According to a preferred embodiment of the present invention, the guide rollers are vertically spaced, the semi-finished lawn sequentially passes through the surfaces of the different guide rollers, the guide rollers are driven by external power to roll, and the semi-finished lawn moves along with the rolling of the guide rollers.

Among the above-mentioned technical scheme, above-mentioned deflector roll is right while rolling the operation of punching is carried out to the blanket back in semi-manufactured lawn, and efficiency is higher, adopts physics to prick the hole moreover for artificial turf's blanket back is covered with countless a plurality of little micropore and replaces traditional electric iron to punch, reduces the grass silk damage, stops the waste gas oil smoke that the electric iron punched and produced and discharges, reduces environmental pollution, thereby reaches the environmental protection of artificial turf production process.

According to a preferred embodiment of the present invention, along the moving direction of the semi-finished lawn, heating devices are respectively disposed on two sides of the semi-finished lawn, and heating ends of the heating devices face the semi-finished lawn;

the heating device is actually a modified hot blast stove, and is specially used for the semi-finished lawn which is vertically heated in the invention, and the heating device comprises a hot blast stove main body 1, an air outlet pipeline 2 and a cover body, wherein the hot blast stove main body 1 is provided with an air outlet, and two ends of the air outlet pipeline 2 are respectively communicated with the air outlet and the cover body;

the open sides of the second cover 32 of the two heating devices are arranged oppositely, and a certain distance is formed between the two covers to form a passage for the semi-finished lawn 1P to pass through.

In the above embodiment, the two second cover bodies 32 of the two heating devices are used to erect the semi-finished lawn 1P to be dried between the two second cover bodies for heating and curing, compared with conventional direct open heating, the heat carried by hot air cannot be dissipated, and the heating and curing efficiency is higher.

Considering that the artificial grass fiber is adhered to one surface 1P of the semi-finished lawn, the surface is uneven, the two ends of the second cover bodies are directly utilized to seal the semi-finished lawn, the sealing effect is greatly reduced, since the distance reserved between the open sides of the two second enclosures 32 is too wide, the sealing is poor, and the distance is too narrow, which may cause the semi-finished lawn to be crushed and deformed, in order to solve the above problem, in this embodiment, a ring of seal bristles 33 is further disposed circumferentially on the open side of the second cover 32, and the seal bristles 33 are made of a flexible and deformable rubber which, when pressed against the artificial grass fibre, can deform along with the deformation, and the sealing brush bristles 33 at different positions can deform to different degrees along with the deformation degree of the artificial fibers at different positions, therefore, the extrusion deformation of the semi-finished lawn can be avoided while the efficient sealing is realized.

In addition, considering that different batches of semi-finished lawns to be heated and cured have different humidity or different requirements for dryness, and therefore the hot air speed and the air volume need to be regulated, in the embodiment, the second cover body 34 is internally and transversely provided with the partition plate, the partition plate is provided with the plurality of high-pressure nozzles 35 and the plurality of circulation holes 36, the circulation holes are controlled to be opened and closed by the electromagnetic valves, the high-pressure nozzles 35 and the electromagnetic valves are controlled to be opened and closed according to actual requirements, so that the hot air speed and the hot air volume can be controlled, when the conventional air speed can meet the drying requirement, the electromagnetic valves are opened, the circulation holes 36 are used for passing through, if the conventional air speed and the conventional air volume cannot meet the drying requirement, the high-pressure nozzles are opened, and the high-pressure hot air is sprayed by the high-pressure nozzles, so that. And if the wind speed and the wind volume do not meet the requirements, simultaneously opening the electromagnetic valve and the high-pressure spray nozzle 35.

Moreover, when the surface to be dried is large, the drying area needs to be enlarged, so the second cover 32 is provided with a folding structure, and the length of the second cover in the vertical direction is variable, so that the length of the second cover 32, that is, the size of the drying area can be adjusted according to actual requirements;

according to a preferred embodiment of the present invention, a plurality of limiting rods 37 are vertically arranged in the second cover body 32 at intervals, the limiting rods 37 in the second cover body 32 of the two heating devices are respectively in one-to-one correspondence and are correspondingly arranged, and a certain distance is arranged between the two corresponding limiting rods 37, so that the semi-finished lawn can pass through the distance.

In the above-mentioned embodiment, when adopting a large amount of high-pressure steam of high pressure shower nozzle blowout simultaneously, probably causing the flutter on semi-manufactured lawn, can heat the effect and cause the influence, consequently in this scheme the second cover body 32 internal vertical interval sets up a plurality of gag lever posts 37 to establish the card with semi-manufactured lawn spacing in the middle, in order to avoid semi-manufactured lawn to flutter.
