Description

Technical Field

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

[0002] During the plastic injection molding process, the plastic parts used for injection molding usually need to mix plastic particles of different colors, shapes, and compositions together. Traditional methods mostly use manual weighing, which will produce various errors. The weight ratio of each component does not meet the production process requirements, resulting in the injection molded plastic parts failing to meet the requirements of relevant technical standards. Therefore, the manufacturer has designed a plastic particle mixer. The existing plastic particle mixer mainly consists of multiple hoppers, weighing hoppers, and mixing bins. The multiple hoppers are filled with different plastic particles. The multiple hoppers fall into the weighing hopper, and are weighed by the weighing hopper. After being weighed by the weighing hopper, they are sent to the mixing bin for mixing. Although the existing plastic particle mixer can realize the weighing and mixing functions, the existing plastic particle mixer still has the following shortcomings:

[0003] 1) To mix plastic particles of different colors, shapes and compositions, multiple hoppers are required, which increases the cost of the hoppers and also increases the space occupied by the hoppers;

[0004] 2) When multiple hoppers fall into the weighing hopper, it is inconvenient to interrupt the unloading process, control the unloading process of the hopper, and control the unloading weight of plastic particles of different components. This may easily lead to the weight ratio of the plastic particles not meeting the production process requirements, thereby affecting the quality of injection molded plastic parts.

[0042] The weight of the plastic pellets to be discharged can be set through the touch screen 44. The Siemens PLC226 sends the plastic pellet discharge weight signal set on the touch screen 44 to the single-chip microcomputer. The Siemens PLC226 sends a signal to the solenoid valve, which controls the discharge slide cylinder 32 to retract, thereby driving the discharge slide 33 to move outward, so that the discharge port 31 is opened, and the plastic pellets fall into the weighing bucket 51. The weighing sensor 52 outside the weighing bucket 51 will collect the weight signal of the plastic pellets falling into the weighing bucket 51. The weight signal is transmitted to the A / D conversion module and the signal amplification module and then collected by the single chip microcomputer. When the weight collected by the single chip microcomputer reaches the set discharge weight of the plastic particles, the single chip microcomputer sends a signal to the Siemens PLC226, and the Siemens PLC226 sends a signal to the solenoid valve. The solenoid valve can control the discharge slide cylinder 32 to extend so as to drive the discharge slide 33 to move inward, so that the discharge port 31 is closed and the discharge of plastic particles is stopped, so as to avoid the continuous discharge of plastic particles affecting the actual mixing weight required by the plastic particles.

The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
