The invention discloses a flat electro brush plating experiment platform, comprising a lifting frame, a brush plating device and a plating solution delivery device, wherein the brush plating device is located above a workpiece, is arranged on the lifting frame and is driven to move up and down by the lifting frame; the brush-plating device comprises a driving band and a plurality of brush plating pens; the plurality of brush plating pens are evenly distributed on the outer surface of the driving band; the driving band drives the brush plating pens which are arranged on the driving band to move towards the same direction; a pressure sensor is arranged on each brush plating pen; and the plating solution delivery device is used for conveying a plating solution to the brush plating pens. According to the flat electro brush plating experiment platform disclosed by the invention, the brush plating pens are evenly distributed on the outer surface of the driving band; the driving band drives the brush plating pens arranged on the driving band to move together towards the same direction; the movement direction of the brush plating pens is fixed, so that brush plating at a constant speed can be reached. A support plate is arranged on the inner surface in the middle of the lower part of the driving band, so that the driving band is prevented from jumping up and down in the driving process to affect the contact of a brush head and the workpiece, so as to cause uneven brush plating.

The invention relates to the technical field of card holders for POS machines, and discloses a dustproof and waterproof card holder, comprising an upper cover and a lower casing, the upper cover and the lower casing are fastened and sealed, and one end thereof is an open end; the bottom surface of the lower casing It is closed and embedded with multiple terminals. The upper surface of the terminal is exposed on the upper surface of the lower case, and the other end of the terminal is exposed through the bottom of the lower case. When the card is inserted into the card holder through the open end , the chip of the card is in contact with the terminals. Compared with the prior art, the present invention arranges the terminals and switches in the upper cover and the lower housing, and provides three-side seals and one side opening, which can prevent dust and prevent water from penetrating into the card holder. Extend the service life of the POS machine.

The invention relates to a router with a dust-proof function and good heat dissipation effect, which includes a main body, two antennas, two brackets and several wiring ports, and also includes a dredging mechanism and several dust-proof mechanisms. The dredging mechanism includes a support plate, a dredging assembly and several dredging rods, the dredging assembly includes a first motor, an eccentric wheel, a vibrating plate, a spring, a sleeve and a vibrating rod, and the dust-proof mechanism includes a second motor, two transmission assemblies and two overturning assemblies. The flipping assembly described above includes a rotating shaft, a flipping plate and two collars. The router with a dust-proof function and a good heat dissipation effect can perform dust-proof work on the wiring port when the wiring port is idle to prevent dust from entering the wiring port through the dust-proof mechanism. , affect the contact between the network cable connector and the wiring port. Through the dredging mechanism, the vent can be dedusted to prevent dust from blocking the vent and affecting the circulation of the air. The dredging mechanism improves the heat dissipation effect.

The invention discloses a combined type efficient traditional Chinese medicine grinder. The combined type efficient traditional Chinese medicine grinder comprises a mounting groove, a grinding block,a grinding disc, a material collection groove, a base and a top plate, wherein a separation plate is fixed at the middle position in the base; first through holes are uniformly formed in the separation plate; bulges are uniformly distributed at the top of the separation plate; the mounting groove is formed in the base above the separation plate; a feeding opening is formed in one side of the top end of an outer side wall of the base at the position of the mounting groove; one end of the feeding opening extends to the top of the base; and the other end of the feeding opening extends to an innerside wall of the base at the position of the mounting groove. According to the combined type efficient traditional Chinese medicine grinder disclosed by the invention, a discharging hopper is fixed in the base and the base is hinged with a transparent side cover; a rubber vibration absorption cushion is mounted at the bottom of the base; ground traditional Chinese medicines can be conveniently collected and the sealing performance of the material collection groove is increased, so that dust pollution is avoided and the ground traditional Chinese medicines are prevented from being splashed through an external force; and the stability of placing the base is increased, slipping resistance is realized and noises generated in a grinding process are reduced.

The invention relates to the field of carton processing equipment, in particular to an environmentally-friendly carton production device. The environmentally-friendly carton production device comprises a base, a shaking structure, a supporting structure, a binding structure, guide structures and limiting structures. The supporting structure which is used for storing and supporting cartons is arranged on the base and connected to the shaking structure which is located inside the base. The supporting structure and the base are connected in a rotating mode through the shaking structure, then thesupporting structure is conveniently driven by the shaking structure to conduct reciprocating shaking movement, the side edges of the cartons can conveniently align, and the stress can be more uniformwhen the cartons are bound. The two limiting structures are arranged on the supporting structure in the mode of being symmetrical about the base, due to the arrangement of the limiting structure, theother two side edges of each carton are conveniently limited, the cartons can be stacked more orderly, the cartons can be bound more regularly, and stacking operation and storage of the cartons in the later period are facilitated. The guide structures are arranged on the limiting structures, the cartons are conveniently guided by the guide structures, the cartons can more conveniently enter the space between the two limiting structures, and the carton storage effect can be better.

The invention discloses conductive slurry for a battery pole piece, the battery pole piece and a battery, the conductive slurry for the battery pole piece is composed of a conductive agent, a solvent and fine bubbles, and the conductive agent comprises graphene and carbon nanotubes; the particle size of the micro-bubbles is less than 100 microns, and the concentration of the micro-bubbles is greater than 106 / ml; and the mass content of the conductive agent is between 0.5 wt.% and 8 wt.%. When the obtained conductive paste is used in the actual battery electrode preparation process, the conductive paste containing the micro-bubbles is very easy to store and does not generate precipitates after being placed for several months, and the requirement that the conductive paste needs to be placed for a period of time in the storage and transportation process is met. The problem that the existing graphene dispersion liquid can be used only after dispersion treatment is avoided, and the graphene dispersion liquid can be directly used for preparing the electrode of the battery.
