A rotary egg tray machine is a continuous (drum) former, also known as a rotary polygon former. A common rotary egg tray machine consists of a transmission and speed regulating device, a drum, a stripper, a cleaner and a controller.
The drum of the rotary egg tray machine is to install the metal mesh to form the cavity seat of the sealed cavity. 18~48 molds. The transfer mold is assembled on a pair of four-bar linkage mechanisms, and the drum is driven by a motor to drive a sheave mechanism to rotate to realize intermittent rotation, so as to ensure that when the mold is clamped with the transfer mold, there is a pause time for the wet paper mold blank to be smoothly transferred to the transfer mold. on the drying chain. During molding, the mold in station I is immersed in pulp, and its drum cavity is connected to the vacuum suction system in turn through the distribution device distributed on the end face of the drum, and the molding mold is sucked to produce a wet paper mold blank. When the forming mold is transferred from station I to station II and III, the vacuum suction state is still maintained, and the formed wet paper mold blank is dehydrated in large quantities. When transferred to stations IV, V, and VI, the wet paper mold blanks enter the heat insulation cover with the mold temperature of 240~260 °C and continue to be dehydrated and dried. When transferred to station VII, the forming die and the transfer die are clamped and demolded, and the wet paper die is rotated 90° by the transfer die and released to the drying conveyor belt. At the same time, the demolded forming die rotates with the drum. At station VII, the water purifying nozzle sprays water to clean the forming mold, and finally the cleaned forming mold is transferred to station I to start a new working cycle. The rotary egg tray machine has a high degree of automation, high production efficiency, and a production capacity of 5 to 6 times per minute. Because its forming molds are arranged on a rotatable drum, the pressure it bears is low, and its wet paper mold blank is denser. It is not suitable for the production of tableware, and it is more suitable for large-scale continuous automatic production of small wall thickness and depth. Shallow plate thin-walled cutlery. At present, this kind of equipment is commonly used to produce trays, egg trays, bottle rack trays, fruit boxes, electrical appliances lining packaging and other non-soup products.
