[0036] In this embodiment, if Figure 1 As shown, the outer wall of the heating stretching box 1 is marked with scales below the first moving groove and the second moving groove. When the heated tarpaulin is stretched, the first motor 41 is started to drive the double-sided toothed synchronous belt 44 to move, drive the receiving plate 61 to move and then drive the limit plate 75 to move, thereby driving the first hexagonal bidirectional threaded screw 64 and the second hexagonal bidirectional threaded screw 73 to move, so that the first moving block 65 and the second moving block 74 slide in the first moving groove and the second moving groove respectively.

[0042] Working principle: Before heating and stretching the tarpaulin, the third hexagonal two-way threaded screw 163 is rotated to make the two third sliding plates 161 approach each other on the fixed loading block 164 to limit the upper and lower ends of one side of the tarpaulin, and then the second hexagonal two-way threaded screw 73 is rotated to drive the two second sliding plates 71 to approach each other so that the second clamping plates 72 are approached to each other to clamp the top of the other side of the tarpaulin, and the first hexagonal two-way threaded screw 64 is rotated to drive the two first sliding plates 62 to approach each other so that the first clamping plates 63 are approached to clamp the bottom of the other side of the tarpaulin, and then the infrared heating lamp 8 is started to heat the tarpaulin. After the heating is complete, the first motor 41 is started to drive the first gear 43 to rotate, and then the double-sided toothed synchronous belt 44 is driven to move, thereby driving the second gear 47 to rotate, driving the receiving plate 61 to move, thereby driving the first clamping assembly 6 and the second clamping assembly 7 to move, thereby driving the tarpaulin Stretching is performed. When the first moving block 65 and the second moving block 74 move to the specified scale, the first motor 41 is turned off, and then the first hexagonal bidirectional threaded screw 64, the second hexagonal bidirectional threaded screw 73 and the third hexagonal bidirectional threaded screw 163 are loosened, and then the second motor 21 is started to drive the limit rotating rod 25 to rotate, so that the heated and stretched tarpaulin enters the cooling box 2, and the water pump 28 works to supply the liquid in the cooling box 17 to the nozzle 27, and the liquid is sprayed to the heated and stretched tarpaulin through multiple nozzles 27 to quickly cool the heated and stretched tarpaulin. The utility model drives the limit rotating rod 25 to rotate by the rotation of the second motor 21, and drives the heated and stretched tarpaulin into the cooling box 2, and then uses the nozzles 27 on both sides of the inner wall of the cooling box 2 to evenly cool the tarpaulin, so that the heated and stretched tarpaulin can be quickly cooled, so that the shape of the tarpaulin is fixed, while saving a lot of cooling time, it also improves the yield rate, and has good practical effect.

The control program of the controller can be realized by simple programming by those skilled in the art, so the present invention will not explain the control mode and circuit connection in detail.

[0044] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
