Middle pressing roller device of home thread spinner

The invention provides a middle pressing roller device of a home thread spinner. The middle pressing roller device comprises a motor which provides power transmission for the whole pressing roller device. A large pressing roller is fixed at the corresponding front side of the motor in a transmission mode. A small pressing roller is fixedly arranged below the left side of the large pressing roller. An opposite-pressing roller is arranged below the small pressing roller. The space distance between the small pressing roller and the opposite-pressing roller can be adjusted, and then opposite pressing is carried out. A lapping machine is arranged on the upper portion of the large pressing roller. Supporting wall plates are fixedly arranged on the two sides of the lapping machine. The mounting position width of the supporting wall plates is larger than the mounting total width of the motor and the large pressing roller. A net conveying curtain which is in corresponding net connection with the lapping machine is arranged on the lower side face of the lapping machine in a paving mode. An oblique conveying curtain is arranged at a position corresponding to the edge of the opposite-pressing roller on the lower side part of the opposite-pressing roller. The oblique conveying curtain is provided with a pre-pressing machine leftwards. A plurality of thick cotton spinning layers and chemical fiber layers conveyed out by the lapping machine can be subjected to pre-pressing, thicknesses are lowered, then after pressing layer binding, conveying is carried out, the device has the advantages that a power transmission mechanism cannot increase the burden of a middle process, and synchronous operation does not affect the quality of a spinning quilt core.
