The invention relates to an injection-molded one-piece keyboard with an I-shaped keycap, a mold and a production method. The keyboard comprises the one-piece I-shaped keycap, a printed circuit film and a keyboard base plate which supports the printed circuit film. Through slotting guidance of a hard sheet, a soft plastic convex flexible switch body is integrally injection-molded at the center inside the hard sheet. The soft plastic convex flexible switch body is directly molded at the center of the hard sheet. When pressing is carried out, the soft plastic convex flexible switch body is directly pressed by the hard sheet, so that the pressing accuracy is high. The technical problems of injection molding and mold stripping of a traditional structure are solved. The entire keyboard has the advantages of small key surface gap and smooth key surface. An adhesive structure is used, so that the keyboard has the advantages of less product parts, thin overall thickness, light weight, simple assembly and low cost. A positioning ring is arranged at the bottom surface of the hard sheet to improve the pressing feel and balance.

The automatic young fruit bagging machine of the present invention can realize automatic pressing and bagging, thereby improving bagging efficiency and reducing labor intensity; the front end of the fork plate device adopts a V-shaped opening design, which effectively avoids the problem of broken fruit handles in the bagging process.

The invention discloses a pneumatic pressing and ironing machine for clothing printing and ironing. The pneumatic pressing and ironing machine comprises a rack, a pressing and ironing table, a pressing and ironing device and a clamping device. The pressing and ironing device comprises an upper pressing and ironing plate, a lower pressing and ironing plate and a pressing and ironing air cylinder. The bottom face of the upper pressing and ironing plate is provided with a limiting protruding block, a clamping groove and an air outlet hole. A guiding device is arranged between the upper pressing and ironing plate and the lower pressing and ironing plate. The clamping device comprises a clamping air cylinder, an upper air clamp and a lower air clamp. The pneumatic pressing and ironing machine is simple in structure and high in practicality; by means of design of the guiding device, pressing precision between the upper pressing and ironing plate and the lower pressing and ironing plate is higher, and the quality of clothing pressing and ironing is improved; meanwhile, as the limiting protruding block and the limiting groove are matched, the situation that the two pressing and ironing plates are dislocated can be prevented, the production efficiency of the pressing and ironing machine is improved by means of the clamping device, the lower air clamp can have effects of fixing and supporting the lower pressing and ironing plate, the parallelism between the lower pressing and ironing plate and the upper pressing and ironing plate is guaranteed, and comprehensive utilization efficiency is improved.

The invention discloses a novel pressing claw device, which includes a pressing plate, a driving part for driving the pressing plate, several pressing jaws located under the pressing plate, and a base for carrying various parts. There are installation parts for installing the pressure claws at intervals between the seats, and installation gaps are formed between adjacent installation parts; installation bosses are arranged at intervals at the rear of the opposite side of the installation parts, which are located at the junction of the installation part and the installation gap, and the adjacent installation bosses A mounting concave platform is formed between them; the tail of the pressing claw is provided with a snap-in element, and the snap-in element snaps in from the installation gap; one or two pressure claws are snapped into the installation gap, and the snap-in end of the snap-in element is placed on the installation protrusion On the platform or on the installation concave platform; the pressure claw is rotatably connected to the installation part; the new pressure claw device provided by the present invention has a more accurate crimping position, a more suitable pressing force, and has high compatibility, adapting to multiple specifications of batteries Chip crimping work, improve product quality.
