Abstract:
A printing machine for printing an integral design on the leaves of a blind comprising:A material distributing device having an inverted-U shaped frame provided with a plurality of vertical separating rods spaced apart equidistantly, a rail space formed between every two said separating rods for receiving said leaves, each said rail space having a sucking disk on top for sucking said leaves and carrying them forward, said frame also having roller units provided on one side for driving said leaves to move forward; A material delivering device consisting of a material propping device and a wheel pressing device, said material propping device composed of a plurality of plates preset in its quantity and connected by a chain, said plates positioned in parallel to said rollers of said material distributing device and having many projections fixed space apart equidistantly on top, a preset space formed between every two of said projections, and said space corresponding to said rail space of said material distributing device, further a propping rod provided in said space of every two said projections of one of said plates, said wheel pressing device having its separating members abutting said material propping device and each said separating member facing said space of said projections, thus abutting two of said leaves moving through said separating members in a vertical condition and then pushed in the pressing wheels of said wheel pressing device, letting the top surface of each said leaf slightly curved up by the pressing of said pressing wheel; A printing device abutting said material delivering device and composed of several printing units preset in its quantity, each said printing unit containing a support wheel and a PU plastic wheel, each said PU plastic wheel having a printing plate wheel provided at a preset position on top of each PU plastic wheel and said printing plate wheel also having an ink wheel thereon so that the color and design attached on said PU plastic wheel can be printed directly on said leaves; A plurality of heat-drying devices preset in its quantity respectively provided behind each said printing unit, said leaf printed with design pushed out of said printing units and carried to said heat-drying devices by a second material propping device, thus the design and color printed on said leaf heat-dried in shape therein; A material tidying device provided with a roller unit to carry said leaf heat-dried to a collecting device, said collecting device having a plurality of separating plates arranged spaced apart equidistantly and connected by a chain, said collecting device having a plurality of collecting spaces formed between every two of said separating plates for collecting said leaves, then a micro-driving device composed of a pressure cylinder and a ratchet and matching with said leaves printed, said ratchet driven to move a tooth distance, said collecting device operated to move a space forward, thus each said collecting space orderly facing separately said leaves one by one, said collecting spaces moving a complete round, each said collecting space collecting a complete unit of said leaves, then each unit of said leaves pushed to said tidying device by said propping and pushing device and tied up stably therein.
