The invention provides an auxiliary unloading device for a circular wound needle. The auxiliary unloading device comprises a lower locating structure, a needle pulling stop block, an opening mechanism, an upper prepressing plate pressing against the upper position on the outer side of a circular cable core and a prepressing driving mechanism for enabling the upper prepressing plate and the lower locating structure to do relative opening and closing motions, wherein when the circular cable core on a circular wound needle mechanism is placed on the lower locating structure and locked by the needle pulling stop block, and the opening mechanism is arranged on the inner side of the circular cable core in an extending manner and located on the inner side or the upper prepressing plate presses against the upper position on the outer side of the circular cable core, the circular wound needle mechanism backwards moves along the axial direction of the circular cable core and is separated from the circular cable core; the separated circular cable is prepressed into an elliptical cable core under the cooperation of the opening mechanism, the lower locating mechanism, the upper prepressing plate and the prepressing driving mechanism, so that the problem of unloading of a circular wound needle after winding and the problems of wrinkling and edge collapse of a membrane on the inner ring of an elliptical rolled needle are solved, and a compact structure is realized. Meanwhile, the invention further discloses cable core winding equipment and a cable core forming method.

The invention relates to the technical field of medical supply transportation, and in particular relates to a logistics vehicle for transporting medical supplies. The logistics vehicle for transporting the medical supplies comprises a bottom plate, a first electric push rod, a damping pad, a sliding block and a bearing plate, the first electric push rod is fixedly arranged on the left side of the upper surface of the bottom plate, a connecting shaft is fixedly connected with the surface of the first electric push rod, a movable groove for moving the sliding block is formed in the bottom plate, a damping pad is fixedly arranged in the movable groove in the bottom plate, a sliding block is movably installed in the bottom plate, a bearing plate is rotationally installed above the connecting shaft, and rolling wheels are rotationally installed above the bearing plate. The logistics vehicle for transporting the medical supplies has the beneficial effects that the logistics vehicle for transporting the medical supplies is improved on the basis of an existing logistics vehicle, the medical supplies of different sizes are stably transported through side connecting plates on the device, meanwhile, automatic loading and unloading can be conducted, and the convenience of overall use is improved.

The invention provides a device and a method for testing diffusion coefficients of gases, in particular provides a device and a method for testing diffusion coefficients of volatile liquid-air (or other gases), aims to overcome defects that when liquids are injected from upper parts of diffusion tubes during conventional operation, balance is difficult to keep all the time and the liquids stick to walls of the diffusion tubes easily and solves problems that the diffusion coefficient testing accuracy is affected and the like due to the fact that larger convection disturbance can be caused to gas space in the diffusion tubes when the liquids are injected from the upper parts of the diffusion tubes. With the adoption of the device, the liquids can be injected into the diffusion tubes from bottoms automatically, stably and slowly, so that the obvious convection disturbance effect cannot be caused to the gas space above the liquids , several liquids can be tested simultaneously, and the testing efficiency is improved. Besides, in consideration of safety, the glass diffusion tubes are vertically fixed in a temperature-control digital-display glass thermostatic water bath, and the safety of a testing system is improved finally while the testing accuracy is improved.

The invention provides a self-unloading carriage for closed type truck, which can be formed by refitting the existing freight car and the box car. The self-unloading carriage is used for transporting bulk commodities on the railway and can also serve as a box car. The invention overcomes the shortcomings of large road loss, much contamination and high gravity center of the transportation with gondola car and is a self unloading carriage for closed type truck with the function of self unloading, no road loss of the freight and lower gravity center.

The invention discloses a thermal power spinning machine unloading mechanism, which includes a pulling mechanism, a clamping mechanism, and a discharging ring. Installed in the U-shaped groove of the rotary wheel, the pulling force is provided by the movement of the rotary wheel guide rail; the clamping mechanism is similar to a four-bar mechanism, which is mainly composed of a fixed plate, a connecting rod, a ring frame, and a chuck. The nut connected with the frame moves the moving rod left and right, so that the chuck of the clamping mechanism can clamp and loosen the workpiece; the structure of the unloading ring is designed as a combination, and the unloading ring and the cylindrical The parts are connected by multiple stop cones; the advantages of the present invention: the unloading mechanism designed by the present invention is simple in structure and light in weight, which can well solve the unloading problem of the hot and powerful spinning machine; the structural form of the combined unloading ring The disadvantages of the integral unloading ring such as easy wear, complicated design and manufacture, high manufacturing cost and low material utilization rate are solved.
