Detailed Description

The present invention will be further described with reference to the accompanying drawings, and the following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4, the utility model provides a two twisters main shaft pulley device mainly is applied to the stranding rope-stranding device in the steel cord production process, can promote frock maintenance cycle, can effectively solve the bad problem of system of twisting of 1+6 core strand cord. The main structure comprises a right main shaft pulley 1, a right flywheel disc 2, a U-shaped clamping groove 3, a left flywheel disc 4 and a left main shaft pulley 5.

The right main shaft pulley 1 and the left main shaft pulley 5 are respectively installed in the right main shaft and the left main shaft of the double-twisting machine, and the right main shaft pulley 1 and the left main shaft pulley 5 are made of YG8 hard alloy. The right flywheel disc 2 and the left flywheel disc 4 are respectively arranged on a right main shaft and a left main shaft of the double-twisting machine. Main shaft pulley is the production of same cell type mode about among the prior art, the utility model discloses two main shaft pulleys about well are different cell types, have seted up V type groove 11 on the right main shaft pulley 1 promptly, have seted up U type groove 51 on the left main shaft pulley 5. In the twisting process, the defect that 0720 folded yarn twisting is poor due to the change of tension is prevented, the product quality index can be effectively improved, and the production efficiency and the primary yield of the 0720 folded yarn are improved. According to different production specifications of products, the groove shapes of the left main shaft pulley and the right main shaft pulley are not changed, and the size of the groove shape can be properly changed.

The right flywheel disc 2 and the left flywheel disc 4 are both bell-shaped flywheel discs with smooth surfaces, and the positions through which the strands pass are YG8 hard alloy U-shaped clamping grooves 3. The U-shaped clamping groove 3 is consistent with the V-shaped groove 11 and the U-shaped groove 51 in center position. If the deviation exists, the elastic screw of the flywheel disc is adjusted to return to the original position.

The utility model discloses a working process does: in the threading step of the machine tool, 0720 folded yarns led from the lead sequentially pass through the right main shaft pulley 1 and then pass through the right flywheel disc 2, and the folded yarns pass through the middle of the U-shaped clamping groove 3; continuously passing through the U-shaped clamping groove 3 from the left flywheel disc 4 to the left main shaft pulley 1 in sequence, and finally continuously threading to the take-up I-shaped wheel; and starting up the production operation after the lead joint is finished.
