The invention discloses a three-dimensional microchannel and pulsating flow cooling device, which relates to the technical field of radiators, and specifically relates to a new three-dimensional microchannel radiator using pulsating or intermittent fluid to dissipate heat and its 3D printing manufacturing method. The heat dissipation device includes a radiator, a pulsating pump, a cooler, and a connecting pipe; the radiator is closely attached to the heat source, and the radiator, the pulsating pump, and the cooler are connected in series through the connecting pipe, and the radiator includes: a liquid injection port , the bottom heat dissipation structure, the middle layer heat dissipation structure, the top layer heat dissipation structure, and the liquid outlet. The bottom heat dissipation structure, the middle layer heat dissipation structure, and the top layer heat dissipation structure are stacked in sequence, which has a good heat dissipation effect and is produced as one by 3D printing. After installation, the heat dissipation effect is further improved.

The invention provides a digital printing machine for ready-made clothes and a method for printing the ready-made clothes. According to the digital printing machine for the ready-made clothes and the method for printing the ready-made clothes, a screen printing function and an inkjet printing function are combined. A screen printing machine, an inkjet printing machine and a worktable mechanism are installed on a main rack. The ready-made clothes are printed through the inkjet printing machine in an inkjet printing area. The ready-made clothes are printed through the screen printing machine in a screen printing area. The screen printing machine and the inkjet printing machine are arranged on the main rack in a front-and-back manner in the conveying direction of the ready-made clothes. A movable mechanism is connected with worktables and can drive the worktables to move so that the tabletops of the worktables can move to the inkjet printing area and the screen printing area, and in addition, the tabletops of the worktables can move back and forth between the inkjet printing area and the screen printing area. The number of the worktables is two. When the tabletop of one worktable moves to the inkjet printing area, the tabletop of the other worktable moves to the screen printing area; and when the tabletop of one worktable moves to the screen printing area, the tabletop of the other worktable moves to the inkjet printing area.

The invention discloses an aluminized and printed composite packaging film for tobaccos and a preparation method of the aluminized and printed composite packaging film. The composite packaging film comprises a printed packaging film and an aluminized packaging film which are compounded by using an adhesive, and the composite packaging film can be obtained by compounding a printed layer of the printed packaging film with an aluminized layer of the aluminized packaging film. The invention creatively puts forwards the combination of a printed surface of the printed packaging film and an aluminized surface of the aluminized packaging film, so that not only is the problem that the heat sealing performance of the fully-printed surface of an existing printed packaging film is reduced solved, butalso the aluminized and printed composite packaging film has extremely high barrier performance; due to the combination of the printed surface of the printed packaging film and the aluminized surfaceof the aluminized packaging film, not only can double surfaces be subjected to heat sealing, but also a printing function is realized, and the aluminized layer is prevented from being scratched; and the aluminized and printed composite packaging film for tobaccos realizes low-temperature heat sealing on the basis of existing functions, effectively reduces the energy consumption and is environment-friendly.

The invention discloses a multifunctional pencil sharpener. The multifunctional pencil sharpener comprises a pencil rotating assembly and a printing assembly. The pencil rotating assembly comprises a pencil sharpener shell and a blade. A pencil rotating groove is formed in the surface of the pencil sharpener shell. The blade is arranged in the pencil rotating groove. The printing assembly comprises a seal shell and an idler wheel type seal mounted in the seal shell. A pattern layer is arranged on the surface of the idler wheel type seal. The seal shell is connected to an opening in the lower end of the pencil sharpener shell through an intermediate connecting body. An inner cavity of the seal shell, an inner cavity of the intermediate connecting body and an inner cavity of the pencil sharpener shell are communicated. A filter screen used for separating wood chips from graphite particles is arranged in the inner cavity of the intermediate connecting body or the inner cavity of the pencil sharpener shell. The multifunctional pencil sharpener has the advantages that when a pencil is sharpened, graphite dust enters the inner cavity of the intermediate shell by penetrating through the filter screen, the wood chips are left in the pencil sharpener shell, the wood chips can be poured out independently by unscrewing the pencil sharpener shell from the intermediate shell, and environment pollution caused by raising of the graphite dust is avoided.
