This invention discloses a self-service printing device, comprising a housing with an observation window and a temporary storage mechanism and a release mechanism located within the housing. The temporary storage mechanism consists of multiple parallel and inclined support units arranged sequentially along the normal direction of the observation window; the front support unit and its paper obscure the content area of ​​the rear paper, with only the side serial number area exposed. Each support unit has a support plate, a holding member, and a conductive bead. The release mechanism has electrical contacts aligned with the conductive beads. When the contact is activated, it drives the corresponding holding member to switch from holding to releasing, allowing the target paper to slide out along the support plate. This structure achieves physical obscuring of the content area and visibility of the serial number during the temporary storage stage, supporting accurate single-page release; the side serial number is permanently exposed for easy identification and position mapping; the number of contacts is small, the wiring is simple, and the paper is fed by gravity, reducing the risk of missorting and jamming, improving confidentiality, efficiency, and reliability; the structure is modular and easy to maintain.

The application provides a nylon FDY 20D hot melt yarn warping equipment and a process thereof, and the hot melt yarn warping equipment comprises, from right to left, a creel, a yarn collecting plate, a first pneumatic long strip clamp plate, a yarn dividing needle assembly, a second pneumatic long strip clamp plate and a warping head; each front end of a spool of the creel is provided with a KFD yarn tension regulator; the warping head is provided with a main yarn dividing needle and a yarn guide roller; the first pneumatic long strip clamp plate and the second pneumatic long strip clamp plate each comprise a base plate, two cylinders, an upper pressing plate and a rubber pad; the two cylinders are arranged at two ends of the base plate; the two ends of the upper pressing plate are respectively arranged on the two cylinders and are connected with push rods of the two cylinders; and the rubber pad is arranged at a lower end of the upper pressing plate; the distance between the second pneumatic long strip clamp plate and the main yarn dividing needle is 50-80 cm. The application realizes warping of nylon hot melt yarn of 20D specification, has the advantages of simple winding control, long service life, good reliability, reduced labor intensity, greatly improved production efficiency and beam quality.

The utility model discloses a kind of aluminum alloy chemical polishing devices, belong to aluminum alloy processing technical field, including frame, frame one side is equipped with controller, frame bottom end four corners are equipped with stand, frame is equipped with placing frame inside, placing frame is equipped with multiple baffle in straight line array distribution, frame both sides are fixedly installed with support frame, frame upper is equipped with lifting plate, lifting plate section is inverted "U" shape, two sections of lifting plate are respectively slidably placed in the same side support frame, two support frame bottom end inner wall are equipped with cylinder, two cylinder piston shaft end portion are fixedly connected with the opposite side of lifting plate, swing component is equipped between placing frame and lifting plate, lifting plate top is equipped with wind blowing component.The utility model places multiple placing areas by baffle in placing frame, it is convenient to separate and place aluminum alloy plate, it is conducive to reducing the contact point between plate, in turn, it is conducive to improving the contact area of plate and solution, in turn, it is conducive to improving the polishing effect of plate.

The application discloses a piece contact plug-in structure, which comprises a spring piece and a clamping shell, the spring piece is arranged in the clamping shell, the spring piece comprises an upper spring piece and a lower spring piece which are arranged in an up-down mode and form a plug-in slot, the upper spring piece and the lower spring piece each comprise a spring piece base body, the spring piece base body is provided with a first cantilever and a second cantilever, the second cantilever is located in a different height plane from the first cantilever, the gap between the first cantilever and the second cantilever is infinitely reduced to zero, the number of cantilevers is increased, the number of contact points is increased, the conductive performance is improved, the conductive performance is improved, the width of the spring piece base body is fully utilized, the spring piece body resistance is reduced, the current carrying capacity of the spring piece is improved, and the problem that in the prior art piece contact, the number of cantilevers and the spring piece body resistance value are fixed without increasing the width of the spring piece base body, the conductive performance and the current carrying capacity are fixed, and the conductive performance and the current carrying capacity cannot be improved is solved.
