The present invention relates to N,N-dimethyl imidodicarbonimidic diamide acetate, a method of preparing the same and a pharmaceutical composition comprising the same, and more particularly, to N,N-dimethyl imidodicarbonimidic diamide acetate which is a crystalline acid addition salt prepared by reacting N,N-dimethyl imidodicarbonimidic diamide with acetic acid, and which is very effective as a therapeutic agent for treating metabolic syndromes that glycosuria and diabetes mellitus, obesity, hyperlipidemia, fatty liver, coronary heart disease, osteoporosis, polycystic ovarian syndrome, a cancer depleted of gene P53, etc. are complexly occurred; treating diabetes mellitus and preventing its complication; and treating a cancer and preventing myalgia, muscle cell cytotoxicity and rhabdomyolysis, etc. since the acid addition salt is excellent in physicochemical properties such as solubility, stability, non-hygroscopicity, anti-adhering property, etc., and low toxicity, a method of preparing the same and a pharmaceutical composition comprising the same.

The invention discloses a drawing frame which is composed of a feeding mechanism, a combining mechanism, a drafting mechanism, an output mechanism and a transmission control mechanism. The drawing frame is characterized in that a rear roller of the drafting mechanism is composed of a left rear roller, a right rear roller and a rear roller shaft. The left rear roller is fixedly connected with the rear roller shaft, and the right rear roller is sleeved on the rear roller shaft moveably. A rubber roller matched with the rear roller comprises a left rear roller upper rubber roller, a right rear roller upper rubber roller and a central shaft. The left rubber roller and the right rubber roller are fixed on the central shaft, and the central shaft is fixed and does not rotate. The left rear roller upper rubber roller rotates independently through the matched left rear roller, and the right rear roller upper rubber roller rotates independently through the matched right rear roller. Output speeds do not interfere with each other. Two independent holding jaws are formed. The transmission control mechanism is matched with the structure of the rear roller, output speeds of the left rear roller and the right rear roller are controlled by a left stepping motor and a right stepping motor, and the total amount of strips output by the rear roller is not changed.
