1. Laying of the membrane unit into the ground and to be laid the center line of the ridge (ridge) on the positive, the film will be used in military pulled out backward 0.5-1 meters, and press on firmly end and the both sides, the film pressing wheel pressure on both sides of the ground, can be a formal operation. 2 unit operations to be uniform, straight line. Using animal traction film machine, be sure to hold livestock, in order to ensure the paving quality. 3. The homework and auxiliary personnel should always check the ditching and ridging, spraying, PU film, film, covering soil, drilling and sowing operation quality, once discovered, immediately stop check. 4 units in turn, keep the head cut after the film dosage, then, artificial resow shop, and then press firmly. 5 after the shop, in the film 1~2 meters per space on a small amount of pressure on the soil, in order to prevent the wind blow film.
Common failures and troubleshooting
1 transverse wrinkles. This is due to the plastic film longitudinal tension is less than the transverse tension, forward speed is not uniform, and other reasons. Solution: reduce the two round of film pressure; increase film roll clamping force; the speed of the machine should be uniform. 2 longitudinal wrinkles. This is due to the film's longitudinal tension is greater than the transverse tension and other reasons. Solution: increase of about two round of film pressure; reducing film roll clamping force; appropriate to reduce the speed of the machine.
3 oblique wrinkles. The reason is when the traction unit failed to move in a straight line, or about the film size is inconsistent with the wheel pressure. Solution: to improve the technological level of operation, the unit line adjustment; two film wheel, so the pressure is uniform.
4 plastic film deflection. Is a result of the unit failed to line, or the film coil installation is not, the film volume itself caused by the uneven. Solution: the film roll to the border and with the unit forward vertical direction; unit should be uniform, linear driving; roll film inspection, if necessary, replacement.
The 5 film pressed film wheel. This is due to the unit running, plastic film and the width of the border surface is not complete and the film itself winding of poor quality causes should be solved in the light of specific circumstances.
6 after the film roll, both sides of the broken. To roll the edges should be pressed film wheel pressure increases, covering shovel angle decreases, the adjustment covering shovel and plastic film between the distance. Broken film phenomenon, should be reduced by two round of film pressure, check the quality of the land.
