The invention relates to a cork pressing device for a burgundy bottle cork, in particular to a multi-bottle type manual cork pressing device. At present, all cork pressing devices used in wine production are large mechanical devices, which generally have inconvenient movement, a single function, and are not suitable for producing small-size unusually shaped bottles with more varieties and bottle types. The device consists of the following parts including a support body, a bottle holding and positioning disk, a bottle opening positioning device, a replaceable cork accommodating device, a wooden cork accommodating device shell, a pressure bar arm handle, a cork accommodating push rod and a cork beating column, wherein the bottle opening positioning device and the replaceable cork accommodating device can be replaced according to outer shapes and inside diameters of the bottle types. The multi-bottle type manual cork pressing device has the advantages of simple structure, readily available material, easy manufacturing, low cost, simple and convenient operation and usage and free movement, is suitable for the multi-bottle type or unusual shaped bottle manual cork pressing device, and has strong practicability.

The invention discloses an automatic skin feeding machine, and relates to the field of precise mechanical devices. The machine comprises an upper mold device, a lower mold device, a transmission device and a heating device which are arranged in a rack; an automobile door base plate is clamped on the upper mold device, the heating device moves to the position below the automobile door base plate along a guide rail and carries out baking and heating on the automobile door base plate, the upper mold device is pushed by the transmission device to descend to be assembled with the lower mold device, and skin is placed on a bottom mold in the lower mold device; ventilation holes are formed in the bottom old, a vacuum adsorption mechanism is arranged on the lower side of the bottom mold, and the skin is adsorbed by the vacuum adsorption mechanism to be attached to the surface of the bottom mold; an embedded cutter set ascending from the lower side of the skin is arranged on the bottom mold, and the automobile door base plate is coated with the skin through the embedded cutter set along the edge of the skin. According to the automatic skin feeding machine, the skin is fixed in a vacuumizing fixing manner, the traditional clamping manner is improved, and processing is better and more convenient. Meanwhile, the heating manner of the base plate is further improved, and the melting effect of hot melt adhesive is more ideal.

The invention relates to the technical field of multi-mechanical devices, in particular to a safe discharge nuclear capacity structure. The discharge nuclear capacity structure comprises a main control room, a wiring board, a storage battery pack and a discharge instrument; the main control room is electrically connected with the wiring board; the wiring board is both electrically connected with the storage battery pack and the discharge instrument; a controllable switch and a plurality of first circuit breakers are arranged between the main control room and the wiring board; the wiring boardand the storage battery pack are provided with second circuit breakers; and the storage battery pack is electrically connected with the discharge instrument through a detachable power-on structure. According to the safe discharge nuclear capacity structure, the wiring board with an operation link is not electrified when the discharge instrument is dismounted during nuclear capacity discharge, so that the possibility that the positive electrodes and the negative electrodes of storage batteries are connected to form a short circuit is avoided, safety accidents are reduced, and the personal safety of maintenance personnel and the equipment safety are ensured.

The invention discloses a gear type self-adapting transmission. The gear type self-adapting transmission comprises a first planetary gear mechanism, two or more groups of second planetary gear mechanisms, a third planetary gear mechanism, a fourth planetary gear mechanism, two groups of planetary gear regulating mechanisms, a central shaft, a controlled end and a control end, wherein the second planetary gear mechanisms are parallel to the central axis, the first planetary gear mechanism, third planetary gear mechanism and fourth planetary gear mechanism are arranged along the same axial line, and the central axes are the same. The gear type self-adapting transmission is capable of automatically regulating the speed and torque to enable the transmission to always locate at the best matching state according to the engine power and vehicle driving resistance change without cutting off driving force, and the stepless speed change can be realized in the presence/absence of program control and external effect; the gear type self-adapting transmission is suitable for different vehicles, the driving efficiency is higher, the fuel economy is better, and the speed increase is faster; the gear type self-adapting transmission can also be used for the other mechanical devices which need speed change.

The invention relates to the technical field of mechanical equipment, in particular to a double-wire guardrail mesh electric resistance welding machine. The welding machine can effectively simplify the production mode, improve the automation degree, save labor and improve the working efficiency by carrying out automatic wire feeding and welding treatment on a double-wire guardrail mesh, and meanwhile, the distribution uniformity of welding spots on the mesh is improved, the attractiveness and the strength of the mesh are improved, the mesh production quality is effectively improved, and the practicability and the reliability are improved. The electric resistance welding machine comprises a first main welding machine, a second main welding machine and an automatic net falling device, the right end of the first main welding machine is connected with the left end of the second main welding machine, and welding mechanisms are arranged on the right side of the first main welding machine andthe right side of the second main welding machine.

The invention provides a wall-attached type foldable vehicle-mounted sunshade and belongs to mechanical devices. The wall-attached type foldable vehicle-mounted sunshade mainly solves the problems existing in structure and function design. The wall-attached type foldable vehicle-mounted sunshade is composed of a base, a left suction nail, a sun louver and a right suction nail and is characterized in that the foldable sun louver is fixed to the base, the left suction nail and the right suction nail are installed on the two sides of the inner surface of the sun louver, when the sunshade is used, the base only needs to be placed at the top of a small vehicle, the left suction nail is simply pressed and attached to a front windshield of the small vehicle, and the right suction is simply pressed and attached to a rear windshield of the small vehicle. The wall-attached type foldable vehicle-mounted sunshade has the advantages of being foldable, convenient to operate, simple in structure and long in service life.
