Crossed cloth wetting towel machine, including setting up in proper order along wet towel delivery direction's unwinding frame, turning to mechanism, front traction subassembly, folding mechanism, water spraying mechanism, cutting mechanism and output mechanism, water spraying mechanism's front and back both sides all are provided with a group of rear traction subassembly, two groups rear traction subassembly realize synchronous drive through drive subassembly, folding mechanism includes folding frame and is provided with several groups folding subassembly on folding frame, each group folding subassembly includes two folding base plates that are set up opposite up and down, two folding base plates between vertically are equipped with two folding plates, and the folding groove for wet towel is formed between two folding plates, the utility model discloses a progressive V-shaped folding groove that is formed by the vertically arranged folding plate realizes compact and accurate folding, and the double traction structure on both sides of the water spraying mechanism ensures stable conveying of the wet towel before and after adding liquid, and also has a draining function, the synchronous transmission of traction and output reduces the manufacturing cost, and ensures the operation synchronization of the whole line.

The utility model provides a tightener for electric power construction, which relates to the technical field of tighteners and comprises a support, a take-up roller is rotatably arranged between the front inner wall and the rear inner wall of the support, a steel rope is wound around the take-up roller, and one end of the steel rope is provided with a joint piece. The combined piece comprises a square block and clamping plates, one end of the square block is fixed to the steel rope, a through groove is formed in the square block, the two movable clamping plates are arranged in the through groove, and a two-way screw is rotationally arranged at one end of the square block and used for controlling the two clamping plates to move. According to the utility model, the two clamping plates clamp a cable at the same time, and force can be uniformly applied from two directions, so that the cable is stably fixed in the circular through groove, shaking and displacement of the cable are reduced, and the cable is stably clamped; and meanwhile, the two clamping plates are screwed through the two-way screw rod and are lifted up and down at the same time, it can be guaranteed that pressure borne by the cable in the circumferential direction is more uniform in the clamping process, and an insulating layer or an internal structure of the cable is prevented from being damaged.

This invention discloses a multi-stage drilling trajectory stabilizer, comprising an outer casing and an electric cylinder. An mounting cylinder is fixedly installed on the top of the outer casing, and an auxiliary stabilizing sleeve is fixedly installed inside the mounting cylinder. Two sliding grooves are formed inside the outer casing, and sliding rods are slidably installed inside each of the two sliding grooves. An extension connecting rod is threaded to the top of each sliding rod, and a connecting sleeve is fixedly installed on the top of each sliding rod. The invention employs a dual stabilizing structure with the auxiliary and main stabilizing sleeves working in tandem, guiding and constraining the drill rod during the drilling and deep hole machining stages respectively. This fundamentally ensures a straight drilling trajectory and precise hole positioning, significantly improving drilling accuracy and hole shape quality. The main stabilizing sleeve can move downwards in real time with the drilling depth, and a connector extends into the hole for auxiliary positioning, effectively solving the problems of drill rod wobbling and deflection during deep hole machining, reducing the risk of drill rod vibration and breakage, and extending the service life of the drill rod.

This utility model discloses a fabric pattern making and cutting machine for thermal down jackets, including a main body of the fabric cutting machine. Mounting brackets are fixedly installed on both sides of the main body. A pressure plate is installed on the top of each mounting bracket. Adjusting screws are rotatably installed on the top of each mounting bracket. The pressure plate is threaded onto the two adjusting screws. Second mounting brackets are fixedly installed on both sides of the main body of the fabric cutting machine. An electric push rod is fixedly installed on the top of each second mounting bracket. This utility model can flatten the fabric when it is fed in, ensuring normal fabric feeding while smoothing out uneven wrinkles on the fabric surface. This ensures straight and flat fabric edge cut lines, improves the accuracy of fabric pattern making, enhances the quality of down jacket pattern making, improves the aesthetics of the garment, reduces defects and rework, and increases the efficiency of down jacket production.
