Description

Technical Field

[0001] This invention belongs to the field of track granule production, specifically relating to a TPE plastic track granule and its production equipment and process. Background Technology

[0002] Thermoplastic elastomers (TPE / TPR), also known as synthetic rubber or artificial rubber, possess the excellent properties of traditional cross-linked vulcanized rubber, including high elasticity, aging resistance, and oil resistance, while also offering the ease of processing and wide range of processing methods found in ordinary plastics. They can be produced using injection molding, extrusion, blow molding, and other processing methods, and the scraps can be 100% reused directly after being crushed. This simplifies the processing process and reduces costs, making TPE / TPR materials the latest material to replace traditional rubber.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: A type of TPE plastic running track granules, wherein the granules are prisms with a triangular cross-section. This design, with its triangular prism shape, offers several advantages over round or other shaped granules: The triangular prism shape increases the friction between granules, improving the track's grip and anti-slip properties. It reduces gaps between granules, increasing the track's density and durability. It reduces surface reflectivity, minimizing eye irritation and impact. Finally, it increases the surface area of ​​the granules, improving breathability and comfort.

[0028] Example 2, as Figures 1-8 As shown, a production device for TPE plastic track granules includes a circulating water tank 1, which includes a cooling tank 4. The cooling tank 4 has an extrusion head mounting hole 13. An extrusion head 2 is positioned above the extrusion head mounting hole 13. A cutting rotating ring 21 is movably mounted on the side of the extrusion head 2 near the extrusion head mounting hole 13. The extrusion head 2 has multiple circumferentially distributed discharge holes 22. A rotating blade holder 23 is movably mounted on the cutting rotating ring 21. The rotating blade holder 23 has circumferentially distributed cutting blade mounting grooves 24 at its end near the cooling tank 4. Cutting blades 25 are installed in the cutting blade mounting grooves 24. Cooling water is provided in the cooling tank 4. With this design, TPE plastic is extruded from the discharge holes 22, and the rotation of the cutting rotating ring 21 cooperates with the rotation of the extrusion head 22. The cutting blades 25 on the blade holder 23 cut the TPE plastic. Multiple cutting blades 25 are provided on the rotating blade holder 23 so that when the cutting quality decreases due to wear and excessive fine particles are produced, the blades can be replaced by rotating the blade holder 23, thus ensuring a better cutting effect. Furthermore, by providing multiple cutting blades 25 on the rotating blade holder 23, the problem of low production efficiency caused by the difficulty in replacing cutting blades in underwater pelletizing devices and excessive replacement frequency can be avoided. Additionally, the rotation time of the rotating blade holder 23 can be set to periodically replace the working cutting blades 25, preventing the blades from overheating due to prolonged operation, which would reduce cutting quality and shorten their lifespan.

[0029] Furthermore, the cutting rotating ring 21 can be movably installed in the annular mounting groove opened on the extrusion head 2. The cutting rotating ring 21 can be driven by a ring gear in conjunction with a motor, or it can be directly driven by a brushless motor. The rotating blade holder 23 is movably installed on the cutting rotating ring 21 through a mounting shaft. The rotating blade holder 23 can be driven by a ring gear in conjunction with a motor, or it can be directly driven by a motor.

[0030] In some disclosures, the cutting rotating ring 21 is provided with two circumferentially distributed rotating blade holders 23. This design can ensure the dynamic balance and force balance of the cutting rotating ring 21 during rotation, and ensure the stability of the rotational motion of the cutting rotating ring 21, thereby ensuring the consistency of the cutting blade 25 in cutting particles.

[0031] In some disclosures, the discharge hole 22 has a triangular cross-section. This design results in TPE granules with a triangular columnar cross-section. Compared to round or other shaped granules, the triangular columnar shape can increase the friction between granules, improving the track's grip and anti-slip properties; it can reduce the gaps between granules, improving the track's density and durability; it can reduce the reflectivity of the granule surface, reducing the track's irritation and impact on the eyes; and it can increase the granule surface area, improving the track's breathability and comfort.

[0032] Furthermore, the cross-section of the discharge hole 22 can be circular, polygonal, or other different shapes, thus obtaining TPE particles of different shapes.

[0033] In some disclosures, the cooling tank 4 has a first opening slot 44 and a second opening slot 45 on its side. The first opening slot 44 is connected to the first circulation section 14 through a water outlet connection section 11, and the second opening slot 45 is connected to the second circulation section 15 through a water inlet connection section 12. The first circulation section 14 and the second circulation section 15 are interconnected. A water circulation driving device 18 is provided in the second circulation section 15. With this design, the cooling water in the circulating water tank 1 can be circulated by the water circulation driving device 18. Cold water enters the cooling tank 4 from the water inlet connection section 12. After cooling the particles and the cutting tool, the warm water passes through the water outlet connection section 11, the first circulation section 14 and the second circulation section 15 to be cooled and then enters the cooling tank 4 from the water inlet connection section 12. This ensures the water temperature in the cooling tank 4 and thus ensures the cooling effect of underwater cutting.

[0034] Furthermore, the water circulation driving device 18 can use rotating helical blades to drive the water flow in the circulating water tank 1 to circulate;

[0035] Furthermore, the circulating water tank 1 is equipped with a cooling device, which can be a heat sink or a compressor for cooling and heat dissipation, thereby ensuring the water temperature in the cooling tank 4.

[0036] In some disclosures, the cooling tank 4 is provided with a filter cover 5, and the side of the filter cover 5 is provided with a side enclosure 7. The side enclosure 7 is provided with filter holes 71, and the opening direction of the filter holes 71 is facing the first opening groove 44. With this design, the cut particles can be made to flow into the first opening groove 44 due to the action of water flow, which makes it convenient to collect the particles.

[0037] In some disclosures, the inner side of the cooling tank 4 is provided with a first gear 43, the second opening slot 45 is provided with a movable baffle 6, the movable baffle 6 is provided with a third through hole 64, and the main shaft of the filter cover 5 is connected to a power motor. With this design, the filter effect of the movable baffle 6 first ensures that the particles will not enter the water inlet connection section 12. At the same time, the rotation of the filter cover 5 can drive the cut particles to rotate. In this way, the density of the particles is greater than that of water, and they will move outward with the rotation. This makes it convenient for the cut particles to flow quickly to the water outlet connection section 11 to avoid accumulation.

[0038] Furthermore, the filter cover 5 can be driven by a motor via a ring gear or belt, or it can be driven directly by a motor. Furthermore, the filter cover 5 is provided with a gear clearance groove 53 for accommodating the first gear 43.

[0039] In some disclosures, the filter cover 5 has a mounting beam 54 on its side, and multiple meshing second gears 55 are mounted on the mounting beam 54. The outermost second gear 55 meshes with the first gear 43. A return pipe 56 is located below the second gear 55. The return pipe 56 has circumferentially distributed stirring rods 58 and a first through hole 57. The upper end of the return pipe 56 is connected to a fine particle recovery pipe through a pipe. With this design, the rotation of the filter cover 5, in conjunction with the filter holes 71, can throw out the fine particles generated by cutting through the holes 71, thus avoiding the impact of inconsistent particle size on the laying quality. At the same time, the rotation of the filter cover 5, through the meshing of the outermost second gear 55 with the first gear 43, drives the second gear 55 to rotate. The rotation of the second gear 55, through the stirring rods 58, disturbs the water flow to prevent fine particles from settling to the bottom. The fine particles enter the return pipe 56 through the first through hole 57 and are transported by a suction pipe to complete the collection for secondary use. This design not only avoids inconsistent particle size but also collects the unusable particles separated out simultaneously.

[0040] Furthermore, the return pipe 56 is equipped with spiral blades, which can further enhance its ability to lift fine particles instead of simply relying on suction to simultaneously suck up the mixture of particles and water.

[0041] In some disclosures, the filter cover 5 has an outer annular mesh 51 on its outer side, and a first mounting groove 41 is opened on the side of the cooling tank 4 near the second opening groove 45. A movable baffle 6 is movably installed inside the groove, and a mounting boss 61 is provided on the back of the movable baffle 6. A second mounting groove 42 is opened inside the first mounting groove 41, and the mounting boss 61 is movably installed in the second mounting groove 42. An elastic telescopic member 62 is provided between the mounting boss 61 and the second mounting groove 42. A first gear 43 is opened at the end of the movable baffle 6 away from the second opening groove 45, and an elastic abutment post 52 is provided at the front end of the filter cover 5. Through this design, a fine particle collection groove is first formed by the cooperation of the outer annular mesh 51 and the side enclosure 7, and at the same time, by setting... The movable baffle 6 can prevent the water flow in the second opening slot 45 from being obstructed. When the filter cover 5 rotates, the gear clearance slot 53 engages with the abutment movement slot 63, driving the movable baffle 6 to move forward against the elastic force of the elastic telescopic member 62. When the opening position of the side enclosure 7 passes the second opening slot 45, the movable baffle 6 is blocked forward by the step. As the filter cover 5 continues to rotate, the elastic abutment column 52 overcomes its own elastic force and extends backward to release the engagement with the abutment movement slot 63. Thus, the movable baffle 6 returns to its original position under the action of the elastic telescopic member 62. This avoids the problem of water flow in the water inlet connection section 12 being obstructed from entering the cooling tank 4 due to the long-term double-layer separation between the movable baffle 6 and the outer ring mesh 51.

[0042] Furthermore, the elastic telescopic member 62 can be elastic rubber or a spring, the movable baffle 6 can be driven by a cylinder, motor or lead screw to complete the reciprocating motion, and the elastic abutment post 52 can complete the reciprocating motion by spring and boss.

[0043] Furthermore, to prevent clogging of the mesh, a dredging device is installed on the mesh. This dredging device can employ the following methods: A vibrating motor or vibrating rod is installed above or below the mesh and connected to it. This vibrates the mesh periodically or in real-time, applying vibrations of a certain frequency and amplitude. The mechanical effect of the vibration dislodges the fine particles adhering to the mesh. Alternatively, a nozzle or fan is installed above or below the mesh and connected to a water pump or air pump. This sprays water or air at a certain pressure and flow rate onto the mesh periodically or in real-time, using the dynamic effect of the water or air flow to blow away the fine particles. Finally, an ultrasonic generator or electromagnet is installed above or below the mesh and connected to it. This applies ultrasonic or electromagnetic waves of a certain frequency and intensity to the mesh periodically or in real-time, using the physical effect of the ultrasonic or electromagnetic waves to peel away the fine particles adhering to the mesh.

[0044] In some disclosures, the first circulation section 14 is provided with a transport connecting block 3, the upper end of which is provided with a transport connecting groove 31, which is connected to the water outlet connecting section 11. A water passage hole 35 is opened on the side of the transport connecting block 3, and a particle transport pipe 36 is provided on the side of the transport connecting block 3. A transport rotating shaft 32 is movably installed inside the transport connecting block 3, and a transport spiral blade 33 is provided on the transport rotating shaft 32. The particle transport pipe 36 is connected to the discharge port 16, and a water inlet 17 is provided on the second circulation section 15. With this design, the particles enter the transport connecting block 3 from the water outlet connecting section 11, are transported by the transport spiral blade 33, and are discharged from the discharge port 16. At the same time, cold water flows into the second circulation section 15 from the water inlet 17 to replenish the cooling water flowing out of the discharge port 16 from the circulating water tank 1, which facilitates the collection of particles.

[0045] In some disclosures, the transport spiral blade 33 is provided with multiple circumferentially distributed drainage grooves 34. This design can reduce the moisture content at the outlet 16. Furthermore, the outlet 16 and the particle transport pipe 36 are inclined so that the outlet of the outlet 16 is higher than the water surface of the circulating water tank 1, which can further reduce the moisture content of the material discharged from the outlet 16.

[0046] Working principle:

[0047] In this invention, TPE plastic is extruded from the discharge hole 22. The TPE plastic is cut by the rotation of the cutting rotating ring 21 in conjunction with the cutting blades 25 on the rotating blade holder 23. The rotating blade holder 23 has multiple cutting blades 25, allowing for replacement of the cutting blades 25 when wear leads to decreased cutting quality and an excessive number of fine particles. This ensures a better cutting effect. Furthermore, the multiple cutting blades 25 on the rotating blade holder 23 avoid the problem of low production efficiency caused by frequent blade replacements in underwater pelletizing devices. The rotation time of the rotating blade holder 23 can be set to periodically replace the cutting blades 25, preventing overheating from prolonged operation that could reduce cutting quality and shorten the blades' lifespan.
