Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious 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.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a plastic granules granulation is with automatic material mechanism of throwing, including extrusion case 8, the equal fixedly connected with backup pad 14 of 8 both sides outer walls of extrusion case, the inside of extrusion case 8 is provided with granulation mechanism, but the bottom of extrusion case 8 sets up the shutdown mechanism of horizontal slip, the top of extruding case 8 is provided with the power unit that is used for driving granulation mechanism operation, the outer wall of extruding case 8 is provided with the drive mechanism who is used for making shutdown mechanism horizontal slip, be provided with heat dissipation mechanism under the extrusion case 8, one of them outer wall of keeping away from drive mechanism's backup pad 14 is provided with flood dragon conveying mechanism, flood dragon conveying mechanism is prior art.

To carrying the plastic granules with fuse state to the inner chamber of extruding case 8 through flood dragon conveying mechanism, power unit drive granulation mechanism work is extruded the granulation to the plastic granules of fuse state, then drive mechanism orders about cutting mechanism work, then the plastic granules after the cutting gets into heat dissipation mechanism and cools off the heat dissipation.

Granulation mechanism includes

extrusion piece

5, and 5 sliding connection of extrusion piece are at the inner wall of extrusion case 8, and the inner chamber bottom of extruding case 8 is the array and has seted up die orifice 17, and extrusion case 8 is close to flood dragon conveying mechanism's outer wall and has seted up chute 16, and chute 16 is linked together with extrusion case 8's inner chamber, and also is linked together with flood dragon conveying mechanism.

Flood dragon conveying mechanism comes molten state plastics to carry the inner chamber that gets into extrusion case 8 through the chute 16 that is linked together, because the outer wall of extrusion piece 5 and the outer wall sliding connection who extrudes the case 8 and be close to the top, after the inner chamber of extrusion case 8 was full of molten state plastics, start hydraulic cylinder 2, be output shaft 3 exports downwards, make extrusion piece 5 can extrude the molten state plastics of the inside of extrusion case 8, then extrude the granulation downwards through last die orifice 17 that is linked together, through the hole shape that changes last die orifice 17, thereby change the shape of extruding the granule.

Furthermore, similarly, when the extrusion block 5 moves downwards, the chute 16 is blocked by the extrusion block 5 until the extrusion is completed, and the blockage is released by resetting, so that intermittent feeding of the molten plastic can be realized by up-and-down reciprocating of the extrusion block 5, and the supplementary plastic and the extrusion form a synergistic cooperation, so that the equivalent plastic particles can be extruded and granulated each time, and further, the granulation quality is uniform.

Further, the cutting mechanism comprises a transverse plate 19, the transverse plate 19 is located at the bottom of the extrusion box 8, the upper die opening 17 is connected between the two support plates 14 in a sliding mode, the top of the transverse plate 19 is provided with lower die openings 20 in an array mode, the lower die openings 20 are communicated with the upper die opening 17, and the inner diameters of the lower die openings 20 and the upper die opening 17 are consistent.

When the plastic granules in the molten state enter the upper die opening 17 and the lower die opening 20, the transverse plate 19 is moved to ensure that the upper die opening 17 is not communicated with the lower die opening 20, so that the extruded plastic granules in the molten state can be cut, and the equal length of all the cut plastic granules is ensured.

Further, power unit includes roof 1, and roof 1 is fixed on crossbeam or portal frame, and the bottom fixedly connected with pneumatic cylinder 2 of roof 1, the output fixedly connected with output shaft 3 of pneumatic cylinder 2, and the bottom of output shaft 3 and the top fixed connection of extrusion piece 5 realize reciprocating and reciprocate through the input output of control output shaft 3 to the realization is to the extrusion granulation of melt state plastic granules.

Further, drive mechanism includes connecting

plate

4, 4 fixed connection of connecting plate are at the outer wall of output shaft 3, the first rack 15 of bottom fixedly connected with of the one end of output shaft 3 is kept away from to connecting plate 4, the outer wall fixedly connected with bearing frame 22 of extrusion case 8, it is connected with gear 23 to rotate on the bearing frame 22, gear 23 is connected with the meshing of first rack 15, and the tooth of gear 23 with the same vertical face of first rack 15 is circumference tooth, the outer wall fixedly connected with second rack 24 that is close to first rack 15 of diaphragm 19, second rack 24 meshes with gear 23 mutually, and gear 23 and the tooth of the same vertical face of second rack 24 are fan-shaped and distribute.

When the output shaft 3 drives the extrusion block 5 to move downwards, the output shaft 3 can drive the first rack 15 to move downwards as well, because the meshing relation of the gear 23 and the first rack 15 is realized, the gear 23 can be driven to rotate clockwise, but the second rack 24 is not meshed with the gear 23 at the moment, the gear 23 can be meshed with the second rack 24 after rotating a certain angle, a delay effect is realized, the grain length of the extruded granules reaches the requirement, the gear 23 rotates to drive the second rack 24 to move for one end distance to the direction of the flood dragon conveying mechanism, the upper die opening 17 and the lower die opening 20 are not communicated, the extruded molten plastic granules are cut, and the equal length of all the cut plastic granules is ensured.

Further, heat dissipation mechanism includes cooling barrel 13, and cooling barrel 13 passes through installation piece fixed connection at the outer wall of backup pad 14, and cooling barrel 13 is located under die orifice 20, and the inner chamber bottom of cooling barrel 13 rotates and is connected with the pivot, and the outer wall fixedly connected with diaphragm of pivot, square hole 9 has been seted up to cooling barrel 13's outer wall, and discharge gate 11 has been seted up to cooling barrel 13's inner chamber bottom, and cooling barrel 13's top is provided with motor 12.

After the cutting process is accomplished, the molten state plastic granules after cutting off can get into the inside of cooling barrel 13, starter motor 12, make the pivot can drive square plate 21 and rotate, thereby pass through square hole 9 with the inside steam of cooling barrel 13 and discharge, thereby accelerate the cooling of molten state, can roll the plastic granules that is located cooling barrel 13 inside simultaneously, prevent to bond, also can accelerate the heat dissipation simultaneously, pass through discharge gate 11 flow with plastic granules and put into other processes rotating simultaneously.
