A strap-reel frame includes a frame body having a shaft horizontally provided thereon for fitting an inner disc and an outer disc which respectively have the central portion formed with a columnar projection for fitting the opposite ends of a strap reel. A strap-clamping rod is provided above the shaft of the frame body, having a strap-clamping unit assembled thereon. A strap-passing gap can be formed for a strap to pass therethrough after the press member of the strap-clamping unit is pressed inward and the strap in the strap-passing gap can be clamped in position after the press member is released. In addition, two reel end connectors with a comparatively large diameter can be respectively covered over the two columnar projections and then fixed on the inner and the outer disc for fitting a strap reel.

A printer takes up slack in media while suppressing excessive rewinding, and can check the movement of a movable member that moves following change in tension on the media. The printer drives the supply motor in a first operating mode in a slack removal operation that rewinds the recording paper (media) onto a paper roll 2, and stops driving the supply motor when the tension lever (movable member) moves from a slack-side first position toward a second position. In the movement checking operation, the supply motor is driven in a second operating mode with greater output than the first operating mode, rewinds the recording paper on the paper roll, and sets the tension lever to the second position.

The present invention relates to a container intended for receiving a strip that is studded with balance weights (4) and forms a belt (8) and intended for dispensing the same to a transporting and cutting-to-length mechanism. The container is formed as a casing (2) that is closed substantially on all sides and has two spaced-apart side walls, which receive the belt roller (6) between them, and also a peripheral wall (14), which connects the side walls to one another and has a dispensing opening (16) for the belt (8) to pass through. On the inner side of at least one of the side walls (10, 12) there is formed at least one restrainer (32, 34) that lies against the belt or the belt roller and spreads at an angle to prevent a return movement of the belt or the belt roller.

The invention provides a pipe spraying equipment, which relates to the field of pipe processing. The pipeline spraying equipment includes an injection molding machine, a spraying mechanism, a grinding mechanism and a guide plate. A support is provided on the outer wall of the bottom end of the injection molding machine, and a discharge port is provided on one end of the injection molding machine. The outer wall is provided with a spraying mechanism, the inner wall of the spraying mechanism is provided with annularly distributed nozzles, and the inner wall of the nozzles is provided with a rotating shaft, the output shaft of the rotating shaft is connected to a rotating motor through a coupling, and the outer wall of the rotating shaft is provided with Rotating roller, the outer wall of the rotating roller is connected with the grinding mechanism box, the inner wall of the nozzle close to the rotating roller is connected with the guide plate, and the outer wall of the bottom end of the nozzle is provided with a nozzle. When the extrusion layer is in contact with the nozzle, the grinding block on the extrusion layer can pulverize smaller agglomerated particles and vibrate a small part of the chemical powder stuck in the pipeline spraying equipment. Shedding, to achieve the effect of self-cleaning.

The invention belongs to the technical field of nuclear fuel reprocessing and discloses an oxidizing valence-adjusting equipment for oxidizing Pu (III) to Pu (IV). The equipment mainly comprises an oxidizing tower, a feed liquid receiving tank and a NOX storage tank, wherein a feed liquid outlet is formed at the upper end of the oxidizing tower, a Pu (III) feed liquid inlet and a NOX feed inlet are formed at the lower end, and the feed liquid outlets at the upper parts of the feed liquid receiving tank and the oxidizing tower are connected by virtue of a pipeline; the main body of the oxidizing tower and packing in the tower are both radiation-resistant and nitric acid corrosion-resistant materials; a heating device is arranged on the outer tower wall of the oxidizing tower; the Pu (III) feed liquid enters the oxidizing tower from the Pu (III) feed liquid inlet at the lower part of the oxidizing tower; NOX gas provided by the NOX storage tank enters into the oxidizing tower from the NOX feed inlet at the lower part of the oxidizing tower separately or together with carrier gas; the valence-adjusted feed liquid enters the feed liquid receiving tank from the feed liquid outlet at the upper part of the oxidizing tower. The equipment is large in processing scale, high in NOx utilization ratio, safe and stable in valence-adjusting process and low in processing burden of nitric oxide tail gas.
