Description

Technical Field

[0001] This utility model belongs to the field of plastic production technology, specifically relating to an automatic feeding two-stage extrusion granulation device. Background Technology

[0002] Plastic masterbatch is a special material for processing polymer materials. It is a concentrated form made by loading plastic additives into resin in an excessive amount. When used, it can be added in proportion to replace the direct addition of additives. Its core feature is that the additives are uniformly dispersed through a pre-mixing process, simplifying the plastic processing flow.

[0003] In extrusion granulation equipment, "two-stage" refers to a two-stage extrusion granulator, characterized by: First stage: high-speed mixing extrusion, achieving high shear and uniform mixing. Second stage: low-speed single-screw extrusion, avoiding over-shear and overheating. This two-stage separation design allows for more precise temperature control and mixing process. In existing technologies, most two-stage extrusion granulation devices are difficult to control during the mixing and extrusion processes. This makes it inconvenient to immediately feed the mixed plastic masterbatch into the next stage after mixing, and it is also inconvenient to adjust the size of the produced plastic masterbatch according to different granulation requirements during extrusion. To address these issues, we propose an automatic feeding two-stage extrusion granulation device. Utility Model Content

[0017] Please see Figures 1-5 This utility model provides an automatic feeding two-stage extrusion granulation device, including an extrusion component 1, a sealing component 3 and a cutting component 4 provided on the extrusion component 1, and a stirring component 2 provided on the sealing component 3; Extrusion assembly 1 includes an extrusion box 11, on which a feed chute and a discharge chute are provided; The sealing component 3 includes an intermediate box 31, which is disposed on the extrusion box 11. The intermediate box 31 has a hollow structure and is connected to the feed chute. A sliding groove is provided on the intermediate box 31, and a sealing plate 32 is provided in the sliding groove. A gear 34 is provided on the sealing plate 32, and an A rack 33 is provided on the intermediate box 31. The A gear 34 meshes with the A rack 33.

[0018] Specifically, during the granulation operation, the raw materials can be first put into the mixing component 2. The mixing component 2 can achieve rapid mixing of the raw materials. Then, the mixing component 2 can be connected to the extrusion component 1 through the sealing component 3, so that the mixed material can be put into the extrusion box 11 to complete the subsequent extrusion granulation operation. In use, the sealing plate 32 can be moved by rotating the gear A 34. The sealing plate 32 can be used to close and open the mixing box 21, so that the raw materials inside the mixing box 21 can be put into the extrusion box 11.

[0019] In this embodiment, the extrusion assembly 1 further includes a transfer roller 13, which is disposed inside the extrusion box 11. An A motor 14 is disposed on the extrusion box 11, and the output end of the A motor 14 passes through the surface of the extrusion box 11 and is connected to the end of the transfer roller 13. An extruded part 12 is disposed in the discharge trough.

[0020] Specifically, during use, motor A 14 can be started to drive the transmission roller 13 to rotate. The rotation of the transmission roller 13 can move the material, allowing it to move from the feed chute of the extrusion box 11 to the discharge chute, and then be extruded and granulated by the extruder 12. In this embodiment, the stirring assembly 2 includes a stirring tank 21, which is disposed on the intermediate tank 31 and has a hollowed-out lower end. A stirring roller 23 is disposed inside the stirring tank 21. A B motor 22 is disposed on the stirring tank 21, and the output end of the B motor 22 passes through the surface of the stirring tank 21 and is connected to the stirring roller 23. The stirring assembly 2 also includes a funnel 24. A funnel groove is opened on the stirring tank 21, and a funnel 24 is disposed inside the funnel groove. A conveyor belt 25 is disposed on the stirring tank 21, and the discharge end of the conveyor belt 25 is disposed above the funnel 24.

[0021] Specifically, when mixing materials, motor B 22 can be started to drive the mixing roller 23 to rotate, thereby mixing the materials inside the mixing tank 21. When feeding materials into the mixing tank 21, the external materials can be fed into the mixing tank 21 through the funnel 24 via the conveyor belt 25.

[0022] In this embodiment, the enclosure component 3 also includes a C motor 35, which is disposed on the enclosure plate 32. A gear A 34 is provided with a transmission shaft 36, and the transmission shaft 36 rotates through the surface of the enclosure plate 32. The output end of the C motor 35 is connected to the transmission shaft 36.

[0023] Specifically, during use, the C motor 35 can be started, which will drive the transmission shaft 36 to rotate, thereby driving the A gear 34 to rotate, thus moving the sealing plate 32. During use, the C motor 35 needs to be connected to the sealing plate 32 so that the C motor 35 can move synchronously when the sealing plate 32 moves.

[0024] In this embodiment, the cutting assembly 4 includes a cutting member 45. A limiting groove is formed on the extruder 12, and the cutting member 45 is disposed in the limiting groove. The end of the cutting member 45 is provided with a chamfer structure. The cutting assembly 4 also includes a B gear 42, which is disposed on the extruder 12. A B rack 43 is provided on the cutting member 45, and the B rack 43 meshes with the B gear 42. A D motor 41 is provided on the extruder 12, and the output end of the D motor 41 is connected to the B gear 42.

[0025] Specifically, during the granulation operation, after the extruder 12 extrudes the material, it needs to be cut to facilitate subsequent granulation. During cutting, the D motor 41 can be started to drive the B gear 42 to rotate, which in turn drives the B rack 43 and the cutting member 45 to move. At this time, the material can be cut by the chamfered structure at the end of the cutting member 45.

[0026] The working principle and usage process of this utility model are as follows: When performing granulation, the required materials are first fed into the mixing tank 21 through the funnel 24 via the conveyor belt 25. Then, the B motor 22 can be started to drive the mixing roller 23 to rotate at high speed, thereby achieving the mixing of materials.

[0027] After the materials are mixed, motor C 35 can be started to drive gear A 34 to rotate. The rotation of gear A 34 can drive the closing plate 32 to move outward. At this time, the intermediate box 31 is connected to the extrusion box 11. Since the lower end of the mixing box 21 is hollow, the mixing box 21 is connected to the extrusion box 11. The mixed materials inside the mixing box 21 will be put into the extrusion box 11. After the materials are put in, motor C 35 is started in reverse to reclose the intermediate box 31.

[0028] When the mixed material is fed into the extrusion box 11, the A motor 14 is started, which drives the transmission roller 13 to rotate. The rotation of the transmission roller 13 slowly moves the material from the feed chute of the extrusion box 11 to the discharge chute. By continuously moving the material to the discharge chute, the material can be evenly extruded through the extruder 12.

[0029] After the material is extruded, the D motor 41 can be started to drive the B gear 42 to rotate. When the B gear 42 rotates, it can drive the B rack 43 and the cutting member 45 to move. Through the movement of the cutting member 45, the material can be cut through the end of the cutting member 45, thereby completing the subsequent granulation. In use, the D motor 41 can be started in both forward and reverse directions in a regular manner so that the extruded material can be cut evenly.

[0030] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0031] To prevent dust or other debris from getting stuck between the gears and rack during use, a dustproof net can be installed around both.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
