The paper discharge mechanism uses the friction of a paper roller to pull the label out of the bottom of the label magazine. The paper feed roller then delivers the label to the front of the unloading mechanism, where it is then removed by the positioning slider of the clamping mechanism. As it passes through the unloading mechanism, the oil pastel is also removed. As it passes through the pressing mechanism, the pressing roller presses the oil pastel and label into the clamping mechanism.
The clamping mechanism clamps the oil pastel and label in place. As it passes through the gluing mechanism, the film applies glue to both sides of the label. As it passes through the paper reel, the paper reel spring adheres one side of the label to the oil pastel, and a brush adheres the other side. The label is then flattened by the correction wheel, and another brush applies a second coat of paint to secure the label.
The holding mechanism holds the adhered oil pastel in the clamping mechanism to prevent it from being thrown out during operation. When the finished product collection mechanism reaches the top, the holding mechanism ends, the clamping mechanism opens, and the finished product falls under the influence of gravity onto the collection mechanism's conveyor belt and is delivered to the designated location, completing the labeling process.
An independent motor powers the conveyor belt.
The finished product collection mechanism is an independent mechanism whose function is to transport the finished product from the machine via conveyor belt 31 into the finished product box for easy transfer to the next process.
The electrical system is relatively simple, a typical start-stop relay control circuit, and will not be described in detail here.
The raw materials are heated to the appropriate temperature to form a liquid, then placed in a forming mold, cooled, and extruded to form the finished product.
After grinding and formulating, the raw materials are placed in a heating barrel for heating. During the heating process, the raw materials must be stirred while heating to achieve a uniform temperature. The stirring device prevents the raw materials from settling and effectively ensures temperature uniformity.
The forming mold consists of an 830mm circular basin with 432 mold tubes. The mold tubes are carefully crafted from brass rods and made of electroformed copper, achieving a very high internal finish. The mold basin is mounted on a plate controlled by a ratchet and pawl, performing a repetitive circular motion. Once the raw liquid is pressed into the mold cavity by a valve pump, it begins to solidify under the action of cooling water, forming an oil pastel. The circular motion of the mold basin drives the formed oil pastel into the next stage.
As the valve pump injects the raw liquid into the mold, There's solidified excess material left at both ends of the mold. If this isn't removed, the oil pastel cannot be demolded, and the ends will be uneven. Two blades, tightly attached to the upper and lower molds, not only remove the excess material but also act as a force penetrating force between the pawl and the ratchet.
After heating, injection molding, cooling, forming, and cutting, the oil pastel needs to be ejected from the mold. To protect the finished oil pastel and the copper mold, the extruder uses a non-metallic, hard pincer. The pincer rotates under the mechanical eccentric wheel, gently pressing the oil pastel out.
As the finished oil pastel falls, a conveyor belt installed at the bottom catches it and quickly transports it to the next line. The conveyor belt collects the material and delivers it to a stainless steel box.
A frequency converter controls the main drive motor, which drives the turntable via a reduction gearbox. The stirring switch and stirring motor form the stirring system, while the receiving/feeding switch, receiving/feeding regulator, and receiving/feeding motor form the receiving/feeding control system.
