[0002] The horizontal extruder is a key device in the field of plastic processing and forming. The fuselage is horizontally arranged. During operation, materials enter from the hopper and are gradually plasticized under the action of a heating device through the rotation, transportation, compression, and shearing of the screw. They are extruded into products such as pipes, profiles, and films through the die head of the machine head. The horizontal extruder has the advantages of uniform plasticization, high output, and good forming accuracy, and is widely used in the plastic processing industry.

[0032] Working principle of the present utility model:

[0033] When the discharge port of the hopper 2 of the horizontal mobile extruder is blocked by solid granular materials, take out the pull ring 313 from the storage bag 314. After taking it out, apply a vertically downward force to the pulling rope 37 through the pull ring 313. The pulling rope 37 will drive the knocking block 35 to move in the direction of the rope passing hole. During the above process, the return spring 36 will contract due to extrusion. When the knocking block 35 cannot move further under the limitation of the fixed box 31, remove the force applied to the pull ring 313. At this time, the knocking block 35 will make a return movement under the drive of the return spring 36 and hit the bottom end of the inner rod 33. The bottom end of the inner rod 33 being hit will drive the hopper 2 to vibrate. Then repeat the above steps until the discharge port of the hopper 2 is unblocked, which simplifies the operation and reduces the difficulty of the unblocking work.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
