The invention discloses a novel cooling structure for a tangent type rotator of an internal mixer, which relates to the tangent type rotator of the internal mixer. The novel cooling structure for the tangent type rotator of the internal mixer disclosed by the invention comprises a central chamber (2), long prismatic chambers (4), (5), (6) and (7), wherein the long prismatic chambers (6) and (7), the central chamber (2), and the long prismatic chambers (5) and (6) are communicated in turn in a F-F axial section through a slotted hole (3); rotator long prismatic chambers (4) and (7) are communicated and the long prismatic chambers (5) and (6) are communicated in an A-A axial section through the slotted hole; and the long prismatic chambers (4), (5), (6) and (7) and the central chamber (2) are communicated in the A-A axial section. Aiming at the conventional tangent type rotator cooling structure, the novel cooling structure for the tangent type rotator of the internal mixer is additionally provided with stiffening ribs and forced water circulation channels are formed, so the area of the cooling water channels are enlarged, the cooling efficiency and the cooling effect are improved, the strength and the rigidity of the rotator are also improved, and the section coefficient of bending resistance is increased.

The invention discloses automatic feeding and discharging equipment of a mobile phone camera module. The automatic feeding and discharging equipment comprises a cabinet body, mechanical arms, couplings, flanges, parallel fixture components, a tray pulling component and a machine light source component; the mechanical arms are installed on the cabinet body, and connected to the flanges through thecouplings, and the parallel fixture components are installed on the flanges; and the tray pulling component is installed on the cabinet body, and the machine light source component is installed besidethe tray pulling components. The feeding and discharging are finished through the tray pulling mechanism, and visual positioning and scanning of QR codes of products are achieved through the machinelight source component; continuous operations, such as material fetching and placement, are finished through the mechanical arms automatically; and the labor cost is reduced greatly, and the automaticfeeding and discharging equipment is professional and efficient. The mechanical arms are used through cooperative application of the couplings and the flanges, and the parallel fixture component at each station is installed on the flange, so that the wiring is reduced; and wires on the flanges penetrate the centers of the couplings so that wear is reduced. With the rotation of the flanges, the stations can be freely switched without error. The automatic focusing of the mobile phone camera module and the random feeding and discharging by the mechanical arms of a finished product machine can beachieved.

The invention relates to a sealing box which comprises a box body, an upper cover and a cover screw, wherein a concave sealing groove is arranged at the upper cover and matched with a sealing ring, a cover screw hole structure is arranged outside the concave sealing groove, the cover screw penetrates the cover screw hole, a strip-shaped peg-shaped dummy club is arranged at the top of the box body,the strip-shaped peg-shaped dummy club is matched with the concave sealing groove, a base and a base mounting hole are arranged at the bottom of the box body, a socket is installed on the base, a strengthening rib is installed on the base, and the thread structure of the cover screw is a feather tongue structure. The sealing box is suitable for various industrial control fields, and especially suitable for the protective sealing box for installing an automatic controller, an electrical switch and a control system in a sealing manner.

The invention relates to the technical field of aircraft manufacturing, in particular to a guard plate and landing gear linkage retracting device. The guard plate and landing gear linkage retracting device comprises a guard plate, a mounting seat, a coordination valve, a support arm and a pressure rod, wherein the coordination valve is fixed to the mounting seat; the pressure rod is arranged on the guard plate and is fixedly connected with the guard plate; one end of the support arm is in contact with the pressure rod, and the other end is movably connected with the mounting seat; the support arm and the coordination valve are positioned in the same mounting plane. The linkage retracting device disclosed by the invention is compact in structure, low in cost, and simple to use and maintain, the retracting reliability for the landing gear can be greatly improved, besides, the requirement for the mounting space of an aircraft is also low, and the retracting device is easy to popularize and use in a hydraulic system of the aircraft.
