Referring to fig. 2 and 3, the Contraband-type frame 320 is rotatably connected at its left end to a rotating rod 32a, a belt wheel is mounted on the outer wall of the rotating rod 32a, the outer wall of the belt wheel is slidably connected to a second transmission belt 29, a shift lever 32b is mounted at the left end of the rotating rod 32a, a waist-shaped rod 32c is slidably fitted at the left end of the shift lever 32b, stop rods 32d are symmetrically mounted on the outer walls of the left and right ends of the Contraband-type frame 320, a stop hole is formed at one end of the stop rod 32d away from the Contraband-type frame 320, a movable rod 32e is slidably fitted in the stop hole, the front end of the movable rod 32e at the left end of the Contraband-type frame 320 is connected to the rear end of the waist-shaped rod 32c, a pressing plate 32f is disposed above the paving roller 28, the rear ends of the two movable rods 32e are both connected to the front end of the pressing plate 32f, when the paving roller 28 and the transmission roller 33 rotate, the second transmission belt 29 and the rotating rod can make the paving roller 32a and the paving roller 28 rotate synchronously, dwang 32a drives driving lever 32b and is synchronous rotary motion, under gag lever post 32 d's effect, driving lever 32b drives movable rod 32e with waist type pole 32c cooperation and is linear translation motion, movable rod 32e promotes stripper plate 32f backward, thereby can make stripper plate 32f extrude the net cloth that has just laid, make between net cloth and the outer wall laminating inseparabler, also level and more level simultaneously, net cloth's the effect of laying has been strengthened, and then the practicality of this equipment has been strengthened.

When the equipment is adopted to lay the alkali-resistant mesh cloth for the external wall heat insulation construction, the method specifically comprises the following steps:

s1, installing equipment and checking: before the device is used for laying the alkali-resistant mesh cloth for the external wall heat insulation construction, the fixed base 1 is installed on the existing lifting platform in a manual mode, and then the running condition of the device is checked;

s2, placing a grid cloth roll: the mesh cloth is sleeved on the unwinding roller 20 in a manual mode, the head end of the unwinding roller 20 sequentially penetrates between the leveling rollers 24 and between the conveying rollers 33, then the head end of the mesh cloth is placed at the laying roller 28, and finally the laying roller 28 of the equipment is placed at the highest position of the outer wall through the lifting platform;

s3, laying mesh cloth: when the motor 21 drives the unreeling roller 20 to rotate for unreeling, under the mutual cooperation of the first transmission belt 26, the gear 27 and the second transmission belt 29, the two conveying rollers 33 convey the mesh cloth to the laying roller 28, the laying roller 28 drives the spring rod 284, the roller and the arc plate 285 to do synchronous rotation motion in the rotation process, when the roller moves to the farthest end on the cam 282, the cam 282 can form a top supporting effect on the spring rod 284 and the arc plate 285, so that the arc plate 285 moving to be close to the outer wall expands outwards, and the mesh cloth is laid on the outer wall and is extruded to a certain degree;

s4, cutting the mesh fabric: when the equipment moves to the lowest end of the outer wall along with the lifting platform, the mounting plate 328 and the cutting knife 327 can be driven to synchronously descend by controlling the descending of the air cylinder 329, and the mesh cloth is cut off by the cutting knife 327 under the matching of the baffle 326;

s5, repeat S2-S4: when the whole roll of the mesh cloth is completely laid, the operations in S2-S4 can be repeated, and the mesh cloth laying of the outer wall is continued until the whole outer wall is fully laid with the mesh cloth.
