The utility model discloses a kind of wind pipe plate composite use roll press type gluing device, it is related to wind pipe plate processing technical field, including rack, the top of the rack is fixed with support plate, the top of the support plate is fixed with mounting bracket, the inner wall of the mounting bracket is rotatably connected with rotating rod, and one end of the rotating rod is installed with unwinding roller, the utility model has beneficial effect for: rack is as basic support structure, and it provides stable mounting platform for entire device, support plate is fixed in the top of rack, and mounting bracket and rotating rod, unwinding roller and the like components are installed on it, so that the unwinding operation of core plate can be orderly carried out, core plate is wound on unwinding roller, subsequent processing procedure is facilitated, the setting of three groups of first limiting roller can play good guiding and limiting effect to core plate, ensure that core plate keeps stable path during conveying process, avoid the situation of deviation, provide good prerequisite for subsequent gluing and composite procedure.

This invention relates to the field of shampoo and hair care products, and more particularly to a method and equipment for producing shampoo and hair care products containing Platycladus orientalis leaf extract. The equipment includes a housing; a pressure roller for crushing plant materials is mounted on a movable base; a perforated plate for carrying the plant materials is installed inside the housing; the perforated plate has several holes; a second moving drive component, a connecting frame, and sealing columns are also included; the second moving drive component is mounted on the housing; the connecting frame is connected to the driving end of the second moving drive component; several sealing columns are mounted on the connecting frame. This invention utilizes the sealing columns to completely block the holes, and in addition to sealing the perforated plate, the sealing columns form several protrusions on the material-carrying surface of the perforated plate. The protrusions of the sealing columns and the grooves on the pressure roller form a corresponding concave-convex structure, which enhances the crushing effect on the plant materials.

This utility model relates to the field of cable technology and provides a torsion-resistant cable, comprising: multiple conductors and a cross-shaped spacer, wherein the cross-shaped spacer is attached to the multiple conductors, a shielding layer is fixedly connected to the outer surface of the conductors, and a buffer layer is provided between the shielding layer and the cross-shaped spacer. It also includes: a reinforcing mesh, fixedly connected to the outer surface of the shielding layer; the multiple conductors are separated by the cross-shaped spacer to prevent them from tangling together and affecting the transmission of power signals; the shielding layer is fixedly connected to the outer surface of the conductors, and the shielding layer is made of copper foil, which has excellent conductivity and can effectively shield high-frequency electromagnetic interference; the buffer layer is provided between the shielding layer and the cross-shaped spacer, and the buffer layer is made of polystyrene foam, which has good shock absorption and cushioning performance, can absorb impact energy, and protect the internal conductors from damage; the reinforcing mesh can improve the flexibility of the cable body and prevent damage to the conductors.

This utility model relates to the field of soil testing technology and discloses a soil dilution device for soil testing, including a dilution cylinder, a filter plate, and a rolling roller. A vent pipe is fixedly connected to one side of the stirring pipe, and an air intake mechanism is connected to the top of the fixed pipe. Actuating pipes are connected at equal intervals to the bottom of the vent pipe. Two actuating balls are fixedly connected to the center of the bottom of the filter plate, and the bottom of the actuating balls abuts against an arc-shaped plate. One side of the arc-shaped plate is connected to the stirring pipe. The rolling roller abuts against the top surface of the filter plate. A spraying mechanism is connected to the left side of the dilution cylinder. This utility model, through the coordinated use of the air intake mechanism, actuating pipes, and rolling roller, allows the air intake mechanism to heat the crushed and screened soil through the actuating pipes during soil dilution and screening, thereby reducing the moisture content of the soil. Then, the rolling roller's compaction improves the efficiency of soil crushing and screening, ensuring the effectiveness of soil dilution.
