The method comprises the following steps: S10, carrying out continuous and sequential slitting on a large lug part material belt by adopting a lug part short-cutting device, thus forming a left lug part A and a right lug part B; and S20, adsorbing the cut left lug part A and right lug part B by a first adsorbing cutter anvil and a second adsorbing cutter anvil, respectively, and enabling the cut left lug part A and right lug part B to rotate along with the first adsorbing cutter anvil and the second adsorbing cutter anvil. The invention further provides a system for realizing the large paper diaper lug part short-cutting longitudinal pitching method. The system comprises the lug part short-cutting device, a transmission-side longitudinal pitching device, an operation-side longitudinal pitching device and a left-right side lug part pitching device, and the transmission-side longitudinal pitching device and the operation-side longitudinal pitching device are respectively arranged at the outer side of the lug part short-cutting device. The method and the system have the advantages that the structure is simple, the use is convenient, the stability is good, and the waste caused by raw material cutting can be effectively avoided.

The invention discloses a motor rotor accessory structure with a low-temperature winding. The motor rotor accessory structure comprises: a supporting seat; a rack arranged on the supporting seat and defining a mounting space; a hollow rotating shaft arranged in the mounting space and capable of rotating relative to the rack; a sealing assembly arranged between the hollow rotating shaft and the rack; and a gas sucking opening formed in the rack and communicated with the hollow rotating shaft cavity of the hollow rotating shaft. According to the invention, by matching the rack, the hollow rotating shaft and the gas sucking opening, two ends of the hollow rotating shaft are respectively communicated with the motor rotor vacuum cavity, and the motor rotor in rotary work can continuously discharge gas through the gas sucking opening, so that the situation that the air pressure of the vacuum cavity of the motor rotor rises due to tiny leakage or partial material deflation in the vacuum cavity of the motor rotor can be prevented, and shutdown maintenance and inspection of the motor due to leakage of the vacuum cavity of the motor rotor are avoided.

The invention relates to a printing method for a point-of-sale (POS) machine trading center based on threshold limit value (TLV) format data. The printing method comprises the following steps of sending out a printing instruction; printing a configured title; sequentially reading printed contents; directly printing the read contents if the read printed contents do not contain tags; if the read printed contents contain tags, analyzing TLV data structures corresponding to the tags to obtain contents of the tags, formatting the contents of the tags according to attributions, replacing the tags in the printed contents with formatted contents of the tags and then performing printing; and printing configured inscriber. By means of the printing method, tag data are obtained from the trading processing result TLV data structures in the aspect of the printed contents, printing can be configured flexibly, and printing formats can be reasonably configured. When the printing variable is updated, a background program does not need updating, so that trade smoothness is ensured, shutdown maintenance of the trading center caused by updating of the background program is avoided, and business losses of an acquirer are reduced to the largest extent.
