This utility model relates to the field of anti-tangling technology for nylon spinning winding, and discloses an anti-tangling nylon spinning winding device, including a winding box, and further including: a winding disc rotatably connected to the front side of the winding box; two take-up rollers rotatably connected to the front side of the winding disc for rotating and winding the nylon yarn; and a guiding mechanism disposed on the outer wall of the winding box for guiding the nylon yarn to be wound and wound onto the outer wall of the take-up rollers. This utility model guides the nylon yarn through multiple guide cylinders, ensuring that the nylon yarn maintains a straight path during winding, avoiding tangling and knotting. The guide rollers abut against the outer wall of the nylon yarn, and a return spring pushes the arc-shaped sleeve to move, further tightening the nylon yarn, ensuring stability during winding and effectively preventing tangling.

The utility model relates to the technical field of fertilizer conveying devices, and discloses a fertilizer conveying device of a chain type fertilizer smoothening machine, which comprises a chain type conveying belt, rotating shafts are rotatably connected to the interiors of the two ends of the chain type conveying belt, a supporting frame is rotatably connected to the surfaces of the rotating shafts, and an adjusting assembly is in threaded connection to the middle of the supporting frame. A supporting frame is slidably connected to the surface of the rotating shaft, two pushing assemblies are slidably connected to the bottom of the supporting frame, rotating rods are sleeved with the pushing assemblies, the adjusting assembly comprises a threaded rod in threaded connection to the middle of the supporting frame, and a rotating disc is fixedly connected to one end of the threaded rod. According to the fertilizer conveying device of the chain type fertilizer smoothening machine, by arranging the adjusting assembly, the effect of adjusting the tensioning degree of the chain type conveying belt is achieved, it is ensured that the chain type conveying belt is kept in a proper tensioning state in the running process, vibration and shaking are reduced, and therefore the conveying stability and accuracy are improved.

The utility model discloses a PET (polyethylene terephthalate) film conveying and positioning device for transfer printing of household appliance glass panels, which comprises a frame, a conveying unit, a deviation rectifying device and a tensioning unit, the conveying unit comprises transmission rods rotatably mounted on two sides of the frame, conveying rollers are fixedly mounted on the transmission rods on two sides, a driving component is arranged between the transmission rods on two sides, and the conveying rollers are fixedly mounted on the transmission rods on two sides. The number of the deviation rectifying devices is two, the two deviation rectifying devices are arranged between the conveying rollers on the two sides, and the tensioning unit is arranged between the deviation rectifying devices on the two sides. Through the synergistic effect of the conveying unit, the deviation correcting device and the tensioning unit, stable conveying and precise positioning of the PET film for transfer printing of the household appliance glass panel are achieved, through the synergistic effect, the conveying stability of the PET film is improved, the position accuracy and the tensioning degree suitability of the PET film in the conveying process are guaranteed, and the conveying efficiency of the PET film is improved. Therefore, the transfer printing quality and the production efficiency are remarkably improved, and the defective rate caused by unstable conveying, deviation or improper tensioning of the PET film is effectively reduced.

The utility model relates to rigging loom equipment technical field and disclose a kind of rigging loom device convenient to reel, comprising: loom body and base, the reel mechanism for quick reeling loom body, the tensioning mechanism for adjusting the tensioning degree of loom body and the guide mechanism for limiting the trend of loom body when reeling are respectively provided on the base.This rigging loom device convenient to reel, through the reeling of loom body by setting reel mechanism and guide mechanism, wherein reel motor is driven reel shaft and reel drum rotation by synchronous pulley group synchronous belt to reel, realize the automatic reeling of loom body, improve the reeling efficiency, reduce manual labor intensity, and before loom body is wound on reel drum, after the limiting guide of upper guide roller and lower guide roller, it can prevent the situation that loom body winding is disorderly and affects work efficiency, further improve the work efficiency of overall structure.
