The invention discloses an arrangement line conveying belt tensioning mechanism. The mechanism comprises a conveying belt, a driving roller and a tensioning roller; end rollers are mounted at two ends of the conveying belt; the conveying belt is bypassed through the end rollers at two ends and the driving roller; the lower part of the conveying belt is butted against the tensioning roller; square shafts at two ends of the tensioning roller are connected with swing arms; the swing arms are connected with tensioning screw rods; a side plate is fixed on one side of the conveying belt, and is rotationally connected with a tensioning plate; notches are formed in the end parts of the tensioning plate; and the tensioning screw rods are inserted in the notches. The arrangement line conveying belt tensioning mechanism can finish elastic adjustment of the conveying belt without dismounting any part, and is simple in operation and convenient to use.

The invention relates to the technical field related to the stranding machine, and discloses a tubular stranding machine for steel wire rope production, including a base of the tubular stranding machine and a supporting frame located on the base of the tubular stranding machine, the supporting frame The tension adjustment mechanism and the second traction assembly are respectively arranged on the top, and the second traction assembly includes a moving plate, a pressing block, a rope closing block and a vertical plate, and the vertical plate and the base of the tubular stranding machine pass through a third The sliding block is connected, the moving plate is arranged on the support frame, the moving plate is connected with the mounting plate through an electric push rod, and the mounting plate is slidably installed on the vertical plate through the sliding plate, the The rope closing block is rotatably connected to the vertical plate, and the pressing block is installed and fixed on the mounting plate; the present invention effectively solves the tension adjustment problem of the steel wire rope through the cooperation of the provided tension adjustment mechanism and the second traction assembly .

The invention belongs to the technical field of glass bottle production, and provides a flat-push automatic depalletizing device, which includes a depalletizing machine and a bottle conveying machine; The supporting plate driven by the first driving device is slid and installed in the vertical direction, and the bottle pushing rack driven by the second driving device is slid and installed on the top of the unstacking frame along the horizontal direction. The position is fixed and the baffle plate is installed, and the two sides of the unstacking frame are respectively equipped with clamping mechanisms; the bottle conveyor includes a conveyor frame, and the conveyor frame is wound with a conveyor plate chain driven by a third drive device. One end of the rack is positioned against the baffle, flush with the top of the baffle. The horizontal pushing depalletizing method adopted by the present invention can directly push the entire layer of glass bottles to the bottle conveying machine for transportation. Compared with the traditional manual depalletizing method, it not only saves labor costs, but also greatly reduces labor intensity, and the work Efficiency is greatly improved.

The invention discloses a synchronous belt tensioning device. The synchronous belt tensioning device is formed by two clamping blocks, and the two clamping blocks are connected through bolts; the clamping blocks comprise first clamping plates and second clamping plates; the first clamping plates are in T shapes, bolt adjusting holes are formed in the two ends of transverse parts of the first clamping plates and used for containing the bolts; a plurality of installing holes are formed in the two ends of longitudinal parts of the first clamping plates respectively, the first clamping plates are fixedly connected with a carrying table through the installing holes, grooves for containing a synchronous belt are formed in the middles close to the side faces of the second clamping plates, and a plurality of first connecting holes are also formed in the two ends of the side faces respectively; a plurality of tooth grooves for containing synchronous-belt racks are arranged at the portions, close to the side faces of the first clamping plates, of the second clamping plates respectively, a plurality of second connecting holes are also formed in the two ends of the second clamping plates respectively and correspond to the first connecting holes. By means of the synchronous belt tensioning device, tensioning adjusting of the synchronous belt installed behind a lifting machine can be achieved, and tensioning adjusting of the synchronous belt installed after a lifting machine can also be achieved.

The invention discloses a tensioning tool for a net of a filter plate. The tensioning tool is characterized in that each tensioning base adopts a jaw structure with one end fixed and the other end opened, tensioning bolts are horizontally arranged at the fixed ends of the tensioning bases, compression bolts are vertically arranged at the open ends of the tensioning bases, pressing plates are arranged at the tail ends of the compression bolts, and the compression bolts and the pressing plates are symmetrically arranged on the upper sides and the lower sides of the open ends of the tensioning bases. The tensioning tool is simple in structure, and flexible and convenient to use, can uniformly distribute a compression force by use of the pressing plate, avoids crushing the net and improves the friction by use of gaskets, and can realize efficient and high-quality completion of net tensioning through performing tensioning adjustment on the filter net during assembly of the net of the filter plate, thereby greatly improving the working efficiency and the yield and effectively prolonging the service life of the filter net.
