Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to an extrusion granulator for plastic products. Background Technology

[0002] An extrusion granulator for plastic products is a key piece of equipment in the plastics processing industry. It uses a rotating screw to transport, melt, and plasticize plastic raw materials within a barrel, transforming them into a homogeneous fluid. This fluid is then extruded through a specific die, cooled, and pelletized into uniformly sized plastic granules. This equipment boasts high production efficiency and stable granule quality, and is widely used in the raw material production stages of various plastic products.

[0003] Before most plastic products are extruded and granulated, the material needs to be fed from the hopper into the screw feed section. However, during feeding, the material is prone to clumping due to its high moisture content, which can cause blockage in the hopper and make it difficult to feed into the screw feed section. This prevents the extruder from working properly. Cleaning the blockage requires time and manpower, and even if production is resumed after cleaning, the overall production efficiency will be greatly reduced, increasing the production time and cost per unit product.

[0004] Therefore, it is necessary to provide a new type of extrusion granulator for plastic products to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an extrusion granulator for plastic products.

[0014] Compared with related technologies, the extrusion granulator for plastic products provided by this utility model has the following beneficial effects:

[0015] This invention features a rotating rod, a stirring roller, and a receiving trough within the hopper.

Its function is to transmit the power of the motor 10 to the rotating rod 4, thereby rotating the agitator roller 5 and agitating the material in the hopper 3.

[0027] The motor 10 is fixedly connected to the top right side of the carrying plate 1. The driving end of the motor 10 is fixedly connected to the driving bevel gear 11. The driven bevel gear 12 is fixedly connected to one side of the transmission assembly. The left end of the driving bevel gear 11 is fixedly connected to the auger column 13.

The end of the driven bevel gear 12 near the driven wheel 8 is rotatably connected to the inner front wall of the right side of the screw feed box 2. The driven bevel gear 12 is meshed with the auger column 13. The outer end of the auger column 13 near the driving bevel gear 11 is rotatably connected to the right side of the conveying chamber. The auger blade 14 is fixedly connected to the outer side of the auger column 13. The conveying chamber and support assembly are located at the left side of the screw feed box 2. The bottom end of the carrying plate 1 is equipped with a support assembly, which includes multiple support legs 15 and connecting rods 16. Multiple support legs 15 are fixedly connected at their top ends to the four corners of the bottom end of the carrying plate 1, and connecting rods 16 are fixedly connected to the adjacent sides of two support legs 15.

[0029] The working principle of the extrusion granulator for plastic products provided by this utility model is as follows:

[0030] The plastic material to be processed is poured into the hopper 3, and then the motor 10 is started. The drive end of the motor 10 drives the active bevel gear 11 to rotate. Through the transmission assembly, the rotation of the active bevel gear 11 transmits power to the driven bevel gear 12, causing the driven bevel gear 12 to drive the transmission assembly to move. This causes the driven wheel 8 to rotate, and under the rotation of the driven wheel 8, the drive wheel 7 is driven to rotate through the belt 9. Under the rotation of the drive wheel 7, the rotating rod 4 rotates. When the rotating rod 4 rotates, it drives the externally fixed stirring roller 5 to rotate on the inner wall of the hopper 3. During the rotation, the multiple receiving grooves 6 on the stirring roller 5 continuously tumble and stir the material in the hopper 3 to prevent the material from clumping due to high humidity and other reasons, ensuring that the material can flow smoothly.

[0031] As the drive bevel gear 11 rotates, it also drives the auger column 13 to rotate, and the auger blades 14 outside the auger column 13 rotate accordingly. The material, after being agitated by the stirring roller 5, enters the screw feed box 2 under the action of gravity and agitation. During rotation, the auger blades 14 convey the material from the right side to the left side of the screw feed box 2. The material is gradually pushed forward in the conveying chamber and transported by the auger blades 14 to the left side of the screw feed box 2, where it is discharged from the discharge port 17. A sealing groove 18 is provided at the discharge port 17, and a filter screen 19 is inserted into the sealing groove 18. During discharge, the material is filtered through the filter screen 19 to remove larger particles or insufficiently mixed lumps, ensuring the uniformity and purity of the extruded material. The material filtered through the filter screen 19 enters the discharge block 23. The discharge block 23 is connected to the screw feed box 2 via an assembly assembly. The right side of the mounting plate 22 is fixedly connected to the left side of the screw feed box 2, secured by screws 20 and nuts 21. Material is extruded from the discharge block 23 to form the desired product shape, and then fed into a water tank for cooling and molding. During the extrusion process, parameters such as the speed of the motor 10 can be adjusted according to actual production needs to control the extrusion speed and output of the material.
