The pulling net driving roller 31 is connected with the tension roller 33 through the pulling net belt 25, the pulling net driven roller 32 is arranged outside the pulling net belt 25 and is driven by the friction force of the belt (pulling net belt 25), the tension roller 33 can adjust the tension of the pulling net belt 25 through the displacement of the adjustable bearing seat on the left and right sides, the adjustment relies on the second tension adjusting bolt 225 to control, so that the adjustable bearing seat drives the tension roller 33 to slide back and forth in the fixed slot (adjustable bearing seat long hole) of the left bracket welding 35.The other side shaft head of the pulling net driving roller 31 is provided with an electromagnetic clutch (electromagnetic force clutch 29), the electromagnetic clutch (electromagnetic force clutch 29) is connected with a power supply, the electromagnetic clutch (electromagnetic force clutch 29) is connected with the upper end pulley 217 through the belt 216, the pulley 217 is coaxially installed with the net conveying rubber roller 21, the two net clamping steel rollers 22 are installed on the two sides of the net conveying rubber roller 21, and are tightly pressed on the net conveying rubber roller 21 under the action of the tension spring 226, so that the tension spring 226 can press the net in a tight manner, the net is placed in the net placing frame 26, the net is rotated and laid, the net is passed from above the upper end spiral net spreading rod 221, the separating lever 227 is pressed downward, until the two net clamping steel rollers 22 are separated from the net conveying rubber roller 21, then the net is passed from below the gap between the first net clamping steel roller (one of the two net clamping steel rollers 22) and the net conveying rubber roller 21 to the upper end, then the net is passed from below the gap between the second net clamping steel roller (the other of the two net clamping steel rollers 22) and the net conveying rubber roller 21 to the upper end, at this time, the separating net clamping steel roller 22 is pulled upward, so that the two net clamping steel rollers 22 and the net conveying rubber roller 21 clamp the net, finally, the net pressing rod 27 is pulled downward, so that the net is rolled and pressed tightly, and the net is prevented from jumping during the test, and the working principle is as follows: when the electric control equipment and the mechanical equipment are normally connected, the power supply is started, the speed of the direct current motor is adjusted through the display, the speed range is adjustable 0-3200r / min, the direct current motor (driving mechanism 211) drives the pulling net driving roller 31 to rotate, when the electromagnetic clutch (electromagnetic force clutch 29) is controlled to be powered on for 5s through the display, the electromagnetic clutch (electromagnetic force clutch 29) installed on the other side of the pulling net driving roller 31 drives the net conveying rubber roller 21 to rotate, the net conveying rubber roller 21 pulls the laid net downward through friction, the net on the spiral net spreading rod 221 is pushed to both sides through the spiral pushing force, after 5s, the electromagnetic clutch (electromagnetic force clutch 29) is disconnected, the laid net is pulled down from above under the action of the pulling net driving roller 31 and the pulling net belt 25, at this time, the net conveying rubber roller 21 is passively rotated under the friction of the net, so that the winding net gear 219, the cutter gear 220 and the variable speed gear 228 rotate synchronously, the hanging cutter hook 218 originally hung on the cutter gear shaft and installed on the shaft surface of the net conveying rubber roller 21 is separated from the cutter gear shaft under the action of the rotation of the cutter gear shaft and the friction, at the same time, the net cutting knife 24 rapidly falls under the action of the falling knife spring 212, the net is cut off in a tight state, at the same time, the net cutting knife sensor feeds back the signal of the net cutting knife 24 to the display, the display gives the command signal of the electric push rod 210 to push, the electric push rod 210 pushes the net cutting knife reset rod 229 to push the net cutting knife 24 to the original position, the hanging cutter hook 218 is hung on the cutter gear shaft, when the net cutting knife sensor senses the signal of the net cutting knife 24 again, the electric push rod 210 is retracted.Thus, a working process is completed, the display records that the net winding test is completed once, the net pulling active roller 31 and the net pulling belt 25 throw the net downward, and the net winding and cutting test is completed once. It is worth mentioning that, in order to prevent the net from winding on the net pulling belt 25 and the net pulling passive roller 32, a net removing brush device (net removing brush 34) is arranged on the outer surface of the net pulling belt 25 and the net pulling passive roller 32, and the entire process of the above working cycle is completed.

[0062] It should be noted that the display can be provided with a controller, and the display, the controller, and the control method, analysis method, judgment method and control logic of the sensor are prior art, and those skilled in the art can easily think of how to program to achieve it according to actual needs, which will not be repeated here.
