Description

Technical Field

[0001] The present invention relates to the field of press forming and shaping processing, and in particular to a fast and accurate press forming system and process. Background Art

[0002] An automatic production line is a form of production organization that uses an automated machine system to realize the product process. It is formed on the basis of the further development of the continuous assembly line. The processing object is automatically transferred from one machine tool to another, and the machine tool automatically processes, loads and unloads, and inspects it; the worker's task is only to adjust, supervise and manage the automatic line, and does not participate in direct operation; all machines and equipment operate at a unified rhythm, and the production process is highly continuous.

[0003] However, there is a lack of fully automated production lines for granular product pressing processing on the market. The existing pressing processing technology for granular product seed materials mainly places the product seed materials in the pressing device and squeezes the product seed materials from the upper and lower directions through the pressing surface with a flat surface, so as to obtain a beautiful product seed material appearance that meets the market preferences and meets the company's product requirements. The current pressing technology solutions all use hydraulic balers to press seeds, or barrels to press seeds, that is, a fixed number of product seed round fruits are placed in a fixed space, and then the space is squeezed through hydraulic equipment, so that the product seeds in the space squeeze each other and deform, so that the product seed materials change from a rugby shape to a flat shape, and then cut from the flat surface, divided into two, to obtain two pressed finished product seed material sheets. The product seed material sheet obtained in this way has a flat opening, and there is a texture similar to a lotus leaf on the cut edge, which is beautiful in appearance and meets the current market aesthetic requirements for the appearance of finished product seed materials. However, traditional seed pressing adopts large-scale centralized mixed pressing. Each seed pressing cavity is filled with 80-500kg of product seeds. The package seed press presses about 500kg of seeds each time, and the pressure holding time is 1-12 hours. The drum seed press presses 80-100kg of seeds each time, and the pressure holding time is 24-72 hours. The quality of the pressed seeds cannot be guaranteed, and a large amount of seeds are wasted. The product seeds are heated by a single microwave or a single steam to 45-65℃, and the heating efficiency is slow. It is easy to overheat and damage the quality of the product seeds.

[0004] After searching, the patent number "CN218605016U" discloses a rapid forming machine, in which a conveyor belt is set between the relative presses, and a relatively set shaping mold is installed on the press, and a heating component and a cooling component are respectively arranged in the shaping mold; an X-axis moving module is arranged on the outside of the shaping mold, and a feeding device is arranged on the X-axis moving module, and a feeding frame is fixedly installed on the X-axis moving module, and a suction cup assembly is arranged in the feeding frame, and a solenoid valve group and a vacuum gas storage tank are respectively installed on the suction cup assembly; the servo motor is connected to the Y-axis moving module by transmission, and one end of the Y-axis moving module is fixedly connected to the suction cup assembly. However, the above scheme is complex in structure, and still requires manual intervention to participate in operations such as feeding and cleaning the mold, which affects the production and processing efficiency.
