Description

Technical Field

[0001] This application relates to the field of plastic pelletizing equipment technology, and in particular to a pelletizing and conveying device for plastic pelletizing equipment. Background Technology

[0002] Granulation equipment is a molding machine that can shape materials into specific shapes. It works by mixing plastic raw materials, heating and melting them inside the granulator, and then injecting the molten plastic material through a rotating screw to form a blank of the desired shape. After the blank is extruded, it needs to be granulated to obtain plastic pellets, which are then collected. Currently, after granulating the blank, granulators typically place a hopper at the bottom of the granulator to collect the plastic pellets. The hopper, filled with plastic pellets, is then manually transferred to the next process. This production method easily results in plastic pellets spilling onto the ground, hindering collection and exhibiting low levels of automation. Utility Model Content

[0004] Preferably, the extruder is provided with an extrusion die at the discharge end, and the pelletizing assembly includes a first driver and a cover disposed on the mounting frame. A rotating shaft is connected to the driving end of the first driver, and a plurality of cutters are disposed on the outer periphery of the rotating shaft facing the extrusion die.

Detailed Implementation

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example

[0014] To address the aforementioned technical problems, this embodiment provides a pelletizing and conveying device for a plastic pelletizing equipment, such as... Figure 1-2 As shown, the system includes an extruder 10, with a mounting frame 20 at the discharge end of the extruder 10. A pelletizing assembly 30 is mounted on the mounting frame 20. After the plastic is extruded by the extruder 10, it is cut into plastic pellets by the pelletizing assembly 30. A collecting assembly 40 is connected below the mounting frame 20. A collecting bin 50 connected to the collecting assembly 40 is located on one side of the extruder 10. The plastic pellets cut by the pelletizing assembly 30 fall into the collecting assembly 40 and are then conveyed to the collecting bin 50 by the collecting assembly 40. A feeding assembly 60 is located below the collecting bin 50 and conveys the plastic pellets in the collecting bin 50 to the next production process. This achieves automatic pelletizing, collection, and conveying of plastic pellets, eliminating the need for manual collection, improving the automation level of workshop production, and increasing production efficiency.

[0015] Specifically, the extruder 10 has an extrusion die 11 at its discharge end. The extrusion die 11 has multiple discharge holes. After the extruder 10 extrudes the plastic raw material from the extrusion die 11, the raw material is cut into pellets by the pelletizing assembly 30. Further, such as... Figure 3-4 As shown, the pelletizing assembly 30 includes a first driver 31 and a cover 32 mounted on the mounting frame 20. A rotating shaft 33 is connected to the driving end of the first driver 31, and a plurality of cutters 34 are arranged on the outer periphery of the rotating shaft 33 facing the discharge die head 11. For example, the first driver 31 can be a motor, which drives the rotating shaft 33 to rotate, thereby rotating the cutters 34 and cutting the extruded material from the discharge die head 11 into pellets. The cover 32 can prevent pellets from splashing and falling from the bottom of the cover 32 into the collection assembly 40. The mounting frame 20 is detachably connected to the extruder 10 via a connecting rod 21, which can be a bolt for easy disassembly.

[0016] Furthermore, a cylindrical block 331 is provided on the outer peripheral surface of the rotating shaft 33. The cylindrical block 331 has a groove for the cutter 34 to be inserted into, and the cutter 34 is movably disposed in the groove. Specifically, the cutter 34 has a waist-shaped groove 341, and a locking member 332 is provided on the side of the cylindrical block 331, which passes through the waist-shaped groove 341. The locking member 332 can be a screw. The locking member 332 is used to fix or loosen the cutter 34. Thus, the position of the cutter 34 in the groove can be adjusted through the waist-shaped groove 341, thereby adjusting the appropriate distance between the cutter 34 and the discharge hole of the discharge die head 11. In this way, the cutter 34 cuts the plastic blank extruded by the discharge die head 11 into plastic granules.

[0017] Furthermore, the material collection assembly 40 includes a first hopper 43 connected to the bottom of the cover 32 and a conveying pipe 42 connected to the bottom of the first hopper 43. A feeder 41 is connected to one end of the conveying pipe 42, and the other end of the conveying pipe 42 is connected to the collection box 50. After the pelletizing assembly 30 cuts the plastic blank into plastic pellets, the plastic pellets fall from the cover 32 into the first hopper 43, and then into the conveying pipe 42. The feeder 41 then conveys the plastic pellets in the conveying pipe 42 to the collection box 50. The feeder 41 can be a blower, which conveys the plastic pellets to the collection box 50. The feeder 41 can also be other devices that can convey plastic pellets to the collection box 50. This embodiment does not limit the type of feeder 41.

[0018] Furthermore, the feeding assembly 60 includes a housing 61, a second driver 63 disposed at one end of the housing 61, a second screw 62 connected to the second driver 63 disposed inside the housing 61, a second hopper 64 mounted on the housing 61 and located below the collection box 50, and a discharge port 65 opened at the bottom of the other end of the housing 61. For example, the second driver 63 can be a motor. Plastic granules in the collection box 50 fall into the second hopper 64, and then into the housing 61. The second screw 62 is then driven by the second driver 63 to rotate, thereby conveying the plastic granules forward to the next process, and finally discharging them through the discharge port 65 at the bottom of the housing 61. In some embodiments, a pipe and a suction device can be connected to the discharge port 65 to convey or pack the plastic granules at the discharge port 65. The top of the housing 61 has an opening, which provides ventilation and heat dissipation for the plastic granules during conveying.

[0019] In summary, the present application's solution features an installation frame at the extruder's discharge end, with a pelletizing component mounted on the frame. After the plastic is extruded into shape by the extruder, it is cut into plastic pellets by the pelletizing component. A collection component is connected below the installation frame, and a collection box connected to the collection component is located on one side of the extruder. The plastic pellets cut by the pelletizing component fall into the collection component, which then conveys them to the collection box. A feeding component is located below the collection box, which transports the plastic pellets from the collection box to the next production process. This achieves automatic pelletizing, collection, and conveying of plastic pellets, eliminating the need for manual collection, improving the automation level of workshop production, and increasing production efficiency.

[0020] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
