Automatic spring-roll shaping apparatus

An automatic spring-roll shaping apparatus adapted to convert a spring-roll semiproduct into a spring-roll product, the spring-roll semiproduct including a body stuffed with fillings, a skin extension extending from the body, and a batter applied on a trailing end of the skin extension, said automatic spring-roll shaping apparatus comprising:

• a machine bed having an upstream end and a downstream end;
• a conveying belt mounted to said machine bed and adapted to move the spring-roll semiproduct from said upstream end of said machine bed to said downstream end of said machine bed, said conveying belt being adapted to be in frictional contact with the spring-roll semiproduct;
• and
• a rolling device including a circular rotating tube that is disposed on and transverse to said conveying belt, that is adapted to be thicker than the spring-roll semiproduct, and that is rotatable between a shaping position, where said circular rotating tube cooperated with said conveying belt to rotate the spring-roll semiproduct in a direction, and a release position, where the spring-roll semiproduct is released from said circular rotating tube so as to be moved by said conveying belt to pass past said circular rotating tube, and pressurization unit disposed immediately upstream of said circular rotating tube and controllable to press the spring-roll semiproduct against said conveying belt and said circular rotating tube so as to allow the spring-roll semiproduct to rotate in situ when said circular rotating tube is disposed at said shaping position, thereby attaching the skin extension onto the body to form the spring-roll product;
• wherein the automatic spring-roll shaping apparatus further comprises a product output device adjacent to said downstream end of said machine bed and disposed downstream end of said rolling device, said product output device including a second supporting unit disposed on said machine bed, and a pressing rod assembly, said pressing rod assembly includes two soft belts disposed between two sides of said conveying belts, and a plurality of equidistant parallel circular bars connected between and transverse to said soft belts, each of said soft belts having an upstream end fastened to said second supporting unit such that, when the spring-roll product output from said rolling device is moved under said pressing rod assembly, said spring-roll product is in frictional contact with four of said circular bars in such a manner that two of said four of said circular bars flank an upper end of the spring-roll product, and the remaining two of said four of said circular bars flank a lower end of the spring-roll product, so that the spring-roll product is parallel to said circular bars when output from said product output unit.
