The utility model relates to the field of warping machines, in particular to an adjustable feeding mechanism of a warping machine. The technical problems that in the using process of a discharging mechanism, due to the fact that warps are prone to bending in the discharging process, the uniformity of the warps in the discharging process cannot be guaranteed, and due to the fact that most of the warps are of a fixed structure, the height of a collecting roller cannot be adjusted are solved. According to the technical scheme, the adjustable warping machine discharging mechanism comprises a supporting bottom plate; the device further comprises a discharging assembly and a collecting assembly. By arranging the discharging assembly, a wire rod passes through the interior of the warp groove, the uniformity of the warp is ensured, the leveling roller can press and level the warp on the warp guide roller through the gravity of the leveling roller, a first telescopic spring can drive a first limiting sliding block to conduct elastic adjustment, the leveling roller is adjusted to the proper tension, and therefore the leveling effect is improved. The warp is prevented from being bent in the discharging process, then the collecting roller is rapidly and stably installed through the collecting assembly, and the height of the collecting roller is adjusted.

The invention discloses a cloth pressing device for weaving, and relates to the field of textile equipment.The cloth pressing device for weaving comprises two supporting machine plates, the inner sides of the two supporting machine plates are fixedly connected with a flattening base plate, and textile wefts and textile warps which are woven into cloth are arranged above the flattening base plate; clamping and stretching assemblies used for straightening textile wefts on cloth are symmetrically arranged on the outer sides of the two supporting machine plates, a flattening and lifting assembly used for flattening the cloth is arranged on the top of the flattening base plate, and a tightening and storing assembly used for straightening textile warps is arranged below the flattening base plate. According to the textile weft stretching device, through the stretching effect of the clamping and stretching assembly on the textile weft, the textile weft in the woven cloth is straightened, then wrinkles are prevented from occurring when the subsequent textile weft is flattened, and the situation that the woven cloth deforms due to compression of the textile weft in the subsequent process is prevented.

The utility model discloses a pipe laying and paying-off device for a water conservancy project, and relates to the technical field of water conservancy projects. The pay-off device comprises a movable installation bottom plate and a pay-off wheel, the top end of the movable installation bottom plate is symmetrically and fixedly connected with installation plates, the outer surfaces of the installation plates are fixedly connected with L-shaped plates, the outer surfaces of the L-shaped plates are fixedly connected with first motors, one ends of output shafts of the first motors are fixedly connected with first gears, and the other ends of the output shafts of the first motors are fixedly connected with second gears. A limiting and fixing assembly is arranged between the outer surface of the mounting plate and the outer end of the pay-off wheel, a U-shaped plate is slidably connected to the top end of the movable mounting bottom plate, an adjusting and limiting assembly is arranged on the outer surface of the U-shaped plate and comprises a rotating wheel, and a second motor is fixedly connected to the outer surface of the U-shaped plate. One end of an output shaft of the second motor is fixedly connected with a second screw rod; the cable pay-off device solves the problems that the position of a cable is easy to deviate or bend and the pay-off wheel is difficult to replace quickly.
