A process for making integral elastic supports, such as chair seats, seat backs, arm rests, bicycle saddles and vehicle seats and the like, including the following steps: a) making a shell (2) with a predetermined shape and structure; b) setting up a mold (5) with at least one inner cavity (6) and capable of being moved from an open condition to a closed condition; c) introducing at least one foamable resin and the shell (2) into the inner cavity (6) of the mold (5); d) foaming the resin to form a filler layer (3) to be joined to the shell (2) into a single assembly (7); e) removing the assembly (7) from the mold (5). In greater detail, the shell (2) is manufactured in a first step a1) for making a main body (8) having a peripheral edge (9) and a second step a2) for making a sealing member (10) in the proximity of the peripheral edge (9), to essentially close any gap between the shell (2) and the inner cavity (6) in the proximity of the peripheral edge (9) and prevent the formation of burrs as the foamable resin is foamed.

The invention discloses a mail automatic sorting device. The mail automatic sorting device comprises a bracket; the bracket is provided with a conveying mechanism for conveying mails; and the conveying mechanism comprises multiple conveying rollers. The mail automatic sorting device further comprises a sorting mechanism for sorting mails to be sorted; the sorting mechanism comprises a transmissionmechanism, a lifting mechanism, and multiple sorting wheels mounted on the transmission mechanism; the multiple sorting wheels are uniformly arranged among the multiple transmission rollers; includedangles between each sorting wheel and the axes of transmission rollers are the same; the lifting mechanism drives the conveying mechanism to drive the sorting wheels to perform a lifting motion amongthe transmission rollers; and the conveying mechanism drives the sorting wheels to rotate to sort out the mails to be sorted. The mail automatic sorting device reduces the manual needs, reduces the sorting cost, and achieves high sorting efficiency.

The invention belongs to the technical field of optical fiber manufacturing, and discloses a method for manufacturing a polarization-maintaining optical fiber, comprising the following steps: on the wall of the first layer of casing, cutting a notch symmetrically with respect to the center line of the inner cavity of the first layer of casing; Stress rods are filled in the incision, and an optical fiber preform core rod is embedded in the first layer of casing; a second layer of casing is nested outside the first layer of casing to form a polarization-maintaining optical fiber preform; The polarized optical fiber preform is drawn into a polarization-maintaining optical fiber; wherein, the structure of the gap is filled by a stress rod. During the high-temperature drawing process, the circular stress rod will greatly fill the gap in the cut after softening, forming a polarization-maintaining optical fiber. required stress zone. The invention proposes a polarization-maintaining optical fiber manufacturing method with double sleeves and stress rods, which has a simple structure, greatly simplifies the processing technology and reduces the requirements for labor and equipment; it can greatly improve the impact of impurities on product quality; at the same time, it avoids Various high-precision operation requirements in the prior art.

The invention relates to the field of book management and discloses a school library book automatic identifying and sorting device. The school library book automatic identifying and sorting device comprises a conveying table. A recognition table is fixedly connected to the left side of the conveying table. Stacking tables and sorting tables are arranged on the upper and lower sides of the conveying table correspondingly. The upper portion of the recognition table is fixedly connected with supporting rods. The tops of the supporting rods are fixedly connected with an inclined plate. The right side of the inclined plate is connected with a rotary seat. The rotary seat is fixedly connected with a baffle. The lower portion of the baffle is hinged to a first cylinder piston rod. The inclined plate is fixedly connected with a probe stand column. The probe stand column is fixedly connected with a recognition probe. The school library book automatic identifying and sorting device can be used for classifying returned library books, can automatically judge the type of the books under the combined action of sensors and cylinders and place the different types of books onto the different stacking tables, greatly reduces manual operation and is higher in efficiency, more accurate in sorting and suitable for application and popularization in various large libraries.

The invention discloses an automatic unpacking system of an electric energy meter. The automatic unpacking system comprises a control system, and further comprises an automatic unpacking unit, an electric energy meter sorting unit, a carton recycling and processing unit, an automatic high-voltage insulation testing unit, an appearance and foreign matter detecting unit, an automatic packing unit and an unstacking / stacking storage inlet unit, all of which are connected with the control system and arranged on a conveyor line. According to the system, the full-automatic electric energy meter is adopted, unpacking, sorting, high-voltage insulation testing, appearance and foreign matter detecting, packing, stacking and unstacking are carried out automatically, intelligent control from unpacking to stacking storage inlet of the electric energy meter is achieved, the labor cost is reduced, the labor intensity in the existing electric energy meter unpacking process is reduced, and the problems that the unpacking working efficiency is low and the electric energy meter is damaged in the unpacking process are solved. The automatic high-voltage insulation testing device and the automatic appearance and foreign matter detecting device are adopted in the whole process, the inspection result is unified, nonuniformity of result targets caused by subjective factors of people in the manual checking process is avoided, and the detecting quality of the electric energy meter is improved.
