The invention discloses a preparing method of a PET / PTT parallel complex filament with high self-crimpiness. PET and PTT are sliced, dried and crystallized, afterwards, the PET and PTT are fused separately and subjected to extrusion molding through a parallel-type spinneret plate, oil is applied after cooling, then level 1-3 drafting and heat setting treatment are adopted, during drafting, the total drafting rate is controlled to be 3-3.5, the level-1 drafting rate is 2.8-3.0, and the temperature is controlled to be 75-80 DEG C. According to the preparing method of the PET / PTT parallel complexfilament with high self-crimpiness, methods like multi-level drafting for increasing the drafting rate are adopted, and the effects of improving the fiber strength, moderately lowering the elongationat break, and greatly improving the self-crimpiness are achieved.

The invention discloses a cable limiting device for new energy automobiles, and relates to the technical field of automobile cables. The invention comprises a rotating frame, the inner top of the rotating frame is rotatably fitted with a cable reel, and a slide rail is fixed above the rotating frame inside the rotating frame, a sliding block is slidingly fitted in the sliding rail, and a limit rod is set on the sliding block; The bottom end of the limit rod is fixed with a door frame, and the bottom of the door frame is fixed with two opposite guide plates; the cable reel is wound with a cable body, and the cable body is embedded with clamps at intervals, and the top of the clamp is rotated to fit. There is a hook, and the hook cooperates with the guide plate. The present invention ensures orderly and stable winding of the cable body on the cable reel through the cooperation of the limit rod and the door frame, and ensures the efficiency of cable winding; through the cooperation of the door frame and the hoop, the cable body is guaranteed The non-deflection winding of the reel avoids local twisting of the cable and ensures the efficacy and quality of the cable.

The invention discloses anti-deviation cloth unwinding and winding equipment for non-woven fabric production. The anti-deviation cloth unwinding and winding equipment comprises a workbench, a first roller shaft, a second roller shaft, a third roller shaft, a fourth roller shaft, a winding drum and fixing strips. First roller shaft seats are arranged at the upper end of the workbench. Second rollershaft seats are arranged inside the first roller shaft seats. Third roller shaft seats are arranged inside the second roller shaft seats. A main mandrel is arranged inside the winding drum. Fixing sleeves are fixed around the main mandrel. Sliding rails are correspondingly arranged inside the two ends of the winding drum. The top ends of the fixing strips are connected with the winding drum through folding shafts. According to the anti-deviation cloth unwinding and winding equipment, due to the arrangement of the multiple groups of roller shaft seats and the different heights of each group ofroller shaft seats, the heights of each group of roller shafts are different, so that the non-woven fabrics can be conveniently wound and unwound, and the situation that the non-woven fabrics are mutually wound in the unwinding and winding processes is avoided; and a winding method is simple, easy to implement, low in cost and generally applicable to a large number of manufacturers.

The invention belongs to the technical field of dendrobium processing, in particular to a drum-type drying device for dendrobium officinale processing. Aiming at the problems that the drying uniformity of a traditional dendrobium drying device is poor and the subsequent drying quality is influenced, the drum-type drying device for the dendrobium officinale processing comprises a rotary drum; a drying tank and bases with support legs welded at four corners at the bottom; two sides of the outer wall of one side of the rotary drum are vertically welded with fixed plates; one sides of the two fixed plates are respectively provided with mounting circular grooves used for mounting the drying tank; two ends of the rotary drum are respectively welded with fixed rings; and one sides, opposite to the mounting circular grooves, of the fixed rings are respectively provided with first annular grooves. According to the drum-type drying device for the dendrobium officinale processing, a second driving mechanism is arranged, the rotary drum can be driven to stably rotate through a second worm and a worm gear tooth ring, so that the drying tank is driven to overturn, due to the fact that a rise angle of the second worm and the worm gear tooth ring is smaller than a friction angle, the drying device has good self-locking property, stable overturning of the drying tank is realized, and the advantages of convenient loading and unloading are achieved.

The invention discloses a full-stretched silk spinning system based on porous ultrafine denier yarn and its technology, which includes an outer support, the bottom of the outer support is fixedly connected with a base, and the top of the outer support is fixedly connected with a support plate. The rear side of the support plate is fixedly connected with a transmission box, the left side of the top of the support plate is provided with a finishing box, the inside of the finishing box is provided with a finishing mechanism, and a winding mechanism is provided between the opposite sides of the support plate. It relates to the technical field of spinning processing. Based on the porous ultra-fine yarn full-drawn spinning system and its technology, a winding mechanism is provided, and the drive motor in the transmission unit is used to drive the rotation of the drive shaft, and the winding roller is driven to rotate and wind. Cooperate with the first The block slides out completely from the slot, not only can the winding work be carried out accurately, but also can prevent the deviation of the ultra-fine denier yarn during winding, and at the same time, it can be more convenient to unload the material, thus speeding up the winding process work efficiency.

The invention discloses a network transformer pin automatic winding lead wire device and a winding method thereof, high automation level, greatly reducing the labor intensity of workers, and solves the problem of low winding efficiency of network transformer pins in the prior art, At the same time, the problem of unstable winding quality and high scrap rate is solved, and the purpose of increasingwinding speed, improving winding quality stability and reducing product scrap rate is realized, compared with the traditional process that manual operation depends on worker's skill and proficiency.
