This application discloses a precast concrete placement vibration device and system, including a base, a support seat, air springs, a mold locking unit, and a vibration motor. The support seat is located above the base, and its upper surface is a bearing plane for supporting the mold or mold table. The support seat is connected to the base at opposite ends via air springs, which enable the support seat to move vertically. The mold locking unit is fixedly connected to one side of the support seat and is configured to lock the mold or mold table onto the support seat. The lower part of the support seat has a motor mounting base, on which the vibration motor is mounted. The angle between the mounting surface of the motor mounting base and the bearing plane is greater than or equal to 0° and less than or equal to 60°. The precast concrete placement vibration device of this application has advantages such as high vibration efficiency and good vibration quality.

The utility model discloses a die flow channel structure, coating die and coating device, include: at least one cavity, at least one feed channel, multistage symmetry shunt structure, symmetry shunt structure includes at least one sub runner, and sub runner has sub runner feed port and two sub runner discharge port, and the sub runner feed port of symmetry shunt structure in first stage is communicated with feed channel, and all sub runner discharge ports of symmetry shunt structure in last stage are communicated with cavity, and two sub runner discharge ports of each sub runner are about the symmetry distribution of sub runner feed port of this sub runner, and each sub runner discharge port of symmetry shunt structure in same level is arranged at equal intervals. Through multistage symmetry shunt structure, and sub runner discharge port is about the symmetry distribution of feed port and is arranged at equal intervals, and it is ensured that each flow channel flow distribution is consistent, and the difference of edge and central region discharge amount is reduced significantly.

The utility model relates to a kind of low resistance rotary heating screw structure of modified plastic, including: outer tube, it is set at the inner cavity of modified plastic extruder, outer tube is conically arranged, and the top of outer tube is provided with feed pipe;Conical cylinder is rotationally arranged in the inside of outer tube, the outer peripheral wall of conical cylinder is wound with two spiral blades, one end of two spiral blades is provided with communicating pipe, communicating pipe and the inner cavity of conical cylinder are interconnected, and the inside of spiral blade is provided with flow channel.The utility model relates to the technical field of modified plastic extrusion screw.The low resistance rotary heating screw structure of the modified plastic, when material enters to the inside of outer tube through feed pipe, by larger pitch, and cooperate conical cylinder of conical arrangement, the rapid paving of material can be realized, make solid material quickly flatten, reduce the accumulation of solid material, avoid the friction between solid material to influence screw rotation, and then reduce the friction of screw.

The invention discloses a rapid fabric flattening device and flattening method, and relates to the technical field of sewing equipment. The spreading platform surface is horizontally arranged on the support, a plurality of vertical air suction holes are formed in the center area of the spreading platform surface, the axial direction of the vertical air suction holes is perpendicular to the spreading platform surface, a plurality of inclined air suction holes are formed in the periphery of the center area of the spreading platform surface, and a preset inclination angle is formed between the axial direction of the inclined air suction holes and the spreading platform surface; the air flow direction of the plurality of inclined air suction holes is diffused from the central area to the periphery; the air suction end of the air suction device is communicated with the vertical air suction hole and the inclined air suction hole, and the air suction device is used for providing negative pressure; the negative pressure provided by the air suction device generates vertical adsorption force on the fabric through the vertical air suction holes so as to achieve positioning, and inclined traction force with an outward horizontal component is generated through the inclined air suction holes so as to flatten the fabric. Various fabrics can be quickly and effectively flattened, and seamless connection with subsequent process equipment is facilitated.
