阅读说明：本技术 改进的食物面团拉伸机 (Improved food dough stretching machine ) 是由 E·达拉丰塔纳 L·斯米德尔 于 2019-07-26 设计创作，主要内容包括：一种面团拉伸机(1),特别适用于拉伸比萨饼面团,其包括框架(11),与框架(11)相关联的是：待拉伸面团块的支承平面(14)；面团拉伸单元(2),布置在顶部并根据框架(11)的限定竖直轴线(Y)与支承平面(14)同轴；运动器件(15),用于使支承平面(14)朝向/远离面团拉伸单元(2)移动。面团拉伸单元(2)包括造形体(21),造形体(21)构造成与面团块接触；板(22),其中识别有多个径向凹槽(22a),每个径向凹槽可滑动地安置有用于面团块的造形元件(3)；运动学器件(4),其适用于移动造形元件(3)沿着径向凹槽(22a)朝向竖直轴线(Y)或远离轴线本身。运动学器件(4)包括：螺纹轴(41),螺纹轴(41)一端(41a)可操作地连接至机动器件(5),而相对端(41b)可旋转地与板(22)关联；中央芯部(42),设有固定在螺纹轴(41)上的螺母(42a)；多个杆(43),每个杆的一端(43a)铰接到造形元件(3)之一,相对端(43b)铰接到中央芯部(42)。运动学器件(4)适于当机动器件(5)使螺纹轴(41)旋转时实现多个杆(43)的圆规运动以及造形元件(3)随之朝向或远离竖直轴线(Y)的移位,引起中央芯部(42)取决于螺纹轴(41)的旋转方向的向下或向上移位。(Dough stretching machine (1), particularly for stretching pizza dough, comprising a frame (11), associated with which frame (11) are: a support plane (14) of the dough piece to be stretched; a dough stretching unit (2) arranged at the top and coaxial with the support plane (14) according to a defined vertical axis (Y) of the frame (11); movement means (15) for moving the support plane (14) towards/away from the dough stretching unit (2). The dough stretching unit (2) comprises a shaping body (21), the shaping body (21) is configured to contact the dough piece; a plate (22) in which a plurality of radial grooves (22a) are identified, each of which slidably houses a shaping element (3) for the dough piece; kinematic means (4) suitable for moving the shaped element (3) along the radial grooves (22a) towards the vertical axis (Y) or away from the axis itself. The kinematic device (4) comprises: a threaded shaft (41), one end (41a) of the threaded shaft (41) being operatively connected to the motorised means (5) and the opposite end (41b) being rotatably associated with the plate (22); a central core (42) provided with a nut (42a) fixed to the threaded shaft (41); a plurality of rods (43), each rod being hinged at one end (43a) to one of the shaping elements (3) and at the opposite end (43b) to the central core (42). The kinematic means (4) are adapted to effect, when the motorized means (5) rotate the threaded shaft (41), a compass movement of the plurality of rods (43) and a consequent displacement of the shaping element (3) towards or away from the vertical axis (Y), causing a downward or upward displacement of the central core (42) depending on the direction of rotation of the threaded shaft (41).)
