The invention discloses a device for printing characters on a draught beer barrel. The device comprises a machine frame, a hydraulic push device, a beer barrel outer side character printing device, a beer barrel inner side character printing device, a beer barrel drive mechanism and a plurality of character die assemblies, wherein the hydraulic push device, the beer barrel outer side character printing device, the beer barrel inner side character printing device, the beer barrel drive mechanism and the character die assemblies are installed on the machine frame. Each character die assembly comprises a male die and a female die, wherein the male die and the female die are used in cooperation for forming a single character through impressing. The beer barrel outer side character printing device, the beer barrel inner side character printing device and the beer barrel drive mechanism can all be independently operated. The beer barrel outer side character printing device and the beer barrel inner side character printing device can automatically find the corresponding female dies and the corresponding male dies according to impressed content and send the corresponding female dies and the corresponding male dies to impressing positions. The beer barrel drive mechanism can automatically rotate a beer barrel to the appropriate angle according to the impressed content. Therefore, operation is quite convenient, impressing is attractive, efficiency is high, and a great convenient effect is achieved for engraving and printing of concave-convex series numbers.

A fully automatic oyster crushing processing device, comprising a cylinder body, the top surface of the cylinder body is open, and several feeding holes are opened on the bottom surface of the cylinder body, all of which are connected to the inside of the cylinder body, and the feeding holes are evenly distributed in the cylinder body , the bottom surface of the cylinder body is fixedly connected to the top surface of the conical shell, the top surface and the bottom surface of the conical shell are both open, and the feeding holes are all connected with the inside of the conical shell, the area of ​​the top surface of the conical shell is larger than the area of ​​the bottom surface, and the conical shell The bottom surface of the shell is fixedly connected to the top surface of the stick box, both the top surface and the bottom surface of the stick box are open, and the stick box communicates with the inside of the conical shell. The invention can successively realize the crushing and crushing of oyster shells into powder, shorten the processing time of oyster shells, improve the processing efficiency, and limit the moving range of oyster shells by the briquetting, so as to prevent the oyster shells from being scattered and moving when the cone thorns move down, which cannot be effectively processed. Crushing, and the oyster shells are broken through the two working states of the cone, which is more uniform than the traditional crushing mode.

The 24 split nozzles (13a~13x) divided from the nozzle (13) are divided into: the first division consisting of the segmented nozzles (13o, 13p, 13r, 13s, 13u, 13v, 13x and 13m) at the corners Nozzle group; The second divided nozzle group consisting of the divided nozzles (13n, 13q, 13t, 13w) located in the outer periphery; The third divided nozzle group composed of the divided nozzles (13a-13d) located near the center; The flow rate of the processing gas supplied to each divided showerhead group can be independently controlled in the fourth divided showerhead group composed of the divided showerhead groups 13e to 13l sandwiched between the three divided showerhead groups and the first divided showerhead group or the second divided showerhead group.

The invention discloses an adaptive dual-mode blocking collision-prevention method. In the method, the number of immigratory tags and the number of resident tags in a frame are recorded respectively, and the residence rate of the frame is calculated; and based on the residence rate ps, two operating modes are combined to avoid collisions among the resident tags and simultaneously reduce the collisions between the resident tags and the immigratory tags. The method has the characteristics of high identification speed and fewer idle time slots, and the performance of a system is greatly improved.

A method for preparing a carbon nanotube / nitrogen-doped modified fiber composite material, using low-cost ceramic powder waste as a matrix raw material and supplemented with a dual-phase fiber body as a reinforcement, the source of raw materials is cheaper, environmentally friendly and It meets the requirements of green industrialization and indirectly relieves the pressure on environmental governance. According to the structural characteristics of the three-dimensional fiber body, the present invention creates a composite method of "two-phase complementarity". By introducing low-cost reagents such as cinnamic amide and ethylene glycol monomethyl ether, the surface of the fiber and the precursor solution are modified and filled to improve the The interfacial bonding force and dispersion performance between different fibers have been improved, and the lamination and compounding of aluminum silicate fiber cloth with high melting point and good high temperature resistance have been realized, which has effectively avoided the single mechanical defect of two-dimensional fiber cloth, and constructed a fabric with A three-dimensional fiber composite system of "dual-phase fiber-resin-cheap matrix" with excellent mechanical properties.
