The application relates to the technical field of metering, and discloses a metering device, an eye drainage device and a method, which comprise a metering main body, a first cavity and a second cavity are arranged in the metering main body, the first cavity is provided with a drainage inlet, the first cavity and the second cavity are communicated through a communicating pipe, the communicating pipe comprises a rigid section and a hose section, the rigid section is communicated with the first cavity, the hose section is communicated with the second cavity, a piston block and a peristaltic driving unit are further arranged, the piston block is movably arranged in the rigid section, the hose section is arranged in the peristaltic driving unit, the first cavity is filled with a first medium, the second cavity is filled with a second medium, the peristaltic driving unit can drive the second medium in the hose section to be conveyed so as to move the piston block, the piston block drives the second medium to flow so as to drain the drainage inlet, and the second cavity is provided with a metering scale for metering. Through the above scheme, the problem that the drainage speed and the drainage volume are not accurately controlled in the drainage process in the prior art is solved.

The utility model discloses an edge sealing treatment device for leather processing relates to leather processing technical field. This edge sealing treatment device for leather processing, including bottom plate, is provided with trimming mechanism and conveying mechanism at bottom plate top, trimming mechanism includes trimming part and pressure part, trimming part includes moving frame and cutting knife, and pressure part includes extruding frame and two extruding rollers, the fixed plate is fixedly arranged on the outer wall of bottom plate, and the technical effect is that the pressure part in trimming mechanism is composed of extruding frame, extruding roller, spring and damper, and the spring is initially in the extension state, can continuously provide stable pressure for extruding roller, and the buffer effect of damper is matched, can effectively prevent leather from deviating and wrinkling in the cutting process, guarantees cutting accuracy and stability, and builds solid foundation for subsequent edge sealing process, and through rotating first threaded rod, moving frame can be driven along the limiting rod sliding, and the relative position of cutting knife and leather edge is adjusted flexibly.

The utility model belongs to the field of wire and cable manufacturing equipment, and particularly relates to a high-speed constant-tension communication wire pair twister, which comprises a wire coil driven to rotate, a twisting bow and a tension adjusting device, the tension adjusting device is arranged between the twisting bow and a wire guiding mechanism, and the tension adjusting device comprises a tension sensor and a tension buffer. The tension buffer comprises a mounting base, a first guide wheel, a guide rail, a tension spring and a supporting rod, the two ends of the tension spring are connected with the supporting rod and the sliding block respectively, the sliding block abuts against the inner side face of one frame plate under the action of the tension spring, the tension sensor comprises a second guide wheel and a pressure sensor, and a rotating shaft of the second guide wheel is parallel to a rotating shaft of the first guide wheel. When the pair twister works, a twisted cable sequentially passes through the first guide wheel and the second guide wheel, then enters the wire guiding mechanism and is finally wound on the wire coil, and the pair twister has the advantages of being high in working efficiency, good in twisting quality and easy to operate.
