The invention relates to the technical field of design of additively manufacturing machine tool parts, in particular to a device for easily peeling forming parts obtained by additive manufacturing on a printing table. The device comprises a printing base, a preheating substrate, two printing substrate groups and two jacking mechanisms, wherein each printing substrate group comprises a plurality of printing substrate units; the plurality of printing substrate units are arranged in parallel at intervals; the preheating substrate is arranged on the printing base; the two printing substrate groups are separately arranged above the preheating substrate; one printing substrate unit of the other printing substrate group is arranged between every two adjacent printing substrate units of one printing substrate group; each printing substrate group is in driving connection with one corresponding jacking mechanism; and the jacking mechanisms are used for driving the corresponding printing substrate groups to vertically move. According to the device for easily peeling the forming parts obtained by additive manufacturing on the printing table, provided by the invention, the two substrate groups vertically move in a spaced manner, so that objects formed on the printing substrates can be effectively sheared, and the forming parts bonded on the printing substrates are peeled with less labor.

The invention belongs to the technical field of computer hardware designs and provides a liquid crystal display screen capable of automatically controlling the temperature. The liquid crystal display screen comprises a temperature detection unit, an operation state detection unit, a judgment unit and a control unit, wherein the control unit is used for receiving a temperature judgment result sent by the judgment unit and then controlling a heating unit to heat; and after the heating unit executes heating actions, the heating unit is controlled to stop heating according to a judgment result that a current temperature of the crystal display screen is higher than that a pre-set temperature threshold judged by the judgment unit. According to the liquid crystal display screen capable of automatically controlling the temperature, the heating unit is used for heating when the temperature of the liquid crystal display screen is too low, so that a working temperature of the liquid crystal display screen under a low temperature environment is improved; the problem that performances of the liquid crystal display screen are reduced under the low temperature environment is avoided; the performances of the liquid crystal display screen is guaranteed and the service life is prolonged; and an application range of the liquid crystal display screen is expanded.
