A guide rod slot 15 is provided on the outside of the detection frame 10. A guide rod 16 runs through the guide rod slot 15. A second bracket 17 is fixedly connected to the end of the guide rod 16 close to the outside of the detection frame 10. A third guide roller 18 is rotatably connected to the inner side of the second bracket 17. A baffle 20 is fixedly connected to one end of the guide rod 16 located in the conductive slot 14. A conductive rod 21 runs through the baffle 20. A conductive spring 22 is installed on the inner wall of the conductive slot 14 corresponding to the conductive rod 21. The conductive spring 22 is electrically connected to the power supply 11 and the control switch 13 through an electrical connection line 23.

[0024] When the transmission device is in use, the material bypasses the top of the second guide roller 5, the bottom of the first guide roller 4, the side of the third guide roller 18 and the top of the active roller 2, and the active roller 2 is driven to rotate by the motor, and the active roller 2 drives the material to move by friction. When the material is tensioned, the material drives the third guide roller 18 to overcome the elastic force of the second spring 19, so that the conductive spring piece 22 and the conductive rod 21 are misaligned, so that the alarm 12 is in a power-off state.

When the material passes through the first guide roller 4, the first guide roller 4 overcomes the elastic force of the first spring 9 and moves upward. At the same time, the first guide roller 4 is elastically pressed against the material through the first spring 9, which can form a certain elastic space, so that the first guide roller 4 fluctuates to a certain extent, preventing the material from being deformed, torn and locally thinned due to changes in force.

[0027] Working principle: For this single-sided impregnating machine transmission device, when the transmission device is in use, the material bypasses the top of the second guide roller 5, the bottom of the first guide roller 4, the side of the third guide roller 18, and the top of the driving roller 2. The driving roller 2 is driven by a motor to rotate, and the driving roller 2 drives the material to move through friction. When the material is tensioned, the material drives the third guide roller 18 to overcome the elastic force of the second spring 19, causing the conductive elastic sheet 22 to be misaligned with the conductive rod 21, and the alarm 12 to be in a power-off state. When the material is disconnected, the second spring 19 drives the conductive rod 21 to abut against the conductive elastic sheet 22, causing the alarm 12 to be powered on and emit an alarm. When the device stops working, the conductive state of the electrical connection line 23 is directly disconnected through the control switch 13 to prevent the alarm 12 from emitting an alarm by mistake. Through this single-sided impregnating machine transmission device, the state of the material can be monitored, avoiding the need for staff to constantly observe the device state, reducing the labor intensity of the staff. When the material passes through the first guide roller 4, the first guide roller 4 moves upward against the elastic force of the first spring 9. At the same time, the first guide roller 4 elastically abuts against the material through the first spring 9, forming a certain elastic space, so that the first guide roller 4 fluctuates to a certain extent, preventing the material from being deformed, torn, or locally thinned due to changes in the force applied.
