The two ends of the heating roller 2 are rotatably connected to the frame 1, and heating is realized through a hot oil pump circulating system. Preferably, the two heating rollers 2 share a hot oil pump circulation system, namely, hot oil enters the heating roller 2 from the end part of one heating roller 2, exits from the other end part of the heating roller 2, enters the heating roller 2 from the end part of the other heating roller 2 through an oil delivery pipe, and finally exits from the other end part of the latter heating roller 2 back into the circulation system.

As shown in fig. 4, the tension roller 3 includes a fixed roller 31 and a movable roller 32. The fixed roller 31 is rotatably connected to the frame 1, and its top surface is flush with the top surface of the uppermost heating roller 2. The moving roller 32 is rotatably disposed on the frame 1 and disposed under the fixed roller 31, and is capable of moving up and down relative to the frame 1 by a lifting mechanism. The adjustment of the fabric tension is achieved by adjusting the distance between the fixed roller 31 and the movable roller 32. The lifting mechanism comprises a sliding block 33, a screw rod 34 and a driving motor 35. The sliding blocks 33 are fixed to both ends of the moving roller 32, and are slidably disposed on the frame 1. Specifically, a slide rail is provided on the frame 1, and the slider 33 is slidably disposed in the slide rail. One of the slide rails penetrates the frame 1 and the corresponding slide 33 extends outside the frame 1. The screw rod 34 penetrates through and is in threaded connection with the sliding block 33, and the end part of the screw rod is in transmission connection with the driving motor 35. The screw rod 34 is in threaded connection with a part of the sliding block 33 extending to the outside of the frame 1, and the driving motor 35 is fixed on the frame 1 and is arranged above the sliding block 33. Further, a protective cover is arranged outside the sliding rail, the sliding block 33 and the screw rod 34. The driving motor 35 is connected with a power supply and a control device, the control device controls the driving motor 35 to rotate so as to drive the screw rod 34 to rotate, and the screw rod 34 drives the sliding block 33 to move up and down, so that the lifting movement of the moving roller 32 is realized.
