Description

Technical Field

[0001] The utility model relates to the technical field of acrylic plate production equipment, in particular to an exhaust type extruder. Background Art

[0002] Acrylic, also known as specially treated organic glass, is a replacement product of organic glass. Light boxes made of acrylic have good light transmission performance, pure color, rich colors, beautiful and smooth, taking into account both day and night effects, long service life, and no impact on use. Acrylic sheets will use extruders during production, and extruders are used to fully mix and extrude a variety of granular raw materials and output them. They are mainly used in the field of plastic or rubber manufacturing. When working, the extruder heats the raw materials to make them viscous and flow. Under pressure, it passes through a die with a certain shape and becomes a continuum with a cross-section similar to the shape of the die. Then, by cooling, the raw materials with a certain geometric shape and size are changed from a viscous state to a highly elastic state. Finally, they are cooled and shaped into a glass state to obtain the desired products. And the exhaust extruder refers to an extruder with an exhaust port in the middle of the barrel so that the air and volatiles in the processed plastic can be discharged. In the existing exhaust extruders, the feeding method is generally to use a feeding pipe to feed the material into the input port, but the amount of conveying and adding is not easy to control, and it is inconvenient to use.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0026] Specifically, the feed shell 200 is used to facilitate the conveying of materials into the interior of the exhaust type extruder body 100. When the materials enter the interior of the feed shell 200, an external hot air device is used in conjunction with a drying mechanism 400 to facilitate drying the conveyed materials. The feeding mechanism 300 is used to facilitate the uniform conveying of the dried materials into the interior of the exhaust type extruder body 100. The feeding mechanism 300 can convey materials into the exhaust type extruder body 100 in a regular and quantitative manner.
