Technical Field

[0002] A granulator is a device used to make plastic granules. It is a device used to mix and heat multiple raw materials to make plastic granules for subsequent use. Multiple raw materials in granular, liquid or gel form are mixed and added to the granulator. The raw materials are heated, melted, stirred and mixed in the granulator, and then extruded and cooled in the granulator to form granules. Since the manufactured plastic granules are used in different scenarios, there are strict requirements on the ingredients and proportions. In order to make the performance exactly the same as the requirements, the quantitative amount of raw materials is very important when adding raw materials to the granulator.
[0003] A traditional granulator is provided with a conical funnel, and the granular raw materials are directly added into the hole after being weighed, and the raw materials enter the granulator under the action of gravity. This method is more suitable for dry granular raw materials, but in many cases, the raw materials used are colloidal viscous raw materials. It is difficult to make the raw materials enter the granulator evenly and at a uniform speed only by gravity or direct addition. At the same time, the colloidal raw materials enter the granulator without being extruded. Due to the different shapes of the colloidal raw materials, the amount of addition is difficult to control. Therefore, in order to make the colloidal raw materials can be quantitatively added to the extruder, we propose a quantitative feeding device and method for plastic granule production and processing.

[0012] A quantitative feeding method for the production and processing of plastic particles, using the above-mentioned quantitative feeding device for the production and processing of plastic particles, comprises the following steps: Step 1, adding raw materials: adding the raw materials into the stirring bin at the adding port, and the raw materials fall onto the two stirring cones; Step 2, driving stirring: the output end of the motor drives the second gear to rotate, the second gear drives the two first gears to rotate, the first gear drives the universal shaft structure to rotate, and the universal shaft structure drives the stirring cone to rotate; Step 3, stirring the raw materials: the two stirring cones drive the raw materials to stir, and the two stirring cones rotate in the same direction; Step 4, extruding the raw materials: the output ends of the plurality of driving cylinders 1 extend in sequence to push the raw materials in the mixing bin, and push the raw materials toward the filling nozzle; Step 5, raw material extrusion: the output end of the driving cylinder 2 is shortened to pull the shielding plate 1 to slide to the outside of the filling nozzle, and the raw material enters the filling nozzle; Step 6, quantitative measurement of raw materials: the raw materials enter the gap between the push block and the feed block through the filling nozzle, the raw materials push the feed block to slide upward in the quantitative frame, and the displacement sensor 1 and the displacement sensor 2 detect the moving distance of the feed block; Step seven, feeding into the granulator: when the amount of raw materials in the quantitative frame reaches the required amount, the output end of the driving cylinder 2 extends to push the baffle plate 1 into the filling nozzle, the output end of the driving cylinder 3 shortens to pull the baffle plate 2 to slide to the outside of the quantitative frame, and the output end of the driving cylinder 4 extends to push the feeding block to move, pushing the raw materials in the quantitative frame into the granulator.
[0013] The working principle and beneficial effects of the present invention are: 1.

In the present invention, by setting a feeding block and a driving cylinder 4, the arc on the lower side of the feeding block cooperates with the inner wall of the granulator, so that when the feeding block pushes the raw materials in the quantitative frame into the granulator, there will be no raw materials left in the feeding block and the quantitative frame, and the feeding block will not enter the granulator to affect the granulation process. When the raw materials enter the quantitative frame and push the feeding block to move, the displacement sensor 1 and the displacement sensor 2 simply measure the distance of the feeding block movement, and then judge the amount of raw materials entering the quantitative frame. When the shielding plate 1 slides and extends into the filling nozzle when the raw materials are pushed into the granulator, the raw materials cannot be pushed into the filling nozzle by the driving cylinder 4; 3. In the present invention, by setting a mixed extrusion mechanism, the raw materials can be stirred and extruded, making the raw materials more compact, avoiding the formation of special shapes that are difficult to quantify, and by setting a quantitative filling mechanism, the amount of raw materials fed into the granulator can be measured.

A quantitative feeding method for the production and processing of plastic particles, using the quantitative feeding device for the production and processing of plastic particles according to claim 9, characterized in that: The following steps are involved: S1, adding raw materials: adding raw materials into the stirring chamber (4) at the adding port (6), and the raw materials fall onto the two stirring cones (8); S2, driving stirring: the output end of the motor (7) drives the gear 2 (11) to rotate, the gear 2 (11) drives the two gears 1 (10) to rotate, the gear 1 (10) drives the universal shaft structure (9) to rotate, and the universal shaft structure (9) drives the stirring cone (8) to rotate; S3, stirring the raw materials: the two stirring cones (8) drive the raw materials to stir, and the two stirring cones (8) rotate in the same direction; S4, extruding raw materials: the output ends of the plurality of driving cylinders 1 (12) are extended in sequence to push the raw materials in the mixing bin (4), thereby pushing the raw materials toward the filling nozzle (15); S5, raw material extrusion: the output end of the second driving cylinder (18) is shortened to pull the first shielding plate (16) to slide to the outside of the filling nozzle (15), and the raw material enters the filling nozzle (15); S6, raw material quantitative measurement: the raw material enters the gap between the push block (13) and the feed block (21) through the filling nozzle (15), the raw material pushes the feed block (21) to slide upward in the quantitative frame (14), and the displacement sensor 1 (22) and the displacement sensor 2 (23) detect the moving distance of the feed block (21); S7, feeding into the granulator (2): when the amount of raw materials in the quantitative frame (14) reaches the required amount, the output end of the driving cylinder 2 (18) extends to push the baffle plate 1 (16) into the filling nozzle (15), the output end of the driving cylinder 3 (19) shortens to pull the baffle plate 2 (17) to slide to the outside of the quantitative frame (14), and the output end of the driving cylinder 4 (20) extends to push the feeding block (21) to move, thereby pushing the raw materials in the quantitative frame (14) into the granulator (2).
