The invention relates to the field of extrusion molding, and specifically proposes an extrusion device for a three-screw puffing device, comprising a three-screw extruding mechanism. There is a rotating sleeve, the outer wall of the rotating sleeve is provided with a spiral groove extending along the axial direction of the rotating sleeve, the anti-rotation core sleeve is provided with a transmission protrusion, the outer circumference of the anti-rotation core sleeve is provided with a support shell, and the support shell is provided with One-way valve, a first elastic member is arranged between the support shell and the anti-rotation core sleeve to make the anti-rotation core sleeve move away from the support shell, and one end of the support shell and the anti-rotation core sleeve is provided with a first elastic member. There is a first sealing ring, a second sealing ring is arranged between the other end and the screw, a third sealing ring is arranged between the anti-rotation core sleeve and the rotating sleeve, and a fourth sealing ring is arranged between the rotating sleeve and the screw The ring is used to solve the technical problem of stuck between the rotating sleeve and the screw due to corrosion.
Description
technical field [0001] The invention relates to the field of extrusion molding, in particular to an extrusion device for a three-screw puffing device. Background technique [0002] The puffing device belongs to a kind of equipment for processing puffed food, such as processing rice, corn, soybean, wheat, etc. in daily life. Its main working principle is that mechanical energy is converted into heat energy, and the food is squeezed and cooked by the heat generated when the machine is turned. The most obvious feature of the puffed food is that the volume becomes larger. [0003] The core structure of the puffing device is the extrusion equipment. In the prior art, an invention patent named "Three-screw Extrusion Mechanism for Puffing Machine" with the application publication number of CN108851151A and the application publication date of 2018.11.23 has been disclosed, including three The screw parts arranged in an equilateral triangle shape are arranged in parallel between adj...
