Technical Field
[0001] The utility model belongs to the technical field of extruders, and in particular relates to a novel boom head. Background Art
[0002] The die head is crucial to whether a co-rotating twin-screw extruder can produce qualified products. In high-torque models, the die head needs to be widened to meet the production requirements. However, in the prior art, after the die head is widened, the discharge channel is easily widened, which causes the heat dissipation on both sides of the discharge channel to be faster than the middle, resulting in the temperature on both sides being lower than the middle. It is also easy for the flow channels on both sides to be longer than the middle and the friction of the flow channels on both sides to be greater than that in the middle. These factors easily cause the flow rate on both sides of the die head to be slower than that in the middle, making it inconvenient to use the widened die head. Utility Model Content
