Description

Technical Field

[0001] This invention relates to the field of polyester waste filament recycling technology, specifically to a waste filament recycling equipment and operating process for blended polyester filaments. Background Technology

[0002] Polyester has a wide range of uses, and is widely used in the manufacture of clothing and industrial products. Flame-retardant polyester has a wide range of applications due to its flame-retardant properties. Besides playing an irreplaceable role in industrial textiles, architectural interiors, and vehicle interior decoration, it also plays a significant role in protective clothing. Due to the wide range of applications and material properties of polyester filament, it has high recycling value. In the recycling and reuse of blended polyester filament, a cutting device is used. In existing polyester filament cutting devices, the polyester filament is conveyed by a conveyor mechanism to the area below a reciprocating cutter. However, because polyester filament has a certain degree of expansion, if there is a large amount of polyester filament on the conveyor mechanism, the expansion height is high, which is not conducive to cutting. Generally, a pressure roller assembly is installed in front of the cutter to compress the polyester filament entering below the cutter downwards. If the amount of polyester filament is large, the expansion height is too high, and it is easy for it to accumulate at the pressure roller. The reason for the accumulation is that the polyester filament cannot pass normally under the pressure roller, and due to slippage, the polyester filament moves upwards towards the pressure roller. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a waste fiber recycling processing equipment and operating process for blended polyester filaments, which solves the problem that the high expansion height of polyester during the conveying process in existing blended polyester filament waste fiber recycling and cutting processing equipment is not conducive to cutting.

[0006] Preferably, the auxiliary component includes a hollow shaft, which is rotatably connected to the top of the inner wall of the support frame.

[0012] This invention also discloses a process for recycling waste polyester filament, specifically including the following steps:

[0013] Step 1: Remove the impurities from the recycled polyester waste yarn and put it into the washing tank for cleaning. After cleaning, spin dry.

[0014] Step 2: The spun-dry polyester waste yarn is placed into the waste yarn processing equipment of blended polyester filament for cutting. Before cutting, the polyester waste yarn is compressed by the pre-compression mechanism and the side compression mechanism to expand vertically and horizontally, so that the polyester waste yarn can enter the pressure roller assembly normally. Finally, the polyester waste yarn is cut into broken yarns with a length of 7-12mm by the up-and-down moving cutter.

[0019] Beneficial effects

[0020] This invention provides a processing equipment and operating procedure for recycling waste polyester filament. Compared with the prior art, it has the following advantages:

[0021] 1. The waste polyester filament recycling equipment and operating process of this blended polyester filament uses a pre-compression mechanism set in front of the pressure roller assembly to compress the polyester waste filament downwards before it enters the pressure roller assembly. This avoids the problem that the polyester waste filament cannot enter the pressure roller correctly due to its high expansion, and also avoids the problem of polyester waste filament accumulating at the pressure roller, thus improving the reliability of the processing equipment.

[0022] 2. The waste fiber recycling equipment and operating process of this blended polyester filament uses a connecting component to connect the T-shaped pressure plate with two L-shaped connecting rods on the left and right sides, thereby driving the T-shaped pressure plate to move up and down. The T-shaped pressure plate can also rotate. In addition, when the T-shaped pressure plate is damaged, the T-shaped sliding rod, arc plate and limit spring inside the connecting component can be used to disassemble and replace the T-shaped pressure plate, which improves the convenience of using the equipment.

[0023] 3. The waste fiber recycling equipment and operation process of this blended polyester filament, through the set auxiliary components, allows the T-shaped pressure plate to rotate 180 degrees immediately after moving to the top, so that the bottom of the T-shaped pressure plate comes into contact with the second scraper, thereby scraping off the polyester waste fiber adhering to the bottom of the T-shaped pressure plate, avoiding the problem of a large amount of waste fiber adhering to the bottom of the T-shaped pressure plate.

[0024] 4. The waste polyester filament recycling equipment and operating process, through the side compression component, makes the left and right side pressure plates approach the polyester waste filament while the T-shaped pressure plate moves downward, squeezing the amount of expansion of the polyester waste filament to the left and right, thereby avoiding the problem that the polyester waste filament cannot enter the pressure roller due to excessive expansion on the side, and further ensuring that the polyester waste filament can be cut normally in the subsequent process.

[0025] 5. The waste fiber recycling equipment and operation process of this blended polyester filament uses a first scraper to clean the surface of the pressure roller in the pressure roller assembly, so as to avoid a large amount of waste fiber adhering to the surface of the pressure roller. In addition, the position of the first scraper can be adjusted to ensure that the bottom of the first scraper can still make good contact with the surface of the pressure roller after wear.

[0037] 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.

[0038] The waste fiber recycling equipment for this blended polyester filament offers five technical solutions:

[0039] like Figure 1-3The first embodiment is shown: it includes a protective housing 1 with a cutting assembly inside, a conveying mechanism 2, and a pressure roller assembly 3. A cleaning assembly 4 is provided above the pressure roller assembly 3 to clean the surface of the pressure roller assembly 3. A pre-compression mechanism 5 is provided above the conveying mechanism 2 to pre-compress waste polyester filaments, and the pre-compression mechanism 5 is located at the inlet of the protective housing 1. The pre-compression mechanism 5 includes a support frame 51, which is fixedly connected to the top of the conveying mechanism 2. A rotating shaft 52 is rotatably connected between the left and right sides of the inner wall of the support frame 51. Both ends of the rotating shaft 52 pass through the support frame 51 and extend to the left and right sides of the support frame 51, respectively. Both ends of the rotating shaft 52 are fixedly connected to a disc 54. The two discs 54 are open on opposite sides. The support frame 51 is provided with a limiting groove 55. The left and right sides of the support frame 51 are rotatably connected to the swing rods 56. The opposite sides of the two swing rods 56 are fixedly connected to the limiting blocks 57. The left and right limiting blocks 57 are respectively located inside the left and right limiting grooves 55, thereby realizing the up and down swing of the other end of the swing rods 56. The other end of the swing rods 56 is provided with a sliding groove 58. The limiting blocks 57 are slidably connected to the L-shaped connecting rods 59 through the sliding grooves 58. The other ends of the two L-shaped connecting rods 59 are connected to the detachable T-shaped pressure plates 510 through the connecting components 6. The T-shaped pressure plates 510 are provided with an auxiliary component 7 above them for scraping and cleaning the bottom of the T-shaped pressure plates 510. The T-shaped pressure plates 510 are provided with two side compression components 8 below them for compressing the sides of the polyester waste yarn.

[0040] By setting a pre-compression mechanism 5 in front of the pressure roller assembly 3, the polyester waste yarn is compressed downward before entering the pressure roller assembly 3, thereby avoiding the problem that the polyester waste yarn cannot enter the pressure roller correctly due to its high expansion, and also avoiding the problem of polyester waste yarn accumulating at the pressure roller, thus improving the reliability of the processing equipment.

[0041] like Figure 2 , 4 5 and 6 indicate the second implementation method. The main difference from the first implementation method is that the connecting component 6 includes a rhombus block 61. A circular through groove 62 is provided at the middle position of the top of the rhombus block 61. Four grooves 63 are provided at equal intervals inside the rhombus block 61. The grooves 63 are connected to the circular through groove 62. Two T-shaped slide rods 64 are fixedly connected to the right side of the inner wall of the groove 63. An arc plate 65 is slidably connected to the surface of the two T-shaped slide rods 64. A limiting spring 66 is sleeved on the surface of the T-shaped slide rods 64 outside the arc plate 65. A round block 67 is fixedly connected to the surface of the T-shaped pressure plate 510. A circular groove 68 that cooperates with the arc plate 65 is provided on the surface of the round block 67.

[0042] The T-shaped pressure plate 510 is connected to the two L-shaped connecting rods 59 on the left and right by the connecting component 6, which can drive the T-shaped pressure plate 510 to move up and down, and the T-shaped pressure plate 510 can also rotate. In addition, when the T-shaped pressure plate 510 is damaged, the T-shaped sliding rod 64, the arc plate 65 and the limit spring 66 set inside the connecting component 6 can disassemble and replace the T-shaped pressure plate 510, which improves the convenience of using the equipment.

[0043] like Figure 2 and 7 The third embodiment is shown, and its main difference from the second embodiment is that the auxiliary component 7 includes a hollow shaft 71, which is rotatably connected to the top of the inner wall of the support frame 51. Multiple limiting cylinders 72 are fixedly connected at equal intervals on the surface of the hollow shaft 71. A rotating rod 73 is rotatably connected between the left and right sides of the inner wall of the support frame 51. A drive wheel 75 is fixedly connected to the middle position of the surface of the rotating rod 73. Multiple guide grooves 76 are equidistantly arranged on the surface of the drive wheel 75. The guide grooves 76 cooperate with the limiting cylinders 72. A spline shaft 77 is slidably connected to the inner surface of the hollow shaft 71. One end of the spline shaft 77 located below the hollow shaft 71 is fixedly connected to the top of the T-shaped pressure plate 510. A second scraper 78 is fixedly connected between the left and right sides of the inner wall of the support frame 51.

[0044] A first gear 53 is fixedly connected to the surface of the rotating shaft 52, a second gear 74 is fixedly connected to the surface of the rotating rod 73, a drive motor 9 is fixedly connected to the left side of the inner wall of the support frame 51, and a drive gear 10 is fixedly connected to the output end of the drive motor 9. Both the first gear 53 and the second gear 74 mesh with the drive gear 10 for transmission.

[0045] By using the auxiliary component 7, the T-shaped pressure plate 510 rotates 180 degrees immediately after moving to the top, so that the bottom of the T-shaped pressure plate 510 contacts the second scraper 78, thereby scraping off the polyester waste filaments adhering to the bottom of the T-shaped pressure plate 510 and avoiding the problem of a large amount of waste filaments adhering to the bottom of the T-shaped pressure plate 510.

[0046] like Figure 1 , 2The fourth embodiment is shown in Figure 8. The main difference between this embodiment and the third embodiment is that the side compression assembly 8 includes two racks 81, one upper and one lower. Both racks 81 are slidably connected to the left side of the support frame 51. Both racks 81 pass through the support frame 51 and extend into the interior of the support frame 51. A side pressure plate 82 is fixedly connected to one end of the lower rack 81 inside the support frame 51, and an inclined plate 83 is fixedly connected to one end of the upper rack 81 inside the support frame 51. A baffle 84 is fixedly connected to the left side of the support frame 51, and a fixing rod 85 is fixedly connected to the back of the baffle 84. An intermediate gear 86 is rotatably connected to the surface of the fixing rod 85. Both the upper and lower racks 81 mesh with the intermediate gear 86 for transmission. A torsion spring 87 is sleeved on the surface of the fixing rod 85 in front of the intermediate gear 86. One end of the torsion spring 87 is fixedly connected to the front of the intermediate gear 86, and the other end of the torsion spring 87 is fixedly connected to the surface of the fixing rod 85.

[0047] By using the side compression component 8, as the T-shaped pressure plate 510 moves downward, the two side pressure plates 82 on the left and right sides approach the polyester waste yarn, squeezing the amount of expansion of the polyester waste yarn on the left and right sides. This avoids the problem that the polyester waste yarn expands too much on the side and cannot enter the pressure roller, and further ensures that the polyester waste yarn can be cut normally in the subsequent process.

[0048] like Figure 9 and 10 The fifth embodiment is shown. The main difference between the fifth and fourth embodiments is that the pressure roller assembly 3 is mounted on two rotatable lead screws on the left and right. The rotation of the lead screws drives the pressure roller assembly 3 to move up and down. The cleaning assembly 4 includes two U-shaped plates 41 on the left and right. Both U-shaped plates 41 are threadedly connected to the surface of the lead screws that drive the pressure roller assembly 3 to move up and down. An adjusting lead screw 42 is rotatably connected between the top and bottom of the inner wall of the U-shaped plate 41. The adjusting lead screw 42 passes through the U-shaped plate 41 and extends to the top of the U-shaped plate 41. A connecting block 43 is threadedly connected to the surface of the adjusting lead screw 42. A first scraper 44 is fixedly connected between the opposite sides of the two connecting blocks 43.

[0049] The first scraper 44 is used to clean the surface of the pressure roller in the pressure roller assembly 3, so as to avoid a large amount of waste filaments adhering to the surface of the pressure roller. In addition, the position of the first scraper 44 can be adjusted to ensure that the bottom of the first scraper 44 can still make good contact with the surface of the pressure roller after wear.

[0050] This invention also discloses a process for recycling waste polyester filament, specifically including the following steps:

[0051] Step 1: Remove the impurities from the recycled polyester waste yarn and put it into the washing tank for cleaning. After cleaning, spin dry.

[0052] Step 2: The spun-dry polyester waste yarn is placed into the waste yarn processing equipment of blended polyester filament for cutting. Before cutting, the polyester waste yarn is compressed by the pre-compression mechanism and the side compression mechanism to expand vertically and horizontally, so that the polyester waste yarn can enter the pressure roller assembly normally. Finally, the polyester waste yarn is cut into broken yarns with a length of 7-12mm by the up-and-down moving cutter.

[0053] The specific operating process of the waste polyester filament recycling equipment is as follows: The waste polyester filament is placed into the conveyor mechanism 2. The conveyor mechanism 2 is started to move the waste polyester filament. When it enters below the T-shaped pressure plate 510, the drive motor 9 is started. The drive motor 9 rotates, driving the drive gear 10 to rotate. The drive gear 10 rotates and transmits power to the support frame 51. The first gear 53 rotates, driving the rotating shaft 52 to rotate. The rotating shaft 52 rotates, driving the two discs 54 to rotate simultaneously. The rotation of the discs 54, combined with the pre-compression mechanism 5 and the limiting block 57, causes the other end of the swing rod 56 to swing up and down. The swing rod 56 swings up and down, thereby driving the T-shaped pressure plate 510 to move up and down. When the T-shaped pressure plate 510 moves upward, it compresses the waste polyester filament downward, allowing the waste filament to enter normally below the pressure roller. Simultaneously, while the drive gear 10 rotates, it transmits power to the second gear 74. The second gear 74 rotates, driving the rotating rod 73 to rotate. The rotating rod 73 rotates and drives the drive wheel 75 to rotate. Through the cooperation of the guide groove 76 and the limiting cylinder 72, when the T-shaped pressure plate 510 is at its highest position, it rotates 180 degrees. When the T-shaped pressure plate 510 rotates, the ground contacts the second scraper 78, thereby scraping off the waste wires adhering to the bottom of the T-shaped pressure plate 510 and causing them to fall into the moving waste wires. When the T-shaped pressure plate 510 moves downward, it contacts the tops of the two inclined plates 83 on the left and right, thereby pushing the two inclined plates 83 away from each other. The inclined plate 83 moves, causing the rack 81 connected to it to move. The rack 81 moves, causing the fixing rod 85 to rotate. The rotation of the fixing rod 85 causes the lower rack 81 to move in the direction of the fixed rod 85, thereby pushing the two side pressure plates 82 close to the sides of the polyester waste yarn. When the T-shaped pressure plate 510 moves upward, the fixing rod 85 is flipped by the left and right sides of the torsion spring 87, thereby resetting the inclined plate 83 and the side pressure plates 82. After passing through the pressure roller assembly 3, the polyester waste yarn enters the cutter position and is cut.

[0054] In addition, the T-shaped pressure plate 510 can be disassembled. When disassembling the T-shaped pressure plate 510, the four arc-shaped plates 65 enter the groove 63, so that the arc-shaped plates 65 are separated from the annular groove 68. At this time, the T-shaped pressure plate 510 can be removed from the diamond block 61.

[0055] When the pressure roller in the pressure roller assembly 3 rotates, the surface of the pressure roller is scraped and cleaned by the first scraper 44 above. In addition, rotating the adjusting screw 42 allows the first scraper 44 to move up and down, thereby adjusting so that the first scraper 44 can maintain good contact with the surface of the pressure roller.

[0056] Step 3: The cut waste filaments are fed into the bubble material making machine, where they rotate and heat up. As the temperature rises, the waste filaments soften and bind together into large granules, which are then poured into water to obtain small granules, which are the bubble material.

[0057] Step 4: Add the foam material obtained in Step 3 to the crystallization bed through a rotary valve, maintain a boiling state, the thickness of the material layer in the crystallization bed is 10-20 cm, the crystallization time is 40-55 min, and the crystallization temperature is 170-175℃.

[0058] Step 5: Dry the crystals from Step 4 and put them into extrusion and melt preparation to obtain a mixed melt.
