Description

Technical Field

[0001] The utility model relates to the technical field of plastic extruders, in particular to a hopper of a plastic extruder. Background Art

[0002] The plastic extruder heats the plastic to make it in a viscous flow state, and under pressure, makes it pass through a die with a certain shape to become a continuum with a cross-section similar to the shape of the die. Then, by cooling, the plastic with a certain geometric shape and size changes from a viscous flow state to a highly elastic state, and finally cools and shapes it into a glassy state to obtain the desired product.

[0003] After searching, the Chinese patent authorization announcement number CN 203110293 U, announcement date August 7, 2013, discloses a plastic extruder hopper. The article states that "metal filters are installed in the middle and bottom of the hopper respectively; the mesh number of the metal filter I1 installed in the middle is greater than the mesh number of the metal filter II2 installed at the bottom; the filter hole area of ​​the metal filter I1 installed in the middle is greater than the filter hole area of ​​the metal filter II2 installed at the bottom." If the device is used for too long, a certain amount of dust and impurities will accumulate, affecting the quality of the raw materials, and the raw materials are easily adhered to the inner wall of the device, which is not convenient for cleaning and is prone to blockage, affecting the production speed of the plastic extruder. In view of this, in-depth research was conducted on the above-mentioned problems, and this case was created. Utility Model Content
