Description

Technical Field

[0001] The present disclosure generally relates to the field of material recycling technology. More specifically, the present disclosure relates to a waste polyester fiber regeneration extrusion device and extrusion equipment. Background Art

[0002] Polyester fiber, commonly known as "terylene," is used in significant quantities in daily life and industrial production. However, this use generates a significant amount of waste polyester fiber. Current recycling methods typically involve cleaning and crushing the waste polyester fiber, then adding raw materials to the mix. The waste is then melted, extruded into strips, cooled, and pelletized to create granular, semi-finished materials. However, current polyester fiber recycling equipment is often only capable of producing materials with a single outer diameter. Producing materials with different outer diameters requires replacing the equipment, which is cost-effective and inefficient.

[0003] In view of this, there is an urgent need to provide an extrusion device for regenerating waste polyester fibers so that the polyester fiber discharge holes can be switched and recycled polyester fiber materials with various outer diameters can be produced through one device.

[0021] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1 and Figure 2 , Figure 1 An exemplary perspective view of a waste polyester fiber regeneration extrusion device according to some embodiments of the present disclosure is shown; Figure 2 An exemplary cross-sectional view of a waste polyester fiber regeneration extrusion device according to some embodiments of the present disclosure is shown. In some embodiments, the waste polyester fiber regeneration extrusion device 100 may include, for example, an extrusion barrel 2, which may be in the shape of a hollow cylinder with its axis arranged in a horizontal direction. The extrusion barrel 2 is provided with an inlet 21 and a discharge port 211. The inlet 21 may be provided, for example, on the vertical upper side of the extrusion barrel 2, near the first axial end of the extrusion barrel 2. The discharge port 211 may be provided on the vertical lower side of the extrusion barrel 2, near the second axial end opposite to the first axial end. The inlet 21 and the discharge port 211 are respectively connected to the extrusion cavity 20 inside the extrusion barrel 2, so that material can be input into the extrusion cavity 20 from the inlet 21, and the material can be discharged from the extrusion cavity 20 through the discharge port 211.

[0023] See also Figure 3 , Figure 3 Shown Figure 2The enlarged schematic diagram of part D in the figure. The first axial end of the extrusion barrel 2 can also be connected to an extrusion drive member, which can include an extrusion blade 25 extending into the interior of the extrusion barrel 2, and a drive actuator 23 fixed to the first axial end and capable of driving the extrusion blade 25 to rotate. The drive actuator 23 can also be fixedly connected to a fixed frame 231, which is also fixedly connected to the side wall of the extrusion barrel 2. The drive actuator 23 can, for example, be a drive output mechanism such as a rotary motor or a rotary cylinder, which is used to provide the extrusion blade 25 with a driving force to rotate it. For example, a connecting hole 26 for the drive shaft of the drive actuator 23 to pass through can be provided on the end face of the first axial end of the extrusion barrel 2, so that the drive shaft can extend into the interior of the extrusion cavity 20 and be fixedly connected to the extrusion blade 25. The extrusion blade 25 may be, for example, a spiral blade arranged along the axis of the extrusion barrel 2. The spiral blade rotates from the first axial end toward the second axial end, so as to push the melted material from the inlet 21 toward the outlet 211. In the extrusion barrel 2, the melted material can be mixed, extruded, and transported from the inlet 21 to the outlet 211.

[0024] In addition, a rotatable multi-position material tray 3 can be provided on the vertical lower side of the extrusion barrel 2, and the multi-position material tray 3 can, for example, have a plurality of support rods 331 arranged radially. One end of each of the plurality of support rods 331 is fixedly connected to each other at the center position of the multi-position material tray 3, and the other end of each support rod 331 is respectively provided with an extrusion tray 32. The extrusion tray 32 can, for example, be formed into a roughly disc-shaped shape, and a plurality of through-extrusion holes are provided on its axial end face. The multi-position material tray 3 can, for example, be rotatably connected to the vertical lower side of the extrusion barrel 2, so that the rotation of the multi-position material tray 3 can drive one of the plurality of extrusion trays 32 to move to align with the discharge port 211, so that the material extruded from the discharge port 211 is extruded through the extrusion holes on the extrusion tray 32.

[0025] See also Figure 4 and Figure 5 , Figure 4 Shown Figure 1 A magnified schematic diagram of part A; Figure 5 Shown Figure 2An enlarged schematic diagram of section B in FIG. In some embodiments, a switching mount 24 extending vertically downward may be provided on the side surface of the vertical lower side of the extrusion barrel 2. The switching mount 24 may, for example, be roughly cylindrical, with its axis arranged in the vertical direction. The central portion of the multi-position material tray 3 may be rotatably connected to the vertical lower end of the switching mount 24. Furthermore, the multi-position material tray 3 may be connected to the switching mount 24 in a manner that allows vertical movement. For example, the switching mount 24 may be fixedly connected to a switching spring 242. The switching spring 242 may be arranged in the vertical direction, with one end fixedly connected to the switching mount 24 and the other end connected to a spring fixing member 243 in the central portion of the multi-position material tray 3. This allows the multi-position material tray 3 to not only rotate relative to the mount to switch the extrusion tray 32 opposite the discharge port 211 of the extrusion barrel 2, but also to move relative to the switching mount 24 in the vertical direction. This improves the flexibility of the multi-position material tray 3 and facilitates the installation and adjustment of the extrusion tray 32.

[0026] Furthermore, the switching mount 24 may further include a spring slot 241 extending vertically upward from the lower end surface of the switching mount 24. The switching spring 242 may be disposed within the spring slot 241. The spring retainer 243 may also at least partially extend into the spring slot 241 and mate with the spring slot 241 in shape, thereby being guided by the spring slot 241. For example, the spring slot 241 may be circular in cross-section, while the spring retainer 243 may be cylindrical with a diameter similar to that of the spring slot 241. Thus, the portion of the spring retainer 243 located within the spring slot 241 is guided by the spring slot 241, ensuring that the multiple material trays 32 move along a fixed circular trajectory when the multiple material trays 3 are moved or rotated, thereby preventing misalignment between the material trays 32 and the discharge port 211 due to horizontal errors.

[0027] Also, see Figure 6 , Figure 6An exemplary perspective view of the feed tray body of the waste polyester fiber regeneration and extrusion device according to some embodiments of the present disclosure is shown. In some embodiments, the multi-position feed tray 3 can be a split structure. For example, it can include a rotating shaft 244 and a feed tray body 33 that rotates around the rotating shaft 244. The rotating shaft 244 can include, for example, a generally cylindrical shaft and a flanged retaining plate 245 disposed at one axial end of the shaft. The feed tray body 33 can include a plurality of radially arranged support rods 331 and a plurality of extrusion trays 32 fixedly connected to the ends of the support rods 331. The center portion of the feed tray body 33 is provided with a feed tray shaft hole 311 extending vertically therethrough. The shaft portion of the rotating shaft 244 can pass through the feed tray shaft hole 311 and be fixedly connected to the axial end of the spring retainer 243. The flanged retaining plate 245 of the rotating shaft 244 can be disposed vertically below the feed tray shaft hole 311. The diameter of the flanged retaining plate 245 can be set to be larger than the diameter of the tray shaft hole 311 , so that the flanged retaining plate 245 can limit the position of the tray body 33 in the vertical direction. Thus, the tray body 33 can rotate freely around the rotating shaft 244 .

[0028] A discharge barrel 22 can be disposed outside the discharge port 211. The discharge barrel 22 can be generally cylindrical and extend vertically downward around the discharge port 211. The discharge barrel 22 can provide directional guidance for the discharge of the extrusion barrel 2. The lower end of the discharge barrel 22 can be arranged vertically to correspond to the upper surface of the extrusion tray 32 on the multi-position tray 3, so that the lower end of the discharge barrel 22 has an engaging end surface 229 that can be aligned with the upper surface of the extrusion tray 32.

[0029] See also Figure 7 , Figure 7 Shown Figure 2 An enlarged schematic diagram of part C in the figure. In some embodiments, a connecting ring 221 may be provided on the vertical lower side of the discharge barrel 22. The connecting ring 221 may be roughly formed into a circular ring with its axis vertically aligned in the vertical direction. Its circumferential outer wall may have the same diameter as the outer wall of the main body of the discharge barrel 22, while its circumferential inner wall may have a smaller diameter than the inner diameter of the discharge barrel 22. Thus, a joint end face 229 is formed between the bottom side of the discharge barrel 22 and the connecting ring 221. At the same time, the inner diameter of the discharge barrel 22 may be smaller than the outer diameter of the above-mentioned extrusion disc 32, while the inner diameter of the connecting ring 221 may be larger than the outer diameter of the extrusion disc 32. This allows the extrusion disc 32 to be at least partially accommodated inside the connecting ring 221, and the joint end face 229 may be used to abut against the upper surface of the extrusion disc 32.

[0030] The bottom side of the connecting ring 221 may also be provided with a positioning mechanism for positioning the material extrusion tray 32. For example, the positioning mechanism may include a positioning notch 222 extending radially through the sidewall of the connecting ring 221. The positioning notch 222 may have a rectangular cross-section, open vertically downward, and extend toward the switching fixed seat 24. The width of the positioning notch 222 may be adapted to the width of the support rod 331 of the multi-position material tray 3, so that the support rod 331 of the multi-position material tray 3 can be snapped into the positioning notch 222, thereby positioning the multi-position material tray 3 in the rotational direction.

[0031] Each extrusion tray 32 can be configured to have multiple extrusion holes located at the center of the tray surface. These extrusion holes are used to form a material diameter that matches the shape and size of the extrusion holes when the material is extruded through the extrusion tray 32. In some embodiments, the tray body 33 can include four extrusion trays 32 spaced 90 degrees apart. Furthermore, the extrusion holes on each extrusion tray 32 can have different apertures. For example, the four extrusion trays 32 can be sequentially provided with a plurality of first extrusion holes 321, second extrusion holes 322, third extrusion holes 323, and fourth extrusion holes 324, wherein the first extrusion hole 321 has a smaller aperture than the second extrusion hole 322, the second extrusion hole 322 has a smaller aperture than the third extrusion hole 323, and the third extrusion hole 323 has a smaller aperture than the fourth extrusion hole 324. This allows the tray body 33 to be rotated using the aforementioned rotating shaft 244 to align the extrusion trays 32 with the discharge port 211, allowing for quick adjustment of the extrusion aperture. In addition, in some embodiments, the extrusion hole may also have other different shapes, such as an elliptical or rectangular shape, and the extrusion hole provided on each extrusion disk 32 has a shape different from the extrusion holes on other extrusion disks 32 .

[0032] In some embodiments, a feeding hopper may be provided on the upper side of the feed port 21. The feeding hopper may be configured as a funnel with a larger cross section at the top and a smaller cross section at the bottom to facilitate collection of the input materials and avoid pollution or waste caused by splashing or falling of the materials outside the feed port 21.

[0033] It will be understood by those skilled in the art that, although a method of positioning by means of a rectangular positioning notch 222 and a multi-position material tray 3 having a support rod 331 is shown above, the present disclosure does not limit the specific positioning method of the multi-position material tray 3. For example, the positioning notch 222 can be set to have a circular or other shaped cross-section, and the support rod 331 can also be of other shapes, such as a circular rod, etc., as long as the positioning notch 222 can form a circumferential positioning for the support rod 331. At the same time, the multi-position material tray 3 can also be formed in other forms. For example, it can be positioned not by the support rod 331, but by providing other positioning mechanisms arranged in the vertical direction, such as positioning pins or positioning holes. At the same time, the bottom side of the connecting ring 221 can also be provided with corresponding positioning pins or positioning grooves to form positioning with the corresponding positioning mechanisms on the multi-position material tray 3.

[0034] In some embodiments, a limiting groove 325 is further provided on the circumferential outer side of the extrusion disc 32. At the same time, a pin hole 226 corresponding to the limiting groove 325 and extending through the side wall can be provided on the circumferential side wall of the connecting ring 221. The movable locking pin 224 for locking the extrusion disc 32 can be movably disposed in the pin hole 226. Specifically, the limiting groove 325 can be, for example, a groove extending along the circumferential outer surface of the extrusion disc 32 toward the center of the extrusion disc 32, with a cross-section that is roughly rectangular. The movable locking pin 224 can be shaped to match the limiting groove 325. The movable locking pin 224 can also be shaped to match the pin hole 226 on the connecting ring 221. After the movable locking pin 224 passes through the pin hole 226 and extends into the limiting groove 325, the extrusion disc 32 and the connecting ring 221 can be relatively locked, preventing the multi-position disc 3 from continuing to rotate.

[0035] A guide member 223 may be further provided on the circumferential outer side of the connecting ring 221. The guide member 223 may include, for example, a guide hole 227. The guide hole 227 runs through the entire guide member 223 and communicates with the pin hole 226, allowing the movable locking pin 224 to move between the guide hole 227 and the pin hole 226. The guide hole 227 provides additional guide track length for the movable locking pin 224, making the movement of the movable locking pin 224 more stable. The guide member 223 may be formed to be fixed on the side wall of the circumferential outer side of the connecting ring 221 and surround the outer circumference of the pin hole 226. In some embodiments, the guide member 223 may be formed in a cylindrical shape, including an outer wall formed in a shape such as a cylinder or a prism, and the guide hole 227 may be provided in the central portion thereof.

[0036] In addition, a locking spring 225 may be provided on the outer sidewall of the connecting ring 221 or the discharge barrel 22, and the movable locking pin 224 may further include a spring connecting portion 228 extending perpendicular to the moving direction of the movable locking pin 224. One end of the locking spring 225 may be fixedly connected to the connecting ring 221 or the circumferential sidewall of the discharge barrel 22, while the other end may be fixed to the spring connecting portion 228 of the movable locking pin 224. Thus, the locking spring 225 can provide the locking pin with a continuous spring tension toward the extrusion barrel 2, so that after the movable locking pin 224 is inserted into the limiting groove 325 of the extrusion disc 32 for positioning, the movable locking pin 224 can be stably maintained in the limiting groove 325 by the spring tension. In addition, in some embodiments, the locking spring 225 can also be directly connected to the end of the movable locking pin 224 exposed to the outside of the extrusion barrel 2. In this case, there is no need to set a protruding spring connecting portion 228 on the movable locking pin 224, but only a connecting structure for connecting the locking spring 225 is required. The connecting structure can be, for example, a through hole or a groove.

[0037] In some embodiments, the waste polyester fiber regeneration and extrusion device further includes a bottom bracket 1, wherein the extrusion barrel 2 is disposed above the bottom bracket 1 and connected to the bottom bracket 1 via support columns 12. For example, the bottom bracket 1 may include a horizontally arranged support plate 10, which may be a flat plate in a rectangular shape or other shape. A vertically extending support column 12 is fixedly disposed on the upper side of the support plate 10. One end of the support column 12 is connected to the support plate 10, and the other end may be connected to the bottom of the extrusion barrel 2. In some embodiments, the number of support columns 12 may be two or more to provide more support points for the extrusion barrel 2 along the axis of the extrusion barrel 2 and to distribute the pressure exerted on a single support column 12. A relief groove 13 may be provided in the portion of the support plate 10 vertically corresponding to the discharge port 211 of the extrusion barrel 2. The relief groove 13 may be, for example, a rectangular notch formed in the corresponding portion, and the relief groove 13 opens toward a lateral edge of the support plate 10. Thus, when discharging materials through the discharge port 211, the material receiving and transferring equipment can be brought close to the discharge port 211, facilitating the collection and transfer of materials. Furthermore, a plurality of support legs 11 can be provided on the underside of the support plate 10. When the support plate 10 is rectangular, the plurality of support legs 11 can be provided, for example, at the four corners of the rectangular support plate 10, thereby providing stable support for the waste polyester fiber regeneration and extrusion device.

[0038] During operation, melted raw materials are fed into the extruder barrel through the hopper. The drive actuator is then activated, rotating the output shaft and the extrusion blades. The melted raw materials are mixed within the extruder barrel and transferred to the discharge barrel, where they are extruded into strips through the first extrusion hole on the extrusion disc. To change the extrusion aperture, first pull the movable locking pin to disengage it from the retaining groove in the extrusion disc, unlocking the disc from the connecting ring. The multi-position disc can then be moved downward, driving the four extrusion discs downward. Once the discs are clear of the connecting ring, the main body of the multi-position disc is rotated 90°. The disc with the second extrusion hole on the main body moves below the connecting ring. Under the tension of the switching spring, the spring retainer moves the multi-position disc upward, moving it into the inner side of the connecting ring. At this point, the movable locking pin is released, and one end of the pin engages the retaining groove, securing the discs and completing the aperture change.

[0039] The extrusion equipment for recycling waste polyester fibers disclosed herein utilizes an extrusion switching mechanism to switch between multiple extrusion discs with various extrusion orifices, enabling the production of products with a wide range of specifications. This improves the adaptability of waste polyester fiber recycling production and, because it can replace existing equipment designed to produce polyester fiber products of varying outer diameters, also saves equipment costs and the labor costs associated with equipment replacement and maintenance.
