In order to further disclose the utility model, the principle and working process of the utility model are described below.

First heat the heating barrel 3, the temperature of the heating barrel 3 rises, when the barrel temperature reaches the point where the raw materials can be dissolved, start the stirring mechanism, pour the ground and formulated raw materials into the barrel for stirring and heating, after a certain period of time During the heating process, when the temperature of the raw material reaches 90 degrees C, the raw material becomes liquid. During the heating process, in order to make the temperature of the raw materials reach a balance, it is necessary to stir while heating. The stirring device can not only control the precipitation of the raw materials, but also effectively ensure the temperature balance.

Start the motor 2, and now the clutch 9 is in a disengaged state. After the temperature of other parts reaches the required temperature, the clutch 9 is merged, and the main engine starts to drive each transmission mechanism to start running.

The raw material becomes liquid after being heated. Driven by the motor 2, the piston rod 28 moves upwards to pump the raw material. The raw material is sucked into the delivery pipe 36 under the action of negative pressure, and enters the cavity of the valve body 31 through the pump valve 27. Inside.

The motor 2 drives the valve stem 29 to rotate an angle, and the valve stem 29 closes the inlet of the pump valve 27 and communicates the cavity in the valve body 31 with the outlet of the pump valve 27 . After completing this action, the piston rod 28 is pressed down to press the material. Under the pressure of the piston, the raw material flows out through the discharge port of the pump valve 27, and is injected into the oil pastel mold tube 21 through the injection port. During the forming process of the oil pastel, the air in the oil pastel mold tube 21 must be removed, and the method of pressing from the bottom to the top can completely overcome the problem of poor exhaust, and can make the raw materials in the oil pastel mold tube 21 full Under the action of mechanical eccentric wheel, the supply of raw materials and the size of the flow are carried out synchronously, and the raw materials are brought to the injection in an orderly manner.

Because the oil pastel raw material is a kind of chemical raw material that is easy to solidify when it is cold, after the raw material flows out through the heating barrel 3, if it is not heated, the raw material will be difficult to flow or even solidified as the temperature drops. Therefore, It is necessary to heat and insulate the pipeline through which the raw material flows. In this heat preservation environment, temperature is very important to the influence of raw material temperature on oil pastel raw materials. If the temperature is too high, the raw materials will deteriorate and even cause fire; if the temperature is too low, the oil pastel raw materials will produce gas and be difficult to flow. However, the utility model has heat-increasing settings on the pipelines where the raw materials flow and the parts that the raw materials pass through. It uses the high-temperature steam (or hot oil) circulating in the heating cycle to heat and keep the raw materials warm, so that the raw materials can be It can be turned into a liquid, which can ensure that the raw material does not undergo qualitative changes during the processing process, and can effectively control the standard temperature of the raw material in the production process. In the pipeline through which the raw material flows from the discharge to the injection process, the temperature of the raw material Guaranteed to be within the normal range.

After the piston presses the material once, that is, the oil pastel mold tube 21 has completed the pressure injection work, and the mold basin 5 starts to make a circular motion, driving the formed oil pastel to enter the next link.

After the liquid raw material was pressed into the oil pastel mold tube 21, the liquid raw material began to solidify under the effect of cooling water and became an oil pastel.

After the liquid raw material is solidified into the oil pastel, there is surplus material at the upper and lower ends of the oil pastel mold tube 21. If it is not cut off, the oil pastel is difficult to demould, and the two ends of the oil pastel are more uneven. Therefore, along with the rotation of the mold basin 5, when the solidified oil pastel reaches the cutting knife close to the upper surface and the lower surface of the mold basin 5, the remaining material at the upper and lower ends of the oil pastel mold tube 21 is then removed by the two cutting knives. Excision, and the incision is smooth. The two cutting knives not only play the role of cutting off the remaining material, but also play the impact of the ratchet 14 on the ratchet 15 .

After the oil pastel is cut, the oil pastel needs to be withdrawn from the oil pastel mold tube, that is, demoulding. Along with the rotation of mold basin 5, the oil painting stick that arrives at oil painting stick ejection mechanism 6 is ejected by the inserting rod on the oil painting stick ejection mechanism 6. In order not to damage the finished oil pastel and the copper mold, the oil pastel ejector mechanism 6 is a non-metallic hard skewer, which gently presses out the oil pastel under the rotation of the mechanical eccentric wheel.

When the extruded finished oil pastel falls down, the first conveyor belt installed at the bottom of the frame 1 will catch it and quickly send it to the second conveyor belt, and the second conveyor belt will convey it into the stainless steel inside the box.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
