DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0013] The features and advantages of the present invention will be described in further details with reference to the drawings.

[0014] As shown, a molding machine with adjustable wheel rollers which comprises a frame 1, wheel rollers 2 and 3 mounted on a frame, a transmission mechanism, a gear of the transmission mechanism being connected to a gear of the upper roller and two gears occlusive together to drive the upper roller running and upper roller driving the lower wheel roller for relative operation, wherein the two ends of the said wheel roller are fixedly connected with the frame through a bearing; the said lower wheel roller 3 as an adjustable wheel roller is constituted by an outer roller 21, an adjustable wheel core 22 and a bearing 23; the said outer roller is arranged outside the bearing and the adjustable wheel core passes through the bearing center; both ends of the adjustable wheel core are connected to the frame with an adjustment knob connected with the adjustable wheel core arranged on the outside of the frame. Adopting the way of rotation of a single roll and driving the rotation of auxiliary wheel, the method is simple and practical by simply adjusting the up-and-down motion of the lower roller to meet the needs of the distance change between the two rollers.

[0015] In order to achieve the function of heating, the heating device inside the roller is connected with the external power source; a rotating carbon brush is provided on the frame and the bearing, and the inner side of the rotary brush is connected with the heating device inside the roller while the outer side of the rotary brush is connected with the external power source by means of the connecting wires. The function of hot stamping and other multifunction can be achieved by heating the molds with the technical solution above mentioned.
