such as incomplete water blowing off the line and unqualified water control, which cannot meet the process requirements. Therefore, the current water control and water removal control system for the production of semi-components is not reasonable in terms of intelligence, standardization, and structuring. In daily production, unqualified water control and water removal off the line often occur, resulting in water stains before the extruded semi-components are off the line, affecting product stability and process operation control of subsequent processes.

[0004] Based on this, a pulsating wind pressure regulating device is now provided to eliminate the drawbacks of the existing devices. Summary of the invention

[0031] In one embodiment, Figure 5-Figure 6 As shown, the installation mechanism 7 includes a connecting groove 701, a limiting groove 702, a connecting block 703, a limiting block 704, a slot 705, a humidity detection probe 706, a slide bar 707, a spring 708 and a pull rod 709. The bottom of the fixed frame 6 is provided with multiple groups of connecting grooves 701, and both sides of the connecting groove 701 are provided with limiting grooves 702.

[0040] The above embodiment discloses a pulsating wind pressure regulating device, wherein, when in use, the humidity detection probe 706 is inserted into the connecting groove 701 and the limiting groove 702 through the connecting block 703 and the limiting block 704, the pull rod 709 is pulled to move the slide bar 707 backward, the spring 708 is stretched, and after the connecting block 703 and the limiting block 704 are completely inserted into the connecting groove 701 and the limiting groove 702, the pull rod 709 is released, the spring 708 is reset, and one end of the slide bar 707 is inserted into the card slot 705, so that the humidity detection probe 706 is fixed to the fixing frame 6 through the connecting block 703 and the limiting block 704, thereby completing the installation of the humidity detection probe 706, and placing the half-component tread on the rubber On the rubber half-component conveyor 1, the humidity of the half-component tread is measured by the humidity detection probe 706, and the detected humidity is transmitted to the PLC module as an input signal to determine whether it is within the standard requirement range. According to the standard range requirements, the PLC module transmits a signal to the electromagnetic proportional control valve 13, so that the electromagnetic proportional control valve 13 controls the size of the air duct, starts the drive motor 3, and the drive motor 3 rotates through the belt 5 and multiple groups of transmission wheels 4, and then the half-component tread is transmitted to the bottom of the wind knife plate, and the wind pressure is provided by the high-pressure fan 8. The wind force is transmitted to the air supply pipe 10 along the air storage chamber 9, and the wind pressure is blown from the blowing port 15 on the blowing knife plate 14 through the air supply pipe 10, so as to blow and remove water from the tread.

[0041] When the detection value of the humidity detection probe 706 is transmitted to the PLC module, the PLC module determines that if it is higher than the standard range requirement, then the PLC module transmits a signal to the electromagnetic proportional control valve 13, the electromagnetic proportional regulating valve controls the size of the air duct, and the opening ratio of the electromagnetic proportional control valve 13 increases (PLC control, the percentage of single opening of the electromagnetic proportional regulating valve can be set manually, such as single opening of 20%), the larger the opening ratio of the electromagnetic proportional control valve 13, the better the effect of blowing and removing water, after the interval stabilization time (the electromagnetic proportional control valve 13 progressively adjusts the opening ratio, after the tread humidity is stable, PLC control, the interval time can be adjusted according to the actual production equipment, manually set, such as setting the interval time after a single adjustment to 3min), if the detected humidity is still higher than the standard requirement, the PLC module transmits a signal to the electromagnetic proportional control valve 13, the electromagnetic proportional control valve 13 progressively opens the ratio size until the electromagnetic proportional regulating valve opening degree reaches the maximum (PLC progressively controls the electromagnetic proportional regulating valve to open) any of the above operation steps, the humidity detection probe 706 reaches the standard requirement range, and the operation process is terminated. (PS: PLC control, after the distance adjustment device is adjusted, there will be an interval time, and the tread humidity will be stable before the next adjustment operation. The interval time can be set manually. For example, after a single distance device is adjusted, the interval is 3 minutes. After 3 minutes, the PLC determines that the adjustment is completed, and then receives the humidity signal to determine whether the next adjustment operation is required).

[0042] When the detection value of the humidity detection probe 706 is transmitted to the PLC module, the PLC module determines that it is lower than the standard range requirement, and then the PLC module transmits a signal to the electromagnetic proportional control valve 13, the electromagnetic proportional control valve 13 controls the size of the air duct, and the opening ratio of the electromagnetic proportional control valve 13 is reduced (PLC control, the percentage of single closing of the electromagnetic proportional control valve 13 can be set manually, such as single closing of 20%), the larger the closing ratio of the electromagnetic proportional control valve 13, the worse the effect of blowing and removing water, after the interval stabilization time (the electromagnetic proportional control valve 13 progressively adjusts the closing ratio, after the tread humidity is stable, PLC control, the interval time can be adjusted according to the actual production equipment, manually set, such as setting the interval time after a single adjustment to 3min), if the detected humidity is still lower than the standard requirement, the PLC module transmits a signal to the electromagnetic proportional control valve 13, the electromagnetic proportional control valve 13 progressively closes the ratio until the electromagnetic proportional adjustment valve opening degree reaches the minimum (PLC progressively controls the electromagnetic proportional adjustment valve to open) in any of the above operation steps, the humidity detection probe 706 reaches the standard requirement range, and the operation process is terminated. (PS: PLC control, after the distance adjustment device is adjusted, the interval time is to wait until the tread humidity is stable before the next adjustment operation process is carried out. The interval time can be set manually. For example, after a single distance device is adjusted, the interval is 3 minutes. After the PLC determines that the adjustment is completed after an interval of 3 minutes, it receives the humidity signal and determines whether the next adjustment operation process is required). Then, through the adjustment control of the electromagnetic proportional control valve 13, the blowing air pressure adjustment of the half component is realized, thereby further accurately controlling the tread humidity and improving the tire production quality.
