Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to specific embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An extrusion head of a granulator is shown in figures 1 and 2 and comprises an extrusion head body 1, a plastic containing cavity 2, a glue removing containing piece 4 and an extrusion head 3. The extrusion head body 1 is internally provided with a plastic channel 11 and a plastic removing flow channel 12, wherein the plastic channel 11 is used for introducing plastic, and the plastic removing flow channel 12 is used for temporarily storing excessive plastic bodies so as to prevent the plastic bodies from reversely flowing to apply pressure to the extrusion head. It surrounds to move back gluey runner 12 plastic passageway 11 sets up, and plastic passageway 11 is separated with moving back gluey runner 12 with plastic passageway 11's lateral wall, avoids the plastic body directly to get into and moves back gluey passageway. The plastic containing cavity 2 is arranged at the output end of the extrusion head body 1 and communicated with the plastic channel 11, and the plastic containing cavity 2 can be used for loading and containing a plastic body flowing from the plastic channel 11 so as to extrude the plastic body. The extrusion head 3 is arranged at the output end of the plastic containing cavity 2 and is communicated with the plastic containing cavity 2, and the plastic body of the plastic containing cavity 2 is extruded from the extrusion head 3 under the pushing action of the plastic body which continuously flows into the plastic channel 11. The bottom cover of plastic passageway 11 is equipped with baffle 13, the outer fringe of baffle 13 is hugged closely the inner wall in plastic holding chamber 2, be equipped with the messenger on baffle 13 plastic holding chamber 2 with move back through-hole 14 of gluey runner 12 intercommunication, baffle 13 plays the effect of current-limiting, and on the one hand, baffle 13 separates most plastic body, avoids plastic holding chamber 2's colloid direct flow to advance to move back in gluey runner 12, and on the other hand, baffle 13's through-hole 14's aperture size can restrict the plastic flow that flows into and move back gluey runner 12, ensures that plastic holding chamber 2's plastic body has sufficient extrusion pressure. The glue removing containing part 4 is arranged on the extrusion head body 1 and is communicated with the glue removing flow channel 12, and the plastic body can enter the glue removing containing part 4 along the glue removing flow channel 12 for temporary storage.
Specifically, as shown in fig. 1 and fig. 2, when extruding, the extrusion head body 1 is connected with an external plastic source, the plastic body enters the plastic channel 11 from the outside and flows to the plastic accommodating cavity 2, when the plastic body in the plastic accommodating cavity 2 reaches a certain amount, the plastic body continuously flowing in from the plastic channel 11 pushes the plastic body in the plastic accommodating cavity 2 to extrude from the extrusion head 3, in the extrusion process, if the plastic body inside the extrusion head is excessive, the plastic body can enter the glue return flow channel 12 and temporarily store in the glue return accommodating part 4 through the through hole 14 of the partition plate 13, so that the situation that the reaction force is applied to the reverse flow by the plastic to cause the loosening of the extrusion head is avoided, the granulator can stably extrude the plastic, and the quality of the plastic is favorably ensured.
As shown in fig. 2, the extrusion head 3 includes an extrusion head housing 31 and a flow distribution block 33, the extrusion head housing 31 is hollow, the flow distribution block 33 is disposed inside the extrusion head housing 31, an extrusion channel 32 is reserved between the flow distribution block 33 and an inner wall of the extrusion head housing 31, and a cross section of the extrusion channel 32 is wedge-shaped, so that a plastic body can be uniformly extruded along the wedge-shaped extrusion channel 32.
In the extruder head of the pelletizer provided in this embodiment, as shown in fig. 1 and fig. 2, the glue removing container 4 is disposed at a distance from the upper end 1/3 of the extruder head body 1, so as to prevent the plastic in the extruder head from directly entering the glue removing container 4 when the amount of plastic is slightly excessive, and the glue removing flow channel 12 can be increased to increase the amount of temporarily stored plastic.
As shown in fig. 1, the glue removing container 4 is provided with a piston rod 6, the piston rod 6 is slidably connected in the glue removing container 4, when the plastic body is excessive, the plastic body can flow along the glue removing flow channel to the glue removing container 4 for temporary storage, when the plastic body volume is recovered to be normal, the plastic body exiting the glue removing container 4 flows back to the plastic containing cavity 2, and the piston rod 643 can be pushed to apply pressure to prevent the plastic body from remaining in the glue removing container 4.
In the extruder head of the pelletizer provided in this embodiment, as shown in fig. 1 and fig. 2, the glue removing container 4 is arranged obliquely upward, and the horizontal inclination angle of the glue removing container 4 ranges from 30 ° to 45 °, so that the plastic cement temporarily existing in the glue removing container 4 can rapidly flow back into the plastic container 2.
In the extruder head of the pelletizer provided in the embodiment, as shown in fig. 1 and fig. 2, the upper end of the extruder head body 1 is sleeved with the installation clamping piece 5, so that the extruder head is conveniently and fixedly installed on the pelletizer to be used, and the position stability is ensured.
The present invention has been further described with reference to specific embodiments, but it should be understood that the detailed description should not be construed as limiting the spirit and scope of the present invention, and various modifications made to the above-described embodiments by those of ordinary skill in the art after reading this specification are within the scope of the present invention.
