An image forming apparatus transfers a toner image formed on a photoconductor drum onto a sheet-like recording member while the sheet-like recording member is transported and attracted to a transfer belt, and comprises a jam handling control unit for detecting a transport fault of the sheet-like recording member, and for stopping the transport operation when the transport fault is detected. When the transport fault is detected in a section other than a fixing section, the jam handling control unit first causes the transport operation of the fixing section, and thereafter causes the transfer belt and the transport operation on the upstream side thereof to stop, and any sheet-like recording member remaining on the transfer belt so that the transport mechanism on the upstream side thereof is transported and stopped at the position spanning between the area of the fixing section and the area of the transfer belt.

A method for improving the grinding efficiency of permanent magnet ferrite calcined material. The method of the invention is to add ferric chloride or ferrous chloride to the calcined material before wet grinding, and then wet grind to obtain slurry. During the grinding process of permanent magnet ferrite calcined powder, due to the gradual refinement of the powder particles, the specific surface area and surface energy of the particles increase, the viscosity of the slurry increases, and the fluidity becomes poor, resulting in a decrease in grinding efficiency. The ferric chloride or ferrous chloride added by the method of the present invention can be adsorbed on the surface of the slurry particles during the grinding process, significantly reducing the surface energy of the slurry particles, overcoming the attraction between the particles, reducing the crushing resistance, and improving the slurry particle size. Fluidity, thereby improving grinding efficiency.

The invention discloses a motor stator-rotor assembling device. The motor stator-rotor assembling device comprises a bracket, a tapered tool and an adjusting device, wherein the bracket comprises a frame body and a mounting plate fixed on the frame body; the tapered tool comprises a guide post, and a first conical block and a second conical block which are matched with each other through conical surfaces; the adjusting device comprises an adjusting block and a threaded rod; a stator of a motor is fixed on the mounting plate; the first conical block is used for being fixed on an end face of a revolving shaft at one end of a rotor of the motor; the second conical block is fixed on the guide post; the mounting plate is provided with a through hole being in alignment with a rotor mounting position inside the stator; the guide post passes through the through hole; the adjusting device is arranged on the frame body, positioned below the mounting plate, and used for adjusting the obliqueness of the guide post; the adjusting block is in a threaded connection with the threaded rod; the adjusting block is in contact with a side wall of the guide post; and the threaded rod is in a threaded connection with the frame body. Through adoption of the motor stator-rotor assembling device provided by the invention, stable centering is realized in a stator-rotor assembling process, and attraction between the stator and the rotor is reduced.

The invention discloses a convenient and clean reagent bottle for agricultural product detection, which comprises a bottle body, a bottle cap whose size matches the bottle mouth is connected to the bottle mouth, and a first storage tank is opened in the bottle cap. A liquid chamber, a tapered liquid flow channel is provided on the first liquid storage chamber, and a second liquid storage chamber is connected above the liquid flow channel, and a pressure guide plate is fixedly connected to the second liquid storage chamber, so A pressure block is fixedly connected to the top of the pressure guide plate and the pressure block is slidably connected to the bottle cap. The top of the first liquid storage chamber is provided with a slide plate whose size matches the first liquid storage chamber. The first liquid storage chamber There are multiple liquid inlet channels respectively opened at the bottom. The utility model has the advantages that the expandability of the air bag is used to expand the inner wall of the bottle to generate a relatively large pressure, so as to realize the cleaning of the inner wall of the reagent bottle.
