Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a plastic particle feeding device for an extruder. Background Art

[0002] The extruder is an important plastic machine. The production and manufacturing of most plastic products can be achieved by extrusion molding. When the extruder production line is working, it is necessary to continuously transport the granular plastic to the material box of the extruder, so a feeding device is needed to feed the material. However, when the existing feeding equipment is in use, a large amount of material is stored inside the feeding equipment. When the material is discharged, the plastic particles generate static electricity due to mutual friction, and the electrostatic adsorption causes mutual agglomeration. The agglomeration causes the material to easily accumulate inside the discharge pipe of the feeding equipment during feeding, resulting in poor discharge of the plastic particles. It will also cause the plastic particles to be stuck inside the feeding equipment, and eventually cause the feeding equipment to stop feeding.

[0003] After searching, China disclosed a plastic particle feeding device for an extruder with patent publication number CN219405321U on July 25, 2023. It is roughly described as including an extruder body, a storage barrel fixedly provided on the extruder body through a support rod, the bottom of the storage barrel is fixedly connected to a vertical pipe, the lower end of the vertical pipe is fixedly connected to a horizontal pipe, the inner wall of the horizontal pipe is slidably connected to a thrust column, one end of the thrust column extends out of the outside of the horizontal pipe and is fixedly connected to a movable frame, the top and bottom walls of the movable frame are respectively fixedly provided with rack 1 and rack 2, a support plate is fixedly provided on the extruder body, a motor is fixedly provided on the support plate, the output end of the motor passes through the support plate and is fixedly connected to an incomplete gear, the incomplete gear is respectively engaged with rack 1 and rack 2, to ensure smooth discharge of plastic particles and prevent the feeding equipment from being stuck by plastic particles.
