The invention discloses a mechanical device for automatically opening flax round packages from flax comprising a frame, a guide roller, an electrical motor, and is characterized in that the mechanical device is further provided with a round package uncoil-stand, a string-pulling device and a conveyer device, wherein the electrical motor is connected with the conveyer device via a transmission belt, the conveyer device respectively drives the round package uncoil-stand and the string-pulling device, the round package uncoil-stand is a triangle transmission device consisting of an uncoiling guide roller and an uncoiling belt, the string-pulling device comprises a belt roller and an iron roller, and the conveyer device is a plate-type conveyer device consisting of a conveyer guide roller anda conveyer belt. The invention has high labor efficiency and low labor intensity.

The invention relates to a ramie high-temperature gas explosion degumming process. The process applies degumming process, and the degumming process applies alkali solution. The degumming process is characterized in that degumming process includes unpacking and unbinding process, feeding process, first high-temperature gas explosion process, first extruding process, second high-temperature gas explosion process, second extruding process, third high-temperature gas explosion process, and third extruding process, wherein a high-temperature high-pressure flushing method is applied; ramie is flushed under the alkali solution in the first high-temperature gas explosion process, the second high-temperature gas explosion process and the third high-temperature gas explosion process; the alkali solution temperature is kept at 80-90 DEG C or 95-100 DEG C; the alkali solution pressure is kept at 0.8-1.0 MPa or 1.0-1.2 MPa; the heat preservation and pressure maintaining times of the alkali solution are 3-5 minutes or 5-10 minutes. The process cancels the binding, packing, softening, and loosening processes, shortens the technical flow, promotes quality of the degummed ramie, improves production efficiency, decreases cost and reduces environmental pollution.

The invention provides a packaging bag comprises a first sheet body and a second sheet body. The first sheet body and the second sheet body comprise two first fold lines and two second fold lines, respectively; when the first sheet body and the second sheet body are unfolded, the second fold lines are located between the first fold lines; viewed from the outer surfaces of the first sheet body and the second sheet body, the first fold lines are valley lines and the second fold lines are mountain lines. By folding the first sheet body and the second sheet body according to the first fold lines and the second fold lines, respectively, when the packaging bag is torn, the first sheet body and the second sheet body can be unfolded to from a relatively big opening, so that the packaging bag is easy to take, the user can know the residual amount in the packaging bag, and the problem of a messed environment is solved as scattered biscuit chips in a taking process can be held.

The invention discloses a foldable stretcher special for emergency internal medicine, and belongs to the field of medical apparatuses and instruments. The foldable stretcher comprises a shrinking device, a rotating fixing device and a folding frame device, wherein the shrinking device comprises a first outer sleeve and a second outer sleeve, a first shaft rod and a second shaft rod are rotationally arranged in an inner cavity of the first outer sleeve and an inner cavity of the second outer sleeve respectively, the outer wall of the first shaft rod and the outer wall of the second shaft rod are each fixedly provided with a clockwork spring, a clockwork and a rolling cloth, a pulling rod is fixedly arranged at the other end of each rolling cloth, the inner wall of the first outer sleeve andthe inner wall of the second outer sleeve are each rotationally provided with a thorn block, a clamping jaw sleeves the side wall of each thorn block, and the outer walls of all the clamping jaws areeach fixedly provided with a spring cylinder and a shifting rod. According to the foldable stretcher special for emergency internal medicine, the rolling cloth can be shrunk into the inner cavities of the outer sleeves, it is avoided that the rolling cloth is exposed in air, breakage and mess of supporting cloth are reduced, the service life of the rolling cloth is prolonged, the occupied space is reduced, the crowdedness degree of a hospital is reduced, it is achieved that the stretcher has the slope function, the foldable stretcher is suitable for emergency treatment of acute gastric disease patients, and the practicability is improved.
