The utility model discloses an anti-twisting yarn guide device, which belongs to the technical field of devices for composite material production, and comprises an inner ring and an outer ring, the outer ring is sleeved outside the inner ring, the inner ring is rotatably connected with the outer ring, the inner ring is provided with a yarn passing hole, two shaft sleeves are rotatably connected in the yarn passing hole, the axis of each shaft sleeve is perpendicular to the axis of the inner ring, and a yarn passes through the space between the two shaft sleeves; two limiting columns are fixedly connected to the outer side wall of the inner ring and symmetrically arranged, two limiting holes are formed in the side wall of the outer ring, the two limiting columns penetrate through the two limiting holes respectively, and when the inner ring rotates, the two limiting columns slide in the two limiting holes respectively. On the premise that yarn abrasion is not increased, the twisting angle of the yarn in the running process can be limited, and the yarn is prevented from being twisted or folded.

The utility model belongs to tooling cloth arrangement device technical field, concretely relates to tooling cloth arrangement device, including motor, be provided with gear shaft on the motor, the inside of gear shaft is provided with thread groove, the inside of thread groove is connected with screw rod through screw thread, the left -hand end fixed connection of screw rod has the rotary block, gear shaft outside contact has the connecting piece, the inside of connecting piece contacts screw rod, connecting piece and rotary block contact, the outside of connecting piece is provided with limit mechanism, the inside of motor is provided with heat dissipation mechanism. The utility model through design motor and gear shaft, start motor, motor drive gear shaft rotation, realize the action of cloth winding, and can satisfy automatic cloth arrangement, further prevent cloth edge to produce folding, prevent cloth service life to shorten.

This utility model relates to the field of tire forming equipment technology, specifically to a device for reducing the incidence of tire sidewall suspension buckling and folding. It includes two symmetrically arranged clamping assemblies, each comprising a mounting bracket. One end of the mounting bracket has a central shaft vertically mounted on it. A first ball bearing is fitted onto the central shaft, and a flexing arm roller is fitted onto the outer periphery of the first ball bearing. The mounting bracket has two flexing arms symmetrically arranged along its length, with the two flexing arms located on one side of the flexing arm roller. A plurality of second ball bearings are fitted onto the shafts of the two flexing arms. The device provided by this utility model for reducing the incidence of tire sidewall suspension buckling and folding can solve the problem of existing flexing arms easily causing tire sidewall suspension buckling and folding.

The utility model provides a kind of foldable guide rod device, including middle guide rod welding, and the left and right sides of middle guide rod welding are equipped with hose and side guide rod, and one end of hose is hinged with middle guide rod welding through first hinged shaft, and hose can rotate up and down relative to middle guide rod welding around first hinged shaft, and the other end of hose is hinged with side guide rod through second hinged shaft, and side guide rod can rotate up and down relative to hose around second hinged shaft;Side guide rod downside is also fixed with mounting support assembly.Adopting the utility model, by setting hose between middle guide rod welding and side guide rod, hose can be curved with the folding of cutting table, avoid hard contact and structural interference;At the same time, the hinged structure of hose two ends reliably releases deformation stress, avoids the folding situation of hose, guarantees the service life of hose.
