The invention discloses an automatic feeding machine of a centerless grinding machine and belongs to auxiliary equipment of centerless grinding machines. A transverse conveying device comprises a base, a motor, a first shaft roller and a second shaft roller. The first shaft roller and the second shaft roller are arranged side by side and spaced from each other by a certain distance, so that a transverse conveying channel is formed. The vertical plant where the axis of the first shaft roller is located is parallel to the vertical plane where the axis of the second shaft roller is located. The transverse plane where the axis of the first shaft roller is located is not parallel to the transverse plane where the axis of the second shaft roller is located. A shaft roller spacing adjustment mechanism is arranged on the base. The two shaft rollers are driven by a motor through a transmission mechanism to rotate in the same direction. A material guiding device is located at the left inlet end of a transverse conveying channel and comprises a rolling way and an arc-shaped sliding way. An inlet of the arc-shaped sliding way is higher than an outlet of the arc-shaped sliding way. The arc-shaped sliding way is fixed to the base, and the inlet of the arc-shaped sliding way is connected to an outlet of the rolling way. When a workpiece slides downwards on the arc-shaped sliding way, the axis of the workpiece changes gradually; a workpiece direction changing mechanism is arranged between an inlet of the transverse conveying channel and the outlet of the arc-shaped sliding way, and thus directional conveying of the workpiece is achieved. By the adoption of the automatic feeding machine of the centerless grinding machine, automatic feeding of the centerless grinding machine is achieved.

The invention discloses an automatic cable transmission system, which includes a general controller, a cable reel, an automatic portable cable transmission robot, a metal rope sheath, a steel wire rope, a synchronous positioning traction device, a cable automatic lifting and laying device and a bracket, and the cable is automatically lifted and lowered. A cable reel is installed on the laying device, and a bracket is placed on the side of the automatic cable lifting and laying device, and several automatic portable cable transmission robots and a synchronous positioning traction device are fixed on the bracket in turn. There is a pay-off metal rope cover connected to the top, and the pay-off metal rope cover is connected with the cable wound on the cable reel. The cable automatic lifting and laying device, the automatic portable cable transmission robot, and the synchronous positioning traction device are respectively connected with the master controller. The invention realizes the fully automatic operation of the whole cable laying process, saves time and effort, has extremely high laying efficiency and low cost.

The invention discloses a glass magnetic piston pump. The invention comprises a glass part and an electromagnetic driving part. The glass part: a glass piston is installed in the glass pump body, a magnetic core is fixed in the glass piston, and the left end of the glass pump body is connected to a glass combined unidirectional pump body. The glass grinding port on the valve, the right end of the glass pump body is connected with the glass interface of the glass combined check valve; the glass pump body passes through the first electromagnetic coil and the second electromagnetic coil of the electromagnetic drive part. The invention is used to drive gas circulation, has good air tightness, is easy to connect with glass devices, and can operate under relatively high negative pressure.

The invention discloses a broccoli differential sorting and secondary uniform stripping and slicing device and method. An existing machine is not suitable for secondary stripping and slicing of broccoli. The device comprises a differential circular belt, two screw rods, a partition board conveyor belt, an inclined slideway and a disc cutter, wherein the inclined slideway is positioned below the partition board conveyor belt. The method comprises the following steps that two differential circular belts convey and sort broccolis in a differential manner, after sorting, the longest sides of broccolis falling down between the two screw rods rotate to be parallel with the axes of the screw rods under the rotating action of the two screw rods with opposite spirals, and the broccolis fall down between two transverse partition boards adjacent to the partition board conveyor belt; when being conveyed to a bevel edge position, the broccolis enter the inclined slideway; and the disc cutter carries out secondary stripping and slicing on the broccolis. According to the device, the two differential circular belts are utilized to automatically sort broccolis; the two screw rods are utilized to automatically adjust the orientation of broccolis; the transverse partition board of the partition board conveyor belt keeps the orientation of broccolis; and the inclined slideway with a fillet enablesthe broccolis to be in the middle of the inclined slideway so as to improve the stripping and slicing uniformity.

The invention discloses a targeted pharmaceutical composition loaded with amphotericin B and doxorubicin and application thereof, belonging to the field of medicine and pharmacy. The present invention proposes a novel pharmaceutical composition for the treatment of leishmaniasis. Two drugs, amphotericin B and doxorubicin with fluorescent tracer, are simultaneously loaded on a pH-responsive drug with good biological safety. A pharmaceutical composition is formed in a carrier material, wherein the carrier material is composed of a hydrophilic mannose residue that actively targets macrophages, a β-cyclodextrin, and a hydrophobic propionyl group. The biological safety (cytotoxicity, hemolytic toxicity) of the pharmaceutical composition of the present invention is better, stability, pH response drug release, targeting ability and therapeutic efficiency have all been verified in the cell model, realized amphotericin B at the same time The synergistic effect with doxorubicin greatly reduces the dosage of drugs, reduces side effects and economic burden of patients, and is expected to play a huge role in clinical application.
