Embodiment Construction
[0036] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0037] The manufacturing process of a concave straw mat of the present invention comprises the steps of laying wadding, pressing and binding, and is characterized in that:
[0038] 1) The overlapping amount of the grass in the wadding is set to 200-350mm,
[0039] 2) The working pressure in the pressing process is set to 4-5 times of the bearing pressure of the straw pad,
[0040]3) Measure the pressure on each part of the concave grass pad through the uniformly distributed pressure sensors arranged on the lower mold, and display the measured pressure on the display of the control panel in real time on the display of the control panel and send it to To the PLC controller, the PLC controller compares the measured pressure on each part of the concave grass mat with the set value,
[0041] 4) The pressing position of both sides of t...
