The rotating shafts 4 rotate to realize the rotating embossing of the upper embossing roller 2 and the lower embossing roller 3. The outer surfaces of the two rotating shafts 4 are rotatably connected with connecting blocks 5. The disassembly and assembly process is carried out by connecting and separating the connecting blocks 5 and the frame 1. The connecting blocks 5 have a good supporting effect on the rotation of the upper embossing roller 2 and the lower embossing roller 3, so that the upper embossing roller 2 and the lower embossing roller 3 can rotate stably. Two clamping grooves 6 corresponding to the positions of the connecting blocks 5 are opened on the inner side of the frame 1. The connecting blocks 5 are inserted into the clamping grooves 6, and the machine Two-way threaded rods 7 are rotatably connected to the positions near the positioning grooves 6 on both sides of the frame 1. The thread force generated between the rotation of the two-way threaded rods 7 and the positioning blocks 8 drives the two positioning blocks 8 on a two-way threaded rod 7 to move toward each other close to the connecting block 5 until one side of the positioning block 8 is tightly fitted with the connecting block 5. Two positioning blocks 8 are threadedly connected to the upper and lower parts of the outer surface of the two-way threaded rod 7. The positioning block 8 presses against one side of the connecting block 5 to close the gap of the positioning groove 6. The positioning groove 6 and the positioning block 8 cooperate to fully limit and fix the connecting block 5, so that the upper embossing roller 2 and the lower embossing roller 3 are stably installed on the inner side of the frame 1 to participate in the embossing work of the fabric. Guide grooves 9 corresponding to the positions of the two positioning blocks 8 are provided on both sides of the frame 1. The positioning block 8 slides longitudinally along the guide grooves 9 to make it more stable.
