The utility model provides a kind of mixing device of arterial blood collector, including rotating shaft and the mixing assembly being fixed in its outside, and the side plate of polygon is respectively arranged in the two sides of rotating shaft and multiple bearing plates are fixed on side plate, the detachable blood gas needle loading plate is equipped on the bearing plate, and multiple detachable blood gas needle mounting clips are equipped on the blood gas needle loading plate;The blood gas needle mounting clip is detachably set on the bearing plate.By blood gas needle mounting clip detachably set on blood gas needle loading plate, and blood gas needle loading plate itself also detachably install in the design of bearing plate, effectively solve the core pain point of poor versatility of traditional mixing device.

The utility model relates to homogenization mixing mechanism technical field, concretely is a kind of plant polyphenol and organic acid homogenization mixing mechanism, including mixing bin, the rotating joint of shaft is connected in mixing bin, the conical stirring head is fixedly installed in the lower end of shaft, flush subassembly is set to mixing bin outside, cleaning subassembly is set to mixing bin inside, the cleaning subassembly includes multiple movable L type scraper that sticks to the inner wall of mixing bin. In the utility model, through L type scraper, the inner wall of mixing bin is scraped to clean in real time, avoid the crystallization of organic acid attachment caused by temperature too low, make mixing bin more convenient to clean, through multiple baffle, the solution of lower layer is mixed by multiple shearing, accelerate mixing speed, simultaneously by the downward movement of pressing plate, push the solution of upper layer less downward, increase the heat exchange speed of solution upper layer and lower layer, avoid the inactivation of polyphenol and the stratification of mixed solution caused by the temperature of upper layer solution too high, improve mixing effect.

The embodiment of the invention provides a power module packaging structure, a power module, a motor controller and a vehicle, the power module packaging structure is used for being connected to a packaging chip substrate layer and a plastic packaging layer, and the power module packaging structure comprises a barrier layer and an enhancement layer; the blocking layer coats the periphery of the chip substrate layer and is used for isolating water vapor from permeating into the chip substrate layer; and the reinforcing layer coats the periphery of the barrier layer and is used for reinforcing the binding force between the plastic packaging layer and the chip substrate layer. External water vapor can be prevented from permeating into the chip substrate layer through the blocking layer, the water vapor is prevented from permeating into the chip substrate layer through the bonding layer made of the silane coupling agent, and the chip substrate layer is prevented from being oxidized and corroded easily to generate an oxidation separation layer. And the binding force between the plastic packaging layer of the packaging structure and the chip substrate layer is further enhanced through the enhancement layer, so that the plastic packaging layer has a better adhesive force enhancement effect on the chip substrate layer, and the condition that the plastic packaging layer and the chip substrate layer are easily layered under the condition of high junction temperature is avoided.

The utility model discloses a composite flame -retardant epoxy resin board belongs to epoxy resin board technical field, including board main part, the board main part includes glass fiber resin base, one side of glass fiber resin base is pasted with the reinforcing layer, the other side of reinforcing layer is pasted with main flame -retardant layer, the other side of main flame -retardant layer is pasted with insulating flame -retardant layer, and glass fiber resin base, reinforcing layer, main flame -retardant layer and insulating flame -retardant layer are penetrated and fastened with fastening rivet, the outer wall of glass fiber resin base, reinforcing layer, main flame -retardant layer, insulating flame -retardant layer and fastening rivet is wrapped with organic silicon high temperature resistant paint layer. Through the setting of multilayer composite flame -retardant structure, make the glass fiber resin board give consideration to high -efficient flame -retardant efficiency simultaneously, ensure its mechanical property, set up array type anchoring structure simultaneously, effectively avoid the multilayer composite structure of its delamination situation appears because of high temperature, improve its high temperature state board body's stability.

The utility model belongs to injection molding machine field, specifically is a kind of raw material mixing device for injection molding machine, including injection molding machine main part, the top of injection molding machine main part is fixedly connected with jar body, the top of jar body is fixedly installed with fixed frame, the inner chamber rotation of fixed frame is equipped with first rotation axis, and one end of first rotation axis enters the inside of jar body;By setting two feeding hoppers, guide frame and material distributing leaf, after adding material in feeding hopper, feeding hopper imports material into guide frame, material is guided by guide frame, and part of material falls on another guide frame by opening, so that material starts mixing on guide frame, and after separating from guide frame, material is dispersed by material distributing leaf, to carry out secondary mixing to material, then three times mixing of material is carried out by stirring frame, to effectively improve the mixing efficiency of material, simultaneously effectively avoid the situation that granular raw material stratifies, to ensure the quality of product.
