Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulation technology, specifically a granulation device for biodegradable materials. Background Technology
[0002] Degradable materials are mainly classified into microbial degradable materials, photodegradable materials, chemical degradable materials, and biodegradable materials according to their degradation methods. Among them, biodegradable materials (such as PLA, PBS, PHA, etc.) have become a research hotspot in the field of environmental protection materials because they possess the mechanical properties of traditional polymer materials and can be decomposed into CO2 and water by microorganisms in the natural environment. In the research and development and production of biodegradable materials, granulators are one of the key pieces of equipment, mainly used to process molten or powdered raw materials into uniform particles for subsequent blown film, injection molding, or extrusion molding.
[0003] Currently, common granulators mainly include dry roller granulators, rotary drum granulators, and dry roller press granulators. These devices still have problems in the processing of biodegradable materials, such as fixed forming hole size, poor adaptability, and significant differences in melt flowability and viscosity among different biodegradable materials. However, traditional granulators usually use a fixed hole diameter design for the die head. If the particle size needs to be adjusted, the entire die head must be replaced after stopping the machine, which seriously affects production efficiency.
[0004] Based on this, a biodegradable material granulation device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] In one embodiment, such as Figures 1-4 As shown, a biodegradable material granulation device includes a feeding pipe 1, a feeding assembly is provided inside the feeding pipe 1, and a granulation assembly is provided on one side of the feeding pipe 1.
[0026] The granulation assembly includes a cutting box 10, one end of which is fixedly connected to one side of the feeding pipe 1. A discharge port 4 is fixedly connected to the lower surface of the cutting box 10. A limiting groove 14 is formed at the end of the cutting box 10 adjacent to the feeding pipe 1. A perforated forming plate 16 is slidably arranged inside the limiting groove 14. A sealing rubber gasket is provided inside the limiting groove 14. Several locking bolts 15 are arranged in an array on one side of the limiting groove 14. The locking bolts 15 are threadedly connected to the limiting groove 14 and the perforated forming plate 16. The diameter of the perforated forming plate 16 is adjustable from 3 to 8 mm and can be quickly disassembled and replaced by locking bolts 15. A cutting component is provided inside the cutting box 10.
[0027] In this embodiment, after the material is transported to the other end of the feeding pipe 1, it will be squeezed through the porous forming plate 16. At this time, the second motor 11 starts to drive the cutting blade 13 to rotate and cut the extruded material. At the same time, 17 also starts to rapidly cool the material particles. Then, the material particles leave the cutting box 10 through the discharge port 4 and are collected and stored. When it is necessary to change the size of the material particles, the locking bolt 15 is directly removed and the porous forming plate 16 is pulled out for replacement. The porous forming plate 16 of the corresponding size is placed inside the limiting groove 14 and then tightened by the locking bolt 15 to carry out the granulation process.
[0028] In one embodiment, such as Figure 4As shown, the cutting assembly includes a second motor 11, which is fixedly connected to one end of the cutting box 10. The output end of the second motor 11 passes through one side of the cutting box 10 and is fixedly connected to a transmission rod 12. Several cutting blades 13 are fixedly connected in an array to one end of the transmission rod 12 near the porous forming plate 16. When the second motor 11 is started, it drives the cutting blades 13 to rotate and cut the extruded material.
[0029] In one embodiment, such as Figure 4 As shown, a cooling assembly is provided on the upper side of the cutting box 10 to cool the material particles.
[0030] In one embodiment, such as Figure 4 As shown, the cooling assembly includes a vortex tube cooler 17, which is fixedly connected to one side of the cutting box 10. The vortex tube cooler 17 consists of a throttle valve, a filter, a pressure regulating valve, and an air inlet. The air inlet end of the vortex tube cooler 17 is connected to an external compressed air system. A vortex tube 18 is fixedly connected to one end of the vortex tube cooler 17. One end of the vortex tube 18 is inserted through the inside of the cutting box 10 and is fixedly connected to a nozzle. The vortex tube cooler 17 is also activated, and cold air is ejected through the nozzle of the vortex tube 18 to begin rapidly cooling the material particles.
[0031] In one embodiment, such as Figure 3 As shown, the feeding assembly includes a first motor 6, which is fixedly connected to one end of the feeding pipe 1. The output end of the first motor 6 passes through one side of the feeding pipe 1 and is fixedly connected to a screw feeder 7. A feed inlet 3 is fixedly connected to the upper surface of one end of the feeding pipe 1. The material enters the inside of the feeding pipe 1 through the feed inlet 3, and then the first motor 6 starts to drive the screw feeder 7 to rotate, and the material is fed at a uniform speed.
[0032] In one embodiment, such as Figure 3 As shown, a constant temperature component is provided on the outside of the feeding pipe 1 to ensure that the material temperature is constant and to prevent cooling and blockage of the feeding pipe 1.
[0033] In one embodiment, such as Figure 3 As shown, the constant temperature assembly includes a constant temperature sleeve 5, which is disposed on the outside of the feeding pipe 1. A heater 8 is fixedly connected to the outside of the constant temperature sleeve 5, and a heating tube 9 is disposed on the inside of the constant temperature sleeve 5. The two ends of the heating tube 9 are fixedly connected to the output end of the heater 8, and the heating tube 9 is arranged around the outside of the feeding pipe 1. When the heater 8 is activated, it transfers heat to the heating tube 9 to start constant temperature control of the material temperature inside the feeding pipe 1, ensuring that the material does not cool down and block the inside of the feeding pipe 1.
[0034] In one embodiment, such as Figure 1As shown, several bases 2 are fixedly connected to the outside of the thermostatic sleeve 5 to support the main body of the device.
[0035] The above embodiment discloses a biodegradable material granulation device. In this device, the material enters the feeding pipe 1 through the inlet 3. Then, the first motor 6 starts and drives the screw feeder 7 to rotate, and the material is fed at a constant speed. At the same time, the heater 8 starts and transfers heat to the heating tube 9 to keep the material temperature inside the feeding pipe 1 constant, ensuring that the material does not cool and block the inside of the feeding pipe 1. After the material is transported to the other end of the feeding pipe 1, it will be squeezed through the porous forming plate 16. At this time, the second motor 11 starts and drives the cutting blade 13 to rotate, cutting the extruded material. At the same time, the vortex tube cooler 17 also starts to quickly cool the material particles. Then, the material leaves the cutting box 10 through the outlet 4 and is collected and stored. When it is necessary to change the size of the material particles, the locking bolt 15 is removed and the porous forming plate 16 is pulled out for replacement. The porous forming plate 16 of the corresponding size is placed inside the limiting groove 14 and then tightened by the locking bolt 15 to start a new granulation process.
